In laying before the public the AMERICAN ECLECTIC DISPENSA- TORY, we are fully aware that the profession have been abundantly supplied with similar works of a high scientific character, which would leave no excuse for the publication of another, unless it should present important information not contained in the standard works. It may not be known to some of the readers of this work, that a great amount of highly important knowledge, in reference to the Therapeutic value of remedies, and especially of our native-American plants, has been accumulated by liberal- minded physicians in America; which knowledge, owing to various causes, has never yet been sufficiently brought before the medical profession generally, and has not been embodied in the voluminous standard works of Pereira, Wood and Bache, Dunglison, etc. This knowledge being especially American in its origin, and having produced a marked peculiarity in the practice of a large number of American physicians, we deem it proper to style this work the " American Eclectic Dispensatory," to distinguish it from other works, which contain only the ideas or views which are common to both American and European physicians. Another urgent reason for the publication of this work, lies in the fact, that the important improvements and discoveries of American Eclectic physicians have not only been, to a great extent, overlooked by authors, but have already begun to find their way into medical works without any reference whatever to their paternity ; and in some instances, articles familiarly known and used for twenty years past by Medical Reformers, have been gravely brought forward as new discoveries. The use of the term Eclectic, in our title, implies something more than what we usually associate with that word as a common adjective. It refers to the existence of a large class of physicians in America, who believe that the profession has been too much trammeled by the influence of authority, and by the disposition to impose upon the young members of the profession, certain scientific and ethical doctrines which their seniors have sanctioned ; thus reduc- ing a noble profession, with a comprehensive science, to the character of a sect, with certain cherished dogmas. American Eclecticism is thus opposed to medical sectarianism, and especially to that most oppressive form of secta- rianism, which, like the Roman Hierarchy, denying that it is sectarian, assumes to be an embodiment of unquestionable truth, and pronounces the medical system which may be sanctioned by the majority of the present generation, a standard of scientific truth, from which any deviation, or even the expression of dissent, should be condemned and punished by professional and even social ostracism. (iii) • Preface. This assumption of infallibility, in the existing and prevalent system of the rapeutics, or rather, of the right to enforce its acceptance, by dishonoring al who dissent from its doctrines, is too extravagant to bear the test of serious examination. No one who is familiar with medical history who recollects the incessant changes in medical doctrines and practice from the days of tra- in's infallibility to the present time, and who remembers how sternly the main body of the profession have rejected and condemned the doctrines which their successors were compelled to adopt, can suppose that a profession so very fallible in all past time, has even yet acquired infallibility; nor can any one seriously believe it, when he observes in the doctrines and practice of the present day the same slow, steady, progressive change as in past times. And if the idea of doctrinal infallibility as to Therapeutics, either in the mass of the profession or in its most gifted leaders, be, in fact, too absurd for serious argument, what possible foundation can there be for the assumption that truth- fulness and professional respectability belong exclusively to the majority, and to their transitory doctrines, and that any different scientific doctrines should be branded as empirical and disreputable? Such assumptions, being essentially absurd and groundless, are based now, as they always have been, on that arrogant and intolerant element of human nature, which leads all large masses of men to attempt to enforce conformity to their own sentiments, and to dishonor all that opposes them—as an Egyptian rabble hoot at a passing Christian. The liberal and humane spirit of the age is opposed to such intolerance, and demands that sectarians in theology and in science shall extend mutual toleration to each other. This toleration is demanded not only by sound morals, by the spirit of hu- manity and the amenities of social life, but by justice to truth ; for as no sect or doctrine can be based exclusively upon falsehood, and as it is certain that whatever has been received by any considerable number of men must contain an appreciable amount of truth, true philosophy dictates that we should receive and examine with candor all medical doctrines, not only through cour- tesy to their supporters, but for the sake of profiting by their truths. This duty is especially urgent when the supporters of such doctrines claim to have achieved much good by their medical practice; and if their claims are well- grounded, we should be culpable indeed, in neglecting to avail ourselves of the instruction which they proffer for the sake of humanity. Those physicians who, in America, have been most zealous in maintaining these liberal principles, have been called Eclectics, and the principal school in which such doctrines have been taught has been called the " Eclectic Med- ical Institute." It is true, that many physicians have contended that the whole profession should be Eclectic, and that some even maintain that it is at present Eclectic, and liberally examines or adopts whatever may be presented that is new and true. It is true, that the profession is not totally destitute of the spirit of Eclecticism, for such destitution would imply a total destitution of liberality, but we cannot recognize Eclectic liberality in those who treat with bitter scorn the personal and professional characters of scientific physi- cians whose doctrines differ from the more prevalent views of therapeutics, and who, instead of recommending, endeavor to discourage or prevent the free examination of what they consider heretical doctrines, and who attach profes- sional penalties to the avowal of what they deem heretical sentiments. If the Preface. v investigation of different medical doctrines is to be carried on under the threat of professional excommunication, unless certain conclusions are adopted and if as has been recently arranged in certain medical colleges, the young practitioner shall be entitled to hold his diploma only so long as he adheres to certain opinions, there is no more freedom of investigation conceded on medical sub- jects than there would be freedom of suffrage when the polls were overawed by the bayonets of one of the candidates. In extending our personal courtesy and professional liberality to the followers of Hahnemann, Priessnitz, and minor leaders of medical parties, we are merely obeying the positive dictates of morality and religion, which forbid unkind, illiberal sentiments; and as the time must come when all that has been devel- oped by the labors of medical sectarians shall be incorporated with the estab- lished mass of recognized science, it is unwise and injurious to the progress of the profession to delay such incorporation by encouraging animosities and isolation among the cultivators of medical science. Such is the kindly and harmonious spirit which American Eclectics desire to see introduced into the profession ; but in addition to these ethical improve- ments, they desire a more faithful and prompt adherence to the dictates of Clinical experience. There are many changes in the details of medical prac- tice, the value of which has been amply demonstrated by experience, in the various climates of the United States, but which have not yet been adopted by the profession generally, because they are not yet sufficiently known and understood by those who have not been pupils of the Eclectic Medical Insti- tute. For the nature of these improvements, and their gratifying results in the treatment of disease, we must refer to the "American Eclectic Practice, by Professors Jones and Morrow," the " Eclectic Practice of Medicine, by Professors Newton and Powell," as well as the "Lectures on the American Eclectic System of Surgery, by Professor Hill," and the forthcoming system of Eclectic Obstetrics, by the author of the present volume. For further information of the Eclectic system, we would refer to the prac- tice of Eclectic physicians, and to the Lectures of the Institute. This College, chartered in 1845, has been for some years the leading Medicai College of the West, in point of numerical attendance ; the whole number of matriculants in 1852-3, and 1853-4, was six hundred, and the whole number of graduates amounted to one hundred and thirty-three. We make this reference because the highest evidence of the value of Eclecticism is found in the successful treatment of disease by Eclectic physicians ; in the treatment of 1503 cases of cholera in Cincinnati, in 1849, with a mortality of only 65, and many analogous facts, which will hereafter be more fully authenticated. These great practical improvements are simply the fruits of patient and faithful attention by numerous physicians to the results of experience, and the liberal spirit of the Faculty of the Institute, who have not disdained to gather knowledge from any source. We should not overlook, in our passing reference, the distinguished services of individuals who, if they were not like Hahnemann or Dixon, the authors of a special and exclusive theory of therapeutics, have the more exemplary merit of faithful scientific observation in a liberal and candid spirit of improve- ment, and the honor of arranging and presenting before the public, with untiring energy and unshrinking moral courage, a mass of science much in advance of prevalent ideas, and consequently greatly embarrassed by the habitual, resolute vi Preface. opposition of conservative minds. We allude especially to Dr. Thomas V. Morrow, to whose reputation as a practitioner, and untiring zeal as a med- ical professor, we are mainly indebted for the establishment and maintenance of a school devoted to the Eclectic system of medicine at Worthington, Ohio, and the subsequent successful establishment of the Eclectic Medical Institute of Cincinnati. This reference to Professor Morrow is especially demanded by the fact that so little has been left from his pen to bear witness to the value of his services as a medical teacher and pioneer laborer in medical reform and improvement. His distinguished co-laborers, Professors J. R. Buchanan and I. G. Jones, have already, by their pens, made known to medical readers their conspicuous agency in medical progress. We are greatly indebted to Professor Buchanan, the present Dean of the Institute, for his able and zealous services, especially since 1846, in maintain- ing the success, the reputation and unity of the Institute, and shaping its pol- icy, while at the same time he has been known as a peculiarly original and philosophic teacher of medicine, and most distinguished exponent, before the public, of the philosophy of Eclecticism. To Professor I. G. Jones, we are greatly indebted as an early co-laborer of Professor Morrow, at Worthington ; as an eminent and veteran practitioner ; an able teacher of medical practice, and a successful author, whose writings will contribute much to the diffusion and adoption of the improved system of thera- peutics, the value of which has been so well displayed in his own practice. If the Eclectic improvements in medicine are even one half of what is be- lieved by those who have personally tested them, they who have devoted their best energies and risked the entire loss of reputation for the sake of such truths, will be gratefully remembered by posterity, and the names of Morrow, Buchanan and Jones, with their coadjutors and successors in the labor of scientific reform, will be held in distinguished honor. To this cause, the author of the present volume has been devoted for about twenty years as a medical practitioner, and latterly as a medical professor and author, and he wishes no higher honor than to be recognized as one of those who, at the commencement of the Eclectic movement, have participated in the labors of its pioneers. An important characteristic of American Eclecticism, which may be illus- trated by this volume, is the superior zeal displayed by Eclectic physicians in making important and much needed improvements in the Materia Medica, and especially in developing the medicinal value of our native plants. There are many results attainable in practice, by the use of these new resources, which could not be satisfactorily realized by the agents in ordinary use. One of these important results is the ability to dispense partially, if not wholly, with various unsafe or deleterious agents, and accomplish the purposes for which they are used by safer and more scientific treatment. We say more scientific, because that is certainly the most scientific prescription which accomplishes the object desired without incidentally inflicting unnecessary injury. The many inconveniences and dangers attending the use of mercurial medicines have produced a strong desire to find some safe and efficient substitute. There is no single remedy ever known to man which has produced a greater amount of mischief by its indiscriminate use than Mercury; nor is there any other drug which has done one-hundredth part as much to create a prejudice against Preface. vii scientific medicine, to destroy the confidence of the community in its practition- ers, and to repel them from the physician to the nostrum-dealer. But with the mass of the profession, the desire to find a substitute for Mercury has been rather an idle fancy than a positive desire or purpose, and has produced no result whatever. Indeed, the conviction still prevails, that no substitute for mercury can be found, and we regret to record the fact, in the year 1854, that medical schools and medical authors generally, still regard mercury as the only powerful and reliable cholagogue, simply because they are not acquainted with the powers of other agents ; the most specific cholagogue known, Leptandrin, not having obtained a place in any but the Eclectic Dispensatory, and Leptandra itself having been excluded from the U. S. Pharmacopoeia and the officinal part of the U. S. Dispensatory, on account of its supposed worthlessness. Leptan- drin, Podophyllin, Apocynin, and Iridin, with Sanguinaria, Taraxacum, Ber- beris, and Euonymus, and occasional combinations of other articles, accomplish far more than Mercury performs, in the way of arousing the liver, affecting the secretions generally, and even producing salivation of a harmless character. It is not merely in substitutes for mercurials, and for various prescriptions which the physician uses with caution, and without entire satisfaction, that the improvement of the Eclectic Materia Medica consists, but also in the intro- duction of agents and powers of a novel character, or the extensive applica- tion of articles previously little known and seldom used. Of articles, pre- viously little known or used by the profession, which are extensively used by Eclectic physicians, we may enumerate: Achillea, Cypripedium, Leonurus, Pteris, Actaea, Daucus, Leptandra, Pterospora, Adiantum, Diervilla, Liatris, Pycnanthemum, Aletris, Dioscorea, Ligustrum, Pyrola, Alnus, Epigsea, Liquidambar, Rhus, Althaea, Erechthites, Liriodendron, Uobinia, Amaranthus, Erigeron, Lobelia, Rubus, Ampelopsis, Eryngium, Lycopus, Rudbeckia, Apocynum, Erythronium, Lythrum, Rumex, Aralia 's, Euonymus, Marrubium, Sabbatia, Arum, Eupatorium, Menispermum, Salix, Asarum, Euphorbia, Menyanthes, Sanicula, Asclepias, Frasera, Mitchella, Saponaria, Aster, Fraxinus, Monotropa, Scutellaria, Baptisia, Galium, Myrica, Senecio, Berberis, Gelseminum, Nymphsea, Silphium, Betula, Geranium, Onosmodium, Solidago, Bidens, Gerardia, Orobanche, Spiraea, Buxus, Geum, Osmunda, Spirit Vapor Bath.

Together with numerous others not herein referred to. Vlll It is true, that Preface. a number of the foregoing articles have been referred to by medical writers, and a few have been occasionally used in practice, but in gene- ral, they have been located at the extreme verge of the visible horizon of the profession—in the outside regions of empiricism unknown to the mass of phy- sicians, and but slightly known to any who were not especially addicted to botanical pursuits. The honor of their introduction into regular medical prac- tice, belongs to the Medical Reformers of America, through whom their virtues have been°made known; and by whom articles have been made prominent and important agents in the Materia Medica, which were previously treated with so much contempt, that a physician felt almost ashamed to investigate their virtues, or acknowledge any acquaintance with them. Of the above articles, or their concentrated principles, which are absolutely and at present confined to the circle of practice of Medical Reformers, by new whom they were introduced, we may mention: Aletridin, Alnuine, Ampelopsis, Antennaria, Apocynin, Asclepias Incar. Asclepidin, Aster, Baptisin, Bidens, Buxus, Caulophyllum, Caulophyllin, Ceanothus, Ceanothine, Chelone, Cimicifugin, Diervilla, Dioscorea, Dioscorein, Echinospermum, Epigaea, Equisetum, Erechthites, Erechthites, oil of, Euonymus, Euonymine, Eupatorin, Eupatorium Purp., Eupurpurin, Galium, Gelseminum, Geraniin, Gerardia, Cornu cervinae calcinatumGoodyera, Corydalis, Helonine, Corydalia, Hieracium, Cypripedin, Hierochloa, Hydrastin, Iridin, Jeffersonia, Juglandin, Leptandrin, Lobelia, oil of, Menisperine, Mitchella, Monotropa, Myricin, Onosmodium, Osmunda, Ostrya, Parthenium, Phytolaccin, Podophyllin, Polemonium, Polytrichum, Prunin, Ptelea, Ptelein, Pteris Atrop., Pterospora, Pycnanthemum, Rhusine, Robinia, Rudbeckia, Scutellarin, Senecin, Sesquicarbonate of potassa Silphium, Spirit vapor bath, Staphylea, Stellaria, Stillingia, oil of, Uvaria, Uvularia, Vernonia, Viburnum, Viburine, Xanthoxylin, and oil of Xanthoxylum, etc The extensive use of the foregoing articles, and their consequent substitu- tion, on many occasions, for the favorite remedies formerly in use, constitutes a practical improvement, the value of which can scarcely be estimated, and the simplest statement of what we believe and know to be true, as regards the superior success in practice resulting from these improvements in the Ma- teria Medica, would be regarded, by those entirely unacquainted with the facts, as the language of extravagant enthusiasm. For their truth, however, we can but appeal to the final tribunal, universal experience; and it is partly with the view of facilitating this appeal by candid physicians, that this volume is laid before the public, in which, we trust, every medical reader will find sufficient information, in reference to the favorite remedies of Eclectic physicians, to enable him to enjoy in practice what we deem the richest fruits of modern clinical experience, constituting the most recent and important practical im- provements in the healing art. It will be seen that the work is divided into three parts: Part I, is devoted to an explanation of the Natural Orders of the various Medicinal Plants named in the work, and which will prove a valuable reference for the practitioner in collecting them; indeed, without this reference the Preface. ix work would have been very imperfect, especially for those who practice as Medical Reformers. Part II, is devoted to the Materia Medica; the various plants are arranged alphabetically, and their Botanical characters are given with sufficient accuracy to enable the medical botanist to select and determine them when met with. The Natural and Artificial classifications of each are mentioned, together with the Vulgar names by which they are known in different sections of our country. A brief reference is likewise made to their general History, with a statement of such Chemical relations and incompatibilities, medically considered, as will be necessary for practical purposes; and as far as known, the Therapeutic influence of each agent is fully but concisely presented. Since the introduction of our new remedies, some of which were discovered and introduced to the profession by the author, as Podophyllin,* Irijjin, Cimicifugin, etc., a great improvement has taken place in Eclectic treatment, and the successful results have been so well marked and undisputed as to have recently invited the investigation of the more liberal old school physicians ; and it is with no little pleasure we state, that already hundreds of them, notwithstanding arbitrary prejudices, are adopting our new remedies, and are gratified by finding them greatly superior to the agents for which they have been substituted. Part III, is occupied principally with Eclectic Pharmacy, and those Prepara- tions only have been described, which an enlarged and successful experience has justly entitled to the rank of officinal; many others might have been men- tioned, but further investigations are required to test their permanent utility. Indeed, the Pharmacy of Eclectic Practice may be said to be almost endless, as a vast amount of agents, both simple and compound, are in constant use, which would require a volume equal in size to the present for their thorough consideration ; and to select from these the more common and successful pre- parations has been a task of no ordinary labor. Our Resinoids, Oleo-resins, etc., which some might deem to be in their proper place only in this part of the work, we preferred to arrange in Part II, accompanying the history, etc., of the plants from which they are obtained. Decoctions and Infusions which are largely used in practice, have been briefly noticed, without any special list, although the general rules for their preparation are laid down ; and wherever there is a departure from these in any article required in infusion or decoction, it will be ascertained under the description of the article in Part II. * Many of our most valuable therapeutical agents have from time to time found tfcoir way into the Old School text-books without due credit having been given to their origin, thus lea'liug many to be- lieve that these agents were discovered and introduced to the profession by Old School physicians; when in truth they were merely transferred from the various reformed publications, to the pag;es of these text-books at different periods, as Reformers made them known. Our Podophyllin, since its value and usefulness have been demonstrated, is about to have the same course pursued with it, as various means are being adopted to bring the credit of its origin into the Old School ranks. In the new edition of (jriffith's Universal Formulary, edited by Dr. Robt. P. Thomas. J. P.. Lewis' method of preparing this retinoid, (a method adopted long after its discovery by the author.) is given, in which it is presented, by imputation, as a pure article; for the editor remarks—''An impure podophyllin has been prepared by VV. S. Merrell, by precipitating the resin from a concentrated alcoholic tincture by the addition of water." But unfortunately for the purity and medicinal activity of Lewis' Podophyl- lin, it requires six grains to act as an ordinary cathartic, while that of Merrell's requires only from half a grain to a grain and a half, thus proving the latter to contain three or four times as much of the medicinal activity of the root as the former. The medical reader will, therefore, please bear in mind the difference between Eclectic Podophyllin, and that claimed by the Old School, as well as the difference in their modes of preparation. X Preface. In the Appendix will be found an amount of selected matter of a valuable character, consisting of Medical Abbreviations and Latin terms; Tables of Weights and Measures ; of Mineral Waters ; Specific Gravities ; Solubility of Salts, etc., which will be of much utility to the chemist and pharmaceutist, and which, we hope, will prove acceptable to all. The Index has been rendered as full and complete as possible, that no diffi- culty may be experienced in readily finding any subject contained in the work. In scientific matters, to write a purely original work is out of the question; authors have to avail themselves of the information and discoveries promul- gated by each other, and in the endeavor to present a complete practical knowl- edge.of medicines, we have not hesitated to consult many excellent authorities ; and though considerable information is introduced not to be had in other publi- cations, yet the only originality claimed is the introduction of New Medicinal Plants; of Concentrated Remedies — their Preparations and uses ; of valuable and Officinal Eclectic Pharmaceutic Preparations ; the selection and disposition of the matter, and the endeavor to systematically methodize the hitherto crude material floating among Eclectics, as well as to rectify the irregular classification of many valuable remedies, thus preserving for Eclecticism the proper credit for all to which it is justly entitled. And as Eclecticism has heretofore, by silence, lost much of the credit to which it was justly entitled, it is hoped that this work, by a systematic presentation of its ample and original resources, may serve to secure the honor of medical improvements to their true sources. We acknowledge our indebtedness to the following authorities, which have been freely consulted and selected from, viz : United States Pharmacopoeia, United States Dispensatory, Christison's Materia Medica, Griffith's Medical Bot- any, Edwards' and Vavasseur's Materia Medica, Mitchell's Therapeutics, Dun- glison's New Remedies, Barton's Collections, Eberie's Practice, Thatcher's Practice, London, Edinburgh, and Dublin Philosophical Magazine, Southern Journal of Medicine and Pharmacy, Silliman's Journal, Boston Medical and Surgical Journal, Dublin Journal of Medical Science, Brande's Manual of Pharmacy, Dublin Pharmacopoeia, London Dispensatory, Gray's Botany of the Northern United States, Mohr and Redwood's Pharmacy by Procter, Journal de Pharmacie, Philosophical Magazine, Pereira's Materia^Medica, Medicul Ex- aminer, Chemical Gazette, Wood's Class-Book of Botany, Woodville's Medical Botany, Bigelow's Vegetable Materia Medica, American Journal of Pharmacy American Journal of Medical Sciences, Braithwaite's Retrospect, London Lan- cet, Eaton's Botany, Lindley's Medical Flora and Vegetable Kingdom, Merat and De Len's Dictionnaire de Matiere Medicale, Rafinesque's Medical Flora Smith's Botanic Physician, Howard's Botanic Practice, Western Medical Re- former, Eclectic Medical Journal, Jones and Morrow's American Eclectic Prac- tice Newton and Powell's Eclectic Practice, Hill's Eclectic Surgen etc eV We are likewise under many obligations to Mr. W.

Milton Sanders for the formula of sev- eral new salts recently discovered by him, and some of which have bo,n suc- cessfully employed as remedial agents. We likewise return our thanks to those members of the profession who have imparted to us new and useful medica inflation, or who have in any way contributed to aid us in the pre]^Zt THE AMERICAN ECLECTIC DISPENSATORY PAR T I, DESCRIPTION OF THE NATURAL ORDERS OF MEDICINAL PLANTS. The study of Botany is an important part of the Physician's educa- tion, especially the Eclectic Physician, whose Materia Medica is, for the greater part, derived from the Vegetable Kingdom. In order, therefore, to invite attention to the science of Botany, as well as to assist the prac- titioner in the Botanical investigation of the various Medicinal Plants referred to in the body of this work, a departure from the usual course pursued in the preparation of Dispensatories has been taken, and as full a description of their Natural Orders, as could be obtained from the various authors consulted, given in the following pages. These, together with the individual characters related under the head of each article of the Materia Medica, Part II, will enable the Practitioner to select with accuracy, our various indigenous Medicinal Plants, from those not yet recognized as such. This will, undoubtedly, be viewed as a most import- ant acquisition to the work, one which must materially enhance its value, in a practical sense, when it is remembered, that for want of a reference of this kind, many efficacious Remedial Plants, have remained unnoticed, or been entirely forgotten. Botanists have divided the Vegetable Kingdom into two great natural divisions, viz; 1. Ph^enogamous or Flowering Plants, which are also called Vasctjlares, from their abounding with ligneous and vascular tissue ; 2. Cryptogamia or Flowerless Plants, also called Cellulares from consisting chiefly of cellular tissue. These have again been divi- ded into Orders, Classes, Genus, Species, etc., to enter into a detail of which is out of the province of this work. 12 Natural Orders of Plants.

ORDER CXVI. Musci or Bryace^e. Moss. Erect or creeping, terrestrial or aquatic, cellular plants, having a distinct axis of growth, destitute of a vascular system and covered with minute, sessile, imbricated, entire, or seriated leaves, producing spore- cases which open by a terminal lid, and contain simple spores alone. Reproductive organs of two kinds: 1. The sterile flower consisting of from four to twenty or more minute cylindrical or fusiform stalked sacs, (anlheridia) which discharge from their apex, upon the application of water, a mucous fluid filled with oval particles, and then perish. 2. The fertile flower composed of from four to twenty or more flask-like bodies (pistillidia), each having a membranous covering (calyptra) ter- minated by a long cylindrical funnel-mouthed tube (style). The ripened pistillidium (seldom more than one in a flower maturing) becomes the capsule, which is rarely indehiscent, or splitting by four longitudinal slits, but usually opens by a lid (operculum) ; beneath the operculum and arising from the mouth of the capsule, are commonally either one or two rows of rigid processes (collectively, the peristome), which are always some multiple of four ; those of the outer row are called teeth, of the inner cilia. An elastic ring of cells (annulus) lies between the rim of the capsule and operculum. The powdery particles filling the capsule are spores. The thread-like stalk (pedicel) supporting the capsule is inserted into the elongated torus (vaginula) of the flower. - The pedicel continued through the capsule, (or hollow urn-like case) forms the columella ; enlarged under the capsule it sometimes forms an apophysis. The calyptra separating early at its base is carried up on the apex of the capsule ; if it splits on one side it is hoodshaped or cuculliform, if not, it is mitre-shaped or mitriform. Intermixed with the reproductive organs are cellular jointed filaments (paraphyses). The leayes surrounding the antheridia are called the perigonial leaves, those around the pisiillidia or pedicel the perichwtial leaves. Polytrichum. Calyptra densely hairy. Capsule four to six-sided, with a discoidal apophysis. Peristome single, of sixty-four teeth, ad- Natural Orders of Plants. 137 herentby their summits to the membranous-dilated apex of the columella.

Cells long and tubular, or round and short, or polygonal, sometimes arranged in a single row ; sometimes disposed in several parallel rows, forming an articulated frond, or if of unequal lengths, forming a cellular frond. Their propaga- tion is by spores (sphaerospores and tetraspores) collected in fours or threes within a transparent perispore, in bodies of different forms and structure. 1. Fucus. Frond plane compressed or cylindrical, linear, dichoto- mous, coriaceous. Air-vessels when present, innate in the frond, simple, large.

Frond horny or cartilaginous, filiform, cylindrical, irrefrularlv branched. Fructification uniform ; spherical sessile capsules containing a globose mass of seeds. ORDER CXVIII. Lichenace^e. Lichen. Perennial plants, often spreading over the surface of the earth, on rocks or trees in dry places, in the form of a lobed and foliaceous, or hard and crustaceous, or leprous substance called a thallus. This thallus is formed of a cortical and medullary layer, of which the former is simply cellular, the latter both cellular and filamentous ; in the crus- taceous species the cortical and medullary layer differ chiefly in texture, and in the former being colored, the latter colorless ; but in the fruticu- lose or foliaceous species, the medulla is distinctly floccose, in the latter occupying the lower half of the thallus, in the former inclosed all round by the cortical layer. Reproductive matter of two kinds: 1, sporules lying in membranous tubes (thecce) immersed in nuclei of the medullary substance, which burst through the cortical layer, and color and harden by exposure to the air in the form of little disks called shields; 2, the separated cellules of the medullary layer of the thallus. 1. Cetraria. Thallus foliaceous, cartilagino-membranaceous, ascend- ing and spreading, lobed and laciniated, smooth and naked on each side. 138 Natural Orders of Plants. Shields orbicular, obliquely adnate with the margin of the thallus, the lower portion being free, (not united with the thallus); the disk colored, plano-concave, with a border formed of the thallus and inflexed. ORDER CXIX. Fungace^e. Mushroom. Plants consisting of a congeries of cellules, among which filaments are occasionally intermixed, increasing in size by addition to their in- side, their outside undergoing no change after its first formation, chiefly growing upon decayed substances, frequently ephemeral, and variously colored. Sporules lying either loose among the tissue, or inclosed in membranous cases called sporidia. Agaricus, Boletus, and Spermcedia, belong to this order. SEXUAL OR ARTIFICIAL SYSTEM OF LINN^US. As the Sexual System of Linnaeus is still followed by many, and espe- cially by those who are commencing the study of Botany, the following brief sketch of it is here introduced, as an aid to the Physician in determining medicinal plants, herein described. At the present day, the eleventh, eighteenth, and twenty-third classes of the following table, have usually been omitted, and distributed among the other classes. CLASSES. Based upon the number or variations and modifications of the Stamens. 1. Monandria ; one stamen to each flower. 2. Diandria ; two stamens do. 3. Triandria ; three stamens do. 4. Tetrandria ; four stamens do. 5. Pentandria ; five stamens do. 6. Hexandria ; six stamens do. 7. Heptandria ; seven stamens do. 8. Octandria ; eight stamens do. 9. Enneandria ; nine stamens do. 10.

Polygamia ; stamens and pistils, in the same or separate flowers, and on the same or on different plants; varying. 24. Cryptogamia ; stamens and pistils wanting or invisible. ORDERS. Founded upon the modifications of various parts of the flowers, as the Styles, or where these are wanting, the Stigmas, also the Seeds, Pods, etc. 1. Monogynia ; includes all the genera of plants in either of the first thirteen classes, with one style or stigma to the flower. 2. Digynia; do. with two styles or stigmas. 3.

Angiospermia ; with seeds in a seed-vessel, or pericarp. The fifteenth class has also two orders, viz : Siliculosa ; the fruit a silicle or short pod. Siliquosa ; the fruit a silique or long pod. The sixteenth, seventeenth, eighteenth, twentieth, twenty-first, and twenty-second classes, have their orders founded on the number of sta- mens to the flower, the order bearing the name of the first thirteen classes; thus the sixteenth class flower with three stamens would be named Monadelphia Triandria, etc. 140 Natural Orders of Plants. The nineteenth class has its orders founded upon the character of its flowers, thus : Polygamia .equalis ; flowers in heads, and all perfect. Polygamia superflua ; florets of the rays, or margin of the head pistillate ; the rest perfect. Polygamia frustranea ; florets of the margin neutral, the rest perfect. Polygamia necessaria ; florets of the margin pistillate and fertile, the rest or disk-flowers staminate and sterile. Polygamia segregata ; each flower having its own proper calyx or involucre. Monogamia ; flowers solitary, but with united anthers. The twenty-third class has its orders founded on the characters of the two preceding classes, thus ;— Monoscia ; where both separated and perfect flowers are found on the same plant. Dicecia ; where the different flowers are found on different plants. Trkecia ; where perfect flowers are found on one plant, staminate on another, and pistillate on still another. The twenty-fourth class has its orders, based upon the natural cha- racter of the plants ; they are :— Filices; ferns. Musci ; Mosses. Hepatic^e ; liverworts. Alg/e ; seaweeds. Lichenes ; lichens. Fungi ; mushrooms or toad-stools. PART II. MATERIA MEDICA. ABELMOSCHUS ESCULENTUS. Okra. Nat. Ord.—Malvacese. Sex. Syst.—Monadelphia Polyandria. FRUIT. Description. This is an Annual plant, known also by the name of Gombo, and is the Hibiscus Esculentus of some authors. The stems are somewhat woody toward the base, erect, branched, round, from three to six feet in hight, and three or four inches in diameter. The herbaceous part is covered with sharp bristles, and often bears purplish spots. The leaves are alternate, petioled; the lower ones being angular, the central ones palmate, and the upper ones subdigitate, the divisions being lan- ceolate-oblong; all are serrate and somewhat bristly. The petioles are round, bristly, and as long as the leaves. The flowers are very large, axillary, solitary, on short peduncles, of a pale-yellow color, with a dark- crimson bottom. Involucre one, from six to twelve-leaved ; leaflets linear, bristly, deciduous. The calyx spathiform, of a very soft texture, burst- ing lengthwise on one side ; stigmas equal to the cells in the capsule. Capsule six to twelve inches in length, about one inch in diameter, some- what bristly, especially the ridges, equal in number to the cells and valves, with a single row of round, smooth seeds in each cell. History. This plant is a native of the West Indies, and is also culti- vated in the Southern States, where the capsule is much employed in soups, and for pickles. The capsule is the part employed, and abounds in mucilage. The Hibiscus Abelmoschus, or Abelmoschus moschatus, a foreign evergreen shrub, grows in various parts of the world, in Egypt, the East and West Indies, etc., and affords the seeds known under the names of Semen Abelmoschi, alceae ^Egypticae, and grana moschata. These are about the size of flaxseed, reniform, striated, of a grayish- CHI) 142 Materia Medica. brown color, a musk odor, and a warm rather spicy taste, and are used by the Arabs to flavor their coffee. Properties and Uses.—Qk™ is mucilaginous, and may be employed wherever emollients and demulcents are indicated ; the leaves are occa- sionally employed for preparing emollient poultices. The seeds of the foreign plant were formerly considered stimulant and antispasmodic ; but are at present only used in perfumery. ABIES BALSAMEA. Balm of Gilead. Nat. Ord.—Pinacese. Sex. Syst.—Moncecia Monadelphia. JUICE, OR RESINOUS EXUDATION. Description.—This is an elegant tree, rising from twenty to forty feet in bight, and of a pyramidal form. It is also known by the name of American Silver Fir. The leaves are from six to eight lines in length, solitary, flat, either acute or emarginate, entire, glaucous, silvery-white beneath, and on their upper surface, glaucous, shining, dark-green ; somewhat pectinate, suberect above, sometimes curved to one side, and spreading more or less perfectly in two rows on the sides and tops of the branches. The male flowers are yellow, numerous, axillary, solitary, and about as long as the leaves ; the female catkins are lateral, cylin- drical, erect, and green ; the bracts abbreviate, obovate, mucronate, and subserrulate. The cones are large, cylindrical, erect, of a purplish color, and covered with a resinous exudation, which gives them a glossy, rich and elegant appearance. History.—This tree inhabits Canada, Nova-Scotia, Maine, and moun- tainous regions further to the South. It furnishes the Canada Balsam, also called Balsam of Fir, or Canada Turpentine. The vesicles which naturally form upon the trunk and branches are broken, and their liquid contents received into a bottle. Canada Balsam is a transparent fluid, or nearly so, colorless, or of a pale-yellow tint, tenacious, of the consistence of thin hone}', of a strong, agreeable, terebinthine odor, of a slightly bitter and not very acrid taste, and very slow to consolidate. On exposure to the air, it gradually becomes concrete, owing partly to the escape of volatile oil, and partly to its conversion into resin. A moderate heat renders it completely liquid; a higher heat gives off volatile oil, leaving behind resin some- what empyreumatised. The same result takes place when boiled with water, and the remaining unevaporated water holds a little succinic acid in solution. It is readily inflammable, burning with a dense reddish flame, and much black smoke. It is partially soluble in alcohol; and a part of its resin forms a soluble soap with solution of potassa. It has not Abies Canadensis. 143 been satisfactorily analyzed. Bonastre obtained from 100 parts, 18.6 of volatile oil, 40.0 of resin soluble in alcohol, 33.4 of sub-resin, nearly insoluble in alcohol, 4.0 of caoutchouc, 4.9 of bitter extractive and salts, and traces of acetic acid. Its therapeutical influence upon the system is owing to its essential oil. The name balsam is improperly applied to it, as it consists chiefly of resin and essential oil, and contains no cinnamic acid, nor benzoin. Properties and Uses.—Canada Balsam is stimulant, diuretic, anthel- mintic, and in large doses, cathartic ; it acts more especially on the mucous tissues of the system, and if its use be continued too long, or in too large doses, it will irritate these tissues more or less, especially those of the urinary organs, producing strangury; if, however, it should act as a laxative, this irritation is not apt to follow. It has been advanta- geously employed internally in gonorrhea, gleet, leucorrhea, piles, chronic urinary difficulties, chronic inflammations or ulcerations of the bowels, chronic catarrhal affections, and rheumatism. In gonorrhea, where the use of copaiba is not desirable, I have found the Canada Balsam an excellent substitute in the following combination, viz: Take of Canada Balsam two fluidounces, Oil of Turpentine four fluidrachms, Spirits of Nitric Ether eight fluidounces, Pulverized Camphor, two drachms ; mix these together. The dose is a fluidrachm three times a day. In cases where the inflammatory symptoms have been subdued, pulverized Kino, two drachms, may also be added. Externally, Canada Balsam acts as a rubefacient, and is frequently employed as a stimulant to wounds and ulcers ; it likewise enters into the composition of several salves and irritating plasters. Dose, from ten to twenty grains two or three times a day, in pills or in emulsion. ABIES CANADENSIS. Hemlock Spruce. Nat. Ord.—Pinaceas. Sex. Syst.—Moncecia Monadelphia. THE PREPARED CONCRETE JUICE, CANADA PITCH, GUM HEMLOCK. Description.—This tree sometimes attains the bight of eighty feet, with a trunk two or three feet in diameter. The leaves are very numerous, about half an inch in length, linear, flat, obtuse, denticulate, and irregu- larly arranged in two rows. The cones or strobiles, are oval, of few scales, pendulous, about three-quarters of an inch long, and terminal or at the ends of the branches. History.—The foliage of this tree is delicate, bright green above, and silvery-white underneath. Hemlock Spruce is abundant in Canada, Nova Scotia, and the elevated and mountainous regions of New England and the Middle States. Its timber is very coarse-grained, and its bark contains an 144 Materia Medica. astringent principle, and is much used for tanning purposes. The pitch or juice exudes spontaneously, and hardens upon the bark, from which it is obtained by boiling fragments of the bark thus incrusted, in water, and skimming off the pitch which rises to the surface. A second boiling still further purifies it. Canada Pitch is hard, brittle, quite opake, of a dark yellowish brown color, which becomes still darker by exposure to the air; of a weak, peculiar odor, and scarcely any taste. It softens and becomes adhesive with a moderate heat, and melts at 198° F. It consists of resin, and a small portion of essential oil. Properties and Uses.—Gum Hemlock is a gentle rubefacient, and is sometimes employed for the same purposes as Burgundy pitch, which it resembles in its properties. The tincture of the hemlock pitch is diuretic and stimulant. The volatile oil, oil of hemlock, has been used to produce abortion, but it is dangerous. As a liniment, this oil has been used in croup, rheumatism, and other affections requiring a stimu- lating local application. The essence of hemlock is diuretic and stimu- lant; Dr. W. K. Everson states it to be a superior remedy in gastric irritation, to allay vomiting in cholera-morbus, etc.; the dose is five or ten drops in water, every ten or twenty minutes, until relief is afforded. I have found the following preparation very beneficial as an internal agent, in rheumatism, colic, flatulency, acid-stomach, pains or soreness of the chest or stomach, languor, depression of spirits, hysterics, pyro- sis, and many other chronic and painful affections. Take of Balsam Tolu, Gum Guaiacum, Gum Hemlock, Gum Myrrh, of each, coarsely powdered, two ounces, Oil of Hemlock three ounces, Oil of Wintergreen two ounces, Alcohol one gallon. Mix and allow them to macerate for two weeks, frequently agitating. The dose is a lluidrachm in half a wine- glass of sweetened water; or in severe cases, it may be increased to half an ounce. I have employed this preparation for several years, and can confidently recommend it to the profession as an effectual agent in the above disorders. A strong decoction of the bark of this tree is beneficial in leucorrhea, prolapsus-uteri, diarrhea, etc., administered in- ternally, and used in enema; it is likewise of service, as a local applica- tion, in gangrene.

Description.—This tree, also called Norway Spruce Fir, has a trunk from three to five feet in diameter, and sometimes attains the hight of Abies Excelsa. 145 one hundred and fifty feet. The leaves are short, obscurely four-cornered, often curved, of a dusky green color, shining on the upper surface, and stand thickly upon the branches. The male catkins are purple, axil- lary, and solitary, scales staminiferous at the apex ; the female catkins are usually purple, terminal, and simple; ovaries two; stigmas glandular; cones, with imbricated scales, which are thin at the apex, and rounded, pendent and purple. History.—The Norway Pine is a native of Europe and Northern Asia; and, as well as the Abies Picea, or European silver fir-tree, furnishes the Burgundy pitch of commerce. The pitch is obtained by allowing the turpentine, which flows from incisions, to harden on the bark, and then purifying it by melting it in water, and passing it through a cloth. Pure Burgundy pitch is hard, brittle, quite opake, of a yellowish or brownish color, and a sweet, perfumed, weak, terebinthinate taste, without bitterness, and a strong, peculiar, balsamic odor. It is very fusible, and at the heat of the body softens and becomes adhesive. It contains a minute proportion of essential oil. As brought to this country, it is generally mixed with impurities ; the true pitch is seldom met with, spurious sorts being substituted, made by melting together pitch, resin, and turpentine, and agitating the mixture with water. The spurious kind may be known by their different odor, their bright yellow color, their numerous vesicles, and by the aqueous vapor they yield when heated. The resinous exudation from this tree, in the form of concrete tears, is the Thus or Frankincense of commerce, or Abietis Resina. Frankincense is in solid, brittle tears, externally brownish-yellow, paler internally, and emitting an agreeable odor when burned ; at the temper- ature of the body, it softens and becomes adhesive. It is used only as an ingredient in plasters. Properties and Uses.—A gentle rubefacient, similar to the Canada pitch. It is applied externally in form of a plaster, and produces a slight degree of inflammation and serous effusion, without separating the cuticle. Sometimes it excites a papillary or vesicular eruption, and has been known to create excessive pain, tumefaction, and redness, fol- lowed by vesication and even ulceration. Used chiefly in chronic rheu- matic pains, and chronic affections of the chest or abdominal viscera. It enters into several salves and plasters. Off. Prep.—Emplastrum Picis Compositum ; Emplast.

Syst.— Moncecia Monadelphia. resinous exudation. Venice turpentine. (See Oleum Terebinthinai.) Description.—The Larch is a tree of straight and lofty growth, with wide-spreading branches, whose extremities droop in the most graceful manner. The buds are alternate, perennial, cup-shaped, scaly, pro- ducing annually a pencil-like tuft of very numerous, spreading, linear, bluntish, entire, smooth, tender, bright-green, deciduous leaves, about an inch long. Male flowers, drooping, about half an inch long, yellow; female catkins, erect, larger than the male flowers, and variegated with green and pink; cones, erect, ovate, about an inch long, purple when youno-, reddish-brown when ripe, their scales spreading, orbicular, slightly reflexed, and cracked at the margin. It is a native of the mountainous regions of the north and middle of Europe. History.—The trunk of the tree furnishes Venice Turpentine ; and a peculiar saccharine substance exudes from the branches, called Manna of Briancon. When the larch forests in Russia take fire, a gum issues from the trees during their combustion, which is termed "Gum Orenberg," and which is wholly soluble in water like Gum Arabic. Genuine Venice Turpentine is a viscid liquid, of the consistence of honey, of a yellowish or slightly-greenish color, and imperfectly trans- parent ; it flows with difficulty, has a strong, not disagreeable odor, and a warm, bitterish, and very acrid taste. It is wholly soluble in alcohol. The factitious Venice turpentine is of a brownish color, and is made by dissolving resin in oil of turpentine. Properties and Uses.—(See Oil of Turpentine.) Off.

Description.—This tree grows in the northern parts of this continent, and in elevated situations in the Middle States. It attains the hight of from forty to seventy feet, having very dark-green leaves, short, erect, rigid, and the cones one or two inches long, reddish-brown, ovate and their scales wavy and toothed at the apex. Abies Nigra — Abies Picea. 147 Properties.—The extract or Essence of Spruce is made from the young branches, by boiling them in water, straining and evaporating. From this Spruce Beer is made ; an agreeable and not unwholesome summer drink. It is made as follows : Take of essence of spruce half a pint, bruised ginger, pimento, and hops, of each, four ounces, water three gal- lons. Boil for ten or fifteen minutes, then strain, add of warm water, eleven gallons, molasses, six pints, and yeast, a pint; mix, and allow the mixture to ferment for twenty-four hours. ABIES PICEA. Silver Pine. Nat. Ord.—Pinaceae. Sex. Syst.—Monoecia Monadelphia. STRASBURGH TURPENTINE. Description.—This tree, also known as Silver Fir, grows in the moun- tains of south and central Europe, and resembles the Abies Balsamea, but differs in not having its bracts so sharp pointed, its cones less acute at each end, and the crest of its anthers pointed. It affords the "Stras- burgh Turpentine." Properties and Uses.—(See Oil of Turpentine.) ACACIA ARABIC A. (Acacia Vera.) Acacia. Nat. Ord.—Fabaceas, or Leguminosae. Tribe.—Mimoseas. Sex. Syst.—Poly- gamia Moncecia. THE CONCRETE JUICE. GUM ARABIC. Description.—Acacia Arabica, also known by the name of Egyptian Thorn, or Egyptian Gum Arabic is a small tree or shrub, but which sometimes attains the hight of forty feet, with a trunk from twelve to sixteen inches in diameter. The leaves are alternate and doubly pinnate, with four or six pairs of pinnae, each being composed of from ten to twenty pairs of minute, smooth, oblong, linear leaflets, with a gland on the common petiole, below the first, and generally one between the last pair of pinnae. Spines straight and in pairs. Flowers yellow, in globose, pedunculated, axillary, subternate heads. The Legume is moniliform. Acacia Vera is a tree of middling size, with a crooked stem covered with a smooth gray bark, numerous scattered branches covered with a yellowish-green or purplish bark. The leaves are alternate, bipinnate, 148 Materia Medica. and composed of two pairs of opposite pinnae, with numerous, small, oblong, linear, and smooth leaflets, supported on very short footstalks ; on the common petiole, and between each pair of pinnae, is a gland. The flowers are bright yellow, inodorous, small, and collected in globular heads about two together, and supported on slender, axillary peduncles, and furnished with two small bracts. The branches and petioles are glabrous ; the spines are in pairs, sharp, and from three to six lines long, and are situated at the insertion of each leaf, being united at their base. The legume is four or five inches long, moniliform, smooth, flat, of a pale- brown color, and divided into several orbicular portions, in each of which is contained a single, flattish seed. The best quality of Gum Arabic is obtained from this tree. History.—These trees grow in upper and lower Egypt, Senegal, and other parts of Africa, also flourish in Arabia, and in Hindostan, where their gum is used for food by the natives. The A. Arabica is the most widely diffused of the gum-bearing trees. Gum Arabic is likewise obtained from several other species of Acacia, but not so largely as from the two above-named. The gum of the Acacias exudes spontaneously from the bark of the trunk and branches, and hardens on exposure ; but incisions are sometimes made in order to facilitate the exudation. It exudes from the trees in the form of a thick and somewhat frothy juice, soon after the rainy season has softened their bark, and rendered it apt to split during the hot weather that succeeds. It is secreted in greatest abundance by old stunted trees, and in dry, hot seasons, and is thought by some to be the result of disease. The best quality of Gum Arabic has a very pale, straw color, breaks with a vitreous fracture, is transparent, inodorous, insipid, and feels quite viscid in the mouth. It is generally in small, round, irregular lumps, of easy fracture. Its colored varieties are bleached by exposure to the light of the sun. Its specific gravity varies from 1.3 to 1.4. In powder it is always white. Gum Arabic is soluble in cold or hot water, forming a viscid solu- tion called mucilage, which, when evaporated, yields the gum unchanged. It is insoluble in alcohol, ether, and the oils, and is precipitated from its aqueous solution by alcohol. Concentrated acids decompose it. A soliuion of borax coagulates it. It unites with sugar in solution, which when evaporated yields an uncrystallizable, transparent, solid substance. It is also soluble in dilute acids, solutions of the pure alkalies, and lime- water. A concentrated aqueous solution of Gum Arabic may be kept a long while, unless the weather be very hot, in which event it will ferment. A weak solution ferments speedily, and acetous acid is developed. Nitric acid changes pure gum into mucic or saccho-lactic acid. Analysis shows it to contain bi-malate, and muriate of lime, muriate and acetate of potassa, and some other matters. Acacia Catechu. 149 Properties and Uses.—Nutritive and demulcent. Used in irritations or inflammations of mucous surfaces; as, hoarseness, sore-throat, cough, gonorrhea, catarrh of the urinary bladder, dysentery, diarrhea, stran- gury, and tenesmus. It may be given, ad libitum, in the form of solution or lozenge; as an article of diet in cases requiring a rigid regimen, as in fevers, it is superior to any other substance; it maybe used for this purpose by. dissolving the gum in powder, half an ounce, in five ounces of water, and sweetening with loaf-sugar, of which a tablespoonful may be given every two or three hours ; in low stages of fever, in typhoid fever, and wherever a mild stimulant is required, one ounce of a satu- rated solution of camphor in sulphuric ether may be added to the above, and administered in the same way ; it is diuretic, promotes the action of the absorbents, and does not materially increase arterial action. Equal parts of pulverized alum and Gum Arabic form a good preparation to check hemorrhages from small cuts, wounds, etc. Externally, the application of its solution to burns and scalds has proved serviceable, repeating it until a complete coating is secured. It is likewise much used for compounding pills, lozenges, mixtures and emulsions ; also for administering insoluble substances in water, as oils, resins, balsams, camphor, musk, etc. Mucilage of Gum Arabic—To four ounces of finely pulverized Gum Arabic, add, very gradually, a pint of boiling water, and rub the whole until perfectly blended. Dose, ad libitum. When Gum Arabic is adulterated with cherry gum, it is not easy to form a good mucilage ; the cerasin of the cherry gum will cause it to be ropy. ACACIA CATECHU. Catechu. (Cutch. Gambeer. Terra Japonica.) Nat. Ord.—Fabaceas, or Leguminosaa. Tribe.—Mimosese. Sex. Syst.—Poly- gamia Moncecia. EXTRACT OF THE WOOD. Description.—The Acacia Catechu is a small tree, seldom more than twelve feet high, and with a trunk one foot in diameter. The bark of the tree is thick, scabrous, ferruginous, red within, very astringent and somewhat bitter. The branches are spreading and irregular, and when young, pubescent; the older ones have many stipular prickles, in pairs and recurved. The leaves are alternate, and consist of ten to thirty pairs of pinnae about two inches long, each having many small, linear leaflets, covered with short hairs, and of a pale-green color. At the base of each pair of pinnae is a small gland upon the common petiole, and attached to the stem at the base of each leaf, are two short, recurved spines. The flowers are numerous, axillary, in slender cylindrical spikes, 150 Materia Medica. about four or five inches long, and of a pale-yellow color. The calyx tubular, hairy, and five-toothed. The corolla is composed of five petals, united into a tube at the base, and is longer than the calyx. Stamens numerous, distinct, with roundish anthers. The ovary is green, oval, glabrous, supporting a slender style, and terminated by a simple stigma. The legume is lanceolate, flat, straight, smooth, and brown, with an undulated thin margin, containing six or eight roundish, flattened seeds, which emit a nauseous odor when chewed. History.—This species of Acacia is a native of the East Indies, grow- ing abundantly in Hindostan and in the Burman empire. The officinal catechu is prepared by boiling the leaves or wood in water, then evapo- rating to the proper consistence, and pouring into quadrangular earthen molds. Catechu is likewise obtained from the Areca Catechu and Unca- ria Gambir. There are several kinds of it met with in commerce, but the best is that which possesses the most astringency, and which can be determined by the taste. Catechu varies in its color and appearance, being from pale to a dark- brown, in square, round, and irregular pieces, friable, specific gravity 1.2 to 1.3, inodorous, astringent, and succeeded by an agreeable sweet taste. That which is preferred is of a dark color, easily broken into small angular fragments, with a smooth, glossy surface, bearing some resemblance to Kino. It is soluble in hot water, which deposits a red- dish matter on cooling. Cold water partially dissolves it. Alcohol or proof spirit dissolves it readily. It contains tannin, extractive, and mu- cilage. Ether dissolves its tannin and catechuic acids. The dark- colored catechu is the most astringent. It is incompatible with solutions of the pure earths, with sulphuric acid or muriatic acids, salts of alumina, lead, copper, and of the sesquioxide of iron, also with gelatin, opium, cinchona, and those salts of the veget- able alkaloids, which form insoluble salts with tannin. Properties and Uses.—Catechu is a pure and powerful astringent, and slightly tonic. It is used for arresting mucous discharges when exces- sive, for removing relaxation or congestion of mucous membranes, and for checking hemorrhages. In chronic diarrhea, chronic catarrh, colli- quative diarrhea, and chronic dysentery, it has proved beneficial espe- cially when combined with opium. As a local application it is a valuable agent for removing cynanche tonsillaris, aphthous ulcerations of the mouth, elongation of the uvula, and relaxation and congestion of the mucous membrane of the fauces, especially of the kind to which public singers are subject; it is also useful in congestion, tenderness and spongi- ness of the gums, particularly when the result of mercurial ptyalism. The tincture of catechu is often useful in fissure of the nipples, when applied twice a day with a fine hair pencil. Catechu is likewise benefi- cial as a topical application to ulcers of a phagedenic character, and to indolent ulcers. An infusion of catechu may be used as an injection in Acacia Catechu — Acetum. 151 obstinate gonorrhea, gleet, and leucorrhea; and thrown up the nostrils is beneficial in epistaxis. The dose of powdered catechu is from ten to thirty grains, frequently repeated, and is best given with sugar, gum arabic, and water ; dose of the tincture from one drachm to half a fluid- ounce. ACETUM. Vinegar. IMPURE DILUTE ACETIC ACID, PREPARED BY FERMENTATION OF CIDER, MALT, OR WINE. Acetum Britannicum.—Common British made Vinegar, from infusion of malt. Density, 1006 to 1019. Acetum Destillatum.—Distilled Vinegar. Acetum Gallicum.—French Vinegar ; density, 1014 to 1022. Acetum Vini.—Wine Vinegar.—Impure Dilute Acetic Acid. History.—Sugar and water, and all saccharine vegetable juices, infu- sion of malt, wine, cider, and all liquors susceptible of vinous fermenta- tion, may be converted into vinegar, by being exposed to a temperature between 75° and 90° F. with access of air, in which they undergo an action called acetous fermentation, and which is developed under a mi- croscopic fungus influence, termed torula aceti. The several changes which occur during this fermentation, are included in the term acetiflca- tion; during the progress of which, heat is disengaged, the liquid becomes turbid, and filaments are formed, which move in numerous directions, and finally, the liquid becomes transparent, with a pultaceous deposit of the filaments, its alcohol has disappeared, and vinegar now occupies its place. This change is supposed to take place, in consequence of the forma- tion of a new substance called Aldehyd, the result of the loss of a part of the oxygen of the alcohol. Alcohol consists of four equivalents of carbon, six of hydrogen, and two of oxygen, through the action of the atmosphere, it loses two equivalents of hydrogen, and becomes aldehyd. This, absorbing two equivalents of oxygen, becomes hydrated acetic acid, consisting of four equivalents each of carbon, hydrogen, and oxy- gen. Aldehyd is an ethereal fluid, very inflammable, colorless, with a pungent taste and smell; its density is 0.79. It absorbs oxygen with avidity. Its name has reference to its character, alcohol dehydroge- nated. Aldehyd resin, a soft, light-brown mass, giving a nauseous soapy smell when heated to 212°, and is formed by decomposing the aqueous solution of aldehyd by eaustic potassa. 152 Materia Medica. Different liquors are employed in the manufacture of vinegar, in dif- ferent countries ; in wine countries, wine is used; in Britain, infusion of malt ; in the United States, cider is principally used. The cider is placed in barrels with their bung-holes open, and which are then exposed to the heat of the sun, during summer, and the acetification is perfected in about two years. This fermentation must be watched during its pro- gress, and as soon as the vinegar is formed, it must be racked off into clean barrels, otherwise it will become spoiled by running into the putre- factive fermentation. Vineoar is also made by various Other methods, many of which require a comparatively short time for its formation. A tumbler full of boil- ing milk added to fifty gallons of vinegar, and stirred into it, will clarify it, without injuring its aroma, and will also render red vinegar pale. Good vinegar is of an agreeable, penetrating odor, and pleasant acid taste; its color varies from pale-yellow to red, and when long kept, it becomes turbid and ropy, putrefies, becomes fetid, and loses its acidity, more especially if exposed to the air. Malt vinegar is usually of a yel- lowish red color ; containing from 4 to 5 per cent, of acetic acid ; wine vinegar is white or red, according to the wine it is prepared from, and is about one-sixth stronger than malt vinegar. White wine vinegar is pre- ferred to the red, which last may be rendered pale by passing it through animal charcoal. Vinegar may contain sulphuric acid, copper, and lead, which are its most dangerous impurities. The want of action of acetate of lead proves it free from the first; the second may be detected by the addition of ammonia in excess, which renders the acid blue, if copper be pre- sent ; and iodide of potassium will detect lead by throwing down the yellow iodide of lead. Properties and Uses. — Refrigerant, diuretic, astringent, and tonic. Useful in febrile and inflammatory complaints, especially when the tongue is coated dark or brown ; also in typhus and scurvy, as an anti- septic. In urinary affections, attended with a white sediment, consisting mainly of phosphate of lime, and ammoniaco-magnesian phosphate, it has been recommended. In dysentery and scarlatina, vinegar saturated with common house salt, has been very beneficial. A large tablespoon- ful of the mixture must be added to four of hot water, of which a table- spoonful is to be taken, as hot as may be, every two or three minutes, till the whole is consumed. A similar preparation was found very effec- tual in the treatment of Asiatic cholera, in Cincinnati, during 1849-50, and is also asserted to have proved a useful local application in external inflammations, sprains, bruises, swellings, etc. The vapor of vinegar inhaled into the lungs, is useful in diseases of these organs, dryness and irritation of the pulmonary tubes during measles and other exanthema- tous and febrile diseases, also in sore-throat; and diffused through the Achillea Millefolium. 153 rooms of the sick, it is both agreeable and wholesome to the patient and attendants. Vinegar has been used as a gargle, or its vapor inhaled, in putrid sore- throat, ulceration of the fauces, hoarseness, etc.; it has also been applied locally in some cases of ophthalmia, in epistaxis, several cutaneous dis- eases, and, diluted with water, has been used as an injection into the rectum in hemorrhoidal affections, and into the uterus in cases of uterine hemorrhage. It forms a valuable adjuvant to cooling lotions. The dose internally is from one to four fluidrachms ; as an injection, one or two fluidounces diluted with twice or thrice its bulk of water. Distilled Vinegar is used for the same purposes as above, and is the solvent to be employed in making the various medicated vinegars of opium, squill, colchicum, etc. Care must be taken, when using vinegar medicinally, not to obtain the spurious and adulterated articles, contain- ing sulphuric acid, muriatic acid, nitric acid, copper, lead, etc. One part of acetic acid to five of distilled water, forms a very good vinegar, for culinary and medicinal purposes.

ACHILLEA MILLEFOLIUM. Yarrow. Nat. Ord.—Asteraceaa. Sex. Syst.—Syngenesia Superflua. THE herb. Description.—Yarrow, also called Milfoil, is from twelve to eighteen inches high, with simple stems,,branching at top. The leaves are doubly pinnate, crowded, alternate, with linear, dentate, mucronate segments. The flowers are white or rose-cplored, and are arranged in a dense, flat- topped, compound corymb; involucre oblong and imbricated. Rays four or five, short; receptacle chaffy, small, flattish. Achenium oblong, flat- tened, margined. History.—Yarrow is a perennial herb, common to Europe and North America, growing in fields, woods, pastures, etc., and flowering nearly the whole summer. The American plant is the most active. The flowers and leaves have an agreeable, but feeble aromatic odor, and a bitter, astringent, pungent taste. It contains a volatile oil, bitter extrac- tive, tannin, and achilleic acid. The active principles are extracted both by water and alcohol. According to M. Zanon, the active principle of this plant, Achilleine, has been used as a substitute for sulphate of quinia in intermittent 154 Materia Medica. fevers, in the south of Europe. It is prepared by boiling five pounds of the dried plant with sixteen pounds of rain-water for about two hours. The residue is again boiled twice with smaller quantities of water, the decoctions are then filtered and mixed. These are then clarified with white of egg, and evaporated at a gentle heat until a whitish pellicle is formed on the surface. After twenty-four hours the cold liquid deposits a mass consisting for the most part of vegetable fiber, green coloring substance, with some coagulated albumen, extractive matter insoluble in alcohol, lime-salts, and traces of silica. The bitter and acid liquid is filtered, and then treated with an excess of hydrate of lime, which produces a white precipitate; upon this the liquid is treated with acetate of lead as long as any precipitate is formed. This precipitate is collected on a filter, and the solution saturated with sul- phureted hydrogen, after which it still possesses a yellowish color and a very bitter taste. On evaporation it yields nearly half a pound of dry extract, which, as well as the previously-filtered sulphuret of lead, are exhausted with alcohol. The two, mixed and evaporated, yield about seven ounces of achilleine. The achilleine obtained in this manner, contains some acetate of lime, resin, etc., but which may be avoided by treating the neutralized decoc- tion (above, by hydrate of lime) with animal charcoal, then evaporating to dryness, and finally extracting with boiling absolute alcohol. The color of achilleine is instantly destroyed by chlorine; it is not precipitated by tincture of galls nor acetate of lead, but it is thrown down by basic acetate of lead; it is soluble in ammonia, and the solu- tion, when exposed to the air until the ammoniacal odor has disappeared, deposits brown flakes, which are less soluble than achilleine; the slight trace of resin in achilleine may be removed by solution in water. Achilleic acid is obtained by treating the decoction of Yarrow with acetate of lead as long as any precipitate is formed, this is suspended in water, and decomposed with sulphureted hydrogen. The liquid obtained will be very acid, and contain some lime and green coloring substance; to precipitate the lime, supersaturate it with carbonate of potassa, and then treat it with animal charcoal. The potassa-salt may be precipitated with acetate of lead, and the precipitate decomposed with sulphureted hydrogen. Achilleic acid is not volatile at 212° F.; its solution can therefore be concentrated by evaporation in the water-bath. The greatest concentra- tion to which it can be brought is 1.014825. In this state it is perfectly colorless, but on further evaporation it becomes straw-colored. Exposed to the air in a glass or porcelain dish, it crystallizes in perfectly colorless quadrilateral prisms. The crystallized acid requires at 56° F. two parts of cold water for solution; the solution is very acid, makes the teeth rough, has no odor, and strongly reddens litmus paper. Added by drops to a clear solution of acetate of lead, it does not render it in the AciDUM AcETICUM. 155 least turbid; but in a solution of basic acetate of lead it immediately produces a white precipitate, which is very slightly soluble. Achilleic acid forms salts with carbonates of potassa and soda, am- monia, lime, magnesia, and quinia, which may become useful thera- peutical agents. The achilleate of quinia is very soluble, and may be found superior to the sulphate of quinia; it may be made by dissolving quinia in very slightly-diluted acid, allowing the substances to act on each other for several days, stirring them frequently, until the liquid no longer reddens litmus paper. Then filter, and add some alcohol; heat it nearly to boiling, and allow it to cool, when nearly the whole liquid is converted into very beautiful radiate-grouped prismatic crystals, which are very bitter, and readily soluble in water or alcohol. Properties and Uses.—Yarrow is a tonic, astringent, and alterative. It has been used in intermittent fever, hemoptysis, hematuria, incon- tinence of urine, diabetes, hemorrhoids, and dysentery ; also in leucorrhea, amenorrhea, flatulent colic, and some nervous affections. In menorrha- gia, half a fluidounce of the saturated tincture, repeated three or four times daily, has been found advantageous; a few drops of oil of anise will cover its unpleasant taste. The late Prof. T. V. Morrow made much use of an infusion of this herb in dysentery. Dose of the infusion, from four to six fluidounces, three or four times daily; of the volatile oil, from ten to thirty drops. Achillea Ptarmica or Sneezewort, grows in hedges and thickets, and in moist places in various parts of the country. It is about two feet in hight, with the leaves sessile, linear or slightly lanceolate, acuminate, equally and sharply serrate, with appressed teeth, and smooth. The flowers are white, and arranged at the top of the plant in a diffuse corymb. The leaves are remarkably distinct from the Yarrow. The whole plant is pungent, exciting an increased flow of saliva. The powder of the dried leaves when snuffed into the nostrils, produces sneezing, which is supposed to be owing to their small, sharp, and marginal teeth. ACIDUM ACETICUM. Acetic Acid. Preparation.—Take of acetate of soda, in powder, a pound; sulphuric acid half a pound. Pour the sulphuric acid into a glass retort, and gradually add the acetate of soda ; then, by means of a sand-bath, distil the acetic acid with a gentle heat, till the residuum becomes dry. The specific gravity of this acid is 1.0634; and one hundred grains of it saturate 83.5 grains of crystallized bicarbonate of potassa. Chemical Properties.—The acetic acid of the pharmacopoeias is a limpid and colorless liquid, possessing a very sour and acrid taste, and a 156 Materia Medica. fragrant, pungent smell. It unites in all proportions with water, and dissolves to a certain extent in alcohol. It possesses the property of dis- solving a number of substances, such as the volatile oils, camphor, gluten, resins and gum resins, fibrin, albumen, etc. It is incompatible with the alkalies and alkaline earths, both pure and carbonated, with metallic oxides, and most substances acted on by other acids. When well prepared, it should not form a precipitate with the soluble salts of baryta, and should evaporate completely in a glass or platinum capsule, without leaving any residue. The concentrated acid, or radical vinegar, protohydrated acetic acid, is a colorless, volatile liquid at the temperature of 60°, with a strong acid and corrosive taste, and an acid, pungent, and refreshing smell. Its specific gravity is 1.063. It volatilizes without decomposition, and burns with a blue flame when boiled in open vessels ; it attracts humidity from the atmosphere, and should be kept in well-stopped vessels. Properties and Uses.—Acetic Acid is stimulant, rubefacient, vesicant, and escharotic ; and is considerably employed to produce counter-irrita- tion in croup, sore-throat, and other cases of internal inflammation. It may be used by moistening blotting paper or cambric with it, and apply- ing it to the parts to be vesicated. It frequently destroys warts and corns when applied to them, and has been found effectual as an appli- cation to scald-head. In syncope, asphyxia, and headache, its vapor is frequently applied to the nostrils as an excitant. It is only used as an external agent. M. Ricord speaks highly of this acid as a local appli- cation to venereal ulcers in the primary stage, to be applied as freely as any other caustic, and repeated as often as the condition of the chancres may require. Under its influence the ulcer speedily assumes a healthy aspect and promptly heals. He believes that it neutralizes the venereal poison, and thus obviates all danger of constitutional symptoms. We believe the same may be truly said of other acids, as the nitric, muriatic, tincture of chloride, iron, etc. Half a pint of acetic acid, added to five pints of distilled water ; is a valuable substitute for distilled vinegar, in all formulae requiring nicety. Off. Prep.—Linimentum Terebinthinae. ACIDUM ACETICUM EMPYREUMATICUM. ACIDUM PYROLIGNEUM. Pyroligneous Acid. IMPURE ACETIC ACID, OBTAINED FROM WOOD BY DISTILLATION. History.—Pyroligneous acid is a brown, transparent liquid, having a strong, smoky smell. It consists of acetic acid, with more or less water, Acidum Benzoicum. 157 and holding in solution tar and empyreumatic oil. It may be purified by repeated distillation, and then neutralizing it with lime or carbonate of soda. Properties and Uses.—Stimulant and antiseptic. Used as a local application for arresting or preventing sloughing, for cleansing old sores, abscesses, and burns, scalds, ringworm, tinea capitis, excoriated nipples, etc., and as a gargle in inflamed and ulcerated throat, and scarlatina maligna. Internally, in doses of from ten to thirty drops, it is useful in all cases where an antiseptic is indicated. The pyroligneous tar forms a valuable irritating plaster. Hams or beef, salted, and dipped into the crude pyroligneous acid, and then dried, have the smoky flavor imparted to them, as perfectly as if they were smoked by the ordinary process, and are likewise preserved from "skippers." Off. Prep.—Linimentum Terebinthinae. ACIDUM BENZOICUM. Benzoic Acid. Preparation.—Take of coarsely powdered Benzoin, any quantity. Put the benzoin, previously well mixed with an equal weight of fine sand, into a glass vessel, placed in a sand-bath, and with a heat of 300° gra- dually increased, sublime until nothing more ascends. Wrap the sublimed matter in bibulous paper, and press it, that it may be separated from the oily part; then again sublime, with a heat not exceeding 400°. Chemical History.—Benzoic acid is in soft, white, feathery crystals, of a silky luster, and not pulverulent. When pure, it is inodorous, but when prepared by sublimation, it has a peculiar agreeable aromatic odor, which is owing to the presence of an oil. It has a warm, acrid and acidulous taste ; is soluble in alcohol, concentrated nitric and sulphuric acids, solution of potassa, and fixed oils. It is a characteristic consti- tuent of the balsams. Properties and Uses.—Stimulant, and perhaps expectorant. Said by Dr. Ure to convert the uric acid, when in excess, into hippuric acid. Used in the phosphatic form of gravel; also in gout and rheumatism, combined with carbonate of potassa. Used externally in some cutaneous diseases, and enters into some cosmetic washes. Dose, 10 to 30 grains. Off. Prep. — Tinctura Opii Camphorata. Unguentum Sulphuris Compositum. 158 Materia Medica. ACIDUM CHROMICUM. Chromic Acid. Preparation.—To one volume of a cold saturated solution of bichro- mate of potassa add one volume and a half of pure sulphuric acid, and allow the mixture to cool in a covered capsule, or in a flask, when it de- posits beautiful deep-red needles of chromic acid. The liquid being drained off, these are laid on a porous brick to dry, covered with a glass bell-jar. They must be preserved in very tightly-stoppered vials. Chemical Properties.—Chromic Acid is a strong acid, isomorphous with sulphuric, selenic, and manganic acids. It is very soluble in water, and is highly deliquescent in the air. It destroys the color of indigo, and of most vegetable and animal coloring matters. It is a powerful oxidizing agent, yielding half its oxygen readily to oxidizable bodies, and being reduced to sesquioxide. Properties and Uses.—Recommended in the treatment of piles; the acid is to be applied freely over the whole of the diseased surface, and when properly managed it will not spread beyond the prescribed limits. It occasions uneasiness for some hours, and sometimes acute burning pain—a slough passes away, and the tumor shrinks and becomes in- sensible. As soon as its erosive operation is finished, the acid passes into a state of inert pulverulent sesquioxide. It may likewise be found advantageous in cancer, malignant tumors, ulcers, etc. The Bichromate of Potassa in saturated solution has been recommend- ed as a local application to warts, excrescences, and tubercular eleva- tions ; it causes but little pain, and often removes these growths by absorption without any slough; or if a slough has formed, it serves to expedite the cure, and is not followed by deep, unmanageable ulcers. When this salt is applied in solution to the skin, habitually, it first produces an eruption of papulae, which become pustular, and, provided the exposure be continued, form deep sloughs under the pustules, of a peculiarly penetrating character. A green ink may be made by dissolving 180 grains of bichromate of potassa in one fluidounce of water; add to the solution while warm, half a fluidounce of spirit of wine, then decompose the mixture with strong sulphuric acid until it assumes a brown color. Evaporate the liquor to one-half, let it cool, dilute it with two fluidounces of distilled water and filter it, then add half a fluidounce of spirit of wine, and a few drops of strong sulphuric acid, and let it stand. After some time the ink assumes a beautiful green color, and is rendered fit for use by the addition of a small quantity of Gum Arabic. A very cheap ink, costing about two or three cents a gallon, may be made by neutralizing a solution of bichromate of potassa with salt of ACIDUM ClTRICUM --AdDUM GALLICUM. 159 tartar, (or until effervescence ceases). Then add a sufficient quantity of this to an infusion of logwood, to give it the desired color. This ink, however, is apt to fade, and precipitates from the slightest causes; the smallest proportion of common black ink will cause a precipitate. To render the above ink perfectly permanent, and of a more intense black color, add to it a few drops of a solution of corrosive sublimate. ACIDUM ClTRICUM. Citric Acid. Preparation.—Citric Acid is present in the juices of many fruits, but it is principally obtained from lemon or lime-juice, which is saturated with prepared chalk, the precipitated citrate of lime is repeatedly washed, and then decomposed with a slight excess of dilute sulphuric acid ; then strained, carefully concentrated by boiling, and crystallized. Chemical Properties.—Citric acid is a white crystallized solid, often in large crystals, having the form of rhomboidal prisms with dihedral sum- mits. It is permanent in dry air. Specific gravity, 1.6. Its taste is strongly acid, and almost caustic. It dissolves in three-fourths of its weight of cold, and half its weight of boiling water. A weak solution has an agreeable taste, but soon undergoes spontaneous decomposition. It is also soluble in alcohol. Properties and Uses.—Citric acid is refrigerant and antiscorbutic. It may be used in fevers, in the form of lemonade, made by dissolving the acid in water, sweetening sufficiently, and adding a few drops of essence of lemon ; it is likewise beneficial in scurvy, acidity of the stomach, and some peculiar forms of sick-headache. A mixture for making good lemonade, and which will keep for years if preserved dry, is to combine together, one and a half ounces of powdered citric acid, one pound of powdered white sugar, and five drops of oil of lemon. A teaspoonful of this to a pint of water, forms an agreeable and beneficial draught for patients with febrile diseases, especially when the tongue is coated brown or black. ACIDUM GALLICUM. Gallic Acid. Preparation. — Take of Galls in powder, three pounds; distilled water, purified animal charcoal, of each a sufficient quantity. Mix the galls with sufficient distilled water to form a thin paste, and expose the mixture to the air, in a shallow glass or porcelain vessel, in a warm 160 Materia Medica. place, for a month, occasionally stirring it with a glass rod, and adding from time to time sufficient distilled water to preserve the semi-fluid consistence. Then submit the paste to expression, and rejecting the expressed liquor, boil the residue in a gallon of distilled water for a few minutes, and filter while hot through animal charcoal. Set the hot liquor aside that crystals may form, which may be dried on bibulous paper. If the crystals be not sufficiently free from color, they may be purified by dissolving them in boiling distilled water, filtering through a fresh portion of animal charcoal, and crystallizing. This is the process recommended by the U. S. Pharmacopoeia, and is based upon the fact, that galls in decoction or moistened, and exposed to the air, gradually have their tannic acid converted into gallic acid, oxyo-en being absorbed, with the escape of an equivalent amount of carbonic acid. The smallest quantity of sesquioxide of iron, will pre- vent the bleaching of the acid, so that the animal charcoal should be purified, and the filtering-paper examined. As the first crop of crystals obtained by the above method, retains a large quantity of water, they should be subjected to strong expression between two folds of bibulous paper. Mr. C. Wetherill, upon the belief that gallic acid differs from tannic, wholly in containing water, endeavored to prepare the former from the latter, by the fixation of the water, and succeeded by means of sulphuric acid. He mixed thirteen drachms of tannic acid with twenty-two fluid ounces of sulphuric acid and four times that bulk of water, and heated the mixture to the boiling point, and then allowed it to stand. In a few days an abundant precipitate of white gallic acid took place, amount- ing to 87.4 per cent, of the tannic acid. History.—Gallic acid is in delicate, silky, acicular crystals, slightly brownish, but colorless when pure. It is inodorous, and of a sourish astringent taste. It is soluble in 100 parts of cold water, and 3 of boil- ing water, very soluble in alcohol, and only slightly so in ether. On exposure to the air it undergoes spontaneous decomposition. Heated to 420°, it gives out carbonic acid, and is converted into pyro-gallic acid; thrown on red-hot iron, it is entirely dissipated. It does not precipitate gelatin like tannic acid, nor a solution of sulphate of protoxide of iron, but occasions a deep bluish-black precipitate with a solution of the salts of sesquioxide of iron. Its formula is CT H3 05, and its combining number 85. Properties and Uses.—Gallic acid is a valuable astringent, and is used principally as an internal astringent. As such it has been found benefi- cial in hemorrhages from the kidneys, uterus, and lungs. Menorrhagia has promptly ceased under its use. It is also useful in chronic mucous discharges from the bowels or bladder, and has some reputation in arresting the excretion of albumen in Bright's disease of the Kidney. Acidum Hydriodicum — Acidum Hydrochloricum. 161 It is believed to be more efficient than tannic acid, in cases of hemor- rhage, where the bleeding vessels must be reached through the circula- tion, as its chemical affinities do not afford the same impediment to its absorption as those of the tannic acid. It is said not to constipate. Dose of gallic acid, is from five to fifteen grains, three or four times a day, in the form of pill or powder. Off. Prep.—Liquor Potassae Citratis ; Ferri et Quiniae Citras; Ferri Citras; Quiaiae Citras. ACIDUM HYDRIODICUM. Hydriodic Acid. Preparation.—Take of iodide of potassium 330 grains, tartaric acid 264 grains. Dissolve these salts, separately, each in a fluidounce and a naif of distilled water, and mix the solutions. Filter the liquor, in order to separate the bitartrate of potassa which precipitates, and add to it sufficient distilled water to make the whole measure fifty fluidrachms. History.—This solution is sufficiently pure for medicinal use, although it contains a little cream of tartar ; each fluidrachm of it contains five grains of iodine. At first it is limpid, or has only a slight yellow tinge, but becomes a wine-yellow on keeping, and finally a beautiful red, in consequence of the disengagement of iodine. Properties and Uses.—Hydriodic Acid is supposed to possess all the virtues of iodine, without any of its irritant properties, and may be em- ployed in all cases where iodine is indicated. The dose is five drops gradually increased to a fluidrachm, and repeated two or three times a day. It should be sufficiently diluted with water, when given, to reduce it to an agreeable acidity. Hydriodic acid has been combined with several of the new organic alkalies, for the purpose of forming new medicinal agents. ACIDUM HYDROCHLORICUM. Muriatic Acid. Spirit of Sea Salt. Preparation.—Hydrochloric Acid is prepared from muriate of soda, by the decomposing power of sulphuric acid, which liberates the acid in the form of gas ; and this passing into vessels containing water, is readily absorbed by that fluid. Chemical Properties.—When pure, hydrochloric acid is a transparent, colorless liquid, of a corrosive taste and suffocating odor. The yellow tinge often seen in the medicinal acid is owing to the presence of iron, or some organic matter. Its specific gravity is 1.21 ; that of the medi- 11 162 Materia Medica. cmal acid is 1.16. It is incompatible with alkalies and most earths, with oxides and their carbonates, and with sulphuret of potassium, tartrate of potassa, tartar emetic, tartarized iron, nitrate of silver, and solution of subacetate of lead. Properties and Uses.—Diluted hydrochloric acid is Ijpnic, refrigerant, and antiseptic. Used in fevers, some forms of syphilis, and to counter- act phosphatic deposits in urine. It has also been beneficial in malignant cases of typhus and scarlatina, given in a strong infusion of quassia. Likewise said to prevent the formation of worms. It is also valuable as a gargle in various ulcers of the mouth and throat, and elongated uvula. The dose is five to twenty drops, in a wineglassful of water; it ought to be sucked through a quill or glass tube, to prevent its injuring the teeth. The dilute acid is made by adding four ounces of pure acid to twelve ounces of water. It is sometimes used, in the concentrated form, as an application to cancrum oris, some obstinate ulcers of the tongue, in certain syphilitic and mercurio-syphilitic diseases, and in phagedenic ulceration ; also, in chilblains or frost-bites. When swallowed internally, in its pure state, magnesia, chalk, or soap dissolved in water, are the antidotes, together with the free use of bland and mucilaginous drinks. Off. Prep.—Acidum Nitro-muriaticum; Acidum Muriaticum Dilutum; Calcii Chloridum ; Morphia Murias ; Quiniae Murias; Tinctura Ferri Chloridi; Unguentum Acidi Muriatici; Potassii Cyanuretum. ACIDUM HYDROCYANICUM. Hydrocyanic Acid. Prussic Acid. Cyano-hydric Acid. Preparation.—Take of sulphuric acid, one and a half ounces; water four fluidounces; mix, and when cool, put them into a tubulated glass retort, and add ferrocyanuret of potassium, two ounces, dissolved in distilled water, ten fluidounces. Pour eight fluidounces of distilled water into a cooled receiver, and having attached this to the retort, distil six fluidounces with a gentle heat. Lastly, add to this product five fluid- ounces of distilled water, or a sufficient quantity, so, that 12.7 grs. of nitrate of silver, dissolved in water, may be accurately saturated by 100 grs. of the acid, indicating two per cent, of real acid. Hydrocyanic Acid, when wanted for immediate use, may be prepared as follows : Add together one fluidounce of distilled water, forty-one grs. of muriatic acid, and fifty and a half grs. of cyanuret of silver; shake the mixture in a stopped vial, and when the precipitate has sub- sided, pour off the clear liquid. The acid should always be kept in a cool, dark place, and in closely stopped vials. AfJIDUM LACTICUM. 163 Chemical History.—The dilute, or medicinal hydrocyanic acid, is a transparent, colorless, volatile liquid, possessing a taste at first cooling, afterward somewhat irritating, and a peculiar smell. By exposure to light, it undergoes decomposition, and the bottles containing it should be covered with black paint or dark paper. Its constituents are carbon, nitrogen and hydrogen. Properties and Uses.—Hydrocyanic acid is the most deadly poison known, but is employed in medicine as a sedative and antispasmodic. It has been recommended in asthma, pertussis, spasmodic coughs, hypertrophy of the heart, neuralgia of stomach and bowels, and dys- pepsia, connected with morbid irritability of the stomach. Locally, it has been used in some cutaneous diseases, to allay the itching. Dose, half, to one drop, in gum-water or syrup. Much care must be used in its administration. Five drops have been safely given, by carefully and gradually increasing the dose. In cases where large doses do not prove immediately fatal, the anti- dotes most to be relied upon, are chlorine, diluted ammonia, cold affu- sion, and artificial respiration. ACIDUM LACTICUM. Lactic Acid. Preparation.—To six pints of milk, add eight ounces of bicarbonate of soda. Expose it to the air for some days, till it becomes sour, and saturate it with more soda. Repeat this as often as it becomes acid. Boil, filter, and evaporate to the consistence of syrup, and digest with alcohol. Filter the solution, and add sulphuric acid as long as it occa- sions a precipitate. Again filter, and concentrate the clear solution by evaporation, till its density is 1.215. Another mode of preparing this acid is, according to A. Beusch, to dissolve cane-sugar six pounds, and tartaric acid half an ounce, in boil- ing water twenty-six pounds, and set it aside for some days ; upon this, old stinking cheese eight ounces, well diffused in curdled acid milk from which the cream has been removed, are to be added to the above mixture along with finely-powdered chalk three pounds, the whole to be kept in a warm place, so that the temperature of the liquor shall be from 86° to 95°. It must be well stirred several times every day ; in the course of from eight to ten days the entire mass will solidify to a stiff paste of lactate of lime ; to this paste are to be added, boiling water twenty pounds, and caustic lime half an ounce, then boil for half an hour, and filter through a linen bag. The liquid is then to be evapo- rated to the consistency of a syrup, and set aside for four days, in which time the lactate of lime will separate in a granular crystalline form ; it 164 Materia Medica. must then be expressed, agitated with one-tenth its weight of cold water, again submitted to pressure, and this operation to be repeated two or three times. The lactate of lime, after being expressed as well as possible, is dis- solved in twice its weight of boiling water ; and for every pound of ex- pressed lactate of lime, three and a half ounces of sulphuric acid previ- ously diluted with its weight of water, must be added to the solution. The hot liquid is to be immediately filtered from the precipitated gypsum, through a conical bag, and then boiled with carbonate of zinc one and three-eighth pounds for every pound of sulphuric acid which has been used ; it must not be boiled longer than a quarter of an hour, if over this time, a very insoluble basic salt is formed. The solution, filtered boiling hot, soon deposits perfectly colorless lactate of zinc in crystalline crusts, which may be obtained perfectly free from sulphuric acid by rinsing with cold water. The mother-ley is to be again boiled with any of the salt which may have remained on the strainer, or con- centrated by evaporation. It yields nearly to the last drop, perfectly white lactate of zinc. To separate the lactic acid from this salt, dissolve it in seven and one- half parts of boiling water, pass a current of sulphureted hydrogen into the hot liquid until it has become cold and no further separation of sulphuret of zinc can be perceived. The liquid filtered from the sul- phui et of zinc is to be boiled to expel the excess of sulphureted hydro- gen, and then evaporated in a water-bath to the consistence of a syrup. Eight parts of lactate of zinc yield, in this manner, five parts of perfectly pure lactic acid. The separation of the lactic acid may likewise be accomplished by adding barytic water, which produces lactate of baryta, and precipitates the oxide of zinc ; the addition of sulphuric acid removes the baryta, and the filtered liquid is pure diluted lactic acid, which must be concen- trated by evaporation, in vacuo. The acid of sour crout is lactic acid, and by boiling it with carbonate of zinc, lactate of zinc may be obtained. Chemical Properties.—Hydrated lactic acid is a syrupy liquid, of a very strong but pleasant acid taste; its specific gravity is 1.215. At 482° the hydrate is decomposed and yields a solid crystalline sublimate called anhydrous, or sublimed lactic acid, lactide, which readily dis- solves in hot water, and if the solution be evaporated yields the original hydrate. The hydrated acid is inodorous, attracts moisture when ex- posed to the air, and is dissolved in all proportions by water or alcohol. It quickly dissolves oxalate of lime, and phosphate of lime, especially that which is contained in the bones, and hence has been recommended in oxalic and phosphatic urinary deposits. It is not employed in medi- cine in ics uucombined state, but is used in the preparation of Lactate of Acidum Nitricum. 165 Iron, and Lactate of Quinia. Albumen is coagulated by it. The for- mula of the hydrated acid is Ce H-, Oo+ HC. Magendie has proposed it as a remedy in certain forms of dyspepsia, and for the removal of phosphatic deposits in the urine. It may be taken in doses of from one to three drachms in the course of the day, and is best given in solution, sweetened with sugar. ACIDUM NITRICUM. Nitric Acid. Aqua Fortis. Preparation.—Nitric Acid is made from nitrate of potassa, by the agency of sulphuric acid—sulphate of potassa being formed, and nitric acid liberated in the form of gas. The acid gas is passed into a vessel of water, which absorbs it, and acquires acid properties. Chemical History.—The pure acid is transparent and colorless, and emits gray fumes of an irritating, peculiar odor, and has an intensely acid, corrosive taste. It stains the skin yellow, and corrodes and dis- solves all soft animal textures. The strongest acid has a specific gra- vity of 1.5 ; the ordinary acid of commerce, 1.3. It changes morphia to a red or yellow color, and is itself changed to a blood-red by the addition of brucia. Exposure of the acid to light, changes it more or less; and when left open to the air, it absorbs moisture and becomes weakened. When the acid is of a straw color, it is owing to the presence of nitrous acid. Most animal and vegetable bodies are converted into malic, carbonic, or oxalic acids, by the action of nitric acid diluted. This acid, acidifies sulphur and phosphorus, and oxidizes all metals, except gold, platinum, iridium, chromium, osmium, rhodium, cerium, columbium, and titanium; but when mixed with muriatic acid, a mutual decomposition takes place, and aqua regia or nitro-muriatic acid is formed, which is capable of dissolving gold. Nitric acid is often rendered impure by the presence of sulphuric acid, or chlorine ; a few drops of the solution of chloride of barium to the nitric acid, diluted with three or four parts of distilled water, will pro- duce a cloud, if sulphuric acid be present; and a similar application of a few drops of a solution of nitrate of silver, will produce a cloud if chlorine be present. The acid of commerce sometimes contains iodine, which may be detected by saturating the suspected acid with a carbon- ated alkali, then pouring in a little clear solution of starch, and finally, adding a few drops of sulphuric acid. If iodine be present, the sulphu- ric acid will set it free, and the starch solution will become blue. When nitric acid is added to a solution of glue, it prevents it from forming a jelly, and makes what is called a " liquid glue," which is very 166 Materia Medica. convenient for cabinet-makers, joiners, pasteboard-workers, toy-makers, etc., inasmuch as it is applied cold. This liquid glue is made by taking two and one-fifth pounds of good glue, and dissolving it in two and one- ninth pints of water, in a glazed pot over a gentle fire, or still better, m the water-bath, stirring it from time to time. When all the glue is melted, pour in, in small quantities at a time, of nitric acid specific gravity 1.32, seven ounces avoirdupois. This addition produces an effer- vescence, owing to the disengagement of hypo-nitrous acid. When all the acid is added, remove the vessel from the fire, and allow it to cool. This preparation preserves nearly all the primitive qualities of the glue, may be kept in an open vessel for years, without undergoing any change, and will be found very convenient in chemical operations ; gases may be preserved by it, by covering strips of linen with it. Properties and Uses.—Escharotic, epispastic, tonic, refrigerant, expec- torant, antiseptic, and syphilitic. Largely diluted with water, it forms a good acid drink in febrile diseases, especially where there is a disposi- tion to prostration or putrescency. It has also been serviceable in some forms of syphilis and chronic hepatitis. Externally it has been applied, in a dilute form, say twelve or fifteen minims to the pint of water, to ulcers of an indolent or phagedenic character, and in various chronic eruptions, porrigo of the scalp, etc. ; and has likewise been used for destroying warts, and cauterizing poisoned wounds. In the treatment of piles, nitric acid, is said to be very efficacious; the small tumors may be destroyed by a single application of it, while the larger may require two or three applications. If the tumors cannot be extruded from the anus, a speculum must be used. The acid may be applied by a bit of sponge not larger than a grain of wheat, attached to a gold or glass probe. The severe pain which usually follows may be relieved by morphine exhibited internally, and lard, or opiate supposito- ries applied locally. If too much acid has been applied, extending to contiguous parts, and causing unnecessary pain, it may be neutralized by applying a piece of sponge or cotton, saturated with soda or potassa. Dr. Dixon expresses a hope, grounded on the successful results of its application, that all cases of piles may thus be cured, with greater cer- tainty than by excision or ligation. For several years past I have used nitric acid as a local application to chancre in hundreds of instances, and have not yet heard of any return of the disease, either in a secondary or tertiary form. It must be applied while the chancre is in the pustular form, and unbroken, and before the virus is acted upon by the oxygen of the atmosphere, and consequently, previous to its absorption in the system. As soon as the pustule is discovered, the physician will open it, and apply several drops of undiluted nitric acid to it, thus destroying the virus at once, and curing the disease in a few minutes. The pain occasioned is hardly Acidum Nitrohydrochloricum. 167 noticed by some patients. Sometimes, I subsequently wash the ulcer with the muriated tincture of iron, which is one of the best local appli- cations to a chancre with which I am acquainted. No other treatment is required, unless for the purpose of allaying the patient's fears. Since having introduced this employment of the acid to the profession, many have employed it, and uniformly with successful results. The dose of nitric acid is from five to twenty minims, given two or three times a day; the diluted acid, which is the most convenient for prescription, may be made by adding one fluidounce of nitric acid to nine fluidounces of distilled water. The dose of which is from twenty to forty drops, in two or three fluidounces of water. When swallowed internally, without dilution, nitric acid almost always proves fatal; the same means may be employed to counteract its effects as named for hydrochloric acid. Off. Prep.—Acidum Nitro-muriaticum ; Acidum Nitricum Dilutum ; Spiritus ^Etheris Nitrici; Unguentum Acidi Nitrici. ACIDUM NITROHYDROCHLORICUM. Nitrohydrochloric Acid. nitromuriatic acid, aqua regia. Preparation. — The usual form for preparing this acid is to combine one part, by measure, of nitric acid, with two parts of hydrochloric acid; but as I introduce it here merely because it enters into the formula for the White Liquid Physic, given below, I will state that in this instance it should be made of equal parts of nitric and muriatic acids. This acid promptly dissolves gold, and as it readily parts with its chlorine, it, together with its preparations, should always be preserved in close bottles. Properties and Uses.—Similar to the above mineral acids. Bathing with a dilute solution of this acid, say one part of acid to six of water, is asserted to have cured several cases of obstinate constipation. Dose, three or four drops, sufficiently diluted. A preparation has been highly recommended, called White Liquid Physic, or Dow's Physic. It is made as follows: Take sulphate of soda, half a pound; water, one and a half pnnts; dissolve, and then add, nitromuriatic acid, two fluidounces, powdered alum, one drachm and eight grains. This preparation is used as a cooling purgative, also to allay nausea and vomiting—for colic, hepatic diseases, diarrhea, etc. Given by some as a substitute for mercury. In intermittent fever, given in laxative doses, it has proved highly beneficial, especially when occurring in 168 Materia Medica. broken-down constitutions, and has cured the most obstinate cases of dysentery. Dose, one tablespoonful in a gill of water, three times a day—or, in dysentery, given every hour, until it slightly operates on the bowels, after which, every three or four hours. The above is the origi- nal recipe, and the additions of sanguinaria, etc., are uncalled for. A preparation which is highly recommended for the cure of corns, warts, cancers, etc., Dr. Bleeker's remedy, is said to be a compound of nitro-muriatic acid and cobalt. ACIDUM OXALICUM. Oxalic Acid. History.—Oxalic Acid is found in animals and in vegetables; it is formed sometimes during abnormal conditions of the kidneys, and is deposited in the bladder as oxalate of lime, giving rise to the mulberry calculus. It is also found combined with potassa in the common sorrel, and wood-sorrel, and united with lime in the roots of rhubarb, valerian, and other plants. Preparation.—It is usually obtained by the decomposition of sugar with nitric acid. Four parts of sugar are acted upon by twenty-four parts of nitric acid of specific gravity 1.22, and the mixture is heated so long as any nitric oxide is disengaged. A part of the carbon of the sugar is converted into carbonic acid, by oxygen derived from the nitric acid, which is thereby partially converted into nitric oxide. The unde- composed nitric acid, reacting on the remaining elements of the sugar, generates oxalic and malic acids, the former of which crystallizes as the materials cool, while the latter remains in solution. The crystals being removed, a fresh crop may be obtained by further evaporation. The thick mother-water which now remains is a mixture of malic, nitric, and oxalic acids; and by treatment with six times its weight of nitric acid, the greater part of the malic acid will be converted into oxalic acid. The new crop of crystals, however, will have a yellow color, and contain a portion of nitric acid, the greater part of which may be got rid of by allowing them to effloresce in a warm place. Many substances beside sugar yield oxalic, by the action of nitric acid ; as for example, starch, gum, wool, hair, silk, and many vegetable acids. In every case in which it is thus generated, the proportional excess of oxygen which it contains, compared with every other organic compound, is furnished by the nitric acid. Organic substances yield oxalic acid also, when heated with potassa. Thus shavings of wood, if mixed with a solution of caustic potassa, and exposed to a heat considerably higher than 212°, will be partially decomposed and converted into oxalic acid, which then combines with the alkali. This process constitutes, perhaps, the cheapest method of obtaining oxalic acid. Acidum Phosphoricum Dilutum. 169 Chemical Properties. — Oxalic acid is a colorless crystallized solid, possessing considerable volatility, and a strong sour taste. Its crystals have the shape of slender, flattened, four or six-sided prisms, with two- sided summits; and, when exposed to a very dry atmosphere, undergo a slidit efflorescence. It dissolves in about nine times its weight of cold, and in about its own weight of boiling water. i*The solution of the crystals takes place with slight crepitation. It dissolves also, but not to the same extent, in alcohol. The presence of nitric acid renders it more soluble in water. It combines with salifiable bases, and forms salts called oxalates. The most interesting of these are the three oxalates of potassa, severally called oxalate, binoxalate, and quadroxalate, and the oxalate of lime. The binoxalate of potassa or salt of sorrel, some- times improperly called the essential salt of lemons, is employed for removing iron-molds from linen, and acts by its excess of acid which forms a soluble salt with the sesquioxide of iron constituting the stain. Oxalic acid is used for removing ink stains and iron-molds, for cleaning the leather of boot-tops, and for discharging colors in calico-printing. Properties and Uses.—This article is a poison, and an unfit agent for internal administration. Externally, a saturated aqueous solution of it is useful in cutaneous cancer, acne, and several forms of cutaneous dis- ease. The saturated solution neutralized by caustic potassa, forms an excellent application to discuss indolent tumors. In cases, where this article has been taken internally, it has produced death in a short time. The antidotes are chalk or magnesia, mixed with water, and followed by emetics. ACIDUM PHOSPHORICUM DILUTUM. Diluted Phosphoric Acid. Preparation.—Take of Phosphorus, an ounce ; Nitric acid four fluid- ounces; Distilled Water ten fluidounces, (imperial measure). Add the phosphorus to the- nitric acid, mixed with the water in a glass retort placed in a sand-bath; then apply heat until eight fluidounces are distilled. Put these again into the retort, that eight fluidounces may distil, which are to be rejected. Evaporate the remaining liquor in a platinum capsule until only two ounces and six drachms remain. Lastly, add to the acid, when it is cold, as much distilled water as may be suf- ficient to make it accurately measure twenty-eight fluidounces. The specific gravity of this acid is 1.064. One hundred grains of it saturate forty-two grains of carbonate of soda. Chemical Properties.—Diluted Phosphoric Acid is a colorless, inodor- ous, sour liquid, acting strongly on litmus and possessing powerful acid 170 Materia Medica. properties. If it be saturated by ammonia, nitrate of silver occasions a yellow precipitate of phosphate of silver. Arsenious acid is the only acid similarly acted on; and it may be determined from phosphoric acid by the action of sulphureted hydrogen, which causes a yellow precipi- tate with the arsenious acid, while it has no effect at all upon the phos- phoric. When concentrated till the temperature attains 300°, diluted phosphoric acid acquires its greatest state of concentration, and presents the appearance of a brown oily liquid, which consists of one equivalent of acid, and three of water. Although evaporated so as to become dense, it does not act upon animal and vegetable matter like sulphuric acid. The acid may be obtained in crystals, by evaporating the brown oily liquid, mentioned above, in vacuo. From its saturating power, diluted phosphoric acid is shown to contain 10.5 per cent, of real phos- phoric acid. If the brown oily liquid be deprived of its water by a long continued heat of 415°, one equivalent of its water is disengaged, and the acid acquires new properties, and a yellow precipitate will no longer be occasioned by nitrate of silver. When the diluted acid is evaporated to dryness, and heated to redness, it becomes a transparent, white, brittle, fusible solid, formerly named Glacial Phosphoric Acid, but now termed Metaphosphoric Acid. Properties and Uses.—Diluted phosphoric acid is tonic and refriger- ant, and is asserted to prevent the morbid secretion of bony matter, cor- rect urinary phosphatic deposits and to allay pain and spasm. It has likewise been recommended in hysteria, diabetes, and leucorrhea. It is very useful in cases of impotency from masturbation, to improve the condition of the sexual ogans. Externally, it has been applied to tedious and obstinate ulcers. Dose, from ten to thirty drops, two or three times a day, diluted with a few ounces of water. Off. Prep.—Ammoniae Phosphas ; Ferri Phosphas; Sodae Phosphas. ACIDUM SULPHURICUM AROMATICUM. Aromatic Sulphuric Acid. Elixir of Vitriol. Preparation.—Take of sulphuric acid, three fluidounces and a half; ginger, bruised, an ounce; cinnamon, bruised, an ounce and a half; drop the acid gradually into the alcohol, and digest in a close vessel for three days; then add the ginger and cinnamon, and macerate for a week ; lastly, filter through paper. History.—This is a reddish-brown liquid, of a peculiar aromatic odor, and when sufficiently diluted, of a grateful acid taste. It consists of sulphuric acid diluted with alcohol, and containing the essential oils of Cinnamon and Ginger. Acidum Sulphuricum Dilutum. 171 Properties and Uses.—It possesses the same properties as sulphuric acid, for which it is generally substituted in this country. The dose is from ten to thirty drops in sweetened water; care must be taken that it does not injure the teeth. ACIDUM SULPHURICUM DILUTUM. Diluted Sulphuric Acid. Oil of Vitriol. Preparation.—Take of sulphuric acid, one fluidounce; distilled water, thirteen fluidounces. Gradually add the acid to the water, in a glass vessel, and mix them. The specific gravity of this acid is 1.09. History.—Sulphuric Acid is obtained by burning sulphur, mixed with one-eiafhth its weiaht of nitre, over a stratum of water, contained in a chamber lined with sheet-lead. It is a dense, colorless, inodorous liquid, of an oleaginous appearance, and possessing strong corrosive qualities. When pure its sp. gr. is 1.845. It acts powerfully on organic bodies, whether animal or vegetable, depriving them of the elements of water, developing charcoal, and turning them black. On the living fiber it acts as a powerful caustic. The density of the commercial acid varies be- tween 1.835 and 1.840 or upward. If greater than 1.845, it indicates an unusual amount of impurity. It freezes about 36° below zero, and boils a little above 600°. It has a powerful affinity for water, so as to attract it quickly from the atmosphere, and also from many other bodies through the medium of the atmosphere, if confined together in a cir- cumscribed place. It unites with water in all proportions, with some condensation of volume, and the evolution of much heat, which is apt to crack glass vessels, which may be avoided by adding the acid gradually. Properties and Uses.—Diluted Sulphuric Acid is tonic, refrigerant, and astringent. It has been used in low typhoid fevers, and in conva- lescence from protracted fevers, as a tonic. As an astringent, it has been employed in colliquative sweats, passive hemorrhages, and diarrhea. Likewise used in phosphatic calculous affections. Externally, employed in gargles for ulcerated sore-throat, to check excessive ptyalism, and as a wash for cutaneous eruptions, and ill-conditioned ulcers. Dose, from ten to thirty drops, three times a day, in a wineglassful of plain or sweetened water. To preserve the teeth, it were better to suck it through a quill or glass tube. Off.

ACIDUM TANNICUM. Tannic Acid. Tannin. Preparation.—Cause sulphuric ether to percolate through any quan- tity of powdered galls, in a glass adapter, having the lower end loosely closed with carded cotton. The liquor obtained in the receiver separates into two parts, and the ether must be allowed to percolate through the galls until the lower stratum of liquid in the receiver no longer increases. Pour off the upper layer, and evaporate the lower portion with a moder- ate heat, to dryness. M. Sandrock states that a much larger quantity of Tannic Acid may be obtained by employing a mixture of sixteen parts of ether and one part of alcohol. The percolated liquid separates into two layers. The lower one contains the tannic acid, which may be obtained perfectly pure on evaporation; the upper layer contains the gallic acid, coloring matter, and some tannic acid. The tannic acid in the upper layer may be had by evaporating the liquid to dryness, treating the residue with pure ether, until the lower of the two layers into which the liquid sepa- rates, no longer presents a green color ; and then separating it, adding if necessary a little alcohol, and evaporating. Chemical Properties.—Pure Tannic Acid is solid, uncrystallizable, white, or very slightly yellowish, inodorous, strongly astringent to the taste, without bitterness, very soluble in water, much less soluble in alcohol and ether, especially when anhydrous, and insoluble in the fixed and volatile oils. It may be kept unchanged in the solid state. Exposed to heat, it partly melts, swells up, blackens, takes fire, and burns with a brilliant flame. The aqueous solution, when exposed to the air, gradually becomes turbid, and deposits a crystal- line mattei^ consisting chiefly of gallic acid. During the change, oxygen is absorbed, and an equal volume of carbonic acid disen- gaged. Tannic acid has an affinity for acids, and when in solution affords precipitates with the sulphuric, nitric, muriatic, phosphoric, and arsenic acids, but not with the oxalic, tartaric, lactic, acetic, or citric. The precipitates are compounds of tannic acid with the respective acids, and are soluble in pure water, but insoluble in water with an excess of acid. Hence, in order to insure precipitation, it is necessary to add the acid in excess to the solution of tannic acid. This principle also unites with most of the salifiable bases. With potassa, it forms a compound but slightly soluble, and is therefore precipitated by this alkali, or its carbonates, from a solution which is not too dilute, though a certain ex- cess of alkali will cause the precipitate to be re-dissolved. Its combin- ation with soda is much more soluble, and this alkali affords no precipi- tate, unless with a very concentrated solution of tannic acid. With ammonia, its relations are similar to those with potassa. Many of the Acidum Tannicum. 173 metallic salts are precipitated by tannic acid even in the uncombined state, especially those of lead, copper, silver, uranium, chromium, mercury, and the protosalts of tin. With the sesquisalts of iron it forms a black precipitate, which is a compound of tannic acid and the sesquioxide of iron, and is the basis of ink. It does not disturb the solutions of the pure protosalts of iron. Several of the alkaline salts precipitate tannic acid from its aqueous solution, either by the formation of insoluble com- pounds, or by simply extracting the solvent. Tannic acid unites with all the vegetable alkalies, forming compounds which are for the most part of a whitish color, and but very slightly soluble in water, though they are soluble in the vegetable acids and in alcohol, and in this latter respect differ from most of the compounds which tannic acid forms with other vegetable principles. On account of this property of tannic acid, it has been employed as a test of the vegetable alkalies; and it is so delicate that it will throw down a precipitate from their solution even when they are too feeble to be disturbed by ammonia. It precipitates also solutions of starch, albumen, and gluten, and forms with gelatin an insoluble compound, which is the basis of leather. Its ultimate con- stituents are carbon, hydrogen, and oxygen.— U. S. Disp. Properties and Uses.—A pure astringent. Used in chronic dysentery and diarrhea, and in uterine and other passive hemorrhages, and as a wash or injection to remove chronic mucous discharges, as in bronchial catarrh, gonorrhea, gleet, leucorrhea, etc. It has likewise been recom- mended in diabetes, combined with opium, and to arrest excessive per- spiration— also in conjunction with morphia, in Asiatic Cholera. Ex- ternally, it has been successfully used in excoriation, prolapsus ani, piles, fissure of the anus or rectum, sore nipples, phagedenic ulcers, aphthous ulceration of the mouth, sore-throat, severe salivation, and in tooth- aches, in solution with ether. It may be employed in form of a wash, by adding five grains to a fluidounce of water; or in ointment, one part of the acid to fifteen of lard. It is a valuable remedy, the only disadvan- tage being its tendency to produce constipation, which may be avoided by the addition of a small quantity of podophyllin, in cases where this resin is not contra-indicated. Tannic acid should not be given during the presence of active inflamma- tion. Several cases of cholera in the collapsed stage, have been cured by Prof. R. S. Newton, by doses of ten or fifteen grains of Tannic Acid, repeated every ten or fifteen minutes, until the discharges ceased ; and continuing it afterward at longer intervals, with other appropriate treat- ment. The Geraniin is now usually preferred by Eclectic practitioners to the Tannic acid, as it does not leave the tissues upon which it acts so harsh and dry, as is the case with the latter agent. Dose of Tannic acid, from half a grain to five grains. Off. Prep.—'Ferri Tannas ; Quiniae Tannas. 174 Materia Medica. ACIDUM TARTARICUM. Tartaric Acid. Preparation.—Saturate the excess of acid in bitartrate of potassa with carbonate of lime ; decompose the resulting insoluble tartrate of lime by sulphuric acid; then decompose the remaining neutral tartrate of potassa by chloride of calcium in excess ; finally, decompose the resulting tar- trate of lime by sulphuric acid, as at first; then strain off the liquid, and crystallize by evaporation. Chemical Properties.—Tartaric Acid is a white, crystallized solid, in the form of irregular six-sided prisms. Sometimes two opposite sides of the prism become very much enlarged, so as to cause the crystals to present the appearance of tables. It is unalterable in the air, and pos- sesses a strong acid taste, which becomes agreeable when the acid is sufficiently diluted with water. It is soluble in five or six times its weight of cold, and twice its weight of boiling water. It is also soluble in alcohol. A weak solution undergoes spontaneous decomposition by keeping, becoming covered with a moldy pellicle. In the form of crys- tals it always contains combined water, from which it cannot be separated without previous combination with a base. Its most usual impurity is sulphuric acid, which may be detected by the solution affording, with acetate of lead, a precipitate only partially soluble in nitric acid. Tartaric acid is incompatible with salifiable bases and their carbonates, with salts of potassa, and with the salts of lime, and of lead. It consists, when dry, of two equivalents of hydrogen 2, four equivalents of carbon 24.48, and five equivalents of oxygen 40=66.48; and when crystal- lyzed, of one equivalent of dry acid 66.48, and one equivalent of water 9=75.48. Properties and Uses.—Tartaric acid is refrigerant, antiseptic, and anti- scorbutic. It is used as a drink in febrile and inflammatory diseases ; being cheaper than citric acid, it forms, when dissolved in water and sweetened, a good substitute for lemonade. It is very much used in medicine, to form acid refrigerant drinks and effervescing draughts. What are called Soda powders consist of twenty-five grains of tartaric acid, and half a drachm of bicarbonate of soda, put up in separate papers. When used, the acid and salt are dissolved in separate portions of water, and the solutions mixed and drank in a state of effervescence. These powders furnish a good substitute for soda water. Tartaric acid is also a consti- tuent in the gentle aperient called Seidlitz powders. These consist of a mixture of two drachms of tartrate of potassa and soda, (Rochelle salt,) and two scruples of bicarbonate of soda, put up in a white paper, and thirty-five grains of tartaric acid, contained in a blue one. The contents of the white paper are dissolved in about half a pint of water, to which ACONITUM NAPELLUS. 175 those of the blue paper are added ; and the whole is taken in a state of effervescence. A colorless solution of sulphate of quinia has long been employed by Eclectics; it may be made by adding equal parts of tar- taric acid and sulphate of quinia to as much water as may be desired. Off.

Ord.—Ranunculacese. Sex. Syst.—Polyandria Trigynia. LEAVES AND ROOT. Description.—This is a perennial herbaceous plant, also known by the name of Wolfsbane; it has a turnip-shaped or fusiform root, from three to six lines in diameter, and three or four inches long; externally brown- ish, internally whitish and fleshy, and sending off many long, thick, fleshy fibers. When the plant has> arrived at maturity, there are usual- ly two roots united, the older of which is dark-brown, and supports the stem; the younger is of a light yellowish-brown, and is destined to fur- nish the stem of the following year. The stems are simple, erect, round and smooth ; the leaves are alternate, petiolate, divided to the base into five wedge-shaped lobes, which are called trifid, deep green upon their upper surface, light green beneath, and smooth and shining on both sides. The flowers are of a dark violet-blue color, large, in a terminal raceme, short pedicels ; the raceme is simple and cylindrical. The peta- loid sepals are five; the upper being helmet-shaped and concealing the petals ; the lateral broad and rounded ; the lower oblong and deflected. The petals not more than two, supported on a peduncle or claw, and have a hooked spur, and a bifid and revolute lip. The stamens are fili- form, converging, with whitish anthers. The ovaries are from three to five, smooth, with simple reflected stigmas. The capsules correspond in number with the ovaries, and contain many wrinkled and angular seeds. History.—Monkshood or Aconite is a native of most parts of Europe, growing in mountain forests and plains, and is cultivated as an orna- mental plant in the gardens of Europe and this country. It grows from two to six feet high, and bears a long, dense spike of beautiful, deep- blue flowers, which make their appearance in May and June. The root, which consists of numerous slender radicles, is the most powerful part of the plant, but every portion of it is possessed of highly deleterious properties. There are several varieties, but the A. Napellus and A. Panicidatum are the only officinal ones. The dried leaves and root retain their acridity and narcotic virtues; and the expressed juice 176 Materia Medtca. possesses the properties of the plant. Its medicinal virtues are best extracted by alcohol, and the alcoholic extract is the most convenient and energetic preparation. It contains an alkaloidal principle, termed Aconita, or Aconitina, a black oily matter, albumen, muriate and sul- phate of lime, starch, etc. The smell of the plant is feeble but nauseous, and its taste acrid and bitter, leaving in the mouth a sensation of heat and pungency, and a degree of numbness. Properties and Uses.—Aconite is an energetic acro-narcotic poison in improper doses, occasioning symptoms of gastric irritation, a peculiar tino-ling and numbness of the mouth, followed by loss of sensation, and paralvsis of the voluntary muscles, but without coma or convulsions. With these symptoms will be thirst, nausea, vomiting, purging, spasms of the stomach and intestines, headache, dimness of vision, the pupils beino- either dilated or contracted, excessive prostration, pallid coun- tenance, cold extremities, very feeble pulse, and delirium. Death ensues from paralysis of the respiratory muscles. All the above effects are not experienced in every case, though several of them will always be pre- sent. On dissection, inflammation of the stomach and bowels is found, with engorgement of the brain and lungs. There is no antidote known for poisoning with monkshood, yet a timely and thorough evacuation of the stomach, with the internal and external use of stimulants, have restored persons in imminent danger to perfect health. In maximum medicinal doses, it warms the stomach and general sys- tem, and sometimes occasions nausea, with tingling and numbness in the lips and fingers, debility of the muscles, force and frequency of pulse diminished, as well as a diminution of the frequency of respiration. Sometimes the tingling and numbness extend over the whole body, with headache, vertigo, neuralgic pains, and general prostration. It should never be given in sufficient quantity to produce these effects. Applied to the eye, Aconitum causes contraction of the pupil. In anaemical headaches, and in all cases attended with a torpid or paralytic condition of the muscular system, its use is contra-indicated. It is a very useful antiphlogistic remedy, and possesses anodyne, seda- tive, diaphoretic and diuretic qualities. It is especially useful in febrile and inflammatory diseases, gout, rheumatism, epilepsy, and neuralgic affec- tions. In scarlatina, inflammatory fever, acute rheumatism, pneumonia, peritonitis, gastritis, and many other acute disorders, it has been used with the most decided advantage. Its action is more especially displayed in the higher grades of fever and inflammation. The best preparation is the alcoholic extract, formed by evaporating a tincture made of a pound of aconite and a quart of alcohol. The dose is one-eighth of a grain. One part of the extract, with two of lard, forms an excellent ointment for painful affections. The powdered root or leaves may be given in one or two grain doses, gradually increased. The tincture, ACONITINA. 177 made by macerating one ounce of the powdered root with six ounces of alcohol, for two or three weeks, may be given in doses of eight or ten drops, three times a day, gradually increased, until its effects are ob- vious. Its continued use sometimes produces vomiting and diarrhea. Off. Prep.—Extract. Aconiti Alcoholicum ; Tinctura Aconiti; Em- plastrum Extracti Aconiti Radicis. ACONITINA. Aconitina. Preparation.—Take of Aconite root, dried and bruised, two pounds; rectified spirit, three gallons; diluted sulphuric acid, solution of am- monia, (Water of Ammonia, U. S.,) purified animal charcoal, each a sufficient quantity. Boil the aconite with a gallon of the spirit, for an hour, in a retort with a receiver fitted to it. Pour off the liquor, and again boil the residue with another gallon of the spirit and with the spirit recently distilled, and pour off the liquor also. Let the same be done a third time. Then press the aconite, and having mixed all the liquors and filtered them, distil the spirit. Evaporate the remainder to the proper consistence of an extract. Dissolve this in water and filter. Evaporate the solution with a gentle heat, so that it may thicken like syrup. To this add of diluted sulphuric acid, mixed with distilled water, sufficient to dissolve the aconitina. Next drop in solution of ammonia, and dissolve the precipitated Aconitina in diluted sulphuric acid, mixed, as before, with water. Then mix in the animal charcoal, occasionally shaking for a quarter of an hour. Lastly, filter, and having again dropped in solution of ammonia, so as to precipitate the aconitina, wash and dry it. Chemical Properties.—Aconitina, when freshly precipitated, is said to be white, and in the form of a hydrate ; but it speedily parts with its water, and forms a brownish, brittle mass. It is thought not to be crystallizable. When obtained by evaporating its alcoholic solution, it is described as being in the form of a transparent, colorless mass, having a glassy luster. In powder, it is white, with a yellowish tinge. It is inodorous, and of a bitter and acrid taste, producing a benumbing im- pression on the tongue. It is unalterable in the air, and fusible by a gentle heat. It is sparingly soluble in water, requiring for solution 150 parts of cold, and 50 of boiling water ; alcohol or ether dissolves it readily. It neutralizes the acids ; but its salts are not crystallizable. That it contains nitrogen is proved by the evolution of ammonia, when it is decomposed by heat. It is incompatible with tinctures of iodine, and galls. 12 178 Materia Medica. Properties and Uses.—Aconitina is too powerful a poison to be used as an internal medicine, yet as an external application, Dr. Turnbull has found it useful in gout, rheumatism, neuralgia, and diseases of the heart. He employed it in the form of tincture or ointment—one grain to one fluidrachm of alcohol, gradually increased to even eight grains; or two grains rubbed first with six drops of alcohol, and then with a drachm of lard, applied by friction three or four times a day; and to be of service, it must produce a sensation of heat and prickling, followed by numbness and a feeling of constriction. It should not be applied to an abraded surface, or to a mucous membrane, lest it prove dangerous. ACORUS CALAMUS. Calamus. Nat. Ord.—Araceas. Acoraceas. Sex. Syst.—Hexandria Monogynia. the rhizoma. Description.—Calamus, sometimes called Sweet Flag, has a perennial, horizontal, jointed, and compressed root or rhizome, from six to twelve lines thick, and several feet in length, and which sends off numerous, long, round, and slender radicles, of a whitish or yellowish color, also bunches of brown fibers from its joints, which resemble coarse hair; internally the root is white and spongy, externally whitish with a tinge of green, and the joints are from half an inch to an inch in length, and are variously shaded with different tints of white and red. The leaves are radical, sheathing at the base, long, sword-shaped, smooth, green above, but of a reddish color below, variegated with green and white. The scape or flower-stem resembles the leaves, is usually longer, and from one side near its middle it sends out a naked, solitary, oblique, and cylindrical spadix, tapering at each end, about two inches in length, and closely covered with small, pale or yellowish-green flowers, which have no scent except when bruised. These are without calyx, and have six equal truncated scales, inclosing six stamens, having thick filaments and bilobate anthers. The ovary is sessile, three-celled, with a pointed stigma. The capsule is several-seeded. History.—Calamus is found in most parts of the world, growing on the borders of small streams, ponds, wet meadows, swamps, etc., and flow- ering in May and June. The part used is the root or rhizome. It should be collected late in the autumn, or in the spring, washed, deprived of its fibers, and dried with a moderate heat. The dried roots of the shops are of various lengths, somewhat flattened, of a yellowish-brown color externally and wrinkled, internally whitish, or yellowish-white, and ACT^EA. m of light and spongy texture. Water or alcohol take up its virtues. It has a strong and fragrant odor, and a warm bitterish aromatic taste. It contains volatile oil, resin, extractive, etc.; the oil is lighter than water, and is pale-yellow, very odorous and pungent. Properties and Uses.—A stimulating tonic, and aromatic. Useful in flatulent colic, dyspepsia, atonic conditions of the stomach, various affec- tions of the alimentary canal, and as an adjuvant to quinia and bark in intermittents. It forms an excellent substitute in syrup for Godfrey's Cordial. Externally, it is a valuable application to indolent ulcers, and to keep up the discharge from blistered surfaces and issues. Dose of the infusion, made by scalding an ounce of the root in a pint of water, from four to six fluid ounces ; of the root, from a scruple to a drachm. In flatulent colic of infants, it is best combined with magnesia. Off. Prep.—Decoctum Acorus; Infus. Acorus. ACTAEA. Actaea Alba.—White Cohosh. Actaea Rubra.—Red Cohosh. Actaea Spicata.—Baneberry. Nat. Ord.—Actasa. Sex. Syst.—Polyandria Monogynia. THE RHIZOMA. Description.—Actaea Alba, sometimes called White Baneberry, is about two feet high, with large, decompound leaves; raceme oblong, with pedicels as large as the general peduncle; petals truncate at the apex, and equaling the stamens; berries milk-white; flowers white and appear- ing late in May. Actaea Rubra or Red Baneberry, is about two feet high, with large decompound leaves; raceme ovoid or hemispherical, petals acutish and shorter than the stamens ; pedicels of the hemispheric raceme, slender and less than the full grown peduncles ; berries oval, ripe in summer, cherry red, and forming a raceme three to four inches long ; flowers white, and appearing in April and May. The above two plants are natives of this country, they are perennial, herbaceous, and found in the rich deep mold of shady and rocky woods, from Canada to Virginia. Actaea Spicata, sometimes called Herb-Christopher, is a European plant, generally found in mountainous woods, and attaining the hight of two or three feet. The stem is erect, leafy, triangular, and but little branched; the root is creeping and perennial: the leaves are petiolated, 180 Materia Medica. twice or thrice ternate ; leaflets ovate, lobed, unequally serrate ; flowers white, in a terminal, solitary ovate spike ; pedicels simple, downy, brac- teate at the base. Sepals four, deciduous ; petals spatulate ; stamens sub- ulate ; ovary ovate, with a round, sessile stigma; berries purplish black, succulent. History.—The root is of a dark-brown color, with a sweetish, nauseous odor, but which is greatly dissipated by drying ; the taste is bitterish and acrid. The berries are poisonous, causing delirium and death, or a species of intoxication accompanied with derangement of the cerebral functions, and irritation of the digestive organs. Properties and Uses.—The recent root of Actaea Spicata is a violent purgative, resembling that of the black hellebore in its action; when dried it is not so active. It is seldom employed internally. A decoction used locally is said to cure the itch, and to destroy lice. The A. Alba and A. Rubra, possess similar qualities; they are said to possess purgative and emmenagogue properties, and are viewed as substi- tutes for the Cimicifuga Racemosa, and Caulophyllum Thalictroides; but this is undoubtedly an error. ADEPS. (Axungia, Ed. Adeps Suillus Preparatus, Dub.) LARD. THE PREPARED FAT OF THE SUS SCROFA OR COMMON HOG, FREE FROM SALT. History.—Good lard is white, inodorous, granular in appearance, of a sweetish taste, smooth to the touch, of a soft consistency at ordinary temperatures, fusible at about 100° F., insoluble in water, sparingly soluble in alcohol, more so in ether and the volatile oils, is dissolved and decomposed by the stronger acids, and is converted into soap when boiled with caustic alkaline solutions. When melted it readily unites with resins and wax, on which account it is extensively used in making ointments and liniments. When heated in close vessels, it undergoes a species of destructive distillation, by which margaric, oleic, acetic, and probably benzoic acids are formed, together with other less important modifications of its constituent fatty principles. It consists of three neutral fatty principles, called olein, stearin and margarin, which are found in most animal-oils and fats, and upon the relative proportions of which depends their consistence respectively. Olein, is the liquid principle of oils ; when pure it is colorless, has a sweetish taste, little odor, is insoluble in water, soluble in boiling alco- hol, readily soluble in ether, and congeals at 20° F. It is convertible by saponification into glycerin, margaric acid, and oleic acid, and con- Adiantum Pedantum. 181 sists of carbon, hydrogen, and oxygen. Lard contains 62 per cent, of olein, which is extensively used for burning in lamps. Stearin is white, concrete, of a crystalline appearance like spermaceti, pulverizable, fusible at 144°, soluble in boiling alcohol or ether, inso- luble in either of these fluids when cold, and convertible by saponifica- tion into a peculiar fatty acid, named stearic acid, and glycerin. It consists also of carbon, hydrogen, and oxygen, and may be separated from the concrete matter of lard, by treating this with cold ether so long as anything is dissolved ; the stearin is left behind, and the ethe- real solution yields margarin by evaporation. Margarin very closely resembles stearin, but is more fusible; one variety, obtained from animal fats melting at 118°, and being soluble in cold ether; another variety, from vegetable oils, melts at 82°. Lard should be kept in well closed vessels, as if exposed to the air it absorbs oxygen, and becomes rancid, and consequently unfit for medicinal use. When pure it consists of 62 per cent, of olein, and 38 per cent, of stea- rin and margarin together. Properties and Uses.—Lard is emollient. It is sometimes used alone in frictions, and is frequently added to laxative enemata; but its chief use is as an ingredient for cerates and ointments. When applied to blistered surfaces, care must be taken that it be not rancid, as it is then apt to cause ulceration. ADIANTUM PEDATUM. Maidenhair. Nat. Ord.—Filices, or Polypodiaceas. Sex.

Description.—Adiantum Pedatum is a delicate and most graceful fern, growing from twelve to fifteen inches high, with the stipe or stalk and rachis, slender, polished, and black or dark-purplish, very glabrous; the frond or leaf pedate, with pinnate branches ; the pinnae halved, tri- angular-oblong, entire on the lower margin from which the veins all pro- ceed, and incised at the upper and fruit-bearing margin ; the barren seg- ments are toothed, the fertile ones entire. Nonlinear, oblong ; arranged along the margin of the frond; involucre formed by turning back the margin of the frond over the sori, and it opens inward. Petiole smooth. History.—This plant is perennial, and is found in deep woods on moist, rich soil, throughout the United States. The leaves are bitterish and somewhat aromatic, and yield their properties to boiling water. 182 Materia Medica. Properties and Uses.—Maidenhair is refrigerant, expectorant, tonic, and sub-astringent. In decoction it forms an elegant refrigerant drink in febrile diseases, and in erysipelas, and is also beneficial in coughs, chro- nic catarrh, hoarseness, influenza, asthma, etc. It is likewise reputed efficacious in pleurisy, and in jaundice. The decoction or syrup may be used freely. This plant is highly valued by some practitioners, and deserves investigation. Off. Prep.—Decoctum Adiantum ; Infusum Adiantum. ^ESCULUS HIPPO CASTANUM.

Description.—The ^Esculus Hippocastanum is a beautiful and lofty tree, with numerous, spreading branches, covered with a rough, brown bark. The wood is white and soft, and is very liable to decay. The leaves are large, on long footstalks, and are composed of seven leaflets arising from a common center, the middle one being the largest; they are of a spathulate form, acuminate, serrate, much varied, and of a bright-green color. The flowers are in thyrsoid racemes or panicles, at the extremity of the branches. Calyx pale-green, five-toothed, and spreading. The corolla is formed of five petals, which are irregular, unequal, spreading, inserted into the calyx by narrow claws, waved at the edges, of a white color, marked below with a yellowish-red spot. The stamens are seven, with awl-shaped filaments, supporting reddish, oblong, double anthers. The ovary is roundish, and furnished with a short style and pointed stigma. The fruit is prickly, coriaceous, round- ish, three-celled, and usually containing two seeds, which are exalbumi- nous, with a brown, shining testa, and a large, paler hilum. History.—This plant is a native of Asia, and was introduced into Europe and this country, about the middle of the sixteenth century. It is of rapid growth, flowers in May and June, and ripens its fruit late in autumn. The bark has little odor, and an astringent, bitter, not disa- greeable taste. It contains tannin. The jEscuIus Glabra, or Buckeye, common to Ohio, and other West- ern States, is said to be useful as a substitute for the ^Esculus Hippocas- tanum. Properties and Uses. — Horse-chestnut Bark is tonic, astringent, febrifuge, narcotic, and antiseptic. It has been found very efficacious in Agaric. 183 the treatment of intermittent fever, given in doses of from half an ounce to an ounce of the bark, in the course of twenty-four hours. It is infe- rior, however, to cinchona. Ten grains of the powder of the rind of the nuts, have been found equivalent, in narcotic power, to three grains of opium. A strong decoction of the bark has been recommended as a lotion to gangrenous ulcers. The powdered kernel of the fruit produces sneezing, and has been used as a sternutatory in complaints of the head and eyes. AGARIC. Touchwood. Spunk. Tinder. Nat. Ord.—Fungales, or Fungaceae. Sex. Syst.—Cryptogamia Fungi. History.—This is the product of different species of a genus of mush- rooms, denominated Boletus. The Boletus Laricis which grows upon the larch of the old world, is the white agaric, or purging agaric of medi- cal writers. It is of various sizes, from that of the fist, to that of a child's head, is hard, spongy, brownish or reddish externally, and inter- nally of a light, white, spongy, somewhat farinaceous, friable mass, which, though capable of being rubbed into powder upon a sieve, is not easily pulverized in the ordinary mode, as it flattens under the pestle. It has a sweetish, very bitter taste. The Boletus ignarius, or agaric of the oak, is compared in shape to the horse's hoof. Its diameter is from six to ten inches when young, it is soft like velvet, but subsequently becomes hard and ligneous. On the upper surface, it is smooth, but marked with circular ridges of different colors, more or less brown or blackish ; on the under, it is whitish or yellowish, and full of small pores; internally it is tough and fibrous, and of a tawny-brown color. It is composed of short tubular fibers compactly arranged in layers, one of which is added every year. It has neither taste nor smell. The best is that which grows on the oak, and collected in August or September. It is prepared for use by removing the exterior rind or bark, cutting the inner part into thin slices, and beating these with a hammer until they become soft, pliable, and easily torn by the fingers. Properties and Uses.—The White Agaric has been found useful in checking the night-sweats of phthisis, and other diseases, in the dose of eight grains, and gradually increased to a drachm during the day, and produces no inconvenience to the digestive functions. It is said to act as a cathartic with some persons, in doses of from six to thirty grains. The agaric of the oak, is principally used for arresting hemorrhage from wounds, leech-bites, etc., it is immediately applied to the part with 184 Materia Medica. pressure, and acts probably mechanically, by absorbing the blood and causing it to coagulate. In severe cases it is not to be relied upon. It has sometimes been applied to the purposes of moxa. Steeped in a solution of nitre, and dried, it becomes very inflammable, and is used as a tinder under the name of Spunk or Punk. AGAVE VIRGINICA. False Aloe. Nat. Ord. Amaryllidaceas. Sex. Syst.

The leaves are linear- lanceolate, fleshy, glabrous, radical, with cartilaginous serratures on the margin. The scape is simple, glabrous, with leaf-like scales and sessile flowers, terete, and from three to six feet in hight. The flowers are scattered in a loose, wand-like spike, very fragrant, greenish-yellow, with the tube longer than the acute segments. The corolla is erect, superior, tubular or funnel-form ; filaments erect, longer than the corolla; anthers introrse. Capsule roundish, obscurely triangular, three-furrowed, three-valved, three-celled, and many-seeded. History.—This plant is common to Pennsylvania and the Southern States, growing on dry or rocky banks, and flowering in August and September. In South Carolina, it is known by the name of Rattlesnake's Master, and is considered an antidote to the bite of that reptile. The root is the part used, it is very bitter, and yields its properties to alcohol. Properties and Uses.—False aloe is reputed laxative and carminative, and has been beneficially employed in flatulent colic, and in obstinate diarrhea. It is also said to be a valuable counter-poison to the bites of snakes. The Agave Americana, or American Aloe, also called American Agave, and Century Plant, is an evergreen succulent plant, growing in Florida, Mexico, and other parts of tropical America; it bears a strong resem- blance to the plants of the genus Aloe, with which it is sometimes con- founded. The root and leaves when cut furnish a saccharine juice, which may be converted into syrup or sugar by evaporation, and into a vinous liquor by fermentation. When evaporated to the con- sistence of a soft extract, it forms a lather with water, and is sometimes employed as a substitute for soap. The fresh juice is said to be diuretic, laxative, and emmenagogue. G. Perrin, M. D., of U. S. A., strongly Ajuga Cham.epitys — Agrimonia Eupatoria. 185 recommends the juice of the Am. Aloe, as a remedy in scorbutus, superior to all others. The juice is prepared by cutting the leaves off close to the root, then placing them in hot ashes until thoroughly cooked, when they are removed, and the juice expressed and strained. It is not dis- agreeable to take, agrees with the stomach and bowels and may be given in doses of from one to three ounces daily. AJUGA CHAM.EPITYS. Ground Pine. Nat. Ord.—Lamiaceas. Sex. Syst.—Didynamia Gymnospermia. THE LEAVES. Description.—Ground-Pine has an annual diffused stem, with three- cleft leaves; and the flowers solitary and axillary, shorter than the leaves. Corolla with the upper lip minute and two-toothed. Stamens longer than the upper lip ; anthers all reniform, one-celled. History.—This is a low-creeping plant, a native of Europe, but found also in some parts of the United States, and known sometimes under the names of Bugle or Germander. The leaves, which are the parts used, bear some resemblance to those of the pine in shape, and possess a strong, peculiar, resinous, not disagreeable odor, and a bitter, balsamic taste. By distillation with water, they yield a small proportion of vola- tile oil, resembling that of turpentine. Their virtues are imparted to diluted alcohol. Properties and Uses.—Ground-pine is stimulant, tonic, diuretic, and aperient; it has been successfully employed in palsy, gout, rheumatism, and amenorrhea. It is said to be especially useful in uterine diseases, and paralytic disorders ; also in dropsy, jaundice, strangury, and all visceral obstructions. Externally, the decoction forms an excellent wash for old and indolent ulcers. Dose of the leaves in powder, one or two drachms; but the vinous infusion is considered the best preparation ; its dose is from half a fluidrachm to two fluidrachms. AGRIMONIA EUPATORIA. Agrimony. Nat. Ord.—Rosaceas. Sex. Syst.—Icosandria Digynia. THE ROOT AND LEAVES. Description.—Agrimony is a perennial herb, with a reddish, tapering, not creeping root, branched at the summit. The stems are from one to 186 Materia Medica. three feet in hight, leafy, scarcely branched, and covered with soft, silky hairs. The leaves are alternate, nearly smooth beneath, interrupt- edly pinnate, and consist of three, five, or seven oblong-obovate, or oval- lanceolate leaflets, from one to three inches long, and about one-third as wide, sessile, coarsely serrated, almost glabrous, with various minute intermediate ones; the terminal leaflet with a short petiolule. Stipules of the upper leaves, large, rounded, dentate or palmate. Flowers very numerous, subsessile, yellow, in a dense tapering spike, with lobed bracts; they are about four lines in diameter. Racemes six to twelve inches long, spicate. Petals five, rarely twice the length of the calyx. Calyx inferior, five-cleft, invested with an outer lobed one ; calyx-tube curiously fluted with ten ribs, and surmounted with reddish-hooked bristles. Stamens twelve ; carpels two ; fruit hispid. History.—Agrimony inhabits Asia, Europe, and North America. In this country it is found in fields, on the borders of woods, and along the roadsides, bearing a yellow flower in July and August. It is some- times known by the name of Cockle-burr, Stickwort, etc. It has an agree- able aromatic odor, which is strongest in the flowers, and a rough, bitterish, aromatic taste, which is more powerful in the root. It yields its properties to water. Properties and Uses.—Agrimony is a mild tonic, alterative and astrin- gent. A decoction of it is highly recommended in bowel-complaints, passive hemorrhages, gonorrhea, leucorrhea, and chronic affections of the mucous membranes ; likewise in jaundice, and visceral obstructions, and as an alterative in cutaneous diseases. A strong decoction, sweetened with honey, is reputed an invariable cure for scrofula, if its use be per- sisted in for a length of time; and it has also been highly extolled in the treatment of gravel, asthma, coughs, and obstructed menstruation. Dr. D. C. Payne speaks highly of a continued use of a decoction of this plant in the treatment of erysipelas, and scrofulous affections, to be used freely in connection with diet and regularity of the bowels. As a gargle, the decoction is useful in ulcerations of the mouth and throat. Dose of the powdered leaves, one or two drachms ; of the decoction from one to three fluidounces. The root is very astringent, and may be used wherever this class of agents is indicated. The plant has been also celebrated as a vermifuge. Off. Prep.—Decoctum Agrimoniae ; Infusum Agrimonise. Alcohol. 187 ALCOHOL. Absolute Alcohol.—Hydrate of oxide of Ethyle. Specific gravity, 0.794-6. Spiritus Rectificatus.—Rectified spirit. Specific gravity, 0.835. Alcohol Dilutum.—Proof Spirit. Diluted Alcohol. Specific gra- vity, 0.935. Preparation.—Alcohol is a peculiar liquid, generated for the most part in vegetable juices and infusions, by a fermentation called the vinous or alcoholic. The liquids which have undergone it are called vinous liquors, and are of various kinds; thus, the fermented juice of the grape is called Wine ; of the apple, Cider; the fermented infusion of malt, Beer. This fermentation is owing to the presence of sugar in these liquids, and in other instances, to the conversion of starch into sugar, by some un- known spontaneous change. In vinous liquors, the alcohol is diluted with abundance of water, and associated with coloring matter, volatile oil, extractive, and various acids and salts. In purifying it we take advantage of its volatility, which enables us to separate it by distillation, combined with some of the prin- ciples of the vinous liquors employed, and more or less water. The distilled product of vinous liquors forms the different varieties of ardent spirit of commerce. When obtained from wine, it is called Brandy; from fermented molasses, Rum ; from cider, malted barley, or rye, Whisky ; from malted barley and rye-meal with hops, and rectified from juniper berries, Holland Gin ; from malted barley, rye or potatoes, rec- tified with turpentine, Common Gin ; and from fermented rice, Arrack. These spirits are of different strengths, that is, contain different propor- tionate quantities of alcohol, • and have various peculiarities by which they are distinguished by the palate. Their strength is accurately judged of by the specific gravity, which is always inversely proportion- ate to their concentration. When they have a sp. gr. of 0.920 they are designated in commerce by the term Proof Spirit. If lighter than this, they are said to be above proof; if heavier, below proof. Proof spirit may be considered as corresponding with the average strength of the weaker alcohol used in pharmacy. Proof spirit is still very far from being pure ; being a dilute alcohol, containing about half its weight of water, together with essential oil and other foreign matters. It may be further purified and strengthened by re-distillation, or rectification as it is called. Whisky is the spirit usually employed for this purpose, and from every hundred gallons, between fifty-seven and fifty-eight will be obtained, of the average strength of rectified spirit, (sp. gr. 0.835,) corresponding to the alcohol of the United States' Pharm., and the Spiritus Rectificatus of the London and Dublin 188 Materia Medica. Colleges. When this is once more cautiously distilled, it will be further purified from water, and attain the sp. gr. of about 0.825, which is the lightest spirit which can be obtained by ordinary distillation. It still, however, contains eleven per cent, of water. In the meanwhile, the spirit, by these repeated distillations, becomes more and more freed from essential oil, called Grain, or Fusel Oil. If it be desired to obtain alcohol of still greater concentration, (Abso- lute alcohol), it is necessary to avail ourselves of certain substances which have a powerful affinity for water. Of this nature, are lime, car- bonate of potassa, and chloride of calcium. These, being mixed with the rectified spirit, unite with water and sink, while the purer spirit floats above, and may be separated by decantation or distillation. By availing themselves of substances of this nature, the London and Dublin Colleges are enabled to produce their strongest spirit, which they denomm&teAlcohol. Souberain recommends the following as an easy method for obtaining alcohol free from water, abundantly and economically:—"1st. Rectify alcohol, marking 86° of the centesimal alcoholmeter of Gay-Lussac (rec- tified spirit) by distilling it from carbonate of potassa. This operation raises its strength to 94° or 95°. 2d. Raise this alcohol to 97°, by dis- tilling it with fused chloride of calcium, or by digesting it with quick- lime, from which it must be afterward poured off, in the proportion of a pint of the alcohol to 1^ ounces of the chloride, or 2\ ounces of the lime. 3d. Distil the product of this operation slowly with quicklime, in the proportion of 3| ounces to the pint. The product will be absolute alco- hol. The operation may be shortened to two steps, by distilling the alcohol of 94° or 95°, with an excess of quicklime (7£ ounces to the pint). In all cases, before decanting or distilling, the alcohol must be digested for two or three days with the lime, at a temperature between 95° and 100° F. Lime will not answer as a substance to be distilled from, unless it be in sufficient excess; for otherwise, toward the end of the distillation, the hydrate of lime formed, will yield up its water to the alcohol, and weaken the distilled product." Although freed from water by the processes named, alcohol may still be impregnated with a portion of the essential oil, called grain or fusel oil. This is usually removed by digesting the spirit with charcoal, espe- cially animal charcoal. The same end may be attained on a small scale, by adding a little of the solution of nitrate of silver to the spirit, and exposing it to a bright light. By the action of the oxide of silver on the oil, it is converted into a black powder, and by a new distillation, the spirit is obtained pure. With the exception of alcohol and whisky, but very little pure liquors are to be had in this country, as they are superseded by the domestic articles manufactured by liquor dealers. The following formulae for the manufacturing of domestic liquors, are from an old dealer and manufac- turer. Alcohol. 189 Domestic Gin is made of neutral spirits forty gallons, good Holland gin four gallons, oil of Juniper three ounces, oil of Anise one ounce; mix together. Domestic brandy consists of neutral spirits one gallon, good brandy one pint, molasses, q. s. to color, sweet spirits of nitre eight ounces. History.—Alcohol is a colorless, transparent, volatile liquid, of a penetrating, agreeable odor, and strong burning taste. When free from water of dilution, it is called anhydrous or absolute alcohol, and has the specific gravity of 0.793 at the temperature of 60°. If a piece of anhydrous baryta be dropped into the liquid, if any water be present it will fall to powder ; otherwise, it will not. Alcohol is inflammable, and burns without smoke or residue, the products being water and carbonic acid. When strong, the flame is bluish, but yellowish when weak. It combines with water and ether in all proportions, and is capable of dis- solving a great number of substances, as sulphur, phosphorus, iodine, ammonia, caustic potassa, soda, and lithia ; also the organic vegetable alkalies, urea, tannic acid, sugar, mannite, camphor, resins, balsams, soap, castor oil, and volatile oils ; also most of the chlorides that are readily soluble in water; some nitrates, none of the metallic sulphates, nor the insoluble efflorescent salts. It dissolves fixed oils sparingly, acts on most acids, forming ethers with some, and effecting the solution of others, and dissolves all deliquescent salts, except carbonate of po- tassa. Alcohol is represented by C4 Hi + 2HO—equivalent 46. Properties and Uses.—A powerful, diffusible stimulant, and is the intoxicating ingredient in all malt, spiritous, and vinous liquors. It is never used in its pure state in medicine, but when diluted forms a men- struum for many remedies. In the form of brandy, it is useful in all cases of prostration or sinking, especially in typhus. Brandy is said to be cordial and stomachic; rum, heating and sudorific ; gin and whisky, diuretic. The danger of manufacturing drunkards by the administra- tion of wine or brandy, bitters, cordials, and the like, which was so common a few years since, we are glad to say, has now almost entirely ceased ; and although alcoholic tinctures are sometimes prescribed, yet it is in such small doses, and so well diluted with water, that no fear of intemperance can arise in the mind of the physician. There are very few cases in which alcoholic stimulants are given, and those are never of a chronic character, or in which these fluids have to be used longer than a few days. The discovery of our concentrated preparations, and improved modes of treating disease, have done much to set aside this dangerous and unscientific practice. Externally, alcohol is sometimes applied to produce cold by evapora- tion, or to stimulate where its evaporation is repressed ; and enters into many discutient and stimulating lotions. A mixture of equal parts of white of egg and rectified spirit, is said to be an excellent application 190 Materia Medica. to excoriations from pressure, during their early stage, occurring in pro- tracted diseases. To be applied frequently with a fine brush or feather, and renewed as it dries, until an albuminous coating is formed over the excoriated surface. Alcohol is extensively employed in pharmacy, either rectified or diluted, for the manufacture of tinctures, spirits, ether, essences, resin- ous and alcoholic extracts, and for many other purposes. ALCOHOL AMYLICUM. Amylic Alcohol. Preparation.—Take of the light liquid, which may be obtained at any large distillery, by continuing the distillation for some time after the pure spirit has all been drawn off, any quantity. Introduce it into a small still or retort connected with a condenser, and apply heat so as to cause distillation; as soon as the oil begins to come over unmixed with water, the receiver should be changed, and the distillation being resumed and carried nearly to dryness, the desired product will be obtained. The liquid drawn over during the first part of the distillation will consist of an aqueous fluid, surmounted by a stratum of the Amylic Alcohol. This latter, though impregnated with a minute quantity of water, should be separated and preserved, as being sufficiently pure for use. History.—This oil has various names, as Fusel oil, Grain oil, Corn-spirit oil, Potato-spirit oil, and Hydrated oxide of amyle. It is always present in the products of the alcoholic fermentation, and is an ingredient in the ardent spirit obtained from various kinds of grain, but is most abundant in that procured from fermented potatos. It is present in grain spirit in the proportion of about one part in five hundred by measure. If the whisky procured from grain or potato is distilled to obtain its alcohol, the pure spirit will come over for a certain time, after which, if the dis- tillation be continued, a milky liquid will be obtained, which, upon standing, will be covered with a stratum of this peculiar oil. Subjected to distillation, the milky liquid will at first boil at a comparatively low temperature, and yield water, and a little of the oil; but after a time the boiling point will rise to 269°, when the oil will come over pure. By changing the receiver when the oil begins to distil free from water, the pure oil is collected, separate from the watery part.— U. S. Disp. Fusel oil is a colorless, oily liquid, very mobile, of a strong and nauseous odor which produces stupefying effects, and an acrid, burning, very disagreeable taste. Its vapor when inhaled, causes cough and spasmodic dyspnoea, resembling asthma, often followed by vomiting. As usually prepared its color is pale-yellow. Its specific gravity is Aletris Farinosa. 191 0.818 ; that of its vapor 3.15. It boils at 269°, and at — 4° it crystal- lizes in shining scales. It is soluble in all proportions in alcohol or ether, but is very sparingly so in water. It dissolves iodine, sulphur, and phosphorus, and forms a good solvent for fats, resins, and camphor. It does not leave a greasy stain upon paper, nor take fire by contact with flame, but begins to burn only when heated to about 130°. It consists of ten equivalents of carbon 60, twelve of hydrogen 12, and two of oxygen 16=88. When heated with dry hydrate of potassa it is oxi- dized, two equivalents of hydrogen are given off, and two of oxygen absorbed, and the potassa is found combined with valerianic acid Cio Ho 03. It is generally considered to be a hydrated oxide of amyle, its formula being Cio Hn 0+HO=Ayl O HO. Properties and Uses.—Fusel oil is used in the preparation of valeri- anic acid, valerianate of soda, etc. ALETRIS FARINOSA. Unicorn Root. Nat. Ord.—Liliaceas, Lindley. Haemodoraceaa, Brown.—Sex. Syst. Hex- andria Monogynia. THE ROOT. Description.—Aletris Farinosa, also known by the several names of Star-grass, Colic-root, Ague-root, Crow-corn, etc., has apremorse, perennial root, with radicle leaves, spreading on the ground like a star, sessile, ribbed, broad-lanceolate, entire, smooth, of a pale-green or glaucous color, veined longitudinally, and of unequal size, the largest being about four inches long, and one-fourth as wide. From the center of the leaves arises the scape or flower-stem, which is from one to three feet high, erect, simple, with remote scales or bracts, which sometimes expand into small subulate leaves. Spike slender, scattered, each flower with a short pedicel and a minute bract. Calyx wanting. Perianth white, of an oblong bell-shape, divided in the limb into six acute, spreading segments; the outside, especially as the flower grows old, has a wrinkled, roughish, or mealy appearance. Stamens six, short, inserted near the mouth of the perianth at the base of the segments; ovary three-lobed, pyramidal, tapering, semi-inferior ; style triangular, separable into three. Capsule triangular, invested with the permanent perianth, three-celled, three- valved at top. Seeds numerous, minute, fixed to a central receptacle. History.—Unicorn Root is found in most parts of the United States, usually in dry sandy soils and barrens. Its flowers are white and appear in June and July. The root is the officinal portion, which is small, crooked, blackish externally, brown or Avhitish within, and intensely bitter. Alcohol is its best solvent. (See Helonias Dioica.) 192 Materia Medica. Properties and Uses.—Unicorn Root, in the recent state and in large doses, is considerably narcotic, with emetic and cathartic properties. When dried these properties are destroyed, and it becomes a bitter tonic. It has been used in decoction or tincture, in flatulent colic, hysteria, and to increase the tone of the stomach. It is of much utility in dyspepsia, as well as in cases of general or local debility. But its most valuable property consists in the tonic influence it exerts upon the female genera- tive organs, giving a normal energy to the uterus, and thus proving useful in cases where there is an habitual tendency to miscarriage. In chlorosis, amenorrhea, dysmenorrhea, and engorged conditions of the uterus, as well as in prolapsus of that organ, it is one of our best vegeta- ble agents. The alcoholic extract is an elegant form in which to employ it, in the above affections. In uterine diseases it may be given alone with advantage, or employed in combination with asclepidin, senecin, caulophyllin, or cimicifugin. In flatulent colic and borborygmi, a mix- ture of dioscorein two grains, ginger four grains, and alcoholic extract of aletris two grains, may be divided into two pills, of which one may be given every two or three hours with decided benefit. (See asclepidin). The resinous extract of the root, aletrin, is not so much employed at present, as the alcoholic extract aletridin, although it possesses active properties. Dose of the powdered root, from five to ten grains, three times a day; of the saturated tincture, from five to fifteen drops, in water. Off. Prep.—Extractum Aletridis Alcoholicum. ALISMA PLANTAGO. Water Plantain. Nat. Ord.—Alismaceae. Sex. Syst.—Hexandria Polygynia. the leaves. Description.—This is a perennial, caulescent herb, sometimes called Mad-dog weed. The leaves are radical, oval, oblong or lanceolate, sub- cordate at the base, cuspidate or abruptly acuminate, five to nine- nerved, from four to six inches in length, about two-thirds as wide, and on long radical petioles. The scape is one or two feet high, with whorled panicled branches; the panicles are loose, compound, many- flowered; branches of the panicle with bracts at the base. Carpels fifteen to twenty, obliquely obovate, forming an obtusely-triangular whorl in fruit. The flowers are small, white, whorled, and numerous; petals three, tinged with purple, roundish, deciduous, larger than the green, ovate, persistent sepals. Stamens six; achenia obtusely three- cornered. Root fibrous. Allium Sativum. 193 History.—Water Plantain is common to Europe and the United States, being a smooth, handsome inhabitant of ponds, ditches, streams, etc., flowering in July. At one time the root was in great repute as a cure for hydrophobia, but subsequent experiments have proved it ineffi- cacious. The leaves are the parts used. Properties and Uses.—When the fresh leaves of water-plantain are bruised and applied to the skin, they produce a rubefacient effect, and will even vesicate. When dried and powdered, and taken in the dose of one or two drachms two or three times a day, they have been suc- cessfully employed in gravel and other urinary affections. ALLIUM SATIVUM. Garlic. Nat. Ord.—Liliacea?. Sex. Syst.—Hexandria Monogynia. the bulb. Description.—This is a very extensive genus, including over sixty species. • The Allium Sativum is officinal; it is a perennial plant, bulb- ous. The bulbs are numerous, and inclosed in a common membranous covering, from the base of which the fibers that constitute the proper root descend. The stem is simple, and is about two feet high. The leaves are long, acute, flat, distichous, glaucous, channeled above, sheathing the lower half of the stem. At the termination of the stem is a cluster of flowers and bulbs mingled together, and inclosed in a calyptriform, horned spathe, which opens on one side and withers. Umbels bulbiferous. The flowers, if any, are pink, red, or whitish, rather longer than the stamens and appear in July. Perianth, deeply six-parted, segments mostly spreading, permanent, equal; ovary angu- lar; stigma simple, acute; capsule three-lobed. It is a native of Sicily, but cultivated in various sections of the country. History.—The part employed is the bulb, which is usually dug up, with a portion of the stem attached, and after having been dried in the sun, are tied together in bunches. They lose nine parts in weight by drying, while their sensible properties are but little diminished. They possess a disagreeable, pungent odor, and an acrid, bitter taste, both of which are owing to the presence of an essential oil which is very vola- tile. The oil is of a yellow color, exceedingly pungent odor, and strong acrid taste; is heavier than water, contains sulphur, and irritates or even vesicates the skin when applied to it. Water, alcohol, or vinegar, extract the virtues of garlic. Properties and Uses.—Stimulant, diuretic, expectorant, and rubefa- cient. Used as a medicine, and for culinary purposes. When taken 13 194 Materia Medica. internally, the active principle is speedily absorbed, and, penetrating the system, becomes sensible in the breath and various secretions, and is said to produce the same effects, when applied externally. Taken internally, garlic quickens the circulation, excites the nervous system, promotes expectoration in a debilitated state of the vessels of the lungs, produces diuresis or diaphoresis according as the patient is kept cool or warm, and acts as a tonic and carminative to the stomach. It has been beneficially used in coughs, catarrhs, hooping-cough, hoarseness, worms, and calculous affections during the absence of inflammation. It is very useful in the nervous and spasmodic coughs of children. The juice, given in the dose of a few drops, is said to check nervous vomiting; and mixed with olive or sweet-almond oil, is recommended in atonic deaf- ness. Garlic juice, sweet oil of almonds, and glycerin, of each, equal parts, mixed, and dropped in the ear, has cured several cases of deaf- ness. Externally, the bruised bulbs, applied as a poultice above the pubes, has restored the action of the bladder, in cases of retention of urine, from debility of that organ. In the same shape, it may be applied to the spine and chest of infants in pneumonia; to the feet and legs, as a revulsive, in disorders of the head, and febrile complaints of children; and has been employed as a resolvent in indolent tumors, stimulating the absorbents to action. It may be taken whole, or the juice may be administered mixed with sugar. The dose of the fresh bulb is from half a drachm to two drachms; of the juice, half a drachm. If used too largely, or in excited states of the system, it is apt to produce flatulence, gastric irritation, hemorrhoids, headache, and fever. ALLIUM CEPA. Onion. Nat. Ord.—Liliaceaa. Tribe—Scillese. Sex. Syst.—Hexandria Monogynia. THE BULB. Description.—The onion is a biennial plant, the root bearing a tuni- cated bulb, compressed, or round, or oblong in figure, invested with a shining, thin, dry membrane. The scape, which appears the second year, is from two to four feet high, straight, naked, smooth, stout, fistu- lous, bearing at the top a large, round umbel of greenish-white flowers, and swelling toward its base. The leaves are fistulous, terete, distichous, glaucous, acute, shorter than the stem. Spathe reflexed, generally longer than the lower flowers. Umbels large, regular, compact, many- flowered, not bulbiferous. Pedicels about an inch long, thickened at the point. Stamens nearly twice as long as the perianth. Alnus Rubra. 195 History.—The onion is supposed to be a native of Hungary, but is now found over the whole civilized world. The bulbs are of various shapes and sizes, are composed of concentric fleshy and succulent lay- ers, and according to the variety are reddish, yellowish, or white. They have, in a high degree, the peculiar pungent odor of the plant, with a sweetish and acrid taste. It contains a white acrid volatile oil holding sulphur in solution, albumen, much uncrystallizable sugar and mucilage, phosphoric acid both free and combined with lime, acetic acid, citrate of lime, and lignin. The expressed juice is susceptible of the vinous fermentation. Properties and Uses.—The onion is stimulant, diuretic, expectorant, and rubefacient; used moderately it increases the appetite, and promotes digestion, but in large quantities it is apt to occasion flatulence, gastric uneasiness, and febrile excitement. The juice, mixed with sugar, forms a pleasant syrup, useful in coughs, catarrhs, and croup, to be given in the absence of much inflammatory action. Roasted and split, it is occa- sionally employed as an emollient cataplasm to boils and other suppu- rating tumors. In dropsy and gravel, a saturated tincture made with good gin, has been recommended. Boiling deprives the onion of its essential oil, and it then becomes a mild esculent, much used as food. ALNUS RUBRA. Tag Alder. Nat. Ord.—Betulaceaa. Sex. Syst.—Moncecia Tetrandria. THE BARK. Description.—This plant is the Alnus Serrulata of Aiton and Willde- now, and is known by the names of Smooth Alder, and Common Alder. It is a well-known shrub growing in clumps, and forming thickets on the borders of ponds and rivers, and in swamps. The stems are numerous, rather straight, and from six to fifteen feet in hight. The leaves are obovate, acuminate, dorbly serrulate with minute teeth, thickish, smooth and green on both sides, strongly veined, the veins and their axils being hairy beneath, from two to four inches long, by two-thirds as wide, and on petioles one-half or one-third of an inch long. The sti- pules are elliptical and obtuse. Aments two or three inches long, slender, pendulous, fascicled at the ends of the branches; fertile aments short, thick, dark-brown, persistent, ovoid-oblong, several together a little below the sterile one. Stamens four. Fruit ovate. History.—This shrub blossoms in March and April, bearing flowers of a reddish-green color. The bark is the part used and imparts its properties to boiling water. 196 Materia Medica. Properties and Uses. —Tag Alder Bark is alterative, emetic, and astringent. A decoction or extract of it is useful in scrofula, secondary syphilis, and several forms of cutaneous disease. The inner bark of the root is emetic ; and a decoction of the cones is said to be astringent, and useful in hematuria, and other hemorrhages. An excellent ophthalmic powder is made by boring a hole from half an inch to an inch in diame- ter, lengthwise, through a stout piece of a limb of tag alder. Fill the opening with finely-powdered salt, and close it at each end. Put it into hot ashes, and let it remain till the tag is almost all charred, (three or four days,) then split it open, take out the salt, powder, and keep it in a vial. To use it, blow some of the powder in the eye, through a quill. An article named Alnuine is said to have been obtained from this plant, which possesses alterative, tonic, and astringent properties, and is recom- mended in herpes, syphilis, scorbutus, scrofula, impetigo, etc., in doses of one to three grains, three or four times a day. Likewise an essen- tial agent, Alnuin, for the same purpose. We have not been advised of the manner in which these agents are prepared, and therefore can say but little concerning them. Off.

Description.—The Aloe Spicata, or Spiked Aloe, is a native of South Africa, growing near the Cape of Good Hope, in sandy soil. The stem is woody, round, from three to four feet high, about five inches in diam- eter, and leafy at the summit; the leaves are thick, fleshy, spreading, subverticillate, about two feet long, broad at the base, gradually narrow- ing to the point, channeled or grooved on their upper surface, remotely teethed upon their edges ; their parenchyma almost colorless. Spike a foot long, very compact, with horizontal and campanulate flowers, of a scarlet color, which contain a large quantity of purplish honey juice. Beneath each flower is a broad, ovate, acute bracte, of a white color, with three green streaks, and nearly as long as the corolla. The three inner petals are ovate, obtuse, white, with a triple green line, and broader than the three outer, which otherwise resemble them. The sta- mens are much longer than the perianth. Aloe Socotrina, is said to be a native of the island of Socotra; its stem is erect, woody, a foot and a half high, or more, naked below, where it Aloe Spicata. 197 is strono-ly marked with the scars of former leaves ; the leaves are at the summit of the stem, amplexicaul, green, ascending, ensiform, rather concave on their upper surface, convex beneath, and curved inward at the point, and marked with numerous small, white marginal serratures ; the parenchyma abounding in a bright brownish-yellow juice. Raceme cylindrical, unbranched ; the flowers are scarlet at the base, pale in the center, and greenish at the point. The stamens are unequal, three of them being longer than the corolla. Aloe Vulgaris, is a native of south-eastern Europe, and north Africa, and is cultivated in Italy, Sicily, Malta, and the West Indies. It has a short, simple, cylindrical and woody stem ; the leaves being fleshy, am- plexicaul, first spreading, then ascending, lanceolate, glaucous-green, a little mottled with darker spots, flat on the upper surface, convex beneath, and armed with hard reddish spines, distant from each other, and perpendicular to the margin; the parenchyma is slightly colored brown, and very distinct from the tough leathery cuticle. The scape is axillary, glaucous-reddish, branched; spike cylindrical-ovate. The flowers at first erect, then spreading, afterward pendulous, yellow and not longer than the stamens. The juice obtained by expression from the parenchyma is mucilagi- nous, and possesses but little medicinal virtue; the proper aloetic juice is obtained from the inter-cellular passages found between the longitu- dinal vessels which are situated beneath the epidermis of the leaves, and which juice may be readily obtained by cutting these in a transverse direction. History.—There are several species of Aloe, from which the officinal drug is obtained—the A. Spicata, A. Socotrina, A. Vulgaris, etc., which grow in various parts of the world, the first at the Cape of Good Hope, furnishing the Cape Aloes ; the second in the island of Socotra, from whence is taken the Socotrine Aloes; and the third, in the East and West Indies, Italy, Spain, Barbary coast, etc., which furnish the Barbadoes Aloes. Cape Aloes, when freshly broken, has a very dark olive or greenish color, approaching to black, with a smooth, bright surface, and translu- cent edges. The powder is of a fine greenish-yellow color. It has a strong, disagreeable, but not nauseous odor, and a peculiar bitter taste. It is sometimes confounded with the Socotrine Aloes, especially the finer sorts. Socotrine Aloes, is in pieces of a yellowish, or reddish- brown color ; its interior surface lighter than its exterior, but rendered darker by exposure to the air. Its surface is somewhat glossy, and its fracture smooth and conchoidal, with sharp, semi-transparent edges. Its powder is bright-yellow. The odor is peculiar, not unpleasant, with a bitter, disagreeable, but aromatic taste. It is the best article for medi- cinal purposes. Barbadoes Aloes, is very little used, except in veteri- 198 Materia Medica. nary practice. Beside these, we have several other varieties, useless to name here. Aloes yields its active matter to cold water, and when good, is almost wholly dissolved by boiling water ; but the inert portion, or apothime of Berzelius, is deposited as the solution cools. It is also soluble in alco- hol, rectified or diluted. Long boiling impairs its purgative properties, by converting the aloesin into insoluble apothtme. The alkalies, their carbonates, and soap, alter, in some measure, its chemical nature, and render it of easier solution. It is inflammable, swelling up and decrepi- tating when it burns, and giving out a thick smoke which has the odor of the drug. Those substances only are incompatible with aloes, which alter or precipitate the aloesin, as the insoluble portion is without action upon the system. Its aqueous solution keeps a long time, even for several months, without exhibiting moldiness or putrescency; but it becomes ropy, and acquires the character, which it did not previously pos- sess, of affording an abundant precipitate with the infusion of galls. Analysis has detected in aloes, 85 parts in 100 of bitter extractive, called aloesin, 2 of ulmate of potassa, 2 of sulphate of lime, 0.25 of gallic acid, 8 of albumen, and traces of carbonates of potassa and lime, and phosphate of lime. Properties and Uses.—Tonic, purgative, emmenagogue, and anthel- mintic. In doses of from half a grain to a grain, two or three times a day, it exerts a decided tonic influence, but is seldom resorted to for this purpose. As a laxative and purgative, its applications are unbounded ; it acts more especially on the muscular coat of the large intestines, rather increasing their peristaltic motion, than effecting copious thin or watery discharges ; and from its tendency to irritate the rectum, especially when frequently repeated, it is apt to give rise to hemorrhoids, or aggra- vate them when already existing. When applied endermically to an ulcer or blistered surface, it purges as effectually and promptly as when taken into the stomach ; ten grains used thus, will purge in from six to ten hours. It is commonly supposed to have no action on the jejunum or ileum; and some imagine it to influence the duodenum, and especially the mouths of the biliary ducts, causing an increased flow of bile; stim- ulating the intestinal canal, when that secretion is suspended as in jaun- dice. Its emmenagogue influence is attributed by some to a sympathetic extension of this irritation from the rectum to the uterus ; but there is no doubt that it exerts a direct influence on this organ, independent of the intestinal irritability. It is said that one to three grains of extract of hyoscyamus, or hops, or two grains of ipecacuanha, mixed with the aloetic dose, will prevent its irritating effect on the lower intestines. An increase of the quantity of aloes beyond the medium dose, is not attended by a corresponding increase of effect. Aloes has been efficacious in constipation, dyspepsia, and ascarides ; in this last instance, being used Aloesin. 199 in form of injection, ten grains to three ounces of water, for children. In chlorosis and amenorrhea it has often proved serviceable, and is used for this purpose, in various combinations. In cases of delicate females, with loss of appetite, torpor of the bowels, and suffering with suppres- sion of the menses, the following has been recommended for the pur- pose of exciting proper ovarian or uterine action: Take of best aloes, pulverized, asafcetida, pulverized, of each, half a drachm, cantharides, pulverized, twenty grains; mix and rub well together with a little soap, and divide into twenty pills. Of these give from one to three, three times a day. If the patient be very feeble, some of the salts of iron may also be added. Injections of aloes, composed of from ten to thirty grains dissolved in two or three fluidounces of water, and thrown up the rectum daily, and continued for a week previous to the menstrual period, have sometimes proved effectual. Aloes should never be given in inflammatory diseases, in irritable, plethoric habits, in gastritis, enteritis, where piles are present, to females liable to sudden uterine evacuations, nor during pregnancy. In hemor- rhoids it may be given when modified by combination. Soap, or an alkaline carbonate, lessens its irritant action. The union of other purga- tives with aloes, often modifies its tendency to irritate the rectum. One grain of aloes with two or three grains of sulphate of iron, will also modify this action, and will produce as much effect as two or three grains of aloes. As a cathartic, aloes will be found useful in habitual constipa- tion from intestinal torpor, jaundice, scrofula, hypochondriasis, and where there is a tendency to cerebral congestion. Dose of aloes, is from two to ten, or even twenty grains; and the most convenient form of admin- istration is that of pill. It enters as a constituent into a great number of useful compound remedies.

Bitter Extractive of Aloes. Preparation.—Exhaust powdered Aloes with cold water; evaporate the infusion one-half; add an excess of acetate of lead, which precipitates the gallate, ulmate and albuminate of that metal; pour into the clear liquor solution of ammonia, which gives a yellowish-orange colored pre- cipitate, consisting of oxide of lead combined with Aloesin, and which must be separated and washed with boiling water, and then decomposed 200 Materia Medica. by a current of sulphureted hydrogen, but out of contact with atmos- pheric air. Sulphuret of lead is deposited, and a colorless liquid floats above it, which must be decanted, and evaporated in vacuo. History.—Thus prepared, Aloesin is in colorless, or pale-yellow scales, like a varnish, without any sign of crystallization, of a powerful aloetic taste, soluble in cold water, alcohol, and especially weak spirit, sparing- ly soluble in ether, and not at all in fixed or volatile oils. Its aqueous solution, when exposed to the air, owing to oxidation, becomes dark-red; it is not precipitated by iron salts, acetate of lead, isinglass solution, or infusion of galls. Heat, exposure, and moisture convert it into an in- soluble, inert oxygenated extract. Properties and Uses.—Same as aloes. Eight grains of aloesin being equal to ten of Socotrine, and fifty of Cape aloes. ALOINE. The Purgative Principle of Barbadoes Aloes. Preparation.—Pulverize the aloes with sand, and then treat it with cold water ; strain off the liquid, and evaporate it in vacuo to a syrupy consistence—set it aside for a few days, when it will be filled with a mass of brownish-yellow granular crystals. This is impure Aloine. To remove the brown matter associated with it, re-crystallize it repeated- ly from warm water, until the crystals are of a sulphur-yellow. In making these solutions, the temperature of the water should not exceed 150° F. At 212° Aloine oxidizes rapidly, and is decomposed. History.—When pure, it crystallizes in stellated groups of small pris- matic needles, whose purity is shown by the color, which should not deepen by exposure to the air in desiccation. It is completely neutral, sparingly soluble in cold water, but readily in warm, with a taste, at first sweetish, but soon becoming intensely bitter. Its solutions in the alkalies and their carbonates is of an orange-yellow, and the liquid absorbs oxygen upon contact with the atmosphere, which rapidly deepens its color. Boiled with alkalies or acids, it is speedily transformed into a brown resin. Corrosive sublimate, nitrate of silver, or neutral acetate of lead, do not cause its precipitation ; concentrated subacetate of lead produces a precipitate of an intense yellow, soluble in excess of water, and becoming deeper colored on exposure. Cold fuming nitric acid dis- solves it, without disengaging gas, forming a reddish-brown liquid ; to which, if sulphuric acid be added in great excess, a yellow pulverulent body is thrown down, which explodes when heated. By dry distillation, aloine furnishes a slightly aromatic, volatile oil, and a quantity of resin- ous substance. It forms crystallized compounds with bromine, but not Alpinia Cardamomum. 201 with chlorine, although it combines equally well with this latter. Bro- mine, added to a cold aqueous solution of aloine, instantly forms a yellow precipitate, while the supernatant liquid assumes a very acid reaction, consequent upon the formation of hydrobromic acid. By dissolving the precipitate in warm alcohol, and cooling the solution, bromated aloine is obtained in brilliant yellow needles, grouped in stars. Properties and Uses.—Same as aloes. Dose of alo'ine, one-fourth of a grain to a grain. ALPINIA CARDAMOMUM. Cardamom. Nat. Ord.—Zingiberaceae, Lindley. Scitamineas, Brown. Sex. Syst.— Monandria Monogynia. THE FRUIT. CARDAMOM SEED. Description.—Alpinia Cardamomum has a tuberous horizontal root or rhizoma, with numerous fleshy fibers, and sending up from eight to twenty erect, simple, smooth, jointed, green and shining, perennial stems, which rise from six to ten feet in hight, and bear alternate, spongy, sheathing, leaves. The leaves are bifarious, subsessile on their sheaths, elliptical-lanceolate, fine-pointed, somewhat villous above, sericeous un- derneath, entire, with strong midribs, and short footstalks, from one to two feet long, and from one to five inches broad. The shecdhs are slightly villous, with a rounded ligula rising above the mouth. There are from three to five scapes proceeding from the base of the stem, which are from one to two feet long, lying upon the ground, flexuose and jointed; the branches or racemes alternate, one from each joint of the scape, sub-erect, and two or three inches long. Bracts soli- tary, oblong, smooth, membranous, striated, sheathing, one at each joint of the scape. Flowers alternate, short-stalked, solitary at each joint of the racemes, opening in succession as the racemes lengthen. Calyx monophyllous, funnel-shaped, three-toothed at the mouth, about three quarters of an inch long, striated with fine veins, permanent. Tube of corolla slender, as long as the calyx ; limb double, exterior of three, oblong, concave, nearly equal, pale greenish-white divisions; inner-lip obovate, much longer than the exterior divisions, somewhat curled at the edge, with the apex slightly three-lobed, marked chiefly in the center with purple violet stripes. Filament short, erect. Anther double, emarginate. Ovary oval, smooth. Style slender. Stigma funnel- shaped. Capsule oval, somewhat three-sided, size of a small nut- meg, three-celled, and three-valved; seeds pale-brown, coriaceous, nu- merous. 202 Materia Medica. History.—This plant is a native of the mountains of Malabar, grow- ing spontaneously in the forests after the removal of the undergrowth. The fruit, which is the officinal part, is not obtained until at the end of the fourth year; it is a three-celled capsule, containing numerous seeds. The seeds constitute about 74 parts by weight in the hundred of the fruit or capsules received in commerce. They are small, irregular, an- gular, rough, of a brown color, and are easily pulverized ; their odor is fragrant, and their taste warm, slightly pungent, and highly aromatic. The capsules are from three to nine lines long, three-sided with rounded angles, ovate-oblong, of a yellowish-white color, and three or four lines in thickness ; they are commonly rejected, although they are slightly aromatic. Water or alcohol extracts the virtues of the seed, which con- tain a volatile oil, of an agreeable, penetrating odor, and a strong aromatic, camphoraceous, slightly bitter taste. Its specific gravity is 0.945. It undergoes a change, soon becoming deprived of its odor and taste. The oil obtained by percolation of ether through the powdered seeds, and evaporation of the ether, is of a light greenish-brown color, consists of volatile and fixed oils, and keeps better than the oil procured by distillation. The seeds should be allowed to remain in the capsules until wanted, as by this means their aromatic properties are the best preserved. Properties and Uses.—Cardamom seeds are aromatic, stomachic, and carminative, chiefly used in flatulency, and as an adjuvant or corrective in compound preparations. Dose from ten grains to two drachms. Off. Prep. — Syrupus Stillingiae Compositus; Tinctura Cardamomi; Tinctura Cardamomi Composita. ALTHAEA OFFICINALIS. Marsh-Mallow. Nat. Ord.—Malvaceas. Sex. Syst.—Monadelphia Polyandria. THE ROOT. Description. — Althaea officinalis is a herbaceous, perennial, hoary green herb, peculiarly soft and downy, with fine starry pubescence, and having a tap-shaped, rather woody, perpendicular branching root. The stems are several, erect, from two to five feet in hight, simple, round, branched and leafy toward the summit, and tough and pliant. The leaves are alternate, petiolate, nearly cordate at the base, oblong-ovate and obscurely three to five-lobed above, various in breadth, plaited, five- ribbed, unequally serrated, somewhat angular, soft and pliable, and clothed on both sides with a soft velvety down. The flowers are termi- nal, in very short, dense axillary panicles, rarely solitary, and of a deli- cate, uniform, blush color. The coi'dlla has five spreading, obcordate Althaea Officinalis. 203 petals, of a pale-purplish color ; the fruit consists of numerous capsules united in a compact circular form, each containing a single seed. History.—This plant grows in salt marshes and wet situations in many parts of Europe, and has been cultivated in several parts of this country. It flowers from July to September. Our shops are supplied nearly ex- clusively from Europe. The whole plant abounds in mucilage. The root is in pieces of three, four or more inches in length, round, nearly as thick as the finger, sometimes split, white, downy, with a peculiar faint smell, a mild, mucilaginous, sweetish taste, and a short, somewhat fibrous fracture. It contains a large proportion of mucilage, which is extracted by cold or hot water, and the solution decomposes if allowed to stand any great length of time. Those pieces which are plump and but slightly fibrous should be preferred, while those should be rejected which are woody, moldy, discolored, of a sour or musty smell, or of a sourish taste. The Hibiscus Palustris, (or H Moscheutos) Marsh Hibiscus, of this country, has a root very much resembling that of the Marsh-mallow, possesses exactly the same properties, and may be as effectually used. It is a tall, showy, perennial plant, growing in salt marshes, near salt springs, and on wet prairies, and flowers in August. The stem is sim- ple, erect, herbaceous, round, downy, and from four to six feet in hight. The leaves are from four to six inches, by three to four inches, often with two lateral lobes, ovate, obtusely dentate, and hoary-toraento&e beneath. The flowers are larger than those of the hollyhock, rose-col- ored, purple in the center. Peduncles long, axillary, or connected with the petiole, usually distinct from it, but sometimes united with it, and jointed above the middle. Styles one inch longer than the stamens. Properties and Uses.—The roots of each of the above plants are demulcent and diuretic, and may be used indiscriminately, the one for the other. They will be found valuable, in the form of decoction, in diseases of the mucous membranes, as hoarseness, catarrh, pneumonia, gonorrhea, vesical catarrh, renal irritation, acute dysentery and diarrhea. In strangury, inflammation of the bladder, hematuria, retention of urine, some forms of gravel, and indeed in nearly every affection of the kidney and bladder, their use will be found advantageous. I make much use of them combined with equal parts of spearmint, in urinary derange- ments. They are likewise efficacious in gastro-intestinal irritation and inflammation. Externally, they are very useful in the form of poultice, to discuss painful inflammatory tumors, and swellings of every kind, whether the consequence of wounds, bruises, burns, scalds, or poisons; and have, when thus applied, a happy effect in preventing the occurrence of gangrene. As a mucilaginous demulcent only, the Althaea Rosea, or hollyhock may be substituted. Off. Prep.—Decoctum Altheeee ; Infusum Althaeae. 204 Materia Medica. ALUMEN. Alum. Sulphate of Alumina and Potassa. History.—Officinal Alum is a double salt, consisting of the tersulphate of alumina, united with sulphate of potassa. It is occasionally manu- factured from earths which contain it ready formed, but most generally from minerals called Alum Ores, the principal of which is the alum-stone. This is calcined and exposed to the air for three months, being frequently sprinkled with water, in order to soften it. Then it is lixiviated, and crystallized by evaporation. Alum is a white, slightly efflorescent salt, crystallized in regular octo- hedrons, with a sweetish astringent taste. It dissolves in fourteen or fifteen times its weight of cold water, and three-fourths of its weight of boiling. It reddens litmus. When heated above 212°, it undergoes the aqueous fusion ; and if the heat be continued, it loses its water, swells up, becomes a white, opaque, porous mass, and is converted into the officinal preparation called Dried Alum, (Ah/men Exsiccatum). It is incompatible with the alkalies and their carbonates, lime and lime- water, magnesia and its carbonates, tartrate of potassa, and acetate of lead. Its specific gravity is 1.71. Properties and Uses.—In ordinary doses of ten to twenty grains every three or four hours, in solution, syrup or molasses, it is astringent and antispasmodic. In larger doses of thirty to sixty grains every three or four hours, it is purgative, and every ten or fifteen minutes, emetic. As an astringent, it is used in passive hemorrhages, colliquative sweats, diarrhea attending typhoid fever, diabetes and chronic diarrhea and dysentery. Also, in gleet and leucorrhea, and by some during the inflammatory stage of gonorrhea, in solution with an infusion of marsh- mallow. In colica pictonum it has been highly extolled as a purgative; and is recommended as an emetic in pseudo-membranous croup. As an antispasmodic, it has been found useful in hooping-cough. In various anginose affections it has been successfully applied locally, in powder or solution, also as a gargle in sore-throat and relaxation of the uvula, as a wash for ptyalism, and as an injection in gleet and leucorrhea, alone or conjoined with sulphate of zinc. It has likewise proved very useful in purulent ophthalmia of infants, and in the latter stages of conjunctival inflammation. In colica pictonum it may be given in doses of from thirty to sixty grains, every three hours ; in this disease it allays nausea and vomiting, relieves pain and flatulence, and opens the bowels with more certainty than any other medicine. It is frequently applied as a local styptic either in powder or solution, in epistaxis, menorrhagia, and to check the bleeding from cut surfaces ; it may be applied on lint, or on a small piece of sponge if used in solution. From four to ten grains of alum to the ounce of water, is of sufficient strength for a collyrium. Amaranthus Hypochondriacus. 205 I have found much advantage from the use of the following preparation in troublesome cough, especially when attended with tickling or irritation of the fauces, larynx, etc.:—Take of a saturated solution of alum, syrup of balsam of Tolu, each two fluidounces, camphorated tincture of opium one fluidounce ; mix. The dose for an adult is a tablespoonful three or four times a day, or whenever the cough is very troublesome. Several practitioners to whom I have recommended the preparation, have found it very efficacious. Alumen Exsiccatum.—Dried or Burnt Alum, sometimes called Alu- men Ustum, is prepared by heating alum, until ebullition ceases, and it becomes dry. It is principally used as a mild escharotic, to destroy fun- gous flesh. It differs from alum only in the absence of water. Alum Whey, is made by boiling two or three drachms of powdered alum in a pint of milk, and then straining off the thin liquor. It may be given internally, in diarrheas, etc., in doses of from half an ounce to one or two ounces. Externally, applied over the eye as a poultice, it is very serviceable in inflammations of that organ. Off. Prep.—Alumen Exsiccatum ; Cataplasma Aluminis; Lotio Zinci Compositum; Pulvis Stypticus.

Description.—Amaranthus Hypochondriacus is an annual herb, with a stout, upright stem, and growing from three to four feet high. The leaves are oblong, lanceolate, mucronate, green with a red-purple spot, or tinged with purple; flowers clustered in racemes, and of a bright-red purple, as well as the awl-shaped bracts. Racemes pentandrous, com- pound, erect, compact. Stamens five. The whole plant is dark-red, or reddish-purple, with long plume-like clusters. History.—This plant, also known by the names of Fiances' Feather, Lovely Bleeding, Red Cocks-comb, etc., is a native of the Middle States, and is cultivated as an ornamental plant in gardens. It bears deep bright- red flowers in August. The leaves, which are the parts used, are also red, and yield their virtues to water. Properties and Uses.—Amaranth is astringent. The decoction drank freely is highly recommended in severe menorrhagia, and has also been found beneficial in diarrhea, dysentery, and hemorrhage from the 206 Materia Medica. bowels. It has likewise been used as a local application in ulceration of the mouth and throat, in leucorrhea, and as a wash to foul, indolent ulcers. AMBROSIA TRIFIDA. Tall Ambrosia. Nat. Ord— Asteraceaa. Sex. Syst—Moncecia Pentandria. THE LEAVES. Description. — Ambrosia Trifida is variously known by the names Horseweed, Bitter-weed, Great Rag-weed, Horse-cane, Rich-weed, etc. It is a rough, hairy, herbaceous, annual plant, with an erect, branching, fur- rowed stem, from five to ten feet in hight. The leaves are opposite, from four to seven inches broad, scabrous and hairy, with three large, deep lobes which are oval, lanceolate, acuminate and closely serrated; the lower leaves are often five-lobed. Petioles narrowly-winged, ciliate; racemes often paniculate. Flowers mean and obscure, in long leafless spikes, axillary and terminal. Fruit (fertile involucre) turbinate- obovoid, with a short conical pointed apex, six-ribbed, the ribs terminat- ing in as many cristate tubercles. History.—This plant grows in low grounds and along streams, from Canada to Georgia, and west to Louisiana and Arkansas, bearing green- ish-yellow flowers in August. It is much in use among farmers, for the "slabbers" in horses, effecting a cure in a few hours. It has a spicy, pleasant, aromatic taste, slightly resembling ginger, and imparts its pro- perties to water. Properties and Uses.—This plant is slightly stimulant, astringent, and antiseptic. Useful in decoction as an injection in leucorrhea, prolapsus uteri, chronic gonorrhea, and gleet; also valuable as a collyrium, in ophthalmia, and as a wash or gargle—with its internal use also—in the sore mouth of nurses. It will be found an excellent application to mer- curial, and all other ulcers of a fetid or gangrenous character. As a remedy for mercurial salivation, used every half hour as a wash, it is said to he prompt and efficacious. Internally, the decoction is useful in fevers, attended with a disposition to putrescency, diarrhea, and dysen- tery. Dose of the decoction from one to two ounces. Two preparations are said to have been obtained from this plant, called Ambrosine and Elatine. The former, it is stated, is found associated with elatine, and forms beautiful and brilliant, pearl-like, prismatic crystals with sulphuric acid; it is tasteless and inodorous, and can be retained on the most sensitive stomach. It is recommended as a tonic, diuretic, and altera- tive in dropsical affections with great loss of vitality; in nephritis and Ammoniacum. 207 albuminuria; likewise in diabetes, consumption, scrofula, etc. Dose, one to three grains, three to six times a day. If this agent is as effec- tual as its manufacturers state, it will become one of the most valuable in the Materia Medica.—Elatine is obtained in the form of a white, floc- culent precipitate. Properties and dose similar to ambrosine. We have not been able to learn the mode of preparing these articles. The Ambrosia Artemisi^efolia (A. Elatior), Roman Wormwood, or Rag-weed, has a slender stem, rising from one to three feet high, much branched, and pubescent when young; the leaves are opposite, and the upper alternate, twice pinnatifid, smoothish above, paler or hoary beneath; barren flowers small, green, in terminal racemes, or spikes loosely panicled; the fertile ones sessile about the axils of the upper leaves; fruit obovoid, or globular, pointed, armed with about six short acute teeth or spines. It is sometimes called Hog-weed. It is very com- mon in all our fields, and would probably prove fully as efficacious, if not more so than the A. Triflda. It is highly recommended as a fomen- tation in recent inflammation from wounds or injuries of any kind. Made into a salve by bruising the green leaves, and simmering them in spirits and cream, it is very useful in hemorrhoidal tumors, and some forms of ulcer. AMMONIACUM. Gum Ammoniac. Nat. Ord.—Apiaceaa. Sex. Syst. Pentandria Digynia. the concrete juice of dorema ammoniacum. Description.—The Dorema Ammoniacum has a large, perennial root, with stems rising from seven to ten feet high, about four inches in cir- cumference at the base, clothed with a glandular down, smooth, glaucous, resembling Opoponax. The leaves are large, petiolate, somewhat two- pinnate. Pinnae in three pairs, each pair somewhat remote. Leaflets inciso-pinnatifid, with oblong, mucronulate, entire, or slightly-lobed segments, coriaceous. Petiole downy, very large, and sheathing at the base. Umbels proliferous, racemose; partial umbels globose, on short stalks, often arranged in a spiked manner. General and partial involucre wanting. Flowers sessile, immersed in wool. Petals white, ovate, reflexed at the point. Margin of calyx with five minute, acute, mem- branous teeth. Disk large, fleshy, cupshaped. Stamens and styles yellow, the latter complanate, recurved at apex. Stigmas truncate. Ovary very woolly. Fruit elliptical, compressed, with a broad flat edge; mericarps with three distinct, filiform, primary, dorsal ridges, and alter- nating with them are four obtuse, secondary ridges. Vittce, one beneath each secondary ridge, one beneath each of the broad marginal primary 208 Materia Medica. ridges, and two on each side of the suture of the commissure, the exter- nal ones being very minute. The above description is gathered from those given by Don, Fontannier, and others. History.—For a long time a knowledge of the plant which furnishes the Gum Ammoniac was a matter of doubt and uncertainty, but from specimens obtained in Persia, by Colonel Wright, and examined by Dr. David Don, it was ascertained to belong to a genus, Dorema, and not to the Ferula, as was formerly supposed, although somewhat allied to it. The Dorema Ammoniacum is an umbelliferous plant, growing spontane- ously in various Persian provinces, in dry plains and gravelly soils. In the month of May, or in the early part of summer, it abounds in a milky juice, which flows out upon the slightest puncture. M. Fontannier states that it exudes spontaneously, and that the harvest is about the middle of June ; but Captain Hart says that when the plant is mature, it is pierced in all directions by an insect of the beetle kind ; the juice exudes through the punctures thus made, hardens upon the surface, and when dry is collected by the natives. It is still supposed, however, to be sometimes fur- nished by other and dissimilar plants of Asiatic as well as African growth. Gum Ammoniac is not a pure gum, but a gum-resin ; it comes to us in tears, or in aggregate masses, and is frequently mixed with foreign matters. The tears are the preferable parts to use ; the purest are irreg- ular in shape, more or less globular, opake, yellowish externally, whitish internally, compact, homogeneous, brittle when cold, and breaking with a conchoidal shining fracture. The masses are darker, and of less uniform structure, and appear when broken, to be composed of numer- ous tears imbedded in a grayish or brownish substance. Ammoniac has a peculiar smell, which is stronger in the masses than in the tears ; the taste is bitter, slightly sweetish, and somewhat acrid. Its specific gravity is 1.207. It softens by heat, and becomes adhesive, but does not melt; and when burned, it swells up, with a white flame, and emits a smoke of a strong, resinous, slightly alliaceous odor. It forms an opake milky emulsion when triturated with water, but which becomes clear upon standing. It is partly soluble in alcohol, ether, vinegar, and alkaline solutions ; the alcoholic solution is clear, but becomes milky on the addition of water. Properties and Uses.—Stimulant and expectorant, and in large doses cathartic. Used in chronic catarrh, asthma, cough, and chronic pulmo- nary affections, where from debility of the vessels there is too large a secretion from the bronchial mucous membrane, or where expectoration is deficient. It has likewise been advised in chronic amenorrhea, espe- cially when attended by hysterical or chlorotic conditions of the system. It is unsuited to inflammatory affections. Dose, ten to thirty grains in pill or emulsion. Externally, used in the form of plaster, as a discutient or resolvent in scrofulous tumors, tumors of the joints, indolent tumors, etc. Ammonia. 209 Gum Ammoniac enters into a cement for mending glass, china, etc., and which is useful to druggists, physicians, chemists, and others ; it is called Armenian Cement, and Diamond Cement, and on account of its utility we give its mode of preparation. Take of isinglass two drachms, sprinkle it with water, and allow it to stand until softened, then add as much proof spirit as will rather more than cover it, and dissolve it with a moderate heat. Take of gum mastic one drachm, and dissolve it in two or three drachms of rectified spirit. Mix these -two solutions, and stir in one drachm of gum ammoniac, which has been previously reduced to fine powder, and rubbed down with a little water. If necessary, evapo- rate in a water-bath to about the consistence of thick molasses, and keep it in a bottle. When required for use place the bottle in warm water, and allow the cement to soften, then apply it with a stick, or a small hard brush to the china or glass previously warmed. Compress the pieces firmly together until cold, taking care to make the contact perfect, and using a very thin layer of cement. When properly applied the cement is almost, if not quite, as strong as the china itself, unless exposed to the combined action of heat and moisture. AMMONIA. Ammonia. History.—Ammonia was unknown to the ancients; it was discovered in a state of solution by Black in 1756, and in the pure gaseous condition by Priestley in 1774. All the ammoniacal compounds owe their dis- tinctive properties to the presence of this gas, which is composed of one equivalent of nitrogen 14, and three of hydrogen 3,=17. Its symbol is NH3 ; its specific gravity is 0.59. Ammonia may be obtained from any one of its salts by the process of single decomposition ; but on account of its cheapness it is most generally obtained from the muriate of ammonia or sal-ammoniac, acted on by lime. The chemical changes that occur are disengagement of the am- monia, and a union of the lime with the hydrochloric acid, forming chloride of calcium and water. Under ordinary atmospheric temper- atures and pressures ammoniacal gas is permanent; but at 50°, and under a pressure of six atmospheres, it is condensed into a colorless, very mobile liquid of the density of 760. It is transparent and colorless, like common air, but possesses a hot, acrid taste, and a highly pungent, suf- focating odor; it is irrespirable, spasmodically closing the glottis when an attempt is made to inhale it, and irritates and inflames animal tex- tures. It has a powerful alkaline reaction, turning reddened litmus paper purple, turmeric brown, and blue cabbage green. It combines readily with acid, forming crystallizable salts which are either sublimed or 14 210 Materia Medica. decomposed by heat,—those with volatile acids being sublimed without change, while those with fixed acids part with their ammonia. In contact with a gaseous acid, the two gases unite, and solidify, forming a white powder. It is absorbed by alcohol, but more especially by water. Water of 59° F, at the atmospheric pressure of thirty inches absorbs 670 times its volume of ammonia. The salts of ammonia are divided into hydracid salts, in which it is supposed the hydrogen of the acid is transferred to the elements of the ammonia during the act of uniting; and oxacid salts, in which the acids combine with oxide of ammonium ; this oxide is supposed to be formed by the union of the elements of one equivalent of water, (.which is always contained in the oxacid salts of ammonia, and which cannot be separated without destroying their nature,) with the elements of one equivalent of ammonia.

AMMONITE HYDROCHLORAS. (Ammoniae Murias.) Chlorohydrate, or Muriate of Ammonia. sal ammoniac. History.—Formerly, Sal-ammoniac was obtained from Egypt, where it was manufactured by subliming the soot resulting from the burning of camel's dung, which is used there as fuel. At present it is prepared in various ways, for instance, by the union of hydrochloric acid gas and ammoniacal gas ; or by the double decomposition of sulphate of ammo- nia and muriate of soda. The sulphate of ammonia is obtained from various sources ; sometimes by lixiviating the soot of coal, sometimes by decomposing with sulphuric acid the ammoniacal salts contained in the watery fluid which is formed in manufacturing coal gas, and sometimes by decomposing with sulphate of lime or sulphate of iron the impure car- bonate of ammonia produced by the destructive distillation of animal refuse, but more especially in the preparation of animal charcoal from bones. The hydrochlorate of ammonia which is consumed in the United States, is of foreign manufacture ; the crude variety being imported from Calcutta; the refined from England. It is usually sold in thick cakes, convex on one surface, concave on the other, white, translucid, tough, fibrous, permanent in the air, no odor, but possessing a pungent, saline, acrid taste. It is composed of one equivalent of hydrochloric acid 36.42, and one of ammonia 17=53.42 ; or, in ultimate constituents, Ammonite Hydrochlqras. 211 of one equivalent of chlorine, one of nitrogen, and four of hydrogen. According, however, to the new view taken of the constitution of ammo- niacal salts, it is the protochloride of ammonium, (NUi CL). Its spe- cific gravity is 1.45. Three parts of cold, and one of boiling water, dissolves it, and cold is produced during its solution. Alcohol partially dissolves it. It is difficult to pulverize, which, however, may be effected by stirring a boiling saturated solution of the salt; as it cools, it granu- lates, and after being dried, is readily pulverizable. In a damp atmos- phere it becomes moist. Heat sublimes without decomposing it. It is incompatible with the mineral acids, potassa and its carbonates, soda, lime, magnesia, acetate of lead, nitrate of silver, and most metallic salts whose base forms insoluble salts with muriatic acid. Properties and Uses.—Internally, it is refrigerant, laxative, diaphoretic and diuretic ; being purgative in large doses, but constipating in small ones. Its primary influence is exerted on the alimentary canal; its secondary, on the capillary, glandular, and lymphatic systems, as well as on the mucous, serous, and fibrous tissues, on all of which it acts as a stimulating alterative. In very large doses, it acts as a narcotic irri- tant, producing inflammation of the alimentary canal, and also coma and tetanic convulsions. It has been recommended internally in all tubercu- lous diseases, in chronic pulmonary affections, rheumatic face-ache, hemicrania, ischuria, chronic dysentery, amenorrhea the result of defi- cient uterine action, and in all chronic diseases of mucous or serous tis- sues. The dose is from five to thirty grains, every two or three hours, in powder, mixed with powdered gum, or sugar, or dissolved in syrup or mucilage. Externally, muriate of ammonia employed in solution, has been found valuable as a stimulant and resolvent, in contusions, chilblains, indolent tumors and ulcers ; and is of benefit in chronic ophthalmia, some forms of headache, itch, and many cutaneous affections. In erysipelas and erysipelatous inflammations, I have found the following mixture an excellent local application : Take of muriate of ammonia, one ounce, distilled water, half a pint; mix, and dissolve, then add tincture of camphor, four ounces, tincture of lobelia, four ounces. To be shaken each time previous to bathing with it. It allays the burning heat and itching, and in many instances assists in preventing the further develop- ment or extension of the disease. As a gargle, in the chronic form of cynanche tonsillaris, it is often serviceable, in solution ; about one ounce of the salt to nine fluidounces of water, and one of alcohol, is of conve- nient strength. As a wash for ulcers, or as an injection in leucorrhea, the solution must be still further diluted,—say from one to four drachms of the salt to a pint of water. Off.

Description.—This is a woody vine, with a rooting, climbing stem,— quinate and digitate leaves; leaflets, oblong, acuminate, petiolate, den- tate, smooth, and turn crimson in autumn ; flowers inconspicuous, green- ish, or white, in dichotomous clusters ; calyx entire ; petals five, distinct, spreading; ovary two-celled, cells two-ovuled ; style very short; berries dark-blue, acid, smaller than peas, and two-celled, cells one or two- seeded. History.—The American Ivy is a common and familiar shrubby vine, climbing extensively, and, by means of its radicating tendrils, supporting itself firmly upon trees, ascending to the hight of fifty feet; in the same manner it ascends and overspreads walls and buildings ; its large leaves constituting a luxuriant foliage of dark glossy green. It is found in wild woods and thickets throughout the United States, and blossoms in July, ripening its small blackish berries in October. In various sections it has different names, as Woodbine, Virginian Creeper, Five Leaves, False Grape, Wild Wood Vine, etc. The bark and twigs are the parts used. It is considered a valuable remedy. Properties and Uses.—Alterative, tonic, astringent, and expectorant. Used principally in form of syrup in scrofula, syphilitic affections, and wherever an alterative is required. It has also been recommended in bronchitis and other pulmonary complaints. Dose of the syrup or decoction, two to four ounces, three times a day. Off. Prep.—Decoctum Ampelopsis; Infusum Ampelopsis.

Sweet Almonds. Description.—The Amygdalus Communis or Almond tree is a tree from fifteen to twenty feet high, with a pale-brown rugged bark, and Amygdala Communis. 213 dividing into numerous spreading branches. The leaves are upon short footstalks, are about three inches long, and three quarters of an inch broad, lanceolate, acuminate, thin, veined, minutely serrated, with the lower serratures and petioles glandular, and of a bright light-green color. The flowers are large, pink or white, sessile, in pairs, and appear- ing before the leaves. Calyx reddish, with blunt segments. Petals variable in size, always much larger than the calyx, ovate, concave, irregularly notched. Stamens spreading, about half the length of the petals. Ovary woolly ; style simple. Fruit a leathery, hoary drupe, with the sarcocarp spontaneously cracking and dropping off the puta- men. Stone oblong, or ovate, acute, hard in various degrees, always rugged, and pitted with irregular holes. Seed oblong, compressed, ovate, with a brown testa, at the apex of which there is a broad round brown chalaza. Cotyledons very large, plano-convex. Both the sweet and bitter almonds are taken from this tree, of which there are several varieties,—the sweet almond is obtained from the A. Dulcis, and the bitter almond from the A. Amara. History.—The Almond tree is a native of most of the warm parts of Asia, and Barbary, and is cultivated in many parts of southern Europe. The best of the sweet kind come from Malaga. The kernel of the sweet almond is inodorous, farinaceous, and of an agreeable taste ; that of the bitter almond is also inodorous when entire ; but when triturated with water, has the odor of prussic acid, and the taste resembles that of the peach kernel. Both varieties of kernel contain oil; the sweet, a fixed oil; the bitter a fixed oil, and an essential oil impregnated with hydrocyanic acid. The fixed oil maybe obtained by expression; it is colorless or slightly yellowish, sweet and bland to the taste. The essen- tial oil may be obtained from the bitter almonds by distillation with water, after having deprived them of their fixed oil. This oil, called Oil of Bitter Almonds, is of a yellowish color, heavier than water, with an acrid, bitter, burning, taste, and the odor of hydrocyanic acid ; it is soluble in alcohol or ether, slightly soluble in water, and deposits on standing, crystals of benzoic acid. This oil does not pre-exist in the almond, but is formed by the action of water on some of its constituents, termed emulsin, and amygdalin; the latter is a crystalline substance peculiar only to the bitter almond. Oil of bitter almonds is a most active poison, acting as rapidly as hydrocyanic acid, and giving rise to the same symptoms. It is seldom used as a medicine, but is largely employed by perfumers, confectioners, and cooks, who prepare from it an " essence of almonds," which is a solution of two drachms of the oil in six drachms of alcohol. A potassa soft soap, made with lard and perfumed with essential oil of almonds is sold as a shaving soap, under the name of Saponaceous Cream of Almonds. It is made by melting fine clarified lard, seven 214 Materia Medica. pounds, in a porcelain vessel, by means of a salt-water bath, or a steam heat under fifteen pounds pressure; then run into it, very slowly, potassa ley, containing about twenty-six per cent, of caustic potassa, three pounds and twelve ounces, agitating continually from right to left during the whole time. When about half the ley is run in, the mixture begins to curdle; it will, however, finally become so firm and compact that it can- not be stirred, if the operation is successful. The soap is now finished, but is not pearly ; it will, however, assume that appearance by long trituration in a mortar, gradually adding rectified spirit two ounces, in which has been dissolved, essential oil of almonds two drachms. Properties and Uses.—Sweet almonds are demulcent, and are chiefly used in emulsion, and as a vehicle for other medicines. The oil or emul- sion has been employed in cough, diseases attended with intestinal irri- tation, and for mitigating the acrimony of the urine in calculous affec- tions, cystitis, gonorrhea, etc. Externally, the oil is sometimes used in lotions and cosmetics. Dose of the oil, one to two drachms. Bitter almonds are sedative, and in large doses poisonous. The oil of bitter almonds, or bitter almond water, is commonly employed, and may be used as a substitute for hydrocyanic acid. Dose of the oil, one quarter of a drop to one drop, gradually and cautiously increased. Seldom used. Off. Prep.—Aqua Amygdalae Amara; Mistura Copaibee Composita; Oleum Amygdalae. AMYGDALUS PERSICA. Peach. Not. Ord. — Rosaceae. Drupaceae, De Candolle. Sex. Syst. — Icosandria Monogynia. LEAVES AND KERNELS. Description.—Amygdalus Persica, or Peach tree, is farailar to almost every one. It is supposed to be originally a native of Persia. The leaves are lanceolate, serrate, with all the serratures acute ; flowers soli- tary, subsessile, appearing before the leaves, rose-color, with the odor of hydrocyanic acid; drupe fleshy, tomentose, yellowish, tinged with pur- ple ; calyx five-cleft, tubular, deciduous; petals five; nucleus somewhat compressed, ovate, acute, rugosely furrowed, and perforated on the surface. History. — The peach tree is cultivated in all parts of the United States, where the character of its fruit attains to greater perfection than in any other country. Its hight is from eight to fifteen feet, its fruit is Amylum. 215 large, being from one to three inches in diameter, juicy, abounding in saccharine matter, and of a delicious flavor. The leaves are from three to five inches long, about one-third as wide, smooth, green, petioles short, with one or two glands. There are about two hundred varieties of this fruit, of which, probably, one-third are clingstones, the flesh ad- hering to the stone, and the remainder freestones or clearstones, the flesh free, or separating from the stone. The kernels of the fruit bear a strong resemblance to bitter almonds, in appearance, properties, and probably chemical nature; and, together with the leaves, flowers, and bark, have also their peculiar odor and taste, and would very likely yield hydrocyanic acid. The leaves afford a volatile oil by distillation. Properties and Uses.—Peach leaves are sedative, laxative, and re- puted anthelmintic. In all inflammations of the stomach and abdomen, they exert a decidedly beneficial influence when used in cold infusion, a tablespoonful every hour or two. In hooping-cough, irritable bladder, sick stomach, ischuria, hematuria, and dysentery, they have been found useful. The kernels are similarly employed in the form of tincture, in- fusion, or syrup ; four ounces of the kernels to a quart of brandy is as- serted to form a powerful tonic in intermittent fever, and to be remark- ably efficacious in curing leucorrhea; dose, a teaspoonful three or four times a day. Both leaves and kernels are said to contain hydrocyanic acid. Off. Prep.—Infusum Persicee. AMYLUM. Starch. THE FECULA OF THE SEEDS OF TRITICUM VULGARE. History.—Starch is a principle contained in various organs of many plants, as wheat, rye, barley, oats, rice, peas, beans, chestnuts, acorns, potato, etc.; and is extracted from many of them for dietetic and medi- cinal purposes, under the several names of Starch, Arrow-root, Tapioca, Tous-les-mois, and Sago. It abounds especially in the different kinds of grain, among which, wheat, yields one of its purest varieties, and from which an average of about from fifty to sixty per cent, is to be had. In preparing starch from wheat-flour, the flour, which consists of starch, gluten, mucilage, albumen, several salts, and some bran, is kneaded in a cloth with successive portions of cold water. The gluten and bran re- main in the cloth; the mucilage, albumen, and salts dissolve in the water ; and the starch passing away with the water in a state of suspension, gradually falls to the bottom. By allowing the albumino-mucilaginous water, from which it has subsided, to undergo fermentation, the starch is 216 Materia Medica. thereby purified from the gluten; for the acetic acid formed during this process, dissolves the gluten. Starch is of the purest white, pulverulent, opake, nearly inodorous, and tasteless, and is usually had in small, columnar, irregular prisms. Its specific gravity is 1.53. In dry air it is permanent; in moist air it absorbs about twenty-four per cent, of water, without losing its dry ap- pearance, and which may be driven off by a gentle heat. In its ordin- ary state it contains about twelve per cent, of moisture. It is insoluble in alcohol, ether, oils, and cold water. Alcohol removes from it a trace of essential oil, on which its odor and taste depends. Diluted sulphuric acid resolves it into sugar; nitric acid into malic and oxalic acids. When starch has been triturated or agitated with water, a dark purple com- pound is formed; a solution of starch made with hot water, and sub- sequently cooled, yields on the addition of iodine, an immediate deep- blue precipitate of iodide of starch ; thus iodine is the most delicate test of its presence in any mixture. The color varies with the proportions employed; when the two substances are about equal, the compound is of a beautiful indigo-blue; if the iodine is in excess, it is blackish-blue; if the starch, violet-blue. A solution of iodide of starch, when heated to 200°, becomes colorless, but on cooling recovers its blue color; boil- ing permanently destroys the color. Alkalies form soluble compounds with starch, from which it may be precipitated by acids. Lime-water, and baryta-water, precipitate it from its solution, forming insoluble com- pounds. When starch is roasted, it is converted into a substance soluble in cold water, called British Gum, which may be applied in the arts to the same purposes as gum. Starch consists of organized granules, of various form and size, being small, globular, oval, or angular. These granules have each a thin ex- terior pellicle or tegument, insoluble in water, and an interior, soluble substance. Amylin is the name applied to the external tegument; amidin, to the interior mucilaginous portion. Dextrin is amidin ren- dered impure with variable proportions of starch-sugar, and starch-gum —and may be prepared by boiling the starch for a long time in dilute sulphuric, muriatic, or oxalic acid; and if the boiling be still further continued, a saccharine substance is produced, similar to the sugar of grapes. Diastase is a principle developed in the seeds of barley, oats, wheat, etc., by germination. Starch consists of carbon, 44, hydrogen, 6.22, and oxygen, 49.78 ; its formula is C12 Hio Oio. Properties and Uses.—Starch is demulcent and nutritive. It is used in mucilage, or in emulsion, for suspending drugs, when to be given in- ternally or by injection. The powder is dusted upon the skin to absorb irritating secretions; to prevent excoriation; to soothe the pain of erysi- pelas, and to prevent intertrigo in infants. Starch may be used as an antidote to iodine. Anacyclus Pyrethrum — Anagallis Arvensis. 217 ANACYCLUS PYRETHRUM. Pellitory of Spain. Nat. Ord. — Compositaa, (Decandolle) Asteraceaa, (Lindley). Sex. Syst.— Syngenesia Superflua. ROOT. Description.—This is the Anthemis Pyrethrum of Willdenow, and of the U. S. Dispensatory, the name of which has been changed by De Candolle, and the plant placed into a new genus on account of a differ- ence in the structure of its seeds. Its stems are numerous, procumbent, somewhat branched, pubescent. Radical leaves spreading, petiolated, smoothish, pinnately divided; the segments much cleft into linear, subu- late lobes ; cauline leaves sessile. Branches one-flowered. Receptacle convex, with oblong-obovate, obtuse paleae. Florets of the disk are yellow ; the rays are white on their upper surface, and reddish or purple beneath and at their edges. History.—Pellitory of Spain, or Spanish Chamomile is a native of the Levant, Arabia, Syria, and the South of Europe. The root is the offi- cinal part, and as found in the shops it is about the size of the little finger, cylindrical, straight, or but slightly curved, wrinkled longitudi- nally, of an ash-brown color externally, whitish within, hard and brittle, and sometimes furnished with a few radicles. It is inodorous, though when recent it possesses a very disagreeable smell; when chewed it produces a peculiar sense of heat, pungency and tingling in the mouth, which lasts for some time, and which is attended with a copious flow of saliva. Analysis gives a brown, very acrid substance, of a resinous ap- pearance, which is insoluble in caustic potassa; a dark brown, very acrid, fixed oil, soluble in potassa, a yellow acrid oil, traces of tannin, gum, inulin, and various salts. Alcohol or ether dissolves its active principle. Properties and Uses.—Irritant and sialagogue. Used in neuralgic affections of the head and face, toothache, paralysis of the tongue, and of the muscles of deglutition. The tincture makes a good rubefacient and odontalgic remedy. ANAGALLIS ARVENSIS. Red Chickweed. Nat. Ord.—Primulaceas. Sex. Syst.—Pentandria Monogynia. THE LEAVES. Description.—Anagallis Arvensis is a beautiful annual trailing plant, in fields, roadsides, etc., introduced into this country from Europe. Its 218 Materia Medica. stem grows from six to twenty inches long, with elongated branches, or simple, often dotted with purple, square, and more or less procumbent. The leaves are sessile, ovate, many-ribbed, opposite or ternate, dotted with purple at the back ; peduncles longer than the leaves; sepals linear- lanceolate, about equaling the petals; petals obovate, obtuse, longer than the stamens, crenate-glandular. Flowers opposite, small but beau- tiful, with scarlet petals, opening at 8 o'clock, a. m., and closing at 2, p. m.; in damp weather not open at all. Stamens purple, hairy, dilated, and smooth at the base. Anthers yellow, heart-shaped. Style purple, permanent. Stigma capitate. Capsule pale and transparent, the size of a pea, separating all round, the valves marked with some indications of longitudinal separations which seldom take effect. Seeds roughish, abrupt externally, each with a central dot. History.—This plant has several names, as Red Pimpernel, Poor Man's Weather Glass, Scarlet Pimpernel, etc. It blossoms in June and July. The leaves are the parts used, they are inodorous, but have a bitter, some- what acrid taste. Water extracts their virtues. The plant appears to possess energetic properties, for Orfila destroyed a dog by making him swallow three drachms of the extract; it inflamed the mucous mem- brane of the stomach. Grenier obtained a similar result. Properties and Uses.—The precise properties of this plant are not fully known. It was formerly esteemed as a counter poison, and has been used as a preventive of hydrophobia. Its internal use has been recommended in visceral obstructions, dropsy, mania, epilepsy, delirium, and other nervous diseases; also in febrile delirium. But too little is known of its action to warrant its indiscriminate employment in these diseases. It may, however, be used in form of poultice, as a local application to old and ill-conditioned ulcers. ANAMIRTA COCCULUS. Cocculus Indicus. Nat. Ord.—Menispermacese. Sex. Syst.—Dicecia Dodecandria.

Description.—Anamirta Cocculus, formerly called according to Lin- naeus, Menispermum Cocculus, is a strong, climbing shrub, with a corky, ash-colored bark, with deep cracks or fissures; the leaves are thick, smooth, shining, coriaceous, roundish, acute, very slightly cordate, if at all, sometimes truncate at the base, with five digitate ribs, about six inches long, and as many broad; stalks a little shorter than the leaves, tumid at both ends, especially the lower. Flowers dicecious; female Andira Inermis. 219 flowers in lateral compound racemes. Calyx of six sepals in a double series, with two closely-pressed bractioles. Corolla none. Stamens united into a central column dilated at the apex. Anthers numerous, covering the whole globose apex of the column. Drupes, one to three, globose, one-celled, one-seeded. Seed globose, deeply excavated at the hilum. Albumen fleshy. Cotyledons very thin, linear-oblong, distant, diverging, very membranous. History.—This plant is a native of the Malabar coast, and of eastern insular and continental India. The parts used are the berries or fruit, which, as found in the shops, are round, subreniform, about the size of a pea, inodorous, of a grayish-black color, and composed of an external, thin, hard, brittle shell, covering another, which is white, and still denser, and contains a white nucleus divided by a central placenta. They are inodorous, but have an intensely and permanently bitter taste. They contain picrotoxin, or picrotoxic acid, which is a very bitter, poison- ous principle, menispermin, an alkaline principle, paramenispermin, hy- popicrotoxic acid, fixed oil, etc. Properties and Uses.—Poison. Given to animals it acts on the cere- brospinal system, causing nervous tremors, convulsions, and tetanus; it also acts on the stomach as a local irritant. It is never used internally, but has been applied externally in form of powder or ointment, in some obstinate cutaneous affections, tinea capitis, and for the destruction of vermin in the hair. It is sometimes used to stupefy fish in order that they may be caught, and it is asserted that the fish thus taken are not poisonous. It is likewise added to malt liquors to render them bitter and intoxicating, but which is highly improper and dangerous. ANDIRA INERMIS. Cabbage-tree Bark. Nat. Ord.—Fabaceaa. Sex. Syst.—Diadelphia Decandria. THE BARK. Description.—Andira Inermis, ( Geoffroya Inermis), is a tree of mode rate hight, branched toward the top, and covered with a smooth gray bark ; the branches are suberect at their extremities, terete, glabrous, ash-colored. The leaves are about a foot in length, alternate, unequally pinnate, consisting of five to eight pairs of oblong-lanceolate, acuminate, veined, smooth leaflets, of a dark-green color, on short roundish ferru- ginous downy stalks, with a terminal one on a longer footstalk. The flowers are rose-colored, large, branched, and arranged in erect, axil- lary, terminal downy panicles, with very short pedicels. The calyx is turbinate-campanulate, covered with ferruginous down, of a dark-purple 220 Materia Medica. color, and divided into five obtuse segments. The corolla is of a pale- rose color, papilionaceous, having a concave vexillum, emarginate at the top, and longer than the carina. The stamens are purple, diadelphous, with roundish anthers. The ovary is oval, with a tapering, curved style, and hooked stigma. The fruit resembles a small plum, is pulpy, and contains a hard nut, or legume. History.—This tree is a native of Jamaica and other of the West India Islands. The bark is the officinal part; it is in long, thick, fibrous pieces, externally of a brownish-ash color, and generally covered with lichens, and internally yellowish. It has a resinous fracture, a disagree- able smell, and a sweetish, mucilaginous, bitterish taste. Properties and Uses.—Cabbage-tree Bark is emetic, purgative, and anthelmintic. It is thought by some to be a dangerous acro-narcotic in large doses, causing troublesome sickness, fever, and delirium; on which account it is not much used in practice, although it has proved effectual in removing the lumbricoid worms. Dose of the powdered bark, from a scruple to a drachm ; of the extract three grains; of the syrup or decoction, a teaspoonful two or three times a day. If any narcotic or other unpleasant effects arise, a dose of castor-oil must be administered, and the patient must take freely of lime-juice. ANDROMEDA ARBOREA. Sorrel Tree. Nat. Ord.—Ericaceas. Sex.

The flowers are pedicellate, secund, spreading, at length reflexed; panicles terminal, consisting of numerous spicate racemes. Calyx without bractlets. Corolla ovate-oblong, narrowed at the summit, five-toothed, pubescent externally. Filaments thickened; anthers awnless, the cells long and pointed; capsule pyramidal, pentan- gular ; seeds ascending from the base, linear, with a loose coat taper- pointed at both ends ; bracts and bractlets minute, deciduous. History.—This is a beautiful tree, growing in the valleys of the Alle- ghany mountains, from Pennsylvania to Florida, and bearing white flowers in July. The leaves are the parts used ; they have a very plea- sant acid taste, and yield their properties to water. Anemone Nemorosa. 221 Properties and Uses.—Sorrel Tree leaves are tonic, refrigerant and diuretic. A decoction of the leaves is a grateful refrigerant drink in fevers, and will also produce diuresis. Some species of the Andromeda are poisonous, as the A. Ovalifolia, A. Polifolia, A. Mariana, A. Nitida, and A. Angustifolia; the powder upon the leaves and buds of the A. Speciosa, and A. Pulverulenta, is a powerful errhine. ANEMONE NEMOROSA. Wood Anemone. Nat. Ord.—Ranunculaceae. Sex. Syst.—Polyandria Polygyria. THE PLANT. Description.—Anemone Nemorosa, sometimes called Windflower, is a delicate and pretty plant, with a creeping root, and a simple, erect stem, with a single flower on a naked peduncle, and from six to nine inches high. The leaves are radical and ternate, and the leaflets undivided, or with the middle one three-cleft, and lateral ones two-parted, incisely dentate; involucre at the base of the flower-stalks, long petioled, divided into three, toothed, and cut: sepals four to six, oval, white, sometimes tinged with purple outside ; carpels fifteen or twenty, ovate, with a short style, hooked. Stamens numerous, much shorter than the sepals; ovaries numerous, free, collected into a roundish or oval head. History. — This plant is common to Europe and the United States, bearing purplish-white flowers in April and May. There are several varieties of it, which possess similar properties, as the A. Patens, of this country, the A. Pratensis and A. Pulsatilla, or Meadow Anemone of Europe. The last is probably the most active among them. The her- baceous part of the plant is employed in medicine. A volatile, crystal- lizable solid, called Anemonine is obtained from the various species of anemone, by distilling the plants with water, and setting the product aside; it crystallizes in brilliant white needles. Its formula is Cj H2 O2. Alkalies convert it into anemonic acid. A solution of it has been used externally in scaldhead, ulcers, caries, indurated glands, venereal nodes, serpiginous affections, paralysis, amaurosis, cataract, and opake cornea. Its internal use is questionable. Properties and Uses.—These plants are acrid and poisonous. They have been recommended in amaurosis and other diseases of the eye, secondary syphilis, cutaneous diseases, and hooping-cough, in doses of one or two grains daily. When applied to the head, it is said to be a speedy cure for tinea capitis. In the recent state, the leaves bruised and applied to the skin are rubefacient. In large doses, this article produces 222 Materia Medica. nausea, vomiting, looseness of the bowels, and bloody urine.

Description.—Angelica Atropurpurea, sometimes called Masterwort, High Angelica, etc., has a perennial, purplish root, and a smooth, herba- ceous stem, hollow, glaucous, from one to two inches in diameter, and risino- from three to six feet high; its dark purple color has given rise to its specific name. The leaves are ternate, and supported by very large inflated petioles. The leaflets are pinnate, five to seven, sharply cut-ser- rate, acute, pale beneath, the terminal one sometimes three-lobed, the lateral ones of the upper division decurrent. Umbels three, large, ter- minal, many-rayed, spreading, spherical, six to eight inches in diameter, without the involucre. Umbellets dense, subhemispheric, on angular stalks, and with involucels of subulate bracts longer than the rays. Calyx five-toothed ; petals equal, entire, with the point inflected. Invo- lucels short, about eight-leaved. Fruit smooth, compressed, somewhat solid and corticate, elliptic. History.—This plant grows from five to eight feet high, throughout the United States, in meadows and marshy woods, and flowers in June and July; the flowers are greenish-white. The whole plant has a strong odor, and a warm aromatie taste. The juice of the recent root is acrid, and is said to be poisonous; drying dissipates much of this acri- mony. Properties and Uses.—Aromatic, stimulant, carminative, diaphoretic, ex- pectorant, diuretic, and emmenagogue. Used in flatulent colic and cardial- gia. It is said to promote the menstrual discharge. In diseases of the uri- nary organs, calculi and passive dropsy, it is used as a diuretic, in decoction with uva ursi and eupatoreumpurpureum. Dose of the powder, thirty to sixty grains; of the decoction, two to four ounces, three or four times a day. The Angelica Archangelica, A. Triquinati and A. Lucida, may be substituted for the above. Antennaria Margaritaceum—Anthemis Nobilis. 223 ANTENNARIA MARGARITACEUM. Pearl Flowered Life Everlasting. Nat. Ord.—Composites or Asteracese. Sex. Syst.—Syngenesia Superflua. THE LEAVES. Description.—Antennaria Margaritaceum is a perennial plant, with a simple, erect stem, corymbosely branched above ; the leaves are linear- lanceolate, acute, three-veined, sessile, and beneath the stem woolly; corymbs many-flowered, fastigiate ; scales of the hemispheric involucre elliptic, obtuse, opake, pearl-white, the outer ones only tomentose at the base. Heads dicecious ; the pistillate flowers very slender ; pappus simple, bristly, capillary in the fertile flowers, and in the sterile club- shaped or barbellate at the summit. Corolla yellowish. History.—The name Antennaria is from the resemblance of the sterile pappus to the antennce of many insects. The plant is slightly fragrant, and grows in dry hills and woods in various parts of the United States ; it is from one to two feet in hight, and bears yellow and white flowers in July. The leaves are the parts used. Properties and Uses.—Anodyne, astringent and pectoral. A decoc- tion has proved beneficial in diarrhea and dysentery, and in pulmonary affections. Used externally as a cataplasm in painful tumors, contusions and sprains, and is certainly very efficacious in relieving pain and dis- posing to sleep, often succeeding where the hop poultice has proved inef- fectual. The A. Plantagineum, and A. Dioicum, or white plantain, are supposed to be beneficial in snake-bites. ANTHEMIS NOBILIS. Chamomile. Roman Chamomile. Nat. Ord.—Compositae Senecionideas, or Asteraceas. Sex. Syst.—Syngene- sia Superflua, FLOWERS. Description. — This is a herbaceous plant with a strong, perennial root, having long fibers. The stems in a wild state are prostrate, in gardens more upright, from six to twelve inches long, branched, leafy, round, slender, hollow, furrowed, downy. The leaves are pale-green, bipinnate, sessile, with small, thread-like leaflets which are rather flat or channeled above, convex beneath, somewhat pubescent, acute, and gen- erally divided into three segments. The flower-heads are terminal, soli- 224 Materia Medica. tary, rather larger than a daisy, with a convex yellow disk, and numer- ous white, spreading, or reflexed rays. The calyx is common to all the florets, of a hemispherical form, and composed of several small imbri- cated hairy scales, with thin, membranous edges. The receptacle is coni- cal or convex, prominent, and furnished with rigid bristle-like paleae, one to each floret; the scales of the receptacle do not appear till the florets of the disk are turned to one side, and the innermost are gradually nar- rowest. The florets of the ray are usually about eighteen, narrow, ligu- late, white, spreading, three-toothed; the disk florets are numerous, yel- low, perfect, tubular, divided into five lobes. The stamens are five, very short. The ovary is obovate, and supports a slender style, with a bifid, reflexed stigma. The seeds are ovate, compressed, and slightly crowned. History.—Chamomile is a native of Europe, and is extensively culti- vated for medicinal purposes; by cultivation the flowers become double, but the properties are not so great in these as in the single flowers, because the disk contains the virtues in the greatest degree. The flowers which are the whitest are the best; the seeds yield a fixed oil by expression. As found in the shops, chamomile flowers are large, almost spherical, of a dull-white color, a fragrant odor, and a warmish, bitter, aromatic taste. By distillation they yield a volatile oil, at first of a pale, blue color, but which changes to yellow or brownish; its stimu- lant properties depend on this oil, and a resin ; the tonic, on its bitter extractive; it also contains a small quantity of tannin. Schendler has obtained from the flowers a volatile acid in minute proportion, much resembling valerianic acid. Water or alcohol extracts their virtues; boiling water extracts nearly one-fourth of their weight. Properties and Uses.—In small doses tonic, and in large, emetic. Used in cold infusion in dyspepsia, and in all cases of weak or irritable stomach; also in intermittent and typhus. A strong infusion, warm, and taken freely, acts as an emetic. The oil is carminative and anti- spasmodic. Used in flatulency, colic, cramp in the stomach, hysteria, nervous diseases, and in painful dysmenorrhea. Dose of the oil, five to fifteen drops, on sugar; of extract, prepared in vacuo, which is the best form for internal administration, one to three grains. The flowers of the Matricaria Chamomilla, or German chamomile, possess similar properties to the anthemis, but are rarely used in this country, except by German practitioners. Off.

Ord.—Apiaceee or Umbelliferae. Sex. Syst.—Pentandria Digynia. ROOT. Description.—Apium Petroselinum, Willdenow, or Petroselinum Sati- vum, Hoffman, has a biennial, fleshy, fusiform root, with an annual, round, furrowed, joint, erect, branching stem, striate with green and yellow lines, and rising from two to four feet in hight. The radical leaves are compound, pinnated in ternaries, on long channeled stalks; the leaflets are rhomboidal-ovate, wedge-shaped at the base, deeply incised, with the segments mucronate, and sometimes rounded. Upper leaves gradually become more entire and narrower, till the uppermost are simply ternate with linear segments. Umbels terminal, axillary, pedunculated, and with five to eight rays. General involucre none, or one to two subulate minute bracts; partial involucre with six or eight setaceous bracts, much shorter than the pedicels, erect, forming a per- fect whorl. Flowers white or greenish; petals rounded, incurved, scarcely emarginate; calyx with the limb obsolete; disk short, conical, somewhat crenulate; styles diverging. Fruit ovate, about a line long, compressed, pale greenish-brown, flat on one side, convex on the other, and marked with five longitudinal ridges. Stamens longer than the corolla. History.—This plant is a native of Europe, but is cultivated in gar- dens throughout the civilized world. The whole plant has an aromatic odor, and the leaves are used for culinary purposes. The root, which is officinal, is fusiform and fleshy, with a pleasant smell, and sweetish taste; it should be used in the recent state. Its properties depend upon an essential oil, and are taken up by water, wine, alcohol, or ether. Properties and Uses.—Diuretic. Very useful in dropsy, especially that following scarlatina, and other exanthematous diseases. Also, used in retention of urine, strangury, and gonorrhea. The seeds have a strong, terebinthinate odor, and a warm aromatic taste, and have been used as carminatives, and for the same purposes as the root—they are said to be a deadly poison to the parrot. The seeds, as well as the leaves, sprinkled on the hair, in powder, or in the form of an ointment, will effectually destroy vermin; the leaves, applied as a fomentation, will, it is asserted, cure the bites or stings of insects. The leaves, bruised, are a good application to contusions, swelled breasts, and enlarged glands—reputed to "dry up the milk" of wet-nurses. The oil is effica- cious as a diuretic, in doses of three or four drops a day; dose of the infusion, two to four ounces, three or four times a day. Off.

Description.—Apocynum Androsaemifolium is an indigenous, peren- nial, herbaceous plant, with a large and bitter root, and an erect, smooth stem which rises from three to six feet high; it is simple below, repeat- edly branching above, usually red on the side exposed to the sun, lactescent, and covered with a tough, fibrous bark. The leaves are opposite, petiolate, ovate, acute, entire, smooth on both sides, paler and very slightly pilose beneath, and two or three inches long. Flowers in .*■• loose, nodding, terminal or axillary cymes, white, tinged with red, monopetalous, campanulate, with five acute spreading segments. The peduncles are furnished with minute, acute bracts. Calyx small, five- cleft, much shorter than the tube of the corolla. Stamens five, with very short filaments, and long, sagittate, connivent anthers, cohering with the stigma about their middle, and often holding fast such insects as may thrust their proboscis between them. The nectary consists of five oblong glandular bodies, alternating with the stamens. Ovaries two, ovate, concealed by the anthers and supporting two thick, roundish, sessile stigmas. The fruit is in the form of a pair of slender, linear- lanceolate, drooping follicles, containing numerous oblong, imbricated seeds attached to a slender central torus, and each crowned with a long, downy pappus. Every part of the plant is lactescent. History.—This plant, likewise called Dogsbane, Milk-weed, etc., is found in nearly all parts of the United States, from Canada to Carolina, growing in dry, sandy soil, on hill-sides, or in woods, flowering in June and July; when any part of it is wounded, a milky juice exudes. The root is the officinal portion, it is large, lactescent, and of a disagreeably bitter taste; the bark, which forms nearly two-thirds of it, is the active part. Analysis has discovered it to contain a bitter extractive, a red coloring matter soluble in water and not in alcohol, caoutchouc and volatile oil. It yields its properties to alcohol, but especially to water. Age impairs its virtues. Properties and Uses. — Emetic, diaphoretic, tonic, and laxative; it has been found very valuable in the treatment of chronic hepatic affec- tions, and in conjunction with Menispermum in dyspepsia and amenor- rhea. In doses of forty to sixty grains it promptly induces emesis, with scarcely any previous nausea, and hence is useful where it is desired to evacuate the stomach, without producing that muscular relaxation inci- dent to a long-continued nausea; however, it is said to occasion a Apocynum Cannabinum. 227 subsequent weakness or languor, from which the patient is some time in recovering. As a laxative, it is useful in cases of constipation, and in hepatic derangements. As a tonic, ten or twenty grains may be given to stimulate the digestive apparatus, and thus effect a corresponding im- pression on the general system. As a diaphoretic it must be combined with opium, in the proportion of one grain of the latter to forty of the former, and divided into three or four doses; however, as a diaphoretic, it is inferior. Also reputed useful as an alterative in rheumatism, scro- fula, and syphilis. Prof. Gregory speaks of Apocynine as the active agent of the A. Androsaemifolium, but has given no method of preparing it. It is said to be very bitter, and of a dark orange color. Used as an alterative in syphilitic and scrofulous affections, in doses of half a grain to a grain; as a purgative, one grain to two grains. It has been bene- ficially employed in liver and stomach affections, intermittents, and the low stage of typhoid fevers. I have used a preparation called Apocynin, prepared from this plant by Mr. J. B. Robinson of Cincinnati, Ohio, in jaundice, combined with leptandrin and myricin, with excellent effect, as well as in hepatic torpor, and constipation. It is a powder of a dark-brown color, posses- sing an odor similar to the root, and a bitter, nauseous, unpleasant taste. Mr. Robinson prepares it by neutralizing the saturated tincture of the root by ammonia, then filtering and precipitating the apocynin by sul- phuric acid, which must be added gradually; when obtained it is to be washed in one or two waters, and then dried. One pound of the root yields about half an ounce of the dried apocynin, and much care must be taken in the operation, lest the whole be spoiled. Off.

Description. — In general appearance and character the Apocynum Cannabinum bears a close resemblance to the Apoc. Androsaemifolium. The root is perennial and creeping; the stems are erect, herbaceous, branching, of a brown color, and two or three feet in hight. The leaves are opposite, oblong-ovate, acute at both ends, and somewhat downy beneath. The cymes are many-flowered, terminal and lateral, panicu- late, smooth. The corolla is small, of a greenish or yellowish-white externally, with a tinge of pink or purple within, with a campanulate 228 Materia Medica. tube not longer than the calyx. The calyx is about as long as the corolla, with subulate segments, lanceolate. Follicles long and slender. Fruit similar to A. Androsaemifolium. History.—This plant is indigenous and grows in similar situations with the Apoc. Androsaem., flowering about the same time. It likewise abounds in a milky juice, and has a tough, fibrous bark, which, by mace- ration, affords a substitute for hemp, but of a whiter color, and superior in strength and durability. A decoction of the plant affords a permanent brown or black dye, according to the mordant used. The root is the officinal part; when fresh it is of a dark-chestnut color, with a nauseous, somewhat acrid, and permanently bitter taste, and a strong, unpleasant odor. When dried it is brittle and readily pulverized, affording a powder somewhat resembling Ipecacuanha. The ligneous portion is yellowish-white, with some odor, and a decided bitter taste; the cortical part is brown externally, and white within, of a very bitter, nauseous taste. Analysis has ascertained it to contain tannin, gallic acid, gum, resin, wax, fecula, a coloring matter, caoutchouc, lignin, and a peculiar bitter principle to which the name of Apocynin has been proposed. The root yields its properties to alcohol, and more readily to water; its vir- tues are impaired with age. Every part of this plant, in the recent state, exudes a milky juice when wounded. Properties and Uses.—Emeto-cathartic, diuretic, and diaphoretic. In a full dose it occasions much nausea, diminishes the frequency of the pulse, and has a tendency to produce drowsiness independent of the exhaustion consequent upon vomiting; copious vomiting soon ensues, and subsequently large and feculent watery stools. A general per- spiration almost always follows. Its diuretic effects vary in different individuals, being very manifest in some and less so in others. Snuffed into the nostrils, the powder will excite sneezing. As a hydragogue cathartic, and also as a diuretic in those instances where this effect is displayed, it has been found most useful in dropsy. In diaphoretic doses it has proved beneficial in intermittent and remit- tent fevers, and pneumonic affections. As an emetic, from fifteen to thirty grains of the powder, is the dose ; as a hydragogue or diuretic, the decoction is the best form in which to employ it,—one ounce of the root may be boiled in a pint of water, of which a wineglassful may be given two or three times a day, or oftener if required. Smaller quan- tities of the decoction, given warm, will cause diaphoresis; as a purg- ative, the aqueous extract may be given in doses of from three to six grains. The apocynin obtained from this plant will probably be found identical in virtue and chemical constitution with that from the A, Androsaemifolium. Further investigations with it are required, before anything positive and satisfactory can be made known. Aqua. 229 AQUA. Water. History.—From the almost universal solvent powers of water, it is the most extensive pharmaceutical agent that we possess, beside being, when properly employed, a most valuable remedy for a large number of diseases. The purest water that can be obtained is distilled water, which when properly prepared in clean, glass vessels, is colorless, transparent, tasteless and inodorous, with the assumed specific gravity of unity, and with which as a standard, the specific gravities of all solids and liquids are compared. It is the only admissible water for pharmaceutic and chemical tests, as the presence of organic or saline substances in it, may decompose the articles to be dissolved, or impair its solvent power. At a temperature of 32° or lower it becomes ice; at 212° or above, it forms steam, in which its bulk is augmented to nearly 1700 fold, and its specific gravity reduced to about half that of atmospheric air ; it is likewise compressible to a certain extent. It is capable of absorbing or dissolving to a greater or less amount, all of the gases ; and even in the driest weather, it constantly exists in the atmosphere, in the form of invisible vapor. Pure water consists of one equivalent of hydrogen, 1, and one of oxygen, 8=9=HO. It is perfectly neutral, exhibiting neither acid nor basic properties, though capable of combining with each, and increasing their activity. It should always be kept in glass vessels. The solvent power of water is increased by heat. Water is known as Soft- Water, Hard- Water, and Mineral- Water ; the soft are always preferred to hard-waters in pharmaceutical preparations, and may be known by their forming a lather with soap, notwithstanding they may contain considerable impurities. Hard-water, contains one or several salts of lime, with other impurities, curdles soap, and is unfit for internal use, or domestic purposes. An excellent test for determining the quality of water is the tincture of soap ; in distilled water it produces no effect; in soft water, only a slight opalescence ; and in hard water, a milky appearance. We have several varieties of water, as rain, snow, spring, river, well, lake, and marsh water ; the first two are the purest, the following three come next in order, and the last is unwholesome, and ought never to be employed for domestic or medicinal purposes. Good water is limpid, without smell, and does not curdle soap ; and its transparency is but little affected by nitrate of baryta, nitrate of silver, or oxalate of ammonia. Rain and snow-waters, are distinguished from distilled water, chiefly by their holding in solution an unusual amount of atmospheric gases. To obtain either of them pure, they must be collected in large clean vessels as the rain or snow falls toward the earth; and this should be done at some distance from houses, commencing some time after they 230 Materia Medica. have fallen, in order to avoid the contamination of dust and other impu- rities in the atmosphere, which is usually present with the first fall of the rain or snow. Rain-water, (aqua pluvia) may by proper precautions be obtained tolerably pure from the roofs of houses on which it falls, by allowing the impurities to be washed away in the commencement of a heavy rain. In large cities the rain-water contains nitrogenized organic matter. Both rain and snow-waters may be applied to every domestic purpose, as well as to most chemical and pharmaceutical operations. But no water should ever be used which comes in contact with lead—for the lead becomes oxydized by the oxygen of the water, which oxide is reduced to a carbonate by the action of the carbonic acid derived from the air, and the water thus containing lead may produce the poisonous effects of that metal upon the system. The more soft and pure the water, the greater the risk. Spring-water, (aqua fontana,) is that which springs from the earth, free from large amounts of carbonic acid, or salts, and not possessing elevated temperatures ; it is the general beverage of mankind, and is applicable to all domestic purposes. Its quality depends entirely on the strata through which it flows ; those springs arising from traprocks, sandstones, transition rocks, and primitive rocks are the purest; those from alluvial strata, limestone, and coal formations are the least pure. All however contain variable traces of the salts of lime, soda, or magnesia, which vary according to the locality of the spring. River-water, (aqua fluvialis) especially when passing through alluvial countries and near great cities, contains suspended in it more or less earthy, and vegeto-animal impurities, which impair its transparency, but which in a short time will purify itself during its downward course. In countries where the rivers pass chiefly over primitive rocks, the waters are found to be almost perfectly pure. When moderately pure it is fit for all ordinary purposes, though if it contain much vegeto- animal matter, it is apt to occasion dysentery, and other affections of the bowels, and then becomes inadmissible in pharmacy. The Croton water of New York, the Schuylkill water of Philadelphia, and the Ohio river water, are, when filtered, sufficiently pure for all the purposes of phar- macy, where distilled water is not expressly required. Lake-water, in the United States, is generally a pure and wholesome water; in other instances it is similar to the river-water. Well-water, very much resembles spring-water in its qualities, its purity being proportioned to its depth and amount of use. In large cities well-water always contains nitrates, owing to the rapid oxidation of nitrogenized organic matter, which filters through the soil. These nitrates prevent the formation of any vegetable matter in water, even when long kept. A very pure water is usually obtained from the Arte- sian or overflowing wells. Aqua. 231 Marsh-water being commonly stagnant, and containing vegetable mat- ters in the process of decomposition, is unwholesome, and should never be employed for domestic or medicinal purposes. The Journal of Pharmacy of March, 1848, gives the following pro- cess of Dupasquier to ascertain whether there is an amount of organic matter held in solution in water, above the minute quantity usually present in good water: Place into a small flask one or two fluidounces of the water to be tested, and to it add a few drops of solution of chloride of gold, free from excess of muriatic acid, enough to give the water a slight yellow tint; then boil it. If the yellow tint remains unchanged, the ordinary proportion of organic matter is present; but if the liquor becomes at first brownish and afterward violet or bluish, in consequence of the reduction of the gold, the water holds a greater amount of organic matter than usual. This organic matter is of the nature of ulmin or gein. Prof. Faraday states, that "one grain of water will require for decom- position an electric current equal to a very powerful flash of lightning." The chemical action of a grain of water upon four grains of zinc, can evolve electricity equal in quantity to that of a powerful thunderstorm ; and he states, that from his experiments it would appear, that 800,000 such charges of the Leyden battery would be necessary to supply elec- tricity sufficient to decompose a single grain of water. The Leyden battery of which he speaks, consists of fifteen jars, containing 3510 square inches, or about twenty-four and a half square feet of coated glass, charged by thirty turns of a plate electrical machine, the plate being fifty inches in diameter, and of immense power, giving ten or twelve sparks an inch long for each revolution. In relation to this an author in the Philosophical Magazine remarks, that "the estimate that 800,000 discharges of the battery of fifteen jars, equal to a powerful flash of lightning, would be necessary to resolve a single grain of water into its elements, is certainly astounding, when it is recollected that, according to Prof. Faraday, the quantity of electricity that decomposes a body, is the equivalent quantity of electricity that had previously held the ele- ments of that body in combination; for he, with Davy and others, con- ceives that electricity and chemical affinity are identical powers. Hence, in one grain, that is, one drop of water, there must be naturally existing, and constituting the affinity between its oxygen and hydrogen, no less a quantity of electricity, than 800,000 charges of a battery, containing 3510 square inches of coated glass, or the equivalent of a very powerful flash of lightning. If this quantity of electricity were converted into one spark, it would be 4166 miles in length, taking Prof. Faraday's mean estimate of one charge of his battery as the basis of calcu- lation." Mineral waters, are those which present a large proportion of carbonic acid, with or without saline, alkaline, metallic, earthy and other foreign 232 Materia Medica. substances, and which exert an appreciable therapeutical influence on the animal economy. For all practical purposes, they may be conve- niently arranged into carbonated, sulphureted, chalybeate, and saline min- eral waters, for an account and list of each of which, see Appendix. When the water is elevated in temperature they are called Hot or Ther- mal springs; when of ordinary temperature or lower, they are called Cold Mineral Springs. Properties and Uses.—As a remedial agent, apart from its natural necessitous use, water internally is a tonic, diuretic, or sudorific, accord- ing to its mode of administration. Small quantities, taken cold, between 45° and 60°, and occasionally repeated, act as a tonic ; in larger doses it produces diuresis, and diaphoresis, the latter effect more especially, if the patient be kept warmly covered, and it is extensively used for this purpose in many acute diseases. Warm water, between 60° and 100°, relaxes the fibers of the stomach, and, particularly if given in large quantities, is apt to provoke nausea and vomiting. In fevers, water is a grateful drink, allaying thirst, moderating the fever, often producing sleep and relief from restlessness ; and is sufficient, unaided by other means, to effect a rapid solution of the disease, in many instances. It should never be withheld from patients laboring under febrile or inflam- matory complaints, who crave it. During the operation of a vegetable emetic, cool water at 60°, is more agreeable, and fully as beneficial in assisting the emesis, as warm. Externally, water is frequently applied as a sedative in local inflam- mations, as quinsies, sore-throats, ophthalmia, sprains and contusions, and as a means of restraining hemorrhage. Cloths wet with cold water and applied to the abdomen, have relieved severe pain in the bowels, retention of urine, etc. The cold dash or douche, has been successfully employed in delirium tremens, apoplexy, tetanus, hysteria, convul- sions, obstinate constipation, congestive, bilious and typhoid fevers. The wet sheet is much used to allay febrile and inflammatory conditions, and to promote diaphoresis. As an injection it has been efficient in habitual constipation, and excessive tympanitic distension, as well as dvsentery. Applied warm it is an excellent application to erysipelatous inflamma- tions. Ice and iced water, as a local application, are said to be very useful in burns and scalds, also in many cerebral affections. As a bath, water is also an important remedy. The vapor-bath accele- rates the circulation, produces profuse sweating, and softens and re- laxes the skin, and may be employed in a variety of cases. The hot bath has a similar effect, but is apt to be dangerous in some constitutions. The warm bath diminishes the frequency of the pulse, lessens the fre- quency of respiration and the heat of the body, and relaxes the skin. It acts as a soothing remedy, producing a disposition to sleep. It is useful in febrile and inflammatory diseases, characterized by frequent Aqua. 233 pulse, preternaturally hot and dry skin, and much restlessness ; also in spasms and convulsions of children, retention of urine, nephritic pains, and the like. It is contra-indicated in diseases of the head and chest. The cold bath acts according to its temperature and mode of application, as a stimulant, tonic, and sedative. The following are the temperatures at which baths are usually ap- plied :— Water, cold,....................................... 50° to 75° F. do temperate,................................. 75 to 85 " do tepid,..................................... 85 to 92 " do warm,..................................... 92 to 98 " do hot,....................................... 98 to 112 " Vapor, if breathed, tepid,........................... 90 to 100 " do do warm,.......................... 100 to 110 " do do hot,............................. 110 to 130 " do if not breathed, tepid,.......................... 96 to 106 " do do warm,........................ 106 to 120 " do do hot,........................... 120 to 160 " Hot air, as a sudorific,.............................. 85 to 100 " do as a stimulant,............................. 100 to 130 " In addition to the above uses of water, it has likewise other employ- ments, as follows :— The Wet Sheet Packing, or Lien Tuch of the Germans. A mattress of cotton, hair, or straw, has spread over it three or four large, thick comfortables, and over these one or two soft flannels. A linen sheet having been previously dipped in cold water, or for very delicate persons in tepid or even warm water, is lightly wrung out, so as not to drip, and spread over the whole, having under it one or two pillows for the head. The patient is made to lie upon these on his back, and is quickly and snugly enveloped in the wet sheet, over which is placed the flannels and blankets, or a light feather-bed may be thrown over the top, in case comfortables are not plenty. Care should always be taken to turn the clothing snugly and smoothly around the feet and neck; and if the feet remain cold, bottles of cold water should be placed to them. Headache is prevented or removed by the application of cold wet cloths applied to the head. The time for remaining thus "packed," varies in different cases, averaging from half an hour to an hour, depending on the effect; the body should become comfortably warm before being removed. A dis- agreeable sensation of cold is first experienced, which is soon followed by a pleasurable warmth over the whole surface, and sometimes copious perspiration, though this last is not always indicated. On coming out of the "pack," the plunge, the douche, rubbing wet sheet, or towel- washing are to be employed as the case may require. If the patient experiences a chill after coming out, a thorough rubbing, followed by fifteen or twenty minutes' dry packing, will usually obviate all injurious 234 Materia Medica. consequences. The process of packing should never be continued so long as to cause headache, languor, muscular debility or giddiness. This is said to act as a sedative, reducing the heat of the body, and excessive arterial action, and as an alterative, correcting morbid secre- tions and restoring healthy ones. In fevers, and all acute inflamma- tory disorders, it may be frequently renewed according to the degree of fever or inflammation, until the temperature and circulation are reduced to the natural standard, and the skin becomes soft and perspirable. Much sweating is not usually to be desired. In chronic diseases, it removes internal congestions, develops external circulation, produces a healthy condition of the skin, and may be used in many forms of this class of maladies. If carelessly attended to, the wet sheet may give rise to serious difficulties. When the wet sheet is applied to the trunk of the body only, as in cases of feeble persons, where there is not sufficient vitality for the whole sheet, or for other purposes, it is termed the "Half Pack Sheet." The Douche (doosh) is the application of a stream of cold, tepid or warm water, from a greater or lesser hight, and continued for a time indi- cated by its effects. The force of the stream, and time of application should be carefully adapted to the strength of the patient. Very nerv- ous persons, and those subject to determinations to the brain, should resort to it with extreme caution. A strong douche should never be applied to the head, nor should it be long continued on any one spot along the vertebral column. A douche may be vertical, oblique, hori- zontal, or ascending. The most common are in perpendicular streams one or two inches in diameter. Its effect is to arouse the activity of the absorbent system, and is hence very useful in gout, rheumatism. paralysis, chronic enlargements of the viscera, tumors, etc. The ascending douche will be found beneficial in piles, uterine dis- placements, prolapsus ani, constipation from debility, chronic enlarge- ment of the prostate gland, impotency, etc. The stream may be half an inch to an inch, and should not be forcible enough to cause absolute pain nor serious inconvenience. Warm water douches are for the pur- pose of producing relaxation of the muscles of the part acted upon, and are hence useful in rigidity of the muscles, painful swellings, chronic inflammation of the joints, neuralgia, spasmodic and bilious colic, reten- tion of urine, amenorrhea, uterine rigidity, etc. In some cases it should be followed by a momentary cold dash. The Rubbing Wet Sheet is a large sheet dipped in water, and wrung out so as not to drip. It is then suddenly thrown around the patient's body, enveloping him closely from the neck to the feet, and the body is then rubbed for about five minutes by the hands of the attendant on the outside of the sheet. It is to be followed by rubbing with dry towels. This produces a strong and general determination to the whole surface, Aqua. 235 and is applicable in all cases where a strong determination is desired from internal organs or surfaces to the skin. It will be found valuable in the early stages of bowel complaints, diarrhea, dysentery, colic, fevers, etc.; it is likewise useful for exhaustion following mental exertion, many forms of insanity, delirium tremens, nightsweats, wakefulness, night- mare, etc. When the sheet is employed drippingly wet, (the dripping sheet) a large tub or pan is necessary for the patient to stand in, to avoid wetting the floor. The Hip or Sitz Bath is a common tub, in which the patient sits so as to have the water cover the hips and lower part of the abdomen. A vessel made for the purpose, with a back to rest against is more conve- nient. The water may be of any temperature, and the time of applica- tion varies from five to thirty minutes. According to its application it is tonic, derivative, or sedative. Tonic when applied from five to fifteen minutes ; derivative when extended from fifteen to thirty minutes ; and sedative according to its effects. Derivative hip baths should not be earned to the point of producing paleness or lividity of the lips, shiver- ings, nausea, faintness, or headache, and according to the effect desired, and the coldness, torpor, and debility of the patient, indicate that the quantity of water should be lessened, or its temperature elevated. It is useful in debility, irregularity, obstruction, and torpor of the organs of the pelvis and lower part of the abdomen. A blanket is generally thrown around the patient during this bath. The Shallow Bath is a circular, or oval tub, raised about twelve inches from the floor, and with water in it from four to six inches deep. The patient sits in this, while the attendant sprinkles his head, and rubs his chest, abdomen, and back. It may be employed from one to thirty minutes, and should be followed by a good dry rubbing. It is used at a temperature from 60° to 75°, and is excellent in cutaneous affections, and other cases where a mild derivative, or moderately-sedative influ- ence is desired. The Plunge Bath may be any vessel or place, the water being from 55° to 65°, which will allow the patient to plunge into it, head, or feet foremost as he fancies, or to quickly immerse the whole body up to the neck. The time for remaining in it, varies from a few seconds to two or three minutes, or in high fever, to ten or fifteen minutes. It is generally taken after the sweating process, and after the wet sheet, when the patient can bear the exertion; in these cases the sheet is not to be removed until at the plunge. It is very useful in all febrile and chronic affections, but should be employed with care, or avoided altogether in consumptive, and dropsical patients, and those laboring under organic diseases of the heart. These are the principal applications of water in Hydropathic practice ; yet there are several others of a useful character, as the Foot Bath, 236 Materia Medica. the Head Bath, the Shower Bath, the Vapor Bath, etc., the mode of application of which are generally well understood, as well as their effects. Cold water may likewise be used in form of a bandage or girdle, by applying one or more folds of linen wet in cold water, to the part affected, or around the abdomen, and covering it with a dry cloth or other material to retain the heat. The wet girdle or abdominal wrapper or compress, is applied around the abdomen in all acute diseases of the abdominal viscera. The bandages are applied warm or cold, according to the indications they are intended to fulfill. Mineral waters vary in their effects upon the system, according to their constituent combination. The acidulous waters are powerful and diffusive stimulants of the nervous and circulatory systems, likewise diuretic. Generally useful in dyspepsia, passive dropsy, chronic diseases, chlorosis, and phosphatic gravel ; contra-indicated in recent palsy, apo- plexy and active hemorrhages and inflammations. Alkaline waters are antacid, antilithic, and diuretic. Useful in gout, gravel and stone. Purgative waters also possess diuretic properties, and are useful in all cases where laxatives are required. Chalybeate waters are tonic, and used in dyspepsia, all kinds of chronic cachexies, gout, and chronic diseases generally. Sulphurous waters are stimulant, dia- phoretic, diuretic and emmenagogue, and are found beneficial in chlorosis, rheumatism, dysmenorrhea, secondary syphilis, chronic cuta- neous diseases, and deranged conditions of the stomach and liver. They are contra-indicated in plethora, determination to the head, and active hemorrhages and inflammations. Waters which contain iodine or bro- mine, have been found of some use in goitre and scrofula. Sea-water internally is an emetic and purgative; as a bath it has all the effects of an ordinary cold bath, with the addition of exerting a more stimulant action on the skin than fresh water, owing to its saline contents. It has been found serviceable in rickets, enlargement of glands, or joints, some chronic cutaneous eruptions, scrofula, and many chronic diseases. ARALIA HISPIDA. Dwarf Elder. Nat. Ord.—Araliaceae. Sex. Syst.—Pentandria Pentagynia. bark of the root. Description.—Aralia Hispid a is a perennial plant, with a low stem, from one to two feet high, the lower part woody and shrubby, and thickly beset with sharp, stiff bristles, the upper part herbaceous and branching. The leaves are bipinnate ; the leaflets oblong-ovate, acute, cut-serrate; umbels many, simple, globose, axillary and terminal, on long Aralia Nudicaulis. 237 peduncles, followed by bunches of dark-colored, nauseous berries. It flowers from June to September. The whole plant exhales an unpleas- ant odor. History.—This is a low undershrub, growing from New England to Virginia, in fields, hedges, rocky places, and along the roadsides. The fruit is round, black, and one-celled, containing three irregular-shaped seeds. The bark of the plant is employed in medicine, but that of the root is the most active. It yields its virtues to water. It is known in various sections of the country by the names of Wild Elder, Bristlestem- Sarsaparilla, etc. Properties and Uses.—The leaves in warm infusion are sudorific. The bark is diuretic and alterative. Very valuable in dropsy, gravel, sup- pression of urine, and other urinary disorders. The juice and decoction of the fresh roots are said to be emetic and hydragogue, and have been found efficacious in dropsy. Dose of decoction, two to four ounces, three times a day. Off. Prep.—Decoctum Araliae. ARALIA NUDICAULIS. Small Spikenard. Nat. Ord.—Araliaceae. Sex. Syst.—Pentandria Pentagynia. THE ROOT. Description. — Aralia Nudicaulis is an indigenous perennial plant, with one leaf and one flower-stem, springing together from the root, or from a very short stalk, and seldom rising two feet in hight. The root is large and fleshy. The leaf, which stands upon a long foot- stalk, is either tri-ternate, or tri-quinate, with oblong-oval, acuminate leaflets, rounded at the base, serrate on the margin, and smooth on both surfaces. The flower-stem or scape is naked, shorter than the leaf, and terminating by three small umbels, each consisting of from twelve to thirty yellowish or greenish flowers. The fruit consists of small round berries, about the size of the common elder. The root is horizontal, creeping, several feet in length, more or less twisted, as thick as the little finger, and of a yellowish-brown color externally. History.—This plant, sometimes known as American, Wild, or False Sarsaparilla, is indigenous, growing in rocky woods and rich soils in the northern and middle States. The root, which is the officinal part, pos- sesses a fragrant balsamic odor, and a warm, aromatic, sweetish taste. It yields its virtues to water or alcohol. Properties and Uses. — Alterative, and gently stimulant. Used in decoction or syrup as a substitute for Smilax Sarsaparilla, in cutaneous, 238 Materia Medica. rheumatic and syphilitic affections ; also in pulmonary diseases. Exter- nally, a strong decoction of it is useful as an application to zona (shingles) and as a stimulant wash to old ulcers. The Aralia Racemosa, Pettymorrel, or Spikenard, has a herbaceous, widely-branched, smooth stem, three or four feet in hight, dark-green, or reddish, and arising from a thick aromatic root; the leaves are decom- pound ; the leaf-stalks divide into three partitions, each of which bears three or five large, ovate, pointed, serrate, slightly downy leaflets. Umbels numerous, small, arranged in branching racemes from the axils of the leaves or branches. It flowers in July, and grows in rich wood- lands. The root is large, spicy, and aromatic, and possesses properties similar to that of the A. Nudicaulis; it is much used in pulmonary affections, and enters into the compound syrup of spikenard. Off. Prep.—Syrupus Araliae Compositus. ARALIA SPINOSA. Prickly Elder. Nat. Ord.—Araliaceaa. Sex. Syst.—Pentandria Pentagynia. BARK. Description.—The Aralia Spinosa, sometimes called Toothache Tree, Southern Prickly Ash, and Angelica Tree, is an indigenous arborescent shrub, with a crooked, shrubby, unbranched stem, which is naked and prickly below, with the leaves crowded at the summit of the stems, somewhat like the palms ; it is generally not more than ten to twenty feet high, but in the south it sometimes attains to even sixty feet. The petioles are very long and prickly; the leaves are bipinnately compound, composed of ovate-acuminate, serrate, mostly glabrous leaflets, which are somewhat glaucous beneath. The umbels are in large, much branched panicles, with small, few-leaved involucres. The flowers are small, white, with connivent styles, and appear in August and Septem- ber ; sometimes they are polygamous, as the number of berries bears no proportion to the flowers. The fruit is a blackish, juicy berry. History. — The Prickly Elder is found chiefly in the southern and western States, and is much cultivated in gardens as an ornamental plant: It grows in low, damp, fertile woods. The bark, root, and berries are medicinal, but the first is principally employed; it yields its properties to alcohol or water. It is thin, of a grayish color externally, and a yellowish white within, with a peculiar but aromatic odor, and a bitterish, pungent, acrid taste. Properties and Uses.—Aromatic, stimulant, diaphoretic and alterative; the fresh bark is emetic and cathartic. The tincture has been used in Arctium Lappa. 239 chronic rheumatism, syphilis, and in some cutaneous diseases. The warm infusion will vomit, unless made very weak. The tincture of the berries has been found advantageous in violent colic, and rheumatism, and from their pungency, have been found beneficial in relieving tooth- ache. Much use was made of this bark by the Eclectics in Cincinnati, during the cholera of 1849-50, in cases where cathartics were required, but where the action of every purgative was very difficult to control; the preparation was composed of one drachm compound powder of Jalap, one drachm Aralia Spinosa, and two drachms compound powder of Rhubarb. Given in powder, in half teaspoonful doses ; or the pow- der was infused in half a pint of boiling water, of which infusion, when cold, a tablespoonful was given every half hour. In no case in which it was given, did it produce a tendency to looseness or choleraic dis- charges. It is a powerful sialagogue, and is valuable in diseases where the mouth and throat are dry and parched, as a very small portion of the powder will produce a moisture and relieve difficult breathing; also useful in sore-throat.

Description.—By De Candolle this plant is named Lappa Minor, and by Gaertner, Lappa Major. It is a biennial plant, with a fleshy, tapering root, a foot or more in length, of a brown color externally, white inter- nally, furnished with thread-like fibers, and having withered scales near the summit. The stem is erect, three or four feet high, succulent, pubes- cent, branching, bearing very large, cordate, denticulate leaves, of a dark-green color above, whitish and tomentose beneath, and standing on long footstalks. The flowers are purple, globose, in panicled heads. The involucre consists of imbricated scales, with a horny, hooked ex- tremity, by which they can attach themselves to clothes, and the hair or wool of animals. The florets are all perfect, five-cleft, with a ten-nerved tube. The stamens have papillose filaments, and their anthers are ter- minated by filiform appendages, and have subulate tails at the base. The stigmas are free at the apex, diverging and curved outward. The receptacle is somewhat fleshy, flat, and furnished with stiff subulate fringes. The achenia are oblong, smooth, with a rough, prickly pappus. The seeds are quadrangular. 240 Materia Medica. History.—Burdock is a native of Europe, and grows abundantly in this country, among rubbish, on road-sides, and cultivated grounds. The root and seeds are the officinal parts ; the first loses about four- fifths of its weight by desiccation ; it should be collected in the spring. The odor of the root is weak and unpleasant, the taste sweetish, mucila- ginous, slightly bitter and astringent. It contains sugar, gummy ex- tractive, a large quantity of inulin, some salts, etc. Water or diluted alcohol extracts its properties. The seeds are aromatic, bitterish, and somewhat acrid. Properties and Uses.—Alterative, diaphoretic, diuretic, and aperient. Useful in scorbutic, syphilitic, scrofulous, gouty, leprous, and nephritic diseases. To prove effectual its use must be persevered in for a long time. The seeds are more diuretic than the root, and are said to be likewise a more useful alterative; they are principally used in nephritic complaints. Externally the leaves or their juice in the form of an oint- ment, have been employed with advantage in cutaneous diseases, and obstinate ulcers. Dose, of a decoction or syrup, half a pint three times a day. Off. Prep.—Infusum Arctii; Extractum Arctii; Syrupus Sarsaparillae Compositus. ARCTOSTAPHYLOS UVA URSI. Uva Ursi. Nat. Ord.—Ericaceas. Sex. Syst.—Decandria Monogynia. LEAVES. Description.—This plant, known also as Bearberry, Upland Cranberry, etc., is a low, evergreen shrub, with a perennial, long, fibrous root; the stems are procumbent, round, wood)', and branched, covered with a smooth, deciduous bark. The leaves are numerous, alternate, evergreen, obtuse, obovate, entire, coriaceous, smooth, dark-green and wrinkled above, reticulated and paler beneath, acute at base, and supported on short petioles. The flowers grow in small clusters at the extremities of the branches, each on a short, red, reflexed peduncle, furnished with several minute bracts; they are usually six to twelve on each branch, drooping, and of a pale rose color. The calyx is small, obtusely five- toothed, persistent, and of a reddish color. The corolla is ovate or urceolate, smooth, white with a reddish tinge, transparent at the base, contracted at the mouth, hairy inside, with five short, reflexed segments. The stamens are ten, with subulate downy filaments inserted at the base of the corolla, and reddish incumbent anthers, of two oval cells, opening by two terminal pores, and furnished with a pair of short horns or spurs. Arctostaphtlos Uva Ursi. 241 The ovary is roundish, bearing a cylindrical erect style, with a simple stigma. Disk a black indented ring. Fruit small, globose, smooth, depressed, scarlet, containing a mealy pulp of an austere or insipid taste, and five almost united angular seeds. This plant is the Arbutus Uva Ursi of Linnaeus, and Willdenow, from which it was separated by Sprengel, principally on account of the difference of its berry. History.—The Uva Ursi is a perennial evergreen, common in the northern part of Europe, Asia, and America, growing on barren, gravelly hills, and elevated sandy plains. It flowers from June to Sep- tember, and ripens its berries during the winter. The leaves are the only part used in medicine, they should be collected in autumn, and the green leaves only selected. They are about an inch long, and two to three lines wide, often spatulate in form. They are sometimes adul- terated with the leaves of the whortleberry or cowberry, Vaccinium Vitis Idcea, from which they may be detected, by the rounder shape, and the revolute edges of the Vaccinium, and by their being dotted beneath instead of reticulated as in the genuine leaves. Leaves of the Chimaphila Umbellata may be determined by their greater length, their cuneiform lanceolate shape, and their serrate edges. The leaves of Uva Ursi when dried have a faint odor like hay, and a bitterish, strongly astringent taste, which becomes finally sweetish. Their powder is of a yellowish-brown color. Analysis has discovered in them gallic and tannic acids, resin, gum, bitter extractive, some salts, volatile and fixed oils, lignin, and a peculiar principle, called ursin, which contains its diuretic power. The leaves yield their properties to water or alcohol. Ursin, is said by J. C. C. Hughes, to be prepared as follows ; mace- rate one pound of the leaves of Uva Ursi in water for twelve hours, and displace until two quarts of liquor are obtained. Then precipitate the tannin with a solution of gelatin, and filter. Evaporate the filtered liquor to dryness, and dissolve the remaining extract in strong alcohol, and treat it with purified animal charcoal for twenty-four hours. Again filter, evaporate, and redissolve in absolute alcohol, and treat again with puri- fied animal charcoal for twenty-four hours; filter and crystallize by spontaneous evaporation. Press the crystals, redissolve in absolute alcohol, treat with animal charcoal, filter, and again crystallize by spon- taneous evaporation. The crystals are colorless, transparent, needle- shaped prisms, soluble in alcohol, ether, and dilute acid, but insoluble in fixed and essential oils. Subacetate of lead and carbonate of potassa precipitate its aqueous solution ; lime-water, and tincture of chloride of iron do not affect it. It is neutral to test-paper, and combustible. One grain acted as a powerful diuretic. Arbutin and Arctuvin have also been obtained from the leaves by Kawalier, but their therapeutical influ- ences are not positively known. 16 242 Materia Medica. Properties and Uses.—Uva Ursi is an astringent, tonic, and diuretic. As an astringent it is applicable to all the purposes for which astringents are used, as in chronic diarrhea and dysentery, diabetes, and menorrha- gia. Its principal use however is in chronic affections of the kidneys and urinary passages, in vesical catarrh, chronic gonorrhea, gleet, leucor- rhea, incontinence of urine, strangury, and in excessive mucous dis- charges. It changes the color of the urine, and its astringent principle has been detected in that secretion, also reputed efficacious as an anti- lithic in calculous affections. In gonorrhea, with bloody and mucous dis- charges, and pain in the vesical region, it speedily allays all these unpleasant symptoms. Dose of the powder ten to sixty grains ; of the decoction, one to three fluidounces, made by boiling one ounce of Uva Ursi with a pint and a half of distilled water to a pint; of the extract five to fifteen grains. Off. Prep.—Decoctum Uvae Ursi. ARGENTI NITRAS. Nitrate of Silver. Lunar Caustic. Preparation.—Mix Nitric Acid, five fluidrachms with distilled water two fluidounces, and dissolve silver, in small pieces, one ounce, in the mixture on a sand-bath; then gradually increase the heat, so that the resulting salt may be dried. Melt this in a crucible over a gentle fire, and continue the heat until ebullition ceases ; then immediately pour it into suitable molds. It should be kept in bottles with glass stoppers, as corks quickly decompose it—especially its solution. If the heat be raised to too high a temperature, the salt decomposes aud turns black. Chemical Properties. — If the solution be allowed to crystallize by evaporation and cooling, it assumes various forms, as hexangular or rhombic tables, or right rhombic prisms, of a transparent or colorless appearance, which turn black when exposed to the light, or to the direct rays of the sun. The stick or rods of the salt, are at first white, but from the action of light, become grayish, and when broken they present a crystalline texture with a radiated surface. They differ from the crystallized nitrate only in form and color, and do not contain any water of crystallization, as has been supposed. Nitrate of silver is a very heavy salt, having an intense, persistent, and bitter metallic taste ; it fuses at 426°, and undergoes decomposition at about 600°, parting with its oxygen and nitrous acid, and leaving the metal in a state of purity. It is soluble in its own weight of cold-water, and in four parts of alcohol. It stains the skin, and almost all organic substances of a dark or black color, and corrodes the soft tissues. These spots may be removed by placing on them a few drops of tincture of Argenti Nitras. 243 iodine, which converts the salt into an iodide of silver ; this is to be dissolved by a solution of hyposulphite of soda, made of the strength of half a drachm to a fluidounce of water, after which the spots may be washed out with warm water. Indelible ink for marking linen, etc., owes its character to this salt; the common formula for this preparation is as follows: take of nitrate of silver five scruples, gum arabic two scruples, sap-green one scruple, distilled water one fluidounce ; mix together ; with this the linen is to be marked, having had the following preparation or mordant previously applied; take of carbonate of soda half an ounce, distilled water four ounces. An ink has, however, been recently used, which does not require a mordant, flows freely from the pen, does not require a strong or long continued heat to develop the black mark, and which will not destroy the texture of the finest cambric. It is prepared thus ; dissolve nitrate of silver one ounce, in a sufficient quantity of distilled water; also dissolve crystallized carbonate of soda one ounce and a half, in sufficient distilled water. Mix the two solutions; a precipitate ensues which must be collected and washed on a filter. Introduce the washed precipitate, still moist, into a Wedgewood's-ware mortar, and add to it tartaric acid eight scruples, rubbing them together until effervescence has ceased; add strong liquor ammonia in sufficient quantity to dissolve the tartrate of silver (about two ounces) ; then mix in archil, half a fluidounce, white sugar four drachms, powdered gum arabic twelve drachms, and add distilled water sufficient, if required, to make six fluidounces of the whole mixture. Nitrate of silver, especially in solution, should always be kept in bottles with glass stoppers, as cork quickly decomposes it. It is an anhydrous salt, and is composed of 116 parts or one equivalent of pro- toxide of silver, and 54.15 parts, or one equivalent of nitric acid, (AgO+ NOa), and is incompatible with almost all spring and river-water, on account of the common salt usually contained in them, with soluble chlorides, sulphuric, hydro-sulphuric, muriatic, and tartaric acids, and their salts, with the alkalies and their carbonates, lime-water, and astrin- gent vegetable infusions. This salt is liable to adulterations, among the principal of which are the nitrates of lead, copper, zinc, and potassa; or it may contain free silver, by having been exposed to too high a heat during fusion. It almost always contains a small proportion of free silver when in sticks, which may be known by the undissolved black powder present in its solution in distilled water. Precipitate a solution of nitrate of silver by an excess of chloride of sodium ; if this precipitate is entirely soluble in ammonia the salt is pure ; if not, lead is present. Sulphureted hydrogen passed through the liquid, after having removed the above precipitate, gives a white precipitate if zinc be present, and black if there be any copper. Nitrate of potassa may be suspected when a colorless fracture 244 Materia Medica. is presented upon breaking the sticks, and when the salt is entirely soluble without the black powder sediment. It may be detected by precipitating a solution of the suspected salt with an excess of muriatic acid; pass sulphureted hydrogen to remove any metals present, filter the solution, and evaporate,—if pure it will all evaporate—if nitre be present, it will be left, and easily recognized by its properties. Impurities, without regard to their character, may be ascertained by dissolving 29 grains of the salt in a fluidounce of distilled water, to which 9.12 grains of muriate of ammonia are to be added; briskly agitate the mixture for a few seconds, and then allow it to rest, until precipitation has ceased; then if, on the addition of more muriate of ammonia, no farther precipitation ensues, the salt is impure. Properties and Uses.—A certain class of practitioners, consider this salt as a tonic and antispasmodic, and employ it to fulfill these indica- tions, in epilepsy, chorea, angina pectoris, etc., as well as administering it in intestinal ulceration during typhoid fever, diarrhea, etc. However, it is never used as an internal agent by Eclectics, but as an escharotic, either dissolved in distilled water, or in the solid form. When employed in solution, its strength is varied, according to the condition of the parts to be acted upon, and the character of the affection—from five grains to eighty to the fluidounce of water. It has been beneficially applied to ulcers, warts and other excrescences, fungous flesh, chancres, and in ulcers of the cornea, some forms of ophthalmia, fetid discharges from the ear, aphthous affections of the mouth, and spongy gums. It has like- wise been recommended as a topical remedy in erysipelas and various other external inflammations, leucorrhea, gonorrhea, uterine ulcerations, granulations, and excoriations, and stricture of the urethra; also in ring- worm, and some other forms of chronic cutaneous diseases. A solution of it is highly recommended in chronic laryngitis, pharyngitis, pertussis, asthma, and venereal ulceration of the throat, applied by means of a sponge fastened to one end of a piece of whalebone. The solid stick is sometimes used in ulcerations of the throat, and chilblains. If the pain be excessive from the application of the nitrate, it may be at once relieved by washing the parts with a solution of common salt, which decomposes it, and converts it into the insoluble chloride of silver. The same article is an antidote to its poisonous effects when taken internally in too large doses. ARISTOLOCHIA SERPENT ARIA. Virginia Snakeroot. Nat. Ord.—Aristolochiaceae. Sex. Syst.—Gynandria Hexandria. ROOT. Description. — Aristolochia Serpentaria, also called Snakeroot, and Snakeweed, is a perennial herbaceous plant, with a short, horizontal, Aristolochia Serpentaria. 245 knotty, brown caudex, which sends out numerous, slender fibers. The stems are erect, flexuous, round, jointed, slender, about eight or ten inches in hight, of a reddish or purple color near the base, and rise singly or severally from the same root. The leaves are alternate, petio- late, oblong, entire, acuminate at apex, cordate, and three-nerved at base, surface more or less pubescent, and of a pale yellowish-green color. The flowers proceed from the joints near the root, and stand singly on long, slender, round, jointed peduncles, which are somewhat scaly, and curve downward so as nearly to bury the flower in the earth, or among the decayed leaves ; they have a stiff, leathery texture, and a dull brownish-purple color. The peduncle which supports them has one or more bracts, and gradually enlarges into a furrowed obovate ovary. The calyx is of a dull-purplish, or reddish color, with a long, contorted tube, bent in the form of the letter S, swelling at its two extremities, having its throat surrounded by an elevated edge or brim, and its border expanded into a broad, irregular margin, forming an under and Upper lip, which are closed in a triangular manner in the bud. Corolla none. Anthers six or twelve in number and sessile, oblong, obtuse, and attached to the sides or under part of a large, round, sessile stigma, which is divided into six parts, and supported by a short fleshy style upon an oblong, angular, hairy, inferior germ. The fruit is an obovate, hexan- gular, six-celled capsule, with numerous small, flat seeds. History.—Several species of Aristolochia are confounded in the drug market with the above, but as they are all nearly identical in medical properties, it is of but little importance; still a brief notice of them may be proper: A. Hirsuta.—Stem flexuous, jointed, erect, pubescent; leaves alternate, large, cordate, rounded, obtuse, upper ones abruptly acuminate, very pubescent, with prominent veins; peduncles sub-radical, scaly, one- flowered, hirsute. Calyx also pubescent. This species grows in the Southern States, to which market it is more common, being seldom brought to the north; the roots resemble in taste and color, the A. Serpentaria. A. Hastala, of Nuttall, or A. Sagittata, of Muhlenberg.—Stem flexu- ous, simple, erect; leaves mostly subcordate, hastate, acute, or attenu- ated, sublanceolate, auriculate ; peduncles nearly all radical; lip of the corolla ovate. Some doubt has been expressed about viewing this as a distinct species ; it grows in the Southern States, and is frequently found mixed with the officinal plant. A. Reticulata. — Stems numerous, short, slender, round, flexuous, jointed, simple, but sometimes branched near the root; when young very pubescent, but slightly villous when old. Leaves on short, villous peti- oles, oblong, cordate, large, obtuse, reticulated with very prominent 246 Materia Medica. veins, and villous on both sides, especially upon the veins. Peduncles subradical, hairy, scaly, several-flowered. Flowers on short pedicels, small, purplish, very pubescent. Capsule hexagonal, deeply sulcate, somewhat hirsute. This species is one of recent introduction, and is much in use; it is derived from Louisiana, Arkansas, and other south- western locations; it differs from the officinal root, in having larger fibers and which are less interlaced, but is fully equal to it as a medicine. A. Tomentosa.—Stem twining, ascending to the tops of the tallest trees; leaves roundish, cordate, villous beneath; peduncles solitary, axil- lary, ebracteate; calyx densely villous; limb trifid, greenish-yellow, orifice oblique and gaping; margin elevated, dark-purple, rugose; inner part of tube white, with purple spots ; stigmas three. This species is found in Carolina and the south-western States ; its root is thick, creep- ing, and coarser than the officinal, and is less aromatic than that of the other species just named. The Aristolochia Serpentaria is found in the middle, southern, and western States, growing on hill sides, and in rich, shady woods; it flowers in May and June. As found in the shops, the root is in tufts of slender, long, matty brittle fibers, attached to a short, knotted, rugged head. The color of the recent root is yellowish, but becomes brown by age ; its powder is grayish. The odor is pungent, camphoraceous, and agreeable, and the taste warm, bitter, and also camphoraceous. Water, alcohol, or proof spirit, extracts the medical principles ; its alcoholic tincture being greenish, its aqueous infusion yellowish-brown. Analysis has found in it, a green, fragrant oil, a yellowish-green resin, extractive, gum, albumen, lignin and some salts. The oil exists more largely in the A. Reticulata, which is the most powerful of this family of plants. Virginia Snakeroot is sometimes adulterated with the roots of Spigelia Marilandica, and the young roots of Polygala Senega ; the first may be known by their want of the bitter taste, as well as by the difference in the stem and leaves, when present; the latter, by their difference in odor and taste, by being single, and by the projecting line running from one end of the root to the other. Properties and Uses.—Stimulant tonic, diaphoretic, or diuretic, accord- ing to the manner of its administration. In warm infusion it produces diaphoresis, and is beneficial in adynamic eruptive fevers, where the eruption is tardy, or has receded. In typhoid febrile conditions, in cases where active stimulation cannot be borne, it will be found very available. It has been employed successfully in periodic fevers in conjunction with sulphate of quinia. As a gargle the infusion is sometimes valuable in malignant sore-throat. In dyspepsia it has been employed as a tonic, and has proved useful in amenorrhea. If taken too long it occasions gripings, nausea, vomiting, and dysenteric tenesmus. Long boiling Arnica Montana. 247 impairs its virtues. A cold infusion is useful in convalescence from fevers.

Description.—Arnica Montana, is a perennial, herbaceous plant, with a horizontal, woody, blackish or brownish root, which terminates abruptly at the lower end, and which is furnished with many long, slender, dark-colored fibers. The stem rises about a foot in hight, is simple, obscurely-angled, striated, rough, hairy, and terminates in one, two, or three upright peduncles, each bearing one very large flower of a deep yellow color, somewhat tinged with brown. The radical leaves are ovate, entire, ciliated, and obtuse ; the cauline ones are lanceolate, and in opposite pairs ; both are bright-green, and slightly pubescent on their upper surface. The involucre is cylindrical, and composed of fifteen or sixteen rough, hairy, lanceolate scales, of a dingy-green color, but purple at the points. The disk florets are very numerous, tubular, with a five- lobed limb ; those of the radius, about fourteen, ligulate, striated, three- toothed, and hairy at the base. The achenia are oblong, blackish, hairy, and crowned with a straw-colored capillary pappus. History. — This plant is a native of the mountainous districts of Europe and Siberia, in moist, shady situations, flowering in June and July; it is likewise found in the northern regions of this continent, west of the Mississippi. The flowers, leaves, and root, have been used in medicine, but the flowers are generally preferred. When fresh, the whole plant has a disagreeable odor, very strong when fresh, and excit- ing sneezing; the taste is acrid, bitterish, and permanent. Its virtues are extracted by water. Analysis has detected in the flowers, gallic acid, gum, albumen, yellow coloring matter, an odorous resin, a blue volatile oil, some salts, and a bitter, acrid matter, supposed to be iden- tical with cytisin, the bitter principle of Cytisus Laburnum. Cytisin is a yellow substance, of a bitter, nauseous taste, deliquescent, readily soluble in water and dilute alcohol, less soluble in strong alcohol, and insoluble in ether. Five grains of it are powerfully emetic and cathartic. 248 Materia Medica. Arnicina is obtained from the flowers, by subjecting them to a process similar to that by which lobelina is extracted from lobelia inflata. It has a decided alkaline reaction, and combines with acids, forming a series of salts. It has a slightly bitter, but not acrid taste, with an odor of castor, and from the aqueous solutions of its salts, it is precipitated by tincture of galls in somewhat dense flocks ; it is more readily soluble in alcohol and ether, than in water. A high temperature decomposes it, which also obtains when subjected to the action of caustic alkalies. It has not yet been employed in medicine, though it probably possesses the active principles of the Arnica in a concentrated form. Properties and Uses.—In large doses, it causes heat in the throat, nausea, vomiting, spasmodic contractions of the limbs, difficulty of res- piration, and sometimes inflammation of the alimentary canal, and coma. Its poisonous effects are best counteracted by the free use of vinegar, or other dilute vegetable acid. In small doses, it accelerates the pulse, increases the perspiration, excites a flow of urine, and is said occasionally to cause headache and giddiness. In Germany, it is esteemed as a stimulant in typhoid fever and other adynamic febrile diseases, in chronic palsy, and amenorrhea; also, as a tonic in chronic rheumatism, and as a tonic and diuretic in the asthenic forms of dropsy. In intermittent fever it has proved very suc- cessful, also, in nyctalopia and amaurosis; and is reputed to be highly serviceable in that disordered condition of the system which succeeds concussion of the brain, from falls, blows, etc. It has also been recom- mended in diarrhea, dysentery, nephritis, gout, chlorosis, and almost every disease where there is debility, torpor, or inactivity of function. Externally, it is used in the form of a fomentation, or diluted tincture of the flowers, both to prevent and discuss local inflammations, and to remove ecchymosis. Dose of the powder, five to ten grains, two to four times a day; of the infusion, made by adding half an ounce of the flowers to a pint of water, from half an ounce to an ounce ; of the extract, which is an excellent form of administration, from five to ten grains, four or five times a day. In preparing an infusion of the flowers, they should be loosely tied in a bag, in order to prevent the down or fine fibers from getting into the infusion, or else they will cause troublesome irritation of the throat, nausea, and vomiting.

Description.—Artemisia Absinthium is a perennial suffruticose plant, with a woody root branched at the crown, and having numerous fibers below. The whole herb is covered with close, silky hoariness ; the stems are numerous, bushy, growing from one to two feet in hight, round fur- rowed, and panicled at their summit. The lower portion of the stem lives several years, and annually sends up herbaceous shoots, which perish in the winter. The radical leaves are doubly or triply pinnatifid, with lanceolate, obtuse, dentate divisions; the cauline ones, doubly or simply pinnatifid, with lanceolate, somewhat acute divisions ; floral leaves lanceolate; all are canescent. The flowers are of a brownish-yellow color, hemispherical, pedicelled, nodding, and in erect racemes ; florets of the disk numerous ; those of the ray few. External scales of involucre, linear or lanceolate, silky; the inner broad, rounded and scarious. Styles very deeply cloven. Receptacle convex, clothed with fine up- right hairs. History.—A native of Europe, but cultivated in this country. It flowers in July and August. The whole plant has a strong, fragrant odor, and an intensely bitter, aromatic taste. Alcohol, or water, takes up its active principles. It contains a volatile, bitter, acrid oil, absinthic acid, several salts, etc. Absinthine, the bitter principle of A. Absinthium, may be obtained as follows : Exhaust the dry herb, with alcohol of 0.863, and distil the clear liquid to the consistence of a syrup, transfer the residue into a glass-stoppered bottle, and shake it well with ether. After some time this separates with a yellowish-brown color ; and this treatment with ether is to be repeated until it no longer has a very bitter taste. The ethereal liquid is to be distilled in a water bath ; the residue will consist of a viscid mixture of a blackish-brown acid resin, and absinthine. Treat it with water to which a few drops of ammonia have been added, and the black smeary resin will be principally taken up, and the greater portion of the absinthine be left behind. In proportion as it becomes purer it acquires a pulverulent form. On adding a further quantity of ammonia, the absinthine is also dissolved ; but on triturating with con- centrated ammonia, far less passes into solution, because the compound of ammonia with absinthine is very sparingly soluble in ammonia. To remove the ammonia, digest it with dilute hydrochloric acid, then wash it with water, dissolve it in alcohol, and add solution of acetate of lead to it as long as any turbidity results, then filter, and pass sulphureted 250 Materia Medica. hydrogen into the liquid to decompose the excess of the lead salt. The alcoholic solution is to be filtered from the sulphide of lead, mixed with a small quantity of water, and allowed to evaporate slowly in a warm place when the absinthine separates in yellow resinous drops. These are soft, and when mixed with water, become coated with an opake membrane, and in the course of some weeks all the drops become con- verted into hard masses, which are jagged and rough externally, and internally are radiate and indistinctly crystalline. Absinthine thus obtained is yellow, or brownish -yellow; its powder is yellowish, of a faint, disagreeable, bitter odor of wormwood, an intensely bitter taste, and dissolves readily in alcohol, concentrated acetic acid, solutions of ammonia, and caustic potassa, sulphuric and hydrochloric acids. It is less soluble in ether, hardly at all in water, but melts in boiling water. It has not been much used in medicine, but probably possesses the medicinal principles of the plant, and may be found tonic, hepatic and anthelmintic. Properties and Uses. — Anthelmintic, tonic, and narcotic. Used in intermittent fever, jaundice, and worms. It is also used to promote the appetite in atonic dyspepsia, amenorrhea, chronic leucorrhea, obstinate diarrhea, etc. Combined with a fixed alkaline salt, it proves powerfully diuretic. Externally it is very useful in fomentations for bruises and local inflammations, and has also been advised as an external application in chronic affections of the abdominal viscera, either in the form of tincture, infusion, or poultice. In large doses, wormwood produces gas- tric irritation, and excitement of the circulation. Dose of the powder, ten to twenty grains; infusion, one to two ounces. The Artemisia Abrotanum (southernwood) A. Santonica, and A. Vul- garis, (mugwort) possess similar properties. The A. Vulgaris, has been reputed beneficial in epilepsy, hysteria, and amenorrhea. Santonin, or Santonicin, is a peculiar white crystallizable principle, derived from the A. Santonica, and some other species; it is soluble in ether and alcohol, and is very efficacious as a vermifuge, given in doses of three or four grains, twice a day. The high price of santonin, and the difficulty experienced in obtaining it pure, has induced M. Gaffard to endeavor to obtain from the wormseed a product which may possess the advantages of the former, and at the same time be free from the objections to the use of the latter. This product he calls Brown or Impure Santonin; it is obtained as follows : Take of Aleppo wormseed three ounces ; car- bonate of potassa one ounce; slaked lime, sifted, half an ounce; water from three to three and a half pints. Place the mixture on the fire, stirring occasionally with a wooden spatula; let it boil for half an hour; on removing it from the fire, pass it with expression through a linen cloth; let it settle, decant and add hydrochloric or nitric acid until it reddens litmus without being sensibly acid to the tongue. Allow it to rest, pass it through a filter previously moistened, or through a piece of close Artemisia Absinthium. 251 canvas, and allow the product which remains on the filter to dry in the open air, until it acquires the consistence of firm butter. This product, which is a mixture of santonin, resin, and essential oil, will answer for the various pharmaceutic forms in which the practitioner may wish to exhibit it. M. G. gives it in the form of lozenges, composed as follows : Place in a marble mortar, brown santonin three drachms; add by degrees, and with constant trituration, powdered sugar thirteen ounces, mixed with powdered gum one ounce and a half, and oil of lemon twenty-five drops, so as to make a homogeneous powder. Form with a sufficient quantity of water a mass of the desired consistence, and divide into lozenges, each of which shall weigh, when dried, fifteen grains; each lozenge will then contain somewhat more than one-third of a grain of brown santonin. For infants under six months, the dose is one lozenge night and morning; from six months to a year, two lozenges; from one to two years, three lozenges; from two to four years, four, night and morning ; for those older, an extra lozenge for each year, to be given night and morning, and continued until the desired effects are produced, in every instance. M. Lecocq obtains santonin by taking one part of semen-contra of Aleppo reduced to coarse powder, and boiling it for a quarter of an hour with ten parts of water, after which a sufficient quantity of slaked lime is added to render the liquor slightly alkaline ; it is again boiled for ten minutes, then strained through a cloth, and the residue pressed. If it is not considered sufficiently exhausted, which may be ascertained by its leaving in the mouth the hot and pungent taste of semen-contra, it is boiled again with five quarts of water and a little slaked lime; it is then strained, and the residue submitted to pressure. The united liquors are evaporated until they do not weigh more than the semen-contra employ- ed ; they are then placed into a stone-ware pot, allowed to cool, and then treated with an excess of hydrochloric acid. A fatty and resinous mat- ter instantly separates, in thick flakes, which float, and santonin is pre- cipitated as an impalpable powder ; it is strained through a fine cloth ; the santonin passes with the liquor, and the resinous matters remain on the cloth. Th's substance, which contains only very little santonin is rejected. After a day's repose, the impure santonin is deposited at the bottom of the vessel. It is washed with distilled water, and purified by combining it anew with lime. For that purpose, it is put into a porcelain capsule, with about two quarts of distilled water, and boiled. A certain quantity (50 to 60 grammes) of pulverized quicklime is then added to it, and the combination is effected in a short time. The liquor is filtered and decolorized with animal charcoal, and then treated with hydro- chloric acid, which immediately precipitates the santonin; collect this on a paper filter, and wash it with distilled water until the washing water does not redden litmus paper, and dry in a stove secured from the light. Thus obtained, santonin occurs in pearly-white bracteae, of great 252 Materia Medica. brilliancy, and promptly becomes colored by light; it is therefore essen- tial to keep it in a black glass flask and well corked. It is important for the success of the above operation not to add an excess of lime in combining the impure santonin with this base, for the bibasic salt of santonin is very sparingly soluble in water; it is better to leave a slight excess of santonin; which will remain on the filter and which may be treated anew with lime.

Description. — Arum Triphyllum (Ariscema Triphylla) is variously called Wake Robin, Indian Turnip, Jack-in-the-pulpit, etc. It has a round, flattened, perennial root or cormus, the upper part of which is tunicated like the onion, and the lower and larger portion tuberous and fleshy, giving off numerous, long white radicles in a circle, from its upper edge; the under side is covered with a dark, loose, wrinkled epi- dermis. Early in the spring a large spathe grows up, which is ovate, acuminate, convoluted into a tube at the bottom, flattened and bent over at the top like a hood, varying in color internally, being green, dark- purple, black, or variegated, with pale-greenish stripes on a dark ground, and supported by an erect, round, green, purple, or variegated scape, invested at the base by the petioles and their acute sheaths. Within the spathe is a club-shaped spadix, shorter than the spathe, rounded at the end, green, purple, black, or variegated, contracted into a narrow neck at the base, where it is surrounded by the stamens or germs. In the fertile plants, it is invested with roundish crowded ovaries each tipped with a stigma; in the barren, its base is covered with conical, fleshy filaments, each bearing from two to four circular anthers. Plants which are perfectly monoecious, and which are the least common, have stamens below the ovaries. The upper portion of the spadix gradually decays, together with the spathe, while the ovaries are converted into a large compact bunch of shining, scarlet berries. The leaves are usually one or two in number, standing on long sheathing footstalks, ternate; the leaflets oval, mostly entire, acuminate, smooth, paler on the under-side, becoming glaucous as the plant grows, and the two lateral ones some- what rhomboidal. History.—This plant is common to North and South America, grow- ing in all moist and damp situations, and flowering from May to July. Asarum Europium. 253 The whole plant is acrid, but the root is the only part employed; it is about an inch or two in diameter, turnip-shaped, dark externally, and white, fleshy, and solid internally. When fresh, it is very acrid, causing when chewed, an intense burning and biting sensation in the mouth and fauces, which is persistent, and leaves a subsequent soreness; milk relieves this sensation, considerably modifying its intensity. It exerts no such influence upon the external skin except upon long and continued application. The acrid principle is highly volatile, is not taken up by water, alcohol, the acids, or oil, and is wholly dissipated by heat. It becomes inert by age, and should always be used in the recent state, or when but partially dried; if buried in sand, its activity may be pre- served for twelve or fifteen months. In addition to its acrid principle, it contains albumen, gum, sugar, starch, extractive lignin, and salts of potassa and lime. A very white, delicate and nutritive amylaceous substance can be prepared from it, resembling the finest arrowroot. It is too acrid for use when taken immediately from the ground. Properties and Uses.—Acrid, expectorant, and diaphoretic. Recom- mended in flatulence, asthma, pertussis, chronic catarrh, chronic rheu- matism, bronchitis, pains in the chest, aphthous sore-mouth, colic, low stage of typhus, and various affections connected with a cachectic state of the system. Externally it has been used in scrofulous tumors, tinea capitis, and other cutaneous diseases. Dose, of the powder, ten grains two or three times a day, gradually increased; it may be taken in syrup, honey, or gum arabic emulsion. Off. Prep.—Emplastrum Picis Compositum. ASARUM EUROPIUM.

Description.—This plant, sometimes called Hazelwort, or Wild Nard, has a creeping' root or rhizoma, entangled, with numerous, stout, branching fibers. The stems are very short, simple, round, herbaceous, pubescent, each bearing two dark-green, shining, reniform, obtuse, entire, somewhat downy leaves, which are opposite, two inches wide, and on long, downy footstalks; also one drooping flower, not an inch long, fleshy, of a dusky-purple color, and placed upon a short terminal peduncle. The calyx is campanulate, greenish at the base, divided into three pointed purplish segments, which are erect, and turned inward at their extremity. Corolla wanting. The filaments are twelve, and pro- longed beyond the anthers into a small hook. The style is surmounted 254 Materia Medica. by a six-parted reddish stigma. The fruit is a six-celled capsule, coria- ceous, and crowned with the persistent calyx. History.—This is a European plant, growing in woods and shady places. It flowers in May. The whole plant is usually employed, which, when recent, is quite acrid. The root is about the size of a goosequill, quadrangular, knotted, grayish, and occasionally with fibers at each joint. Its odor resembles pepper, and its taste is acrid; the leaves are bitter, acrid, nauseous, and slightly aromatic. The powder of the root is grayish, of the leaves yellowish-green. Their virtues are taken up by water or alcohol, but dissipated by boiling, and impaired by age. Analysis has found in the root, a liquid volatile oil, two con- crete volatile substances called Asarum Camphor or Asarone, and Asarite, a peculiar bitter principle called Asarin, tannin, extractive, resin, starch, gluten, albumen, lignin, citric acid, and various salts; in the leaves are asarin, tannin, extractive, chlorophylle, albumen, citric acid, and lignin. The volatile oil is yellow, of an acrid, burning taste, valerian-like odor, glutinous, and lighter than water; the asarin is soluble in alcohol, and is probably identical with cytisin. The roofe and leaves of this plant should always be carefully dried for preservation. Properties and Uses.—Emetic, cathartic, and errhine. Used princi- pally as an errhine in headache, chronic ophthalmia, rheumatic and paralytic affections of the face, mouth and throat. Internally, it is a stimulant in doses of ten or twelve grains; and emetic in half drachm or drachm doses. Said to be used in France by drunkards to produce vomiting. ASARUM CANADENSE. Wild Ginger. Nat. Ord.—Aristolochiaceae. Sex. Syst.—Dodecandria Monogynia. ROOT. Description. — Asarum Canadense, likewise called Indian Ginger, Coltsfoot, Canada Snakeroot, has a close resemblance to the A. Euro- paeum. The rhizoma is long, creeping, fleshy, jointed, yellowish, and furnished with radicles of a similar color. The stem is very short, dividing before it emerges from the ground into two long round hairy leafstalks, each of which bears a broad, reniform leaf, pubescent on both sides, light-green and shining above, veined and pale or bluish below. The flower is solitary, growing from the fork of the stem, upon a pen- dulous, hairy peduncle, being often concealed by the loose soil, or decayed vegetable matter around it. The calyx is very woolly, consisting of three broad concave, acuminate segments, of a brownish, dull-purple or greenish color on the inside, at top and bottom, depending on the ASCLEPIAS INCARNATA. 255 amount of light which the plant enjoys, and terminated by a lono-, spreading, inflected point, with reflexed sides. Corolla wanting Fila- ments twelve, unequal in length, inserted upon the ovary, and rise with a slender point above the anthers, which are attached to their sides just below the extremity. Ovary inferior, somewhat hexagonal; style coni- cal, striated, and parted at top into six recurved, radiating stigmas. Capsule six-celled, coriaceous, and crowned with the adhering calyx. History.—Wild Ginger is a native of the United States, growing in woods and shady places, and flowering from April to July. The whole plant has a grateful aromatic odor, and bitter, but agreeably aromatic taste. The root is the officinal part, and yields its active principles to alcohol, and partially to water. It is in long, contorted pieces, varying in thickness from a line to four or five lines in diameter, brownish and wrinkled externally, internally hard, brittle, and whitish. It contains a light-colored, pungent, and fragrant essential oil, a reddish, bitter resinous matter, starch, gum, fatty matter, chlorophylle, and salts of potassa, lime, and iron. Properties and Uses. — Aromatic stimulant, tonic, diaphoretic, and expectorant. Used in colic and other painful affections of the stomach and bowels where no inflammation exists, and in chronic pulmonary affections. Used also as an errhine. Dose of the powder, half a drachm; of the tincture half a drachm to two drachms. It may be advanta- geously added to tonic infusions and tinctures. Off. Prep.—Tinctura Lobeliae Coinposita. ASCLEPIAS INCARNATA. Swamp Milkweed. Nat. Ord.—Asclepiadaceae. Sex. Syst.—Pentandria Digynia. ROOT. Description.—This plant is known by various names, as Swamp Silk- weed, Flesh-colored Asclepias, Rose-colored Silkiveed, White Indian Hemp, etc. It has a smooth, erect stem, with two downy lines above and on the branches and peduncles, branching above, and about two or three feet high. The leaves are opposite, oblong-lanceolate, acute, or pointed, obtuse at the base, on short petioles, and slightly tomentose. The floioers are red or reddish-purple, sweet-scented, and disposed in numer- ous umbels which are crowded, erect, mostly terminal, and often in opposite pairs. Hoods of the crown entire, horns exsert, subulate. The leaves are four to seven inches long, and from one half an inch to an inch and a half wide ; umbels are from two to six, on a peduncle two 256 Materia Medica. inches long, and consist of from ten to twenty small flowers. There are several varieties of this plant, the A. Pulchra, which is more hairy, with broader and shorter petioled leaves ; the A. Glabra, which is almost glabrous, with two opposite longitudinal hairy lines on the stem, and leaves glabrous, with rough margins, midrib glandular below ; and the A. Alba which has white flowers. History.—This plant grows in damp and wet soils throughout the United States, and bears red flowers from June to August. It emits a milky juice on being wounded. The root is the officinal part; it varies in thickness from one to six lines, and is of a light-yellowish or brown- ish color. It imparts its properties to water. Properties and Uses.—Anthelmintic, for which purpose the powder may be used in doses of ten to twenty grains, three times a day ; or the decoction two to four ounces. Prof. Tully recommends it in catarrh, asthma, syphilis, rheumatism, and worms. Reputed to be emetic and cathartic. It is undoubtedly a valuable agent, and worthy further investigation. ASCLEPIAS SYRIACA. Common Silkweed. Nat. Ord.—Asclepiadaceae. Sex. Syst.—Pentandria Digynia. THE ROOT. Description.—Asclepias Syriaca, (the Asclepias Cornuti of Decaisne,) known as Milkweed in many parts of the country, has a large, stout, simple, somewhat branched stem, growing from two to five feet high. The leaves are opposite, oblong-lanceolate, petiolate, gradually acute, and tomentose beneath. The flowers are large, and sweet-scented, arranged on several umbels, which are axillary, subterminal, nodding, dense, glo- bose, each of twenty or more flowers. Calyx segments lanceolate. Corolla pale or greenish-purple, reflexed, leaving the corona, which is of nearly the same hue, quite conspicuous. But few of the flowers prove fertile, producing oblong, pointed pods or follicles covered with sharp prickles, which contain a mass of long, silky fibers with seeds attached, and which fibers have been used for beds, pillows, and in the place of fur in manufacturing hats. History.—Very common to the United States, growing in sandy fields, on roadsides, and on banks of streams. It bears whitish-purple flowers in July and August. The plant also gives out a milky juice when wounded. It contains water, wax-like fatty matter, caoutchouc, gum, sugar, with various salts. A crystalline resinous substance, allied to Asclepias Tuberosa. 257 lactucone, has been obtained from the juice of the A. Syriaca, to which the name of Asclepione has been given. To obtain it, the juice must be coagulated by heat, then filtered, to separate the liquid portion, and then digested with ether, which dissolves the asclepione, and yields it by evaporation. To purify it, treat the residue repeatedly with anhydrous ether, which leaves another substance undissolved. Asclepione is white, crystalline, tasteless, inodorous, fusible, insoluble in water or alcohol, soluble in ether, oil of turpentine, or concentrated acetic acid; potassa in a hot strong solution does not affect it. Properties and Uses.—Anodyne, emmenagogue, diuretic and altera- tive. Useful in amenorrhea, dropsy, retention of urine, dyspepsia, asthma, cough, dyspnoea, also, in scrofulous and rheumatic disorders. Both the root and inspissated milky juice possess anodyne properties. Dose of the powder, ten to twenty grains; of the decoction, two to four ounces ; of the tincture, ten to sixty minims. ASCLEPIAS TUBEROSA. Pleurisy Root. Nat. Ord.—Asclepiadaceaa. Sex. Syst.—Pentandria Digynia. the root. Description.—This plant has several names by which it is known in various parts of the country, as Bidterfly-weed, Windroot, Tuber-root, Asclepias, etc.; but it is most commonly described as Pleurisy-root. It has a perennial, large, fleshy, branching, white, and sometimes fusi- form-like root, from which numerous stems arise, growing from one to three feet high ; these are erect, or more or less procumbent, round, hairy, green or red, and growing in bunches from the root. The leaves are alternate, the lower ones pedunculated, the upper sessile, vary from linear to oblong-lanceolate, hairy, dark-green above, paler beneath, waved on the edge, and in the old plants sometimes revolute. The flowers are numerous, erect, of a beautifully r bright-orange color, and are disposed in terminal, rarely lateral, corymbose umbels, with an invo- lucre of numerous, linear, subulate bracts. The calyx is much smaller than the corolla, five-parted ; the segments subulate, reflexed, and con- cealed by the corolla. Corolla rotate, five-parted, the segments oblong and reflexed. The stamineal crown has five erect, cucullate leaves or cups, with an oblique mouth, having a small, incurved, acute appendage or horn, proceeding from the base of each, and meeting at the center of the flower. The mass of stamens is a tough, horny, somewhat pyra- midal substance, separable into five anthers; each two-celled, bordered by membranous, reflected edges contiguous to those of the next, and 17 258 Materia Medica. terminated by a membranous, reflected summit. Pollen masses ten, distinct, yellowish, transparent, flat and spathulate, ending in curved stalks, which unite them by pairs to a minute dark tubercle at top ; each pair is suspended in the cells of two adjoining anthers, so that if a needle be inserted between the membranous edges of two anthers and forced out at top, it carries with it a pair of the pollen masses. Carpels two, completely concealed beneath the stigma and anthers, ovate, with erect styles, terminated by a flat, pentagonal disk-like stigma. Follicles two, often one or both abortive, long, narrow, acuminated, green, with a red- dish tinge and downy. Seeds ovate, flat, margined, and terminated by long silken hairs. History.—This is an indigenous plant, growing in gravelly and sandy soils, but most abundant in the south, and flowering in July and August. Unlike the other species of Asclepias, this plant does not emit a milky juice when wounded. The root is the officinal part, which when fresh has a subacrid, nauseous taste, but when dried it is easily pulverized, and has a bitterish but not disagreeable taste. Boiling water or alcohol extracts its virtues. Properties and Uses.—Diaphoretic and expectorant, without stimu- lating ; likewise said to be carminative, diuretic, tonic, and antispasmo- dic. Principally used in decoction or infusion in pleurisy, pneumonia, catarrh, febrile diseases, acute rheumatism, and dysentery; in which it is administered warm to promote diaphoresis, without increasing the temperature of the body. In flatulency and indigestion, it is efficient, and when combined with the Dioscorea Villosa, it is very beneficial in all cases of flatus in adults and children. A number of cases of prolapsus uteri have been cured under the use of one ounce of pleurisy-root mixed with half an ounce of the root of Aletris Farinosa, and given in drachm doses, three times a day. In uterine difficulties this plant deserves further investigation. It is, undoubtedly, one of our most useful agents. Dose of the powder, one scruple to one drachm, three or four times a day; of the decoction or infusion, a teacupful, every hour or two, until diaphoresis is produced. Two concentrated preparations are obtained from this article, termed Asclepidin and Ascletine. The former was first manufactured by Mr. W. S. Merrell, the latter by some chemists in N. York; of the particular method of preparing the latter, we have been unable to get any account The asclepidin is a dark, semiliquid mass, and is prepared by evapora- tion or distillation of the saturated tincture in water, similar to the plan pursued for obtaining cimicifugin. It may be used for all purposes to which the crude article is applied in doses of from one to five grains, three or four times a day, or as may be indicated. A pill composed of equal parts of asclepidin and dioscorein, will be found very beneficial in flatulency, borborygmi, and where persons are Asparagus Officinalis. 289 subject to flatulent and bilious colic. In some cases, especially of long standing, the addition of pulverized African ginger will much improve its efficacy. Ascletine is said to be the active principle of the plant; it is a beauti- ful, white powder, with but little taste or odor, soluble in water, but insoluble in alcohol. It is recommended in the same diseases in which the root is employed, to fulfill similar indications, in doses of from one to three grains, three or four times a day. Off.

Description.—Asparagus officinalis is a perennial plant, with an erect, herbaceous, unarmed, terete, very branching stem, from two to four feet high. The leaves are setaceous, flexible, fasciculate, filiform, of a pale pea-green color and from half an inch to one and a half inches long; flowers axillary, solitary, or in pairs. Berries globose, red, three-celled. Cells two-seeded. History.—This plant is a native of Europe and is extensively cultivated there, as well as in the United States, as an article of diet. The root is inodorous, and has a weak sweetish taste ; when dried it is inert. The young shoots or turiones, which are much used as food, have a disagree- able taste, which is removed by boiling with water ; their juice contains a crystallizable principle called Asparagin or Asparamide. Properties and Uses. — Diuretic. A syrup or an extract prepared from the young shoots, in doses of one or two fluidounces of the former, or from half a drachm to a drachm of the latter, is said to greatly increase the quantity of urine, and is reputed very beneficial in repres- sing an undue excitement of the circulatory system, and recommended for this purpose in hypertrophy of the heart, and other diseases of that organ, attended with excessive action, and without phlogosis of the Btomach. * 260 Materia Medica. ASPIDIUM FILIX MAS. Male Fern. Nat. Ord.—Filices or Filicaceae.—Polypodiaceae. Sex. Syst.—Cryptogamia Filices. RHIZOMA. Description.—Male fern has a large, perennial, horizontal, scaly root or rhizoma, from which numerous fronds or leaves arise, forming tufts from a foot to four feet in hight. The fronds are erect, disposed in a circle, oval, lanceolate, acute, pinnate, bright-green, and leafy nearly to the bottom ; their stalks and midribs having tough, brown, transparent scales throughout; divisions alternate, taper-pointed, pinnate; the pinna or leaflets numerous, crowded, sessile, for the most part distinct, occa- sionally somewhat combined at the base, oblong, obtuse, crenate through- out, the lateral notches broadest and most shallow, the terminal ones more crowded and acute, without any terminal bristles; both sides smooth, and,destitute of glandular globules, but a depression on the upper one over trie insertion of each sorus. Sori circular, tawny, ranged in simple, close, short rows, near the partial midrib, and scarcely occupying more than the lower half of each leaflet. Indusium circular, durable, crenate, tumid, with a cleft terminating in the central depression. Theca? numerous, shining-brown, prominent all round for a little beyond the indusium. History.—Found growing in all parts of Europe, and indigenous, growing in shady pine forests, from New York to Virginia. The root or rhizoma is the officinal part; the best are about six inches long, and an inch broad ; externally it is of a brown color, internally yellowish or reddish-white, with a peculiar, but not very strong odor, and a sweetish, bitter, nauseous and astringent taste. It should be collected between the end of May and middle of September ; cleansed, without being washed; then dried quickly in the shade and open air without heat, those parts selected which are greenish, internally, immediately pulver- ized, and then kept in well-closed bottles. The powder is of a pale greenish-yellow color, and has a peculiar, earthy, disagreeable odor, and a nauseously sweet taste, followed by some bitterness and astringency. It loses its virtues in two years. An ethereal oil is obtained by evapo- rating or distilling off the ether from an ethereal tincture. It is a thick, dark, liquid, with the odor and taste of the root, though somewhat acrid, and contains volatile oil, resin, coloring matter, etc. The purer the ether used, the less resin is taken up. Male fern root contains a volatile oil, a fixed oil, resin, gallic and acetic acids, uncrys- tallizable sugar, tannin, starch, a gelatinous matter insoluble in water and alcohol, lignin, and various earthy and saline matters. Astragalus Verus. 261 Properties and Uses.—Anthelmintic. Used solely for the removal of worms, especially the tapeworm. It is said to be more effectual in removing the tapeworm of Switzerland (Boihriocephalus lotus) than the Taenia solium, the most frequent variety in France and England. The best mode of administration is the ethereal oil or extract, of which eighteen grains, or from twelve to twenty-four drops may be given in the form of pill or emulsion, at night, and again in the morning; two hours after the administration of the last dose, a purgative dose of castor oil is to be taken, and the worm is discharged dead, without any severe or unpleasant symptoms. Dose of the powder, one to four drachms; of the ethereal tincture of the buds, eight to thirty drops, and which is made by digesting one part of the buds, in eight parts of ether. ASTRAGALUS VERUS. Tragacanth. Nat. Ord.—Fabacea?. Sex. Syst. — Diadelphia Decandria. THE CONCRETE JUICE. Description. — This is a small shrub about two or three feet in hight, with a stem about an inch in thickness, and numerous, very closely crowded branches, covered with imbricated scales, and spines which are the remains of former petioles. The leaves are a little more than half an inch long, and consist of from sixteen to eighteen opposite, villous, stiff, pointed, linear, hispid leaflets, with a midrib terminating in a sharp yellowish point; stipules at first downy, afterward smooth. The flowers are small, yellow, axillary, in clusters of from two to five, sessile, papilionaceous, and furnished with cottony bracts. Calyx tomentose, obscurely five-toothed. History. — Tragacantha or Tragacanth is obtained from several species of plants, belonging to the genus Astragalus. The A. Traga- cantha of Linnaeus, now the A. Massiliensis of Lamarck, a tree growing in southern Europe and northern Africa, and which yields no gum, was formerly referred to as affording the drug, but this is now known to be incorrect. The greater portion of the species from which tragacanth is obtained, are natives of Asia, having rigidly persistent petioles, forming- spines. Most of the spinous species, furnish the peculiar exudation, which is known in commerce, as Gum Tragacanth, especially those in- habiting warm regions, but Botanists have not positively determined as to the particular plants. The A. Verus, a low and very hispid shrub, is stated by Olivier to afford the largest proportion of the gum sent to Europe. It is found growing naturally in Persia, Armenia and Asia Minor. The gum exudes from the stem naturally, or after incisions, 262 Materia Medica. hardening as it exudes ; and is gathered from July till September. It is forwarded to India through Bagdad and Bassoro, then to Russia, and from thence to Aleppo. The other species which are admitted to fur- nish the gum, are A. Gummifer, a native of Syria and Koordistan, which is said to yield the white or best variety; A. Crelicus, growing in Crete, and A. Aristatus, a native of Greece and the south of Europe, and reputed to afford some of the tragacanth imported from Smyrna and Marseilles. Professor Lindley has likewise described another species, the A. Strobiliferus, growing in Koordistan, and furnishing the dark- colored, or inferior gum, which is mingled with the commercial article; but this requires confirmation. The plants which yield tragacanth, resemble each other so closely, that much confusion has existed among Botanists in distinguishing them. Tragacanth presents the appearance of very thin, pale-grayish, or grayish-yellow, almost parchment-like plates or scales, marked by spiral or circular ridges. It is semitransparent, or translucent, resembling horn in appearance, hard, more or less fragile, but difficult of pulveriza- tion, unless exposed to a freezing temperature, or thoroughly dried, and powdered in a heated mortar, tasteless and inodorous. Its powder is very fine and white. Sometimes pieces of a slightly reddish color are met with, of a roundish or irregularly oblong shape. The specific gravity of tragacanth is 1.384. Cold or boiling water converts it into mucilage; introduced into cold water, it absorbs a portion of that fluid, swells very much, and forms a paste without being dissolved. By boiling, its solu- tion is nearly completed. The mucilage is changed to a blue color by the addition of iodine, owing to the presence of a small proportion of starch. Tragacanth is insoluble in alcohol, and is composed of a sub- stance soluble in water, and a substance not soluble, but which swells when placed in water. The soluble portion resembles gum arabic, but differs from it by not yielding any precipitate with silicate of potassa or sesquichloride of iron ; the insoluble portion is called Tragacanthin, con- stitutes 43 per cent, of the drugs, and is supposed to be identical with bassorin, with a small quantity of insoluble starch. The composition of tragacanth is not satisfactorily settled by chemists ; M. Guerin considers it to be a compound of 53.3 parts of arabin or soluble gum, 33.1 of bassorin and insoluble starch, 11.1 of water, and when burned 2.5 of ashes. Properties and Uses.—Tragacanth is nutritive and demulcent; seldom used except for the suspension of heavy, insoluble powders, to impart consistence to troches and lozenges, and to form paste for the druggists, with which to label their prescriptions. Assafcetida. 263 ASSAFQ3TIDA. Assafcetida. Nat. Ord.—Apiacese, or Umbellifera. Sex. Syst.—Pentandria Digynia. CONCRETE JUICE OF THE ROOT OF FERULA ASSAFCETIDA. Description.—Ferula Assafcetida, Linnaeus, or Narthex Assafcetida, Falconer, is described by Kcempfer, who wrote from actual observation. It has a perennial, fleshy, tapering root, with a coarse hairy, or fibrous summit, about the size of a man's leg when full-grown, either simple like a parsnep, or with one or more forks ; externally it is blackish, inter- nally white, and abounding in a very fetid, opake, milky juice. The leaves are radical, six or seven in number, nearly two feet long, shining, coriaceous, deep-green, pinnated, with pinnatifid segments whose lobes are oblong and obtuse; petiole terete, amplexicaul, channeled only at the base. The leaves grow vigorously through the winter, and wither at the termination of spring. From the midst of the leaves, rises a luxu- riant, herbaceous stem, from six to ten feet high, two inches in diameter at the base, solid, simple, erect, round, smooth, striated, the spongy medulla traversed by bundles of tough, fibrous vessels, the surface clothed with the remains of persistent leafless petioles, and terminating in large plano-convex umbels with numerous radii. The flowers are pale-yellow ; the fruit is flat, oval, thin, reddish-brown, slightly hairy or rough. The plant varies in its appearance, according to its situation and soil. History.—This plant is a native of Persia. The gum-resin is prepared from incisions into the upper portion of the root, or by taking successive slices from it; plants under four years are not made use of, as they yield but little, if any, of the juice. At the time the leaves begin to fade, the root-leaves and stem are twisted off close to the root, and the soil is removed from its crown. About forty days afterward, a thin slice is cut off transversely from its summit, and a milky juice of a fetid, alliaceous odor gradually exudes. In about two days, or when this exudation has become hardened, it is scraped off, and another thin slice removed as before, from which juice again flows, and this process is repeated until no more juice can be obtained ; while this collection is going on, the root is constantly protected from the solar rays. The concrete juice from several plants, are then put together, further hardened, and disposed of for home use or foreign exportation. The assafcetida in this country is either from India, or Great Britain, in mats, cases or casks, of from eighty pounds to several hundreds each. This gum-resin as met with in the shops is in masses of different sizes, rather soft, varying in color, becoming reddish, and finally a dull yellow- ish-brown on exposure to the atmosphere ; on being broken it presents 264 Materia Medica. a shining, whitish surface, and changes color as it becomes exposed. The masses have an irregular, amygdaloid appearance, being composed of whitish tears agglutinated together. Sometimes the tears are to be had separate; they are oval, irregular, of the size of a pea or larger, brownish externally, white internally, and of weaker odor than that of the masses. The better the article is in the masses, the greater the quantity of tears, with but a small portion of the dark, soft, agglutinat- ing material in which they are imbedded. Assafcetida has a fetid, tena- cious and alliaceous odor, and a strong, peculiar, persistent, bitterish, and rather acrid taste. Age hardens it and renders it brittle, beside diminishing its taste and odor. It can only be pulverized at a low tem- perature, as in frosty weather; in warm weather it softens under the pestle. Moderate heat softens it so far that it may be squeezed through a coarse cloth, and freed from impurities of a mechanical nature; a stronger heat causes it to froth up, and at a red heat it burns with clear, lively flame. Its specific gravity is 1.327. Rubbed with cold or warm water, the gum is dissolved, forming a smooth white or pink- colored persistent emulsion, in which the resin and volatile oil are sus- pended. With rectified alcohol it forms a clear tincture, which is its best menstruum. Spirit dissolves the resin and oil, but is too feeble a solvent. Sulphuric ether dissolves the volatile oil and a portion of resin ; solution of caustic potassa dissolves it almost entirely, forming an emul- sion when the alkali is neutralized; and solution of ammonia dissolves the gum and oil, with part of the resin. It readily unites with other resins, gum-resins, and wax; and is best preserved in bladders kept in tin boxes. Assafoetida contains volatile oil, resin soluble in ether, a tasteless resin insoluble in ether, gum, bassorin, sulphate of lime, carbonate of lime, oxide of iron and alumina, malate of lime, etc. The volatile oil may be procured by distillation with water or alcohol, at first it is pale-green, but becomes yellowish-brown by age, is lighter than water, of a power- fully offensive odor, and a taste peculiar to the gum-resin ; it contains sulphur. This and the bitter resin are the active principles. Properties and Uses.—Stimulant, antispasmodic, expectorant, emmen- agogue, and feebly laxative. Improper in inflammatory conditions of the system. Used in hysteria, hypochondria, convulsions, spasmodic nervous diseases of females, spasm of the stomach and bowels, various irregular nervous disorders which accompany debility of the nervous system, and, in combination with morphia and quinia, in sick or nerv- ous headache. With podophyllin and cunicifugin it is beneficial in chorea. Also useful in pertussis, asthma, infantile coughs and catarrhs, croup, measles, etc., whenever there is a want of nervous energy, or disposition to sink. Likewise efficient in amenorrhea and dysmenorrhea, and as an injection in tympanitic abdomen, lumbricus and ascarides. Dose, in Aster Puniceus. 265 powder or pill, from five to ten grains ; of the tincture, from half a drachm to two drachms. Off.

THE ROOT. Description.—The root of this plant is perennial and fibrous ; the stem is hispid, paniculate above, furrowed, generally red, or at least on the south side, stout and tall, growing from three to six feet in hight. The leaves are oblong-lanceolate, amplexicaul, and more or less auriculate at base, sparingly serrate in the middle with appressed teeth, rough above, nearly smooth underneath, pointed ; lower leaves with remote serratures, rough edged, and rough on the upper surface, all acuminate and nar- rowed at the base. Involucre loose, longer than the disk ; the scales linear-lanceolate, long, revolute, nearly equal, and in two rows. Flowers large, showy, and of a pale purple or lilac-blue color. Rays from fifty to eighty, long and narrow. History.—This plant is found growing in various parts of the United States, in swamps, ditches, along the borders of small streams, and sometimes in dry soils. It flowers from July to October. The radicles or fibers of the root, are the parts used ; they are about the size of a pipestem, having a pungent, aromatic odor and taste, with some bitter- ness and astringency. Water or alcohol extracts their active properties. This plant is variously known by the names of Cocash, Meadow Scabisk, Squaw-weed, etc. Properties and Uses.—Stimulant and diaphoretic. The warm infusion may be used freely in colds, rheumatism, nervous debility, headache, pains in the stomach, dizziness, and menstrual irregularities. This, together with the A. Cordifolius are probably equivalents of valerian. The Aster ^Estivus, named Rheumatic-weed, also Sampson Snakeroot, Star-flower, etc., resembles the above plant, having lanceolate, sub-clasp- ing leaves, tapering to the apex; margin rough ; stem branching from its base, erect, hispid ; branchlets pilose; involucre scaly ; scales lax, linear, acute, equal. Flowers middle sized, and blue. It is found more abundantly west of the Alleghany mountains, and is recommended as an antispasmodic and alterative. Principally used in the cure of rheu- matism in the form of infusion or tincture ; recommended, however, in hysteria, chorea, epilepsy, spasms, irregular menstruation, etc., internally; 266 Materia Medica. and used both externally and internally in many cutaneous diseases, the eruption occasioned by the poison rhus, and in the bites of venomous snakes. Dose of the infusion, one to four ounces ; of a saturated tinc- ture half a drachm to two drachms. This plant deserves further inves- tigation. ATROPA BELLADONNA. Belladonna. Nat. Ord.—Solanaceas. Sex. Syst.—Pentandria Monogynia. LEAVES. Description. — Atropa Belladonna, also known as Deadly Nightshade, Dwale, Black Cherry, etc., is a herbaceous, perennial plant, with a thick, branched, fleshy, creeping root, from which rise several erect, cylindri- cal, herbaceous, annual, hirsute, purplish stems, to the hight of three or four feet. The branches are dichotomous, with ovate, entire, somewhat soft leaves, acuminate at both ends, of a dull-green color, mostly in pairs of unequal size, and on short petioles. The flowers are imperfectly axillary, solitary, stalked, and drooping. The calyx is green, persistent, and divided into five ovate segments. The corolla is monopetalous, cam- panulate, with the limb divided into five lobes, dark dull purple in the border, paler downward. Stamens five, shorter than the corolla, bear- ing cordate, four-lobed anthers. Ovary spheroidal, with a nectariferous gland beneath, and supporting a long, simple style, with a two-lobed stigma. The fruit is a round, two-celled berry, bearing some resem- blance to a cherry, with a transverse furrow on each side, shining, smooth, at first green, then red, and finally of a deep purple color, and containing numerous reniform seeds, imbedded in a soft pulp, with a sweetish, violet-colored juice. When bruised, the whole plant exhales a fetid odor. History.—This plant is a native of Europe, growing in shady places, flowering in June and July, and ripening its fruit in September; all parts of it are active. The leaves are the officinal part, and should be col- lected in June or July; when dry, they are of a brownish-green, or grayish-green color, scarcely any odor, and a faint, sweetish, slightly nauseous taste, and yield their properties readily to alcohol or water. The root is long, round, varying in thickness from one to several inches, fibrous, branched, reddish-brown externally, whitish internally, scarcely any odor, and a slightly sweetish taste. It should be collected early in the spring, or in the autumn, from plants at least three years old; water or alcohol is its menstruum. The extract is more commonly used than any other form. Belladonna contains atropia with excess of malic acid, pseudotoxin, phytocolla, chlorophylle, gum, starch, etc. Atropia. 267 Properties and Uses.—An energetic narcotic poison. When taken in large doses it exerts an influence over the cerebro-spinal system, as manifested by dilation of the pupils, dimness or loss of vision, vertigo, partial deafness, confusion of ideas, constriction in the throat, difficulty of swallowing and articulating, thirst, nausea, and often the appearance of a red eruption; if the dose be excessive, all these symptoms will be greatly aggravated, with delirium, excessive laughter, violent gestures, and finally coma; when it causes death, convulsions often precede this result. Medicinally, it is anodyne, antispasmodic, and calmative, with some diaphoretic and diuretic properties. It is exceedingly valuable and useful in convulsions, spasms, epilepsy, puerperal convulsions, neuralgia, hooping-cough, chorea, mania, paralysis, amaurosis, rheumatism, gout, dysmenorrhea, obstinate intermittents, rigidity of os uteri, and all dis- eases in which the nervous system is involved. It is much in use as a prophylactic in scarlatina. Used externally, for dilating the pupil of the eye in various operations on that organ, to remove spasmodic stricture of urethra, neck of the bladder, and sphincter ani. Recommended, also, in strangulated hernia, asthma, and paraphimosis. The following has been recommended in neuralgia of the uterus: Mix together one grain and a half of alcoholic extract of belladonna, and three-fourths of a grain of opium. Place the two extracts in the center of a little pledget of carded cotton, and fold it up so as to inclose the extract; tie it up with a very strong thread, and leave a double thread eight inches long attached to it. The plug is to be introduced into the vagina by the physician or patient, and placed upon the neck of the uterus, where it is to be retained from twelve to twenty-four hours. In very painful men- struation accompanied by leucorrhea, from eight to fifteen grains of tannic acid, or geraniin may be added to the tampon. Dose of the powdered leaves, one to two grains, once or twice a day, and gradually increased till the peculiar effects of the medicine are produced; of the extract one-fourth of a grain to two grains. The remedies in cases of poisoning by it, are the stomach-pump, emetics and purgatives, cold to the head, and in the comatose stage, ammonia internally, with external stimulants. * Off.

BELLADONNA. Preparation.—The following is the process employed by Mein. The roots of plants two or three years old were selected. Of these, reduced 268 Materia Medica. to an extremely fine powder, 24 parts were digested, for several days, with 60 parts of alcohol of 86 or 90 per cent. The liquid having been separated by strong expression, the residue was treated anew with an equal quantity of alcohol; and the tinctures, poured together and filtered, were mixed with one part of hydrate of lime, and frequently shaken for twenty-four hours. The copious precipitate which now formed was separated by filtering; and diluted sulphuric acid was added drop by drop to the filtered liquor, till slightly in excess. The sulphate of lime having been separated by a new filtration, the alcoholic liquid was distilled to one-half, then mixed with six or eight parts of pure water, and evaporated with a gentle heat till the whole of the alcohol was driven off. The residual liquid was filtered, cautiously evaporated to one-third, and allowed to cool. A concentrated aqueous solution of car- bonate of potassa was then gradually added, so long as the liquid con- tinued to be rendered turbid; and the mixture was afterward suffered to rest some hours. A yellowish resinous substance which opposes the crystallization of the atropia was thus precipitated. From this the liquid was carefully decanted, and a small additional quantity of the solution of the carbonate was dropped into it, till it no longer became turbid. A gelatinous mass now gradually formed, which, at the end of twelve or twenty-four hours, was agitated in order to separate the mother- waters, then thrown upon a filter, and dried by folds of unsized paper. The substance thus obtained, which was atropia in an impure state, was dissolved in five times its weight of alcohol; and the solution, having been filtered, was mixed with six or eight times its bulk of water. The liquor soon became milky, or was rendered so by evaporating the excess of alcohol, and, in the course of twelve or twenty-four hours, deposited the atropia in the form of light yellow crystals, which were rendered entirely pure and colorless by washing with a few drops of water, dry- ing on blotting paper, and again treating with alcohol as before. From twelve ounces of the root, Mein obtained by this process twenty grains of the pure alkali.—Jour, de Pharm. xx, 87. . History.—Thus prepared, atropia crystallizes in white silky prisms, is inodorous, and of a bitter taste; dissolves in ether or absolute alcohol, and slightly in water; it melts above 212°, and forms soluble salts with sulphuric, nitric, muriatic, and acetic acids. At an ordinary tempera- ture, water dissolves about ^^h, but aided by heat a much larger portion is taken up; the solution has a bitter, disagreeable taste. Dr. A. von Planta found atropia prepared by Merck to possess the following properties: It dissolved in 299 parts of water at the ordinary tempera- ture; alcohol dissolved it in almost every proportion, ether less readily. Its solubility in all these fluids was increased by heat. At 194° F. it fused to a clear transparent mass,, which became brittle on cooling; on the reapplication of heat, and again allowing it to cool, it was converted Avenge Farina. 269 into stellate groups of crystals. At 284° F. the greater portion is destroyed. Heated upon platinum foil, it melts, puffs up, gives off white fumes, and burns with a bright flame, leaving a shining black cinder, which finally disappears entirely. It has a strong alkaline reaction, and combines with acids forming uncrystallizable salts, soluble in water and alcohol, but sparingly so in ether. Its formula is C34 H25 N Oe = 289. Properties and Uses.—Same as Belladonna. Internally from one-twen- tieth to one-tenth of a grain may be given; and for external use it is preferred on account of its quicker action, more uniform strength, and greater cleanliness. One grain dissolved in four fluidrachms of distilled water by means of a few drops of acetic acid, will, on the application of one drop of this solution to the inner surface of the lower lid, cause dilatation of the pupil in fifteen or twenty minutes. In neuralgia, one grain may be mixed with a drachm of lard, and rubbed on the affected part. Dr. Lusanna has used it successfully in this affection by the endermic and iatraleptic method. The skin being previously removed by a blister, or, what is still better, because more speedy, the ammonia- cal pomade of Goudret, when the atropia is dissolved in a small quantity of alcohol, then mixed with simple ointment and applied to the denuded surface. In this way, a half grain to a grain may be employed in the twenty-four or forty-eight hours. Iatraleptically, he uses the following ointment in the form of frictions over the part affected every two or three hours, consuming a portion the size of a pea each time : R-. Atro- pia, 5 centigrammes, Alcohol at 36, q. s. Dissolve. Add axungia, 12 grammes. AVENGE FARINA. Oatmeal. Nat. Ord.—Graminaceae. Sex. Syst.—Triandria Digynia. seeds of avena sativa, ground. Description.—Avena Sativa, or the common oat, is too well known to require a minute description; it has a smooth stem, from two to four feet high, with linear lanceolate, veined, rough leaves, with loose, striate sheaths; stipules lacerate; panicle equal, loose; spikelets pedunculate, pendulous, two-flowered, both flowers perfect, the lower one mostly awned ; paleae somewhat cartilaginous, closely embracing the caryopsis ; root fibrous, annual. History.—Oats were known to the ancient Greeks and are at present cultivated in all civilized countries, principally as food for horses. They have been naturalized in Sicily, and have been found in the island of 270 Materia Medica. Juan Fernandez. Their native country is unknown. In the north of England, Scotland, and Ireland, in some parts of France, and other countries, oats form a large portion of the nutriment of the inhabitants. The meal, which is prepared by grinding the seeds, is made into a gruel, and is very nutritious and digestible, beside being somewhat laxative; it forms an excellent diet for the sick in many cases. The British colleges direct groats, which are the seeds deprived of their husks; and these, when ground into fine meal or flour, are prepared groats. Oats contain, according to the analysis of Vogel, 66 per cent, of meal, and 34 per cent, of husk; the dried meal consists of starch 59, saccharo- mucilaginous extract 10.75, albumen 4.3, oleaginous matter 2, ligneous fiber and moisture 24. Other analyses have been made, which vary from the above in quantity and elements, showing oats to consist of a large proportion of starch, some sugar, gum, oil, albumen, gluten, a nitrogenous body, epidermis, alkaline salts, etc. Oatmeal is inodorous, slightly bitter, insoluble in alcohol, ether, and the oils; but alcohol and ether remove an oleo-resinous matter from it; it yields its nutritive properties freely to boiling water. Properties and Uses.—Nutritive and demulcent. Good in habitual constipation, but not in dyspepsia, accompanied with acidity of stomach. In the form of gruel, either salted or seasoned with sugar, honey, or the pulp of fruit, it is an agreeable nutritive during convalescence from acute diseases, in the puerperal woman, and in some chronic diseases. Oatmeal made into a cake with water, baked and browned like coffee, then pulverized and made into a coffee, or infusion, forms a drink which will allay nausea and check vomiting, in a majority of cases, when all other means fail, and used thus is very useful in diarrhea, dysentery, cholera-morbus, and irritable conditions of the stomach. Oatmeal gruel may be prepared by boiling an ounce of the meal with three pints of water to a quart, straining the decoction, allowing it to stand till it cools, and then pouring off the clear liquor from the sediment. Sugar, raisins, or lemon-juice are frequently added to improve its flavor. BALSAMODENDRON MYRRHA. Myrrh. Nat. Ord.—Amyridaceae, or Burseraceae. Sex. Syst.—Octandria Monogynia. CONCRETE JUICE OR GUMMY RESINOUS EXUDATION. Description.—The Balsamodendron Myrrha, is a small shrubby tree, covered with a pale gray or whitish gray bark, and with squarrose and spinose branches. The leaves are ternate, on short petioles, and consist Balsamodendron Myrrha. 271 of obovate, obtuse, smooth leaflets, somewhat denticulate at the apex. The flowers are unknown. The fruit is oval, lanceolate, pointed, smooth, longitudinally furrowed, of a brown color, a little larger than a pea, sup- ported on a very short peduncle, and surrounded at its base by the per- sistent calyx. History.—The myrrh tree grows in Arabia, and in the neighborhood of Abyssinia and the Red sea. The juice exudes spontaneously and concretes upon the bark, which when collected is the medicinal gum myrrh. The best kind of myrrh is in irregular pieces, somewhat resem- bling tears, often tuberculated, varying in size from a pea to a large walnut, or even larger, of a bright reddish-brown color becoming clearer red when breathed upon. Myrrh is brittle and pulverizable, and has a peculiar, agreeable, balsamic odor, and a bitter, aromatic, not unpleasant taste. When heated it softens, then froths up, and at length inflames and burns with difficulty. Its active constituents are oil and resin, and its proper solvent is rectified spirit. It is only partially soluble in water, proof spirit, and ether; water dissolves its arabin, and the mucilage retains the oil and part of the resin in the state of emulsion ; proof spirit dissolves some of the resin. Water added to its alcoholic tincture renders it opake, but without any precipitation. Alkaline solutions dissolve the gum resin. Myrrh consists of volatile oil 2.6, bitter resin 23, soluble gum 46, insoluble gum 12. Ruickholdt has obtained in 100 parts, volatile oil 2.183, resin 44.760, arabin 40.818, water 1.475, and various salts, etc., 3.650. He calls the resin myrrhin ; it is neutral, but by being kept in a state of fusion for a short time acquires acid properties, which state he proposes to term Myrrhic Acid. Myrrh added to nitric acid, produces a transparent, dirty-yellowish liquid; false myrrh produces a bright yellow liquid, and bdellium is not dissolved by it, but becomes whitish and opake. M. Righini states that if myrrh in powder, be rubbed for ten or fifteen minutes with an equal weight of muriate of ammonia, and fifteen times its weight of water gradually added, it may be considered pure, if it dissolves quickly and wholly. Properties and Uses.—Stimulant tonic, antiseptic, expectorant, em- menagogue, and by some considered anthelmintic. Used in debilitated states of the system, in chronic catarrh, phthisis, humoral asthma, other pectoral affections in which mucus secretion though abundant is not easily expectorated, chlorosis, amenorrhea, etc. Also reputed useful in chronic gonorrhea, gleet, and other excessive chronic mucous discharges. As a local application it is useful in spongy gums, aphthous sore mouth of children, indolent and gangrenous ulcers. It is sometimes combined with hydrastis and capsicum, in aphthae, and with tincture of castor as an emmenagogue. Dose of the powder, ten to thirty grains ; of the tincture, one to two drachms. 272 Materia Medica. Off.

BAPTISIA TINCTORIA. Wild Indigo. Nat. Ord.—Fabaceaa. Sex. Syst.—Decandria Monogynia. BARK OF THE ROOT AND LEAVES. Description.—Baptisia Tinctoria, also known as Horse-fly weed, Rattle- bush, etc., has a large and woody perennial root, very irregular, blackish externally, and yellowish within, with numerous, lighter-colored radicles. The stem is round, yellowish-green, smooth, marked with black dots, much branched, and growing from two to three feet high; the branches are slender, and of a yellowish color. The leaves are small, alternate, and formed of three sessile, obovate, smooth, bluish-green leaflets, with minute, evanescent stipules. Racemes loose, terminal, few-flowered. Flowers yellow, in small loose spikes at the ends of the branches, six, twelve or more in each raceme. Calyx campanulate, bilabiate, upper lip entire or emarginate, lower trifid. Stamina included, deciduous. Ovary stipitate, bearing a minute stigma. Legume bluish-black, about as large as a pea, on a long stipe, inflated, oblong, with a row of small subreniform seeds. History.—This is a small shrub, found in most parts of the United States in dry situations, though occasionally it is to be met with in low, marshy ground. It flowers in July and August, having bright yellow flowers, in small loose clusters at the end of the branches. The fruit is an oblong pod, of a bluish-black color. It contains indigo, tannin, an acid, and baptism. When the whole plant, or any portion of it is dried, it becomes black, and affords a blue dye, inferior to indigo. In some parts of the country the young shoots are used as a substitute for aspa- ragus, to which they bear some resemblance, and they occasionally cause drastic purgation, especially if used after they assume a green color. Alcohol, or water will take up its active properties. Both the root and leaves are medicinal, and deserve further investigation. The root is inodorous, and of a nauseous, somewhat acrid taste ; its virtues appear to reside chiefly in the bark. Properties and Uses. — Purgative, emetic, stimulant, astringent and antiseptic. Principally used on account of its antiseptic virtues. A decoction of the bark of the root is an excellent application as a wash or gargle to all species of ulcers, as malignant ulcerous sore mouth and Baptisia Tinctoria. 273 throat, mercurial sore mouth, scrofulous, or syphilitic ophthalmia, ery- sipelatous ulcers, gangrenous ulcers, sore nipples, etc. ; or it may be made into an ointment for external application. As a poultice or fomen- tation it is highly useful in all ulcers, tumors, or inflammations tending to gangrene. In fetid leucorrhea, fetid discharges from the ears, etc., the decoction will be found efficient, if injected into the parts with a suitable syringe. The leaves applied in fomentations, have discussed tumors and swelling of the female breast, resembling scirrhus. Internally, it may be used in the form of decoction or syrup, in scar- latina, typhus, and all cases where there is a tendency to putrescency. It acts powerfully on the glandular and nervous systems, increasing all the glandular secretions, and arousing the liver especially to a normal action ; and is very efficient in the atonic varieties of acute rheumatism and pneumonia. I make much use of the dried alcoholic extract of the root-bark in the low stage of typhoid, and typhoid conditions generally in conjunction with leptandrin ; and have used it extensively for the last ten years, and with very excellent effect in all diseases of a tuberculous character. I take pleasure in introducing to the profession, the active principle of this plant. Baptisin, prepared similarly to Aletrin, or it may be pre- cipitated by an acid, or by acetate of lead from the saturated tincture : I have found it to exert a powerful influence on the glandular system in doses of from one-fourth to one half a grain ; if given in large doses it produces a very disagreeable prostration of the whole system. It is also an excellent application to gangrenous and erysipelatous ulcerations, malignant and fetid ulcerations of the cervix uteri. Combined with lep- tandrin, podophyllin, quinia, or cimicifugin, in diseases where these agents are indicated, it will be found valuable in typhus and typhoid fevers, and all diseases of a typhoid character, when administered inter- nally. Baptisin is of a yellowish-brown color, a strong odor, similar to that of the powdered root, and of a rather bitter, not very disagreeable taste, persistent in its character. It is insoluble in water, ether, the mineral acids, acetic acid, also in volatile oils, oil of turpentine, and chloroform, floating on the surface of this last. Ammonia added to it in water, causes it to be nearly completely dissolved, and gives a dense, light bluish-yellow solution. Liquor potassa, likewise causes it to imperfectly dissolve in water, giving a dark-yellow precipitate, and a light yellow saponaceous solution. It is partially soluble in alcohol, and on the addition of ammonia becomes entirely dissolved, but gives a precipitate on standing. Sulphuric acid turns it a dark yellowish-red color; nitric acid yellowish-green ; and muriatic acid affects no change in its color. Dose, of the decoction, made by boiling one ounce of the powdered bark in two pints of water, down to one pint—one tablespoonful every 18 274 Materia Medica. 1,2, or 4 hours as required—if it purge, produce nausea, or a disagree- able relaxation of the nervous system, lessen the dose, or omit its use entirely, for a time; of the hydro-alcoholic extract, 1 to 4 grains every 2, 3, or 4 hours. The Baptisia Alba, or Prairie Indigo of the western prairies, with the flowers white, may be substituted for the above. Off.

Syst.—Pentandria Monogynia. the leaves. Description.—This plant formerly belonged to the genus Diosma,, but has been transferred by Botanists to that of Barosma. It is a slender, smooth, upright, perennial shrub, between two and three feet in hight, with twiggy, somewhat angular branches, of a brownish-purple color. The leaves are opposite, spreading, about an inch long, ovate, acute, on very short petioles, very obtuse, delicately and minutely crenated, quite glabrous, rigid, darkish-green and quite smooth above, with a very few obscure, oblique nerves, beneath paler, dotted with glands which are scarcely pellucid, while at every crenature is a conspicuous pellucid gland. The flowers are whitish, or of a pale-reddish color, solitary, on short pedicels at the ends of short lateral shoots. The calyx has five ovate- acuminate, persistent sepals, green, tinged with purple, beneath which are two or three pairs of small imbricated bracteas. The corolla has five elliptic, oblong, bluntish petals, somewhat spreading, which are purple when in bud, and blush-colored when fully expanded. The sta- mens are five, subulate, and bearing ovate, incumbent anthers ; filaments slightly villous. The ovary is superior, turbinate, supporting an erect style crowned with a minute, five-lobed stigma. The capsule is ovate, containing a single, oblong, black, shining seed, with an elastic testa. History.—This plant is a native of southern Africa, the officinal part of which is the leaf. There are several varieties from which the leaves are obtained, as the Barosma Crenata, B. Crenulata, B. Serratifolia, etc. The leaves are odoriferous, and when powdered are termed by the Hot- tentots, Booko or Buchu, and are used by them to rub upon their greasy bodies. They likewise prepare a Buchu Brandy by distilling the leaves with wine, and which they employ as an efficient remedy in all affections of the stomach, bowels, and bladder; they also apply a decoction of the leaves to wounds. Benzoin Odoriferum. 275 As found in our markets, the leaves are from three-quarters of an inch to an inch in length, from three to five lines broad, elliptical, lance- olate-ovate, or obovate, sometimes slightly pointed, sometimes blunt at the apex, very finely notched and glandular at the edges, smooth, green on their upper surface, dotted and paler beneath, and of a firm consist- ence. They have a strong, diffusive, aromatic odor, with very faint bit- terness ; the taste and odor being somewhat allied to pennyroyal, and which will serve to distinguish them from senna leaves. If they be pre- served with ordinary care, their odor will remain for some years. The leaves of the B. Serratifolia may be known by their linear-lanceolate form, and serrulate edges ; and those of the B. Crenulata much resemble those of the B. Crenata, but are oblong-ovate, and have a narrow pellu- cid margin around the whole leaf. They all possess similar properties. Analysis has detected in them, a light, yellowish-brown, and highly odorous volatile oil, gum, extractive, which is precipitated by infusion of galls, chlorophylle and resin. Water or alcohol extracts their virtues, which are chiefly dependent on the volatile oil and extractive. Properties and Uses.—Buchu is a stimulant, diuretic, antispasmodic, and tonic. Useful in all diseases of the urinary organs attended with increased uric acid; in irritation of the bladder and urethra attending gravel, in catarrh of the urinary bladder, and incontinence connected with diseased prostate. It has also been recommended in dyspepsia, dropsy, cutaneous affections, and chronic rheumatism. I do not, how- ever, think it equal to many of our indigenous remedies, which are sadly neglected by the profession, in their eagerness for something at a distance from home. Were our native plants more closely investigated, there would be but little use for foreign, and consequently expensive agents. Under favorable circumstances a warm infusion of Buchu leaves, will cause diaphoresis. Dose of the powder, from twenty to thirty grains, two or three times a day; of the infusion, two to four ounces, three or four times a day; of the tincture, one to two fluidrachms. Off.

Description.—Benzoin Odoriferum, or the Laurus Benzoin of Linnaeus, is sometimes known as Spicebush, Feverbush, Wild Allspice, Benjamin- 276 Materia Medica. Bush, etc. ; it is a shrub growing from five to twelve feet in hight, with obovate-lanceolate, veinless, entire, deciduous leaves, green on each side, and slightly pubescent beneath; flowers yellow, in little naked umbels on the naked branches, often dicecious; buds and pedicels smooth; fruit the size of an olive, bright-red, in clusters, containing an ovate, pointed nut. Calyx six-cleft, with oblong segments. History.—This shrub grows in moist, shady places, in all parts of the United States; it bears greenish-yellow flowers in April, which are suc- ceeded by small clusters of oval berries, and which in the latter part of September, when ripe, are of a shining crimson color. The whole plant has a spicy, agreeable flavor, which is strongest in the bark and berries, and which is communicated to boiling water, or proof spirit. Properties and Uses.—Aromatic, tonic, and stimulant. An infusion or decoction has been successfully used in the treatment of intermittents, and low forms of fever, also as an anthelmintic. The berries afford a stimulant oil, much esteemed as an application to bruises, chronic rheu- matism, itch, etc., and has some reputation as a carminative in flatulence, flatulent colic, etc. The bark, in decoction, is said to be refrigerant and exhilarating, and exceedingly useful in all kinds of fever, for allaying excessive heat and uneasiness; a warm decoction is employed to produce diaphoresis. The decoction may be drank freely. BENZOINUM. Benzoin. Nat. Ord.—Styracaceae. Sex. Syst.—Decandria Monogynia. THE concrete juice of styrax benzoin. Description. — Styrax Benzoin is a tall tree of quick growth, with many strong, round branches, covered with a hoary and fine whitish downy bark. Its leaves are alternate, on short petioles, ovate-acuminate, entire, smooth above, and tomentose beneath. The petioles are round, striated, channeled, tomentose. The flowers are in compound axillary racemes, nearly the length of the leaves, usually hang all on the same side, with angular downy peduncles, and a few, tomentose, oblong, deciduous bracts. The calyx is campanulate, downy, and minutely five- toothed ; the corolla is longer than the calyx and is five-cleft, the seg- ments are linear, and obtuse, somewhat silky rather than tomentose. Stamens ten ; filaments connected below into a tube almost as long as the calyx, and bearing linear, erect anthers. The ovary is superior, ovate-tomentose, with a filiform style and simple stigma. The fruit is a drupe of a globose form containing one or two angular nuts, convex on one side, and concave on the other. Benzoinum. 277 History.—This tree is a native of Sumatra, Borneo, Java, Siam, etc., where it is cultivated; it is called Benzoin Tree or Benjamin Tree, and furnishes the benzoin of commerce. This resinous balsam is obtained by making incisions into the bark of trees six or seven years old, from which the balsam exudes in the form of a thick, white, resinous juice, which is allowed to remain for three months before it is collected, when new incisions are made. There are several varieties of benzoin, the best of which are in tears of a whitish color, and united by a reddish- brown connecting medium; the brown or blackish masses, which are more common, usually contain many impurities, and are inferior to the tears. Benzoin is firm, brittle, pulverizable, of an agreeable balsamic odor when rubbed, and of a sweetish, balsamic, somewhat acrid taste. When pure, it is wholly soluble in alcohol or ether. When heated, thick, white, pungent fumes of benzoic acid are given out, which cause cough- ing when inhaled. In pulverizing it, sneezing is apt to be induced. Water added to its alcoholic solution, precipitates it, rendering the liquor milky, and which has been heretofore much used as a cosmetic, under the name of Virgin's Milk. Its specific gravity is from 1.06 to 1.09. It contains volatile oil, resin, a balsamic matter, aromatic extractive, with a large proportion of benzoic acid. Properties and Uses.—Stimulant and expectorant, and has some in- fluence on the sexual organs. It enters into the manufacture of elixir paregoric, and constitutes the basis of Turlington's and many other balsams, which exert a salutary influence in healing wounds; the tincture is also employed to form a coating over the adhesive preparation so well known as Court Plaster. The fumes or vapor inhaled into the lungs, has been strongly recommended in chronic laryngitis. But principally used to prepare benzoie acid, to improve the taste and odor of other medicines, and in perfumery. A preparation has been recently used with some degree of success in hemorrhages, called Pagliari's Haimostatic or Styptic. It is made by boiling together for six hours in a glazed earthen vessel, Alum one pound, Tincture of Benzoin eight ounces, Water ten pounds. As the water evaporates it must be constantly replaced by hot water, so as not to interrupt the ebullition, and stir the resinous mass round constantly. Then filter the fluid and keep in stoppered bottles. It is limpid, color of champagne, styptic in taste, and aromatic in odor. White resin has been successfully substituted for the benzoin. Every drop of this fluid poured into a glass containing human blood produces an instantaneous magma; and by increasing the proportion of the styptic to the quantity of the blood, a dense, homogeneous, blackish mass results. It is said to be useful in all arterial and venous hemorrhages. In applying it, lint and bandages should be used to prevent the coagula which forms from being 278 Materia Medica. removed from the mouths of the vessels ; an application of them for twenty-four or forty-eight hours is sufficient.

Description.—Berberis Vulgaris is an erect, deciduous shrub, from three to eight feet high, with long, bending branches which are dotted with triple spines. The leaves are obovate-oval, simple, closely serru- late, crowded, forming fan-like groups, alternate, from one and a half to two inches long, and about one-third as wide, tapering at their base into the petioles, with small thorns at their base, which are a transformation of the primary leaves. The fiowers are many, on slender and pendulous racemes, yellow, small, and succeeded by loose branches of bright-red berries, of an oblong form, of a pleasant acidulous taste. History. — This shrub is found from Canada to Virginia, on hills, mountains, and among rocks; it is rare in the west and in rich soils. It flowers in April and May, and ripens its fruit in June. Berberine is its active alkaline principle. Properties and Uses. — Tonic and laxative. Used extensively by practitioners in the New England States, in all cases where tonics are indicated, also in jaundice, and chronic diarrhea and dysentery. The berries form an agreeable acidulous draught, useful as a refrigerant in fevers, also beneficial in dysentery, cholera-infantum, diarrhea, etc. The bark is bitter and astringent, and has been used with advantage as a tonic, and has proved efficacious in the treatment of jaundice. The bark of the root is the most active; a teaspoonful of the powder will act as a purgative. A decoction of the bark or berries, has been found of service as a wash or gargle in aphthous sore-mouth, and in chronic ophthalmia. BERBERINA. THE ALKALINE PRINCIPLE OF BARBERRY. Preparation.—An alcoholic extract of the Berberis Vulgaris is pre- pared, to which water is added. This throws down a pulverulent brown substance; the fluid is then poured off, and the substance dried; it is Betula Lenta. 279 then treated with alcohol, which takes up the Berberine, leaving a small portion undissolved. By evaporating the alcohol the berberine remains. It resembles an extract, and is of a brownish-yellow color, translucent, with the smell of the root, and a pure, bitter taste; it becomes soft in the air. It is soluble in alcohol. Berberine may be obtained in crystals. Properties and Uses.—Tonic and laxative, operating similar to a com- bination of rhei and hydrastis. Used in the same cases as the root. Dose, two to ten or even twenty grains. This article is not sufficiently used by Eclectics. BETULA LENTA. Black Birch. Nat. Ord.—Betulaceae. Sex. Syst.—Monoscia Polyandria. BARK. Description.—Betula Lenta, also known as Cherry Birch, Sweet Birch, Mahogany Birch, etc., is a large tree growing from fifty to seventy feet in hight, with a diameter of from two to three feet. The leaves are cordate-ovate, acuminate, acutely and finely doubly serrate, hairy on the veins beneath, and on the petioles. Fertile aments erect, elliptical, thick, somewhat hairy; sterile aments two to three inches long, longer than the fertile, and not so thick; lobes of the veiny scales nearly equal, obtuse, diverging. History.—This is a well known tree, growing in various parts of the United States. The trunk is invested with a dark-brown or reddish bark, which becomes rough in old trees, and has, together with the leaves, an aromatic flavor and taste, somewhat similar to Gaultheria Procumbens. The wood is of a reddish color, strong, compact, and takes a fine polish ; it is much used in cabinet work. The cambium is used in the spring by boys, as a delicious morsel. The bark is the part used, and yields its properties to water. Properties and Uses.—Gently stimulant, diaphoretic, and astringent. Used in warm infusion wherever a stimulating diaphoretic is required, also in diarrhea, dysentery, cholera-infantum, etc. In decoction or syrup, it forms an excellent tonic to restore the tone of the bowels, after an attack of dysentery. Said to have been useful in gravel, and female obstructions. 280 Materia Medica. BIDENS BIPINNATA. Spanish Needles. Nat. Ord.—Asteraceas. Sex. Syst.—Syngenesia Frustranea, ROOT AND SEEDS. Description.—Bidens Bipinnata is an annual plant, with a smooth, branched stem growing from one to four feet high ; the leaves are bipin- nately parted, nearly smooth, petioled ; the leaflets are ovate-lanceolate, pinnatifid, mostly wedge-shaped at the base; heads of flowers on slender peduncles, each with three or four obscure, obovate, yellow rays; outer involucre of linear scales as long as the inner, and nearly as long as the short, pale, yellow rays ; achenia long and slender, four-grooved and angled, nearly smooth, three or four awned, which adhere to the dress and to the fleece of animals. History.—This is a common plant, growing in waste places on dry soils, flowering from July to September, and found from Connecticut to Pennsylvania, and westward. The Bidens Frondosa, common Beggar-Tick, has a smooth, branching, rather hairy stem, from two to six feet high; the leaves are three to five, divided; leaflets lanceolate, pointed, coarsely toothed, mostly stalked; outer leafy involucre much longer than the head, ciliate below ; rays none ; flowers in clusters at the end of the branches, yellow; achenia wedge-obovate, two-awned, the margins ciliate with upward bristles, except near the summit. This is a common, very troublesome weed, growing in moist, cultivated fields throughout the United States; the achenia, as in the other species, adhering by their retrorsely-barbed awns to clothes, etc. It flowers from July to September. The Bidens Connata (Bidens tripartita,) Cuckold, or Swamp Beggar's Tick, has a smooth stem, four-furrowed, with opposite branches, and grows from one to three feet high. The leaves are lanceolate, opposite, serrate, acuminate, slightly connate at the base, the lower ones mostly trifid ; the lateral divisions united at the base, and decurrent on the petiole ; scales of the outer involucre longer than the head, leafy, mostly obtuse, scarcely ciliate ; rays none ; achenia narrowly wedge-form, two, three, or four-awned, and with downwardly-barbed margins. Flowers terminal, solitary, consisting only of the tubular, yellow florets, sur- rounded by a leafy involucre. This is likewise a common weed found in wet grounds, rich fields, swamps and ditches, from New England to Missouri. It flowers in August. The root and seeds of all these plants are employed medicinally, and may be used in decoction, infusion, or tincture. Brayera Anthelmintica. 281 Properties and Uses.—Emmenagogue and expectorant; the seeds in powder or tincture have been successfully used in amenorrhea, dysmen- orrhea, and some other uterine derangements; and an infusion of the root has proved beneficial in severe cough. The Bidens Connata has likewise been recommended in the above affections, also in palpitation of the heart, in which the infusion or decoction, drank freely through the day, has been found effectual. The Bidens Frondosa in infusion has cured several severe cases of croup, even where they have been con- sidered beyond aid. A strong infusion of the plant, sweetened with honey, was administered to the children, warm, in doses of a tablespoon- ful or more every ten or fifteen minutes, until it vomited. A quantity of mucous and membranous shreds were ejected, followed by immediate relief; the children passed into a sleep, from which they awakened per- fectly well. In a few hours after the emetic operation of the warm infu- sion, it acted as a cathartic. The leaves from which the infusion was made, were, at the same time, placed in a piece of flannel with some brandy added to them, and laid over the chest and throat. This plan is also beneficial in colds, acute bronchial and laryngeal attacks from expo- sures to cold, etc. BRAYERA ANTHELMINTICA. Kousso. Cossoo. Nat. Ord.—Rosacea?. Sex. Syst.— THE FLOWERS. Description.—This is a tree growing about twenty feet high, with round, rusty, tomentose-villose branches, marked by the annular cica- trices of the fallen leaves. The leaves are crowded, alternate, interrupt- edly imparipinnate, and sheathing at the base ; leaflets oblong, or ellip- tical-lanceolate, acute, serrate, villose at the margin and on the nerves of the under surface. Stipules adnate to the petiole, which is dilated at the base, and amplexicaul. Flowers dicecious, small, greenish, and becoming purple ; repeatedly dichotomous; the pedicles with an ovate bract at the base. The so-called male flowers may be regarded as her- maphrodite flowers, inasmuch as the carpels are well developed. The female flowers are somewhat different in their structure. The outer seg- ments of the calyx are much more developed than in the female flowers, and are four or five times larger than those of the inner row, and are placed somewhat below them ; the petals are entirely wanting; the sta- mina are rudimentary and sterile. The ripe fruits are unknown. History.—This plant was introduced into notice by a pharmacien of Paris, and its properties as an anthelmintic were investigated by the 282 Materia Medica. Academy of Medicine, as early as 1847 ; who, with the Academy of Sciences, made a favorable report. It grows in Abyssinia, the flowers being the parts of the plant used; they are reduced to a fine powder, which is brownish, like jalap, bitter, somewhat nauseous, and an odor similar to scammony. The plant is named in honor to Dr. Brayer, who first made its virtues known in Europe. Bruce, in his travels, vol. vii, appendix, gives a minute description of the plant, and calls it, in testi- mony of esteem for a friend, " Banksia Abyssinica." Dr. Kirk, in the appendix to the second volume of the " Highlands of Ethiopia," by Sir W. C. Harris, calls it " Hagenia Abyssinica," and states "that a cold infusion of the dried flowers and capsules, constitutes the famous drasti- cum purgans and anthelminticum of the Abyssinians." Properties and Uses. — Purgative and anthelmintic. Used by the Abyssinians for tapeworm, to which they are very subject, and it is said they will not travel without having some of the Kousso with them. The dose of the flowers in powder is a small handful, or about four drachms and a half, which is to be macerated in about three gills of lukewarm water for fifteen minutes. The infusion, with the powder suspended in it, is taken either in one, two or three doses, quickly following each other. It is recommended that lemon-juice, or tamarind water, should be taken freely before and after the Kousso. The patient must be pre- pared by low diet for one or two days previously, and by a dose of castor oil, or other purgative, and the Kousso is to be taken on an empty stomach before breakfast. The clear infusion has the color, and a some- what similar taste, to very weak senna tea. Its operation is safe, speedy, and most effectual, rarely causing any annoyance or uneasiness, except a slight nausea, and this but seldom ; occasionally emesis takes place, or diuresis. A gentle cathartic after its operation is also advisable. As far as it has been used, it has not failed to kill and expel the worm. BUXUS SEMPERVIRENS. Box. Nat Ord. — Euphorbiaceas. Sex. Syst. — Moncecia Tetrandria, THE LEAVES. Description. — Buxus Sempervirens is a small, dense-leaved, hard- wooded, evergreen tree. The leaves are ovate, opposite, deep shining green, becoming red in the autumn, quite smooth and entire, with the cuticle of the underside readily stripping off; petioles and young branches slightly downy; flowers aggregate, axillary, pale-yellow. Capsule glob- ular, three-horned, tricoccous, six-seeded, bursting elastically. Seeds parallel, oblong, slightly compressed, externally rounded. Calendula Officinalis. 283 History.—This is an exotic though generally well-known plant, grow- ing on dry chalky hills in Europe, and the west of Asia. One variety of it, the B. Suffruticosa, Dwarf-box, with obovate leaves, and a stem scarcely woody, and which is much esteemed for borders along the walks of gardens, possesses similar medical virtues. It is of very slow growth, a tree eight feet high must be one hundred years old. The wood is yellow, very hard, and much used by wood-engravers for wood- cuts, also for other purposes. The leaves, which are the parts used, are bitter and nauseous, and impart their properties to water or alcohol. Properties and Uses. — Cathartic, sudorific, alterative, and anthel- mintic. It may be used in syrup or extract, in all diseases where an alterative is required ; said to be an equivalent of Stillingia in syphilis, but I have used the plant somewhat extensively, and do not consider it near as effectual. In doses of ten or twenty grains of the powdered leaves, it proves an excellent vermifuge. The dose of a strong decoc- tion or syrup, is from half an ounce to an ounce, three or four times a day. And in combination with the Stillingia and Corydallis, in the form of syrup, it forms one of the best antisyphilitic remedies known in prac- tice. Reputed to possess antispasmodic virtues, and to have been bene- ficially used in epilepsy, chorea, hysteria, etc., but requires further corroboration. Chips of the wood are said to have the same properties, and have been prescribed in syphilitic diseases, and chronic rheumatism. A fetid empyreumatic oil, oleum buxi was formerly prepared, but the use of which has become superseded by the preparations of Guaiacum; it has, however, been successfully used in toothache. Camels who eat the leaves are said to become poisoned. CALENDULA OFFICINALIS. Garden Mary gold. Nat. Ord.—Asteracea?. Sex. Syst.—Syngenesia Necessaria. THE LEAVES AND FLOWERS. Description.—Calendula Officinalis has a fibrous, annual root, with a stem about a foot high, having many patent dichotomous, or sometimes trichotomous branches, striated, green, succulent, hispido-pubescent. The leaves are alternate, oblong, acute, mucronate, sessile, somewhat succu- lent, broad, and a little cordate at the base, the margins quite entire, and often scabrous-ciliate. Flower-heads large, terminal, solitary upon each branch, of a rich, full golden yellow, deeper and brighter previous to their full expansion. Involucre of many nearly equal, appressed, linear- subulate, pilose-hispid leaves or scales, not one-third so long as the 284 Materia Medica. radiant florets, the apices a little recurved. Achenia carinate, muricate, incurved. Corollas of the ray ligulate, female tridentate, broadly linear, the lower tubular portion hairy. Ovary singularly boat-shaped, curved like a horse-shoe, large, green, downy within, having a thickened mar- gin, more or less tuberculated on the back. Florets of the center all tubular, small, male, and consequently sterile ; the mouth five-cleft, base hairy. Abortive ovaries cylindrical, downy, green. Receptacle dotted. History.—This is a well-known garden plant, with a feeble, aromatic, not very unpleasant smell, and a bitter, rough, saline taste. The leaves and flowers are generally used, and impart their active properties to alco- hol, or boiling water. Properties and Uses.—Slightly stimulant and diaphoretic. Used for similar purposes with saffron, but less active. Has been reputed anti- spasmodic, deobstruent, and emmenagogue, and recommended in low forms of fever, scrofula, jaundice, amenorrhea, cancer, etc. Used in infusion, or in the form of extract, from four to six grains, three or four times a day ; also applied locally to cancerous and other ulcers. Pro- bably over-estimated. Dr. Wm. J. Clary of Monroeville, Ohio, writes me as follows, in relation to this plant: "As a local remedy, after sur- gical operations, it has no equal in the Materia Medica. Its forte is its influence on lacerated wounds, without regard to the general health of the patient, or the weather. If applied constantly, gangrene will not follow, and I might say there will be but little, if any danger of tetanus. When applied to a wound, it is seldom that any suppuration follows, the wound healing by replacement or first intention. It has been tested by several practitioners, and by one, is used after every surgical operation with the happiest effect. You need not fear to use it in wounds, and I would not be without it, for a hundred times its cost. It is to be made into a saturated tincture with whisky diluted with one-third its quantity of water ; lint is saturated with this, applied to the parts, and renewed as often as it becomes dry." CALX. Lime. Preparation.—Lime does not exist in the pure or caustic state in nature, but is obtained from some form of the native carbonate, which is cal- cined by an exposure to strong heat; the carbonic acid is thus driven off, and the lime remains. It is usually procured from common lime- stone, which, however, contains several impurities. A purer lime may be obtained from chalk; and when intended for nice chemical operations white marble or oyster-shells should be used. These may be reduced to small fragments, placed in a covered crucible, and exposed to a full Calx. 285 red heat for three hours; after the lime has become cool, it should be at once secured in well-closed vessels, to prevent it from absorbing carbonic acid from the atmosphere, which it does very speedily. History.—Lime is a grayish-white, brittle, earthy-like substance, of a strong, alkaline, caustic taste, infusible, except under the compound blow-pipe, of the specific gravity 2.3. It rapidly absorbs moisture and carbonic acid from the atmosphere, reducing the air to a state of perfect dryness, and falls into a white powder, which is a mixture of carbonate and hydrate. It has an alkaline reaction. If carbonic acid be present, the effervescence will take place on dissolving the lime in muriatic acid, but not without. Lime is not readily soluble in water, it requiring about seven hundred times its weight of temperate water for entire solution ; hot water dissolves it less readily. A thick liquid, called Milk of Lime is made by mixing lime with an excess of water. When water is added to lime, it cracks and becomes reduced to powder, with the evolution of heat. Hydrate of lime or slaked lime is prepared by adding water to quicklime, by small quantities at a time, until it falls to powder; it is white, pulverulent, and much less caustic than lime ; it is used princi- pally for preparing chlorinated lime. Lime is the oxide of calcium, and consists of one equivalent of cal- cium 20.5, and one of oxygen 8, = 28.5. It forms a very deliquescent salt by reaction with muriatic acid, and a sparingly soluble one with sul- phuric, by which it may be determined from other alkaline earths. It is incompatible with all acids, acidulous, metallic, and ammoniacal salts, borates, alkaline carbonates, and astringent vegetable infusions. Properties and Uses.—Internally, see Aqua Calais. Externally, as an escharotic. Mixed with caustic potassa it forms the Potassa cum Calce, a powerful caustic, for cauterizing the neck of the uterus, or other parts. This caustic, also known as Vienna powder or paste, is made by reducing caustic potassa one ounce and a half, and quicklime two ounces, each separately, to powder in a heated mortar; then mix them carefully and rapidly, and keep the mixture in a wide-mouthed bottle with a ground stopper. In using this caustic, the powder must be moistened with a little alcohol, so as to reduce it to a soft paste, which is to be applied to the part to be cauterized. In this case, the potassa only acts upon a circumscribed portion of skin, instead of spreading, as common caustic potassa generally does: but to bound the space still more accu- rately, it may be surrounded by a ring of diachylon plaster. Dr. Filhos has prepared a caustic of the same agents, which is more easily used, it is called the Caustic of Filhos. It is made by fusing together six ounces of caustic potassa, and three ounces of quicklime ; the mixture is poured into leaden cylinders inclosed in glass tubes, and which are to be sealed afterward at each end. In cases where diaphoresis is desirable, without disturbing the patient, it may be effected as follows: Take a piece of lime about the size of a 286 Materia Medica. Sicily orange, wrap around it a wet rag, but not too wet. Around this wrap several thicknesses of dry muslin or cloth. Place one thus pre- pared on each side of the patient, and by both thighs ; it will soon induce copious perspiration. Off. Prep.—Aqua Calcis ; Liquor Calcis ; Potassa Cum Calce. CAMPHORA. Camphor. Nat. Ord.—Lauraceas. Sex. Syst.—Enneandria Monogynia. Camphor is a peculiar concrete substance derived from Laurus Cam- phora and purified by sublimation. It is chiefly brought to this country from Canton, in the crude state, and undergoes purification before it can be used for medicinal purposes. Description.—Laurus Camphora is an evergreen tree of considerable size, with a trunk straight below, but divided above into many drooping, smooth branches, covered with a greenish bark. The leaves are alter- nate, on long footstalks, ovate-lanceolate, somewhat coriaceous, entire, smooth, bright-green and shining above, paler beneath, triple-nerved, with a depressed gland opening by a pore at the axils of the principal lateral veins beneath, and two or three inches in length. Petioles an inch to an inch and a half long, slender, smooth. Panicles axillary and ter- minal, corymbose, naked. Leaf-buds scaly. Flowers small, white, smooth externally, pedicelled, and in clusters. History.—The Camphor tree is a native of Japan, China, the East Indies, etc. It is an aromatic tree, all parts of it yielding the odor of camphor. Camphor is obtained in Japan by cutting the wood, roots, etc., of the tree in small pieces, boiling them in water, in large iron vessels, over which are placed earthen capitals, containing rice-straw cones. The heat sublimes the camphor, which rises into the capital and condenses upon the straw. In China, the process is somewhat different; the pieces of the tree are boiled in water until the camphor concretes upon the stick used in stirring; the liquor is then strained and allowed to cool, when the camphor hardens. This is then placed in alternate layers with finely powdered dry earth, in a copper basin, on which another is inverted, and heat being applied, the camphor sublimes and adheres to the upper vessel. In this state it is impure, and of a dirty-grayish color, being known as Crude Camphor; it is re-sublimed for pharmaceutical and other uses. Camphor has a crystalline texture; white, translucent and shining, brittle, but somewhat elastic, of a powerful, penetrating, diffusible odor, and of a pungent, bitter, cooling taste. It cannot be pulverized alone, Camphora. 287 but is easily so by the aid of a few drops of alcohol. It slowly evapor- ates when exposed to the air, and is soluble in alcohol, ether, fixed and volatile oils, and acetic, nitric, and sulphuric acids. Nitric acid converts it into camphoric acid and oil of camphor; sulphuric, into artificial tan- nin and charcoal. Resins and fats, when heated with it, unite in all pro- portions. By the application of polarized light, the smallest portion of natural camphor may be distinguished from the artificial camphor (hy- drochlorate of camphene). If small fragments of each be placed sepa- rately on glass slides, and a drop of alcohol added to each, they dissolve and speedily re-crystallize. If the crystallization of the natural camphor is watched by means of the microscope and polarized light, a most beautiful display of colored crystals is seen, while with the artificial cam- phor nothing of the kind is witnessed. Camphor is lighter than water, and keeps up a constant rotatory motion when small fragments are placed on that fluid. It volatilizes at ordinary temperatures, melts at 288°, and boils at 400°. It is considered to be an oxide of camphogene, or cam- phene, which is composed of ten equivalents of carbon 60, and eight of hydrogen 8=68. With one equivalent of oxygen, (Cio Hs 0) cam- phene forms camphor; with four, hydrated camphoric acid; and with half an equivalent of hydrochloric acid, artificial camphor. When camphor is triturated with dragon's blood, guaiacum, galbanum, or assafcetida, the mixture preserves the pilular consistence indefinitely. With benzoin, tolu, mastic, and ammoniac, the mixture becomes soft, by exposure to the air. With olibanum, gamboge, euphorbium, amber, and myrrh, the mixture remains pulverulent, though grumous. Assafce- tida, galbanum, sagapenum, tolu, dragon's blood, olibanum, mastic, benzoin, tacamahac, guaiacum, and ammoniac, destroy to a greater or less extent the odor of camphor. Properties and Uses.—In large doses camphor is a narcotic and irri- tant ; in small ones, sedative, anodyne, antispasmodic, diaphoretic, and anthelmintic. It appears to influence chiefly the cerebral and nervous systems, through the agency of which it affects the circulation. Mucous membranes with which it comes in contact are irritated directly, and acceleration of the circulation may ensue as a secondary effect. It is used to allay nervous excitement, subdue pain, arrest spasm, and some- times to induce sleep. In the delirium, watchfulness, tremors, and starting of the tendons in typhoid conditions, it is of much utility as a nervo-stimulant. In inflammatory affections, as remittent and intermit- tent fevers, acute rheumatism, etc., it acts beneficially as a diaphoretic and sedative ; and is also valuable in gout, neuralgia, dysmenorrhea, after-pains, puerperal convulsions, and painful diseases of the urinary organs, acting as a sedative, anodyne, and antispasmodic. It is often advantageously combined with opium in chordee, and hysteric nympho- mania, and all irritations of the sexual organs. By some physicians it is said to act as an aphrodisiac, exciting the urinary and genital organs 288 Materia Medica. causing a burning sensation along the urethra, and voluptuous dreams , by others again, it is used as an antaphrodisiac, and to allay urinary and genital irritations. It is said to be an antidote to poisoning by strychnia. An oleaginous injection of camphor in the early stage of gonorrhea, often allays urethral irritation; also, the tenesmus from ascarides and dysen- tery, when injected into the rectum. It enters into many embrocations and liniments for rheumatic, neuralgic, and deep-seated pains, cynanche tonsillaris, contusions from blows, sprains, chilblains, chronic cutaneous diseases, and as a stimulant for indolent and gangrenous ulcers. The vapor of camphor, inhaled into the lungs has been found beneficial in asthma and spasmodic cough ; and the powder may be used as a snuff for the relief of nervous headache, and catarrh in its commencing stage. The best form of using this agent is the aqua- camphorae. The admin- istration of opium will best counteract the injurious effects of an over- dose of camphor. Dose of the powder, one to ten grains. When given in the solid form, it is capable of producing ulceration of the gastric mucous membrane. Off.

CANELLA ALBA. Canella. Nat. Ord.—Meliaceas or Canelleaa. Sex. Syst.—Dodecandria Monogynia. BARK. Description.—Canella Alba is a tree with a very straight and upright stem, growing from ten to fifty feet in hight, and branched only near the top. It is covered with a whitish bark; the inner bark is thick, smooth, pale, with a pungent, aromatic taste, dry and crumbling between the teeth. The branches are erect and spreading; the leaves are petiolated, irregularly alternate, oblong, obtuse, entire, of a dark-green color, shining and coriaceous, dotted when young, opake when old. The flowers grow at the extremities of the branches in clusters, they are small, of a violet color, and are seldom fully expanded. The calyx is five-leaved and persistent; the sepals are roundish, smooth, concave, and membranous. The petals are much longer than the sepals, oblong, Canna. 289 erect, concave, thick, deciduous, two somewhat narrower than the others. Stamens monadelphous, forming an urceolate tube, to the outer- side of which the anthers adhere. The ovary is superior, ovate, three- celled, bearing a cylindrical style with three convex, blunt stigmas. The fruit is an oblong, fleshy, smooth, black berry, which is three- seeded, or by abortion one-celled, and one or two-seeded. The seeds are exalbuminous, with linear cotyledons. History.—A South American tree; the bark is of a pale orange yellow color externally, and yellowish white on the inner surface, with an aromatic odor, and a warm, bitterish, very pungent taste. Alcohol extracts its active properties, giving a bright-yellow tincture, which is rendered milky by the addition of water. It pulverizes readily, yielding a yellowish-white powder. By distillation with water, a large propor- tion of a fragrant, essential oil is obtained, of a reddish or yellowish color. It contains two oils, mannite, bitter extractive, resin, gum, starch, albumen, and various saline substances. Properties and Uses.—Aromatic stimulant and gentle tonic. Useful in debilitated conditions of the digestive organs; generally prescribed in combination. In the West Indies it is used as a condiment, and has been advised in scurvy. Some smokers add this bark to their smoking- tobacco to remove the unpleasant odor from the tobacco, and to impart a degree of fragrance to their smoking-rooms. CANNA. Canna Starch. History.—Canna Starch, called by the French " Tous les Mois," is the fecula of an undetermined species of Canna. Some suppose it to be obtained from the root or rhizome of the Canna Coccinea, and others of the Canna Edulis. Both suppositions, however, are very uncertain. Canna Starch comes from the West India island, St. Kitts. Be its origin what it may, it is an excellent arrowroot. It is in the form of a light, beautifully white powder, with a satiny appearance, very unlike the ordinary forms of fecula; it looks more like potato-starch than any other variety of fecula, and its granules are larger, being from the 300th to the 200th of an inch in length. Under the microscope these granules are oval or oblong, usually more or less ovate, with numerous, regular, closely set, and unequally distant concentric rings, and a circu- lar hilum, usually at the smaller extremity, and occasionally double, from which proceed the cracks observable in some of the larger grains. This starch has the ordinary chemical properties of common starch, and forms, when prepared with boiling water, a stiff jelly. 19 290 Materia Medica. Properties and Uses.—Canna starch forms a nutritious and wholesome food for infants and invalids. It may be pi»epared in the same manner as arrowroot, and may be used in the same cases. By many it is pre- ferred to any other kind of arrowroot. CANNABIS SATIVA. Hemp. Nat. Ord.—UrticaceaB or Cannabinaceaa. Sex. Syst.—Dioecia Pentandria. the dried tops and resin. Description.—Cannabis Sativa is an annual plant, growing about three feet high, covered with a very fine, rough pubescence, scarcely visible to the naked eye. The stem is erect, branched, bright-green, angular. The leaves are alternate or opposite, on long, lax petioles, digitate, scabrous, with linear-lanceolate, sharply-serrated leaflets, tapering into a long, smooth, entire point; stipules subulate. Flowers in axillary clus- ters, with subulate bracts; the males lax and drooping, branched and leaf- less at the base; females erect, simple, and leafy at the base. Calyx of male, downy; of female, covered with short brownish glands. Ache- nium ovate, one-seeded; seeds roundish-ovate, somewhat compressed, about the eighth of an inch long, of a shining gray color, inodorous, and of a disagreeable, oily, sweetish taste. History.—Hemp is a native of Persia and the northern parts of India, whence it has been introduced into many other countries. The hemp of this country is identical with the eastern plant in its botanical charac- ters, but differs somewhat from it in its physical qualities, the India plant being more powerful in its action on the system, and which is probably owing to the influence of climate, cultivation, etc. In the eastern countries an infusion of hemp is much employed as an intoxicat- ing drink; and it is smoked the same as tobacco, with which it is frequently mixed. An alcoholic extract of the dried tops is the form employed in medicine, which is made by passing the vapor of boiling alcohol from the boiler of a still into the dried plant contained in a con- venient receptacle, and evaporating the condensed liquor at a tempera- ture not exceeding 150° F. The concrete resinous exudation of the plant is known in India by the name of Churrus. Properties and Uses.—Narcotic, and may be used in place of opium in all cases where that drug disagrees with the patient. The churrus is said to alleviate pain, exhilarate the spirits, increase the appetite, pro- duce decided aphrodisia, and cause sleep; and in large doses, to occasion intoxication, a peculiar kind of delirium and catalepsy. The preparation Cantharis Vesica toria. 291 most used is the alcoholic extract; if of good quality, half a grain or a grain will affect the system, while that of the shops will require from ten grains to half an ounce. Alarming effects have been produced by over-doses. Very favorable reports have been made of its effects in cholera, neural- gia, rheumatism, tetanus, and insanity. A tincture of the extract, made by dissolving three grains in a fluidrachm of proof spirit has likewise been used with advantage — the dose to correspond with that of the extract. Ten drops of it every half hour have been administered in cholera; and have been successfully employed in menorrhagia, which had resisted all ordinary means for months; it has also proved service- able in uterine hemorrhage. The following is said to be a certain cure for gonorrhea: take, while in blossom, equal parts of tops of the male and female hemp, Cannabis Sativa, bruise them in a mortar, and express the juice, to this add an equal portion of alcohol. Dose, from one to three drops every two or three hours. The green plant collected in the spring, and two or three twigs placed in or between beds, will, it is asserted, certainly and effectually cause bedbugs to remove from the room in which they are used.

Tarsi entire ; nails bifid ; head not produced into a rostrum ; elytra flexible, covering the whole abdomen, linear semicylindric ; wings perfect; maxillce with two membranaceous laciniae, the external one acute within, subuncinate ; antennae longer than the head and thorax, recti- linear ; first joint largest, the second transverse, very short; maxillary palpi larger at tip.—Say. History.—There are a number of insects inhabiting various sections of the world which possess acrid properties, and which, when applied to the skin produce vesication; the most common in use are those under present consideration, Spanish Flies, or Cantharides, the Cantharis Vesicaloria of Latreille, Meloe Vesicatorius of Linnaeus, or Lytta Vesica- toria, and Cantharis officinalis of other naturalists. At what period they were introduced into the practice of medicine is a matter of uncertainty. The Spanish fly is a native of Europe, and is imported into this country from Messina and St. Petersburg. Those from Russia are the best, and may be known by their greater size, and somewhat copper color. This insect may be distinguished from other analogous ones, by present- ing two wing covers of a shining-green color, long and flexible, which cover two membranous wings of a brownish color; the head is large 292 Materia Medica. and heart-shaped, having two thread-like, black, jointed antennae ; the thorax is short and quadrilateral, and along the head and chest is a longitudinal furrow. The fly is about six or ten lines long, and weighs about two grains and a half. They have a peculiar, disagreeable odor, and a faint resinous taste, followed by acridity. In the countries which they inhabit they are found on certain trees as the elder, plum, rose, white poplar, privet, elm, lilac, ash, and honeysuckle, the leaves of which serve them as food. In the state of larva, they inhabit the earth, and prey upon the roots of plants. In the months of May and June, they come forth in swarms in the form of flies, and fill those trees and shrubs which they prefer. At this season they are collected, which is attempted at dawn, when they are torpid from the cold of the night; to undertake their removal in the day-time would be a serious measure. Those who gather them being protected with masks and gloves, shake them from the trees and receive them into sheets spread below; they are then immersed in vinegar or exposed to the vapor of boiling vinegar, spirit, or turpentine, for the purpose of killing them, after which they are quickly dried in the sun, or in heated apartments, and when perfectly dried, are put into casks or boxes lined with paper, and closed so as to exclude as much as possible the atmospheric moisture. It abounds the most in Spain, Italy, Southern France, Southern Russia, Sicily, and is found to some extent in all the South of Europe and in Western Asia. When dried the flies present the form and color above described, together with the disagreeble odor of the living insect, and an acrid, burning, and urinous taste. They are easily pulverized, the powder presenting a dirty grayish-brown color, interspersed with numerous shining-green particles, the fragments of the feet, head, and wing covers. And as these particles resist the process of putrefaction for a longtime, they may consequently be detected in the stomach many months after death occurring from the internal administration of cantharides. When kept perfectly dry, and well closed, the vesicating property of the flies may be preserved for many years. Hence they should always be kept in well stoppered bottles, and powdered only as required. If purchased in powder they may have lost their activity, or suffered from adultera- tion with euphorbium, or some other insects. To preserve them from insects, various means have been advised, as the introduction of a few lumps of camphor into the vessel containing them, or the addition of carbonate of ammonia, or a few drops of strong acetic acid. Exposing them for half an hour in glass bottles, to the heat of boiling water, destroys the insects and eggs, without impairing the virtues of the flies; of course they must not be allowed to come in contact with the water. The properties of the fly are much diminished by the insects which feed upon them. Cantharides powder yields its active properties to boiling water, acetic acid, alcohol, proof spirit, ether, the fixed and volatile oils. The active Cantharis Vesicatoria. 293 principle is a white, crystalline substance, termed Cantharidin, which is soluble in ether, acetic acid, fixed and volatile oils, and in alkaline solu- tions. It is in small, white, pearly prisms, which are neutral, insoluble in water and cold alcohol, but soluble in ether, alkaline solutions, acetic acid, the oils, and in boiling alcohol which deposits it upon coolino-; it fuses at 210°, volatilizes at a higher heat without decomposition, and evaporates slowly at atmospheric temperatures. It is said to exist prin- cipally in the trunk and soft parts of the body, and may be obtained by exhausting powdered cantharides with cold rectified spirit, by percola- tion, concentrating the tincture till most of the alcohol is expelled, and allowing the residue to rest for a long time until crystals form. It may be freed from impurities by elutriation with a little cold rectified spirit, which scarcely acts on crystallized cantharidin; and it may be obtained quite pure by re-dissolving them in boiling rectified spirit, adding animal charcoal, and re-crystallizing them by rest and cooling. Ether is, how- ever, preferred to alcohol in preparing these crystals, as it dissolves less of the green oil, which is very difficult to separate. The composition of cantharidin is carbon 61.68 per cent., hydrogen 6.04, and oxygen 32.28, or Cio He Oi. Cantharides are found to contain in addition to their active principle, a green oil, insoluble in water, soluble in alcohol, and inert as a vesica- tory ; a black matter, soluble in water, insoluble in alcohol, and inert; a yellow viscid matter, soluble in water and alcohol, and inert as a vesicant; a fatty matter insoluble in alcohol; phosphates of lime and magnesia, acetic acid, etc. Although cantharidin is insoluble in water and cold alcohol, yet the decoction and tincture of cantharides possess the active properties of the insect, which is owing to the presence of the yellow matter combined with it. The best menstruum for cantharides is sul- phuric ether, which dissolves only the active constituents. Properties and Uses.—In large doses, narcotic and irritant; in medi- cinal doses, stimulant and diuretic. In large doses, its use is dangerous, being attended often by violent inflammation of the alimentary canal and urinary organs, strangury, irritation of the sexual organs, in the female, abortion ; also, headache, delirium, convulsions and coma. Twenty-four grains of the powder or one ounce of the tincture have produced alarm- ing symptoms. There is no known antidote to its poisonous effects, which must be treated on general principles. Medicinally, they are sometimes given in chronic gonorrhea, gleet, leucorrhea, seminal weak- ness, paralysis and chronic inflammation of the bladder. They have also been reputed useful in the anasarcous swellings succeeding scarla- tina, diabetes, scaly cutaneous eruptions, chronic eczema, incontinence of urine, amenorrhea, etc. Thirty drops of solution of potassa, given every hour, is said to be an effectual remedy in cantharidal strangury. 294 Materia Medica. Dose, of powdered cantharides, half a grain to two grains. (See Tinc- tura Cantharidis.) Externally, cantharides cause redness, vesication, suppuration or sloughing, according to the length of contact with the integuments. Their most general use is to produce vesication. Blisters are sometimes beneficial in tic-douloreux, sciatica, local chronic inflammations, diseases of the brain, chest and abdomen, to excite the languid action of vessels, in recession of exanthematous affections, and to rouse from general defective sensibility, as in typhoid fever. In their application to children, much care should be observed, especially in typhoid conditions, exan- thema, and where a tendency to sloughing exists. A piece of white paper soaked with the Cantharidin, which is greenish and liquid, laid on the part, and covered with a compress, and confined by means of a bandage, will vesicate in three or four hours. A vesicating oil has been recommended by E. Dupuy, prepared as follows: To one part of pulverized cantharides add in a close vessel, a mixture of chloroform and castor oil of each, by weight, one and a half parts; after some hours transfer the ingredients to a glass apparatus, and displace the liquid in the usual way; it will amount to about two-thirds of the original bulk of the liquid employed. A few drops of this vesicating oil applied to the arm of an adult will produce a perfect blister in about eight hours. It is easy of application on any surface, holds the vesicat- ing agent free from the disagreeable concomitants of the ordinary fly- blister, and retains the cantharidin in a soluble state. Its action will probably be favored by the use of oil-silk over the application of it to the skin. Off. Prep.—Tinctura Cantharidis; Emplastrum Cantharidis. CANTHARIS VITTATA. Potato Fly. Description.—The Potato Fly is found principally in the middle and southern States; it makes its appearance in July and August, and feeds upon the potato plant. Some seasons the fly exists in great numbers. It resembles the Spanish Fly, though somewhat smaller, being about five or six lines in length. Its head is of a light-red color, with dark spots upon the top ; the antennae are black; the elytra or wing covers are also black, with a central yellow longitudinal line, and yellow margins; the thorax is black, with three yellow lines; and the abdomen and legs are covered with an ash-colored down. During the season of their appearance, they may be found on the plant in the morning and evening, but during the heat of the day, they descend into the soil. They may Caoutchouc 295 be collected by shaking them from the plant into hot water, after which they should be carefully dried in the sun. History. — The Potato Fly, though not so much employed as the Spanish Fly, is fully equal, if not superior to it as a vesicant; indeed, its effects are found to take place more promptly than with the foreign insect, which may, probably, be owing to its greater freshness. There are several other species of blistering fly in the United States, which are, probably, not at all inferior to cantharides ; as the Cantharis Cinerea, or ash-colored cantharis which inhabits the northern and middle States ; the C. Atrata, or black cantharis, common to the northern and middle States, and likewise found in Barbary; the C. Marginata of the middle and eastern States, and which feeds on the various species of clematis, and also on the cimicifuga; and likewise the C. Alvida, C. Nuttalli, etc. Properties and Uses.—The vesicating property of all these insects, is very likely owing to the presence of the same proximate principle, and therefore they may be applied to the same purposes, and administered in the same doses and preparations as the Spanish Cantharis. CAOUTCHOUC. Gum Elastic. Indian Rubber. Nat. Ord.—Euphorbiaceas. Urticaceas. Sex. Syst.—Moncecia Syngenesia. the gum. Description.—The tree (Ficus Elastica) from which Caoutchouc is obtained has a trunk from two feet to two-and-a-half in diameter, and from forty to sixty feet high. The leaves are alternate, approximated, three foliolate, articulated at the top of a long slendf: stalk, convex below, furrowed above, and swelled at its base ; leaflets smooth, oval, acute, green above, cinereous beneath. Flowers monoecious. Calyx five-cleft. Fruit oblong, greenish, three-cornered, broadest at base, tricoccous, each coccus opening with two valves. Seed ovate, brownish variegated with black, with a thin, brittle testa, and a sweet, nut-like pleasant kernel. History.—This substance is the coagulated or inspissated juice of several tropical trees, the Siphonia Cahuchu, Siphonia Elastica, Jatro- pha Elastica, and Hevea Guianensis, all of which are supposed to be identical. On being wounded, the juice flows out, which is dried on molds of clay, and which comes to us in various shapes. It is gener- ally blackened by smoke, but when pure is nearly colorless ; in thin layers, transparent, highly elastic, lighter than water, without taste or 296 Materia Medica. smell, insoluble in water, alcohol, weak acids and alkaline solutions. It dissolves in pure ether, oil of turpentine, naphtha, coal-tar naphtha, bisulphuret of carbon, and volatile oils. Its solutions in ether, oil of turpentine, and coal-tar naphtha, when dried up, leave the gum in an elastic state, and on this principle water-proof cloth is made ; the same is said to be the case with its solutions in the oils of lavender, sassa- fras and cajuput. Under exposure to heat, caoutchouc first melts, and then distils, yielding a mixture of several oily liquids, all of which, as well as pure caoutchouc itself, are carbo-hydrogens. Caoutchouc is not affected by atmospheric air, chlorine, muriatic or sulphurous acid gas, or ammonia. It consists of 87.2 parts of carbon, and 12.8 of hydrogen. Caoutckoucine is said to be the lightest fluid known, and yet its vapor is denser than the heaviest of the gases. It is prepared by cutting India rubber into small pieces containing about two cubic inches each, placing them into a cast-iron still connected with a well-cooled worm- tub, or any flat vessel with a large evaporating surface, the entire top of which can be removed for the purpose of cleaning it out. Heat is to be applied in the usual way, until the thermometer ranges at about 600° F., when as it progresses upward to this temperature, a dark- colored oil or liquid is distilled over. When the thermometer reaches 600° or thereabouts, nothing is left in the still but dirt and charcoal. This toil is to be rectified, and thereby obtaining fluids varying in specific gravity, the lightest of which has not been under .670. At each rectification the color becomes brighter and paler, until at about specific gravity .680 it is colorless and highly volatile. It must be rectified with one-third its weight of water. To enable the dirt to be removed from the bottom of the still with greater ease, throw in com- mon solder to the depth of about half an inch ; when this becomes fused the dirt is easily taken off. The disagreeable smell of this liquid may be removed by shaking it up with nitro-muriatic acid, in the pro- portion of four fluidounces of the acid to one gallon of the liquid. Mixed with alcohol, caoutchoucine dissolves all the resins, especially copal and india rubber, at the common temperature of the atmosphere, and it speedily evaporates, leaving them again in the solid state. It- mixes Avith oils in all proportions. It promises to be a very valuable article for the solution of resins in the manufacture of varnishes, and for liquefying oil-paints with instead of turpentine. Being very volatile it requires to be kept in close vessels. When caoutchouc is immersed in a bath of fused sulphur, heated to various temperatures, by absorbing the sulphur, it assumes a carbon- ized appearance, and finally acquires the consistency of horn; this is termed Vulcanized caoutchouc. The same vulcanized condition can also be produced either by kneading the india rubber with sulphur, and then exposing it to a temperature of 190°,—or by dissolving the india Capsicum Annuum. 297 rubber in any known solvent, as turpentine, previously charged with sul- phur. Thus treated, caoutchouc remains elastic at all temperatures ; in its ordinary state it is quite rigid at a temperature of 40° ; it is not affected by any known solvents, nor by heat short of the vulcanizing point, and acquires extraordinary powers of resisting compression. A cannon ball was broken to pieces by being driven through a mass of vulcanized caoutchouc, which exhibited no other trace of its passage than a scarcely perceptible rent. This article may be used for various useful purposes, as springs for locks, ornaments, bottles for volatile fluids, as a covering to protect wires from corrosion in sea or on land, life-boats, etc. Properties and Uses.—Caoutchouc is much used for erasing pencil marks ; in forming flexible tubes for chemical purposes, and catheters and bougies for surgical uses. Melted, it is applied as a luting to the joints of chemical apparatus ; in the shape of thin layers, for covering the mouths of bottles, and for other purposes in which the exclusion of air and moisture is requisite. Heated and softened by the flame of a taper, it may be applied, but not while hot, to the cavity of a decayed tooth to relieve toothache, also over leech-bites, to suppress hemorrhage. It has been given in doses of one or two grains, gradually increased, in phthisis, but is seldom or never employed internally. Externally, it has been used as an ingredient of sticking plasters and lfogments. Caoutchouc dissolved in oil of origanum or cajuput, and spread/upon oil-silk or cloth, and allowed to dry, forms an excellent stimulating plas- ter for many local difficulties. CAPSICUM ANNUUM. Cayenne Pepper. Nat. Ord.—Solanaceaj. Sex. Syst.—Pentandria Monogynia. FRUIT. Description.—This is an annual plant, with the stem herbaceous, crooked, smooth, somewhat angular, branching above, and growing from one to three feet high ; the leaves are ovate or oblong, acuminate, smooth, entire, sometimes hairy on the veins underneath, of a dark- green color, and supported on long petioles. The flowers are white, solitary, and stand on long, curved, axillary peduncles. The calyx is persistent, tubular, and five-lobed ; the corolla is monopetalous, wheel- shaped, with a five-cleft limb. The stamens are five, with dark colored, oblong anthers. The ovary is ovate, supporting a filiform style, and terminating in a blunt stigma. The fruit is a long, pendulous, inflated 298 Materia Medica. pod or berry, light, smooth, shining, of a bright scarlet, orange, or yellow color, with two or three cells, containing a spongy pulp, and numerous whitish reniform seeds. History.—There are several species of Capsicum, as the C. Annuum, C. Frutescens, C. Buccatum, C. Minimum, etc. They are natives of the East and West Indies, and of most hot climates throughout the globe, and are cultivated in this country. They all agree in producing c shining vesicular berry of a greenish, yellowish, cherry-red, or most generally scarlet color, consisting of a thin, fleshy, inflated, bilocular, or trilocular capsule, and many small, flat, reniform seeds. The Bird Pepper, C. Minimum, is usually deemed the best; the C. Annuum and C. Baccatum are the most extensively used. The flowers appear in July and August, and the fruit ripens in October. The long, conical, pointed, recurved fruit is that usually employed in medicine. All the varieties of Capsicum have a faint, peculiar odor, and a hot, acrid taste, which in some is so intense that the smallest fragment, when chewed, will excite an insupportable glow of pungency and heat over the whole mouth and throat. This acridity is imparted to hot water, ether, spirit, vinegar, and fixed oils. Powdered Cayenne Pepper, of good quality, is of a bright color, varying from a beautiful red to a brown or yellow, which fades on exposure to light—the color will assist much in judging the quality of the article. The active principle is termed Capsicin. It may be obtained by freeing the fruit from the seeds, submitting it to the action of alcohol, and evaporating the filtered tincture. During the evaporation a red-colored wax separates, and the residuary liquor by further evaporation affords an extract, to which sulphuric ether is to be added. This dissolves the capsicin, which may be obtained by evaporating the ether. It is a yellowish-brown, or red- dish-brown oleaginous substance, of an overpowering acrid taste, vola- tilizes at a moderate elevation of temperature, and disengages so acrid a vapor, that half a grain will cause every person in a large room to cough and sneeze violently. It is slightly soluble in water and vinegar, and very soluble in alcohol, ether, oil of turpentine, and the caustic alkalies, which it renders reddish-brown. The other constituents of capsicum are coloring matter, an azotized substance, gum, pectic acid, and saline matters. It is frequently adulterated with sawdust, canthar- ides, and red-lead. This last may be detected by placing a portion of the suspected powder in some dilute nitric acid, allow it to digest, then filter, and if any oxide of lead be present, the addition of a solution of sulphate of soda, will throw down a white precipitate. Properties and Uses.—Capsicum is a pure, powerful stimulant. The infusion is much used in colds, catarrh, hoarseness, etc. In dyspepsia, it stimulates the nerves of the stomach, promotes the secretion of the digestive juices, and assists peristaltic motion. It forms an excellent Capsicum Annuum. 299 addition to quinia in intermittents, where there is a deficiency of gastric susceptibility. It has been also used in spasmodic affections, passive hemorrhages, especially uterine, and when combined with the compound powder of ipecacuanha, will, in many instances, arrest hemorrhage after parturition, promptly. It has been used successfully in Asiatic Cholera. A preparation made by adding one ounce of powdered Capsicum, and two ounces of salt to one quart of vinegar, has been found an excellent anti-emetic, in all cases of vomiting or nausea. To be given in table- spoonful doses, as often as required. It has received the name of Anti- emetic drops. Capsicum may be used wherever a pure stimulant is indi- cated, in all cases of diminished vital action, and may be combined bene- ficially with other remedies, in order to promote their action, as emetics, cathartics, diaphoretics, tonics, etc. Dose of the powder, from one to six grains; of the tincture, from half to one drachm. Externally, the infusion and tincture have been found valuable as a stimulant gargle in the ulcerated throat of scarlatina, or in chronic cynanche tonsillaris ; also as a counter-irritant, as an application to indo- lent ulcers, and in chronic ophthalmia. It enters into various tinctures and liniments. The concentrated tincture of capsicum has been highly recommended in the treatment of chilblains and toothache. In the former a piece of sponge or flannel must be saturated with it, and rubbed well over the seat of the chilblain, until a strong tingling and electrical feeling is produced. This application should be continued daily, until the disease is removed ; relief will be experienced on the very first application, and frequently there will be a total removal of the disease after the second or third application. This, however, will depend upon the severity of the case. This medicine possesses an extraordinary power in removing congestion by its action upon the nerves and circula- tion ; if the skin is not broken, it never causes excoriation by rubbing with it. For toothache, place a drop or two of the tincture on cotton, and apply it to the affected part, the relief will be immediate. Tinctura capsici concentrata, is prepared by macerating four ounces of capsicum in twelve ounces of rectified spirit for seven days—then filter. The Ethereal Oil of Capsicum, prepared by the evaporation of a satu- rated ethereal tincture of the pods, is sometimes used as a rubefacient. It is of a brilliant yellowish color, with a peculiar odor and aromatic taste, and filled with crystals of capsicin of curious dendroid forms. Off.

CARBO ANIMALIS. Animal Charcoal. CHARCOAL PREPARED FROM BONES — BONE BLACK, IVORY BLACK. Preparation.—Animal Charcoal is much used in pharmacy and the arts, and is prepared by subjecting bones to a red heat in close vessels. The bones are usually subjected to destructive distillation in iron retorts or cylinders, and when the ammoniacal liquor called Bone Spirit ceases to come over, the residuum is charred bone, or bone-black. In this form it is impure, and although serviceable for many purposes in phar- macy and the arts, yet it will be found unfit for others unless purified. The impurities it contains are phosphate and carbonate of lime, carburet, and siliciuret of iron, and sulphurets of iron and calcium. To purify it, the bone-black in fine powder, is digested in diluted muriatic acid, which dissolves or decomposes all the calcareous compounds as well as sul- phuret of iron, with the disengagement of much carbonic acid and some sulphureted-hydrogen. The residuum is then thoroughly washed with boiling water, and contains only charcoal with a small proportion of car- buret and silica. The charcoal is now thoroughly dried, at first by a moderate heat, and then at a low red-heat; because its decolorizing power which was destroyed in the previous steps of its purification, is only restored after the action of a pretty strong heat. History.—Animal Charcoal is a tasteless, insoluble, rather coarse powder, of a dark-brownish-black color. It somewhat resembles vege- table charcoal, but is more dense, and less combustible. Upon long exposure to the atmosphere it absorbs moisture, and loses its decolorizing properties, for which it is chiefly employed. Its decolorizing power is said to depend upon a peculiar aggregation of its particles, induced by the presence of phosphate of lime. It not only removes the coloring principle of vegetable infusions and tinctures, but is likewise capable of taking up their bitter principles, and when purified, takes iodine from solutions containing it, takes numerous salts from their aqueous solutions, and converts chromate of potassa into the carbonate. Properties and Uses.—It is principally used in pharmacy for decolor- izing vegetable principles, as quinia, morphia, etc. ; also for clarifying syrups, and for depriving spirits derived from grain of a peculiar volatile oil, called Grain oil. It has likewise been highly extolled as an internal remedy, in doses of half a grain to three grains, twice a day, in scrofu- lous and cancerous affections, goitre, obstinate chronic glandular indura- tions, etc. Not used in this country medicinally. Like vegetable char- coal, it destroys the odor of putrid animal matter. Dr. A. B. Garrod in a paper read before the Medical Society of London, Nov. 17th, 184G, Carbo Ligni. 301 recommends purified animal charcoal in cases of poisoning by opium, strychnia, aconite, belladonna, stramonium, tobacco, hemlock, arsenic, etc. First remove as much of the poison as possible by means of the stomach pump, or emetics combined with the antidote, and then give a large quantity of the animal charcoal diffused in warm water; a vegetable emetic must not be used as the charcoal would destroy its emetic pro- perty. He considers this agent equal, if not superior to the hydrated sesquioxide of iron, as an antidote to arsenious acid. CARBO LIGNI. Charcoal. Preparation.—Wood, or vegetable charcoal for pharmaceutical or other purposes is made by piling billets of wood in a conical form, and then covering them with earth and sod in such a way as to exclude the access of atmospheric air; several holes must be left at the bottom, and one at the top of the pile, in order to produce a draught to commence the com- bustion. The wood is to be kindled from the bottom, and when com- bustion has taken place and the whole pile ignited, the holes at the top and bottom are to be closed, leaving only a limited access of air. By this process, the volatile portions of the wood, consisting of oxygen and hydrogen are dissipated, while the carbon remains in the form of char- coal. From 17 to 18 per cent, of charcoal is obtained by this process; but if the wood be charred in iron cylinders, from 22 to 24 per cent, of charcoal is obtained, beside the collection of pyroligneous acid, tar, and empyreumatic oil, the volatile products of the wood. For medical purposes, charcoal thus prepared is not sufficiently pure for exhibition, as all the volatile portions of the wood, are not wholly removed. It may be purified, according to Lowitz, by filling a crucible with ordinary charcoal finely pulverized, and luting on a perforated cover. Then expose the whole to a red heat, and continue it as long as a blue flame issues from the aperture in the cover. When this ceases, allow the charcoal to cool, and transfer it quickly to bottles which must be well stopped. History.—Wood charcoal is a dark-brownish-black powder, composed of shining particles, tasteless and inodorous, insoluble in water, and per- manent in the air. It is easily inflammable, and readily consumed, much more so than animal charcoal. It is a good conductor of electri- city, but a bad one of heat. If perfectly dry, it absorbs many times its own bulk of certain gases. It corrects the fetor from putrid animal matters, and decolorizes vegetable infusions, but not so promptly as the animal charcoal. It decomposes metallic compounds when heated with them by depriving them of their oxygen. If exposed to the air, it 302 Materia Medica. increases rapidly in weight, in consequence of its absorption of moisture, which takes place to the amount of from ten to fifteen per cent. Combus- tion disengages its carbonic acid, leaving behind an ash composed of earthy matters and carbonate of potassa. Properties and Uses.—As a medicine, charcoal should always be puri- fied. It is antiseptic and absorbent. Used in dyspepsia attended with fetid breath and putrid eructations; also in dysentery, to correct the fetor of the stools. Useful in acidity of stomach, flatulency, obstinate consti- pation, and in the nausea and constipation attending pregnancy. Dose, from twenty grains to half an ounce, repeated according to indications. Externally, used in poultices to correct fetor of ulcers, arrest gangrene, etc., and is efficient in many cutaneous diseases. It occasionally enters into tooth-powders, and may be used with advantage to correct the fetor of the mouth, and cleanse the teeth. In such cases the charcoal pre- pared from bread is the best, as it contains no gritty particles. Off. Prep.—Cataplasma Carbonis. CARTHAMUS TINCTORIUS. Dyer's Saffron. Nat Ord.—Asteracea3. Sex. Syst.—Syngenesia iEqualis. FLOWERS. Description.—Carthamus Tinctorius, sometimes known as Safflower, Bastard Saffron, etc., is an annual plant, with a smooth stem growing from one to two feet high, striate, and branching at top. The leaves are alternate, ovate-lanceolate, sessile, spinose-denticulate, subamplexicaul, smooth and shining. The flowers are compound, in large, terminal solitary heads. The florets are of an orange-red color, witii a funnel- shaped corolla, of which the tube is long, slender, cylindrical, and the border divided into five equal, lanceolate, narrow segments. History.—This plant is a native of the Levant and Egypt, and is cul- tivated in many parts of Europe and America. The florets are the officinal part. They are generally met with in flaky masses of a red color, intermixed with the yellow filaments; their odor is peculiar and aromatic, and the taste slightly bitter. The cultivated safflower in this country, is usually sold impressed, as American Saffron. They contain two coloring matters—one of which is yellow and soluble in water; the other is red, insoluble in water, slightly soluble in alcohol, and very soluble in alkaline solutions, and is called Carthamine or Carthamic Acid; it is this latter which renders safflower valuable as a dye, especially of silk, and when mixed with finely-powdered talc it forms a rouge. Safflower Carum Carui. 303 is often used to adulterate saffron, but may be detected by its tubular form, and the yellowish color of the style and filaments. Properties and Uses. — Emmenagogue, laxative in large doses, and diaphoretic. Used as a diaphoretic among children in warm infusion, and as a substitute for saffron, in colds, measles, scarlatina, and other exanthematous diseases. To be taken tolerably freely. The infusion may be made by adding two drachms of the flowers to a pint of boiling water. The seeds are white and angular, and have been much used as purgative and emmenagogue. They yield an oil by expression, which has been used as a local application in rheumatic and paralytic affec- tions, also for bad ulcers. CARUM CARUI. Caraway. Ned. Ord.—Apiaceaa or Umbellifera. Sex. Syst.—Pentandria Digynia. SEEDS, (HALF FRUITS). Description. — Carum Carui is an umbelliferous, biennial plant, with a fusiform, whitish, fleshy root, and an erect stem, about two feet high, furrowed, and branched above. The lower leaves are of a bright-green color, petiolate, smooth, bipinnate, with numerous finely-cut leaflets, the segments of which are narrow, linear, and pointed; those of the stem are smaller, opposite, one of them with a dilated petiole, the other ses- sile. The fiowers are numerous, small, of a pale flesh-color, and termi- nate the branches of the stem in erect umbels, which are generally without an involucre, but are sometimes furnished with one to three involucral leaflets. The calyx is very small; the petals are five, small and inflexed; the stamens are about as long as the petals, and bear small, roundish, two-lobed anthers; the ovary is ovate, and supports styles which are at first very short, but become elongated. The meri- carps are elliptic-ovate, of a grayish-brown color, and are marked with single vittae. History.—Caraway is a native of Europe, and has been introduced into this country. It flowers in May and June, and the seeds, which are the officinal portions, are not perfected until the second year, when they become ripe in August. They are obtained by cutting down the plant, and threshing it on a cloth. They are of a brownish color, with five lighter-colored primary ridges, and a vitta in each interval, are about two lines in length, and slightly curved inward. The odor is pleasantly aromatic, and the taste warm, sweetish, and spicy; which properties depend upon a volatile oil, which is officinal, and which may be obtained by distillation. The oil is at first pale, becomes darker by 304 Materia Medica. age, and has the peculiar fragrance and taste of the seed. The virtues of the seed are readily yielded to alcohol or ether. Properties and Uses.—Aromatic carminative. Used in flatulent colic, especially of children, and as an adjuvant or corrective of other medi- cines. In substance the dose is from ten to sixty grains. The oil, however, is mostly employed. (See Oleum Carui.) The seeds are much used by the cook and confectioner to improve the flavor of cakes and comfits, while at the same time they gently stimulate the digestive organs. Off. Prep.— Oleum Carui; Tinct.

Description. — Caryophyllus Aromaticus is an elegant tree, rising to the hight of fifteen or twenty feet; it is of a conical or pyramidal form, is always green, and the whole plant is glabrous. The branches are numerous, slender, opposite, and more or less virgate. The stem is of hard wood, and covered with a smooth, grayish bark. The leaves are about four inches in length by two in breadth, opposite and decussate, persistent, somewhat coriaceous and shining, with a strong midrib and parallel lateral nerves; ovate-lanceolate, entire, smooth on both sides, with numerous pellucid dots, of a green color, paler beneath, and taper- ing gradually at the base into a slender footstalk about two inches in length. The flowers exhale a strong, penetrating, agreeable odor, and are in short terminal cymes, trichotomously divided, and jointed at every division. The calyx is superior, and consists of a cylindrical tube, and four ovate, concave, spreading segments; it is first green, but sub- sequently red, coriaceous. The petals are four, ovate, concave, yellow- ish-red, larger than the calyx, coherent by their edges, and forming a calyptra which is caducous. In the center of the calvx, and at the top of the ovary, is a quadrangular, elevated line or gland, surrounding, but not embracing the base of the shortish, obtusely-subulate style; around this line, immediately within the petals, the stamens are inserted; these are longer than the petals, and bear small, yellow, ovate-cordate, two-celled anthers. The ovary is oblong, almost cylindrical, two-celled, and many small ovules in each cell. The berry is purplish, elliptical, one or two-seeded. Seed covered with a soft, thin, integument. History.—A tall and beautiful tree, growing in tropical climates. The flowers are collected in October and November, before they are fully Cassia Fistula. 305 developed, and consist of a tubular calyx, bearing a roundish bud of unexpanded petals; they are quickly dried in the shade to prevent the escape of volatile oil. The finest kinds are plump, heavy, and dark, and give out oil when squeezed with the nail. They are from five to ten lines long, and from one to one and a half thick, dark-brown exter- nally, yellowish-red internally, of a strong, fragrant odor, and of a hot, pungent, aromatic, permanent taste. Cloves contain volatile oil, fixed oil, a peculiar tannin, gum, resin, fiber, water, and two crystalline prin- ciples called Caryophyllin and Eugenin. They impart their sensible properties to alcohol, spirit, and ether; water extracts only the odor. The active properties reside in the volatile oil, which is of a pale reddish- brown color, darkens by age, and is heavier than water; it is extremely pungent and acrid. Properties and Uses. — Aromatic, stimulant, and irritant. Used to relieve nausea, or vomiting, flatulency, and to excite languid digestion: chiefly employed to assist or modify the action of other remedies, and prevent a tendency to their producing sickness orgriping.

Purging Cassia. Nat. Ord-—Fabaceae, or Leguminosas. Sex. Syst.—Decandria Monogynia. FRUIT, OR PULP OF THE PODS. Description.—Cassia Fistula is a large tree growing from twenty to forty feet high, with a trunk of hard, heavy wood, dividing toward the top into numerous spreading branches, and covered with a smooth, ash- colored bark. The leaves are pinnate, alternate, from twelve to eighteen inches long, deciduous. The leaflets are opposite or nearly so, from four to eight pairs, ovate, pointed, smooth, undulated, of a pale-green color, polished on both sides, on short, round petioles, from two to six inches long, and from one and a half to three broad. The flowers are large, fragrant, bright-yellow, on long, slender, smooth pedicels. Racemes axillary, pendulous, simple, one or two feet long. The calyx has five nearly equal, oblong, obtuse, smooth sepals. The corolla consists of five petals, which are oval, unequal, concave, spreading, and waved. The three lower filaments much longer than the others, and having a double curve, but no swelling. Anthers on the three long filaments 306 Materia Medica. oblong, opening by two lines on the face, the other seven clavate, with pores at the small end. Ovary filiform, smooth, cylindrical, curved, one- celled, containing numerous seeds. The fruit is a woody, dark-blackish- brown, cylindrical pod or legume, a foot or more in length, and about an inch in diameter, with two longitudinal furrows on one side, and one on the other, divided into numerous cells by thin transverse diaphragms, each containing a single, oval, smooth, shining, somewhat compressed seed, imbedded in a viscid, black, sweetish pulp. History.—Purging Cassia is a native of Upper Egypt and the East Indies, from whence it is supposed to have been transplanted to other parts of the world. It is found in India, Cochin-China, West Indies, and South America. The fruit is the officinal portion. Those pods are to be selected which are the heaviest, and do not rattle when shaken, as they contain the most pulp, which is the part used. To obtain it, the pods are first bruised, and boiling water is poured on them so as to wash out the pulp ; the decoction is then strained, and evaporated to the proper consistence. The pulp has a faint, nauseous odor, and a sweet, mucila- ginous taste; it contains sugar, gum, a substance resembling tannin, a glutinous principle, and a coloring matter soluble in ether, with a small portion of water. When good it should be black and shining; if kept in a damp place it becomes moldy, and long exposure causes it to turn sour. It keeps longest when preserved in the pod. It is nearly soluble in water, and its active parts are taken up by alcohol. Properties and Uses.—A mild and effectual laxative, useful in habitual constipation. If administered in large doses it purges, occasioning also nausea, flatulence, and griping. Dose as a laxative, one or two drachms, as a purgative one or two ounces. It is seldom employed except as an ingredient in the confection of senna. CASSIA MARILANDICA. American Senna. Nat. Ord.—Fabaceas. Sex. Syst.—Decandria Monogynia. LEAVES. Description. — Cassia Marilandica is an indigenous, perennial plant, growing from four to six feet high, with round, striated, smooth, or slightly hairy stems. The leaves are alternate, rather long, not numer- ous, and composed of from six to nine pairs of ovate, lanceolate, smooth, entire leaflets, green above, and yellowish-green beneath; the common petiole is furnished at the base with a large ovate, stipitate, shining-green gland, terminating in a dark point at the top, which is Cassia Acutifolia. 307 sometimes double. The flowers are bright yellow, in axillary racemes, on furrowed peduncles ; the pedicels are long, glandular, and bracteate. The petals are five, concave, very obtuse and unequal, the two lower being the largest. The stamens are ten, with yellow filaments, and brown anthers, which open by a terminal pore. The three upper sta- mens bear short abortive anthers ; the three lowermost are long, curved, and tapering into a beak. The fruit or legume is pendulous, from two to four inches long, narrow, arcuated, mucronate, blackish, with a few scattered, reddish hairs, and containing many seeds. History.—This plant is common to most parts of the United States, in low, moist situations, and flowering from June to the latter part of August, about which time the leaves should be collected, or in the beginning of September. Water or alcohol extracts their virtues. The leaves have a faint odor, and a nauseous taste not unlike that of the foreign senna, to which drug it is not inferior in medicinal activity. They are usually had in compressed packages from the Shakers, who cultivate the plant. Mr. Martin of Philadelphia, found the leaves to contain albumen, mucilage, starch, chlorophylle, yellow coloring matter, volatile oil, fatty matter, resin, lignin, salts of potassa and lime, and a principle analogous to cathartin. The Cassia Chamcecrista, Prairie Senna or Partridge Pea, growing on the western prairies, is an excellent substitute for the above ; it is like- wise known as Dwarf Cassia and Sensitive Pea. Properties and Uses. — A safe and efficient cathartic, equal to the imported article, for which it may be substituted. But, owing to the presence of argel leaves, the foreign senna has its activity increased, hence, in giving the American article, the dose will be one-third larger than of the other. Its most convenient form of administration is that of infusion, which should be combined with articles similar to the infu- sion of imported senna, in order to obviate any tendency to griping. The dose in powder is from half a drachm to two and a half drachms. The infusion may be made by adding one ounce of the leaves, with a drachm of coriander seeds, to a pint of boiling water. Macerate for an hour in a covered vessel, and strain ; dose, four or five fluidounces. CASSIA ACUTIFOLIA. Senna. Nat. Ord.—Fabaceas. Sex. Syst.—Decandria Monogynia. the leaves. Description.—There are several species of Cassia plant, which are supposed to yield the Senna, as the C. Acutifolia, C. Obovata, C. Elon- 308 Materia Medica. gata, C. Lanceolata, etc. Cassia Acutifolia is a perennial shrub, growing from two to ten feet high, with an erect, woody, smooth, branching, whitish stem. The leaves are alternate and pinnate, with glandless foot- stalks, and two small, narrow, pointed stipules at the base. The leaflets from four to eight pairs to each leaf, are nearly sessile, oval-lanceolate, acute, oblique at their base, nerved, from half an inch to an inch long, and of a yellowish-green color. The flowers are brigmt yellow, and in axillary spikes. The ovary is linear, downy, falcate, with a smooth, recurved style. The fruit or legume is pendulous, flat, elliptical, obtuse, membranous, smooth, grayish-brown, bivalved; quite straight, about an inch long, and half an inch broad, and divided into six or seven cells each containing a hard, heart-shaped, ash-colored seed. It grows in great abundance in Upper Egypt, and furnishes the greater part of the Alexandria Senna of commerce. Cassia Obovata, a perennial, is smaller than the above, growing to the hight of about eighteen inches ; with a stem pubescent at the base, and cylindrical. The leaves are alternate, equally pinnate, smooth, with two subulate, entire, persistent stipules at the base, and with from four to seven pairs of opposite, nearly sessile, obovate, cuneiform leaflets, obtuse but mucronate at the apex, unequal at the base ; the uppermost gradu- ally the largest, slightly pubescent. The flowers are pale-yellow, and in erect, rather loose axillary racemes. The legumes oblong, falcate, mem- branous, smooth, rounded at each end, with an elevated, interrupted ridge along the middle. The seeds are from six to eight, and heart- shaped. This species grows wild in Egypt, Nubia, Syria, and Sene- gambia ; and has been cultivated in the West Indies, and many parts of southern Europe. It is very nearly identical with the C. Obtusata of Heyne. This plant furnishes an inferior senna, known as the Italian or Aleppo Senna. Cassia Elongata, is an annual, but with care it may be made to live through the year, and to assume a suffruticose character. It has a smooth, erect stem, and narrow, equally pinnated leaves with from four to eight pairs of lanceolate leaflets, which are nearly sessile, slightly mucro- nate, smooth above, rather downy beneath, oblique at the base, with the veins turned inward so as to form a wavy line immediately within the margin of the leaflet; petioles glandless ; stipules softly spinescent, semi- hastate, spreading, minute. The flowers are bright yellow, and arranged on erect, stalked, axillary and terminal racemes, rather longer, than the leaves. The legume is pendulous, oblong, membranous, tapering abruptly at the base, rounded at the apex, an inch and a half long, and about half an inch broad, with many deep-brown seeds. It is supposed to grow in southern Arabia, and in the interior of India, and is cultivated at Tinnivelly. Cassia Acutifolia. 309 Cassia Lanceolata resembles the above, having, however, never more than four or five pairs of leaflets, oblong, and either acute or obtuse, not at all ovate or lanceolate, and perfectly free from downiness even when youno-; the petioles have constantly a small, round, brown gland a little above the base. The pods are erect, oblong, tapering to the base, obtuse, tun-id, mucronate, rather falcate, especially when young, at which time they are sparingly covered with coarse, scattered hairs. It grows in Arabia, and was considered by Forskhal as the true Mecca Senna. History.—These are supposed to be the principal species which yield the Senna, though much uncertainty exists with regard to them, arising from the want of correct specimens, the difficulty attending the investi- gation of the plants in their places of growth, the ignorance of the influ- ences which a change of locality may exert upon them, and whether the presence or absence of the glands on the petioles are to be assumed as specific characters. Although this confusion exists in the botanical his- tory of senna, yet, in commerce, but three varieties of the drug are found, or which are ever imported into this country, these are, the Alex- andrian or Egyptian, which is the finest and most valuable article, the Indian, and the Tripoli Senna,. Alexandria Senna is collected from Sennaar, Nubia, and Upper Egypt, and made up at Boulak, not far from Cairo, under the superin- tendence of the Egyptian government, from which place it is forwarded to Alexandria, for the European markets. It consists of the leaflets of C. Acutifolia, C. Obovata, pods, broken leafstalks, flowers, etc., likewise the leaves of Cynanchum Oleafolium, or Solenostemma argel. The harvest for collecting commences in September, at which time the branches of the shrub are cut, and exposed to the sun, until the leaves begin to fade; they are then collected into bundles, and placed on rocks and high grounds, in order to have full benefit of the air and of the sun's rays. When the leaves are quite dry, the branches are threshed, and the leaves separated from them, they are then packed in sacks and sent to Boulak, at which place their adulteration with other leaves is said to take place. As received in this country, Alexandria Senna is generally in bales and barrels, and is considered the finest and most valuable variety ; the best and most esteemed is that which contains the least quantity of cy- nanchum leaves, senna leafstalks and pods, where the entire lanceolate leaves are numerous, and where the odor and taste is strong and pure. It has a peculiar but not disagreeable odor, with an unpleasant, nauseous, mucilaginous, and sweetish taste, with hardly any perceptible bitterness, unless it be adulterated with the leaves of the Argel or Cynanchum olece- folium which impart bitterness to the powder or infusion, and which is the most important impurity to remove. They may be recognized by having no visible lateral nerves on their under-surface ; by being longer, thicker and firmer than senna leaves; by the greater regularity of their 310 Materia Medica. base, being of a lighter color, of a bitter taste, and often spotted with a yellow, bitter, gummy-resinous incrustation. Tripoli Senna somewhat resembles the Alexandrian, but is considered much inferior to it; the leaves are more broken down, and the leafstalks more numerous. It seems to consist of one of the acute leaved species and a slight admixture of C. Obovata, and very seldom contains any adulteration with the argel leaves. T|^re is much uncertainty as to the place from which it is derived. India or Mocha Senna is of three kinds, the Bombay, the Madras, and the Tinnivelly, of which the first, is usually imported from Bombay, though it comes in the first instance from Mocha and other ports of the Red Sea; the second and third from Madras; of these, the Tinnivelly is esteemed the best. India Senna consists mainly of large, thin, unbroken, acute, yellowish-green leaves, seldom adulterated, and when good, is fully equal to the Alexandrian. There are other varieties, but they sel- dom reach this market. Good Senna may be known by the bright, fresh, yellowish-green color of the leaves, with a faint and sickly odor somewhat similar to green lea, and a nauseous, mucilaginous, sweetish, and slightly bitter taste; and the fewer the stalks, seed pods, broken leaves, and dirt, the better is the senna. Its active principles are taken up by cold or warm water, alco- hol, and proof spirits ; boiling destroys its virtues unless it be in vacuo, or in a covered vessel. Various analyses have been made of senna, but there are none on which we can satisfactorily rely. M. M. Lassaigne and Feneulle found it to contain a peculiar bitter principle called Cathar- tin, chlorophylle, fixed oil, a small quantity of volatile oil, albumen, yel- low coloring matter, mucilage, malate and tartrate of lime, and acetate of potassa, and some mineral salts. The cathartin is a yellowish-red, uncrystallizable substance, of a peculiar odor, and a bitter, nauseous taste, very soluble in water and alcohol, but insoluble in ether. It is considered to be the purgative principle of the drug, yet this is not uni- versally admitted, as several experimenters deny that it possesses any purgative power whatever. The infusion or decoction of senna is incom- patible with strong acids, alkaline carbonates, lime-water, tartar emetic, acetate of lead and tannin, or astringent plants containing tannin. The tartarized antimony and acetate of lead do not precipitate the cathartin. Properties and Uses.—Senna is r. certain, manageable, and convenient cathartic, very useful in all forms of febrile disease, and other diseases where a violent impression on the bowels is not desired. Its influence is chiefly exerted on the small intestines, augmenting their mucous secre- tions, exciting increased peristaltic motion, and producing loose brown evacuations. It does not act as a sedative, as is the case with some cathartics, nor as a refrigerant; but has a slight stimulating influence, insufficient however, to contra-indicate its use in cases of general excite- Castoreum. 311 ment, or reaction. Beside the nauseating taste of senna, it is apt to cause sickness at stomach, and very few persons can use it alone, with- out experiencing more or less griping pains. The addition of cloves, ginger, cinnamon, or other aromatics are excellent correctives of these unpleasant effects. A teaspoonful of cream of tartar to a teacupful of the decoction or infusion of senna, is a mild and pleasant cathartic, par- ticularly suited for females where it may be required soon after delivery. The addition of neutral laxative salts is another mode, adopted by a cer- tain class of practitioners, of preventing the tormina, and at the same time of increasing the activity of the infusion of senna, as, phosphate of soda, Epsom, or Rochelle salts; these are, however, rarely used by Eclectics. Saccharine and aromatic substances are also sometimes com- bined for this purpose, as sugar, manna, aromatic seeds, electuary of senna, etc. The purgative effect of senna is much increased by the addition of the pure bitters; the decoction of guaiacum is said to answer a similar purpose. Senna is contra-indicated in an inflammatory condi- tion of the alimentary canal, hemorrhoids, prolapsus ani, etc. The dose in powder is from thirty to fifty grains; in tincture, from half a fluidounce to two fluidounces ; electuary, two drachms; and of the infusion, which is the most usual mode of administration, from two to four fluidounces. A preparation termed Cassine, said to be the active principle of the Alexandria Senna, is advertised as a preparation of an eastern manufac- turing establishment. It is stated to be a whitish-brown powder, of a slightly bitter taste, a senna-like odor, soluble in water and insoluble in alcohol. I have not seen it, nor have I been able to obtain its mode of preparation. Off.

CASTOREUM. Castor. History.—This drug is a peculiar concrete substance obtained from the preputial follicles of the Castor Fiber, or Beaver. These follicles are filled with a thick fluid secretion, which slowly concretes when they are removed from the animal. Most of the castor of the present day is derived from the beaver of North America. It has much the appear- ance of a pair of dried testicles united by their spermatic chords, dark liver brown and wrinkled externally, paler liver brown internally, resinous in fracture, when perfectly dried of a strong, peculiar heavy odor, and of an aromatic, bitter, offensive taste. Rectified spirit is its best solvent; though ether extracts a good part of its virtues. 312 Materia Medica. The Russian castor, from the Russian dominions, is seldom seen in this country; it may be distinguished from the American by being larger, fuller, heavier, and less tenacious, and by its stronger taste and smell. Treated with distilled water and ammonia, M. Kohli states that it affords a white precipitate, while the American throws down an orange-colored matter. Good castor has a strong, fetid, peculiar odor ; a bitter, acrid, and nauseous taste, and a color more or less tinged with red. It is composed of numerous salts, mucus, a volatile oil, a resinous substance, a horny matter, osmazome, and a peculiar crystalline, non-saponifiable principle called castorin. Age impairs the virtues of castor, which is hastened in an elevated temperature ; moisture promotes its rapid decom- position. It should always be kept in a dry cool place. It is not good if quite black, tasteless and inodorous. A factitious preparation is often sold, consisting of a mixture of various drugs, scented with genuine castor, intermixed with membrane, and stuffed into the scrotum of a goat. The feeble odor, want of other characteristic sensible properties, and the want of the smaller follicles containing fatty matter, and which are always attached to the genuine bags of castor, will enable one to detect the fraud. Properties and Uses. — Moderately stimulant, antispasmodic, and emmenagogue. Used in hysteria, amenorrhea, epilepsy, and many anomalous nervous affections. Dose of the substance, from ten to twenty grains ; of the tincture, from half a fluidrachm to two fluidrachms. Off. Prep.—Tinctura Castorei; Tinctura Castorei Ammoniata. CAULOPHYLLUM THALICTROIDES. (Leontice Thalictroides.) Blue Cohosh. Nat. Ord-—Berberidaceas. Sex. Syst.—Hexandria Monogynia. ROOT. Description.—This plant, likewise known as Squaw root, Pappoose root, is a smooth, glaucous plant, purple when young, with a high, round stem from one to three feet in hight, simple from knotted and matted rootstocks, and dividing above into two parts, one of which is a tri- ternate leaf-stalk, the other bears a biternate leaf and a racemose pani- cle of small yellowish-green flowers. The leaves are biternate and triternate ; petiole trifid, and supporting nine leaflets. Leaflets oval, petiolate, unequally lobed, the terminal one equally three-lobed, paler beneath, and from two to three inches long. The flowers appear in May and June. Panicle small, shorter than the leaves. Pericarp thin, cadu- cous, dark-blue, resembling berries on thick stipes. Seeds one or two, erect, globose, about the size of a large pea. Caulophyllin. 313 History.—A handsome perennial plant growing all over the United States, in low, moist, rich grounds, near running streams, in swamps, and on islands that have been overflowed with water. The seeds ripen in the latter part of the summer, and are said to form an excellent sub- stitute for coffee, when roasted. The fruit is dry, sweetish, insipid, and resembles that of the Vaccinium. The officinal part is the root, which is sweetish, somewhat pungent and aromatic, and affords a yellow infu- sion or tincture. No chemical analysis of the root has been made, though it affords a resinous principle, to which I have given the name of Caulophyllin. Properties and Uses.—This is essentially an agent peculiar to Eclec- tics not being employed by any other class of practitioners. It is principally used as an emmenagogue, parturient, and antispasmodic ; but it likewise possesses diuretic, diaphoretic, and anthelmintic proper- ties. It has been successfully employed in rheumatism, dropsy, colic, cramps, hiccough, epilepsy, hysteria, uterine inflammation, etc. It is a valuable agent in all chronic uterine diseases, appearing to exert an especial influence upon the uterus, and has been found serviceable in uterine leucorrhea, amenorrhea, dysmenorrhea, etc. When used in decoction for several weeks previous to the parturient period, it is said to facilitate that process, acting as a preparatory parturient, and it is sometimes combined with the Mitchella Repens, and Eupatoria Aroma- tica, for this purpose. Combined with equal parts of powdered Hydras- tis Can., made into an infusion, and sweetened with honey, it forms an elegant and effectual wash for aphthous sore-mouth and throat. In decoction, blue cohosh is preferable to ergot for expediting delivery, in all those cases where the delay is owing to debility, or want of uterine nervous energy, or is the result of fatigue. The decoction or infusion may be made by adding an ounce of the root to a tint of boiling water, and boiling or macerating for a short time ; the dose of either is from two to four fluidounces, three or four times daily. The tincture should be made by adding three ounces of the finely powdered root to a pint of alcohol, and allow it to macerate for fourteen days ; then filter. The dose is from half a fluidrachm to two fluidrachms. Off. Prep.—Caulophyllin ; Extractum Caulophylli Hydro-alcoholi- cum ; Tinctura Caulophylli Composita. CAULOPHYLLIN. THE ACTIVE PRINCIPLE OF THE ROOT OF CAULOPHYLLUM THALICTROTDES.' Preparation.—Caulophyllin is the name I have given to the active principle of the root of Caulophyllum Thalictroides. It is an Eclectic remedy, not known or used by any, other class'of practitioners, and was 314 Materia Medica. first manufactured by W. S. Merrell of Cincinnati. He prepares it by precipitation from the saturated tincture, similar to the preparation of cimicifugin, using, however, as small a quantity of water as possible to prevent waste, as the precipitate is soluble in water. Chemical Properties.—Caulophyllin thus prepared is a resinous sub- stance of a light-brown color, with a peculiar, not unpleasant odor, somewhat similar to podophyllin, and leptandrin, and a slightly bitter taste with some degree of pungency. Its chemical reactions have not been thoroughly investigated; it appears, however, to be a neutral sub- stance, like salicin, exhibiting neither acid nor alkaline principles. It is insoluble in ether. In water it is partially soluble, in alcohol more so; the addition of aqua ammonia renders it completely soluble in either menstruum, and the solution becomes of a dark-reddish wine color. Its aqueous solution is also rendered perfect by the addition of liquor potassa, nitric, or muriatic acids. Acetic acid does not solve it. The N. Y. Journal of Organic and Medical Chemistry, vol. i, p. 12, states that Caulophyllin may be obtained by treating the root of Cau- lophyllum with distilled water, and obtaining an aqueous solution by percolation. This solution is to be decolorized by animal charcoal, then evaporated in vacuo, and precipitated with an infusion of nutgalls, or, what is still better, 96 per cent, alcohol. A white precipitate is obtained, which can be dried on filter-cloth and powdered. The properties of the caulophyllin thus obtained, are similar to those detailed above, being soluble in water, partly so in alcohol, and possessing similar therapeutic influences ; yet, it is there termed an alkaloid. It is to be regretted that in our eagerness to discover concentrated medicinal principles and their therapeutic advantages, but little attention is bestowed upon their chemical relations. Properties and Uses.—Caulophyllin appears to exert a direct influence upon the uterus, acting as an alterative, uterine tonic, and parturient, according to the periods in which it is employed. In the more common unhealthy conditions of this organ and its appendages, known as amen- orrhea, dysmenorrhea, passive menorrhagia, leucorrhea, congested cer- vix, etc., it is equal to, if not surpassing the cimicifugin. A combina- tion of equal parts of caulophyllin, cimicifugin, and carbonate of ammo- nia, will be found especially valuable not only in the above-named affections but likewise in epilepsy, hysteria, rheumatism and dropsy, in which diseases it has been recommended as an antispasmodic. It may also be advantageously combined with aletrin, asclepidin, senecin, etc., in many forms of disease of the female generative organs. It has been spoken of as a parturient, but we have no knowledge of its influence as such—though we are aware that the root from which it is prepared does exert a parturient effect; which property, if retained by the caulo- phyllin will no doubt render it valuable to the accoucheur. Added to Ceanothus Americanus. 315 podophyllin or other active purgatives, it prevents tormina, and is, probably, the best agent that can be employed for this purpose. Dr. T. J. Kindlebergcr of Springfield, 0., writes that he has used it with much advantage in after-pains, in menstrual suppression, and in dysmenorrhea. He closes his letter, by observing, " In my opinion it far surpasses ergot, both in its acting more mildly, and with more certain results. It will, no doubt, occupy a very elevated position among remedial agents, when it becomes fully known to the profession." The ordinary dose of the article is from one-fourth of a grain to one grain, two, three, or four times a day. As a parturient it should be given in doses of from two to four grains, and repeated at intervals of from fifteen to thirty or sixty minutes, after actual labor has commenced. In one case, reported, where labor had lasted five days, the patient much enfeebled, and the labor complicated with artificial pains, caulophyllin was given in two grain doses every half hour ; but three doses were given, labor having,- commenced soon after the second was taken, and terminated successfully in one hour and forty minutes from the time the first powder was given. Caulophyllin may be advantageously combined with dioscorein in bilious colic and flatulence. With podophyllin and muriate of ammonia, it forms an excellent combination for some nephritic diseases, accompanied with pains of a spasmodic character. CEANOTHUS AMERICANUS. Redroot. Nat. Ord.—Rhamnaceas. Sex. Syst.—Pentandria Monogynia. BARK OF THE ROOT. Description.—This plant, likewise called New Jersey Tea, Wild Snow- ball, has a large root, with a red or brown epidermis, containing many small white veins, and tolerably thick; body of the root dark-red. The stems are from two to four feet high, slender, suffruticose, with many reddish, round, smooth branches, the younger of which are pubescent. The leaves are ovate or oblong-ovate, somewhat acuminate at the apex, rounded, or slightly cordate at the base, serrated, three-nerved, nearly smooth above, and whitish, tomentose beneath, the pubescence of the veins and petioles somewhat reddish. The flowers are white, in long, crowded panicles from the axils of the upper leaves. Calyx white, five- cleft, and the upper portion separates by a transverse line, leaving the tube adhering to the fruit. The corolla is formed of five-saccate, arched petals, which are longer than the calyx, and with filiform claws at base. The stamens are five, exserted, and bearing ovate, two-celled anthers. The ovary is three-angled, and surrounded with a ten-toothed disk. 316 Materia Medica. The styles are three, united to the middle, but diverging above. The fruit is dry and coriaceous, obtusely triangular, three-celled and three- seeded. The seeds are convex externally, concave internally, the cavity marked with a longitudinal line. History.—C. Americanus is found in all parts of the United States, in copses and dry woods, and flowering from June until September. The leaves, when dried, have an odor and taste resembling black tea, and were used durino- the revolutionary war as a substitute for the Chinese tea ; they are slightly bitter and astringent. The root is the officinal part, and has a taste and smell somewhat resembling those of the peach leaf. It has been occasionally used for coloring. Water extracts its active principle. The leaves are said to contain tannin, a soft resin, a bitter extractive, a greenish coloring matter almost identical in color and taste with green tea, gum, a volatile substance, lignin, and an active principle called Ceanothine. This principle, as stated in the New York Journal of Organic and Medical Chemistry, vol. 1, p. 43, is obtained by first removing the resin- ous extractive, and most of the coloring matter from the leaves, by treating them with alcohol. The mass is then placed in an alembic apparatus, and the alcohol remaining in the leaves displaced, after which the mass is submitted to the percolating process with hot distilled water, until the active principle is displaced. The aqueous solution is then evaporated in vacuo to the consistency of thick syrup, and precipitated and purified in alcohol nearly absolute. The precipitate is then placed in vacuo at a temperature of about 100° F. By this means the alcohol remaining in the precipitate is gradually removed, and the Ceanothine remains in a dried mass partially in the form of crystals, after which it is reduced to a fine powder. When purified it is white; its odor and taste is similar to that of green tea; it is soluble in water, but insoluble in alcohol. Properties and Uses. — Astringent, expectorant, sedative, antispas- modic, and antisyphilitic. Used in gonorrhea, dysentery, asthma, chronic bronchitis, hooping-cough, and other pulmonary affections. Dose of a strong decoction, one tablespoonful three or four times a day. It has likewise been successfully used as awash and gargle in the aphthae of children, sore mouth subsequent to fever, and in ulceration of the fauces attendant on scarlatina. Off.

Description.—This plant, likewise known by various other names, as Staff-vine, Waxwork, Climbing Bittersweet, Climbing Staff-tree, etc., is a climbing, indigenous shrub, with a woody, twining stem, without thorns or prickles ; the leaves are thin, oblong, acuminate, serrate, alternate, stipulate, petiolate and smooth ; the racemes are small, terminal, and axil- lary ; the flowers are greenish-white, or yellowish-white, fragrant and dioecious. Calyx flat, five-lobed ; corolla spreading, of five sessile petals; capsule obtusely three-angled, three-celled, berry like; valves bearing the partitions on their centers ; stamens standing around a glandular five- toothed disk; style thick; stigma three-cleft. Seeds covered with a scarlet aril, one or two in each cell. History.—This plant grows in woods and thickets, from Canada to Carolina, creeping on hedges and rocks, or (wining about other trees, or each other, and ascending to a great Light. It flowers in June, and bears a scarlet berry which remains through the winter. The plant thrives most luxuriously in a rich, damp soil. The root is very long, creeping, woody, of a bright orange color, about half an inch in thickness, with a thick, red, or yellowish-red bark, which is the officinal part. On account of the similarity of name, Bittersweet, the plant has been confounded with the Sdunum Dulcamara, from which, however, it essentially differs in appearance and therapeutic action. The bark has a sweetish, rather nauseous taste, and imparts its medicinal properties to water. Properties and Uses. — Alterative, diaphoretic, and diuretic, with some narcotic powers. Used in scrofula, secondary syphilis, chronic hepatic affections, cutaneous affections, leucorrhea, rheumatism, and obstructed menstruation. Externally, an ointment has been successfully employed in inflamed and indurated breasts of nurses. Dose of the decoction, from two to four ounces, three times a day; of the extract, from five to ten grains. Off. Prep.—Decoctum Celastri; Syrupus Rumicis Compositus. CENTAUREA BENEDICTA. Blessed Thistle. Nat. Ord.—Asteraceas. Sex. Syst.—Syngenesia Frustranea. LEAVES. Description. — Centaurea Benedicta, or Cnicus Benediclus of De Candolle, also known as Holy Thistle, is an annual, herbaceous plant, 318 Materia Medica. with a whitish, fibrous, branched, tapering root, with several stems, about two feet high, and which are trailing, roundish, furrowed, reddish, woolly, and branching toward the top. The lower leaves are petiolate, but the upper are sessile, alternate, and somewhat decurrent; the whole are oblong, rough, aculeate, sinuate or almost ruminate, and armed with many sharp spines; of a green color above, and paler and reticulated beneath. The flowers are large, of a bright-yellow color, solitary at the ends of the branches, inclosed by a bracteate involucrum of ten leaves, the five exterior of which are largest. True involucrum ovoid, imbri- cated, smooth, woolly, each scale being terminated by pinnate spines, connected with the bracts by fine threads. Ray-florets small and sterile, those of the disk perfect, tubular, and toothed. Stamens five, downy, with linear-oblong united anthers. The style is filiform with a cleft stigma. The achenia are oblong, brown, striated, on a bristly receptacle. History.—This is a native of the south of Europe, and naturalized in the United States. It flowers in June, when its medicinal virtues are in the greatest perfection. The leaves should be gathered while the plant is in flower, quickly dried, and kept in a dry place. They have a feeble, unpleasant odor, and an intensely bitter taste. Water or alcohol extracts their virtues. The infusion with cold water is a pleasant bitter; the decoction is nauseous and offensive to the stomach. The leaves contain volatile oil, a bitter principle, resin, a fixed oil, gum, sugar, albumen, some salts, etc. The bitter principle is supposed to be the active one of the plant, and is named Cnicin; it is crystallizable, inodorous, very bitter, neutral, hardly soluble in cold water, more so in boiling, and soluble in alcohol. It is analogous to salicin in composition, and consists of carbon, hydrogen, and oxygen. In doses of from four to eight grains it often vomits and has proved useful in intermittent fevers. Properties and Uses. — A cold infusion is tonic ; a warm infusion diaphoretic, and if strong, emetic. Used as a tonic in loss of appetite, dyspepsia, and intermittent diseases. Dose of the powder, from ten to sixty grains ; of the infusion two fluidounces. Off. Prep.—Infusum Centaureae. CEPHAELIS IPECACUANHA. Ipecacuanha. Nat. Ord.—Cinchonaceaa. Sex. Syst.—Pentandria Monogynia. ROOT. Description.—Cephaelis Ipecacuanha is a small shrubby plant, with a perennial root, descending obliquely into the ground, from four to six Cephaelis Ipecacuanha. 319 inches long, about as thick as a goosequill, simple, or divided into a few divergent branches, marked with annular rugae, flexuose, contorted, epidermous, glabrous, of a pale-brown color in the recent root, and umber or blackish-brown in the dry; the cortex is soft, white, and sub- amylaceous in the fresh root, and pale-reddish, or rose-colored in the dried state, of a shining and resinous fracture, and readily separable from a central woody axis. The stem is suffruticose, from two to three feet long, ascending, often rooting near the ground, smooth and cinereous at the base, downy and green near the apex. The leaves are rarely more than four or six on a stem, oblong-ovate, acute, roughish with hairs, from three to four inches long, and from one to two broad; those at the top of the stem are opposite, and those toward the base alternate. Petioles short, downy. Stipules erect, appressed, membran- ous, deciduous, four to six cleft. Peduncles solitary, axillary, downy, erect when in flower, reflexed when in fruit, about one inch and a half long. Flowers small, white, in semiglobose heads, of eight, twelve or more; involucre one-leafed, spreading, deeply four to six-parted, with obovate acuminate, ciliated segments. Bracts to each flower one, obovate-oblong, acute, downy. Calyx minute, obovate ; whitish, adher- ing to the ovary, with five-bluntish, short teeth. Corolla white, funnel- shaped ; tube cylindrical, downy on the outside and at the orifice; limb shorter than the tube, with five ovate reflexed segments. Stamens five; filaments filiform, white, smooth ; anthers linear, longer than the fila- ments, projecting a little beyond the corolla. Ovary with a fleshy disk at the apex; style filiform; stigmas two, linear. Berry ovate, obtuse, about the size of a kidney-bean, at first purple, subsequently violet- black, two-celled, two-seeded, with a longitudinal fleshy partition. Nucules plano-convex, furrowed on the flat side. History.—This is a small, scrubby, perennial plant, found in the moist shady woods of Brazil, and other sections of South America, but mostly between the eighth and twentieth degree of south latitude. It flowers in January and February, and ripens its fruit in May. The root, which is the officinal part, is collected during the flowering season by the Indi- ans, who after plucking it from the ground, separate it from the stem, clean it, and hang it up in small parcels in the sun for the purpose of drying. It is principally imported from Rio Janerio, Bahia, and Pernam- buco, in large bags or bales. As imported into this country, ipecacuanha is in pieces two or three lines in thickness, contorted, simple or branched, tapering from the center toward both ends, irregular rings or rugae, separated by narrow fissures frequently extending nearly down to the central fiber. The internal meditullium or woody part is slender, and light straw-colored ; the cortex or bark is hard, horny, translucent, breaking with a resinous fracture, and easily separating from the central ligneous cord. It is not 320 Materia Medica. very readily pulverized, and is the most active part of the root. Phar- macologists have divided ipecacuanha into three varieties, the grayish- black, the grayish-red, and the grayish-white, which are so named from the relative color of the surface of the roots. But as they are derived from the same plant, and are essentially the same in properties and com- position, the division is of no practical utility, especially as they are received into this country often so intermingled, as to render a separation of them almost impossible. Ipecacuanha root is seldom seen by the druggist or practitioner of this country, except in powder, from which circumstance it is much liable to adulteration. The powder of the genuine article is of a grayish-yellow color, with a faint, bitterish, obscurely acrid taste, and a weak, musty, peculiar odor, which becomes stronger and nauseating during the process of pulverization ; in some persons it excites violent sneezing, in others a difficulty of breathing resembling asthma. It yields its properties to water, and still better to alcohol, spirits or wines. Boiling impairs its virtues. The bark of the grayish-black, or dark-brown variety, consists of an odorous concrete oil, wax, gum, starch, lignin, and emetia. The woody part contains but little emetia. The grayish-black variety is sup- posed to contain more emetia than the grayish-red. Emetia or emetine which is the active principle of the root, is prepared by removing the odorous fatty matter from the powder with ether, then exhausting the residue with boiling alcohol, then evaporating the alco- holic solution to dryness, and finally subjecting the extract to the action of cold water, which dissolves the emetia with some free acid, and leaves the wax and other matters. To separate the acid, and obtain pure emetia, treat the watery solution with magnesia, filter, and evaporate. The salt is thus decomposed, and the organic alkali being insoluble is precipitated with the excess of the magnesia. This precipitate is then to be washed with cold water, and digested in alcohol, which dissolves the emetia ; finally the alcoholic solution is evaporated, the residue redis- solved in a dilute acid, decolorizing the solution with animal charcoal, and precipitating the emetia by magnesia. Or it may be obtained by treating the powdered root with very dilute sulphuric acid, precipita- ting with magnesia, and treating the precipitate in the manner above directed. Pure emetia is whitish, without odor, very slightly bitter, pulverulent, permanent in the air, uncrystallizable, fusible at about 120°, decidedly alkaline, sparingly soluble in cold water and ether, more soluble in hot water, and very soluble in alcohol. It contains nitrogen among its con- stituents. With acids it forms neutral, soluble, bitter, acrid, and for the most part, uncrystallizable salts, whose solutions are precipitated by gallic and tannic acids. It is supposed to consist of 35 equivalents of carbon, 25 of hydrogen, 9 of oxygen, and 1 of azote, (C35 H25 09 N). The root furnishes but a very small proportion of pure emetia. Cephaelis Ipecacuanha. 321 Tannin, all astringents containing tannin or gallic acid, iodine, salts of iron, and acetate of lead, are incompatible with ipecacuanha. Properties and Uses.—Emetic in large doses ; nauseant and expectorant in smaller; and in still smaller doses, tonic, stimulant, carminative and dia- phoretic. Some authors suppose it to possess narcotic properties. Given in scruple doses, it operates as an active emetic, causing much nausea, contin- ued muscular straining, with a free secretion of mucus; vomiting, however, seldom takes place, until fifteen or twenty minutes after its administra- tion. It is inferior to no other emetic, being safe even in large doses, seldom producing painful spasms of the stomach or bowels, and causing less prostration of the vital forces than tartar-emetic ; it is best employed in combination with other emetics, as in the Compound Powder of Lobe- lia, which is much used among Eclectics, and is preferred to any other emetic in the early stage of febrile diseases, and in other instances where a severe succussion of the system is indicated. In spasmodic asthma, hysteria, pertussis, sore-throat, common catarrh, and stricture of the chest common in phthisis, ipecacuanha as an emetic will be found very beneficial. In menorrhagia, a scruple of the powder at bedtime followed by a saline cathartic in the morning, has, in the hands of several prac- titioners, promptly checked the discharge. In fevers and inflammatory affections, small diaphoretic doses have been highly beneficial. It will likewise act as a nauseant sedative in all local inflammatory diseases, for which purpose it may be extensively used, and will be found extremely valuable in peritonitis, even the worst form occurring in puerperal women, in pneumonia, in which it will assist expectoration, also in hem- orrhages, especially uterine hemorrhages. From three to ten grains will produce nausea, which may be continued for any length of time, and which is attended with more or less depression of the pulse, languor, moisture of the skin, and an increased mucus discharge from all the mucous tissues of the system, which renders it very useful in pulmonary and hepatic diseases. In doses of one quarter of a grain to one-half, it acts as a tonic, im- proving digestion, increasing the appetite, and is valuable in some forms of dyspepsia. In doses of half a grain to two grains, administered every three or four hours, it produces perspiration, and is beneficial in febrile and inflammatory diseases ; combined with opium, its diaphoretic influ- ence is greatly augmented, as seen in the Powder of Ipecacuanha and Opium. In diarrhea and dysentery, both acute and chronic, it has been regarded as a valuable remedy, free vomiting being first induced, after which, two or three grains, with occasionally one-eighth of a grain of sulphate of morphia, may be given every four hours. Combined with podophyllin, it increases the activity of that resinoid, and induces perspi- ration. An excellent remedy for dysentery is, one grain each of leptan- drin and ipecacuanha, and half a grain of podophyllin, to be given every three hours until it operates freely. Sometimes ipecacuanha may be 21 322 Materia Medica. advantageously combined with other emetic agents, as bloodroot, lobelia, etc., to render emesis more prompt, certain, and effectual. In all cases where this drug cannot be given by the mouth,-it may be used in injec- tion, adding two drachms of the powder to one.pint of warm water, for an adult,—it will operate kindly and thoroughly as an emetic. Recently, a liniment of ipecacuanha has been introduced into practice, for the treatment of incipient phthisis, certain rheumatic affections, chronic hydrocephalus, chronic inflammation of the synovial membrane of the knee, and infantile convulsions. As soon as the pustular eruption appears, the symptoms improve more or less rapidly, until a cure is effected. It is made of powdered ipecacuanha, sweet oil, of each, two drachms, lard half an ounce ; mix them well together. To be rubbed into the part affected, fifteen or twenty minutes at a time, and to be repeated three or four times daily, covering the part after each rubbing with flannel; in from 24 to 48 hours the eruption appears. It is stated, that an infusion of two drachms of ipecacuanha in a gill of hot water, and strained, will, if drank warm, prove emetic ; then if the same quan- tity of hot water is again added to the residue, strained, and drank cold, it will prove purgative ; and the same process repeated the third time, and used cold, becomes a valuable tonic. Emetia, the active principle of this drug, is so severe and uncertain in its aciion, that it is not used in medicine. Two grains of it will kill a large dog. A sixteenth of a grain vomited an old man severely. Off.

Description. — This plant, sometimes called Pond Dogwood, Globe Flower, etc., is a handsome shrub growing from three to fifteen feet high, much branched, bark smooth on the branches, rough on the stems. The leaves are opposite, ternate, with red petioles, oval, base acute, apex acuminate, margin sometimes undulate, smooth on both sides, sometimes slightly pubescent, entire, from three to five inches long, and two to three broad. The fiowers are terminal, forming round balls of a cream-white color, about an inch in diameter, resembling the globular inflorescence of the sycamore (Platanus Occidentalis), and are on peduncles about two inches long. Calyx tube produced above' the ovary, teeth obtuse, persistent. Corolla with a somewhat funnel-shaped tube, Cera Alba — Cera Flava. 323 with four ovate segments. Stamens not much longer than the corolla, with yellow anthers. Style filiform, much exserted, Avith a yellow stigma. Capsules small, crowded, formed of two half bivalve cells, with the valves opposite, each containing one seed. History.—This plant is found in most parts of the United States and Canada,-by the banks of streams and ponds, and in low, wet situations, flowering in July and August, having a peculiar and heavy odor. The wood is light and spongy. The bark is the part used, and possesses much bitterness. Water or alcohol takes up its virtues. Properties and Uses.—Tonic, febrifuge, aperient, and diuretic. The bark has been used with much success in intermittent and remittent fevers; and the inner bark of the root forms an agreeable bitter, which is often employed in coughs, and as a diuretic in gravel. The plant deserves further investigation. It has never been analyzed, but con- tains some volatile oil, and much bitter extractive. CERA ALBA. White Wax. CERA FLAVA. Yellow Wax. History.—Wax is a peculiar concrete substance, which exists in small quantities in various plants; it is likewise a product of the common bee, Apis Mellifica of naturalists, which constructs with it the cells for food and ova. It is a proper secretion of the insect, discharged in the form of scales under the wings of the belly. The wax produced by the bee is the officinal article, of which there are two kinds, Yellow wax and White wax. Yellow Wax is obtained directly from the comb, which, after having been deprived of its honey, is melted in boiling water, strained, again melted and poured into suitable vessels; as the liquid cools the wax concretes, forming the yellow wax of commerce. Our markets are chiefly supplied from the Western States and North Carolina, also from Cuba. It has a grayish-yellow color, a peculiar rather agreeable odor, and a slight peculiar taste. It possesses considerable firmness and tenacity, though rather soft and unctuous to the touch, but no greasi- ness, has a granular fracture, is smooth and glossy when cut with a knife, does not adhere to the fingers, nor to the teeth when chewed, is softened by a moderate heat, and melts at 142°; its specific gravity is 0.960 to 0.965. Its odor, color, and taste, depend upon some associated principle not forming any of its essential constituents. 324 Materia Medica. White Wax is prepared by exposing thin layers of yellow wax to air, sunshine, and moisture, when it loses its color, nearly all of its odor, and becomes yellowish-white. In factories where this bleaching process is carried on to a considerable extent, the melted wax is made to fall upon a revolving cylinder, kept constantly wet, upon which it concretes, forming thin ribbon-like layers, which are removed from the cylinders, spread upon linen cloths stretched on frames, and exposed to the air, and light; being occasionally watered and turned. To render it per- fectly white, this process has to be repeated two or three times, when it is melted and cast into small circular cakes. Chlorine will also decolor- ize it, but the wax becomes somewhat changed in its character. Pure white wax is white, shining, diaphanous in thin layers, inodorous, insipid, harder and less unctuous to the touch than the yellow, soft and ductile at 95° F., melts at 155° F., and of specific gravity 0.966. At a high temperature it boils, and in close vessels distils over with little alteration ; at a red heat its vapor inflames, burning with a dense white brightness. It is insoluble in water, cold alcohol, or ether, but is slightly soluble in boiling alcohol or ether, which deposits it upon cooling, It readily dissolves in fixed and volatile oils, and combines by fusion with fats and resins; boiled with caustic alkaline solutions it is imper- fectly saponified. The ultimate constituents of wax are twenty equiva- lents of carbon, twenty of hydrogen, and one of oxygen, (Cm H20 0). When treated with nitric acid, wax is almost entirely converted into succinic acid. According to Dr. John, wax consists of two proximate principles, Cerin and Myricin, the former constituting about 70 per cent. of the wax, fusible at 143°, soluble in boiling alcohol, partly saponifi- able by boiling with caustic potassa, and yielding margaric acid, a little oleic acid, and an unsaponifiable fatty matter called Cerain; the latter fusible at 149°, sparingly soluble even in boiling alcohol, and incapable of undergoing saponification. Lewy and Ettling consider cerin, myricin, and cerain to be isomeric, but Hess affirms they are not distinct princi- ples at all, and that wax is essentially a single proximate principle. Mr. B. C. Brodie considers cerin, when pure, as an acid having the constitu- tion Cj-i H54 Oi, and which he terms Cerotic acid, which is fusible at 172° F., and on cooling concretes into a very crystalline mass. Myricin, when entirely freed from cerotic acid, is saponifiable with difficulty, and from the results of saponification he isolated Palmitic acid (Ci2H32 0() and a peculiar substance, Melissine (Ceo He2 04), which he views as a wax-alcohol, convertible into mellissic acid by the loss of two equivalents of hydrogen, and the gain of two of oxygen. Both yellow and white wax are liable to adulterations. Resin may be suspected by the fracture being smooth and shining instead of granu- lar, also by its solubility in cold alcohol. Insoluble substances may be discovered and separated by melting and straining the wax. Tallow and suet, by the greasiness imparted, by the softness they communi- Cerevisi^e Fermentum. 325 cate to the wax, and its greater fusibility, also by its unpleasant odor when melted. Fatty matters may also be detected by their rendering hot lime-water turbid, when agitated with chips of the suspected wax, and then allowed to rest. Chloroform dissolves stearin and stearic acid completely, but only 25 per cent, of wax; then, if wax, treated with six or eight parts of chloroform, loses more than one-fourth of its weight, it is impure. If the wax contains starch, boil it in water and add tinc- ture of iodine to it, which will produce a blue color. Pereira states that the whiteness of the circular cakes of wax is owing to the presence of spermaceti, and that pure wax is yellowish-white. (For Myrtle wax see Myrica Cerifera.) Properties and Uses. — Wax has but little effect upon the system, though it has been recommended in diarrhea, dysentery, and inflamma- tion of the alimentary mucous membrane combined with olive oil, and the yelk of egg. Its principal employment is in the formation of oint- ments, cerates, and plasters, of which it forms an ingredient imparting to them due consistence and tenacity. CEREVISI^E FERMENTUM. Yeast. Preparation.—When an infusion of malt, (barley steeped in water, fermented, and dried in a kiln,) technically called Wort, is subjected to the process of fermentation, a dirty, grayish-brown substance, gradually separates, forming in part a frothy scum, and partly a sediment; this is yeast, or barm. History.—Yeast is a floceulent, frothy, somewhat viscid semifluid, of a sour, vinous odor, and a bitter taste ; it is a very mixed substance, containing water, alcohol, carbonic, acetic and malic acids, potassa, lime, and saccharo-mucilaginous extract. At 60° or in a damp atmosphere, it soon undergoes putrefaction, and exposed to a moderate heat, it be- comes dry, hard, and brittle, and may then be preserved for a long time, though with the loss of much of its peculiar power. Yeast is insoluble in alcohol or water. Its most important property is, that when placed in contact with saccharine solutions at a temperature between 50° and 80°, it excites vinous fermentation in them, converting their sugar into carbonic acid and alcohol. This property it owes to its azotized globules or cells, which may be seen in it, when examined with a microscope, appearing as minute transparent vesicles, containing one or more granules. This property is much impaired by drying the yeast, and destroyed by a heat of 212°, the addition of strong alcohol, of several of the acids, or by continued trituration until all the vesicles have burst and lost their 326 Materia Medica. structure. It is also destroyed by boiling water, pyroligneous acid, salts of mercury, essential oils, etc. Properties and Uses.—Stimulant, tonic, nutritious, antiseptic, and laxative. Used in typhoid fevers by mouth and injection, and in tym- panitis by enema. In all malignant ulcerations of the throat and mouth, in diseases where there is a disposition to putridity, in scarlatina, and low stao-es of fever, with or without the addition of olive oil, which renders it more laxative, it will be found highly beneficial. Externally, in combination with elm bark and charcoal it forms an excellent emol- lient and antiseptic poultice in sloughing ulcers, stimulating the vessels, removing the tendency to gangrene, and correcting the fetor. In the recent furunculoid epidemic which existed in this country and Europe, given internally, in conjunction with quinia, yeast was found effectual in the treatment of boils, carbuncles, and felons. The dose of yeast is from half an ounce to an ounce, every two or three hours. Yeast has been advised in diabetes mellitus in doses of a fluidrachm three or four times a day, taken immediately before meals. It has in some instances proved efficacious, and is supposed to act by decomposing sugar or preventing its abnormal production in the stomach. Off. Prep.—Cataplasma Fermenti. CETACEUM. Spermaceti. A PECULIAR CONCRETE SUBSTANCE OBTAINED FROM THE SPERMACETI WHALE. Preparation.—Spermaceti is obtained from the Cachalot or Sperm whale, the Physeter Macrocephalus of naturalists, a species of the family Cetacea; it is a gregarious animal, inhabiting the Pacific ocean, the waters of the Indian Archipelago, and the Chinese seas. It varies in size, being from fifty to eighty feet in length, with a huge, quadrangular head, from twenty to thirty feet, or more, in circumference, and which constitutes about a third of its whole length. Spermaceti is .found in various parts of its body, in small proportions, dissolved in its blubber, but that which is met with in commerce, is obtained from large cavities in the upper part of the head; these are divided into numerous cells, which are filled with a milky, oleaginous solution of spermaceti. From a large whale forty to sixty hundred weight of this fluid may be collected. It is removed from the cavities and boiled to separate the oleaginous matter from the solid substance, and as it cools, the spermaceti crystal- lizes. The oil is then drained off as much as possible, and the remainder is removed from the spermaceti by powerful pressure. The crude Cetaceum. 327 spermaceti is subsequently purified by fusing and skimming it, then fusing it in weak ley of potassa, and finally by a third fusion at a gentle heat; after which it is solidified in tin molds. History.—Spermaceti is concrete, crystalline and foliaceous in texture, white, pearly, tasteless, inodorous, friable, soft, and somewhat unctuous to the touch ; pulverizable on the addition of a little alcohol or almond- oil, of specific gravity 0.943, fusible at 112° F., combustible, insoluble in water, sparingly soluble in cold alcohol, more soluble in boiling alco- hol, ether, and oil of turpentine, but deposited as the liquids cool, and readily soluble in volatile oils, fixed oils, or fused fats. The mineral acids do not affect it, except the sulphuric, which decomposes and dis- solves it. Long exposure to the air renders it yellow and rancid, in consequence of its containing a little oil, but it may again be purified by washing it with a warm ley of potassa, or by boiling in alcohol, which deposits the pure spermaceti as it cools. Spermaceti, when deprived of oil by means of an alkali, becomes a pure proximate principle, interme- diate between wax and the concrete oils, and presenting all the leading properties of the ordinary article, but less unctuous, rather harder, and fusible only at 120°; it is then termed Cetin, and is soluble in forty parts of boiling alcohol of sp. gr. 0.821. When boiled in a solution of caustic potassa, cetin is partially saponified, forming a brittle soap, composed chiefly of margarate of potassa, oleate of potassa, and a crystalline principle called Ethal, and which soap is not wholly soluble in water. Cetin is a compound of ethal, (hydrated oxide of cetyle,) with ethalic or cetylic acid, (C32 H31 Os HO). When melted or dissolved in hot alcohol it crystallizes beautifully; when acted on by nitric acid, it yields first, pimelic acid, (C7 Ho O4); which is then oxidized into adipic acid, (CuHi-'O10); which is finally converted into succinic acid, (Ct Hi Oi, HO=S, HO). Cetin or pure spermaceti consists of 81.66 per cent, of carbon, 12.86 hydrogen, and 5.48 oxygen. Properties and Uses. — Demulcent, much used among children in domestic practice in coughs, colds, and catarrhal affections, combined with equal parts of loaf sugar, and in irritations of the intestinal mucous membranes. An emulsion may be made by first mixing it wilh half its weight of olive oil, then with powdered Gum Arabic, and lastly with water gradually added. Spermaceti forms a useful ingredient of several cerates and ointments. Spermaceti enters into the formation of a crayon which is of much value to chemists, druggists, and others, inasmuch as it enables them to write upon clean glass, the contents of bottles, etc., as labels or otherwise. It is made by fusing in a cup four drachms of spermaceti, (or stearine) three drachms of tallow, and two drachms of wax ; after which, six drachms of red-lead, and one drachm of potassa are to be stirred into it, keeping the whole mass warm for half an hour, and then pour it into glass tubes the thickness of a lead-pencil. After 328 Materia Medica. rapid cooling, the mass may be screwed up and down in the tube, and cut to the finest point with a knife. Off.

Description.—Iceland Moss is a perennial, foliaceous plant, from two to four inches high ; thallus erect, tufted, olive-brown, paler on one side, laciniated, channeled, and dentato-ciliate, the fertile laciniae very broad. Shields brown, appressed, flat, with an elevated border. History.—This lichen is a native of Britain and the northern countries of Europe, particularly Iceland. It is of various colors, being grayish- white, brown, and red in different parts; has a bitter, mucilaginous, somewhat astringent taste; is inodorous, absorbs more than its weight of water when steeped, rendering the water bitter if warmed, is converted into a mucilaginous pulp by long chewing, and when boiled in water the decoction becomes a firm jelly on cooling. The bitter principle, which may be removed by weak alkaline solutions, is called Cetrarin, and is used in Italy instead of Cinchona. It may be obtained by boiling the coarsely-powdered moss for half an hour in four times its weight of alco*- hol of 0.883. When tepid, the solution is to be filtered, and treated with diluted muriatic acid, in the proportion of three drachms to every pound of moss employed. Water, to the amount of four times the volume of the liquid, is then to be added, and the mixture left for a night in a closed matrass. The deposit which forms, is collected on a filter, allowed to drain as much as possible, and submitted to the press. To purify it, break the mass into small pieces, and while still moist, wash it with alco- hol or ether, then treat it with two hundred times its weight of boiling alcohol, which dissolves only the cetrarin; as the liquid cools, this is, for the greater part deposited, and the remainder may be obtained by evaporation. One pound of moss will thus yield about 133 grains of cetrarin. It is white, uncrystalline, light, permanent in the air, inodor- ous, and very bitter, especially in tincture. It is soluble in absolute alcohol, ether, and slightly so in water; alkalies form permanent com- pounds with it, from which it may be separated by acids with its original properties unchanged. Acids do not unite with it, and its solutions are neutral to test-paper. Concentrated hydrochloric acid converts it into a bright-blue coloring matter. It precipitates the salts of iron, copper, lead, and silver, and has been used in two-grain doses, repeated every two hours, with much success in intermittents. It is supposed to consist of cetraric acid, lichstearic acid, and thallocor. Chelidonium Majus. 329 The most important part of Iceland moss, is its nutritive principle, to which the name of Lichenin has been given. It may be obtained by macerating the chopped lichen for twenty-four hours, in eighteen parts of water, containing a 250th of its weight of carbonate of potassa—strain off the bitter solution without pressure, and remove the rest of it from the residuum by maceration with cold water, and simple straining. Boil the residuum in nine parts of water down to six, strain the decoc- tion, and squeeze what is left in the cloth, and then allow the strained liquor to cool. A firm jelly is formed, which cracks and throws out much of the water, and then dries into a hard, black, glassy-like sub- stance. The black coloring matter may be removed by boiling again, straining, cooling, and drying; upon which the lichenin is obtained in thin, transparent, and tough plates of a yellowish color. Cold water renders it gelatinous, boiling water dissolves it, forming a jelly on cool- ing ; alcohol and ether do not affect it. Iodine renders its watery solu- tion blue, and it is converted into sugar by sulphuric acid, and into oxalic acid by nitric acid. It consists of carbon, oxygen, and hydro- gen, and in some respects resembles amidin. Properties and Uses.—Demulcent, tonic, and nutritious. Used as a demulcent in chronic catarrhs, chronic dysentery, and diarrhea, and as a tonic in dyspepsia, convalescence, and exhausting diseases. Boiled with milk it forms an excellent nutritive and tonic in phthisis, and gen- eral debility. Its tonic virtues depend upon its cetrarin, which, if removed, renders the lichen merely nutritious.

Description.—This plant, sometimes known as Tetterwort, is an ever- green perennial, with a stem from one to two feet in hight, branched, swelled at the joints, leafy, round, smooth. The leaves are smooth, spreading, very deeply pinnatifid ; leaflets, in from two to four pairs, from one and a half to two and a half inches long, and about two-thirds as broad, the terminal one largest, all ovate, cuneately incised or lobed ; the lateral ones sometimes dilated at their lower maroin near the base, almost as if auricled ; color of all a deep shinino- oreen. Flowers bright-yellow, umbellate, on long, often hairy stalks. Umbels thin, axillary, pedunculate. Calyx tawny, often hairy. Petals four, entire, yellow, and very fugacious. Stamens numerous. Capsules long, 330 Materia Medica. torulose, two-valved, one celled. Seeds black and shining, each with a whitish deciduous crest. History. — Celandine is indigenous to Europe, and is extensively naturalized in the United States, growing in Avaste places, and flower- ing throughout the summer. The whole plant is very brittle, and ex- udes when broken, an orange-colored, fetid juice, the taste of which is intensely bitter and acrid, occasioning a sense of burning in the mouth and fauces, which lasts for some time. The root is more power- ful than the stems, and is usually preferred. Drying diminishes its activity. It yields its virtues to alcohol or water. Analysis has detected in this plant, a deep-yellow, bitter, resinous substance, an orange-colored, nauseous, and bitter gum-resin, mucilage, albumen, free malic acid, silica, and various salts. More recently a peculiar acid has been detected in it, termed Chelidonic acid; an alkaline principle, forming neutral red salts with acids, which are narcotic and poisonous, denominated Chelerythine; it is a gray powder, and excites violent sneezing when snuffed into the nostrils ; another alkaline principle, bitter, insoluble in water, and forming crystallizable "salts, called Cheli- donin, (Cto H20 N3 0); and lastly a neuter, yellow, crystallizable, bitter principle, termed Chelidoxanthin. Chelerythin may be obtained by forming a strong ethereal tincture of the celandine root; through this pass muriatic acid gas, and dry the precipitated muriate which is insoluble in ether. Then dissolve it in hot water, filter, precipitate by ammonia, dry the precipitate, dissolve it in ether, decolorize by animal charcoal, again precipitate by muriatic acid gas, and decompose the muriate, by ammonia, as before. Properties and Uses.—Stimulant, acrid, alterative, diuretic, diapho- retic, and purgative. Used internally in decoction or tincture, and externally in poultice or ointment, for scrofula, cutaneous diseases, and piles. Likewise useful in hepatic affections, and is supposed to exert a special influence on the spleen. As a drastic hydragogue it is fully equal to gamboge. The juice when applied to the skin produces inflam- mation and even vesication, and has long been known as a caustic for the removal of warts, also applied to indolent ulcers, fungous growths^ etc., and is useful in removing specks and opacities of the cornea, and in curing ringworms. Dose of the powdered root, from half a drachm to one drachm ; of the fresh juice, from thirty to forty drops, in some bland liquid ; of the tincture, from one to two drachms ; of the aqueous extract, from five to ten grains.

Description.—This plant, likewise known by the names of Snakehead, Turllebloom, Turtlehead, Salt-rheum weed, etc., is a herbaceous plant, with a perennial root, and erect, somewhat quadrangular, branching stems, from two to four feet high. The leaves are opposite, smooth, oblong-lanceolate, acuminate, serrate, short-petioled, and of a dark, shining green above. The flowers are large, inodorous, terminal in a dense short spike, somewhat resembling the head of a tortoise ; each floAver is sessile and furnished with three ovate, acute and entire bracts. Corolla ringent, white, often tinged with red or purple, ventricose, con- vex above, five-lobed, two-lipped, the lower lip bearded within. Calyx with five unequal imbricated segments, oblong and obtuse. Stamens didynamous, with woolly anthers ; and a short sterile, hairy filament. Ovary ovate, with a long, exsert style, bending downward. Capsule oval, tvv .'-celled, two-valved, with numerous small, winged seeds, with membranaceous margins. History.—This valuable medicinal plant is found in the United States in wet situations, and blossoms from July until late in the autumn; the flowers are large and ornamental, varying in color, in the numerous varieties, from pure white to purplish, and resemble in form the head of a snake or turtle. The leaves are exceedingly bitter, but inodorous, and communicate their properties to both water and alcohol. No ana- lysis has been made of them. Properties and Uses.—Tonic, cathartic, and anthelmintic. Especially valuable in jaundice and hepatic diseases, likewise for the removal of worms, for which it may be used in powder or decoction, internally, and also in injection. Used as a tonic in small doses, in dyspepsia, debility of the digestive organs, and during convalescence from febrile and inflammatory diseases. Recommended in form of ointment as an appli- cation to painful and inflamed tumors, irritable and painful ulcers, inflamed breasts, piles, etc. Dose of the powder one drachm ; of the tincture, one or two fluidrachms ; of the decoction, one or two fluid- ounces.

Description.—This plant, known also by the name of Jerusalem Oak, has a perennial and branched root, with an upright, herbaceous, much branched, deeply-grooved stem, rising from two to five feet in hight. The leaves are alternate or scattered, oblong-lanceolate, deeply sinuate, or dentate, nearly sessile, conspicuously veined, attenuated at both ends, of a yellowish-green color, and studded beneath with small, globular, oily dots. The fiowers are very numerous, small, of the same color as the leaves, and arranged in long, slender, axillary, or terminal racemes. Calyx with five oval, concave segments. Stamens opposite the lobes of the calyx, and about as long. Styles three, sometimes two, longer than the stamens. Seed small, lenticular, covered by the persistent calyx. History.—Chenopodium is found growing in waste places in almost all parts of the United States, flowering from July to September, and ripening its seeds throughout the autumn, at which time they should be collected. The whole plant has a strong, heavy, disagreeable odor, depending on the presence of a volatile oil, which is most abundant in the seeds. This oil is at first light-yellow in color, but becomes darker by age and exposure to light. The whole plant is occasionally employed, but the seeds only are officinal. When dried, they are of a greenish- yellow or brownish color, irregularly spherical, very small, very light, and have a bitterish, warm, pungent taste, with the peculiar odor of the plant. Wormseed oil is obtained from them by distillation. Properties and Uses.—Anthelmintic and antispasmodic. It is used in various forms to expel the lumbrici in children, in various forms, as the expressed juice, electuary, or decoction. The dose of the juice, is a tablespoonful repeated night and morning ; of the decoction, prepared by boiling an ounce of the fresh plant in a pint of milk, with the addi- tion of some aromatic, a Avineglassful; of the electuary, made by tho- roughly mixing the pulverized seed in honey or syrup, one or two scruples. But the essential oil, on which the vermifuge properties depend, is the best form, and is more generally employed. Its dose is from four to eight drops mixed with sugar, or in emulsion, to be given morning and evening, for four or five days successively, and then, as with the other forms of administration, it should always be followed by a purgative. Among Eclectics it is used in various combinations. Take of oil of Wormseed and Tansy, of each one ounce, Spirits of Turpen- tine one ounce and a half, Castor Oil, one pound. Mix. Dose, for a Chimaphila Umbellata. 333 child, a teaspoonful every hour, until it operates; for an adult, a table- spoonful. The oil has likewise been reputed beneficial in amenorrhea. The G. Ambrosoides, which has been successfully used in chorea, and the C. Bolrys, which has been used with advantage in catarrh and humoral asthma, as an expectorant, are both indigenous, and though less powerful, possess somewhat similar properties ; and, indeed, from the superior powers of the C. Anthelminticum, it might possibly be found of more benefit in these affections, than the above. Off. Prep.—Oleum Chenopodii; Mistura Chenopodii Composita ; Mistura Olei Composita.

Description.—This plant is known by various other names, as Winter- green, Prince's Pine, Ground-Holly, etc. ; it is a small evergreen, nearly herbaceous, perennial herb, with a creeping, yellowish rhizoma, from which are sent several simple, erect, or semi-procumbent stems, some- what angular, marked with the scars of former leaves, and ligneous at their base ; they grow from four to eight inches in hight. The leaves are in two or more irregular whorls, from tAvo to three inches long, and about one-fourth as wide, cuneate-lanceolate, acute at the base, sharply serrate, on short petioles, coriaceous, shining, of a uniform dark-green color, paler below, and not spotted. The fiowers are corymbose, nod- ding, of a light-purple color; the pedicels Avith linear-subulate bracts about their middle, one-sixth of an inch long. Calyx small, consisting of five roundish, acute teeth or segments, much shorter than the corolla. Corolla is composed of five roundish, concave, spreading, cream-colored petals, exhaling a fragrant odor, and tinged at the base with purple. Stamens ten, hypogynous; filaments sigmoid, the lower half fleshy, tri- angular, dilated, and slightly pubescent at the edges ; the upper half filiform. Anthers two-celled, each cell opening by a short, round, tubu- lar orifice, which points downward in the bud, but upward in the flower. Pollen white. Ovary globular, depressed, furrowed, obscurely five- lobed, with a funnel-shaped cavity at top, and supporting a large, pel- tate, convex, obscurely five-rayed stigma. Style short, straight, half as long as the ovary, inversely conical, inserted in the cavity of the ovary, and concealed by the stigma. Capsule erect, depressed, five-celled, 334 Materia Medica. five-valved, the partitions from the middle of the vahTes. Seeds numer- ous, linear, and chaffy. History.—This beautiful evergreen is a native of the northern lati- tudes of America, Europe, and Asia, and is found in the United States growing under the shade of Avoods, and prefers a loose, sandy soil, enriched by decaying leaves. It flowers in June and July. The fresh leaves have a fragrant odor when bruised, but Avhen dried have scarcely any smell, Avith a pleasantly bitter, astringent and sweetish taste. The whole plant is officinal. Boiling water, or alcohol extracts the active properties. The plant contains a large proportion of bitter extractive, an acrid and volatile principle, resin, gum, lignin, and saline substances. Properties and Uses. — Diuretic, tonic, alterative, and astringent. The fresh leaves when bruised and applied to the skin, act as vesicants and rubefacients. It is especially useful in scrofula, and chronic rheu- matic and nephritic affections. The decoction alone has cured ascites, and has been advantageous in strangury, chronic gonorrhea, and catarrh of the bladder; and as an antilithic it is said to diminish lithic acid in the urine. In dropsy it cannot always be relied on to the exclu- sion of other more active measures, and is better adapted to cases accompanied Avith much debility and loss of appetite. In urinary dis- orders, it may be used as a substitute for the uva ursi, to Avhich it is preferable on account of being less offensive to the stomach. In many cutaneous diseases, it has proved very efficacious. Dose of the decoction, from one to four fluidounces three times a day; of the extract, from ten to twenty grains, three or four times a day ; a syrup may be prepared, by macerating four ounces of the finely-bruised leaves, in eight fluidounces of Avater for thirty-six hours, then subject the whole to percolation till a pint of fluid is obtained, evaporate to half a pint, and add twelve ounces of sugar. Dose, one or two tablespoonfuls. The Chimaphila Maculata, or Spotted Wintergreen, may be known from the above by its leaves, which are opposite, or in threes, lanceolate, acuminate, rounded at the base, where they are broader than near the summit, remotely serrate, of a deep olive-green color, and veined with greenish-white. The C. Umbellata leaves are broader near the summit, tapering toward the base, of a uniform shining green color, serrated, and not marked with the whitish line along the midvein and veinlets. The C. Maculata is probably possessed of similar powers with the officinal article and may be used as a substitute. An extract of it is reputed to have cured epilepsy.

THE BARK OF THE ROOT. Description.—A subscandent shrub, somewhat resembling the Jas- mine, with opposite branches. Leaves oval, acuminate, or sometimes obtuse, on a short petiole ; they are entire, very smooth, and furnished Avith two short, acuminate stipules, which are connate at their edges. The flowers are in axillary racemes, generally shorter than the leaves; they are usually secund ; at first they are white and inodorous, and afterward yellow and fragrant. The fruit is a small, white, compressed berry. There are several varieties, differing in the form of the leaves, and more or less scandent character of the shrub. History. —This plant, sometimes called Snowberry, is a native of the West Indies, South America, and also of the sea-coast of Florida. The root, as found in commerce, is of a reddish-brown color, in cylindrical pieces of various sizes and lengths, somewhat contorted, slightly wrinkled longitudinally, with occasional small asperities, and having a thin, brittle, reddish-brown bark externally, and an internal ligneous portion. The cortical part, which contains the medical virtues, is of a bitter, disagreeable taste, somewhat acrid and astringent, and possesses an unpleasant odor. Water or alcohol extracts its active principles. Properties and Uses. — Tonic, diuretic, purgative, and emetic. In moderate doses it gently excites the circulation, increases the discliarge of urine, and produces evacuations from the bowels, but is rather slow in its operation. If warm drinks are used, and the surface of the body kept warm, it will produce diaphoresis, and not purge. In large doses it operates powerfully as an emetic and cathartic. It has been found efficient in dropsy, amenorrhea, rheumatism, syphilis, and osteocopus. In Brazil it is used by the natives as a remedy for the bites of poisonous snakes. It may be used in substance, decoction, tincture, or extract. Dose of the powdered bark of the root, as a diuretic and purgative, from twenty to sixty grains ; of the aqueous or spirituous extract, which is preferred, from ten to twenty grains. CHLOROFORMUM. Terchloride of Formyle. CHLOROFORM. Preparation. — Mix Chlorinated Lime ten pounds; first with Water, three gallons and a half, and then with Alcohol, two pints, in a distillatory 336 Materia Medica. vessel having the capacity of about six gallons. Distil with a brisk heat into a refrigerated receiver, and Avhen the temperature approaches to 176°, withdraw the fire, in order that the distillation may proceed by the heat derived solely from the reaction of the materials. When the distillation slackens, hasten it by a fresh application of heat, and con- tinue to distil until the liquid ceases to come over Avith a sweet taste. Separate the heavier layer of liquid in the receiver from the lighter by decantation, and, having washed it first Avith water, and then with a weak solution of carbonate of soda, agitate it thoroughly with powdered chloride of calcium, and distil it off by means of a water-bath, stopping the distillation when eleven-twelfths of the liquid have come over. The residue, together with the light liquid of the first distillation, may be reserved for use in a second operation. History.—Chloroform was discovered in 1831 by Mr. Samuel Guthrie, of Sackett's Harbor, N. Y., and also by Leibig in Germany, and Soube- rain in France, at about the same time. Guthrie obtained it by distilling a gallon from a mixture of three pounds of chlorinated lime, and two gallons of alcohol, sp. gr. 0.844, and rectifying the product by redistil- lation, first, from a great excess of chlorinated lime, and afterward from carbonate of potassa. He thus obtained pure chloroform, sp. gr. 1.486, free from alcohol, and rendered pure by washing it with a strong solu- tion of carbonate of potassa. Chloroform is a limpid, colorless, volatile, neuter liquid, having a bland ethereal odor, and a hot, aromatic, sweetish taste. Litmus paper is not bleached nor reddened by it. It is not inflammable, but renders the flame of an alcohol lamp yellow and fuliginous. Its density is from 1.48 to 1.5, and it boils at 142°. It dissolves readily in ether or alco- hol, but is scarcely soluble in Avater or sulphuric acid; its alcoholic solution Avhen moderately diluted Avith water forms an aromatic saccha- rine liquid of a very grateful taste. An abundance of Avater decomposes a strong alcoholic solution, the chloroform separating and subsiding, and the alcohol uniting with the water. When pure, it has no action on potassium, sulphur, or phosphorus, but is capable of dissolving amber, shell-lac, copal, caoutchouc, gutta percha, iodine, bromine, resins, wax, fats, volatile oils, the organic alkalies, and large proportions of camphor; and as a general solvent, its non-inflammability renders it superior to alcohol or ether. It is composed of three equivalents of chlorine, and one of formyle. Chloroform has an extensive range of solvent power, and will prove a most valuable auxiliary to the chemist and pharmaceutist. According to M. Lepage the following is the solvent pow*r of chloroform in rela- tion to various bodies: Mastic, colophony, elemi, tolu, and benzoin, are dissolved in all proportions, forming solutions, some of which might prove useful as varnishes. Copal and caoutchouc also dissolve, but more readily hot than cold. Amber, sandarac, and shell-lac are only Chloroformum. 337 partially dissolved, either with or without heat. Their constituent resins may be thus separated. Olibanum dissolves but slightly, hot or cold. Guaiacum and scammony resin dissolve readily, while jalap resin is insoluble; it merely softens and floats on the surface like pitch. Gam- boge and dragon's-blood yield some substance and their fine color to the solvent, and might be advantageously used as varnishes. Fixed oils and fats, dissolve readily, in all proportions. Wax yields 25 per cent. of soluble matter to this solvent. All volatile oils are soluble. Iodine, bromine, phosphorus, and sulphur are soluble, the two last only slightly. Styracin, piperin, naphthalin, cholesterin, and cantharidin are very soluble; picrotoxin, slightly so; paraffin only when hot, separating as the liquid cools; while amygdaline, phloridzin, salicin, digitalin, cytisin, urea, hematin, gluten, and sugar are insoluble. Benzoic and hippuric acids are very soluble, tannic but slightly, and tartaric, citric, oxalic, and gallic acids are insoluble. Quinia, veratria, emetia, narcotina, nico- tina, conia, and atropia are easily soluble, strychnia with less readiness, and appears to undergo a change in its morphic condition; brucia is moderately soluble, but morphia and cinchonia are insoluble. Tartar emetic, citrate and lactate of iron, the acetates of soda and potassa, valerianate of zinc, and acetate of lead are all insoluble. Sulphate and muriate of strychnia are soluble, while sulphates of quinia, and of mor- phia, and muriate of morphia, are insoluble. Corrosive sublimate dis- solves very readily, but the iodide, bromide, chloride, and ferrocyanuret of potassium, the chloride of sodium, muriate of ammonia and the iodides of mercury and potassium are all insoluble. The iodates, chlo- rates, nitrates, phosphates, sulphates, chromates, borates, arseniates, and alkaline hyposulphates, are insoluble, as are also nitrate of silver, sulphate of copper, and probably all the metallic oxysalts. This article thus affords a most valuable means of readily separating resin of guaia- cum from jalap resin, cinchonia from quinia, and narcotine from morphia. One per cent of chloroform added to milk, preserved it unchanged for one month, so that it was boiled without coap-ulatinof. When chloroform is impure, owing to the presence of alcohol or ether, its specific gravity is lower. To determine its purity, it has been recom- mended to let fall a drop of the suspected chloroform in a cool mixture of equal weights of concentrated sulphuric acid and water, the sp. gr. of the mixture being 1.38; good chloroform will sink in it. M. Mialhe recommends for detecting the presence of alcohol, to drop a small quantity of the chloroform in distilled water; it remains transparent at the bottom of the glass, if pure; but the smallest proportion of alcohol gives a milky appearance to the globules. The most injurious impuri- ties are the chlorinated pyrogenous oils, which cause distressing sickness and headache, when inhaled, or even smelt; to detect these, mix the chloroform in quantity, say several ounces, with an equal volume of pure and strong sulphuric acid; if pure, the mixture is not colored, but 22 338 Materia Medica. if these oils be present, the acid is colored from a yellowish to a reddish brown, according to the amount of impurity present. Another test, is to pour some chloroform on the hand, when pure, it quickly evaporates, and leaves scarcely any odor, but if these oils are present, they are recognized by their peculiar offensive, acrid, and penetrating odor, while the odor of the chloroform has dissipated. Properties and Uses.—Internally, a sedative narcotic. Has been used successfully in asthma, spasmodic cough, scarlatina, atonic quinsy, hys- teria, lead-colic, cancer, neuralgic affections, and in intermittents. It may be administered in doses of from forty to eighty drops, suspended in water by means of gum arabic or yelk of an egg, Avhich may be repeated, if necessary, every hour or two, until some effect is produced on the system. When the pyrogenous oils are present, its internal administration is liable to produce nausea. The solution of camphor in chloroform is an elegant form of administering that medicine. Exter- nally, it has> been used as a local application, in form of Avash, injection, or gargle, in cancer, senile gangrene, sloughing ulcers, profuse uterine discharges, and foul ulcers of the throat; it lessens pain, corrects fetor, and promotes the separation of diseased parts. It may be used for these purposes, diluted with water, in the proportion of one or two drachms of the chloroform to a pint of water. It has proved successful in dysmenorrhea, being brought into contact with the os uteri by means of a sponge; also in swelled testicle and acute spinal tenderness, neu- ralgia, rheumatic ophthalmia, and in the form of an ointment to papu- lous eruptions, in the proportion of a fluidrachm of chloroform to ten drachms of lard. When applied to the sound skin, it is generally used undiluted, by means of lint or soft rags, covered with oiled silk to pre- vent evaporation. When thus used it should always be pure, as, if it contains absolute alcohol, it acquires caustic properties. Chloroform is also used by inhalation as an anaesthetic agent, and is considered to possess some advantages over ether, from the smallness of the dose, its more prompt action, its more agreeable effects, its less tenacious odor, its greater cheapness, and the readiness with which it may be exhibited. As an anaesthetic it is principally used in surgery and midwifery, for the purpose of relieving pain, and facilitating labor. The effects usually produced by the inhalation of a full dose of chloro- form, are: the rapid production of coma, relaxation of the muscles, slow and often stertorous breathing, incoherent talking or muttering, upturning of the eyes, and total insensibility to pain, from whatever cause. This insensibility is generally produced in one or two minutes, and continues for five or ten minutes; but it may be kept up for several hours, by renewing the inhalation from time to time. Sometimes froth- ing of the mouth takes place, and occasionally twitches of the face and limbs; at other times, from coughing or other circumstances it may be Chloroformum. 339 a long time before its effect is induced, but which may be obviated by holding it, at first, at a little distance from the nostrils, that it may be mixed with atmospheric air, and gradually approach it. Its immediate effects are followed by a drowsy state, sometimes by quiet sleep, and, generally, no recollection of incidents occurring during the state of insen- sibility is retained. Being a relaxing agent as well as remedy for pain, its inhalation has been successful in hiccough, hysteria, asthma, nephritic colic, tetanus, hydrophobia and neuralgia; it has also been employed with success for the reduction of strangulated hernia, and as a hypnotic in delirium tre- mens and the noisy forms of chronic insanity. The dose for inhalation is a fluidrachm, or more, which should be repeated in three or four minutes, if the desired effect should fail to be produced. The best inhaler is a handkerchief, closely rolled up, and held in the hand, having a concavity which is to be imbued with the chloroform, and then held to the mouth and nose. The moment insen- sibility is produced, the inhalation should be suspended, and, if con- sciousness return too soon, it should be cautiously renewed. Persons affected with epilepsy or organic disease of the heart, should not be placed under its anaesthetic influence. It should never be administered after a full meal, as it may cause vomiting; and an impure article will almost always produce headache, nausea and vomiting. As chloroform may and has produced unfavorable as well as serious effects, the operator ought always to be provided with a bottle of strong aqua ammonia, and whenever these unpleasant symptoms arise, the patient should be made to inhale it from another handkerchief imbued with it in the same manner as named for chloroform, and be either restored to sensibility or not, as the case may require. The usual remedies when the effects of the chloroform inhalation proceed too far, are the horizontal posture, cold air fanned upon the face, cold water to the head and face, frictions and heat to the body and extremities, and ammonia to the nostrils; and if these fail, artificial respiration must be resorted to. To obviate these alarming effects it has been proposed to employ an agent composed of one-third pure chloroform and nearly absolute alcohol two-thirds, under the names of Tincture of Chloroform, or strong Chloric Ether. This is considered safer than chloroform, and more agreeable than ether. The stimulating properties may possibly obviate the depressing influence of the chloroform; and ether has sometimes been given in connection with chloroform, with a view to the same effect. A chloroform liniment has been made of oil of almonds two fluidounces, chloroform two and a half fluidrachms; mix together accurately. Pieces of flannel are to be soaked with this liniment, and applied to the painful part in cases of nervous headache, neuralgia, rheumatic, hepatic, nephritic, uterine, or intestinal pains, lead-colic, etc. By adding double the quantity of oil, it may be used 340 Materia Medica. for vaginal injections, which may be retained by a plug of cotton, in cases of dysmenorrhea, uterine neuralgia, or other painful affections of the uterus, bladder, or rectum. The fumes from burning the common Puff Ball, Lycoperdon Proteus, are said to be anaesthetic, but not equal to ether or chloroform. It ap- pears to possess a volatile narcotic principle, which is not taken up by alcohol, water, or strong alkaline solution. CHONDRUS CRISPUS. Irish Moss. Nat. Ord.—Algaceae. Sex. Syst.—Cryptogamia Algas. Description.—Irish Moss, or Carrageen, as it is frequently called, has a root-disk throwing up tufts of many flat, nerveless, slender, cartila- ginous fronds, from two to twelve inches in length, subcylindrical at the base, but immediately becoming flat, generally dilating from the base as they ascend, until they become three or four lines wide, and then dividing repeatedly and dichotomously, each division spreading and becoming narrower than the preceding one, and taking place at shorter and shorter intervals ; the summits are bifid, the segments linear, wedge-shaped, varying greatly in length, rounded or acute, straight or curved, and often twisted in such a manner as to give the curled appearance denoted in the specific name. Fructification round- ish or roundish-oval, subhemispherical. Capsules imbedded in the disk of the frond, prominent on one side, and producing a concavity on the other, containing a mass of minute, roundish, red seeds. Substance cartilaginous, in some varieties approaching to horny, flexible and tough. Color a deep purple-brown, often tinged with purplish-red, and paler at the summit, becoming greenish, and at length white in decay. History.—This plant grows upon rocks and stones on the coasts of Europe, especially on the southern and western coasts of Ireland ; said also to be a native of the United States. When collected, it is washed and dried. It is of a yellowish-white color when dried, translucent, of a feeble odor, and nearly tasteless. Boiling water dissolves it, forming a jelly on cooling. Cold water does not dissolve it, but swells it up. It contains starch, a large proportion of pectin or vegetable jelly, which Pereira proposes to call Carrageenin, supposing it to be a distinct prox- imate principle, also compounds of sulphur, chlorine and bromine, and some oxalate of lime, etc. Carrageenin may be known from gum, by its watery solution not affording a precipitate with alcohol; from starch, by not becoming blue with tincture of iodine ; and from pectin by giving no precipitate with acetate of lead, and no mucic acid by the action of nitric acid. Chrysanthemum Leucanthemum. 341 Properties and Uses.—Used in the form of decoction, with water or milk, as a nutriment, and as a demulcent in chronic pectoral affections, dysentery, diarrhea, and disorders of the kidneys and bladder. The decoction may be prepared by boiling half an ounce of the moss in a pint and a half of water, down to half a pint. Sugar and lemon-juice may be added to improve the flavor. It may be boiled in milk, when a more nutritious preparation is required. CHRYSANTHEMUM LEUCANTHEMUM. Whiteweed. Nat. Ord.—Asteraceas. Sex. Syst.—Syngenesia Superflua. the leaves and flowers. Description.—Chrysanthemum Leucanthemum, or the Leucanthemum Vulgare of Lamark, sometimes known as Ox-eye Daisy, is a perennial herb, with an erect, branching, furrowed stem, growing from one to two feet high ; the leaves are comparatively few and small, alternate, am- plexicaul, lanceolate, serrate, cut-pinnatifid at base ; the lower ones petiolate, with deep and irregular teeth ; the upper ones small and sub- ulate, and those of the middle sessile, deeply cut at base, with remote teeth above. Heads large, terminal, solitary. Disk yellow. Rays numerous and white. History.—This plant was introduced into this country from Europe, and is a very troublesome weed to farmers, in nearly every section. It generally grows from one to two feet high, and bears white flowers in June and July. The leaves are odorous and somewhat acid; the flowers are bitterish; they impart their virtues to water. Properties and Uses. — Tonic, diuretic, and antispasmodic. Large doses emetic. Used as a tonic instead of chamomile flowers, and has been found serviceable in hooping-cough, asthma, and nervous excita- bility. Very beneficial externally and internally in leucorrhea ; and its internal use has been highly recommended in colliquative perspiration. Externally, it has been used as a local application to wounds, ulcers, scald-head, and some other cutaneous diseases. Dose of the decoction, from two to four ounces, two or three times a day. Said to destroy, or drive away fleas. Off. Prep.—Decoctum Chrysanthemi. 342 Materia Medica. CICHORIUM INTYBUS. Succory. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia iEqualis. THE root. Description. — Succory, Chicory, or Wild Succory, is a perennial plant, having a spindle-shaped, fleshy, whitish, and milky root. The stem is solid, round, furrowed, hispid, very tough, growing two or three feet high. The radical leaves are spreading, above a span long, numer- ous, runcinate, toothed, roughish; cauline leaves, smaller, sessile, less lobed, the uppermost cordate, acuminate, entire. Flowers large, one or two inches in diameter, axillary, in pairs, sessile, placed rather remote on the long rather naked branches, and of a beautiful bright-blue color. Corollas flat, five-toothed. Involucre roughish. Anthers and stigma blue. History.—Succory is a native of Europe, but cultivated in this coun- try, where it grows in fields, and in roads along the fences, in neighbor- hoods which have been long settled; it bears large, compound, beautiful blue flowers, which appear in July and August. The root has a bitter taste, without any peculiar flavor, and imparts its virtues to water. Properties and Uses.—Tonic, diuretic, and laxative. The decoction, used freely, is said to have proved serviceable in hepatic congestion, jaundice, and other visceral obstructions in the early stages ; also in hemorrhage, gout, cutaneous eruptions, and even hectic fever and other febrile diseases. The usual form of administration is in decoction, an ounce or two of the root in a pint of water. When young and tender, the leaves are sometimes eaten as salad; the root, when dried and roasted is much used as a substitute for coffee among the French, which it resembles in taste but without the aroma. The Cichorium Endivia, or Garden Endive, is said, by some French physicians, to be a remedy for jaundice. CIMICIFUGA RACEMOSA. (Macrotys Racemosa.) Black Cohosh. Nat. Ord.—Ranunculaceaj. Sex. Syst.—Polyandria Di-Pentagynia. THE root. Description. — This plant, likewise variously known as Rattleroot, Black Snakeroot, Squawroot, etc., is a tall stately plant, having a ClMICIFUGA RACEMOSA. 343 large blackish, perennial root, with numerous long fibers, and a simple, herbaceous, smooth, furrowed stem, from four to eight feet high. The leaves are feAv, alternate, one nearly radical, large, decompound, and tripinnate ; upper one, bipinnate. The leaflets are ovate, oblong, ses- sile, opposite, three to seven, incised and toothed. The fiowers are fetid, small, white, in a long terminal raceme, with oftentimes one or more shorter ones at base; this raceme is at first bent, but gradually becomes erect; the flowers are supported on short pedicels, with a small subulate bract. Calyx white, with four rounded sepals. Petals small and shorter than the sepals, and cleft at their apex. Stamens very numerous, with yellow anthers. Pistil consists of an oval germ, with a lateral, sessile stigma. The fruit or capsule is ovoid, dry, with one cell, containing numerous flat, smooth seeds, which are packed horizontally in two rows. History.—Black Cohosh is a native of the United States, growing in shady and rocky woods, rich grounds, and on the sides of hills, from Maine to Florida, flowering in June and July. The root is the part gen- erally employed in medicine, though probably the seeds will be found as active; the root should be gathered early in the autumn and dried in the shade. It consists of a thick, irregularly-bent or contorted body or caudex, from one-third of an inch to an inch in diameter, often several inches in length, furnished with many slender radicles, and rendered extremely rough and jagged in appearance by the remains of the stems of successive years, which, to the length of an inch or more, are fre- quently attached to the root. The color is externally, dark-brown, almost black ; internally, a yellowish-white ; the odor is feeble and dis- agreeable, and the taste bitter, and somewhat astringent, leaving a slight sense of acrimony. The root partially yields its virtues to boiling water, but wholly to alcohol or ether. The root contains a resin, to whieh the name, Macrotin or Cimicifugin, has been applied, likewise gum, starch, sugar, wax, fatty matter, tannic and gallic acids, a black coloring matter, a green coloring matter, lignin, and salts of potassa, lime, magnesia, and iron. Properties sulphuric acid, it is converted into a kind of sugar, termed Glycocoll, or Sugar of Gelatin. The inferior kinds of isinglass are yellowish and more opake than the better kinds. Analysis has found in isinglass a large quantity of gelatin, some albumen, osmazome, inso- luble membrane in boiling water, free acid, various salts and water. An excellent cement, called Armenian or Diamond Cement is made with isinglass, which is valuble to the chemist and pharmaceutist for mending glass, china and porcelain vessels, which are not exposed to heat and moisture. It is made by sprinkling water upon two drachms Ilex Opaca. 555 of isinglass, allowing it to stand until softened, then adding as much proof spirit as will rather more than cover it, and dissolving it with a moderate heat. Have previously prepared, a solution made byr dissolv- ing one drachm of gum mastic, in two or three fluidrachms of alcohol. Mix the two solutions, and stir in one drachm of gum ammoniacum, previously reduced to a fine powder, and rubbed down with a little water. Evaporate, if necessary, in a water-bath to a proper consistence. Keep the cement thus prepared in a vial. When required for use plunge the bottle in warm water, and keep it there until the cement becomes fluid; then apply it Avith a stick or small hard brush to the edges of the broken vessel, previously warmed. Compress the pieces firmly together until cold, taking care to make the contact perfect, and using a very thin layer of cement; when properly applied, the cement is almost, if not quite, as strong as the glass or china itself. A cement for stoneware may be made by allowing gelatin to swell in cold water, the jelly warmed, and so much recently slaked lime added as is requisite to render the mass sufficiently thick for the purpose. A thin coating of this cement is spread Avhile warm over the gently heated surfaces of fracture of the articles, and let dry under a strong pressure. What oozes out is removed directly with a moist rag. Isinglass is sometimes kept cut up in fine shreds, in which form it is more readily acted on by boiling water. Properties and Uses.—Isinglass is seldom used in medicine except as a nutritive. It is used as a diet, in the form of jelly, or added to other jellies, to give them a tremulous appearance. I have used the following preparation in incontinence of urine, both in children and adults, in many instances, and have found it a useful as well as agreeable remedy, proving serviceable when other means had failed: Take of isinglass (long staple) one roll; boil it in one pint of water till it is dis- solved, then strain, add one pint of sweet milk, put it again over the fire, and remove it just as ebullition commences; then sweeten with loaf sugar, and grate nutmeg upon it. When made, it very much resembles custard. Of this, a tumblerful may be taken three or four times a day by an adult. Isinglass is employed in the arts for various purposes, and is often added to vegetable jellies for the purpose of giving them a tremulous appearance. Three drachms form a proper jelly with a pint of water. ILEX OPACA. American Holly. Nat. Ord.—Aquifoliaceaa. Sex. Syst.—Tetrandria Tetragynia. THE LEAVES. Description.—This tree rises from twenty to forty feet in hight, having leaves which are alternate, coriaceous, evergreen, smooth and shining, 556 Materia Medica. flat, oval, acute at the end, and the wavy margins armed with strong, scattered spiny teeth. The flowers are small, greenish-white, and are arranged in scattered clusters along the base of the young branches, and from the axils of the leaves. The calyx is persistent; calyx-teeth, acute. The corolla is rotate, monopetalous, four-cleft; stamens erect, and alternate with the divisions. The ovary is globular, four-celled, with four sessile stigmas. The fruit is globular, umbilicated at top, fleshy, scarlet, and contains four bony nucules. History.—The Holly is found growing throughout the United States from Maine to Louisiana, in moist woodlands, and flowering in June. It is quite common to the Atlantic States, especially New Jersey. The leaves are the medicinal parts; they have a bitter, somewhat austere taste, but no odor, and yield their virtues to water or alcohol. They are said to contain ilicin, wax, gum, several salts, etc. Ilicin is the bitter principle upon which the febrifuge virtues of the leaves depend; it may be obtained by diluting a strong alcoholic extract of the holly leaves with water, to which add sugar of lead, then sulphuric acid, and finally carbonate of lime. The ilicin being thus separated, dissolve it in alco- hol ; then evaporate to a syrupy consistence. Or, a filtered decoction of the leaves may be boiled with animal charcoal, then allow the char- coal to subside, wash it, treat it with alcohol, filter off the alcoholic solution, and evaporate to a syrupy consistence. The liquid thus obtained is very bitter, and when allowed to evaporate spontaneously, yields an amorphous substance, resembling gelatin, which is ilicin. It is not soluble in ether, partially dissolves in warm water, soluble in alco- hol, and is not decomposed by acids or alkalies. Two pounds of the dried leaves yield more than two ounces of this principle. The inner bark of the holly is glutinous, and the viscous substance called birdlime is prepared from it, by burying it in the earth for some days, in order to soften it, it is then beaten in a mortar, and well washed in water to sepa- rate the impurities. The berries are about the size of a pea, red, with a bitter, acrid taste. Properties and Uses. — Holly leaves are tonic and febrifuge; said to be very efficacious in the treatment of intermittent fever, used in doses of a drachm of the powder two hours before the paroxysm. The infu- sion has likewise proved beneficial in catarrh, jaundice, pleurisy, small- pox, gout, etc. Ten or twelve of the berries, are said to be emeto- cathartic, producing copious watery evacuations. Ilicin, as well as the holly leaves, exerts a sedative influence on the spleen, liver, and pancreas, and is a cheap substitute for quinia. The dose of ilicin for an adult, as a febrifuge or antiperiodic, is twelve grains gradually increased to twenty-four, and given in the form of pill. The European Holly, Ilex Aquifolium, together with several other species in this country, possesses similar properties. The Hex Vomitoria Impatiens Pallida. 557 or South Sea tea, an evergreen shrub growing in our Southern States, is the Cassina of the Indians. They toast its leaves and make a decoc- tion, called Black drink, which is used in their religious ceremonies and great councils, by the men only, to purge their bodies from impurities. The leaves are inodorous, with an aromatic, acrid taste. A decoction of them in small doses, acts as a powerful diuretic; in large doses it pro- duces copious evacuations from the stomach, bowels, and bladder. The inhabitants of North Carolina, on the sea coast, modify the deleterious action of their brackish water, by boiling a few leaves of Cassina with it. These plants are deserving a careful investigation. IMPATIENS PALLIDA. Jewelweed. Nat. Ord.—Balsaminaceaa. Sex. Syst.—Pentandria Monogynia. THE HERB. Description.—Impatiens Pallida, likewise known by the names of Pale Touch-me-not, Balsam-weed, etc., is an indigenous annual plant, having a smooth, succulent, tender, subpellucid, branching stem, with tumid joints, and growing from two to four feet in hight. The leaves are oblong-ovate, coarsely and obtusely serrate, teeth mucronate, from two to five inches long, petiolate, and about two-thirds as wide. The flowers are large, pale-yellow, sparingly maculate, mostly in pairs; peduncles two to four-flowered, elongated. Sepals apparently but four, the two upper united, the lowest gibbous, dilated-conical, broader than long, with a very short, recurved spur. Petals apparently two, unequal-sided and two-lobed, each consisting of a pair united. Stamens five, short; anthers opening on the inner face, connivent over the stigma. Ovary five-celled; stigma sessile. Capsules oblong-cylindric, an inch long, five-valved, bursting at the slightest touch Avhen ripe and scattering the anatropous seeds. Impatiens Fulva, or Speckled Jewels is the most common variety; its leaves are rhombic-ovate, obtusish, coarsely and obtusely serrate, teeth mucronate. The flowers are smaller than in the previous one, deep orange, and maculate with many broAvn spots; lower gibbous sepals acutely conical, longer than broad, with an elongated, recurved spur. Impatiens Balsamina, the Garden Balsam or Ladies' Slippers, is spon- taneous about gardens ; its leaves are lanceolate, serrate, upper ones alternate; peduncles clustered, one flowered; spur shorter than the ' flowers. The flowers are red, white, purple, pink, flesh-color, and scar- let; sometimes they are double. This is an exotic plant, a native of the East Indies, and cultivated as a beautiful garden annual. Its hight is from one to five feet. 558 Materia Medica. History.—These plants grow throughout the United States, in moist shady places, and along rills, in rich soil, flowering from July to Sep- tember. The I. Pallida is most common northward and westward and the I. Fulva, southward. They all possess similar properties. The whole plants are used, and impart their virtues to water. Properties and Uses.—They are aperient and diuretic ; a decoction is recommended in jaundice, hepatitis and dropsy. The juice is said to remove warts, cure ringworms, salt-rheum, etc., and to cleanse foul ulcers ; or it may be applied for these purposes in the form of a poultice boiled in milk. The recent plant boiled in lard, forms an excellent oint- ment for piles. INULA HELENIUM. Elecampane. Nat. Ord.—Asteraceaa. Sex. Syst.—Syngenesia Superflua. THE ROOT. Description.—Elecampane has a thick, fusiform, branching, aromatic, and perennial root, with a thick, leafy, round, furrowed, solid stem, from four to six feet high, and branched and downy above. The leaves are large, ovate, serrated, veiny, smooth and of a dark-green color above, downy and hoary beneath with a fleshy midrib ; the radical ones are petiolated, from one to three feet in length, by six or twelve inches wide ; the cauline ones sessile, amplexicaul. The flower -heads are large, radiated, solitary at the downy summits of the branches, two inches broad, and of a bright-yellow color. The involucre is hemispherical; the order scales are broad, recurved, leafy, finely downy on both sides; the inner scales are narrow, linear, and chaffy. The florets of the ray are numerous, spreading, linear, ligulate, pistillate, and terminate in three unequal teeth; the disk-florets are numerous, perfect, tubular, five-cleft. The anthers are furnished with bristles at their base; the ovary is oblong with a filiform cloven style, and spreading, obtuse stig- mas. The seeds are quadrangular, smooth, striated, and furnished with a simple, roughish pappus. History.—Elecampane is a native of Europe and Japan, and is natu- ralized in some parts of the United States, growing in moist places, and . about houses, flowering in July and August. The root is the officinal part, and should be gathered in autumn, and in the second year of its growth. When fresh it is very thick, spindle-shaped, much branched, with whitish cylindrical ramifications furnished with thread-like fibers; brown externally, and whitish and fleshy internally. As found in the shops in the dried state, it is usually in longitudinal or transverse slices, and of a grayish color internally. It has an agreeably aromatic, some- what camphorous smell, and a warm, aromatic, bitter taste. It yields IODINUM. 559 its properties to alcohol or water, but more especially to the former. Analysis has found in it, a volatile oil, a peculiar camphor, wax, acrid resin, gum, bitter extractive, inulin, etc. Inulin is an amylaceous sub- stance, differing from starch in being deposited unchanged from its solution in boiling water, as the liquid cools, and in giving a yellowish instead of a blue color with iodine. Its constitution is identical with that of starch, and it has been found in the roots of many other plants. Beside this principle, elecampane contains another, called Helenin, which is intermediate in its properties between the essential oils and camphor, and is separable by distillation with water. Helenin may be obtained by cutting the fresh root of elecampane in slices, and exhausting with boiling alcohol of sp. gr. 0.833; the hot solution is to be filtered, and mixed with three or four times its bulk of cold water, when a slight turbidness results, and after standing twenty-four hours, long, dazzling white needles of pure helenin will be found in the li|uid, leaving very little in solution. The dried root gives a smaller quantity of this prin- ciple than the fresh. Inulin may be had by boiling the roots in water, and concentrating the decoction by evaporation ; it is deposited as a brittle white mass, formed of crystalline grains, or as a fine, tasteless powder. Properties and Uses.—Elecampane is an aromatic stimulant and tonic, and is said to possess diaphoretic, diuretic, expectorant, and emmena- gogue properties. It is much used in chronic pulmonary affections, weakness of the digestive organs, hepatic torpor, dyspepsia, and inter- nally and externally in tetter, itch, and other cutaneous diseases. When added to the Compound Syrup of Spikenard, it should be exhausted by boiling alcohol, and the tincture added to the syrup, instead of boiling it with the other articles, as is usually done. The alcoholic extract, com- bined with powdered extract of liquorice, benzoic acid, sanguinarina, and morphia, forms a lozenge or pill very valuable in chronic catarrhal, bronchial, and all pulmonary irritations; one drop of the Oil of Stillin- gia may be added to each lozenge, for bronchial and laryngeal affec- tions. Dose of the powder, from one scruple to one drachm ; of the infusion, from one to two fluidounces. Off. Prep.—Decoctum Helenii; Extractum Helenii Hydro-alcoholi- cum ; Syrupus Aralia Compositus. IODINUM. Iodine. Preparation.—Kelp, which contains about a*.224th part of Iodine, is lixiviated in water, in Avhich about one-half dissolves. The solution is concentrated to a pellicle, and allowed to cool, Avhereby7 all the salts, except the Iodide of Sodium, are almost completely separated, they 560 Materia Medica. being less soluble than the iodide. The remaining liquor, which is dense and dark-colored, is rendered sour by sulphuric acid, whereby carbonic acid, sulphureted hydrogen, and sulphurous acid are evolved, and sul- phur is deposited. The liquor is now introduced into a leaden still, and distilled Avith a portion of deutoxide of manganese into a series of glass receivers, inserted into one another, in which the iodine is condensed. In this process the iodide of sodium is decomposed, and the iodine evolved ; and the sulphuric acid, deutoxide of manganese, and sodium unite, so as to form the sulphate of protoxide of manganese and sulphate of soda. Souberain states that a much larger quantity of iodine may be obtained by the following process : Add sulphate of copper to the mother water so long as a Avhite precipitate of iodide of copper is thrown down. Then treat the supernatant liquid with more of the sulphate, together * with iron-filings. The iron, taking the place of the copper in the solu- tion, sets that metal free ; and the metal, in the act of evolution, unites with what remains of the iodine in the fluid, so that more iodide of copper is formed. When this iodide is mingled with oxide of manga- nese and sulphuric acid, a moderate heat decomposes it, and iodine is sublimed. History.—Iodine is an elementary non-metallic body, discovered in 1812 by Courtois, a French soda manufacturer; and in 1820, its medi- cinal virtues were first made known by Dr. Coindet, sen., of Geneva, It exists in many marine vegetables, particularly the fuci or common sea- Aveeds, and is also found in nitre, sponge, sea-water, oyster, cod-liver oil, water-cress, brook-lime, fine-leaved water hemlock, coal-gas, many ores, salt-springs, spring-waters, etc. Sea-weeds, however, contain it in the greatest proportion ; they are burned for the sake of their ashes, the product being a dark-colored fused mass called Kelp. Iodine is a soft, friable, opake substance, in the form of crystalline scales, or in solid masses, of a shining appearance, and bluish-black color. It emits a peculiar, powerful odor, which strongly irritates the nostrils, and excites cough, has a hot, acrid taste, and is brittle and pul- verizable. It stains the skin broAvnish-yellow, and if the contact be pro- longed, will destroy the soft textures of the body. It is volatile, and slowly evaporates at common temperatures ; when heated it evaporates more rapidly, fuses at 245°, and boils at 347°, distilling over in the form of a rich purple vapor, which condenses* into scales. Water dissolves only a 7,000th of its own weight of iodine, and acquires a brownish- yellow color; in saline solutions it is much more soluble, and freely so in solutions of chloride of sodium, nitrate of ammonia, or iodide of potassium. It dissolves in twelve parts of rectified spirit at 60°, is very soluble in ether, or the volatile oils, but with some of them, especially those from coniferous vegetables, considerable heat is evolved, brisk IODINUM. 561 effervescence ensues, and much of the iodine is discharged in vapor. It unites with oxygen or hydrogen to form acids; also with sulphur, phos- phorus, carbon, chlorine, etc.; starch globules, if converted by boiling with water into soluble starch or amidin, form a blue precipitate with it, of such intensity that iodine may be detected in 450,000 parts of water. To effect this the iodine must be free, which may be obtained by adding a little nitric acid to the suspected solutions, and the solutions must be cold. Iodine is easily mixed with fatty substances ; it is apt to escape from the surface of ointments, unless united with iodide of potassium, which much impedes this result. The combination of iodine with hydro- gen forms a gaseous acid, called Hydriodic Acid : and that with oxygen forms three acids, the Iodous, Iodic, and Hyperiodic Acids. Starch is a delicate test to determine the presence of iodine in urine, solutions, etc. Chloroform has been recently proposed as a test; thus, if 150 grains of a solution containing one part of iodide of potassium in one hundred thousand of its weight, be treated with two drops of nitric and fifteen or twenty drops of sulphuric acid, and afterward shaken with fifteen grains of chloroform, the latter acquires a distinct violet tint. Chloroform may also be applied to the detection of iodine in the several varieties of cod-liver oil, the amount of which may be judged by the depth of color produced ; as follows : Incinerate in an iron spoon 50 parts of the speci- men of the oil with 5 of caustic potassa, dissolved in 15 of water, and exhaust the cinder with the smallest possible quantity of water. Filter the solution, acidulate it with nitric and sulphuric acids, and agitate with four parts of chloroform. After a time, the chloroform is deposited of a violet color, more or less deep according to the amount of iodine pre- sent. This test of iodine was presented by M. Rabourdin. Dr. A. Overbeck gives the following very delicate test for iodine : Some starch or sugar is poured into a test-tube with concentrated nitric acid, and heated over a spirit-lamp very gently7 until a violent evolution of gas ensues. The spirit-lamp is then removed, and the gas, which now evolves without a continuation of the application of heat, is conducted into the fluid to be tested, to which a solution of starch has been added. If the fluid contains only a millionth of iodide of potassium, a blue coloration directly results. By a farther introduction of the gas, the iodide of starch precipitates out in flocks, and deposits itself, when at rest, as a compact, massy precipitate. In this way he found iodine in many plants, particularly in the ashes of several ranunculuses. There are so many substances incompatible with iodine, that its preparations are best given in simple water sweetened, and diluted to the patient's taste. Iodine is much subject to adulteration : oxide of manganese, char- coal, plumbago, red oxide of iron, and the like, are often fraudulently added to it. The most frequent adulteration, however, is water, which may be easily detected by the presence of visible moisture in the bottle, or by the iodine adhering to the inside of it. The Edinburgh College 36 562 Materia Medica. has given a test which detects all impurity beyond two per cent. It is based upon the fact that pure iodine diffused in water, forms a colorless solution of iodide of calcium and iodate of lime, with a certain propor- tion of quicklime. Accordingly, an amount of quicklime is directed, which is not quite sufficient to form a colorless solution with iodine, con- taining only two per cent, of impurity; and hence, if the sample con- tain more impurity, the lime is competent to produce a solution without color. The test is : Thirty-nine grains of the iodine suspected, with nine grains of quicklime, and three ounces of water, when heated short of ebullition, slowly form a perfect solution, which is yellowish or brownish if the iodine be pure, but colorless if there be above two per cent, of water or other impurity. Properties and Uses.—In large doses, Iodine is an irritant and corro- sive poison, stimulating the mucous membranes, liver, and absorbent glands, exciting the sexual organs, and producing debility of the diges- tive functions, muscular weakness, and emaciation. This influence upon the system, in which its poisonous effects are developed, is termed Iodism. Its symptoms are restlessness, palpitation, a sense of constric- tion in the throat, and of burning along the gullet, excessive thirst, pain and nausea in the stomach, vomiting and purging, severe cramps, diu- resis, priapism, rapid and extreme emaciation, and frequent pulse. From four to six grains have produced these symptoms, hence it should never be administered in large doses, and Avhen these effects appear, the medi- cine should at once be stopped. In small or medicinal doses, it is a stimulant, tonic, alterative, diu- retic, emmenagogue, and diaphoretic. It affects especially the absorb- ent and glandular systems, and its results vary according to the dose, combination, etc.; it has been detected in the urine soon after being swallowed, also in the saliva, perspiration, milk, and blood, and always in the form of hyuriodic acid, or an iodide. It is supposed to undergo conversion in the stomach into hydriodic acid, and thus absorbed. Iodine and some of its preparations will occasionally produce salivation, soreness of the mouth, coryza, and often pustular eruptions. Under its influence, enlarged glands are brought to their normal size, and stru- mous ulcers gradually healed. Occasionally it has caused a rapid and permanent wasting away of the mamma or testicles ; and again after a lapse of time, these organs have recovered their original development. It is employed medicinally in various forms of disease, in some of which it produces astonishingly beneficial results. The diseases in which it appears to be more generally efficacious, are bronchocele, glandular obstructions, scrofula, syphilis, mercurio-syphilis, strumous ophthalmia, ozcena, ulcers of the integuments, enlargement of the external absorbent glands, chronic enlargement of the liver and spleen, mamma, testes, and uterus, ovarian tumors, leucorrhea, amenorrhea, dysmenorrhea, caries, paralysis, chorea, rheumatism, and in fact all diseases of a hyper- IODINUM. 563 trophical, strumous or cachectic character. In bronchocele it is most serviceable in the early congestive stage, or in the middle stage of gelatiniform effusion; in the indurated stage of the thyroid gland, it is of little benefit. In this affection its use should be continued uninter- ruptedly, for at least five weeks, and if no good effects appear, it may be laid aside. It should always be combined with some narcotic, to lessen or prevent its irritant results. The tincture diluted with three times its volume of water, has been recommended as an injection in hydrocele, after removal of the effused fluid, to stimulate the tunica vaginalis, to adhesive inflammation. In erysipelatous inflammations it has been advised to paint the inflamed surface with a strong tincture ; likewise in chilblains, and cutaneous scrofula. Iodine is not a cumu- lative medicine, like lead, digitalis, etc., hence, whenever its effects approach iodism, a suspension of its use will gradually remove them; however, at the present time, these effects are not so often observed as among its early investigators. Yet, as some persons are very suscep- tible to its influence, the approach of iodism should be carefully watched, and its symptoms checked. In chronic diarrhea and dysentery, cholera- infantum, colliquative diarrhea of phthisis and scrofulous diseases, I have found the following a superior remedy. Take of iodine one and a half grains, sulphate of morphia one-eighth of a grain, geraniin twenty grains—triturate thoroughly together in a mortar, form into a pill mass with simple syrup, or extract of liquorice, and divide into ten pills ; of these, one pill may be given every hour or two to an adult. In hepatic and splenitic affections, leptandrin may be substituted for the geraniin. In the Mexican diarrhea I succeeded in curing every case in which the folloAving preparation was employed : Take of iodine one and a half grains, tannic acid ten grains, distilled water five fluidrachms ; mix together. For an adult, give one fluidrachm, every two hours in syrup of ginger, or cinnamon water; to be continued daily. Externally, iodine is used in the form of ointment for strumous ulcers, ophthalmia, and some cutaneous diseases. A caustic iodine is recommended as an application to stimulate or destroy soft and fungous granulations, and as a remedy for noli-me-tangere; it is made by adding an ounce each of iodine and iodide of potassium, to two ounces of distilled Avater. Iodine is contra-indicated in cerebral congestion, and tendency to apoplexy, in menorrhagia, in disordered stomach or bowels, or wherever local dis- eases become attended with symptomatic fever, or with incidental febrile affections. Iodine may be kept in a state of solution when added to mixtures in the form of tincture, by the addition of syrup of orange peel, or a few grains of tannic acid. When given internally to females it is apt to increase the quantity of the menstrual discharge, and sometimes to multiply the periods of its appearance; if the symptoms are not very severe or alarming but little interference will be required, as they will 564 Materia Medica. cease after a short time; where this is demanded, a cessation of the use of the remedy will most generally suffice. In the employment of iodine, if the urine is passed in quantity, and on examination is found to con- tain iodine, and the strength and appetite of the patient gradually return, it may be considered indicative of a beneficial therapeutical influence, and its use should be continued. Dose of iodine in substance, half a grain, two or three times a day, in pill form; of the tincture from five to fifteen drops, twice a day. The best forms for internal use are the Compound Tincture, and Compound Solution. When given in powder, it should be united with opium, and formed into a pill with extract of liquorice. In poisoning by iodine, first evacuate the stomach, by giving an emetic in starch water, and afterward administer freely, starch water, or flour, or arrowroot in water. Off.

IPOM^EA JALAPA. Jalap. Nat. Ord.—Convolvulaceaa. Sex. Syst.—Pentandria Monogynia. THE ROOT. Description.—The root of Jalap is a roundish, somewhat pear-shaped tuber, externally blackish, internally white, with long fibers proceeding from its lower part, as well as from the upper root-stalks. The stems are several, roundish, smooth, herbaceous, of a reddish-brown color, much disposed to twist, and rising to a considerable hight upon neighbor- ing objects, about which it twines. The leaves are cordate, entire, smooth, conspicuously acuminate, deeply serrated at the base, the lower ones sometimes nearly hastate, or with diverging angular points, the under surface prominently veined, the petioles often nearly the length of the leaf. The peduncles about the length of the petioles, each one supporting two, rarely three flowers. The calyx is ebracteate, five- leaved, obtuse, with two of the divisions external. The corolla is fun- nel-form, of a lilac-purple color. Stamens five; anthers oblong, white, somewhat exserted. Ovary slender, bilocular. Style slender; stigma simple and capitate. Seeds not known. History.—It is only within a few years that any certainty has existed in relation to the plant from which the jalap root was obtained. It was first spoken of in 1609, as Bryonia Mechoacana Nigricans, then it was regarded by Ray as Convolvulus Americanus, jalapium dictus, after which Tournefort, being misled by persons who stated that they had seen the plant growing, attributed it to a species of Mirabilis. Balfour placed IPOM^EA JALAPA. 565 it as the Exogonium Purga, and Linnaus named it Convolvulus Jalapa, and thus much difference of opinion existed, until in 1827, when Dr. J. R. Coxe of Philadelphia, having received roots of the true Jalap from South America, from which he succeeded in producing a perfect flower- ing plant, first made known to the scientific world its true character. The name of Ipomaia Purga was bestowed upon the plant by Hayne and Wenderoth, but as the American authorities have a claim prior to all others, it may be considered as settled that Ipomoea Jalapa, the name originally given to it by Nuttall, is looked upon as the officinal species. The Jalap plant is a native of Mexico, growing at a hight of about 6000 feet above the level of the ocean, near the city of Xalapa, in the state of Vera Cruz, from which city it is generally exported, and from which it also derives its name. It is usually imported in bags containing one or two hundred pounds. The root is the officinal part, and is gathered at all seasons, but principally in March and April, when the young shoots are appearing. The plant might be cultivated in the southern parts of the United States. When fresh, the root is black externally, white and milky within, and varies in size according to its age, from that of a walnut to that of a moderate-sized turnep. It is dried in net bags over the fire, sometimes entire, and sometimes in sections. It is imported in irregularly round or pear-shaped masses, seldom as large as the fist, and is either entire, or divided into longitudinal or transverse slices. It is ponderous, hard, dark- brown externally, rough and wrinkled, internally grayish diversified by irregular concentric darker circles, in which the substance is denser and harder than in the intervening spaces. If moist, it is tough; if dry, rather brittle, with a shining undulated fracture, exhibiting numerous resinous points, distinctly visible with the microscope. The odor of jalap is faint and disagreeable, but stronger on rubbing or powdering it, and the taste is nauseous and sweetish, succeeded by some acridity. It is often attacked by insects, but its actiA-e portion or resin is left untouched by them, rendering it, consequently, more energetic; worm-eaten jalap may be employed for procuring the resin, but should not be formed into powder, as it would be above the proper strength. Jalap is rather difficult to pulverize, but if triturated with cream of tartar, sugar of milk, or other hard salt, the process of pulverization is facilitated, and the powder rendered much finer. When in powder, the color is a pale grayish- brown, and if inhaled, it irritates the nostrils and throat, and provokes sneezing and coughing. Its solvents are water, alcohol, or spirits. Water takes up but a small portion of its cathartic principle, but con- siderable of an amylaceous and mucilaginous extractive matter. Alco- hol dissolves its resin, on which its cathartic virtues depend. Proof spirits or diluted alcohol completely extract its active properties. Analysis of the commercial jalap has detected in it, resin soluble in alcohol, a soft resin soluble in ether, also, colored gummy extract, starch, 566 Materia Medica. albumen, lignin, numerous salts, and uncrystallizable sugar. Jalap root is seldom adulterated; the best quality may be known by being com- pact, ponderous, dry, dark, with many shining lines and points; if light, whitish internally, spongy, friable, and of a dull fracture, it should be rejected. Several adulterations are spoken of by authors, but they can usually be detected without difficulty. The resin is more liable to be adulterated with guaiacum, resin and colophony, and which may be detected by sulphuric ether which does not dissolve pure jalap resin. Properties and Uses.—Jalap is an irritant and cathartic, operating briskly, producing copious liquid stools with griping, and sometimes ac- companied with nausea and vomiting. Large doses produce violent hypercatharsis, sometimes terminating fatally. When applied to a wound it is said to induce purgation. Notwithstanding its activity, it is a safe and convenient purgative, much in use among the profession, and is applicable in all cases where it is desirable to produce a powerful influence on the bowels, or to obtain copious evacuations. In intestinal inflammations it should not be used. United with the bitartrate of potassa, its hydragogue properties are much increased, and thus proves beneficial in dropsies, as well as in some forms of scrofula. It is stated that the aqueous extract of jalap, the root having been previously ex- hausted of its resin by alcohol, will exert no cathartic influence, but will operate as a powerful diuretic. Three grains of jalap taken an hour before each meal, act as a slight nauseant, destroying a desire for food among persons who are apt to eat too freely. If jalap is digested in ether, its nauseous taste and smell will be wholly removed, without lessening its cathartic power. A biscuit is sometimes made for those to whom it is extremely nauseous and disagreeable ; five drachms of jalap, thirty of sugar, and four ounces of flour, are made into fifteen biscuits after the usual mode ; one biscuit is a dose. The tendency of jalap to gripe and nauseate, may be obviated by adding to the dose a grain or two of camphor, or three grains of cloves. The dose of jalap in powder is from fifteen to thirty grains (the aqueous extract ought not to be used, except as a diuretic); of the tincture, from one to four fluidrachms; the resin, or alcoholic extract is given in from four to eight grain doses, being usually rubbed up with sugar, or in emulsion, for the purpose of lessening its disposition to produce painful irritation of the intestinal mucous membrane. As a hydragogue, two drachms of the bitartrate of potassa is added to ten or thirty grains of pulverized jalap. Off.

Syst.—Triandria Monogynia. THE RHIZOMA. Description.—Iris Versicolor is an indigenous plant, with a fleshy, horizontal, fibrous root or rhizoma. The stem is two or three feet in hight, terete, flexuous, round on one side, acute on the other, and fre- quently branched. The leaves are about a foot long, half an inch to an inch wide, ensiform, striated, erect, and sheathing at base. Bracts scarious. The flowers are from two to six in number, and usually blue or purple, though varying much in color. Peduncles are of different lengths, and flattened on the inside. Sepals spathulate, beardless, the border purple, and the claw variegated with green, yellow, and white, and veined with purple. Petals erect, varying in shape from spathulate to lanceolate, usually paler than the outer, entire or emarginate. Stig- mas three, petaloid, purple or violet, bifid, crenate, and more or less reflexed at the point. Stamens three, concealed under the stigmas, with oblong-linear anthers. Capsule three-celled, three-valved, and when ripe oblong, turgid, three-sided, with roundish angles. Seeds numerous, flat. History.—Blue Flag is found in all parts of the United States, growing in low wet places, in meadows, and on the borders of swamps, serving to adorn them with its large and beautiful flowers, which make their appearance in June. They afford a fine blue infusion, which serves as a test of acids and alkalies. The root is the officinal portion, it has a peculiar odor, augmented by rubbing, and a nauseous taste, imparting to the fauces a powerful sense of heat and acrimony. In appearance the root very much resembles that of the Acorus Calamus. Its active pro- perties are taken up by alcohol or ether, and its acrimony, as well as medicinal activity, is impaired by age. If cut when fresh into slices, dried at the temperature of about 100°, and then powdered and kept in bottles or tin cans excluded from the air and light, the root retains its virtues unimpaired for a long time. It contains mucilage, oil, and resin, from the former of which it derives diuretic properties, by decoction. The resin is of a light brown color, of a faint odor, and of a taste resem- bling that of the root; when perfectly freed from oil it is whitish y7ellow. Its therapeutical influences are not positively known. The oil possesses in a high degree the taste and smell of the root, and is the principle to which it owes its medicinal activity. The oleo-resin is obtained for medical purposes, under the name of Iridin. Properties and Uses.—This is one among our most valuable medicinal plants, and is employed almost exclusively by Eclectics. It has been termed the Mercury of Eclectic practice, in consequence of the many 568 Materia Medica. indications it is capable of fulfilling. It is cathartic, alterative, siala- gogue, vermifuge, and diuretic. In dropsy, it may be used alone in doses of ten grains of the powdered root every two hours, as a hydra- gogue, or it may be combined with corn snakeroot, Eryngium Yucce- folium. In anasarca and hydrothorax, the saturated tincture of the root, taken in teaspoonful doses, every two or three hours, until its hydragogue influence is obtained, will be found serviceable ; in some instances it may be combined with an equal quantity of the saturated tincture of Euphorbia Ipecacuanha. In scrofula, and syphilis, whether primary or secondary, it acts as a powerful and efficacious agent, and may be used alone, or combined Avith mandrake, poke, black-cohosh, and other alteratives. In chronic, hepatic, renal, and splenitic affections, five or ten grains of the powdered root, will be found very valuable. Equal parts of blue flag root, mandrake root, and prickly-ash bark, combined, and given in doses of ten grains every two or three hours, to fall short of catharsis, will act as a powerful alterative, frequently caus- ing a copious salivation without injury to the teeth or gums. In chronic rheumatism, mercurio-syphilis, dyspepsia, tapeworm, gonorrhea, leucor- rhea, dysmenorrhea, and constipation, it has been used with positive ad- vantage, either alone, or in combination with other agents. A writer says, " The root of the Blue Flag extends its influence through every part of the system in small doses and repeated at short intervals; it seems to act more particularly on the glandular system, exciting them to a discharge of their respective offices ; in large doses it evacuates and exhausts the system, acting on the liver, and the alimentary canal throughout." In Eclectic practice salivation is not, as a general rule, desired for the cure of disease, yet we have many articles which produce it, and often without the practitioner's being aware of the fact, and hence, when it does occur, the cry is at once raised that Eclectics use mercury. Sali- vation caused by vegetable agents may be known from that by mercury, by the absence of mercurial fetor, and no sponginess of the gums or loosening of the teeth. The dose of pulverized blue flag is from five to twenty grains; of the saturated tincture, from ten to sixty drops. In some persons, and when exhibited in large doses, it is apt to occasion much distressing nausea, with considerable prostration, these effects may be obviated or mitigated, by combining it with a few grains of capsicum or ginger, a grain of camphor, or four or five grains of caulophyllin. There are several species of Iris, as /. Virginica, I. Lacustris, etc., which probably possess similar properties, and which are often collected and mixed with the officinal article. The Iris Florenlina, or Floren- tine Orris, is said to be emetic, cathartic, and diuretic, but is seldom employed, except in the composition of tooth-powders, and to conceal an offensive breath. Off.

Preparation.—This is prepared in the same manner as Aletrin, but being an oleo-resin cannot be reduced to powder. I had the pleasure of calling the attention of the profession to this article in 1844, about the same time I introduced the podophyllin, (to remarks on which I refer the reader) and again in 1846. I have used it extensively and find it to be an invaluable medicine. It is now prepared by W. S. Mer- rell of Cincinnati, for the use of practitioners generally. It is soluble in alcohol, but insoluble in water. Properties and Uses.—This is cathartic, alterative, sialagogue, diuretic and anthelmintic. I have used it more or less extensively for several years in combination with the resin of podophyllum, and in the form of pill, for dropsy, primary and secondary syphilis, chronic visceral affec- tions, rheumatism, gonorrhea, and many female affections. It is not as nauseating, when given alone, as podophyllin, and requires rather larger doses. One grain triturated with ten grains of sugar, may be given in three-grain doses, every hour or two, until a cathartic effect is produced. I have long used the following as a sialagogue in those cases of glan- dular diseases which seemed to resist the action of other means, viz : equal parts of Iridin, Podophyllin, and Xanthoxylin, given in grain doses every hour or two until ptyalism was produced. By trituration with sugar or lactin, this combination becomes more active. Iridin is not as prompt in its effects as Podophyllin, although it may be substi- tuted for this in all instances ; and its alterative influence, though slowly developed and without any immediate appreciable effect, is yet positive and certain. For the last six years I have used it in preference to the Podophyllin, in uterine diseases conjoined Avith Cimicifugin. The usual dose of Iridin is from one-half of a grain to five grains. Physicians will occasionally meet with patients upon whom Podophyllin, even in small doses, exerts a powerful and long continued influence, sometimes not readily obviated; in such cases, Iridin seems to me to be more espe- cially indicated. The addition of capsicum or caulophyllin to iridin, mitigates any harshness of action which it may produce. A combination of Iridin, Podophyllin and Xanthoxylin, or Corydallia is a most powerful and certain remedy for syphilis, either primary or secondary, and will be found very useful in scrofula. Iridin three grains, leptandrin six grains, and bitartrate potassa twenty grains, made into one powder, forms a hydragogue cathartic of much value in some forms of dropsy. Iridin may be used in all cases where the root of the Iris is indicated. 570 Materia Medica. JANIPHA MANIHOT. Tapioca. Nat. Ord.—Euphorbiaceaa. Sex. Syst.—Moncecia Monadelphia. the fecula of the root. Description.—This is the Cassava plant of the West Indies, and the Mandioca or Tapioca of Brazil. It has a large, white, fleshy, oblong, tuberous root, often weighing thirty pounds, and full of a wheyish, ven- omous juice. The stems are white, crooked, brittle, jointed, pithy, usually six or seven feet high, and having a smooth, white bark; the branches are crooked, and have, on every side, near their tops, leaves which are irregularly placed on long terete petioles, broadly cordate in their outline, and divided nearly to their base into five, spreading, lan- ceolate, entire lobes, attenuated at both extremities, dark-green above, pale glaucous beneath ; the midrib strong, prominent and yellowish-red below, with several oblique veins, connected by lesser transverse ones, branching from it. Stipules small, lanceolate, acuminate, caducous. The flowers are in axillary and terminal racemes. Pedicels with small, subulate bracts at their base. Male flowers smaller than the female. Calyx campanulate, divided into five spreading segments, purplish exter- nally, fulvous-brown within. Disk orange-colored, fleshy, annular, ten- rayed. Stamens ten, alternating with the lobes of the disk Filaments shorter than the calyx, white, filiform, free. Anthers yellow, linear- oblong. Female flower of the same color as the male, deeply five-parted, the segments lanceolate-ovate, spreading. Disk an annular, orange- colored ring, in which the purple, ovate, furrowed ovary is imbedded; style short; stigmas three, reflexed, furrowed and plaited, white. Cap- sule ovate, three-cornered, tricoccous. Seeds elliptical, black, shining with a thick fleshy funiculus. History.—This plant, formerly designated by botanists as the Jatropha Manihot, until separated by Kunth, is a native of South America, and is cultivated extensively in many parts of it, for the sake of its root, which serves as an article of food. The plant grows rapidly, and the root matures in about eight months. There are two varieties of the plant; the root of one variety is fusiform, brown externally, not exceeding six ounces in weight, Avith a sweet, amylaceous taste, and which may be eaten with impunity. This is termed Sweet Cassava. The root of the other and more common variety, is much larger, knotty, and black externally, abounds in an acrid milky juice, has a bitter taste, and is a deadly narcotic poison in the recent state. This is called Bitter Cassava, and its poisonous properties are said to be owing to the presence of hydrocyanic acid. Both varieties abound in starch. Tapioca is prepared from the Bitter Cassava. The root, which is very large, white, fleshy and tuberous, is reduced to a pulp, this is washed with cold water in Jeffersonia Diphylla. 571 funnel-shaped mat-filters, the starch is allowed to subside in the milky fluid which passes through, and is then elutriated in the usual manner, and finally converted into the granular form by drying it on hot plates. Should any of the volatile poisonous principle remain in the meal pre- vious to drying it, the heat employed for this purpose entirely removes it. Tapioca is a very pure starch, in the form of irregular Avarty grains, seldom larger than a pea, white, tasteless and inodorous. Boiling water dissolves it almost entirely,—or, if in small proportion to the tapioca, it forms with it a translucent, tasteless jelly, and firmer than is made with most varieties of starch. Cold water partially dissolves it, forming a liquid which yields a blue precipitate with iodine. Under the microscope it is found to consist of aggregated starch-globules, about the two thou- sandth of an im;h in diameter, partly broken, partly entire, the broken ones only being soluble in cold water, more uniform than the granules of most other varieties of fecula, with a distinct hilum which is surrounded by rings, and cracks in a stellate manner. The rupture observed in some of the granules, is owing to the heat employed in drying. Properties and Uses.—Nutritive and demulcent. Used as a light and agreeable nourishment for the sick ; it makes an excellent nourishment for infants about the time of Aveaning, and is less apt to turn sour on their stomach, than any other kind of farinaceous food. For the sick and convalescent, lemon juice and sugar form agreeable additions ; and in low states of disease, or debility, it may be improved by the addition of wine, nutmeg, or other aromatic. JEFFERSONIA DIPHYLLA. Twinleaf. Nat. Ord.—Berberidaceaa. Sex. Syst.—Octandria Monogynia. THE ROOT. Description.—This is an indigenous, perennial plant, sometimes known as Ground-squirrel Pea, and Rheumatism Root. The rhizoma is horizontal, with matted fibrous radicles ; the scape or stem is simple, naked, one- floAvered, and from eight to fourteen inches in hight. The leaves are in pairs, binate, placed base to base, oval, broader than long, ending in an obtuse point, smooth, glaucous beneath, and on petioles as long as the scape, which arise from the rhizoma. The flowers are large, regular, white. The calyx consists of four, colored, deciduous sepals. The corolla has eight flat, oblong, spreading, incurved petals. The stamens are eight, with oblong-linear anthers on slender filaments. Ovary ovoid, soon gibbous, pointed; stigma two-lobed. The capsule is obovate, or somewhat pear-shaped, stipitate, one-celled, opening half-way round horizontally, making a persistent lid. Seeds many on the lateral pla- centa, with a fleshy lacerate aril on one side, oblong. 572 Materia Medica. History.—This plant is found from New York to Maryland and Vir- ginia, and in many parts of the Western States, growing in limestone soil, in woods, and near streams and rivers, flowering in April and May. The root is the officinal part, it is yellow like the Hydrastis, but much larger, it has a pungent, nauseous, bitterish, and acrid taste, and an odor resembling Podophyllum. Water or alcohol extracts its virtues. It has not been analyzed. Properties and Uses. — Diuretic, alterative, antispasmodic, and a stimulating diaphoretic. Successfully used in chronic rheumatism, secondary or mercurio-syphilis, syphilitic pains, dropsy, in many ner- vous affections, spasms, cramps, nervous excitability, and even during pregnancy. In syphilitic diseases it is combined with corydallis. As a gargle it has been beneficial in diseases of the throat, ulcers about the fauces, scarlatina, ophthalmia, and indolent ulcers. It is administered in decoction and saturated tincture. Dose of the decoction, from two to four fluidounces, three times a day; of the tincture, from one to three fluidrachms, three times a day. Off.

Description.—This tree, also known as White Walnut, Oil Nut, etc., is indigenous, and grows to a hight of from thirty to fifty feet, with a trunk three or four feet in diameter at the distance of five feet from the ground. At a short distance from the ground, the stem divides into numerous, nearly horizontal, wide-spreading branches, covered with a smooth, gray bark, and forming a large tufted head, giving to the tree a peculiar appearance. The leaves are alternate, from twelve to twenty inches long, and consist of seven or eight pairs of leaflets, which are two or three inches in length, oblong-lanceolate, rounded at the base, acu- minate, finely serrate and downy, the petioles and branchlets downy with clammy hairs. The male and female flowers are distinct upon the same tree. The former are in large aments, four or five inches long, hanging from the sides of the last year's shoots, near their extremities. The scales which compose them are oblong and deeply-cleft on each side into about three teeth or segments. The anthers are about eight or ten in number, oblong and nearly sessile. The fertile flowers grow in a short spike at the end of the new shoot; they are sessile, and universally pubescent and viscid; when fully grown, they seem to consist of a large oblong ovary and a forked feathery style. The top of the ovary, how- ever, presents an obscurely four-toothed calyx. Within this is a corolla of four narrow lanceolate petals growing to the sides of the style; the JUGLANS ClNEREA. 573 style divides into two large, diverging, feathery, rose-colored stigmas nearly as long as the ovary. The fruit is sometimes single, suspended by a thin pliable peduncle; sometimes several are together on the sides and extremity of the same peduncle, of a green color, brown when ripe, oblong-oval, obtusely-pointed, hairy, and extremely viscid. The nut or nucleus is of a dark color, hard, oblong, pointed, carinated on both sides, its whole surface roughened by deep indentures and sharp prominences. The kernel is oily, pleasant-flavored, and edible. Juglans Nigra, or Black Walnut, grows from sixty to ninety feet high, with a diameter of from three to six feet,':with a brown bark. The leaf- lets are numerous, seven to ten or eleven pairs, ovate-lanceolate, serrate, subcordate at base, taper-pointed at the 'apex, smooth above, the lower surface and the petioles minutely downy. The fruit is globose, with scabrous punctures, the nut corrugated, and its kernel sweet, more plea- sant-tasted and less oily than the butternut, but greatly inferior to the European walnut, Juglans Regia. History.—These trees are common to North America. The J. Cinerea is found in Canada, and throughout the whole northern, eastern, and western sections of the United States, in rich woods, on elevated river- banks, and on cold, uneven rocky soils, flowering in April and May, and ripening its fruit in September. The tree, if tapped just before the unfolding of the leaves, yields a richly-saccharine juice, from which sugar may be obtained, nearly if not quite equal to that from the sugar- maple. The wood is light, of a reddish hue, but on account of its durability and exemption from the attacks of worms, is considerably used in panneling and ornamental work. The fruit, when quite young, is made into pickles, and the bark is employed for dying wool a dark- brown color, though inferior for this purpose to that of the black walnut. In the recent state it is acrid, and when applied to the skin, produces a rubefacient effect. The inner bark is the medicinal portion, especially of the root, and should be collected in May or June. When first uncov- ered on the tree, the inner bark is pure Avhite, but soon becomes a lemon, and ultimately a deep-broAvn color; it is of a fibrous texture, a slight odor, and a peculiar, bitter, subacrid taste. Boiling water com- pletely extracts its medical virtues. No satisfactory analysis of the inner bark of this tree has been made. The J. Nigra is rarely found in the Northern States, but is more com- mon to the Middle and Western. It flowers and ripens its fruit at the same time with the butternut. The duramen of its wood is compact and heavy, of a deep violet-color, surrounded with a white alburnum. It is extensively used in building, and for cabinet-work. Properties and Uses.—Butternut is a pleasant and mild cathartic, operating Avithout pain, irritation, or subsequent debility of the alimen- tary canal, somewhat of the cathartic character of rhubarb, but without 574 Materia Medica. inducing constipation after its action. It is especially adapted to cases of habitual constipation, dysentery, and other affections of the bowels. It is generally used in the form of an extract, in doses of from ten to thirty grains. A strong decoction of it is much employed in some sec- tions of the country, as a domestic remedy in intermittent and remittent fevers, as well as in other diseases attended with congestion of the abdominal viscera; it is also reputed efficacious in murrain of cattle and yellow-water in horses. The juice of the rind of the black walnut (Juglans Nigra) is said to remove ringworm and tetter; and a decoction has been used as a vermifuge. Its bark is acrid and styptic, seldom used except for tinctorial purposes. The European walnut (Juglans Regia) has recently been found by Professor Negrier, of Angers, in the highest degree efficacious in scrofula. He gave to children a teacupful of a strong infusion of the leaves, or six grains of the aqueous extract, or an equivalent dose of a syrup prepared from it two to four times a day; if there were ulcers or sore eyes, a strong decoction was applied to them. No injury was ever experienced from a long-continued use of the remedy. It appears to act as a moderately aromatic bitter and astringent. The above American species would probably ansAver as good a purpose. Juglandin is the name of an agent just prepared from the J. Cinerea, by Mr. W. S. Merrell. It is of a jet-black color, brittle like starch, with the peculiar odor of the bark, and a bitter, somewhat pun- gent and aromatic taste, with a stimulant effect on the fauces. It is insoluble in water, but becomes soluble on the addition of ammonia or liquor potassa; and the addition of acids to the solution precipitates the juglandin. Sulphate of iron added to water containing juglandin, dark- ens it. It is nearly soluble in alcohol, more so on the addition of ammo- nia ; partially soluble in ether. Muriatic acid turns a thin layer of it green; sulphuric acid, reddish-black; and with nitric acid it effervesces, and becomes yellowish-red. So far as employed, this article has answered an admirable purpose as a laxative and cathartic, in doses of from one to five grains; and will, probably, prove an invaluable agent. It is prepared by adding a saturated tincture of the bark of butternut to twice its volume of water, and distilling off the alcohol; the juglandin is precipitated in the water, from which it must be removed and dried. Combined with Castile soap it operates more promptly. Off. Prep.—Extractum Juglandis. JUNIPERUS COMMUNIS. Juniper. Nat. Ord.—Pinaceaa. Sex. Syst.—Dioecia Monadelphia. THE FRUIT OR BERRIES. Description.—This is an erect, evergreen shrub, generally small, but occasionally attaining a hight of twelve or fifteen feet, with numerous, Juniperus Communis. 575 very close branches, the extremities of which are smooth and angular. The leaves are attached to the stem or branches in threes, in a verticil- late manner, linear-acerose, sharply mucronate, entire, shining-green on their lower surface, channeled and glaucous along the center of their upper surface; they are always resupinate, and turn their upper surface toward the ground. The flowers are dicecious, the males in small axil- lary aments, with roundish, acute, stipitate scales, inclosing several anthers. Female flowers are on a separate shrub, having a small, three- parted involucre growing to the scales, which are three in number. The fruit is fleshy, roundish-oblong, berried, of a dark-purplish color, formed of the confluent succulent scales, marked with three prominences or vesicles at top, ripening the second year from the flower, and containing three seeds. History.—The Juniper is a native of Europe, though naturalized in some parts of this country, growing in dry woods and hills, and flower- ing in May. The fruit, or berries, as they are generally called, are the officinal parts; those which are imported from the south of Europe are the best.—the American berries are greatly inferior in strength, and not much used. They are globular, more or less shriveled, about the size of a pea, marked with three furrows at the summit, covered with a glaucous bloom, beneath which they are of a shining, blackish-purple color, and containing a brownish-yellow pulp, and three angular seeds. They haA7e an agreeable, aromatic odor, and a sweetish, warm, bitter, slightly terebinthinate taste, which properties they owe to an essential oil, the oil of juniper, which is obtained by distillation. The berries impart their virtues to water or alcohol. Beside volatile oil, they con- tain resin, gum, wax, sugar, lignin, water, and various saline sub- stances. Properties and, Uses.—Both the berries and oil are gently stimulant, carminative, and diuretic. The oil is said to act like copaiba in arresting mucous discharges, especially from the urethra. It is contained in the spirituous liquor called Hollands, one of its best forms as a diuretic. Five minims of the oil, with one fluidrachm of nitrous ether, given three times a day in any common vehicle, produces diuresis in dropsy Avhen other means fail. The berries are used principally as an adjuvant to more powerful diuretics. They have also been recommended in scor- butic and cutaneous diseases, catarrh of the bladder, and atonic condi- tions of the uterus and alimentary canal. Dose of the berries, from one to two drachms; of the oil, from four to six minims. Off. Prep. — Pilula Saponi Composita; Tinctura Pinus Pendula Composita. 576 Materia Medica. JUNIPERUS SABINA. Savin. Nat. Ord.—Pinaceaa. Sex. Syst.—Dioacia Monadelphia. THE TOPS AND LEAVES. Description.—Juniperus Sabina, is an evergreen, very compact shrub, growing from three to fifteen feet in hight, with a disposition to spread horizontally rather than to form a stem. The branches are slender, round, tough, the bark of the young branches light-green, that of the trunk rough and reddish brown. The leaves closely invest the younger branches, are numerous, small, erect, firm, smooth, pointed, of a dark- green color, glandular in the middle, opposite, and imbricated in four rows. The flowers are male and female on different trees. The fruit is a deep bluish-purple, almost black, about the size of a currant, of an ovoid shape, marked Avith tubercles, the remains of the calyx and petals, and containing three seeds. History.—This plant is a native of southern Europe, and is said to grow wild around our north-western lakes. The extremities of the branches and leaves are the officinal parts. When dried they fade very much in color; they have a strong, peculiar, rather unpleasant odor, especially Avhen bruised, and a disagreeable, bitter, resinous, acrid taste. They impart their virtues to Avater or alcohol. Their properties are owing to an essential oil, oil of Savin, Avhich is obtained by distillation; it is limpid and colorless. They are also said to contain gum, tannic or gallic acid, resin, chlorophylle, fixed oil, bitter extractive, lime, and salts of potassa. Properties and Uses.—Emmenagogue, diuretic, diaphoretic, anthel- mintic, and abortive. In over-doses it will produce gastro-enteritis. Useful in menorrhagia, and said to be beneficial in preventing threatened abortion. Care must be taken in its administration, as it may produce fatal results. It should never be given Avhen much general or local inflammation exists, and it should never be used during pregnancy. Sometimes used for worms, with pink and senna. The oil (oleum sabince), given two or three times a day, in doses of from ten to fifteen drops on sugar, is said to produce abortion, and it is apt to violently affect the stomach and bowels, bringing life into extreme danger. It is sometimes combined with oils of tansy7, pennyroyal, and hemlock, as an emmenagogue and abortivant; dose, from two to four drops. Exter- nally, the leaves in the form of cerate, have been used as a stimulant to indolent ulcers, and to maintain a discharge from blistered surfaces; and mixed with an equal weight of verdigris, the powder has been used for destroying venereal warts. Dose of powdered leaves, from five to fifteen grains, three times a day ; of the infusion, from half a fluidounce to two fluidounces. Off.

Syst.—Dioacia Monadelphia. THE LEAVES AND EXCRESCENCES. Description. — Juniperus Virginiana is an evergreen tree of slow growth, seldom attaining a very large size, though sometimes rising forty or fifty feet in hight, with a stem twelve or thirteen inches in diameter, straight and decreasing rapidly from the ground, giving off many hori- zontal branches; its surface generally unequal, and disfigured by knots, and the crevices and protuberances they occasion. The small twigs are covered with minute, densely imbricated leaves. These leaves are fleshy, ovate, concave, rigidly acute, with a small depressed gland on the mid- dle of their outer side, growing in pairs which are united at the base to each other, and to the pairs above and below them. (A singular variety sometimes appears in the young shoots, especially those which issue from the base of the trees; this consists in an elongation of the leaves to five or six times their usual length, while they become spreading, acerose, remote from each other, and irregular in their insertion, being either opposite or ternate; such shoots are so dissimilar to the parent tree that they have repeatedly been mistaken for individuals of a differ- ent species.) The barren flowers grow in small oblong aments, formed by peltate scales with the anthers concealed within them. The fertile flowers have a proper perianth, which coalesces with the germ, and forms a small, roundish berry, with two or three seeds, covered on its outer surface with a bright blue powder. History.—The Red Cedar grows in all latitudes of the United States, from that of Burlington, Vermont, to the Gulf of Mexico; it inhabits dry rocky situations, and is most abundant and vigorous in the southern States and maritime parts, and flowers in April and May. The interior wood is of a reddish color, fine-grained and compact, very light and durable, and is much used for tubs, pails, lead pencils, fences, etc. The tops and leaves are the officinal parts ; they have a peculiar, not un- pleasant odor, and a strong, bitterish, somewhat pungent taste. Their virtues reside chiefly in an essential oil, and are readily imparted to alco- hol. The leaves bear a close resemblance to those of the Juniperus Sabina, for which they are often but incorrectly employed, and from which they can be distinguished only by the difference of odor. Analy- sis has found in them volatile oil, gum, tannic acid, albumen, bitter extractive, resin, chlorophylle, fixed oil, lime and lignin. Excrescences are often found on the small branches, known as Cedar Apples, and produced, like galls, by the puncture of an insect; they have a some- what aromatic odor, and a bitterish taste. These are sometimes pow- dered, and administered successfully as a vermifuge, in doses of from ten to twenty grains, three times a day, in some convenient vehicle. 37 578 Materia Medica. Properties and Uses.—Same as the Juniperus Sabina, but less ener- getic, and used in the same diseases; also in scalding of urine, and derangement of the kidneys and bladder, with spearmint and marsh- malloAvs. The oil makes a valuable external stimulating application for rheumatic pains, bruises, etc. Dose of the leaves, from one to two drachms; of the oil, from ten to fifteen drops. The excrescences or cedar apples, as they are called, which are some- times found on the tree, are decided anthelmintics. The folloAving makes a pleasant and excellent vermifuge and tonic, for pale, sickly children; I have used it with much success in hundreds of cases: Take of cedar apples one pound; of black alder berries, (Prinos Verticillatus) one pint by measure ; digest these for fourteen days, in one quart of alcohol, and one pint of molasses. The more recent the articles, the better. Dose, one fluidrachm, three times a day, for a child one or two years old ; it is laxative, tonic and vermifuge. Off. Prep. —Linimentum Olei.

Description.—This plant is known by various names in different sec- tions of the country, as Laurel, Lambkill, Ivy, Big-leaved Ivy, Spoon- wood, Calico-bush, Mountain Laurel, etc. It is a beautiful shrub, from four to eight feet high, sometimes attaining the hight of a small tree; usually with very crooked stems, covered with a light-colored rough bark. The leaves are irregularly alternate and ternate, evergreen, coria- ceous, very smooth, with the under side someAvhat paler, ovate-lanceo- late, acute at each end, entire, on long petioles at the ends of the branches, and from two to three inches long. The flowers are numerous, white or variously tinged with red, very showy, clammy, and are dis- posed in splendid terminal, viscid-pubescent, simple or compound corymbs, with opposite branches. Pedicels glutinous, pubescent, with ovate, acu- minate bracts. Calyx small, five-parted, persistent, with oval acute segments. Corolla large, monopetalous, with a conical tube, a cyathiform limb, and an erect, shallowy five-lobed margin; at the circumference of the limb, on the inside, are ten niches or pits, accompanied with corre- sponding prominences on the outside; in these depressions the anthers are found lodged at the time Avhen the flower expands. The stamens are ten, hypogynous, bent outwardly so as to lodge their anthers in the niches of the corolla, but liberating them during the period of flower- ing and striking against the sides of the stigma; anthers two-celled, with two terminal pores. The ovary is roundish, supporting a slender, Kalmia Latifolia. 579 declinate style longer than the corolla; stigma obtuse. Fruit a dry cap- sule, which is roundish, depressed, five-celled, five-valved, the valves alternating with the divisions of the calyx. The seeds are numerous and minute. History.—Sheep-Laurel is found in most parts of the United States, on rocky hills andmountains, and in damp soil, sometimes forming dense thick- ets, with a profusion of beautiful rose-colored flowers which appear in June and July, forming a contrast with its dark shining green leaves. The leaves have poisonous narcotic properties, and prove fatal to sheep and some other animals, while goats, deer and partridges feed upon them with impunity. Where partridges which have fed upon them, have been eaten, it is said to have caused nausea, temporary blindness, pain in the head, dyspnoea, pallid countenance, cold extremities, feeble pulse, and even death. An emetic of mustard with warm water, has relieved some of the above symptoms, by removing the poison from the stomach. It is very doubtful, however, whether these symptoms were caused by the poisoned flesh of the birds, as numerous persons eat partridges that have been feeding on the laurel, without the least inconvenience. The pre- sumption is that the poisonous character of the flesh was caused by a peculiar state of animal decomposition. The Indians are said to use the expressed juice of the leaves, or a strong decoction, for the purpose of committing suicide. The leaves are the officinal parts, and yield their virtues to alcohol or water. They contain gum, tannic acid, resin, chlo- rophylle, fatty matter, a substance resembling mannite, an acrid prin- ciple, wax, extractive, albumen, yellow-coloring matter, lignin, and salts of potassa, lime, and iron. Properties and Uses.—In immoderate doses, Sheep-laurel is a poison- ous narcotic, producing vertigo, dimness of sight, great depression of the action of the heart, and cold extremities. In medicinal doses it is sedative, antisyphilitic, and astringent. Internally, either in powder, decoction, or tincture, it is an efficacious remedy in primary or secondary syphilis, and will likewise be found invaluable in febrile and inflamma- tory diseases, and hypertrophy of the heart, allaying all febrile and inflammatory action, and lessening the action of the heart. In active hemorrhages, diarrhea, and dysentery, it has been employed with excel- lent effect. I have extensively used this agent, and regard it as one of our most efficient agents in syphilis ; and have likewise found it very valuable in inflammatory fevers, jaundice, and ophthalmic neuralgia and inflammation. The remedy must always be used with prudence, and should any of the above-mentioned symptoms appear, the dose must be diminished, or its use suspended for a few days. In cases of poisoning by this article, stimulants, as brandy, whisky, etc., must be given, with counter-irritation to the spine and extremities. Sheep poisoned by eat- ing the leaves, have been saved by administering a gill or two of whisky to them. Externally, the fresh leaves stewed in lard, or the dried leaves 580 Materia Medica. in powder mixed with lard to form an ointment, are said to be beneficial in tinea-capitis, psora, and other cutaneous affections. Some time since I treated a case of syphilis of five weeks' standing, which had not received any kind of treatment during that period. The patient, at the time I saw him, had several chancres, the surface of the body and head was covered with small red pimples, elevated above a jaundiced skin, and he was in a very debilitated condition ; I administered a saturated tincture of the leaves of Kalmia, and touched the chancres with tincture of muriate of iron, and effected a cure in four weeks, removing the jaundice at the same time. The saturated tincture of the leaves is the best form of adminis- tration, it may be given in doses of from ten to twenty drops, every two or three hours; the decoction may be given in doses of from half a fluidounce to a fluidounce ; and of the powdered leaves from ten to thirty grains. There are other species of Kalmia, as K. Glauca or Swamp Laurel, and K. Angustifolia, or Narrow-leaved Laurel, which probably possess similar properties. Off.

Description.—For a long time the origin of Kino was unknown, but it has recently been ascertained to be the product of a lofty tree, growing upon the mountains of the Malabar coast of Hindostan, named Pterocar- pus Marsupium, belonging to the Natural Order Fabacea. It has an erect, very high trunk, rarely straight. The outer layer of bark is brown, spongy, falling off in flakes, and the inner is red, fibrous, and astringent. The branches are spreading, horizontal, numerous, extending far. The leaves are sub-bifarious, alternate, pinnate with an odd one, eight or nine inches long; leaflets five, six, or seven, alternate, elliptic, emarginate, firm, deep-green and shining above, less so below, from three to five inches long, and two or three broad. The petioles are round, smooth, waved from leaflet to leaflet, and five or six inches long; stipules none. Panicles terminal, very large; ramifications bifarious, like the leaves. Peduncles and pedicels round, a little downy. Bracts small, caducous, solitary below each division and sub-division of the panicle. Flowers very numerous, white, with a small tinge of yellow. Vexillum with a long slender claw, very broad ; sides reflexed, waved, curled, veined; keel two-petalled, adhering slightly for a little way near the middle, waved, etc., same as the vexillum. Stamens ten, united near the base, but soon dividing into two parcels of five each; anthers globose, two- lobed. Ovary oblong, pedicelled, hairy, generally two-celled; cells Kino. 681 transverse, and one-seeded. Style ascending. Legume on a long peti- ole, three-fourths orbicular, the upper remainder, which extends from the pedicel to the remains of the style, is straight, the whole surrounded with a waved, veiny, downy, membranous wing, swelled, rugose, and woody in the center, where the seed is lodged, not opening; generally one but sometimes two-celled. Seeds single, reniform. History.—Kino is the juice of the tree obtained by making longitudi- nal incisions in the bark ; it flows abundantly, and of a red color, and by drying it in the sun, it cracks into irregular angular masses, which are placed into wooden boxes for exportation. It sometimes comes to this country direct from the East Indies, but more generally from England. East India Kino, which is the ordinary kino of the shops, is usually in small, irregular, angular, shining fragments, in size between a pin's head and a pea, of a dark-reddish-brown or blackish color, opake, very brittle, easily pulverizable, and affording a reddish powder, much lighter colored than the drug in its aggregate state, and which becomes brownish on being kept for some time. It is inodorous, and of an intense, pure astringent, with barely perceptible bitterness, and leaving a sweetish after-taste in the mouth. It burns without fusion or softening, and with but little flame and frothing, leaving a scanty gray ash. Boiling water dissolves -a large proportion of it, forming when cold,, a permanent, intense blood-red solution ; and which yields, with sesquichloride of iron, a dark-green, coarsely flocculent precipitate, which is so abundant as to render the whole liquid pulpy. Acetate of lead affords a gray precipi- tate, and tartar emetic a gradually formed lake-red muddy jelly. Cold water forms with it a clear cherry-red solution, leaving a crumbly, gray- ish residuum. Alcohol dissolves about two-thirds of it, and forms a deep brownish-red tincture, which is not disturbed by water. By long stand- ing, the tincture gelatinizes, and loses its astringency. Proof spirit is a less complete solvent, but the tincture is less apt to gelatinize. Alkalies favor its solubility in water, but change its nature, and destroy its astrin- gency. When chewed, Kino softens in the mouth, slightly adheres to the teeth, and colors the saliva blood-red. It is found to contain 75 per cent, of tannin, and peculiar extractive, 24 of red gum, one of insoluble matter, and according to Buchner catechuin or catechuic acid. Its aqueous solution is incompatible with gelatin, the soluble salts of iron, silver, lead, antimony, bichloride of mercury, and the sulphuric, nitric and muriatic acids. There are many other exudations known in commerce as Kino, some of which are used principally for the purpose of adulterating the finer sorts; among the most important are the African Kino, Dhak-tree Kino, Botany Bay Kino, Jamaica Kino, and South American Kino. The African Kino, is at present very rarely seen in commerce ; from specimens sent home by Mungo Park during his last journey, it was 582 Materia Medica. decided an exudation from the Pterocarpus Erinaceus, a tree growing in Senega], and upon the banks of the Gambia, on the western coast of Africa. The Dhak-tree Kino is the product of the Butea Frondosa, a magnifi- cent leguminous tree of the East Indies. The juice naturally exudes from fissures in the branches of the tree, and concretes into red tears which become black under the action of the sun. They are irregularly angular, seldom so large as a grain of barley, apparently black and opake, but really of an intense garnet-red color, translucent in thin pieces, and frequently have fibers of bark adhering to one of their faces. Their taste is very astringent, brittle when chewed without adhering to the teeth, and tinge the saliva red. Their relations to water, alcohol, and other chemical reagents are very nearly similar to those of ordinary Kino. They contain from 73 to 90 per cent, of tannin. This Kino is much used in the arts in India, and would undoubtedly answer as well in medicine as the Kino of commerce. It is seldom imported into England, and never, at present, into this country. The Botany Bay Kino is the concrete juice of the Eucalyptus Resi- nifera, or Brown Gum tree of New Holland, a fine tall tree belonging to the Natural Order, Myrtaceae, and Sexual System, Icosandria Mono- gynia. When the bark of this tree is wounded, a red juice flows so profusely that sixty gallons may be collected from one tree. Mr. White states that five hundred pounds of Kino may be obtained in one year from a single tree. The juice concretes into a resinous-like substance, on the branches and trunk, which is at first reddish and translucent, but ultimately chocolate-colored and opake. It is in irregular masses, free from impurity, generally covered with a reddish powder from attrition, compact, very brittle, deep brownish-black, resinous in luster, and opake even in thin fragments. It is more bitter and less astringent than ordinary Kino, and tinges the saliva a dirty-lake red. It is easily powdered, the powder being of an umber color ; softens and swells up by heat, and burns with a dense flame or white smoke before it becomes perfectly charred. Cold water does not readily act upon it, slowly ac- quiring a pale-yellowish tint after an hour or two, with but little change in the appearance of the Kino ; boiling water dissolves considerable of it, forming a deep cherry-red solution, which, on cooling, precipitates a copious brick-colored deposit, if the solution be made with one part of the Kino to twenty-five of water. The remaining solution is yellowish- brown, and yields a deep-green turbid fluid with sesquichloride of iron, and a grayish-yellow precipitate with acetate of lead. Alcohol dissolves it in large proportion, forming a deep yellowish brown tincture. It is not so common in Europe as it was some years since, and is seldom seen in this country. Jamaica or West India Kino, is presumed to be the product of the Coccoloba Uvifera, or Sea-side grape, belonging to the Natural Order, Krameria Triandria. 583 Polygonacea, obtained by evaporating a decoction of the wood and bark. This tree grows in the West Indies and neighboring parts of the conti- nent. The evaporated fluid while in a semi-liquid state is poured into gourds, and allowed to harden. When removed from the gourd, it breaks into fragments of various sizes, having a tendency to the rectan- gular form, and about as large as a small cherry. Their consistence is uniform, their surface smooth and shining, and their color a very dark reddish-brown. They are not so shining nor so black as the common Kino; are opake in mass, translucent and ruby-red in thin fragments. They are readily fractured and pulverized, forming a dull-reddish pow- der, much paler than the commercial drug. They are inodorous, but very astringent and bitterish, very slightly adhering to the teeth when chewed, and coloring the saliva red. Cold water dissolves 89 per cent., and officinal alcohol 94 per cent. It contains about 41 per cent, of tannin. The South American, Columbia, or Caraccas Kino is probably de- rived from the Coccoloba Uvifera, which grows upon the continent as well as in the islands. It is imported in heavy masses, and closely re- sembles the Jamaica Kino, in color, luster, taste, and other properties, with the exception that it is nearly equally soluble in cold water and alcohol; without any adhesive matter to impede filtration in the aque- ous solution, and wanting a minute proportion of resinous matter. Properties and Uses. — Kino is a pure and energetic astringent, and may be used to fulfill all the indications for which catechu is employed. It is not considered so efficacious in chronic dysentery as catechu, but is preferred internally in menorrhagia, and as a topical application in leu- corrhea, relaxed sore-throat and aphtha of the mouth or fauces. An infusion thrown into the nostril has suppressed hemorrhage from the Schneiderian membrane : and the powder on lint has suppressed a hemorrhage from a wound in the palate, which had resisted various means. Dose of the powder, from ten to thirty grains; of the tincture, from half a fluidrachm to two fluidrachms. Off. Prep.—Pilula Camphora Composita; Tinctura Kino. KRAMERIA TRIANDRIA. Rhatany. Nat. Ord.—Polygalaceaa, Decandolle ; Krameriaceaa, Lindley. Sex. Syst.— Tetrandria Monogynia. THE ROOT. Description.—Rhatany is a suffruticose plant, with a horizontal, very long and branched root, with a thick bark, reddish-brown externally, and red internally. The stem is round, procumbent, much branched, 584 Materia Medica. taper ; the branches are two or three feet long, white and silky when young, but black and naked when old. The leaves are alternate, sessile, oblong-ovate, pointed, entire, and covered on both surfaces with silky hairs. The flowers are lake-colored, solitary, axillary, and on short peduncles. The calyx consists of four red sepals, the inferior largest, hairy externally, but smooth and shining on the inner surface. The corolla is formed of four petals, the two upper separate, spathulate, the two lateral, roundish and concave. Stamens three, hypogynous, with small, urceolate anthers, having two openings at their apex. The ovary is ovate, supporting a small red style, crowned with a simple stigma. The fruit is a dry, globose berry or drupe, about the size of a pea, covered with stiff reddish-brown hairs, and furnished with one or two seeds. History.—This species of Krameria is a native of Peru, usually grow- ing in dry argillaceous and sandy places, on the sides of mountains, flowering throughout the year, but most freely in October and Novem- ber. It was long known to the natives as a powerful astringent, pre- vious to its discovery in 1780 by Ruiz. The root is the officinal part; it is dug up after the rains in large quantities, and after being well dried are exported, principally to Portugal, where they are employed to adul- terate red wines. Sometimes an extract is prepared from them, which is exported and used in a similar manner. As imported, it consists of a short root-stock from half to two inches in diameter; and several roots proper, which are simple or branched, one or two feet long, and between the thickness of a goosequill and that of a man's thumb. Its bark is dark brownish-red, wrinkled, and warty on the root-stock, brittle, inodo- rous, and of a strongly astringent and slightly bitterish taste. The woody interior is yellowish-red, dense, tough, and of the same taste, but much weaker. Cold water, rectified, or proof spirit, readily extracts its active constituents. In powder it is of a reddish color. The bark contains more of the medical virtues than the ligneous or woody part. By maceration, boiling water takes up the virtues of the root, forming a turbid solution on cooling, in consequence of the deposition of apo- theme taken up by the water when heated. If boiled, a still greater quantity of apotheme is dissolved, and a large amount of tannin becomes insoluble in cold water, and without medicinal virtue, in consequence of its combination with the dissolved starch, or by the action of the at- mosphere converting it into apotheme. Hence, the decoction, and the extract formed from it, contain much less soluble and active matter, than that from the cold infusion, and are therefore ineligible prepara- tions. By displacement, cold water removes all the astringent virtues of rhatany, forming a clear deep-red infusion, from which an active and almost perfectly soluble extract may be obtained by careful evapora- tion. Alcohol takes up but little more of its astringent principle than cold water, with much inert matter. Rhatany root consists of tannin in Lactuca Sativa—Lactuca Virosa. 585 a state of purity, in a state of apotheme, deprived of its astringency, and insoluble from the action of the air, and in a state of extractive or a combination of tannin and apotheme, also lignin, an acid termed Krameric acid, and small proportions of gum, starch, saccharine matter, etc. Its preparations are incompatible with the mineral acids, and most of the metallic salts. Properties and Uses.—Rhatany is a powerful astringent, with some slight tonic virtues. It may be employed internally with advantage, in menorrhagia, hematemesis, passive hemorrhages, chronic diarrhea, leucorrhea, chronic mucous discharges, colliquative perspiration, and incontinence of urine. Also as an energetic styptic in epistaxis, hemor- rhage from the cavity of an extracted tooth, or the surface of a wound, and as a local application to prolapsus ani, fissure of the anus and leu- corrhea. As an application to spongy and bleeding gums, to redden and consolidate them, as well as to preserve the teeth, the following paste will be found unsurpassed: Take of prepared chalk, and powdered cinchona, of each, equal parts; combine them with a sufficient quantity of equal parts of the tinctures of rhatany and myrrh, to form a paste. Use daily with a brush. Dose of the powder from ten grains to thirty; of the tincture from one to four fluidrachms; of the infusion from one to four fluidounces; of the extract from ten to twenty grains. Off.

Compositaa Cichoraceaa, De Candolle. Sex. Syst.—Syngenesia iEqualis. THE HERB, AND INSPISSATED JUICE--LACTUCARIUM. Description.—Lactuca Sativa has an annual, tap-shaped root, with an erect, round stem, simple below, branching above, and about two feet in hight. The lower leaves are obovate, rounded at the end, and undulating; the upper are smaller, sessile, cordate, and toothed; both are shining, and of a yellowish-green color. The flowers are pale-yellow, small, and disposed in an irregular terminal corymb. Before the flower-stem begins to shoot, the plant contains a bland, pellucid juice, has little taste or smell, and is much used as a salad for the table; but during the period of inflorescence it abounds in a peculiar milky juice, which readily escapes from incisions in the stem, and has been found to pos- sess decided medicinal properties. 586 Materia Medica. Lactuca Virosa has a tap-shaped root, with a solitary stem, two or three feet high, erect, round, smooth, sparingly leafy, scarcely branched; panicled at the top; a little prickly below. The leaves are horizontal, nearly smooth, finely toothed; radical ones numerous, obovate, undi- vided, depressed; those of the stem smaller, often lobed; arrow-shaped and clasping at their base ; the midrib of all more or less beset under- neath with prominent prickles; such as often occur-on the margin also. Flower-heads numerous, panicled, with abundance of small, heart-shaped, pointed bracteas. Involucral scales downy at the tip, destitute of any keels or ribs. Corolla small, light-yellow. Pappus rough. There are many varieties of lettuce which differ much from each other; as an application to all of them, it may be said, that they have large, milky, frequently wrinkled leaves, usually of a pale-green, but varying to a light-red. The radical leaves are roundish and toothed at the margin; those of the stem obovate or cordate. The stem is round, leafy, corym- biform at top, with numerous bright-yellow flowers. History.—The native country of this plant is unknown ; but it is cultivated in all parts of the civilized world. The Lactuca Elongala of our country, was presumed for a time to possess narcotic principles similar with the others, but on investigation it has been ascertained to be nearly if not entirely inert. Lactucarium or lettuce-opium is obtained from these plants, by cutting across their stems, at the time of inflo- rescence, Avhen a milky fluid exudes from the surface of the cut; this is absorbed by cotton or a piece of sponge, and is pressed out into a small vessel, when, by exposure to the air, it concretes. By making another cut at a short interval below the first, and so proceeding six or seven times daily, or even oftener, the whole juice of the plant may be obtained. There are several other modes recommended for procuring the lactucarium, but no one of them obtains an article equal to that collected by the above plan. After the middle period of inflorescence, the juice becomes thicker but deteriorated in its medicinal principles. A single plant of L. Sativa is said to yield seventeen grains of lactuca- rium, while a plant of L. Virosa gives fifty-six grains. As found in the shops, lactucarium is in roundish, compact, rather hard masses, weighing several ounces, of a reddish-brown color externally, of a bitter, nar- cotic and somewhat acid taste, and an odor approximating that of opium. It is asserted that two other varieties, the L. Scariola, and L. Allissima, furnish a superior article of lettuce-opium. Lactucarium does not attract moisture from the atmosphere ; is soft- ened by heat, and at a high temperature burns with a large white flame. Cold water takes up about a sixth of it, forming a deep-brown infusion; boiling water a third, and proof spirit, alcohol and ether a much larger proportion. The addition of acetic acid to water or alcohol improves their solvent powers upon this article. It contains neither morphia nor narcotine, but is found to consist of lactucin, volatile oil, a yellowish-red Lactuca Sativa — Lactuca Virosa. 587 tasteless resin, a greenish-yellow acrid resin, crystallizable and uncrys- tallizable sugar, gum, pectic acid, albumen, a brown basic substance, a principle like humus-extractive, a concrete oil or wax, one part of which is soluble in ether, and fusible only at 212°, and the other insoluble in ether and fusible at 167°, and numerous salts, particularly oxalates. Lactucin is obtained by treating finely-powdered lactucarium with alcohol acidulated with one fifteenth of acetic acid, adding an equal volume of water, and precipitating the mixture with a slight excess of subacetate of lead; filter the solution and free it from the lead by sul- phureted-hydrogen gas, filter, evaporate by a gentle heat not exceeding 144°—treat the extract with absolute alcohol, then distil it off, and again exhaust with ether, which by distillation or spontaneous evapora- tion, forms crystals of an obscure acicular character. When pure they are colorless, inodorous, intensely bitter, easily fusible, soluble in sixty or eighty parts of cold water, more soluble in ether, still more so in alcohol, and easily soluble in acids, especially acetic acid, but without neutralizing them. In regard to this being the active principle of lac- tucarium, there is yet much dispute; several analysts have differed in their results and conclusions. The most recent analysis is by Ludwig, who in connection with several other principles, obtained lactucic acid and lactucin. " To obtain these principles, eighty parts of lactucarium in fine powder, were triturated with eighty of pure cold diluted sulphuric acid, and then mixed with four hundred parts of alcohol of 0.851; the liquor was filtered, shaken with hydrate of lime till it yielded no precipi- tate with baryta-water or oxalate of potassa, then decolorized with pure animal charcoal, and evaporated; the brown tenacious mass, thus obtained, (alcoholic extract) was treated with boiling water, which left behind a viscid substance ; the aqueous solution was treated with animal charcoal, and on being evaporated yielded a mixture of lactucic acid and lactucin ; these were separated by dissolving the mixture in boiling water, which on cooling deposited the latter in white crystalline scales, and gave up the former upon subsequent evaporation. Lactucic acid is of difficult crystallization, light-yellow, strongly bitter, Avithout sour taste, of an acid reaction, and readily soluble in alcohol and water. It has as much claims as any other discovered substance to be considered the active principle of lactucarium. Lactucin, purified by animal char- coal, is in white pearly scales, the solution of which exhibits no reaction with subacetate or acetate of lead, or solution of iodine. It is dissolved without change of color by concentrated sulphuric acid." Thridace, is the inspissated expressed juice obtained by collecting the stalks near the flowering period, depriving them of their leaves, and then subjecting them to pressure. Properties and Uses.—Lactucarium has never been thoroughly and satisfactorily investigated in relation to its therapeutical influences; indeed, various experimenters differ in their views on this point, some 588 Materia Medica. asserting it to be a stimulant and others a sedative. It is, when employed at all, usually given as a calmative and hypnotic, and as a substitute for opium, to which it is to be preferred in many instances, on account of its freedom from unpleasant after-effects, as constipation, excitement of the brain, etc. However, it is not considered equal in power to opium. The most energetic lactucarium is said to be obtained from L. Virosa, and L. Altissima. Moderate doses of it act as a nar- cotic poison on the lower animals, and ten or twenty grains'swallowed by a dog will cause sleep, or the watery solution injected into a vein occasions sleep, coma, and death. Dose of lactucarium in pill or pow- der, which is the most efficient mode of administration, from five to twenty grains; of the tincture, thirty to sixty drops; of the alcoholic extract, one to five grains. The article is seldom used in medical prac- tice on account of its high price, its uncertain power, and its liability to adulteration. LARIX AMERICANA. American Larch. Nat. Ord.—Pinaceaa or Coniferaa. Sex. Syst.—Moncecia Monadelphia. THE BARK. Description.—This is the Pinus Pendula, Pinus Microcarpa, and Abies Americana of various botanists, and is known by the several names of Black Larch, Tamarac, Hackmetack, etc. The tree has a straight and slender trunk, with slender horizontal branches and attains the hight of eighty or a hundred feet. The leaves are short, one or two inches long, very slender, almost thread-form, soft, deciduous, without sheaths and in fascicles of from twenty to forty, being developed early in the spring from lateral scaly and globular buds, which produce (the same or the second year) growing shoots on which the leaves are scattered. The cones are oblong, of few rounded scales, inclining upward, from half an inch to an inch in length, and of a deep purple-color. Scales thin and inflexed on the margin. Bracts elliptical, often hollowed at the sides, abruptly acuminate with a slender point, and together with the scales, persistent. History. — This is a beautiful tree, more common throughout New England; it is found in swamps and moist places, and flowers in April and May. It may be distinguished from the pines, by the branches being without leaves for nearly half the year. Its wood is very heavy, strong and durable, and is the most valuable of all the pines or spruces. The bark is the part used as medicine. Properties and Uses.—A decoction of the bark of this tree is said to be laxative, tonic, diuretic, and alterative, and is recommended in obstructions of the liver, rheumatism, jaundice, and some cutaneous dis- eases ; a decoction of the leaves has been employed, in piles, hemopty- Laurus Sassafras. 589 sis, menorrhagia, diarrhea and dysentery, and externally in cutaneous diseases, ulcers, burns, etc. In dropsy, combined with spearmint, juni- per berries and horseradish, it has proved valuable.

Syst.—Enneandria Monogynia. THE BARK OF THE ROOT. Description.—This is a small indigenous tree, varying in hight from ten to forty feet, and having a trunk about a foot in diameter, covered with a rough, deeply-furrowed and grayish bark — that on the twigs, however, being smooth and beautifully green. The leaves are alternate, petiolate, membranous, bright-green, smooth above, finely downy beneath, especially when young, very variable in form, from ovate and entire to three-lobed, or lobed only on one side, all, however, tapering to the base. The greater number are three-lobed, and their mean length is four or five inches. The flowers appear before the leaves, are fre- quently dioecious, small, of a pale greenish-yellow color, and are arranged in naked, downy corymbose racemes which are terminal and axillary, and have subulate, deciduous bracts at their base. The calyx is six-parted, permanent at base. The sterile flowers have nine stamens, the fertile only six with a simple style. The fruit is an oval drupe of a deep-blue color when ripe, about as large as a pea, and supported in the permanent base of the calyx on the thick, red, clavate peduncle. History. — Sassafras is a well-known tree growing throughout the United States, and extending into Mexico, and flowering in the latter part of April or early in May. Its flowers have a weak, agreeable odor, and are, as well as the twigs, much used in domestic practice, in decoc- tion, as a purifier of the blood in spring. The officinal parts are the bark and the pith. The root is largely exported, it consists of a brown- ish-Avhite Avood, and an external spongy bark, both of which are recog- nized as officinal by the foreign authorities. The bark of the root, is the part generally employed in this country, it is by far the most active part of the whole tree. It is found in the shops, in small irregular pieces, of a grayish-brown' color on the surface, rusty-brown within, very brittle, of an agreeable odor, and a powerful, peculiar, warm, aro- matic, sweetish taste. It owes its properties to a volatile oil, which may be separated by distillation with water. Hot water, in infusion, or alcohol takes up its active properties, but boiling dissipates them. The bark contains a heavy and light volatile oil, camphorous matter, fatty matter, resin, wax, a principle resembling tannic acid, called Sassafrid, 590 Materia Medica. tannic acid, gum, albumen, starch, red coloring-matter, lignin, and salts. The pith of the extremities of the branches is in light, spongy, slender, and cylindrical pieces, with a mucilaginous, slightly7 sassafras-flavored taste. It is full of gummy substance, affords a clear but viscid muci- lage in water, much less tenacious than that of gum arabic, and which is not affected by alcohol. Properties and Uses.—Sassafras is a warm aromatic stimulant, altera- tive, diaphoretic, and diuretic. It is generally used in combination with other alteratives whose flavor it improves, in syphilitic affections, chronic rheumatism, scrofula, and many cutaneous eruptions. The mucilage of the pith is used as a local application in acute ophthalmia, and as a demulcent drink in disorders of the chest, bowels, kidneys, and bladder. The oil is used to afford relief in the distressing pain attending men- strual obstructions, and that following parturition, in doses of from five to ten drops, on sugar; also used in diseases of the kidneys and bladder. Externally, as a rubefacient, in painful swellings, sprains, bruises, rheu- matism, etc., and is said to check the progress of gangrene. Off.

Syst.—Didynamia Gymnospermia. THE FLOWERS.^ Description.—Lavandula Vera, of De Candolle, is a small shrub gene- rally one or two feet high, but sometimes growing to even six feet. The leaves are oblong-linear, or lanceolate, entire, opposite, sessile, tapering to the base, Avhen young hoary and revolute at the edges; upper ones linear-lanceolate, the highest shorter than the calyx and the lower petio- lated. The flowers are of a lilac color, small, in terminal, cylindrical spikes consisting of interrupted whorls, in which the florets are from six to ten, each whorl being furnished with two small, ovate bracts. The corolla is tubular, and divided into two lips, the uppermost of which is larger and bifid, the loAver declining, and of three segments. The sta- mens are four, with small, simple anthers. The style is slender, and covered by a bilobate stigma. Lavandula Spica of De Candolle is more dwarfish and more hoary than the last. The leaves are oblong-lanceolate, somewhat spathulate, entire, much narrowed at the base, hoary on both sides. Spikes some- what interrupted. Bracts linear-subulate, shorter than the calyx. This plant is not used in medicine, but yields what is called Oil of Spike, much used in the preparation of artistical varnishes and by porcelain painters. Ledum Latifolium. 591 History.—Lavandula Vera is a native of the south of Europe, growing in dry, barren lands. It is extensively cultivated in this country, and flowers in July and August. When too thickly planted, the plant suffers from a disease which is removed by thinning them. All parts of the plant are aromatic, but the flowers only are officinal; they are cut when they begin to bloom, and dried in the shade. They have a rich, pecu- liar fragrance, which is retained long after drying, and a strong, bitter, aromatic, somewhat camphoraceous taste. Alcohol extracts their virtues, which probably depend upon their volatile oil, from half a drachm to two drachms of which may be obtained from a pound of the fresh flowers.

Capsule ovate-oblong', subpubescent, fiAre-celled, five-valved; valves splitting from the base upward, with the margins inflexed and connivent; receptacles linear, extending into the cells of the capsule. Seeds minute, terminating in a membrane at each extremity. History.—This plant is a native of North America, and is found in the northern parts of the United States and in Canada, growing in cold bogs, and damp mountain woods, flowering in June and July. It is also found in the mountainous regions of more southern latitudes. The leaves have a pleasant odor and taste, and were substituted for tea- leaves during the revolutionary Avar. Its virtues are extracted by water in infusion, and alcohol. Ledum Palustre or Marsh Tea, inhabiting swamps and wet places in the northern parts of Europe, Asia, and North America, may be known 592 Materia Medica. by its linear leaves, having uniformly ten stamens, and especially by its oval pods. The leaves have a balsamic odor, and an aromatic, camphor- ous, bitter taste, and contain among other ingredients, volatile oil and tannin. Water by infusion, or alcohol extracts its properties. Properties and Uses. — Ledum Latifolium is pectoral and tonic ; and is useful in coughs, irritations of the pulmonary membranes, and in dyspepsia. Reputed also to possess similar but less energetic properties than the Ledum Palustre, which is supposed to possess narcotic powers. An infusion of the leaves has been successfully employed in decoction in pertussis, dysentery, and to allay irritation in exanthematous diseases. In leprosy, scabies, and various cutaneous affections, the decoction inter- nally and externally has been beneficially used. When placed among clothes, they are said to prevent the attacks of moths. A strong decoction, used externally, Avill kill lice and other insects. Dose of the infusion of either of the above plants, from 2 to 4 fluidounces, 3 or 4 times a day. Off. Prep.—Infusum Ledi. LEONURUS CARDIACA. Motherwort. Nat. Ord.—Lamiaceaa. Sex. Syst.—Didynamia Gymnospermia. THE TOPS AND LEAVES. Description.—Leonurus Cardiaca is a perennial plant, with stems from two to five feet in hight, wand-like, minutely downy, acutely quadran- gular, with intermediate channels, purplish, and beset with numerous pairs of opposite, long-stalked, rough, dark-green, somewhat downy leaves, arranged in four vertical rows. The lower stem-leaves are palmate-lobed, and broadest; the upper ones acutely three-lobed ; those about the summit lanceolate and undivided; all of them toothed, cunei- form at base. The fiowers are purplish or whitish-red, and are disposed in numerous, axillary whorls. Calyx rigid and bristly. Corolla purplish, the upper lip clothed Avith dense, white, shaggy, upright hairs; the lower deeply colored, variegated, smooth, in three nearly equal entire lobes; the middle lobe obcordate. Stamens didynamous ; anthers approximated in pairs, with parallel transverse cells and naked valves, and sprinkled with shining dots. Achenia oblong, ribbed, and roughened on the ribs, the apex prolonged into a very slender thread-like beak, bearing the pappus of copious soft and white capillary bristles. History. —Motherwort is an exotic plant, but extensively introduced into this country, growing in fields and pastures, and flowering from May to September. It is supposed to be a native of Tartary, and may probably be indigenous to the northern sections of this country. After blossoming, the inner involucre closes for a time, the slender beak elon- gates and raises up the pappus while the fruit is forming ; the whole involucre is then reflexed, exposing to the wind the naked fruits with Leptandra Virginica. 593 the pappus displayed in an open globular head. The root sends forth a number of small, long fibers of a dark-yellowish color. The whole plant is officinal. It has a peculiar, aromatic, not disagreeable odor, and a slightly aromatic, bitter taste, and yields its properties to water or alcohol. The plant has not been analyzed. Properties and Uses. — Motherwort is emmenagogue, nervine, anti- spasmodic and laxative. It is usually given in warm infusion in amenorrhea from colds ; and in suppressed lochia, we have found it superior to any other remedy7. Likewise useful in hysteria. The ex- tract is recommended in nervous complaints, pains peculiar to females, in irritable habits, delirium tremens, typhoid stages, with morbid nervous excitability, all chronic diseases attended with restlessness, wakefulness, disturbed sleep, spinal irritation, and neuralgic pains in the stomach and head, and in liver affections. Combined with Ictodes and Cimicifugin, it forms a superior antispasmodic, nervine and emmenagogue. Externally, it may be used as a fomentation to the bowels, in suppressed or painful menstruation, etc. Dose of decoction, from two to four fluidounces, every one, two or three hours ; of the extract, from three to six grains, every two or four hours. The root in infusion is diuretic. The seeds haAre been given in half teaspoonful doses in Avater, in bilious colic, and, it is said, will pass through the bowels when quicksilver will not; they must not be pulverized. This, however, requires more satisfactory evidence. Off. Prep. — Decoctum Leonuri; Extractum Leonuri Hydro-alco- holicum ; Pilula Leonuri Composita. LEPTANDRA VIRGINICA. Leptandra. Nat. Ord.—Scrophulariaceaa. Sex. Syst.—Diandria Monogynia. THE ROOT. Description. — This is the Veronica Virginica of Linnaus, and is known also by the names of Culver's Physic, Tall Speedwell, Blackroot, etc. It is an indigenous, perennial plant, with a simple, straight, smooth herbaceous stem, from two to five feet in hight. The leaves are whorled in fours to sevens, short-petioled, lanceolate, acuminate, finely serrate, and glaucous beneath. The fiowers are white, numerous, nearly sessile, and disposed in long, terminal, and verticillate, sub-terminal spikes. Spikes panicled, crowded; bracts very small. Calyx four-parted. Corolla small, nearly white, with a deeply four-cleft, spreading border, the lateral or lower segments narrower than the others, tubular, pubescent inside ; tube of the corolla longer than its limb and much longer than the calyx. Stamens two, very much exserted. Capsule oblong-ovate, not notched, opening by four teeth at the apex, many-seeded. History.—This plant grows throughout the United States, in limestone countries, and in rich moist places, woods, thickets and barrens, and 38 594 Materia Medica. floAvers in July and August. The root is perennial, horizontal, irregular, woody, about as thick as the finger, from six to twelve inches long, blackish externally, brownish internally, with many long slender, dark fibers, issuing horizontally in every direction. It is the officinal part, and should be gathered in the fall of its second year. When fresh it has a faint odor and a bitter, nauseous taste, which is somewhat lessened by drying, and yields its active properties to boiling water, or still better to alcohol. Age impairs its A7irtues. It has not been satisfactorily ana- lyzed, but is said to contain an essential oil, bitter extractive, tannin, gum, resin, and woody fiber. Properties and Uses.—The fresh root is too drastic and uncertain for medicinal use, producing vomiting, bloody stools, dizziness, vertigo, and in pregnant females, abortion, unless used Avith much care. A decoc- tion or extract of the fresh root is highly recommended in intermittent fever; my colleague, Prof. W. Byrd Powell, who has tested it, states that it removes the disease, and leaves the system in a condition to repel a fresh attack or relapse; but it must be used with caution, as it is apt to produce unpleasant symptoms. The dried root is laxative, chola- gogue and tonic ; and is employed with much success in all hepatic affections, as it causes the liver to act with great energy, and without active catharsis. In all febrile diseases it is an excellent laxative, and may be given daily in tablespoonful doses of the infusion, repeated every hour, until one or two moderate evacuations are procured; it is pecu- liarly applicable to bilious and typhoid fevers, causing discharges of a black, tarry and morbid character, without debilitating the tone of the bowels or of the general system. It has been successfully employed in leprosy and cachectic diseases, and its effects in these instances, may, probably, be owing to its influence on the biliary apparatus. As a laxa- tive and tonic in small doses, it is very valuable in dyspepsia, especially when connected with an inactive condition of the liver, and torpid and debilitated bowels, likewise in all functional diseases of the liver, as above remarked. It exerts a powerful influence upon the absorbent system, and in combination with cream of tartar, has been successfully used in obstinate cases of dropsy. In diarrhea and dysentery, it has proved very beneficial as a cathartic, one active dose frequently effecting a cure. By some it is said to possess narcotic properties, and that, during its operation, it will frequently be necessary to rouse the patient lest he fall into a deep sleep. I have neA7er witnessed this effect. Dose of the poAvdered root as a cathartic, from tAventy to sixty grains, which maybe given in sweetened water; of the infusion, in typhoid stages, half a fluidounce every hour, until it operates, and to be repeated daily. Dose of the hydro-alcoholic extract, Avhich is its best form of adminis- tration, from one to five grains in form of pills. Off.

Preparation. — Leptandrin may be prepared as follows: Take of coarsely-powdered Leptandra any quantity, alcohol 90 per cent., a suf- ficient quantity. By percolation, obtain a saturated tincture. Place the tincture in a still, and distil off the alcohol, and while hot add the resi- duum slowly and gradually to cold water, equal to two or three times its volume. Allow this to stand for seven or eight days, when the resinous matter will precipitate to the bottom of the vessel in a semi-liquid mass, while the water will hold in solution most of the extractive and coloring matter. Remove this water, and to the residue add a fresh supply of cold water, subjecting it to another washing. Then carefully remove the water, after having allowed all the resinous matter to precipitate, which last must be dried in shallow tin or porcelain plates by a mode- rately-continued heat, until it becomes perfectly friable on cooling, and which generally requires several days. In the preparation of this arti- cle, high-proof alcohol must be employed, on account of the large amount of extractive matter present, which is soluble in water, and which, according to the proportion of water present in'the tincture, pre- vents the precipitation of the leptandrin. Care must be taken likewise in the application of heat, as too great a heat, say above 175° or 180p will render the precipitate inert, or materially affect its character. The above is the process usually employed in the preparation of leptandrin ; it may be obtained, however, by adding the tincture to four times its weight of water, distilling off the alcohol, and setting aside the residue for several days, until all the leptandrin precipitates. Remove the water, and dry the precipitate as above, having previously washed it in fresh water to remove extractive, etc. Roots of the second year's growth, are said to afford the most leptandrin. History.—Leptandrin, according to its mode of preparation, is a jet- black resinous substance, resembling pure asphaltum, or of a grayish- brown color, with a peculiar, faint cyanic smell and taste, somewhat bitter, but not disagreeable. In its aggregate form, it has a vitreous fracture, is unalterable in a dry atmosphere, and is without acid or alkaline reactions. Its powder has a black, glistening, soot-like appearance, and coalesces in a warm and moist air. When first made it is soluble in alcohol, though as with many other resins upon exposure to atmospheric influence, it becomes imperfectly soluble in alcohol, but perfectly so upon the addition of aqua ammonia. It is insoluble in water, but the addition of liquor potassa or aqua ammonia, renders it completely solu- ble, from which solutions it is precipitated by acids. Ether takes up a portion of it, and aqua ammonia added perfectly dissolves it, leaving 596 Materia Medica. the ether floating above of a light reddish-yellow color. It is lighter than chloroform, and is insoluble in it. Spirits of turpentine takes up a small portion, forming a dirty-white liquid; acetic acid likewise dissolves a small proportion. None of the above agents have been tried with heat. Nitric acid turns leptandrin a brownish-yellow color; muriatic acid, a light yellowish-green ; and sulphuric acid, reddish-brown. Heat semi- liquefies it, and it burns with a bright white flame, giving out a sweet, balsamic, rather agreeable odor, somewhat resembling balm of Gilead buds when burned, or incense. This valuable agent was first prepared and introduced to the profession by W. S. Merrell, of Cincinnati. Properties.—Leptandrin is a powerful cholagogue, with but slight lax- ative influence; except given in very large doses its cathartic powers are but very feeble. It is one of the most efficacious and important agents among those peculiar to Eclectic practice, being the only known medi- cine that efficiently stimulates and corrects the hepatic secretions, and functional derangements of the liver, without debilitating the system by copious alvine evacuations. It may be safely and efficaciously employed in the treatment of diarrhea, cholera-infantum, some forms of dyspepsia, typhoid fever, and all diseases connected with biliary derangements. Combined with podophyllin it is a prompt and effectual remedy in epi- demic dysentery, often effecting a permanent cure in from twelve to eighteen hours; in dysentery with irritable bowels, it may be used alone with advantage, or combined with camphor, as in such cases its union with podophyllin is contra-indicated. In intermittents it renders the action of quinia, when united with it, more certain, and prevents the liability to a return of the disease, at least for the season, and is likewise highly7 beneficial in infantile remittent fever, and in periodic diseases generally, of an obstinate character, in which quinia alone seems to produce but little or no result. It may also be used in many other com- binations with much advantage, as with Hydrastin, or dried beef's gall, in some dyspeptic affections, jaundice, piles, etc., or with Iridin, Bapti- sin, Phytolaccin, Corydallin, Caulophyllin, and other active principles, in various forms of disease. Dose of Leptandrin, from one-half of a grain to five or six grains, every three or four hours, according to the action or effect desired. Some practitioners neglect the use of this agent, because it does not act so powerfully as podophyllin, and hence lose the influence of a very important remedy in functional derangements of the liver, and other organs essential to digestion. In relation to this article, a late Professor in the Eclectic school, observes : "This is not strictly speaking a cathartic. It is aperient, alterative, and tonic. Its effects on the liver are peculiar. In cases of children afflicted with summer complaint, where there is evidently a lack of the proper biliary secretion, but where, owing to the already irritated condi- tion of the bowels, the ordinary medicines for arousing the liver are Leptandrin. 597 inadmissible, this article seems to be the very thing needed. While it acts freely upon the liver, instead of purging it seems only to change the discharges from the light and watery or slimy condition, to a darker and apparently bilious state, rendering them more and more consistent, until they become perfectly natural, without having been arrested entirely, or at any time aggravated. It at the same time seems to act as a tonic, restoring the tone of the stomach and increasing the strength and activity of digestion. It is a most valuable remedy in dyspepsia. " The dose is from one-fourth to one grain every one or two hours in acute cases, and from one to two grains three times a day in chronic cases. It is valuable to combine with Podophyllin as a remedy in dys- pepsia and chronic hepatitis. "In the epidemic dysentery, which has prevailed for the past two sea- sons, in many parts of our country, this article has been of great service. It was usually given with the best success after evacuating the bowels freely, with a combination of Podophyllin and Leptandrin or Rhubarb. For this purpose, give from one-half of a grain to one grain every hour, gradually lengthening the intervals as the discharges become darker. Though it may not be applicable in all cases of dysentery, it is doubtless one of the most useful articles in this dangerous disease." In cholera-infantum, a disease which sometimes sets at defiance all the skill of the physician, I have met with excellent success by the fol- lowing combination : Take of Leptandrin six grains, Quinia three grains, Camphor one grain and a half, Ipecacuanha three-fourths of a grain. Mix and divide into twelve powders, of which one may be given every two or three hours, and its use continued thus for several days. Its action at first is to increase the alvine passages and apparently augment the disease, but in a few days the character of the evacuations change, become more and More normal, as well as more regular in their appear- ance ; after which, one or two powders per day for a week, will render the cure permanent. This powder, in large doses for adults, will be found very efficacious in painful diarrhea and dysentery, as well as in 6evere pains depending upon intestinal irritation. The following has also been of advantage in cholera-infantum : Triturate together, Charcoal one drachm, with Leptandrin three grains, and divide into twelve powders, of which one powder is to be given every two or three hours until the evacuations become more natural, after which, give one or two powders a day for a few days.

Pappus permanent, colored, barbellate, not evidently plumose to the naked eye. Receptacle naked. This plant is found in moist places in the middle and southern states, and is found in abundance in the prairies. Liatris Squarrosa or Blazing Star, has also a perennial tuberous root, with a stem two to three feet high, thickly beset with long-linear, nerved leaves, the lower ones being attenuated at the base. The heads are few, sessile or nearly so, with brilliant purple flowers ; racemes flexuous, leafy, involucre ovate-cylindric ; scales of the involucre large, numerous, squar- rose-spreading, outer ones larger, leafy, inner ones mucronate-acumi- nate, scarcely colored. Pappus plumose. This plant is likewise found in the middle and southern states, growing in dry soil, and is known in the south by the name of Rattlesnake's Master. Liatris Scariosa or Gay-feather, has a perennial, tuberous root, with a stout, scabrous-pubescent stem, from four to five feet in hight, and whitish above. The leaves are numerous, lanceolate, tapering at both ends, glabrous, with rough margins, entire, lower ones on long petioles and from three to nine inches long, upper ones from one to three inches in length, by from one to three lines in width. Heads from five to twenty, an inch in diameter, in a long raceme, with from twenty to forty purple flowers. Involucre globose-hemispherical; scales of the involucre obo- vate or spathulate, very obtuse, with dry and scarious margins, often colored. Pappus scabrous. This plant is found in dry woods and sandy fields from New England to Wisconsin, and extending southward. History.—All the above plants are splendid natives, and flower through August and September. There are several other species of this genus which appear to possess medical properties analogous to each other, and which deserve further investigation, as the L. Odoratissima, L. Cylin- dracea, L. Graminifolia, etc. The roots are the officinal parts ; they are all tuberous, with fibers of an acrid, bitterish, pungent taste, and an aromatic, terebinthinate odor, which properties are owing to the presence Ligustrum Vulgare. 599 of a peculiar balsamic resin ; water partially extracts its virtues, but alcohol, wholly. They have not been analyzed. The resin obtained from them might, probably, prove a valuable agent. Properties and Uses.—These plants are diuretic, with tonic, stimulant, and emmenagogue properties. A decoction of them is very efficacious in gonorrhea, gleet, and nephritic diseases, in doses of from two to four fluidounces, three or four times a day ; it is also reputed beneficial in scrofula, dysmenorrhea, amenorrhea, after-pains, etc. It is likewise of advantage in sore-throat, used as a gargle, and in injection has proved useful in leucorrhea. Said to be beneficial in Bright's disease, in con- nection Avith Lycopus Virginicus and Aletris Farinosa ; equal parts of each in decoction. These plants are celebrated for their alexipharmic powers in bites of venomous snakes; Rush states, that when bitten, the inhabitants of the Southern States bruise the bulbous roots, and apply them to the wound, at the same time drinking freely of a decoction of them in milk. This requires corroboration. Off. Prep.—Decoctum Liatris. LIGUSTRUM VULGARE. Privet. Nat. Ord.—Oleaceaa. Sex. Syst.—Diandria Monogynia. THE LEAVES. Description.—This plant, also called Privy, Prim, etc., is a smooth shrub, growing five or six feet high, with wand-like branches. The leaves are dark-green, one or two inches in length, and about half as wide, oppo- site, entire, smooth, lanceolate and obovate, obtuse or acute, and on short petioles. The fiowers are small, numerous, white, and disposed in tetramerous, thyrsoid, terminal panicles. Calyx minutely four-toothed, deciduous, short-tubular ; corolla funnel-form, tube short, limb with four spreading, ovate, obtuse lobes. Stamens two, on the tube of the corolla; anthers large, exserted. Style very short; stigma two-cleft. Berries spherical, black, in conical bunches, two-celled, and from two to four- seeded ; seeds convex on one side, angular on the other. History.—Privet is found growing wild in woods and thickets, and along the roadsides from New England to Virginia, and West to Mis- souri, flowering in May and June. It is used in England for hedges, from which place it is supposed to be introduced ; but it is indigenous in Missouri. It is often cultivated in gardens. The leaves are the officinal parts ; they have but little odor, but an astringent, bitter taste. Water or alcohol extracts their virtues. They7 have not been analyzed. Properties and Uses.—Privet leaves are astringent; a decoction of them is very valuable in chronic bowel complaints, ulceration of stomach 600 Materia Medica. and bowels, as a gargle for ulcers of mouth and throat, and as an in- jection for ulcerated ears with offensive discharges, leucorrhea, gleet, and ulceration of the bladder, likewise in diabetes. They may be em- ployed either in decoction or powder. Dose of the powdered leaves, from thirty to sixty grains, three times a day; of the decoction, from two to four fluidounces. The flowers have been employed for similar purposes with the leaves. The berries have a sweetish bitter taste, are reputed cathartic, and to color the urine brown; they have been used for dyeing. Probably the bark will be found equal, if not superior in efficacy, to the leaves. On analysis it was found to contain a peculiar substance called ligustrin, also sugar, mannite, muco-saccharine matter, starch, chlorophylle, bitter extractive, bitter resin, tannin, albumen and salts. It is deserving further attention. Off. Prep.—Decoctum Ligustri. LILIUM CANDIDUM. Meadow Lily. Nat. Ord.—Liliaceaa. Sex. Syst.—Hexandria Monogynia. THE root. Description. — This plant has a perennial root or bulb, consisting of imbricated fleshy scales, from which arises a thick stem from three to four feet in hight. The leaves are scattered lanceolate, and narrowed at the base. The fiowers are large, snow-white, campanulate, smooth inside, and disposed in a terminal raceme. History.—This is an exotic, a native of Syria and Asia Minor, and is much cultivated in this country on account of its beautiful white flowers, which have long been regarded as the emblems of purity, and which appear in June and July. The bulb is the part used, it is inodorous, but has a peculiar, disagreeable, somewhat bitter and mucilaginous taste. It contains a large proportion of mucilage, and a small quantity of an acrid principle which is dissipated by heat. Water extracts its virtues. Properties and Uses.—Meadow Lily, or White Lily as it is sometimes called, is mucilaginous, demulcent, tonic, and astringent. Useful in leucorrhea and prolapsus uteri, the decoction taken internally, and em- ployed in injection ; it is more decided in its effects, when combined with life-root (Senecio Gracilis). Boiled in milk, it forms an excellent poultice for ulcers, external inflammations, tumors, etc. The recent root is stated to have been useful in dropsy. The flowers have an agreeable odor, which is imparted to oil or lard ; and a liniment or ointment is sometimes prepared from them, and used as a soothing ap- plication in external inflammations. The petals contain -a fragrant oil, which has been thought beneficial in earache, and uterine pains. LlNUM UsiTATIbSIMUM. 601 LINUM USITATISSIMUM. Flaxseed. Nat. Ord.—Linaceaa. Sex. Syst.—Pentandria Pentagynia. THE SEEDS. Description.—Flax is an annual plant, very smooth, with a slender fibrous root, and one or more erect, slender, delicate, and round stems, one or two feet high, and branching at the top. The leaves are small, alternate, sessile, lanceolate, acute, entire, three-veined, and of a pale- green color ; the lowermost short and blunt. The fiowers are several, large, of a delicate-blue color, erect, and disposed in a terminal corym- bose panicle, and are supported on long peduncles. The calyx is per- sistent, and has five lanceolate, erect sepals, which are three-nerved at base, and imbricated in astivation. The corolla consists of five thin, delicate, crenate, oblong or obovate, striated petals, readily dropping off, glossy, broad above, narrow below, and contorted in astivation. The stamens are five, subulate, erect, as long as the calyx, united at base, and supporting two-celled sagittate anthers. The ovary is superior, ovate, and surmounted by five blue, slender styles. The fruit is a globular capsule, about the size of a small pea, having the persistent calyx at the base, crowned with a sharp spine, having five cells contain- ing two seeds each, divided from each other by a false dissepiment. Seeds elliptical, smooth, brown, and shining. History.—The native country of Flax is unknown, though supposed to be derived from Egypt, or from Central Asia. It was known at a very early period, as it is mentioned in the ninth chapter, thirty-first verse, of Exodus, as growing in Egypt. At present it is naturalized in nearly all civilized countries. It flowers in June and July, and ripens its seeds in August. The seeds, as well as the oil they yield by expression are officinal. The seeds are small, oval, oblong, flattened on the sides Avith acute edges, somewhat pointed at one end, about a line in length, smooth, shining, of a brown color externally, and yellowish-white within. They are devoid of smell, and have an oily mucilaginous taste, and consist of a mucilaginous tegument and oleaginous cotyledons, When the teguments or husks are steeped in hot water, a peculiar gummy or mucilaginous matter is obtained, viscid, inodorous, and almost tasteless ; alcohol added to this infusion forms a white flaky precipitate, and subacetate of lead affords a copious dense precipitate. In prepar- ing the infusion the seeds should not be bruised as the mucilage resides only in their external coat. When flaxseed mucilage is dried it forms a brown gummy mass, containing in 100 parts, 52.70 of arabin or soluble gum, 29.89 of an insoluble azotiferous gummy principle, and 10.30 of moisture, and yields 7.11 per cent, of ashes. Vauquelin found in it free acetic acid, silica, and various salts of potassa and lime. 602 Materia Medica. The internal portion of the seed, or nucleus, contains a peculiar oil, called Linseed Oil, and which is obtained from the seeds by expression without the aid of heat. It is rather thick, of a pale amber color, inclin- ing to green, of a feeble, peculiar, disagreeable odor, and a nauseous taste. Its density varies from 0.927 to 0.934. It resists a cold of 4° F., without concreting; on exposure to the action of the air, it slowly becomes thicker, and gradually hardens into a firm elastic varnish—on which account it is highly useful in painting, in the formation of printers' ink, and other important applications. It boils at 600° F., is soluble in forty parts of cold alcohol, five of boiling, and in one part and a half of ether ; becomes rancid with facility; and is saponified by the alkalies. When prepared on the large scale, the seeds are roasted before expres- sion, in order to destroy the gummy matter contained in their tegument. Oil Cake, is the cake or refuse which remains after the expression of the oil, as it retains the mucilaginous matter of the husk, it is much used for fattening cattle. Flaxseed Meal is the seeds finely ground; it is of a dark-gray color, highly oleaginous, and when mixed with hot water forms a soft adhesive mass, much used by practical chemists for luting. Flaxseed, according to Meyer, contains fixed oil, wax, resin, extractive, gum, tannin, azotized mucilage, starch, albumen, gluten, and various salts. Properties and Uses.—Flaxseed is used as a demulcent and emollient. Half an ounce of the seeds not bruised, infused in half a pint of boiling water, forms a mucilage which is very useful in urinary diseases, cough, catarrh, dysentery, and inflammatory affections of the lungs, intestines, and urinary passages. When not contra-indicated, the addition of lemon juice improves the flavor; it may be sweetened with loaf-sugar or honey. A decoction of flaxseed, or of flaxseed meal forms an excellent laxative enema; and the meal mixed with hot water forms an excellent emollient poultice. Dose of the infusion, one or two pints daily. Lin- seed oil in doses of two fluidounces twice a day7, is said to have cured severe cases of piles within two or three weeks; while using it, liquors and stimulating diet are to be avoided. It is likewise reputed beneficial when internally administered in dysentery, colic, and lumbricus. Used as an enema it is advantageous in dysentery, hemorrhoids and ascarides; and combined with lime-water, it forms the Carron Oil, an excellent application to burns. One pint of linseed oil, combined with half an ounce each of oils of origanum and wintergreen, forms a pleasant ca- thartic ; to be given in the same doses as castor oil. The oil is consti- tuted of a large proportion of oleic acid, together with margaric acid and Glycerine. Off. Prep.—Cataplasma Lini; Linimentum Calcis.

The leaves are palmate, deeply five to seven-lobed, rounded, smooth and shining, of a rich green color; the lobes finely glandular, serrate and acuminate; the veins villous at their bases. When bruised the leaves are fragrant, and turn crimson or deep-red in autumn. Sterile fiowers in several globular heads arranged in a conical cluster, naked or achla- mydeous; aments monoecious, roundish, surrounded with a four-leaved involucre; stamens numerous, intermixed with minute scales; filaments short; anthers numerous, oblong, subsessile. Fertile flowers consist of two-celled ovaries, subtended by minute scales, all more or less cohering and hardening in fruit, forming a spherical catkin or head; catkins racemed, nodding, inclosed in the bud by a four-leaved deciduous in- volucre. Styles tAvo, long. Fruit a kind of strobile, composed of the indurated scales and capsules. Capsules or pods two-beaked, two-celled, opening between the two awl-shaped or prickly diverging styles. Seeds small, several, amphitropous, with sparing albumen and a straight em- bryo ; cotyledons foliaceous. History.—This is a large and beautiful tree, with fine-grained wood, growing throughout the United States in moist woods from Connecticut and New Jersey, southward; but found in greater abundance in the Southern and Middle States. In warm latitudes, when wounded in the summer, a balsamic juice flows from its trunk; it is of the consistence of thin honey, more or less transparent, of a yellowish-white color, of a peculiar, agreeable, balsamic odor, and a bitter, warm, and acrid taste. It concretes into a soft resinous mass, assuming a darker color, and is known as Sweet Gum, or Liquidamber (Liquidum Liquidambar Styraci- flua). It is soluble in alcohol, oils, lard or fats. According to M. Bonastre, it contains a colorless volatile oil, a semi-concrete substance which rises in distillation and is separated from the water by ether, a minute proportion of benzoic acid, a yellow coloring substance, an oleo- resin, and a peculiar principle, insoluble in water and cold alcohol, for which he proposes the name of styracine. The proportion of benzoic acid is greatly increased by time. Properties and Uses.—It probably possesses virtues similar to the con- crete juice of Styrax officinale, which see. It makes an elegant and agreeable ointment when melted with equal parts of lard or tallow, 604 Materia Medica. which I have found decidedly useful in hemorrhoids, psora, ringworm of the scalp, porrigo scutulata, and many other cutaneous affections; also in that indolent species of ulcer, known as " fever sores on the legs." In anal fistula, it maintains an increased discharge, softens the callosity of the walls of the sinus, and produces a normal result, and effects this without pain to the patient. If necessary, in fistula, a little creosote, or other stimulant may be added to it. This employment of sweet gum is not generally known, and Eclectics would do well to avail themselves of its use in the above diseases. It is also used in chronic catarrh, coughs, and pulmonary affections. LIRIODENDRON TULIPIFERA. Tulip Tree. Nat. Ord.—Magnoliaceaa. Sex. Syst.—Polyandria Polygynia. THE BARK. Description.—This tree is also known by the names of Poplar, White Poplar, Yellow Poplar, and White-wood. It is ordinarilv about eighty feet high, with a diameter of two or three feet, but in favorable situa- tions it frequently attains a hight of one hundred and forty feet, with a diameter of eight or nine feet. The trunk is perfectly straight and cylin- dric, and is covered with a bark of a brown or grayish-brown color, smooth when young, but rugged and furrowed when old. At the top it divides rather abruptly into coarse, crooked branches, in somewhat regular order, giving a symmetrical aspect to the tree ; the bark of the young branches is bluish or of a reddish tinge. The leaves are large, bright green, alternate, on long petioles, smooth, shining, three lobed, the lateral lobes ovate, the middle one truncated and horizontally notched at its summit. In the larger leaves, the lateral lobes are furnished with a tooth-like projection, or additional lobe at some distance below their apex. There is a variety with the lobes of its leaves not pointed, but very obtuse. The flowers are large, solitary, terminal, tulip-shaped, variegated with different colors, greenish-yellow externally, orange within, and from four to six inches in diameter. Bracts two, triangular, falling off as the floAv^r expands. The calyx is double, the inner and proper sepals being three, large, oval, concave, veined, of a pale-green color, spreading at first, but afterward reflexed. The corolla consists of six, seven, or more petals, which are obtuse, concave, veined, of a pale yellowish-green color, and marked with an irregular indented crescent of a bright orange on both sides toward the base. Stamens numerous, with short filaments, and long, linear, adnate anthers. The pistil is a large, conical, acute body, its upper half covered with minute, blackish, recurved stigmas ; its lower furrowed, being a mass of coalescing styles and ovaries. The fruit consists of numerous, long, narrow scales, LlRIODENDRON TuLIPIFERA. 605 attached to a common axis, imbricated in a conical form, attached at the base to a common receptacle, and containing each two seeds; the upper portion of each scale is winged. The seeds are ovate, blackish, one or both often abortive. History.—This is one of the most magnificent and remarkable trees of the American forests, on account of its size, its striking foliage, its beautiful flowers, its useful wood, and its medicinal properties. It is found in rich soils from New England to Florida, attaining its greatest size in the Middle and South-western States, and its flowers appear in the latter part of May, or early in June. The wood is compact, of fine grain, light, and easily worked, and is much used for a variety of purposes ; it has the property of resisting moist atmospheric influences, as well as the attacks of worms. The bark of the root or trunk is the officinal part. It is of a yellowish-white color when its epidermis is removed, the root-bark being the darkest. It is very light and brittle, of a peculiar rather disagreeable odor, and a bitter, pungent, aromatic taste. Age impairs its properties. Water or alcohol takes up its active properties, which are dissipated by long boiling. The bark should be collected during the winter. The virtues of the bark appear to reside in a volatile principle, which escapes during boiling, and to which the name of liriodendrin was given by its discoverer, the late Professor J. P. Emmet. It may be obtained by macerating the powdered bark in alcohol, boiling the tincture with magnesia till it assumes an olive-green color, then filtering, concentrating by distillation till the liquid becomes turbid, and finally precipitating the liriodendrin by the addition of cold water. In the pure state it is white, solid, crystallizable, brittle, insolu- ble in water, soluble in alcohol or ether, fusible at 180°, volatilizable and partly decomposed at 270°, slightly aromatic, with a warm, bitter, pungent taste. It is precipitated from infusion or decoction hj alkalies, and from its alcoholic solution by water; and does not unite with acids nor alkalies. Properties and Uses.—Tulip tree bark is an aromatic, stimulant tonic, and has proved beneficial in intermittents, chronic rheumatism, chronic diseases of the stomach and bowels, worms, and hysteria. In hysteria, combined with a small quantity of Laudanum, it is said to be certain, speedy, and effectual, and also to abate the hectic fever, night-sweats, and colliquative diarrhea of phthisis. The warm infusion is diaphoretic, and under certain states of the system has proved diuretic. Dose of the powdered bark, from a scruple to two drachms; of the saturated tincture, which is the best form of administration, one fluidrachm; of the infusion, from one to two fluidounces; of liriodendrin, from five to ten grains.

Description.—This plant, generally known as Wild or Indian Tobacco, is an annual or biennial indigenous plant, more commonly the latter, with a fibrous, yelloAvish-white root, and an erect, angular, very pubescent or hairy stem, from six inches to two feet in hight, and much branched toward the top. The leaves are scattered, alternate, sessile, ovate or oblong, unequally serrate, and hairy. The flowers are numerous, small, in leafy terminal racemes, and supported on short peduncles, each arising from the axil of a small bract. The calyx is five-toothed, the segments being linear, pointed, and as long as the corolla. The corolla is of a pale-blue color, monopetalous, but cleft on its upper side nearly to its base, bilabiate, with the upper lip divided into two lanceolate seg- ments, and the lower into three oval ones. Anthers united into an oblong, curved body, purple; filaments white. Style filiform; stigma curved, two-lobed, and inclosed by the anthers. Capsule two-celled, ovoid, inflated, striated, ten-angled, and crowned with the persistent calyx. Seeds numerous, small, oblong, broAvn. History.—This is a very common weed, growing in fields and by the roadsides throughout the United States, and floAvering from July to September, or until the occurrence of frost. The Avhole plant possesses medicinal activity, but the leaves and seeds are more usually employed. The root is said to be the most active part of the plant. The proper time for gathering the plant is in August or September, when the cap- sules are numerous. It should be dried in the shade Avith care, when it may be kept Avhole, or in the state of poAvder. When dried it has a faint, irritating, rather unpleasant odor, and a strong, acrid, nauseous taste, very much resembling tobacco, producing a burning acrid impres- sion upon the tongue and fauces, attended with nausea and a flow of saliva. The powdered leaves are of a greenish color — the seeds in powder, brownish. It yields its properties to water by infusion, alcohol, ether, or vinegar. Heat dissipates its active principles, hence it should never be boiled. It contains an odorous volatile principle, lobelic acid, gum, resin, chlorophylle, fixed oil, lignin, salts of lime and potassa, oxide of iron, and a peculiar alkaline principle, named Lobelina, of Avhich the seeds contain double the amount found in any7 other part of the plant. The fixed oil of lobelia may be obtained by bruising the seed between heated rollers, and pressing while hot in a strong linen cloth, between proper iron plates. Its consistence is nearly like that of linseed oil, and possesses the drying qualities common to the fixed oils. It possesses all the medical properties of the seed. Loeelia Inflata. 607 Lobelina may be obtained by bruising one pound of lobelia seed in a mortar, and then adding eight pints of alcohol, and one pint of acetic acid; digest with the heat of the sun for several days, or until the seeds are deprived of*their acrimony, and strain. Evaporate the tincture to two pints, and filter; then, by means of a water-bath, evaporate to an extract. This extract is then to be triturated with magnesia and water, and after repeated agitation for several hours, is strained through calico, and then filtered. This liquor, which holds the lobelina in solution is then shaken repeatedly with fresh portions of sulphuric ether, until the water settling below is deprived of its acrimony. The ethereal solution must now be drawn off with a syphon, or carefully decanted, and then left to evaporate spontaneously. The residue is impure lobelina, of a reddish-brown color, and a honey-like consistence. To obtain it pure, the residue is treated with water, to which a slight excess of sulphuric acid is added, and then boiled with animal charcoal, saturating with magnesia, filtering, agitating repeatedly with fresh portions of ether, till the aqueous portion is deprived of acrimony, then carefully decanting off the ethereal solution as before, or drawing it off with a syphon, and then evaporated again spontaneously. The lobelina thus obtained is a yellowish liquid, lighter than water, of an odor rather aromatic, and an extremely acrid and permanent taste. It is readily soluble in alcohol or ether, but less so in water. Ether will remove it from its aqueous solu- tion, and upon evaporation the lobelina may be again obtained. Its reaction is decidedly alkaline, and with sulphuric, nitric and muriatic acids, it forms soluble and crystallizable salts, but not crystallizable with acetic, and probably tartaric and citric acids. It is instantly pre- cipitated from its solution by tannic acid, with Avhich it forms an insoluble compound. Unless combined with acids, it is decomposed by boiling. It possesses the active properties of the plant in a concentrated form. As an emetic, three to ten drops, sufficiently diluted with water, will generally operate. With vinegar, or citric acid and honey, it forms an oxymel which is very beneficial in bronchitis and cynanche trachealis. By some it is considered as the narcotic (?) principle of lobelia. Lobelia was known to the Penobscot Indians, and was also extensively used by the people of New England in domestic practice, long before the time of Samuel Thomson, its assumed discoverer. Properties and Uses.—Lobelia is emetic, nauseant, expectorant, relax- ant, sedative, antispasmodic, and secondarily cathartic, diaphoretic, and astringent. There is much discordance of opinion among medical men as regards its narcotic properties, many denying that it holds any such influences whatever. When chewed, lobelia produces a disagreeable sense of burning and distension, which extends into the esophagus, terminating in nausea and vomiting, Avith oppressive prostration, relaxa- tion of the muscular system, and a languid pulse. In doses of ten or twenty grains of the leaves or seeds, it is a prompt and efficient emetic, 608 Materia Medica. and may be given in all cases where emesis is indicated; its action is somewhat modified by a combination with ipecacuanha and other vege- table emetics, and rendered safer and more effectual. In very small doses it excites diaphoresis, increases expectoration, diminishes cough, and counteracts spasmodic action. In all diseases of the respiratory organs, as croup, pneumonia, pertussis, catarrh, asthma, and those fits of dyspnoea resembling asthma, it will be, found useful either as an emetic, or expectorant. As with ipecacuanha so with lobelia, it will be found very useful in all febrile diseases, especially during their earlier stages, as it relaxes the system, modifies arterial excitement, and pro- duces diaphoresis, thus tending to equilibriate the circulation, and assisting the vital powers to eliminate morbid humors. As an expec- torant it may be used in tincture combined with tincture of bloodroot, syrup of senega, oxymel of squill, Avine of ipecacuanha, etc. In all cases where relaxation of the system is desired, either to subdue spasm, or otherwise, lobelia will be found a very valuable article—probably no remedy is more effectual. Spasmodic movement is incompatible with nervous and muscular relaxation, hence we find prompt relief in epi- lepsy, hysteria, cramps, tetanus, chorea, convulsions, etc., by the exhi- bition of lobelia in doses sufficient to excite nausea and relaxation. Rigidity of the os uteri has often been overcome by the employment of this drug internally, or as an enema. In strangulated hernia, and other intestinal obstructions, it has been found an excellent relaxant when used in injection; and on this account it is highly beneficial in fractures, dislocations, and tedious labors. It may be given internally, and applied in fomentation externally; the oil may be used externally likewise for the purpose of causing relaxation. Externally, the infusion has been found useful in ophthalmic affec- tions ; and the tincture is a valuable local application to sprains, bruises, rheumatic pains, erysipelas, and erysipelatous inflammations, tetter, and other forms of cutaneous disease, as well as a remedy for the poison from ivy or dogAvood. A poultice of powdered lobelia and slippery-elm bark, with a weak ley-water will be found valuable in erysipelatous diseases, bites and stings of poisonous insects, spasmodic affections of the limbs, pains, and to produce muscular relaxation. The oil of lobelia, as prepared by W. S. Merrell, is valuable in tetanus and some other extreme cases, as it is easy to introduce enough upon the tongue to relax the whole system immediately. On account of its tendency to produce inflammation of the stomach, it should not be em- ployed alone as a common emetic, but a few drops of it should be tritu- rated with sugar, and diffused in chamomile, boneset, or other emetic infusion. One drop of the oil triturated with one scruple of sugar, and divided into from six to twelve doses, will be found highly useful as an expectorant, nauseant, sedative, and diaphoretic, when given every one or two hours, as may be required. As a local application, much benefit Lycopus Virginicus. 609 may be derived from it, where a particular nerve is to be quieted, or a muscle to be relaxed. An excellent liniment may be made of a mixture of half an ounce each of oils of amber and sassafras, a drachm of oil of lobelia, and half a drachm of ethereal oil of capsicum. To be used in painful neuralgic and rheumatic affections. As an emetic, dose of the powder, from twenty to sixty grains ; of the tincture, from two to four fluidrachms. As a nauseant and expectorant, from five to twenty grains. When lobelia does not act as an emetic, it is very apt to purge. There are two other species of lobelia, the Blue lobelia, Lobelia Syphi- litica, and the Red lobelia, L. Cardinalis. The first is diaphoretic, emetic and cathartic ; also diuretic and antisyphilitic, and a strong infusion of it has cured gonorrhea. It has likewise been used in dropsy, diarrhea, and dysentery. The root is the part used ; dose, from twenty to sixty grains of the powder. The L. Cardinalis is said to be anthelmintic, nervine, and antispasmodic. These two varieties are seldom, if ever, used in medicine. Off.

LYCOPUS VIRGINICUS. Bugleweed. Nat. Ord.—Lamiaceaa. Sex. Syst.—Diandria Monogynia. THE HERB. Description.—This plant, also known as Paul's Betony, and Water Horehound, is indigenous, with a perennial, creeping fibrous root, from which arises an erect, herbaceous, furrowed, somewhat pubescent, obtusely quadrangular stem, nearly simple, and from one to two feet in hight. The leaves are opposite, sessile, broad-lanceolate, attenuated and entire at both extremities, remotely serrate in the middle, somewhat rough, purplish, and beset Avith glandular dots on their under surface. The flowers are minute, sessile, in axillary whorls, with two subulate bracts at the base of each flower. The calyx is tubular, four-cleft, shorter than the seeds, persistent; segments ovate-lanceolate and acute. Corolla white, tubular, with four small round lobes, twice as long as the calyx, the emarginate segment broader than the others. Stamens two, as long as the corolla, inserted on the tube near the base of the upper segment. Anthers erect, two-lobed, pale-purple. The ovary is superior, 39 610 Materia Medica. quadrangular, somewhat furrowed, with a filiform style, somewhat exserted, and terminated by a two-cleft stigma, the lobes of which are acute. Seeds four, longer than the calyx, obovate, compressed, and crenate at the top. History.—Bugleweed is found growing throughout the greater part of the United States, in moist and shady situations, flowering in July and August. It has a peculiar, balsamic, terebinthinate odor, and a disa- greeable, slightly bitter taste. It imparts its properties to boiling water in infusion. The whole herb is officinal. It has not been analyzed, but, probably, its virtues depend upon a volatile oil and tannic acid. Properties and Uses.—The exact medicinal virtues of this plant are not fully understood. It appears to possess sedative, tonic, astringent, and narcotic properties, and has been successfully used in incipient phthisis, hemoptysis, and other hemorrhages ; it allays irritation, dimin- ishes the frequency of the pulse, and lessens cough. It acts somewhat like digitalis, in abating the velocity of the pulse, but is devoid of the dangerous effects resulting from the use of that drug. It is peculiar to Eclectics in the treatment of diabetes, haA7ing cured when all other means were useless; and has been beneficial in chronic diarrhea and dysentery, inflammatory diseases of drunkards, diseases of the heart, and intermittents. Dose of the powder, from one to two drachms; of the infusion, from two to four fluidounces. The Lycopus Europeus, a European species, but naturalized in this country, has long been employed as a febrifuge ; and the most obstinate intermittents have been cured by two-drachm doses of the dried plant. It is frequently collected and sold for L. Virginicus, but may be distinguished by its acutely quadrangular stem, its narrow lanceolate leaves of Avhich the lower are somewhat pinnatifid, its more crowded floAvers, and the acute segments of its calyx, armed with short spines.

Description.—This plant, also known by the name of Purple-willow- herb, is an elegant perennial, with a woody root, sending up several erect, leafy, slender, reddish stems, three or four feet high, downy, herbaceous, quadrangular, or even hexangular near the root. The leaves are mostly opposite, occasionally in whorls of three or four, in which cases the number of angles in the stem is likewise in- creased ; they are also nearly sessile, lanceolate, acute, entire, from Lythrum Salicaria. 611 three to six inches in length, and about one-fourth as wide, the upper ones diminished to bracts, cordate at the base, and downy on the under surface, and at the margin. The flowers are large, numerous, nearly sessile, inodorous, purple, axillary, crowded and whorled in a ter- minal, interrupted wand-like spike, six in each whorl. The calyx is inferior, cylindrical, striated, downy or hairy, with twelve marginal teeth, six of Avhich are long, subulate, erect, and reddish ; the others minute, ovate, concave, and inflected. The petals are six, elliptic-oblong, equal, waved. Stamens twelve, filiform, the six alternate ones shorter, bearing red, roundish anthers, with green or yellow pollen. The ovary is ovate- oblong, with a simple style and capitate stigma. The capsule is small, elliptical, two-celled, many-seeded, and inclosed in the tube of the calyx. History.—This plant is found in various parts of the world, being an inhabitant of Europe, Asia, North America, and New Holland, growing in wet situations, and in this country bearing purple flowers in July and August. It is inodorous, but has a herbaceous, mucilaginous, some- what astringent taste. It yields its properties to water. It has not been analyzed, but probably contains tannin and much mucilage. It renders boiling Avater very mucilaginous, and its decoction is blackened by sul- phate of iron. Properties and Uses. — Demulcent and astringent. Very useful in diarrhea, dysentery, and other affections of the bowels, where this class of remedies is indicated ; used freely in decoction. Externally, it is very beneficial as a local application in ophthalmia, leucorrhea, gleet, ulcers, and some forms of cutaneous disease ; used either as a wash, or in form of poultice. Dose of the powder, one drachm, two or three times a day; of the decoction, one or two fluidounces. The Decodon, or L. Verticil- latum, or Swamp Willow-herb, bearing purple flowers, possesses similar properties to the above; it is said to cause abortion in mares and cows browsing it in winter, and may, perhaps, exert a medicinal influence on the female uterus. It groAvs in swamps throughout the United States and Canada, has a stem woody at the base, often prostrate, and rooting at the summit, three to eight feet long, or when erect from two to three feet in hight, and from four to six-angled. The leaves are opposite, or in whorls of three, lanceolate, on short petioles, acute at base, from three to five inches long, gradually acuminate and acute at apex. The flowers are large, purple, in axillary subsessile umbels of three or more, appa- rently whorled, constituting a long, leafy, terminal and showy panicle. Calyx short, broadly campanulate, with five erect teeth, and five elon- gated, spreading, horn-like processes. Petals five or six. Stamens ten, alternate ones very long; style filiform ; capsule globose, included, three- celled, many seeded. Off. Prep.—Decoctum Lythri. 612 Materia Medica. MAGNESIA. (Magnesia Usta.) Magnesia. Preparation.—Magnesia, or Calcined magnesia, as it is more usually termed, is obtained by placing carbonate of magnesia in an earthen vessel, and exposing it to a red-heat for two hours, or until all the car- bonic acid is expelled, by which process the earth is obtained pure. A very intense heat is not required for the calcination, but merely sufficient to expel the water and carbonic acid; if a higher heat is kept up, the magnesia obtained will be hard, dense, less readily soluble in acids, and less beneficial as a medicine. The expulsion of the carbonic acid may be known by mixing a little of the magnesia with water, when on the addition of muriatic acid, no effervescence ensues. History.—Magnesia is a pure white powder, of various degrees of density, obscurely alkaline, inodorous, and of an earthy taste ; it attracts from twelve to twenty per cent, of moisture from the air, passing from the caustic to the slaked condition, but it does not absorb carbonic acid in a corresponding degree. Water sprinkled on it is absorbed to the extent of about 18 per cent., but Avithout heat being evolved, and when thrown into water, it crackles slightly. Its specific gravity is about 2.3. Trituration greatly increases its specific gravity, so that a bottle which wrould only contain one ounce of it when not triturated, will, by this process, readily hold four ounces, or four times the quantity. The density of the magnesia is increased by employing a high temperature during calcination. It is soluble in 5142 parts of water at 60°, in 36,000 parts of boiling water. It unites with acids, occasioning much heat, and forms salts, some of which are soluble; the nitrate and muriate of magnesia are very deliquescent, and soluble in alcohol. It is precip- itated from its saline solutions, in the state of a hydrate, by the pure alkalies, and in the state of a carbonate by the carbonates of soda and potassa; the bicarbonates of alkalies, and ordinary carbonate of ammonia cause no precipitate. Magnesia is a metallic oxide, consisting of one equivalent of magnesium 12, and one of oxygen 8=20, (Mg 0.) Henry's magnesia is usually considered the best; its method of pre- paration is not known; some suppose its softness, density, and ready miscibility with water, to be owing to its being prepared by precipitation of a solution of sulphate of magnesia by caustic potassa ; others suppose the precipitation to be accomplished with carbonate of soda; and others again to the employment of an intense heat. If equivalent quantities of crystallized sulphate of magnesia, and crystallized carbonate of soda be boiled together in water, the mixture evaporated to dryness, the residual salts calcined, and the sulphate of soda dissolved out by water, the magnesia obtained will be dense. Husband's magnesia stands next to Henry's, and Ellis's last. Magnesia is subject to adulteration with lime, alumina, silica, and, Magnesia Carbonas. 613 from careless calcination or preservation, carbonate of magnesia. If carbonate of magnesia be present, the addition of muriatic acid will cause effervescence ; silica may be detected by the same acid, which slowly dissolves the magnesia but does not touch the silica. Alumina may be detected by dissolving fifty grains of magnesia in a fluidounce of muriatic acid,—if alumina be present, ammonia added in excess Avill cause a precipitate of the adulteration. A neutral solution of pure mag- nesia in a dilute acid, is not disturbed by the addition of oxalate of ammonia, or bicarbonate of potassa; but if lime be present, both cause precipitates ; the first of oxalate of lime, the second of carbonate. Ad- herent sulphate of magnesia is indicated in the muriatic solution of magnesia, by the chloride of barium, which precipitates a white sulphate of baryta. Properties and Uses.—Magnesia is antacid, antilithic, and laxatiAre. It is useful in dyTspepsia Avith acidity, and is preferable to the carbonate, as it can be given in a much smaller dose, and does not occasion flatulence ; its laxative qualities likewise give it some advantage over alkaline reme- dies. In all cases attended with acidity and constipation it will be found useful. It acts as an antilithic, first by correcting gastric acidity, and secondly by forming with free lithic acid, or lithate of ammonia, the more soluble lithate of magnesia. It is on this account beneficial in gout, and rheumatic gout, frequently giving material relief. It is apt to lodge in the bowels, if no acid be present, hence, in this case, it should be followed by a draught or two of lemonade. It is often united with rhubarb as a laxative and antacid. Freshly precipitated hydrate of magnesia, is a good antidote to arsenious acid, though inferior to the hydrated peroxide of iron. The following is recommended in cases of poisoning, in which the nature of the poison is unknown: after freely evacuating the stomach by emetics, give the following mixture in a suffi- cient quantity of water—Calcined magnesia, pulverized charcoal, and sesquioxide of iron, of each, equal parts, mixed together. It is per- fectly innocuous, and as its ingredients are antidotes to the most active and commonest poisons, it is very likely to be efficacious. Dose, as a laxative from half a drachm to a drachm; as an antacid, or antilithic, from ten to thirty grains twice a day. MAGNESLE CARBONAS. Carbonate of Magnesia. Preparation. — Carbonate of Magnesia rarely occurs as a native mineral, but is usually prepared on a large scale, by decomposing the sulphate of magnesia with carbonate of soda. Dissolve four pounds nine ounces of carbonate of soda, and four pounds of sulphate of mag- nesia, separately, in two gallons (Imperial measure) of distilled water; mix the solutions, then boil for two hours, constantly stirring it with a 614 Materia Medica. spatula, and adding a little distilled water now and then, so as nearly to preserve the measure; then pour off the liquor, collect the precipitate, wash it thoroughly with boiling distilled water, and dry it. Some of the best manufacturers are said to prepare it according to the following method; a solution of one hundred and twenty-five parts of crystallized carbonate of soda is gradually added to a saturated solution of one hundred parts of sulphate of magnesia, constantly stirring the solutions. The mixture is then heated to ebullition, in order to com- plete the precipitation of the magnesia, which is subsequently washed with tepid, and finally with cold water, until the washings no longer give a precipitate with the salts of baryta. When it is sufficiently washed, the carbonate is allowed to drain for one or two days on large linen filters, and is then placed in wooden molds with a porous bottom of brick or gypsum, and subjected to pressure in order to give it the square and compact form into which it is usually wrought. History.—Carbonate of Magnesia is made, in this country, from the bittern of salt works, which consists principally of sulphate of magnesia, and chloride of magnesium. But the greater part of that used* is im- ported from Scotland, from which place it comes to us in cases of one hundred and twenty pounds each. Officinal Carbonate of magnesia is a pure white powder, loose, and granular if dense, but somewhat coher- ent, like starch, if light,—inodorous, nearly tasteless, smooth to the touch, permanent in the air, and feebly alkaline in its action on vegeta- ble colors. It is soluble in 2493 parts of cold, and 9000 parts of hot water; it is more soluble in cold water if it be charged with carbonic acid, forty-eight parts of water being then sufficient. It is soluble in diluted nitric, muriatic, sulphuric, or carbonic acids, and effervescence takes place. It is decomposed by strong heat, all the acids, potassa, soda, lime, baryta, strontia, the sulphate, phosphate, nitrate, or muriate of alumina, and by acidulous or metallic salts. There are two kinds of this salt in commerce, the light and the heavy. Its density is said to depend upon the strength of the solutions from which it is first precipitated, and its fineness and softness to the touch, upon the use of carbonate of soda in its preparation. The light carbo- nate is the kind manufactured in Scotland. Carbonate of magnesia varies in its composition with the mode of preparation. Berzelius, whose doctrine is most current, supposes it to be a compound of three equiva- lents of the hydrated neutral carbonate, with one equivalent of hydrated magnesia. According to Phillips, four equivalents of the carbonate are combined with one of the bi-hydrate, and four of water. The impurities of carbonate of magnesia, are similar to those of mag- nesia, and usually occur from carelessness in the process of manufac- turing. If water in which carbonate of magnesia is boiled changes turmeric paper, it contains an alkaline carbonate. If chloride of barium Magnesije Sulphas. 615 causes a precipitate in the water, it indicates the presence of a sulphate, or carbonate, or both. If nitrate of silver produces a precipitate, a chlo- ride is present, probably of sodium. Alumina is separated from the muriatic acid solution by an excess of ammonia — the solution to be made in an excess of the acid. And after the alumina has been thrown down, if lime be present, the addition of oxalate of ammonia will cause a precipitate of oxalate of lime. Properties and Uses. — Carbonate of Magnesia is antacid, antilithic, and by combining with acid in the stomach, it becomes generally cathar- tic ; but produces no purgative effect, if it undergoes no change in the alimentary canal. Hence, it is always useful to give it in combination with lemonade or lemon juice. Useful in cases of acid stomach, gout, and where the urine contains an excess of uric acid ; but from its lia- bility to produce flatulence, in consequence of the extrication of its carbonic acid in the stomach and bowels, it is inferior to the calcined magnesia. Dose, as an antacid and antilithic, one or two scruples ; as a cathartic, one or two drachms in water or milk. It is a useful agent for diffusing camphor and volatile oils through water in preparing several of the medicated waters. Off. Prep.—Liquor Magnesia Citratis. MAGNESLE SULPHAS. Sulphate of Magnesia. (Epsom-Salts.) Preparation. — Sulphate of Magnesia, commonly known as Epsom- Salts, is one of the constituents of sea water, and of some saline springs. For its artificial manufacture, several processes are followed, the most important of Avhich are as follows :—When prepared from bittern water, or the residual brine after crystallizing salt from sea water, it is accom- plished by simple evaporation and crystallization. A little sulphuric acid is added to the bittern in order to convert the chloride of mag- nesium, which forms part of its saline ingredients, into the sulphate. It is then carefully evaporated, and the sulphate of magnesia crystallizes first, leaving behind the chlorides of magnesium and calcium. It is then collected, and any impurities it may contain removed by washing the crystals in water, or by chemically precipitating the impurities, filtering, and evaporating. However, the sulphate of magnesia obtained by this process is very apt to be impure and deliquescent. It is also prepared from dolomite, a magnesian limestone, composed of carbonate of lime and carbonate of magnesia ; the carbonates may be converted into sulphates, and the latter separated by means of the infe- rior solubility of the sulphate of lime. Or the dolomite may be calcined, thereby driving off the carbonic acid, and converting the remaining earths into hydrates ; then muriatic acid is added in such quantity as to 616 Materia Medica. unite with the caustic lime only, and the chloride of calcium being re- moved by solution in water the magnesia is converted into the sulphate by means of sulphuric acid. It is likewise prepared from magnesite, a siliceous hydrate of magnesia, which is found in veins in the serpentine and other magnesian rocks so common in the neighborhood of Baltimore and southern Pennsylvania. This mineral is finely powdered, and the powder saturated with sulphuric acid. The whole mass is then dried and calcined at a red-heat, for the purpose of changing any existing sul- phate of iron into red oxide. It is then dissolved in water, and sulphuret of lime added to separate any remaining portion of iron. The salt is crystallized and dissolved a third time in order to purify it. In this manner sulphate of magnesia is extensively prepared at Baltimore, and is usually very pure and clean. Sulphate of magnesia also occurs as a native production, being found abundantly in many of the great caverns of the western states. It is found in long, slender, prismatic crystals; as an efflorescence on certain rocks and soils, or it occurs in masses of six, eight, or ten pounds. History.—Sulphate of Magnesia was discovered in 1694 by Grew, who prepared it from the saline waters of Epsom in England, from whence it has derived its familiar name, Epsom-Salts ; at present it is usually met with in small acicular crystals, transparent and colorless, inodorous, of a cooling, saline, bitter, disagreeable taste, and slightly efflorescent in dry air. When slowly crystallized it forms large rhombic or quadran- gular prisms, often truncated on the obtuse edges, and terminated by two or four converging planes, somewhat like the crystals of sulphate of Zinc, and sulphate of Soda. A moderate heat causes it to fuse in its water of crystallization; a higher temperature renders it anhydrous; and at a full red-heat the anhydrous salt melts into an enamel. It is insolu- ble in alcohol, soluble in its own weight of water at 60°, and in three- fourths of its weighj; at 212°. It is decomposed by potassa, soda, and their carbonates; by lime, baryta, strontia, and their soluble salts. Am- monia partially decomposes it, forming with the remaining salt a double sulphate. The bicarbonates of potassa and soda, decompose it by the aid of heat. It consists of one equivalent of acid 40, one of base 20, and seven of water 63=123, its combining number. (Mg 0+S03 +7 Aq.) This salt is liable to various impurities, but as now prepared is gener- ally quite free from them. Iron, and chloride of magnesium are, pro- bably, the most common impurities at present met with. Iron may be detected by ferrocyanuret of potassium, and the chloride of magnesium by rendering the salt moist. If sulphuric acid be added to the sulphate, and muriatic acid gas is not evolved, the absence of all chlorides is indi- cated. To detect the presence of sulphate of soda, ten grains of the salt are to be dissolved in a fluidounce of water, and treated with a solu- tion of sesquicarbonate of ammonia; 280 minims of a solution of one Magnolia Glauca. 617 part of phosphate of soda in twenty parts of water are then added, which precipitates 97 per cent, of the magnesia in a pure sulphate, leaving a little magnesia in the solution. Filter the solution, and add to it more of the phosphate of soda solution, if no more magnesia is thrown down, the salt must contain something else than sulphate of magnesia. Properties and Uses.—Refrigerant, cathartic and diuretic. Chiefly used in febrile and inflammatory affections, or in cases where a refriger- ant, mild laxative effect is desired. It may be dissolved in eight times its quantity of water. The addition of four or five drops of sulphuric acid to the dose covers the bitter taste of the salt, causes it to sit easier on the stomach, counteracts its refrigerant effects, does not impair its energy, completely removes its tendency to gripe or irritate the rectum, and prevents it from interfering with the appetite or diges- tion. M. Combes states that the bitterness of this salt may be removed, by the following means : Take of Sulphate of Magnesia, one ounce, powder of roasted coffee, two and a half drachms, water about sixteen ounces. Place in a A7essel (not a tin one), and boil for two minutes, remove from the fire, and let the mixture infuse for some minutes, so as to allow time for the development of the aroma; then strain and sweeten to the taste. By this process the salt is not decomposed. Should it be required to increase the amount of the sulphate without augmenting the proportion of coffee, two or three grains of tannic acid should be added to the boiling decoction. Dose of the powder, from two drachms to two ounces. Very seldom used by Eclectics. MAGNOLIA GLAUCA. Magnolia. Nat. Ord.—Magnoliaceaa. Sex. Syst.—Polyandria Polygynia. THE BARK. Description.—This tree is known by several names, as White bay, Beaver-tree, Sweet Magnolia, Swamp Sassafras, etc. In the Northern States it is often nothing more than a shrub, from four to ten feet high ; in the south it often attains the hight of forty feet. Its average hight is about twenty-five feet. The trunk is covered with a smooth grayish bark, and that of the young twigs is a bright, smooth green, scarred with rings at the insertion of the leaves by the fall of the deciduous stipules; the branches are crooked and much divaricated. The leaves are alternate, petiolate, oval, obtuse, entire, coriaceous, smooth, thick, opake, yellowish-green on their upper surface, and with the exception of the midrib, of a beautiful pale glaucous color beneath; when young they are covered with a silken pubescence. The flowers are large, solitary, terminal, cream-colored, of a grateful odor, and stand on a short incrassated peduncle. The calyx is composed of three, spathulate, obtuse, concave sepals; the corolla consists of from 618 Materia Medica. eight to fourteen, obovate, obtuse and concave petals, which are con- tracted at their base. The stamens are very numerous, and are inserted in common with the petals on the sides of a conical receptacle ; filaments very short; anthers linear, mucronated, two-celled, opening inwardly. Ovaries collected into & cone, each divided by a furrow, and tipped Avith a brownish, linear, recurved style. Fruit a small, squarrose, fleshy cone, about an inch in length, of a green color tinged with red. These cones consist of numerous imbricated cells, each contain- ing a bright red seed, and open longitudinally at the back for the escape of the seed. The seeds are obovate, and on the opening of the capsule at maturity, are connected to the cone by a funiculus, or Avhite slender thread formed of spiral vessels, which suspends them for some time after they have fallen out. The M. Glauca is found growing in swamps and morasses along the seaboard, from Massachusetts to the Gulf of Mexico, and is seldom met with at any great distance from the seaboard. It flowers in May, June, or July according to the latitude. At the south it is known as White bay, or Sweet bay. The fragrance of its flowers is usually agreeable, but to some persons it is not only unpleasant, but absolutely deleterious, causing oppressed breathing and faintness. Magnolia Acuminata, or Cucumber Tree, is much larger than the preceding, often growing to the hight of sixty or eighty feet, with a diameter of from four to six feet. The leaves are oval, acuminate, pubescent beneath, five or six inches in length by three or four in breadth. The fiowers are five or six inches in diameter, bluish, some- times yellowish-white, slightly odorous, with from six to nine obovate, rather obtuse petals. The cones are about three inches long, cylindric, bearing some resemblance to a small cucumber. This tree grows near the Falls of Niagara, and in the mountainous regions in the interior of the country from New York to Georgia; it is more abundant in the Southern States. Its flowers appear in May and June. Magnolia Tripetala, or Umbrella Tree, the M. Umbrella of Lamark, is a small tree not exceeding thirty feet in hight, and almost always having an inclined trunk. Its leaves are from sixteen to twenty inches long, by six or eight in width, thin, obovate, somewhat wedge-shaped, entire, acute at both extremities, silky when young, and often appear- ing whorled at the ends of the branches in the form of an umbrella, displaying a surface thirty inches or more in diameter. The fiowers are terminal, white, seven or eight inches in diameter, with from five to twelve, narrow lanceolate, acute petals, of which the three outer are reflexed. The fruit is conical, rose-colored, and from four to five inches in length. This tree is found growing in shady situations, in strong, deep, fertile soil, in the same range of country as the M. Acuminata, being, however, more generally confined to the lower grounds. It also flowers in May and June. Malva Sylvestris. 619 History.—All the species of Magnolia are possessed of similar medici- nal virtues, which are found in the bark and fruit. The bark only is officinal, and that of the root is considered the most efficient, though probably without much reason. It has an aromatic odor, and a spicy, bitter, pungent taste, without any astringency. When dried, or by long keeping, its volatile aromatic principle is much diminished, but without any loss of its bitterness. It has not been analyzed but probably con- tains volatile oil, resin, and magnolin. Water or alcohol extracts its virtues. Properties and Uses.—Magnolia Bark is an aromatic tonic bitter of considerable power, and appears likewise to possess antiperiodic proper- ties. Intermittent fevers have been cured by it after cinchona had failed. It is not so apt to disagree with the stomach and bowels, nor to induce fullness of the head as the Peruvian bark, and can be continued a longer time with more safety in all respects. Its curative agency is said to be favored by the diaphoretic action which generally follows its administra- tion. In dyspepsia, vrith loss of tone in the stomach, it is very useful as a tonic, and has also proved highly beneficial in the treatment of remit- tents having a typhoid character. A warm infusion acts as a gentle laxative and sudorific ; a cold one as a tonic and antiperiodic, -as does also the tincture and powder. The powder is considered the preferable form of administration. The bark of the M. Tripetala, cheAved as a substitute for tobacco, has cured an inveterate tobacco cheAver of the filthy habit, and deserves a further trial among those who wish to break up the pernicious practice. The bark in powder may be administered in half drachm or drachm doses, to be repeated five or six times a day ; the infusion may be taken in wineglassful doses, repeated five or six times a day. It is used in the above forms of disease, as well as in chronic rheumatism. The tincture, made by adding an ounce of the powder to a pint of brandy, and allowing it to macerate for ten or twelve days, may be given in tablespoon doses three times a day, for the same purposes. A tincture made by adding two ounces of the cones to a pint of brandy, has long been used as a domestic remedy for dyspepsia and chronic rheumatism; it is given three or four times a day in doses of from one to four fluidrachms. Magnolia is contra-indicated whenever inflammatory symptoms are present. MALVA SYLVESTRIS. Common Mallow. Nat. Ord.—Malvaceaa. Sex. Syst.—Monadelphia Polyandria. THE HERB. Description.—This is a perennial herbaceous plant, sometimes called High-mallow; it has a tapering, branching, whitish root, and a round, hairy, branching, usually erect stem, from one to three feet in hight! 620 Materia Medica. The leaves are alternate, petiolate, cordate, deep-green, soft and downy, serrated, plaited, with seven acute lobes ; the uppermost Avith fewer, but deeper, and more acute lobes, than the lower ones. The fiowers are large, numerous, of a shining purple, veiny, on simple, aggregate, hairy axillary stalks. The calyx is five-cleft. Petals five, inversely cordate, and three times as long as the calyx. Stamens, indefinite, mon- adelphous. Pollen large, whitish. Ripe carpels reticulated at the back. Malva Rotundifolia, or Low-mallow, called by children who are fond of eating the fruit, cheeses, has a fusiform root and prostrate stem, with leaves of a fine, delicate texture, roundish, cordate, or somewhat uniform, crenate, obtusely five or seven-lobed, and on long hairy petioles. The fiowers are pale-pink, with deeply-notched petals, and stand on aggregate, axillary peduncles. The fruit is depressed-globose, and composed of the numerous carpels arranged circularly. History.—The M. Sylvestris is a native of Europe, and is naturalized in this country, growing abundantly in fields, roadsides, and waste places, and flowering from May to October. The whole plant, especially the root, abounds in mucilage. The M. Rotundifolia, a very common, troublesome plant growing around dwellings and in cultivated grounds, together with other species of this genus, possesses similar properties, and may be substituted for each other. The herb and flowers are inodorous, with a weak, herbaceous, mucilaginous taste. Water extracts their mucilage, and the solution is precipitated by acetate of lead. The root and seeds may be also used, as they contain much mucilage. An infusion or tincture of the flowers is blue, and is turned red by acids, and green by alkalies, and may hence be used as tests for these articles. Properties and Uses. — Emollient and demulcent. Infusion and decoction used in catarrhal, dysenteric and nephritic complaints. Also used as an emollient injection, and the herb in the form of poultice to external inflammations. They may be employed in all cases where mucilaginous liquids are required. MARANTA ARUNDINACEA. Arrowroot Plant. Nat. Ord.—Marantaceaa. Sex. Syst.—Monandria Monogynia. THE FECULA OF THE RHIZOMA, ARROWROOT. Description.—The root or rhizoma of this plant is perennial, tuberous, fleshy, horizontal, nearly cylindrical, scaly, from six inches to twelve, or more, in length, and furnished with numerous long white fibers. It sends forth several tuberous, jointed, curved, white, scaly stoles, the points of which sometimes rise above the ground, and become new plants. The stems are several, annual, slender, much branched, finely hairy, jointed, leafy, and about two or three feet in hight. The leaves Maranta Arundinacea. 621 are -alternate, with long, leafy, hairy sheaths, ovate, lanceolate, slightly hairy underneath, pale-green on both sides, and about four inches long. The fiowers are white, and disposed in a long, loose, spreading, terminal panicle, with long linear sheathing bracts at the ramifications. Calyx green, smooth, and consists of three small lanceolate leaves. Corolla white, small, monopetalous, with a tube longer than the calyx, and a double border, of which the three outermost segments are smallest, and the two inner obovate, and slightly emarginate. Ovary three-celled, hairy. Fruit nearly globular, with three obsolete angles, the size of a small currant. History.—This plant is a native of the West Indies, from which it has been introduced and cultivated in the East Indies, in Sierra Leone, and in our Southern States. The plant is readily propagated by cuttings of the root. Arrowroot is obtained from the various portions of the root, which are dug up when a year old, washed, beaten into a pulp, and stirred in cold water; the fibers are removed by the hand, and the milky liquor, which holds the starch suspended, is passed through a fine sieve, the starch allowed to subside, and then after washing it with a fresh portion of water, it is dried without heat, or in the sun. This constitutes West Indian arrowroot, of which the finest comes from the Bermudas. Arrowroot is obtained likewise from other plants, as the M. Allouya, and M. Nobilis of the West Indies ; the M. Indica, and the Curcuma Anguslifolia of the East Indies. West Indian arrowroot is in the form of a light white powder, or of small, irregular, friable grains varying in size from a millet seed to a pea. It is inodorous, nearly tasteless, has a firm feel when pressed between the fingers, and when rubbed produces a faint crackling sound. If musty, it should be rejected. Musty arrowroot, having been thoroughly washed with two successive portions of cold water, and then dried upon frames of muslin in a warm place, has been rendered quite sweet. Examined by the microscope, arroAvroot is found to consist of minute pearly globules or granules, which are rarely spherical or ovate, generally elliptical, sometimes of the form of a levigating muller, and of various sizes. A few attain the 750th of an inch, and many are only the 2000th of an inch in their longest diameter; their breadth is generally two-thirds of their length. Arrowroot presents all the chemical relations of wheat and potato starch, though it makes a firmer jelly with the same quantity of boiling water, nine parts in this respect being equivalent to fourteen of common starch. According to Prout, anhydrous arrowroot is composed of 44.0 per cent. of carbon, 6.22 of hydrogen, and 49.78 of oxygen or C12 H10 O10, corresponding with the elementary composition of amylin, one of the principles of wheat starch. West Indian arroAvroot is sometimes adulterated with Avheat or potato starch, or with the East Indian variety of arrowroot. Muriatic acid has been proposed as a test of their presence. When potato or wheat starch 622 Materia Medica. is rubbed with twice their weight of a mixture of equal parts of muriatic acid and water, a mucilage is quickly formed so thick and tenacious that the mortar in which the trituration is effected may be raised by the pestle ; with rice flour, or arrowroot, this result does not ensue short of 25 or 30 minutes. It is said that from four to six per cent, of the impu- rity may thus be detected. But the microscope affords the best means of determining these adulterations, by observing the form of their granules. Thus the true arrowroot granules are rarely oblong, somewhat ovate- oblong, or irregularly convex, with very fine rings, a circular hilum which cracks in a linear or stellate manner, and small mammillary pro- cesses occasionally projecting from them. (See above for size, etc.) The East India arrowroot granules are of unequal size, ovate or oblong- ovate, flattened, and often furnished with a very short neck or nipple- like projection; the rings are numerous, close, and very fine, and the hilum, which is situated at the narrow extremity, is circular, small, and indistinct. (See description of Tapioca.) The Tacca Fecula from the South Sea islands, consists of circular, mullen-shaped, or polyhedral granules, Avith few and not very distinct rings, and a small, circular hilum, which is cracked in a linear or stellate manner. Florida arrowroot consists of granules forming the half, the third, or the quarter of a solid sphere. The potato-starch granules are very unequal in size, ovate, or for the most part elliptical, and from the 7000th to the 300th of an inch in length. (See Canna.) East Indian arrowroot, is chiefly prepared from a plant growing throughout India, and particularly on the Malabar coast, the Curcuma Angustifolia; it is prepared by a process similar to that followed in the West Indies. It is commonly white, sometimes pale-yellow, less crepi- tating between the fingers than the best West Indian kind, more fre- quently damaged by impurities, and composed of rather larger globules, unequal in size, egg-shaped, compressed, faintly rugous at their larger end, and with little processes attached to their sides. It is lighter than maranta arroAvroot, does not so quickly make a jelly, and is of low value, being in demand only among starch-makers. Properties and Uses.—Arrowroot is nutritive and demulcent. Used as an article of diet in certain chronic diseases, during convalescence from fevers, bowel complaints, diseases of the urinary organs, and for infants after weaning. It may be given in the form of jelly, variously seasoned with sugar, lemon juice, fruit jellies, essences or aromatics. Potato starch is sometimes substituted for it, but it is more apt to cause acidity. Arrowroot is superior to every other kind of farinaceous food, except tapioca and tous-les-mois. Its jelly has no peculiar taste, and is less liable to become acid in the stomach, and is generally preferred by young infants to all others, except tapioca. Tous-les-mois makes a stiffer jelly. A tablespoonful of arrowroot may be formed into a paste with a little cold water, and then enough boiling water gradually added Marmor Album — Makrubium Vulgare. 623 with brisk agitation to make a pint. It may be seasoned with any of the above-named articles if not contra-indicated. For children it is usually prepared with milk. MARMOR ALBUM. White Marble. WHITE GRANULAR CARBONATE OF LIME. History.—White Marble is known from most other minerals by its pure white color, its crystalline structure, and the effervescence it presents when touched with nitric or muriatic acids. It is tasteless, inodorous, brittle, pulverizable, and insoluble in water or alcohol. Its specific gravity varies from 2.7 to 2.8. When exposed to a full red-heat, it acquires an earthy appearance, loses about 44 per cent, of carbonic acid, and is converted into lime. It dissolves less rapidly in acetic acid than in nitric or muriatic ; it also dissolves with effervescence in sulphuric acid, and forms an insoluble salt. When pure it consists of one equiva- lent of acid or 22.12 parts, and one of lime, or 28.5 parts (Ca O+CO2.) It is sometimes rendered impure by the presence of magnesia. To detect this, the marble must be dissolved in diluted muriatic acid, taking care that the marble neutralizes the muriatic acid, or else the magnesia will not be thrown down on account of the formation of muriate of am- monia. To this neutral muriatic solution add ammonia, and if magnesia be present, it will be precipitated. If strontia or baryta be an impurity, a solution of sulphate of lime will cause a precipitate. Properties and Uses.—Marble is used for obtaining acid, as well as for making several officinal preparations. Common marble is sufficiently pure for the former purpose, but not for the latter. The Dolomitic marbles contain considerable proportions of magnesia, and are therefore unfit for pharmaceutic use. The finest and purest variety of marble is that of Carrara, sometimes called Statuary Marble. Off. Prep. — Aqua Acidi Carbonici; Potassa Bicarbonas; Soda Bicarbonas. MARRUBIUM VULGARE. Hoarhound. Nat. Ord.—Lamiaceaa. Sex. Syst.—Didynamia Gymnospermia. THE HERB. Description.—Hoarhound has a perennial fibrous root, and numerous, annual bushy stems, which are erect, quadrangular, leafy, clothed with fine woolly pubescence, branching from the bottom, and from one to two feet in hight. The leaves are roundish-ovate, crenate-dentate, wrinkled, veiny above, hoary on the under surface, one or two inches in diameter and supported in pairs upon strong footstalks; the upper ones nearlv 624 Materia Medica. sessile. The fiowers are small, white, in sessile, axillary, hairy, and dense whorls. The calyx is tubular, five to ten-nerved, nearly equal, with five or ten recurved, acute, spiny teeth, the alternate ones shorter; orifice of the tube, hairy. The corolla is tubular, with a labiate margin, of which the upper lip is bifid, the under reflected and three-cleft, with the middle segment broad, and slightly scolloped. Stamens four, didy- namous, included beneath the upper lip of the corolla; anthers with divaricating, somewhat confluent lobes, all nearly of the same form. Style with short obtuse lobes. Achenia obtuse. Seeds four, lying in the bottom of the calyx. History.—This plant is a native of Europe, but has been naturalized in some parts of the United States. It grows on dry, sandy fields, waste grounds, road-sides, and banks of rubbish, especially in warm, dry situ- ations, and flowers in July and August. The whole plant has a white, hoary appearance. The whole herb is officinal, it has a peculiar, rather agreeable, vinous, balsamic odor, and a very bitter, aromatic, somewhat acrid, and persistent taste. Its bitterness is extracted by alcohol or water. It contains resin, tannic acid, volatile oil, a peculiar crystalliza- ble bitter principle, and lignin. The bitter principle is insoluble in water, soluble in ether, more so in hot than cold alcohol, is perfectly neutral, and melts like resin when heated. Properties and Uses.—Hoarhound is a stimulant tonic, expectorant, and diuretic. It is used in the form of syrup, in coughs, colds, chronic catarrh, asthma, and all pulmonary affections. The warm infusion will produce diaphoresis, and sometimes diuresis, and has been used with benefit in jaundice, asthma, hoarseness, amenorrhea, and hysteria; the cold infusion is an excellent tonic in some forms of dyspepsia, acts as a vermifuge, and will be found efficacious in checking mercurial ptyalism. In large doses it purges. It enters into the composition of several syrups and candies. Dose of the powder, one drachm; of the infusion, or syrup, from two to four fluidounces. Off.

Description.—Maruta Cotula has an annual, crooked, tapering, fibrous root, with one or more stems, erect, branched, bushy, leafy, angular, furrowed, nearly smooth, solid, and rising from one to two feet high. Branches corymbose. Leaves alternate, sessile, bright-green, smooth, or slightly hairy, bipinnatifid and cut; the segments narrow, flat, a little • Mel. 625 succulent, spreading and rather distant, not crowded or parallel, some- what bristle-pointed. Flower-heads solitary, on terminal, striated, slightly downy peduncles. Involucre hemispherical, imbricated, hairy, rouo-h ; the scales linear, pale-green, scarious on the margin. Florets of the disk, brio-ht-yellow, numerous; those of the rays Avhite, ligulate. Receptacle conical, covered Avith short, bristly chaff. Central florets tubular, glandular, five-toothed, Avith five-stamina. Ovary obovate, with a filiform, bifid style.'' Stigmas two, reflexed. Seeds brown, obovate, quadrangular, ribbed. History.—Mayweed is a native of Europe, and is extensively culti- vated in this country, where it is known by several other names, as Wild Chamomile, Dog-fennel, etc. It may be found growing in all waste places, in hard, dry soils, especially along road-sides. Its flowers are white, and appear from June until September. Every part of the plant is acrid and fetid, and according to Linnaus is grateful to toads, drives away fleas, and is annoying to flies. The whole plant is officinal. Properties and Uses.—Tonic, emetic, antispasmodic, emmenagogue and epispastic. The cold infusion or extract may7 be substituted, as a tonic and antispasmodic, in all cases, for the foreign article. The extract may be used in sick headache, and in convalescence from fevers. A warm infusion may be used as an emetic or diaphoretic. It has been efficient in amenorrhea. The fresh plant bruised and applied to the skin, will cause vesication, and the sores heal readily. A powerful epispastic is made by bruising the fresh leaves of M. Cotula and Poly- gonum Punctatum, equal parts, and moistening them with a small quan- tity of spirits of turpentine. Dose of the infusion, from one to four fluidounces, as often as required. Off. Prep.—Infusum Anthemidis Cotula. MEL. Honey. A LIQUID PREPARED BY APIS MELLIFICA. History.—The Apis Mellifica, or honey bee, belongs to the order Hymenoptera of the class of insects. In the wild state it dwells in the hollows of trees in large communities, consisting of males, females, and neuters. The neuters only collect honey, they suck it from the nectaries of flowers by means of their proboscis, convey it into a proper recep- tacle, and discharge it into the cells of the honeycomb, somewhat altered in its sensible qualities. It is yet undetermined, however, whether honey is a secretion of the bee, or exists already-formed in the plant. The nectaries of flowers, it is well known, contain a saccharine substance, which is taken up by the insect, and the honey formed is also affected in its flavor and character by the nature of the plants which predominate 40 626 Materia Medica. in the vicinity of the hive—yet some change is undoubtedly undergone in the organs of the bee, as there is an appreciable difference between the saccharine matter of the nectaries and honey. Honey of a superior quality is obtained by7 allowing it to drain from the comb; and if it be from a hive of young bees before they have swarmed, it is called Virgin honey. After the first honey is collected, an inferior quality is procured by submitting the comb to pressure, or by fusion in the vapor-bath. The greater proportion of the honey used in the^maritime towns and cities of this country is imported from Cuba; though large quantities of it are collected at home. At first honey is fluid, thick, viscid, colorless, or of the palest straw tint, of a peculiar fragrant odor, and of a corresponding, very sweet taste. On being kept it forms a crystalline deposit, and ultimately becomes concrete from the formation of numberless granular crystals. Its flavor varies according to the flowers from which it was collected, and its specific gravity is about 1.333. In a great measure it is soluble in water, and not so readily soluble in alcohol. Boiling alcohol dissolves it, and on cooling deposits crystals of grape sugar. It is said to contain crystallizable sugar analogous to that of grapes, and two other kinds of sugar, one of which is changed by acids, and has the property of turn- ing the rays of polarized light to the right; and the other, not acted on by acids, and possessed of a strong left-handed rotating power. Of these two sugars, the first is not always present in honey, as it is sup- posed to be changed, in time, into granular sugar; it is more abundant in honey taken from the comb. The second is similar to that uncrystal- lizable sugar formed by the reaction of acids on cane sugar, being iden- tical with it in composition, like it uncrystallizable, and very sensitive to the action of alkalies; but differs by the impossibility of converting it into granular sugar, and by having nearly twice the rotating power of com- mon uncrystallizable sugar. Beside these saccharine principles, honey also contains an aromatic principle, an acid, wax, and a little mannite. Diluted with water honey undergoes the vinous, fermentation, and if yeast be added it forms the alcoholic liquor called Mead; nitric acid converts it into oxalic acid. Inferior honey contains a large proportion of uncrystallizable sugar and vegetable acid. Honey is occasionally adulterated with starch, especially the inferior kinds, in order to give them a white appearance. This may be detected by7 diluting with Avater, which dissolves the honey and leaves the starch at the bottom of the vessel. The tincture of iodine will determine the nature of the deposit. Sometimes water is added to increase its bulk, which may be known by the great thinness of the honey, and its tardiness to crystallize. If not very pure, honey is apt to ferment in warm weather, acquiring a deeper color and a pungent taste. Mel despumatum or clarified honey is generally obtained from the inferior qualities; the process of clarification is entirely unnecessary Melia Azedarach. 627 with fine honey. It may be purified by melting the honey by means of a water-bath, the Avax and other light impurities float to the surface, and may be skimmed off, while the heavier substances, if present, sink to the bottom, from which the honey may be decanted. The French clarify honey as follows : Take of honey 3000 parts, water 750 parts, powdered and washed carbonate of lime 96 parts. Mix them in a suit- able vessel, and boil for three minutes, stirring constantly. Then add 96 parts of animal charcoal previously washed, heated to redness, pow- dered and sifted, and boil for a few minutes. Lastly, add the whites of two eggs beat up with 500 parts of water, and bring the liquid to the boiling point. Remove the vessel from the fire, and after the liquid has cooled for fifteen minutes, strain it through flannel, and repeat the straining till the liquid passes perfectly clear. Should it not have the proper consistence, it should be sufficiently concentrated by a quick boiling. The use of the carbonate of lime is to saturate any acid in the honey which might favor the formation of glucose, and thus increase the tendency to granulation. Properties and Uses. — Honey is nutritious, antiseptic, diuretic, and demulcent. Used in urinary affections, and as an addition to gargles, lotions, injections, etc. It is said that the Indians make an infusion of the honey bee, and give a gill of it every half hour, in strangury, sup- pression of urine, etc.; and it is further added, that this infusion has the power of destroying the sexual propensity. A very excellent prepara- tion for coughs, especially during febrile or inflammatory attacks, is composed of honey, olive oil, lemon juice, and sweet spirits of nitre, of each, one fluidounce; to be taken several times a day, in half fluidrachm or fluidrachm doses. A tincture of honey bees is made by collecting a quantity of the living insects in a vial, agitating them roughly so as to irritate them, and while in that condition they are to be covered with alcohol; in a few days it will be ready for use. In doses of five, ten, or fifteen drops, three or four times a day, this is highly recommended in many diseases of the bladder and kidneys, as well as in some uterine affections. Some practitioners assert that it will produce abortion in the pregnant female, if its use be too long continued, or when employed too freely. Off.

Description.—This is a beautiful tree, also known by the names Bead- tree, Pride of India, etc.; it attains the hight of thirty or forty feet, with 628 Materia Medica. a trunk fifteen or twenty inches in diameter, and spreading branches. The bark on the trunk and large branches is scabrous. The roots are horizontal, rather superficial, and extend to a considerable distance. The leaves are large, alternate, unequally bipinnate; the leaflets opposite, smooth, ovate, acute, denticulate, dark-green, with an odd one at the end. The flowers are fragrant, of a lilac-color, forming a terminal, drooping panicle, from the axils of the upper leaves. The calyx is very small, and is formed of five obtuse, slightly-pubescent sepals, united at base. The petals are five, pale-pink inside, deep lilac outside, much longer than the calyx, spreading, oboval, and obtuse. The stamens are united into a tube, which is rather shorter than the petals, dilated at base, of a dark-violet color, and ten-toothed; each tooth being bifid, it appears twenty-toothed, except on close inspection. The anthers are yellow, bilocular, alternate with the dentures of the tube, and attached to its inner surface. The ovary is globular, surmounted by a thick style, which is terminated by a small five-lobed stigma. The fruit is a fleshy berry or drupe, of an ovoid shape, about the size of a cherry, of a yel- lowish color, and containing an elongated bony nut, which is five-celled, each cell containing one seed. History.—This tree is a native of many parts of Asia, but is exten- sively cultivated in the southern parts of Europe and the United States; it does not grow to any great extent north of Virginia, and flowers early in the spring. Its name of Bead-tree, Avas derived from the hard nuts contained in its berries, which are extensively used in Roman Catholic countries for the purpose of making rosaries. The fruit is sweetish, and is reputed powerfully vermifuge ; the pulp of the fruit formed in the middle ages the basis of an ointment for the destruction of lice and other parasitic insects. The recent bark of the root is the part usually employed by practitioners in the south ; it has a nauseous, bitter taste, and an unpleasant, virose smell, and yields its properties to boiling water. A fluid-extract might possibly be prepared from it, for more general use. Properties and Uses.—The bark is anthelmintic, and in large doses, narcotic and emetic. It is said that if gathered at the season when the sap is rising, it will cause narcotic symptoms similar to spigelia. Useful in verminose fevers, and infantile remittents which resemble them, with- out being dependent on the presence of worms. Dose of the powdered bark, twenty grains ; of the decoction, (which is the best form for admin- istration, two ounces of the bark to one pint of water, and boiled down to half a pint,) a tablespoonful every few hours, till the desired effect is produced, to be followed by an active cathartic. An ointment prepared from the pulp of the berry, is said to be employed in Persia, in cases of tinea-capitis, and other obstinate cutaneous affections. The nuts yield an oil by expression, which is said to be anthelmintic, and useful as an application to rheumatic and spasmodic affections, and foul ulcers.

Description.—Balm has a perennial root, which sends up annually several erect, quadrangular stems, usually branched toward the base, and a foot or two in hight. The leaves are opposite, broadly7 ovate or cordate, deeply serrate, pubescent above and smooth beneath, the lower ones on long petioles, the upper nearly sessile. The flowers are white or yellow- ish, upon short peduncles, and in axillary, dimidiate whorls ; bracts few, ovate-lanceolate, petiolate. The calyx is tubular, pentangular, and bila- biate, with the upper lip three-toothed and flattened, the lower cut into two pointed teeth. The corolla is tubular and bilabiate, the upper lip less convex and notched, the lower three-cleft. Stamens ascending. History.—Balm is a native of the south of Europe, but introduced into this country, growing in gardens, and in fields, by the sides of fences, roads, and lanes, flowering in June and July. The whole plant is offi- cinal, and should be collected before the appearance of the flowers. When fresh, its odor very much resembles that of lemons, but when dried, it is nearly inodorous ; its taste is somewhat austere and slightly aromatic, with a faint astringency, and a degree of persistent bitterness. Boiling water extracts its virtues. Balm contains a bitter extractive sub- stance, a little tannin, gum, and a peculiar volatile oil. A pound of the plant yields about four grains of the oil, which is yellowish, or reddish- yellow, very liquid, 975 in density, and possessing the fragrance of the plant in a very high degree. The Nepeta Cilriodora, a powerful emmen- agogue, is sometimes cultivated and employed by mistake for balm. It has the same odor, but may be distinguished by having both surfaces of its leaves hairy7. Properties and Uses. — Balm is moderately stimulant, diaphoretic, and antispasmodic. A warm infusion drank freely, has been service- able as a diaphoretic in febrile diseases, and painful menstruation, and to assist the operation of other diaphoretic medicines ; in combination with ipecacuanha and nitre, it forms a valuable diaphoretic. It is also occa- sionally used to assist menstruation. When given in fevers, it may be rendered more agreeable by the addition of lemon juice. The infusion may be taken ad libitum. Off.

Description.—This plant is also known by the names of Sarsaparilla, Moonseed, Vine-maple, etc. ; it has a perennial, horizontal, woody, very long root, of a beautiful yellow color externally, and a round, striate climbing stem, greenish-yellow when young, and from eight to twelve feet in length. The leaves are roundish, cordate, peltate, three to seven- angled or lobed, smooth, the petiole inserted near the base and from three to five inches long, and white lines radiating from the petiole on the upper surface to each angle, glaucous green above, paler below, entire, and four or five inches in diameter. The flowers are small, yel- low, and disposed in axillary clusters ; sepals four to eight, in a double row ; petals four to seven, minute, refuse, shorter than the sepals. Sta- mens twelve to twenty in the sterile flowers ; anthers four-celled. Pistils two to four in the fertile flowers, raised on a short stalk, one or two ripening into round drupes. Imperfect stamens are sometimes found in the fertile flowers. Drupes about four lines in diameter, black with a bloom resembling frost-grapes, one-seeded. Seeds crescent, compressed. History.—The use of this plant is principally confined to Eclectics, its virtues being unknown to Allopaths. It grows in woods and hedges near streams, from Canada to Carolina and west to the Mississippi, flowering in July. The root is the officinal part, it has a bitter, persistent, but not unpleasant acrid taste, and yields its virtues to water or alcohol. It has not been analyzed. Properties and Uses.—Yellow Parilla is tonic, laxative, alterative and diuretic. In small doses, no obvious effects are produced on the general system ; but in larger doses, a slight increase of the volume of the pulse may be perceived, as well as an increase of the appetite, and the action of the bowels. In excessive doses, purging and vomiting will follow, but no other unpleasant effect. It is a superior laxative bitter. It is much esteemed as a remedy in scrofulous, cutaneous, arthritic, rheuma- tic, syphilitic, and mercurial diseases. Said to be superior to the imported Sarsaparilla. Likewise employed in dyspepsia, general debility, and chronic inflammation of the viscera. Externally, the decoction has been used with good effect as an embrocation in gouty and cutaneous affec- tions. Dose of the decoction, from one to four fluidounces three times a day ; of the extract, from two to six grains three or four times a day; of the saturated tincture, from half a fluidrachm to a fluidrachm. The Franklin Pharmaceutical Institute of the City of New York, advertise the active principle of this root, under the name of Menisperine; it is stated to be a powder of a whitish-brown color, with a not unplea- Mentha Piperita. 631 sant, bitter taste, and is recommended as an alterative, tonic, nervine and laxative. Said to be valuable in the treatment of scrofulous, cutaneous, syphilitic, and mercurial diseases, and superior to sarsaparilla as an alter- ative. Dose from one to three grains, three or four times a day. I have not been made acquainted with the process of manufacture, nor do" I even know whether it is a secret preparation; but I have no doubt, from the known virtues of Yellow Parilla root as an alterative, that if its active principle can be obtained, it will prove a decidedly valuable medicine.

Description.—Peppermint is a perennial, herbaceous plant, with a creeping root, and a quadrangular, channeled, purplish, nearly erect stem, with short recurved hairs, and about two feet in hight. The leaves are opposite, on short petioles, ovate, serrate, acute, smoother on the upper than the under side, of a dark shining green color above and paler beneath; the midrib is furnished with short hairs. The flowers are small, purple, and disposed in short terminal, lax, obtuse spikes, inter- rupted and leafy below. The bracts are subulate, lanceolate, and fringed, the outer ones as long as the calyx. The peduncles are either smooth, or slightly hairy above. The calyx is tubular, slender, furrowed, and covered with pellucid dots, the base quite smooth, five-cleft, with the segments dark-purple, erect, subulate, fringed. The corolla is tubular, longer than the calyx, with its border divided into four segments, of which the uppermost is broadest and notched at its apex. The stamens are subulate, straight; the anthers concealed within the tube of the corolla. The ovary is four-lobed, superior, supporting a slender style longer than the calyx and terminated by a bifid stigma. The seeds are four, lodged in the calyx. History.—Peppermint is a native of England, from whence it has been introduced into this country, where it is largely cultivated for the 6ake of its oil. It also grows wild in wet places. It flowers from July to September. It is said that the roots must be transplanted every three years in order to preserve the fragrance of the plant. The whole herb is officinal, and should be collected when the flowers commence their appearance, and dried in the shade. In the recent state all parts of the plant have a peculiar, powerful, penetrating, diffusive, aromatic odor, and an agreeable, warm, aromatic, pungent, camphorous, bitterish taste, 632 Materia Medica. followed by a singular sensation of coolness when air is admitted into the mouth. Both the odor and taste are retained Avhen the plant is dried, and may be preserved for a long time. Its virtues depend upon a vola- tile oil, which is contained in little vesicles existing throughout the plant, and visible in the leaves ; and which may be obtained by distillation with water. It also contains a portion of tannic acid, as its infusion becomes dark-green with the salts of sesquioxide of iron. Its virtues are taken up in infusion by water, and more readily by alcohol. Properties and Uses.—Peppermint is a powerful, diffusive stimulant, antispasmodic, carminative, and stomachic. Used in the treatment of gastrodynia, flatulent colic, hysteria, spasms or cramps of the stomach, to allay the griping of cathartics, to check nausea and vomiting, and to disguise the unpleasant taste of other medicines. The fresh herb bruised, and applied over the bowels, will often allay sick stomach, and is useful in the cholera of children. The infusion may be drank freely ; but the most usual form of administration is the essence, made by dis- solving one fluidrachm of the oil in one fluidounce of alcohol. Dose, from ten to sixty drops in sweetened water. Off.

MENTHA VIRIDIS. Spearmint. Nat. Ord.—Lamiaceaa. Sex. Syst.—Didynamia Gymnospermia. THE HERB. Description.—Spearmint has a perennial creeping root, from which arises annually several herbaceous, erect, branched, acutely four-angled, smooth, purplish stems from two to three feet in hight. The leaves are of a bright-green color, lanceolate, oblong, acute, ineisely serrate, nearly sessile, opposite, and sometimes a little hairy beneath. The stems and branches are terminated by long spikes of verticillate flowers, the whorls of which are somewhat distant, and furnished with narrow, lanceolate bracts; the pedicels are smooth. The spikes are slender, loose, cylin- drical, interrupted, and attenuated above. The calyx is campanulate, usually smooth, with five equal teeth, and sprinkled, equally with the leaves, with minute dots. The corolla is funnel-shaped, smooth, and of a light-purple color; the stamens are generally shorter than the corolla, with roundish anthers. The ovary is four-lobed, with a filiform style, having a bifid stigma. The seeds are four, small, and often abortive. History.—Spearmint is a native of Europe, but like the preceding species of mint, is extensively cultivated in various moist places in this Menyanthes Trifoliata. 633 country for the sake of its oil, and for domestic use. It flowers in July and Au«ust. The whole plant is officinal, and should be gathered for medical use, just as the flowers appear in dry weather, and carefully dried in the shade. If gathered to obtain their oil, it should be done after the flowers have expanded. It has a peculiar, strong, aromatic odor, and a warm, aromatic, slightly bitter taste, weaker than that of peppermint, but like it leaving a cool sensation in the mouth when air is admitted. These properties are retained for some time by the dried plant. Its virtues are owing to a volatile oil, which may be obtained by dis- tillation with water. Alcohol extracts its virtues, also water by infusion. Properties and Uses.—The carminative, antispasmodic, and stimulant properties of Spearmint are somewhat inferior to those of Pepper- mint; its principal employment is for its diuretic and febrifuge virtues. As a febrifuge, it is superior to peppermint, and may be used freely in warm infusion. The cold infusion is beneficial in high color or scalding of urine, difficult micturition, etc.; it may be used alone, or in combina- tion with marsh-mallow root. A saturated tincture of the fresh herb with gin has been found serviceable in gonorrhea, strangury, sup- pressed urine, gravel, and as a local application to painful hemorrhoids. The oil is diuretic, stimulant, antispasmodic, and rubefacient, and is used externally in rheumatic and other pains. Dose, same as pepper- mint. Off.

MENYANTHES TRIFOLIATA. Buckbean. Nat. Ord.—Gentianaceaa. Sex. Syst.—Pentandria Monogynia. THE LEAVES AND ROOT. Description.—This plant is also known by the names of Bog-bean, Marsh-trefoil, Water-shamrock, etc.; it has a perennial, long, round, horizontal, branching, dark-colored root or rhizoma, about as thick as the finger, and sending out numerous fibers from its under surface; it is regularly intersected by joints about half an inch from each other, and which are formed by the breaking off of the old petioles and their sheaths. The scape is erect, round, smooth, from six to twelve inches high, longer than the leaves, and terminated by a conical raceme of flowers. The leaves are ternate, and stand upon long striated petioles which proceed from the end of the root, and are furnished at their base with sheathinc stipules; the leaflets are obovate, obtuse, entire or bluntly denticulate, very smooth, green on their upper surface, and paler beneath. The flowers are of a pale lilac or flesh color on thick pedicels, with ovate- 634 Materia Medica. concave bracts at base. The calyx is erect, somewhat campanulate, fiA7e-parted, persistent. The corolla is funnel-shaped, with a short tube, deeply cleft into five spreading or recurved, pointed segments, of a white color tipped with rose, smooth externally, and covered on the inner surface with dense, white, shaggy fibers. The stamens are five, shorter than the corolla, and alternate with its segments; anthers red and oblong-sagittate. The ovary is ovate, supporting a slender style longer than the stamens, and terminating in a bifid and compressed stigma. The fruit is an ovate, succulent, two-valved, one-celled capsule, containing numerous minute, roundish seeds. History.—Buckbean is a native of Europe and America, growing in moist boggy soils, or even in ponds and ditches, in temperate or cold climates, and in this country flowering in May. In England it flowers in June and July. The whole plant is medicinal, but the leaves and root only are the officinal parts. The odor of the leaves is faint and disagreeable, and the whole plant has an intensely bitter taste. Water or alcohol takes up its active properties. It contains albumen, chloro- phylle, a peculiar substance precipitable by tannin, but soluble in water, fecula, malic acid, bitter extractive, etc. Its virtues depend on a bitter principle, called menyanthin, which may be obtained sufficiently pure for use by treating the spirituous extract of the plant with hydrated oxide of lead, removing the lead by hydrosulphuric acid, filtering and evaporat- ing the liquor, exhausting the residue with alcohol, and again evaporat- ing with a gentle heat. It has a pure bitter taste, is soluble in water or alcohol, but not in pure ether, and is chemically neuter. Properties and Uses.—Buckbean is tonic and astringent in small doses; in large ones cathartic, and sometimes emetic, especially when fresh. It has been given in dyspepsia, intermittent and remittent fevers with advantage ; and has been highly recommended in chronic rheumatism, hepatalgia, dropsy, worms, and some cutaneous diseases, and as a tonic in scrofula and various cachectic affections. Dose of the powdered leaAres or root as a tonic, from twenty to thirty grains; of an infusion, prepared with half an ounce of the root to a pint of boiling water, from one to two fluidounces; of the extract five or ten grains, to be repeated three or four times a day. As a purgative, sixty grains of the powder, or a gill of the infusion will generally answer, and will occasionally cause vomiting. MITCHELLA REPENS. Partridgeberry. Nat. Ord.—Rubiaceaa. Sex.

Description.—This is an indigenous evergreen herb, with a perennial root, from which arises a smooth and creeping stem, furnished with MOMORDICA ELATERIUM. 635 roundish-ovate, or slightly heart-shaped, petiolate, opposite, flat, coria- ceous, dark-green and shining leaves, usually variegated with whitish .lines. The flowers are white, often tinged with red, very fragrant, in pairs, with their ovaries united. Calyx four-parted. Corolla funnel- form, two on each double ovary, limb four-parted, spreading, densely hairy within. Stamens four, short, inserted on the corolla. Style slender; stigmas four. Fruit a dry berry-like double drupe, crowned with the calyx-teeth of the two flowers, each containing four small and seed-like bony nutlets. Some plants bear flowers with exserted stamens and included styles; others, conversely, those with included stamens and exserted styles. History.—This plant is indigenous to the United States, growing in dry woods, among hemlock-timber, and in swampy places, flowering in June and July. The leaves bear some resemblance to clover, and remain green through the winter. The fruit or berry is bright scarlet, edible, but nearly tasteless, dry and full of stony seeds, and also remains through the winter. The plant is sometimes called Checkerberry, Winter-clover, Deerberry, Squaw-vine, Oneberry, etc. The whole plant is officinal, and imparts its virtues to boiling water or alcohol. It has not been analyzed. Properties and Uses. — Partridge-berry is parturient, diuretic and astringent. Used in dropsy, suppression of urine, and diarrhea, in de- coction. It seems to have an especial affinity7 for the uterus, and is highly beneficial in all uterine diseases. It is said that the squaws drink a decoction of this plant for several weeks previous to their con- finement, for the purpose of rendering parturition safe and easy. It appears to exert a powerful tonic and alterative influence on the uterus. The remedy is peculiarly Eclectic, not being noticed or used by other practitioners. Dose of a strong decoction, from two to four fluidounces, two or three times a day. The berries are a popular remedy for diar- rhea, and dysury. Used as follows, partridge-berry is highly recom- mended as a cure for sore nipples : Take two ounces of the herb, fresh if possible, and make a strong decoction with a pint of water, then strain, and add as much good cream as there is liquid of the decoction. Boil the whole down to the consistence of a soft salve, and when cool, anoint the nipple with it every time the child is removed from the breast. Off.

ELATERIUM. Description.—The Wild or Squirting Cucumber is a perennial plant, with a large fleshy root, from which proceed several thick, round, rough, 636 Materia Medica. trailing stems, divided into many branches, but destitute of tendrils. The leaves are large, rough, irregularly cordate, somewhat lobed, crenate- toothed, hairy, of a grayish-green color above, paler beneath, and sup- ported on long petioles. The flowers are axillary, of a straw-yellow color, and both male and female on the same plant. The males are on short pe- duncles, the female, sessile on the ovary. The calyx five-cleft, with a very short tube. The corolla is composed of five acute segments, tomentose and veined with green. The stamens are short, inserted into the base of the corolla, and support recurved, double-headed, orange-colored anthers; the style is short, cylindrical, three-cleft, and terminated by an oblong stigma. The fruit is watery, of a coriaceous texture, pendulous, oblong, like a small oval cucumber, obtuse at each end, of a greenish or grayish color, about an inch and a half long, an inch thick, and closely set with short bristles. When fully ripe it separates from the peduncle with vio- lence, and expels its juice and seed with considerable force, through an opening at the base, Avhere it was attached to the footstalk, and which is owing to the sudden contraction of the sides of the pepo. History. — The Wild Cucumber is the Ecbalium Elaterium of some botanists ; it is a native of the South of Europe, growing on poor soils, in waste places, and flowering in Jul)7. It has been extensively culti- vated in England for medicinal purposes, where, however, it perishes in the winter ; and being a hardy plant it will grow in most parts of the United States, without much attention. The officinal part of the plant is the juice around the seeds, and which, when properly prepared, forms the elaterium of commerce. It must be collected a little before the period of ripening. When the fruit is sliced and placed upon a sieve, a per- fectly limpid and colorless juice flows out, which after a short time becomes turbid, and in the course of a few hours begins to deposit a sediment. This when collected and carefully dried, is very light and pul- verulent, of a yellowish-white color, slightly tinged with green. It is the genuine elaterium, and was found by Clutterbuck to purge violently in the dose of one-eighth of a grain. But the quantity contained in the fruit is exceedingly small; Clutterbuck obtained only six grains from forty pepos or cucumbers. Commercial elaterium is a much weaker medicine, owing in part, perhaps, to adulteration, but much more to the mode in which it is prepared. In order to increase the product, the juice of the fruit is often expressed with force; and there is reason to believe that it is sometimes evaporated so as to form an extract, instead of being allowed to deposit the active matter. The French elaterium is prepared by expressing the juice, clarifying it by rest and filtration, and then evaporating it to a suitable consistence. As the liquid which remains after the deposition of the sediment is comparatively inert, it will be readily perceived that the preparation of the French Codex must be relatively feeble. The following are the directions of the London Momordica Elaterium. 637 College, with which those of the Dublin College essentially correspond. T" Slice ripe wild cucumbers, express the juice very gently, and pass it ' through a very fine hair sieve; then set it aside for some hours until the thicker part has subsided. Reject the thinner, supernatant part, and dry the thicker part with a gentle heat." As this process is performed at Apothecaries' Hall, the juice after expression, is allowed to stand for about two hours, when the supernatant liquor is poured off, and the matter deposited is carefully dried, constituting the finest elaterium. Another portion of a paler color, is deposited by the decanted liquor. It is incorrectly denominated by the London and Dublin Colleges Extractum Elaterii, as it is neither an extract, strictly speaking, nor an inspissated juice. In the Pharmacopoeias of the United States and Edinburgh, it is named simply Elaterium. As the plant is not cultivated in this country for medicinal purposes, our text-books very properly adopt as officinal, the medicine as it is found in commerce. It is brought chiefly from England ; but probably some of the elaterium prepared in Malta, reaches our market also. As elaterium is insoluble in water, the inquiry has arisen as to what kept it in a state of solution in the juice. Dr. A. T. Thomson suggests that the elaterium does not exist in a formed state in the juice, and is the result of an absorption of oxygen by the fluid, as this is at first nearly colorless and transparent, and does not become turbid or make any deposit until it has been exposed to the action of the air; if the progress of this change be examined by means of a microscope, it will be seen that there is a gradual formation of minute crystals, mingled Avith vegetable matters. The elaterium of the shops, therefore, consists of these crystals, elaterin, mixed with green coloring matter, cellular tissue, starch, etc., and according to the care taken in the preparation, Avill be the proportional quantity of this active principle, as it varies from five to forty-four per cent. Good Elaterium is in light, thin, friable, flat or somewhat curled frag- ments, of a pale, grayish-green color, changing to yellowish by exposure, often bearing the impression of the muslin upon which it Avas dried, having a faint, animal odor, and of an intensely bitter, somewhat acrid taste. It is pulverulent and inflammable, and. so light that it swims upon water. Alcohol is its best solvent. Dr. Paris found it to contain 28 per cent, of starch, 26 extractive matter, 25 ligneous fiber, 5 gluten, a little moisture, and 12 of chlorophylle and elaterin in union. Accord- ing to Mr. Hennel, 100 parts of elaterium contain 44 of elaterin, 17 of chlorophylle, 6 of starch, 27 of lignin, and 6 of saline matters. When elaterium is of inferior quality it is dark-colored, much curled, rather hard, breaking with difficulty or presenting a resinous fracture ; it does not yield over 6 per cent, of elaterin, while the best elaterium yields from 15 to 25 per cent. The Maltese Elaterium is of a pale color, frequently without the slightest tinge of green, in larger pieces, soft, friable, inodorous, sinks in water, and is often mixed with starch or chalk. 638 Materia Medica. Elaterin is the principle in which the active properties of the ding, reside. It may be obtained by thoroughly exhausting elaterium with boiling alcohol, concentrating the tincture to the consistence of thin oil, or so long as no separation takes place, and then pouring it while hot into a weak boiling solution of potassa. The potassa retains the chloro- phylle or green resin in solution, and the elaterin crystallizes as the liquor cools. When pure, elaterin is in very7 delicate, colorless crys- tals, which are striated sattiny prisms, with a rhombic base. It is per- manent in the air, inodorous, but of an extremely bitter and somewhat acrid taste, insoluble in water and alkaline solutions, soluble in alcohol, and hot olive oil, and slightly soluble in ether, diluted acids, and fixed oils. It fuses at a temperature between 300° and 400°, and at a higher temperature it is decomposed, with the evolution of thick, white, acrid vapors, having an ammoniacal odor. It is a neutral body containing no azote, but having the constitution C20 Hi4 Os. Elaterium is seldom adulterated ; its variableness of strength depends probably7 more upon its mode of preparation, or the time of its collection. It should be light, pale grayish-green, and friable, not brown or com- pact, should not effervesce with acids, and should yield from 15 to 25 per cent, of elaterin on analysis. Properties and Uses.—Elaterium is a powerful hydragogue cathartic, operating with great violence in doses of a few grains, causing diffuse inflammation of the stomach and bowels, characterized by vomiting, griping pain, and profuse diarrhea. In ordinary medicinal doses it pro- duces copious watery evacuations, attended with considerable depression of the circulation and nervous system, and most generally nausea and vomiting. Hence, it is often used in dropsy, to aid in removing the effused fluid, as a revulsive in cerebral affections, and whereArer a hydra- gogue or revellent effect is indicated. It also increases the flow of urine. The dose of the common commercial article is from a quarter to half a grain, administered every hour or tAvo until it operates; of Clutterbuck's elaterium, which is the best, and is so named because it is prepared after the process recommended by Clutterbuck, from one-eighth of a grain to one-tenth, every three or four hours; of elaterin, from one-six- teenth of a grain to one-twelfth, and is best given in solution. An excellent purgative solution is made with one grain of elaterin, a fluid- ounce of alcohol, and four drops of nitric acid; of which from thirty to forty drops may be given diluted with water. Off.

Description. — Horsemint is an indigenous perennial or biennial plan. with a fibrous root, and a stem two or three feet high, herbaceous, obtusely four-angled, whitish, downy, and branching. The leaves are oblong-lanceolate, remotely-serrate, smooth, punctate, tapering to a short petiole. The flowers are yellow, spotted with red or brown, and disposed in numerous dense, axillary whorls, having lanceolate, yellow- ish and purple, sessile bracts, obtuse at the base, and longer than the whorls. Calyx tubular, downy; calyx-teeth unequal, short and rigid, awnless. Corolla, nearly smooth, yellow with brown spots, the upper lip villous at the apex, somewhat vaulted, and spotted with purple; the tube scarcely exceeding the calyx. Stamens two, not exceeding the upper lip of the corolla. History.—This plant is found growing in light and sandy soils from New Jersey to Florida, and in the Western States to Louisiana, flower- ing from June to September. The whole plant has an aromatic odor and a warm, pungent, somewhat bitter taste, and abounds in a powerful volatile oil on which its active virtues depend. The oil may be obtained from the fresh herb by distillation with water. The plant yields its virtues to alcohol or infused in boiling water. Properties and Uses.—Horsemint is stimulant, carminative, sudorific, diuretic and anti-emetic. The infusion or essence used in flatulence, nausea, vomiting, and as a diuretic in suppression of the urine, and other urinary disorders. The warm infusion is a stimulating diaphoretic, and has acquired some reputation as an emmenagogue; it maybe drank freely. The M. Didyma and M. Squarrosa may be used as substitutes for the above.

Description.—This plant, also known by the names of Ova-ova, Bird's Nest, Indian-pipe, Fit-plant, etc., has a dark-colored, fibrous, perennial root, matted in masses about as large as a chestnut-burr, from which arise one or more short, ivory-white stems, from four to eight inches high, furnished with sessile, lanceolate, white, semi-transparent, approxi- 640 Materia Medica. mate leaves or bracts, and bearing a large, white, terminal, solitary flower, which is at first nodding, but becomes upright in fruit. The calyx is represented by from two to four scale-like deciduous bracts, the loAver rather distant from the corolla. The corolla is permanent, and composed of five distinct, erect, fleshy petals, which are narrowed below and have a small nectariferous pit at the base. Stamens ten, sometimes eight; anthers short on the thickened apex of the hairy filament, two- celled, opening by transverse chinks. Stigma five-crenate, depressed, beardless. Pod or capsule five-celled, five-valved; seeds numerous, invested with an arillus-like membrane. History.—This is a singular plant, found in various parts of the Union from Maine to Carolina, and westward to Missouri, growing in shadv, solitary woods, in rich moist soil, or soil composed of decayed wood and leaves, and near the base of trees, on whose roots it is said to be para- sitic. The whole plant is ivory-white in all its parts, resembling frozen jelly, and is very succulent and tender, so much so that when handled it dissolves and melts aAva}7 in the hands like ice. The flowers are ino- dorous, and appear from June until September; their resemblance to a pipe has given rise to the names Indian Pipe, or Pipe-plant. The root is the part used; it should be gathered in September and October, care- fully dried, pulverized, and kept in well-stopped bottles. Properties and Uses. — Iceplant-root is tonic, sedative, nervine, and antispasmodic. It has also been employed in febrile diseases, as a sedative, and diaphoretic. The powder has been employed in instances of restlessness, pains, nervous irritability, etc., as a substitute for opium, without any deleterious influences. It is reputed to have cured remit- tent and intermittent fevers, and to be an excellent antiperiodic. In convulsions of children, epilepsy, chorea, and other spasmodic affections, its administration has been followed with prompt success; hence its com- mon name, Fit or Convulsion-root. The juice of the plant, alone or combined with rose-water, has been found an excellent local application to obstinate ophthalmic inflammations, to ulcers, and as an injection in gonorrhea, inflammation and ulceration of the bladder. Dose of the powdered root, from half a drachm to a drachm, two or three times a day. This plant is undoubtedly one of great value, and deserving of more confidence and attention than is at present bestowed upon it. It is not the Mesembryanthemum Crystallinum or Iceplant of Europe, which has a creeping stem a foot or more in length, Avith large, ovate, wavy, frosted leaves, and white flowers; and the whole plant is covered over with frost-like, warty protuberances, which give a very singular aspect to it. Morus Rubra. 641 MORUS RUBRA. Red Mulberry. Nat. Ord.—Urticaceaa; Suborder, Moreaa. Sex. Syst.—Moncecia Tetrandria. THE fruit. Description.—Morus Rubra, or the Red Mulberry, is but a shrub in the northern and New England States, from fifteen to twenty feet high, but in the Middle and Western States it attains an elevation of from fifty to sixty feet, with a diameter of two feet, and covered with a gray- ish, furrowed, much broken bark. The leaves are alternate, rounded or subcordate at base, acuminate, equally serrate, either ovate or three- lobed, rough above and pubescent beneath, thick, dark-green, from four to six inches long, and about two-thirds as wide. The flowers are small, monoecious, rarely dioecious; the sterile ones in loose spikes ; calyx four- parted ; the fertile ones in dense spikes; calyx four-parted; styles two, filiform, stigmatic down the inside. Ovary two-celled, one of the cells smaller and disappearing. Achenium ovate, compressed, inclosed within the succulent, berry-like calyx. Fertile spikes cylindric, constituting a dark-red, thickened, oblong and juicy, compound berry or fruit. The sterile spikes are rather slender. History. — The red mulberry is indigenous to the United States, growing in rich woods, flowering in May, and ripening its fruit in July. The wood of the tree is fine-grained, strong, and durable. The fruit is oblong-oval, of a dark-red color, almost black, and consists of minute berries united together and attached to a common receptacle, each con- taining a single seed, the succulent envelope of which is formed by the calyx. It somewhat resembles a blackberry, is inodorous, but with a sweet, mucilaginous, acidulous taste, and is very juicy. They are said to consist of bitartrate of potassa, pectine, sugar, lignin, coloring matter and water. Properties and Uses.—Mulberries possess very slightly nutritive qual- ities ; they are refrigerant and laxative, and their juice forms a pleasant and grateful drink for patients suffering under febrile diseases, as it checks thirst, relieves febrile heat, and when taken freely, gently relax the bowels. A syrup made from the juice, and added to water, answers the same purpose, and forms a pleasant addition to gargles in quinsy. If the berries are eaten to excess they are apt to induce diarrhea. The bark of the tree is said to be cathartic and anthelmintic, having expelled tapeworm. The Morus Nigra of Europe possesses similar properties. The Morus Alba, a native of China, with white fruit Avhich is SAveeter and less grateful than the others, is the kind cultivated as a source of food for the silk-worm. 41 642 Materia Medica. MOSCHUS. Musk. History.—This article is obtained from the Moschus Moschiferus, a wild ruminating animal, rather larger than the domestic goat, and approaching the deer in its characters, and which is an inhabitant of Central Asia. At the posterior part of its abdomen, there is a small sack situated immediately under the skin, which opens a little in front of the preputial orifice, and which is filled with a thick fluid, abounding particularly in the rutting season. This fluid, in the dried state, is musk. It is removed from the animal in its containing bag, and dried in this state for exportation. The musk-bag, or pod is usually plano-convex ; and in general the plain surface is a bare membrane, while the convex surface is covered with stiff hairs ; but sometimes the hairy and mem- branous parts are reversed. It weighs, along with its contents, between five and nearly ten drachms, and contains on an average two drachms and two-thirds of musk. Musk is in the form of irregular, reddish black, rather unctuous grains, possessing an overpowering, most pene- trating, diffusive odor, and a bitterish, corresponding taste. Rectified spirit is its best solvent. Musk is now scarcely ever prescribed, both on account of its high price, and the extreme difficulty of obtaining a pure article ; as nearly all the musk of the shops, at the present day, is an artificial or factitious article. Camphor, cinnamon, almond syrup, wax, etc., when mixed with musk, destroy its odor. Musk is inflammable, burning with a white flame, and leaving a light- spongy charcoal. In some individuals its odor produces headache and other disagreeable symptoms, and has even given rise to convulsions. It consists of a great number of proximate principles, as stearin, elain, cholesterin, a peculiar fixed acid, resin, osmazome, numerous salts, and free ammonia combined with an odoriferous principle, and which has not yet been separately detached. Ether is said to be a good solvent; and the emulsion or syrup of bitter almonds, or cherry laurel-water, very much diminishes its odor. From its high price, musk is very liable to adulterations; indeed it is very rare that the pure article can be had at the shops in this country. These adulterations are very difficult to detect. Musk Avhich burns with difficulty7, which has a feeble odor, and a color either pale or entirely black, which feels gritty to the finger, is very moist, or contains obvious impurities, should be rejected. Properties and Uses.—Musk is stimulant and antispasmodic ; it in- creases the vigor of the circulation, and exalts the nervous energy, without causing any great derangement of the purely cerebral functions. It is asserted to have been used with much advantage in the following diseases: in all spasmodic affections, typhus, and low forms of fever, obstinate hiccough, pertussis, convulsions of infants, epilepsy, hysteria, Mucuna Pruriens. 643 asthma, palpitation of the heart, chorea, colic, etc. Fifteen grains of musk combined with extract of valerian, and hydro-alcoholic extract of cimicifuga, of each, fifteen grains, and divided into fifteen pills, will be found beneficial in pneumonia accompanied by delirium, and in the involuntary movements observed in low typhoid fevers. One pill may be given every hour or two, until there is a marked improvement in the symptoms. In small doses musk is hypnotic. If its use is long con- tinued it imparts its peculiar odor to the secretions. It should always be given in substance, either in the form of pill or emulsion. Dose from five to twenty grains, every two or three hours. Nitre, cochineal of each two grains, musk one grain, mix and form a powder. This powder given and repeated every two or three hours is said to be very useful in some low forms of fever, and in febrile or inflammatory affec- tions with spasmodic action or delirium. An artificial musk is prepared, by carefully adding, drop by drop, three parts of fuming nitric acid to one of unrectified oil of amber. The acid is decomposed, and the oil converted into an acid resin, which must be kneaded under pure water, until all excess of acid is removed. The substance which remains is of a yellowish-brown color, viscid, and an odor similar to musk, for which it may be used as a substitute in doses of from fifteen to thirty grains. MUCUNA PRURIENS. Cowhage. Nat. Ord.—Fabaceaa. Sex. Syst.—Diadelphia Decandria. THE BRISTLES OF THE PODS. Description.—This plant has a perennial and fibrous root, from which arises a herbaceous, climbing, cylindrical, tomentose stem, divided into many branches, and which rises to a considerable hight, twining round the trees in its vicinity. The leaves are alternate, on long petioles, about a foot from each other, and pinnately-trifoliate; the central leaflet is rhomboidal; the two lateral ones, oblique at the base, dilated exter- nally ; all of them are entire, ovate, acuminate, smooth on the upper surface, and hairy beneath. The flowers are large, inodorous, of a purplish or violet color, somewhat resembling those of the pea in form, and are usually collected by threes in long, pendulous, axillary racemes. The calyx is hairy, pink, campanulate, bilabiate, the lower lip trifid, and the upper entire, semi-ovate. The corolla consists of a vexillum, which is roundish, concave, and double the length of the calyx, but shorter than the other petals. The carina is straight, obtuse, and furnished on each side of the apex with a short spur. The alae are oblong, and as long as the carina. The stamens are ten, diadelphous, five of them sup- porting oblong, linear anthers, and the others ovate, hirsute ones. The ovary is oblong, villous, and furnished with a slender style, with a small 644 Materia Medica. orbicular stigma. The legume is a coriaceous pod about three or four inches long, the thickness of the finger, compressed, curved like the letter S, thickly set with short, reddish-brown, brittle, stinging hairs, somewhat terete and keeled ; when handled or rubbed on the skin, they produce an intense itching sensation. The seeds are oval-oblong, brown or variegated, with a white hilum. History.—This plant is a native of the West Indies, and other tropical parts of South America ; it is found in woods, along river courses, upon fences, and in waste, neglected places. The East Indian species, Mucuna Prurita, is entirely distinct from the one under consideration. The offi- cinal part of the plant is the hair of the pods, which are generally imported into this country attached to pod, and from which they are carefully removed, so that they do not fasten to the operator's hands. Properties and Uses.—Cowhage is a mechanical anthelmintic, acting by penetrating the body of the worms; its decoction or tincture has no anthelmintic properties. It is used in the treatment of intestinal worms, which are expelled alive. It has no effect on tenia, but appears more serviceable in removing the lumbrici and ascarides. Dose, from one drachm to half an ounce in syrup or molasses, and followed, a few hours afterward, by a purgative. The application of oil is the best to allay the heat and itching it produces when rubbed on the skin. Cowhage has been recommended in the form of an ointment, as a cutaneous irritant, in the place of croton oil, and tartar-emetic, also as a good medium for the endermic application of various substances, as muriate of morphia. The proportions are, seven grains and a half of the hairs of cowhage to an ounce of lard. This must be rubbed in from ten to twenty minutes; seven or eight grains are usually sufficient. The immediate effect is the production of a sensation resembling stinging with nettles ; but the burn- ing sensation and the itching diminish during the friction, and entirely pass off in less than half an hour. The skin generally becomes covered with white flat papula, which soon disappear, leaving a sensation of heat. It produces no inconvenience, and children bear it easily. MYRICA CERIFERA. Bayberry. Nat. Ord.—Myricaceaa. Sex. Syst.—Dioacia Tetrandria. THE BARK AND WAX. BAYBERRY WAX. Description.—This plant, known also by the names of Wax Myrtle, Wax-berry, etc., is a branching, half-evergreen shrub from one to twelve feet in hight, and covered with a grayish bark. The leaves are glabrous, cuneate-lanceolate, rather acute or obtuse, distinctly petiolate, margin entire, but more frequently remotely dentate, particularly toward the Myrica Cerifera. 645 end, paler and with distinct veinlets beneath, generally twisted or revo- lute in their mode of growth, shining and resinous, dotted on both sides, and from an inch and a half to two and a half inches in length, by half an inch to three-quarters wide. The flowers appear in May before the leaves are fully expanded. The males grow in aments, which are ses- sile, erect, from six to nine lines in length ; originating from the sides of the last year's twigs. Every flower is formed by a concave rhom- boidal scale, containing three or four pairs of roundish anthers on a branched footstalk. The females, which are on a different shrub, are less than half the size of the males, and consist of narrower scales, with each an ovate ovary, and two filiform styles. To these aments succeed clusters or aggregations of small globular fruits resembling berries, which are at first green, but finally become nearly white. They consist of a hard stone inclosing a dicotyledonous kernel. The stone is studded on its outside with small black grains resembling fine gunpowder, over which is a crust of dry greenish-white wax, fitted to the grains and giving the surface of the fruit a granulated appearance. The fruit is persistent for two or three years. History.—This plant is found in damp places in many parts of the United States, and is very abundant in New Jersey. The bark of the root is the officinal part; boiling water extracts its astringent principles, and alcohol its stimulating. It probably contains tannin, gallic acid, extractive matter, and lignin. The root should be collected late in the fall, cleansed from dirt and foreign substances, and then while fresh, pounded with a hammer or club to separate the bark, which should be thoroughly dried without exposure to a wet or moist atmosphere, then pulverized, and kept in darkened and well-closed vessels. The berries of this plant are studded over with small, black granulations, and covered by a white, mealy crust, consisting of a kind of wax, which is separated by placing the berries in boiling water, when it will melt and collect on the surface of the fluid, and on becoming cool, congeals into a concrete substance. Bayberry or Myrtle Wax, as it is sometimes called, is of a pale, grayish-green color, somewhat diaphanous, more brittle, and at the same time more unctuous to the touch than beeswax, of a feeble odor, and a slightly bitterish taste. It is insoluble in water, scarcely soluble in cold alcohol, soluble in boiling alcohol, but not permanently so in boiling ether, and slightly so in oil of turpentine. One hundred parts of wax contain eighty-seven parts of cerin, and thirteen of myricin. The wax boiled with ether, may be obtained colorless as the liquid cools, while the ether holds the green substance in solution. A bushel of bay- berries will yield about four pounds of wax. Properties and Uses.—Bayberry Bark is astringent and stimulant, and in drachm doses, it is apt to occasion emesis. The bark has been suc- cessfully employed in scrofula, jaundice, diarrhea, dysentery, and other 646 Materia Medica. diseases where astringent-stimulants were indicated. The powdered bark, combined with bloodroot, forms an excellent application to indolent ulcers, and has likewise been employed as a snuff for the cure of some forms of nasal polypus. In the form of poultice, with elm, or alone, it is a valuable application to scrofulous tumors or ulcers. The decoction is beneficial as a gargle in sore mouth and throat, and is of service in injection, in leucorrhea and fistula, and also as a wash for ulcers, tinea- capitis, etc. It also forms an excellent gum wash, for tender, spongy, and bleeding gums. The leaves are reputed antispasmodic, antiscor- butic and astringent. Probably the M. Pennsylvania, M. Carolinensis, and M. Gale, possess similar properties. The Bayberry Wax is astrin- gent and slightly narcotic, and has been successfully employed in epi- demic typhoid dysentery. It is also used in the form of plaster, as an application to scrofulous and other ulcers. Dose of the powdered bark, from twenty to thirty grains; of the wax, one drachm ; of the decoction of the leaves or bark, from two to four fluidounces. Off.

Myricin. dried alcoholic extract of bayberry bark. Preparation.—I am indebted to Drs. Hill & Co., of this city, for a description of the mode of preparing this article. Make a saturated tincture of Bayberry Bark, filter, distil off a portion of the alcohol, evaporate the remainder by means of a water-bath until the mass is of a syrupy or semifluid consistence, then spread it in thin layers on glass or metallic plates, and allow it to dry by spontaneous evaporation, which will require several weeks. Some manufacturers precipitate the myricin from the tincture, by water, similar to the method employed for obtaining podophyllin; the article obtained by this process is lighter colored than that had by the above, and the yield is much less, beside a great portion of the astrin- gency of the myricin is taken up by the water, and the agent possesses merely stimulant, with but slight astringent virtues. History.—The profession are indebted to Messrs. F. D. Hill & Co., of this city, for first preparing and introducing this elegant article to their notice. It forms a light grayish-brown powder, with a peculiar, spicy smell, and a peculiar, bitterish-astringent taste, with some degree of per- sistent pungency. It is soluble in alcohol, partially soluble in ether, and its astringency is taken up by water, the rest being insoluble. Sulphate of iron forms a black inky liquid with the water in which Myristica Moschata. 647 myricin has been agitated. It is perfectly soluble in water to which ammonia has been added. Properties and Uses.—Myricin is a stimulant and astringent, and will be found a very advantageous remedy in chronic diarrhea and dysentery, in dysentery with typhoid symptoms, and in colliquative diarrhea of phthisis ; in scarlatina it may be given with advantage, while a decoc- tion of the bark is employed as a gargle ; it will likewise be found a useful remedy for aphthous affections, when given internally, and applied locally. It forms an efficacious application to tender, spongy, bleeding gums, and an excellent snuff for polypus, also for headache and catarrhal affections. It is likewise beneficial in jaundice, and in combi- nation with leptandrin and apocynin, I have successfully treated several cases of this affection. In some instances of cholera, it will be service- able, given in combination with geraniin. Combined with leptandrin, podophyllin, or some other cathartic, it may be employed with benefit in the latter stages of typhoid fever. Dose, from two to ten grains of the powder, which may be repeated as often as required. MYRISTICA MOSCHATA. Nutmeg. Nat. Ord.—Myristicaceaa. Sex. Syst.—Dioacia Monadelphia. THE KERNELS OF THE FRUIT. Description.—This is a tree from twenty to twenty-five feet high, having a grayish-brown and somewhat smooth bark, abounding in a yellow juice, and furnished with many whorls of spreading branches. The leaves, which are alternate and on petioles from half to three-fourths of an inch long, plane above, are oblong, approaching to elliptical, sub- bifarious, glabrous, rather obtuse at the base, acuminate, quite entire, aromatic, dark-green and somewhat glossy above, paler beneath, with simple parallel veins, and from three to six inches long. The flowers are male and female upon different trees, minute, and pale yellowish ; the males are disposed in axillary, solitary clusters, from three to five on a peduncle. The calyx is urceolate and petaloid, thick and of a fleshy texture, indistinctly reddish-pubescent, dingy pale-yellow, and divided into three erect teeth. The stamens are united into a thickened, whitish, cylindrical column, about as long as the calyx, the upper half bearing from six to ten connate, linear-oblong, two-celled anthers, free at their base, and opening longitudinally. The peduncles and pedicels are glabrous, the latter having a quickly deciduous, ovate bract at its summit, often pressed close to the flower. The female flowers are scarcely different from the male, except that the pedicel is frequently solitary. Pistil solitary, shorter than the calyx, broadly ovate, a little tapering upward into a short style, and terminating in a two-lobed 648 Materia Medica. persistent stigma. The fruit is pyriform, pendent, having a fleshy pericarp opening by two, nearly equal, longitudinal valves, yelloAvish, almost white within, four or five lines thick, and abounding in an astringent juice. The arillus (mace), is thick, between horny and fleshy, much laciniated, folded and anastomosing toward the extremity, almost enveloping the nut, and so tightly as to form inequalities on its surface; when fresh, it is brilliant scarlet; when dry, much more horny, of a yellow-brown color, and very brittle. The nut is oval or broadly ovate, with a hard, rugged, dark-brown, shining shell, marked by the mace, pale and smooth within, and about half a line thick; it closely envelops the seed, and its inner coat dips down into the substance of its albumen, giving it a marbled appearance. The seed or nutmeg is oval, pale-brown, quite smooth when fresh, but soon becomes shriveled, with irregular, vertical lines or furrows on its surface. Its substance or albumen is firm, fleshy, and whitish, being traversed by veins of a red-brown color, abounding in oil. Near the base of the albumen, and imbedded in a cavity in its substance, is the embryo, which is small, fleshy, yellowish- white, rounded below, and where is found the hemispherical radicle ; its cotyledons of two, large, somewhat foliaceous, plicate lobes, in the center of which is seen the plumule. History.—The nutmeg tree is a native of the Molucca Isles, and is cultivated in Sumatra, French Guiana, the Mauritius, and various West Indian islands. The tree is produced from the seed, and does not flower until the eighth or ninth year, when it continues to bear fruit and flowers together, for sixty or seventy years. Its cultivation is said to require but little trouble. In the East Indies three crops are gathered annually. The fruit is gathered by hand and is never used whole, on account of its acridity; the outer pulpy coat is removed with a knife, and thrown away, the arillus is then carefully separated, flattened, and dried in the sun, sprinkled with sea-water, and again partially dried; in this pro- cess it changes from its original crimson color to a brownish-yellow, and constitutes the mace of commerce. The nuts require more attention, as they are liable to be attacked by insects; they are first exposed to the sun for a few days, and then slowly dried by a slow fire for a length of time, until the seed becomes perfectly detached from the shell; this is then broken and the seeds steeped in a mixture of lime and water, to protect them from insects and prevent the volatilization of their aroma, and thus prepared they constitute the nutmegs of commerce. The kernel of the fruit, or nutmeg, and the arillus of the nut, or mace, are the officinal parts. Nutmegs reach this country from the East Indies, from Europe, and a small portion from the West Indies. The finer kinds of nutmeg are small, short, of an olive shape, firm, heavy, externally marked with reticulated furrows, and lightish brown or white, from having been dipped for preservation in milk of lime; internally grayish-red, and beautifully marbled with darker brownish- Myristica Moschata. 649 red veins, from which oil may be easily expressed with the point of a warm knife. They have a strong, peculiar, delightfully fragrant odor, and a powerful, bitter, warm aromatic taste. Their virtues are extracted by alcohol or ether. According to Bonastre, they contain 54 per cent. of lignin, 24 of stearin, 7.6 of elain, 6.0 of volatile oil, 2.4 of starch, 1 of gum, and 0.8 of an acid substance. By distillation with water, the volatile oil may be obtained. The small, round heavy nutmeg is esteemed superior to those which are larger, longer, lighter, less mar- bled, and not so oleaginous. It makes a grayish-brown, somewhat fatty powder. All inferior nutmegs may be recognized by the above description. The powder of nutmegs beaten to a pulp with a little water, and pressed between heated plates, yields from ten to thirty per cent, of a fragrant, orange-colored, concrete oil, commonly, but incorrectly called Oil of Mace. It is the Myristicce Adeps of the Edinburgh Pharmaco- poeia, and the Myristicce Oleum of the London. The best quality of this oil is imported from the East Indies in stone jars ; it is in rectangu- lar cakes, enveloped in the leaves of some plant. It has the consistence of suet, and possesses the odor and taste of the nutmeg. It is soluble in four parts of boiling alcohol, which deposits the solid part of the oil, myristicin, in silky crystals. The crude fat likewise contains a soft, yellowish or brownish oily substance, soluble in cold alcohol or ether, and a volatile oil. Myristicin is insoluble in cold alcohol or ether, melts at 88°, and is a compound of Myristicic acid and glycerin. An inferior concrete oil is prepared in Holland from spoiled nutmegs. An artificial preparation is made by mixing together various proportions of suet, palm oil, wax, spermaceti, etc., coloring the mixture, and flavoring it with the volatile oil of nutmeg. Mace is in the shape of a flat membrane irregularly slit, smooth, soft, flexible, of a reddish or orange-yellow color, and an odor and taste closely resembling those of nutmeg. It is seldom used in medicine. It contains a small quantity of volatile oil, a fixed, odorous, yellow oil, soluble in ether, insoluble in boiling alcohol; a fixed, odorous, red oil, soluble in every proportion in alcohol or ether; a peculiar gummy matter, analogous to gum and amidin, constituting one-third of the whole, and a small proportion of ligneous fiber. On distillation, mace affords a vola- tile oil, and by pressure a fixed oil, less concrete than that of nutmegs. Inferior mace may be knovra by its brittleness, by its being whitish or pale-yellow, and having but little taste and odor. Properties and Uses. — Both nutmeg and mace possess aromatic stimulating properties, and are occasionally used to remove flatulency, correct the nausea arising from other drugs and to allay nausea and vomiting. The nutmeg forms a very agreeable addition to various drinks for convalescents, as well as to some articles of diet; it is gener- ally grated over them, or mixed with them. Applied locally, grated 650 Materia Medica. nutmeg mixed with lard has been found an excellent application in piles— and the nutmeg roasted is used in some parts of the country internally, as a domestic remedy for leucorrhea. I have known the following pre- paration to cure several cases of intermittent fever, and have been assured of its almost universal success in this disease. It is also recom- mended for the cure of other forms of fever. Char a nutmeg by hold- ing it in the flame, and permitting it to burn by itself without disturb- ance; when charred, pulverize it, combine it with an equal quantity of burnt alum, and divide the mixture into three powders. On the com- mencement of the chill give a powder—if this does not break it, give the second powder on the approach of the next chill, and if not cured, the third powder must be given as the succeeding chill comes on. Usually the first powder effects a cure, and it is seldom that the three powders are re- quired. The bowels should always be acted upon by a purgative previous to their administration. It is certainly deserving attention, though I do not pretend to account for its action. Dose of nutmeg or mace, from five to twenty grains. Larger doses possess narcotic qualities, and in doses of two or three drachms, stupor and delirium have been produced. . Off. Prep. —Tinctura Lavandula Composita. MYROSPERMUM PERUIFERUM.

Description.—This is the Myroxylon Peruiferum of Linnaus ; it is a large tree, having the trunk and branches covered with a gray, coarse, thick, compact bark, of a pale color internally, and filled with a fragrant resin. The branches are almost horizontal. The leaves are alternate, and composed of two to five pairs of nearly opposite leaflets, which are ovate-lanceolate, acute, coriaceous, somewhat obtuse and emarginate at the apex, smooth, shining above, hairy beneath, entire, with pellucid dots, and on short petioles ; many leaves terminate unequally. The flowers spring from the axils of the leaves in long, tomentose, erect racemes, longer than the leaves, with slender peduncles and a small bract at the base of each. The calyx is campanulate, dark-green, nearly equally five-toothed, with the odd tooth remote from the others. The corolla is formed of five white petals, the upper one reflexed, broad, roundish, emarginate, and twice the size of the others; the remaining four distinct, linear-lanceolate, reflexed, spreading. Stamens ten, dis- tinct, spreading, shorter than the petals, with elongate, sulcate, mucro- nate anthers. The ovary is oblong, pedicellate, with a short, subulate, crooked style, bearing a simple stigma. The fruit is a pendulous, Myrospermum Peruiferum. 651 yellowish legume, somewhat clavate and curved, and terminating by the persistent curved style. It contains a single seed, which is crescent- shaped and enveloped in a yellow liquid balsam, which hardens into resin. History.—Although the above is generally considered to be the tree which yields Balsam of Peru, yet there has been much uncertainty as to the particular species, and even at the present time the question is not satisfactorily determined. It is probable that the balsam is obtained from more than one species of Myrospermum, as it presents varieties in commerce, that seem to show a difference of origin. The above tree is a native of several parts of South America, and grows in low, warm, sunny situations, especially amidst the Peruvian forests on the banks of the Maranon, flowering from August to October. By the natives it is called Quinquino. The tree abounds in a balsamic juice, which flows copiously on an incision being made in the bark, and is collected on rags which are placed in the incisions, and replaced by others, as they be- come saturated. The rags are then boiled in water, from the top of which the balsam is skimmed off, as it rises, and put into vessels for purification and exportation. It usually comes to this country in tin canisters, with a whitish scum upon its surface, and a deposit which is dissolved by heat. Balsam of Peru is opake, of a dark reddish-brown color, syrupy, or of the consistence of molasses, of an agreeable balsamic odor, and an acrid, aromatic, bitterish taste, leaving a prickling sensation in the throat when swallowed. Its specific gravity is about 1.155. On exposure to the air it does not dry up; it burns when exposed to flame, with a white smoke, and diffusing a fragrant odor. It is soluble in a large pro- portion of alcohol, but only partially in ether; it is miscible with water by means of mucilage. Boiling water removes from it a crystalline acid, supposed by Stolze to be benzoic acid, and by Fremy, cinnamic. Various analyses have been made but none of them are satisfactory. Supposed to contain an oily substance, called Cinnameine, resinous mat- ter, benzoic acid, extractive, moisture, etc. There is likewise a variety of Peruvian balsam, of a pale-yellowish color, syrupy, highly fragrant, and of a bitterish, acrid, somewhat aromatic taste. It is called White Peruvian Balsam, and is said to be procured from the fruit, by expression. When dried, it constitutes the Dry Peruvian Balsam, or Indian Opobalsamum, and is of a reddish, pulver- izable, resinoid character. Balsamito, is the name of a tincture of the fruit of the tree in rum, and is said to possess stimulant, diuretic, and anthelmintic properties. The natives of Central America employ it as a wash to remove freckles, and as a local application to indolent or gan- grenous ulcers. Neither of these varieties reach the markets of this country. 652 Materia Medica. Properties and Uses. — Balsam of Peru is a stimulating tonic and expectorant, acting more especially on mucous tissues. It has been recommended in chronic catarrh, asthma, pulmonary complaints gene- rally, mucous inflammation of the stomach and bowels, gonorrhea, leu- corrhea, gleet, and chronic diarrhea. Externally, it forms an excellent application to indolent ulcers, wounds, ringworm of the scalp, and other cutaneous affections. It may be applied alone, or in ointment made by melting it with an equal part by weight of tallow. The dose is from ten to thirty drops, and is best given diffused in water by means of sugar and the yelk of egg, or gum arabic. MYROSPERMUM TOLUIFERUM. Balsam of Tolu. Nat. Ord.—Leguminosaa. Sex. Syst.—Decandria Monogynia, THE JUICE OF MYROSPERMUM TOLUIFERUM. Description. — There has been no detailed description given of this tree. It is supposed to resemble the M. Peruiferum, differing in its leaflets, which, according to Richard, are thin, membranous, obovate, with a lengthened and pointed apex, and the terminal ones being larger than the others. History. — As with the preceding article, so with the present, it is involved in considerable obscurity ; it being uncertain whether the same trees which yield Balsam of Peru, furnish likewise that of Tolu. Some consider that the two balsams are derived from the same species, and that they differ merely on account of their mode of collection and preparation. The M. Toluiferum, which is undoubtedly one species from which Tolu is obtained, is found in several parts of South America, especially on the elevated plains and mountains near Carthagena, Tolu, and in the Magdalena province of Colombia. The balsam is said to be procured by making incisions into the trunk of the tree, and as it exudes, it is received into vessels of various kinds, in which it concretes. It is brought from Carthagena, contained in calabashes, earthen jars or glass vessels. When first imported, it is usually soft and tenacious, but by age becomes hard and brittle, resembling resin. It is shining, translu- cent, of a pale yellowish-red or brown color, very fragrant, and a warm, sweetish, pungent, rather agreeable taste. It softens when chewed, and exposed to heat, melts readily; when inflamed it evolves an agree- able odor. It is wholly soluble in alcohol, ether and the volatile oils, and like Balsam of Peru, gives up its acid to boiling water. By distil- lation with water a small quantity of volatile oil is obtained, and if the heat be continued, its acid sublimes. When dissolved in the smallest quantity of a solution of potassa, it is said to lose its characteristic odor, Myrtus Pimenta. 653 and acquire that of the clove-pink. Its chemical composition has not been satisfactorily ascertained, but appears to be similar to that of the Balsam of Peru, differing only in its greater tendency to become resin- ous. The pure volatile oil, called Tolene, is a hydro-carbon (Cio Hs). Guibourt observes that as the balsam solidifies, it becomes less odorous, and holds more acid; and thinks that the acid is increased at the ex- pense of the oil. Properties and Uses.—Balsam of Tolu, like that of Peru, is a stimu- lant tonic and expectorant, and may be used as a substitute for it, in chronic catarrhs, and other pulmonary affections not inflammatory in their character. It is usually preferred on account of its more agree- able flavor, and for which it is often added to expectorant mixtures. The vapor of an ethereal solution of this balsam is said to be beneficial in old and obstinate coughs, when inhaled. Two parts of Tolu, three of almond oil, four of gum arabic, and sixteen of rose-water, make an excellent liniment for excoriated nipples. The dose is from ten to thirty grains, frequently repeated, and given in tincture, syrup, or similar to Balsam of Peru. Off.

THE UNRIPE BERRIES. Description. — This tree, the Eugenia Pimenta of De Candolle, is a handsome evergreen, with a straight trunk about thirty feet high, much branched toward the top, and covered with a smooth gray bark; the twigs are compressed, the younger and the pedicels downy. The leaves are opposite, on short petioles, oblong-lanceolate, smooth, shining, pointed, deep-green, about four inches long, and when recent abound in an essential oil, and have an aromatic taste. The flowers are small, numerous, and disposed in axillary and terminal panicles upon trichoto- mous stalks. The calyx is formed of four roundish sepals. The petals are four, reflected, greenish-white. The stamens are numerous, longer than the petals, of the same color, with rounded, white anthers. The style is simple, with an obtuse stigma. The fruit is a smooth, shining, succulent berry, crowned with the persistent calyx, of a black or pur- plish color when ripe, about the size of a pea, and containing two reni- form, flattish seeds. History. — The Pimento tree is a native of Mexico, the West Indies, and other parts of South America. It is abundant in Jamaica. The tree bears fruit when three years old, and arrives at maturity at seven; 654 Materia Medica. it grows best in a calcareous soil, covered with a light mold. The unripe berries are the officinal part, and are more generally known by the name of Allspice. Other names, as Jamaica Pepper, Bayberry, etc., have been given to them. They are gathered just before they are ripe, and carefully dried in the sun, and then put into bags or casks for exportation. When these trees are in blossom they exhale a most delicious fragrance. Pimento, or allspice when dried, becomes brownish-black, round, wrinkled, and umbilicate at the apex. It consists of an external, hard, brittle rind, which is yellowish internally, and which presents two cells when broken, each containing a dark-brown hemispherical seed. Its odor is strongly aromatic, combining that of cinnamon, cloves, and nut- meg, and the taste is warm, aromatic, pungent, and slightly astringent. Boiling water takes up the aroma, and alcohol all the active properties. The infusion is brown, and has an acid reaction on litmus paper. The berries are found to contain a volatile oil, which may be obtained by distillation, a green fixed oil, of a burning aromatic taste, a concrete, yellowish, flaky, oleaginous substance, tannin, gum, resin, uncrystalliz- able sugar, coloring-matter, malic and gallic acids, saline matters, moisture, and lignin. The seeds contain only half the proportion of volatile oil, and three times as much astringent extract. Properties and Uses.—Pimento is a warm aromatic stimulant and car- minative, and may be used where such agents are indicated. It is seldom employed in medicine, but is used largely as a hot aromatic in cookery; and sometimes it is added to other medicines to render them more agreeable. A tincture has been recommended as a local appli- cation in chilblains. Dose of the powder, from ten to thirty grains; of the tincture, from one to two fluidrachms; of the oil, from two to five drops. Off. Prep.—Aqua Pimenta ; Tinctura Guaiaci Ammoniata. NABALUS ALBUS. Lion's Foot. Nat. Ord.—Compositae, Tribe Cichoraceaa. Sex. Syst.—Syngenesia iEqualis. THE PLANT. Description—This plant, also known as While-Lettuce, and Rattlesnake Root, is the Prenanthes Albus of Linnaus. It is an indigenous peren- nial herb, with a smooth, somewhat glaucous stem, corymbose-panicu- late at the summit, stout, purplish, often deeply so in spots, and from two to four feet in hight. The radical leaves are angular-hastate, often more or less deeply three to five-lobed; the uppermost cauline ones, lanceolate, and between these the intermediate forms, hastate and ovate, Nectandra Rodi^ei. 655 petiolate, and all irregularly dentate. Heads pendulous, glabrous ; invo- lucre of eight linear scales, nine to twelve-flowered; scales purplish; corollas whitish. Pappus brown. There is a variety of the above plant, Nabalus Serpentaria or Prenan- thes Serpentaria, with rough dentate leaves, of Avhich the radical are pal- mate, the cauline with long footstalks, sinuate-pinnatifid, disposed to be three-lobed, with the middle lobe three-parted and the upper, lanceolate. The racemes are terminal, somewhat panicled, short, and nodding, with an eight-cleft calyx, and twelve florets; it is about two feet high, with purple flowers. History.—This plant is found in moist woods and shades, in rich soils, from New England to Iowa, and from Canada to Carolina, flowering in August. The variety N. Serpentaria is common to the mountainous districts of Virginia, North Carolina, and other sections of the United States, and is considered more active than the N. Albus. The root, leaves, and juice of the plant are employed. It has not been analyzed. Properties and Uses.—Said to be an antidote to the bite of the rattle- snake, and other poisonous serpents. The milky juice of the plant is taken internally, while the leaves steeped in water are to be applied to the wound, and frequently changed. A decoction of the root, which is bitter, has been successfully used in the bite of the rattlesnake, also in dysentery. This plant is deserving further and more accurate investi- gation. NECTANDRA RODLEI. Bebeeru. Nat. Ord.—Lauraceaa. Sex. Syst.—Dodecandria Monogynia. THE ALKALOID CONTAINED IN THE BARK. Description.—This is a magnificent forest tree, growing from sixty to eighty feet in hight, branching near the summit, and covered with a smooth ash-gray bark. The leaves are nearly opposite, smooth, shinincr, coriaceous, five or six inches long, and two or three broad. The flowers are obscure, whitish-yellow, cordate, and disposed in axillary panicles. The fruit is a globular berry, about six inches in circumference, having a woody, grayish-brown, speckled pericarp, and a seed with two large plano-conyex cotyledons, which is yellow when freshly cut, and possesses an acid reaction and an intensely bitter taste. The fruit abounds in bitter starch. History.—This tree is a native of British Guiana, and its bark has been recently brought into notice by Dr. Rodie, as a powerful tonic and febrifuge. It is in flat pieces of one or tAvo feet in length, from two to six inches broad, and about four lines in thickness, hard, heavy, brittle, with a rough fibrous fracture, dark-cinnamon-brown and rather smooth 656 Materia Medica. internally, and covered externally Avith a brittle grayish-brown epider- mis. It has little or no odor, but a strong persistent bitter taste, with considerable astringency. The fruit is as large as a small apple, obovate, or obcordate, somewhat compressed, consisting of an external brittle shell, and an interior fleshy kernel. It is likewise intensely bitter. The Sulphate of Bebeerina is obtained from the bark and seeds. The pro- cess for obtaining it is essentially the same as that for sulphate of quinia. The bark is at first freed of tannin and coloring matter by boiling it with carbonate of soda; it is then exhausted by boiling in water acidulated with sulphuric acid, and the alkaline matter is thrown down from the concentrated acid liquor by means of carbonate of soda. The impure bases thus separated are washed, dissolved, and neutralized with weak sulphuric acid, and the solution is treated with animal charcoal, concen- trated, filtered again, and finally evaporated in thin layers in flat ves- sels. Any excess of acid must be carefully avoided, otherwise the salt will be charred on evaporating it to dryness. The sulphate of bebeerina of the shops, contains both bebeerina and Sipeerina, another alkaline principle also discovered by Dr. Rodie. It occurs in thin, somewhat glittering scales of a brownish-yellow color, (sometimes with a greenish tinge,) and forming a yellow powder. It is inodorous and has an intensely bitter, persistent, and somewhat astrin- gent taste. Like the Sulphate of Quinia it requires an excess of acid for its perfect solution; hence the addition of a few drops of diluted sul- phuric acid renders its solution more complete. It is also soluble in spirit. When well prepared, the scale-like particles should be glittering and translucent, and ought, when incinerated to leave no ash, or a mere trace only. In this way, sulphate of lime, the only important impurity which has been found in it, may7 be easily detected. When carefully dried, it contains 90.83 per cent, of base, and 9.17 of sulphuric acid. Pure Bebeerina may be obtained as follows: Decompose the commer- cial sulphate by ammonia, and carefully wash the alkaline precipitate with cold water, and while still moist, triturate it with an equal weight of freshly precipitated and moist hydrated oxide of lead. The magma thus formed is then dried over the water-bath, and the alkali is taken up by absolute alcohol. On distilling off the spirit, the organic base is left in the form of a transparent orange-yellow resinous mass, containing Sipeerina. This is dried, pulverized, and treated with successive por- tions of pure ether, which dissolves the bebeerina, leaving the sipeerina behind. The ether is distilled and evaporated, and pure bebeerina is obtained in the form of a translucent, amorphous, but homogeneous resi- nous-looking substance, of a pale-yellow color, and possessed of all the properties of an organic alkali. Bebeerina does not crystallize; it is very soluble in alcohol, less so in ether, and very sparingly in water. When heated it fuses; and the heat being continued, it swells up, giving off vapors of a strong peculiar odor and burns without residue. It forms NECTANDRA R0DLhur, are made by boiling them for a long time with sulphur. Chlorine or iodine con- verts them into resin, and then combines with the resin. They unite with several vegetable acids, but are decomposed by the strong mineral. Caustic alkali converts them into resin, which unites with the alkali and forms soap. Several metallic oxides, and various salts which easily part with oxygen, convert them into resin. They dissolve fixed oils, fats, resins, camphor, and several of the vegetable alkalies. The volatile oils consist of two distinct principles, Stearoptene or a solid matter, and Elcoptene or a fluid. These principles congeal at diffe- rent temperatures, and may be separated by pressing the oil, when frozen, between folds of bibulous paper, the stearoptene remains between the folds, while the eleoptene is absorbed by the paper, and may be obtained from it by distillation Avith water. Stearoptene is often deposited by volatile oils upon standing, in a solid crystalline form; sometimes these deposits are oxides, and when formed under the influ- ence of water, are frequently hydrates of the respective oils. The ultimate constituents of the volatile oils are usually carbon, hydrogen, and oxygen ; some of them contain nitrogen, and the oils of horseradish and mustard contain sulphur. Volatile oils leave a greasy stain upon paper, which disappears by heat; this is not the case with fixed oils, and they should always be preserved in small, well-stopped bottles, and excluded from the light. Volatile oils are frequently adulterated with fixed oils, resinous sub- stances, and alcohol. Fixed oils may be known by their leaving a per- manent greasy stain upon paper, while that produced by the volatile oil disappears entirely when exposed to heat. When the adulterated oil is distilled with Avater, both resin and fixed oil remain behind. Alcohol may be detected by the milkiness of the oil when agitated with water, and, after the liquids have separated, the water occupies more space and the oil less than before. Various methods have been recommended to detect the presence of alcohol with essential oil. M. Beral puts twelve drops of the suspected oil in a perfectly dry watch-glass, and then adds a piece of potassium about as large as the head of a pin. If the potas- sium remain for twelve or fifteen minutes in the midst of the liquid, there is either no alcohol present, or less than four per cent.; if it dis- appear in five minutes, the oil contains more than four per cent, of alcohol; if in less than a minute, twenty-five per cent, or more. M. Borsarelli introduces small pieces of chloride of calcium, well dried and perfectly free from powder, into a small cylindrical tube, closed at one end, and about two-thirds filled with the oil to be examined, and heats the tube to 212°, occasionally shaking it. If there be a considerable proportion of alcohol, the chloride is entirely dissolved, forming a solu- tion which sinks to the bottom of the tube; if only a very small quantity, Olea. 671 the pieces lose their form, and collect at the bottom in a white adhering mass; if none at all, they remain unchanged. J. J. Bernoulli adds dry acetate of potassa to the oil; if alcohol be present the salt is dissolved, forming a solution from which the volatile oil separates. If the oil be free from alcohol, the salt remains dry therein. Wittstein, who speaks highly of this test, has suggested the following mode of applying it as the best: In a dry test-tube, about half an inch in diameter, and five or six inches long, put not more than eight grains of powdered dry acetate of potassa; then fill the tube two-thirds full with the volatile oil to be examined. The contents of the tube must be well stirred with a glass rod, taking care not to allow the salt to rise above the oil; afterward set aside for a short time. If the salt be found at the bottom of the tube dry, it is evident that the oil contains no spirit. Oftentimes, instead of the dry salt, beneath the oil is found a clear syrupy fluid, which is a solution of the salt in the alcohol, with which the oil was mixed. When the oil contains only a little alcohol, a small portion of the solid salt will be found under the syrupy solution. Many oils frequently contain a trace of water, which does not materially interfere with this test, because, although the acetate of potassa becomes moist thereby, it still retains its pulverulent form. A. Oberdofl'er places from two to four drachms of the suspected oil in a flat glass plate, in the middle of which is placed a small glass stand (the inverted neck of a six-ounce bottle is very suitable for this purpose) on which a watch-glass, Avith five to ten grains of platinum-black, is supported, and the whole covered with a glass bell open at the top. After a strip of moistened litmus paper has been laid over the vessel containing the platinum-black, the operator observes the reaction. In the course of a few minutes, oil containing alcohol, begins to redden the litmus paper, which, in the space of a quarter or half an hour, is completely accomplished; upon which, the eliminated vapor of acetic acid is deposited on the interior of the glass bell if the alcohol Avas present in sufficient quantity, and can be recognized dis- tinctly by its odor. To remove all doubt, he washes the platinum-black, after an hour has elapsed, with a little water, filters, saturates the filtrate carefully with potassa, and adds neutral chloride of iron, by which the characteristic color of acetate of iron is obtained; and, after boiling, the fluid becomes decolorized, and the hydrated oxide of iron is precipitated. From a series of experiments, he concludes that it is possible, in this way, to detect the presence of one to two per cent, of alcohol, and that with five per cent, the odor is sufficient, with most oils, to prove the admixture of alcohol. How far this method may be interfered with, by some oils which have very acid reactions, or particularly pungent odors, experience must teach; but with a great number of oils, it has been found available, even with oil of bitter almonds. It is frequently the case, that volatile oils of small value are mixed with the more costly; these may be detected by their taste, smell, and 672 Materia Medica. specific gravity. Oil of turpentine, which is a common adulteration, may be known by remaining in part undissolved, when the oil is treated with three or four times its volume of alcohol of the specific gravity 0.84.

OLEUM BUBULUM. Neats-foot Oil. THE OIL PREPAKED FROM THE BONES OF THE BOS DOMESTICUS. Preparation.—The feet of the ox, having been deprived of the skin and hoof, are subjected to a long-continued boiling in water ; the oil and fat existing in them being melted, rise to the surface, from which they are removed, and again placed in fresh water, which is heated to nearly 212°. After standing for some time, various impurities settle at the bottom, and the oil is taken from the surface. If further purification is desired, it is to be again placed into water, and kept for twenty-four hours at such a temperature as will permit the fat that remains with the oil to separate from it. After the liquid has cooled, the fat concretes into a mass, and the oil remains in the state of a thin fluid, which is to be filtered through small pieces of charcoal, free from powder. History.—Neats-foot Oil, when purified properly, is a yellowish, inodorous, and bland liquid ; but in general, it retains both a disagreeable Oleum Morrhu^e. 673 odor and taste. It congeals with much difficulty, remaining fluid at very low temperatures, and is used for greasing machinery in order to lessen friction, likewise by saddlers and shoemakers, to soften and preserve leather, and prevent its cracking. Properties and Uses.—This oil is emollient and relaxant, and may be applied with advantage to the breast and throat, in croup or cough, rub- bing it on with brisk friction. It likewise enters into various extempora- neous liniments and poultices. OLEUM MORRHUJ2. Cod Liver Oil. A FIXED OIL OBTAINED FROM THE LIVER OF GADUS MORRHUA. Description.—The Gadus Morrhua of Linnams, and Morrhua vulgaris of Storer and other Naturalists, or the common Cod-fish, belongs to the Class Pisces, Order Jugulares (Linnaeus)—Malacopterygii Subbrachiati, and Family Gadidse ; its Generic character is recognized by the ventrals attached under the throat, and attenuated to a point. The fish is usually between two and three feet long, with brown or yellowish spots on its back. The body is moderately elongated and somewhat compressed, and covered with soft, rather small scales, of which the head is destitute ; of the fins, which are soft, there are three on the back, two anal, and a distinct caudal; and the fin under the throat is narrow and pointed. The jaws are furnished with pointed irregular teeth in several ranks. The gills are large with seven rays. It inhabits the Northern Atlantic Ocean, and is found in abundance on the banks of Newfoundland. History.—Cod-liver Oil, as it is generally called in commerce, is obtained from several of the species of the Genus Gadus — as the codfish, coal- fish, and burbot; and sometimes from the pollock, hake, and haddock. The oil is obtained by several processes ; one of which is to heat the livers with water, until they are broken up into a pultaceous mass, and then throw them upon a strainer placed over some vessel into which the liquid flows, the oil rises to the surface, from which it is drawn off, strained, and prepared for market. Another and improved plan is to heat the livers in a large vessel by steam externally applied, and then drain the pultaceous mass as in the other process. The oil is said to be sometimes procured by expression. Again, it is obtained by the putre- factive decomposition of the livers, when placed in quantities in barrels or other vessels, the oil rising to the surface as it escapes from the dis- integrating tissue. There are three varieties of Cod-liver Oil in commerce : 1st. The White or Pale-yellow, which is prepared from fresh sweet livers, and varies in color from the slightest tint of transparent yellow to a fine golden yellow ; 2d. The Brownish-yellow, obtained from livers running 43 674 Materia Medica. gradually to putrefaction, and of a chestnut-brown color; and 3d. The Dark-brown, prepared from livers in an intermediate state, dark-brown, and somewhat opake, except in thin layers. They are generally of the consistence of sperm oil, and have a peculiar odor and taste unlike all other oils, and which properties, in a great measure, are the best tests for the genuineness of the oil. The smell and taste is similar to that of shoe-leather, as prepared in this country, and when a decided odor of ordinary fish oil is present, we may suspect its purity. All the varieties have an acrid taste, together with a somewhat empyreumatic bitterness in the most impure. The specific gravity at 72° F. varies from 0.915 to 0.9195; at 63° F., the specific gravity of the pale variety is stated as 0.923 ; of the light-brown 0.924, and of the dark-brown 0.929. According to analysis, numerous principles have been found in Cod- liver Oil, as gaduin, oleic and margaric acids, butyric and acetic acids; various biliary principles, as fellinic, cholic, and bilifellinic acids, and bilifulvin ; a peculiar substance soluble in alcohol; a peculiar substance insoluble in water, alcohol, or ether ; iodine, chlorine, and traces of bro- mine ; phosphoric and sulphuric acids, phosphorus, lime, magnesia, soda, and iron. Dr. Winckler has shown that a distinguishing feature of cod-liver oil, consists in its having no glycerin, but in its place, the hydrated oxide of propyl. Gaduin may be obtained by saponifying the oil with soda, decompos- ing the soap by acetate of lead, and treating the resulting lead soap with ether, which dissolves the oleate of lead and gaduin, leaving the marga- rate of lead behind. The ethereal solution, which is dark-brown, is decomposed by sulphuric acid, which liberates the brown oleic acid. This owes its color to gaduin, to separate which soda is added in excess; the resulting oleate of soda, which is insoluble in an excess of the alkali, is dissolved in alcohol ; and the alcoholic solution is cooled below 32°, by which means the oleate of soda is separated, the gaduin remaining in solution. This is precipitated from its solution by the addition of sulphu- ric acid. Gaduin is a dark-brown substance, brittle and pulverizable when dry, without odor or taste, insoluble in water, and soluble to some extent in alcohol or ether. It is insoluble in nitric and muriatic acids, but is dissolved by sulphuric acid, giving a blood-red color to the solu- tion, from which it is precipitated by water and the alkalies. Alkaline solutions dissolve it; chlorine decolorizes it. It is gradually changed into a blackish-brown insoluble substance, by boiling in alcohol. Its for- mula is G>5 Hy; Oo. It is not supposed to be connected with any of the virtues of the oil. The virtues of Cod-liver Oil have been supposed by many to be owing to its bromine and iodine, but these exist in it in too small proportion for much effect. The usual tests cannot detect the pre- sence of the iodine ; the oil must be first saponified, and this carbonized before the iodine can be detected. The oil, although capable of dissolving Oleum Morrhu^e. 675 a laro-er proportion of iodine, never contains over one part of it in 2000; and if any specimen contains more, it is, probably, fraudulently added. Cod-liver Oil is liable to adulteration with other fixed oils ; for the detection of this there are no perfectly reliable tests. The best, are the peculiar shoe-leather smell and taste ; and if a strong lamp-oil odor is perceptible, the oil is impure. The color of the oil is of but little import- ance, though the pale or light-brown variety is generally esteemed the most. A drop of concentrated sulphuric acid added to a small portion of fresh cod-liver oil, causes a fine violet color, soon passing into yellow- ish or brownish-red; sometimes it immediately becomes a clear red, or dark-brownish red, without assuming the violet hue, and which is said to occur with oil prepared by boiling the livers with water. Concen- trated nitric acid agitated with the oil, produces instantly a pinkish color which soon becomes brown. Dr. Jongh states that a few drops of concentrated sulphuric acid, change olive oil to a dirty gray color; oil of poppies to a deep-yellow inclining to brown ; and ordinary fish oil to a deep-brown color; but when added, drop by drop, to cod-liver oil, a peculiar centrifugal move- ment is produced from the spot at which the drops fall, and at the same time a beautiful violet tint, which is instantly changed into purple by agitating the oil. This change of color is not owing to the presence of iodine, for other fish-oils which contain iodine do not manifest a similar change, but, as he believes, to the presence of a biliary principle called Cholinic Acid. This method, however, although it will distinguish the cod-liver from every other oil, will not answer to distinguish its various adulterations with other fish or vegetable oils. The pure cod-liver oil contains in 100 parts from 0.020 to 0.030 parts of iodine, and oils con- taining a less proportion of this substance, are to be considered as adul- terations or mixtures with non-remedial oils. Other oils, when mixed with iodine or various iodurets, maybe readily detected by their yielding these articles to water or alcohol when agitated with them, while genuine cod-liver oil never gives up its iodine to these fluids. The genuine oil, when carbonized, without being first saponified, and the carbon then separated by means of alcohol, does not betray the least trace of iodine, while other oils treated in the same manner are invariably detected by manifesting the presence of iodine or any of the medicinal iodurets. Again, the genuine oil, when saponified, never communicates to the mother water the slightest trace of iodine, while the contrary is the case when other oils combined with iodine, either in a free state or in any of its combinations, are subjected to saponification. Exposure to the air effects a change in the properties of the cod-liver oil, consequently it should always be kept well stopped; and the best mode of keeping it, is to fill bottles with it, which are of sufficient size to contain the quantity generally wanted for use at one time, and have 676 Materia Medica. them well stopped. By this means it may be kept for some time without any sensible change. Properties and Uses.—Cod-liver Oil is nutritive and alterative. It has been long used as a domestic remedy in chronic rheumatic and strumous diseases, especially in the northern parts of Europe, and has been in general medical use, only since the treatise upon it by Professor Bennett of Edinburgh, in 1841, although employed occasionally in the profession as early as 1766. The diseases in which it is said to be most efficient are chronic rheumatism, strumous diseases, enlargements of the glands, strumous ophthalmia, pseudo-syphilis, in scrofulous constitu- tions, various chronic cutaneous diseases, and even phthisis. Gout, caries, rachitis, and tabes mesenterica, have, it is said, yielded to its influence. It is also asserted to have been found useful in diseases of the joints and spine, lupus, obstinate constipation, worms, and inconti- nence of urine ; and may be advantageously employed in all chronic cases, in which the disease appears to consist mainly in impaired diges- tion, assimilation and nutrition. Externally, used in opacities of the cornea, a drop or two placed on the cornea with a camel's hair pencil, also in various chronic cutaneous diseases, rhagades, chaps, eczema, excoriations and fissures. Dose, half a fluidounce, twice a day, or more; but it is best to begin with small doses at first, say one drachm only, in order to lessen the risk of nausea and vomiting. Patients soon accustom themselves to its use, without repugnance. It is best given alone, fol- lowed by some claret, or a little sugar and cinnamon powder, or prepared with aromatic oils, the same as castor oil, which see. Its use is contra- indicated in plethora, or where there is a strong tendency to it. When long used, it is said to frequently occasion an eruption on the surface of an eczematous character. But little advantage will be apparent from the administration of cod-liver oil, until its use has been persevered in for five or six weeks, though it often commences earlier. Whether it deserves all the encomiums passed upon it, or is as efficient an agent as stated, in the various forms of disease in which it has been recommended, is yet a matter of some uncertainty; time is required to fully and cor- rectly ascertain its merits. Dr. Jongh prefers the darker colored oils, which he thinks act more promptly than the paler kinds. He considers this to be owing to their different chemical composition, which varies according to the mode adopted in obtaining them ; by analysis he has shown that the lighter-colored oils are the richest in inorganic principles, while the darker-colored contain a greater abundance of the bilious prin- ciples and volatile acids, on the presence of which last constituents he believes their medical virtues chiefly to depend. Oleum Oliv^e. 677 OLEUM OLIV^E. Olive Oil. Nat. Ord.—Oleaceae. Sex. Syst.—Diandria Monogynia. OIL FROM THE FRUIT OF OLEA EUROP-iEA. Description. — The Olive tree is an evergreen, with hoary, rigid branches, and covered with a grayish-bark. It is usually from fifteen to twenty feet high, though frequently attaining a much greater size. The wood is hard and compact, of a dark-yellowish color, susceptible of a high polish. The leaves are opposite, subsessile, firm, lanceolate, entire, mucronate, two or three inches long, smooth, dull green above, hoary beneath, and with their edges somewhat reverted. The fiowers are small, whitish, and are disposed in opposite clusters in the axilla of the leaves, which are on short peduncles, erect, about half as long as the leaves, and furnished with small, obtuse, hoary bracts. The calyx is obtuse and four-cleft; the corolla is white, monopetalous, spreading, and divided into four ovate, obtuse segments. The stamens are two, shorter than the corolla, supporting large elliptical anthers, and a single, slender, erect style, with a bipartite stigma. The fruit is a smooth, oval drupe, of a violet color when ripe, of an unpleasant, bitter taste, but abounding in a bland oil, and inclosing an ovate, oblong, rugose nut. History.—The native country of the Olive tree is unknown, though supposed to be originally from Asia ; at present it is extensively culti- vated in the South of Europe, especially in Spain, Southern France, Sicily, and Italy. After its second year, it commences bearing fruit, and is in full bearing at six years, and is of long duration, perhaps cen- turies. There are several varieties of this tree, differing in the size and form of the leaves, and in the magnitude, color, and taste of the fruit. The bark of the olive tree was formerly used in medicine; it, together with the leaves, have an acrid and bitterish taste. In hot countries a morbid product exudes from the tree, incorrectly termed Olive-gum or Lecca-gum ; it consists of a resin, a peculiar crystalline principle called Olivin or Olivilin, and benzoic acid. This was formerly used in medi- cine, but is not employed at present. The fruit, gathered when not quite ripe, is hard and excessively acrid ; but when macerated in lime- water or an alkaline ley, and then pickled in brine, it constitutes the olive of commerce, a pleasant and highly esteemed article of diet. The only product of the plant which is officinal is the oil obtained from the fleshy pericarp of the fruit. The fruit is gathered just before they are fully ripe, or when it begins to redden, because if delayed until they are thoroughly matured, the tree will bear only in alternate years. It is carefully collected by hand, and the harvest completed, if possible, in one day ; it is then immediately carried to the mill, in which it is bruised, care being taken that the millstones are set far enough apart from each other as not to crush the nut. The pulp is put in bags and 678 Materia Medica. moderately pressed; the product obtained is of the first quality, and is called Virgin oil. The remaining marc is broken in pieces, moistened with hot water, and again pressed; the oil from this second operation is of an inferior quality, but sufficiently good for table use, and for pre- paring fine soaps—it constitutes the ordinary olive oil of commerce. The marc is again broken up, well soaked in water, allowed to ferment, and again submitted to pressure ; a coarse, inferior oil is obtained fit only for burning, plasters, coarse soaps, etc. Other varieties are intro- duced into the process in different countries. The finest oil comes from Provence and Florence, and sometimes from Genoa and Lucca; the commoner sort, termed Gallipoli oil, comes from Naples. The best quality is imported in glass bottles, or in flasks, surrounded by a net- work made of grass, and known as Florence flasks. Pure olive oil is an unctuous liquid, of a pale-greenish yellow tint, almost inodorous, and a bland, faintly sweet, oleaginous taste; it will keep for a long time without becoming rancid. Its specific gravity is 0.9153. It is only partially dissolved by alcohol, unless this be in large proportion, and is completely soluble in twice its volume of ether. At a temperature of 38°, a portion of it solidifies in white crystalline grains, which is a compound of margarin and olein; the liquid portion is uncom- bined olein. Olive oil contains in 100 parts, 72 of olein, and 28 of margarin. Margarin may be obtained by squeezing the crystals which form at a temperature of about 20° in bibulous paper; the paper absorbs the olein, and leaves the concrete margarin. Few vegetable oils contain so large a proportion of this solid principle. Olive oil is not a drying oil; it undergoes saponification when heated with alkaline solutions, freeing glycerin, and forming soluble salts in which the alkali is com- bined with several fatty acids. Nitrous acid, or nitrate of mercury converts it into a fatty principle, called Elaidin, which concretes at tem- peratures below 97°, and is converted by saponification into glycerin, and elaidic acid. When exposed to the air or heat, olive oil is apt to become rancid, acquiring a thicker consistence, a sharp taste, a disagree- able smell, and a darker color. It is often adulterated with oils of poppy seeds, rape seeds, etc., which may be detected by the aid of hyponitrous acid and heat, which, in the course of a few hours, renders the whole of the pure article a firm fatty mass—even if so little as five per cent., of any other oil be present, the consolidation is much less firm and more tardy. M. Diesel states that nitric acid colors pure olive oil green, but if it be mixed with rape oil, it becomes of a strong yellowish- gray color. Since the manufacture of lard oil, it has been extensively used to adulterate olive oil, and large quantities of it are exported annu- ally from this country to France for this purpose ; the reaction with nitric acid, will, probably, detect this adulteration. Properties and Uses. — Olive, or Sweet oil, as it is often called, ia nutrient, emollient, laxative, and anthelmintic. A fluidounce or two Oleum Kicini. 679 purges, but is uncertain and often ineffective. Used as a demulcent in catarrh and other pulmonary affections, as a laxative in irritation of the intestinal mucous membrane, as an emollient and antidote in poisoning by alkalies, with which it forms soap, but not as an antidote to opium, arsenic, copper, etc., in which cases its administration is improper. In poisoning by cantharides, on account of its being an excellent solvent of the active principles, it augments the danger. It is principally employed in the composition of liniments, ointments, cerates and plasters. As an article of diet, it is exceedingly improper for dyspeptics. Smeared over the skin, it is thought to be beneficial in the treatment of plague, scar- latina, and some other exanthematous affections. According to Mr. Sidney H. Maltass, a strong decoction of the leaves of the olive tree, given in doses of a wineglassful every three hours, has cured the most obstinate and severe forms of intermittent fever. He considers it more effectual than quinia. Off.

OLEUM RICINI. Castor Oil. Nat. Ord.—Euphorbiacese. Sex. Syst.—Moncecia Monadelphia. THE OIL OF THE SEEDS OF RICINUS COMMUNIS. Description.—Ricinus Communis, the Castor oil bush, in the United States is a herbaceous annual, with a white, frosted or glaucous, hollow, smooth stem, somewhat purplish toward the top, branching, and from three to eight feet in hight. In the East Indies and Africa, it becomes a tree attaining the hight of thirty or forty feet, and is peren- nial. The root is long, thick, and fibrous. The leaves are large, alter- nate, on long tapering purplish petioles, peltate, palmate, with seven or nine pointed, serrate lobes, smooth on both sides, of a bluish-green color. The flowers are monoecious, stand upon jointed peduncles, in long, green, glaucous, pyramidal spikes or racemes which spring from the divisions of the branches. The male flowers from the lower part of the spike, the females the upper; both are destitute of corolla. The calyx of the male flower is divided into five oval, concave, pointed, reflected, purplish segments, and incloses numerous stamens, which are united into fasciculi at their base. That of the female has three or five narrow lanceolate segments ; and the ovary, which is roundish and three- sided, supports three linear, reddish stigmas, forked at their apex. The fruit is a roundish, glaucous capsule, with three projecting sides, covered with tough spines, and divided into three cells, each containing 680 Materia Medica. one seed, which is expelled by the bursting of the capsule. Seeds, about as large as a bean, ovate, compressed, obtuse at the extremities, smooth and shining, of a gray or ash color, marbled with black or red- dish-brown spots and veins. History.—Ricinus Communis, or Palma Christi, is a native of India, and has become naturalized in many warm climates; it is extensively cultivated in many parts of the United States, where it flowers in July and August, ripening its seeds in August and September. The officinal part is the fixed oil obtained from the seeds. The seeds have a small yellowish tubercle at one end, from which an obscure longitudinal ridge proceeds to the opposite extremity, dividing the sides upon which it is situated into two flattish surfaces. Its variegated color depends upon a very thin pellicle, closely investing a hard brittle, blackish, tasteless, easily separable shell, within which is a thick, fleshy, oleaginous, white nucleus or kernel, inclosing a large, dicotyledonous, leafy embryo. From its resemblance to the dog-tick, the Latin name, Ricinus, was probably derived. The husk constitutes twenty-four per cent, of the seed, and consists chiefly of ligneous fiber, with a little gum, resin, and extractive matter. The nucleus constitutes sixty-nine per cent, of the seed when dry, and contains 46.19 parts of fixed oil, 2.40 of gum, 20.00 of starch and lignin, and 0.50 of soluble albumen. It must also con- tain a peculiar acrid and purgative principle, which has not yet been obtained, for it is powerfully active after the oil has been expressed. The seeds easily become rancid, and are then unfit for the extraction of the oil, which is acrid and irritating. The fixed oil is the officinal Castor oil. Castor oil is obtained from the seeds by three processes: First, by decoction; the seeds are deprived of their husks, steeped for a night in cold water, and then boiled for two hours in a fresh portion of water, dried in the sun and bruised, and lastly boiled in fresh water, and con- stantly stirred, till all the oil separates and rises to the surface; this is skimmed or strained off, and boiled with a small quantity of water to dissipate the acrid principle. The above process is the one said to be pursued in the East Indies; in the West Indies the same course is followed, except that the seeds are not steeped or boiled before being bruised. This mode is very apt to furnish an acrid and irritating product, and a brownish-colored oil. The second method is by alcohol, which process has been practiced in France, but the oil obtained is said to become speedily rancid, although very pure. The third method is by expres- sion, which is the one practiced in this country, and when properly conducted, gives a bland and colorless result. The seeds after having been thoroughly cleansed from dust and fragments of capsules, and other impurities with which they may be mixed, are placed into a shal- low iron-reservoir, where they are submitted to a very gentle heat, no greater than can be borne by the hand, and not sufficient to scorch or Oleum Ricini. 681 decompose them; this warmth renders the oil sufficiently liquid for easy expression. They are then placed into a powerful screw-press, and yield a whitish oleaginous liquid, which is transferred to vessels holding large quantities of water, and boiled for some time. As impurities rise to the surface they are skimmed off, until at last the clear oil only is left floating upon the surface, the albumen having been coagulated by the heat, forms a whitish layer between the oil and the water, and the muci- lage and starch are dissolved by the water. The oil is now carefully removed, and is again boiled with a minute proportion of water, for the purpose of clarifying it, and rendering it less acrid by driving off the acrid volatile matter; and the heat is continued till aqueous vapors cease to rise, and till a small portion of the oil, taken out in a vial, presents a perfect transparency when cooled. Care, however, must be taken not to push the heat too far, or else the oil will become brownish, and acquire an acrid peppery taste. One bushel of good seeds yields five or six quarts of oil. Sometimes, however, after expression, the oil is merely allowed to stand for a time, until all precipitation has ceased, and then the supernatant liquid is drawn off. When not carefully pre- pared, castor oil is apt to deposit a sediment upon standing; and the apothecary frequently finds it necessary to filter it through coarse paper before dispensing it. When pure, castor oil is a thick, viscid, colorless fluid, slightly odor- ous, with a sweetish, mildly nauseous taste, followed by a slight sense of acrimony. In the shops it is often found tinged with yellow, having an unpleasant smell, and occasionally brownish, with a hot acrid taste. The most esteemed castor oil is the cold drawn, which is made by expression without heat. It is one of the heaviest of the fixed oils, having a density of .964 at 60°. When exposed to cold a little below 32°, it slowly becomes thick and turbid, and at length deposits a very few crystalline grains of margarin, though it is stated that no margarin separates, if the oil has been previously heated to 212° either with or without water. At a temperature above 212° the oil itself becomes altered and acquires acrid properties. Exposed to the air it slowly thickens without becoming opake, acquires rancidity, and finally dries up; it belongs to the drying oils. It is insoluble in water, soluble in all proportions in alcohol or ether, and alcohol of the specific gravity of 0.842 takes up about three-fifths of its weight—a property not possessed by any other common fixed oil except the concrete palm oil. It readily combines with other fixed as well as volatile oils; the alkaline solutions dissolve and saponify it, producing acids termed the ricinic, ricinoleic, and ricino-stearic. Hyponitrous acid will convert twenty times its weight of castor oil in seven hours, into a firm, yellow, solid substance, called Palmin, which is saponifiable by alkalies, yielding Palmic acid and glycerin. Castor oil when added to other fixed oils, renders them more soluble in alcohol. It may be distilled at a temperature of about 510°, 682 Materia Medica. when it undergoes important alterations, yielding three acids, apparently identical with those above-named. The proximate constitution of castor oil, is imperfectly understood by chemists. It is stated that rancid acrid castor oil may be deprived of its disa- greeable odor and taste, as well as of its acrimony, by boiling it for fifteen minutes with water and a little calcined magnesia. If it be turbid, it should be clarified by filtration through coarse paper. Castor oil is much employed in the preparation of an article which is exten- sively sold throughout the country for bear's oil; it is composed of four fluidounces of castor oil, mixed with two fluidrachms of an aqueous solution of salts of tartar (carbonate of potassa) and scented with ber- gamot, lavender, or other aromatic oil. Properties and Uses.—The castor oil seed or bean is a powerful drastic cathartic and irritant, and has proved fatal to man when taken to the extent of twenty seeds at once. Yet the oil expressed from it is only a mild cathartic, operating promptly, producing thin, feculent, but not watery stools, causing but little griping or nausea. From its mildness of action, it is especially adapted to young children, pregnant or puer- peral females, likewise to hemorrhoidal affections, colic, diarrhea, dysentery, enteritis, after the reduction of hernia, obstinate constipation, collections of indurated feces, accumulation of acrid secretions, and in worms. One part of oil of turpentine mixed with three or four parts of castor oil increases its purgative and anthelmintic effect. The great- est objections to this cathartic are its nauseous taste and its tendency to cause sickness or unconquerable disgust. This may be overcome by adding to one pint of the oil half a fluidounce each of oils of origanum and wintergreen, or one ounce of sassafras oil; the dose of this may be given in sweetened water. Any other aromatic oils will answer equally as well. When not contra-indicated it may be taken in wine, spirituous liquors, or the froth of porter, likewise in cinnamon or peppermint water. I find it a very pleasant mode of administration to boil the dose of oil with about a gill of good sweet milk for a few minutes, sweeten with loaf-sugar, and flavor with essence of cinnamon or other favorite aroma- tic ; it somewhat resembles custard in its taste and appearance, and is readily taken by even the most delicate stomach. Stuncke states that castor oil saponifies readily with alkalies, and gives with soda a white solid soap, which, in the form of pills, is a certain and agreeable purga- tive. According to M. Parola, an ethero-alcoholic extract, and an ethereal or alcoholic tincture of the seeds, operate in much smaller doses than the oil, and with less disposition to irritate the bowels or to cause vomiting. As an enema, castor oil may be used in the quantity of two or three fluidounces, mixed with some mucilaginous liquid. Externally, it has been recommended in itch, ringworm, and other cuta- neous diseases. Dose, for an adult, a fluidounce or a fluidounce and a half; for an infant, one, two, or three fluidrachms, according to its age. Oleum Ricini. 683 Equal parts of castor oil and copal varnish, form an excellent local application for hemorrhoidal affections. We are informed by Dr. J. O. McWilliam that the natives of the Cape de Verd Islands, have common recourse to a remedy called "Bo- fareira," for the purpose of accelerating and increasing the flow of milk, not only from the breasts of childbearing women, where that secretion was tardy in appearing, or deficient in quantity when it did appear, but, on occasions of emergency, from the breasts of women who are not child bearing, or who have not given birth to, or suckled a child for many years. The leaves of the plant, Bofareira, are used, and which proved to be on investigation, the "Ricinus Communis," or common castor oil plant. The while bofareira is used, and carefully selected from the red bofareira, which appears to be a variety of the same species, but which they say is a powerful irritant, producing an immediate^nd often immoderate menstrual discharge, as has resulted in cases where it has been occasionally used in mistake. The white, or that which possesses galactagogue qualities, is recognized by the natives by the light-green color of the stem of the leaf, while the leaf stem of the red is of a purplish-red hue. In cases of childbirth, when the appearance of the milk is delayed (a circumstance of not unfrequent occurrence in those islands), a decoc- tion is made by boiling well a handful of the white bofareira in six or eight pints of spring water. The breasts are bathed with this decoction for fifteen or twenty minutes. Part of the boiled leaves, are then thinly spread over the breasts, and allowed to remain until all moisture ha.s been removed from them by evaporation, and probably, in some measure, by absorption. This operation of fomenting with the decoction and applying the leaves, is repeated at short intervals until the milk flows upon suction by the child, which it usually does in the course of a few hours. On occasions where milk is required to be produced in the breasts of women who have not given birth to, or suckled a child for years, the mode of treatment adopted, is as follows : two or three handfuls of the leaves of the Ricinus are taken and treated as before. The decoction is poured, while yet boiling, into a large vessel, over which the woman sits so as to receive the vapor over her thighs and generative organs, clothes being carefully tucked around her so as to prevent the escape of the steam. In this position she remains for ten or twelve minutes, or until the decoction cooling a little, she is enabled to bathe the parts with it, which she does for fifteen or twenty minutes more. The breasts are then similarly bathed, and gently rubbed with the hands; and the leaves are afterward applied to them in the manner already described. These several operations are repeated three times during the first day. On the second day, the woman has her breasts bathed, the leaves applied, and the rubbing repeated three or four times. On the third day, the 684 Materia Medica. sitting over the steam, the rubbing, and the application of the leaves to, with the fomentation of, the breasts, are again had recourse to. A child is now put to the nipple, and, in a majority of instances, it finds an abundant supply of milk. In the event of milk not being secreted on the third day, the same treatment is continued for another day, and if then there still be want of success, the case is abandoned, as the person is supposed not to be susceptible to the influence of the Bofareira. Women with well-developed breasts are most easily affected by it, while those with small and shriveled breasts have the uterine system acted upon, bringing on the menses, if their period be distant, or causing their immoderate flow if their advent be near. Exposure to cold is carefully avoided by women brought under its influence; they scrupu- lously abstain from wetting the hands or feet with cold water. It is said to affect virgins of adult age, similar to child-bearing women. It sometimes produces swelling and pain in the breasts and axillary glands, pain in the back, and an increase of a leucorrheal discharge. This remedy, and the red Bofareira, as an emmenagogue, both of which are common to this country, have been already tried by physi- cians, and the results have been sufficiently favorable to render further investigation very desirable.

History.—The term Turpentine is usually given to vegetable juices, liquid or concrete, and which consist of resin, and a peculiar volatile oil, separated by distillation, and called Oil of Turpentine. It is derived from the juice of the Yellow or Pitch Pine, Pinus Palustris, as well as other pines, and the Abies Balsam6a, etc. Beside the turpentines from these trees, there are others, as the common European Turpentine, Terebinthina Vulgaris, from the Pinus Sylvestris; the Larch or Venice Turpentine, Terebinthina Venela, from the Larix Europea and Abies Larix; the Chian or Cyprus Turpentine, Terebinthina Chia, or Cypria, from the Pistacia Terebinthus; the Bordeaux Turpentine, from the Pinus Maritima, and many others. All the turpentines are generally thick, of the consistence of honey, and of a light yellow or brown color; some are turbid, others are transparent, of a strong smell, sui generis, and of an acrid, bitter, and nauseous taste, The Venice turpentine is usually tolerably liquid, slightly greenish, of a strong, not unpleasant smell, and of a warm and bitter taste. The turpentines are readily soluble in ether or alcohol, and unite with fixed oils. All the terebinthinate pre- parations owe their medical properties to their volatile oil, and they are seldom used at present, except in salves, plasters, and the like. Oleum Terebinthinae. 685 Oil of turpentine is obtained by distillation of the turpentine with or without water; but in the latter case a much higher temperature is required, and the product is liable to be empyreumatic. The residue in the still, after the distillation of the oil, is resin. When it is necessary to obtain absolutely pure oil of turpentine, it should be redistilled from a solution of caustic potassa. Large quantities of the oil are distilled in North Carolina for exportation. The oil, or Spirits of Turpentine as it is frequently called, is, when pure, a clear, transparent, colorless, very liquid fluid, having the specific gravity of 0.86 at 72° F. It possesses a powerful, penetrating, balsamic, peculiar odor, and a disagreeable, aromatic, bitter, and sometimes acrid taste. It is lighter than water, is very volatile and inflammable, and boils at 312°, the temperature rising to 350° as the ebullition proceeds. A cold of—17° causes it to deposit white crystals, which are a hydrate of the pure oil. It burns with a fierce, dense, red flame and much black smoke. Exposed to the air it slowly absorbs oxygen and becomes yellow and thick, losing much of its activity. It is very sparingly soluble in water, moderately so in alcohol, and readily in sulphuric ether. It dissolves resins, fixed oils, fats, many alkaloids and neutral crystalline principles from the vegetable kingdom, and caoutchouc. When immersed in chlorine gas, it inflames; and iodine dropped into it is partly dissolved, and partly dispersed with an explosion. It absorbs muriatic acid gas in large quantity, forming with it two compounds, one a dense red liquid, the other a white crystal- line compound resembling camphor, and hence called Artificial camphor; this last consists of an equivalent of the acid, and one of the radical oil of turpentine or camphene, and is therefore a muriate of camphene. Nitric acid changes oil of turpentine into resin, and by long boiling, into turpentinic acid. Exposed to light and air oil of turpentine deposits a white solid matter in acicular crystals, which are inodorous and tasteless, insoluble in cold water, but soluble in ether or alcohol. The pure or radical oil is denominated Camphene, and consists of ten equivalents of carbon, and eight of hydrogen; but when kept for some time it always contains a little absorbed oxygen. Combined with one equivalent of oxygen, camphene forms camphor; and with two equivalents it forms camphoric acid. Properties and Uses.—The actions of oil of turpentine are complex. It is irritant, stimulant, cathartic, diuretic anthelmintic, and in relation to chronic mucous discharges, astringent. Given in large doses it occa- sions slight vertigo, or a sense of fullness in the head, with a feeling similar to that of intoxication, or a state resembling trance, attended frequently with nausea, and frequently followed by active catharsis; sometimes it creates pain in the stomach, sickness and vomiting; more frequently, especially when absorbed, it gives rise to violent strangury bloody urine, and other symptoms of irritation of the bladder and kidneys, at the same time imparting the odor of violets to the urine. 686 Materia Medica. If purgation occurs, the other effects seldom present themselves. In medicinal doses, it warms the stomach, quickens the pulse, increases the temperature of the surface, and in small doses, frequently repeated, it stimulates the kidneys, increasing the urinary secretion. In some persons, its internal administration occasions an erythematic eruption on the skin. As a stimulant it is particularly useful in the typhoid stage of various febrile diseases, where there is reason to suspect ulceration of the mucous membranes; as in cases where the tongue becomes dry and brown, the skin dry, and tympanitis present, with sometimes a slight delirium, the frequently-repeated use of small doses will remove all these symptoms, and the patient gradually recover. It is supposed, in these instances, to effect a healthy change on the ulcerated intestinal surfaces. It is likewise recommended in neuralgia, chronic rheumatism, dropsy, suppression of urine, worms, especially tenia—tympanitic dis- tension in typhoid fever, peritonitis, or other diseases—chorea, hysteria, croup, colic, jaundice, and in cases where gravel is habitually carried off by copious discharge of lithic acid, and lithate of ammonia. It has a tendency to diminish excessive mucous discharges, and has been employed with advantage in chronic catarrh, chronic dysentery, chronic diarrhea, chronic inflammation of the bladder, gleet, chronic gonorrhea, and leucor- rhea. The dose, in ordinary cases, is from five drops to half a fluidrachm, and even to one drachm, repeated every hour or two in acute disease, and every three or four hours in chronic. In the course of its action it is ab- sorbed, and imparts its odor to the breath and perspiration. In doses vary- ino- from twenty minims to a fluidrachm, according to the urgency of the symptoms, and repeated every three or four hours, it is a most efficacious astringent, and may be used in epistaxis, hematemesis, hemoptysis, and other sanguineous discharges. It may be administered in water, flavored with some ao-reeable aromatic syrup, or in infusion of matico, in hemop- tysis; in the decoctions of uva ursi, epigea, or eupatorium, etc., in hema- turia ; or in the decoction or infusion of Peruvian bark in purpura hemorrhagica. Where much arterial blood has been lost, muriated tincture of iron will form a valuable adjunct. Combined with castor oil, it is an excellent vermifuge. Externally it is a rubefacient, and is used as a counter irritant in the form of liniment in rheumatic and paralytic affections, various internal inflammations, in the neighborhood of indolent tumors, to chilblains, indolent and erysipelatous ulcers, caries, sloughing, especially from pressure in exhausting diseases, chronic inflam- mation of the edge of the eyelids, and in recent burns or scalds com- bined with linseed oil. Sometimes used in deafness arising from a de- ficient or unhealthy secretion of wax, mixed with some mild oil and introduced on cotton into the ear. In the form of enema, oil of turpen- tine has been employed in cases of amenorrhea arising from torpor of the uterine vessels, likewise in obstinate constipation, ascarides, and in tympanitis, or distension of the bowels from accumulations of air, in Oleum Terebinthinae. 687 which it is a superior remedy. From half a fluidounce to two fluid- ounces may be suspended in half a pint of water, or some mucilaginous liquid, by means of two yelks of egg, injected into the rectum, and retained there for some time. When given internally, it may be administered on sugar, or in emul- sion with gum Arabic, loaf sugar, and cinnamon or mint water ; or it may be triturated with the yelk of egg, gradually adding syrup, and essence of cinnamon, with a portion of water. One yelk is sufficient for trituration with every two fluidrachms of the oil. In tapeworm it has been combined with gin, and given in doses of one or two fluidounces. As an ordinary vermifuge, three or four parts of castor oil may be added to one part of the oil of turpentine. Dr. Jas. Warren has used a preparation for nearly thirty years in the treatment of hemorrhages, with uniform success. It acts both by its sedative power, in diminishing the force of the circulation, and by its astringent qualities, in contact with the bleeding vessels. He is satisfied that no remedy now known exerts a more specific power and more speedy relief, especially in hemoptysis, hematemesis, epistaxis, and menorrhagia. In the treatment of hemorrhage, neither bloodletting, confinement to the room, suppression of the voice, relaxation from busi- ness, nor other precautions are necessary; nor is any auxiliary treatment required, except, perhaps, a purgative dose where there is evidence that blood has been swallowed. Exercise in the open air is decidedly prefer- able to inaction; and wherever there are premonitory symptoms of a return of hemorrhage, it has always exerted a prophylactic power when promptly used ; and by this early resort to it, many radical cures have been effected. He terms it "Styptic Balsam." It is made as follows : Place sulphuric acid, five drachms by weight, in a Wedgewood mortar, and slowly add to it, oil of turpentine two fluidrachms, stirring it con- stantly with the pestle ; then add in the same manner Alcohol two fluidrachms, and continue stirring until no more fumes arise, when it may be bottled, and should be stopped with a ground stopper. It should be prepared from the purest materials; and when made should exhibit a dark but clear red color, like dark-blood ; but if it be a pale, dirty red, it will be unfit for use. The dose is forty drops, to be used as follows; into a common sized teacup put a teaspoonful of brown sugar, thoroughly incorporate the forty drops by rubbing together, and then slowly stir in water until the cup is nearly full, when it should be imme- diately swallowed. The dose may be repeated every hour, for three or four hours, and its use should be discontinued as soon as fresh blood ceases to flow. After standing a few days, a pellicle forms upon the surface of the balsam, which should be broken, and the liquid below it used. If in well-stopped bottles, age does not deteriorate it.—N. Y. Jour.

OLEUM TIGLII. Croton Oil. Nat. Ord.—Euphorbiaceaa. Sex. Syst.—Monoecia Monadelphia. the expressed oil of the seeds of croton tiglium. Description. — Croton Tiglium is a middle sized tree, the young branches of which are terete, smooth, shining, and somewhat furrowed toward the extremities. The leaves are alternate, petiolate, oval-oblong, acute, three to five-nerved at the base, acuminate at the apex, with shallow glandular serratures ; thin, membranous, with two glands at their base, covered when young with very minute stellate scattered hairs, dark-green above, and paler beneath. The petioles are about one-third the length of the leaf, channeled, having stellate hairs when quite young, but soon losing them. The flowers are downy, and arranged in erect, ter- minal racemes, the male flowers being at the apex, and the female below. The male flowers have a five-cleft calyx, five lanceolate, woolly, straw- colored petals, and fifteen distinct stamens ; the females have a five- cleft, permanent calyx, with long and bifid styles. The fruit is a smooth, oblong, obtusely triangular capsule, about the size of a hazel-nut, closely covered with minute stellate hairs, three cells, each of which is com- pletely filled with a solitary seed. The skin of the seeds is of a pale dull-brown color, and overlays a harder dark integument. History.—This tree is a native of the East Indies, and is cultivated in some parts of the West Indies. Like the other plants of the family Eu- phorbiaceae, it is pervaded throughout by an acrid purgative principle. The oil obtained from the seeds is the officinal portion. The seeds are of an ovoid or oblong form, rounded at the extremities, rather larger than a coffee grain, reddish-brown when recent, grayish-brown when old, sometimes brownish black. They consist of a thin, brittle, ligneous shell; a delicate, white, membranous integument; and an oleaginous kernel composed of a pale yellowish-white albumen, and a beautiful embryo, with large, leafy cotyledons. The oil is obtained by depriving the seeds of their shells, bruising them to a pulp, and subjecting the pulp to strong pressure. About fifty per cent, of oil is thus obtained, and ten per cent, more may be removed by digesting the residue with sulphuric ether, filtering, and expelling the ether by a gentle heat. It may likewise be obtained by decoction of the pulp in water. Guibourt Oleum Tiglii. 689 recommends after the first expression, to digest the residue with alcohol at a temperature of 120° to 140° F., and then submit it to a new expres- sion. Distil off the alcohol, and add the oil to the first product. Croton seeds yield upon analysis, a fatty acid called Crotonic acid, fixed oil, resin, traces of a volatile oil, stearin, wax, a magnesian soap with an alka- line reaction, called Crotonin, extractive, sugar, gum, starch, albumen, gluten, lignin, and salts. Crotonic acid is the supposed active constituent of the seeds, and passes out with the oil either by expression, by ether, or by alcohol. It may be obtained by saponifying the oil with solution of potassa, de- composing the resulting soap by tartaric acid, filtering and distilling the solution, neutralizing the acid product with barytic water, evaporating the solution to dryness, decomposing the barytic salt with strong phos- phoric acid, and again distilling. The acid thus obtained is crystalline at 23°, highly volatile, of an acrid taste, intensely irritating to the nostrils,, and forms salts with alkaline bases called Crotonates. The croton oil of commerce is partly imported from India, and partly expressed in England from the imported seeds. It varies in color from a pale amber color to that of deep-colored sherry, has a viscid consistence, like castor oil, which is increased by age, possesses a faint odor, a pecu- liar, hot, acrid taste, which is very persistent, and is felt most strongly in the back of the palate and throat. It is soluble in sulphuric ether, also in the volatile as well as fixed oils. The English oil is wholly and readily soluble in pure alcohol, forming a permanent solution at ordinary temperatures ; the India oil forms an opake mixture, which becomes clear and uniform upon being heated, but separates on standing into two layers, one of the alcohol somewhat diminished in bulk, the other of the oil, somewhat increased by a retention of part of the alcohol. It is sometimes adulterated with castor oil, which is difficult to detect in the English variety, but may be distinguished in the India oil by shaking the suspected article with absolute alcohol, which will dissolve the castor oil, and have but slight influence on the croton. It is stated that an oil weaker than the genuine croton is obtained from the Barbadoes' nuts, or the seeds of Jatropha Curcas ; it is an efficient cathartic in a dose of three or four drops. The seeds of the Croton Pavana are likewise supposed to furnish some of the croton oil of commerce. Properties and Uses.—Croton oil is a powerful irritant, and hydra- goo-ue cathartic. In large doses it is a dangerous poison, occasioning vomitino-, severe griping pain, hypercatharsis, and other serious symp- toms. Its action is prompt, frequently causing catharsis within an hour; and on account of its small dose it is especially adapted to cases where medicines requiring large doses cannot be given, as in mania, coma, and with children. A drop placed on the tongue of a comatose patient will generally operate. It is principally employed as a purgative when the 44 690 Materia Medica. bowels are very torpid ; in comatose diseases as a revellent; and in dropsy as a hydragogue. It is likewise asserted that, independent of its purgative property, it possesses efficacious influences in epilepsy, neural- gia, and spasm of the glottis. It may be used in all cases where prompt and active purgation is indicated. It is distinguished from other pow- erful cathartics by occasioning much borborygmus or rumbling of wind, by its action commencing speedily and ending soon, and by the purgative effect, however exhausting at the time, being followed by little debility. Externally, it produces erythematic redness, intense burning, and an eruption of minute vesicles. It should be diluted with three parts of olive oil, camphor liniment, oil of turpentine, or other convenient vehicle, and applied to the skin as a counter-irritant two or three times a day. Used thus it is beneficial in rheumatism, gout, neuralgia, indolent swell- ings, follicular disease of the throat, and pulmonary affections. The dose of croton oil is from one to six drops, which is best given on sugar, or made into a pill with crumb of bread, in order to avoid the disagree- able acrid sensation it occasions in the throat, with a constant tendency to hawk, as well as to prevent nausea or vomiting. Four drops of the oil, applied externally by friction around the umbilicus, will, it is said, produce catharsis. Off. Prep.—Ceratum Crotonis; Pilulae Gambogiae Compositae. OLIBANUM. The Frankincense of the Ancients. Nat. Ord.—Amyridacese, Burseraceas, (Lindley); Terebinthacea?, (De Can- dolle). Sex. Syst.—Decandria Monogynia. gum-resin of boswellia serrata. Description.—This is the Boswellia Thurifera of some botanists; it is a leafy forest tree growing on the Coromandel coasts and other parts of India. The leaves are- at the extremity of the branches, pinnate, consist- ing of about ten pairs of obliquely, oblong, obtuse, serrated, villous leaflets, with a terminal one; they are sometimes opposite, sometimes alternate, and on short, round, pubescent petioles. The flowers are in simple axillary racemes, shorter than the leaves, numerous, small, of a pale pink color, and furnished with minute bracts. The calyx is small, downy, and five-cleft; the petals are oblong and spreading, villous exter- nally, and longer than the stamens. Stamens are ten, inserted on the outer edge of a cup-shaped torus or nectary, which is crenated and fleshy, surrounding the ovary ; they are alternately shorter, and support oblong anthers. The ovary is superior, ovate, and bears a cylindrical style, with three-lobed stigmas. The fruit is a three-angled, smooth capsule, having three cells opening by three valves, and each containing Onosmodium Virginianum. 691 a single seed, which is broad, cordate at base, deeply emarginate, with a long, slender point. History.—There appear to be two varieties of frankincense, one from the above tree and one from a tree growing in the countries around the Red Sea, and which, it is stated, grows upon bare marble rocks, without any soil or even a fissure to support it, adhering by means of a substance thrown out from the base of the stem. It rises about forty feet, having short branches near the top, covered with a bright-green, singular foli- age. Olibanum consists chiefly of yellowish, somewhat translucent, roundish tears, and generally covered with a whitish powder, produced by friction. It has a balsamic, resinous smell, and an acrid, bitterish and somewhat aromatic taste. When triturated with water, it forms an imperfect milky solution. Alcohol dissolves nearly three-fourths of it, forming a transparent tincture. One hundred parts of it contain 8 of a volatile oil resembling that of lemons in color and smell, and which may be separated by distillation ; 56 of resin ; 30 of gum; 5.2 of a glutin- ous matter insoluble in water or alcohol, with 0.8 loss. Properties and Uses.—Olibanum is stimulant, like other gum-resins. Principally used for fumigations, and occasionally enters into some plasters. ONOSMODIUM VIRGINIANUM. False Gromwell. Nat. Ord.—Boraginaceas. Sex. Syst.—Pentandria Monogynia. the root and seeds. Description.—This plant is the Onosmodium Hispidum, of Michaux, and the Lithospermum Virginianum of Linnaeus; it is also known by the common names of Gravel-weed, and Wild Job's Tears. It is a perennial herb, clothed all over with harsh and rigid appressed bristles ; the stems are rather slender, and grow from one to two feet in hight. The leaves are oblong, or oblong-lanceolate, often oval, and even ovate-lanceolate, sessile, minutely strigose, three to five-veined, the lower ones narrowed at base, and from an inch to two and a half inches long, by half an inch or three quarters of an inch broad. The flowers are yellowish-white, in terminal leafy racemes, which are recurved at first but finally become erect and elongated. Calyx five-cleft, the lobes lanceolate, pilose on both sides, and half as long as the corolla. Corolla oblong-tubular, with a ventricose, half five-cleft limb, with lance-subulate segments, and clothed externally with long, hispid hairs. Stamens five, with very short flattened filaments supporting included, sagittate, apiculate anthers. Style much exserted, smooth. Achenia ovoid, smooth and shining, fixed by a flat base. History.—This plant is found growing from New York to Florida, in dry, hilly grounds, flowering from June to September. The root and 692 Materia Medica. seeds are the parts employed, and yield their virtues to water. There are two other species of this genus which possess similar properties. These are the Onosmodium Carolinianum, growing in rocky hills and along river banks from New York to Carolina and Tennessee; it grows from one to four feet high, has a stout, upright, soft, white pubescent stem, with stouter and larger leaves than the preceding variety; lobes of the corolla deltoid-ovate, obtusish, more or less hairy on the back; anthers oblong, longer than the narrow filaments, and silky-pubescent.—The other is the Onosmodium Strigosum, growing in the Western States, and found abundantly in Tennessee and Illinois in wet prairies and woods, on hill sides, and delighting, as it is said, in rich limestone soils. The stem is erect, simple, pilose-hispid, very leafy; the leaves are sessile, lance-linear, three inches long and one inch wide, three-veined, with appressed hairs, nearly smooth beneath the veins; bracts lance-linear, silky; calyx lobes linear, acute, silky with appressed hairs on both sides, very long; corolla cylindrical, larger than in the last, a third longer than the calyx, silky pubescent outside ; anthers linear, much longer than the vertically dilated filaments. Properties and Uses.—Diuretic and tonic. Said to be a solvent of calculus. A strong infusion of the root and seeds, taken every two hours for twelve or twenty hours, or until it operates as a cathartic, in doses of four fluidounces, is highly extolled as a cure for calculous affec- tions. Care must be taken that it be not continued too long, for fear of producing too great a flow of urine. It is worthy of a full investi- gation. ORIGANUM VULGARE. Origanum. Nat. Ord.—Lamiaceae. Sex. Syst.—Didynamia Gymnospermia. the herb. Description.—Origanum Vulgare or Wild Marjoram is a perennial herb, with erect, herbaceous, hairy, purplish, quadrangular, trichotomous stems, from six inches to two feet in hight. The leaves are opposite, petiolate, broad-ovate, obtuse, subserrate, hirsute, rounded at the base, green on both sides, sprinkled with resinous dots, and paler beneath. The petioles are hairy, and one-fourth as long as the leaves. The fiowers are numerous, of a pinkish purple or rose-color, and are disposed in smooth, erect, roundish, panicled, and fasciculate spikes, and accompanied with ovate, reddish bracts, longer than the calyx. The calyx is ovate, tubu- lar, striated, with nearly equal segments, and hairy in the throat. The corolla is funnel-shaped, about the length of the calyx, slightly two- lipped ; the upper lip suberect, bifid and obtuse, the lower trifid, blunt, and spreading. Stamens four, exserted, somewhat didynamous, with Ornus Europ^ea. 693 double anthers ; the stigma bifid and reflexed. Achenia dry, somewhat smooth. History.—Wild Marjoram is a native of Europe and America. It is found o-rowing along the road-sides, dry banks, and in dry stony fields and woods, flowering from June to October. The whole plant is offi- cinal, but is principally used for the extraction of its volatile oil, on which its virtues depend and which may be separated by distillation with water. The plant has a strong, peculiar, rather agreeable balsamic odor, and a warm, bitterish, aromatic taste, which properties are imparted to alcohol, or boiling water by infusion.— The Origanum Majorana, or Sweet Marjoram, possesses properties similar to the above species. It is a native of Portugal, but cultivated in our gardens, and much used in cookery as a seasoning. Its leaves are oval or obovate, obtuse, entire, petiolate, hairy pubescent; the flowers pink-colored, in compact, round- ish, pedunculate, terminal spikes, with roundish bracts. It flowers a month earlier than the preceding species; its odor is stronger, and more agreeable, and its taste more camphoraceous. Properties and Uses.—Origanum is gently stimulant, tonic, and em- menagogue. A warm infusion produces diaphoresis, and tends to pro- mote menstruation, when recently suppressed from cold. It is some- times employed externally in fomentation. Off.

Ord.—Oleaceae. Sex. Syst.—Diandria Monogynia. the concrete juice, manna. Description.—The Manna tree, or Flowering Ash, is a small tree, usually from twenty to twenty-five feet high, much branched, and covered with a smooth gray bark. The leaves are opposite, petiolate, and unequally pinnate, and consist of three or four pairs of leaflets, with a terminal one, which are opposite, oblong, or oval, acuminate, obtusely serrate, smooth, hairy at the base of the midrib on the under side, about an inch and a half in length, and of a bright green color; the petioles are channeled. The flowers are white, and usually expand with the leaves; they grow in dense panicles at the extremities of the young branches, on supra-decompound peduncles. The calyx is very short, with four ovate teeth ; the corolla, consists of four linear, lanceolate petals. The stamens are two, supporting long, yellow, incumbent an- thers. The ovary is oval, with a very short style, and a notched stigma. 694 Materia Medica. The fruit is a pendulous, compressed samara, containing a single, lanceolate, cylindrical, brown seed. History. — The manna tree is a native of most parts of Southern Europe, but thrives especially in Calabria and Sicily. The officinal part is the juice of the tree, known in commerce as manna. In Sicily the tree yields manna after its eighth year, and for some ten or twelve sub- sequent years, when it is cut down, and young sprouts allowed to grow up from the root. The manna exudes spontaneously from the bark, during the hot months, and concretes ; but in order to facilitate the process deep longitudinal incisions are made in the bark, on one side of the tree, from which the juice runs out, and speedily thickens. These incisions are made on one side of the trunk during one season; on the other side the next, and so on alternately as long as the trees yield manna. There are several varieties of manna, which chiefly differ from one another in quality according to the season and mode of collection. The Sicily manna is the most esteemed. The best and purest is the Flake Manna or Manna Cannulata, the Manna Gerace of the Sicilians; it exudes spontaneously, or by incisions during the hottest and dryest weather in July and August, and is usually collected on straw or clean chips which are stuck into the bark below the incisions, so that the juice may concrete upon them in easily detached stalactites. It is in irregular, unequal pieces, light, rough, brittle, dry, white, or pale yellowish-white, resembling stalactitic masses, about six or seven inches long, and an inch broad, hollowed slightly on the side by which they adhered to the tree, and frequently soiled by adhering frag- ments of bark or other impurities. They usually vary in length from one to seven inches, and have a crystalline or granular fracture. The next quality is Common Manna, or Manna-in-sorts, this is collected late in the season when the heat has begun to moderate, and the juice does not so readily concrete, but requires to be further dried in the sun. It is in whitish or yellowish fragments, similar to the flake manna but much smaller, mixed with a soft, viscid, uncrystallized brownish matter, and has a nauseous taste. Fat Manna is that collected in the latter part of the season, during cool and wet weather, in which the juice is still less disposed to thicken. It is soft, adhesive, not brittle, of a brown, or yellowish-brown color, and full of impurities. Manna is produced from several other trees beside the Ornus Eu- ropaaa, belonging to the genera Ornus and Fraxinus. Among which are more particularly the 0. Rotundifolia, F. Excelsior, and F. Parvi- flora. The Abies or Pinus Larix, yields a sweet exudation called Briancon manna, but which contains no mannite; the Hedysarum Alhayi of Syria, yields the Manna Mereniabin, an inferior manna; the Larix Cedrus produces the Manna of Lebanon; the Tamarix Gallica, the Manna of Mount Sinai; and the Eucalyptus Mannifera, a kind of manna called New Holland manna, containing a saccharine principle, but no mannite. Orobanche Virginiana. 695 Manna has a faint, peculiar odor, and a rather pleasant, sweet, some- what sharp, peculiar taste ; in the impure or inferior kinds the taste is also nauseous. When long kept it loses its white color, and gradually changes to a yellowish-red or brown. It softens with the heat of the hand, melts at a temperature somewhat higher, and is inflammable, burning with a blue flame. When pure it is almost wholly soluble in three parts of temperate, and in its own weight of boiling water. A saturated boiling aqueous solution on cooling deposits the manna in par- tially crystalline masses. It dissolves in eight parts of alcohol, and if a saturated solution be made by heat, on cooling, a deposit of beautiful crystals of manna will ensue. In consequence of its sugar, it is capable of undergoing fermentation. Analysis has found it to consist of mannite, sugar, a yellow, nauseous matter, mucilage, etc. Mannite may be ob- tained by boiling manna in alcohol, allowing the solution to cool, and redissolving the crystalline precipitate, when pure mannite is deposited. It is in white, acicular, four-sided prisms, in radiated tufts. It is sweet, inodorous, soluble in five parts of cold water, less so in alcohol, and not fermentable with yeast. Nitric acid converts it partly into oxalic, and partly into mucic acid. It consists of six equivalents of carbon, seven of hydrogen, and six of oxygen. One or two ounces will, it is stated, act as a gentle laxative. Good manna is seldom counterfeited, though the inferior sorts are, occasionally. A spurious article is said to be made of sugar and honey combined with some mild laxative. The inferior manna is likewise purified so as to resemble the flake variety; but all these frauds are easily detected. Properties and Uses.—Manna is a gentle laxative. Used for children and pregnant women, also in piles attended with constipation. Usually added to other purgatives to conceal their taste. Dose, one or two ounces, for an adult; from one to four drachms for children. It is usually prescribed with other purgatives, as rhubarb, magnesia, etc., but especially with senna. In large doses it is apt to cause flatulence and griping. OROBANCHE VIRGINIANA. Beech Drops. Nat. Ord.—Orobancheaceas. Sex. Syst.—Polyandria Digynia. the plant. Description.—This plant is the Epiphegus Americanus of Nuttall, the E. Virginiana of Barton, and is also known by the name of Cancer-root. It is a parasitic growth, with a smooth, fleshy, leafless stem, about a foot, or a foot and a half in hight, with slender and irregular branches given off the whole length of it. The root is scaly, and tuberous, covered with stiff, short, and brittle radicles. Instead of leaves it has only a few, scattered, inconspicuous, ovate scales, one at the base of each branch, 696 Materia Medica. of a yellowish or purplish color. The flowers are alternate, scattered on each branch, subsessile, the lower perfect and fertile, the upper usually imperfect and abortive. Calyx short, five-toothed. Corolla of the perfect flowers, two-lipped; the upper lip emarginate, the lower three-toothed; of the imperfect, slender, four-toothed, deciduous, six to eight lines long, curved, whitish and purple; the upper tooth or lip broadest, notched at the apex, arched, not longer than the others. Sta- mens as long as the corolla ; fllaments smooth ; anthers two-lobed, acute at the base, valveless, dehiscent in the middle. Stigma capitate, some- what emarginate. Capsule gibbous, truncate, oblique, one-celled, com- pressed, half two-valved at the apex, with two approximate placentae on each. Seeds very numerous, straw-colored, shining. History.—This plant is found in all parts of North America, growing upon the roots of beech trees, and flowering in August and September. The whole plant is of a dull-red color, without any verdure. It has a bitter, nauseous, astringent taste, which is diminished by drying. It yields its virtues to water. There are several other species of this genus, which are parasitic, and which possess analogous properties, as the Orobanche Uniflora, or one-flowered broomrape, and the Orobanche Americana, or American broomrape. Properties and Uses.—An astringent. Used with benefit in hemor- rhages of the bowels and uterus, and in diarrhea. Said to cure cancer, but it possesses no property of the kind. In erysipelas a decoction drank freely, and the parts bathed with it, has effected many cures. As a local application, the decoction or poultice will arrest the tendency of wounds or ulcers to gangrene; a poultice of equal parts of poke, white oak, and beech-drops is very useful in herpetic affections. Also useful as a topical application to obstinate ulcers, aphthous ulcerations, leucorrhea, gleet, etc. Dose, of the powder, from ten to fifteen grains. This plant seems to exert an influence upon the capillary system, somewhat similar to that produced by the tincture of muriate of iron. ORYZA SATIVA Rice. Nat. Ord.—Graminacea1. Sex. Syst.—Hexandria Digynia. the seeds deprived of their husks. Description. — Rice is an annual plant with a jointed culm or stem; leaves clasping; panicle terminal; glumes two, one-flowered; palea two, adhering to the ovary; stamens six; styles two. History.—Rice is supposed to have been originally a native of the East Indies, but it is at present cultivated in nearly all parts of the world, where the soil and climate are favorable. The ordinary commercial rice consists of the seeds of the plant divested of their husks. Carolina Osmorrhiza Longistylis. 697 rice, on analysis, has been found to consist of 85.07 per cent, of starch, 3.60 of gluten, 0.71 of gum, 0.29 of uncrystallizable sugar, 0.13 of a fixed oil, 4.80 of vegetable fiber, 5.00 of water, and 0.40 of saline substances. Properties and Uses.—Rice is nutritious; and boiled in water till per- fectly soft, is very useful in cases of debilitated stomach or bowels, and diarrhea; it is likewise reputed a valuable article of food to overcome the diarrhea so common to those who for the first time use the river waters of the Western States. It is by some considered injurious to the eyes when used in any quantity, but this is an erroneous opinion, as many nations employ it almost exclusively as a diet, without any such effects. A decoction of rice (rice-water) is an excellent soothing and nutritive drink in fevers, and inflammatory diseases of the lungs, stomach, bowels, and kidneys. OSMORRHIZA LONGISTYLIS. Sweet Cicely. Nat. Ord.—Apiaceae. Sex. Syst.—Pentandria Digynia. the root. Description. — This is the Uraspermum Claytoni of Nuttall; it has a perennial, thick, fleshy, branching root, of an agreeable, aromatic flavor, and an erect, nearly smooth stem, branching above, and growing from two to three feet high. The leaves are large, decompound, the ultimate divisions often pinnate; the radical leaves on long, slender petioles, the cauline sessile. The leaflets are irregularly divided by clefts and sinuses into lobes and teeth; the lobes broadly ovate, and slightly pubescent. The flowers are white, in axillary and terminal umbels, about five-rayed, the central ones barren, and the outer ones fertile. Calyx-margin obso- lete ; 2)ctals oblong, nearly entire, with a short inflexed point. Involucres of linear bracts longer than the rays. Style as long as the villose germ, filiform, erect, deflexed. Fruit linear-oblong, about an inch in length, angled, tapering downward into a stalk-like base, contracted at the sides, blackish, and crowned with the persistent styles. Carpels with five equal, acute, upwardly bristly ribs; commissure with a deep, bristly channel; intervals without vittae. History.—This plant grows in various parts of the United States, in rich moist woods, on the sides of low meadows, on the banks of running streams, and on the borders of low woodlands. It flowers in May and June. The root is the part employed, it has a sweet smell and taste, resembling aniseed, and yields its sensible properties to water or diluted alcohol. Properties and Uses.—Sweet Cicely is aromatic, stomachic, carmina- tive, and expectorant. Useful in coughs, flatulence, and as a gentle 698 Materia Medica. stimulant tonic to debilitated stomachs; the fresh root may be eaten freely, or it may be used in infusion with brandy or water. OSMUNDA REGALIS. Buckhorn Brake. Nat. Ord.—Filices (Lindley); Polypodiaceae (Brown). Sex. Syst.—Cryp- togamia Filices. the root. Description. — This is the Osmunda Spectabilis of Willdenow, often termed Royal Flowering-Fern. It has a hard, scaly, tuberous rhizoma, beset with numerous fibers, and having a whitish core in the center. The fronds are several, erect, three or four feet high, doubly-pinnate, smooth, bright-green, the primary divisions or pinnae from six to ten, nearly opposite, remote, hardly a span long. The leaflets are more numerous, often alternate, sessile or nearly so, oblong, bluntish, entire or obscurely-crenate with one rib, and numerous transverse veins; the base dilated, heart-shaped, or somewhat lobed. Some of the upper leaflets are cut, and as it were partially transmuted into dense clusters or spikes of innumerable, small, light-brown, veiny, globular, two- valved thecce entirely covering the segments; several of the upper divi- sions of the leaf consisting entirely of such thecae, composing a compound panicle. Spores green. History. — This beautiful fern is found in meadows and low, moist grounds throughout the United States, flowering in June. The main roots or caudex, is the officinal part, it is about two inches long, and somewhat in the shape of a horn. It consists of a number of longitudi- nal scales, lying over each other, and which have silky, transparent borders, with numerous small fibers or radicles, firmly matted together. It contains an abundance of mucilage, which is extracted by boiling water. The root should be collected in August, or about the latter part of May, and dried with great care, as they are apt to become moldy. The Osmunda Cinnamomea, or Cinnamon-colored Fern, is sometimes used as a substitute for the above, but it is inferior. Its root is similar to that of the above, in shape, but it is considerably larger. When its stems first appear in the spring, they are hairy and of a whitish color, surmounted by the young leaves, curiously rolled up in the form of a scroll, and covered with a downy or wool-like substance. Properties and Uses. — Mucilaginous, tonic, and styptic. Used in coughs, diarrhea, and dysentery; also used as a tonic during conva- lescence from exhausting diseases. One root, infused in a pint of hot water for half an hour, will convert the whole into a thick jelly. Very valuable in leucorrhea, and other female weaknesses, and said to be an almost certain cure for rickets, in doses of three drachms of the root, OSTRYA VlRGINICA. 699 three times a day. The mucilage mixed with brandy is a popular remedy as an external application for sprains, and weakness of the back. For internal use, the roots may be infused in hot water, sweetened, and ginger, cinnamon, brandy etc., added if not contra-indicated. OSTRYA VlRGINICA. Iron Wood. Nat. Ord.—Cupuliferas. Sex. Syst.—Monoecia Polyandria. THE INNER WOOD. Description. — This is a small tree from twenty-five to thirty feet in hight, remarkable for its fine, narrow, longitudinally divided and brown- ish bark. The wood is white, hard, and strong. The leaves are oblong- ovate, subcordate, acuminate, unequally serrate, somewhat downy; buds acute. Sterile flowers in cylindrical aments; scales orbicular-ovate acu- minate, ciliate, one-flowered; fllaments somewhat united irregularly; anthers bearded at the summit. Fertile flowers in pairs, numerous, in a short, oblong, pendulous, loosely imbricated, linear, terminal ament, with small deciduous bracts; scales none, but each flower is inclosed in a membranous sac-like involucre, bristly-hairy at the base, and which enlarges, forming a bladdery closed bag in fruit, these being imbricated to form a sort of strobile appearing like that of the Hop. Ovary two- celled, two-ovuled, crowned with entire and bearded border of the peri- anth, forming a small and seed-like smooth nut. Styles two, united at the base; nut lance-oblong, somewhat compressed, included in the enlarged, imbricated, bladder-like sac. History. — This plant, sometimes called Hop-hornbeam, Lever-wood, etc., is a tree common to the United States, growing in rich woods, and flowering in April and May. The flowers are green and appear with the leaves, and the large and handsome oval-oblong strobiles are matured in August. The inner wood and bark, are the parts used ; they are bitter, and yield their virtues to water. There is another tree, known as Iron- wood closely resembling the above, the Carpinus Americana; it grows from ten to twenty feet high, has a smooth gray bark, with an irregularly ridged trunk, and very fine-grained, compact, white wood. The scales of the fertile aments are three-parted, the middle segment being much the largest, oblique, with a lateral tooth, persistent, and becoming folia- ceous. The nut small, ovoid, bony, ribbed, with a simple, one-sided, enlarged, and open leaf-like involucre. This tree is not bitter, and must not be confounded with the Ostrya. Properties and Uses.—Iron-wood is antiperiodic, tonic, and alterative, It has been used with efficacy in intermittent fevers, neuralgic affections, dyspepsia, scrofula, and all diseases where an antiperiodic-tonic is indi- cated. Dose of the decoction, one or two fluidounces, three or four times a day. 700 Materia Medica. OVUM. Egg. THE EGG OF PHASANIUS GALLUS. History.—The Common Hen, Phasanius Gallus, supposed to have been originally the Jungle-fowl of India, is domesticated in nearly all parts of the globe. Its egg is the officinal product. It consists of an external shell, testa ovi or putamen ovi, composed chiefly of carbonate of lime, from which nearly pure lime is had by calcination; a lining mem- brane of an albuminous nature ; the white, and the yelk. The white, albumen ovi, is a glairy, colorless, transparent liquid inclosed in delicate membranous cells, inodorous, tasteless, and composed of twelve per cent, of albumen, 2.7 of mucus, 0.3 of saline substances with traces of sulphur, and eighty-five of water. It is soluble in water, coagulable by alcohol, the stronger acids, and by a heat of 160° F., and precipitated by corrosive sublimate, chloride of tin, chloride of gold, subacetate of lead, sulphate of copper, and tannin. Exposed in thin layers to a current of air, it becomes solid, retaining its transparency and solubility in water, and can be thus preserved a long time without change ; in this state, it may be applied in a state of solution to the same purposes as in its original condition. It soon putrefies when kept in the fluid state. The yelk, vitellus ovi, is a thick, opake, yellow fluid, inodorous, of a bland, oily taste, and when agitated with water forms an opake emulsion. When heated it is converted into a granular solid, from which a fixed oil may be obtained by expression. It contains 51.846 per cent, of water, 15.760 of vitellin, a peculiar albuminous principle, 21.304 of margarin and olein, 0.438 of cholesterin, 7.226 of oleic and margaric acids, 1.200 of phosphoglyceric acid, 0.034 of muriate of ammonia, 0.277 of chlo- rides of sodium, potassium, and sulphate of potassa, 1.022 of phos- phates of lime and magnesia, 0.400 of animal extract, and 0.553 of coloring matter, traces of iron, lactic acid, etc. Properties and. Uses.—Eggs are much employed in medicine and phar- macy. The shells, powdered and levigated, may be used in the same doses as prepared chalk, as an antacid in diarrhea. The white of egg is useful as a demulcent in diseases of the intestinal mucous membrane, and as an antidote for corrosive sublimate and the soluble salts of cop- per, with which it forms insoluble and comparatively inert compounds. In cases of redness or excoriation from pressure, it forms a good local application, used in the form of a liniment, made by agitating it briskly with its own volume of alcohol. It is used also for the clarification of liquids, which it accomplishes by undergoing coagulation, and envelop- ing suspended impurities in its flakes; for the suspension of insoluble substances in water; and for forming an astringent poultice, by being OXALIS ACETOSELLA. 701 agitated with a lump of alum ; the coagulum thus produced is applied, between folds of gauze, over the eye in some forms of ophthalmia. The yelk when raw is considered laxative, and is a popular remedy in jaundice, and dvspepsia ; probably, its effects in these complaints are owing to its easiness of digestion. It is mildly nutritious, and generally acceptable to the stomach, and may be used in dyspepsia, beaten up with water and a little ginger. It answers a better purpose than the white, in preparing emulsions and mixtures, being highly useful as an inter- medium between water and balsams, turpentines, oils, and other insol- uble substances. The oil expressed from the coagulated yelk is some- times used as an application to excoriated nipples. A non-collegiate practitioner in this county, has acquired some celebrity in the treatment of dyspepsia, loss of appetite, constipation, hemorrhoids, etc. ; the agent he employs is a powder composed of equal parts of the inner skin of chickens' gizzards (ingluvies pulli,) dried and pulverized, sulphur, and resin, of which from five to ten grains are to be taken three or four times a day. Off. Prep.—Linimentum Terebinthinae. OXALIS ACETOSELLA. Wood Sorrel. Nat. Ord.—Oxalidaceee. Sex. Syst.—Decandria Pentagynia. THE WHOLE HERB. Description.—Wood-Sorrel is a small, perennial, herbaceous, stemless plant, with a creeping and scaly-toothed root-stock. The leaves are numerous, radical, palmately three-foliate, on long, weak, hairy stalks; the leaflets are broadly obcordate, with rounded lobes, entire, pubescent, of a yellowish-green color, but frequently purplish beneath ; they close and droop at nightfall. Scape longer than the petioles, one-flowered, with two scaly bracts near the middle. Flowers white, yellowish at the base, delicately veined with purple, scentless. Stamens ten, monadel- phous at the base, alternately shorter; sepals fixe, persistent; petals five; style as long as the inner stamens. Capsule five-lobed, five-celled, oblong ; seeds several, with an elastic testa. History.—This plant grows in Europe and North America, in woods, groves, and hedges, but principally confined, in America, to the boreal and mountainous regions. It flowers in May, and is the Shamrock of the Irish. It is without smell, and has an agreeable, acid taste. It owes its acidity to binoxalate of potassa, which is sometimes prepared and sold under the name of Salt of Sorrel. This comes from Switzerland and Germany, where it is prepared from different species of oxalis and ruraex. The following process is employed: The plants previously 702 Materia Medica. bruised are macerated for some days in water, and then submitted to pressure. The liquid thus obtained is mixed with clay, and occasionally agitated for two days. At the end of this time, the clear liquor is decanted, and evaporated so that crystals may form when it cools. These are purified by solution and a new crystallization. Five hundred parts of the plant afford four parts of the acidulous salt. The same salt may be prepared by cautiously dropping a solution of potassa into a saturated solution of oxalic acid. The binoxalate crystallizes when a sufficient quantity of the alkali has been added. It is in rhomboidal crystals, of a sour, pungent, bitterish taste, soluble in ten times their weight of boiling water, much less so in cold water, and unalterable in the air. It is employed for removing iron-mold and ink stains from linen, and sometimes as a test for lime. It contains 72.48 parts or two equivalents of oxalic acid, 47.5 parts or one equivalent of potassa, and eighteen parts or two equivalents of water. The Quadroxalate of Potassa, or Essential Salt of Lemons is often substituted for the binoxalate. It is prepared in the same manner, except that, instead of one part, three parts of the acid are added to the original portion neutralized by the potassa. Used for the same purposes as the binoxalate; both are poisonous, though in a less degree than uncombined oxalic acid.— U. S. Dis. There are other varieties of this plant, possessing analogous proper- ties, as the Oxalis Stricta, and 0. Violacea. They all have ternate leaves with obcordate leaflets, and with the exception of 0. Violacea bear yellow flowers. Properties and Uses.—This and other species of Sorrel are refrigerant and diuretic. Useful in febrile diseases, hemorrhages, gonorrhea, chronic catarrh, urinary affections, and in scurvy. An infusion, or a whey made by boiling them in milk, may be used, or the herb may be eaten, but in neither case to excess, on account of the oxalic acid they contain. Externally, the bruised leaves, or inspissated juice have been found useful as an application to scrofulous, malignant and indolent ulcers. The Rumex Acetosa, or Garden Sorrel, R. Acetosella, or Sheep Sorrel, and R. Vesicarius possess similar properties, which see. P^EONIA OFFICINALIS. Peony. Nat. Ord.—Ranunculacese. Sex. Syst.—Polyandria Digynia. THE ROOT. Description.—Peony has many, thick, long, spreading, perennial roots, running deep into the ground, with an erect, herbaceous, large, green and branching stem, about two or three feet high. The leaves are large ; Panax Quinquefolium. 703 the lower leaves bipinnately divided; the leaflets are ovate-lanceolate, smooth, variously incised. The flowers are large, red, terminal, solitary; sepals five, unequal; petals red, cordiform ; stamens numerous, mostly changed to petals by cultivation. Carpels three; stigmas double, per- sistent ; follicles fleshy, many-seeded ; seeds black, numerous, dry, round. History.—This is a native of southern Europe, and is cultivated in gardens in the United States and elsewhere, on account of the beauty of its flowers, which appear from May to August. The root is the offi- cinal part; it consists of a caudex about as thick as the thumb, sending off spindle-shaped tubers in all directions, which gradually taper into thread-like fibers. It, together with the seeds, have when recent, a strong, peculiar, disagreeable odor, and a nauseous, sweetish taste, suc- ceeded by bitterness, acridity, and slight astringency; on drying it nearly loses its odor, and its taste is lessened. The flowers have a similar odor, and an astringent, sweetish, herbaceous taste. They all yield their vir- tues to diluted spirits. No analysis has been made of this plant. Properties and Uses.—Peony is antispasmodic and tonic. It has been successfully employed in chorea, epilepsy, spasms, and various nervous affections. In combination with white snakeroot, or black cohosh, it has proved valuable in pertussis. An infusion may be made by adding an ounce of the root in coarse powder to a pint of a boiling liquid, com- posed of one part of good gin, and two parts of water, which may be sweetened ; dose two or three fluidounces three or four times a day. Dose of the expressed juice of the recent root, one or two drachms; of the powdered root, a drachm three or four times a day ; of the powdered seeds from thirty to forty grains. The seeds taken night and morning, have been successfully used in removing the nightmare, attendant upon dropsical persons; they are also reputed emetic, cathartic, and anti- spasmodic. PANAX QUINQUEFOLIUM. Ginseng. Nat. Ord.—Araliaceae. Sex. Syst.—Pentandria Digynia, THE ROOT. Description. — Ginseng has a perennial, fusiform, whitish, thick and fleshy root transversely wrinkled, and terminating in fibers ; its upper portion slender and marked with the scars of former shoots. The stem, is round, smooth, green, often with a tinge of red, about a foot high, regularly divided at top into three petioles, with a flower-stalk in their center. Petioles round, smooth, swelling at base. The leaves are three, ternate, quinate or septenate. Leaflets pedicellate, obovate, sharplv serrate ac""-"'""*! 704: Materia Medica. veins above. The flowers are small, greenish, and arranged in a simple umbel, supported by a round, slender peduncle, which rises from the top of the stem in the center of the petioles. Involucre of a multitude of short subulate bracts, interspersed among the flower-stalks, which are so short as to give the appearance of a head rather than an umbel. Calyx with five small acute teeth. Petals five, oval, reflexed and deci- duous. Stamens five, with oblong anthers. Styles two, reflexed, per- sistent. Ovary large, inferior, ovate-cordate, compressed. Berries kidney-shaped, refuse at both ends, compressed, of a bright scarlet color, crowned with the calyx and styles, and containing two and some- times three semicircular seeds. The outermost florets ripen first, and their berries often obtain their full size before the central ones are ex- panded, the central florets are frequently abortive. History.—Ginseng is a native of most of the Middle and Northern States, and extends on the mountains far south, growing in rich soil and in shaded situations, and flowering in May. The root is somewhat spindle-shaped, from one to three inches long, about as thick as the little finger, and terminated by several slender fibers. When dried, it is yellowish-white and wrinkled externally, internally a hard central portion, surrounded by a soft whitish bark ; it has a feeble odor, and a sweet, pleasant bitter, slightly aromatic taste, and yields its properties to water or alcohol. Properties and Uses.—A mild tonic and stimulant. Useful in loss of appetite, slight nervous debility, and weak stomach. By some, it is con- sidered useful in asthma, gravel, convulsions, paralysis, to invigorate the virile powers, etc., etc. Dose of the powder, from ten to sixty grains ; of the infusion, from two to four fluidounces. PAP AVER SOMNIFERUM. Poppy. Nat. Ord.—Papaveraceae. Sex. Syst.—Polyandria Monogynia. THE CONCRETE JUICE OF THE UNRIrE CAPSULES. OPIUM. Description.—The Poppy is an annual plant, with a tapering and white root; the stem is round, erect, smooth, glaucous, often branched, leafy, and from two to four feet in hight; sometimes there are a few rigid hairs on the upper part of the stem. The leaves are large, alternate, ovate-oblong, incised and dentate, repand, amplexicaul. The flowers are large, terminal, white or silvery-gray, on long peduncles. The calyx is smooth, and consists of two ovate, concave, obtuse, sepals, which fall off on the expanding of the flower ; the corolla consists of four, roundish, spreading, undulated, and as it were, plaited petals, white with a violet spot at base. The stamens are very numerous, much shorter than the corolla, and terminated by oblong, compressed anthers. The ovary is Papaver Somniferum. 705 nearly globular, smooth, crowned with a flat, stellate stigma. The cap- sule is large, smooth, one-celled, but with partial dissepiments. The seeds are very numerous, small, of a whitish or gray color, somewhat reniform, escaping at maturity by openings under the stigma ; they are oily and destitute of any narcotic power. History.—There are several varieties of this species, the most promi- nent of which are termed the White and the Black Poppy. The white, Papaver Somniferum, has white flowers and seeds, and ovate capsules with no seed openings; the black, P. Officinale has colored flowers, dark seeds, and large globular capsules, with openings for the discharge of the seeds under the stigma. However distinct these may be naturally, by cultivation they run into each other, and seeds from the same capsule will furnish plants bearing flowers of different colors. The white poppy is generally described as the officinal opium plant, and is commonly supposed to be a native of Persia, though found growing wild in the South of Europe. At present it is extensively cultivated in India, Egypt, Turkey, and several parts of Europe, on account of its seed, capsules, and opium. In this country it is found only as a garden plant, although there is every reason to believe that it would prove a very lucrative branch of industry, not only from the opium it yields, but also from the oil to be had from its seeds, which is an excellent substitute for olive oil. In India the flowers appear in February ; in Europe and the United States from May to September. The officinal parts of the plant are the capsules, and opium, or the concrete juice from the cap- sules ; the seeds are employed for obtaining their oil. The capsules of the poppy, or poppy-heads, should always be gathered before they have ripened ; at this time they abound in the juice from which opium is formed, which in a great measure disappears on the ripening of the capsule. When dried, the unripe capsules possess the peculiar bitterness and narcotic qualities of opium, which is scarcely per- ceptible in those that have been suffered to come to maturity. The dried capsules are of various sizes, from that of a small egg to that of a large orange, they are of an ovate or globular form, flattened below, and sur- mounted by the persistent stigma. The capsules of the white poppy are larger than those of the black. They owe their virtues entirely to the opium contained in them. Poppy seeds are very numerous, a single capsule containing from 10,000 to 30,000. They are oleaginous and emulsive, and yield by expression a large quantity of a yellowish fixed oil, which, on being exposed for some time to the air, dries up into a varnish. The oil obtained is from one quarter to one half the weight of the seeds. It, together with the seeds, is inodorous, and has a bland and pleasant taste, without any narcotic properties. The oil is light, and transparent, and is used as food, likewise for painting, for burning, and for the manufacture of soap. 45 706 Materia. Medica. Opium is procured from the unripe capsules. The whole plant is said to contain a white, opake, narcotic juice, but in less quantity than the capsules. The mode of procuring it is as follows : A few days after the flowers have fallen, horizontal incisions are made in the capsule, care being taken not to penetrate its cavity; a white, milky fluid exudes, which is left for twenty-four hours, and then scraped off with laro-e dull knives ; each capsule furnishes but a few grains of opium. The epider- mis of the capsule is likewise removed by the process of scraping, and constitutes about one-twelfth of the whole product. The opium is now in the form of a glutinous, granular jelly, and is transferred into small earthen vessels, where it is beaten, and at the same time, moistened occasionally with saliva. It is then wrapped in dry leaves for sale. The extraction of the opium from the capsules does not injure the seeds. In different countries, the mode of collecting the opium varies, in some, the incisions are made transversely, but in all, the essential steps are nearly similar. An inspection of the various kinds of opium, would indicate a difference in the mode of extraction, as well as in its subsequent manipu- lations. Sometimes it consists of small tears or drops, which appear to have undergone no other process after collection than agglutination ; again, it is found composed of thin layers, partially inspissated on poppy leaves, and afterward united along with the leaves into roundish masses; and that of Egypt, Hindostan, and Europe is quite homogeneous. The supply of opium, in commerce, is chiefly obtained from Persia, Hindostan, Egypt, and Asiatic Turkey. That from Turkey is the most esteemed, and is the kind principally used in the United States. It is imported direct from Smyrna, or indirectly through various European ports. Turkey opium is prepared in Anatolia; it usually comes to us in more or less flattened masses, of irregular size and shape, covered with leaves, or the remains of leaves and with the reddish capsules of some species of Rumex, which are said to be absent in the inferior kinds. There are several varieties of it, among which we may refer to the Smyrna and Constantinople opium. The Smyrna opium is imported in lumps weighing from half a pound to a pound, and occasionally two or three pounds, and is of various shapes, owing probably to the pres- sure they receive, while yet soft, in the cases which contain them ; some- times they are found in flat cakes. Internally, they are still soft when found in the market; externally they are hard, and covered with the red- dish capsules of a species of Rumex to prevent their surfaces from adhering, and sometimes with the remains of leaves. Their substance is rather pale- brown, and consists of minute agglutinated scales or tears, and are un- doubtedly formed from the juice which escapes in drops from the incisions in the capsules, and is allowed to concrete before collecting them. In the finer kinds, the only impurities present, are fragments of the capsules. This variety of opium is the most abundant in our markets, and is the best opium met with; it is more productive in morphia than any other, yielding Papaver Somniferum. 707 from 9 to 11 per cent. There is an inferior article, or Common Smyrna Opium, of the form and size of the previous kind; it is commonly covered with poppy leaves, and often with rumex capsules; it is harder because older; it has a darker color, sometimes brownish-black inter- nally, at times a musty smell, with more or less moldiness. It is some- times homogeneous, and again appears to be composed of thin layers with interposed poppy leaves. This variety is less productive of mor- phia than the preceding, and is likewise more liable to adulteration. Constantinople Opium is met with in flat, roundish masses, from half a pound to two and a half pounds in weight, and in its exterior appear- ance very much resembles the superior Smyrna variety. It differs, however, in its interior constitution, being for the most part, dry, hard, pale-brown, and homogeneous in texture, or rather composed, as it were, of agglutinated scales, owing, probably, to its being removed from the capsules before concretion, or to its being subsequently subjected to pressure. In point of purity, it is about equal to the Smyrna drug. It is only occasionally met with in commerce. Other varieties, as Egyptian, India, and Persian Opium are occasion- ally met with. The Egyptian variety has been largely imported, but of late is gradually disappearing from our markets. It is in round flat- tened cakes, of various dimensions, weighing from four to eight ounces, and sometimes a pound. It is wrapped up in a poppy leaf, is dry, hard, and brittle, has a pale-brown color and conchoidal, waxy fracture, with an odor weaker than the Smyrna opium. It is always destitute of the Rumex capsules. It is inferior to the Turkey opium, though occasion- ally parcels are met with as rich in morphia, but the quality is by no means uniform. It is probably adulterated in its preparation, and should never be employed in the preparation of tinctures, or for filling the prescriptions of physicians. The India or East India Opium, very seldom reaches our markets; a greater abundance of it is made than of any other kind of opium, and in the East it commands high prices, though inferior to Turkey opium. There are two chief varieties of it, the Bengal, and the Malwah opium. The Bengal Opium is produced in Bahar and Benares ; it is in round balls, weighing three pounds and a half, invested by a coating or case about half an inch thick, and half a pound in weight, formed of tobacco-leaves and agglutinated poppy capsules. Its interior is brownish-black, of the consistence of stiff paste, and has the characteristic odor and taste of opium. This is an inferior opium, yielding about 4 or 5 per cent, of morphia, and is not only subject to adulteration, but is injured, in consequence of the juice being kept until fermentation takes place, before it is made up. Another variety of Bengal Opium, is called Garden Patna Opium; it is pre- pared in Bahar with much care, from juice which has not been allowed to ferment. It is in cakes about three or four inches square, and about half an inch thick, weighing four ounces, and is neatly packed in cases 708 Materia Medica. with a partition of mica between each cake. The cakes are without covering, hard, dry, brittle, of a uniform fracture, light-brown, and sometimes almost black, very much resembling the Egyptian Opium. They are superior to the preceding Bengal Opium, and some specimens are little inferior to average Turkey Opium in their proportion of mor- phia. This opium is never imported as an article of trade. Malwah Opium is in flat, roundish cakes, five or six inches in diameter, and from four to eight ounces in weight. They are commonly quite hard, dry, brittle, almost pulverizable, of a light-brown color, a shining frac- ture, a compact homogeneous texture, free from mechanical impurities, and frequently presenting cracks near their circumference. It is superior to the common Bengal Opium, and is not met with in this country. Persian Opium has occasionally found its way into our markets, but it is very rare. It is in cylindrical sticks five or six inches long, and about half an inch thick, wrapped in glossy paper, and tied with a cotton thread. It is soft and flexible, of uniform consistence, does not harden when kept for years, is of a paler-brown color than any other kind, and its texture, under the microscope, is distinctly granular, as if it were composed of agglutinated tears. It is of inferior quality. But it is not in Asia alone that Opium has been collected; many successful attempts have been made in England and other parts of Europe; and although the culture of the poppy has been limited in these places, yet opium has been prepared fully equal to the Turkey drug, and at a much cheaper rate. Opium, when of good quality, has a strong, very peculiar, narcotic odor, with a most intense and persistent bitter taste, somewhat aromatic and acrid. Its color is deep reddish-brown or deep fawn, its texture compact, and its specific gravity 1.336. The only change that good opium undergoes by keeping, is that of gradually becoming hard; the inferior varieties, are very apt to become moldy after a time. Persons unaccustomed to its use will often have their mouths blistered by chew- ing it, and it is very apt to excite more or less irritation in the lips and tongue. When soft, as it is usually in the center of the mass, it is tena- cious, and on exposure to the air gradually hardens, and ultimately becomes brittle, breaking with a shining fracture, and giving a yellowish- brown powder, when pulverized, which is very apt to cohere. Upon the application of a gentle heat it softens and becomes adhesive, and at a higher temperature it burns, evolving peculiar odorous fumes. Water, cold or warm, dissolves about two-thirds of it, including a great part of its active ingredients, and forms a deep reddish-brown infusion; the residuum consists chiefly of a substance analogous to caoutchouc, with a considerable portion of narcotin. Alcohol dissolves nearly four-fifths of its weight, and the whole of its active parts. Sulphuric ether chiefly dissolves narcotin, which may be obtained in fine crystals on evapora- tion. The concentrated mineral acids disorganize opium; but the Papaver Somniferum. 709 diluted acids, Doth mineral and vegetable, are powerful solvents, and exhaust it entirely of its active principles. Probably, no drug has more engaged the attention of chemists than this; but notwithstanding the many investigations of it, nothing of importance was developed until 1803 when Derosne made known the existence of a crystallizable substance which he had discovered in opium; and which was subsequently termed narcotin; in the year following, Seguin discovered another crystallizable body, but did not fully investi- gate its nature. In 1817 Sertuerner announced the discovery of mor- phia and meconic acid, since which later experimenters have demonstrated that this drug is complex in its composition, containining no less than seventeen or eighteen constituents. It contains morphia, which is its most important principle, narcotin, codeia, paramorphia, narcein, meco- nin, porphyroxin, meconic and sulphuric acids, a peculiar acid not yet fully investigated, extractive matter, gum, bassorin, a peculiar resinous body insoluble in ether and containing nitrogen, fixed oil, a substance resembling caoutchouc, an odorous volatile principle, lignin, a small proportion of acetic acid, sulphate of lime, sulphate of potassa, alumina, and iron, and also what appears to be only an occasional constituent, termed by Pelletier, pseudomorphia, beside papaverina discovered by Dr. G. Merck. Inferior opium has a blackish color, a weak or empyreumatic smell, a sweet or slightly nauseous and bitter taste; a soft, viscid, or greasy con- sistence, and a dull fracture; or it may possess an irregular, heterogeneous texture, arising from foreign impurities. It should not color the saliva deep brown, nor leave a dark uniform trace when drawn over paper, nor form with water a thick viscid solution. When drawn over paper, good opium usually leaves an interrupted trace of a light-brown color. All the substances which cause precipitates with opium do not neces- sarily affect its medical virtues; but those agents which are strictly incompatible, are all vegetable infusions containing tannic or gallic acids, which separate and precipitate its active principle, and also the alkalies or their solutions. Opium is very subject to adulterations, which are practiced before it is imported into this country. Sand, dust, stones, oil, extract of poppy, and various other substances are employed for the purpose. Some of these impurities can be detected by ocular inspection, but others are more difficult to distinguish. Many purchasers rely almost entirely on external characters, as color, odor, taste, texture, moisture, and freedom from mechanical admixtures; but these constitute fallacious criterions. Meconic acid and morphia, have, thus far, been found only in the pro- ducts of the poppy—hence, the presence of these agents will prove the existence of opium in any suspected mass, although it will not determine its quality. Meconic acid may be ascertained by forming an aqueous infusion of the substance to be examined, and adding to it the tincture 710 Materia Medica. of chloride of iron, if the solution become changed to a red color, this acid is probably present. The matter may be rendered more certain by the following process : Add to the filtered infusion an excess of a solu- tion of acetate of lead; if opium be present, there will be a precipitate of meconate of lead, and the acetates of morphia and lead will remain in solution. Suspend the precipitate in water, and decompose it, either by adding a little diluted sulphuric acid, which forms the sulphate of lead, and leaves the meconic acid in solution; or, by passing through it a stream of sulphureted hydrogen, removing the precipitated sulphuret of lead by filtration, and heating the clear liquor so as to drive off the sulphureted hydrogen. If meconic acid be present, the clear liquor thus obtained, will yield a red color with tincture of muriate of iron, a green precipitate with the ammoniated sulphate of copper, and white precipitates soluble in nitric acid, with acetate of lead, nitrate of silver, and chloride of barium. To ascertain the presence of morphia, take the above liquid after the sulphureted hydrogen has been driven off by heat, and apply the following reagents : Nitric acid, colors it red if mor- phia be present; iodic acid, which is decomposed by the morphia with the extrication of iodine, colors the liquid reddish-brown, and, if starch be present, unites with it to form a blue compound; tannic acid, precipi- tates an insoluble tannate of morphia; solution of ammonia, carefully added so as not to be in excess, throws down a precipitate of morphia, soluble in a great excess of that alkali, or of potassa; and if the pre- cipitate afford a deep-red color becoming yellow, with nitric acid, and a blue color with the sesquichloride of iron, the proof is complete. Having now ascertained that opium is present in the mass under examination, the next thing is to ascertain its quality, and this can only be done by extracting its morphia ; the proportion of morphia obtained is the best test of its purity. Good opium should yield at least ten per cent, of morphia, according to the processes named under the head of Morphia, which see. The Edinburgh College gives the following test: "A solu- tion from 100 grains of fine opium macerated twenty-four hours in two fluidounces of water, filtered and strongly squeezed in a cloth, if treated with a cold solution of half an ounce of carbonate of soda in two waters, yields a precipitate which weighs when dry, at least ten grains, and dis- solves entirely in solution of oxalic acid." The following is Guilliermond's test of the quality of opium, as ascer- tained by its amount of morphia: "Take 15 parts of opium, cut in pieces, rub it up with 60 parts of alcohol at 160°, drain the mixture on linen and express, treat the residue with 40 parts of alcohol at the same temperature, unite the tinctures in a vessel with a large mouth into which 4 parts of solution of ammonia (22° Cartier), have been intro- duced, and allow the mixture to stand 12 hours. The crystals which form are to be put upon linen, washed repeatedly with water to separate the meconate of ammonia, and then introduced into a small vessel of Papaver Somniferum. 711 water. The crystals of narcotina being very light, remain suspended in the water, and may be decanted along with it, while those of morphia remaining at the bottom, may be collected and weighed. Good opium treated in this way will yield for the 15 parts employed from 1.25 to 1.75 parts of the crystals of morphia." As these crystals are not quite free from narcotina, M. de Vry proposes the following modification: "The mixture of morphia and narcotina, precipitated from the alcoholic solution by ammonia, after being washed, is to be heated with a slight excess of sulphate of copper dissolved in pure water. The narcotina has no action on the sulphate of copper, which is decomposed by the morphia, producing sulphate of morphia and tribasic sulphate of copper. The latter and the narcotina remain undissolved, and a solution is ob- tained containing sulphate of morphia with a little sulphate of copper. This being filtered is treated first with sulphureted hydrogen, which precipitates the copper, and afterward with ammonia, which throws down the morphia. Morphia and some of its salts are treated of under another head,—see part III, Morphia. Narcotin or Narcotina, is considered alkaline by some who bestow upon it the latter name, and others who view it as a neutral principle, give it the former term. It may be obtained from opium exhausted in water, by macerating it with diluted acetic or pyroligneous acid, filtering the solution and decomposing it with potassa, washing the precipitate with water, and purifying it by solution in boiling alcohol, from which it crystallizes as the liquid cools. Should it still be impure, the solution in alcohol and crystallization may be repeated several times if necessary. Narcotina may likewise be obtained by digesting opium in sulphuric ether, and as the ethereal solution is slowly evaporated, crystals of narcotina are deposited. It is white, tasteless, and inodorous; it crystallizes from alcohol in thin, unequally-beveled pearly tables, but in regular rhombic prisms from ether; is insoluble in cold water, soluble in 400 parts of boiling water, in 100 parts of cold and 24 of boiling alcohol which deposits it upon cooling, soluble in ether, diluted acids, fixed and volatile oils, and insoluble in solution of potassa. At a mode- rate temperature it is fusible, being converted into a resinous-like sub- stance, and when pure it is incapable of forming a yellow solution with nitric acid, or a blue one with sesquichloride of iron. It unites with acids forming definite compounds, some of which are crystallizable, but does not prevent them from reddening litmus paper. Its salts are very bitter, and their solution reddens litmus paper. Narcotina consists of nitrogen, carbon, hydrogen and oxygen; its received formula is NCts H24 O15. Its effects upon the system are but very imperfectly known. One grain dissolved in oil threw a dog into a state of stupor terminating in death in the course of twenty-four hours. Acetic acid is said to modify its action, also nitric and muriatic acids. Twenty-four grains dissolved in vinegar will not destroy a dog; thirty grains similarly dissolved exerted 712 Materia Medica. no influence upon several patients to whom this dose was given. Thirty or forty grains dissolved in acetic or sulphuric acid, or in olive oil, proves fatal to dogs, but not when put in nitric or muriatic acid. It has been highly recommended as an antiperiodic; three grains to be given as a dose, in a solution of muriatic acid, and repeated three times a day; it is said to prove sudorific, and never to occasion distressing headache and restlessness, as is sometimes the case with quinia. Codeia was discovered by Robiquet, in 1832. It exists in opium com- bined with meconic acid, and is extracted with the morphia in the preparation of the muriate. When the liquor containing the mixed muriates of morphia and codeia is treated with ammonia, the morphia is precipitated, and the codeia remains in the liquid, from which it may be obtained by evaporation and crystallization. It may then be purified by dissolving the crystals in hot ether, and evaporating. It may like- wise be separated from morphia by a solution of soda or potassa, which dissolves the morphia and leaves the codeia. Codeia forms in colorless octahedral crystals. It is soluble in alcohol, ether and in water, which takes up 1.26 per cent, at 60°, 3.7 at 110°, and 5.9 at 212°. When added to boiling water in excess, the undissolved portion melts and sinks to the bottom, looking like oil. It melts at 300° without decomposition. It has an alkaline reaction on test-paper, forms salts with the acids, some of which are crystallizable, and does not become changed to a red color with nitric acid, nor to a blue with the salts of sesquioxide of iron. Tannic acid precipitates it from its solutions, forming a tannate of codeia. It consists of nitrogen, carbon, hydrogen, and oxygen, its received formula being NGi5 H20 Oj. In doses of one or two grains, it acts on the nervous system, directing its influence apparently to the great sym- pathetic, relieving painful disorders which seem to have originated from this nerve, but producing no effect upon pains of parts receiving a supply of nerves from the spinal marrow. It does not affect the circulation, disturb digestion, nor cause constipation. The nitrate of codeia in doses of four or six grains acts as an excitant, accelerating the pulse, increas- ing the temperature of the head and face, with itching of the skin, and a species of intoxication, followed after a lapse of several hours, with an unpleasant depression, nausea, and sometimes vomiting. Like nar- cotina its influence upon the system is imperfectly known. Paramorphia was discovered by Pelletier. It is prepared by treating an infusion of opium with milk of lime; the resulting precipitate must be washed with water till the liquid comes away colorless. Then treat with alcohol, which, instead of taking up morphia, yields a new alkaline principle, which may be obtained by evaporating the alcohol, dissolving the residue with ether, and allowing the ethereal solution to evaporate spontaneously. The resulting crystalline mass must, in order to purify it, be dissolved in an acid, precipitated by ammonia, and recrystallized by means of alcohol or ether. Paramorphia is white, crystallizes in Papaver Somniferum. 713 grains from alcohol, and in very oblique prisms from ether, has an acrid, styptic taste, is hardly soluble in water, very soluble in alcohol or ether, fuses at 266°, and combines with acids forming uncrystallizable salts. Alkaline solutions do not dissolve it, but precipitate it from its acid solu- tions. Nitric acid does not redden it, nor the salts of sesquioxide of iron change it to a blue color. It may be distinguished from codeia, by never being in large crystals, by its not forming crystallizable salts with acids, being always precipitated from its acid solutions by ammonia, and by not melting in oily drops. It differs from narcotina, in having shorter crystals which lack the pearl-like appearance of those of that alkali, in tasting differently, in being much more soluble in cold alcohol, and in the action of nitric acid upon it, which converts it into a resinous-like matter before dissolving it, while the same acid instantly dissolves narcotina. The same elements are found in its composition as in the two previous principles; its formula is NC25 Hu 03. The term Thebain has been proposed for it. One grain of it has produced tetanic spasms, and it appears to produce effects analogous to those of strychnia and brucia. Narcein was discovered by Pelletier in 1832. He obtained it by treating an aqueous extract of opium with distilled water, precipitating the morphia by ammonia, concentrating the solution and filtering it, precipitating the meconic acid by baryta water, separating the excess of baryta by carbonate of ammonia, driving off the excess of the ammo- niacal salt by heat, evaporating the liquor to the consistence of syrup, and setting it aside till a pulpy matter formed containing crystals. This pulpy matter he separated and expressed, treated it with alcohol, and concentrated the alcoholic solution. Upon cooling, delicate silky needles of narcein were deposited, which were readily purified by repeated solution and crystallization. Meconin, which often crystallizes with it, may be separated by the agency of ether. Its effects upon the system are not known. Narcein is white, neutral, inodorous, slightly bitter, fusible at 197° F., soluble in 375 parts of cold and 220 of boiling water, soluble in alcohol, and insoluble in ether. Weak acids render it blue, but nitric acid does not redden it, nor the salts of sesquioxide of iron turn it blue. It is dissolved by acids, but does not combine with nor neutralize them. Its formula is NCas H20 O12. Meconin, first observed by M. Dublanc, junior, is obtained by precipi- tating the aqueous infusion of opium with ammonia, washing the preci- pitate with water until the latter passes colorless, mixing the watery fluids, evaporating them to the consistence of molasses, setting them aside for two or three weeks, during which a mass of granular crystals is formed, then decanting the liquid, expressing the mass, and drying it with a gentle heat. The meconin may be separated from the mass by treating it with boiling alcohol of 36° Baume, evaporating so as to obtain crystals, dissolving these in boiling water with animal charcoal, filtering the liquid while hot, and subjecting the crystals which form 714 Materia Medica. upon the cooling of the solution to the action of ether, which dissolves the meconin, and yields it in a state of purity by spontaneous evapora- tion. Meconin is white, crystallizes in hexangular prisms, is neutral in respect to acids, soluble in 265 parts of cold and 18 of boiling water, very soluble in ether, alcohol, and the essential oils, has an acrid taste without bitterness, fuses at 194°, and in this state forms, with chlorine gas, a blood-red fluid, which crystallizes on cooling. It contains no nitrogen, and is volatilizable without change. Gregory gives its formula as Cio Hs Oi. Meconic acid is obtained by macerating opium in water, filtering the infusion, and adding a solution of chloride of calcium, which causes a precipitate of meconate and sulphate of lime. This precipitate havinw been washed with hot water and with alcohol, is treated with dilute muriatic acid at 180°. The meconate of lime is taken up, and as the liquid cools, bimeconate of lime is deposited. This is dissolved in warm concentrated muriatic acid, which deposits pure meconic acid when it cools. It may be freed from coloring matter by neutralizing it with potassa, decomposing the crystallized meconate thus obtained by muri- atic acid, and again crystallizing. It forms in white, brilliant scaly crystals, of an acid taste followed by bitterness, fusible and volatilizable by heat, soluble in four parts of boiling water, also in cold water or alcohol, reddens vegetable blues, and forms salts. Its compounds with the earths and heavy metallic oxides are generally insoluble in water. With the salts of sesquioxide of iron it produces a blood-red color; with a weak solution of ammoniated sulphate of copper it causes a green precipitate; with acetate of lead, nitrate of silver, and chloride of barium, it produces white precipitates, soluble in nitric acid. It has but little action on the system. Its formula is, according to Gregory, Cu HOn, 3 HO = m^, 3 HO. Porphyroxin is neutral, crystallizes in shining needles, is insoluble in water, soluble in alcohol, ether, and weak acids, and is convertible into a beautiful purple-red or rose-colored solution when heated in diluted muriatic acid. It may be obtained by treating powdered opium (pre- viously exhausted by boiling ether, and then made into a pulp by means of water) with carbonate of potassa, agitating it with ether, evaporating the ethereal solution, dissolving the residue in dilute muriatic acid, and precipitating with ammonia. Paramorphia and porphyroxin are thus obtained together. These are to be dissolved in ether, which by spon- taneous evaporation deposits the paramorphia in crystals, and the por- phyroxin in the form of resin. By the cautious use of alcohol, the porphyroxin is separated, and obtained by evaporating the alcoholic solution. Papaverina is prepared by precipitating the aqueous infusion of opium with soda, exhausting the precipitate with alcohol, evaporating the tincture to dryness, treating the residue with a dilute acid, filtering, Papaver Somniferum. 715 precipitating by ammonia, dissolving the precipitate in muriatic acid, mixing with the solution the acetate of soda, and treating the resulting precipitate with boiling ether; on cooling the papaverina is deposited. It crystallizes in needles, is insoluble in water, very sparingly soluble in cold alcohol or ether, more soluble in these liquids when boiling hot, but deposited as they cool. It forms salts with acids which are nearly inso- luble in water. When moistened with concentrated sulphuric acid, its crystals acquire a dark blue color. Its formula is NCw H21 Os. Pseudomorphia is reddened by nitric acid, and strikes a blue color with the salts of sesquioxide of iron, the same as morphia, but it differs from this in not forming salts with the acids, in not decomposing iodic acid, and in not having any poisonous influence upon the system. It forms shining scales, is sparingly soluble in water and weak alcohol, insoluble in absolute alcohol and ether, and is readily dissolved by caustic potassa or soda. Its supposed formula is C27 His NOu. Properties and Uses.— Opium is a stimulant-narcotic, acting under various circumstances as a sedative, antispasmodic, febrifuge, diapho- retic, and an inspissant of the mucous secretions. Topically, it is a direct stimulant and indirect sedative of the nervous, muscular and vascular systems. A medium dose taken while in health, augments the force, fullness, and frequency of the pulse, increases the heat of the skin, gives energy to the muscles, renders the senses more acute, and produces a general excitement of the whole system—the braiu is espe- cially acted upon, the faculties becoming more clear, the ideas brilliant, precise, and under control, the power of application more intense, the conversational energies augmented, and frequently a state of delirium or intoxication is induced. After a time this excitement subsides, leaving a calm, careless, indifferent, pleasurable sensation, with a series of vague, fleeting ideas, which at the end of half an hour or an hour is succeeded by sleep, which continues for six, eight, or ten hours, and is followed by giddiness, languor of the pulse, nausea, headache, tremors, want of appetite, and other symptoms of deranged nervous action. Other effects likewise occur during the period of its influence upon the system, thus— the mucous secretions become suspended, constipation is induced, the cutaneous secretion is increased, the urinary and biliary secretions may be unaffected, or merely inspissated, in consequence of their discharges being impeded. The retention of urine, and constipation, sometimes exist for several days. No injurious consequences will ultimately result from these effects, unless the dose be frequently repeated, so that the natural powers be destroyed by continuous over-excitement. The un- pleasant symptoms following the sleep caused by opium may be removed by lemon-juice, strong coffee, or a cathartic. The effects of opium vary in different persons, and not unfrequently in the same individual under dissimilar circumstances. In some persons the smallest dose will cause nausea, vomiting, and spasm of the stomach; 716 Materia Medica. in others it will occasion feverishness, headache, watchfulness, restless- ness, startling, disagreeable visions, delirium, anxiety, and afterward an aggravated degree of the more familiar subsequent effects of this drug; these phenomena constitute what is called the idiosyncratic action of opium. Though commonly the result of idiosyncracy, yet these symp- toms are often induced in persons with whom opium in general agrees. Dissolved in vinegar or lemon juice, opium acts more pleasantly, and is less liable to produce the above disagreeable consequences. A disagree- able itching or pricking of the skin, occasionally attended with a slight eruption, will be frequently produced by opium, as well as its various preparations. The narcotic power of opium is lessened by certain states of disease, as in the advanced stage of pneumonia, or peritonitis, by profuse hemorrhage, especially uterine, by severe dysentery, delirium- tremens, some varieties of mania, tetanus, and severe pain or spasm of any kind. It is also modified by the conjunction of other remedies; camphor is thought to diminish the chance of its subsequent or idiosyn- cratic effects; and given with ipecacuanha, three or four times the ordi- nary hypnotic dose may be administered without inducing sleep, but with the effect of bringing on sweating with much greater certainty. Through whatever channel opium is introduced into the body—the stomach, rectum, a wound, vein, excoriation, blistered surface, etc.,—its remote action is exerted on the brain. It acts most energetically when it is promptly absorbed ; yet it has not been detected in the blood. When opium, or any of its preparations, is applied freely to a blistered, exco- riated, or inflamed surface, its effects should be attentively watched, for dangerous accidents have occasionally happened in this way. In large doses, opium is a poison, producing death if the proper remedies are not promptly and unremittingly resorted to. The state of excitement and exhilaration, if caused at all, is of short duration, being speedily followed by depression of the circulation, and of the functions of the brain, as manifested by diminution of the frequency of the pulse, loss of muscular strength, slow, soft respiration, flaccidity of the extremi- ties, languor, drowsiness, torpor or coma, pale features, excessively con- tracted pupils, coldness of the limbs, generally retention of urine, and frequently profuse perspiration, together with an almost total insensibility to external impressions. This state ends in death, unless speedily relieved. The remedies are, emetics of mustard and lobelia seed, with strong coffee, stomach pump, external counter-irritation, cold applica- tions to the head and spine, forced exercise, galvanism, and artificial respiration. As soon as the stomach has been properly evacuated by emesis, internal stimulants must be administered, the best of which are brandy and carbonate of ammonia. As soon as consciousness is once fairly restored, an active cathartic, with the continuation of the forced exercise, generally completes the cure. The same toxicological treat- ment should be pursued in case of poisoning by any of its salts of Papaver Somniferum. 717 morphia. Opium is employed internally in form of pill, powder, tincture, or solution. In addition to the laudanum, and paregoric elixir of the pharmacy, other valuable forms of preparation are used, which it may be proper to notice here. Rousseau's Laudanum, is in fact a tincture of the acetate of morphia, and is three times as active as Sydenham's laudanum, though liable to uncertainty; it is made by placing a vessel containing twelve ounces of pure honey, and three pounds of warm water, in a warm place; and so soon as fermentation commences, add four ounces of good opium pre- viously diffused in twelve ounces of water, and let the whole ferment for one month. Pour off the liquor, and evaporate to ten ounces ; filter, and add four and a half ounces of alcohol. Sydenham's Laudanum is prepared by adding to a pint of Spanish wine, a mixture composed of opium two ounces, saffron one ounce, powdered cloves and cinnamon, of each, one drachm. Expose the whole to a sand bath heat for two or three days, and strain. It is double the strength of ordinary laudanum, a fluidrachm being equal to seven and a half grains of opium. The Black, or Quaker's Drop, is an acetic tincture of opium. It is prepared thus: Take half a pound of good opium in slices, an ounce and a half of bruised nutmegs, and half an ounce of saffron, and boil them in four pounds of verjuice, (or good vinegar), and then add a quarter of a pound of sugar, and two tablespoonfuls of yeast. Place the mixture in a warm place to ferment for the space of six weeks. Then decant, filter, and bottle, adding a little sugar to each bottle. It is about three times stronger than ordinary laudanum, and is preferred by many practitioners, on account of its more uniform agreement with the digestive organs. However, the acetate, or citrate of morphia, are much preferable to these tinctures. The special uses of opium are so numerous, that it is impossible to do more here than mention the most important of them. In all febrile and inflammatory diseases, it is given either alone, or in combination with ipecacuanha to produce diaphoresis. As an anodyne-diaphoretic this combination is likewise beneficial in rheumatic, neuralgic, and gouty diseases, in nervous irritability, morbid vigilance, restlessness, diarrhea, and dysentery. As an antispasmodic in asthma, colic, cholera, hysteria, tetanus, spasm of the stomach attending gout, spasm of the ureters in nephritis, and of the biliary ducts during the passage of calculi, in convulsive affections, and dyspepsia. Also to relieve cough, nausea, tenesmus, and strangury. In the suppression of morbid discharges it frequently answers an important indication, and proves very advantage- ous in diarrhea, chronic catarrh, humoral asthma, diabetes, hemor- rhages, especially uterine hemorrhage, etc. Indeed it will be found valuable in all symptoms or forms of disease characterized by pain, wakefulness, inflammation, increased nervous excitability, increased 718 Materia Medica. mucous secretions, or spasmodic action. Its use is contra-indicated where there is a great amount of inflammatory excitement, which should be reduced before venturing its internal administration, or the drug should be modified in its action by combination with ipecacuanha, in cases where there is any doubt as to the sufficiency of the reduction. In inflammation of the brain, strong determination of blood to the head, deficient secretion from inflamed mucous membranes, and generally in constipation, it is also contra-indicated. If the constipation depends upon spasmodic action, it may then be given as an antispasmodic in combination with a laxative. Opium is often eaten by persons until it becomes a habit exceedingly difficult to overcome ; when taken to ex- cess in this manner it may be known by the deadly pale or sallow aspect, with tokens of emaciation, and a gradual loss of the energies and acti- vity of the whole system. The author of a work entitled, " Confessions of an Opium Eater," tells us that he was cured of this soul-destroyino- vice by using the Ammoniated tincture of Valerian as a substitute for his opiate stimulant. Probably any other stimulant would have answered the same purpose. Externally, opium is employed chiefly to subdue pain, and arrest local inflammatory action ; it is applied in the form of lotion, liniment, or plas- ter, and is of service in neuralgia, rheumatism, some forms of cutaneous disease, irritable blistered surfaces, diseased mucous surfaces, and in erysipelatous inflammations. It is likewise added to collyria in ophthal- mic affections, and to injections in gonorrhea. There is much variety of opinion among Eclectics as to the use of this drug as a medicine, some contending against its use, and others in its favor. That it is a useful agent in many diseases, and exerts an influence not possessed by any other one, no person will attempt to deny; neither does it, when given in the proper medicinal doses, leave the seeds of after disease in the sys- tem, as is the case with arsenical, mercurial, and other preparations, which in small doses decompose the constituents of the body; there- fore, although its present results may be disagreeable, yet, as they are not permanent, there is no good reason why we should dispense with an agent so well calculated to lessen the effects of disease upon the human system. When we administer the almost death-like prostrating emetic, lobelia, the energetic, prostrating, and nauseating hydragogue, podo- phyllin, etc., etc., it is too much like prejudice without reason to oppose opium because its effects continue for a few days, or improper doses and carelessness in its use have resulted in death, and which may, in a degree, be said of every active remedy in the Materia Medica. The dried ripe capsules of poppy have properties analogous to opium, but very feeble, and are sometimes used in decoction, emulsion, syrup, or extract, to calm irritation, lessen pain, promote rest, and produce the general effects of opium ; and externally, as an emollient and anodyne application. Parthenium Integrifolium. 719 Dose of opium in pill or powder from one-fourth of a grain to three grains, according to its influence upon the patient, the nature of the complaint, and the purpose to be effected. Sometimes larger quantities are given, as in severe tetanic, or other nervous affections, and in cases of severe pain. The medium dose to ease pain and produce sleep is, one grain. The dose of the tincture is from ten to fifty drops. When it cannot be taken by mouth, as in cases of obstinate vomiting, and in painful nephritic or uterine affections, strangury from blisters, and in dysenteric tenesmus, it may be injected into the rectum with great ad- vantage, being added to a small quantity of water, flaxseed or elm infu- sion, starch water, mucilage of gum Arabic, etc. When thus given the quantity may be twice that administered by the mouth—yet the prac- titioner should be cautious, as some patients are more powerfully influ- enced by it than others.

PARTHENIUM INTEGRIFOLIUM. Cutting Almond. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Necessaria. THE root. Description.—This plant, also known by the name of Nephritic Plant, is indigenous and perennial, with an erect, striate, pubescent stem, from three to six feet in hight. The leaves are alternate, lance-ovate, hispid- scabrous, coarsely dentate-crenate, coriaceous, lower ones petiolate, upper sessile, sometimes clasping; they are from four to twelve inches long, and about half as wide. Radical petioles a foot long. Heads many- flowered, tomentose, corymbed ; ray-flowers five, somewhat ligulate, fertile; disk-flowers tubular, sterile. Involucre hemispherical, five- leaved; scales in two series, outer ovate, dilated, inner orbicular; recep- tacle, minute, conical, chaffy; achenia five, obovate, compressed, cohering with two contiguous paleae. History.—This plant grows in the Middle and Western States, in dry soils, flowering from July to September. The root is the part used. Its growth is singular ; it issues from a head or caudex, at first small, but gradually increases in size, and terminates very abruptly, givin" off other roots of a similar form, each being a distinct root about the size and shape of a radish, but growing horizontally, and sending up stems from near the large ends of the principal roots, which are blackish out- side, and bluish-gray within. Cold water extracts its medicinal virtues. It has not been analyzed. 720 Materia Medica. Properties and Uses.—Diuretic. The root sliced and infused in cold water, and drank in moderate quantities, is useful in suppression of the urine, scalding of the urine, gonorrhea, gravel, and diseases of the kid- neys and bladder generally. It is highly recommended by some prac- titioners in these diseases. Likewise said to be an aromatic-bitter, and stimulant. PETROLEUM. Petroleum. A bituminous fluid, issuing from the earth. History.—Liquids, or readily fusible solids of native inflammable character, are found in various parts of the globe, which evolve, when heated, a peculiar odor, which burn readily leaving a very small carbo- naceous residue, and which are called Bitumens; to this class of sub- stances Petroleum belongs. They are of two kinds, one liquid, called Naphtha, the other solid, termed Asphaltum. Naphtha is a transparent, yellowish-white, ethereal, very mobile, inflammatory, and very light liquid, and is found in abundance in Persia. It consists exclusively of hydrogen and carbon ; and on account of the absence of oxygen in its composition, it may be used for preserving potassium. Dr. Andreosky, of the Russian army, has, it is stated, used it with benefit in Asiatic Cholera, in doses of from ten to twenty drops, given in half a glass of white wine, or in mint water. The artificial naphtha obtained during the formation of coal gas, when rectified becomes as light and limpid as the natural fluid; and in this state is said to dis- solve caoutchouc, the solution having been usefully applied to the purpose of forming several surgical instruments of that material; it has also been employed for giving a thin coating of caoutchouc to cloth or other fabrics, to render them water-proof. They are varnished with the solution on one side, and the varnished surfaces are applied to each other, and made to adhere by powerful pressure. Asphaltum is a solid, black, dry, friable substance, insoluble in alcohol, but soluble in oil of turpentine by the aid of heat, forming an ink or paint. Naphtha and Asphaltum often exist, naturally combined together; when the asphaltum predominates, the viscid substance formed is called Maltha or Mineral Tar; when the naphtha is in the larger pro- portion, the thick fluid produced is termed Petroleum. Petroleum is found principally at Amiano in the Duchy of Parma, at Gabian in France, upon the borders of the Caspian Sea, in the kingdom of Ava, and in Barbadoes, Trinidad, and other West India islands. The wells of petroleum in Ava are said to produce four hundred thou- sand hogsheads annually. The petroleum from Barbadoes is indicated as the officinal variety by the London and Dublin Colleges. In the United States petroleum is found in various localities, the principal of Petroleum. 721 which are on the Kanawha, in Virginia; near Scottsville, in Kentucky; in Western Pennsylvania; on Duck Creek in Ohio; and on the shores of Seneca Lake in New York. That found in the latter locality is usu- ally called in this country Seneca oil, and similar varieties of petroleum from other native sources are known by the same name. Barbadoes Petroleum, sometimes called Barbadoes Tar, as well as that from Trinidad, is of a dusky-greenish brown, or black color, nearly opake, inflammable, of a strong, peculiar, not agreeable, bituminous taste and odor, unctuous to the touch, and having the consistence of very thick cream or molasses. When exposed to the air it gradually hardens to the consistence of pitch. Heat increases its liquidity, but not its thorough mobility; and a higher heat, by distillation, expels naphtha, leaving a solid residue of asphaltum. Alcohol, acids, and alkalies have but little effect upon it; ether dissolves it, the solution becoming green; and the fixed and volatile oils likewise dissolve it. It consists chiefly of carbon and hydrogen, with a little oxygen and nitro- gen. The Rangoon Petroleum has also a dark greenish-brown color, a strong rather fragrant odor, and the consistence of lard in warm weather; when heated to 90° it becomes a very mobile liquid. By distillation it yields a large quantity of naphtha, and afterward a crystalline principle, identical with paraffin. In the naphtha Dr. Gregory subsequently dis- covered eupione. It is, probably, more active than the Barbadoes Petroleum. Properties and Uses.—Petroleum is considered a stimulating antispas- modic and sudorific, and has been recommended as a remedy in various diseases. In diseases of the chest not attended with inflammation it has been reputed beneficial, and is extolled as a vermifuge, especially for tapeworm. For this purpose it may be taken inwardly in the form of emulsion, and applied externally by friction over the abdomen. Schwartz's formula in such cases, was a mixture of one part of petro- leum with one and a half parts of tincture of assafcetida, of which forty drops were given three times a day. Externally, it is employed as a stimulating embrocation in chilblains, chronic rheumatism, affections of the joints, and paralysis. It is likewise beneficial in cutaneous diseases, especially lepra, psoriasis, and other scaly diseases. The dose of Petro- leum is from ten to thirty minims, given in any convenient vehicle. British Oil is composed of eight fluidounces each of Oil of Turpentine, and Oil of Linseed; four fluidounces each of Oil of Amber, Oil of Juniper; three fluidounces of Barbadoes Petroleum, and one fluidounce of American Petroleum or Seneca Oil. Seneca or Rock Oil is lighter colored, of thinner consistence, and less sapid and odorous than the Barbadoes, and probably contains more naphtha; it is considerably used in domestic practice as an external application. 46 722 Materia Medica. PHOSPHORUS. Phosphorus. Preparation.—Phosphorus is made by adding to bone ashes, which consist principally of phosphate of lime, two-thirds their weight of strong sulphuric acid previously diluted with twelve times its weight of water; allow them to digest for twenty-four hours. The sulphuric acid com- bines with the lime, and precipitates as sulphate of lime, while a super- phosphate of lime remains in solution. The whole is strained through a linen cloth to separate the sulphate of lime, and afterward submitted to evaporation, which causes a fresh precipitation of sulphate, requiring to be separated by a new filtration. The filtered solution of superphos- phate is evaporated to a syrupy consistence, and then thoroughly mixed with half its weight of powdered charcoal, so as to form a soft mass, which is dried by being heated to dull redness in an iron pot. The mass, when cool, is quickly transferred to a coated earthenware retort, furnished with an adopter of copper, bent downward at right angles so as to enter a bottle with a large neck containing water which should rise about two lines above the orifice of the adopter. The bottle is closed round the adopter by a cork, which is traversed by a small glass tube, to give exit to the gaseous products. The retort is heated in a furnace, furnished with a dome, in the most gradual manner, so as to occupy about four hours in bringing it to a red heat. Afterward, the heat is pushed vigorously, so long as any phosphorus drops into the water; and this takes place generally for from twenty-four to thirty hours. During this part of the process, the excess of acid in the superphosphate is decomposed; its oxygen combining with the charcoal, and the liberated phosphorus distilling over. A quantity of the materials sufficient to fill a quart retort will yield about a pound of phosphorus. The calcined bones of sheep are generally preferred, as they contain most phosphate of lime, and are more readily acted on by the acid.— U. S. Disp. M. Donovan has offered a process which facilitates the preparation of phosphorus. It is as follows: Take beef or sheep bones as they are found in commerce, with their natural quantity of fatty matter and moisture. Digest them for four hours in a mixture of one part of nitric acid of commerce, and ten parts of water. This dissolves the calcare- ous salts, leaving the soft gelatinous tissues which retain the form of the bones, and which may be washed and employed in the manufacture of glue. The acidulated liquid containing the phosphate and nitrate of lime, is to be treated with an excess of neutral acetate of lead, and the precipitated phosphate of lead washed and dried. It is then put m a covered crucible and heated to redness to condense its volume, which operation requires great care, else the phosphate will lose its pulveru- lent form and fuse, requiring a difficult pulverization. The dense pulverulent phosphate of lead is then intimately mixed with one-sixth Phosphorus. 723 of its weight of charcoal, previously calcined, and afterward distilled in the ordinary manner in large earthen retorts, properly heated. History.—Phosphorus was discovered in 1669 by Brandt, and was at first obtained from putrid urine; in 1769 it was found in bones by Gahn who published a process for obtaining it. It is a semitransparent solid, without taste, but possessing an alliaceous smell. When perfectly pure, it is colorless; but as usually prepared, it is yellowish or reddish- yellow. It is flexible, sectile, and when cut, exhibits a waxy luster. It is insoluble in water, but dissolves sparingly in alcohol and the oils, and more freely in ether. Its sp. gr. is 1.84 and its equivalent number 32. It takes fire at 100°, melts at 108°, and boils at 550°, air being exclud- ed. During its combustion, it combines with the oxygen of the air, and forms phosphoric acid. On account of its great inflammability, it requires to be kept under water. When exposed to the air, it undergoes a slow combustion, emitting white vapors, which are luminous in the dark. It forms with oxygen, hypophosphorus, phosphorus, and phosphoric acids, and the two isomeric varieties of phosphoric acid, called pyrophosphoric, and metaphosphoric. With hydrogen, it forms phosphureted hydrogen and subphosphureted hydrogen. The only medicinal combinations con- taining phosphorus are phosphoric acid and the phosphates of mercury, iron, lime, and soda. Phosphoric acid in a diluted state, and the three latter phosphates are officinal. In contact with chlorine, bromine, or iodine, without the aid of heat, combustion takes place spontaneously, while the phosphorus combines with these metalloids. It occasionally contains arsenic, antimony or sulphur, from which it should be freed. Those who work in phosphorus, as manufacturers of lucifer matches, are liable to necrosis of the jaw-bone, the consequence of periostitis. Properties and Uses.—In small doses, and properly diluted, phosphorus acts as a powerful diffusible stimulant; in large doses, or when given in substance, it acts as a violent irritant poison. Its action is especially directed to the kidneys and genital organs, producing diuresis, and a sex- ual excitement. It is, undoubtedly, an aphrodisiac, and is of much service in the impotence of old and debilitated subjects. It has been recommend- ed in extreme prostration of the vital powers, dropsy, typhus fever, phthi- sis, marasmus, chlorosis, paralysis, amaurosis, mania, etc. It should never be used in substance, but in solution with ether and oil. The following is a good formula : Take of phosphorus, cut in pieces, four parts; sulphuric ether, two hundred parts; mix, and macerate in a darkened bottle, or in a dark place for one month ; then add one hundred parts of oil of cinnamon, or any other oil, and mix thoroughly together. Decant this into blackened ounce vials, and have them well stopped. Dose, is from ten to fifteen drops, every three hours, in some mucilaginous liquid. In the exhibition of phosphorus, great caution is necessary, and its effects must be closely watched. It should never be given in substance as it is apt to cause violent irritation of the stomach. When taken in a 724 Materia Medica. poisonous dose, give an emetic followed by copious draughts of water and magnesia, which arrest its combustion, and neutralize any phosphoric acid which may form. The following, administered in copious draughts, has been recommended as an antidote to phosphorus: Calcined mag- nesia 4 grains; chlorine water 16 grains; distilled water 224 grains; mix. Phosphorus is seldom employed in Eclectic practice. Off. Prep.—Acidum Phosphoricum Dilutum. PHYSALIS VISCOSA. Ground Cherry. Nat. Ord.—Solanacese. Sex. Syst.—Pentandria Monogynia. the berries. Description. — This plant, also called Yellow-henbane, is indigenous, perennial and pubescent, having a herbaceous, decumbent stem, about a foot high, and which is often viscid as well as the whole plant. The branches are somewhat dichotomous and angular. The leaves are very variable, even in the same plant, solitary or in pairs, ovate, or lanceolate- ovate, cordate or acute at base, often obtuse at the apex, repand-toothed or entire, petiolate, from one to four inches in length, and one-half, or two-thirds as broad, or even of equal breadth ; when they occur in pairs, one of them is much smaller. The fiowers are solitary, axillary, pendu- lous ; the corolla is campanulate-rotate, twice as long as the calyx, tube very short, limb obscurely five-lobed, greenish-yellow, with five brownish spots at base inside. The calyx is five-cleft, persistent, enlarged, inflated, angular; stamens five, connivent; anthers opening lengthwise. Fruit a yel- low or orange-colored berry, inclosed in the calyx. There are many vari- eties of this plant, some of which have been unnecessarily divided into spe- cies, as P. Obscura, P. Pubescens, P. Pennsylvanica, and P. Philadelphia. History.—This plant is common in many parts of the country, and is found growing in dry fields, hill-sides, and road-sides, flowering in July and August. Its root is fusiform, white, and bitter, and will probably act as a bitter-tonic; the fruit or berries are slightly acid and edible, with a faint bitterness. Water or proof spirit extracts their properties. Properties and Uses.—Tonic, laxative, and diuretic, said also to be sedative. The juice of the berries, or a strong infusion is reputed very beneficial in suppression of the urine, gravel, and other urinary disorders. Dose of the juice of the berries, one or two ounces. The Physalis Alkekengi, or Winter Cherry, of Europe, with the stem somewhat branching below, the leaves in pairs, entire, acute; flowers white ; calyx of the fruit red or reddish, with acid and somewhat bitter berries, and growing about a foot high, possesses similar properties, and is likewise recommended as a febrifuge. Dessaignes and Chautard have obtained the bitter principle of the Physalis Alkekengi, which they call Physaline, and which has been Phytolacca Decandra. 725 employed with success in intermittent fever. An alcoholic extract of the plant was prepared, which yielded a bitter dark-colored mass ; the bitter principle was taken up by cold water, and was separated either by means of charcoal, from which it was afterward dissolved by alcohol, or by shaking the aqueous solution with chloroform. The bitter principle thus obtained was pulverulent, slightly colored, and very bitter. When pure, physaline is a white powder, with a faint tinge of yellow ; its taste is at first faintly, afterward permanently bitter; it is noncrystalline, softens at 356° or 374°, and then soon decomposes, burning with a smoky flame. It is sparingly soluble in cold water, to which it communicates a bitter taste ; more soluble in hot water, chloroform and alcohol; and sparingly soluble in ether and acids. It is dissolved by ammonia, and remains unaltered after its volatilization; is not precipitated by nitrate of silver and ammonia from the alcoholic solution, but is precipitated by an am- moniacal solution of acetate of lead. They give its formula as C26 H32 O10. The fruit of the physalis contains citric acid. PHYTOLACCA DECANDRA. Poke. Nat. Ord.—Phytolaccacea?. Sex. Syst.—Decandria Decagynia. the root, leaves and berries. Description.—This plant is known by various other names, as Pigeon- berry, Garget, Scoke, Coakum, etc. It is indigenous, with a perennial root of large size, frequently exceeding a man's leg in diameter, usually branched, fleshy, fibrous, whitish within, easily cut or broken, and covered with a very thin brownish bark or cuticle. The stems are annual, about an inch in diameter, and from five to eight feet in hight, round, smooth, and very much branched; when young they are green, and become of a fine deep purple when matured. The leaves are scat- tered, petiolate, ovate-oblong, smooth on both sides, ribbed underneath, entire, acute, and five inches long by two or three in breadth. The flowers are numerous, small, greenish-white, on long pedunculated racemes opposite to the leaves, sometimes erect, and sometimes droop- ing. Peduncles nearly smooth, angular, ascending; pedicels divaricate, sometimes branched, green, white, or purple, having a small linear bract at base, and two others in the middle. Calyx whitish, consisting of five round-ovate, concave, incurved sepals. Stamens ten, somewhat shorter than the sepals, with white, roundish, two-lobed anthers. Ovary green, round, depressed, ten-furrowed. Styles ten, short, recurved. Berries in long clusters, dark-purple, almost black, round, depressed or flattened, marked with ten furrows on the sides. Cells ten; seeds ten, solitary; embryo curved in a ring around the albumen. History.—Poke is a native of the United States, growing in nearly all parts, along fences, in newly cleared spots, uncultivated fields, road-sides, 726 Materia Medica. moist grounds, etc., and flowering from July to September. It is likewise found naturalized in some parts of Northern Africa and Southern Europe. The young shoots are often used for greens, but become cathartic when they have attained any size. The ashes of the stem and leaves contain a large proportion of potassa, at least forty-two per cent., which, in the plant, is in union with an acid resembling the malic; some persons have successfully employed the ashes as a local application to cancer. The officinal parts are the root, leaves, and berries. The root should be gathered late in November, cut into thin trans- verse slices, and dried with a moderate heat; it loses its virtues by keeping, and should, consequently, be replaced by a fresh supply every year. When properly dried, it is in transverse slices, of a light yellow- ish-brown color externally, wrinkled, and presenting on the internal cut surface, numerous concentric rings, formed by the projecting ends of fibers, between which the intervening matter has shrunk in the drying process. In the older roots the structure is firm and almost ligneous, having a yellowish-white color, alternating with darker circular layers. It has no smell, but the taste is mild, and slightly sweetish, followed by a sense of acrimony. Boiling water, or alcohol extracts its active prin- ciples. Analysis has detected in it tannic acid, gum, starch, sugar, resin, fixed oil, lignin, and various inorganic principles. The leaves should be gathered a short time previous to the ripening of the berries. The berries must be collected when they are fully ripened; they contain a succulent pulp, and yield upon pressure a large quantity of a purplish- red juice. They have but little odor, and a nauseous sweetish taste. The coloring principle of the juice is evanescent, and cannot, conse- quently, be applied to the purposes of dyeing. Alkalies turn it yellow, but acids restore it to its original color. The juice contains saccharine matter, and after fermenting, yields alcohol by distillation. Properties and Uses. — Poke is emetic, cathartic, alterative, anti- herpetic, and somewhat narcotic. In doses of from ten to thirty grains it acts both as an emetic and cathartic, but is seldom used for these purposes on account of the slowness of its action, which, when estab- lished, continues for a long time. Narcotic effects as drowsiness, dim- ness of vision, vertigo, etc., frequently attend its action, but very rarely any pain or spasm. Overdoses cause excessive vomiting or purging, great nervous prostration, occasionally convulsions, and sometimes a tingling or prickling sensation over the whole surface. In doses of from one to five grains it acts as an alterative. The root excites the whole glandular system, and has been highly extolled in syphilitic, scrofulous, rheumatic, and cutaneous diseases. The extract of the root is an excel- lent remedy for the removal of those severe pains attending mercurio- syphilitic affections (osteocopus), in which it is more beneficial than opium. The root roasted in hot ashes until soft, and then mashed and applied as a poultice, is unrivaled in felons and tumors of various Picr^ena Excelsa. 727 kinds. It discusses them rapidly, or, if too far advanced, hastens their suppuration. Care must be had in powdering the root, as it sometimes occasions headache, purging, prostration of strength, and all the symp- toms of a severe coryza. A drachm of the pulverized root or leaves, mixed with an ounce of lard has proved beneficial in psora., tinea-capitis, and some other forms of cutaneous disease; when first applied it occa- sions a sense of heat and smarting. The leaves are somewhat purgative, and are used, in some parts of the country, as a dressing to ulcers. A strong decoction of the leaves is of much benefit in hemorrhoids ; injected into the rectum two or three times a day, and a fomentation of the leaves applied to the part, will almost always give relief, and eventually effect a cure. A fluidrachm or two may be taken internally at the same time, and repeated two or three times a day; should any narcotic effects be produced, its use may be omitted for a day or two, and then commenced in smaller doses. The inspissated juice of the leaves has been recommended in indolent ulcers, and as a remedy in cancer; in this last disease, Dr. Bone com- bined it with gunpowder. A saturated tincture of the berries has been successfully employed in chronic rheumatism. It is also recommended in the same diseases as the root. Dose of the powdered root, as an alterative, from one to five grains; of the tincture, one fluidrachm, three or four times a day; as an emetic, twenty to thirty grains of the powder. The Franklin Institute of the city of New York advertise the active principle of poke root under the name of Phytolaccin; said to be a light- brown powder, with a pleasant, mucilaginous taste, soluble in water, and insoluble in alcohol or ether. I am not advised of its mode of preparation. Said likewise to be a most powerful alterative, aperient, and slightly narcotic. Dose from one-fourth of a grain to a grain, three times a day. Off.

Description.—This is the Quassia Excelsa of Linnaeus, and the Sima- ruba Excelsa of Decandolle, and is known by the various names of Lofty Quassia, Bitter-wood, Bitter-ash, etc. It is a tall tree, frequently attain- ing a hight of one hundred feet, with a straight, tapering stem, often ten 728 Materia Medica. feet in circumference. The branches are given off near the top, and with the trunk, are covered with a smooth gray, or ash-colored bark; that of the roots is of a yellowish color. The wood is of a pale-yellow hue, tough, but not very hard, though susceptible of a good polish. The leaves are pinnate, with a naked petiole, and are composed of from four to eight pairs of nearly opposite, elliptical, pointed, entire, smooth leaflets upon short footstalks, with a terminal leaflet. The flowers are in corymbose clusters, numerous, small, of a yellowish-green, some male, and the rest hermaphrodite in the same cluster. The calyx is very small, with five equal, ovate, pointed sepals. The corolla consists of five equal, lanceolate petals, longer than the sepals. The stamens are five, somewhat longer than the petals, pubescent, and supporting roundish anthers. The ovary is ovate, and surmounted by a slender, grooved style, which is trifid at the apex. The fruit is a small black drupe, usually three, sometimes only one or two, attached to the side of a fleshy receptacle. Quassia Amara, or Bitter Quassia, is a small tree or shrub, much branched, and covered with an ash-colored bark. The leaves are alter- nate, and consist of two pairs of leaflets, and a terminal one; they are elliptic-lanceolate, entire, very smooth, two or three inches in length, and of a deep-green color. The common footstalk is narrow, but winged on each side with a leafy membrane, which expands toward the base of each pair of leaflets, where it is also jointed or articulated. The flowers are hermaphrodite and decandrous, have a brilliant scarlet color, and terminate the branches in long spikes, which are secund and bracteate. The bracts are lanceolate, reflexed, and of a pink color. The calyx consists of five small, persistent sepals. The corolla is formed of five lanceolate petals, which are never fully expanded, being twisted in a spiral manner, and opening irregularly; at the base of the corolla is placed the nectary, consisting of five roundish, colored scales. The stamens are ten, slender, longer than the corolla, and bearing simple anthers, attached by their middle so as to be transverse. The ovary is ovate, five-parted, and supports a slender style, longer than the stamens, and terminated by a subulate stigma. The fruit consists of five black drupes, containing a small unilocular nut, and all attached to a fleshy receptacle. History.—The Quassia Amara is a native of Surinam, flowering in November and December, and is cultivated in some of the West India Islands. It was discovered by a negro, named Quassi, who had become celebrated for his success in curing the malignant fevers of that country; he kept his remedy a secret, until a Swede, Mr. Rolander, obtained the knowledge of it, by giving him a valuable consideration for it. The bark, wood, and root of this tree, were formerly officinal, but it is very doubtful whether, at this time, any of these reach our markets. They Picr^ena Excelsa. 729 are all excessively bitter, and the root especially, has proved very efficacious in malignant fevers. The quassia amara, has now become superseded by the following article. Picrcena Excelsa is a native of Jamaica, and some of the other West India Islands, flowering in October and November, and ripening its fruit in December and January. The wood of this tree furnishes the quassia of commerce, and is used as a substitute for the genuine quassia of Surinam. It is imported in large cylindrical billets, several feet in length, of various diameters, occasionally larger than a man's body, and split into quarters, and frequently retaining a slightly adherent, smooth, and brittle bark, of equal virtue with the wood. These are undoubtedly derived from the trunk or branches, and not from the root. The wrood is very tough, close in texture, at first whitish, but by exposure becomes yellower than Surinam quassia; it is inodorous, of a pure, intensely bitter taste, and imparts all its active properties to water and alcohol. The bark is thin, dark-brown, or thick, grayish-brown, wrinkled, and traversed by reticulating lines. Its virtues are owing to a bitter princi- ple discovered by Winckler, called Quassin. Quassin may be obtained by concentrating a decoction of the wood to three-quarters of the weight of the wood employed, agitating it when cold with slaked lime for twenty-four hours, and filtering, which sepa- rates the pectin and other substances. The filtered liquor is then to be evaporated nearly to dryness, and the residuum to be acted on by boiling alcohol of specific gravity 0.835, which dissolves the quassin, and leaves behind gum, salt, nitre, etc. The alcoholic solution must then be eva- porated to dryness, when impure crystals will be obtained. To purify them, dissolve them in the least possible quantity of absolute alcohol, and then add a large proportion of ether, which throws down a brown mass; filter the liquor and evaporate to dryness. This solution in abso- lute alcohol, the addition of ether, etc., must be repeated until the quassin is obtained colorless. As it is not disposed to assume a crystalline form by this process, it may be effected by pouring the alcoholic solution mixed with ether upon a small quantity of distilled water, and allowing it to evaporate spontaneously. Quassin is white, opake, unalterable in the air, inodorous, and intensely bitter; it is freely soluble in alcohol, sparingly so in ether, soluble in two hundred parts of water, but the solubility of which is increased by the addition of acids or alkalies, and is perfectly neuter. When heated, it melts like a resin. Its aqueous solu- tion is not disturbed by iodine, chlorine, corrosive sublimate, solutions of iron, nor acetate of lead, but is precipitated by tannic acid. It con- sists of carbon, hydrogen and oxygen. Properties and Uses.—Quassia is tonic, febrifuge, and anthelmintic. It is used sometimes in remittent and intermittent fevers ; likewise in dyspepsia, debility during convalescence from exhausting diseases, and 730 Materia Medica. for worms. It preserves animal matters from decay, which is a property possessed more or less by all simple bitters. The decoction administered by way of injection, will remove ascarides. An infusion may be made by macerating for twelve hours, an ounce of the rasped or ground quas- sia in a pint of cold water ; the cold water does not dissolve the extrac- tive matter. Of this a wineglass half full may be taken three times a day, either alone, or with some ginger tea, and will be found useful for feeble, emaciated persons, with impaired digestive organs. Or an extract made by evaporating the decoction to a pilular consistence, may be given in doses of one grain, three or four times a day, and which will be found less offensive to the stomach than the infusion or decoction. Quassia, in connection with sulphuric acid, enters largely into the com- position of an Antibacchanalian Elixir, for the cure of drunkenness, and which does certainly destroy all appetite for alcoholic drinks. On flies and other insects quassia acts as a powerful narcotic poison, and the alco- holic extract kills small animals, when introduced into the cellular tissue. Mr. Brande, in his work on chemistry, recommends a strong decoction of quassia, wTell sweetened with brown sugar or molasses, as an effectual poison for flies, and far preferable to the poisonous articles generally used to destroy them. It is certainly worth a trial. Dose of the pow- der, thirty grains; of the infusion, from one to three fluidounces ; of the tincture, one or two fluidrachms ; and of the extract, from two to ten grains. Off.

Description.—Anise has a perennial fusiform woody root, and an erect, branched, solid, round, jointed, striated stem, somewhat rough or downy, and growing about a foot high. The leaves are petiolate ; the lower or radical ones are roundish, cordate, three to five-lobed, unequally toothed, and supported on furrowed, sheath-like petioles ; the middle cauline ones are pinnate-lobed, with cuneate or lanceolate lobes; the upper cauline ones are trifid, undivided, linear. The flowers are small, white, and disposed in flat, terminal umbels, without any involucre. The calyx is very minute or wanting. The corolla consists of five nearly equal, obcordate petals, incurved at tip. The stamens are five, filiform, longer than the petals, with roundish anthers. The ovary is ovate, downy, with long spreading, subulate, capitate styles bearing obtuse stigmas. The fruit is ovate, a line and a half long, dull brown, slightly downy, and not at all shining; the mericarps with five rather prominent ribs, the intervals being rugose. Pinus Palustris. 731 History.—Anise is a native of Egypt, but is extensively cultivated in many parts of Southern Europe. That produced in Spain is smaller than the French or German, and is usually preferred. The fruit, popu- larly called Aniseed is the officinal portion. Aniseed is about a line or a line and a half in length, oval, striated, somewhat downy, attached to their footstalks, of a light greenish-brown color, with a shade of yellow. They have a powerful, penetrating, fragrant odor, and a warm, sweet, aromatic taste. Their virtues depend upon a volatile oil, and are imparted sparingly to water, but freely to alcohol. The volatile oil is officinal; it resides in the envelope of the seeds, and may be readily obtained by distillation with water or spirit. The internal substance of the seeds contains a bland fixed oil, and when they are expressed, a greenish oil is obtained, which consists of a mixture of the fixed and volatile oils. When the seeds are collected before maturity, they are apt to become impaired in quality, by a slight fermentation in the mass. Star-aniseed, which is much used to flavor liquors, being called by the French Badiane, in its sensible properties is similar to the common aniseed ; and the volatile oil upon which its virtues depend, is sold as oil of common anise, and is regarded by some to be much superior. It is derived from an evergreen tree growing in Eastern Asia, called lllicium Anisatum ; the fruit or seeds consist of five or ten brownish ligneous capsules four or five lines in length, united together in the form of a star, each containing a brown shining seed. Properties and Uses.—An aromatic carminative ; used in cases of flatu- lency, flatulent colic of infants, and to remove nausea. Sometimes added to other medicines to improve their flavor, correct griping and other dis- agreeable effects. The dose of aniseed, bruised or powdered, is from twenty to forty grains. Off.

Description.—This tree is also known by the names of Broom Pine, Yellow Pitch-pine, etc., and is the Pinus Australis of Michaux. Its trunk rises to the hight of from sixty to eighty feet, of which distance about forty or fifty feet below the branches has a diameter varying from twelve to twenty inches; the bark of the tree is slightly fur- rowed. The leaves are in threes, of a brilliant green color, about a foot lono-, and united in bunches at the ends of the branches; the sheaths or stipules are pinnatifid, scaly, persistent; buds very long, whitish. Sterile aments violet colored, two inches long. Strobiles or cones 732 Materia Medica. sub-cylindrical, muricate, with small recurved spines, and from eight to ten inches long. Seeds with a thin, white testa. History.—This is a very large indigenous tree, found in the Middle, Southern, and Western States, growing in dry sandy soils. Its timber is strong, compact and durable, and is much used by carpenters and others. From this tree is obtained the greater part of the tar, turpen- tine, resin, etc., used in the United States. The concrete juice is the white turpentine of commerce; it is obtained by making excavations in the trunk during the winter months, about three or four inches from the ground, and of sufficient size to contain three or four pints. About the middle of March the juice begins to flow into these, and continues to flow throughout the warm season, being removed as the excavations become filled ; this is placed in casks, where it slowdy thickens, acquir- ing a soft solid consistence. It is yellowish-white, of a peculiar, some- what aromatic odor, and a warm, pungent, bitterish taste. It is some- what translucent, and of a consistence which varies with the temper- ature ; when exposed to the air it ultimately becomes hard and dry. When recent it affords about seventeen per cent, of essential oil. It is almost wholly soluble in alcohol or ether, and readily unites with the fixed oils. Venice Turpentine is procured from the Larix Europaea, or Abies Larix ; it is a viscid liquid of the consistence of honey, imperfectly trans- parent, yellowish, or slightly greenish in color, having a strong not disa- greeable odor, and a warm, bitterish, and very acrid taste. It is soluble in alcohol, does not readily concrete upon exposure, and is not solidified by one-sixteenth of magnesia. The brown venice turpentine of the shops, is a factitious article said to be made by dissolving resin in oil of turpentine. See Abies Larix. Chian Turpentine is obtained from the Pistachia Terebinthus; it is a thick, tenacious liquid, of a greenish-yellow color, a peculiar penetrating, rather agreeable odor, and a mild taste without bitterness or acrimony. Exposure to the air gradually hardens it. Bordeaux Turpentine is the product of several species of pine, but chiefly the Pinus Sylvestris, and Pinus Maritima. It is whitish, turbid, and thickish, and on standing separates into a transparent liquid fluid, and a fluid of the color and consistence of thickened honey. There are various other turpentines noticed in foreign Materia Medicas, but not being found in this country, it is unnecessary to describe them. All the turpentines have a similarity in taste and odor, yet differing suffi- ciently to characterize each kind. They become thick and eventually solid by exposure, are softened or rendered more liquid by heat, and burn with a white flame and much smoke. Some of them are solidified by the addition of magnesia; alcohol or ether almost completely dissolves them, and they readily unite with the fixed oils by heat. Piper Angustifolium. 733 An adhesive and strengthening plaster may be made as follows: Take of Caoutchouc, reduced to fine shreds, five pounds, steep it in hot water to soften; then remove from the water, dry as quickly as possible, place in a vessel, and cover with oil of turpentine, which must be in- creased in quantity as the caoutchouc absorbs it. When the gum is suf- ficiently dissolved, press it through a fine sieve, and add to it the follow- ing mixtures : 1st. White turpentine, melted and dissolved in a sufficient quantity of oil of turpentine to make it thin enough to strain ; 2d. Capsicum, four ounces, heated in a quart of oil of turpentine, which must be filtered and gradually added and ground with a pound of litharge, and to which Balsam of Peru six ounces, is to be added. This plaster may be spread on paper, linen, or leather.—The phosgene which is used in lamps as a substitute for oil, is said to be composed of, alcohol of 100 per cent., four gallons and a half, oil of turpentine one gallon, camphor two ounces. Burning fluid may he made in two different ways: 1st. Add together alcohol of 90 per cent, ten gallons, oil of pine, one gallon, camphor, four ounces ; or 2d. Alcohol 90 p. c. six gallons, phos- gene, one gallon, oil of turpentine, one pint; mix. Properties and Uses.—The turpentines owe their influence upon the system to their essential oil. The urine is changed to a violet color by their use, and if used too freely, they are apt to occasion strangury, especially when they do not act upon the bowels. White turpentine possesses stimulant, diuretic, and anthelmintic properties, and in large doses it is laxative. Used in gonorrhea, gleet, leucorrhea, chronic diseases of the urinary passages, in chronic catarrhal affections, chronic rheumatism, piles, chronic inflammation or ulceration of the bowels and in chlorosis and amenorrhea. Externally, it is rubefacient and stimu- lant, and enters into various plasters and ointments. Dose, is from a scruple to a drachm, in pill form, or in emulsion with gum arabic, or yelk of egg, loaf sugar, and water. Venice Turpentine, Chian Turpen- tine and Bordeaux Turpentine, possess similar properties, but are seldom used in this country. Off.

Syst.—Diandria Trigynia. THE LEAVES. Description.—This plant is the Artanthe Elongata of Miguel, and the Stephensia Elongata of Kunth; it is described as a shrub with a jointed stem, growing to the hight of about twelve feet. The leaves are sessile 734 Materia Medica. or petiolated very shortly, oval-lanceolate, acuminate, two or three inches long by about one in breadth, bright green on the upper surface, paler and downy beneath, crenate, minutely and strongly reticulated, of an agreeable aromatic odor, and a strong spicy taste. The spikes are solitary, opposite the leaves, and cylindrical. The bracts are pellate or cucullate ; the flowers hermaphrodite. History.—This plant is a native of Peru, and was introduced to the profession by Dr. Ruschenberger, of the U. S. Navy. In the imported drug, the leaves spikes and stalks are mixed together, and more or less compressed in packages. They are easily pulverized, forming a light, greenish, absorbent powder. Water takes up their aroma and a slight pungency, but no astringency. Infusion of galls produces a gray pre- cipitate with infusion of matico ; the sesquichloride of iron causes a deep green one ; tartar-emetic, corrosive sublimate, and gelatin scarcely affect it. They are said to contain chlorophylle, a soft dark-green resin, brown and yellow coloring matters, gum, salts, lignin, a light-green, thickish volatile oil, and a peculiar bitter principle, soluble in water and alcohol, but not in ether, named Maticin; to this and the volatile oil, matico prob- ably owes its activity. Properties and Uses.—Aromatic, tonic, and stimulant, and exerts an influence on the urinary passages. Highly recommended in hemoptysis, hematemesis, dysentery, and hematuria, in doses of one drachm of the powdered leaves, or one or two fluidounces of the infusion, four times a day. The leaves and flowering tops have been used with advantage in diseases of the mucous membrane, as gonorrhea, leucorrhea, menor- rhagia, catarrh of the bladder, hemorrhoids, and epistaxis. Externally, the leaves are used for arresting hemorrhage from wounds, leech-bites, etc.; the downy part of the leaf is said to be the most active part. Also applied to ulcers. A tincture is also used, made with two ounces and a half of the leaves to a pint of diluted alcohol, of which the dose is from one to three fluidrachms. Off. Prep. —Infusum Matico. PIPER CUBEBA. Cubebs. Nat. Ord.—Piperaceaa. Sex. Syst.—Diandria Trigynia. THE BERRIES. Description.—This is a climbing perennial plant, with a smooth, flex- uous, jointed stem; the branches round, about as thick as a goosequill, ash-colored, smooth, rooting at the joints ; when very young minutely downy, as well as the petioles. The leaves are petiolate, oblong or ovate-oblong, entire, acuminate, rounded or obliquely cordate at base, strongly nerved, netted, coriaceous, very smooth, and from four to six Piper Cubeba. 735 and a half inches long by one or two inches broad. The flowers are dicecious and in spikes at the end of the branches, opposite the leaves, on peduncles the length of the petioles. Fruit globose, rather longer than black pepper, on pedicels from four to six lines in length. History.—Piper Cubeba is a native of Java, Prince of Wales, and other East India Islands, where it grows wild in the woods. The dried unripe fruit is the officinal portion ; it is generally imported with the peduncles attached. The fruit or berries are nearly globular, about the size of a small pea, rough, blackish or grayish-brown, of a rather agree- able aromatic odor, and of a hot, bitterish, somewhat camphoraceous taste, leaving a peculiar sensation of coolness in the mouth, similar to that caused by the oil of peppermint. The peduncles or stalks are con- tinuous with raised veins that run over the surface of the berry, and embrace it like a network. The sarcocarp is thin; the shell is hard, almost ligneous, containing within it one loose spherical seed, covered with a blackish coat, but white and oleaginous internally. The powder of cubebs is dark-colored, and of an oily aspect. Cubebs contain a green volatile oil, a ceruminous substance, a yellow volatile oil, a balsa- mic resin, cubebin, chloride of sodium, extractive, and lignin. The volatile oil is officinal. Age deteriorates the properties of cubebs in consequence of the evaporation of their volatile oil ; hence, it is better to keep them whole, pulverizing them when dispensed. Cubebin, was first obtained by Casola; it is a neutral substance, and may be obtained by expressing cubebs from which the oil has been distilled, preparing with them an alcoholic extract, treating this with a solution of potassa, washing the residue with water, and purifying it by repeated crystallizations in alcohol. Thus prepared, it is white, inodo- rous and insipid, not volatilizable by heat, almost insoluble in water, slightly soluble in cold alcohol, freely so in that liquid when hot, and soluble also in acetic acid, ether, and the fixed and volatile oils; although bearing a close resemblance to piperin, it differs from it in containing no nitrogen. Prop>erties and Uses. — Cubebs are mildly stimulant, expectorant, stomachic, and carminative. They act more particularly upon mucous tissues, arresting excessive discharges, especially from the urethra. In large doses they accelerate the circulation, increase the temperature of the system, and occasionally produce headache and giddiness ; with these effects they likewise in most instances, cause an increased flow of urine, to which they impart a peculiar odor. They have been employed successfully in gonorrhea, gleet, and sometimes in leucorrhea, and catarrh of the urinary bladder; if not speedily useful, their use should be discontinued. They are contra-indicated during a high inflammatory condition, and are advised to be used in gonorrhea only when the inflammation is confined to the mucous membrane of the urethra. They 736 Materia Medica. have also been recommended in piles, abscess of the prostate gland, and chronic bronchial inflammation. Their use sometimes occasions nausea or vomiting, and is frequently attended, like copaiba, with an ephemeral synocha, followed by a prompt cessation of the gonorrheal discharge ; in which disease they may be given in powder along with water or milk, or made into a paste with copaiba. The following pre- parations have been successfully used in gonorrhea and gleet;—1. Take of Ethereal extract of Cubebs, Solidified Balsam of Copaiba, and Carbonate of iron, of each, two drachms, Podophyllin half a scruple. Mix, and divide with pills of four grains each, of which one or two mav be given three times a day. 2. Take of pulverized Cubebs, Podophyl- lum, white Pond Lily, of each, half an ounce, Holland gin one pint. Macerate for several days, and give sufficient doses three times a day to act slightly on the bowels. 3. Take of Solidified Copaiba two ounces, Ethereal extract of Cubebs one ounce, Oil of Juniper, a sufficient quan- tity. Mix, and divide into pills of four grains each, of which one or two may be taken three times a day. Dose of Cubebs in powder, from half a drachm to a drachm, three times a day; of the tincture two fluidrachms; of the oil from ten to thirty drops. Off.

Description.—Piper Longum has a wroody, perennial root, with many, creeping, jointed, round stems, downy when young. Branchlets bearing the fruit erect, with the leaves sessile, or nearly so. Leaves on the creeping branches largest, stalked, broad-cordate, seven-nerved; on the erect fruit-bearing branchlets amplexicaul, oblong-cordate, five-nerved ; all smooth, somewhat wrinkled, pale-green below. Stipules of the petioled leaves two, adhering to the petiole, and lanceolate ; of the ses- sile leaves intrapetiolar, single, spathiform. Fertile flowers or catkins in sessile spikes, opposite a leaf, stalked, erect, cylindrical, imbricated with five or more spiral rows of small, orbicular scales. Ovaries sessile, sub-orbicular. Stigma three or four-lobed. Spike of ripe fruit, sub- cylindrical, composed of firmly united one-seeded drupes. Piper Nigrum is a perennial vine with a trailing or climbing stem, round, smooth, shrubby, flexuose, dichotomously branched, jointed, Piper Longum. 737 swelling at the joints, and often throwing out radicles there which adhere to bodies like the roots of ivy, or become roots striking into the ground. The leaves are from four to six inches long, alternate, disti- chous, broad-ovate, acuminate, of a dark-green color, shining above, paler beneath, five to seven-nerved, the nerves connected by lesser transverse ones or veins, and prominent beneath; petioles round, from half an inch to an inch long. The flowers are small, whitish, sessile, in spikes opposite the leaves, mostly toward the extremities of the branches, pedunculate, from three to six inches long, slender, droop- ing, apparently some male, others female, while sometimes the flowers are furnished with both stamens and pistils; stamens three. Fruit ripening irregularly all the year round, sessile, the size of a pea, at first green, then red, and afterward black, covered by pulp. History.—Piper Longum is a native of South-eastern Asia, and is cultivated in Bengal, and many parts of Hindostan. The female spikes, dried in the sun, form the long pepper of the shops. Miguel has separated this plant from the genus Piper and placed it in a new one, Chavica ; he states that the Long Pepper is obtained from three species, viz : Chavica Pepuloides, Chavica Roxburghii, both of which are found in a wild state in India, are cultivated in Bengal, and furnish the Long Pepper of India; and the Chavica Officinarum, a native of the Philip- pine and Sunda Islands, and which yields the Long Pepper of Sumatra and Java. The India Long Pepper is cylindrical, an inch or more in length, indented on its surface, of a dark-gray color, a weak aromatic odor, and a pungent fiery taste, but inferior to black pepper. The Java Long Pep- per is very aromatic, having a pungent aromatic taste stronger than that of black pepper; they are of a grayish-brown, or grayish-cinnamon color, thick, cylindrical, somewhat narrowed toward the apex, thick at base, and faceted with a sort of network, of the projecting apices of the berries; their stalk is roundish, compressed, somewhat woody, curved, and almost smooth. Long-pepper contains a pungent concrete oil or soft resin, aromatic volatile oil, and piperin. Its medical virtues are the same as Black pepper, but it is very little employed in this country, either as a condiment or in medicine. Piper Nigrum is a native of various parts of the East Indies, and is extensively cultivated in Sumatra, Java, Malabar, etc. The plant is propagated by cuttings, and begins to bear fruit in three or four years from the time of planting. The berries are gathered before they are quite ripe, and dried in the sun, when they become black and wrinkled, in consequence of the drying of the pulp over the seed. If permitted to ripen, and macerated in water, so as to permit the removal of the outer coat, they form white pepper, which is less pungent and aromatic than the black pepper. Black pepper is principally imported from Sumatra and Java. The dried berries are about the size of a small pea, 47 738 Materia Medica. roundish, somewhat wrinkled, dark brownish-black externally, whitish internally, with a peculiar, aromatic odor, and a hot, spicy, pungent, bitterish taste. Alcohol or ether extracts their virtues, and water only partially. They contain an acrid concrete oil, or soft resin of a green color, a balsamic volatile oil, a colored gummy substance, an extractive matter precipitated by infusion of galls, bassorin, uric and malic acids, lignin, various salts, and piperin. The activity of black pepper probably depends upon its acrid, green concrete oil, and its volatile oil, which is limpid, colorless, becoming yellow by age, of a strong odor, and an acrid taste, less so, however, than that of the pepper, and consists of ten equivalents of carbon, and eight of hydrogen; with muriatic acid it forms a liquid compound. The concrete oil is soluble in alcohol or ether. Piperin was discovered by Professor GCrsted of Copenhagen, Den- mark. It may be obtained by treating pepper with alcohol, filtering and evaporating the tincture to the consistence of an extract, submitting this extract to the action ^of an alkaline solution by which the oleagi- nous matter is converted into soap, washing the undissolved portion with cold water, filtering, and treating the matter left on the filter with alcohol, and allowing the solution thus obtained to evaporate spontane- ously, or by a gentle heat. Crystals of piperin are deposited and may be purified by alternate solution in alcohol or ether, and crystallization. As ordinarily procured, the crystals of piperin are yellow; when per- fectly pure they are colorless, transparent, inodorous, and nearly taste- less, fusible at 212°, insoluble in cold water, slightly soluble in boiling water, which deposits it on cooling, soluble in alcohol, ether or acetic acid, decomposed by the concentrated mineral acids, becoming of a blood-red color with sulphuric acid, and with the nitric becoming first greenish-yellow, then orange, and finally red. It consists of nitrogen, carbon, hydrogen and oxygen, and its formula, according to Wertheim, is N2 Cro H37 O10. It is supposed to be a neutral substance. Properties and Uses.—Black pepper is a warm carminative stimulant, capable of producing general arterial excitement. Its chief medicinal use is to excite the languid stomach, and correct flatulence, and is some- times added to quinia in cases where the stomach is not susceptible to quinia alone. It has been recommended as a remedy in intermittents, but very often fails. Piperin is occasionally employed in intermittent fever, but will be found less efficient than the alcoholic extract of black pepper. Its use has also been advised in colic, diarrhea, cholera, scarla- tina, chronic gonorrhea, and in solution as a wash for tinea capitis. Piperin should not be administered with astringents, as it is thereby rendered nearly inert. Dose of Black pepper from five to twenty grains; of piperin, from one to eight grains. Off.

Description.—The Lentisk or mastich tree, is a small shrub, seldom more than twelve feet in hight, and eight or ten inches in diameter; it is covered with a smooth, brown bark, and toward the top sends off numerous branches. The leaves are evergreen, petiolate, and abruptly pinnate; the leaflets are from eight to twelve in number, usually alter- nate, with the exception of the two upper which are opposite, oval, lanceolate, entire, obtuse, often mucronate, dark-green above, paler beneath, and sessile upon the common petiole which is winged on each side. The flowers are very small, dicecious, and in single axillary ra- cemes. In the males, the calyx is divided into five minute, ovate seg- ments ; stamens five, very short, with large, brown, and quadrangular anthers. The females are placed alternately on the peduncle, and their calyx consists of three small, scale-like segments. The ovary is ovate, and supports three styles, with reflexed, clavate stigmas. The fruit is a smooth, reddish, obovate drupe, about the size of a small pea, con- taining a smooth nut. History.—This plant is a native of the South of Europe and the Levant; it flowers in April and May. Its wood is hard and yellowish, and is sometimes used in the arts; the kernels of the nut are edible, and furnish an oil which is used in Spain and other places for burning. It is principally cultivated for its resinous juice, known as Mastich, the greater part of which is obtained from the island of Scio. It is obtained by making transverse incisions in the trunk and principal branches, during the month of August; from these the juice slowly exudes, and hardens in tears upon the bark, or drops upon the ground where it is received upon cloths, or upon the bare ground, and concretes in irregular masses. There are two kinds of it in commerce, the Picked Mastich, and Mastich in Sorts. The former is the finest variety; it is in tears of various sizes, oval, roundish, or elongated, frequently flattened, smooth, pale-yellow, translucent, usually covered with a whitish dust from attrition, brittle and easily pulverized, and of a shining fracture. The Mastich in Sorts is a coarser kind, and is composed of many tears agglutinated together, varying in color from pale-yellow, to grayish- brown, and black, together with fragments of wood, bark, and earthy matter intermingled. Mastich has a faint, agreeable, balsamic odor, which is increased by heat or friction; its taste is weak, agreeable, and somewhat terebinthi- nate; when chewed it becomes soft, ductile, whitish-gray, and opake, and after a time slightly acrid. At a moderate heat it melts, and at a higher temperature it burns with a clear flame and balsamic fumes. Its 740 Materia Medica. specific gravity is 1.074. It is insoluble in water, but is wholly soluble in ether, chloroform, and oil of turpentine, and scarcely soluble in the fixed oils. Boiling alcohol dissolves from it a resinous acid, to the amount of nine-tenths of its weight, and leaves a white, ductile sub- stance, somewhat resembling caoutchouc in its properties, and which is soluble in ether, or boiling absolute alcohol. This substance softens and swells up in alcohol, as gluten does in water, and becomes brittle on drying; it is termed Masticin. Mastich consists chiefly of resin, with masticin, and a minute proportion of volatile oil. It is occasionally adulterated with sandarach, olibanum, and other resinous bodies; and in seasons of scarcity with sea-salt. Properties and Uses.—Mastich is seldom employed in medicine. The Turks use it as a masticatory to sweeten the breath and strengthen the gums. It is sometimes employed by dentists to fill the cavities of decayed teeth. The following preparation is recommended for this purpose: Take of pulverized mastich nine parts, sulphuric ether four parts, mix, and digest for several days, strain it through a cloth, and add native alum, in fine powder, a sufficient quantity to form a plastic mass, with which vials holding about two drachms are to be filled, having first poured into each about thirty grains of camphorated alcohol, and fifteen of essence of cloves. This stopping introduced in the cavity of a carious tooth, first well cleansed and dried, is extremely useful on account of the great degree of hardness it acquires. Dissolved in alcohol or oil of tur- pentine mastich forms a brilliant varnish. An ounce of mastich and half a drachm of caoutchouc macerated in four fluidounces of chloroform, and when dissolved, filtered in close vessels, forms a varnish much esteemed by microscopists. PIX LIQUIDA. Tar. History.—The impure turpentine procured by burning from the wood of Pinus Palustris and other species of pinus. It has a peculiar empy- reumatic odor, a bitterish, resinous, somewhat acid taste, a color almost black, and a tenacious consistence between that of a liquid and solid. It is dissolved by alcohol, ether, the fixed and volatile oils, and yields a small proportion of its medicinal virtues to -water. It consists of resinous matter united with acetic acid, oil of turpentine, and various volatile empyreumatic products, and colored with charcoal. By distillation it yields pyroligneous acid, and an empyreumatic oil called Oil of Tar, which contains oil of turpentine, paraffine, eupione, creosote, upon which probably its medicinal virtues depend, picamar, the principle to which its bitter- ness is owing, capnomor, and pittacal. The solid black mass left after the liquid parts have been evaporated, is called Pix Nigra, or Black Pitch; it has a shining fracture, softens, and becomes adhesive with a Plantago Cordata. 741 moderate heat, melts in boiling water, and consists of the unaltered pine-resin, and various empyreumatic resinous products which have received the name of pyretin.— U. S. Disp. Tar is prepared in large quantities in North Carolina and Virginia; and in smaller quantities in New Jersey, New England, and West Pennsylvania, from the Pinus Rigida, or pitch pine. For Burgundy Pitch, Pix Burgundica, see Abies Excelsa; and for Canada Pitch, or gum hemlock, Pix Canadensis, see Abies Canadensis. Properties and Uses.—Similar to those of the turpentines. Used in chronic coughs, chronic bronchial inflammation, ichthyosis, and the vapor has been serviceable in cases of bronchial disease, by being inhaled into the lungs. Externally, in the form of an ointment, it has proved an efficient remedy in tinea capitis, and some cases of psoriasis; also in foul and indolent ulcers. A tar water has been recommended in cough and bronchial affections, prepared as follows: To half a gallon of boil- ing water, add one pint of tar and one pint of honey; stir the mixture, and when cold, strain off the liquid. It is stimulant and diuretic, and may be taken three or four times a day, in doses of a wineglassful. It will also be found beneficial as a wash in some forms of cutaneous disease. Pix Nigra has been used in doses of from ten to sixty drachms in ichthyosis and other cutaneous affections—it may be given in pill form. In piles it has been used with great advantage in the form of the follow- ing ointment: take of pitch, wax, resin, each, ten ounces, olive oil, one pint. Melt them together, and express through linen, and when nearly cool, stir in four ounces of Scotch snuff. Off. Prep.—Emplastrum Picis Compositae; Unguentum Piperis Nigri. PLANTAGO CORDATA. Water Plantain. Nat. Ord.—Plantaginaceae. Sex. Syst.—Tetrandria Monogynia. THE ROOT. Description.—This is an indigenous perennial plant, known likewise as the Heart-leaved Plantain. It is an acaulescent herb, with stout, naked scapes, growing from one to two feet in hight. The leaves are radical, cordate-ovate, broad, smooth, somewhat toothed, thickish, about six inches long, six or eight-ribbed below with a thick midrib, and on long stout petioles. The flowers are small, whitish, somewhat imbricate, the lower ones scattered, and on elongated spikes which are from six to eight inches long; bracts ovate, obtuse. Calyx and corolla lobes, very obtuse. Pyxis a third longer than the calyx, two-celled, with two seeds in each cell. History.—This plant grows in moist places, and along the banks of rivers, from New York and New Jersey to Tennessee; also from Ohio to 742 Materia Medica. Wisconsin, and flowers from April to August. The root is the part used, and yields its properties to water; it has not been analyzed. Properties and Uses. — The root of Plantago Cordata is astringent, anodyne, antispasmodic, and an ti-emetic. The decoction and extract have been successfully used in Asiatic cholera, checking the disease in a short time; they have likewise proved beneficial in dysentery. The plant is certainly deserving more extended investigation. A poultice of the roots is recommended as an application to old, indolent ulcers, bruises, wounds, etc.; it allays inflammation, and reduces swelling. Off.

Description.—This is a perennial acaulescent plant with a round scape from one to three feet in hight, arising from a fibrous root. The leaves are ovate, smoothish, somewhat toothed, five to seven-nerved, each of which contains a strong fiber, which may be pulled out, and abruptly narrowed into a long, channeled petiole. The flowers are white, very small, imbricated, numerous, and are densely disposed on a cylindrical spike from five to twenty inches long. Small plants are frequently found with the spikes only half an inch to two inches long, and the leaves and stalks proportionally small. Stamens and styles long; seeds numerous. History.—Plantain is a well known herb, growing in rich moist places, in fields, by the roadsides, and in grass-plats, and common in Europe and America. It flowers from May to October. The root has a sweet- ish, saline taste, and the leaves are saline, bitterish, and austere. Water or alcohol extracts the virtues of the plant; it has not been analyzed. Properties and Uses. — Plantain is refrigerant, diuretic, astringent, alterative, and antiseptic. The tops and roots in strong decoction, have been highly recommended in syphilitic, mercurial, and scrofulous dis- eases, in the dose of from two to four fluidounces, three or four times a day. It is likewise reputed beneficial in menorrhagia, leucorrhea, hematuria, diarrhea, dysentery, and hemorrhoids. The juice taken internally, in doses of one fluidounce every hour, and also applied to the wound, is in high repute as an antidote to the bites of venomous serpents, spiders, and insects. Externally, the bruised leaves, or an ointment made with them, is useful in wounds, ulcers, ophthalmia, salt- rheum, erysipelas, and some other cutaneous affections. The best form of administration is the juice dissolved in diluted alcohol, and evaporated by gentle heat to the consistence of an extract. Plumbi Acetas. 743 PLUMBI ACETAS. Acetate of Lead. Preparation.—Acetate of Lead is likewise known by the several names of Sugar of Lead, Superacetate of Lead, Saccharum Saturni. It is pre- pared by placing thin lead plates in shallow vessels containing distilled vinegar, or diluted pyroligneous acid, and turning them occasionally so as to bring different portions of the metallic surface in contact with the air. In this way the metal protoxidizes, and a saturated solution of the protoxide is formed, which, by evaporation and crystallization, yields the acetate. This process furnishes a perfectly neutral salt. Another mode consists in dissolving, by the aid of heat, litharge, or the protox- ide of lead obtained by calcination, in an excess of distilled vinegar or of purified pyroligneous acid, contained in leaden boilers. The oxide is rapidly dissolved, and when the acid has become saturated, the solution is transferred to other vessels to cool and crystallize. After the forma- tion of the crystals, the mother-waters are decanted, and by a new evaporation made to yield another crop, which are usually yellow, but may be whitened by repeated solutions and crystallizations. History.—Acetate of lead is extensively manufactured in Germany, Holland, France, England, and in the United States. It is a white salt, crystallizing in transparent, brilliant needles, which have the shape of long prisms, terminated by dihedral summits. It has an acetous odor, and a sweet taste followed by strong astringency. It slowly effloresces when exposed to the air, at the same time parting with a little of its acid. It is soluble both in water and alcohol ; cold water dissolving from one-fourth to three-fifths of its weight. Carbonic acid water, as well as common water, which uniformly contains this acid, produces a slight precipitate of carbonate of lead with the acetate, which interferes with the clearness of the solution; this maybe removed or prevented by the addition of a small portion of vinegar, or of aeetic acid. Acetate of lead ought to dissolve entirely, and form a clear solution, in pure dis- tilled water, free from carbonic acid. Sulphuric acid, or a soluble sul- phate, when added to a solution of the acetate of lead, produces instantly a precipitate of sulphate of lead, the acid disengaging, at the same time, acetic vapors. When heated, the salt fuses in its water of crystalliza- tion ; at a heat of 320° its whole water, with a small proportion of its acid, is speedily discharged, and a heavy white opake mass remains; a higher heat fuses it again, decomposing it, and disengaging acetic acid, and pyro-acetic spirit or acetone ; a still higher temperature leaves a residue of charcoal and reduced lead. In the air-pump vacuum, and with the aid of sulphuric acid or quicklime to absorb water as it escapes, the acetate of lead falls into a white powder, which is completely anhy- drous. Acetate of lead possesses the important property of dissolving 744 Materia Medica. a large quantity of the protoxide of lead. It consists of one equi valent of acetic acid 51, one of protoxide of lead, 111.6, and three of water 27=189.6 ; its formula is (Ci Hs Os+PbO+3HO, or A+ PbO+3Aq.) Acetate of lead is incompatible with all acids, and with those soluble salts formed from them, which produce, with protoxide of lead, insoluble, or sparingly soluble compounds. Acids of this character are the sulphuric, muriatic, citric and tartaric. It is also decomposed by lime-water, and by ammonia, potassa, and soda ; the two last, if added to excess, dis- solving the precipitate at first formed. It is decomposed by hard water, in consequence of the sulphate of lime and common salt which such water usually contains. With sulphureted hydrogen, it gives a black precipitate of sulphuret of lead ; with iodide of potassium, a yellow ore of iodide of lead ; and with carbonate of soda, a white one of carbonate of lead. Properties and Uses.—Acetate of lead in doses of from one to three grains, repeated every two or three hours, is a powerful astringent and sedative ; it is usually given in pill form. In large doses it is an irritant poison ; and in long continued small doses it may induce the peculiar constitutional action of the preparations of lead. Its best antidote is sul- phate of soda, sulphate of magnesia, or phosphate of soda, which should be followed by emetics if necessary, and then by alternate purgatives and opium. Generally an overdose is followed by vomiting, which pre- vents any serious injury, and as long as the bowels are kept regular, its remote constitutional effects are less apt to occur. Large doses, even two hundred and forty grains, have been swallowed, without proving fatal. It is much employed internally among Allopathic practitioners, in hemorrhages from the lungs, intestines, and uterus,—in some forms of diarrhea, and dysentery, — in cholera infantum — in the colliquative diarrhea of phthisis combined with opium — in severe mercurial saliva- tion, and in irritability of the stomach attending certain fevers. It is never used internally by Eclectics, but is occasionally employed externally, in solution, in cases of superficial inflammations, as in ery- thema, erysipelas, spreading inflammation of the subcutaneous cellular tissue, and in many cutaneous diseases. The solution may be made by dissolving a drachm of the salt in five or eight fluidounces of distilled water, to which a fluidrachm of distilled vinegar may be added to prevent the oxide from being thrown down. As a collyrium the usual strength is one or two grains to the ounce of water. In inflammations opium is often conjoined with it, four grains of each being added to every fluid- ounce of water. So much improvement has been recently made in Eclectic practice, that we believe even the external use of this agent can be, in a great measure, dispensed with. Off. Prep.—Lotio Myrrhae Composita. Plumbi Oxidum Rubrum. 745 PLUMBI OXIDUM RUBRUM. Red Oxide of Lead. Preparation.—Red Oxide of Lead, also known by the name of Red- lead, Minium, etc., is prepared on a large scale by the manufacturing chemists. It is obtained from the protoxide of lead, (yellow massicot,) by exposing it, under the access of air, to a temperature just short of what is required to cause fusion, stirring it occasionally for a day and a half or upward, and allowing the product to cool slowly. The French prepare it in tin boxes, closed from the air, and heated nearly to red- ness, and then gradually allowed to cool. Red-lead, to be of good qual- ity, should be made in large quantities at a time, and should be allowed to cool slowly; this is important, for, as the absorption of oxygen, by which it is formed, takes place during a particular interval of temperature only, it is necessary that the heat within that interval should be main- tained sufficiently long to allow all the protoxide to absorb its appro- priate amount of oxygen. History.—Read-lead is a heavy, scaly, tasteless powder, of a bright scarlet color, with a slight tinge of orange. Heat renders it darker, and when raised, fuses it, with the disengagement of oxygen, and its re-con- version into protoxide. Its specific gravity is about 9. It is insoluble in water. Nitrous acid dissolves it entirely, forming nitrate of protoxide of lead; because the excess of oxygen in red-lead converts the nitrous into nitric acid. Diluted nitric acid instantly renders it dark-brown, resolving it into two oxides, one of them the protoxide, which is dis- solved, and the other the peroxide or binoxidc, which remains. It is sometimes adulterated with red oxide of iron, or red-bole, substances which may be detected by dissolving the suspected red-lead in nitric acid, and testing with tincture of galls. This reagent will produce a black precipitate, in consequence of the iron present in the substances mentioned. If powdered brick be present, it will be left undissolved, upon treating the suspected specimen with nitrous acid, which dissolves the lead and leaves the impurity ; or if boiled in water with sugar, and a small quantity of nitric acid, a similar result will take place. When free from impurities, it is completely reduced on charcoal, by means of the blowpipe, into a globule of metallic lead. When treated by nitric acid, it is resolved into protoxide which dissolves, and peroxide which remains insoluble. Chemists differ as to the constitution of red-lead ; it is generally considered to consist of three equivalents of lead and four of oxygen, so united as to constitute it a compound of two equivalents of protoxide, and one of peroxide or plumbic acid (2PbO+Pb02) that is, 223.2 parts of the former oxide, and 119.6 of the latter.

Description.—This plant is also known by the several names of May- apple, Wild-lemon, Raccoon-berry, Wild Mandrake, etc. It is indigenous and herbaceous, with a perennial, smooth, creeping, jointed root, several feet in length, about a quarter of an inch thick, brown externally, yellowish within, and furnished with radicles at the joints. The stem is simple, erect, round, smooth, about a foot in hight, invested at its base by the sheaths which covered it when in bud, and divided at top into two round petioles from three to six inches long; each petiole supports a large, peltate palmate leaf, smooth above, slightly pubescent beneath, deeply divided into five, six, or seven lobes, which are wedge-shaped, two-parted, yellowish-green above, paler below, and irregularly incised at their extremities. In barren stems which support but one leaf, the peltate character is the most perfect. The flower is solitary in the fork of the stem, on a round nodding peduncle one or two inches long, white, large, about two inches in diameter, and somewhat fragrant. The calyx consists of three oval, obtuse, concave, deciduous sepals, which cohere in the bud by their scarious margins. The corolla is composed of from six to nine white, obovate, obtuse, smooth, concave petals, curiously netted with delicate, transparent veins. Stamens from nine to twenty, shorter than the petals, curving upward, with yellow, oblong anthers of twice the length of the filaments, and not opening by perfect uplifted valves. Ovary oval, compressed, obscurely angular. Stigma subses- sile, convex, its surface rendered irregular by numerous folds and con- volutions. The fruit is fleshy, ovoid-oblong, one-celled, one or two inches in length, and crowned with the persistent stigma; its fleshy, mucilaginous pulp, has somewhat the flavor of a strawberry, and contains imbedded in it about twelve ovate seeds, all connected to the lateral receptacle by fibers. When ripe the fruit is of a lemon-yellow color, with round, brownish spots. History.—Mandrake is found in abundance in almost all parts of the United States, in damp and shady woods, and sometimes in dry and exposed situations. It flowers in May and June, and ripens its fruit in September, at which time the leaves wither and fall off. The leaves are said to be poisonous. The fruit has a subacid, sweetish, peculiar taste, Podophyllum Peltatum. 747 is edible, and slightly aperient, and is very much liked by some persons, but extremely disagreeable to others. The root, which is the officinal part, was well known to the Indians before the whites settled the country, and was one of their most active purgatives; it should be collected for medicinal use soon after the ripening of the fruit. The dried root, as found in the shops, is in pieces of various lengths, about two or three lines thick, with broad, swelling, flattened joints at short intervals, longi- tudinally corrugated, blackish-brown, or reddish-brown externally, dirty white internally, and furnished with fibers of a similar color to that of the rhizoma. Its fracture is short and irregular, its odor faint and unpleasant, very similar to ipecacuanha, and its taste is sweetish, bitter, and slightly acrid. Its active principles are readily taken up by alcohol, or ether; water takes up a portion of its activity. Analysis has detected in this root gum, albumen, starch, extractive, lignin, gallic acid, fixed oil, traces of volatile oil, salts of potassa and lime, and two resinous principles, one soluble in alcohol or ether, and the other soluble in alcohol only. Both resins are purgative, and probably compose our medicinal podophyllin. Properties and Uses.—The entire plant in its recent state is an irritant poison, producing vomiting, hypercatharsis, tormina, stupor, and bloating of the body; the root, recently dried, operates as a drastic cathartic and emetic, when given in large doses ; but the violence of its action is materially modified by age, or roasting. Mandrake is cathartic, emetic, alterative, anthelmintic, hydragogue, and sialagogue. It is an active and certain cathartic, being equal, if not superior to jalap, though operating more slowly. When given in combination with bitartrate of potassa, it induces watery stools, on which account it has been found serviceable in dropsical affections. As a deobstruent, it is one of the most valuable in our Materia Medica, acting through and upon all the tissues of the system—and its action continues for a long time. Small doses, repeated at short intervals, to fall short of catharsis, will induce ptyalism with many persons. In bilious and typhoid febrile diseases, it is very valuable as a cathartic, or emeto-cathartic, often breaking up the disease at once. Its cathartic operation is apt to be slow, sometimes remaining twenty-four hours, and producing considerable distress, which is, however, more than compensated for, by the thorough and cleansing manner in which it acts. In chronic hepatitis, there is not its superior in the whole range of medicines, being vastly more useful than mercurial agents, arousing the liver to a healthy action, increasing the flow of bile, and keeping up these actions longer than any other agent with which we are acquainted. In alterative doses, it has been found exceedingly valuable in scrofula, syphilitic diseases, rheumatism, and many other forms of chronic disease. In constipation, it acts upon the bowels, without disposing them to subsequent costiveness. It has likewise been 748 Materia Medica. found very beneficial in dysmenorrhea, amenorrhea, incontinence of urine, worms, and some affections of the bladder. Dose of the powdered root, as a cathartic, from ten to thirty grains; of the tincture, from ten to sixty drops ; as a sialagogue and alterative, from three to ten grains of the powder, or from five to twenty drops of the tincture. Since the preparation of the podophyllin by Mr. W. S. Merrell, the crude drug is seldom employed. The Podophyllum Montanum of Rafinesque, having a slender, deeply furrowed stem, the leaves with sharp, bifid segments, palmate, not peltate, with narrow sinuses, and many unequal teeth ; the petals six to seven, oblong, obtuse ; stamens seven to nine, and berry yellowish oblong, is possessed of similar medical properties.

Preparation.—This is, undoubtedly, as with the major part of our concentrated preparations, an impure resin. It may be prepared by adding a saturated tincture of the root to an equal quantity of water, and distilling off the alcohol; the resin falls to the bottom. The water contains the gum, mucilage, extractive, etc. It may likewise be pre- cipitated without heat by adding a solution of alum to a saturated tincture of the root, but by this process all the resin is not obtained. I am indebted to the Messrs. F. D. Hill & Co., of this city, for the following process of manufacturing podophyllin, as pursued by them; these gentlemen, in common with all true Eclectics, are very desirous of elevating our school of medicine by all honorable means, and one among these means is opposition to all secret remedies or preparations; and for the prompt and cheerful manner in which they have furnished any information requested of them, they deserve the thanks of the pro- fession. " Exhaust coarsely powdered mandrake root with alcohol, by percolation. Place the saturated tincture in a still, and distil off the alcohol, the residue will be a dark fluid of the consistence of molasses; sometimes it is thicker, and when this is the case add a small portion of it to some water, and if it does not form a whitish yellow precipitate, a small quantity of alcohol must be added to it, or enough to cause the light precipitate. Then warm the thick residual fluid, and slowly pour it into three times its volume of cold water, which must be constantly agitated during the process. If poured in too fast, or without agitation the fluid will fall to the bottom unchanged. Allow it to stand for twenty- four hours; at which time nearly all the podophyllin will be precipitated, the addition of a sufficient quantity of muriatic acid will precipitate the remainder. The precipitated podophyllin, of a whitish yellow color, is Podophyllin. 749 now to be removed and placed on a linen filter, and washed several times with water, to remove any remaining acid, gum, etc.; after which it is to be placed in thin layers on paper, and dried in a room of a tem- perature between 65° and 90° F., or if in summer at the natural atmos- pheric temperature—it becomes a shade or two darker by drying in this manner, but if artificial heat be employed to hasten the process, or of a hio-her temperature, the resin becomes quite dark." This valuable agent I had the honor of introducing to the profession several years since. In 1835 I was first led to an examination of the resinous principle of this plant, as well as of the Iris, Cimicifuga, Ale- tris, and several other plants, in consequence of some information given to me by Professor Tully, of Yale College, New Haven, Conn., relative to the resinous constituent of the Cimicifuga Racemosa. And since August, 1835, I have prepared, and used, more or less in my practice, in the treatment of various forms of disease, the resins of Podophyllum, Iris, Cimicifuga, Aletris, and several other medicinal plants. In July, 1844, I first called public attention to the resins of Podophyllum and Iris, in the New York Philosophical Medical Journal, vol. i, No. 7, pages 157-161, in which I recommended the mandrake resin in combi- nation with an alkali, for hepatic diseases, scrofula, dropsy, leucorrhea, syphilis, gonorrhea, gleet, obstructed menstruation, etc., but of which it appears but little notice was taken by the profession. In April, 1846, I again called the attention of the profession to this, as well as many other concentrated preparations, in the Western Medical Reformer, vol. v, No. 12, pages 175-178. Now, as dates are the only reliable source of correct information in such matters, unless some one can show an earlier notice of these articles, and of their practical utility, than the above, their claims will naturally be considered doubtful. The credit of first preparing podophyllin, and other concentrated preparations, for the use of the profession generally, it being part of his avocation, belongs to Mr. W. S. Merrell, druggist and chemist, of Cincinnati, who, first manufactured it in June, 1847; since which it has become an indis- pensable and highly important Eclectic remedy; and is likewise used by many Allopathies and Homoeopathies, and by the former, in all instances where they have employed it, is preferred to mercurials. Podophyllin varies in color according to its mode of precipitation, being when precipitated by heat, dark-brown; and when by acid, a light brownish-yellow, or greenish-olive if by alum. It is insoluble in water, oil of turpentine, dilute nitric acid, and dilute alkalies. It appears to be composed of two resins, both of which are purgative, one is soluble in alcohol only, the other in alcohol, or ether. From the presence of gum, or perhaps from an oxidation of the resin (an example of which may be witnessed in the pine-gum), soon after its preparation, a portion of podophyllin ceases to be dissolved by alcohol. It has no alkaline nor acid reaction, but forms a saponaceous compound with the alkalies. 750 Materia Medica. Properties and Uses.—It possesses the properties of the root in a superior degree; from four to eight grains operate as an active emeto- cathartic, with griping, nausea, prostration, and watery stools; from two to four grains, as a drastic cathartic, with nausea.and griping; from one half a grain to two grains, generally operates as an active cathartic, leaving the bowels in a soluble condition; in very small doses, it is gently aperient and alterative. We make use of this agent in those cases where mercurials are used by a certain class of practitioners, and find the result to be vastly in our favor; it fulfills all the indications for which mercurials are recommended and used. The action of podo- phyllin is very much increased by long trituration, with four or five times its weight of loaf sugar, or sugar of milk (lactin). In doses of half a grain, or a grain, it is one of our most valuable cholagogue cathartics, operating mildly yet effectually, arousing the whole biliary and digestive apparatus to a normal action, and which is very persistent in its character. It likewise exerts a favorable influence on the cuta- neous functions, producing and maintaining a constant moisture on the skin. In doses of from one-eighth to one half of a grain, or rather in sufficient doses not to purge, it acts as a powerful alterative, and will induce ptyalism in some persons, and is very useful in scrofulous and sjrphilitic diseases, hepatic affections, dysmenorrhea, rheumatism, gonor- rhea, and recent disease of the prostate. It produces a powerful and lasting impression upon the glandular system and secretory organs, unequaled by any other article. It has likewise been found to act as an emmenagogue, and may also be safely and beneficially administered in jaundice, dropsies, dysentery, diarrhea, bilious remittent and intermit- tent fevers, puerperal fever, typhoid fever, phrenitis, and all glandular enlargements; and in congestive fever it will produce evacuations from the bowels, when mercurials and all other agents fail. There is not a better cholagogue preparation known in medicine, than the combination of podophyllin and leptandrin. It is superior to mercurials or any other preparation of the kind, has an extensive range of application, combines certainty and permanency of action, and is less liable to effect harm, even in the hands of ignorant or injudicious practitioners, than any other known remedy of equal power and energy. In urethral stricture, and recent disease of the prostate, the following pill has cured several cases: Take of podophyllin and iridin of each four grains, alcoholic extract of belladona, five grains, strychnia, a grain or a grain and a half, conserve of roses a sufficient quantity to make a pill mass. Divide into twenty pills, of which, one may be given for a dose, and repeated three times a day, using in combination with it, active diuretic infusions. Podophyllin should never be given, except in very fine powder, or which is still better, thoroughly triturated with loaf sugar, sugar of milk, ginger, or some soluble extract. Five grains well triturated with sugar of milk, will make ten or fifteen active cathartic doses. When Podophyllin. 751 used alone it is very apt to produce irritation and pain of the stomach, but castile soap, alkalies, or ginger added to it deprives it of most of its irritating and nauseating tendency and disposition to gripe. Caulo- phyllin combined with it, materially lessens its painful and disagreeable effects. Care should always be taken to proportion the dose of podo- phyllin to the susceptibilities and condition of the patient, as in some cases half a grain will prove a vigorous emeto-cathartic, while in others it would require twice that amount. When it operates too actively, the administration of alkaline solutions with aromatics internally, and in severe cases by enema, will check it. Professor R. S. Newton observes, that, "administered in one-fourth or half grain doses, two or three times a day, and continued for several days, it produces an entire change of the secretions throughout the system, especially that of the liver, producing free and copious bilious discharges." He has used it extensively, alone and in combination with leptandrin and cimicifugin. An Eclectic physician says of this resinoid:—"As a cholagogue cathartic, it probably has no equal in the Materia Medica. Its operation is slow, mild and certain. It produces a specific action on the liver, arousing it to action, and producing free 'bilious evacuations,' rather of a hydragogue character, but is not liable to produce intestinal irritation, unless given in unnecessarily large doses. It usually takes from six to eight hours for it to operate as a cathartic, unless combined with cream of tartar, or some other article by which its action will be hastened. As a cathartic in all biliary derangements not attended by intestinal irritation, it is a superior remedy. In bilious fevers, either remittent or intermittent, as well as in acute hepatitis or bilious-pneumonia, it not unfrequently arrests the disease at the first prescription if given in a proper manner, or it so far modifies the attack that the case becomes mild and manageable. In chronic hepatic derangements, with dyspepsia, it is a most, valuable remedy. Its range of application is perhaps more extensive than any other cathartic medicine, except what is claimed by the old school for mercury. The Podophyllin is a regulator of all the secretions as far as any one remedy can be. It is indicated in all cases where according to 'the books,' mercury is indicated, and while in any and every case it will do all the good that mercury can be presumed to do, it is entirely free from any of the objections to that article. The dose varies from one-fourth to one-half a grain, repeated once in two or three hours. The best mode of using it is, to triturate it thoroughly with ten times its weight of pure white sugar, or sugar of milk, and give from one to five grains of the trituration at a dose once in two or three hours," until the proper effect is produced. It will usually operate in about six hours, sometimes in less. If it is desirable to have an operation sooner, add twenty or thirty grains of cream of tartar and one-fourth of a grain of capsicum to each dose. This is not apt to nauseate when first given, 752 Materia Medica. but if the stomach be much deranged or 'bilious,' it will be pretty sure to vomit, though not excessively, about the time its cathartic effect com- mences. If given alone, however, it is quite sure to operate as an emeto-cathartic, unless the doses be very small, and the intervals between them longer than three hours. As an aperient or alterative, from one-sixth to one-fourth of a grain given evening and morning, or three times a day will generally be sufficient. It is better, however, in all cases to triturate it as before directed, and give the dose accordingly. A combination of one part Podophyllin and ten parts Leptandrin tritu- rated with ten parts of sugar, is an excellent alterative in dyspepsia, hepatitis, etc. As a remedy in puerperal fever, I consider the Podo- phyllin almost a specific. I prescribe it in one-fourth to one-half grain doses with half a drachm of cream of tartar, to be repeated every two hours until it produces free purging, and in no instance have I had any trouble with the case after its operation." The late Prof. T. V. Morrow makes the following remarks:—"Per- haps no medicine has been introduced to the notice of the medical profession, for the last one hundred years, which promises to be of so much value as the Podophyllin. An experience somewhat extensive in the use of this agent in the treatment of a great variety of cases of disease, during the last six months, has fully convinced the writer of its immense value as a remedial agent, more especially as a purgative and alterative. To prepare it properly for use, it should be finely pulver- ized, and given in doses of from one and a half to three grains, to an adult, mixed in a little simple syrup or sweetened water—say in one-half a tablespoonful or about two teaspoonfuls. In doses of this size it will operate with great efficiency and certainty as a purgative, in from four to eight hours, producing several pretty copious and moderately consis- tent discharges, which are very frequently charged to a considerable extent with bile. In some instances a longer period will elapse before its operation will commence, and in nearly every case it leaves the bowels in a gently lax condition, perhaps for two or three days after its opera- tion is over. It operates with much energy and efficiency, without harshness, seldom producing griping; but it occasionally produces nausea, and, in full doses, may cause vomiting, but in small doses, seldom produces these effects. Some practitioners, who have used the Podophyllin, say it will operate quite satisfactorily as a purgative, in doses of one grain. This is one of the cathartics which, during its ope- ration, seems to exercise a powerfully controlling influence over the condition of the cutaneous tissue, as well as the action of the heart and arteries, producing, in many instances, a moderately copious perspira- tion, which often continues, to a greater or less extent, during the whole period of its operation. This is more especially true when it causes nausea and vomiting. But when these effects do take place the patients never experience that death-like and powerful depressing sickness, which Podophyllin. 753 not unfrequently results from the operation of the powdered root of the Podophyllum Peltatum, when given in full doses. I have found the Podophyllin quite a popular and convenient purgative, the dose being so remarkably small that no one objects to taking it on account of its unpleasant and inconvenient size. In the treatment of the various kinds of intermittent, remittent, and continued forms of fever, I have had frequent opportunities to test its value, during the past summer and fall. With one single dose, of from two to three grains, of this medicine, I have frequently arrested the progress of a severe attack of bilious remittent fever, requiring nothing further to complete the cure, except some gentle tonic and restorative medicine, and a proper avoidance of the exciting causes. The same remarks apply with equal truth to the intermitting forms of fever, as well as to some of the continued. In every variety of case, which is characterized by much hepatic torpor and congestion of the portal circle, it has manifested a superior controlling power, appearing to arouse the torpid energies of the liver, and restoring very promptly its lost functions. But in no class of cases has this medicine manifested a higher degree of value, so far as I have been able to observe its effects, than in those cases marked by strong determination of blood to the brain, producing either congestion or incipient inflammation of that organ. In several cases of this description, in the treatment of which I have witnessed its effects, I was agreeably surprised to find every trace of congestion eradi- cated by one or two thorough operations of this article. It seemed to exercise a more completely controlling influence over this pathological condition than any medicine I have ever known used for the same pur- pose. Of course, in these cases it was used in moderately full doses, and its operations continued for a considerable length of time. In cases of puerperal fever, in their incipient stage, it has manifested itself as a medicine of superior value, arresting them at once, when administered in full doses, and even as a common purgative dose after confinement, no medicine has exercised a happier influence. I have availed myself of its use under these circumstances, in numerous instances, with the most beneficial and satisfactory results. In a case of dropsy of the serous cavities, as well as cellular texture of the whole body, the Podo- phyllin was administered in doses of one-half a grain, in conjunction with half a teaspoonful of Cremor Tartar, every two hours, until it produced a half dozen or more copious watery discharges from the bowels, and repeated in two or three days afterward, till the same effects took place, it soon relieved the patient completely of the dropsi- cal effusion!! From its effects in this case I should be led to entertain a favorable opinion of its powers in all cases of dropsy. I have used the Podophyllin in numerous cases of cholera infantum, and other attacks of summer-complaint in children, with very satisfac- tory results. In these cases, however, it was given in very small doses. 48 754 Materia Medica. To a child three years old, it was given in doses of from one-fourth to a half of a grain, once in six or eight hours for thirty-six to forty-eight hours, and it scarcely ever failed to afford decided advantage, more especially in those cases in which there was frequent hepatic torpor, in connection with a determination of blood to the head. The results of my experience in the use of this article as a remedial agent, on the whole, are such as to leave no doubt on my mind that it is destined soon to occupy a conspicuous place among the most valuable remedies of the Materia Medica, with a very extended range of application in the treat- ment of disease. As an alterative, it has demonstrated its value beyond all doubt, in numerous cases in which it has been used during the past summer and fall, especially in that class of cases in the treatment of which the routine practitioners of the orthodox school regard the mer- curial preparations as of indispensable importance. Indeed, it promises to be more than a substitute for the mercurials, in all those cases in which these medicines have proved of any substantial value, without their liability to produce injurious effects on the constitution of patients."

Description.—This is an indigenous perennial plant, sometimes known as Blue Bells, Jacob's Ladder, etc. It has a creeping root, and a smooth, erect, weak, fleshy, diffusely-branched stem from twelve to twenty inches high. The leaves are alternate, and pinnately divided; the leaflets from seven to eleven, ovate-lanceolate, acute, subopposite, smooth, entire, sessile, an inch long and half as wide; the upper leaflets are sometimes confluent. The flowers are numerous, terminal, rather large, nodding, on short petioles, blue, and nearly bractless. The calyx is campanulate, five-cleft; the segments lanceolate-acute, persistent, much shorter than the tube of the corolla. The corolla is rotate-campanulate, limb five- lobed, erect, tube short, closed at the base by five stameniferous valves. Stamens five, equally inserted at the summit of the corolla-tube; fila- ments slender, declined, hairy-appendaged at the base; anthers introrse. Capsules three-celled, three-valved; cells two to three-seeded. History.—This is a handsome plant, growing in woods, damp grounds, and along shady river banks, from New York to Wisconsin, bearing blue flowers in May. The root is the part used, and yields its virtues to Polygala Rubella. 755 water; it has not been analyzed. The Polemonium Cceruleum, or Greek- Valerian, is a native of England. It is larger and more numerously- flowered than the above, and is often found cultivated in gardens. The stems are about two feet high, stout, hollow, several from the same root, each dividing at top into a corymbose panicle. The leaves are mostly radical, on long, grooved petioles, pinnately eleven to seventeen foliate; segments sessile, ovate-lanceolate, subopposite, acuminate, oblique, odd one lanceolate. Flowers blue, terminal, suberect. This plant, probably, possesses medicinal virtues similar to the one above. Properties and Uses.—Alterative, diaphoretic, and astringent. A warm infusion of the root will, it is said, produce copious perspiration, and has been found serviceable in pleurisy, febrile and inflammatory diseases. The tincture, made of whisky, in doses of from one to two fluidounces, two or three times a day, has been found valuable in all scrofulous diseases, and other chronic diseases where an alterative is indicated. The infusion is recommended in bites of venomous snakes and insects, and in bowel complaints requiring the use of astringents. Reported to have cured consumption. Off. Prep.—Infusum Polemonii.

It is an indigenous herb, with a perennial, branched, and somewhat fusiform root. The stems are simple, crowded, many from the same root, angular, smooth, and erect, growing from six to twelve feet high. The leaves are linear, oblong, mucronate, smooth, alternate below; linear-lanceo- late, obtuse, sessile above. The flowers are crested, purple, and in terminal or lateral racemes; the former are spike-form, loose, with the flowers perfect and winged; the latter are leafless, prostrate or subterra- neous, wingless, and nearly apetalous. Wing of the calyx broadly obovate, and longer than the crested corolla. Anthers eight, in two equal parcels. Bracts small, subulate, caducous. Lobes of the caruncle two, scale-like, shorter than the seed. History.—This plant is a native of many parts of the United States, usually growing in arid, sandy or gravelly soils, and flowering in July and August. The whole plant is officinal; it is inodorous, with a per- sistent and powerfully bitter taste, which is imparted to water or alcohol. It has not been analyzed. The Polygala Amara and the Polygala Paucifolia, or Fringed Polygala, possess similar properties, and may be employed as substitutes; the root of the latter has a sweet, pungent, aromatic taste, resembling somewhat that of Gaultheria. 756 Materia Medica. Properties and Uses. — In small doses a bitter tonic; in large ones laxative and diaphoretic. An infusion has been found beneficial as a tonic in debility of the digestive organs. It may be used in all cases where a bitter tonic is indicated. POLYGALA SENEGA. Seneka. Nat. Qrd.—Polygalacese. Sex. Syst.—Diadelphia Octandria. the root. Description.—Seneka is an indigenous plant, with a ligneous, contorted, branching and perennial root, which sends up annually several erect, simple, round, somewhat terete, leafy stems, from eight to fourteen inches in hight, brownish-red below, and green above. The leaves are alternate or scattered, nearly or quite sessile, lanceolate, acuminate, bright-green above, paler beneath, with scabrous margins, from one to three inches long, and about one-third as wide. The flowers are small, white, slightly crested, on very small pedicels, and arranged in a some- what dense, terminal, spike-form, filiform raceme, from one to three inches in length. The calyx is five-leaved, with two leaflets wing- shaped, larger than the petals, round-obovate, concave, white, and slightly veined. The corolla is small, closed, having two obtuse lateral segments, and a short-crested extremity. The style is short, somewhat rostrate. The capsules are small, obcordate, invested by the persistent calyx, compressed, two-celled, two-valved. Seeds two, oblong-ovate, acute at one end, slightly hairy, curved, blackish, with a longitudinal, bifid, white strophiola on the concave side. The spike opens slowly, so that the lower flowers are in fruit while the upper ones are in blossom. History.—Seneka, or Seneca, Snake-root, as it is usually called, is found in various parts of the United States in woods, and on hill-sides, flower- ing from June to August. It is found in the greatest abundance in the Southern and Western States, and is rare in the Eastern. The dried root, which is the officinal part, is of various sizes, being from two to five or six lines in diameter ; it presents a tuberous head, with the remains of the stems, below which is the tapering, branched, twisted root, often surrounded by ringed protuberances, and carinated along its whole length. The epidermis is corrugated, transversely cracked, of a yellowish-brown color in the young roots, and brownish-gray in the old; the cortical portion is thick, hard, and resinous, and contains the active principles of the root; the central part is ligneous, white, inert, and should be rejected in the preparation of the powder. When fresh, it has a strong, peculiar, nauseous odor, which is scarcely perceptible in the dried root; its taste is at first mucilaginous and somewhat sweetish, followed by pungency, acridity, irritation of the fauces, and a flow of saliva. It imparts its Polygala Senega. 757 virtues to water or alcohol; diluted alcohol is its best solvent. The infusion is stronger than the decoction, and should be prepared by dis- placement in water not exceeding 104° F. in temperature. Too high a temperature renders a portion of the acrid principle insoluble in water, by causing it to unite with the coloring matter and coagulated albumen of the root. It has been analyzed by several chemists, and with vari- able results; according to the most recent investigations by M. Quevenne, it contains a peculiar acrid principle, named Polygalic Acid; a bitter, yellow coloring matter, nearly insoluble in water, but soluble in ether or alcohol; a volatile principle, named Virgineic Acid; pectic acid or pectin; tannic acid of that variety which precipitates iron green; gum; albu- men ; cerin ; fixed oil; woody fiber; and various saline and earthy substances. The polygalic acid has been variously called Polygalin and Senegin; it contains no azote; is closely analogous to saponin, and is probably the active principle of the root. It may be obtained by the following process of Quevenne: Exhaust powdered seneka by alcohol of 33°, and distil off sufficient alcohol from the tincture to reduce it to the consistence of syrup; treat this with ether to remove the fatty mat- ter, and allow the liquid to stand. It deposits a precipitate which is separated by filtration, and is then mixed with water. To the turbid solution thus formed alcohol is added, which facilitates the production of a white precipitate, consisting chiefly of polygalic acid. The liquid is allowed to stand for several days that the precipitate may be fully formed. The supernatant liquid being decanted, the precipitate is drained upon a filter, and being removed while yet moist, is dissolved by the aid of heat in alcohol of 36°. The solution is boiled with puri- fied animal charcoal, and filtered while hot. Upon cooling it deposits pure polygalic acid. It is a white inodorous powder, of a slight taste at first, but soon followed by pungency, acridity, and pain in the fauces. It is permanent, unalterable in the air, inflammable, slowly soluble in cold, but rapidly so in hot water, soluble in boiling absolute alcohol, which deposits it on cooling, insoluble in ether, the fixed and volatile oils, neutralizes the alkalies, and reddens litmus paper. It consists of carbon, hydrogen, and oxygen. The Polygala Sanguinea, or Caducous Polygala, and the Polygala Chamcebuxus, possess similar properties with the Seneka, and may be used as a substitute. Properties and Uses.—In large doses, seneka is emetic and cathartic; in ordinary doses it stimulates most of the secretions, acting especially as a sialagogue, expectorant, diuretic, diaphoretic, and emmenagogue. It is chiefly employed on account of its expectorant virtues, and is much used in chronic catarrh, and protracted pneumonia, also in humoral asthma, and in the secondary stages of croup. In active inflammation its use is contra-indicated. In relaxed sore-throat it is recommended as 758 Materia Medica. a local stimulant; also as a diaphoretico-diuretic in rheumatism, and as an emmenagogue in amenorrhea. Dose of the powdered root, from ten to twenty grains ; of the infusion or syrup, from half a fluidounce to two fluidounces. The extract prepared from an infusion of the root, obtained by percolation, and evaporated to the proper consistence by means of a water-bath, may be given in doses of from one to three grains. Poly- galic acid may be given for the same purposes as the root, in doses of from one-fourth to one-half of a grain, dissolved in hot water, with the addition of gum and sugar. Off.

Description. —This plant, sometimes called Smart-weed, is the Poly- gonum Hydropiper of Michaux. It is an annual plant, with a smooth stem, branched, often decumbent at base, slender, jointed, swelling above the joints, of a reddish or greenish-brown color, sprinkled with glandu- lar dots, and from one to two feet in hight. The root is white, whorled, and fibrous. The leaves are alternate, lanceolate, petiolate, punctate with pellucid dots, wavy and scabrous on the margin, two or three inches long, and not more than one-fifth as wide ; the petioles are sheath- ing, inflated, fringed. The flowers are small, greenish-white or purple, and are disposed in slender, loose, interrupted, drooping, but finally erect spikes or racemes ; bracts remotely alternate. The calyx is four or five cleft, and covered with glandular dots. Stamens six to eight; styles two to three, united at the base and half way up. Fruit either lenticular or three-sided, opake, roughish. Seed one. History.—Polygonum Punctatum, is a well known, intensely acrid plant, found growing in nearly all parts of the United States in ditches, low grounds, among rubbish, and about brooks and water-courses, flow- ering in August and September. There are many species of Polygonum, but which, although possessing similar virtues, yet differ materially in their medical potency. The whole plant is officinal, and has a biting, pungent, acrid taste, and imparts its virtues to alcohol or water. Age renders it inert, and heat impairs its medical qualities. It should be collected and made into a tincture while fresh. The plant has not been analyzed. The Polygonum Persicaria, called Ladies' Thumb, or Spotted Knot- weed, possesses similar but inferior medicinal properties, and may be dis- tinguished from the above by the deeper green or purplish color of the Polygonum Punctatum. 759 whole plant, a brownish, heart-shaped spot near the center of the leaf, and its rose-colored flowers, in short, dense, terminal spikes. It has a feebly astringent saline taste, and at one time was considered antiseptic. Properties and Uses.—Water-pepper is stimulant, diuretic, emmena- gogue, antiseptic, diaphoretic and vesicant. Highly recommended in amenorrhea, in doses of one fluidrachm of the saturated tincture, two or three times a day, or from four to six grains of the extract. The infu- sion in cold water has been found serviceable in gravel, colds and coughs, and mixed with wheat-bran in bowel complaints. In Asiatic cholera, the patients wrapped in a sheet moistened with a hot decoction, are said to have been much benefited, and recovered. In combination with sul- phate of iron and gum myrrh, it is said to have cured epilepsy—proba- bly dependent on some uterine derangement. Externally, used as fomen- tation, in gangrene, simmered in water and vinegar; the infusion or a fomentation of the leaves has been beneficially applied in chronic ulcers, and hemorrhoidal tumors, also as a wash in chronic erysipelatous inflam- mations, as a fomentation in tympanitis and flatulent colic. The fresh leaves bruised with the leaves of Mayweed, and moistenedj with oil of turpentine, and applied to the skin, will speedily vesicate. The ashes of the plant combined with the ashes of the garden Thyme, Thymus Vul- garis, are, it is said, used by many empirics as a solvent for gravel and stone, injected, in solution, into the bladder: hazardous and doubtful treatment. The infusion in cold water, forms an excellent local application in the sore-mouth of nursing women, and in mercurial salivation. The decoction, or infusion in hot water, is not so active as when prepared in cold or warm water. Dose of the infusion, from two to four fluidounces; of the saturated tincture, from one to four fluidrachms three or four times a day — it is said to cause a warmth and peculiar tingling sensation throughout the system, with slight aching pains in the hips and loins, and a sense of weight and tension within the pelvis. The Polygonum Arifolium, Sickle-Grass, Halbert-lmved Tear-thumb, or Hastate Knot Grass, has a grooved, angled, prostrate, aculeate stem, with reversed prickles, and growing from two to four feet in length. The leaves are halbert-shaped, taper-pointed, long-petioled, from two to four inches long, and about one-half as wide ; the petioles are from half an inch to an inch long. The flowers are few, distinct, reddish-white, and are disposed in loose, slender, terminal, racemose clusters ; peduncles glandular-bristly; calyx often four-parted, closed; stamens six ; styles two, very short; fruit lenticular, large. It grows in low and wet grounds throughout the United States, flowering from June to September. An infusion of this plant in cold water is a powerful diuretic, useful in gravel, strangury, gonorrhea, and all urinary affections; it must be drank freely. Polygonum Fagopyrum, or common Buckwheat, may be used as fol- lows to recall the flow of milk in the breasts of nurses, where it has 760 Materia Medica. disappeared for several days : Stir in any quantity of buckwheat flower, a sufficient quantity of buttermilk to form a poultice; warm it, but be careful not to boil or make it hot. Apply it thus warm, over the whole breast and renew it every four or six hours. Sometimes it requires to be thus used for three or four days before its effects are produced; usually, however, twenty-four hours are sufficient. Off.

Description.—This plant is also known by the names of Rock-Polypod, Fern-root, Rock-Brake, Brake-root, Female-Fern, etc. It has a peren- nial, creeping, irregular, brown root, with membranous scales extending to the caudex or base of the stipe. The fronds are from six to twelve inches high, distiched, green, smooth, deeply pinnatifid, being divided into alternate segments nearly to the midvein, which are linear-oblong, obtuse, crenulate, the upper ones gradually smaller, parallel, a little curved, and about a quarter of an inch wide. Stipe naked and smooth. The fruit on the lower surface of the frond, in large, distinct, golden dots, sori, or capsules, without any indusium, round, in a double row, and becoming finally brownish. History.—Polypody is common on shady rocks, in woods, and moun- tains, throughout the United States. The root and tops are used in medicine ; the root is rather long, about as thick as a goosequill, some- what contorted, covered with brown, easily separable scales, furnished with slender radicles, and marked by numerous small tubercles ; its color is reddish-brown with a tinge of yellow, its odor disagreeably oleagi- nous, and its taste peculiar, sweetish, mucilaginous, somewhat bitter and nauseous. Water extracts its properties. Properties and Uses.—This plant is pectoral, demulcent, purgative, and anthelmintic. A decoction or syrup has been found very valuable in pulmonary and hepatic diseases; and a strong decoction is recom- mended as a purgative, and for the expulsion of taenia, and other worms. Dose of the powdered plant from one to four drachms; of the decoction or syrup, from one to four fluidounces, three or four times a day. Off. Prep.—Decoctum Polypodii.

Description.—This plant, sometimes known as Bear's Bed, Ground Moss, Robin's-Rye, etc., is indigenous, and perennial, with a simple or divided stem, more generally simple, slender, of a reddish color, and from four to seven inches in hight. The leaves are linear-lanceolate, awn- pointed, entire, flattish, appressed, somewhat spreading, the margins inflexed. The capsule is oblong four-sided, the angles acute ; the calyp- tra is densely hairy and white ; the lid or operculum short-beaked from a convex base; apophysis depressed, and discoidal. Peristome single, of sixty-four teeth, adherent by their summits to the membranous-dilated apex of the columella. Inflorescence dicecious ; sterile flowers terminal, cup-shaped. History.—This is an evergreen plant, found on high, dry places, along the margins of dry woods, and exposed places, mostly on a poor, sandy soil, and is of a darker green color than the mosses in general. The leaves are closely set on the stem about one half its length, above which the stem is naked, terminating in a capsule, covered with a white, hairy hood or calyptre. The whole plant is officinal. It yields its properties to boiling water by infusion. It has not been analyzed, but is deserving the especial attention of medical men. Properties and Uses.—This is a very valuable and important Eclectic agent, which has been in use for a number of years, and is, I believe, unknown to any other class of practitioners. It is a powerful diuretic in strong infusions In doses of two fluidounces of the infusion, every half hour, it has been known to remove from a dropsical patient from twenty to forty pounds of water in the space of twenty-four hours. It possesses but very little smell or taste, and never produces any nausea or disa- greeable sensation in the stomach. It may be used in connection with hydragogue cathartics, or even alone, in dropsies, with the most decided advantage ; and is a very useful article in gravel, and all urinary obstruc- tions. Professor Jones considers it worthy to be ranked among the first, if not at the head, of the class of diuretics. Off. Prep.—Infusum Polytrichi. POPULUS BALSAMIFERA. Balsam Poplar. Nat. Ord.—Salicaceas. Sex. Syst.—Dicecia Octandria. the buds. Description.—This tree, also called Tacamahac, or Tacamahac Poplar, attains the hight of from fifty to seventy feet, with a trunk about eighteen 762 Materia Medica. inches in diameter. The branches are smooth, round, deep-brown; the buds acuminate, smooth, and covered in the spring with an abund- ance of fragrant, viscid, balsamic juice. The leaves are ovate, gradually tapering and pointed, smooth on both sides, with fine glandular serra- tures, deep-green above, whitish and reticulate-veined beneath, and on long petioles ; sometimes two glands at the apex of the petiole. Scales dilated, slightly hairy. History.— This tree is found in Canada, the northern parts of the United States, and in Siberia. In this country it is in blossom in April. The leaf-buds are the officinal part, and should be collected in the spring; they have a peculiar, agreeable, balsamic odor, and a,bitterish, balsamic, somewhat pungent taste. The balsamic juice is collected in Canada in shells, and sent to Europe, under the name of Tacamahaca. Alcohol or spirits is the proper solvent. They have not been analyzed. The buds of the Populus Candicans, or Balm of Gilead, possess similar virtues with the above. The tree is of less stature than the P. Balsamifera, the leaves are broader, and heart-shaped, with a distinct sinus at the base—the petioles are hairy and the branches terete. Properties and Uses.—Poplar buds are reputed stimulant, tonic, diu- retic, and antiscorbutic. A tincture of them has been beneficially employed in pectoral, rheumatic, scorbutic, and nephritic affections. Externally, macerated in oil or lard, they form an excellent liniment or ointment in the treatment of wounds, bruises, tumors, some cutaneous diseases, and in local rheumatism. The bark is said to be tonic and cathartic, and to have proved of service in gout and rheumatism. Dose of a tincture of the buds, from one to four fluidrachms ; and is excellent for colds, and pain in the breast. POPULUS TREMULOIDES. American Poplar. Nat. Ord.—Salicaceae. Sex.

Description.—This tree, also known by the names of White-Poplar, and Aspen, attains the hight of from twenty to fifty feet, with a diame- ter of from eight to twelve inches. It is covered with a smooth, green- ish-white bark, except on the trunks of very old trees. The leaves are orbicular-cordate, abruptly acuminate, dentate-serrate, smooth on both sides, pubescent at the margins, dark-green, three-nerved, from two to two and a half inches long, and one and a fourth as wide, and are on long, slender, and laterally compressed petioles, which accounts for the continual agitation of the leaves by the slightest breeze. Aments plumed with silken hairs, about two inches long, pendulous, appearing in April, Potassium. 763 long before the leaves. Scales cut into three or four deep linear divi- sions, and fringed with long hairs. History.—This tree is common in Lower Canada, and in the Northern and Middle States. The bark is the officinal part, and should be col- lected in the spring, just as the sap begins to rise. Its virtues are imparted to alcohol, water, or acetic acid. There are several varieties of this tree, all of which possess similar properties, as the Populus Grandidentata, P. Candicans, etc. These trees owe their virtues to two alkaloids, Populin and Salicin. The process for obtaining Salicin is described under its appropriate head. Populin may be obtained from the solution, after the salicin has been procured, by saturating the excess of sulphuric acid, when the salicin has ceased to crystallize, with a concentrated solution of carbonate of potassa. This precipitates the populin, which should be pressed between folds of blotting paper, and re-dissolved in boiling water; when, upon the cooling of the liquid, the populin will be deposited in the crystalline state. It is very light, purely white, and of a bitter-sweetish taste. When heated, it melts into a colorless and transparent liquid. It is soluble in two thousand parts of cold, and about seventy of boiling water, and in boiling alcohol, acetic acid, or the dilute mineral acids from which alkalies precipitate it unchanged. Properties and Uses.—Poplar bark is tonic and febrifuge, and has been used in intermittent fever with advantage. An infusion of it is reputed a valuable remedy in debility, emaciation, want of appetite, feeble diges- tion, faintness at the stomach, chronic diarrhea, and worms. It is said to possess active diuretic properties, and has been beneficially employed in gonorrhea, gleet, strangury, and other diseases of the urinary organs. The large aspen, P. Grandidentata, is said to be the most active and bitter. Dose of the powdered bark, one drachm, two or three times a day. POTASSIUM. Potassium. Preparation.—A mixture of carbonate of potassa with finely divided charcoal is first prepared by igniting cream of tartar in a covered cruci- ble, which leaves a mixture, well known as the Black Flux. This, while still warm, is mixed with a considerable proportion of charcoal in coarse powder and small fragments recently ignited, and allowed to cool in a covered crucible. The whole is now introduced into one of the hammered iron bottles used for holding mercury, coated outside with a mixture of sand and clay. The bottle is placed horizontally in a wind furnace, and a short wide tube of iron is fitted to it, to which tube is attached a copper receiver, partly filled with good naphtha, and having a diaphragm of copper, and on the further side of the receiver an aperture for the escape of gas, opposite the tube of the bottle; so that, if 764 Materia Medica. necessary, a strong steel rod may be introduced through this aperture, and another in the upper part of the diaphragm into the tube, for the purpose of cleaning it out as it is apt to become choked. The receiver with the naphtha being surrounded with ice, a steady and uniform strong red or white heat (by means of dry wood, the flame of which plays all round the bottle,) is applied to the bottle, and after a time potassium, which is known by the appearance of its pink flame at the mouth of the tube, distils over, accompanied with carbonic oxide gas, and with a gray powder, which is the cause of the occasional choking of the tube. The potassium drops into the naphtha, which protects it from the action of the air; to purify it entirely, it is re-distilled in a small iron retort along with a little naphtha into a receiver containing that liquid. History.—Potassium was discovered in 1807 by Sir H. Davy, who obtained it by decomposing the hydrate of potassa by means of galvan- ism. It was subsequently obtained in larger quantity by Gay-Lussac and Thenard, who placed the fused alkali in contact with iron heated to whiteness, which attracted the oxygen and set free the metal. The common mode of preparing it is given above. Potassium is a solid, soft, bluish-white metal, having a high degree of metallic luster, but becoming quickly tarnished and oxydized when exposed to the air, from which it absorbs oxygen, and should therefore be kept in naphtha, a liquid which contains no oxygen. It is more ductile than wax, and is easily cut with a knife. Its specific gravity is 0.865, so that it floats on the surface of water; it melts at 136°, its equi- valent number is 39.2, and symbol K. When thrown upon water, it swims, takes fire, and burns with a beautiful pink flame, combining with oxygen, and generating potassa which dissolves in the water. It unites with most of the non-metallic elements, and with several of the metals. Metals and metalloids whose attraction for oxygen is too strong to be overcome by the usual means, are isolated by potassium. Thus, it decom- poses the oxides or chlorides of aluminum, glucinum, yttrium, thorium, and zirconium, and the boracic and silicic acids. It is found chiefly in the ashes of land-plants, as oxide of potassa united to carbonic acid, and is also obtained as chloride in the ashes of sea-plants. Many rocks, min- erals, and soils contain it; indeed, it is necessary to the growth of plants. Potassium forms two compounds with oxygen, a protoxide, KO, con- taining one equivalent of oxygen, (a dry potassa) of a gray color; and a peroxide K03, containing three equivalents of oxygen, and of a yel- lowish-brown color. Its protoxide forms the following medicinal salts, acetate, bichromate, carbonate, bicarbonate, chlorate, citrate, hydrate, nitrate, sulphate, sulphureted sulphate, bisulphate, tartrate and bitar- trate of potassa. Potassium also forms officinal compounds with various agents, under the names of iodide, bromide, sulphuret, cyanuret, and ferrocyanuret of potassium, each of which will be described under its appropriate head, throughout this work. Potassae Bitartras. 765 POTASSAE BITARTRAS. Bitartrate of Potassa. History.—This salt, commonly called Cream of Tartar, in its pure state was unknown until the investigations of Scheele in 1769. It is obtained from the crude tartar, argol, or winestone of commerce, a gray- ish or brownish obscurely crystalline substance, which becomes deposited on the bottom and sides of casks in which new wine has been kept. The tart wines deposit it in the largest quantity; it is composed of bitartrate of potassa, tartrate of lime, coloring matter, and other accidental impu- rities. That called Red Tartar, is of a reddish color, and is the deposit of red wines ; while that named White Tartar, is of a dirty-white color, and obtained from white wines. The juice of the grape contains bitar- trate of potassa in solution with saccharine matter, and during its fer- mentation the sugar disappearing and becoming replaced by alcohol, which does not hold the bitartrate in solution, this consequently precipi- tates as a crystalline crust. To purify this substance, it is pulverized, and then boiled with water, and as soon as the solution is saturated, it is allowed to cool, when a nearly colorless crystalline layer is deposited ; this is again dissolved in boiling water, four or five per cent, of pipeclay added to it, and the solution then evaporated to a pellicle. As it cools, the clay and coloring matter subside, and white crystals in crusts are deposited, which become still whiter when placed on linen and exposed to the air. In pharmacy, these are the crystals of tartar; and when powdered form the medicinal cream of tartar. Bitartrate of potassa when first prepared is in the form of white cakes, with obscure crystallization on one of the surfaces ; the crystals being of small size, and in oblique rhombic prisms. But as more generally met with it is in the form of a fine white powder. The crystals are hard and gritty between the teeth, and do not quickly dissolve in the mouth. In either form, it has a sharp, agreeable, acid taste, an acid reaction, is permanent, soluble in 184 parts of cold water, 18 of boiling, and is insoluble in alcohol. A red heat chars and decomposes it, disengaging empyreumatic oil, pyrotartaric acid, and various gases, and leaving car- bonate of potassa with charcoal. The black flux of chemists is composed of one part bitartrate of potassa, and half a part of nitrate of potassa, mixed and heated together ; a residuum is left of carbon and carbonate of potassa. If the nitre be doubled the carbonate will remain without the carbon, forming while flux. Cream of tartar is abundantly soluble in water to which borax or boracic acid has been added, forming a solution, termed Soluble cream of tartar. It is incompatible with baryta, strontia, lime, and acetate of lead, which precipitate insoluble tartrates, and tar- trate of lead. It forms soluble tartrates with salifiable bases, giving rise to double salts. It is composed of two equivalents of acid 132, one of potassa 47.2 and one of water 9=188.2, (2T+KO+Aq). 766 Materia Medica. Commercial cream of tartar usually contains from two to five per cent. of tartrate of lime not intended as an adulteration. But it is sometimes adulterated with sand, clay, gypsum, flour, chalk, nitre, alum, sulphate of potassa, chloride of potassium, etc. Sand, clay, and gypsum may be known by their insolubility ; flour, by giving a blue color with iodine ; chalk, by effervescing with dilute acids ; alum, by its astringency; and any soluble sulphate, by the addition of chloride of barium, which occasions a precipitate not entirely soluble in nitric acid. Chloride of potassium may be detected by nitrate of silver, which produces a white flocculent precipitate insoluble in nitric acid. Properties and Uses.—Bitartrate of potassa is refrigerant, diuretic, and cathartic. In large doses it is apt to give rise to severe and loner-con- tinued purging of watery stools, — yet it does not cause griping at the time, nor debility afterward ; from this property, as well as its diuretic action, it is very much used in dropsical affections. It is frequently combined with Jalap, the Compound Powder of Jalap, Podophyllin, Sulphur, etc. In solution, sweetened with sugar, it forms an agreeable, refrigerant drink, very useful in many febrile affections. Combined with sulphur, it is used as a laxative, and is often given for some forms of cutaneous disease. Dose, as a cathartic, from four to six drachms ; as an aperient, one or two drachms ; and in dropsy, it may be given in doses of from one to three drachms, in water, several times a day. Equal parts of Bitartrate of Potassa, Powdered Rhatany Root, and Myrrh, form a good dentifrice. Two drachms of cream of tartar added to a pint of milk, form a cream of tartar whey, which when diluted with water is sometimes given in dropsical complaints. Off.

History.—Nitrate of Potassa (Saltpetre, Nitre, Sal-prunelle) is a salt which was known to the ancients, though, probably, not with sufficient accuracy to enable them to determine it from other salts formed on the surface of the soil by efflorescence. It may be artificially manufactured, although it exists naturally in some soils. In many countries it exists already formed; thus, it is found in this country in Ohio, Kentucky, Tennessee, Virginia, and Maryland, generally in caverns situated in limestone rock, and intermixed with nitrate of lime. It is also found in various sections of Europe, in Egypt, in Peru, and other countries; but by far the greater part of the commercial article is obtained from India, where it exists in great abundance. The vegetable kingdom contains a considerable portion of it, having been found in the crawley, sunflower, borage, hemlock, parietaria, bugloss, tobacco, etc. Potassae Nitras. 767 In India, where it is manufactured, the soil contains about six or seven parts of nitre in a thousand; this is lixiviated in an apparatus made for the purpose, and containing wood ashes, which has the effect of converting any nitrate of lime that may be present, into nitrate of potassa. The liquid obtained is then evaporated, filtered, and set aside to crystallize, and furnishes a substance containing from 45 to 70 per cent, of the pure salt. This, when redissolved and again crystallized, is the crude nitre, or crude saltpetre of commerce; it has a dirty yellow- ish hue, and contains much foreign matter. An. essential part of these soils is, that they shall contain decomposing felspar, mica, or other destructible minerals which consist partly of potassa. The production of nitre from them is promoted by the presence of animal matter, but may also go on without it; so that the nitric acid must be formed through the intervention of atmospheric air. The soluble salts of the nitrate soils consist of sulphates, muriates, and nitrates of potassa, lime, and soda. The nitrates are converted into nitrate of potassa by lixivi- ating the soil over a filter of wood ashes, containing carbonate of potassa, and then duly evaporating the filtered liquor. Nitre is also prepared in many parts of Europe from soils artificially impregnated with animal matter—from the mortar of old buildings—or from artificial composts consisting of animal substances, decaying vegetables, ashes, and chalk, marl, or lime. The nitrate thus in the first place produced is the nitrate of lime, which is converted into the nitrate of potassa by double decomposition with carbonate of potassa; and the salt is then obtained by lixiviation, and purified by repeated crystallization. On account of the low price of India nitre, but little of the salt is prepared from the native sources of this country ; it is chiefly imported from Calcutta, in grass-cloth bags holding from 150 to 175 pounds each. In this country it is refined by our chemists, of which refined saltpetre a great portion is exported. The South American saltpetre, incorrectly so called, which has been received from Peru within a few years, is a nitrate of soda, and is found to be preferable to nitre in the preparation of nitric and sulphuric acids, in consequence of its containing a greater proportion of acid. As it absorbs moisture, it is not adapted to the manufacturing of gunpowder. Nitrate of potassa forms white, long, striated, translucent crystals, which are six-sided prisms, terminated by one, two, or six converging planes. Its taste is peculiar, cooling, and slightly bitterish. It is per- manent in the air, soluble in about two-fifths of its weight of boiling water, soluble in four or five times its weight of water at 60°, sparingly soluble in ordinary alcohol, but insoluble in absolute alcohol. In the act of dis- solving it occasions considerable cold. Heat fuses it, and when raised to redness drives off oxygen and converts it into the hyponitrite of potassa. In consequence of this evolution of oxygen, it greatly enlivens combustion when thrown on burning fuel. Chloride of platinum added 768 Materia Medica. to its solution, occasions a yellow precipitate. On account of its liability to hold mechanically a portion of water, within the large crystals, it is advised by Berzelius to stir the mixture during crystallization, so as to make it shoot into small crystals. When allowed to cool from a state of fusion, either in molds or flat circular cakes, it concretes into a hard, fibrous, opake, white mass, known in commerce by the name of Sal Pru- nelle, or Crystal Mineral. Nitrate of Potassa consists of one equivalent of nitric acid 54, and one of potassa 47.2= 101.2. (NOo-j-KO.) Its most common impurity is salt, which renders it inapplicable to the purpose of making gunpowder. The presence of salt, or of chloride of potassium, may be known by the addition of nitrate of silver to the solution, which will occasion a white precipitate of chloride of silver. If the chloride of barium produces a precipitate, the impurity is a sul- phate. If lime be present, the addition of a solution of oxalate of ammonia precipitates the white oxalate of lime. The fracture of pure nitrate of potassa is radiated, the radii being usually large; if l-80th of common salt be present, it renders the radii smaller; and l-40th, or more, gives rise to a zone in the body of the mass without any radi- ated structure, or occasions the entire disappearance of this structure. One hundred grains of dry, pure nitre, treated with sixty grains of sul- phuric acid, in a deep platina or porcelain crucible covered to prevent loss during the desiccation of the salt, and the whole kept at a red-heat until it ceases to lose weight, should yield a residue of eighty-six grains of sulphate of potassa; if less than this, and chlorides and sulphates are absent, the nitre probably contains nitrate of soda. Properties and Uses.—Nitrate of potassa is irritant, cathartic, refrige- rant, and diuretic. In doses of from half an ounce to two ounces, in solution, it occasions heat and pain in the stomach, vomiting, excessive nervous depression, and sinking of the pulse; and has proved fatal in a few hours. On account of the uncertainty of its cathartic effects, it is seldom used for that purpose. Its most common actions are to increase the cutaneous and renal secretions, to diminish the temperature of the system and the frequency of the pulse, to keep the bowels in a soluble condition, and, in consequence of these influences, to lessen febrile and inflammatory action. An experiment, in which from one to five drachms of nitre were given daily, in a state of health, and continued for eight or twelve days, resulted in general debility, lowness of spirits, constant drowsiness, and slow and weak pulse, falling, toward the termination of the experiment, at several various times, to twenty beats in the minute. All this time the appetite and digestion continued unimpaired, with occa- sional pains in the abdomen followed by purging. Nitre is extensively employed as a diuretic, and especially in dropsical affections. It has also been found useful in acute rheumatism, and active hemorrhages; and in such cases the salt may be given in divided doses, to the extent of one or two ounces in twenty-four hours, care being taken to have it Potassii Ferrocyanuretum. 769 largely diluted with water. In spasmodic asthma it has been adminis- tered internally with efficacy; nitrous fumigation has also been found useful in this affection; it is employed as follows : blotting-paper is dipped in a saturated solution of nitre and dried, fire is then applied to it, and the nitrous fumes that are evolved are to be inhaled, continuing the in- halation each time for a quarter of an hour. Nitre is sometimes added to gargles in certain stages of inflammatory sore-throat. It is fre- quently substituted for the bitartrate of potassa in our Powder of Ipe- cacuanha and Opium. Sal prunelle has been found useful as an appli- cation to chapped lips. The dose of nitre, as a sedative refrigerant, is from ten to twenty grains, well diluted; and as a diuretic, from twenty to sixty grains. Too freely given, or its use too long continued occa- sions pain in the stomach. No antidote is known to its more serious actions; the treatment consists in speedily evacuating it from the sto- mach, administering mucilaginous draughts in large quantities, anodynes to relieve pain and irritation, and stimulants to overcome any tendency to prostration.

Ferrocyanuret of Potassium. History.—On the large scale, this salt is prepared by placing a mix- ture of two parts of pearlash, with five parts of animal matter, such as hoofs, dried blood, old leather, chips of horn, woolen rags, and other substances abounding in nitrogen, into an egg-shaped iron pot, calcining the mixture at a red-heat, and constantly stirring the mass until it ceases to give out fetid vapors. The calcined mass is then cooled, dissolved in water, and concentrated by evaporation so that crystals may form. These are purified by repeated crystallization. It may also be obtained by boiling purified Prussian blue in a solution of potassa, until the blue color disappears, filtering the liquor, evaporating, and crystallizing several times to render it pure. Ferrocyanuret of Potassium occurs in broken or entire crystals of large size, whose form is usually a rectangular prism, truncated on the ends and edges, or a foursided table derived from the rhombic octaedre by excossive truncation of the apices. They are transparent, of a lemon- yellow color, permanent in the air, somewhat flexible, inodorous, and possessed of a sweetish-bitter, saline taste. It is soluble in three or four times its weight of Qold water, and about its own weight of boiling water, but is insoluble in alcohol. At a temperature of 140° it loses its water of crystallization, leaving a white anhydrous salt. A low red-heat, decomposes it, converting it into cyanuret of potassium, carburet of iron, 49 770 Materia Medica. and other compounds. The salts of sesquioxide of iron are precipitated of a deep-blue color by it; those of protoxide of iron white, quickly passing to blue ; those of zinc and lead white, and of copper chestnut- brown. The precipitates are ferrocyanurets of the respective metals. It emits a hydrocyanic acid vapor when boiled with dilute sulphuric acid. It consists of two equivalents of cyanuret of potassium 130.4, one of cyanuret of iron 54, and three of water 27 = 211.4, (2 K Cy, Fe Cy-f- 3 HO). In the anhydrous state, it is stated to consist of a compound radicle called Ferrocyanogen, which is composed of three equivalents of cyanogen, and one of iron (tercyanuret of iron) combined with two equivalents of potassium, (2 K Cy, Fe Cy), or (Fe Cy3-|_2 K.) Properties and Uses.—Ferrocyanuret of potassium is not poisonous, being absorbed and carried off quickly with the urine. " Dr. Burleigh Smart, of Kennebec, Maine, has attributed to this salt valuable medicinal powers. Its primary effect, according to him, is that of a sedative, diminishing the fullness and frequency of the pulse, and allaying pain and irritation. It also acts, under favorable circumstances, as a diapho- retic and astringent. Dr. Smart used it with success in a case of chronic bronchitis in a child, with the effect, in a few days, of diminishing the frequency of the pulse, and of lessening the sweating, cough, and dys- pnoea. It sometimes acts as a diaphoretic, but only in cases attended with excessive vascular action, and increased heat of skin. As an astringent, its power is most conspicuous in the colliquative sweats of chronic bronchitis and phthisis. The same power was evinced in several cases of leucorrhea, cured by its use. It sometimes produces ptyalism, unattended, however, by swelling of the salivary glands, or fetor of the breath. Its properties as an anodyne and sedative, render it applicable to cases of neuralgic pains and hooping-cough, in which diseases, especially the latter, Dr. Smart found it useful. When given in an over- dose, he states that it occasions vertigo, coldness and numbness, with a sense of gastric sinking. " The form of administration which Dr. Smart prefers, is that of solution in the proportion of two drachms to the fluidounce of water. Of this, the dose for an adult is from thirty to forty-five drops, equivalent to from ten to fifteen grains of the salt, repeated every four or six hours. Should the results of Dr. Smart be confirmed by the profession, the ferrocyanide of potassium will form an important acquisition to the Materia Medica."—U. S. Disp. Off.

Syst.—Icosandria Polygynia. THE ROOT. Description.—This is a perennial, villose-pubescent plant, frequently known by the name of Cinque-foil. It has a sarmentose, procumbent and ascending stem from two to eighteen inches in length. The leaves are palmately five-foliate, the leaflets obovate, silky beneath, cut-dentate toward the apex, entire and alternate toward the base. Stipules ovate, hairy, deeply two or three-cleft, or entire. The fiowers are yellow, on long, axillary, solitary pedicels. The calyx-segments are lanceolate or linear; bracetoles of the calyx longer than the segments, and nearly as long as the petals; petals obcordate, and longer than the calyx. There are two varieties of this plant, the Potentilla Pumila, which is very small and delicate, flowering in April and May, and growing in dry, sandy soils, the stem rising about three or four inches. The other is the Potentilla Simplex, which is less hirsute, with a simple stem, erect or ascending at base, and oval-cuneiform leaflets ; it grows in richer soils to twelve and sixteen inches high, and flowers from June to August. History. — Five-finger is common to the United States, growing by roadsides, on meadow banks and waste grounds, and flowering from April to October. It is the Potentilla Sarmentosa of some botanists. The root is the part used; it has a bitterish, styptic taste, and yields its virtues to water. Properties and Uses.—This plant is a tonic and astringent. A decoc- tion has been found useful in fevers, bowel complaints, night sweats, menorrhagia, and other hemorrhages; also it is an excellent local application in form of gargle, for spongy, bleeding gums, and ulcerated mouth and throat. The European herb, Potentilla Reptans, possesses similar properties. Off. Prep.—Decoctum Potentillae. POTENTILLA TORMENTILLA. Tormentil. Nat. Ord.—Rosaceas. Sex. Syst.—Icosandria Polygynia. THE ROOT. Description.—Tormentil or Septfoil, is the Tormentilla Erecta of Will- denow, and the Tormentilla Officinalis of Smith. It has a perennial, tough, woody root or rhizoma, about the thickness and length of the upper joint of the fore-finger, with numerous radicles. The stems are slender, weak, erect, often procumbent, branching toward the top, and six or eight inches high. The leaves are almost sessile, and consist on the stalk of seven, on the branches of five palmate, elliptical, villous, 772 Materia Medica. deeply serrated leaflets, three of which are larger than the others. The flowers are small, bright-yellow, with the parts of the calyx and corolla in fours, on slender axillary hairy stalks much longer than the leaves. Carpels corrugated when ripe. History.—Tormentil or Septfoil is a plant common to Europe. All parts of it are astringent, but the root is the part usually employed. It is cylindrical or roundish, rather larger at its upper extremity, an inch or two in length, about as thick as the finger, knotty, sometimes con- torted, brown or blackish externally, and reddish within. It has a slight aromatic odor, and a veiy astringent taste. It yields its virtues to boiling water. It contains an abundance of tannic acid, a red coloring principle soluble in alcohol, but insoluble in water, resin, cerin, myricin gummy-extractive, gum, lignin, extractive, water, and a trace of volatile oil. It is said to be used in some of the islands of Scotland for tannin^ o leather, and in Lapland for staining leather red. It is equally applicable in medicine with catechu, kino, and other foreign astringents. Properties and Uses.—A simple and powerful astringent; used in all cases of disease in which this class of medicines is indicated. It may be given in substance, decoction, or extract. Dose of the powder, from thirty to sixty grains. Off. Prep.—Decoctum Tormentillae. PRINOS VERTICILLATUS. Black Alder. Nat. Ord.—Aquifoliaceae. Sex. Syst.—Hexandria Monogynia. THE BARK AND BERRIES. Description.—This is an indigenous shrub of irregular growth, some- times known as Winterberry, having a stem six or eight feet in hight, with a bluish-gray, or ash-colored bark, and alternate, horizontal, and spreading branches. The leaves are alternate, or irregular, on short petioles, oval, acute at the base, pointed, sharply serrate, of an olive- green color, smooth above, and pubescent beneath, particularly on the veins. The flowers are small, white, dicecious, on very short peduncles ; the fertile ones somewhat clustered or solitary ; the sterile ones sub-um- bellate ; sometimes the flowers are monoecious. The calyx is small, six- cleft, persistent. Corolla monopetalous, spreading, without a tube, the border divided into six obtuse segments. The stamens are equal in number to the divisions of the corolla, erect, with oblong anthers ; in the fertile flowers they are shorter than the corolla, in the sterile they are equal in length to it. The ovary is large, green, roundish, with a short style and obtuse stigma. The fruit consists of bright scarlet, globular berries, about the size of a pea, supported by the persistent Prunus Virginiana. 773 calyx, and crowned with the stigma, six-celled, containing six long seeds, which are convex outwardly, and sharp-edged within. Several of them are clustered together so as to form little apparently verticillate bunches at irregular intervals on the stem. History.—Black Alder is found in nearly all parts of the United States, from Canada to Florida, in moist woods, swamps, borders of ponds, ditches, etc., flowering in July, and ripening its fruit late in autumn. The bark and berries are officinal. The dried bark is in slender pieces, more or less rolled, brittle, greenish-white internally, and covered with a smooth, whitish ash epidermis, alternating or mingled with brown, and easily separable. It has a bitter, slightly astringent taste, but no smell. Boiling water extracts its virtues. The berries are sometimes, but improperly, substituted for the bark, they have a sweet- ish, bitter, acrid taste, and impart their virtues to water or alcohol. These have not been analyzed. Properties and Uses.—Black Alder is tonic, alterative, and astringent. It has been used with good effect in jaundice, diarrhea, intermittent fever, and other diseases connected with a debilitated state of the system, especially gangrene and mortification ; it has also been of service in dropsy. Two drachms of the powdered bark and one drachm of powdered golden-seal, infused in a pint of boiling water, and when cold, taken in the course of the day, in doses of a wineglassful, and repeated daily, has proved very valuable in dyspepsia. Externally, the decoction forms an excellent local application in gangrene, to ill-conditioned ulcers, chronic cutaneous eruptions, etc. The berries are cathartic and vermi- fuge, and form, with cedar-apples, a pleasant and effectual worm medi- cine for children. (See Juniperus Virginiana.) Dose, of the powdered bark, from half a drachm to one drachm; of the decoction four fluidounces three or four times a day. Black Alder bark is an ingredi> ent of several alterative syrups. Off. Prep.—Decoctum Prinos. PRUNUS VIRGINIANA. Wild Cherry. Nat. Ord.—Drupaceae, De Candolle; Amygdaleas, Lindley. Sex. Syst.—Ico- sandria Monogynia. THE BARK. Description.—This tree is the Cerasus Serotina of De Candolle, and the Cerasus Virginiana of Michaux; it is a large tree, and has been seen from eighty to one hundred feet high. Its usual size, however, is from fifty to eighty feet high, from two to four feet in diameter, being of uni- form size and undivided to the hight of twenty or thirty feet. The bark is black and rough, which spontaneously detaches itself semicircularly, 774 Materia Medica. in thick narrow plates. The wood is compact, fine-grained, and receives a fine polish, and is extensively used by cabinet manufacturers. The leaves are deciduous, oval-oblong, or lanceolate-oblong, acuminate, une- qually serrate, with incurved, short and callous teeth, thickish, smooth on both sides, except the midrib, shining above, of a beautiful brilliant green, from three to five inches long, and one-half as wide, and supported alternately on petioles, which are furnished with one or two pairs of red- dish glands. The flowers are small, white, and disposed in elongate, spreading, and sometimes pendulous racemes. The fruit is a globular drupe about the size of a pea, of a purplish-black color, edible, but having a bitter taste. History.—The Wild Cherry tree is found in many parts of the United States, but is most abundant, and attains the greatest magnitude, in the south-western States. Its flowers appear in May, and the fruit ripens in August and September. The officinal portion is the bark, and that of the root should be preferred to that of the trunk or branches. When dried and prepared for use, it is in pieces of various lengths and sizes, deprived of epidermis, of a reddish-brown color, bitter, and easily pul- verized. Its powder is of a fawn color. When recent, or when boiled in water, it emits an odor resembling that of peach-leaves ; and its taste is agreeably bitter and aromatic, with a flavor similar to that of peach- meats. It imparts its properties to alcohol or water, whether hot or cold; but boiling destroys its remedial qualities, partly in consequence of the escape of its volatile principle, and partly upon a chemical change effected by the heat. It should be employed in a recently dried state, as its properties are much impaired by keeping. Mr. S. Procter found it to contain starch, resin, tannin, gallic acid, fatty matter, lignin, red coloring matter, salts of lime and potassa, and iron, also a volatile oil associated with hydrocyanic acid, of a light-straw color, and analogous in its properties to the essential oil of bitter almonds. Two drops of it destroyed a cat in nearly five minutes. This volatile oil and the hydro- cyanic acid do not exist ready formed in the bark, but are caused by the reaction of water upon amygdalin, which is one of the constituents of the bark; and which change is very probably effected by the agency of another principle, analogous to, if not identical with, emulsin, or the synaptase of Robiquet. Properties and Uses. — Tonic and stimulant in its operation on the digestive organs, and at the same time exercising a sedative influence on the circulatory and nervous systems. It is, therefore, useful in all dis- eases where it is of importance to impart tonicity, and yet, to avoid any undue excitement of the heart and blood-vessels, as for instance, during the first stage of convalescence from inflammatory attacks, and in many pulmonary diseases. It is very generally used in phthisis, where hectic fever exists, and has also been used with benefit in some forms of Prunus Virginiana. 775 dyspepsia. In large doses it diminishes the action of the heart, owing pro- bably to the hydrocyanic acid which it affords. It has likewise been of service in scrofula and other diseases attended with much debility and hectic fever. Externally it has been found useful in decoction as a wash to ill-conditioned ulcers. An excellent preparation is a syrup made by macerating four ounces of the powdered bark with twelve fluidounces of water, for two days ; the mixture is then placed in a percolator or dis- placement apparatus, returning the liquid which passes till it comes away clear—displacing with an additional quantity of water, until twelve fluidounces of infusion are obtained, and then dissolving in this thirteen ounces of loaf sugar ; the dose of this syrup is from half a fluidounce to one ounce. Dose of the powdered bark, one or two drachms ; of the infusion, one ounce of bark to one pint of cold water, and allowed to stand a few hours, from one to four fluidounces, four or five times a day, and which is the best mode of using it. The Prunus Domesticus, or cultivated Prune or Plum Tree, may be referred to here. The dried or prepared fruit is the only officinal part, and furnishes the prunes of commerce. Those imported into this country, are principally from the south of France, the finest kinds eoming from the port of Bordeaux. A poorer kind is brought from Germany. Prunes are prepared by exposing the fresh fruit to the heat of an oven, and then drying in the sun. They have a faint odor, a sweet, mucilaginous, somewhat acid taste, and contain crystallizable and uncrystallizable sugar, malic acid, and mucilaginous matter. In Ger- many a kind of brandy is obtained from this fruit, and which may be sometimes had of the importers of German liquors. Prunes are laxa- tive and nutritious, and stewed with water form an excellent diet in cases of constipation, and also during convalescence from febrile or inflamma- tory diseases. They are often added to purgative decoctions, and the pulp is employed in the preparation of laxative confections. When taken too largely, and especially in those whose digestive organs are debilitated or impaired, they are apt to cause flatulence, and griping. The following preparation has been administered with much success in leucorrhea, irregular menstruation, and in debility from frequent abor- tions : Take of small raisins or dried currants two ounces, aniseed, mace, and cinnamon, of each, half an ounce, and one nutmeg in powder ; to these add one quart of prune brandy, and let them macerate for two weeks, frequently agitating. This is the formula as originally given. Of the clear tincture thus made, one fluidounce may be given previous to a meal, and repeated three times daily. Off.

Syst.—Tetrandria Monogynia. THE BARK OF THE ROOT. Description.—This plant is also known by the names of Wingseed, Wafer-Ash, and Swamp-Dogwood. It is a shrub from six to eight feet in hight, with the leaves trifoliate, and marked with pellucid dots; the leaflets are sessile, ovate, short acuminate, downy beneath when young, crenulate, or obscurely toothed; lateral ones inequilateral, terminal ones cuneate at base, from three to four and a half inches long by one inch and a quarter to one inch and three-quarters wide. The flowers are polygamous, greenish-white, nearly half an inch in diameter, of a dis- agreeable odor, and disposed in terminal corymbose cymes. Stamens mostly four; style short. Fruit a two-celled samara, nearly an inch in diameter, winged all round, nearly orbicular. History. — Shrubby Trefoil or Ptelea, is a shrub common to this country, growing more abundantly west of the Alleghanies in shady moist hedges and edges of woods, and in rocky places; it flowers in June. The bark of the root is officinal, and yields its properties to boiling water; but alcohol is its best solvent. It is, when dried, of a light brownish-yellow color externally, in cylindrical rolls or quills, a line or two in thickness, and from one to several inches in length, irregu- larly wrinkled and furrowed externally, with broad, transverse lines or rings at short but irregular intervals, and is covered with a thin epidermis; internally it is yellowish-white, but becomes darker on exposure, and is wrinkled longitudinally; it is brittle with an almost smooth, resinous fracture, granular under the microscope, resembling wax. It has a peculiar smell, somewhat similar to that of liquorice-root, and a peculiar bitter, resinous, pungent, acrid, and rather disagreeable taste, speedily and powerfully acting upon the mouth and fauces, and the pungency of which is persistent, and which is probably owing to its oil. It has not been analyzed. The fruit is bitter and aromatic. Properties and Uses.—Ptelea is tonic. Used in intermittent fevers, remittent fevers, and all cases of debility where tonics are indicated. Said also to be anthelmintic. Equal parts of Ptelea and the Euonymus Atropurpureus, have been highly recommended in pulmonary affections. A tincture of Ptelea, made in whisky, is reputed to have cured several cases of asthma, and it is said to cause, in many instances where it has been used, a troublesome external erysipelatous inflammation, either general or local, but which, if the use of the tincture be persisted in, finally disappears, and the patient becomes at the same time perma- nently cured of the disease for which he was treated. This would certainly indicate other valuable properties in this plant, than those with Ptelein. 777 which we are acquainted, and deserves a further and thorough investi- gation. It may be used in powder, tincture, or extract. Dose of the powder, ten to thirty grains, three or four times a day ; of the tincture, one or two fluidrachms ; of the extract, five to ten grains.

Preparation.—Make a saturated tincture of the bark of Ptelea Tri- foliata. add to it twice its volume of water, and distil off the alcohol; the ptelein remains in the water, from which it must be separated. History.—Ptelein, I believe, was first prepared by Mr. W. S. Mer- rell, and is obtained from the tincture of the bark by precipitation with water, in the same manner by which podophyllin, iridin, eupurpurin, etc., are obtained. It is of the consistence of thick syrup or molasses, dark- brown in mass, much lighter when in thin layers, and has a peculiar odor, somewhat similar to that of the extract of liquorice, and an oily, bitterish, acrid, persistent taste, peculiar and rather disagreeable, and acting power- fully on the fauces. It is soluble in alcohol, ether, oil of turpentine, and rather imperfectly in alkaline solutions ; insoluble in acids and water. It imparts a slight milky color to water, and separates into two portions, one of which floats on the water, while the other sinks. Acetic acid added to its alcoholic or ethereal solution does not disturb them, unless added in excess. Water added to the alcoholic solution produces a milky color, precipitating the resin; added to the ethereal solution it sepa- rates the oil, which floats on the surface. Properties and Uses.—Ptelein is a tonic, and possesses other proper- ties not yet satisfactorily understood. It is a valuable medicinal agent, which should receive the especial attention of the profession. I have used it extensively and successfully in cases of dyspepsia, combined with equal parts of Xanthoxylin, and given in doses of one or two grains, repeated three times a day; if constipation be present, I have found the following an admirable combination: Take of ptelein nineteen grains, alcoholic extract of nux vomica one grain, white sugar, or lactin, two drachms. Mix thoroughly together; the dose is six grains to be repeated three or four times a day. I have found the following a valuable pill in chronic erysipelas, hepatic torpor, enlarged spleen, habitual constipation, chronic dysentery, and some forms of dyspepsia: Take of podophyllin and leptandrin, of each one grain, sulphate of quinia four grains, ptelein eight grains; mix these together, and divide into eight pills. The dose is one pill, to be repeated two or three times a day, and the alkaline bath to be used daily. 778 Materia Medica. PTERIS ATROPURPUREA. Rockbrake. Nat. Ord.—Filices ; Polypodiaceae, Brown. Sex. Syst.—Cryptogamia Filices. THE PLANT. Description.—Rock-brake is an indigenous perennial fern, with a frond from six to ten inches in hight, twice as long as wide, of a gray- ish hue, pinnate, the two lower divisions consisting of from one to three pairs of leaflets with a large, terminal segment. The stipe and rachis, dark-purple, shining, with dense, paleaceous hairs at base. The lower leaflets ternate or pinnate, lanceolate, obtuse, distinct, obliquely truncate or subcordate at base, with margins conspicuously revolute. Involucre rather broad, formed of the inflected margin of the frond, and opening inwardly. Sori in a broad continuous line along the margin of the frond. The several varieties of this species possess similar properties, as the Pteris Venosa, with the stipe angled, and the leaflets veined beneath; P. Punctata, with the stipe terete, and the leaflets punctate beneath. The Pteris Aquilina or common Brake likewise possesses analogous virtues. It is a fern from two to five feet in hight, upon a smooth, dark- purple, erect stipe. The frond is pinnate, three-parted, broad-triangular in outline. The branches are bipinnate. The leaflets linear-lanceolate; the lower ones pinnatifid, the upper ones entire; segments oblong, obtuse. Sori covered by the folding back of the margins of the segments. History.—Rock-brake is common to the United States, usually grow- ing on limestone rocks; the common Brake is found in greater abundance, in woods, pastures, waste grounds, and stony hills. The whole plant is used in medicine, and imparts its virtues to water. No analysis has been made of it. As found in the shops, the dried root consists of a long cylindrical caudex, of a dark-brown color externally, and light brownish-red internally, of an astringent, leathery taste and around which are closely arranged, overlapping each other like the shingles of a roof, the remains of the leafstalks or stipes, which are an inch or two in length, from two to four lines thick, somewhat curved and directed upward, angular, dark-brown, furrowed longitudinally, and from between which, emerge numerous small radical fibers. The dried leaves are of a light-grayish or greenish-yellow color, of an odor resembling that of sole leather, and a leathery, astringent, not disagreeable taste. As sold, it is usually in broken fragments. Properties and Uses. — Rock-brake is astringent and anthelmintic. A decoction of it, taken moderately, has proved efficacious in diarrhea, dysentery, night-sweats, and hemorrhages; and used as a local applica- tion, it is beneficial in obstinate and ill-conditioned ulcers, ulcerations of the mouth and fauces, and, as a vaginal injection in leucorrhea. A Pterocarpus Santalinus. 779 strong decoction is in some repute as a remedy for worms. A power- ful astringent infusion may be made by adding four drachms of the plant to one pint of boiling water, and which has been used in diarrhea and dysentery, in half fluidounce doses repeated every two or three hours, with success. A plant called Winter-fern or Brake is much employed in amenorrhea, and in suppression of the lochia; it is used in infusion, and taken freely. By some it is supposed to be the Pteris Atropurpurea ; but of this I am not positive, not having been able to obtain a perfect specimen of the plant for examination. Both the roots and tops are used, and are worthy the attention of the practitioner in the above-named derangements. PTEROCARPUS SANTALINUS. Red Saunders. Nat. Ord.—Fabaceas, or Leguminosas. Sex. Syst.—Diadelphia Decandria. THE WOOD. Description.—This is a large tree with alternate branches. The leaves are petiolate, ternate, and alternate ; the leaflets are alternate, petiolate, the uppermost larger, ovate-roundish or oblong, entire, emarginate or refuse, veined, smooth above, and hoary beneath. The flowers are yellow, in axillary, erect, simple or branched racemes; the corolla is papilionaceous, the vexillum or banner of which is obcordate, erect, somewhat reflexed at the sides, toothed and waved, having red veins; the alee or wings spreading, with their edges apparently toothed, and the carina or keel oblong, short, and inflated. The calyx is brown. Filaments ten, diadelphous. Legume roundish, stalked, falcate upward, compressed, smooth, keeled on the lower edge, the keel being mem- branous and undulated. Seeds solitary. History.—This is a large forest tree inhabiting Ceylon, and the moun- tains of the opposite Coromandel coast on the Indian continent. The wood is the officinal Red Saunders or Red Sandal wood. It is imported in billets which are dense, heavy, dark-brown externally, and internally dark-red with light-red rings. It is usually kept in the shops in the state of small chips, raspings, or coarse powder. It has a faint, pecu- liar odor, and an obscurely astringent taste, and is of difficult pulveriza- tion. It may be distinguished from other coloring woods, by imparting a red color to alcohol, ether, and alkaline solutions, but not to water. The alcoholic tincture causes a deep violet precipitate with the sulphate of iron, a scarlet with the bichloride of mercury, and a violet with the soluble salts of lead. About seventeen per cent, of a yellow resinoid, coloring principle was obtained from it by Pelletier, which became red from the action of the air; he named it Santalin Cio Hi6 03. It may be obtained either by precipitation of the tincture with water, or by 780 Materia Medica. preparing an infusion with an alkaline solution, and precipitating with an acid. It is insoluble in water, soluble in alcohol or ether, slightly soluble in volatile oils, with the exception of those of lavender and rosemary, which readily dissolve it. Soluble in acetic acid, and readily soluble without decomposition in alkalies; the acetic solution is somewhat astringent to the taste, and is precipitated by solution of gelatin. It is said to be pos- sessed of acid properties. Properties and Uses.—Tonic and astringent; formerly used for these indications, but at present employed only for coloring tinctures, etc. PTEROSPORA ANDROMEDA. Crawley. Nat.

The flowers are pale or reddish-white, lateral, nodding, and disposed in a terminal raceme from six to twelve inches long, and composed of fifty or more flowers; the pedicels are irregularly scattered, from six to eight lines in length, and axillary to long, linear bracts. The calyx is five- parted ; the corolla, is roundish-ovoid, urn-shaped, the limb five-toothed, reflexed, and inclosing the stamens. Stamens ten; fllaments flat; anthers peltate, two-celled, two-awned, opening lengthwise; style short; stigma five-lobed, capitate. Capsule or pod globose, depressed, five-lobed, five- celled, loculicidal. Seeds very numerous, minute, ovoid, tapering to each end, the apex expanded into a broad reticulated wing many times larger than the nucleus. History.—This is a rare and singular plant, found on barren hills and shady uplands, and in hard clay soil, in the State of New York and some other of the northern States and Canada, flowering in July. By some it is supposed to be parasitic on the roots of certain trees. It was first discovered in 1816 by Dr. D. S. C. H. Smith, although long known previous to that time by herbalists. The entire plant is destitute of ver- dure. The root is the officinal part, it is small, dark-brown, resembling cloves or a hen's claw, has a strong, nitrous smell, and a mucilaginous, slightly-bitter, astringent taste. It has not been analyzed, hence its proper menstruums are unknown. — There are four varieties, the P. Pauciflora, or Few-flowered Crawley; the P. Leucorhiza, or White-stalked PULMONARIA OFFICINALIS. 781 Crawley; the P. Flaviculis, or Yellow-stalked Crawley; and the P. Ela- tior, or High-stalked Crawley—all of which possess similar medicinal virtues. The first two are found in the Western States. Properties and Uses.—Crawley is, probably, the most powerful, prompt, and certain diaphoretic, in the Materia Medica, but its scarcity and high price prevent it from coming into general use. It is also sedative, and promotes perspiration, without producing any excitement in the system. Its chief value is as a diaphoretic in fevers, especially typhus, and in inflammatory diseases; it has proved efficacious in acute erysipelas, cramps, flatulency, pleurisy and night-sweats; and relieves hectic fever without debilitating the patient. Probably it will be found to combine tonic, sedative, diaphoretic, and febrifuge properties. Its virtues are especially marked in the low stage of fevers. The dose is from twenty to thirty grains of the powdered root, given in water as warm as the patient can drink, and repeated every hour or two, according to circum- stances. The powder should always be kept in well-closed vials; it con- stitutes the "fever powders" of some practitioners. Combined with caulophyllin it forms an excellent agent in amenorrhea and dysmenor- rhea; and is unsurpassed in after-pains, suppression of lochia, and the febrile symptoms which sometimes occur at the parturient period. In fevers it may be advantageously combined with leptandrin, or podophyl- lin, where it is found necessary to act upon the bowels or liver; and mixed with dioscorein, it will be found almost a specific in flatulent and bilious colic. It is an agent not known in Ailopathie works on medicine, and one which deserves more attention than has been bestowed upon it. PULMONARIA OFFICINALIS. Lungwort. Nat. Ord.—Boraginaceae. Sex. Syst.—Pentandria Monogynia. THE LEAVES. Description.—This is a rough plant, with a stem about one foot in hight. The radical leaves are ovate, cordate, scabrous, and the cauline ones ovate and sessile. The flowers are blue, and in terminal clusters. The calyx is prismatic, five-angled, five-toothed, and as long as the tube of the corolla; the corolla is infundibuliform, wdth a cylindric tube, ori- fice hairy in five lines alternating with the stamens; stigma emarginate; achenia roundish, obtuse, imperforate at base. History.—This is a herbaceous perennial, growing in Europe and this country, in northern latitudes. In Europe it is a rough-leaved plant, but in this country the whole plant is smooth. The Mertensia Virginica, or Vir- ginian Lungwort, or Cowslip, is frequently employed in the United States; it is the Pulmonaria Virginica of Linna3us, and the Lithospermum Pulchrum 782 Materia Medica. of Lehman. It is a smooth, erect and elegant plant, about twenty inches in hight, the radical leaves of which are obtuse, obovate-elliptical, and become from five to six inches long, and about two-thirds as wide, many- veined, and the cauline are long-lanceolate and sessile. The flowers are blue, and in terminal clusters. The calyx five-cleft, much shorter than the tube of the corolla, limb longer than the tube; the corolla is nearly an inch long, funnel-form, four times the length of the calyx, naked in the throat, and the much-spreading border slightly five-lobed, stamens and style included; filaments slender. Disk bearing two glands as long as the ovaries. The stem and leaves are usually pellucid-punctate. This plant is found in alluvial banks, growing from western New York to Georgia and the Western States, and flowering in May. Being a showy plant it is frequently cultivated.—The leaves of these plants are the parts used ; they are inodorous, and have a herbaceous, somewhat mucilaginous, and feebly astringent taste. Water extracts their pro- perties. Properties and Uses.—Demulcent and mucilaginous, and may be used in decoction, whenever this class of agents is indicated. They have been much used in catarrh, hemoptysis, and other diseases of the respi- ratory organs. PUNICA GRANATUM. Pomegranate. Nat. Ord.—Myrtacea?. Sex. Syst.—Icosandria Monogynia. THE RIND OF THE FRUIT AND BARK OF THE ROOT. Description.—The Pomegranate is a beautiful shrub, covered with a brownish bark, with many slender branches, which are more or less spiny. In favorable situations it frequently attains the hight of twenty feet. The leaves are opposite or ternate, sessile, smooth, waved, entire, oblong, inclining to lanceolate, of a bright-green color, two or three inches long, by from five to ten lines wide, and without a marginal vein. The flowers are large, of a rich scarlet color, solitary, or two or three together, terminal. The calyx is turbinate, thick, fleshy, red, and divided into five acute segments, which are valvate in aestivation. The corolla consists of five large, wrinkled, membranous petals, somewhat spreading, and which are inserted into the upper part of the tube of the calyx. The stamens are indefinite, with capillary filaments, and oblong, two-celled anthers, bursting in front by two chinks. The ovary is infe- rior, with a simple style, crowned by a papulose stigma. The fruit is the size of an orange, globular, somewhat compressed, and indehiscent; it is filled with numerous, angular, exalbuminous seeds, each enveloped in a juicy rose-colored pulp, and is crowned with the limb of the calyx, and covered with a thick, tawny, coriaceous rind, which is the dilated calycine tube. This balaust, as it is termed, is divided into two chambers PUNICA GRANATUM. 783 by a transverse diaphragm. The upper chamber is five to nine-celled, and the lower three-celled. The placentae of the upper division extend from the parietes to the center, while those of the lower proceed irregu- larly from the bottom. History.—The Pomegranate is a native of Northern Africa, Syria, Persia, China, and other countries of Asia, and has been naturalized in the West Indies, and other civilized countries in warm latitudes. It has splendid, dark-scarlet flowers, often doubled, which appear in July and August. The fiowers have a bitterish, astringent taste, without odor, and their infusion gives a deep bluish-black precipitate with the salts of the sesquioxide of iron; the saliva is colored agviolet-red upon chewing them. They contain tannic and gallic acids, and together with the seeds are recognized as officinal in some foreign Pharmacopoeias. The fruit varies in size and flavor, that of the West Indies becoming the most perfect; it contains a red, succulent, pleasantly acid, sweetish, and edible pulp. The rind of the fruit, and the bark of the root, are the only parts employed in this country. The Rind of the fruit, ( Granatum, London; Punica? Granati Cortex, Dublin, or Granati Fructus Cortex, United States,) when dry, is yellow- ish or reddish-brown externally, yellow within, about a line in thickness, smooth or finely tuberculated, hard, dry, brittle, in irregular fragments, inodorous, and of a very astringent, slightly bitter taste. Its infusion gives an abundant, dark-bluish precipitate with the salts of iron. It contains 18.8 per cent, of tannin, 17.1 of mucilage, 10.8 extractive matter, 30 lignin, a trace of resin, and 29.9 moisture. The root is large, ligneous, knotty, and hard, and covered with a yellowish-gray, or ash-gray bark, which is yellow on its inner surface. The Bark of the root, (Granati Radicis Cortex), as found in commerce, is generally in quills, or fragments of quills, from two to six inches in length, and from half an inch to an inch in breadth, and nearly a line in thickness ; it is grayish-yellow externally, with green specks, yellow internally, brittle, and not stringy. It breaks with a short fracture, has a faint, peculiar odor, has an astringent, bitter taste when fresh, the bitterness of which is nearly lost by drying. When chewed, it tinges the saliva yellow. Its infusion yields a deep-blue precipitate with the salts of iron, a yellowish white one with a solution of gelatin, a grayish- yellow with corrosive sublimate, and potassa or ammonia colors it purple. The inner surface of the bark, steeped in water and then rubbed on paper, stains it yellow, which becomes blue by the contact of sulphate of iron, and a slight rose tint by that of nitric acid, which soon vanishes. These properties will distinguish it from the barks of the box root and barberry branches, with which it is sometimes adulterated ; the box bark is nearly white, bitter, not astringent, and its infusion is not preci- pitated by salts of iron. The barberry bark, very much resembles the 784 Materia Medica. pomegranate, and is very bitter and not astringent, and is not affected by the salts of iron, solution of isinglass, corrosive sublimate, or potassa. The ligneous portion of pomegranate root is inert, and should, therefore, be always separated from the bark. Pomegranate bark has been analyzed by several chemists, and contains fatty matter, tannic and gallic acids, starch, gum, resin, wax, chlorophylle, a saccharine substance having the properties of mannite, and some insoluble matters. Righini obtained a peculiar oleo-resinous principle from it, which he considers to be the source of its activity and which he named Punicin; it has an acrid taste, and affects the nostrils somewhat similar to veratria. It may be prepared by rubbing a hydro- alcoholic extract of the bark with one eighth of hydrate of potassa, heat- ing the mixture with eight parts of pure water gradually added, then dropping in dilute sulphuric acid to neutralize the alkaline solution, and washing on a filter with cold water; the punicin separates and is obtained in the filter. Properties and Uses.—The flowers and rind of the fruit are astrin- gent, and have been used for arresting chronic mucous discharges, passive hemorrhages, aphthous disorders of the mouth, night-sweats, colliquative diarrhea, etc., but are now seldom employed. The rind has also been found serviceable in intermittent fever, and tapeworm. The bark of the root possesses anthelmintic properties, and is chiefly serviceable in tapeworm. The bark of the wild pomegranate is consi- dered by the French to be more active than the cultivated plant. It may be given in powder, but the decoction is generally preferred. Two ounces of the bark are to be steeped in two pints of water, for twelve hours, then boil the whole down to one pint, strain, and give a wine- glassful every two hours, until the whole is taken. It commonly occa- sions several stools, an increased flow of urine, or nausea and vomiting, owing, it is supposed, to the agitation into which the worm is thrown from its presence. Sometimes joints of the worm begin to come away in less than an hour after the last dose. But often the doses must be repeated several successive mornings before they take effect, and it is right to repeat them occasionally for four or five days after the joints have ceased to come away. Laxatives should be administered from time to time. It is said to act with the greatest certainty when the joints of the worm come away naturally. The dose of the rind or flowers in powder, is from one to two scruples, and in decoction from one to three fluidounces. The seeds are demulcent. Off. Prep.—Decoctum Granati Radicis. Pycnanthemum Pilosum — Pyrethrum Parthenium. 785 PYCNANTHEMUM PILOSUM. Pycnanthemum. Nat. Ord.—Lamiaceaa, or Labiataj. Sex. Syst.—Didynamia Monogynia. THE PLANT. Description.—This is an indigenous perennial plant, with long and soft whitish hairs, and a subsimple stem, growing from one to two feet in hight. The leaves are sessile, nearly entire, lanceolate, acute at both ends, and pilose beneath ; the floral ones not whitened. The flowers are white, and disposed in large, terminal, sessile heads. The calyx-teeth are ovate-lanceolate, acute, and with the lanceolate bracts, are canes- cently villous and awnless. The corolla is pubescent, and the stamens exserted. History.—This plant is found in low grounds, dry hills and plains, from Ohio and Illinois extending southward, and flowering in July and August. The whole plant is used and yields its virtues to boiling water; it has the taste and odor peculiar to the Mint family. There are several species of this genus which possess similar medicinal properties, as the Pycnanthemum Virginicum, Narrow-leaf Virginian Thyme or Prairie- Hyssop, a pubescent plant with white flowers, sessile, lance-linear, entire, and punctate leaves, terminal and corymbed heads, and acuminate bracts. Also the P. Aristalum, or Wild Basil, with lance-ovate, subserrate, pubescent, acuminate, and short petiolate leaves ; with hirsute, terminal, capitate and subterminal verticils; bracts lance-subulate, and with the calyx terminated by awns. Likewise P. Incanum, and others. Properties and Uses.—Pycnanthemum is diaphoretic, stimulant, anti- spasmodic, carminative, and tonic. A warm infusion is very useful in puerperal, remittent, and other forms of fever, coughs, colds, catarrhs, etc., and is of much benefit in spasmodic diseases, especially colic, cramp of the stomach, and spasms of infants. The cold infusion is a good tonic and stimulant during convalescence from exhausting diseases. Dose of the infusion, either warm or cold, from one to four fluidounces, three or more times a day. Off.

Description. — Feverfew is a perennial, herbaceous plant, with a tapering root, and an erect, branched, leafy, round, furrowed stem, about two feet high. The leaves are alternate, petiolate, flat, bi- pinnate or tripinnate, of a hoary green, with the segments or leaflets 50 786 Materia Medica. inclining to ovate, decurrent, gashed and dentate. The flowers are white and compound. The panicle corymbose, sometimes compound; the peduncles long, naked, single-flowered, swelling upward. Flower- heads erect, about half an inch broad, with a convex yellow disk, and numerous short, broad, abrupt, two-ribbed, white rays ; often wanting ; sometimes multiplied, and the disk being obliterated, constitutes a double flower. Involucre hemispherical, imbricate, pubescent, with the scales scarious at the edge ; receptacle flat or convex, naked; achenia wingless, angular, uniform, crowned by a coroneted pappus which is usually toothed, and occasionally auriculate. History.—This is a European plant, and is common to the United States, found occasionally in a wild state, but is generally cultivated in gardens, and flowers in June and July. It is the Matricaria Parthenium of Linnaeus, and the Chrysanthemum Parthenium of Persoon. It imparts its virtues to water, but much better to alcohol. Properties and Uses.—Tonic, carminative, emmenagogue, vermifuge, and stimulant. The warm infusion is an excellent remedy in recent colds, flatulency, worms, irregular menstruation, hysteria, suppression of the urine, and in some febrile diseases. In hysteria, or flatulency, one teaspoonful of the compound spirits of lavender forms a valuable addition to the dose of the infusion, which is from two to four fluid- ounces. The cold infusion or extract, makes a valuable tonic. The leaves in poultice are an excellent local application in severe pain or swelling of the bowels, etc. Off. Prep.—Infusum Pyrethri.

Stamens ten, ascending; filaments awl-shaped, naked ; anthers large, pendulous; stigmas exserted beyond the ring; style declining and curved, longer than the petals. Capsule five-celled, five- valved, opening at the angles, many-seeded. History.—This plant is common in damp and shady woods, through- out various parts of the United States, bearing numerous white flowers in June and July. The whole plant is used, and imparts its medical properties to water. It has not been analyzed. Properties and Uses.—Round-leaved Pyrola is tonic, astringent, diu- retic, and antispasmodic. Used in decoction, both internally and exter- nally in various cutaneous eruptions, likewise in a carcinomatous or scrofulous taint of the system, and in leucorrhea, and some uterine dis- eases. As a local application it will be found of service in sore-throat, and ulcerations of the mouth, indolent ulcers, ophthalmia, etc., and forms an excellent soothing poultice for boils, carbuncles, and all painful tumors or swellings. The decoction, taken internally, is said to be valu- able in many urinary affections, as gravel, hematuria, and ulceration of the bladder, and in some nervous diseases. The decoction and extract have been used with success in convulsions, and form a large portion of a popular nostrum for epilepsy. Dose of the decoction, one or two fluid- ounces, three or four times a day ; of the extract, from two to five grains. Off. Prep.—Decoctum Pyrolae Rotundifoliae. PYRUS MALUS. The Apple-tree. Nat. Ord.—Rosacea?; Suborder, Pomese. Sex. Syst.—Icosandria Pentagynia. THE BARK. Description.—This is a well known tree, growing from twenty to forty feet high, with rigid, crooked, spreading branches, and a rough, blackish bark. The leaves are from two to three inches long, and about two- thirds as wide, ovate, or oblong-ovate, serrate, acute, or short-acumi- nate, pubescent above, tomentose beneath, and on petioles from half an inch to an inch in length. The fiowers are large, fragrant, expanding with the leaves, pale-rose color, and arranged in subumbellate corymbs. The calyx-tube is urn-shaped, limb five-cleft; pedicels and calyx villous- tomentose. Petals five, roundish, or obovate, with short claws. Stamens numerous; styles five, united and villose at base. Fruit or pome globose. History.—The Apple Tree is a native of Europe, naturalized in this country, and flowers from April to June. There are, probably, nearly 788 Materia Medica. one thousand varieties cultivated in the United States, and all of which are said to be derived from the Wild Crab. From the fruit, cider is manufactured, and both the fruit and its cider are much used for domes- tic and medicinal purposes. The bark is bitter and has been employed in medicine, it contains a principle called Phloridzin; the root-bark is the most active, and yields its virtues to boiling water. Phloridzin was discovered by Dr. Konink, a German physician, who found it to exist in the bark of the apple, pear, cherry, and plum trees, but in greater abundance in the fresh root-bark. To obtain it, the bark of the recent roots is boiled with water sufficient to cover them, for about an hour; the fluid is poured off, and as much more poured in for a second boiling. The decoctions are placed in a clean vessel, and set aside to remain undisturbed for about twenty-four hours, at the end of which time will be found a copious precipitate of phloridzin, of a deep- red, velvety-looking color. To remove the color, and render the article white, it is to be boiled with distilled water and animal charcoal, and then filtered ; this process is to be repeated two or three times, and then by allowing the solution to cool slowly, the phloridzin is deposited in the crystalline state. By evaporating the decoction, (after the above pre- cipitate has been collected,) to about one-fifth of its bulk, an additional quantity of phloridzin may be obtained, on allowing it to cool. It is light, white, crystallizable in silky needles, of a bitter taste, soluble in alcohol and boiling water, scarcely soluble in cold water or ether, and dissolved without change by alkaline solutions, and especially by ammo- nia ; heated to 212° it is deprived of its water of crystallization, and at a higher temperature it is fusible. It is without acid or alkaline reac- tion, and consists of carbon, hydrogen and oxygen. Properties and Uses.—Apple Tree Bark is tonic and febrifuge, and a decoction of it has been used with advantage in intermittent, remittent, and bilious fevers, and in convalescence from exhausting diseases. It may be given in doses of from one to four fluidounces, three times a day. A strong decoction or syrup of the Sweet-apple tree bark has been employed with success in some cases of gravel. The fruit or apple con- tains both malic and acetic acids, has a pleasant and refreshing flavor, and is a useful and healthy article of diet. However, it should not be eaten by dyspeptics, or patients afflicted with gout, rheumatism, or renal and cutaneous diseases. When baked, stewed, or roasted, it becomes valuable as an agreeable and healthy diet in febrile diseases, exan- thema, etc., and is more easily digested than when raw; it also becomes slightly laxative and is beneficial in cases of habitual constipation. Raw apples should always be well masticated before being swallowed, as otherwise, they may become a source of serious difficulties, especially with children. An apple tea may be made for fever patients, by boiling a tart apple in half a pint of water, and sweetening with sugar. Quercus Alba. 789 Cider forms not only a refreshing and agreeable drink for patients with fever, but actually exerts a salutary medicinal influence, especially where the tongue is coated brown or black. This is an Eclectic agent, which has recently become adopted by Allopaths in this class of dis- eases, and it is truly amusing to observe how much trouble they take to persecute and misrepresent us, while at the same time they are very eager to seize upon all our valuable remedial means. It is well known that cider in which horseradish, etc., has been steeped, has long been an Eclectic agent in the treatment of dropsy,—at this day its value is recog- nized by Allopathy, as may be seen in " Wood's Practice," under the treatment of dropsy. Nor is this the only agent they have derived from Eclecticism, without giving fair and honorable credit. Cooked apples form an excellent local application in ophthalmic inflammation, erysipe- latous inflammation, sore and swelled throat in scarlatina, ulcers, etc. Phloridzin is tonic and febrifuge, and in the dose of from ten to fifteen grains has cured intermittent fever where quinia has failed; unlike quinia it does not induce gastralgia. QUERCUS ALBA. White Oak. Nat. Ord. — Corylacea?, Lindley; Amentaceae, Jussieu; Cupuliferaa, Bichard. Sex. Syst.—Monoecia Polyandria. THE BARK. Description.—Quercus Alba is a forest tree, varying in size according to the climate and soil, attaining the hight of from sixty to ninety feet, with a diameter of from three to six feet. Its trunk and large branches are covered with a whitish bark, which serves to distinguish it from most of the other species. The leaves are oblong, pinnatifid, sinuate, smooth, bright-green above, pale or glaucous beneath, and regularly and obliquely divided into from three to five lobes, which are oblong, or linear, obtuse, mostly entire, and sometimes narrowed at their base. The fiowers are monoecious and amentaceous. The cup is hemispheri- cal, naked, much shorter than the acorn, deep, tuberculate. The acorns are large, ovate, coriaceous, one-celled, one-seeded, surrounded at base by the cup, and supported singly or in pairs upon peduncles nearly an inch in length. Quercus Rubra, or Red Oak, is a lofty, wide-spreading tree, attain- ing the hight of about seventy feet, with a diameter of three or four feet. The leaves are from six to ten inches in length, on long petioles, oblong, smooth on both sides, pale beneath, obtusely sinuate, with short, and entire or sparingly dentate, mucronate lobes, from four to six on each side. The fructification is biennial. The acorns are oblong-ovoid, about an inch long, surrounded at base by a saucer-shaped, shallow, even cup, very much shorter than the acorn, of very small and close scales, and subsessile. 790 Materia Medica. Quercus Tinctoria, Quercitron or Black Oak, is one of the loftiest trees in the forest, frequently attaining the hight of from eighty to one hundred feet, with a diameter of four or five feet. The bark is deeply furrowed, black or deep-brown. The leaves are from six to eight inches long, obovate, oblong, more or less rusty-pubescent beneath, finally glabrous, slightly or sometimes deeply sinuate-lobed, with oblong, obtuse, mucronate, somewhat toothed lobes. The acorns are brown, nearly spherical or depressed-globose, about one-half immersed in a deep, thick, flat, conspicuously scaly cup, which is subsessile. The leaves turn dark- red after frost. History.—Quercus is a very large and important genus, consisting of many species, a large proportion of which grow in the United States. Their general character is that of astringents, and the three above described, are those which have been more particularly employed in medicine. The bark of the trees is the officinal portion. White Oak grows throughout the Union, but is more abundant in the Middle States. Its wood is strong and durable, and is extensively em- ployed in ship-building, coopering, carriage-making, etc. The bark is sometimes employed for tanning, but for this purpose, that o( the Red, and Spanish Oaks are preferred; its principal use is in medicine. It should be deprived of its epidermis, which contains no astringent property; it then presents a coarse fibrous texture, is tough and not easily pulve- rized, of a light yellowish-brown color, a feeble odor, and a strongly astringent, bitterish taste. Its active properties are extracted by water or alcohol. It contains a large proportion of tannin, some gallic acid, and extractive matter. The inner bark, collected during the spring, is said to afford the most tannin. A bitter principle has been obtained from the European oak-bark (Quercus Pedunculata), called Quercin. Our own oak-bark is fully equal in medicinal virtues to the foreign, and may, undoubtedly, be substituted for this in obtaining quercin. The bark must be boiled with water acidulated with one-hundredth of sulphuric acid, after which the sulphuric acid is to be removed by the addition of sufficient milk of lime, and then a solution of carbonate of potassa must be added so long as it causes a white precipitate; filter the liquor, evaporate to the con- sistence of a thin extract, add alcohol, and finally evaporate the spiritu- ous solution down to a small volume, and let it stand for some days; yellow crystals will form, which may be obtained colorless by repeated crystallizations. Thus prepared, quercin is in small white crystals, ino- dorous, very bitter, soluble in water, less so in alcohol containing water, insoluble in absolute alcohol, ether, or oil of turpentine, and is neutral. Black Oak is likewise a forest tree common to the United States, the bark of which is much used in tanning, and for dyeing. It is more bitter than the other species named, and when chewed stains the saliva yellow. It is seldom employed internally on account of its disposition Quercus Alba. 791 to irritate the bowels, but is valuable as an external astringent. Boiling water extracts a coloring principle from its cellular integument, of a brownish-yellow color, which is deepened by alkalies and rendered brighter by acids. This bark, deprived of its epidermis and powdered, is exported to Europe under the name of Quercitron, where it is exten- sively used for dyeing silk and wool of a yellow color. The coloring principle, called Quercitrin or Quercitric Acid, may be obtained by add- ing gelatin to a decoction of the bark, which precipitates the tannic acid, filtering the liquor, adding a very small quantity of hydrated oxide of lead, which produces a brown precipitate, pouring off the golden-yellow liquid left, precipitating again with an additional quantity of the hydrate, and decomposing the resulting quercitrate of lead by hydrosulphuric acid. Filter the colorless liquid left, evaporate in vacuo, and white needle- shaped crystals of pure quercitrin will be obtained, which has the pro- perty of combining with salifiable bases. Black oak bark contains more tannic and gallic acids than the other officinal species. Red Oak is more common in the Northern States and Canada; its wood is reddish and coarse-grained, and used principally for fuel; its bark is extensively used in tanning. It contains considerable tannin, and is generally employed as an external agent. An extract of the bark, as well as the potash obtained from its ashes, are both much employed as a local application in the treatment of cancer, indolent ulcers, etc. Properties and Uses.—Oak bark is somewhat tonic, powerfully astrin- gent, and antiseptic. Used with advantage in intermittent fever, obsti- nate chronic diarrhea, chronic mucous discharges, and in certain forms of passive hemorrhages; likewise in phthisis, and diseases attended with great prostration, colliquative sweats, etc. In such cases, a decoction of it may be combined with lime-water. Externally, a decoction forms an excellent gargle for relaxed uvula and sore-throat, a good stimulating astringent lotion for ulcers with spongy granulations, and an astringent injection for leucorrhea, prolapsus ani, hemorrhoids, etc. A poultice of the ground bark has often proved of service in gangrene and mortifica- tion. In sickly, debilitated children, and in severe diarrheas, especially when the result of fevers, the decoction given internally, and used as a bath to the body and limbs, two or three times a day, will be found very efficacious. When given for diarrhea or dysentery, it should be com- bined with aromatics, and sometimes with castor oil. A bath is often advantageous in some cutaneous diseases. The green bark of elder and white oak, bruised together, or in strong decoction, forms a very useful and valuable application to abrasions. Dose of the decoction, one or two fluidounces; of the extract, from five to twenty grains. A coffee made from roasted acorns, has been highly recommended in the treat- ment of scrofula. Off.

These are pro- duced by the puncture of the shoots and young boughs by a hymenope- terous insect or fly, for the deposition of its eggs. This insect is the Cynips Quercusfolii of Linnaeus, and the Diplolepis Gallce-tinctorice of Geoffroy; it has a fawn-colored body, dark antennae, and the' upper part of its abdomen a shining brown. After the puncture is made, the egg is deposited in the wound, and in consequence of the irritation thus produced, a morbid secretion takes place, which concreting as it flows, forms the hard excrescences called Galls. The egg grows with the gall, is converted into a larva, which feeds upon the morbid excrescence sur- rounding it, and forms a cavity in its center. Toward the end of July, the young insect, having passed through all its stages of transformation into the state of a fly, eats its way out and escapes. The best galls are those which are gathered about the middle of July, when they have attained their full size, and just before the escape of the insect. They are then called green, blue, or black galls; those which are gathered later, after having been injured by the insect, are usually larger, less heavy and compact, and lighter-colored than the former — they are termed White galls, and are of an inferior quality. Galls are imported from the Mediterranean ports, especially Smyrna and Trieste, or from London. The best kind were formerly called Aleppo Galls, from a supposition that they were obtained more abun- dantly in the vicinity of that city, but at present, it is hard to discrimi- nate between the finer sorts from various places. An excellent article has been brought from Calcutta, of equal value with that from the Mediterranean. Galls vary in size from that of a large pea to that of a small walnut; they are roundish, tuberculated on the surface, and hollow within. The best are of middle size, dark-bluish or lead color, sometimes with a greenish tinge, whitish or brownish internally, hard, heavy, brittle, with a flinty fracture, a striated texture, and a small Quercus Infectoria. 793 cavity in the center, containing dust, the undeveloped insect, or the insect itself in the state of larva, pupa, or of fly. It forms a light yellowish-gray powder. The inferior sorts are of a lighter color, some- times reddish or nearly white, of a loose texture, with a large cavity in the center, from which a small hole or perforation passes to the external surface, and through which the fly effected its escape. Both kinds are brittle, easily pulverized, inodorous, and have an intensely astringent taste. Water is the best solvent of galls, and proof-spirit the next; pure alcohol or ether acts more feebly upon them. All the soluble matter of galls is taken up by forty times their weight of boiling water, and the residue is tasteless ; alcohol dissolves seven parts in ten, ether five parts. Upon cooling, a saturated decoction deposits a copious pale-yellow precipitate. An infusion or tincture of galls affords precipitates with muriatic, sulphuric, nitric, phosphoric, and arsenic acids, lime-water, carbonate of ammonia, carbonate of potassa, solutions of acetate and subacetate of lead, sulphates of iron and copper, nitrates of silver and mercury, tartrate of antimony and potassa, gelatin, infusions of Peruvian bark, Colombo, opium, and many other vegetables, especially those con- taining proximate alkaline principles, with most of which tannic acid forms insoluble compounds. The infusion of galls reddens litmus paper, and is rendered orange by nitric acid, milky by corrosive sublimate, and its own color is deepened by ammonia. Galls consist of a large proportion of tannic acid ; according to Davy 500 parts give 185 parts of matter soluble in water, of which 130 were tannic acid, 31 gallic acid with a little extractive, 12 mucilage and matter rendered insoluble by evaporation, and 12 saline matter and calcareous earth. Guibourt found galls to consist of 65 per cent, of tannic acid, 10.5 of lignin, 11.5 of moisture, 5.8 of gum, sugar and starch, 4.0 of gallic, ellagic, and luteo- gallic acids, beside extractive, chlorophylle, volatile oil, albumen and salts. The gallic and ellagic acids, according to M. Pelouze, do not pre- exist in the galls, but are formed by the action of atmospheric oxygen upon their tannin. I have in my possession a specimen of an excrescence found on a plant, the name of which has not been ascertained, growing in Texas, in the neighborhood of Red river. It was presented to me by Mr. W. S. Merrell; he obtained it from a physician who had pursued the prac- tice of his profession in that section of country, and who states that it is caused by the puncture of some insect, and is found in abundance. According to his account these morbid growths are hollow, globose, and whitish. The dried specimens which I have are of a light brown color mixed with fragments of a darker color, and appear to be pieces of a hollow body, some of which very much resemble squill in color. They are half a line and less in thickness, of various sizes, from a line to three-fourths of an inch in diameter, irregular in their shape, having an external convex surface which is very finely corrugated, and of a 794 Materia Medica. shining, resinous appearance under the microscope, and an internal concave surface which is much smoother that the external one, and in which may be distinctly traced veins running in various directions. They are translucent, with the exception of the darkest colored, have a short fracture, presenting under the microscope a shining, finely granu- lated, waxy or resinous surface, are inodorous, brittle, of a taste at first resembling green tea, but which becomes slightly bitter and powerfully astringent; the light-colored pieces are more astringent and bitter than the dark ones. One piece of this article, about one quarter of an inch in diameter was placed in an ounce of water and agitated for a few minutes, and was not dissolved; to this about five or six grains of sul- phate of iron were then added, which, on agitation, immediately turned the liquid black. This, used as an ink, formed pale lines scarcely discernible, but which, in a few minutes, became intensely black. I consider this the most powerful astringent vegetable product ever yet found in a natural state, and trust that means may be devised to intro- duce it into our markets. Properties and Uses.—Galls are astringent and may be used in all cases where astringents are indicated, as in chronic dysentery, diarrhea, passive hemorrhages, and in cases of poisoning by tartar-emetic or the vegetable alkaloids, in infusion or tincture. Boiled in milk they are good for the diarrhea of children. As a local application, the infusion is employed as an injection in gleet, leucorrhea, prolapsus ani, or for a gargle in indolent ulceration of the fauces, relaxed uvula, and the chronic stage of mercurial action on the mouth; the addition of alum is said to render it more beneficial. Dose of the powder, from five to twenty grains ; of the tincture half a fluidrachm to a fluidrachm; of the infusion from half a fluidounce to a fluidounce. Off.

Description. — Ranunculus Bulbosus has a perennial, solid, fleshy, roundish, depressed cormus or root, sending out radicles from its under side ; in autumn it gives off lateral bulbs near its top, which afford plants for the following year, while the old cormus decays. The root sends up annually, several erect, round, hairy, and branching stems, from six to eighteen inches in hight, and which are furrowed, hollow, and bulbous at base. The radical leaves are on long petioles, ternate, sometimes quinate; the segments variously cut, lobed and toothed, hairy. The cauline leaves are sessile and ternate, the upper ones more simple. Each Resina. 795 stem supports several solitary, golden-yellow flowers, upon furrowed, angular and hairy peduncles. The sepals are oblong, hairy, and reflexed against the peduncle. The petals are five, inversely cordate, longer than the sepals, and arranged so as to represent the shape of a small cup. At the inside of the claw of each petal is a small cavity, which is covered with a minute wedge-shaped emarginate scale. The stamens are numerous, yellow, with oblong, erect anthers. Ovaries numerous, with reflexed stigmas. Receptacles spherical. Carpels acute, naked, diverging, tipped with very short recurved beaks. History.—This plant is common to Europe and the United States, growing in fields and pastures, and flowering in May, June, and July. There are several species, possessing similar properties, and designated by the common name of Buttercup; among these the R. Acris, R. Repens, R. Sceleratus, and R. Flammula, may be indiscriminately sub- stituted, the one for the other. In all these species, the active principle depends upon a volatile, acrid principle, which is dissipated by drying, or by the application of heat, and which may be separated by distillation with water. The fresh plant or root, when chewed, excites violent irritation in the mouth and throat, inflaming and even excoriating the tongue, and inside of the cheeks and lips, if not quickly discharged ; and if swallowed, it produces much heat and pain in the stomach. The distilled water of R. Flammula is said to act as an instantaneous emetic. Properties and Uses.—From the caustic or acrid character of these plants they are seldom used internally; but when applied externally, are powerfully rubefacient and epispastic. The R. Bulbosus is the officinal plant. It is employed in its recent state, in rheumatic, neuralgic and other diseases where vesication and counter-irritation are indicated. Its action, however, is so uncertain, and sometimes so violent, causing deep and obstinate ulcers, that it is seldom used. It is sometimes used by the beggars of Europe to produce and keep open sores, for the purpose of exciting sympathy. I have cured two obstinate cases of nursing sore- mouth, made by adding two drachms of the recent root, cut into small pieces, to one pint of hot water ; when cold, a tablespoonful was given three or four times a day, and the mouth frequently washed with a much stronger infusion. RESINA. Resin or Rosin. History.—This is the residuum after the distillation of the volatile oil from the turpentine of the Pinus Palustris and other pines. When the distillation is not carried too far, the rosin contains a little water. This is the officinal article, the Resina Flava, or yellow rosin. If, when in a state of fusion, it be strongly agitated with water, it acquires a dis- tinct appearance, and is called Resina Alba, or white rosin. A more 796 Materia Medica. continued heat than that prepared in making the yellow rosin expels the water, and produces transparent rosin; and if the process be pushed as far as it can, without producing a complete alteration of properties, the residue acquires a deeper color, and is termed Brown or Black rosin, Fidler's rosin, Colophony. If melted rosin be run into cold water, con- tained in shallow tanks, and a supply of cold water be kept up until the rosin has solidified, a pale yellow product is obtained, called Flockton's Patent Rosin. Rosin is translucent, yellowish, brittle, pulverizable, rather heavier than water, of a feeble terebinthine odor and taste, fusi- ble at a moderate heat, inflammable, soluble in ether and many volatile oils, insoluble in water, partially soluble in boiling rectified spirit, and capable of uniting by fusion with wax, fixed oils, fats, and spermaceti. The concentrated acids dissolve it, especially with the aid of heat; sul- phuric or nitric acids slowly convert it into artificial tannin. Solutions of potassa and soda partially dissolve it, forming soluble soaps, and leaving a resinous principle undissolved. Prof. Olmstead states that rosin added to lard, gives it a degree of fluidity not before possessed by the lard, and also prevents the latter forming those acids which corrode metals. If three parts of lard have one part of finely powdered rosin added, and the mixture be well stirred, without the application of heat, it softens, and so nearly approaches a fluid as to run freely when taken up on the stirring-rod, at a temperature of 72°. On melting the mix- ture, and setting it aside to cool, the following changes take place: At 90° it remains transparent and limpid; at 87°, a pellicle begins to form on the surface, and soon after it begins to grow slightly viscid, and as the temperature descends, it passes through different degrees of vis- cidity, until at 76° it becomes a dense semifluid. A compound of one part of rosin to four of lard, may be used for various purposes: by add- ing a portion of black-lead, and applying a thin coating to iron stoves and grates, it prevents them from rusting, forming a complete protection. It may likewise be applied to various other purposes. Properties and Uses.—Rosin is seldom given internally. Its principal use is to form plasters and ointments, to which it is an excitant ingre- dient, and renders them more adhesive. The vapor from rosin has been inhaled in chronic bronchitis and affections of the lungs with benefit; and the fumes from burning rosin, if received upon the parts, will, it is said, remove the irritation attending piles and prolapsus ani. Half a drachm of powdered rosin dissolved in a sufficient quantity of chloro- form, so as to make a thick solution, will relieve neuralgia of the teeth, or toothache, by introducing a piece of cotton, which has been impreg- nated with the solution, into the hollow teeth.

Rhamnus Catharticus. 797 RHAMNUS CATHARTICUS. Buckthorn. Nat. Ord.—Rhamnaceas. Sex. Syst.—Pentandria Monogynia. the berries or fruit. Description.—Buckthorn is a shrub from six to fifteen feet in hight. The branches are alternate, or nearly opposite, spreading, straight, round, smooth, hard, and rigid, each terminating in a strong spine, after the first year. The leaves are from one to two inches long, and about two- thirds as wide, deciduous, bright-green, smooth, simple, entire, veined, ovate, serrate, and in fascicles, on short downy petioles; the young ones are downy; the earlier ones in tufts from the flowering buds, and the rest opposite, on the young branches. Stipules linear. The flowers are small, numerous, yellowish-green, on the last year's branches, and usu- ally dicecious or polygamous; the fertile flowers have the rudiments of stamens, narrow petals, and a deeply four-cleft style; the barren ones have an abortive ovary, and broader petals. The anthers are small, rounded, and borne on short, subulate filaments, which are inserted in the mouth of the calyx. The berries are globular, about the size of a pea, bluish- black, containing a green pulp, with four cells, and as many seeds, which are smooth, elliptical, convex on one side and flattened on the other. History.—Buckthorn is a native of Europe, and is found growing wild in some parts of the United States, flowering in May and June, and ripening its fruit in the latter part of September. The berries are the officinal portion. They are round, about the size of a pea, black, smooth and shining, somewhat flattened on the summit, with an unpleasant odor, and a bitter, acrid and nauseous taste. The juice of the berries stains paper green, is reddened by acids, and is rendered light-green by alkalies. On standing it ferments, acetic acid is formed, and it becomes red. A pigment, known as Sap-green, is made with them, by adding a little alum to the inspissated juice, or by adding lime-water and gum arabic to it, and evaporating to dryness. It contains green coloring matter, sugar, brown mucilage, and bitter extractive supposed to be its active princi- ple. The bark of Rhamnus Frangula, is occasionally used in Germany as a carthartic, under the name of Cortex Frangulm. Properties and Uses.—Buckthorn berries, (Rhamni Baccae) are pow- erfully cathartic ; twenty of the recent berries cause brisk watery purg- ing, with nausea, dryness of the throat, thirst, and tormina. These effects are partly removed by giving the juice (Rhamni Succus) in the form of syrup, and which formerly enjoyed much reputation as a hydragogue in gout, rheumatism, and dropsy; at present it is seldom employed in prac- tice, and is occasionally employed as an adjunct to other cathartic and diuretic mixtures. Dose of the syrup, from half a fluidounce to a fluid- ounce. 798 Materia Medica. RHEUM PALMATUM. Rhubarb. Nat. Ord.—Polygonaceae. Sex. Syst.—Enneandria Trigynia. the root. Description.—In relation to the Rhubarb root, the scientific world is in much ignorance, not knowing the exact plant or plants from which it is produced. All that is known is, that it is the root of one or more species of rheum, supposed to be the Rheum Palmatum and R. Undu- latum. The species from which the medicinal drug is obtained inhabit the great plains of Tartary, the steppes of Siberia, and the great ranges of mountains lying between these and the northern parts of India, and great caution is exhibited in monopolizing the trade in the article. Until 1732 but little was known as to the true origin of rhubarb; but at that time Jussieu and Rand received specimens from Russia which were named Rheum Rhabarbarum by Linnaeus, under an impression that they were of the species which furnished the genuine drug; this name has since been changed to Rheum Undulatum. Subsequently Kauw Boerhaave obtained some seeds of a plant said to produce the root, and which upon planting yielded two distinct species, the R. Undulatum and R. Palmatum. Several other species have from time to time attracted the attention of naturalists, being reputed each as the one which fur nished the genuine rhubarb of commerce, but the presumption is, that it is derived from several species of Rheum, and that the differences of character existing between the cultivated European and Asiatic roots are owing to the differences in soil, climate, mode of cultivation, etc. The rhubarb plants are herbaceous, perennial, with large branching roots, vigorous stems from four to eight feet high, with numerous, large, petiolate leaves at base, and terminating in branching panicles of numer- ous, small flowers. The leafstalks of the various species have a pleasant acid taste, and several of them are cultivated in the United States for the purpose of making pies and tarts, as the R. Rhaponticum, R. Hy- bridum, and R. Compactum. The method of cultivation and preparation of rhubarb in its native country is not satisfactorily known, though vari- ous statements in relation to it have been published. Lindley, in his Flora Medica, gives the following description of the plants which furnish rhubarb:— Rheum Palmatum. Willd. Sp. Plant, ii. 489; Lindley, Flor. Med. p. 358 ; Carson, Must, of Med. Bot. ii. 22, pi. 69. "Leaves roundish-cordate, half palmate ; the lobes pinnatifid, acuminate, deep dull-green, not wavy, but uneven and very much wrinkled on the upper side, hardly scabrous at the edge, minutely downy on the under side ; sinus completely closed; the lobes of the leaf standing forward beyond it. Petiole pale green, marked with short purple lines, terete, obscurely channeled quite at the Rheum Palmatum. 799 upper end. Flowering stems taller than those of any other species." This species is said to inhabit China in the vicinity of the great wall. It has been cultivated in England and France, for the sake of its root, which is generally admitted to approach more nearly in odor, taste, and the arrangement of its colors, to the Asiatic rhubarb than that of any other known species. R. Undulatum. Willd. Sp. Plant, ii. 489 ; Lindley, Flor. Med. p. 357; Woodv. Med. Bot. 3d ed. v. 81. " Leaves oval, obtuse, extremely wavy, deep-green, with veins purple at the base, often shorter than the petiole, distinctly and copiously downy on each side, looking as if frosted when young, scabrous at the edge ; sinus open, wedge-shaped, with the lower lobes of the leaves turned upward. Petiole downy, blood-red, semicylindrical, with elevated edges to the upper side, which is narrower at the upper than the lower end." This is a native of Siberia, and probably of Tartary and China. It was cultivated by the Russian gov- ernment as the true rhubarb plant; but theculture has been abandoned. It contributes to the rhubarb produced in France. R. Compactum. Willd. Sp. Plant, ii. 489 ; Lindley, Flor. Med. p. 358; Carson, lllust. of Med. Bot. ii. 24, pi. 71. " Leaves heart-shaped, obtuse, very wavy, deep-green, of a thick texture, scabrous at the mar- gin, quite smooth on both sides, glossy and even on the upper side; sinus nearly closed by the parenchyma. Petiole green, hardly tinged with red except at the base, semicylindrical, a little compressed at the sides, with the upper side broad, flat, bordered by elevated edges, and of equal breadth at each end." This plant is said to be a native of Tar- tary and China. It is one of the garden rhubarbs, and is cultivated in France for its root. R. Australe. Don, Prod. Flor. Nepal, p. 75.—R. Emodi. Wallich ; Lindley, Flor. Med. p. 354 ; Carson, lllust. of Med. Bot. ii. 24, pi. 70. " Leaves cordate, acute, dull-green, but little wavy, flattish, very much wrinkled, distinctly rough, with coarse short hairs on each side ; sinus of the base distinctly open, not wedge-shaped but diverging at an obtuse angle, with the lobes nearly turned upward. Petioles very rough, rounded-angular, furrowed; with the upper side depressed, bordered by an elevated edge, and very much narrower at the upper than the lower end." The root of this species was at one time conjectured to be the source of officinal Asiatic rhubarb ; but has been found to have scarcely any resemblance to it. The plant has been cultivated both in Europe and this country, and its petioles answer well for tarts, etc. R. Rhaponticum. Willd. Sp. Plant, ii. 488 ; Lindley, Flor. Med. p. 357 ; Loudon's Encyc. of Plants, p. 335. " Leaves roundish-ovate, cordate, obtuse, pale-green, but little wavy, very concave, even, very slightly downy on the under side, especially near the edge, and on the 800 Materia Medica. edge itself; scabrous at the margin ; sinus quite open, large, and cuneate. Petiole depressed, channeled on the upper side, with the edges regularly rounded off, pale green, striated, scarcely scabrous. Panicles very com- pact and short, always rounded at the ends, and never lax as in the other garden species. Flowering stem about three feet high." The Rhapontic rhubarb grows upon the banks of the Caspian Sea, in the deserts between the Wolga and the Oural, and in Siberia. It is said also to grow upon the borders of the Euxine. It is cultivated as a gar- den plant in Europe and this country; and large quantities of the root are produced for sale in France. It is said by Royle to be the source of the English rhubarb. — U. S. Disp. Beside the above species, several others have been named, as the R. Cuspicum from the Altai mountains, R. Leucorrhizum from the Tar- tarian Kirghese desert, R. Speciforme, R. Webbianum, and R. Moor- craftianum, growing on the Himalaya mountains, R. Crassinervium, R. Hybridum, etc. History.—Among the several kinds of rhubarb found in commerce that called Russian rhubarb, is considered the best. It was formerly derived from the Turkish ports, and in consequence received the name of Turkey Rhubarb; and has likewise been called by the several names of Persian, Moscow, Bucharian, or Siberian Rhubarb. It is prepared in Tartarv, from which place it is conveyed to a town of Kiachta where it undergoes a rigid inspection by an apothecary appointed by the Russian government, who burns the inferior pieces, and forwards the remainder to St. Petersburg, where it is again sorted and shipped for other countries. It is in irregular, roundish cylindrical or flat plano-convex pieces, usually from one to three inches in breadth, always obscurely angular, owing to the bark of the root together with a small portion of the substance immediately beneath the bark, having been apparently sliced off longitudinally with a knife, and with large perforations, frequently extend- ing only to the center, and evidently made to ascertain the soundness of the article at the time of inspection. Their external surface is yellow, and thinly covered with a yellow powder, caused probably by the friction or rub- bing together of the pieces; and when scratched with a knife, they give a bright yellow streak. They have rather a compact texture, an uneven fracture exposing a surface beautifully marbled with irregular, waving, grayish and reddish veins. They are easily pulverizable, giving a bright yellow powder. Russian rhubarb has a peculiar, aromatic, bitter, faintly astringent taste, and a strong, peculiar odor; it tinges the saliva yellow, and produces a crackling, or sense of grittiness between the teeth, owing to crystals of oxalate of lime, which are largely contained in it. These crystals may be seen under the microscope by previously boiling thin slices of the root in water until soft, and then crushing and agitating them in the water; in 100 grains Mr. Quekett found between 35 and 40 grains of these minute crystals. Rheum Palmatum. 801 The Chinese or East Indian Rhubarb is brought from Canton; the finest quality of it, termed Batavian or Dutch-trimmed Rhubarb, very much resembles the Russian Rhubarb in appearance. That which is brought to this country, however, as Chinese Rhubarb, consists of irregular cylindrical or roundish pieces, sometimes flattened on one or both sides, and never angular, like Russian or Dutch-trimmed Rhubarb, of a duller yellow color than the former variety, and presenting an external appearance as if the bark had been removed by scraping or rasping, and the surface rendered smooth and somewhat powdery by attrition. Their density is somewhat greater than that of Russian Rhubarb, and their texture more compact; but the appearance of a fresh fracture is very nearly the same. They are usually perforated, and the holes frequently contain fragments of cord by which they were suspended during the drying process. They are not of such uniform quality as the Russian article, being often imperfectly stripped of their bark, and more or less attacked by insects, moldiness, or other impurity. The color, odor, taste and grittiness are very nearly, if not precisely the same as those of the Russian drug. Their powder is yellow, with a reddish-brown tinge, but in the finer kind it is hardly discernible from the powder of Russian Rhubarb. The major portion of the rhubarb consumed in this country is the Chinese variety; it is somewhat inferior to the Russian, but is less expensive, and when of good quality is suffi- ciently active to answer all medical purposes. European Rhubarb is obtained from England, France, Belgium, and Germany. That which is imported into this country comes principally from England and France. English Rhubarb is obtained from the roots of Rheum Rhaponticum, which is cultivated in various parts of the country, but chiefly in Oxfordshire near Banbury. It is collected in October and November from plants three or four years old. The pieces, as seen in this country, are of various shape and size, sometimes cut and perforated to resemble the Russian, frequently cylindrical, five or six inches long, by an inch or less in thickness, more commonly flat, or somewhat lenti- cular, and quite large. It has an external reddish hue, and brownish spots of adhering bark, and internally a looser, softer, and more spongy texture than the others, with occasional cavities, especially in the center. It is more easily scratched with the nail, and yields a lighter yellow streak; and the surface of a fresh fracture shows the same marbled red and gray lines, but generally more straightly radiated from the center. It has a mucilaginous, astringent taste, with little bitterness and a flavor similar to Eastern Rhubarb, but much more feeble in odor, more muci- laginous, and without any grittiness between the teeth. The long or inferior pieces are often met with in this country, and are called Stick- rhubarb in England. These are principally used for adulterating the finer Eastern varieties, when in powder. 51 802 Materia Medica. French Rhubarb, also called Rhapontic Rhubarb, or Krimea Rhubarb, is made in abundance at an establishment called Rheumpole, near the port of L'Orient, from the roots of Rheum Rhaponticum, R. Undulatum, and R. Compactum. It bears some resemblance externally to Chinese Rhubarb, but has neither its odor, nor aromatic taste. Its properties are very similar to the English variety, and like that, it is often used to adulterate the powder of true eastern rhubarb. A mere reference to other varieties of rhubarb will be sufficient here. The Himalaya or Emodi Rhubarb, from the Rheum Astrale, and other species growing in the Himalaya mountains, is brown, fibrous, inodor- ous, and inferior, yet is said to be nearly as active as the Chinese. The Russian traveler, Pallas, describes a White or Imperial Rhubarb as being a superior article, of white color, and sweetish taste; but according to Dr. G. Walpers, who has made some inquiries in relation to it, it proves to be one of those fabulous sayings, in which, unfortunately, some travelers are very apt to indulge. Good rhubarb may generally be known by being of a lively color, mode- rately compact and heavy, of an aromatic odor, of a bitter and astring- ent, not mucilaginous taste, and by feeling gritty, and staining the saliva bright yellow; it should be brittle, presenting a marbled appear- ance of reddish and yellowish veins intermingled "with white, when freshly broken, and affording a bright yellow powder, perhaps with a slight reddish-brown tinge. When very compact and heavy it is infe- rior; when very light it maybe rotten or worm-eaten. Inferior rhubarb is often colored with turmeric, which may be detected by solution of boracic acid, which turns turmeric-yellow to brown, but does not affect the yellow color of the true rhubarb. When in powder, the adultera- tions of rhubarb are very difficult, if it all possible, to detect. Water, either cold or boiling, extracts the active properties of rhubarb, and the infusion is of a dark reddish-yellow color, with the peculiar odor and taste of rhubarb; and the residue becomes whitish, tasteless and in- odorous. Long boiling impairs its virtues. The infusion prepared by percolation with cold water, is preferable to that obtained with boiling water alone, as this last becomes turbid on cooling, owing to a partial separation of some of the principles of the root; this may be prevented, however, by the addhion of a little spirit. Proof spirit is a more ready solvent of the active ingredients of rhubarb than water. Nitric acid added to an infusion of Russian rhubarb in twenty parts of water, causes a dense muddiness, and slowly a yellow precipitate, owing to the sepa- ration of rhabarbarin; tincture of iodine causes a tawny muddiness, probably for a similar reason; solution of potassa combines with the rha- barbeiin and produces a fine blood-red color; and lime-water causes at first a pale cherry-red haze, which slowly gives place to a red precipi- tate composed of rhabarberin and lime. Sesquichloride of iron pro- Rheum Plamatum. 803 duces a green precipitate, and solution of isinglass a yellow curdy deposit, owing to the presence of tannin. Chinese Rhubarb is affected in the same way by the above reagents. Rhubarb has been analyzed by several chemists, and with various results. In 1836 Brandes found the Eastern drug to consist of 2 per cent, of pure rhabarbaric acid or rhabarbarin, 7.5 of the same acid impure, 2.5 of gallic acid, 9 of tannin, 4 starch, 11 of uncrystallizable sugar in union with tannin, 14.4 of gummy extractive, 3.5 of coloring extractive, 4 of pectic acid, 11 of oxalate of lime, 1.1 of malate and gallate of lime, 1. 5 of sulphate of potassa and chloride of potassium, 1 of silica, 0.5 of phosphate of lime and oxide of iron, 25 of lignin, and 2 of moisture. The principles indi- cated by previous investigators, under the names Rhein, Rheumin, Rha- barbarin, and Caphopicrite, appear to be complex bodies, consisting of the Rhabarbaric acid of Brandes combined with other principles. It may be obtained by purifying the alcoholic extract of rhubarb with cold water, drying the residue, dissolving it in the smallest possible bulk of spirit, and then adding ether so long as it separates anything. The ether is then to be distilled off, and the residue again similarly treated with spirit and ether. The solution yields it pure by sponta- neous evaporation. It is granular, yellow, tasteless and inodorous, fusible, partially volatile, sparingly soluble in water, more so in alcohol or ether, and acid in its reactions. Alkaline solutions dissolve it form- ing intensely red solutions, from which acids separate it as a yellow precipitate, and which, with the earthy salts, give yellow precipitates of the principle, united with an earthy base. Ultimate analysis shows that it is identical with a coloring matter (chrysophanic acid) obtained by Rochleder from the yellow lichen Parmelia Parietina. Schlossberger and Dcepping, in a recent and elaborate analysis, have, in addition to the above principles, also discovered three coloring princi- ples, which are freely soluble in alcohol, slightly soluble in water, and hold an intermediate place betwen resin and extractive matter. Two of these were uncrystallizable, one of which was brown and the other red, and were named Phceoretin and Erythroretin ; the other formed in granular crystals, and was named Chrysophanic acid. Aporetin was the name given to another resinous substance, which was insoluble in the alcohol from which it had been precipitated by ether, and isomeric with phaeoretin, it was supposed to be a product of the operation. These three principles were obtained by pursuing the above-named process for rhabarbaric acid, and dissolving the yellow precipitate, had by evapora- tion, in alcohol ; the insoluble portion is aporetin, and the phceoretin is taken up by the alcohol, from which it may be separated by evapora- tion. It is a yellowish-brown powder, very slightly soluble in water or ether, freely soluble in alcohol and alkaline solutions, with which it pro- duces an intense reddish-brown color, and which is precipitated yellow by the mineral acids. The ethereal solution of the alcoholic extract, 804 Materia Medica. after all the aporetin and phaeoretin had been separated was allowed to separate spontaneously, and a large quantity of beautiful yellow crys- talline granules of chrysophanic acid was obtained, possessing properties the same as named above for rhabarbaric acid. When the deposition of these granules ceased, the ethereal solution was evaporated, which yielded the red resin or erythroretin, and which formed beautiful purple combinations with potassa or ammonia. The cathartic principle of rhubarb has not yet been isolated, and is supposed to be more or less volatile. The incompatible substances with an infusion of rhubarb, are gelatin, most of the acids, the salts of sesquioxide of iron, acetate of lead, nitrate of protoxide of mercury, nitrate of silver, protochloride of tin, lime-water, solutions of quinia, tartar emetic, sulphate of zinc, corrosive sublimate, etc. Properties and Uses.—Rhubarb is cathartic, astringent and tonic; as a cathartic, it acts by increasing the muscular action of the intestines, rather than by augmenting their secretions, and affects the whole intes- tinal canal, especially the duodenum. Its cathartic effect is succeeded by a mild astringency, which has gained for rhubarb the reputation of being secondarily a calmative, as well as a stimulant of the digestive canal ; with its astringent influence, it likewise exerts, for the most part, a tonic action on the stomach, improving the appetite and digestive powers. It is absorbed in the course of its operation, making the serum of the blood yellow, the sweat tawny, and the urine red, which may be distinguished from bloody urine by heating it. If blood be present it will coagulate, and remove the red color, which will not happen if the tint be owing to rhubarb. Rhubarb is much used as a laxative for infants, in many infantile diseases ; its mildness and tonic qualities ren- dering it peculiarly applicable, especially when enfeebled digestion and irritation of the alimentary canal are present. In acute or chronic diar- rhea or dysentery, in convalescence from exhausting diseases, and in some irritable habits where the mildest of all other laxatives are apt to excite hypercatharsis, rhubarb is an appropriate medicine. Its combi- nation with soap or an alkali tends to counteract its astringent effects, and it thus becomes valuable in cases of constipation. It is useful in all cases of fecal accumulations, as it produces fecal, more than watery discharges. Sometimes it produces griping, which may be obviated by aromatics. The following pill I have found very beneficial in dyspepsia attended with constipation, chronic diarrhea and dysentery, habitual constipation, hepatic derangements, piles, etc.—Take of extract of rhu- barb, leptandrin, hydrastin, and castile soap, of each, half a drachm, mix them well together, and divide into thirty pills ; of these, one, two, three, or four may be taken daily, sufficient to kep the bowels regular, without causing catharsis. When more than one are required daily, they should be given in doses of one pill at a time at regular intervals Rhododendron Chrysanthum. 805 through the day. Rhubarb is generally contra-indicated in cases attended with much inflammatory action. Toasting it, destroys much of its pur- gative power, while its astringency remains the same, and it is, thus prepared, recommended by some practitioners in diarrhea, dysentery, cholera morbus, and other diseases where astringents are indicated. Dose of the powder as a purgative, from ten to thirty grains; as a laxative, from five to ten grains; as a tonic, from one to five grains; of the tincture or syrup, one or two fluidrachms. Off.

Yellow Rhododendron. Nat. Ord.—Ericaceae. Sex. Syst.—Decandria Monogynia. THE LEAVES. Description.—This is a small bush, with the stem from a foot to a foot and a half high, with numerous, decumbent, spreading branches, covered with a brown bark. The leaves are few, alternate, of the texture of a laurel leaf, terminal, ovate, somewhat acute, tapering into the stalk, reticulated and rough above, of a dark-green color, paler, or somewhat ferruginous and smooth underneath, with their margins entire and involute. The flowers are large, showy, nodding, yellow, supported on long peduncles, and varying in number in each cluster from five to ten. The calyx is inferior, persistent, and deeply five-cleft. The corolla is campanulate, five-cleft, with rounded segments, nearly equal, and spreading, the three upper ones somewhat the largest, and streaked with livid dots next the tube, the two lower unspotted. The stamens are ten, with unequal, filiform, declining filaments, and oblong incumbent anthers. The ovary is five-sided, with a long slender style terminated by a five- lobed stigma. The capsule is ovate, somewhat angular, not tomentose, five to ten-celled, containing numerous minute, irregular seeds. History.—Rhododendron is a beautiful evergreen shrub, a native of the mountains of Siberia, with large, yellow flowers, which appear in June and July. The leaves are the parts used in medicine, and should be collected in September, when the capsules are ripe. When dried, they are inodorous, but have an austere, astringent, bitterish taste, and yield their virtues to water or alcohol. The decoction has an unplea- sant odor, and a rough, bitter, and acrid taste. The leaves have not been analyzed. Our native species, the R. Maximum, and R. Punctatum, according to Barton, possess properties similar to the R. Chrysanthum, but milder; according to Bigelow they are astringent, but not narcotic. 806 Materia Medica. Properties and Uses.—Yellow Rhododendron is narcotic, stimulant, and diaphoretic; when first taken, the action of the heart and arteries is increased, followed by a diminished frequency of the pulse ; large doses produce emeto-catharsis, and delirium. They are recommended in infusion, in chronic rheumatism, gout, syphilis, and palsy; two drachms of the dried leaves being infused in ten fluidounces of hot water, for twelve hours, in a close vessel. The liquor is then strained and taken in the morning, one-fourth of it every four hours, and the patient kept in bed ; a repetition of the dose three or four days successively, gener- ally effects a cure. It occasions a sensation of heat, with a species of intoxication, and a peculiar creeping or pricking, and uneasy sensation in the affected parts, which subsides in a few hours, leaving the parts free from pain. It is a valuable remedy, used in Russia, Germany, and sometimes in France and England, but not in this country. RHUS GLABRUM. Sumach. Nat. Ord.—Anacardiaceaa. Sex. Syst.—Pentandria Trigynia. THE BARK AND FRUIT. Description.—As there are several species of this genus which possess poisonous properties, some care should be employed in distinguishing them apart. Rhus Glabrum, or Smooth Sumach, is a shrub from four to fifteen feet in hight, consisting of many straggling, glabrous branches, with a light-gray or somewhat reddish bark. The leaves are upon smooth petioles, and consist of from six to fifteen pairs of opposite leaf- lets, with an odd one at the extremity, all of which are lanceolate, acuminate, acutely serrate, glabrous, green on their upper surface and whitish beneath, sessile except sometimes the terminal odd one, about three inches long, and one-fourth as wide; in the autumn their color changes to a beautiful red. The fiowers are greenish-red, and disposed in large, erect, terminal, compound thyrses, and are succeeded by clus- ters of red berries, covered, when mature, with a crimson down, which is extremely sour to the taste, owing to the presence of malic acid in combination with lime. History. — Rhus Glabrum, sometimes called Upland or Pennsylvania Sumach, is found in almost all parts of the United States, growing in old neglected fields, along fences, and on the borders of woods, flower- ing in June and July, and maturing its fruit in the early part of autumn. The bark and berries are officinal; the latter should be collected before their acid efflorescence is washed away by the rain. They have an acid, astringent, not unpleasant taste. The bark and leaves are astringent, and have been used in dying and tanning leather; when broken from the plant, a milky juice exudes from them, which concretes into a Rhus Glabrum. 807 gummy substance. The excrescences which form upon the leaves, con- tain large quantities of tannic and gallic acids, nearly resembling galls in character, and are fully equal to them in medicinal action. Malic acid may be obtained from the berries by the following process: Pour boiling water on the ripe berries, and let them macerate for twelve hours; then strain, evaporate to one-fourth, and again strain; resume the evaporation and continue it till the liquid assumes the consistence of thin syrup, when it may be set aside to crystallize. Wash the crystals of bimalate of lime which are formed, with a little water, and recrystal- lize from a boiling solution. Dissolve the salt in hot water, and decom- pose it with a solution of acetate of lead. Wash the precipitated malate of lead, suspend it in water, and pass sulphureted hydrogen through the liquid until the whole of the lead is separated. Lastly, filter and evapo- rate to dryness in a porcelain vessel. Malic acid thus prepared may be used for obtaining the malates of iron or of manganese. The Pharmaceutical Institute of New York city profess to have obtained from the leaves of the Rhus Glabrum, the active principle of the plant, which they term Rhusine. It is said to be prepared by per- colation with alcohol of specific gravity 0.830, and then displace the solvent by means of a vacuum apparatus. The Rhusine is then precipi- tated and washed with distilled water, dried on filter-cloth, in an airy, dry room, and reduced to a fine powder. (See Eclectic Journal of Medi- cine, Rochester, Vol. IV, No. VI, page 232.) It is said to be a light brown powder, soluble in hot water, insoluble in alcohol and having a slightly bitter taste. I have not been able to procure any of it, nor a more detailed account of its preparation. Both the bark and berries of Sumach yield their active properties to water. Properties and Uses.—Sumach bark is tonic, astringent and antiseptic ; the berries are refrigerant and diuretic. In decoetion or syrup, the bark of the root has been found valuable in gonorrhea, leucorrhea, diarrhea, dysentery, hectic fever and scrofula. Combined with the barks of Slip- pery Elm and White Pine, in decoction, and taken freely, it is said to have proved highly beneficial in syphilis. Externally, the bark of the root in powder, applied as a poultice to old ulcers, forms an excellent antiseptic; a decoction may also be used in injection for prolapsus uteri and ani, and leucorrhea, and as a wash in many cutaneous diseases; simmered in lard it is valuable in scald-head. A decoction of the inner bark of the root is serviceable in the sore-mouth resulting from mercu- rial salivation, and is much used internally in mercurial diseases. The berries may be used in infusion in diabetes, strangury, bowel-complaints, febrile diseases, etc., as a gargle in quinsy, and ulcerations of the mouth and throat; and as a wash for ringworms, tetters, offensive ulcers, etc. The excrescences which form upon the leaves of the sumach, are nearly equal in astringency to galls, and if pulverized and made into an oint- ment with lard, they afford a soothing application for piles. The gum 808 Materia Medica. which exudes from the bark on being punctured, during the summer, is beneficial in gonorrhea, gleet, obstruction of the urine, and leucorrhea; the following is a good preparation, which increases the secretion of urine, and lessens its burning or scalding: Take of gum sumach, and Canada balsam, of each, equal parts, form into four-grain pills with a sufficient quantity of powdered pokeroot; dose, one or two pills, three times a day. Dose of the decoction of sumach, from one to four fluid- ounces. There are several varieties of this plant, as the R. Typhinum, Stag- horn or Velvet Sumach; and the R. Copallinum, Mountain or Dwarf Sumach, which possess similar virtues, and which must be carefully distinguished from those which possess poisonous properties. The non- poisonous species have their fruit clothed with acid crimson hairs, and their panicles are compound, dense, and terminal; the poisonous vari- eties have axillary panicles, and smooth fruit. Rhusine is said to be tonic, astringent, and antiseptic; and to be of service in diarrhea, dysentery, and bowel diseases generally, in doses of one or two grains, every two, three or four hours, to be given after the exciting cause of these diseases has been removed by other agents.

Description.—There are three species of Rhus, common to this coun- try, which are poisonous, viz: the Rhus Toxicodendron, Rhus Venenata, and Rhus Pumilum. They possess similar medicinal virtues, in a greater or less degree, and should be known to every physician. Rhus Toxicodendron, or Poison Oak, is a creeping shrub from one to three feet high, the root of which sends up many stems, which are either erect, decumbent, or when they meet support, ascend a wall, fence, or tree, in the same manner as ivy, by radicles thrown out at intervals. The bark is of a brownish-gray color. The leaves are ternate, on long semicylindrical petioles; they vary considerably, in the erect varieties being usually entire, or variously and irregularly sinuate-foothed or lobed, while in the climbing kinds they are almost entire or nearly so; in all cases they are smooth on the upper surface, but more or less pubescent beneath. The leaflets are from two to six inches long, and about two-thirds as wide, ovate or rhomboidal, acute, entire, or sinuate- dentate, petiolate ; the lateral leaflets are always inequilateral, nearly sessile, and smaller than the central ones. The flowers are small, greenish-white, dicecious, and grow in lateral, usually axillary, racemose, Rhus Toxicodendron. 809 subsessile panicles. The barren flowers have a calyx of five erect, acute segments, and a corolla of five oblong recurved petals; stamens erect with oblong anthers; in the center is a rudiment of a style. The •fertile flowers are about half the size of the preceding, with calyx and corolla similar, but more erect. They have five small abortive stamens, and a roundish ovary, crowned by a short, erect style bearing three small, cordate stigmas. The fruit is a globular, smooth, dry berry, of a pale-green color approaching to white, and which contains a single bony seed. Rhus Radicans or Poison Ivy, and sometimes Poison Vine, is con- sidered by botanists to be merely a variety of the above species; it has a climbing stem from three to twenty or more feet in length, and ascends trees, rocks, and other objects, to which it adheres by means of myriads of radicating tendrils thrown out from its sides. The leaves are smooth on both sides, sometimes pubescent on the veins underneath. In other respects it resembles the R. Toxicodendron. Rhus Toxicodendron grows in woods, fields, and along fences from Canada to Georgia, flow- ering in June and July. When wounded, it emits a milky juice which becomes black on exposure to the air, and leaves upon linen or cloth, a stain which deepens by age, and which cannot be removed by soap and water, or alcohol. Ether dissolves it. It has been proposed as an indelible ink. The Rhus Venenata, or Poison Sumach, also known as Poison wood, Poison ash, and inappropriately as poison-elder, and poison dog-wood. This has been confounded with the Rhus Vernix of Linnaeus, a species which grows in Japan. It is a shrub or small tree, from ten to fifteen and sometimes thirty feet in hight, with the trunk from one to five inches in diameter, and branching at the top. The bark of the trunk is dark- gray, paler on the branches, and red on the extreme twigs and petioles. The leaves are pinnate, with from three to six pairs of opposite leaflets, and an odd terminal one, which are oblong or oval, entire or slightly sinuated, acuminate, smooth, paler underneath, and nearly sessile, except the odd terminal one ; they are about three inches long, and nearly half as wide. The flowers are dicecious and polygamous, very small, green, and in loose, axillary, pedunculate panicles. The panicles of the barren flowers are downy, the largest and most branched. Sepals five, ovate ; petals five, oblong; stamens longer than the petals, and projecting through their interstices ; the rudiment of a three-cleft style in the center. In the fertile flowers, the panicles are much smaller, sepals and petals resemble the last, while the center is occupied by an oval ovary, terminated by three circular stigmas. The fruit is a bunch of dry berries or drupes, about the size of peas, smooth, greenish-yellow or greenish- white, sometimes marked with slight purple veins, and becoming wrinkled when old ; roundish, a little broadest at the upper end, and compressed, containing one white, hard, furrowed seed. 810 Materia Medica. Rhus Venenata grows in swamps and low grounds, from Canada to Georgia, and flowers in June and July ; it is sometimes termed Swamp Sumach. It furnishes an opake whitish juice when wounded, which becomes permanently black on exposure, and which may, by sufticient boiling, be made to afford a brilliant, glossy, durable varnish, very anal- ogous to that obtained in Japan from the Rhus Vernix. It is much more poisonous than the previous species, and its volatile principle taints the air for some distance around with its pernicious influence, producing in many persons severe swellings of an erysipelatous nature ; sometimes the body becomes enormously swollen, and the patient unable to move. Some persons are hardly or not at all affected even by handling it. The affection caused by it, generally subsides spontaneously after several days, and may be treated in the same manner as named for the poison- ous effects of the R. Toxicodendron. The Rhus Pumilum is considered the most poisonous of the genus. It grows about a foot in hight, and may be distinguished by its pubescent branches and petioles, its pinnate leaves, with many pairs of oval, nearly acuminate, incised-dentate leaflets, downy beneath, and by its silky fruit. It is a southern species, growing in Upper Carolina. History.—Although all parts of the Rhus Toxicodendron are, prob- ably, possessed of active properties, yet the leaves only are officinal. They are inodorous, have a mawkish acrid taste, and yield their virtues to water or alcohol. The best preparation for medical use is a saturated tincture of the recent, leaves, and which should be kept well corked. They have not been satisfactorily analyzed, though known to contain tannic and gallic acids. Properties and Uses.—The fresh juice of the Poison Oak is powerfully irritant. In some persons it produces vesication wherever it is applied, accompanied sometimes by much symptomatic fever,—and even the emanations from the plant are alleged to have the same effect on certain constitutions. To remove these effects, the parts may be bathed with a solution of borax or copperas, or a wash made by boiling the bark of the elder in buttermilk ; accompanied with a light cooling regimen, and cooling purgatives or diuretics. The bruised leaves of the Collinsonia Canadensis, externally, and an infusion of the Verbena, Urticifolia, inter- nally, have been successfully used in internal or external poisoning by these plants. In large doses the leaves and juice are narcotico-irritant, and in small doses, they are diuretic, diaphoretic, laxative, and a stimu- lant of the nervous system. It is said they produce twitchings of para- lyzed muscles, and prickings of the affected limb, similar to strychnia or nux vomica. They have been highly recommended in chronic paralysis, chronic rheumatism, cutaneous diseases, and some diseases of the eye; it is seldom used on account of its poisonous consequences and the volatility of its active principle. I have derived much advantage from Ribes Nigrum. 811 the following preparation in paralysis, chronic rheumatism, and some obstinate cutaneous affections: Take of a saturated tincture of the fresh leaves of Rhus Toxicodendron half a fluidounce, saturated tincture of Aconitum, volatile tincture of Guaiacum, of each, two fluidrachms ; mix together. Of this give forty drops every three or four hours, having previously evacuated the bowels. Rhus Toxicodendron has been em- ployed successfully in paraplegia without any actual organic lesion, likewise in paralysis of the bladder and of the rectum. Dose of the leaves, in powder, half a grain three times a day, gradually increased until some effect is produced; of the saturated tincture from five to ten drops. Off. Prep.—Tinctura Rhus Toxicodendri. RIBES NIGRUM. Black Currant. Nat. Ord.—Grossulaceae. Sex. Syst.—Pentandria Monogynia. THE FRUIT. Description.—The Black Currant is a woody bush or shrub from three to five feet in hight, stems unarmed, and the leaves from three to five lobed, punctate beneath, dentate-serrate, longer than their petioles. Racemes lax, hairy, somewhat nodding. Calyx campanulate, with reflexed segments; petals oblong, yellowish ; bracts minute, subulate or blunt, nearly as long as the pedicels. Fruit large, roundish-ovoid, nearly black. Ribes Rubrum, or common Red Currant, has unarmed, straggling or reclined stems, with leaves obtusely three to five-lobed, smooth above, pubescent beneath, subcordate at base, margin mucronately serrate. The racemes are from lateral buds distinct from the leaves, pendulous, and nearly glabrous. Bracts blunt, shorter than the pedicels. Calyx flattened out, short, spreading, with obtuse lobes; petals obcordate, green. Fruit globose, smooth, red. History.—The Black Currant is a native of Europe and Siberia, grow- ing in woods, cultivated in Europe and this country, and flowering in May. The Red Currant grows in cold damp woods and bogs in this country and Europe, and is extensively cultivated in gardens ; it also flowers in May. The fruit of these two plants, is the part used, and imparts its virtues to water. The juice of Red Currants is said to con- tain citric acid, malic acid, sugar, vegetable jelly, gum, and extractive; that of Black Currants contains the same, with the addition of a pecu- liar volatile principle, and a violet coloring matter. Properties and Uses.—The juice of these berries, especially of the black currant, is said to be diuretic and diaphoretic. They may be made into a jelly, a jam, paste, etc., and are very useful in febrile and 812 Materia Medica. inflammatory cases, in hoarseness and affections of the throat. The raw juice is an excellent refrigerant beverage in febrile diseases. A decoc- tion of the bark of the black currant has proved useful in calculous affections, dropsy, and hemorrhoidal tumors. The wild black currant, Ribes Floridum, of this country, possesses similar properties. It is a handsome shrub, growing from three to five feet high, with leaves one or two inches long, and somewhat wider, subcordate, from three to five lobed, lobes acute, spreading, sprinkled on both sides with yellowish, resinous dots, just visible to the naked eye. Flowers greenish-yellow, subcampanulate, in pendulous, pubescent, many flowered racemes. Calyx cylindrical; bracts linear, longer than the pedicels; petioles one or two inches long. Fruit obovoid, smooth, black, insipid. It flowers in May and June. ROBINIA PSEUDO-ACACIA. Locust Tree. Nat. Ord.—Fabaceae, or Leguminosae. Sex. Syst.—Diadelphia Decandria. the bark and leaves. Description.—This is a tree from forty to fifty, and in favorable situa- tions, eighty feet in hight, with a diameter of from one to four feet, and covered with a darkish-colored rough bark. The branches are numerous, and armed with short, strong spines. The leaves are unequally pinnate; the leaflets are from four to eight or twelve pairs, with an odd one at the end, ovate, and oblong-ovate, thin, nearly sessile and very smooth, with minute, setaceous, partial stipules, and of a bright green color. The flowers are produced from the sides of the branches, in long pendulous racemes, are numerous, white, fragrant, and are succeeded by com- pressed pods or legumes, about three or four inches in length, and half an inch in width, and containing five or six brown, hard, reniform seeds. When young, the tree is armed with thorns which disappear in its maturity. History.—This tree, known also by the names of Black Locust, and Yellow Locust, is found in many parts of the United States, principally west of the mountains, being seldom found north of Pennsylvania, or in the Atlantic Southern States ; it blossoms in May. It is highly esteemed for the durability, hardness and lightness of its wood. The bark and leaves are used, and yield their properties to water or alcohol. The bark of the root is the most active. The seeds are sub-acrid, and fur- nish a large quantity of oil on expression ; by infusion in water, they become perfectly mild, and afford an excellent farina. The inner bark is fibrous, and capable of being spun. No analysis has been made of this tree. Roccella Tinctoria. 813 Properties and Uses.—The bark of the root is sweetish, but emetic and cathartic ; in small doses, tonic. An ounce of the bark boiled in three gills of water operates as a cathartic in doses of half an ounce, given morning and evening. The bark is supposed to possess some acro- narcotic properties, as the juice of it has been known to produce coma and slight convulsions. The flowers possess antispasmodic properties, and form an excellent and agreeable syrup. The leaves operate mildly and efficiently as an emetic, in doses of thirty grains every twenty minutes. ROCCELLA TINCTORIA. Litmus. Nat. Ord-—Lichenales. Sex. Syst.—Cryptogamia Lichens. A PECULIAR COLORING MATTER. Description.—Roccella Tinctoria, or Orchilla-weed, is a small dry lichen, with a rounded, glaucous, nearly erect thallus, forked and subdivided into numerous, branchy, roundish, gray, yellowdsh or brownish threads; apothecia scattered and elevated ; disk flat, caesius, pruinose, as broad as the border. History.—This lichen abounds on alpine or maritime rocks in various parts of the world, and chiefly upon the European and African coasts, and the neighboring Madeira, Canary, Cape de Verds, etc. islands. It contains a resinoid matter, a waxy principle, mucilaginous extractive, lichenin, oxalate of lime and various other salts, and Roccellic and Erythric acids. Litmus was formerly obtained from this plant alone, but other lichens have now in a great measure supplanted it, as the Roccella Fusiformis or Angola-weed, from Angola and Madagascar, the Lecanora Tartarea or Tartarean Moss, from Norway and Sweden, the Variolaria Dealbata from Auvergne and the Pyrennees, and some others. The principles in these plants upon which their properties depend, are themselves colorless, and yield coloring substances by the reaction of water, air, and ammonia ; they are generally acids. Lacmus or Litmus is prepared chiefly in Holland. It is made by coarsely powdering the lichen, and then placing it in close wooden ves- sels, containing urine, lime, and potassa or soda mixed together, allowing it to macerate for several weeks, with occasional agitation. Fermenta- tion takes place, the mass becomes red and then blue, is mixed with cal- careous or siliceous matter to give it consistence, and with indigo to deepen the color, and placed into small molds to harden. It is in rect- angular cakes from a quarter of an inch to an inch in length, light, friable, finely granular, of an indigo blue or deep violet color, and scattered over with white saline points. It has the combined odor of indigo and violets, tinges the saliva a deep blue, and is somewhat pungent 814 Materia Medica. and saline to the taste. It is reddened by acids, and restored to its original blue color by alkalies. Properties and Uses.—Litmus is much used in investigations of the urine, and other analyses, as one of the most delicate tests of uncom- bined acids, which change its blue color to red ; and of alkalies which restore the reddened litmus to its original hue. It is used either in infu- sion, or in the form of litmus paper. The infusion, called Tincture of Litmus, is prepared by adding one part of litmus to twenty of distilled water, boiling it, and then adding two parts of alcohol to preserve it. Litmus paper is prepared by first boiling for half an hour, one part of litmus with four of water, and thus forming a strong and clear decoction ; then by means of a brush, apply it to only one surface of white, unsized paper, carefully dry it, and then keep it in well-closed vessels, and not exposed to the action of the light. Orchil or Archil, is the lichen, turned to a violet or deep reddish- purple color. It is in the form of a thickish liquid, or consists of a con- fused mass of violet-colored threads. It is prepared by macerating lichens, in a covered wooden vessel, with an ammoniacal liquor, either consisting of stale urine and lime, or prepared by distilling an impure salt of ammonia with lime and water. Cudbear is prepared in the same manner as Orchil; but after the development of the color, it is dried and pulverized, forming a purplish-red powder. The difference in the preparation of these dye-stuffs and litmus, is that in the latter, potassa or soda, is added to the ammoniacal liquid used. ROSA CANINA. Dog-Rose. Nat. Ord.—Rosaceae. Sex. Syst.—Icosandria Polygynia. THE RECENT FRUIT. Description.—This plant, also known by the names of Hip-tree, or Wild-brier, is a soft, branched, smooth bush, with long green curved roots hoots, which are covered with equal, remote, strong, compressed, falcate prickles; the leaflets are from five to nine, ovate, firm, Avithout glandular pubescence, with acute, incurved and often double serratures. The flowers with leafy bracts. Sepals partly pinnated, usually naked as well as the tube of the calyx. Petals white or pink, obcordate, fragrant; throat of the calyx thick and quite closed up. Fruit red, succulent, ovoid, truncated in consequence of the fall of the sepals. History.—This plant is a native of Europe, and introduced into this country ; it usually attains the hight of eight or ten feet, and flowers in June and July. The flowers are succeeded by a scarlet fruit called Hip. The fruit, (Rosce Fnidus,) is the only officinal part, it is inodorous, but possesses a rather pleasant, sweetish, acidulous taste, which is increased Rosa Centifolia. 815 by the action of frost. The hip or fruit consists of the developed tube of the calyx, inclosing within its cavity numerous carpels or true fruits ; these must be carefully removed before it is used for pharmaceutic pur- poses. It then, after having been dried, consists of gum, citric acid, impure malic acid, a large proportion of uncrystallizable sugar, various salts, and traces of wax, resin, and volatile oil. Its properties are pre- served by beating the pulp with sugar. Properties and Uses.—The conserve made by beating the pulp with sugar, is called Conserve of Dog-Rose, or Conserve of Hips, ( Confectio Rosen Caninm,) and is tenacious, retaining its softness for a long time, even under exposure to the air. It is a useful material for forming pill- masses, and, as it contains less tannic acid, may be used as a substitute for the conserve of red roses, when preparations of iron are to enter into the pill mass. _______ ROSA CENTIFOLIA. Hundred-leaved Rose. Nat. Ord.—Rosaceae. Sex. Syst.—Icosandria Polygynia. THE PETALS. Description.—This is an erect shrub, from three to six feet in hight, and having the branches closely covered with nearly straight prickles, scarcely dilated at base, and glandular bristles of various forms and sizes ; the large ones falcate. Shoots erect. The leaves consist of two or three pairs of leaflets, with an odd one at the end, closely attached to the common footstalk, which is rough, but without spines. The leaflets are ovate, broad, pointed, glandular-ciliate on the margin, sub-pilose beneath. The flowers are large, several together, drooping, on peduncles beset with short hairs, and fringed with glands. Sepals leafy, com- pound, viscid. Petals usually of a pale-red color. Fruit ovoid, and the segments of the calyx semi-pinnate. History. — The native country of this rose-bush is unknown; but it is extensively cultivated in nearly all parts of the world, forming a valu- able ornament to gardens. Its varieties are numerous, differing in form, size, color, etc. The most fragrant varieties are the best adapted for use. The parts used are the petals of the fully expanded flowers, Avell dried, or preserved by means of salt. They have a delicious fragrance, and a sweetish, slightly acidulous and bitter taste, with a faint astrin- gency. Iodine is said to increase the fragrance, which depends on a volatile oil which may be separated with water. (See Oleum Rosai.) Properties and Uses.—The petals, or a syrup of them is slightly lax- ative ; their principal use, however, is in the preparation of Rose-Avater, so much used in collyria and other lotions, and on account of its agreeable odor.

Description.—The Red, French, or Provins Rose, is a dwarfish, stiff, short-branched bush, from tAvo to three feet high, with the stem and petioles armed with numerous fine, nearly equal, uniform prickles and glandular bristles intermixed. The leaflets, mostly five, are stiff, ellipti- cal, and rugose. The flowers are large, erect, several together, with leafy bracts. The sepals are ovate, leafy, compound. The petals are five or more, obcordate, large, spreading, and of a rich crimson color. The fruit is oval, shining, and of a firm consistence. History.—The Red Rose is a native of the south of Europe, but is cultivated in our gardens, flowering in June and July. There are many varieties, some of which are very unlike the original. With this plant, as with the previous ones, cultivation multiplies the petals very much, by the conversion of stamina. The petals are the parts used. They should be gathered before the flower has blown, deprived of their whitish claws, dried in the sun, or by a warm fire, and kept in a dry place. They retain their color when dried, and their odor becomes much improved. They have a velvety appearance, a purplish-red color, and an aromatic, bitterish, astringent, feebly acid taste ; and which is com- municated to water. The pale-red infusion becomes bright-red on the addition of sulphuric acid ; and yields a black precipitate with the salts of sesquioxide of iron. Exposure to light and air impairs their proper- ties, they should therefore be kept in well-closed opake vessels. The addition of honey or sugar, preserves their properties, whether in the petals, or in infusion. They contain tannic acid, gallic acid, color- ing matter, a volatile oil, a fixed oil, alhumen, soluble salts of potassa, insoluble salts of lime, silica, and oxide of iron. Properties and Uses.—Red Roses are slightly astringent and tonic. They have been used in passive hemorrhages, and excessive mucous discharges. They have also been found beneficial in bowel complaints, and are more commonly used in ophthalmic diseases, as a poultice, or the pith of sassafras and infusion of roses as a collyrium in acute oph- thalmia. The infusion is also used as a vehicle for tonic and astringent medicines. The infusion, with the addition of sulphuric acid, is an agreeable refrigerant and astringent in some cases. The confection is a very common pill basis, and it is for this purpose that the article is principally employed. If iron be added to the confection, or any of its preparations, it forms a hard pill, which passes through the alimentary canal unchanged. Off. Prep.—Confectio Rosae.

Description.—Rosemary is an erect, perennial, evergreen shrub, three or four feet high, divided into many long, slender, ash-colored branches, and densely leafy. The leaves are sessile, opposite, linear, over an inch in length, and about two lines broad, entire, obtuse at the summit, revo- lute at the margins, of a firm consistence, smooth and green on the upper surface, whitish and downy beneath. The flowers are few, pale blue or white, subsessile, and disposed in short, opposite, axillary and terminal racemes. The brads are shorter than the calyx. The calyx is purplish, campanulate and villous; the corolla is ringent, longer than the calyx, with the upper lip erect and bifid; the lower divided into three segments, the middle one of which is largest, concave, and emar- ginate. The leaves and flowers exhale a fragrant camphoraceous odor. The stamens are two, longer than the corolla, curved and furnished with a minute tooth near the base; the anthers are oblong and of a blue color. The style is as long as the stamens, curved and furnished with pointed stigmas. The seeds are four, naked and situated at the base of the calyx. History. — Rosemary is a native of the countries surrounding the Mediterranean, and is cultivated in the gardens of Europe and this country. The flowers and leaves of the wild variety are said to be larger than those of the cultivated. The officinal parts are the flower- ing tops, which haAre a powerful, diffusive, camphoraceous odor, and an aromatic, bitter taste; they yield their properties to water or spirit, but more completely to alcohol. Age and drying impair their odor and properties, which are owing to a volatile oil, and which may be obtained by distillation. On standing for some time, the oil deposits crystals of camphor. Properties and Uses. — Rosemary is stimulant, antispasmodic, and emmenagogue; seldom used in this country, except as a perfume for ointments, liniments, embrocations, etc. The oil is principally employed. Dose, internally, from three to six drops. Off. Prep.—Oleum Rosmarini. RUBIA TINCTORUM. Madder. Nat. Ord.—Rubiacea?. Sex. Syst.—Tetrandria Monogynia. THE ROOT. Description.—Dyers' Madder has a perennial root, composed of numer- ous long succulent fibers, of various sizes, and united to a common head. 52 818 Materia Medica. The stems are many, slender, quadrangular, jointed, decumbent, diffuse, brittle, branched and furnished at the angles with short prickles, by means of which they can climb on a support. The leaves are from four to six in a Avhorl, elliptical, acuminate, rough on edges and midrib, somewhat membranous, with pinnated veins, about three inches long, and nearly one inch broad. The flowers are small, yellow, and termi- nal, forming a ramose panicle. The corolla is rotate, four-cleft, with the lobes ovate-lanceolate, apiculate, and somewhat callous. The sta- mens are short; anthers ovate-oblong; styles short; and stigmas conical. The fruit is a round, shining black berry, or rather double berry, one of which is abortive. History.—Madder is a native of the South of Europe, and is exten- sively cultivated in France and Holland; from which last place is derived the principal supply. The root is the part used; it is dug up in the third summer, deprived of its cuticle, dried by artificial heat, and then reduced to a coarse powder, which is of a brownish-red color. The root consists of a thin epidermis, covering an easily separable cortex, and a ligneous meditullium, which is at first yellow, but on drying becomes reddish. The plant is cultivated in the State of Ohio. Madder has a weak peculiar odor, a bitterish, astringent taste, and imparts its color and properties to water or alcohol. According to analysis, madder contains sugar, resiri, and five coloring matters, and according to Runge, Madderic and Rubiacic acids. The coloring substances are a red, a purple, an orange, a yellow, and a brown. One of these, Xanthin, has been noticed by Kuhlmann, and two others Purpurin and Alizarin, by Robiquet and Colin. The coloring matters are probably all modifica- tions of a single substance, which appears to be the Xanthin, as at first the juice of the root is yellow, and does not become red only under exposure to the atmospheric oxygen. The alizarin is the most interest- ing of the coloring substances. It is of an orange-red color, inodorous, tasteless, crystallizable, sublimes without change, hardly soluble in cold water, but soluble in boiling, readily soluble in alcohol, ether, fixed oils, and alkaline solutions. The alcoholic and watery solutions are rose- colored; the ethereal, golden yellow ; the alkaline, violet and blue when concentrated, but violet-red when sufficiently diluted. A precipitation of a mixture of the solutions of alum and alizarin, affords a beautiful rose-colored lake. When taken into the stomach, the coloring matter of madder is absorbed, and the urine, milk, and bones become colored red, though none of the other tissues are affected by it. Properties and Uses.—Madder is supposed to be emmenagogue and diuretic, and has been recommended for such purposes by various prac- titioners. However, it is not in general use, as the profession lack confidence in its action. The dose is thirty grains, three or four times a day.

Syst.—Icosandria Polygynia. THE BARK OF THE ROOT, AND RASPBERRY LEAVES. Description.—Rubus Strigosus is a shrubby, strongly hispid plant, about four feet in hight. The leaves are pinnately three or five-foliate, with the leaflets oblong-ovate or oval, obtuse at base, pointed, coarsely and unequally serrate, green above, canescent tomentose beneath, lateral ones sessile, odd one often subcordate at base, and distinctly petiolulate ; they are from one and a half to two and a half inches long, and about from one-third to two-thirds as wide. The flowers are white, and in panicled corymbs. The corolla is cup-shaped, and about the length of the calyx. The fruit is a red berry, hemispherical, com- posed of many juicy, one-seeded acini, on a dry receptacle, of a rich delicious flavor. Rubus Trivialis or Rubus Canadensis, sometimes called Low or Creep- ing Blackberry, has a slender, prickly stem, which runs along the ground for several yards. The leaves are petiolate and composed of three, (or pedately five or seven) leaflets, which are elliptical, or rhomboidal-oval, acute, thin, membranaceous, sharply and unequally cut-serrate, often somewhat incised, somewhat pubescent, from an inch to an inch and a half long, and about one-half as wide. The common petioles are one or two inches long, and together with the peduncles, are armed with recurved, hispid prickles ; sometimes naked. The stipules are linear, subulate, entire, or serrate. The flowers are large, white, nearly soli- tary, on slender, elongated, prickly, somewhat corymbed pedicels, with leafy bracts ; the lower peduncles distant, the upper crowded. The petals are obovate, in one variety orbicular, and twice as long as the calyx. Fruit large, black, very sweet and juicy. Rubus Villosus, is a pubescent, viscid and prickly shrub, with a horizontal, perennial, irregularly tuberous, woody root, of a reddish- brown color, from which arise tall, slender, angular, and biennial stems from three to seven feet high, of a brownish color, branching, recurved at top, more or less furrowed, and armed with strong, curved prickles. The smaller branches and new shoots are decumbent, herbaceous, greenish, pubescent and prickly. The leaves are ternate or quinate, and are composed of from three to five leaflets, which are ovate, acuminate, 620 Materia Medica. sharply and unequally serrate, and pubescent on both sides; the petioles and midrib usually armed with short recurved prickles. The flowers are large, white, and in erect terminal panicles or racemes ; the calyx is short, with acuminate segments ; the petals are five, obovate or oblong, obtuse; stamens numerous; fllaments slender; anthers small. The fruit is large, at first green, then red, and when matured, black, it consists of about twenty roundish, shining, black, fleshy carpels, closely collected into an ovate or oblong head, subacid, well-flavored, and ripening in August and September. History.—The Red-raspberry grows wild, and is common to Canada and the Northern United States, growing in hedges, neglected fields, thickets and hills, flowering in May, and ripening its fruit from June to August. The leaves are the officinal parts. They impart their proper- ties to water, giving to the infusion an odor and flavor somewhat similar to that of some kinds of black tea. The Dewberry likewise grows wild in dry, stony fields, gravelly soil, and neglected grounds, and is common from Canada to Virginia, flow- ering in May, and ripening its fruit in July and August. The root is the officinal part, it is generally smaller than the blackberry root, with transverse fissures through the epidermis, but no longitudinal wrinkles, of a dark-ash color, without any reddish tinge, inodorous, with a bitter- ish, strongly astringent taste. Blackberry grows abundantly in most parts of the United States, in neglected fields, along fences, on the borders of woods, etc. Its flowers appear from May to July, and its fruit is matured in August. The root is the officinal portion, it is branch- ing, cylindrical, of various dimensions, from an inch down to two or three lines in diameter, ligneous, covered with a thin light brown or reddish brown bark, Avhich when dried is wrinkled longitudinally. These plants possess similar medicinal properties, and may be substi- tuted the one for the other; and as they belong to the same genus, I have placed them together. The bark of the old roots, or the smaller roots, of dewberry and blackberry, should always be selected for use, as the woody portion is inert; their odor and taste are similar, and they impart their virtues to boiling water, or diluted alcohol. They contain a large quantity of tannic acid, with bitter extractive ; no accurate analysis has been made of them. The fruits of these plants are much esteemed as an article of diet, and have been manufactured into cordial, jam, jelly, and syrup. They contain volatile oil, citric and malic acids, sugar, mucus, etc. Properties and Uses.—These plants are tonic and strongly astringent. Ah infusion or decoction of the leaves of raspberry, or of the bark of the roots of the other two, has been found an excellent remedy in diarrhea, dysentery, cholera-infantum, relaxed conditions of the intestines of children, passive hemorrhage from the stomach, bowels, or uterus, and Rudbeckia Laciniata. 821 in colliquative diarrhea. The decoction used as an injection, is useful in gonorrhea, gleet, leucorrhea, and prolapsus uteri and ani; in prolapsus uteri, it may be used either alone or combined with the internal use of a decoction of equal parts of black cohosh and blackberry roots, taken freely. The leaves of raspberry, in decoction with cream, will allay nausea and vomiting, and combined with aromatics has been found useful in diarrhea, cholera-morbus and cholera-infantum. It is said that the raspberry exerts an influence over the uterus during parturition, exciting its contractions when other agents have failed, and has been found ser- viceable in after-pains. The fruit, especially that of the blackberry, makes an excellent syrup, which is of much service in dysentery, being grateful to the patient, relieving the tenesmus which so constantly attends the disease, and ultimately effecting a cure. The fruit of the raspberry contains very little nourishment, but is an agreeable acidulous article, rarely disturbing the stomach, and when eaten freely, promotes the action of the bowels. Raspberry syrup added to water, forms a refreshing and beneficial beverage for fever-patients, and during con- valescence. The jelly or jam may likewise be used in similar cases ; that of the blackberries being more astringent, is better adapted to cases of diarrhea, dysentery, and cholera-infantum. Dose of the decoction of these plants, from one to four fluidounces several times a day; of the pulverized root-bark from twenty to thirty grains. The Rubus Odoratus, or Rose-flowering Raspberry, has an erect or reclining, unarmed, glandular-pilose, shrubby stem, from three to five feet in hight. The leaves are from four to eight inches long, nearly as wide, cordate at base, palmately three to five-lobed, unequally serrate, lobes acuminate, the middle one prolonged, petioles two or three inches long, and with the peduncles, calyx and branches, clothed with viscid hairs. Flowers many, large, nearly two inches in diameter, in terminal corymbs. Petals orbicular, purple-rose color; stamens numerous, whit- ish. Fruit broad and thin, bright-red, sweet. This plant grows on rocky banks, and in upland woods in the United States and Canada, flowering in June and July, and ripening its fruit in August. A decoc- tion of it is said to be powerfully diuretic, and may be used freely in affections of the urinary organs, and dropsy. RUDBECKIA LACINIATA. Thimbleweed. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Frustranea. THE WHOLE PLANT. Description.—This plant, also known by the names of Cone-disk Sun- flower, and Tall Cone-flower, is a tall, showy, indigenous, perennial plant, with a round, glabrous, branching stem, from three to eight feet in hight. 822 Materia Medica. The leaves are alternate, smooth or roughish, the lower ones pinnate with from five to seven cut or three-lobed leaflets, petiolate, the upper ones irregularly three to five-parted ; the lobes ovate-lanceolate, pointed. The flowers are large, and terminal; pappus crenate ; chaff truncate and downy at the tip. Rays one or two inches long, oblanceolate, bright yellow, spreading or drooping. Disk oblong-conical, and columnar in fruit, greenish-yellow. History.—This plant grows in various parts of the United States, in damp places, low thickets, edges of swamps and ditches, etc., flowering from July to September. The whole herb is recommended to be used. Its chemical reactions, as well as formation, are not known. It imparts its properties to water. Properties and Uses. — Thimbleweed is a valuable diuretic, tonic and balsamic. Useful in many diseases of the urinary organs, and highly recommended in strangury, Bright's disease, and wasting or atrophy of the kidneys. Dose of the decoction, ad libitum. The Rudbeckia Purpurea of Linnaeus, variously called Red Sun- flower, Comb-flower, or Purple Cone-flower (the Echinacea Purpurea of Mcenchausen), has a thick, black root, with branched, sulcate, smooth or rough stems, growing from three to five feet in hight. The leaves are alternate, from four to eight inches long, and about one-fifth as wide, rough, with short stiff bristles; the lower ones broad-ovate, attenuate at base, five-nerved, veiny, long-petioled, remotely-toothed; the cauline ones lanceolate-ovate, acuminate, nearly entire. Heads large, solitary, on long peduncles. Disk thickly beset with the stiff, pointed, brown chaff. Rays from fifteen to twenty, two or three inches long, dull purple, pendulous, bifid. This plant is common to the Western prairies and banks, and is found also in the Southern States flowering from July to September. The root is very pungent to the taste, and has been popu- larly used in medicine under the name of Black Sampson; it is stated to have been employed with much benefit in syphilis. Both of the above plants, deserve a full and thorough investigation from the profession. From all I have been able to learn, the latter plant is equal to the Stil- lingia in medicinal efficacy. RUMEX ACETOSA. Sorrel. Nat. Ord.—Polygonaceae. Sex. Syst.—Hexandria Trigynia. the leaves. Description.—Rumex Acetosa has a long and tapering, somewhat woody root, with an erect, simple, leafy, striated stem, one or two feet high. The lower leaves are petiolate, somewhat ovate, arrow-shaped, with two lateral teeth ; the upper ones are sessile, more oblong and narrower. Stipule tubular, membranous, fringed. Clusters erect, Rumex Aquaticus, Britannica, etc. 823 compound, whorled, leafless. Flowers dicecious. Males green with a reddish tinge; inner sepals ovate, rather larger than the outer. Females rather redder; inner sepals ovate, obtuse, red, entire, each bearing an oblong pale tubercle. The whole herb is smooth and powerfully and agreeably acid. The root is astringent. The plant is common to Eng- land, and is sometimes cultivated in this country. Rumex Acetosella, Field or Sheep Sorrel, has a leafy stem from six to twelve inches in hight, with lanceolate-hastate, pleasantly acid leaves. The flowers small, reddish, collected in panicled racemes, the valves are ovate scarcely enlarging in fruit, destitute of granules. The stamens and styles on separate plants; the styles adherent to the angles of the ovary. This weed is found in abundance throughout the United States, growing in pastures, waste grounds, and worn fields, and flowering all summer. History.—The leaves of these two plants are the parts used in medi- cine ; they are inodorous, and have an agreeable sourness, which latter depends on the presence of binoxalate of potassa, with a small propor- tion of tartaric acid; by drying them this taste is lost. They are used alone, or in an infusion of the fresh leaves. Properties and Uses.—Fresh Sorrel leaves are refrigerant and diuretic; an infusion is useful in febrile and inflammatory diseases, and in scorbutic complaints. They may likewise be prepared in the form of salad, or boiled like spinage. The leaves eaten largely are said to have produced poisonous effects, owing to the oxalic acid they contain. Wrapped up and roasted, the leaves form an excellent application to indolent tumors, wens, boils, etc., hastening suppuration. The inspissated juice, applied on leather, is said to form an effectual but painful cure for tumors and incipient cancers. Acting upon this hint, the following preparation has been found a useful remedy in cutaneous cancer, viz: Take of Burnt Alum, one drachm; Citric or Tartaric Acid, two drachms; Oxalic Acid, two drachms; Rain Water, half a pint. Mix. To be applied by means of a camel's hair pencil. RUMEX AQUATICUS. Great Water Dock. RUMEX BRITANNICA. Water Dock. RUMEX OBTUSIFOLIUS. Blunt Leaved Dock. RUMEX CRISPUS. Yellow Dock. Nat. Ord.—Polygonaceae. Sex. Syst.—Hexandria Trigynia. THE ROOT. Description.—Rumex Aquaticus has a large thick root, externally black, internally whitish, with an erect stem from three to five feet high; 824 Materia Medica. the leaves are a foot or more in length, and three to five inches wide, smooth, lanceolate, pointed, the lower ones cordate, on long petioles. The flowers are verticillate, and are disposed in a terminal leafy panicle. Pedicels capillary, drooping. The three petals, or as termed by some botanists, the three inner divisions of the calyx, approach each other, so as to assume a triangular shape, and in this state are called valves; these are large, ovate, obtuse, entire, and are each furnished with a small, linear, often obscure grain, extending down the middle. The plant is a native of Europe, but naturalized in America. It grows in this country in ponds and ditches, and flowers in July and August. Rumex Britannica, or Yellow-rooted Water Dock, has a large root, externally dark, internally yellowish, with an angular, furrowed, branch- ing stem, two or three feet high. The leaves are broad-lanceolate, acute at both ends, from three to five inches long, petiolate, flat, smooth, with the sheathing stipules slightly torn. The flowers are perfect, in verticil- late fascicles, collected into a large, terminal panicle, the spikes of which are nearly leafless. The pedicels are capillary and nodding in fruit. The calyx valves large, cordate, entire, graniferous, two of the grains small or abortive. This plant is indigenous, growing in low, Avet places, in various parts of the United States, and flowering in June and July. Rumex Obtusifolius, or Blunt Leaved Dock, has its root brown exter- nally, and yellow internally; the stem is two or three feet high, furrowed, somewhat roughish, branching, and leafy. The radical leaves are about a foot long, and five or six inches in width, ovate-cordate, obtuse, rather downy on the veins underneath, somewhat wavy margined, often with stalk and veins red; the upper ones are oblong-lanceolate, and acute. The flowers are in long, nearly naked racemes ; whorls loose and distant; valves ovate-halbert shaped, sharply denticulate at the base, strongly reticulated, one of them principally bearing a granule on the back. This is a common weed, growing in rich grounds and pastures, and about houses, flowering in June and July. It is supposed to have been introduced from Europe. Rumex Crispus, or Yellow Dock, is the species of Dock more com- monly used by Eclectics, and is, perhaps, the only one entitled to an officinal rank in our Dispensatory. It has a deep spindle-shaped, yellow root, with a stem two or three feet high, angular, furrowed, somewhat zigzag, smooth to the touch, panicled, leafy. The leaves are lanceolate, acute, strongly undulated, and crisped at the edges, of a light-green color ; the radical ones on long petioles, truncate, or subcordate at base; the uppermost narrower, and nearly sessile. The flowers are numerous, pale-green, drooping, disposed in a large panicle consisting of many wand-like racemes of half-whorls, interspersed with leaves below. Inner sepals, or valves, much larger than the outer, veiny, waved, entire, ovate, each bearing a large ovate brown grain or tubercle on the back. Ruta Graveolens. 825 Nut contracted at each end, with three blunt or tumid angles. This plant is a native of Europe, introduced into this country, where it grows Avild in pastures, dry fields, waste grounds, etc., flowering in June and July. History. —I have placed these four species of dock together, in con- sequence of their possessing similar medicinal properties, and Avhich under separate heads would lead to an unnecessary repetition. The roots of several other species have been medicinally employed, and may be used indiscriminately with the above, as the R. Patientia and R. Alpinus of Europe, and the R. Acutus and R. Sanguineus of this coun- try. These various dock-roots have little or no odor, a bitter astringent taste, and readily yield their virtues to water by decoction. They have not all been analyzed. The R. Obtus'folius contains a peculiar princi- ple called Rumicin, resin, extractive matter resembling tannic acid, starch, albumen, mucilage, lignin, sulphur, and various salts. The young leaves of some of the species are occasionally used as spinage. As found in the shops, yellow dock-root is in slices cut transversely and dried, and occasionally the root is divided longitudinally into halves or quarters; it is sometimes called Sour Dock, Narrow Dock, or Curled Dock. Properties and Uses.—The dock-roots are alterative, tonic, mildly astringent, and detergent, and are eminently useful in scorbutic, cuta- neous, scrofulous, scirrhous, and syphilitic affections, leprosy, elephan- tiasis, etc.; for which purpose we prefer the Rumex Crispus. The fresh root bruised in cream, lard, or fresh butter, forms an excellent ointment for scrofulous ulcers, scrofulous ophthalmia, itch, and a discutient for indolent glandular tumors. An ointment of the root of R. Crispus, and the root-bark of Celastrus Scandens, with gunpowder, is said to form a certain cure for the itch, as well as being of value in other cutaneous diseases, and ulcers. The powdered root is recommended as a dentifrice, especially when the gums are spongy. Dose of the decoction or syrup, from one to four fluidounces, three times a day. Off.

Description.—Rue is a perennial plant, with shrubby branching stems, two or three feet in hight, woody at the lower part and covered with a rough, gray bark, but smooth, green, and herbaceous in the upper part and branches. The leaves are alternate, smooth, glaucous, a little tomentose, transparently dotted, and doubly pinnate; the leaflets are 826 Materia Medica. sessile, unequal, obscurely crenate, somewhat thick and fleshy; the lateral lobes linear or nearly so ; and the terminal ones larger and obo- vate. The flowers are of a pale greenish-yellow color, and disposed in terminal corymbose panicles, upon subdividing peduncles ; the terminal, or first unfolded, only having the full number of the parts of fructifica- tion ; the others having eight stamens and four sepals and petals. The petals are large, rounded a little, toothed at the extremity, and concave, attached by narrow claAvs. The stamens are equal, with small yellow anthers. The ovary is oval, with crucial furrows, and is surmounted by a short style. The capsule is gibbous, four-lobed, and bursts at the summit of each lobe, for the passage of numerous, angular, blackish seeds. The process of impregnation is singular, each anther in turn approaching the style, and after shedding its pollen, retiring. History. — Rue is a well known, hardy, evergreen undershrub, a native of the south of Europe and north of Africa, and cultivated in our gardens, flowering from June to September. The whole plant has a strong, peculiar, disagreeable odor. The whole herbaceous portion of it possesses medicinal activity, but the leaves are more generally em- ployed. They have a strong, disagreeable odor, and a disagreeable, bitter, acrid taste. In the recent state they will inflame and vesicate the skin. They should be gathered when the seed vessels are well- developed, yet still green; the seed-vessels of the unripe fruit are covered with large oil vesicles, and may likewise be used for medical purposes. The virtues of this plant are owing to a volatile oil, which is abundantly contained in glandular vesicles, with which it is covered, and which may be obtained by distillation with water. It yields its properties to boiling water in infusion, but alcohol is its best solvent. The plant loses much of its activity by drying. Beside volatile oil, the plant is said to contain albumen, chlorophylle, extractive, gum, starch or inulin, an azotized matter, malic acid, lignin, and a peculiar acid called Rutinic acid. Properties and Uses. — Rue is emmenagogue, ecbolic, anthelmintic and antispasmodic. In large doses it acts as a narcotico-acrid poison. It has been taken by pregnant women, and produced dangerous symp- toms of gastro-intestinal inflammation, and cerebral derangement, termi- nating in miscarriage. Its action is chiefly directed upon the uterus, and is capable of exciting menorrhagia, inflammation, and miscarriage. It has been successfully used in flatulent colic, hysteria, some nervous complaints, epilepsy, and as an excellent vermifuge. Dose of the leaves, from ten to twenty grains ; of the decoction, from one to four fluidounces ; of the oil, from two to six drops. Off. Prep.—Infusum Rutee; Oleum Rutee.

Description.—This plant, also called Rose-pink, has a yellow, fibrous, biennial root, with an erect, smooth, quadrangular stem, with the angles winged, having many opposite branches, and growing from one to two feet in hight. The leaves are opposite, sessile, ovate, cordate at base, clasping the stem, five-veined, smooth, entire, and from one to two inches in length by half an inch to one and a half inches in width. The flowers are numerous, from an inch and a quarter to an inch and a half in diameter, of a rich rose color, terminal, on elongated peduncles, greenish or whitish in the center, and forming a large corymbose panicle. The calyx with five narrow, lanceolate, almost subulate segments, about half the length of the corolla; tube angular. Corolla with five obovate segments. Stamens five, erect, with short slender filaments and oblong anthers of a yellow color, which are spirally twisted after fecundation. The ovary is ovate, with a terete, declined, and bifid style, and the stigmas twisted spirally together. Capsule, one-celled, two-valved, many-seeded. History.—This plant is common to the Middle and Southern States, growing in low meadow grounds, and in wet seasons upon uplands, in woods and neglected fields, and flowering in July and August. The herb is employed, and should be collected when in flower. It has a strong bitter taste, and yields its virtues to water or alcohol. It is pref- erable to the European Centaury. Properties and Uses.—Tonic. Used as a prophylactic and remedy in autumnal intermittent and remittent fevers ; also useful in dyspepsia, and convalescence from fevers. When administered in warm infusion it is a domestic remedy for worms, and to restore the menstrual secretion.

Description.—Sugarcane is a herbaceous plant, with a jointed, succu- lent root, from which arise several shining, jointed, solid stems, one or two inches in diameter, from six to twelve feet in hight, colored yellow, 828 Materia Medica. greenish-yellow, purple, or striped, and containing a white juicy pith. The leaves are about three or four feet long, and an inch wide, flat, acuminate, longitudinally striated, furnished with a Avhite midrib, gla- brous, finely dentate, of a yellowish-green color, and originating at the joints of the stems which are about three inches apart, and at which places the stem is embraced by their lower portion. The panicle is terminal, spreading, erect, oblong, from one to three feet in length, and grayish from the quantity of long loose hairs surrounding the florets; the branches are alternate and very spreading. Rachis striated. Florets dicecious, in pairs. Glumes smooth. Paleai smooth, membranous, of a pink color. History.—The native country of sugarcane is unknown, though sup- posed to be indigenous to the south-eastern parts of Asia. Those canes which have not flowered, or have no tendency to flower, are the richest in sugar; and the lower part of them contains the greatest proportion. The juice constitutes nearly one-half of the cane, and when expressed, ferments rapidly, forming an acid, so that it requires to be promptly evaporated, and its acidity neutralized, before the sugar can be made. It has been analyzed a number of times, and is found to consist of crys- tallizable and uncrystallizable sugar, water, malic acid, gum, extractive, chlorophylle, etc. The sugar and molasses of commerce are obtained from the juice of this plant, and are prepared as follows: the ripe canes are cut down close to the ground, and with their tops and leaves removed, are crushed between vertical iron rollers. The juice thus obtained, con- stituting from fifty to ninety per cent., is of a pale-greenish color, sweet, with a balsamic odor, and a specific gravity from 1.033 to 1.106. The juice ferments quickly, and is therefore, at once conveyed from the vessels which have received it, into boilers, where every eight hundred parts of it are immediately mixed with about one part of milk of lime, or sufficient to render the liquor neutral, or very slightly alkaline, and heated to 140°. A thick scum forms on the top, consisting of albumen and gluten, and the liquid beneath is drawn off by means of a cock into a copper boiler, where it is sufficiently concentrated by ebullition, the scum being removed as it forms. If the juice be filtered, previous to the last boiling, it improves the sugar. When of the proper consistence, the concentrated juice is removed to shallow coolers, and again con- veyed, before cooling, into wooden vessels having perforated bottoms, with the holes temporarily plugged. As the sugar concretes, the liquid is stirred from time to time, which accelerates its granulation. When completed, the stoppers are removed from the holes, and the syrup is allowed to drain off. A yellowish, moist sugar is the result, which is further dried in the sun, and constitutes the brown sugar of commerce ; the liquid which is left, is again concentrated, and a further supply of sugar obtained, as well as of drainings, and which last is molasses. The brown sugar is formed into Havanna sugar by being again boiled with Saccharum Officinarum. 829 lime-water, sufficiently concentrated, placed in large inverted conical vessels, and, when sufficiently solid, covered with a thin mixture of clay and water, the latter of which percolates through the sugar, and removes the colored syrup through a small opening in the bottom of the vessel, rendering it of a whitish color. The sugar is still further purified by again boiling, filtering, clarifying, and placing it into molds, Avhere it is again clayed, and when all the syrup is removed, the sugar is placed in a warm oven to dry, and constitutes white or refined sugar. And by one or more repetitions of the process, is obtained single, double, and treble refined sugar. In clarifying the sugar, it is at first, while in the form of syrup, heated with bullock's blood, and then decolorized by passing it through a layer of coarse-grained animal charcoal, two or three inches thick. In the process of manufacturing sugar, a large proportion of it is lost, to prevent which several plans have been offered, but which have not, as yet, receiA'ed sufficient confidence to induce sugar-manufacturers to adopt them. Beside the sugarcane, sugar may be obtained from the beet, (Beta Vulgaris), and the sap of the sugar-maple, (Acer Saccharinum) and likewise from corn-stalks, turneps, onions, etc. In France considerable quantities are manufactured from the beet; and in Canada and the United States, wherever the sugar-maple tree grows abundantly, maple sugar, as it is termed, is largely made. A large quantity of sugar is also obtained from the sap of the cocoa-nut tree, ( Cocos Nucifera) as well as other species of palm growing in India. Other saccharine principles are recognized by the chemist, as Glucose, or Grape-sugar; this is not so sweet as canesugar, nor so readily soluble in water, but is much more soluble in alcohol. The crystallizable sugar of honey, starch sugar, and diabetic sugar are identical with it. It is hardly acted upon by concentrated mineral acids, which destroy cane- sugar with facility ; alkalies, which form definite compounds with cane- sugar, destroy grape-sugar. It undergoes very little change by long boiling with water, Avhich is apt to decompose cane-sugar, causing a loss in the amount of sugar obtained. Its solution rotates the plane of polar- ization of polarized light to the right, and is capable of undergoing the vinous fermentation immediately, Avithout passing through any interme- diate state. Its specific gravity is 1.386, and its formula C12 Hit Oh. Uncrystallizable or Fruit-sugar, called by Souberain, Chulariose. This is found in honey, and in the juice of fruits, and may be obtained from cane-sugar by solution in water or Aveak acids, and long boiling. A watery solution of this sugar turns the plane of polarization to the left, and is as susceptible of the vinous fermentation, without intermediate change, as the grape-sugar. Its formula, when dried at 212°, is C12 H12 O12. Lactin or Sugar of Milk, see Saccharum Lactis. Sugar of Ergot, obtained by Wiggers from ergot of rye, is soluble in water and alco- hol, crystallizes in transparent rhombic prisms, and is susceptible of the 830 Materia Medica. vinous fermentation. Its formula is given as C12 H13 O13. For a descrip- tion of the other saccharine principles, mannite and glycerin, see articles Manna and Glycerina. Sugar has been known from the earliest ages, and was used in Europe exclusively as a medicine, from the time of its introduction, about the period of the Crusades, until the cultivation of the sugar-cane in the New World, when it soon became a common article of food throughout the civilized world. The greater part of the sugar of commerce at this day, is manufactured in the West Indies, and some of the Southern United States. In the United States, a variety of sugar-cane, called the Otaheite-cane, has recently been introduced; it is said to be hardier, more productive, and better suited to the climate of the Southern States. The first concretion of the juice of sugar-cane, as before remarked, gives rise to brownish crystalline grains, and a thick, empyreumatic syrup, called molasses, Sacchari Fcex, or Sacchari Syrupus Empyreu- maticus. Of this, there are two varieties, the West India and Sugar- House. The West India Molasses is a black ropy liquid, of a peculiar odor, and a sweet empyreumatic taste. When mixed with water and the skimmings of the vessels used in the manufacture of sugar, it forms a liquor, which, when fermented and distilled, yields rum. Sugar-house Molasses is the officinal one, it is thicker than the West India, about the same color, with a peculiar, sweet, rather pleasant taste, differing in flavor from the former ; it consists chiefly of gummy extract and uncrys- tallizable sugar, and thickens very slowly under exposure to the air. Its specific gravity is 1400. The grains constitute the brown sugar, raw sugar, or muscovado sugar of commerce, Saccharum Commune, (Saccharum non Purificatum); six or eight pounds of the juice yield one pound of raw sugar, and this when purified is the refined loaf, or white sugar, Saccharum Purum. Raw sugar, of good quality, is in small shining grains, which are short, broken, four-sided prisms varying in color from very pale yellowish-gray, to rather deep yellowish-brown, dry when recent, but afterward some- what clammy, of a purely sweet taste, and of a feeble honey-like odor. Pure Sugar is usually prepared in compact, crystalline, conical loaves, which are snow-white, dry, easily pulverizable, inodorous, of an intense sweet taste, without any aroma, permanent in the air, phosphorescent by friction, and of a specific gravity from 1.5629 to 1.6. It crystal- lizes in oblique, four-sided prisms, terminated by two converging planes, or in derived figures, in which form it contains 5.3 per cent, of Avater of crystallization. When heated to 365°, it melts into a viscid, colorless liquid, which on being suddenly cooled, forms a transparent amorphous mass, called Barley-sugar; between 400° and 420°, it loses two equivalents of water, swells, emits a peculiar odor, and is converted into a black porous mass, having a high luster, like anthracite, called Saccharum Officinarum. 831 Caramel. At a still higher temperature, it yields combustible gases, car- bonic acid, empyreumatic oil, and acetic acid, leaving about one-fourth its weight of charcoal, which burns without residue. Sugar is soluble in twelve parts of rectified spirit and in eighty parts of alcohol; it dissolves readily in half of its weight of temperate water, and to an almost un- limited extent in boiling water, which solution, when thick and ropy, is called Simple Syrup, Syrupus Simplex. The fixed and volatile oils are to a certain extent rendered miscible with water by means of sugar, with the volatile oils it imperfectly combines, forming the Oleum-saccharum of the pharmaceutist. Sugar may be distinguished from most other organic principles, by not being precipitated by subacetate of lead, when in solution. Strong nitric acid, with the aid of heat, converts sugar into oxalic acid ; and when weak, into saccharic acid. Chlorine converts it into saccharic acid. Concentrated sulphuric or muriatic acid chars it; diluted muriatic acid, converts it into a solid, brown* gelatinous mass, by boiling. Diluted sulphuric acid changes it into uncrystallizable sugar, then into grape sugar*and ultimately into sacchulmin, which is insolu- ble, and sacchulmic acid, which is soluble in ammonia. Sugar in fine powder, treated with a mixture of sixteen parts of sulphuric and eight of nitric acid, and cooled to the temperature of 60°, is converted, in a few seconds, into a pasty substance, which, after having being washed in cold water and dissolved in alcohol, furnishes, on the addition of an excess of carbonate of potassa to the alcoholic solution, a peculiar explo- sive and inflammable substance, resembling common rosin in its physical properties, and, like it, insoluble in water, but soluble in alcohol, ether, and the volatile oils. Oxalic, tartaric, citric, malic, and acetic acids, prevent sugar from crystallizing from its watery solution, effecting changes in it similar to those resulting from the action of mineral acids. If sugar be boiled in open vessels with weak sulphuric acid, for several days, oxygen will be absorbed, and formic acid will be generated with sacchulmin and sacchulmic acid. Sugar combines with the alkalies, losing its sweet taste, and forming compounds which render the sugar less liable to change; it likewise unites with various metallic oxides rendering them soluble. Boiled for a long time with aqueous solutions of potassa, lime, or baryta, the liquid becomes brown, formic acid is pro- duced, and melassic and glucic acids are generated; the former being brown or black, and insoluble in water, the latter colorless and very soluble. When distilled with lime, sugar yields a volatile liquid called acetone, and an oily substance termed Metacetone. Properties and Uses.—Sugar is nutritive, alterative, demulcent, and topically antiseptic. It cannot sustain life alone, owing to the absence of nitrogen in its composition, and only becomes eminently nutritive when combined with other alimentary proximate principles. Used in large quantities it is injurious to digestion. In relation to both vegetable and animal matters it is a powerful antiseptic ; the former of which may be 832 Materia Medica. preserved indefinitely in syrup, so long as the syrup is secured against fermentation; while the latter, after long immersion in syrup, or in moistened sugar, may be perfectly mummified. On this account it is now used considerably in preserving fish and meat, instead of salt, to which it is superior, as it requires a less quantity of sugar than salt, and does not change the taste nor injure the nutritive qualities of the aliment. Sugar or molasses, when freely eaten by children, prove excellent anthel- mintics ; it has proved beneficial in scurvy, and in some chronic cutane- ous diseases, and powdered loaf sugar has been applied externally to fungous ulcers, and for the removal of specks on the cornea. It has long been a popular idea that sugar is injurious to the teeth, this, how- ever, is erroneous ; if particles of sugar become lodged between the teeth, and are allowed to decompose, decay will inevitably ensue, but if the particles be removed at an early period, sugar will be found to exert a beneficial influence upon the teeth and gums. As a demulcent, sugar has been used in various forms in catarrhal affections; and when it is used daily in very large quantities, say a pound or more dissolved in a quart of cold water, it is said to be powerfully antiphrodisiac. The use of it, however, is mainly confined to the preparation of syrups, to cover the taste of nauseous drugs, for rendering oils miscible with water, for suspending many drugs in the form of mixture or emulsion, to pro- tect certain ferruginous preparations from oxidation, and also for con- Alerting some agents into the state of conserve, confection, electuary, pill, or lozenge. For pills, molasses is most generally preferable to syrup, as it does not so readily harden, and preserves them in a soft, moist state, for a long time, Avhile its antiseptic properties prevent them from becom- ing moldy. Sugar may be detected in urine by the liquid fermenting on the addi- tion of yeast; or by yielding a reddish-brown precipitate when boiled with a solution of sulphate of copper, and solution of caustic potassa; boiled with solution of potassa alone, it acquires a dark-broAvn or bistre tint. Dr. Donaldson gives the folloAving simple and easy method for dis- covering the presence of sugar in the blood, urine, or bile : Take of crystallized carbonate of soda, and caustic potassa, of each, five parts, bitartrate of potassa six parts, crystallized sulphate of copper four parts, distilled Avater thirty-two parts; mix together, boil, and filter. A few drops of this solution, thrown into urine or other liquid suspected of being saccharine, and heated over a spirit-lamp, will discover the small- est quantity of sugar present. After a few minutes' application of heat, the liquid acquires first a yellowish-green color, and becomes more and more reddish-yellow, as the proportion of sugar is more considerable. Sugar in solution absorbs a very large quantity of lime. A saccharale of lime has been found very beneficial in the chronic diarrheas of child- ren, as well as to prevent acidity of the stomach, and the disposition to diarrhea so common in children of a certain age at particular seasons. Saccharum Lactis—Sagapenum. 833 It is made by saturating simple syrup with lime, and then filtering it; it forms a transparent mixture of an extremely alkaline taste, and may be added to water or milk. It is altogether superior to the bicarbonate of soda. Dose for an infant, from a fourth to half a drachm, given in some of the mother's milk ; for an adult, from one drachm to two and a half. Off.

For further purification, use animal charcoal, and repeated crystallizations. History.—Sugar of Milk is a white, gritty, crystalline, semi-transpa- rent substance, permanent in the air, soluble in five or six parts of cold water, and two and a half or three of boiling water, Avithout forming a syrup, and insoluble in alcohol or ether. It is inodorous, feebly SAveet, but much more so in a concentrated solution, and of the specific gravity 1.54. It is frequently met with in cylindrical masses, in the axis of which is a cord, around which the crystals have been deposited. When converted into grape-sugar by the action of diluted acids, it is susceptible of vinous fermentation, and affords an intoxicating spirituous liquor. Mucic acid is formed by* the action of diluted nitric acid upon it. Its formula is C21 Hu Oi9-r-5HO ; and when anhydrous C24 Hio 0.9. Properties and Uses.—Its principal medicinal use is in the trituration of drugs; to aid in rendering them finer and more energetic, as well as to assist in more easily dividing active agents which are to be given in minute doses : thus, if we wish to divide one grain of strychnia into twenty doses, it may be thoroughly triturated with nineteen grains of sugar of milk, and one grain of the mixture gives the required dose. Or, one grain of podophyllin, which, in general, is a cathartic dose, by long trituration Avith ten grains of sugar of milk, will form several pur- gative doses. In these cases, the trituration should always continue for from one hour to an hour and a half. As a medicinal agent Sugar of Milk is inert. SAGAPENUM. Sagapenum. the gum-resin of an uncertain plant. History.—This gum-resin is brought from Alexandria, Smyrna, and other parts of the Levant. It is the concrete juice of a plant growing 53 834 Materia Medica. in Persia, the history of which is not fully known. It is in irregular masses, composed of agglutinated fragments, slightly translucent, of a brownish-yellow, olive, or reddish-yellow color externally, paler inter- nally, brittle, in consistence resembling wax, with an alliaceous odor, and a hot, nauseous, bitterish taste. It softens and becomes tenacious by the heat of the hand. It is almost entirely soluble in diluted alco- hol. A«-e and exposure harden it as well as render it darker. It is inflammable, burning with a white flame and considerable smoke, and leavino- a lhdit spongy charcoal. An inferior kind is browner, softer, and uniform, Avithout any appearance of tears. It consists of resin, gum, bassorin, volatile oil, salts, etc. The oil is pale-yellow, very fluid, lighter than water, and of an intense alliaceous odor. Properties and Uses.—Gentle stimulant, antispasmodic, and emmena- gogue ; inferior to assafetida. Occasionally employed externally as a discutient, in the form of plaster, to indolent tumors. Dose from ten to thirty grains, in pill or emulsion. SAGUS RUMPHII. Sago. Nat. Ord.—Palmaceae. Sex. Syst.—Moncecia Hexandria. THE PREPARED FECULA OF THE PITH. Description.—The Sagus Rumphii, or Sago Palm, is one of the small- est trees of the family to which it belongs, seldom exceeding thirty feet in hight. The trunk is, proportionably, very thick, quite erect, cylindri- cal, covered with the remains of the old leaf-stalks, and surrounded by a beautiful crown of foliage, consisting of numerous, very large, pinnate leaves, extending in every direction from the summit, and curving grace- fully downward. From the basis of the leaves proceed long, divided and subdivided fiowers, and fruit-bearing spadices, the branches of which are smooth. The fruit is a roundish nut, covered with a checkered imbricated coat, and containing a single seed. History.—This tree is a native of Malacca, and the adjacent islands, thriving in low and moist situations. Previous to maturity, the trunk consists of an external ligneous part about two inches in thickness, and an internal spongy medullary substance, somewhat like the pith of elder. After the appearance of fruit; this internal substance is gradually absorbed, and the trunk eventually becomes hollow. The maximum age of the tree does not exceed thirty years. There are two other species of palm known to produce sago, namely : Sagus Lmvis, Jack, or Sagus Inermis, Roxburgh, a native of Borneo and Sumatra ; and Sagueris Rumphii, abounding in all the eastern isles of the Indian Ocean. These, with the Sagus Rumphii, contain a farinaceous pith, and probably fur- nish the finest kinds of sago. Sago has likewise been obtained from the Sagus Rumphii. 835 Sagus Ruffia, Phoenix Farinifera, Cycas Revoluta, Cycas Circinalis, Zamia Lanuginosa, and Caryota Urens. As soon as the pith or medullary matter has become fully developed, the tree is cut down, and the pith extracted. This is then reduced to a coarse powder, and stirred with water; the water is allowed to stand until the starch has subsided, and is then strained off; the remaining amylaceous matter is then made into cakes, dried, and used by the na- tives as food, under the name of Meal Sago. When made into a paste with water, and rubbed into grains, it forms the Granular Sago of com- merce. Sago is abundantly manufactured in the Moluccas, but the finest quality is obtained from the eastern coast of Sumatra. In several places it is refined by some process not yet satisfactorily ascertained, and which gives the grains a fine pearly luster. In this state it is called Pearl Sago. A single tree, it is stated, will yield from five to six hun- dred pounds of sago. Sago Meal is rarely met with in this country, though imported into England. It is in the form of a fine amylaceous powder, of a pale yel- lowish-Avhite, or reddish-white color, of a feeble, somewhat musty, peculiar odor, and composed of unbroken starch globules. Under the microscope it is found to consist of oval or ovate particles, many of which appear as if truncated, so as to be more or less muller-shaped. They are generally more or less broken, and the surface of the greater part of them is irregular or tuberculated. Their surface exhibits con- centric rings, which, however, are not so distinct as in the potato-starch. The hilum is circular when perfect, and cracks either with a simple slit, a cross, or in a stellate manner. Common Sago is in roundish grains of the size of pearl-barley, or sometimes larger, mottled with various tints of gray and brown, and composed of aggregated, unbroken globules. Under the microscope, their appearances are similar to those of the sago meal, except that they are less regular, and more broken. The above varieties do not yield any soluble starch or amidin to cold water. Pearl Sago is the kind most generally used, and is the most esteemed. It is in pale yellowish-white, reddish-white, grayish-white, or translucent grains, about the size of a pin's head, inodorous, nearly tasteless, of a somewhat pearly luster externally, and forms a solution with cold water which is rendered blue by tincture of iodine. A solution of chloride of lime will render it perfectly white. Its partial solubility in cold water, is, probably, owing to the action of heat used in preparing it. It pos- sesses the chemical properties of starch. Under the microscope, the granules are of the same form as in the preceding, but are all ruptured, and exhibit very indistinct traces of the external concentric rings, which have been, undoubtedly, altered in the process employed in their preparation. Common Sago is insoluble in cold water, but upon being boiled, it becomes at first soft and transparent, and ultimately forms a gelatinous 836 Materia Medica. solution. Pearl sago is more soluble. Imitation pearl sago, prepared from potato-starch, may be known by exhibiting larger granules under the microscope, which are more regularly oval or ovate, smoother, less broken, and more distinctly marked with the concentric rings on their surface; and when cracks occur at the hilum, they are usually in two diverging fissures. Properties and Uses.—Sago is nutritive and demulcent, and is a con- venient and agreeable article for making puddings, gruel and diet drinks for the sick room. It should always be long boiled before it is used. It is not so much used as formerly, being superseded by the purer arrow- root and tapioca. A tablespoonful of sago to a pint of water, is sufficient for ordinary purposes ; and the solution may be sweetened with loaf- sugar, and seasoned Avith nutmeg or other spice, wine, etc., when these are not contra-indicated. Castillon's Powders, a popular article of diet for invalids, in cases of indigestion, chronic dysentery, etc., is composed of Sago, Salep, Traga- canth, of each, in powder, four drachms, powdered prepared oyster- shells one drachm. These are to be well mixed, and divided into twelve powders ; sometimes it is colored with a small quantity of cochineal. For use, each powder is to be boiled with a pint of milk ; which may be sweetened and flavored to suit the patient's taste. SALIX ALBA. Willow. Nat. Ord.—Salicaceae. Sex. Syst.—Dicecia Diandria. THE BARK. Description.—Salix Alba, or White-willow is a tree from thirty to eighty feet in hight, Avith numerous round, widely spreading branches, the younger of which are silky. The bark is brown, thick, and full of cracks ; that of the smaller branches smooth and greenish. The leaves are alternate, on short petioles, lanceolate, or elliptic-lanceolate, broadest a little above the middle, pointed, tapering toward each end, acutely serrate with the lower serratures glandular; both sides of a grayish, somewhat glaucous, green, beautifully silky, with close-pressed silvery hairs, especially on the under surface, and which is very dense and brilliant on the uppermost, or youngest leaves ; the lowermost on each branch, like the bracteas, are smaller, more obtuse, and greener. The stipules are variable, either roundish or oblong, small, and often wanting. The fiowers appear at the same time with the leaves. The aments are on 6hort stalks, with three or four spreading, leafy bracteas, terminal, cylin- drical, and elongated. Scales brown, elliptical, lanceolate, pubescent at the margin; those of the barren aments narrower toward the base ; of the fertile, dilated and convolute in that part. Stamens two, yellow, Salix Alba. 837 rather longer than the scales, with one obtuse gland before, and one behind ; filaments hairy in their lower part. Anthers roundish, yellow. Ovary very nearly sessile, green, smooth, ovate-lanceolate, bluntish, longer than the scale. Style short; stigmas short, thick, two-parted, recurved, and nearly sessile. Capsule ovate, brown, smooth, rather small. History.—The White or European Willow has been introduced into this country from Europe, and is now very common. It flowers in April and May ; and the bark is easily separable throughout the sum- mer. When dried it rolls up into quills, having a brown epidermis, and being flexible, fibrous, and of difficult pulverization. It has a feebly aromatic odor, and a peculiar, bitter, astringent taste. Water extracts its active properties, and the decoction is of a reddish-brown color. Willow bark contains a large proportion of tannin, a bitter yellow coloring matter, a green fatty matter, gum, wax, lignin, an organic acid com- bined with magnesia, and a crystalline principle, named Salicin. There are not less than one hundred and thirty species comprised in this genus, which chiefly abound in the northern and temperate parts of Europe and America; and probably all of them are possessed of similar medical properties in a greater or less degree. The best method of determining the value of the various species, is, probably, by the degree of bitterness in the bark. Among those which have been used, are the S. Alba, S. Caprea, S. Fragilis, S. Russelliana, S. Purpurea, and S. Pentandra. The Weeping Willow or Babylonian Willow, Salix Baby- lonica, is cultivated as an ornamental tree. Properties and Uses.—Willow-bark is tonic and astringent, and has been employed as a substitute for Peruvian bark in intermittent fever, to which, however, it is inferior. In chronic diarrhea and dysentery, the tonic and astringent combination of the willow, renders it very eligible. It may be given in substance, in doses of one drachm of the powder, repeated as indicated ; or of the decoction, one or two fluid- ounces, four or five times a day. The decoction has also proved effica- cious as a local application to foul and indolent ulcers. Salix Nigra, Black, or Pussy Willow, is a tree growing from fifteen to twenty-five feet high, covered with a rough blackish bark, and found on the banks of rivers, especially in New York and Pennsylvania. The leaves are narrowly lanceolate, pointed and tapering at each end, serru- late, smooth and green on both sides; petioles and midveins tomentose. The stipules are small, deciduous, dentate; aments erect, cylindric, villous ; scales oblong, very villous, Sterile aments three inches long; glands of the sterile flowers two, large, and deeply two or three cleft. Stamens four to six, often but three in the upper scales; filaments bearded at base. Ovary pedicellate, smooth, ovoid ; style very short; stigmas bifid. The branches are pale yellow, and brittle at base, and are 838 Materia Medica. much used for the manufacture of baskets and other kinds of wicker- work. The bark of black or pussy willow, is recommended as a poultice in gangrene, and as an external application to foul and indolent ulcers, in which it stands unrivaled. It is made by simmering the powdered bark in cream. It has also been successfully used in various swellings of the neck. Internally, the root is a bitter tonic, effectual in intermittents. Some have highly recommended it in asthma and gout. A decoction of the black willow buds or aments is useful in gangrene, taken internally, and applied locally; and drank freely it proves a pow- erful anaphrodisiac, suppressing venereal desires for a long time, and is highly recommended in the treatment of spermatorrhea. SALICIN. Salicin. THE ACTIVE PRINCIPLE OF THE WILLOW. Preparation. — Several processes are given for the preparation of Salicin. Merck obtained 251 grains from sixteen ounces of the bark and young twigs, by the following process : Treat a boiling concentrated decoction of the bark with litharge, until it becomes nearly colorless; this removes the gum, tannin and extractive from the liquid, the presence of which would impede the crystallization of the salicin, while at the same time a portion of the oxide is dissolved, probably in union with the salicin. To separate this portion of oxide, sulphuric acid is first added, and then sulphuret of barium, and the liquor is filtered and evaporated. Salicin is deposited, and may be purified by repeated solution and crys- tallization. Erdmann obtained 300 grains of salicin, from sixteen ounces of the bark of Salix Pentandra. Sixteen ounces of the bark are mace- rated for twenty-four hours in a mixture of four quarts of water, and two ounces of lime, and the whole is then boiled for half an hour. This process is repeated twice with the residue. The decoctions are mixed, allowed to become clear by subsidence, the liquor poured off, and con- centrated to a quart; this concentrated liquid is then digested with eight ounces of ivory-black, filtered, and evaporated to dryness. The extract in powder is then exhausted with spirit containing 28 per cent. of alcohol, and the tincture evaporated, or the spirit distilled off, so that the salicin may crystallize. It may be purified by again dissolving, treating with ivory-black, and crystallizing. Another method is as follows:—Willow-bark is boiled with caustic lime in water; the decoction is filtered, and sulphate of zinc added so long as it produces a precipi- tate. The liquid having been again filtered, is evaporated to the con- sistence of an extract, and the residue is treated with alcohol. The tincture thus obtained, if carefully evaporated, yields crystals of salicin, which may be purified by washing with a saturated solution of the same principle in cold water. Salvia Officinalis. 839 History.—Salicin, when pure, is white, forming minute, shining, rect- angular crystals, permanent in the air, inodorous, of a persistent bitter taste with the peculiar aromatic flavor of the bark, soluble in twenty parts of temperate water, and also soluble in alcohol, but insoluble in ether or oil of turpentine. It is a neutral body and is not precipitated by any reagent. Concentrated sulphuric acid decomposes it, forming a new compound of a permanent bright-red color, called Rutulin. Dis- tilled with bichromate of potassa and sulphuric acid, it yields formic and carbonic acids, hyduret of salicyle, and a resinous matter. Hyduret of salicyle, or salicylous acid, is an oily colorless liquid, having a fragrant aromatic odor, and a burning taste. Its specific gravity is 1.1731, it boils at about 380°, and its formula is Cu Hs 04, H=Sa H. With bases it forms salicylurets, water being separated. It may be obtained by distilling one part of salicin, one part of bichromate of potassa, two and a half parts of sulphuric acid, and twenty parts of water, together. The salicin is dissolved in part of the water, and the acid diluted with the rest. The mixture is then made in a retort, and after the effer- vescence which takes place is over, the whole is distilled, and yields the hyduret, to the amount of one-fourth of the salicin employed. By con- tact with synaptase, salicin is decomposed, being resolved into grape- sugar and a new body called Saligenine; this latter, boiled with a diluted acid, or heated beyond its melting point, is changed into a white, tasteless, insoluble, resinous powder, named Saliretin. The formula of salicin is C26 His Ou. Properties and Uses.—Salicin is tonic, antiperiodic, and febrifuge ; and may be used as a substitute for quinia, to which, however, it is slightly inferior. It is, however, less likely to offend the stomach and affect the nervous system, for which properties it may be administered in cases where cinchonism would be produced by the exhibition of quinia. It is often employed to adulterate quinia with, and may be detected by sulphuric acid, which will turn the Salicin red, even in minute quantity. The dose of salicin is from two to ten grains to be repeated three or four times a day; three doses of six grains each, have been known to cut short intermittent fevers in one day. Off.

Description.—Salvia Officinalis or Garden Sage is a perennial, shrubby plant, about two feet in hight, with a quadrangular, pubescent, branch- ing stem. The Imves are opposite, petiolate, ovate-lanceolate, crenulate, 840 Materia Medica. wrinkled, of a grayish-green color, sometimes tinged with red or purple; the loAvermost tomentose beneath. The fiowers are blue, variegated with white and purple, and arranged in long, terminal spikes, composed of distant whorls, each composed of few flowers, and accompanied with sessile, ovate, acuminate and deciduous bracts, which are membranous and striated at the base. The calyx is campanulate, membranous, colored, striated, downy, and bilabiate; the upper lip is three-toothed, the lower bifid; all the teeth subulate, acuminate. The corolla is two or three times as long as the calyx, with a large projecting tube, ringed in the inside, and bilabiate; the upper lip is arched and concave, and the lower one divided into three rounded lobes, of which the middle is the largest, the lateral ones reflexed. The stamens are affixed to short pedicels transversely about their middle. History.—Sage is indigenous to the South of Europe, and is exten- sively cultivated in gardens in this country, where it flowers in June, at which time the leaves and tops which are officinal, should be collected, and dried in a shady place. They have a strong, fragrant odor, and a warm, bitterish, aromatie, somewhat astringent taste, which are due to the presence of an abundance of volatile oil containing considerable camphor, and which may be obtained by distillation with water. It imparts its virtues to boiling water in infusion, but more readily to alco- hol. The infusion becomes black on the addition of sulphate of iron. Numerous other species have similar properties as the S. Sclarea or Clarry, a native of Southern Europe, which is said to be antispasmodic and balsamic. Also the S. Horminum, S. Bengalensis of India, S. Pomifera of Greece, etc. Properties and Uses.—Sage is feebly tonic and astringent, expectorant, diaphoretic, and having properties common to aromatics. An infusion is beneficial in flatulence connected with gastric debility, and will, it is stated, prove efficacious in checking the exhausting sweats of hectic fever; it may likewise be used warm, as an anthelmintic, and for the purpose of causing diaphoresis in some febrile diseases. The warm infusion will cause active diuresis by checking its diaphoretic tendency. Dr. James Anton of Georgia, considers it an excellent remedy for sperma- torrhea ; also a valuable antiphrodisiac to check excessive venereal desires. It may be used in connection with moral, hygienic, and other aids, if necessary. Van Swieten states that a vinous infusion forms an excellent fomentation to the breasts of nurses, when it is desirable to check the flow of milk. The infusion is much used as a gargle for inflammation and ulceration of the throat, and relaxed uvula, either alone, or combined with vinegar, honey, alum, or sumach berries. The oil may be used in small doses as a carminative and stimulant; and externally, applied with friction in rheumatism. Dose of the infusion, from two to four fluidounces, three or four times a day; of the powdered leaves, twenty to thirty grains. Sambucus Canadensis. 841 Salvia Lyrata, variously named Wild or Meadow Sage, Lyre-leaved Sage, or Cancer Weed is a perennial plant, growing from Canada to Florida in shady woods and meadows, and flowering in May and June. It has an erect quadrangular, nearly leafless stem, one or two feet high, branch- ing above and covered with hairs pointing downward. The radical leaves are obovate, lyre-shaped or sinuate-pinnatifid, sometimes almost entire, and petiolate; the cauline leaves mostly but one or two pairs, just below the raceme, smaller and narrower than the radical. The flowers are blue, in loose and distant whorls of about six, forming a long, interrupted raceme; bracts oblong-linear, not longer than the calyx. The upper lip of the blue-purple pubescent corolla, short, straight, not vaulted ; the tube much exserted. The fresh radical leaves of this plant will, it is positively asserted, when bruised, and applied to Avarts, generally destroy them; the application to be continued for a day or two, and renewed every twelve hours. It is also reputed to have cured cancers. Off. Prep.—Infusum Salviae Compositum. SAMBUCUS CANADENSIS. Elder. Nat. Ord.—Caprifoliaceas. Sex. Syst.—Pentandria Trigynia. THE FLOWERS AND BERRIES. Description.—Sambucus Canadensis is an indigenous shrub from six to ten feet high, with a branching stem, which is covered with a rough gray bark, and contains a large spongy pith. The small branches and the leafstalks are very smooth. The leaves are opposite, pinnate, sometimes bipinnate, and generally composed of three or four pairs of leaflets, with an odd one, and which are oblong-oval, serrate-acuminate, smooth, shining, deep-green, with the midribs somewhat pubescent; the lower ones are often trifoliate. Petioles smooth. The flowers are small, Avhite, and disposed in loose cymes, which are level-topped and five-parted. The fruit consists of numerous small, globular berries, which are of a dark-purple color when ripe. Sambucus Nigra or European Elder, is larger than the preceding, approaching in size to that of a small tree. The stem is much and irregularly, though always oppositely branched, and of quick growth ; after a year's growth the branches become filled with a light spongy pith, and covered with a smooth gray bark. The bark of the stem is rough and whitish. The leaves are long, and composed of two opposite pairs of leaflets and an odd terminal one, which are oval, acuminate, serrate, smooth, and of a shining green color. The flowers are small, numerous, cream-colored, and form large five-parted cymes; the calyx is persistent, five-cleft; the corolla rotate, five-cleft, with obtuse and somewhat reflexed segments. The stamens are five, subulate, as long 842 Materia Medica. as the corolla, and furnished with roundish, cordate, yellow anthers. The ovary is ovate, supporting three obtuse stigmas. The fruit is a globu- lar berry, of a purplish-black color when ripe, on a reddish footstalk. History.—Sambucus Canadensis is an indigenous shrub growing in all parts of the United States, in low moist grounds, thickets, and waste places, flowering from May to July, and maturing its berries early in the autumn. S. Nigra is indigenous to many parts of Europe, growing in situations similar to those of the American variety. The two plants possess similar medical properties. The officinal parts are the flowers, the berries and the inner bark. The flowers have a peculiar sweetish odor, very strong when recent, but feeble when dried; they are somewhat aromatic, with a bitterish taste, and yield their properties to hot water in infusion. The active principle probably depends upon a volatile oil, which is dissipated by boiling, but which maybe obtained by distillation with- water; when cold it has the consistence of butter. Water distilled from the flowers contains ammonia in appreciable quantity. They contain volatile oil, acrid resin, tannin, extractive, etc. The berries are nearly inodorous, with a sweetish, acidulous taste; the juice expressed from them is susceptible of fermentation, and forms , a vinous liquor. It is of a purplish color, and may be used as a delicate test for acids and alkalies. Acids color it bright red, and alkalies violet; and acetate of lead precipitates its coloring principle blue. The berries contain malic acid, a little citric acid, sugar, pectin, and coloring matter. The inner bark is greenish-white, inodorous, of a sweetish taste at first, but subsequently slightly bitter, acrid, and nauseous, and imparts its properties to water or alcohol. Its active principle is stated by Simon to be a soft resin, which may be obtained by exhausting the powdered bark with alcohol, filtering the tincture, evaporating to the consistence of syrup, then adding ether, which dissolves the active matter, and finally evaporating to the consistence of a thick extract. Twenty grains of this will purge and vomit actively. The bark contains valerianic acid, traces of volatile oil, resin, albumen, an acid sulphurous fat, wax, chloro- phylle, tannic acid, grape-sugar, gum, extractive, starch, pectin, and various salts. Properties and Uses.—In warm infusion the flowers are diaphoretic, and gently stimulant; in cold infusion they are diuretic, alterative, and cooling, and may be used in all diseases requiring such action, as in hepatic derangements of children, erysipelas, erysipelatous diseases, etc. In infusion with maidenhair and beech-drops, they will be found very valuable in all erysipelatous diseases. The expressed juice of the berries, evaporated to the consistence of a syrup, is a valuable aperient and alter- ative ; one ounce of it will purge. An infusion of the young leaf-buds are likewise purgative, and sometimes act with violence. The flowers Sanguinaria Canadensis. 843 and expressed juice of the berries have been beneficially employed in rheumatic, gouty, eruptive, scrofulous, and syphilitic diseases. The inner green bark is cathartic; an infusion of it in wine, or the expressed juice will purge moderately, in doses of from half a fluidounce to a fluid- ounce ; large doses produce emesis; in smaller ones it proves an effica- cious deobstruent, promoting all the fluid secretions, and is much used in dropsy, especially that following scarlatina, and other febrile and exanthematous diseases, as well as in many chronic diseases. Beaten up with lard or cream, it forms an excellent discutient ointment, and which is of much value in burns, scalds, and some cutaneous diseases. The juice of the root in ounce doses, daily, acts as a hydragogue cathar- tic and diuretic, and will be found valuable in all dropsical affections. Off.

Description.—Bloodroot, or Red Puccoon, as it is sometimes called, is a smooth, herbaceous, perennial, indigenous plant, with a horizontal, truncate or premorse root or rhizoma, giving off a few fibers, and abound- ing in a bright-orange juice ; it is about as thick as the finger, two or three inches long, fleshy, reddish-brown externally, and brighter red internally. From each bud of the root-stalk there springs a single, large, smooth leaf, and a scape about six inches high, with a single flower; and as they arise, the folded-leaf envelops the flower-bud, and rolls back as the latter expands. The leaf is erect, supported on a long channeled petiole, cordate or subreniform, with large roundish lobes separated by obtuse sinuses, yellowish-green on the upper surface, paler on the under, and strongly marked by orange-colored veins. The scape is erect, round, and smooth. The flower is white, scentless, of a quadrangular outline, and of short duration. The calyx formed of two concave, ovate, obtuse sepals, which fall off as soon as the corolla expands; the corolla is composed of eight (or more, by cultivation) petals, which are spreading, ovate, obtuse, concave, white, but some- times slightly tinged with rose or purple. The stamens are numerous, short, with oblong, orange-colored anthers. The ovary is oblong, and compressed, and supports a sessile, persistent, somewhat two-lobed stigma. Style wanting. The capsule is oblong, acute at each end, tAvo- valved, and contains numerous, obovate, dark shining red seeds, half surrounded by a white arillus. The whole plant is pervaded with an acrid orange-colored juice, which is in greatest abundance in the root. 844 Materia Medica. History.—Bloodroot is found in most parts of the United States, grow- ing in woods, groves, and on shaded banks, in rich light soil; it is one of the earliest and most beautiful spring-flowers of this country, appear- ing in March and April. When dried, bloodroot is in pieces from one to three inches in leno-th, from three to nine lines in thickness, somewhat flattened, much wrinkled and twisted, often furnished with abrupt oftsets and numerous short fibers, of a reddish-brown color externally, with a spongy, uneven fracture, and of a bright-orange color internally, but which becomes dull brown by long exposure. It forms a brownish orange-red powder. It has a faint virose odor, and a bitterish, very highly and persistently acrid taste. It imparts its properties to boiling water or alcohol. The root should be kept in a dry place; age or mois- ture impairs its activity. An alkaloid and resinoid are prepared from the root, the former termed Sanguinarina, the latter Sanguinarin. Properties and Uses.—Bloodroot is an acrid emetic, with narcotic and stimulant properties ; it is also expectorant, sudorific, alterative, emmena- gogue, tonic, antiseptic, detergent, escharotic, and errhine, according to the mode in which it is employed. It is a very active agent, and is capable of exercising a powerful influence on the system. When given in small doses it stimulates the digestive organs, and accelerates the cir- culation ; in larger doses, it occasions nausea and consequent depression of the pulse; and in a full dose, it produces active vomiting. In over- doses it causes violent emesis, a burning sensation in the stomach, tormenting thirst, faintness, vertigo, dimness of vision, alarming pros- tration, and even death. It has been successfully used in pulmonary and hepatic affections, catarrh, croup, pertussis, typhoid pneumonia, rheumatism, jaundice, dyspepsia, and hydrothorax, either as an emetic, nauseant, or alterative. In torpid conditions of the liver it is very valu- able, and it has also proved beneficial in scrofula, amenorrhea, and dysentery. Used as a snuff, either alone or combined with bayberry bark, it is beneficial in coryza, some headaches, and is recommended as a remedy for nasal polypus. Applied to fungous growths, indolent and ill-conditioned ulcers, and fleshy excrescences, the powder often proves of utility, removing the fungous growth by its escharotic action, and creating a new and healthy energy in the ulcers. An infusion made in vinegar has been found valuable in several obstinate cutaneous diseases, tetter, ringworm, and warts. Dose of the powder, as an emetic, from ten to twenty grains; of the tincture, from twenty to sixty drops; as a stimulant or expectorant, from three to five grains; as an alterative, from half a grain to two grains. It may be used in powder, pills, tincture, or extract. Off.

SANGUINARINA. Sanguinarina. THE ALKALOID PRINCIPLE OF BLOODROOT. Preparation. — Digest six ounces of finely powdered bloodroot in twelve ounces of diluted muriatic or acetic acid; at the expiration of ten days, filter, and add to the filtered tincture two and a half ounces of aqua ammonia, and pour the mixture into a vessel containing tAvo pints of distilled water; filter and collect the brown matter which subsides, and carefully wash it with a small quantity of distilled water, and remove the coloring by means of purified charcoal. Then treat it with boiling alcohol, which dissolves the sanguinarina, and cautiously evaporate. Or it may be prepared by forming a strong ethereal tincture of the root; passing through this muriatic acid gas, drying the precipitated muriate which is insoluble in ether, dissolving it in hot water, filtering, precipi- tating by ammonia, drying the precipitate, dissolving it in ether, decolor- izing by animal charcoal, again precipitating by means of muriatic acid gas, and decomposing the muriate as before. History.—Pure sanguinarina is a white, pearly substance, of an acrid taste, sparingly soluble in water, soluble in ether, and very soluble in alcohol. Exposure to the air changes it to a light yellow color. It forms soluble salts with the acids, which have some shade of red or scarlet, and are acrid and pungent to the taste. Its formula is NC37 Hi6 Os. Properties and Uses.—Same as the bloodroot. One grain of this alka- loid may be thoroughly triturated with tAventy or thirty grains of sugar of milk, and divided into ten or thirty doses, according to the effect desired. However, it is not much used in practice, the Sanguinarin being preferred. SANGUINARIN. Sanguinarin. THE ALKA-RESINOID PRINCIPLE OF BLOODROOT. Preparation. — Take of coarsely pulverized bloodroot, any quan- tity, alcohol a sufficient quantity to make a saturated tincture. When made, filter the tincture and add distilled water equal in quantity to that of the alcohol; distil off the alcohol, and allow the residue to rest for several days, or until precipitation ceases. Remove the supernatant liquid, wash the precipitate in a fresh supply of dis- tilled water, dry it carefully by a moderate heat, and pulverize for 846 Materia Medica. use. As thus prepared it consists of a portion of the alkaloid Sanguin- arina in combination with the Sanguinarin, and which is generally sold and used under the name of Sanguinarin. History.—As thus prepared, sanguinarin is of a deep reddish-brown color, a peculiar odor, of a bitterish, rather nauseous taste, followed by a sense of pungency in the fauces, which is persistent, soluble in boiling alcohol, insoluble in water, and does not coalesce, unless it is heated or exposed to moisture. It is fusible, forming a black shining mass, and is also inflammable. It is partially soluble in alkaline solutions, acetic acid, and ether. Properties and Uses.—This article is prepared by W. S. Merrell, and is an elegant and valuable, as well as important Eclectic agent. It possesses properties similar to bloodroot, and acts as a tonic, hepatic, and alterative. One or two grains, repeated every two hours, diminishes the velocity of the pulse in from eight to twelve hours; after which it only requires a small dose two or three times a day, to maintain its influence; and in effecting this sedative action on the arterial system, it does not produce any unfavorable cerebral results. It may be employed with advantage in the treatment of pulmonary diseases, influenza, hooping- cough, rheumatism, jaundice, etc. In combination with leptandrin and podophyllin it forms a medicine, which for safety and efficacy in the treatment of hepatic diseases is superior to any other remedies yet known in medicine; the combination may be formed into pills with extract of rhubarb, hydro-alcoholic extract of cimicifuga, or of bitter root. Com- bined with equal parts of caulophyllin, and hydro-alcoholic extract of cimicifuga, it will be found very efficacious in amenorrhea, dysmenorrhea, and other functional disorders of the female generative system. It may also be used as a sternutatory, and as a local application to indolent ulcers. When used alone it should be triturated with sugar, sugar of milk, or some other article. As a tonic, the dose is from one-fourth of a grain to a grain, three or four times a day; as a hepatic and alterative, from one-half of a grain to two grains. SANGUIS DRACONIS. Dragon's Blood. RESIN OF CALAMUS DRACO. Description.—Calamus Draco is a small palm growing in the Molucca Islands, and other parts of the East Indies. While the plants are young, the trunk is erect, and resembles an elegant, slender palm tree, armed with innumerable dark-colored, flattened elastic spines, often disposed in ob- lique rows, with their bases united. By age they become scandent, and overrun trees to a great extent. The leaves are pinnate, their sheaths and petioles armed as above described. The leaflets are single, alternate, Sanguis Draconis. 847 ensiform, margins remotely armed with stiff, slender bristles, as are also the ribs ; from twelve to eighteen inches long and about three-fourths of an inch broad. Spadix of the female hermaphrodite inserted by means of a short, armed petiole on the mouth of the sheath opposite to the leaf, oblong, decompound, resembling a common oblong panicle. Spathes several, one to each of the four or five primary ramifications of the spadix, lanceolate, leathery; all smooth except the exterior or lower one which is armed on the outside. Calyx turbinate, ribbed, mouth three-toothed, by the swelling of the ovary split into three por- tions, and in this manner adhering, together with the corolla, to the ripe berries. Corolla three-cleft; divisions ovate-lanceolate, twice as long as the calyx, permanent. Filaments six, very broad, and inserted into the base of the corolla. Anthers filiform, and seemingly abortive. Ovary oval; style short; stigma three-cleft; divisions revolute, glandu- lar on the inside. Berry round, pointed, of the size of a cherry. History.—On the surface of the ripe fruit, an exudation forms, which is removed by rubbing, or shaking in a bag, or by exposure to the vapor of boiling water, or, finally, by decoction. The first two modes procure the finest resin, which comes in small oval masses, from a half inch to two inches in diameter, covered with the leaves of the plant, and arranged together in a row like beads when strung; sometimes it is found in cylin- drical sticks, about a foot and a half in length, and from two to six lines in diameter, thickly covered with palm leaves, and bound round with slender strips of cane. In these forms it is opake, pulverizable, and dark- reddish-brown, yielding a fine scarlet powder. It also comes in tears or small irregular fragments, in the form of a reddish powder. WThen the fruit is boiled in water, it yields an inferior resin, which is in flat circular cakes about an inch thick, and two or three inches in diameter, and which affords a fine red powder. That in large disks, six to twelve inches in diameter by an inch thick, is a very inferior article, and is usually mixed Avith pieces of the shell, stem, and other impurities. Dragon's Blood is hard, opake, brittle, with a smooth, shining fracture, of a deep red color, inodorous, tasteless, insoluble in water, but soluble in alcohol, ether, and the fixed or volatile oils. It is composed of 90.7 parts of a red resin, called Draconin, 2.0 of fixed oil, 3.0 of benzoic acid, 1.6 of oxalate of lime, and 3.7 of phosphate of lime. Properties and Uses.—Dragon's Blood was formerly considered an astringent, and used in doses of from ten to thirty grains in passive hemorrhages, diarrhea, etc. It is sometimes used to impart color to plasters, in dentifrice preparations, and as an ingredient of paints and varnishes. It is an ingredient of the following preparation, which, whether deservedly or not, has acquired much reputation in the treat- ment of syphilis: Take of Dragon's Blood and Colocynth, of each, two drachms, Gamboge half an ounce, Sweet Spirits of Nitre and Balsam 848 Materia Medica. Copaiba, of each, two ounces. Mix the first three articles in a mortar, and then add to them three gills of boiling water; keep it hot, and stir for one hour, then cool, and after uniting the last two, add them to the first mixture, stirring for some time. The dose is a half ounce to pro- duce free catharsis; after which, a drachm, two or three times a day, to keep up a gentle action on the bowels. Notwithstanding the character of this compound, it is said to have effected cures in very severe forms of the disease. SANICULA MARILANDICA. Sanicle. Nat. Ord.—Apiaceae. Sex. Syst.—Pentandria Digynia. THE ROOT. Description.—This is an indigenous, umbelliferous, perennial herb, sometimes known by the name of Blacksnake Root, with a stem from one to three feet high, smooth, furrowed, and dichotomously branched. The leaves are from three to five-parted, digitate, mostly radical, on petioles from six to twelve inches long; segments from two to four inches long, half as wide, oblong, irregularly and mucronately toothed. Cauline leaves few, nearly sessile. The flowers are mostly barren, Avhite, some- times yellowish; the sterile flowers on slender pedicels; the fertile ones sessile. Segments of the calyx, entire. Involucres six-leaved, serrate. Umbels often proliferous; umbellets capitate. Fruits several in each urn- bellet, and densely clothed with hooked bristles. History.—Sanicle is common to the United States and Canada, and is found in low woods and thickets flowering in June. The root is the part used; it is fibrous, and has an aromatic smell and taste. Water or alcohol extracts its properties. Properties and Uses.—Sanicle is nervine, tonic, astringent, and slightly anodyne; it is very analogous to valerian, and may be substituted for it. It has been used with advantage as a domestic remedy in intermit- tent fever, sore-throat, croup, hives, and other cutaneous diseases. It is very efficacious in chorea, in doses of half a drachm of the powdered root, three times a day, to children eight or ten years of age. It has also been beneficially employed in various other nervous affections. The decoction of it is said to be valuable in gonorrhea, dysentery, passive hemorrhages, and leucorrhea, administered in doses of from two to four fluidounces, and repeated three or four times a day. The decoction used freely, at the same time bathing the wound with it, is reputed a certain cure for the bites of poisonous snakes. Sapo. 849 SAPO. Soap. Soaps embrace all those compounds which result from the reaction of salifiable bases with oils and fats. Oils and fats consist of two solid principles, and one liquid. Of the former, one is called Stearin, and is the chief ingredient of solid fats, as suet and tallow, the other is called Margarin, being the principal ingredient of soft fats, as lard ; and the liquid Olein characterizes the fluid fats or oils. Stearin is considered to be a combination of stearic acid and glycerin, or an acid stearate of the oxide of glycerile ; stearic acid is a firm, white solid, fusible at 167°, forming brilliant white needles on cooling, greasy to the touch, pulve- rizable, soluble in alcohol, very soluble in ether, but insoluble in water. It burns like Avax, and is used in the formation of improved candles. Margarin is viewed as a combination of margaric acid and glycerin, or a margarate of glycerin ; margaric acid is a white solid fat, of distinct acid properties, fusible at 140°, very soluble in hot alcohol, and in ether, and combines instantly with alkaline bases. Olein is a combination of oleic acid and glycerin, or an oleate of oxide of glycerile ; oleic acid, is a colorless oily fluid at temperatures above 57°, but when once melted, it does not solidify until cooled to 40°, and when soluble it does not melt until heated to 57°, and crystallizes in needles a little below 32°. It rapidly absorbs oxygen from the air, and becomes brown, is insoluble in water, soluble in alcohol and ether, lighter than water, and has a slight smell and a pungent taste. It forms salts with bases. The theory of saponification is, that these fatty acids unite with the alkaline base and form soaps, which are stearates, margarates, or oleates, as the case may be, of the particular base which has been added, while at the same time a non-saponifiable, sweet principle is set free, called glycerin,—which see under its proper head " Glycerina." When these fatly acids com- bine Avith soda, potassa, or ammonia, they form soluble soaps ; when united with earths and metallic oxides, as in the case of lead-plaster, lime-liniment, etc., the soaps formed are insoluble. Among the soluble soaps, those are the hardest which contain the most stearate, and those the softest which have a predominance of oleate, while an excess of margarate ranks in solidity between the two ; again, those soaps formed with soda are the hardest and least soluble, while the reverse is the case with those formed with potassa. Consequently, the hardest and least soluble soap is a stearate of soda, while the softest and most soluble, is an oleate of potassa. The theory of soap-making is very simple, depending on the affinity between the alkalies and the fat acids ; on the solubility in water of the alkaline stearates, margarates, oleates, etc.; and, finally, on the power of a certain amount of free alkali or sea-salt, to coagulate the soap, and render it insoluble in the liquid in which it swims, and which in fact 54 850 Materia Medica. runs off its surface as water does off the surface of fat, while yet the soap retains perfectly its solubility in pure water. Preparation.—The fat or oil is boiled with a solution of caustic alkali, by which it becomes gradually dissolved in the water, if there be not too great an excess of alkali present, until a ropy or gelatinous solution is formed, capable of being drawn out into long clear threads. After the soap is fully made, it is then to be separated from the remaining excess of alkali, glycerin, and water. This may be accomplished by boiling the solution down, until a strong alkaline solution is obtained, in which the soap is insoluble, and it then rises to the surface in a soft, half-melted state. As soon as it ceases to froth in boiling it is ladled out into molds or frames, and on cooling forms soap, which is cut into bars by means of a wire. Another method of causing the soap to separate from the water in which it is dissolved, is to add a very strong alkaline ley, in which the soap is insoluble, or common salt Avhich at once coagulates the soap, converting it into a soap of soda, if it be a soap of potassa. In either case the glycerin is carried off in the mother liquid. As first separated, the soap is called Grain soap, which may be purified by dis- solving it in an alkaline ley, and separating it by common salt. During this process the impurities subside, the soap combines Avith more water, and becomes weaker, but purer and whiter. If grain soap be not puri- fied it forms marbled soap, the marbled appearance being produced by adding to the soap as soon as it is completely separated, a fresh portion of ley, and immediately afterward a solution of sulphate of iron. The black oxide of iron is precipitated, giving rise to dark-colored streaks, which, by exposure to the air, become red, in consequence of the conver- sion of the black into the sesquioxide of iron. History. — There are three varieties of soap, which are officinal, namely, Spanish or Castile soap, Sapo Durus, which is made with soda and olive oil. Common soap, Sapo Vulgaris, made with soda and a concrete animal oil; it is white, and usually formed from barilla and tallow, and is used as the only proper soap for making opodeldoc. Also Soft soap, Sapo Mollis, made with olive oil and potassa. It is likewise made Avith other oils, as oil from various seeds, fish oil, and much of it in our own country is made with refuse fat and grease, and a ley of wood ashes. It is a potassa soap, completely dissolved in an alkaline solution in excess. White Castile soap is a mixed margarate and oleate of soda; common soap is a stearate of soda, and soft soap is a mixed margarate and oleate of potassa. Beside these, there are other varieties used more or less for medicinal or economical purposes, as follows : Sapo Amygdalinus, or Amygdaline soap, made by adding to oil of almonds twenty-one ounces, in small proportions and stirring frequently, a solution of caustic soda, (at 1.334 sp. gr.) ten ounces; leave the mixture for some days at a temperature of 64° to 68° F., stirring Sapo. 851 occasionally; then put into molds, until sufficiently solid. It should be exposed to the air for two months, before being used. Sapo Animalis, or Beef's marrow soap, made by boiling beef-marrow with two parts of water, and half a part of soda ley; when saponified, add one-fifth of common salt, stir, remove the soap from the surface, and place it in molds. Sapo Terebinthinae, or Starkey's soap, made by triturating together equal parts of subcarbonate of potassa, oil of turpentine, and Venice turpentine, until they combine. Sapo Windsor, or Windsor soap, a scented soda soap, made of one part of olive oil, and nine parts of tallow. Likewise Palm soap, made of palm oil and soda, and to which tallow is added to increase its firmness. Transparent soap, pre- pared by saponifying kidney fat with soda free from foreign salts, drying the resulting soap, dissolving it in alcohol, filtering and evaporating the solution, and running it into molds when sufficiently concentrated. It is yellow or yellowish-brown, and preserves its transparency after drying. Common Yellow or Rosin soap derives its peculiarities from an admixture of rosin, and a little palm oil with the tallow employed, the oil being added to improve its color. The several varieties of soap have the same general properties, as— a peculiar smell, a slightly alkaline taste, and being more readily soluble in hot than cold water, or alcohol. With alcohol it forms the Tincture of soap, which is a convenient test for discovering lime in natural waters. Soap is heaAder than water, melts, swells up and is decomposed by heat, and renders grease soluble in water. Acids give a milky appearance to an aqueous solution of soap, in consequence of setting free the oily acids, which become diffused through the water. Soap is adulterated by lime, gypsum, gelatin, etc., which may be knoAvn by its imperfect solubility in alcohol. Good white Castile Soap, is white, inodorous, entirely soluble in alcohol or water, is incapable of imparting an oily stain to paper, should not feel greasy, nor groAv moist, but should become dry Avhen exposed to the air, without exhibiting any saline efflorescence. Marbled castile soap is not so pure as the above. Soap is incompatible with all acids, which decompose it by uniting with its alkali, and setting free its fatty acids; also with earths and earthy and metallic salts, Avhich form an insoluble soap with their base, and a saline combination between their acid and the alkali of the soap. It may be used in hard water, when this has had all its lime precipitated, by the addition of sufficient carbonate of soda or carbonate of potassa, in the form of carbonate of lime. Properties and Uses.—Soap is antacid, antilithic, and in some measure laxative; it is usually given in combination with rhubarb in dyspepsia, torpor of the liver, and constipation. It has a tendency to correct the astringency of the rhubarb; and when combined with aloes, gamboge, or other resinous cathartics, it modifies in a greater or less degree their irritating properties. Being easily decomposed by the weakest acids, 852 Materia Medica. which unite with its alkali, it has proved beneficial in acid stomach, and as a remedy in the uric acid diathesis, but it does not dissolve calculi. It has also been recommended in solution as a remedy for poisoning with the concentrated acids, in which case it should be administered without delay every two or three minutes, until chalk, lime, or the bicarbonates of potassa or soda can be had. Externally, it is a stimu- lating discutient, and has been used by friction, or in the form of plaster, in sprains, bruises, and various tumors. A strong solution of soft soap forms a valuable enema in constipation, especially when arising from hardened feces in the rectum. In the preparation of pills, liniments, or plasters, care must be taken not to associate soap with a substance which may be decomposed by it. The dose of soap, is from five grains to half a drachm, in the form of pill. Off. Prep, of Common Soap.—Linimentum Cajuputi Compositum ; Linimentum Opii; Linimentum Saponis Camphoratum. Off.

Soapwort. Nat. Ord.—Caryophyllaceae. Sex. Syst.—Decandria Digynia. THE ROOT AND LEAVES. Description.—This is a stout perennial herbaceous plant, sometimes known by the name of Bouncing Bet, with a stem from one to two feet in hight. The leaves are lanceolate, inclining to elliptical, very acute, smooth, two or three inches long, and about one-third as wide. The flowers are many, large, flesh-colored or pale pink, often double and disposed in paniculate fascicles. The calyx is cylindrical, and slightly downy. Petals five, unguiculate ; crowns of the petals linear. Stamens ten ; styles two ; capsule oblong, one-celled. History.—Soapwort is found growing in Europe and the United States, by roadsides and in waste places, flowering in July and August. The root and leaves are the parts employed ; they are inodorous, of a bitter- ish and somewhat sweetish taste, succeeded by a persistent pungency, and imparting a slight sense of numbness to the tongue. When agitated with water they form a lather like soap-suds, which property together with its medical virtues, depend upon a peculiar principle termed saponin, which constitutes about thirty-four per cent., of the dried root, the remainder being gum, bassorin, resin, extractive, lignin and water. Water or alcohol extracts the properties of the root and leaves. Sapo- nin is obtained, though not absolutely pure, by treating the watery Sarracenia Purpurea. 853 extract with alcohol, and evaporating; it is brown, somewhat translu- cent, or, white and amorphous, hard, brittle, with a sweetish taste at first, then styptic, and finally, followed by a sense of acrimony in the fauces. It is soluble in water and officinal alcohol, but not in anhydrous alcohol, ether, or the volatile oils, When acted upon by alkalies, it is converted into saponic acid, C26 IL3 O12. Its aqueous solution froths when agitated, like a solution of soap. Properties and Uses. — Soapwort is tonic, diaphoretic, and alterative; and forms a valuable remedy in the treatment of syphilitic, scrofulous and cutaneous diseases, also in jaundice, liver-affections, rheumatism and gonorrhea. It is generally used in decoction ; although an extract, or the inspissated juice will be found equally efficacious. Dose of the decoction, from two to four fluidounces, three or four times a day ; of the extract, or inspissated juice, from ten to twenty grains. Saponin, may be used as a substitute for the root, and will likewise be found a powerful sternutatory. Dose, from two to six grains. SARRACENIA PURPUREA. Sarracenia. Nat. Ord.—Sarraceniaceae. Sex. Syst.—Polyandria Monogynia. THE ROOT. Description.—This plant, also known as Side-saddle Flower, Fly-trap, and Huntsman's Cup, is an indigenous, perennial plant, of a very curious character. The leaves or ascidia are from six to nine inches long, radi- cal, short-globose, inflated or cup-form, contracted at the mouth, having a broad arched lateral wing from half an inch to an inch in width, and extended on the outside of the mouth into a broad-cordate, erect lamina, or hood, covered above with reversed hairs. The scape is from one to two feet in hight, terete, smooth, and supporting a single, large, purple, nodding flower. History.—This plant owes its strange appearance to a curious pitcher- shaped metamorphosis of the leaf, which resembles very much an old- fashioned side-saddle ; six of these generally belong to each plant. The leaf, which springs from the root, is formed by a large hollow tube swell- ing out in the middle, curved and diminishing downward till it ends in a stem, contracted at the mouth, and furnished with a large spreading, heart-shaped appendage at the top, which is hairy within, the hairs pointing downward, so as to cause everything which falls upon the leaf, to be carried toward the petiole ; a broad wavy wing extends the whole length on the inside; these lie upon the ground with their mouths turned upward, so as to catch the water when it falls. They hold nearly a wineglassful, and are generally filled with water and aquatic insects, which undergo decomposition or a sort of digestion, and serve as nutri- 854 Materia Medica. ment to the plant. The stem rises direct from the root, it is round, quite smooth, and bears an elegant, deeply reddish-purple terminal flower, having two flower-cups; the external consisting of three small leaves ; the internal of five egg-shaped, obtuse leaves, shiny, and of a brownish-purple. The blossoms are five, guitar-shaped, obtuse, repeat- edly curved inward and outward, and finally inflected over the stigma, which is broad and spreading, divided at its margin into five bifid lobes, alternating with the petals, and supported on a short cylindrical style; this is surmounted by the stamens, which are numerous, having short threads, and large two-celled, oblong, yellow anthers attached to them on the under surface. In the yellow-flowered species of the Southern States, the bottle is very long, resembling a trumpet, by which name it is often called. The whole species are water plants, and are found only in wet mea- dows, wet boggy places, marshes, mud-lakes, etc., and are found from Labrador to Florida, flowering in June. There are several varieties, as the S. Heterophylla, found in the swamps at Northampton, Mass., and the S. Rubra, S. Flava, S. Variolaris, S. Drummondii, and S. Psytta- cina, which are common to the South, and all of which, probably, pos- sess similar medical virtues. The root is the part used, it has a bitter and astringent taste, and yields its properties to water. It contains coloring matter, resin, an acid salt of lime, an unknown salt, and lignin. Properties and Uses. — The therapeutical actions of sarracenia, are not fully ascertained. It is supposed to be a stimulating tonic, diuretic, and laxative ; in connection with Osmunda Regalis and blue cohosh, it will form a valuable syrup for chlorosis, all uterine derangements, dys- pepsia, and other gastric difficulties. An infusion of the leaf has been found equally available with that of the root. The best mode of em- ploying it, is not well determined ; though the powder may be given in doses of from twenty to thirty grains three or four times a day ; and the infusion from one to three fluidounces. In relation to this plant, Dr. C. H. Cleaveland makes the following remarks : " During the year 1847, Dr. F. P. Porcher, of South Carolina, experi- mented with the root, or that portion of the stem which is below the surface of the ground; and he details the following results : He thinks the bitter, and astringent principles of the plant are imperfectly extracted by water, and that the decoction is even more destitute of these proper- ties, than the cold infusion. He made trial of the root, in a recent state, as well as of the dried root, on his own person, and he gives the follow- ing, as the result of one of his experiments : ' Dec. 4th. We again commenced experimenting with it. It had become dry, having been rolled into pills of three grains each. Of these we took sixty (180 grs.), between ten and twelve o'clock, p. m., upon a comparatively empty stomach, swallowing them, at intervals, six or eight at a time. Its diu- Sarracenia Purpurea. 855 retic action in this instance was frequently repeated—the secretion being increased in quantity, pure, limpid, and colorless, with scarcely any sediment after -everal hours' standing. " ' Its action on the stomach, resembled that following its first employ- ment, being attended with the same phenomena. A feeling of emptiness was produced in the course of an hour. After retiring to bed, the whole abdominal region was in a state of commotion — extending along the tract of the ascending and descending colon, all of which appeared to participate in a kind of rolling motion produced by it. To these, were added involuntary rumbling sounds, as if the entire alimentary tube was stimulated, and apparently forewarning a cathartic effect. We are led to believe, that its astringent property presented this result. There was, also, tenderness on pressure at the epigastrium. " ' The feeling of congestion about the head, with irregularity of the heart's action, which lasted several days, was again observed. Before morning, the pulse rose to 100 by the watch — resuming its usual fre- quency after a time. We were prevented by sleep, which was much disturbed, from ascertaining positively the co-existence of strange im- pressions on the sensorial functions. The general vigor of the digestive apparatus was increased. The appetite following the next day was unusually active—seeming to demand much more to satisfy its require- ments; but there was a sense of pain about the stomach, like that fol- lowing inflammation, or that felt in the muscular tissue after a limb has been overtasked.' "In the first experiment, in which Dr. Porcher took 140 grains of the fresh root, the symptoms produced were very similar to those detailed in the above quotation — pointing distinctly to the parts of the system influenced by the drug: namely, the gastric filaments of the ganglionic, or organic system of nerves. This produced an increased action of the circulatory system, and drove the blood to the head. It also increased the peristaltic motion of the entire alimentary canal, and promoted the renal, and other glandular secretions, without any appa- rent effect upon the nerves of animal life. "As the experiments of Dr. Porcher are directly corroborative of those made by the writer, and confirmatory of the utility of the plant in all cases where there is a sluggish or torpid condition of the stomach, the intestines, the liver, the kidneys, or the uterus, producing costive- ness, dyspepsia, amenorrhea, dysmenorrhea, and the various functional derangements whieh are so commonly to be met with, it must be evident, that this plant possesses valuable properties, which render it well worthy the attention of the enlightened practitioner. " The plant has not yet been much used. It would, therefore, appear improper to speak of the best mode of preparing it, or of the amount necessary to be given to produce the desired result. Probably, how- ever, it will seldom be found necessary to resort to the heroic doses 856 Materia Medica. taken by Dr. Porcher, or to expect from its use the immediate effects observed by him. In almost all cases, gastric debility, dyspepsia, sick- headache, etc., are accompanied with a constipated condition of the bowels; and it would seem desirable to prepare the article in such a way as not to extract the astringent principle, whatever that may be; and doubtless the infusion or the syrup is as good a preparation as any. In those cases, however, which sometimes occur, when there is chronic diarrhea, without much inflammation of the intestines, it is altogether probable, that a cold infusion would be preferable. " It is even possible, that a new salt, similar to morphia or quinia, might be extracted from the plant, and a new and valuable remedy be added to our Materia Medica." SATUREJA HORTENSIS. Summer Savory. Nat. Ord.—Lamiaceaa. Sex. Syst.—Didynamia Gymnospermia. THE LEAVES. Description.—Summer Savory is an annual plant, with a branching and bushy stem, about eighteen inches in hight, woody at base, fre- quently changing to purple. The leaves are numerous, small, linear- oblong, entire, acute at the end. The flowers are pink-colored, on axillary, cymose peduncles. The calyx is tubular, ribbed, and about as long as the corolla. The corolla is bilabiate, with nearly equal divisions; stamens diverging, scarcely exserted. History.—This well known plant is a native of the south of Europe, and is extensively cultivated in the gardens of this country and Europe for culinary purposes, flowering in July and August. The leaves are the parts employed. They have an aromatic odor and taste, analogous to those of thyme, and impart their properties to boiling water in infusion, but more freely to alcohol. Its virtues depend upon a volatile oil. Properties and Uses.—Summer Savory is stimulant, carminative, and emmenagogue. A warm infusion is beneficial in colds, menstrual sup- pression, and flatulent colic ; the cold infusion is a gentle stimulating tonic, during convalescence from fevers. The infusion may be used in doses of from two to four ounces, several times a day. The oil is some- times used as a local application to carious teeth for relieving toothache; and its tincture is a valuable carminative. The S. Montana, or Winter Savory, with mucronate leaves, somewhat one-sided peduncles, and acu- minate and mucronate segments of the calyx, possesses similar properties. SCILLA MARITIMA. 857 SCILLA MARITIMA. Squill. Nat. Ord.—Liliaceas. Sex. Syst.—Hexandria Monogynia. THE BULB. Description. — Squill is a perennial plant with a roundish-ovate bulb, very large, half above ground, with the integuments either pale-green or red, and giving off fibrous roots. The leaves proceeding from the bulb, are broad-lanceolate, channeled, spreading, recurved, shining, deep-green, and make their appearance long after the flowers. The scape is tAvo or three feet high, and terminated by a rather dense, long, ovate raceme. The flowers are about three-fourths of an inch in diame- ter, spreading, pale yellowish-green, with a green mark on the middle of each segment. Peduncles purplish ; bracts linear, twisted, deciduous. Filaments shorter than the segments of the perianth. History.—Squill is a native of almost every part of the Mediterranean coast, and is also met with in Portugal and France. It flowers in August and September. Steinheil has proposed to remove it into a new genus under the name of Squilla Marilima, as the structures of its nec- taries and seeds distinguish it from the genus Scilla. The only officinal part is the bulb. When recent it is pear-shaped, from three to six inches in its largest diameter, and consists of concentric scales, the outer ones of Avhich are thin and membranous, while the inner are whitish, thick, fleshy, and full of juice; they weigh on an average from one to four pounds, though they have attained a weight of ten pounds and a half. There are two varieties known as the Red and White Squill; the former being distinguished by its reddish-broAvn external coat, its light- pink epidermis, and yellowish-white parenchyma of the inner scales; the latter being white throughout. The medicinal properties are the same in each. In the recent state the bulb contains a viscid, very acrid juice, which will inflame and even excoriate the skin, and the acrimony of which is much diminished by drying. When intended for medical use, squill bulbs ought not to be kept entire, but should be stripped of their outer scales, cut transversely into thin slices, and dried carefully at a temperature about 100° F. When recent, these slices have a mucila- ginous, disagreeably bitter, and somewdiat acrid taste, with a feeble radish-like odor. As found in the shops of this country, dried squill is in irregular, oblong pieces, often more or less contorted, of a dull yelloAvish-white color, with a reddish or rosy tint, sometimes entirely white, translucent, brittle, and pulverizable Avhen perfectly dry, but generally flexible from the presence of moisture, for which they have a great affinity. Occa- sionally a parcel will be found consisting of vertical slices, some of which adhere together at their base. The odor is very feeble, and the taste 858 Materia Medica. bitter, nauseous, and acrid. Squill yields its properties to water, spirit, or diluted acids; but the best solvents are proof spirit or vinegar. It contains, according to analysis, Scillitin, gum, a trace of tannin, traces of citrate of lime and saccharine matter, lignin, and an acrid principle. When kept dry, squill retains its virtues for a long time, but exposed to moisture it speedily becomes moldy. Scillitin may be obtained pure by treating a decoction of squill with acetate of lead, in order to separate the viscid matter, then filter, add finely powdered purified animal charcoal and Avhen cold agitate briskly, and afterward allow it to rest. The charcoal, as it subsides, carries along the bitter and coloring principles. Decant the liquid, and dry the remaining solid matter, and treat it, when dried, with hot alcohol, Avhich becomes intensely bitter. Distil off the alcohol, and allow the milky liquid which is left to evaporate spontaneously. Scillitin thus procured is pure, solid, uncrystallized, easily decomposable by heat, almost caustic to the taste, not deliquescent, neuter, slightly soluble in water, to which it imparts excessive bitterness, very soluble in alcohol, dissolved by con- centrated sulphuric or nitric acid, but at the same time decomposed, and imparting to the first a purple color, instantly becoming black. By allowing the last alcoholic solution to evaporate spontaneously, scillitin has been obtained in long, flexible, needle-shaped crystals. A single grain has killed a dog. A crystalline principle has been discovered in squill by Landerer, Scillitina, which is bitter, but not acrid, insoluble in Avater or the volatile oils, sparingly soluble in alcohol, and capable of neutralizing acids. It is procured by exhausting the bruised fresh bulb with diluted sulphuric acid, concentrating the solution, neutralizing it with lime, drying the precipitate, exhausting it with alcohol, and evaporating the tincture, which on cooling, deposits the scillitina in prismatic crystals. The acrid and bitter principles of squill are supposed to be distinct. Properties and Uses.—Squill is irritant, emetic, cathartic, diuretic, and expectorant. In large doses it is a dangerous irritant poison, pro- ducing inflammation of the alimentary canal, and urinary organs, and proving fatal in the dose of only twenty-four grains of the poAvder. Some constitutions are so susceptible of its irritant action, that it cannot be safely used in any dose, unless combined with opium. It is seldom used as an emetic or cathartic, on account of its uncertainty in producing these effects. In small doses it causes nausea and depression of the pulse, and never stimulates the circulation. Its expectorant action is greatly increased by the addition of opium ; and its diuretic by the con- junction of digitalis, or some other vegetable or saline diuretic. It is used in dropsy, catarrh, pneumonia, asthma, and phthisis. It acts better in general than in local dropsies, and also in those of an asthenic charac- ter. As an expectorant it will be found useful both in cases of deficient and of abundant secretion from the bronchial mucous membrane. SCROPHULARIA NODOSA. 859 Troublesome vomiting or purging caused by squill is best corrected by opium. Where there is much inflammation or vascular excitement, it is contra-indicated. Dose of the powder, as a diuretic and expectorant; from one to three grains ; as an emetic, from six to twelve grains ; of the syrup, one or two fluidrachms. When given in substance, its best form is that of pill. Off. Prep.—Acetum Scillae; Syrupus Scillae. SCROPHULARIA NODOSA. FigAvort. Nat. Ord.—Scrophulariacea?. Sex. Syst.—Didynamia Angiospermia. THE LEAVES AND ROOT. Description.—Figwort has a perennial, whitish, tuberous, and knotty root, with a herbaceous, erect, quadrangular, smooth stem, from two to six feet in hight, with paniculate, opposite branches above. The leaves are opposite, petiolate, ovate, ovate-oblong, or the upper lanceolate, acute, sharply and unequally serrated, rounded, acutish, or broadly cordate at base, veined, of a deep green color, and from three to seven inches in length. The flowers are small, three or four lines long, ovoid, dark-purple, slightly drooping, and borne on axillary and terminal, forked, angular, glandular peduncles in oblong thyrsoid panicles. Calyx in five segments which are broadly ovate, obtuse, slightly margined ; corolla of a dull green, with a livid purple lip, subglobose ; limb con- tracted, sublabiate, having a green scale or sterile filament, adnate to the upper side. Stamens didynamous ; sterile anthers, broadly orbicular. Capsule ovate-oblong. History.—This plant is a native of Europe, and found growing in dif- ferent parts of the United States, in woods, hedges, damp copses, and banks, flowering from July to October. The S. Marilandica and S. Lanceolata, known by the names of Carpenter's Square, Healall, Square- stalk, etc., are mere varieties, possessing similar medicinal properties. The leaAres and root are the officinal parts, and yield their virtues to water or alcohol. The leaves have a rank, fetid odor, and a disagree- able, bitter taste; the root has also a nauseous odor, and a sweetish, subacrid taste. Much of the odor and taste are lost by drying. The aqueous infusion, Avhich is reddish, is blackened by the sulphate of the sesquioxide of iron. They contain a brown bitter resin, an extractive having the odor of benzoic acid, extractive, gum, starch, inulin, etc. Properties and Uses.—Figwort is alterative, diuretic, and anodyne; highly beneficial in hepatic diseases, scrofula, cutaneous diseases, dropsy, and as a general deobstruent to the glandular system when used in infu- sion or syrup. Externally, in the form of fomentation, or ointment, it is valuable in bruises, inflammation of the mammae, ringworm, piles, 860 Materia Medica. painful tumors, itch, and cutaneous eruptions of a vesicular character. The root, in decoction, and drank freely, is said to restore the lochial discharge when suppressed, and to relieve the pains attending difficult menstruation. This plant possesses valuable and active medicinal pro- perties. Dose of the infusion or syrup, from tAvo to four fluidounces. Off. Prep.—Decoctum Scrophulariae ; Syrupus Rumecis Compositus. SCUTELLARIA LATERIFLORA. Scullcap. Nat. Ord.—Lamiaceaa. Sex. Syst.—Didynamia Gymnospermia. THE WHOLE HERB. Description. — Scutellaria Lateriflora has a small, fibrous, yellow, perennial root, with an erect, very branching, diffuse, quadrangular, nearly glabrous stem, from one to three feet in hight ; the branches are opposite. The leaves are on petioles about an inch long, opposite, thin, entire, nearly membranous, subcordate on the stem, ovate on the branches, acuminate, or acute, coarsely serrate and slightly rugose. The flowers are small, of a pale blue color, and are disposed in long, lateral, axillary racemes, Avith ovate, acute, entire, subsessile, distichous bracts, each flower axillary to a bract, and pedunculated. The calyx has an entire margin, which after the corolla has fallen, is closed with a helmet-shaped lid. The tube of Ike corolla about a quarter of an inch long, the upper lip concave and entire, the lower three-lobed. Seed, four in the closed calyx, oval, verrucose. History.—Scullcap is an indigenous herb, growing in moist places, meadows, ditches, and by the sides of ponds, flowering in July and August. It is known by the names of Blue-Scullcap, Side-Flowering Scullcap, Mad-Dog-weed, and Hood- Wort. The whole plant is officinal; it should be gathered while in flower, dried in the shade, and kept in well-closed tin vessels. It is inodorous, but has a bitterish taste; alcohol or boiling water extracts its properties. Scullcap is said to contain an essential oil; a fixed oil, yellowish-green, and soluble in ether; a bitter principle soluble in water, alcohol, or ether; chloro- phylle ; a peculiar volatile matter; albumen; a sweet mucous substance; a peculiar astringent principle; lignin, chloride of soda and other salts. Properties and Uses.— Scullcap is tonic, nervine, and antispasmodic. This is one of those valuable agents which a certain class of physicians consider inert; yet it has proved especially useful in chorea, convulsions, tremors, intermittent fever, neuralgia and all nervous affections. In delirium tremens, an infusion drank freely will soon produce a calm sleep. In intermittents, it may be beneficially combined with bugle. Where teething has impaired the health of children, an infusion may be given with advantage. In all cases of nervous excitability, restlessness, Secale Cereale. 861 or wakefulness, attending acute or chronic diseases, or from other causes, it may be drank freely with every expectation of beneficial results. The warm infusion has a tendency to keep the skin moist ; the cold has a tonic influence, and either may be drank freely. When its soothing effects have ceased, it does not leave an excitable, irritable condition of the system, as is the case with some other nervines. Half an ounce of the dried leaves or herb, to a half pint of boiling Avater, will make a very strong infusion. Scullcap has been extolled as a remedy in hydropho- bia, but this is still a matter of uncertainty. The S. Hyssopifolia and S. Integrifolia possess similar properties. The Pharmaceutical Institute of the city of New York, profess to have prepared a concentrated preparation of Scullcap, in the form of a whitish powder, which they name Scutelline, and recommend as atonic, nervine, etc., highly useful in nervous diseases. Having never seen the article, and not having been able to learn its mode of preparation, which appears to be kept a secret, with many of their other preparations, I can only refer to it as an article said to have been prepared.

THE SEED OR GRAIN. ERGOT A. (Secale Cornutum.) Ergot. Spurred, or Smut Rye. THE DISEASED SEEDS OF SECALE CEREALE. Description.—Rye has a stem from four to six feet high, hairy beneath the spike, in a wild state seldom over a foot high. The leaves are lance- linear, rough-edged and rough above, glaucous; the lower ones, together with their sheaths, covered with a soft down. Rachis bearded on each side with white hairs. Glumes subulate, ciliated, scabrous, shorter than the florets, taken together with their awns. Outer paleae folded up, keeled, tri-nerved, with very long awns ; the two nerves and awns very rough. Stamens three. Ovary pyriform, pilose. Stigmas two. History.—Rye is now cultivated in all temperate latitudes ; though its native country is unknown. At present it is thought to be originally from the countries around Caucasus. Ground into fine flour, it is used as an article of diet in the form of bread or mush. Bread made from rye-flour is dark-colored, and less digestible than that from wheat. Rye in grain consists of water, flour, and envelope ; the flour consists of starch, gluten, albumen, uncrystallizable sugar, gum, vegetable fiber, etc. 862 Materia Medica. Rye is very subject to a disease, caused by the growth of a fungus on the grains, which is called Ergot, or Spurred Rye. In relation to this substance, much difference of opinion has existed, having been thought by some as the seed altered by disease ; by others as the result of exces- sive heat and moisture ; and again, as a morbid condition produced by an insect. The general view, at the present time, is, that it is caused by the growth of a fungus on the grain, and which opinion is strengthened by the microscopic observations of Mr. Quekett of London. He states that the beginning of the growth of ergot, is marked by the appearance of numerous minute filaments, which run over all parts of the young grain and its appendages, cementing anthers and stigmas together, and of a white coating upon the surface of the grain, from which a multi- tude of minute particles separate, and sink, when immersed in water. These particles are about the four-thousandth of an inch long, and are sporidia or the reproductive agents of a species of fungus, Avhich may be observed to sprout and propagate in various Avays, under favorable circumstances, and Avhich give rise to the filaments. These sporidia and filaments do not increase Avith the growth of the ergot; and when this has projected beyond the paleae and become visible, it has lost a portion of its white coating, and presents a dark violet color. The grain increases rapidly, and attains its size in a few days, Avhen it exhibits very few of the filaments or sporidia upon its surface. It is stated that this fungus exists independent of the perverted grain, and that the sporidia will, upon application to the seeds of other Graminaceae before germina- tion, give rise to ergotized fruit. Mr. Quekett believes that the germs of the fungus emit their filaments through the tissue of the ergot when young and tender, and that, as this increases, it is made up partly of the diseased structure of the grain, and partly of the fungous matter; he named the fungus Ergotcclia Abortifaciens. Ergot generally projects out of the glume beyond the ordinary outline of the spike, and sometimes wholly occupies the place of the seeds, and at others only two or three spurs will be found in a spike. When gathered before harvest it is said to be more energetic, and should not be collected until several days after its formation, as, according to M. Bonjean, it does not possess the poison- ous properties on the first day of its formation, which it exhibits on the sixth. Ergot is in grains of a somewhat cylindrical, or obscurely triangular form, slightly curved like a cock's spur, from a third of an inch to one inch and a half, or rarely two inches in length, from one to three lines in diameter, solid, brittle, marked with one or two longitudinal furrows, often irregularly cracked or fissured, obtuse at the extremities, and ter- minated at the apex by a pale-gray excrescence, which, however, is generally rubbed off in what is found in the shops ; externally, it is of a dingy purple hue, or violet-brown color, and often somewhat glaucous, and internally it is pale grayish-red, grayish-white, or violet-white. It Secale Cereale. 863 has, when pulverized, a peculiar, musty, unpleasant smell, and a sweet- ish, slightly bitter, obscurely acrid taste. It is lighter than water, some- what of the consistence of horn, and under the microscope its external surface presents more or less of the sporidia, while its internal structure is composed of minute roundish cells, many of which, contain particles of oil. Unless kept carefully excluded from the air, it softens and swells, and becomes infected with numerous brown insects, about the size of a pin's head, while at the same time it acquires a deep black color and heavier odor. Its powder quickly becomes damp, and full of animal- cules. It should always be used recently pulverized, or if kept in pow- der, it should be in well-closed and darkened vials, and with a few lumps of camphor added. It imparts its virtues to water or alcohol; long boiling renders it inert. The best ergot is dry, and easily broken, free from insects, burns with a clear flame, and is incapable of forming a dark-blue pulp Avhen its powder is triturated with iodine and water. Ergot has been analyzed by various chemists ; according to a recent investigation by M. Legrip, he found it to contain in 100 parts, 34.50 of a thick, fine yellow, very fluid, fixed oil ; 2.75 of starch ; 1.00 of albu- men ; 2.25 of inulin; 2.50 of gum; 1.25 of uncrystallizable sugar; 2.75 of a brown resin ; 3.50 of funoin ; 13.50 of vegeto-animal matter ; 0.75 of osmazome ; 0.50 of a fatty acid ; 24.50 of lignin ; 0.50 of color- ing principles ; an odorous principle not isolated ; 2.25 of fungate of potassa ; 0.50 of chloride of sodium ; 0.50 of sulphate of lime and mag- nesia ; 1.25 of subphosphate of lime ; 0.25 of oxide of iron ; 0.15 of silica; 2.50 of water, and 2.35 loss. H. L. Winckler gives as the most important chemical constituents, secaline in combination with ergotine, a red ferruginous coloring matter with a base yet to be eliminated, albu- men soluble in water and in a coagulated condition, a large quantity of fatty oil, which in the normal grain appears to be replaced by amylon, fungous sugar, which disposes the Avatery extract of ergot of rye so strongly to fermentation, formiates, and phosphates. He considers the specific action of ergot ascribable to the secaline compound, or the color- ing matter, or both of these compounds together and not to the fatty oil. A watery extract is, he states, the most active preparation, but it cannot be kept; a tincture, prepared with alcohol of 10 per cent., by several days' digestion at an ordinary temperature, from finely pulver- ized ergot, is of a dark-brown color, and contains all the active constitu- ents of the ergot, with very little fatty oil, which separates in a crystal- line form at very Ioav temperatures. The spirituous extract is best kept and most effective when it is prepared by twice extracting the fine pow- der with an equal quantity of cold distilled Avater, clarifying the concen- trated extract, and treating it with alcohol of 80 per cent, as long as a precipitate results on the addition of a fresh portion. The spirituous fluid is after tAventy-four hours separated from the precipitate by filtra- tion; the filtrate subjected to distillation in a water-bath, and the residue 864 Materia Medica. evaporated to the consistence of an extract. Obtained in this way, the extractive ergotine is a little hygroscopic, has a light-brown color, a slight narcotic odor, dissolves under the separation of a little ergotine ( Wiggers) in water, and evolves, when treated with a solution of caustic potassa, the penetrating odor of secaline in a high degree. By distilla- tion of the concentrated watery extract with caustic lime, a very concen- trated solution of secaline is also obtained. Winckler has found the compound of ergotine with secaline, ergotinate of secaline in the black sporous mass of Lycoperdon Cervinum. Wiggers digested ergot in ether, and aftenvard in alcohol, evaporated the alcoholic solution, and treated the extract thus obtained with water, which left a reddish-brown powder, undissolved. Supposing this to be the active principle of ergot, he named it Ergotin ; it possessed a pecu- liar nauseous odor, and a bitter, slightly acrid taste, and was soluble in alcohol, but insoluble in Avater or ether. Dr. Christison and Dr. Wright have not been able to obtain ergotin after the process of Wiggers. Winckler dried some recent ergot of rye at 139° F., pulverized it, and extracted first with ether, then with water. The aqueous solution Avas treated with strong alcohol, and separated from albuminous matter by filtration ; the spirit was distilled off, and the residue brought to dryness. During this operation a small quantity of a brown powder, (the Ergotine of Wiggers,) was precipitated, which again dissolved in the concentrated liquid. The residue above, (Winckler's Extractive Ergotine,) dissolved readily in alcohol and Avater under the precipitation of a light-brown powder, (the Ergotine of Wiggers). It had a bitterish, cooling taste, and, when distilled with quicklime, afforded a distillate with the odor of her- rings, containing propylamine or trimethylamine, but no ammonia. The residue consisted of a compound of secaline, (a volatile base,) with Wig- gers' ergotine, which Winckler regards as an acid. The solution with ether, first extracted, contained a fatty oil, equal to 3-1 per cent, of the ergot. By treating ergot with alcohol acidified with sulphuric acid, he extracted a red ferruginous coloring matter. The Oil of Ergot, introduced into practice by Dr. Wright, contains the active principle of ergot, and is very generally employed as a substitute for the crude article. It may be obtained by forming an ethereal tincture of ergot by the process of displacement, and evaporate by means of gen- tle heat. It is sometimes colorless, but generally reddish-broAvn, has a disagreeable, somewhat acrid taste, is lighter than water, and is soluble in alcohol, or alkaline solutions. Its effects are identical with those of ergot. When the oil is obtained by simple expression, it is destitute of the peculiar medicinal influences of that prepared by means of ether. Ergot is incompatible with acetate and subacetate of lead, nitrate of silver, and tincture of galls. Iodine does not indicate starch in it. Its aqueous infusion is claret-colored, and has an acid reaction. Secale Cereale. 865 Properties and Uses.—The free and long-continued use of ergot, gives rise to very terrible and dangerous symptoms, even when no immediate effects are perceptible, as dry gangrene, typhus fever, or convulsions. In doses of from thirty to sixty grains, it often occasions nausea, vomit- ing, and in still larger doses, it causes a sense of pain and weight in the head, giddiness, dilated pupils, delirium and stupor. It reduces the frequency of the pulse, even without nausea. Medicinally, ergot is used on account of its power of promoting uterine contraction in languid natural labors. When thus employed, it produces a strong and contin- uous contraction and rigidity, without any alternation of contraction and relaxation, as observed in the natural process of labor; conse- quently, unless the os uteri and external parts are sufficiently soft and yielding, the constant pressure exerted upon the child, causes injury to it, and very often death. Its use should always be avoided, if pos- sible, in first pregnancies. The conditions for safety and success are, that labor be somewhat advanced, the mouth of the womb moderately dilated, that no mechanical obstruction to delivery exists, from deformity of the pelvis, rigidity of the os uteri, mal-presentation, or disparity of the size of the child to the parts of the mother, and that the only cause of the slow progress of labor is insufficiency of the uterine contractions, in point of force or frequency. One or two drachms of the powder may be stirred in four fluidounces of hot water, and when sufficiently cool, may be given in tablespoonful doses every ten minutes, until labor-pains are induced; usually in fifteen or twenty minutes, the labor-pains increase in force and frequency, and gradually become continuous, and effect the expulsion of the child within an hour. Many objections are raised to its use, but, in general, if prudently administered, no bad effects will ensue. Dr. Catlett asserts that it will give rise to puerperal convulsions, hour- glass contraction of the uterus, and hydrocephalus in the new-born infant. It may also be given in cases where the fetus is dead, and cir- cumstances require speedy delivery, as great exhaustion, or dangerous constitutional irritation. It may likewise be administered to facilitate abortion when it has once commenced, as well as to check uterine hemorrhage in the gravid or non-gravid state; it has likewise proved serviceable in hemorrhages from other organs, as the lungs, stomach, etc. It may likewise be given with advantage in retained placenta, as well as promoting the expulsion of a mole, hydatids, a clot of blood, or other uterine contents, when the womb has once begun to act. It is doubted by many whether it will excite uterine contractions in any in- stance, unless a natural movement toward such action has commenced. In small doses, it has been recommended in painful dysmenorrhea, where membranous shreds pass off. It has also been recommended in leucor- rhea, gleet, gonorrhea, chronic diarrhea and dysentery, paraplegia, paralysis or debility of the bladder, and of the rectum, spermatorrhea, hysteria, and intermittent fever. In these affections it may be given in 55 866 Materia Medica. doses of from five to ten or fifteen grains three times a day; but its use should not be continued for a great length of time, on account of its ten- dency to cause dangerous symptoms. The Oil of Ergot may likewise be used as an aid to parturition, and in uterine affections, in the place of ergot; it is equally effectual in closes varying from tAventy to fifty drops, and which may be given in water, tea, or some aromatized syrup. In the dose of ten drops, it has been beneficially employed in diarrhea, and in gastric irritability and spasm; the dose may be repeated every three or four hours. Externally, the oil has been found serviceable as an anodyne in rheumatism, toothache, and as a styptic in hemorrhage from wounds ; in this latter instance care must be employed in its application, as ergot has produced sloughing, when applied to abraded surfaces on the lower animals. The oil will retain its properties for several years, if kept in well-closed bottles in a cool place, and excluded from light; an elevated temperature or a pro- longed exposure to the sun's rays diminishes its activity. Rye flour, in the form of mush, is an excellent laxative article of diet, and may be given with much benefit in hemorrhoids and prolapsus ani, with accompanying constipation, mixed with molasses. In the dry state, rye flour has been found an excellent application to erysipelatous inflam- mations, and some other eruptive affections, allaying the burning and itching, and absorbing the irritating secretions. In the form of poultice, it is often applied to discuss tumors or swellings, or to hasten their sup- puration Avhen far advanced. Green rye, Avhen from six to ten inches high, made into a salve by simmering in fresh cream, I haAre knoAyn to cure several most inveterate cases of tinea-capitis ; to be applied to the scalp, twice a day.

Description. — This plant is the Cnidium Palustre of Sprengel, the Peucedanum Montanum of Koch, and the Conioselinum of Fischer. It has a simple, tapering, perennial root, with many long fibers. The stem is erect, four or five feet high, hollow, deeply furrowed, not hairy, branched and corymbose in the upper part, bright-purple at the base. The leaves are about five or six on the stem, alternate, remote, ternate with bipinnate divisions; the leaflets are opposite, deeply pinnatifid, dark-green, smooth, their segments Hnear-lanceolate, never quite linear, acute, entire, or trifid; the petioles are smooth, striated, dilated, and sheathing at the base, with a reddish membranous margin. Umbels large, horizon- Selinum Palustre — Sempervivum Tectorum. 867 tal, of numerous, angular, general and partial rays. General bracts several, lanceolate, pointed, dependent, not half the length of the rays, their margins membranous and partly colored; partial ones similar, rather longer in proportion, and often confluent. Flowers Avhite, numer- ous, uniform, with involute petals. Fruit very light straw color, four lines long, shining, obovate; the dorsal ridges very near each other, dis- tinctly elevated, sharp, the lateral depressed and far within the broad thin margin; vittce of the commissure subulate, straight, about half the length of the fruit. History.—This plant grows in marshes and boggy meadows in the north and middle of Europe. The root abounds in a white fetid, bitter juice, which hardens into a brown acrid resin; it is the part employed. It imparts its properties to water or alcohol. Properties and Uses. — Marsh Smallage is emmenagogue, diuretic, and antispasmodic, but abandoned as an internal remedy, on account of its caustic and dangerously poisonous properties. Ten or twenty grains, according to the patient's age, repeated every five hours, and after a time gradually augmented, have cured several cases of epilepsy; but it must not be used where abdominal obstructions exist, or where there is an exalted sensibility of the genital apparatus. In nervous and sanguine persons, especially those of irritable habits, it increases the violence of the disease. Two grain doses, repeated twice daily, have proved almost immediately beneficial in the convulsions of children during the process of dentition. The Marsh or Hemlock Parsley, Selinum Canadense, or Cnidium Canadense of Sprengel, and Conioselinum Canadense of Fischer, which groAvs in swamps, wet Avoods, and around the mouth of large rivers from Canada to Carolina, and westward, is a species of the above plant, and deserves a trial in the diseases just mentioned. It is a plant from two to four feet in hight, somewhat resembling the Conium Maculatum, and having an angular, flexuous, hollow stem. The leaves are on large, inflated petioles, ternately divided; the divisions bipinnate, with linear-oblong, acute lobes. Umbels compound. Petals white, spreading. Involucre wanting, or two or three-leaved. Styles slender, diverging. Fruit about two lines long, oblong-oval. Vittce solitary in the dorsal intervals, tAvo or three in the lateral. It flowers in August and September. SEMPERVIVUM TECTORUM. Common Houseleek. Nat. Ord.—Crassulacefc. Sex. Syst.—Polyandria Polygynia. THE LEAVES. Description. — Houseleek has a fibrous root crowned with several rosaceous tufts of numerous, oblong, acute, keeled, fringed, extremely 868 Materia Medica. succulent leaves. The stem from the center of one of these tufts, is about a foot high, erect, round, downy, clothed Avith several, more narrow, sessile, alternate leaves, and terminating in a sort of many-flowered cyme, with spiked branches. Flowers large, pale rose-colored, without scent. Segments of the calyx twelve or more, with a similar number of petals, stamens, and pistils. Offsets spreading. History.—This is a well known perennial plant, a native of Europe, where it is found growing on rocks, old walls, and the roofs of houses, flowering in August, and is remarkable for its tenacity of life. It sends out runners with axillary offsets by which it is propagated, and rarely flowers. It is sometimes cultivated as an ornament, or as a domestic medicine. The recent leaves are the parts used, they are from half an inch to two inches in length, thick, fleshy, succulent, flat on one side, somewhat convex on the other, smooth, of a light green color, inodo- rous, and of a cooling, slightly saline, astringent, and sourish taste; they contain a large proportion of supermalate of lime. The juice of the leaves filtered with an equal quantity of alcohol, forms a beautiful, white, highly volatile coagulum. Properties and Uses.—The leaves of Houseleek are usually employed in the recent state, bruised, and applied as a cooling application to burns, stings of insects, ulcers, erysipelas, and other external inflammations. The leaf sliced in two, and the inner surface applied to warts or corns, and changed twice a day, will, it is said, positively cure them. The juice, applied locally, has cured ringworm, shingles, and many other cutaneous affections. Dr. A. Brown, of Cincinnati, recommends the following in many cases of deafness : fill a four or six ounce vial with the leaves of houseleek, cork it tightly, and place it within an unbaked loaf of bread. When the bread is baked remove the bottle, and there will be found a liquid of a soft, oily character, which may be dropped into the ear, say one or two drops, every night. When applied it pro- duces a singular, stimulating sensation. In erysipelas, he has found much benefit from the free interna] use of the leaves bruised in milk and water, in quantity sufficient merely to stain the liquid. The bruised leaves applied as a poultice, have, in his hands, cured severe cases of shingles in twenty-four hours. The leaves also possess an astringent property, which is beneficial in many cases. SENECIO AUREUS. Life Root. Nat. Ord. —Asteraceae; Tribe, Senecionideae. Sex. Syst.—Syngenesia Su- perflua. THE ROOT AND HERB. Description.—This plant is known by several other names, as Rag- wort, False Valerian, Golden Senecio, Squaw-weed, and Female Regulator. Senecio Aureus. 869 It has an erect, smoothish, striate stem, one or two feet high, floccose- woolly when young, simple or branched above, terminating in a kind of umbellate, simple, or compound corymb. The radical leaves are simple and rounded, the larger mostly cordate, crenate-serrate, and long- petioled; the lower cauline leaves lyre-shaped; the upper ones few, slender, cut-pinnatifid, dentate, sessile or partly clasping, the terminal segments lanceolate. Peduncles subumbellate and thick upward. Corymb umbel-like. Rays from eight to twelve, four or five lines long, spreading. Flowers golden-yellow. Scales linear, acute, and purplish at the apex. History. — This is an indigenous, perennial plant, growing on the banks of creeks and on low marshy grounds, throughout the northern and western part of the Union, flowering in May and June. The root and herb are the officinal parts, and the medicine is peculiar to Eclectics, not being known to other practitioners; it yields its properties to water or alcohol. It has not been analyzed. There are several varieties of this species, which possess similar medicinal virtues, as the Senecio Bal- samitos, or Balsam Groundsel, with the stem and peduncles villous at base ; the leaves few, small and distant, pubescent; the radical ones oblong, spatulate, or lanceolate, sometimes cut-toothed, tapering into the petiole ; cauline ones lyrate or pinnatifid ; flowers subumbellate. This variety grows in pastures and on rocky hills. Another, the Senecio Gracilis, Unkum, or Female Regulator, a slender state of the species, found on rocky shores; its radical leaves are orbic- ular, on long petioles, subcordate, crenate; cauline ones very few, remote, linear-oblong, dilated at the base, incisely dentate ; peduncles very short, pilose, subumbelled ; involucre smooth; rays few, very short. The Senecio Obovatus with the radical leaves obovate, crenate- serrate, petioled ; cauline ones pinnatifid, toothed ; flowers subumbelled long-peduncled, bracted, with a cavity under the receptacle like some other of the genus; stem somewhat glabrous. Found in meadows, etc. Senecio Lanceolatus, found in shady cedar swamps in Vermont; it has all the leaves lanceolate-oblong, thin, sharply and unequally toothed, either wedge-shaped or somewhat cordate at the base, the upper cauline ones being pinnatifid-cut toward the base. Among these varieties, the Senecio Gracilis is considered the most efficient in uterine difficulties, and it is from this that the Senecin is prepared. The whole herb is used. The root grows just below the surface of the ground, and runs along horizontally; it is from half an inch to six or eight inches in length, and about two lines in diameter, reddish or purplish externally, white-purplish internally, with an aromatic taste, and having scattered fibers. When dried, and mixed with the herb, it is found of various lengths from one-fourth of an inch to an inch or two, greenish-brown, or yellowish-brown externally, with very fine longitudinal 870 Materia Medica. lines, a few fibers attached, short fracture, presenting under the micro- scope a shining, waxy surface, with a central pale-purple substance surrounded by a greenish-yellow one, with a light-yellowish ring between the two; it is inodorous, and has a faintly bitter, herbaceous, peculiar, resinous taste, with a very slight degree of pungency. It yields its properties best to alcohol. Properties and Uses.—Life Root is diuretic, pectoral, diaphoretic, tonic, and exerts a peculiar influence upon the female reproductive organs, which has given to it, especially the S. Gracilis, the name of Female Regulator. It is very efficacious in promoting the menstrual flow ; and may be given alone, in infusion, or combined with equal parts of asarum and savin, in amenorrhea not connected with some structural lesion. It will also be found valuable in dysmenorrhea. In menorrhagia, com- bined with cinnamon and raspberry leaves, it has been found very ser- viceable, when administered during the intermenstrual period, as well as at the time of ovulation. It has proved an excellent diuretic in gravel and other urinary affections, either alone, or given in combination with other diuretics; and is said to be a specific in strangury. In pulmonary and hepatic affections it has proved advantageous; and taken freely, the decoction has effected cures of dysentery. This is one of our valuable agents in the treatment of female diseases. Dose of the decoction, four fluidounces, three or four times a day. Off. Prep.—Decoctum Senecii; Extractum Senecii Fluidum. Senecin. SENECIN. Senecin. THE CONCENTRATED ACTIVE PRINCIPLE OF SENECIO GRACILIS. Preparation.—Make a saturated tincture of the root and herb of Sen- ecio Gracilis, add to it an equal quantity of water, and distil off the alcohol; the senecin remains in the water, which must be removed by filtration. History.—Senecin thus prepared, is an oleo-resin of thick consistence, of a very dark-green color, appearing quite black in mass, having a peculiar, herbaceous odor, and a bitter, slightly pungent, persistent, and rather unpleasant taste. A portion of it, probably the oil, is soluble in alcohol, imparting a green color to the solution ; on the addition of liquor potassa to the alcohohc solution, the senecin is rendered wholly soluble, and if muriatic acid be added in small quantity, it changes the green solution to greenish-white, without precipitation. It is entirely soluble in sulphuric ether, forming a greenish solution, which is not precipitated by water, nor acetic acid. It is insoluble in water, but becomes soluble on the addition of strong alkaline solutions. Sesamum Indicum. 871 The Franklin Institute of the city of New York, publish a preparation as Senecin, the active principle of Senecio Gracilis; they state that it is a whitish-brown powder, agreeable to the stomach, and pleasant to the taste. I have never seen the article, nor do I know how it is prepared, but from a specimen of their Stillingin, I am inclined to view it as the oleo-resin triturated with sugar, or sugar of milk. And if such be the case, it shows the necessity that exists, for practitioners to employ no secret agents, nor such as are prepared by secret processes, lest they be imposed upon in the article itself, as well as in the exorbitant price demanded for it. Properties and Uses.—Senecin possesses the virtues of the plant from which it is obtained, in a high degree. It is, however, more especially employed in the treatment of female diseases, as amenorrhea, dys- menorrhea, and other uterine derangements. Combined with aletrin, caulophyllin, or cimicifugin it Avill be found especially useful in these complaints. In menorrhagia it may be combined with geraniin advan- tageously ; or its ethereal tincture may be administered in some astrin- gent infusion. A pill of senecin, aletrin, and sulphate of iron, will be found of benefit in chlorosis accompanied with amenorrhea. In dys- menorrhea it may be combined with extract of belladona and sulphate of quinia. It is one of those agents which exert a tonic influence upon the uterus, thereby restoring its various functional derangements to a normal condition. Dose of Senecin, from three to five grains, three times a day. SESAMUM INDICUM. Benne. Nat. Ord.—Pedaliacea?, Lindley; Bignoniae, Jussieu. Sex. Syst. — Didyna- mia Angiospermia. THE LEAVES AND SEEDS. Description. — Sesamum Indicum is an annual plant with an erect, pubescent, branching stem from two to four feet in hight. The leaves are ovate-lanceolate, or oblong ; the lower ones trilobed and sometimes ternate; the upper undiAdded, irregularly serrate and pointed. The flowers are of a reddish-white color, axillary, on short glandular pedicels. The fruit is an oblong, mucronate, pubescent capsule, containing numer- ous small, oval, yellowish seeds. History.—There are tAvo species of this genus, the S. Indicum, and the S. Orientale, both of which are natives of the East Indies, and are now extensively cultivated in many parts of Asia, Africa, West Indies, and in the Southern United States. That growing in the South is the S. Indicum, and flowers in August. Both the seeds and leaves are offi- cinal. The first are small, yellowish, or in some cases blackish, of a 872 Materia Medica. pleasant, mucilaginous taste, and yield by expression an excellent, bland, sweetish, inodorous, fixed oil, closely resembling olive oil, and which may be used as a substitute for it in all cases. Five pounds of the seeds afford about one pound of oil, which will keep several years with- out becoming rancid. The seeds are much employed by the negroes as an article of food; they parch them, and prepare them into puddings, broths, and various other ways. The leaves abound in a gummy matter, which they impart to water, forming a rich, bland mucilage. Properties and Uses.—One or two fresh leaves, stirred in about half a pint of cool water, forms a bland and demulcent drink, very useful in catarrh, diarrhea, dysentery, summer-complaint, and irritation of the urinary organs. When the leaves are dried, hot water should be used. This mucilage likewise forms an excellent soothing application in oph- thalmia, irritations and diseases of the skin, etc., but is not at all supe- rior to that of slippery elm, or of sassafras pith. The oil may be used as an application to furfuraceous eruptions—or, in large doses, as a laxa- tive. In India it is considered to possess emmenagogue properties, and capable of producing abortion. SEVUM. Suet. THE PREPARED FAT OF OVIS ARIES. History.—Suet, Mutton Suet or Sheep Tallow, is the fat of the domestic sheep, ovis aries. For medical purposes it is usually obtained from the fat around the kidneys, cut into pieces, melted with a moderate heat, and strained through linen or flannel. It is sometimes purified by boiling it in a little water, thus avoiding too great a heat. It is some- what similar in its properties to lard, but is of a firmer consistence, and requires a higher temperature (103°) for its fusion than any other animal fat. When fresh and well prepared, it is white, inodorous, of a bland taste, sometimes brittle, insoluble in water, and nearly so in alco- hol; when long kept it is apt to become yellow, rancid, and consequently unfit for pharmaceutic purposes. According to Chevreul, it consists of stearin, olein, and a small proportion of hircin; and its ultimate composition is Carbon 78.99, Hydrogen 11.70, Oxygen 9.30. Hircin is a liquid-like olein, but is more soluble in alcohol; by saponification it is convertible into hirsic acid and glycerin, and is therefore a hircate of oxide of glyceryle. Mr. Wiggin, of Ipswich, has patented a mode for melting and puri- fying tallow and other kinds of grease. The process consists in heating the fatty substance in the state in which it is removed from the animal, with a small quantity of sulphuric acid of specific gravity 1.3 to 1.45. The acid dissolves the membrane and other impurities present, acquir- SlLPHIUM PERFOLIATUM. 873 ing a dark color and thick syrupy consistence, while the fat separates in a state of great purity. It has been suggested that the fats obtained by this process were probably the fatty acids resulting from the decom- position of the neutral fats by the oil of vitriol; but Mr. Wiggin replies that in using the sulphuric acid at the density indicated, no decomposi- tion of the fats was effected, and that no sulphurous acid was evolved in the process. Properties and Uses.—Suet is nutritive and emollient, but not so easy of digestion as the fat of the pig or ox; yet made into a broth, with or without aromatics, and used in diarrhea, dysentery, and general debility. It is sometimes used as a dressing to blisters, and may be applied to most of the purposes for which lard is used, on account of its superior hardness, and higher melting point. For forming an ointment, it will be found preferable to lard, especially when it is to be applied to several forms of cutaneous disease. SlLPHIUM PERFOLIATUM. Indian Cup-plant. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Necessaria. THE ROOT. Description.—This plant, also known by the name of Ragged Cup, has a perennial, horizontal, pitted rhizome, beset with radicles, and a large, smooth, square herbaceous stem, from four to seven feet high, and often branched above. The leaves are opposite, connate-perfoliate, ovate, coarsely toothed, abruptly narrowed into winged petioles at the base, the upper pairs forming a cup-shaped disk with their connate bases ; they are from eight to fourteen inches long, by four to seven wide. The flowers are terminal, with from fifteen to twenty-five oblong, lanceolate, yellow rays, and a large dark colored disk. Heads in a trichotomous cyme, the central on a long peduncle ; scales ovate, obtuse, squarrose; achenia broadly ovate, winged, emarginate. History.—This plant is common to the Western States, and is found growing in rich bottom or interval lands, bearing numerous yelloAv flowers in August. The root is the officinal part; it is large, long and crooked, and imparts its properties to water or alcohol. It has a persistent, acrid taste. There are several species of Silphium, which yield by exuda- tion and incision a fine fragrant and bitterish gum like Frankincense, white or amber color, and which is chewed by the Indians to sweeten the breath. Properties and Uses.—Cup-plant is tonic, diaphoretic, and alterative. A strong infusion of the root, made by long steeping, or an extract, is said to be one of the best remedies for the removal of aguecake, or enlarged spleen; it is also useful in intermittent and remittent fevers, 874 Materia Medica. inward bruises, debility, ulcers, liver affections, and as a general altera- tive restorative. The gum is said to be stimulant and antispasmodic. The S. Gummiferum, or Rosin-weed, and S. Laciniatum, or Compass- weed, are said to be emetic in decoction. They have effected cures in intermittent fever, and are beneficial in dry, obstinate coughs. Said to cure the heaves in horses. The dose of the powdered root of S. Per- foliatum is twenty grains. SIMARUBA OFFICINALIS. Simaruba. Nat. Ord. — Simarubaceas. Sex. Syst. — Decandria Monogynia. THE BARK OF THE ROOT. Description.—Simaruba, called in Jamaica Mountain Damson, is a tree with long, horizontal, creeping roots, and a trunk about sixty feet in hight, covered with a blackish, furrowed bark, and sending off alternate spreading branches, Avhose bark is smooth, gray, and marked with broad yellow spots. The wood is hard, white, and has scarcely any bitter taste. The leaves are alternate and abruptly pinnate, with a long, naked petiole, sometimes nearly fourteen inches long, to which the leaflets are attached by short footstalks. The leaflets are alternate, from two to nine on each side, about two inches long, obovate, entire, someAvhat coria- ceous, smooth, dark-green above, and whitish beneath. The flowers are of a yellowish-white color, and are disposed in long axillary panicles; some describe them as' monoecious, others as dicecious ; which last is said to be the case with the tree in Jamaica. The calyx is small, and divided into five obtuse, erect segments. The petals are stiff, lan- ceolate, equal, spreading, somewhat reflexed, and much longer than the calyx. The stamens are ten, equal, about as long as the corolla, bearing oblong, incumbent anthers, with a small hairy scale at the base. The ovary is ovate, five-parted, crowned with an erect, cylindrical style, bearing a five-lobed stigma, and surrounded at base with a ring of hairy scales. The fruit consists of five ovate, black, smooth, one-celled ber- ries, all connected with a fleshy, pentagonal receptacle, and opening by a fissure when ripe, each containing a single, oblong seed. History.—Simaruba is found in Jamaica, Guiana, and several parts of South America. Although placed in the class and order Decandria Mono- gynia of the Sexual System, it evidently is pentagynous; for although the styles are connected above, yet they are distinct below, are crowned with five connected stigmas, and spring from a five-lobed ovary. It prefers a sandy, arid soil, and flowers in NoArember and December. The bark of the root is the officinal part. The root is rough, scaly, and warty, and its bark is intensely bitter. When dried, as met with in commerce, it is in pieces several feet in length, and some inches in breadth, folded lengthwise, light, flexible, tenacious, very fibrous, exter- Sinapis Alba — Sinapis Nigra. 875 nally of a light brownish-yellow color, rough, warty, and marked with transverse ridges, and internally pale-yellow. It is inodorous, of a purely bitter taste, not easily pulverizable, and imparts its bitterness to water or alcohol. It is said to contain a bitter principle identical with quassin, resin, a volatile oil with the odor of benzoic acid, malic acid, traces of gallic acid, oxide of iron, silica, and several other unimpor- tant ingredients. Properties and Uses. — In large doses Simaruba is said to purge and vomit. In smaller doses it is tonic, and may be used in infusion in all cases where simple bitter tonics are indicated. It may be used in all cases as a substitute for quassia. It was at first introduced to the profession as a calmative astringent in chronic dysentery and diar- rhea. However, it merely acts as a tonic, proving beneficial in relaxed and debilitated states of the alimentary canal, and would do harm, if used indiscriminately in dysentery. The infusion is the best form, two or three drachms of the bark being added to a pint of boiling water, the dose of which, as a tonic, is from half a fluidounce to two fluidounces. Off.

Description. — Sinapis Alba is an annual plant, with a thinly hirsute stem, from two to five feet high. The leaves are smoothish, lyrately pin- nate, irregularly dentate, rugged, and pale-green ; the lower lobes oblong and deeper, the terminal larger. The flowers are in racemes, with yellow petals, and linear, green, calycine leaflets. The siliques or pods are spreading, hispid, torose at the place of the seeds, ribbed, shorter than the compressed, ensiform beak, and about four-seeded. The seeds are globose, large, and pale. Sinapis Nigra is also an annual plant, with a round, smooth, striate, branching stem from three to six feet high. The lower leaves are large, rough, variously lobed, and dentate; those higher on the stem more smooth and less lobed; and the uppermost are linear-lanceolate, entire, smooth, and pendulous; all are petiolate. The flowers are small, with yellowish, spreading calyx, and yellow, obovate petals, and stand closely together upon peduncles at the upper part of the branches. The pods are very numerous, nearly an inch long, bluntly quadrangular, nearly even and smooth, appressed close to the rachis of the raceme, tipped by a small, short, four-sided style, but wholly destitute of the ensiform 876 Materia Medica. beak of the above species. Seeds numerous, small, globose, blackish- brown, veined. History.—These plants are natives of Europe, and have been intro- duced into this country, where they are cultivated in gardens, and are found growing in old fields and waste places, flowering in June and July. The seeds of the Black Mustard are small, about the size of millet seed, globular, of a deep-brown color, slightly rugose on the surface, and internally yellow; when pulverized, they form a greenish-yellow powder, and have a faint smell when dry, but when mixed with water or vinegar, they have a peculiar, penetrating, diffusive odor, and a hot, bitterish, pungent, but not persistent taste. White Mustard seeds are nearly three times the size of the black, yellowish externally and in its substance, and of an odor and taste similar to the preceding, but more feeble; it affords a yellow powder, of a somewhat unctuous appearance, coalescing when compressed. Both kinds of mustard seed are employed in medi- cine, in the form of flour, and the white seeds are likewise used entire. Table mustard is prepared from the white seeds; but the finest quality is prepared with the purest flour of both the white and black, in nearly equal quantities. An English quality of table mustard is said to be prepared by mixing 145 pounds of mustard flour, made by grinding together two bushels of black and three of white seed, with fifty-six pounds of wheat flour, to diminish the pungency, and two pounds of tur- meric to improve the color; then to restore the acrimony without the pungency, one pound of chilly pods, and half a pound of ginger, is added. The officinal flour of mustard should be made with the black and white seeds only, without any adulteration. Upon pressure, both kinds of seed yield a fixed oil, thick like castor oil, of a greenish-yellow color, little smell, and a mild, not unpleasant taste, called Oil of Mustard, which yields upon saponification a peculiar acid, to which the name of Erucic Acid has been applied. When black mustard seeds have been deprived of their fixed oil by pressure, a volatile oil is then obtained from them by distillation with water, called the Volatile oil of mustard; it contains sulphur, is colorless, or pale-yellow, heavier than water, of an exceedingly pungent odor, and an acrid, burning taste; it is slightly soluble in water, but readily so in alcohol or ether. It boils at about 298°, and when treated with alkaline solutions, forms sulphocyanurets; with an equivalent of ammonia, it forms a white, inodorous, crystalline compound, possessing many of the characters of an organic base, called Thiosinnammin, Cs Hs N2 Sa. The volatile oil consists of nitrogen, carbon, hydrogen, and sulphur ; its for- mula is Cs Ho NS2, and its specific gravity 1.010. Dr. Will considers it a sulphocyanuret of allyle Cj Hs + C2 NS2. It is the active principle of black mustard seeds. Black mustard seed contains two peculiar principles, Myronic Acid, in the state of Myronate of potassa, and Myrosyne, an indifferent nitrogenized Sinapis Alba — Sinapis Nigra. 877 body, analogous in character to the emulsin of almonds. When the seeds are bruised and macerated in water, the myrosyne, acting the part of a ferment, causes a reaction between the water and myronate of potassa, which results in the production of the volatile oil. The same thing happens when any one of the myronates is brought into contact with water, and the essential fermenting principle, myrosyne. As with emulsin, Avhen coagulated by heat, alcohol, or acids, the myrosyne becomes inert, and no volatile oil is obtained. Myronate of potassa may be obtained by pulverizing black mustard seeds, drying the powder at a temperature of 212°, and then depriving it of its fixed oil by pressure. The powder is then to be treated with strong alcohol in a displacement apparatus, and when nearly exhausted of everything soluble in this liquid, it is to be again pressed, and then treated with water. The aqueous solution must next be evaporated, adding weak alcohol before it is too much concentrated, which precipi- tates a glutinous matter. The solution then being filtered, and carefully evaporated, deposits crystals of myronate of potassa, which may be obtained very pure and white by washing the mass with diluted alcohol. It is unalterable in the air, very soluble in water, insoluble in pure alco- hol, and of a bitter taste. Myronic acid may be obtained by adding to a solution of one hundred parts of myronate of potassa, thirty-eight parts of crystallized tartaric acid, concentrating the solution by evaporation, and then adding weak alcohol, which precipitates the bitartrate of potassa, and retains the myronic acid in solution. It is a fixed, inodorous substance, of a bitter and sour taste, and an acid reaction. When obtained separate from its bases, it forms a colorless solution, which, by evaporation becomes thick, like molasses, without crystallizing. It is soluble in water or alcohol, but not in ether; and forms soluble salts with the alkalies, baryta, lime, and the oxides of lead and silver, all of which yield volatile oil of mus- tard, when mixed with an aqueous solution of myrosyne. It contains sulphur, nitrogen, carbon, hydrogen, and oxygen. White mustard seeds contain myrosyne but no myronate of potassa, and consequently no volatile oil can be obtained from them; yet if they be added to black mustard seeds in which the myrosyne has been coagu- lated, the volatile oil will be generated on the application of water and distillation. Although no volatile oil is had from white mustard seed, yet upon the addition of water, a fatty acrid principle is developed, Avhich renders these seeds applicable to the same purposes as the black variety. This acrid principle is the result of the reaction of water upon sulpho-sina- pisin, a principle found in the seed, and which is accomplished through the presence and influence of myrosyne; for if this be absent, or coagu- lated by heat, alcohol, etc., no change takes place. Boutron and Fremy state that with the development of the fixed, fatty, inodorous, acrid 878 Materia Medica. principle, hydrosulphocyanic acid is also produced. White mustard seeds contain more fixed oil than the black. Sulpho-sinapisin may be obtained by freeing white mustard seeds of their fixed oil by expression, then boiling them in water, evaporating the decoction to the consistence of honey, mixing the residue with six or eio-ht times its volume of anhydrous alcohol, which precipitates vari- ous substances, then distilling off the alcohol, and setting the syrupy residue aside, to crystallize. The crystals may be purified by repeated solution in alcohol and crystallization. It is white, crystallizable, ino- dorous, bitter, and soluble in alcohol or water, forming yellow solutions. It is neutral, and consists of sulphur, nitrogen, carbon, hydrogen, and oxygen. Myrosyne may be procured by treating white mustard seed with cold water, filtering the solution, evaporating it by a heat not exceeding 100°, and when it is of the consistence of syrup, carefully adding alcohol, which causes a precipitate easily separable by decantation. If this precipitate be dissolved in water, and the solution cautiously evaporated as before, myrosyne, not entirely pure, is obtained. When dry, it has the character of an albuminous substance, is soluble in water, forming a viscid solution which froths Avhen agitated, and is coagulated and ren- dered inert by heat, alcohol, and the acids. Though closely analogous to emulsin, yet it is a distinct principle, as its place cannot be supplied by emulsin with the same results, and which is supposed by Simon to be owing to the absence of sulphur in the latter article. Simon obtained a peculiar principle by the following process, and which he called Sinajrisin: He exhausted black mustard seeds with strong alcohol, distilled off the greater part of the alcohol, treated the residue several times with four or five times its weight of ether, distilled off all the ether from the ethereal solutions, treated the extract again with a smaller quantity of ether so as to leave behind insoluble substances, and repeated this process until the extract formed a perfectly clear solution without residue. The extract was then dissolved in cold strong alcohol, and the solution, having been decolorized with animal charcoal, was alloAved to evaporate in the air. Fifty-five pounds of the seeds yielded only eighty grains of crystallized Sinapisin. It was in brilliant, white, scaly crystals, sublimable by heat, soluble in alcohol, ether, or the fixed and volatile oils, but insoluble in acids and alkalies. Upon contact with water and myrosyne, it emitted the odor of the oil of mustard. From the above statements, it will be perceived, that water at com- mon temperatures is the best vehicle for mustard, whether for internal or external use ; and that boiling, or uniting it with alcohol or acids, must impair its active properties. Properties and Uses.—Mustard is an irritant, stimulant, rubefacient, vesicant, and diuretic. It is used in small quantities, internally, as a Sisymbrium Officinale. 879 condiment, and safe stimulant of the digestive organs. In large doses it is a good emetic, and may be used in cases of torpor of the stomach, poisoning by narcotics, to rouse gastric susceptibilky, and also to facili- tate the action of other emetics. In inordinate doses it is poisonous, producing gastro-enteritis, and perverting the vital processes by its absorption into the system, as known by the horse-radish smell of the urine, and the mustard odor in the blood. Externally, it quickly excites redness of the skin, and if too long applied, inflammation, ulceration, and even sloughing ; but if removed in time, the redness is succeeded only by induration of the cuticle, and occasionally desquamation. ,The sting- ing pain Avhich remains after the removal of the mustard, may be miti- gated by sponging the part with cold water, or dropping ether on it. Sinapisms are beneficially applied over the abdomen and spine, in gas- tric and enteritic inflammations, and over the epigastrium, in vomiting from irritability of the stomach ; also to the spine, Avrists and ankles, to arouse the system in apoplectic and comatose conditions, and in typhus fever ; to the feet and legs, for pains in the head during fevers and other diseases, and in determinations to the head ; and to A'arious parts for removing pain, mitigating local inflammations, or arousing from stupor. In the treatment of cholera, mustard is an excellent rubefacient applica- tion, likewise in dyspepsia and obstinate constipation. Applied to the breasts it will often relieve suppression of the menses, as Avell as menor- rhagia ; to be applied intermittingly. In no case should a sinapism be continued too long, as vesication and ulceration followed by sphacelus, may result. The volatile oil of mustard, is a poAverful rubefacient and vesica- tory ; and in the dose of two drops, several times a day, in some muci- laginous vehicle, it is a good diuretic, useful in dropsy, and has been serviceable in colic. A liniment composed of one part of the oil, dissolved in sixteen parts of alcohol, or in ten parts of olive or almond oil, is a good substitute for a sinapism. White mustard seeds, taken entire, were formerly used as a favorite tonic in dyspepsia. Dose of mustard, as an emetic, one, two or three drachms, with six or eight ounces of warm Avater. Off.

Description.—This is an annual, herbaceous plant, with a round more or less hairy, branching stem, from one to three feet high. The leaves are runcinate ; the lower ones from three to eight inches long by one to three wide, the lower segments placed at right angles to the midvein, or 880 Materia Medica. pointing backward, the terminal segment largest; upper ones in three lanceolate segments placed at right angles. The flowers are small, yel- Ioav, and terminate the slender, virgate raceme, which becomes one or two feet lono-. The siliques or pods are subulate, erect, sessile, and closely appressed to the rachis. Seeds in a single row in each cell, ovoid, marginless. History.—This is an unsightly weed growing in the United States and Europe, along the roadsides, by walls and hedges, and on heaps of rub- bish, flowering from May to September. The whole plant is employed; it has a herbaceous, acrid taste, somewhat resembling mustard. The seeds have considerable pungency. Water extracts the active properties. Properties and Uses. — Diuretic and expectorant; recommended in chronic coughs, hoarseness, ulceration of the mouth and fauces, asthma, and urinary obstructions. The juice of the plant may be mixed with honey, or the seeds may be taken in substance. The Sisymbrium Sophia, or Flixweed, of a biting acrid taste, and pungent odor when rubbed, has been used externally in indolent ulcers, and the seeds internally in worms, calculous complaints, etc. Its leaves are bipinnately divided, the lobes oblong-linear, incised ; pedicels four times the length of the calyx; petals smaller than the sepals.

Description. — Smilax Officinalis has a twining, angular, prickly, and shrubby stem; the young shoots being unarmed. The leaves are ovate- oblong, acute, cordate, netted, five or seven-nerved, coriaceous, smooth, a foot long, and four or five inches broad ; the young ones lanceolate, oblong, acuminate, and tri-nerved. The petioles are an inch long, smooth, bearing tendrils above the base. Flowers unknown. The natives on the banks of the Magdalena river, in New Grenada, call this plant Zar- zaparilla, and send great quantities of it down the river to Carthagena and Mompox, from whence it is shipped for Jamaica and Cadiz. Pereira supposes this to be the Jamaica Sarsaparilla, the best and most valuable kind in commerce. It is not knoAvn, however, by this name in the United States, and differs from the Honduras sarsaparilla in the reddish color of its epidermis, and in containing less starch, and yielding a greater proportion of extract. It is usually had in bundles a foot or a foot and a half in length, by four or five inches in thickness, consisting of long slender roots folded up, with numerous radical fibers attached. Smilax Syphilitica has a round, smooth stem, furnished only at the joints with from two to four short, thick, straight prickles. The leaves Smilax Officinalis. 881 are a foot long, oblong-lanceolate, acuminate, shining, coriaceous, three- nerved, and terminated by a long point. This plant has been seen growing upon the banks of the river Cassiquiare in New Grenada, and in Brazil at Yupura, and near the Rio Negro. Pereira supposes it to yield the Lisbon or Brazilian Sarsaparilla, which is imported from Para and Maranham, in cylindrical bundles, from three to five feet long, and about a foot in thickness ; it is bound by close circular turns of a very flexible stem, and consist of unfolded roots, without rhizoma and stems, and with but feAv radical fibers. It has an amylaceous interior structure, with considerable acrimony. It is considered as a valuable variety of the drug. According to Richard it has been ascertained to be the pro- duct of the S. Papyracea of Poiret, instead of S. Syphilitica. Smilax Papyracea is an under shrub Avith a compressed stem angular below, and furnished with spines at the angles. The leaves are ellipti- cal, acuminate, and three-nerved. It inhabits Brazil, on the banks of the Amazon and its tributaries, and is thought to furnish the Brazilian Sarsaparilla. Smilax Medica has an angular stem, armed with straight prickles at the joints, and a few hooked ones in the intervals. The leaves are of the texture of paper, smooth, bright-green on both sides, cordate, auriculate, shortly acuminate, five-nerved, Avith the veins of the under- side prominent; they vary much in form, being ovate, somewhat pan- duriform, auriculate, and somewhat hastate, with the lobes of the base obtuse, sometimes obsolete, sometimes divaricating; their edge not straight, but as if irregularly crenate ; petioles and midrib armed, when old, with straight, subulate prickles. Peduncles smooth, axillary, vary- ing in length from three lines to an inch or more. Umbel about tAvelve- flowered, with the pedicels about three lines long. Schiede found this plant on the east slope of the Mexican Andes, where the root is col- lected and then carried to Vera Cruz ; it is supposed to furnish the Vera Cruz Sarsaparilla of commerce. This is imported from Vera Cruz and Tampico, in large, loose bales of about two hundred pounds each, bound with cord or leather thongs, and usually holding the roots folded upon themselves, and separately packed. These consist of a caudex, with numerous long radicles, smaller than in the Honduras variety, and having a thinner bark. They are frequently soiled with earth. Although not much esteemed, it possesses considerable acridity, and is, probably, not inferior to any of the other kinds. Smilax Sarsaparilla has a long, slender, shrubby, slightly four- angled stem, aculeate above. The leaves are unarmed, ovate, lanceolate, cuspidate, abruptly contracted at each end, with three strong veins, and two lateral smaller secondary ones, glaucous beneath, two or three inches in diameter, and supported alternately upon short, margined petioles with two long tendrils at their bases. The flowers are in small, 56 882 Materia Medica. thin umbels, yellowish-white, usually three or four together, upon a common peduncle which is longer than the petioles. The berries are three-seeded, red according to Woodville, black, to Pursh. This species is indio-enous, growing in swamps and hedges in the Middle and Southern States. It does not furnish any of the sarsaparilla of commerce, and is supposed to be destitute of any active medicinal properties, but on Avhat grounds I do not know. There is a plant in the South extensively known as Bamboo Brier, the root of which I have much used in practice, and with decidedly more successful results than from the use of any of the Sarsaparillas of the shops — from the description of the plant, given to me by those who have seen it growing, I am inclined to believe it is one of the species of Sarsaparilla, probably S. Sarsaparilla, and I invite the attention of Eclectics to it, as a remedy in every respect superior to the usual commercial article, especially in primary and secondary syphilitic diseases. Smilax China has a hard, large, knotty, uneven rhizoma, brown or blackish internally, whitish within. The stem is tapering, slightly prickly, growing two or three feet high Avithout support, but acquiring a greater length if scrambling among bushes. The leaves are thin, membranous, roundish, five-nerved, acute or obtuse at each end, and mucronate at the point ; the stipules are distinct, obtuse. Umbels small, ten-flowered, greenish-yellow. Fruit red, about the size of a bird cherry. This is a native of China and Japan, and has been employed under the name of China root as a substitute for the officinal Sarsaparilla. As found in the shops, it is in pieces from two to ten inches ]->ng, an inch or two in diameter, someAvhat compressed, more or less knotty, often branched, brownish or grayish-broAvn externally, whitish or light flesh color internally, inodorous, of an insipid taste at first, but succeeded by a slight bitterness and acridity, similar to that of sarsaparilla. History.—All of the Sarsaparilla plants are climbing or trailing plants, with prickly stems ; there are many species of them, some of which are destitute of any useful medicinal power. Hancock, among six or eight species grpwing in the Avoods of Guiana, found only one possessing any degree of medicinal activity. There are several varieties of the drug sarsaparilla in commerce, but from our present imperfect knowledge on the subject, we cannot determine with certainty the species which afford them. Those growing in Mexico and South America, have long and slender roots, originating in great numbers from a common head or rhizoma, from Avhich arise the stems of the plant. The Avhole root is usually dug up, with the rhizoma attached. Beside the varieties of this drug, heretofore referred to, there are one or two others, viz; the Caracas Sarsaparilla. from La Guayra. It comes in oblong packages of about one hundred pounds, surrounded with broad strips of hide, which are connected laterally with thongs of the same material, and leave much of the root exposed. The roots are separately and carefully packed. Smilax Officinalis. 883 Honduras Sarsaparilla is the variety most esteemed and more com- monly employed in this country. It comes from the bay of Honduras, and is in bundles two or three feet long, composed of several roots folded lengthwise, and compactly secured by a feAv circular turns. These are packed in bades of a hundred pounds or more, and are imper- fectly covered Avith skins. Externally the roots are of a dirty-grayish color, frequently re'cldish-brown, the epidermis is thin, inner bark thick, and the root is brittle, and so amylaceous when broken, that a fine white dust is easily driven out by rubbing it. Its botanical source is not accu- rately known. There are some other varieties of an inferior sort, which it is unnecessary to notice. The sarsaparilla of commerce is composed of roots of several feet in length, as thick or thicker than a goosequill, cylindrical, more or less wrinkled longitudinally, flexible, having a thick bark externally, covered with a thin, easily separable epidermis, an inner layer of ligneous fiber, and a central pith. The epidermis varies in color, but is mostly grayish, or reddish-brown, and occasionally very dark; the bark also varies in color, being whitish, broAvn, pink, and occasionally white, brittle, and pulverulent. The ligneous portion is thin, and is composed of longitu- dinal fibers, which allow the Avhole root to be readily split through its whole length. The central medulla often abounds in starch. The root is very faintly odorous, except when boiled in water, Avhich gives a decided and peculiar odor. Its taste is at first mucilaginous, but which gradually becomes slightly bitter and disagreeably and persistently acrid. Water, either cold or hot, readily extracts its virtues, Avhich are, however, much impaired by long boiling; diluted alcohol may also be used as a menstruum. According to Hancock, water does not take up all the active principle. In speaking of the Para and Rio Negro Sarsa- parilla, he states : " After exhausting half a pound of this sort by two digestions, boiling and pressure, I added to the dregs half a pint of proof spirit, and digested this with a gentle heat for a few hours in a close vessel, then affusing hot water to the amount of that taken off from the first boiling, and pressing again, I procured by the last operation about four pints of an infusion Avhich possessed the acrid properties of the sarsa in a much higher degree even than that obtained by the first decoction with simple water." There is no doubt, that alcohol added to infusions of the root, will increase their medicinal poAver, in consequence of its superior efficacy as a solvent. According to analysis, sarsaparilla contains a peculiar crystalline substance, a coloring matter, resin, starch, lignin, a thick, aromatic, fixed oil, a waxy substance, chloride of potas- sium, and nitrate of potassa. Also said to contain a minute proportion of volatile oil, gum, bassorin, albumen, gluten, gliadine, lactic and acetic acids, and various salts. The crystalline substance found in Sarsaparilla is supposed to be its active principle, and has been variously named by chemists. Palota, 884 Materia Medica. its first discoverer in 1824, named it Pariglin ; M. Folchi, supposing he had subsequently discovered a new principle, called it Smilacin. M. Thubeuf, in 1831, announced it as another newly-discovered principle under the name of Salseparin; and in 1833 M. Batka, from a similar supposition, gave an account of it as Parillinic acid, under an impres- sion that it contained acid properties. In 1834, M. Poggiale proved that all these substances are identical, though procured by different pro- cesses. If it is the active principle of sarsaparilla it should be named Sai-saparillin. The best process for obtaining it, is that of M. Thubeuf, as follows : Treat the bruised root with hot alcohol, until it is deprived of taste, distil the tincture and draw off seven-eighths of the alcohol; treat the remainder with animal charcoal, and at the end of twenty-four or forty-eight hours, filter. The sarsaparillin will be deposited in the form of a granular powder. This must be dissolved in a fresh portion of alcohol and crystallized. The alcoholic mother liquors may be de- prived of that portion of this principle which they retain, by evaporating to dryness, dissolving the product in Avater, filtering, again evaporating to dryness, redissolving in alcohol, and crystallizing. Sarsaparillin is white, inodorous, neutral, almost tasteless in the solid state, but of a bitter, acrid, nauseous taste, when dissolved in alcohol or water. It is sparingly soluble in cold water, but more readily in boiling water, which deposits it on cooling. Boiling alcohol also dissolves it more readily than cold ; and it is likewise soluble in ether and the volatile oils. The aqueous solution froths very much when agitated. It is found in the greatest abundance in the bark of the root. In doses of from two to thirteen grains, it has been found to produce nausea, and diminish the force of the circulation. M. Beral procured it pure, by preparing a tincture of the root Avith very dilute alcohol, and distilling by means of a salt-water bath. It is, therefore, volatile, and this explains the cause of the inefficiency of a long boiled decoction of sarsaparilla. Sarsaparilla should never be purchased, unless it leaves a decidedly acrid impression on the mouth and fauces, after having been chewed for a short time ; without this effect, it cannot be relied upon as an efficient article. Properties and Uses. — Sarsaparilla is generally considered as an alterative, though stated by some to possess diuretic, diaphoretic, and emetic properties. Its mode of action, however, is not well understood, as it effects normal changes in the system without any apparent influence over any of the functions. No medicine has, probably, ever passed through so many changes of reputation, having been at various times most highly lauded as an efficient alterative, and as often been pro- nounced inert. There is no doubt, however, that when properly pre- pared, it exerts a favorable influence over the system. The diseases in which it has been more particularly recommended, are inveterate Sodium. 885 syphilis, pseudo-syphilis, mercurio-syphilis, and struma in all its forms. It has also been advised in chronic rheumatism, chronic cutaneous diseases, passive general dropsy, gonorrheal neuralgia, and other de- praved conditions of the system, where an alterative is required. A beer is made in South America, which enjoys much reputation there as an alterative beverage ; it is made of Rio Negro Sarsaparilla one pound, raspings of guaiac wood six ounces, aniseed and bruised liquorice root, of each two ounces, mezereon root-bark one ounce, molasses one pound, and half a dozen bruised cloves ; pour upon these articles two gallons of boiling water, and shake the vessel three times a day. As soon as fer- mentation has well begun, it may be taken in doses of four fluidounces two or three times a day. At the present day, sarsaparilla is but little used by Eclectics ; the Stillingia Sylvatica being found greatly superior to it in medicinal efficacy, is employed in preference. Dose of sarsaparilla in powder, thirty grains, three or four times a day ; of the infusion or syrup, four fluidounces. Off.

Davy in 1807, while decomposing soda by means of galvanism. It was subsequently obtained in large quantities by Gay-Lussac and Thenard by means of iron turn- ings heated to whiteness; these coming in contact, the iron became oxidized, and sodium Avas liberated. The process of Schcedler is the most economical, as well as the most generally employed at the present day for procuring it—it is as follows: the commercial acetate of soda, is converted by ignition into carbonate and charcoal, which is heated in an iron-mercury bottle to whiteness, having had an additional portion of charcoal mixed with it; the process is similar to that for obtaining potas- sium, which see. Sodium is the metallic radical of the alkali soda. It is • a soft, sectile, silver-white metal, having a very high luster, but becom- ing quickly tarnished and oxidized when exposed to the air, from Avhich it rapidly absorbs oxygen, and must therefore be kept under naphtha. Its specific gravity is 0.97, it melts at 200°, its equivalent number is 23.3, and symbol Na. It fuses into a globule, when thrown upon cold water, and rapidly traverses the surface in all directions, liberating hydrogen, and generating a solution of soda, thus instantly decomposing the water. When exposed to the air, sodium forms the protoxide, or the alkali soda, which is the only important oxide, on account of its numerous salts. Sodium constitutes tAvo-fifths of all the sea-salt existing in salt water, in the water of springs, rivers, and lakes in almost all soils, and in the form of rock-salt. Sea-salt is a compound of sodium with chlorine, 886 Materia Medica. Na. CI. It is also contained in many minerals, sea-plants, and in most animal fluids. Sodium and the salts of the protoxide burn with a more or less rich yelloAV-colored flame. The medicinal salts of soda are chloride of sodium, solutions of soda and chlorinated soda, the acetate, borate, carbonate, bicarbonate, phos- phate, sulphate and valerianate of soda, and the tartrate of potassa and soda, each of which will be described under its appropriate head in the second part of this work." SOD^E ACETAS. Acetate of Soda. History.—Acetate of Soda, formerly called Crystallized Foliated Earth of Tartar, was first obtained in 1767 by Meyer. At present, it is pre- pared on a large scale by the manufacturer of pyroligneous acid, for the purpose of obtaining acetic acid by the action of sulphuric acid. The impure pyroligneous acid is neutralized with lime, forming an acetate of lime; this is treated with a strong solution of sulphate of soda, which by double decomposition produces a deposit of sulphate of lime, and acetate of soda in solution, which last is filtered and crystallized ; the crystals may be further purified by melting and re-crystallizing them. It may also be obtained by the following process of the Dublin College : Take of Crystallized Carbonate of Soda of commerce one pound (avoirdupois), or a sufficient quantity; Acetic Acid of commerce, sp. gr. 1.044, one pint (Imperial measure). To the Acid, placed in a porcelain capsule, add by degrees the Carbonate of Soda, and, taking care that there shall be a slight excess of Acid, evaporate the resulting solution until a pellicle begins to form on its surface, and set it by to crystallize. The crystals, when drained of the mother liquor, and dried by a short exposure to air on a porous brick, should be inclosed in a well-closed bottle. Acetate of Soda is a white salt, in amorphous foliated masses of inter- laced crystals, or crystallized in long striated needles and oblique rhom- bic prisms variously modified. It is permanent in ordinary air, but slowly effloresces in a dry atmosphere, losing about forty per cent, of its weight; its taste is cooling, saline, bitterish, but not disagreeable. It requires about three parts of temperate water to dissolve it, and about twenty-four parts of alcohol. It dissolves in less than its own weight of water at 212°. A temperature of 550°, cautiously managed, drives off its water of crystallization, without the loss of any acid ; but at 600° the acetic acid is decomposed, and a mixture of carbonate of soda and char- coal is left. Sulphuric acid decomposes it, setting free the acetic acid, which may be known by its peculiar acetous odor, and forming a sulphate of soda. A solution of acetate of soda is not acted on by chloride of platinum, which will serve to distinguish it from a salt of potassa. Ace- tate of soda should be perfectly neutral to test-paper. It consists of one equivalent of acid 51.48, one of soda 31.3, and six of water 54=136.78. Sod^e Boras. 887 Properties and Uses.—Acetate of soda is a mild diuretic, and possesses similar properties with the acetate of potassa. As a diuretic, its dose is from a scruple to two drachms. SOD^E BORAS. Borate of Soda. Borax. History.—Borax exists in a native state in several parts of the world, but more abundantly in the Avater of various lakes of Persia and Thibet, on the margins of Avhich it is left in impure crystals during the dry season, and is gathered in lumps, called Tincal or Crude Borax. It is also met with in the mines of Potosi; and is largely manufactured by the direct combination of boracic acid with soda. The crude borax or tincal comes from Thibet and various parts of Asia by the way of Cal- cutta, of which there are three varieties, Adz: Indian Tincal, which is met with in small crystals; Bengal or Chandenagor Tincal, which is in large, well-defined, hexaedral prismatic crystals; and Chinese Tincal, which is imported in crusts and masses, and is partially refined. The tincal met with in commerce is in crystalline masses, of a grayish, greenish, or yellowish color, opake, of a Avaxy luster, covered either with an argillaceous, or soapy substance, of a soapy odor, and greasy to the touch. Before being employed in medicine or in the arts, the various kinds of tincal require purifying. The mode of purifying crude borax was for many years known only to the Dutch and Venetians, Avho contrived to keep the process a secret; but in 1818 Robiquet and Marchand made known a process which is now generally adopted by refiners. It consists in placing the tineal in a large wooden vessel, covering it with water to the depth of four or five inches, and allowing it to remain thus, with occasional agitation, for six or seven hours; slaked lime is now added in the proportion of one part to four hundred of tincal, this is thoroughly mixed with the impure salt, and is then allowed to remain for twenty-four hours. The lime forms with the soapy matter an insoluble calcareous soap, and at the same time removes sulphate of soda, and chloride of sodium. The crude borax thus acted upon, is crumbled betAveen the hands, and placed upon a sieve to drain ; after the draining, it is dissolved in two and a half times its weight of water, by the aid of heat, and in order to separate any remains of the soapy matter, about one-fiftieth of its weight of chloride of calcium is added to the solution, after whieh it is strained. The solu- tion is then concentrated by evaporation, and run into wooden vessels of an inverted quadrangular pyramidal shape, which are lined with lead, and by allowing it to cool very slowly, distinct crystals of refined Borax are obtained; if the cooling takes place rapidly, crystalline crusts only will be furnished. 888 Materia Medica. At the present day, large quantities of borax are made artificially by the combination of boracic acid with soda. Boracic acid is obtained in great abundance from certain lagoons and hot springs in Tuscany, which are stated to furnish about three millions of pounds annually. It is impure when first obtained, containing in 100 parts 76.5 crystallized boracic acid, 8.5 sulphate of ammonia, 2.6 sulphate of magnesia, 5.0 sulphate of lime, 1.2 silica, 1.3 sulphuric acid, 6.6 Avater, beside various other impurities. Borax is prepared by saturating a solution of carbo- nate of soda with boracic acid, then evaporating and crystallizing, or by saturating caustic soda with boracic acid; the impurities existing in the acid are removed, after the biborate has been formed, by various processes. Borax crystallizes in large, oblique, rhombic prisms, or in flattened, six or eight-sided prisms, usually terminated by two or four converging planes ; it is white, translucent, shining, inodorous, and pos- sessed of a peculiar SAveetish, slightly saline and somewhat alkaline taste. It has an alkaline reaction. It slowly effloresces Avhen exposed to the air, its surface becoming covered with a Avhite powder. It dis- solves in twelve parts of cold, and two of boiling water; sulphuric acid added to a hot concentrated solution, causes a precipitate of white, pearly, scaly crystals of boracic acid, which, added to alcohol, impart a green color to its flame while burning. The sulphate of soda remains in solution. At a moderate heat, borax fuses in its water of crystalliza- tion, swells considerably, and ultimately becomes an anhydrous salt, having lost about half its weight. Above a red heat it fuses again into a liquid, which on cooling, concretes into a solid, transparent mass, called Glass of Borax, which is much used as a flux in assays with the blowpipe. When two parts of borax, and six parts of bitartrate of potassa, are boiled for five minutes, in sixteen parts of water, the solution filtered when cool, and then evaporated, a gummy mass is obtained, called Soluble Cream of Tartar; this is soluble in its own weight of cold, and half its weight of boiling water. Boracic acid renders the bitartrate of potassa still more soluble in water, than borax; four parts of the bitartrate and one of acid, boiled in twenty-four parts of water, and the solution evaporated, will likewise form soluble cream of tartar, the exact character of which is not satisfactorily known. Boracic acid is composed of one equivalent of boron 10.9, and three of oxygen 24=34.9 (B03). Borax consists of tAvo equivalents of boracic acid 69.8, one of soda 31.3, and ten of water 90=191.1 (2B03 +NaO + 10Aq). The boracic acid 4s so feeble an acid that even the two equivalents of it in borax do not fully neutralize the soda, so that borax is an alkaline salt. A variety of borax occurs containing only five equivalents of water; it crystallizes in octahedrons, is harder than com- mon borax, and does not effloresce. It may be obtained by crystalliz- ing a boiling solution of borax, at a temperature between 132° and 174Q. Borax is not subject to adulteration. Sod^e Carbonas. 889 Properties and Uses.—The medicinal actions of borax are but imper- fectly knoAvn. It is supposed to be a diuretic, refrigerant, antilithic, emmenagogue, and aphrodisiac. It has been found an excellent remedy in nephritic and calculous complaints, depending upon an excess of uric or lithic acid; the dose is from thirty to forty grains. It is rarely used as a parturient agent, yet there is no doubt that it exerts an action on the uterus. It has been successfully used in amenorrhea, dysmenorrhea, and to facilitate parturition, or favor the expulsion of the placenta. In such instances it has been used alone, or combined with other agents as ergot, blue cohosh, cinnamon, etc. Ten grains given for a dose, and repeated three or four times a day for several days, have produced abor- tion, attended with pains all over the system, and excessive debility of the joints, which remained for several months in a greater or less degree. It is an aphrodisiac, and will excite the venereal appetite when taken internally ; but its aphrodisiac effects are said to be more marked when a solution of it is injected into the rectum, and retained there an hour or two. A solution of ten or fifteen grains to the fluidounce of water, injected, will, in two or three hours, produce a poAverful venereal excite- ment.. And if the strength of the solution be doubled, it will cause powerful erections, and several copious seminal emissions. It is in extensive use as an external application in aphthous and inflam- matory affections of the mouth and throat, and in scaly cutaneous diseases. A solution of one drachm in five fluidounces of water, with a little sugar or honey, forms one of the best applications for use as a gargle in the early stage of mercurial salivation, and also in all varieties of aphthous ulceration of the mouth and throat. One drachm of borax dissolved in two fluidounces of distilled vinegar, is said to be an excel- lent lotion for ringworm of the scalp. In liver spots, (pityriasis versi- color), it has also been found beneficial, and in pruritus vulva, combined with morphia. Combined with sugar it forms an. excellent collyrium, and enters into several cooling or refrigerant lotions. The dose of borax is from ten to thirty grains, dissolved in water, or in infusion of elm or flaxseed. Off. Prep.—Lotio Boracis ; Lotio Boracis cum Morphiae. SOD^E CARBONAS. Carbonate of Soda. History.—Carbonate of Soda exists in a native state in various parts of the Avorld in mineral waters, lakes, and springs, or in the surface of the soil, which frequently exhibits a saline efflorescence. It sometimes occurs as a mineral in the form of sesquicarbonate, and is found abun- dantly in the ashes of marine and salt-marsh plants. Thus, it is found in Fiance in the waters of Vichy and of Vals, in Hungary in the waters of Bilin, and in Iceland in the Geyser springs; as a mineral, it is found 890 Materia Medica. in Hungary, Egypt, South America, and in Northern Africa. The prin- cipal part of the commercial salt is, however, prepared artificially, being much purer than that otherwise obtained. The ashes of marine plants furnish an impure soda, which is called Barilla, or Kelp. Barilla is obtained from a variety of plants, chiefly of the genera Salicornia, Sulsola, and Chenopodium. When ripe, these vegetables are cut down, dried, and burnt. The ashes contain from twenty-five to forty per cent, of carbonate of soda, and when of good quality, are in hard, dry, porous, sonorous, grayish-blue masses, which upon exposure to the air become covered with a saline efflorescence. Barilla is prepared chiefly in Spain and Sicily. Kelp is procured from various seaAveeds, principally the Algae and Fuci. The plants are allowed to ferment in heaps, then dried, and burnt. A large solid mass is formed, which is broken into small fragments. As found in com- merce, kelp is in hard, vesicular, dark-gray, bluish, or greenish masses, havino- a sulphurous odor, and a caustic acrid taste. It contains from five to eight per cent, only of carbonate of soda, and was formerly abundantly manufactured in Great Britain, and especially in the Orkney and Hebrides islands. The artificial salt is prepared by decomposing the sulphate of soda; which salt is more commonly made by converting common salt (chloride of sodium) into the sulphate, by means of sulphuric acid. The sulphate being thoroughly dried is intimately mixed with its weight of limestone- powder, or chalk, and half its weight of powdered pit-coal; the Avhole mixture is then subjected to a strong heat in a reverberatory furnace, and frequently turned over, till flames cease to be emitted, and a pasty, black mass is obtained called Black Ash, Black Soda-ash, Black Bulls, or British Barilla. When properly prepared this contains soda chiefly in the caustic state, and equivalent to about 55 per cent, of the dry car- bonate. When this is lixiviated and evaporated to perfect dryness, the soda becomes partly carbonated, and a white or gray compact substance is produced, which is called Soda-ash or White Soda-ash. The carbonate of soda is obtained by calcining this soda-ash in a reverberatory furnace, with its weight of sawdust or coal-dust, the temperature being maintained between 650° and 700°, till blue flames cease to issue; the sulphur is thus burnt all aAvay, and all the soda becomes carbonated. The result- ing mass is then lixiViated, concentrated till a pellicle forms on its surface, and then poured into tanks to crystallize. This mode of manu- facturing carbonate of soda, is pursued on an immense scale in Great Britain, especially at Liverpool and Glasgow. Carbonate of soda crystallizes in rhombic octahedres, or in large oblique rhombic prisms, or forms derived from the latter. These are colorless, transparent, alkaline, and disagreeable to the taste, speedily efflorescent in the air, soluble in twice their weight of cold water, inso- uble in alcohol, and having an alkaline reaction. At a moderate heat Sod^e Carbonas. 891 they lose their water of crystallization; if it be increased, they become converted into a Avhite, opake, anhydrous carbonate. The anhydrous salt is fused at a full red-heat. Carbonate of soda may be known from the carbonate of potassa by its crystalline appearance and disposition to effloresce — from bicarbonate of potassa by its efflorescence — from bicarbonate of soda, by that being never distinctly crystalline. In solu- tion, it may be discriminated from carbonate of potassa, by chloride of platinum, an excess of tartaric acid, or perchloric acid, occasioning no precipitate—and from bicarbonate of soda by giving a white precipitate with sulphate of magnesia, and a reddish-brown one with corrosive sub- limate. It is incompatible Avith acids, acidulous salts, lime-water, muriate of ammonia, and earthy and metallic salts. It consists of one equivalent of soda 31.3, one of carbonic acid 22.12, and ten of water 90 = 143.42. (Na 0 + 002 + 10 Aq.) The quantity of Avater may, however, vary in its proportion, owing to the degree of efflorescence of the salt. Sulphate of soda and chloride of sodium are the most common impu- rities met Avith; these may be detected by converting the carbonate into a nitrate, and then testing with chloride of barium, and nitrate of silver. When improperly prepared the salt is apt to contain some sulphuret of sodium, which may be known by the odor of sulphureted hydrogen which is emitted on dissolving it in Avater. Good carbonate of soda should be free from these impurities, though common salt is frequently present. Properties and Uses.—In large doses carbonate of soda is corrosive and irritant; in medicinal ones, it is antacid, antilithic, and resolvent. When an overdose is taken, the best antidotes are fixed oils, acetic acid, lemon-juice, or cream of tartar. It has been used in diseases attended with acidity of stomach, especially gout, uric acid, gravel, dyspepsia, sick-headache, etc. It is more easily taken, and is less acrid and disagreeable than the carbonate of potassa. As with all the alkaline carbonates, if too long employed, it may bring on phosphatic gravel through the alkalinity of the urine; on this account, the bicarbonates dissolved in carbonic acid-water and taken, are preferable, as the excess of carbonic acid tends to keep the phosphates in solution. It has been recommended in pertussis, scrofula, and bronchocele, and as an internal and external agent in scaly and papular cutaneous diseases. In these latter affections, a lotion may be made by dissolving two or three drachms of the carbonate in a pint of water; or a bath may be employed, holding from eight to sixteen ounces in solution in the neces- sary quantity of water; or an ointment may be used, composed of from eight to sixty grains to the ounce of lard. The dose of carbonate of soda is from ten to thirty grains in solution. Off.

SOD^E SULPHAS. Sulphate of Soda. History.—Sulphate of Soda, also known as Glauber's Salt, from its dis- coverer in 1658, and Vitriolated Soda, exists more or less abundantly in various mineral springs, in sea-water, and in the form of mineral com- bined Avith sulphate of lime. It is found in the mineral springs of Carls- bad, Cheltenham, Sulphur springs of Virginia, Saratoga Pavilion spring, Geyser springs, and Paipa among the Andes, in the latter of which, it is so abundant, that it forms crystals upon the soil over which the water is thrown. It is likewise prepared artificially in great quantity in the processes for procuring muriatic acid and chlorine, and in obtaining muriate of ammonia from common salt and sulphate of ammonia. In some of the NeAV England States, it is procured in the winter season from sea-water. The Edinburgh Pharmacopoeia gives the following formula for prepar- ing it: Dissolve two pounds of the salt which remains after the distillation of pure muriatic acid (which is a supersulphate of soda), in three pints, Imperial measure, of boiling water; then add white marble in powder so long as effervescence takes place, or to saturate the excess of acid, boil the liquid, and when neutral, filter it; wash the insoluble matter (sulphate of lime) with boiling water, and add the washings to the original liquid ; concentrate till a pellicle begins to form, and then set it aside to crystallize. Thomas, Dellisse, and Boucard have proposed a cheap process and which avoids the productions of muriatic acid vapors; it is by double decomposition between sulphate of iron, and chloride of sodium. Sulphate of soda crystallizes in large oblique rhombic prisms, often truncated on their acute edges so as to form six-sided prisms, and termi- nated by two, four, or six converging planes; when hastily crystallized, the crystals are small and acicular. Its crystalline form and general appearance resemble those of the sulphates of magnesia and zinc. It is colorless and transparent, possessing a cooling, bitter, saline, nauseous taste, and effloresces in the air, its surface becoming covered with an opake white poAvder. It is soluble in three times its weight of cold, and in its own weight of boiling water, and is insoluble in alcohol. Exposed to heat it fuses in its water of crystallization, which is expelled by an elevated heat, with the exception of one equivalent of water; this is removed, however, by a low red-heat, and at a full red-heat, the salt fuses again, losing 55£ per cent, of its weight. It is not subject to adul- teration, though it occasionally contains an excess of alkali or acid, which may be ascertained by turmeric or litmus paper. Salt may be detected by sulphate of silver; iron by tincture of galls, or ferrocyanu- ret of potassium. Sulphate of soda is incompatible with the salts of lime, baryta, and lead, carbonate of potassa, and nitrate of silver. It is Sodii Chloridum. 893 composed of one equivalent of soda 31.3, one of sulphuric acid 40, and ten of water 90=161.3 (Na 0 + SOa + 10 HO). Properties and Uses.—Sulphate of soda is cathartic, aperient, and diuretic, but on account of its disagreeable taste, it has gradually been displaced by the sulphate of magnesia. As a cathartic the dose is from four drachms to an ounce, dissolved in eight or ten ounces of water; as an aperient and diuretic the doses must be smaller, and largely diluted with water. As the salt by efflorescence loses about half its weight of water, when the effloresced article is used, the dose will be only one half of the above quantities. A few drops of sulphuric acid, or a little lemon-juice, or cream of tartar, added to the solution, will lessen its nauseous and bitter taste. SODII CHLORIDUM. Chloride of Sodium. History.—Chloride of Sodium (Sodae Murias, Muriate of Soda, Com mon salt), exists abundantly in nature either in solution, or in the solid state. In the state of solution it is found in many springs, lakes, and in sea-Avater, Avhich contains about 2.7 per cent, of it, and from which it is obtained either by spontaneous evaporation in warm countries, consti- tuting the bay-salt of commerce, which is in large grains approaching the cuboidal form, or, by concentrating the sea-wTater with the aid of heat, constituting the sea-salt of commerce, which is in small, white, irregular grains, tending to the cubic form. In the evaporation of sea water, sul- phate of lime is deposited in the early part of the process, and after the crystallization of the chloride of sodium, a large proportion of magnesian salts remain in the mother-water. All salt waters have the salt obtained by evaporation in large iron boilers, or by spontaneous evaporation, depending on the amount of salt contained in the water, and the tem- perature of the climate. In the solid state, salt is found in various parts of the Avorld, forming extensive beds, and even entire mountains, from which it is removed in blocks or large masses by mining operations ; in this state it is called Rock Salt, Fossil Salt, Gem Salt, etc. It is either transparent or translucent, exhibiting various colors, as red, yellow, blue, broAvn, etc., owing probably to the presence of manganese and iron, and from Avhich it may be purified by solution, and crystallization. In the United States a great amount of salt is made at Salina, Montezuma, Galena, on the Kanawha, etc., from saline springs which either flow naturally, or are produced artificially by sinking shafts to various depths in places where salt is known to exist. Although there are several varieties of salt recognized in commerce, the essential difference between them is in the size and density of the grains, rather than in a difference Of composition. Chloride of sodium by slow evaporation crystallizes in transparent, colorless, and regular cubes, but by hasty evaporation it forms hollow 894 Materia Medica. quadrangular pyramids. It is permanent in the air, but becomes moist on the surface in a damp atmosphere, or when chloride of magnesium is present. It is sparingly soluble in alcohol, and dissolves in two and two-third parts of cold water; boiling increases its solubility but very slightly. Heat causes it to decrepitate from the presence of water inclosed in the crystals ; a red heat fuses, and a white heat volatilizes it in white fumes without decomposition. It communicates a bright yellow hue to the flame of spirit. Nitrate of silver added to its solution occa- sions a curdy Avhite precipitate of muriate of silver, soluble in ammonia. It does not yield a yellow precipitate with chloride of platinum, or a crystalline deposit Avith tartaric acid, as is the case with chloride of potassa. It is very apt to contain sulphates of lime and magnesia, and chlorides of magnesium and calcium. Pure chloride of sodium is not precipitated by ferrocyanuret of potassium, carbonate of soda, or chlo- ride of barium. It is incompatible with nitric, sulphuric, and several other acids, carbonate of potassa, nitrate of silver, and protoxide of mercury. It is composed of one equivalent of chlorine 35.42, and one of sodium 23.3=58.72, Na+Cl. Properties and Uses.—Chloride of sodium in large doses is emetic and cathartic ; in small ones, tonic, alterative, and anthelmintic. It is useful in all chronic diseases characterized by a pale color of the tongue Avith a white coat or fur. In teaspoonful doses, taken dry, it often checks hemoptysis, and used moderately it promotes digestion, removes stru- mous diseases, cures seme forms of dyspepsia, and gives tone to the digestive organs of children, and corrects the disposition to generate worms. It proves a salutary stimulus even in health when taken in very small quantity, but an undue amount of it used daily, does, undoubtedly, in many persons dispose to plethora and corpulency. In spasms of an epileptic or apoplectic character, the effects of intemperance, salt and mustard, a teaspoonful or two of each, given in warm water, every ten or fifteen minutes, until free emesis is produced, will be found the most efficient emetic. In these cases, counter-in itation may be produced by bastinadoing the feet, and after the vomiting, the patient may drink freely of good fresh milk. During the cholera of 1849-50-51, in Cin- cinnati, much benefit was derived from the following mixture: Black Pepper, in powder, fine Table Salt, of each, one teaspoonful ; Vinegar, five teaspoonfuls ; Hot Water, half a tumblerful. Dose, a tablespoonful every five, ten, or fifteen minutes, as circumstances required. It speedily checked vomiting, abated the Avatery discharges, and removed the cramps. It succeeded in many cases, where every other means had failed. Externally, applied in solution, salt is useful as a fomentation in bruises or sprains, as a tonic and excitant application in depraved condi- tions of the system, as a collyrium in some ophthalmic diseases, and is frequently used as an ingredient in stimulating enemata. A pound of salt to four gallons of Avater forms a suitable salt-Avater bath, acting as a Solanum Dulcamara. 895 tonic and excitant in debilitated and strumous habits. The dose of salt as a tonic and alterative, is from ten to sixty grains. It has recently been recommended as a remedy in phthisis and intermittent fever. The entire absence of salt in the food, gives rise to a cachectic condition, and other morbid states, with the formation of an abundance of intestinal worms. Off.

Description. — BittersAveet or Woody Nightshade, is a woody vine, having a Avoody root, with a shrubby, flexuous, thornless and branching stem, several feet in length, and having a grayish-green bark on the stem and large branches. The leaves are alternate, acute, mostly smooth, though sometimes pubescent, veined, of a dull-green color, and petiolate; the loAver ones are ovate or cordate ; the upper, halbert-shaped, or with two ear-like lobes at the base, sometimes only one side; most of them are entire. The flowers are purple, and are disposed in branched cymose racemes, opposite, the leaves or terminal, drooping, divaricate, and on alternately subdivided peduncles. Bracts minute. The calyx is very small, acute, purplish, and divided into five persistent segments. The corolla is rotate, and consists of five purple reflexed segments, which are acute, ovate, Avith two roundish, shining greenish spots at the base of each. The fllaments are very short; the anthers erect, yelloAv, some- what connected into a conical tube. Ovary roundish, bearing a filiform style, longer than the anthers, Avith a simple, obtuse stigma. The fruit is a scarlet, oval, juicy berry, containing several whitish, plano-convex seeds. History.—Bittersweet, also known by the names of Violet-bloom, and Scarlet-berry, is common to both Europe and this country, growing in shady, fertile situations, especially where there is some moisture, and flowering from June to August. Its berries are ripened in autumn, and remain on the vine during most of the winter. There are several varie- ties of it, founded on the form of the leaves, and their smoothness or pubescence. The officinal portion are the small stems or tAvigs, though the Avhole plant is medicinal. The berries, when eaten, have certainly produced serious consequences, though considered by many to be innox- ious. The best time for gathering the twigs is in autumn, after the leaves have fallen ; those plants growing in high and dry situations are Eaid to be the best. 896 Materia Medica. When dried, the twigs are of various lengths, light, hollow, cylin- drical, about as thick as a goosequill, wrinkled, and of a grayish-ash color externally, and consisting of a thin bark, an interior woody portion, and a central pith. When fresh, they emit on being bruised, a peculiar, nauseous odor, and have a taste at first bitter, followed by some sweet- ness, and which has given origin to the name of the plant; when dried they are inodorous, but of the same taste with the fresh twigs. They impart their virtues to boiling water, and diluted alcohol; but long boiling destroys their activity. They are found to contain a sweetish, bitter extract, named Dulcamarin or Picroglycion ; a narcotic alkaloid, named Solania ; beside gum, gluten, and other unimportant ingredients. Its active principle is, probably, the solania. Several other species of Solanum have been employed medicinally. The Solanum Tuberosum or Common Potato is said to possess narcotic properties. An extract prepared from the leaves has been given in doses of from half a grain to two grains in cough and spasmodic affec- tions with advantage ; the stem and unripe berries have also been em- ployed. The extract has also been of service in chronic rheumatism and painful affections of the stomach and bowels. The potato itself, has been eaten in a raw state, either with or without vinegar, in cases of scurvy, and with good effect; occasionally it produced narcotic symp- toms, with a slight action on the bowels. Some practitioners have, how- ever, employed it in the above-named forms, without producing any sensible effect. Probably, cultivation, soil, climate, season, etc., exert some influence upon the properties of the plant. Dr. J. Otto found So- lania in the germs of the potato. The stalks of potato furnish a large quantity of potassa. If the stalks are cut while the plant is in flower, and the juice obtained by bruising and pressing, a bright yellow dye will be obtained. Solanum Lycopersicon, (Lycopersicon Esculentum,) or Tomato, is a native of South America. The fruit contains a peculiar acid, and a brown, tarry, odorous, resinous matter, with some indications of the presence of an alkaloid. It forms a very healthy article of food, and exerts a marked influence on the biliary functions. The leaves have a nauseous, narcotic odor, and contain an alkaloid very analogous to Sola- nia, a peculiar oil, and animal-extractive. Nearly all of the Solanums are possessed of nutritive or medicinal properties. Solania may be best obtained from the potato. In the beginning of June, collect the sprouts, and press them down in a suitable vessel, by means of pebbles. Then cover them with water acidulated with sulphu- ric acid, so as to have a strongly acid reaction during the maceration, and allow them to macerate for twelve or eighteen hours. Then express by hand, and the liquor, with the addition of fresh portions of sulphuric acid, is to be added twice successively, as at first, to fresh portions of sprouts, and in like manner separated by expression. After standing for Solanum Dulcamara. 897 some days, it must be filtered, and treated with powdered hydrate of lime in slight excess. The precipitate which forms, is to be separated by straining, dried in a warm air, and boiled several times in alcohol. The alcoholic solution, being filtered while hot, will upon cooling deposit the solania in flocculent crystals. An additional quantity of the alka- loid may be obtained by evaporating the mother liquor to one-fourth its volume, and then allowing it to cool. The whole residuary liquor will assume a gelatinous consistence, and, upon being dried, will leave the solania in the form of a translucent, horny, amorphous mass. Solania may be obtained impure from S. Dulcamara or S. Nigrum, by precipi- tating the expressed juice of the plant with ammonia, and then purifying by repeated solution in alcohol, and decolorizing with animal charcoal. When pure, solania is in the form of a white, opake powder, or of deli- cate acicular crystals, permanent in the air, inodorous, of a bitter taste, fusible at a little above 212° F., scarcely soluble in water, soluble in alcohol or ether, and neutralizing acids without forming crystallizable salts. Its solution becomes deep-brown or broAvnish-yellow on the addi- tion of iodine ; and sulphuric acid causes it to become at first reddish- yellow, then purplish-violet, then brown, and finally colorless, with a brown pulverulent precipitate. Solania has not been used in medicine ; two grains administered to a rabbit, produced symptoms of coma and paralysis, followed by death ; somewhat larger doses caused vomiting in dogs and cats, succeeded by drowsiness. Picroglycion may be obtained by treating the watery extract of S. Dulcamara with alcohol, evaporating the tincture, dissolving the residue in water, precipitating the solution with subacetate of lead, decomposing the excess of this salt by sulphureted hydrogen, then evaporating the liquor to dryness, and treating the residue with acetic ether. Upon spontaneous evaporation the principle is obtained in the form of small isolated crystals. Properties and Uses.—Solanum Dulcamara is feebly narcotic, diuretic, alterative, diaphoretic, and discutient. It has been chiefly used in syrup or decoction in cutaneous diseases, syphilitic diseases, rheumatic and cachectic affections, ill-conditioned ulcers, scrofula, indurations from milk, leucorrhea, jaundice, and obstructed menstruation. It is of more benefit in scaly cutaneous diseases, than others, as in lepra, psoriasis, and pityriasis, and especially when combined with guaiacum, and yellow dock root. When taken in large doses it produces nausea, vomiting, faintness, vertigo, and spasmodic action of the muscles. With many persons, the face and hands become purplish, and the circulation depressed while under its influence. It is said to be antaphrodisiac, and has proved useful in mania in which the venereal functions Avere strongly excited. Equal parts of the twigs, yellow dock root, and stillingia, made into a syrup, form a valuable preparation for scrofulous affections, 57 898 Materia Medica. as well as syphilitic. Externally, in the form of ointment, it is employed as a discutient to painful tumors, also as an application to some forms of cutaneous disease, ulcers, and erysipelatous affections. Dose of the decoction or syrup, one or tAvo fluidounces; of the extract, from two to five grains ; of the powdered leaves, from ten to thirty grains. Off. Prep.—Decoctum Solani. SOLANUM NIGRUM.

Description.—Solanum Nigrum is a fetid narcotic, bushy herb, with a fibrous root, and an erect, branching, angular, herbaceous, thornless stem, one or two feet in hight. The leaves are undivided, ovate, toothed and waved, smooth, lengthened out at the base, and almost always with the lamina perforated and the margin erose as if gnawed by insects. Umbels from the intermediate spaces between the leaves, solitary, pedun- cled, simple, doAvny, and nodding. Flowers white or pale-violet, with a musky scent; anthers yelloAv. Berries globose, black, about the size of peas. History.—The Garden or Deadly Nightshade, is found growing along old Avails, fences, and in gardens, in various parts of the United States, floAvering in July and August. There are several varieties of this spe- cies, of which the Solanum Virginianum is the most abundant in this country. It has an erect, prickly stem ; pinnatifid leaves, prickly on both sides ; divisions sinuate, obtuse; margin ciliate; calyx prickly, and flowers blue, or whitish. The leaves are the parts employed, and yield their properties to water, alcohol, or fixed oils. Properties and Uses.—Solanum Nigrum is a narcotic and sedative, producing, when given in large doses, nausea, and giddiness. One to three grains of the leaves infused in water, will, it is said, produce a copious perspiration, and often purge on the next day. They have been used in cancerous, scrofulous and scorbutic diseases, being given inter- nally, and at the same time, applied to the affected parts in the form of poultice or ointment. Solania exists in it more abundantly than in the S. Dulcamara, to which'it is somewhat analogous in medicinal proper- ties, with more active and energetic narcotic virtues. The berries are poisonous, causing torpor, burning in the stomach, fever, nausea, stupor, and insensibility ; though this is denied by M. Dunal of Montpelier. The plant is used by Eclectics in the form of ointment only, as a discutient. Off. Prep.—Unguentum Stramonii Compositum. Solid ago Odora. 899 SOLIDAGO ODORA. Sweet-scented Goldenrod. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Superflua. the leaves. Description.—This plant is also known as Fragrant-leaved Goldenrod, and Sweet Goldenrod; it has a perennial, woody, much branched and creeping root, and a slender, round, yellowish-green stem, smooth or slightly pubescent below, pubescent at top, often reclined, and two or three feet in hight. The leaves are closely sessile, linear-lanceolate, broad at base, entire, acute, rough at the margin but otherwise smooth, with a prominent midrib, and covered with small pellucid dots. The flowers are of a deep golden-yellow color, and are arranged in a termi- nal, compound, and usually secund-paniculate raceme, the branches of which are very slender, rigid, and spread almost horizontally, are each accompanied by a small leaf, and support the flowers on downy pedicels, which put forth from the upper side of the peduncle, and have small, linear, subulate bracts at their base. Scales of the involucre oblong, acute, smooth, or slightly pubescent, the lower ones shorter, and closely imbricating the rest. Florets of the ray few, with oblong, obtuse, yellow ligules ; those of the disk funnel-shaped, with acute segments. Pappus shorter than the florets of the disk. (The leaves of this plant are from an inch and a half to three inches long by from three to five lines broad, with a strong, yellowish midvein, but no veinlets.) History.—This is one of an extensive genus of herbaceous perennials, most of the species of which are natives of North America; their general character is that of mild astringency, combined in a few species with some aromatic stimulating qualities. The S. Odora is a native of most parts of the United States, growing in dry or sandy soil, and flowering from July to October. The leaves are the officinal portion, they have a fragrant odor, partaking of anise and sassafras, more perceptible on bruising them, and a warm, aromatic, agreeable taste, which properties depend on a pale-greenish-yellow volatile oil, lighter than water, and which'maybe obtained by distillation with water. When properly dried the leaves form an excellent substitute for tea. They impart their vir- tues to alcohol, or boiling water in infusion ; but boiling injures them. Properties and Uses.—Sweet scented Goldenrod is moderately stimu- lant, aromatic, and carminative; and in warm infusion, diaphoretic. It may be given to allay flatulence, nausea, and to cover the taste, or cor- rect the operation of unpleasant or irritating medicines. The oil is car- minative and diuretic : and its tincture, or essence, has been used as a diuretic in suppression of urine among infants, and as an external appli- cation in headache. Its essence is useful in flatulency, to arrest vomit- ing and spasmodic pains in the stomach, and to disguise the taste of 900 Materia Medica. nauseous medicines. The flowers are said to be aperient, tonic, astrin- gent, and diuretic, and have been found beneficial in gravel, urinary obstructions, ulceration of the bladder, and in the early stage of dropsy; taken in infusion. SOLIDAGO RIGIDA. Hardleaf Goldenrod. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Superflua. THE LEAVES AND BLOSSOMS. Description.—This plant is also termed Rigid Goldenrod; it has a sim- ple stem, corymbose above, terete, round, striate, rough, minutely hairy, very leafy, and from three to five feet in hight. The leaves are from one to four inches long, ovate-oblong, rough, with minute, rigid hairs; the upper ones being entire, veiny, thick and rigid; the lower closely sessile, by a broad base, slightly serrate; the radical ones lanceolate, acuminate, nerved, petiolate, sometimes near a foot long, and about two or two and a half inches broad. The flowers are all yellow, and arranged in a terminal, compound, close, compact, paniculate-raceme. Heads very large, about thirty-four flowered ; rays twice the length of the obtuse involucre, deep-yellow, from seven to ten, and about three lines by one. Scales of the involucre round-obtuse, nerved, membra- naceous at the edges. History.—This is a tall species growing in dry fields and rocky woods throughout the United States, and is abundant in the Western prairies, flowering in August and September. It is the styptic plant of old Dr. Bone, of New Jersey, who is said to have suppressed hemorrhages from large blood-vessels, by applying it locally, in the powdered state ; a pro- perty likewise attributed to the Solidago Virgaurea or European Golden- rod, found in this country and Europe. The leaves and blossoms of S. Rigida are the parts employed; they have an astringent taste, and yield their virtues to water or alcohol. Properties and Uses.—Hardleaf Goldenrod is tonic, astringent, and styptic. In powder or infusion, it is beneficial in all external hemor- rhages, epistaxis, hemotypsis, hematemesis, and hemorrhage from the bowels. Applied with excellent effect in form of poultice, to old ulcers. The oil is diuretic. The plant deserves further investigation. SPIGELIA MARILANDICA. Pinkroot. Nat. Ord. — Rubiaceas; Suborder, Spigelieae. Sex. Syst. — Pentandria Monogynia. THE ROOT. Description.—Botanists vary in their arrangement of this plant; beside the above given order and suborder, we find it classed in the natural Spigelia Marilandica. 901 order Gentianacece, also Spigeliacece, and again Loganiacece. It is usually known as the Carolina Pink, or Worm-grass. It is a herbaceous, indi- genous plant, with a perennial, very fibrous, yellow root, which sends up several erect, simple, nearly smooth, four-angled stems, of a purplish color, and from six to twenty inches high. The leaves are opposite, ses- sile, ovate-lanceolate, acute or acuminate, entire, and smooth, with the margin and veins roughish-hairy ; they are three or four inches long by an inch and a half, or two inches and a half broad, and the stipules are scarcely perceptible. The flowers are few in number, are arranged in a terminal, secund spike, and supported on short pedicels; they are somewhat club-shaped, scarlet externally, yellow internally, and from an inch and a half to two inches in length. The calyx is persistent, with five long, linear, subulate, finely serrulate divisions, which are reflexed in the ripe fruit. The corolla is funnel-shaped, four times as long as the calyx, the tube inflated in the middle and angular at top, and divided into five acute, spreading segments, the edges of which are slightly tinged with green. The stamens are short, inserted into the mouth of the corolla between the segments; anthers oblong, heart-shaped, exserted. Ovary small, superior, ovate; style about the length of the corolla, jointed near its base, and terminating in a linear, fusiform, fringed stigma, projecting considerably beyond the corolla. The cap- sule is double, consisting of two cohering, one-celled, globular carpels attached to a common receptacle, and containing numerous, small, angu- lar seeds. History.—This plant is a native of the United States, growing in dry rich soils, and on the borders of woods, seldom found north of the Poto- mac, and flowering from May to July. There are several varieties, both as regards the form of the leaves and the color of the flowers. It was known to the natives as a vermifuge, and was in use among the early colonists in the Southern States a long time before it became known to the profession, to whom it was introduced by Drs. Garden, Lining, and Chalmers, of South Carolina. As received at present, spigelia is in bales or casks, consisting almost exclusively of the root, without the stem or leaves; that contained in casks is less liable to become damp and moldy, and is consequently preferred to that in bales. The officinal part is the root; this consists of numerous, slender, branching, crooked, wrinkled fibers, from three to six inches long, forming a dense bunch, and arising from a short rhizome, which exhibits traces of the stems of former years. Externally it is brown or yellowish-brown, of a feeble, peculiar odor, and a sweetish, slightly bitter, not very unpleasant taste. Boiling water extracts its medicinal qualities. Analysis has detected in it fixed and volatile oil, a small quantity of resin, a brown-colored extrac- tive of a bitter and nauseous taste, on which the vermifuge power proba- bly depends, a mucilaginous saccharine matter, albumen, gallic acid, some salts, etc. A long, slender, crooked, yellowish root, thickly set 902 Materia Medica. with short capillary fibers, and much smaller and lighter colored than the pinkroot, will sometimes be found mixed with it; these are the roots, chiefly, of a small vine which attaches itself to the stem of the spigelia, and should be separated before using the medicine. Age im- pairs the activity of pinkroot. The leaves and stalks of spigelia should always be rejected. Properties and Uses.—Pinkroot is an active and certain anthelmintic, especially for children. In large doses, it is apt to purge, and likewise produce symptoms of narcotism, exciting the circulation, determining the blood to the brain, giving rise to vertigo, dimness of vision, dilated pupils, spasms of the facial muscles, and sometimes even causing con- vulsions. Spasmodic movements of the eyelids are among its most common attendants. These narcotic effects are less liable to occur when the medicine purges, and are entirely obviated by combining it with cathartics. Dose, of the powder, for a child three years old, from ten to twenty grains, or a fluidounce or two of a strong infusion, to be given at bed-time, followed in the morning by a cathartic. It is also useful in those conditions of the system, caused by worms, which resemble infantile remittent and other febrile diseases, and hydrocephalus. A well known worm tea is composed of pinkroot half an ounce ; senna two drachms ; savin half a drachm; manna two drachms. Mix, and infuse in a pint of water; dose one or two fluidounces. Dose of powdered pinkroot for an adult, one or two drachms twice a day for several successive days, and then followed by a cathartic. Off.

Description.—This plant, known also by the names of Meadow-sweet, White-leaf, and Steeple-bush, is a small shrub, from two to four feet in hight, with many, simple, erect, round, downy, hard, brittle and pur- plish stems, furnished with alternate leaves, crowded on very short peti- oles. The leaves are from an inch and a half to two inches long, and about half as wide, ovate-lanceolate, or oblong, unequally serrate, some- what acute at both ends, smoothish and dark-green, or brownish above, and covered with a rusty white, dense tomentum beneath. The flowers are small, very numerous, subsessile, beautifully red or purple, and are disposed in very short, dense, slender, compound, terminal spikes or racemes. The calyx is campanulate, with five acute segments. The petals are five, round. The stamens are numerous, exserted and con- Spirit Vapor-Bath. 903 spicuous. Styles five; carpels five, tomentose and spreading; seeds sub- ulate at each end. History.—This is a beautiful shrub, common in low grounds and mea- dows, in most parts of the United States, and flowering in July and August. The whole plant is officinal. As found in the shops, it is in packages of various sizes, containing a mixture of leaves and flowers, and frequently the bark. Its odor is somewhat similar to that of black tea, and its taste bitter and exceedingly astringent. Water extracts its medicinal virtues. It has not been analyzed thoroughly, but is known to contain bitter extractive, tannic and gallic acids. The fruit is per- sistent, .remaining through the winter, and furnishing food for the snow- bird. Properties and Uses. — Hardhack is tonic and astringent; useful in diarrhea, cholera infantum, and other complaints in which astringents are indicated, and is less apt to disagree with the stomach than most other astringents. As a tonic, it may be used in cases of debility, with want of appetite. The best form of administration is an extract, made by displacement, and evaporation in a water-bath, which affords a beau- tiful article, of an agreeable odor, and astringent, bitter taste, that is fully equal to catechu, and might replace it in all cases where that medicine is required ; the dose is from two to ten grains. Dose of the decoction, one or two fluidounces. SPIRIT VAPOR-BATH. History and Uses.—A spirit vapor-bath exerts a most powerful, yet beneficial influence upon the whole system, aiding very materially our endeavors to remove disease. This highly valuable mode of producing activity of the cutaneous vessels has long been practiced in many sections of the country as a domestic remedial agent, and was first intro- duced to the notice of the medical profession by myself, about eighteen years ago, since which it is in much use among physicians. The advantages to be derived from this method of producing perspiration are very great, and it is not followed with any of those injurious conse- quences which often attend the internal administration of a sudorific. It is to be given as folloAvs: The patient is undressed, ready for getting into bed, having removed the shirt and underclothing worn through the day, and put on a night shirt or other clothing to be Avorn only while sweating, and during the night, if the bath is taken at bed- time. He is then seated on a high Windsor, or wooden bottomed chair, or instead thereof, a bench or board may be placed on a common open bottomed chair, care being taken that the bottom is so covered that the flame will not burn him. After seating himself, a large blanket or coverlid is thrown around him from behind, covering the back part of his head and body, as well as the chair, and another must be passed 904 Materia Medica. around him in front, which last is to be pinned at the neck, loosely, so that he can raise it and cover his face, or remove it down from his face, from time to time, as occasion requires, during the operation of the bath. The blankets must reach down to the floor, and cover each other at the sides, so as to retain the vapor, and prevent it from passing off. This having been done, a saucer or tin vessel, into which is put one or two tablespoonfuls of whisky, brandy, spirits, alcohol, or any liquor that will burn, is then placed upon the floor, directly under the center of the bottom of the chair, raising a part of the blanket from behind to place it there; then light a piece of paper, apply the flame to the liquor, and as soon as it kindles, let down the part of the blanket which has been raised, and allow the liquor to burn till it is consumed, watching it from time to time to see that the blankets are not burned. As soon as consumed, put more liquor into the saucer, about as much as before, and again set it on fire ; being very careful to pour no liquor into the saucer while the flame exists, as there would be danger of burning the patient, blankets, and perhaps the house. Continue this until the patient sweats or perspires freely, which in a majority of cases will be in five or ten minutes. If, during the operation, the patient feels faint or thirsty, cold water must be sprinkled or dashed in his face, or he may drink one or two swalloAvs of it; and in some cases, the head may be bathed with cold water. As soon as free perspiration is produced, wrap the blankets around him, place him in bed, and cover him up warm, giving him about a pint of either good store tea, ginger, or some herb tea to drink, as warm as he can take it. After two or three hours, remove the covering, piece by piece, at intervals of twenty or twenty-five minutes between each, that he may gradually cease perspiring. There is no danger of taking cold after this spirit vapor-bath, if the patient uses ordinary precaution ; and if his disease will allow, he can attend to his business on the next day the same as usual. In fact, the whole is a very easy, safe, agreeable and beneficial operation ; much more so than a mere reading of the above explanation would lead one to suppose. Chairs are now manufactured expressly for this purpose. This kind of bath is peculiar to Eclectics, and is highly beneficial in colds, pleurisy, and all febrile and inflammatory attacks, diarrhea, dysentery, sluggishness of cutaneous vessels, and in all chronic disease where there is an abnormal condition of the skin. In acute diseases, it may be repeated once a day, if required ; in chronic diseases, once or twice a week, or once in a fortnight, according to indications. Where it can be done, it is always preferable to bathe the patient with an alkaline wash, both before and after this vapor-bath. Spiritus Pyroxilicus — Shell-lac Splints. 905 SPIRITUS PYROXILICUS. Pyroxylic Spirit. History.—This substance was discovered in 1812 by P. Taylor, since which it has been examined by various chemists; it has been called, Pyroligneous Ether, Wood-Naphtha, Wood Spirit, Wood Alcohol, Pyroxy- lic Alcohol, Methylic Alcohol, Hydrated Oxide of Methyle, etc. When wood is subjected to destructive distillation, there is formed, beside acetic acid, tar, and other products, about one per cent, of an inflammable, volatile liquid, which when separated and purified, consti- tutes pyroxylic acid. Pure anhydrous pyroxylic spirit is a mobile, colorless liquid, having a hot and pungent taste, and an aromatic odor, similar to that of acetic ether ; it readily combines with water, alcohol, or ether, without disturbing its transparency. It burns like alcohol, the flame, however, being less luminous, and resembles it as a solvent, as all bodies that are soluble in alcohol are likewise soluble in pyroxylic spirit. Its specific gravity as a liquid is 0.798 ; as a vapor 1.042. At 140° it boils, and its vapor causes concussions which render its distilla- tion difficult, but which may be prevented by placing in the bottom of the vessel, a layer of mercury. It is sometimes confounded with pyro- acetic spirit, which may be distinguished by adding a few drops of a saturated solution of chloride of calcium, which dissolves in the pyro- xylic spirit, but has no action on the latter, separating from it after agitation. The liquid examined must be sufficiently pure not to separate into two layers, nor to become milky on the addition of water. Properties and Uses.—Used to palliate consumptive cough, and lessen the febrile excitement attending phthisis. It appears to act as a nar- cotic, sedative, and anti-emetic. It arrests or greatly mitigates chronic vomiting, whether dependent on functional or organic diseases ; and is reputed efficacious in diarrhea and dysentery. Recommended by Dr. John Hastings in consumption, but is inefficient as a curative agent. Dose, ten to forty drops, three times a day; sufficiently diluted with water. A crude pyroxilic spirit of sp. gr. 0.846 to 0.890, is used by chemists to burn in lamps as a substitute for alcohol; and by hatters and varnish makers for dissolving resinous substances. SHELL-LAC SPLINTS. Preparation.—Take of finely pulverized shell-lac one pound, alcohol, 90 per cent, one quart; mix, and expose it to a moderate heat in a loosely stopped bottle, for forty-eight hours, when the shell-lac will be dissolved. With this solution saturate woolen cloth, and allow it to dry. To apply and fit the cloth to any part, cut it into the proper shape, and then hold it near a fire or hot stove, or dip it into boiling water, when it will become soft and pliable. As soon as it has cooled so as 906 Materia Medica. not to burn the patient, apply it to the part, and by holding it for a few minutes, or by the application of the bandage while it is yet pliable, it will assume any form desired, and on cooling, it becomes hard, and remains exactly as at first placed. If it is desirable to strengthen the splint, take two pieces of the saturated cloth, spread one side of each with a thick coat of the solution, by means of a common paint-brush, alloAv the alcohol to evaporate, and then, placing these two coated sides together, press them with a hot flat-iron, until they have become per- fectly cemented. This operation may be repeated several times, if it is necessary to increase the strength of the cloth, or splint. SPONGIA. Sponge. History,.—Sponge is a flexible, fixed, torpid, polymorphous animal, composed either of reticulate fibers, or masses of small spires interwoven together, and clothed with a gelatinous flesh, full of small mouths on its surface, by which it absorbs and ejects water. They inhabit the bottom of the sea, where they are fixed to rocks, or other solid bodies, and are most abundant Avithin the tropics. The coarser kind are imported from the Bahamas ; but the finest and best sponges are brought from the Mediterranean. Sponge, as in the shops, is in yellowish-brown masses, of various shape and size, light, porous, elastic, and composed of fine, flexible, tenacious fibers, interAvoven in the form of cells or meshes. It usually contains numerous minute fragments of coral, stone, or small shells, from which it must be freed before it can be used for ordinary purposes. Sponge is prepared by macerating it for several days in cold Avater, beating it, in order to break up the concretions which it contains, and dissolving what cannot thus be separated of the calcareous matter by muriatic acid, diluted with thirty parts of water. By this process it is rendered perfectly soft and fit for surgical use; and when intended for surgical purposes, the softest, finest, and most elastic sponges should be selected. For forming burnt sponge, the coarser will answer equally well. Sponge contains gelatin, coagulated albumen, iodine, common salt, sul- phur, phosphorus, carbonate of lime, magnesia, silica, iron, bromine, etc. Properties and Uses. — In consequence of its softness, porosity, and property of imbibing liquids, sponge is very useful in surgical opera- tions. It may likewise be advantageously applied over certain ulcers, the irritating sanies from which it removes by absorption. Compressed upon a bleeding vessel, it is useful for promoting the coagulation of blood in epistaxis and external hemorrhages. Dipped in wax, and flattened, and then cut into the size and form required, it forms the sponge tent, useful for dilating sinuses. It has likewise been used for producing pre- mature delivery, by introducing a piece of sponge into the mouth of the Spongia Usta — Staphylea Trifolia. 907 uterus, and allowing it to remain there for a time, and then changing it, until by its swelling, and the irritation it produces, uterine contractions are caused. SPONGIA USTA. Burnt Sponge. Preparation.—Take of sponge a convenient quantity, cut it into pieces, and beat it, that any extraneous matters may be separated, then burn it in a close iron vessel until it becomes black and friable, lastly rub it into very fine poAvder. History.—In 1000 parts of sponge, 343.848 were dissipated by calci- nation ; the remainder consisted of 327.0 parts of carbon and insoluble matters, 112.08 of chloride of sodium, 16.43 of sulphate of lime, 21.422 of iodide of sodium, 7.57 of bromide of magnesium, 103.2 of carbonate of lime, 35.0 of phosphate of lime, 4.73 of magnesia, and 28.72 of oxide of iron. The efficacy of burnt sponge depends princi- pally upon the presence of iodine, and should always be used when of recent calcination, as it becomes impaired rapidly in consequence of the volatilization of the iodine. Properties and Uses.—Said to be alterative and antiscrofulous. Used in goitre, scrofulous tumors, and obstinate cutaneous eruptions. Dose, from one to three drachms, mixed with syrup or honey, in the form of an electuary. A pill, which has acquired some considerable reputation in the cure of scrofula, is made as follows: Take of iodine fifty grains; sulphate of morphia ten grains; burnt sponge one hundred grains. Triturate these well together, and into a fine powder, and then form the mixture into a pill mass, by the addition of molasses or other compatible medium, and divide into one hundred pills. To be kept in a dry place. Dose, two or three pills daily. STAPHYLEA TRIFOLIA. Bladder-nut. Nat. Ord.—Celastraceae. Sex. Syst.—Pentandria Trigynia. the bark of the root. Description.—This is a handsome shrub, from six to ten feet in hight, with greenish, striped branches. The leaves are opposite, ternate; the leaflets oval-acuminate, serrate, pale beneath, with scattered hairs. The flowers are white, or yellowish-white, half an inch long, and in a short, pendulous raceme, terminating the branchlets. The calyx is composed of five, colored, persistent sepals; the petals are five, ciliate below; the fruit is ovate. When in flower, if the germ be cut transversely and examined, it will appear two or three-celled, and will contain the rudi- ments of fifteen or twenty seeds; but when the fruit is ripe, it consists 908 Materia Medica. of two or three inflated, adnate, submembranous capsules, which are three-sided, three-parted at top, three-celled, and contain several hard, small nuts or seeds, with a bony, smooth, and polished testa. History.—This plant is common to the United States, growing in moist woods and thickets, and flowering in May. By some it has been erro- neously called Swamp-Dogwood. The bark of the root is the officinal part, and has a pleasant, bitter taste. It yields its properties to water. No analysis has yet been made of this new Eclectic medical agent. Properties and Uses. — Practitioners must be careful to distinguish this bark from that of the Ptelea Trifoliata, with which it is frequently confounded, although there is but little resemblance between them; the Staphylea being a thin, hard bark, free from any oily taste or smell. Prof. I. G. Jones states that this bark is a pure, unirritating tonic, having rather a soothing influence when applied to irritated mucous membranes. He has employed it advantageously in convalescence after fevers, and in debility connected with gastro-enteric irritation. It promotes the appetite, enables the stomach to endure suitable nourishment, favors the early re-establishment of digestion, and will be tolerated by the stomach, when other tonics are rejected. He employs it in cold infusion, of which half a fluidounce may be given every two, three, or four hours, accord- ing to circumstances. It is also said to cure intermittent fever, and is considered by some to be equal to quinia. An extract maybe made of the bark of the root, and will be found valuable as a tonic; the dose of which is from three to five grains. Off. Prep.—Infusum Staphyleae. STATICE CAROLINIANA. Marsh Rosemary. Nat. Ord.—Plumbaginacete. Sex. Syst.—Pentandria Pentagynia. THE ROOT. Description. — By some botanists this plant is considered as a mere variety of the Statice Limonium of Europe, but the difference consists in the American plant having flat-margined and cuneiform leaves, while in the European species the leaves are oblong with undulated margins, and the flowers much larger. Statice Caroliniana is also known by the names of Sea-Lavender, Ink-root, etc.; it is an indigenous maritime plant, with a perennial, large, fleshy, fusiform or branched root, of a brownish color, which sends up annually a scape and leaves. The leaves are all radical, petiolate, erect, smooth, mucronate, entire, and veinless. The scape is round, smooth, terete, from six to eighteen inches in hight; paniculate above, divisions alternate, bearing unilateral spikes of small, bluish-purple, somewhat sessile flowers, each with two scaly mucronate bracts. The calyx is funnel-shaped, five-toothed, five-angled, Stellaria Media. 909 the angles ciliate; corolla deeply five-cleft, divisions spatulate, obtuse, longer than the calyx. Stamens five, inserted on the claAvs of the corolla; anthers heart-shaped. Ovary superior, small, and obovate, supporting five styles shorter than the stamens. Fruit or seed oblong, invested with the persistent calyx. History.—Marsh rosemary is found along the seacoast in marshy situ- ations from Maine to Florida, flowering from August to October. The officinal part is the root, which is large, fusiform or branched, heavy, fleshy, and of a reddish or purplish-brown color; it is inodorous, but has a saltish, extremely bitter and astringent taste. It imparts its vir- tues to alcohol, and more readily to boiling water. Mr. E. Parrish found it to contain about 12 per cent, of tannic acid, some gum, extrac- tive, albumen, resin, volatile oil, caoutchouc, lignin, coloring matter, and various salts. Properties and Uses.—Marsh Rosemary is a powerful astringent, and in some sections of the country is very much used in diseases of the bowels, in the form of infusion or decoction. It has proved efficacious in diarrhea, dysentery, etc., in which diseases it is only suited to the latter stages, where a tonic and astringent action is required. The infu- sion, employed as a gargle in affections of the throat, scarlatina anginosa, and as a wash in aphthous and ulcerated sore-mouth, has been very highly recommended. Externally, the powdered root may be applied to old ulcers, or made into an ointment, as a soothing application for piles. The decoction is likewise very useful as an injection in chronic gonorrhea, gleet, leucorrhea, prolapsus ani and uteri, and in some ophthalmic affections. It may be used in all cases where astringents are indicated. The Statice Limonium, of Europe, is possessed of the same powers, but in a less degree. The infusion may be given in doses of from half a fluidounce to two fluidounces, every two, three, or four hours. STELLARIA MEDIA. Chickweed. Nat. Ord.—Caryophyllaceas. Sex. Syst.—Decandria Trigynia. THE plant. Description.—This plant is the Alsine Media of Linnaeus ; it is an annual or biennial weed, from six to fifteen inches in length, with prostrate, branched, brittle, round, jointed, and leafy stems, distinguished by the alternate, lateral, hairy lines, extending from joint to joint. The leaves are ovate, ovate-cordate, and glabrous, the lower on hairy petioles. The flowers are small and white, in forked cymes ; petals two-parted, shorter than the calyx. Stamens varying, three, five, or ten. History. — This is a common plant throughout the United States, growing in fields and around dwellings, in moist, shady places, probably 910 Materia Medica. introduced from Europe ; it flowers from the beginning of spring to the end of autumn. The seeds are eaten by poultry and birds. The whole herb is used, when recent. Properties and Uses.—Chickweed appears to be a cooling demulcent. I have seen the fresh leaves bruised and applied as a poultice to indo- lent, intractable ulcers on the leg, of many years standing, with the most decided and immediately beneficial results ; to be changed two or three times a day. In acute ophthalmia, the bruised leaves will likewise be found a valuable application. An ointment made by bruising the recent leaves in fresh lard, may be used as a cooling application to erysipela- tous and other forms of ulceration, as well as in many forms of cutaneous disease. STILLINGIA SYLVATICA. Queen's Root. Nat. Ord.—Euphorbiaceae. Sex. Syst.—Moncecia Monadelphia. THE ROOT. Description.—This plant is also known by the name of Queen's De- light, Yaw-root, and Silver-leaf; it is an indigenous perennial, with herbaceous stems two or three feet high. The leaves are alternate, sessile, oblong or lanceolate-oblong, obtuse, serrulate, tapering at the base, and accompanied with stipules. The male and female flowers are distinct upon the same plant; they are yellow, and arranged in the form of a spike, of which the upper part is occupied by the male, and the lower by the female flowers. The male florets are scarcely longer than the bracteal scales. History.—This plant is found growing in pine-barrens and sandy soils from Virginia to Florida, and in Mississippi and Louisiana, flowering from April to July. When wounded, the plant emits a milky juice. The root, which is the officinal portion, is large, thick, and woody, in long cylindrical pieces, from one-third of an inch to more than an inch thick, wrinkled when dried, externally of a dirty yellowish-brown color, and exhibiting, when cut across, an interior soft, yellowish, ligneous portion, surrounded by a pinkish-colored bark. It has a slight, peculiar, some- what oleaginous odor, which is strong and acrimonious in the recent root, and the taste is bitterish and pungent, leaving an impression of disagreeable acrimony in the mouth and fauces. It imparts its virtues to water or alcohol, and deteriorates in activity by age. Its properties appear to be owing to a very acrid oil. It also contains resin, woody fiber, coloring matter, extractive, etc. The Oil of Stillingia, so called by its manufacturers, is more properly an alcoholic fluid extract; it is composed of about forty per cent, of oil, with the remainder consisting of extractive, resin, etc. It is prepared Stillingia Sylvatica. 911 by adding alcohol 95 per cent, to the recent root of Stillhjgia, and makino- a saturated tincture; then distil off the alcohol. The residue is the preparation sold and used as the oil of Stillingia. Upon standing for a length of time, a flocculent deposit takes place, of a reddish-brown character. A similar preparation is made with ether by displacement and evaporation; it forms a more consistent liquid, probably holding more fixed oil. The above oil or alcoholic fluid extract of Stillingia, is of a dark brownish-red color, of a strong, peculiar, not unpleasant odor, and of a faint taste at first, but in a short time followed by exceeding pungency and acridity, very persistent in its character, and which is especially felt in the throat and fauces, being accompanied with a very unpleasant sensation in the stomach, if swallowed. The recent root affords a larger quantity of oil, than when old, probably, because the oil becomes oxidized and changed to resin by age, and is no longer soluble in ether, although the real active principle of the article is but little im- paired. I have seen a preparation, called Stillingin, purporting to have been prepared by the Franklin Pharmaceutical Institute of the City of New York, sold for one dollar per ounce. It was, undoubtedly, the above oil, triturated with sugar or sugar of milk, and the whole cost of which would not exceed twenty cents. Properties and Uses.—Stillingia in large doses is emetic and cathartic, producing in many instances, a peculiar, disagreeable burning sensation in the stomach, or some portion of the alimentary canal, accompanied with more or less prostration of the system. In small doses it is an alterative, exerting an influence over all the secretions which is unsur- passed by any other known alteratives. It is an Eclectic remedy of much importance and value, and is extensively used in all the various forms of primary and secondary syphilitic affections, in which it appears to have almost a specific action, also in scrofulous, hepatic, and cutaneous diseases, in which its administration is followed by the most successful results. In the form of fluid extract, combined with oils of anise or caraway it has been found very beneficial in chronic laryngeal and bron- chial affections, and in leucorrhea. Small pieces of the recent root, chewed occasionally through the day, have effectually and permanently cured laryngitis and bronchitis. The oil is entirely too acrid for internal use, unless it be well incorporated with some mucilaginous or saccharine substance; and, for internal use, the fluid extract, or syrup, will be found sufficiently energetic and efficacious. But as an external stimu- lating application, the oil will be found Arery valuable in many instances. One drop of it placed upon the tongue, and repeated three or four times a day, is reputed to have proved successful in cases of severe croup. The dried root is inert or nearly so, hence,, its powder is of no utility Dose of the tincture, from half a fluidrachm to a fluidrachm ; of the decoction, one or two fluidounces. This article is reputed to have formed an ingredient of Swaim's Panacea ; such is not the case. 912 Materia Medica. Off.

STRYCHNOS NUX VOMICA. Nux Vomica. Nat. Ord. — Apocynaceas. Sex. Syst. — Pentandria Monogynia. THE SEEDS. Description. — This is a middle-sized tree, with a short, crooked, thickish trunk, irregularly branched, and covered with a smooth, ash- colored bark; the young shoots are deep green, and highly polished. The wood is white, hard, close-grained, and bitter. The leaves are opposite, on short petioles, oval, shining, smooth on both sides, entire, from an inch and a half to four inches in length, from one to three inches broad, and from three to five-nerved. The flowers are small, greenish- white, funnel-shaped, and are collected into small terminal cymes, with a disagreeable odor. The calyx is five-toothed ; the corolla is also five- parted. Filaments scarcely any or exceedingly short, inserted over the bottom of the divisions of the corolla; anthers oblong, half within the tube, and half without. The ovary is superior, roundish, two-celled, with many ovules in each cell, attached to the thickened center of the partition. Style as long as the tube of the corolla ; stigma capitate. The fruit is a berry, round, about the size of a large apple, and covered with a smooth, hard rind, of a rich orange color when ripe, and filled with a white, soft, gelatinous pulp, in which are five seeds ; these are flat, round, with a prominence in the center, of a grayish color externally and covered with a woolly substance, but internally hard and tough like horn. History.—The Nux Vomica tree is a native of the East Indies, abound- ing particularly on the Malabar and Coromandel coasts. The wood is exceedingly bitter, especially that of the root, which is said to cure inter- mittent fevers, and the bites of venomous snakes. The pulp of the fruit is greedily eaten by various birds. The Lignum Colubrinum or Snake-wood, which is generally referred to the Strychnos Colubrina, is frequently nothing else than the nux-vomica wood. The bark contains a large proportion of brucia, and some strychnia, and is said to be iden- tical with the False Angustura Bark. The officinal part of the plant is the seeds. Nux Vomica seeds are circular, about nine lines in diameter, and two in thickness, flat and slightly concave on one side and convex on the other, umbilicated at one surface, and everywhere beset with fine short ash-colored, or yellowish-gray satiny hairs, attached to a thin, fragile coating, which closely invests the kernel. This internal nucleus or ker- nel is whitish and translucent, occasionally dark-colored and opake, Strychnos Nux Vomica. 913 almost horny, exceedingly tough, very difficult to pulverize, and of an intensely bitter taste. To powder them, the method recommended is to soften them well with steam, then slice them, and dry them ; after which they are ground to powder. The powder has a grayish-yellow color, a faint, sweet odor, and an intense, durable, bitter taste. Water or proof spirit dissolves its active ingredients, but rectified,alcohol acts Avith the most energy. Ether takes up a concrete oil and some wax. Nitric acid renders the powder orange-red. The aqueous decoction is of a pale grayish-yellow color, and intensely bitter, and becomes orange-yellow on the addition of nitric acid, and emerald-green by sesquioxide of iron. Nux Vomica consists of strychnia, and brucia, united with a peculiar acid named Igasuric Acid, concrete oil, wax, yellow coloring matter, soluble gum, starch, and lignin. Strychnia was discovered in 1818 by Pelletier and Caventou, who found it in greater proportion in the bean of St. Ignatius than in the nux vomica. For an account of its prepara- tion and properties, as well as of Brucia, see article Strychnia, in the second part of this work. Properties and Uses.—Nux Vomica is a powerful poison, exerting its influence principally on the cerebral system. In poisonous doses it pro- duces violent tetanic convulsions without impairing the functions of the brain, asphyxia and death. When given in doses sufficiently large to influence the system, a sensation of weight and weakness is experienced, with tremblings in the limbs, and some rigidity on attempting motion. Sometimes there are sudden starts or shocks, more or less frequent and violent, Avith a tendency to permanent inAroluntary contraction or rigid- ity of the muscles. Even in small doses, it will occasionally create a sense of heat in the stomach, constriction of the throat, chest, and abdo- men, and retention of urine; sometimes vertigo, pain in the head, con- tracted pupil, and dimness of vision are produced ; and, more especially with the corpulent and apoplectic, there will be formication, and tingling upon the surface, with more or less perspiration, slight involuntary spasms of the muscles, and a very disagreeable, dreamy or vague con- dition of the brain. The pulse may or may not be increased in fre- quency. Chloroform is said to be beneficial in poisoning by nux-vomica. In small doses it is tonic, and increases the action of the various excretory organs. Nux Vomica is employed principally in the treatment of paralysis, especially when it is of some standing, and where no hyperoemic or hemorrhagic condition of the nervous centers exist; it is generally inap- plicable to the recent forms, until the removal of the primary affection by antiphlogistic means. Its use is limited to cases in which inflam- matory action or congestion has been removed. It is said to be more beneficial in general palsy and paraplegia than in hemiplegia, and has also been found of benefit in local palsies, as of the bladder, likewise in amaurosis, spermatorrhea and impotence. It has also been beneficially 58 914 Materia Medica. employed in neuralgia, chorea, and obstinate constipation. A small quantity added to cathartics, increases their energy. Dysmenorrhea, dyspepsia, dysentery, rheumatism, hysteria, mania, worms, intermittent fever, eneuresis, chronic splenitis, etc., have been successfully treated by the use of this agent. Nux vomica and its alkaloids should always be given Avith great care, the physician closely observing its effects. The dose of powdered nux vomica is five grains three or four times a day, and gradually increased to ten, or until its effects are experienced. The alcoholic extract is the best form of administration and may be given in doses of from one-fifteenth to one-twentieth of a grain as a tonic; and in paralytic affections from half a grain to two grains in the form of pill, and, as with the powder, gradually increased. The saturated tincture may be given in doses of from five to thirty drops, likewise gradually increased. Off.

Description. — This is a tree from fifteen to twenty-five feet in hight, Avith irregular, round branches which are tomentose when young. The leaves are alternate, petiolate, entire, elliptical, deciduous, somewhat pointed, bright-green and smooth above, whitish with soft down beneath, and about two inches in length, by one and a half in breadth. The flowers are white, and in clusters of three or four, at the ends of the young lateral shoots, with angular pedicels. The calyx is hoary, almost hemispherical, rather angular at the base, with five or seven very short marginal teeth; corolla white, externally downy, someAvhat funnel- shaped, and divided into from five to seven deep, elliptical, bbtuse, spreading segments. The stamens are ten, placed in a ring; the flla- ments subulate, and inserted into the corolla, with yellow, erect, oblong anthers. The ovary is ovate, with a slender style and simple stigma. The fruit is a downy drupe of a globose form, containing one or two angular nuts, which are concave on one side and convex on the other. History. — Storax is a native of Syria, Arabia, and other parts of the Levant, and has been naturalized in some of the Southern parts of Europe. The European tree does not yield any of the balsam, which has led some botanists to doubt whether the officinal storax is obtained from it at all. The mode of collecting it in Syria, whether by incisions or by decoction, is not positively known, as the natives make a mystery of their proceedings. There are several kinds of storax in commerce ; Styrax Officinale. 915 the purest is the storax in grains, which are about the size of a pea, opake, soft, adhesive, capable of uniting so as to form a mass, and of a whitish, yellowish-white, or reddish-white color. Another variety, in dry and brittle, amygdaloidal masses, formed of yellowish agglutinated tears, with a brown or reddish matter between them, and wrapped in the leaves of a kind of reed, is called storax amygdaloide. Both of the above varieties are free from impurities, and have a pleasant vanilla odor; they are rarely seen in our markets. The common storax of the shops occurs in brittle, brown or reddish-brown masses, several pounds in weight, of various shapes, somewhat tenacious, and softening under the teeth; it has an agreeable odor like vanilla or balsam of Peru, and apparently consists of sawdust cemented by a balsamic or resinous sub- stance. When exposed to the air it acquires upon its surface, a whitish efflorescent film of benzoic acid. The cakes or masses may be easily crushed to a coarse powder, in which state it is usually sold in the shops. When good, it yields a brown resinous fluid, with the odor of storax, when compressed between hot plates. In consequence of its impurities, it should be purified by solution in alcohol, strained and then the alcohol distilled off by moderate heat, until the storax acquires the proper con- sistence. The storax of commerce consists of a trace of volatile oil, a little gum, some extractive matter, much woody fiber, with from 33 to 54 per cent, of resin, and from 1 to 2.6 per cent, of benzoic acid. Liquid Storax is another variety, and which is the most commonly employed; it is a semifluid adhesive substance, of a slightly greenish- gray color, the surface of which becomes brown or blackish upon expo- sure to the atmosphere, and of an odor somewhat similar to balsam of Peru, but less agreeable. Its source is not accurately known. Landerer says that liquid storax is obtained from a plant growing in the islands and on the mainland of Greece, which is inodorous, and yields no balsam, except that inhabiting the islands of Cos and Rhodes, which in the flowering season exhales a rich vanilla odor, and yields liquid storax from its bark and young twigs. These are formed into balls, and are subjected to pressure in a heated press, when a gray oily matter is obtained, which is exported pure, or made into cakes with finely pow- dered olibanum. Storax has an aromatic and fragrant odor and taste, and yields its active properties to alcohol or ether; water becomes yellow and milky with it, acquiring its odor. A moderate heat fuses it, and a higher temperature inflames it, burning with a white flame, and leaving a light spongy carbonaceous residue. Four hundred and eighty grains of the commercial article, haAre yielded three hundred and sixty of alcoholic extract. As it yields benzoic or cinnamic acid by distillation, it ranks as a balsam. Properties and Uses. — Storax is a stimulant, acting more especially upon mucous tissues, as do nearly all balsams. It has been found bene- 916 Materia Medica. ficial as an expectorant in cough, chronic catarrh, asthma, bronchitis, and other pulmonary affections; also in gonorrhea, leucorrhea, and gleet, in which it is as effectual and more pleasant than copaiba. Com- bined with tallow or lard, it forms a valuable application in many forms of cutaneous disease, especially those common to children, as ringworm, tinea, ringworm of the scalp, etc. It is much used, on account of its fragrance, for compounding ointments and pills, and is an excellent addition to opium in the form of pill, when it is necessary to conceal the taste and smell of this narcotic ; three or four grains of storax may be combined with one grain of opium for this purpose. The dose of storax is from ten to twenty grains, gradually increased. SUCCINUM. Amber. History.—The origin of Amber is very uncertain; it is believed to be a fossil resin, the produce of an extinct plant. It may be derived from some resin formerly liquid or soft; or possibly from the slow oxidation of a fatty matter, as we see succinic acid formed from fats by oxidation. It is found chiefly in Prussia, either on the sea-shore or in the alluvial formations along the coast; it is likewise found in Sicily, and in this country in New Jersey and Maryland. It is a brittle solid, generally in small irregular masses, permanent in the air, having a homogeneous texture and vitreous fracture, and susceptible of a fine polish. Its color is either light or deep yellow, and occasionally reddish, or even deep brown. It has no taste, and is inodorous, unless heated, when it exhales a peculiar, aromatic, not unpleasant smell. It is usually translucent, though occasionally transparent or opake, and is found chiefly associated with lignite, sometimes iron pyrites, and frequently contains insects and fragments of vegetables imbedded in it. By friction it becomes nega- tively electric. Its specific gravity is 1.07. It is for the most part insoluble in all menstrua. Heated in the open air it softens ; at 548° it melts, swells, and burns with a yellow flame, leaving a small portion of ashes. Subjected to distillation in a retort furnished with a tubulated receiver, it yields first a yelloAv acid liquor, which is a solution of impure succinic acid; and aftenvard a thin yellowish oil, Avith a yellow waxy substance, which is deposited in the neck of the retort and the upper part of the receiver. The oil obtained is called the Oil of Amber, Oleum Succini. The waxy matter, exhausted by cold ether of the portion solu- ble in that menstruum, is reduced to a yellow micaceous substance iden- tical with Chrysene, and from which a white crystalline body may be separated by boiling alcohol, identical with the solid carbo-hydrogen Idrialine, and called by its discoverers Succisterene. Both have the same composition, and color sulphuric acid intensely blue, forming a coupled acid. Chrysene is insoluble in most liquids, melts at 455° and Sulphur. 917 is likewise a carbo-hydrogen. As the distillation of amber proceeds, a large quantity of combustible gas is given off, which must be allowed to escape from the tubulure of the receiver. As the heat continues, the oil gradually deepens in color, until it finally becomes black and of the consistence of pitch. Amber repeatedly distilled from nitric acid, yields an acid liquor, from which, after it has been neutralized by caustic potassa, ether separates pure camphor. Camphor may likewise be obtained by distilling to dryness powdered amber with an extremely con- centrated solution of caustic potassa. When the acid crystals form, when amber is subjected to distillation, they may be obtained by com- pressing them in bibulous paper, and subliming them a second time; these crystals of succinic acid were formerly called Salt of Amber, and were much esteemed as a diuretic. Amber consists of a small quantity of fragrant volatile oil; a yellow resin, intimately united with a volatile oil, very soluble in alcohol, ether, or the alkalies, easily fusible, and resembling ordinary resins; another resin, also combined with volatile oil, soluble in ether or the alkalies, sparingly soluble in cold, but more soluble in boiling alcohol; succinic acid; a bituminous principle, having some analogy to the lac-resin of John, insoluble in alcohol, ether, or the alkalies, and constituting more than four-fifths of the amber; also a strongly odorous, bright-yellow substance, which hardens by time. Its elementary composition is, car- bon 80.59, hydrogen 7.31, oxygen 6.73, ashes (silica, lime, and alu- mina) 3.27=97.90. Properties and Uses.—Amber is not used as a medicine in the present day, being employed only in pharmacy and the arts. It is used to prepare succinic acid and oil of amber. In the arts it is made into ornaments, and prepared in making varnishes, for which latter purpose it is first sub- jected to the process of roasting, whereby it is rendered soluble in a mixture of linseed oil and oil of turpentine, forming amber-varnish.

History. — Sulphur is an abundant natural production, occurring principally in volcanic districts, especially in Sicily, where it may be obtained in a state of purity, and often crystallized. It is also very gene- rally disseminated throughout the mineral kingdom in combination with gypsum, heavy-spar, and many other minerals, with oxygen as sulphuric 918 Materia Medica. acid, with hydrogen as sulphureted hydrogen, with mineral waters, and with the metals, especially lead, iron, copper, quicksilver, etc., form- ing with them compounds called sulphurets or sulphides. It is almost always present in minute quantity in animal and vegetable matter, especially in mustard and other cruciform plants; indeed it is an essen- tial ingredient of vegetable and animal fibrine, albumen, and caseine, and as such is indispensable to vegetation and to animal life. When found in a native state, it is in masses, translucent or opake, or in the powdery form, mixed with various earthy impurities. For supplying the wants of medicine and the arts, sulphur is obtained from two sources; one, imported from Sicily, and known as Native or Volcanic Sulphur, the other, prepared from the sulphurets of iron or copper, and known as Pyritic Sulphur, which is seldom employed in medicine. Volcanic sulphur occurs in masses or crystals; the crystal- lized variety presents the form of very acute rhombic octaedres, bright sulphur-yellow in color, and exceedingly pure. The massive sulphur, has a grayish-yellow tint, rather less brittle and less lustrous than the preceding, with many grayish or bluish spots or streaks, arising from mineral impurities. From the volcanic sulphur, pure sulphur is pre- pared by distillation. Crude sulphur is prepared by distillation of sul- phur from the sulphur earths; this, when purified by being again melted, allowing the impurities to settle, and then pouring the purer sulphur into cylindrical molds about an inch in diameter, forms the Roll Sulphur or Cane Brimstone of commerce ; and the residue of this process, ground to powder, being a very impure sulphur, of a gray color, is known by the name of Sulphur Vivum or Horse Brimstone. Roll sulphur is now made by subliming the sulphur in iron vessels, fusing the product, and casting it into cylindrical molds. The best mode of purification is to sublime the sulphur, pass the sub- limed vapor into a close chamber of considerable size, where it condenses in fine impalpable powder, consisting of minute globules between a thirtieth and a two-hundredth of an inch in diameter, unless they have been exposed to light or agitation, when they are apt to present a crys- talline structure. This is called Flowers of Sulphur or Sublimed Sul- phur. Washed Sulphur is the sublimed sulphur thoroughly washed with water to free it from the acidity which is apt to be present, in con- sequence of the combustion some of it undergoes in the act of subliming, thereby giving rise to sulphuric acid. When properly washed, it under- goes no change by exposure to the atmosphere. Crude sulphur is imported to this country principally from Sicily and the ports of Italy. Roll sulphur and the flowers of sulphur generally come from Marseilles. Sulphur is an elementary, non-metallic, brittle solid, of a pale-yellow color, permanent in the air, and exhibiting a crystalline texture and shining fracture, with a perceptible smell when rubbed, and a faint peculiar taste. It is a bad conductor of heat, and Sulphur. 919 becomes negatively electric by friction. When pure its specific gravity is 1.99; when impure it may be as high as 2.35. Its equivalent number is 16, and its symbol S. It is insoluble in water, but soluble in petro- leum, alkaline solutions, the fixed and volatile oils, and when finely powdered in alcohol or ether. It begins to volatilize at about 180°, giving off its peculiar odor, and when heated to between 224° and 230°, it passes into a state of fusion ; about 400°, or a little higher, the melted mass becomes thicker and brownish; and if kept for some time at this temperature, or suddenly cooled by being poured into cold water, it forms for a short while aftervvard a soft, tough mass, called Amorphous Soft Sulphur, which is capable of receiving and retaining delicate im- pressions of seals, coins, and the like. At 650° it sublimes unchanged, if oxygen be excluded; in open vessels, sulphur, when inflamed, burns with a lambent blue flame, combining with the oxygen of the air, and giving rise to highly suffocating vapors of sulphurous acid gas. As a chemical, sulphur is exceedingly important, its combinations being numerous, and among the most powerful agents of chemistry. Sulphur, from carelessness in its purification, may contain sulphuric acid, from which it should always be freed; this may be detected by agitating some of the sulphur in water, and testing the water with litmus paper. It is sometimes adulterated with arsenic, which may be detected by converting the sulphur and arsenic into sulphuric and arsenic acids, through the action of nitric acid and heat, neutralizing the acids by car- bonate of soda, adding muriatic acid in excess, and transmitting sulphu- reted hydrogen for some minutes; upon which yellow sulphuret of arsenic will fall down. Properties and Uses.—Sulphur is a stimulant, laxative, diaphoretic, alterative, and in regard to scabies, it is considered a specific. It is used in hemorrhoids, diseases of the bladder, and in pregnancy, as a mild cathartic, either alone, combined with cream of tartar, or with some other saline purgative. It is given alone in one or two drachm doses, in milk or molasses; or thirty grains of sulphur combined with two drachms of bitartrate of potassa. One serious objection to its use is, that it renders the stools, and even the insensible transpiration, insup- portably fetid; which arises from its being converted within the body into sulphureted hydrogen; if the sulphur contains acid, its operation will be attended with more or less griping. The soda of the bile is sup- posed to render the sulphur soluble. In chronic catarrh, chronic rheu- matism, cutaneous diseases, and in the chronic stage of pertussis, it may be administered two or three times a day, in doses of twenty or thirty grains. Externally, sulphur is used in various cutaneous diseases of the vesi- cular, scaly, or papular kind. Sulphur-baths are likewise found bene- ficial in scrofula, chronic palsy, chronic rheumatism, scabies, and all kinds of scaly cutaneous disorders; the sulphurous acid gas is applied 920 Materia Medica. to the body, the head being protected. The effects occasioned are warmth, redness, and pricking of the integuments, followed by consid- erable sweating and excitement of the circulation. If the gas should be inhaled, it will prove powerfully irritating to the glottis, and altogether irrespirable, even when diluted Avith atmospheric air. The effects of sul- phur, and of sulphurous acid in cutaneous diseases and rheumatism may be obtained by using the sulphuret of potassa in the form of bath, say two or three ounces to one hundred pounds of water.

Description. — Comfrey has an oblong, fleshy, perennial root, black externally, and a pilose, herbaceous stem, three or four feet high, branch- ing above, and winged by the decurrent bases of the pointed, Avavy, rough-edged leaves; the lower leaves and radical are ovate-lanceolate, tapering into a petiole ; the upper and floral lanceolate. The flowers are white or of a rose color, and disposed in terminal, revolute racemes. The calyx is five-parted, with lanceolate, acuminate sepals; the corolla tubular-campanulate; limb with five recurved teeth. Stamens five, included; anthers elongated. Style filiform. Nutlets smooth, ovate, fixed by a large excavated (perforate) base. The whole plant is rough with dense hairs. History.—This is a European plant,.much cultivated in our gardens for medical uses, and flowering through the summer. The root is the officinal part; it is spindle-shaped, branched, sometimes more than an inch thick and a foot long, externally smooth and blackish, internally white, fleshy, and juicy, containing much mucilage. When dried it becomes wrinkled, of a firm, horny consistence, and of a dark color within. It is nearly inodorous, and has a mucilaginous, feebly astrin- gent taste. It contains a small quantity of tannin, and a great abundance of mucilage, which it yields to water. Properties and Uses.—This plant is demulcent and slightly astringent. With other mucilaginous agents, it is considered inert or of but little medical importance by many writers; but this is an erroneous view, the result of deficient investigation. All mucilaginous agents exert an influ- ence on mucous tissues, hence the cure of many pulmonary and other affections, in which these tissues have been chiefly implicated, by their Symplocarpus Fcetidus. 921 internal use. Physicians must not expect a serous disease to yield to remedies which act on mucous membranes only ; and to determine the true value of a medical agent, they must first ascertain the true charac- ter of the affection, as Avell as of the tissues involved. Again, mucila- ginous agents are always beneficial in scrofulous and anaemic habits. Comfrey root is very useful in diarrhea, dysentery, coughs, hemoptysis, other pulmonary affections, leucorrhea, and female debility ; these being principally mucous affections. It may be boiled in water, wine, or made into a syrup, and taken in doses of from one to four fluidounces of the preparation, two or three times a day. Externally, the fresh root, bruised, forms an excellent application to bruises, ruptures, fresh wounds, sore breasts, ulcers, white swellings, etc. Off.

Nuttall calls it Symplocarpus, which is adopted by many botanists, and which we deem it best to retain. It is a very curious plant, having a large, abrupt, perennial root or tuber, with numerous verticillate, fleshy fibers, which penetrate to the depth of two or more feet. The spathe appears before the leaves, and is ovoid, roundish, cucullate, turgid, various in width, spotted and sometimes nearly covered with brownish-purple blotches, varied with red, yellow, and green, the top acuminate and incurved, the edges folded inward, auriculate at base, and at length coalescing. Within the spathe, the flowers, which resemble it in color, are placed in great numbers upon a globose, pedunculate, simple spadix, for which they form a compact covering. The flowers are tesselately imbricate, adnate. The calyx is composed of four fleshy, cuneate, truncate sepals, the top and edges inflected, at length becoming very thick. Corolla none. Sta- mens four, opposite the sepals, with subulate fllaments, equal in length to the calyx, and oblong, exserted, two-celled anthers. The style is four- sided, tapering; stigma minute, pubescent; ovary roundish, concealed within the spadix. After the spathe decays, the spadix continues to grow, and with it every part of the flowers except the anthers. When the fruit is ripe, the spadix has attained many times its original dimen- sions, while the calyx, filaments and style are larger, very prominent and separated from each other. Within the spadix, at the base of each style, 922 Materia Medica. is a naked, round, fleshy seed, as large as a pea, white, tinged with green and purple, invested Avith a separate membranous coat, and with a prominent embryo situated in a depression at top, and umbilicately attached to a large, solid perisperm. Sometime after the flowers, numer- ous, large, crowded leaves appear, which are oblong, cordate, acute, smooth, with numerous fleshy veins of a pale color, on long, channeled petioles, furnished with large oblong sheaths, bright-green, and often twenty inches long by twelve broad. History.—This is an indigenous plant, growing abundantly in various parts of the United States, in moist situations, flowering in March and April, and maturing its fruit in August. The whole plant, especially when bruised, emits a very disagreeable alliaceous odor, which has given rise to the several names, Skunk-weed, Skunk-cabbage, Polecat-weed, and Meadow-cabbage. The root is the officinal part, and should be col- lected in autumn or early in spring, and dried with care. It has a disa- greeable, fetid odor, and an acrid taste. When properly dried and whole, it is cylindrical, or in the shape of a truncated cone, two or three inches long, by about an inch in thickness, dark-brown externally, and very rough from the insertion of radicles, internally white and amyla- ceous. When in transverse slices, they are of various lengths, about as thick as a quill, very much flattened and Avrinkled, Avhite within, and coArered by a yelloAvish reddish-brown epidermis, considerably lighter colored than the body of the root. Drying lessens the odor, as well as the acrimony of the plant, and age and exposure dissipate them entirely, consequently the root should be renewed annually. The seeds are fre- quently used and preferred, as being more energetic than the root; they have an exceedingly acrid taste, and emit the peculiar odor of the plant, only when bruised. They preserve their virtues longer than the root. The properties of this plant chiefly depend upon a volatile principle, which is materially diminished by drying, and is entirely dissipated by heat. Alcohol or water extracts its virtues, and the aqueous infusion should be made by displacement. The roots and seeds contain volatile fatty matter, volatile oil, fixed oil, of which the seeds yield twenty per cent., starch, etc. Properties and Uses.—In large doses, Skunk-cabbage will occasion nausea, vomiting, headache, vertigo, and dimness of sight. In medici- nal doses, it is stimulant, antispasmodic, expectorant, and slightly narcotic. It has been successfully used in asthma, hooping-cough, nervous irritability, hysteria, epilepsy, and convulsions attending preg- nancy and parturition; likewise in chronic catarrh, pulmonary, and bronchial affections. The powdered root or seed may be given in doses of from ten to forty grains, three times a day ; but the most eligible mode of administration is a saturated tincture of the fresh root, of which one or two fluidrachms may be given for a dose.

Description. — This is a large tree, with numerous spreading branches, and an erect, thick trunk, covered with a rough, ash-colored bark. The leaves are alternate and pinnate, consisting of many pairs of opposite leaflets, which are subsessile, entire, obtuse, elliptic-oblong, unequal at the base, about six lines long by two broad, smooth on both sides, and of a yellowish-green color ; the petioles are from four to six inches long, and channeled; stipules small, deciduous. The leaflets close in the evening, or in cold, moist weather, like those of the sensitive plant. The flowers are in simple, lateral and terminal racemes; the calyx is four- leaved, cruciate, expanding, deciduous, somewhat tubular at base, bila- biate, the upper-lip tri-partite, the lower broad, two-toothed. The corolla is somewhat papilionaceous, erect, unilateral, the length of the calyx. The vexillum or middle petal is oblong, its margins involute and curled; wings oval, margins curled; all three are beautifully variegated with red and yellow; Keel two short subulate processes under the stamens. The stamens are ten, of which seven are very short and sterile, and three long, purplish, curved, united at base, bearing large, ovate, incumbent anthers. The ovary is oblong, compressed, incurved, and supports a subulate style with an obtuse stigma. The legume is oblong, compressed, one-celled, two to twelve seeded, filled with a firm, acid pulp, covered with a hard, scabrous bark, which never separates into valves; under the bark run three fibers, one down the upper concave margin, and the other two at equal distances from the inferior or convex edge. Seeds from six to twelve, somewhat trapeziform, compressed, covered with a smooth, hard, brown shell, and inserted into the convex side of the pericarp. History.—The Tamarind tree grows in the East and West Indies, Egypt and Arabia. The fruit is the officinal portion ; in the recent state they have an agreeable, sour taste, without any mixture of sweetness. As usually obtained, they are in the preserved state, made by placing the pods previously deprived of their shell, in layers in a cask, and then pouring boiling syrup over them ; thus prepared, they form a dark- colored adhesive mass, consisting of syrup mixed with the pulp, mem- branes, strings and seeds of the pod, and of a sweet acidulous taste. 924 Materia Medica. The seeds should be hard, clean, and not swollen, the strings tough and entire, and the odor without mustiness. The presence of copper may be ascertained by the reddish coat imparted to the blade of a knife which has been immersed in the tamarinds. According to an old analysis by Vauquelin, they contain a little sugar, pectic acid, and parenchymatous fiber, with 9.4 per cent, of citric acid, 1.5 of tartaric acid, 0.5 of malic acid, and 3.25 of bitartrate of potassa. It readily parts with its proper- ties to water. Properties and Uses.—Tamarinds are laxative and refrigerant, and infused in water form a grateful drink in febrile diseases. During con- valescence, the addition of the pulp to the patient's diet, is not only agreeable, but tends to keep the bowels in a soluble condition. A con- venient cooling laxative is Tamarind-whey, made by boiling an ounce of the pulp in a pint of milk, and straining the product. Combined with senna, or resinous cathartics it is said to weaken their purgative power. Dose, from a drachm to two ounces. TANACETUM VULGARE. Tansy. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Superflua. THE HERB. Description.—Tansy has a perennial, moderately creeping root, and an erect, herbaceous, obscurely hexagonal, leafy, solid, striated, smooth stem,, two or three feet in hight, and branched above into a handsome corymb of flowers. The leaves are smoothish, dark-green, doubly and deeply pinnatifid; the segments are oblong-lanceolate, pinnatifid and incisely serrate ; the margined petiole cut-toothed. The flowers are golden yellow, and arranged in dense, terminal, many-headed, fastigiate corymbs ; each flower is composed of numerous florets, of which those constituting the disk are perfect and five-cleft, those of the terete rays, very few, pistillate, and trifid. Scales of the involucre scarious at the apex, small, obtuse, imbricated. The pappus short, equal, membranous, five-lobed; achenia with a quadrangular entire crown. There is a variety called Double Tansy, Tanacetum Crispum, with crisped and dense leaves. History.—Tansy is a native of Europe, extensively cultivated in the gardens of this country, and likewise found growing wild in the roads and old fields, flowering from July to September. The whole herb is officinal; it has a strong, peculiar, and fragrant odor, but which is dis- agreeable to some, and a warm, aromatic, bitter, and somewhat acrid taste. Its odor is much diminished by drying. It imparts these proper- ties to alcohol, or boiling water in infusion, and which depend on bitter extractive, and a greenish-yellow volatile oil which has the flavor of the Taraxacum Dens-Leonis. 925 plant, is lighter than water, and deposits camphor upon standing. Ac- cording to analysis, the leaves contain volatile oil, in greater proportion than in the seeds, fixed oil, wax or stearin, chlorophylle, yellow resin, yellow-coloring matter, tannic and gallic acids, bitter extractive, in less proportion than in the seeds, gum, lignin, and a peculiar acid called tanacetic, which precipitates lime, baryta, oxides of lead, and copper. Properties and Uses.—Tansy is tonic, emmenagogue and diaphoretic. In small doses, the cold infusion will be found useful in convalescence from exhausting diseases, in dyspepsia with troublesome flatulence, hysteria, jaundice, and worms. A warm infusion is diaphoretic and emmenagogue, and has been found beneficial in intermittent fever, suppressed menstruation, tardy labor-pains, and as a preventive of the paroxysms of gout. The seeds are reputed the most effectual as a vermifuge. The oil is likewise used as an anthelmintic, and as an abor- tive ; but for this last purpose it is highly dangerous. Tansy is much employed in the form of fomentation to swellings and tumors, local inflammations, etc., and applied to the bowels in amenorrhea, and painful dysmenorrhea. The vinous infusion is said to be beneficial in stran- gury, and other urinary obstructions, and in debility of the kidneys. The dose of the powder is from thirty to sixty grains, two or three times a day; of the infusion, from one to four fluidounces; of the tincture, one or two fluidrachms ; of the oil, from two to ten drops.

Description.—This plant is placed in the Natural Order Cichoracece by Lindley, and is the Leonlodon Taraxacum of Linnaeus. It is a herba- ceous plant, with a perennial, fusiform, fleshy, whitish, milky root, covered Avith a brown epidermis. The leaves are radical, sessile, nume- rous, runcinate, toothed, smooth, of a fine green color, and spreading. The scape or flower-stem rises from the midst of the leaves, six inches or more in hight; it is erect, round, naked, smooth, brittle, fistulous, and terminated by a single head of floAvers of a golden-yellow color, which expand in fine weather and in the morning only, and close in the even- ing; the heads are about an inch and a ha]f wide. The involucre is imbricated, oblong, and double; the exterior scales being linear-oblong, appressed, spreading, and reflexed; the inner are in a single series, larger and erect. The florets are numerous, equal, ligulate, truncated, and five-toothed. The stamens have capillary filaments with conjoined anthers. The ovary is obovate, crowned with a slender, cylindrical style, 926 Materia Medica. with two revolute stigmas. The receptacle is convex, naked, and punc- tate. The achenia are solitary, oblong, and supporting a simple, radiated pappus on a long pedicel. After blossoming the inner involucre closes for a time, the slender beak elongates and raises up the pappus while the fruit is forming, the whole involucre is then reflexed, exposing to the wind the naked fruits with the pappus displayed in an open globular head nearly two inches in diameter. History.—This plant grows spontaneously in most parts of the globe, in fields, grass-plats, and along roadsides, flowering from the commence- ment of spring to late in the autumn. There are several species named by Botanists, but which appear to be mere varieties of this one, and which possess the same physical characters. The young leaves are much used as a salad or greens. The whole plant abounds in a milky, bitter juice, whose sensible qualities are said to be greater just before inflorescence. The root is the officinal part, and yields its properties to boiling water; it should be collected in the months of July, August, and September. When recent, it is several inches in length, from a quarter of an inch to three-quarters of an inch thick, round, tapering, some- what branched, brownish, or brownish-yellow externally, whitish inter- nally, with a yellowish ligneous cord running through its center, and abounding in a milky juice. On drying, it loses more than half its weight, and becomes shrunk, wrinkled longitudinally, brittle, with a shining, somewhat resinous fracture. It is inodorous, with a sweetish, herbaceous, mucilaginous, bitter taste. The milky juice has been found on analysis to contain gum, bitter extractive, gluten, caoutchouc, saline matters, a trace of resin, and a free acid; beside which, the root contains starch and saccharine matter. When changed by exposure, mannite has been obtained. M. Pollex has obtained Taraxacin by boiling the milky juice of the root in distilled water, which removes albumen and resin; filter the liquid, concentrate, and allow it to evaporate sponta- neously in a warm place. The taraxacin forms in crystals, and may be purified by repeated solution and crystallization in alcohol or water. It is in stellated and dendritic masses, bitter, and somewhat acrid, neutral, fusible, permanent, very soluble in alcohol, ether, or boiling water, sparingly soluble in cold water. Too long boiling, impairs the virtues of Dandelion root, and which should always be used while recent. Properties and Uses. — Dandelion root when dried exerts but little therapeutic influence upon the system; but in its recent state it is slightly tonic, diuretic, aperient, and alterative. It is supposed to act especially upon the liver, proving effectual in torpor and chronic engorge- ments of that organ, as well as of the spleen. It is also reputed useful in dropsical affections depending on an abnormal condition of the abdo- minal organs, in uterine obstructions, cutaneous affections, and in derange- ments of the hepatic and digestive systems. Its diuretic and aperient Tela Arane^e — Thea Chinensis. 927 effect is augmented by the addition of bitartrate of potassa. As far as my own experience with this article goes, I think its virtues have been overrated. The existence of an irritable condition of the stomach or bowels, or acute inflammation contra-indicate its employment. Dose of the decoction one or two ounces; of the extract from five to thirty grains. Off. Prep. — Decoctum Taraxaci; Extractum Taraxaci; Extractum Taraxaci Fluidum; Pilulae Taraxaci Compositae. TELA ARANE^E. Cobweb. Spidersweb. History. — The medicinal species of spider from which the web is obtained is the Tegeneria Medicinalis of this country, which are found in cellars, barns, and other dark places; they are of a brown or blackish color. The web of the field-spider is said to be of no account, medici- nally, while that of the house-spider is reputed to possess extraordinary virtues. There are various opinions among medical men as to the modus operandi of cobweb, some attributing it entirely to the control of the imagination, while others view it in a different light, and entertain favorable opinions of it as a powerful therapeutical agent. Properties and Uses.—Febrifuge, sedative, and antispasmodic. Said to have been found useful in the cure of intermittents Avhen all other agents have failed; also recommended in various nervous and spasmo- dic diseases, for the purpose of controlling and tranquilizing irregular nervous action, exhilarating the spirits, and disposing to sleep, without any narcotic action on the brain, as in periodical headache, hysteria, asthma, chorea, hectic fever, and nervous irritations attended with mor- bid vigilance and irregular muscular action. Dose, is five or six grains, every three or four hours, in the form of pill. Externally, it is asserted to have been advantageously employed as a styptic in wounds, and a healing application in superficial ulcers. The small silver-headed spider, given in a dough-pill, is said to be a prompt and efficacious cure for ague. THEA CHINENSIS. Tea. Nat. Ord.—Ternstromiaceas. Sex. Syst.—Monadelphia Polyandria. THE LEAVES. Description.—The Tea-plant is a shrub or small tree, which in a state of nature may attain a hight of twenty-five or thirty feet, but which, when cultivated, seldom exceeds six or seven. The leaves are alternate, with short petioles, very smooth, ovate-oblong, somewhat acuminate, 928 Materia Medica. stiff, coriaceous, slightly dentate, green, shining, and marked with one rib and many transverse veins. They are two or three inches long, and from half an inch to an inch broad. The flowers are Avhite, axillary, and single, or supported two or three together on short, glabrous pedun- cles. The calyx is persistent, short, green, with five ovate, rounded, obtuse divisions. The corolla is much larger than the calyx, and con- sists of from four to nine large, unequal, rounded, very concave petals. The stamens are very numerous, rather shorter than the corolla, with subulate white filaments, bearing rounded, reniform, yellow anthers, opening at the sides. The ovary is ovate, downy, surrounded by a fleshy ring at base, three-celled, each cell containing two ovules. The styles are three, free above, with obtuse stigmas. The fruit is a three- celled capsule, each cell containing one, sometimes two seeds. Several species have been named by Botanists, but at present, it is believed that only one has been described, and the others are mere varieties in which there exists a uniformity of character. There may be other species, but it is not positively determined. Either of the varieties described as Thea Bohea, or Thea Viridis, will afford black or green tea according to the mode of manufacture. These varieties differ thus: Thea Viridis. Leaves ellipto-lanceolate, acuminate, emarginate, and undulate; flowers axillary, solitary; this variety furnishes the green tea principally. Thea Bohea. Leaves smaller and flatter, darker-green, coriaceous, terminating gradually in a point, not acuminate or emargin- ate; flowers axillary, aggregated; this affords the black tea. History.—The Tea plant is a native of China and Japan. It is an ever- green shrub from four to eight feet high, and in favorable situations even to thirty feet. It is divided into the green and black teas. The green tea is characterized by a dark-green color, sometimes inclining more or less to blue or brown. It has a peculiar, refreshing, somewhat aromatic odor, and an astringent, slightly pungent, and agreeably bitter- ish taste. Its infusion is of a pale greenish-yellow color, with the taste and odor of the leaves. Green tea contains gallic acid, tannic acid, gum, gluten, lignin, bitter extractive, and volatile matter. Black tea is distin- guished by a dark brown color; usually less firmly rolled and lighter than the green. Its odor is fainter, and of a somewhat different charac- ter, though still fragrant. Its taste is astringent and bitterish; less pungent and less agreeable than the green. It contains tannic acid, gum, gluten, lignin, and volatile matter. Properties and Uses.—Gently excitant, astringent and stimulant, and the finer varieties exert a decided influence over the nervous system, evinced by the feeling of comfort, and even exhilaration which it pro- duces, and the unnatural wakefulness to which it sometimes gives rise. In moderation, the infusion is a grateful and harmless beverage, but long continued, or in excessive quantity, it induces unpleasant, nervous Thuja Occidentalis. 929 and dyspeptic symptoms. Black tea, on this account, is preferable to green. Green tea may be used in diarrhea, in debility after an emetic, cathartic, or sudorific, and as a grateful stimulant and diaphoretic in colds and some fevers. Externally, the infusion has been used with advantage as a collyrium. Off. Prep.—Lotio Hydrastis Composita. THUJA OCCIDENTALIS. Arbor Vitae. Nat. Ord.—Pinaceaa. Sex.

Description.—This tree, also called False White Cedar, from its resem- blance to the white cedar, ( Cupressus Thyoides), is indigenous to this country, and attains the hight of from thirty to fifty feet. The trunk is crooked, rapidly diminishing in size upAvard, throwing out recurved branches from base to summit; the branches ancipital, flat and broad. The wood is very light and soft, but exceedingly durable. The leaves are evergreen, rhomboid-ovate, with a gland on the back, squamose, appressed, imbricated in four rows. Cones terminal, oblong, nodding; scales pointless, one-seeded ; seeds broadly Avinged. History.—This evergreen tree grows wild in various parts of the United States from Canada to Carolina, on the rocky borders of streams and lakes, and in swamps, flowering in May. It abounds especially in Canada and the Northern States; it is said to attain only the hight of thirty-six feet, and fourteen inches diameter when one hundred and fifty years old. The leaves and twigs are the parts used; they have an agreeable bal- samic odor, and a strong, balsamic, camphorous and bitter taste. A yellowish-green volatile oil may be obtained from them by distillation. Water or alcohol extracts their virtues. Properties and Uses.—A decoction of the leaves has been a popular remedy in intermittent fever, remittent fever, rheumatism, cough, scurvy, etc. Made into an ointment Avith lard or other animal fat, the fresh leaves are useful as a local application in rheumatic and neuralgic affec- tions ; a poultice of the cones and powdered Podophyllum in milk, will, it is asserted, remove the Avorst rheumatic pains. The oil has been success- fully employed as a vermifuge. The expressed juice or tincture of the leaves is highly recommended as an application to condylomata, remov- ing these growths in from three to four weeks. The tincture to be made by bruising an ounce of the fresh leaves, and macerating it for several days in half a pint of alcohol. The condylomata should be kept constantly moistened with the tincture by means of lint dipped in it. By some it is said to act as a powerful excitant, others again deny this. 69 930 Materia Medica. THYMUS VULGARIS. Thyme. Nat. Ord.—Lamiaceaa. Sex. Syst.—Didynamia Gymnospermia. THE herb. Description.—Thyme is a small undershrub, with erect, suffruticose, numerous, branched stems, procumbent at base, and from six to ten inches in hight. The leaves are oblong-ovate and lanceolate, numerous, revolute at the sides. The flowers are bluish-purple, small, and in ter- minal, leafy, whorled spikes. The Thymus Serpyllus, Wild Thyme or Mother of Thyme, with a decumbent stem, flat, entire, elliptical, punctate, obtuse, and petiolate leaves, ciliate at base, and purple, spotted, capitate flowers, has similar virtues to the above. History.—These two plants are natives of Europe, introduced into this country, and extensively cultivated in gardens as culinary plants, espe- cially the T. Vulgaris; they blossom during the summer. The whole herb is the part used; it should be collected Avhen in flower, and care- fully dried. It has a strong, aromatic, peculiar, agreeable odor, which is retained when properly dried, and a pungent, aromatic, and camphor- ous taste. Its active properties depend upon a pale-yellow, or greenish volatile oil, (oleum thymi), of specific gravity 0.905, and Avhich may be obtained by distillation with water. In the shops it is frequently met with of a brown color, under the name of " Oil of Origanum." The herb yields its virtues to alcohol or boiling water by infusion. Properties and Uses.—Thyme is tonic, carminative, emmenagogue and antispasmodic. The cold infusion is useful in dyspepsia with weak and irritable stomach, and as a stimulating tonic in convalescence from exhausting diseases. The warm infusion is beneficial in hysteria, dys- menorrhea, flatulence, colic, headache, and to promote perspiration. Occasionally, the leaves have been employed externally, in fomentation. The oil is valuable as a local application to neuralgic and rheumatic pains; and internally, to fulfill any of the indications for which the plant is used. Dose of the infusion from one to three fluidounces ; of the oil, from two to ten drops on sugar, or in emulsion. TRIFOLIUM PRATENSE. Red Clover. Nat. Ord.—Fabaceaa. Sex. Syst—Diadelphia Decandria. the blossoms. Description.—Red Clover is a biennial plant with several stems arising from the same root, ascending, somewhat hairy, and varying much in Trifolium Pratense. 931 its hight. The leaves are ternate; the leaflets oval or obovate, entire, nearly smooth, often notched at the end, and lighter colored in the center. The stipules are ovate, mucronate. The flowers are red, fra- grant, and disposed in short, dense, ovate, sessile spikes or heads. The corollas unequal, monopetalous; the lower tooth of the calyx longer than the four others, which are equal, and all shorter than the rose-red corolla. History.—This plant is common to the United States, being exten- sively cultivated in grass lands, with herds-grass (Phleum Pratense) and other grasses, and often alone; it flowers throughout the summer. The blossoms or flowers are the parts used. A strong decoction is made of them, which is evaporated to the consistence of an extract. Properties and Uses.—The extract spread on linen or soft leather, is said to be an excellent remedy for cancerous ulcers. It is also highly recommended in ill conditioned ulcers of every kind, and deep, ragged- edged, and otherwise badly conditioned burns. It possesses a peculiar soothing property, proves an efficacious detergent, and promotes a health- ful granulation. There are two other varieties of clover which are occasionally em- ployed by practitioners, viz: the Melilotus Officinalis, of Willdenow, or M. Vulgaris, of Eaton,—Yellow Melilot Clover, with an erect, sulcate stem, about three feet high, with spreading branches. The leaves are pinnately trifoliate ; leaflets obovate-oblong, obtuse, smooth, with remote, mucronate teeth. The flowers are yellow, and disposed in one-sided, spicate, axillary, loose, paniculate racemes; calyx half as long as the corolla ; legume ovoid, two-seeded. It is an indigenous annual, growing in alluvial meadows, and flowering in June. The whole plant is scented, having nearly the odor of the sweet-scented vernal grass, Anthoxanthum Odoratum. The other is the Melilotus Leucantha, of Koch, M. Alba, of Nuttall, and Trifolium Officinale, of Linnaeus,—White Melilot Clover, or sweet-scented clover, a biennial, with an erect, robust, Arery branching, sulcate stem, from four to six feet high ; leaflets variable, oval, ovate, ovate-oblong, truncate, and mucronate at the apex, remotely serrate, and one or two inches long; stipules setaceous. The flowers are white, numerous, the racemes more loose and longer than in the preceding species. Petals unequal, banner longer than wings or keel; calyx shorter than the corolla by more than one-half. This plant grows in similar situations with the last, flowering in July and August, and having a sweet fragrance, which is improved upon being dried. The leaves and flowers of these two plants are boiled in lard, and formed into an oint- ment, which is found of utility as an application to all kinds of ulcers. The Vanilla or Seneca Grass, used for a stimulant purpose, is the Hiero- chloa Borealis. 932 Mateiua Medica. TRILLIUM PENDULUM. Bethroot. Nat. Ord.—Trilliaceae. Sex. Syst.—Hexandria Trigynia. THE ROOT. Description.—This is one of an extensive genus of North American, herbaceous, perennial plants, Avhich are variously known under the names of Wake-Robin, Birth-root, Indian Balm, Lamb's Quarter, Ground Lily, etc. It has an oblong, tuberous root, from which arises a slender stem, from ten to fifteen inches in hight. The leaves are three in number, whorled at the top of the stem, suborbicular-rhomboidal, abruptly acu- minate, from three to five inches in diameter, and on petioles about a line in length. The flowers are white, solitary, terminal, cernuous, on a recurved peduncle from an inch to two and a half inches long. The sepals are green, oblong-lanceolate, acuminate, an inch long; the petals are oblong-ovate, acute, and an inch and a quarter in length by half an inch broad. Styles three, erect, with recurved stigmas. History.—This plant is common to the Middle and Western States, growing in rich soils, in damp, rocky, and shady woods, and flowering in May and June. Nearly all the species of the genus Trillium, are medi- cinal, and possess analogous properties ; and among them the T Erythro- carpum, T. Grandiflorum, T. Sessile, T. Eredum and T. Nivale, are the most common, and consequently the most frequently collected and em- ployed. These plants may generally be known by their three verticillate, net-veined leaves, and their solitary, terminal flower, which varies in color in the different species, being white, red, purple, Avhitish-yellow, or reddish-white ; the peduncle Avill also be found erect in some species, and recurved in others. The roots of these plants are oblong or terete, somewhat tuberous, dark or brownish externally, white internally, from one to five inches in length, and from half an inch to an inch and a half in diameter, beset with a few branching fibers laterally. They have a faint, slightly terebinthinate odor, and a peculiar aromatic and sweetish taste ; when chewed they impart an acrid astringent impression in the mouth, causing a flow of saliva, and a sensation of heat in the throat and fauces. The root is said to contain volatile oil, gum, resin, extrac- tive, tannic acid, and fecula. It yields its active properties to water, and its tonic and stimulant virtues to diluted alcohol. Properties and Uses.—Bethroot is astringent, tonic, and antiseptic; it has been employed successfully in hemoptysis, hematuria, menorrhagia, uterine hemorrhage, leucorrhea, cough, asthma, and difficult breathing, and is said to have been much used by the Indian women to promote parturition. The most astringent are used in hemorrhages ; the most acrid in asthma, hectic fever, and catarrhal cough; and all are service- able in leucorrhea, and morbid discharges from mucous tissues. Boiled Triosteum Perfoliatum. 933 in milk, it has been administered with benefit in diarrhea and dysentery; and an infusion of equal parts of Trillium and Lycopus Virginicus, has been highly recommended for the cure of diabetes. Externally, the root made into a poultice, is very useful in tumors, indolent or offensive ulcers, carbuncles, bubos, stings of insects, and to restrain gangrene. In some instances its efficacy has been increased by combination with bloodroot. Mr. W. S. Merrell states that the red bethroots will check ordinary epistaxis, by merely smelling the freshly exposed surface of the recent root, and he supposes therefore that they contain an astringent principle of a volatile nature. The leaves of the beth-plants, boiled in lard have been much used, in some sections of country, as an application to ulcers, tumors, etc. Dose of powdered bethroot one drachm, to be given in hot water; of the strong infusion, which is the most common form of administration, from two to four fluidounces. These plants undoubtedly possess active properties, and deserve further investigation. TRIOSTEUM PERFOLIATUM. Fever-root. Nat. Ord.—Caprifoliaceaa. Sex. Syst.—Pentandria Monogynia. BARK OF THE ROOT. Description.—This plant is known also by the names of Wild Ipecac, Horse- Gentian, Wild Coffee, and Dr. Tinker's Weed. It is indigenous, with a perennial, thick and fleshy root, subdivided into numerous hori- zontal branches. The stems are several from the same root, simple, stout, erect, round, hollow, soft, pubescent, and from two to four feet high. The leaves are opposite, oval-acuminate, mostly connate, entire, abruptly contracted at base, nearly smooth above, pubescent beneath, prominently veined, and six inches long by three broad ; in some plants the upper leaves are almost amplexicaul. The flowers are of a dull purple color, axillary, sessile, mostly in clusters of three or five in the form of whorls, rarely solitary. The calyx is composed of five linear segments of a purplish color, with a single bract ; the corolla is rather longer than the calyx, tubular, five-lobed, viscid-pubescent, the lobes rounded, and the lower part of the tube gibbous. The stamens are five, included, with hairy filaments. The ovary is inferior, roundish, and supports a long, slender style, with an oblong stigma. The fruit is an oval berry, about nine lines long and six thick, of an orange-red or purple color when ripe, hairy, somewhat three-sided, crowned with the persistent calyx, three-celled, each cell containing a hard, bony, furrowed seed. History.—Fever-root is found in many parts of the United States, in shady and'rocky situations, and in rich soil, flowering in June and July. The bark of the root is the officinal part; it is horizontal, long, from 934 Materia Medica. half an inch to three-quarters of an inch in diameter, of a brownish or yellowish color externally, whitish within, and furnished with fibers. It has a nauseous odor, and an unpleasant, bitter taste, and when dried is brittle, and easily pulverized. Water or alcohol takes up its virtues. It has not been analyzed. The Triosteum Angustifolium, smaller than the above, with a bristly, hairy stem, lanceolate, and sub-connate leaves, tapering to the base, peduncles opposite, one-flowered, and flowers of a greenish-cream color, possesses analogous properties, and may be substi- tuted as an equivalent for the above. Properties and Uses.—The bark of the root is emetic when recent, or when taken in large doses of the powder. In doses of from a scruple to a drachm, the powder is a mild, but slow cathartic, with a tonic influ- ence. In the early stages of fever, it may be given in all cases where a gentle action on the bowels is desired. It has been recommended as a laxative-tonic in dyspepsia, and autumnal fevers, also in hysteria, hypo- chondria, and convalescence after febrile diseases. Some have stated it to possess diuretic properties, and have employed it in chronic rheuma- tism with success. Rafinesque considers the leaves to be diaphoretic. The hard seeds are said to be a very excellent substitute for coffee, when properly prepared. Dose of the tincture from one to four fluidrachms; of the extract, which is the best form of administration, from five to fifteen grains. TRITICUM HYBERNUM. Wheat. Nat. Ord.—Graminaceaa. Sex. Syst.—Triandria Digynia. FLOUR OF THE SEEDS. Description.—This plant, the common Winter Wheat, described as T. Sativum, and T. Vulgare, has a fibrous root, and one or more erect, round, smooth, jointed stems, from three to five feet in hight, with the internodes somewhat inflated. The leaves are linear, pointed, entire, flat, many-ribbed, rough, somewhat glaucous, with truncate, jagged-bearded stipules. The flowers are in a solitary, terminal, dense, smooth, imbri- cated, somewhat four-sided spike, two or three inches long, with a tough rachis. Spikelets crowded, broad-ovate, about four-flowered ; glumes ventricose, ovate, truncate, mucronate, compressed below the apex, round and convex at the back, with a prominent nervure. Paleas of the upper florets somewhat bearded. Grains loose. History.—Several species of Triticum are cultivated in different coun- tries, among which may be named the T. Vulgare, the species most generally raised in this country and Europe. It has two varieties, T. Vulgare JEstivum or Spring-Wheat, and T. Vulgare Hybernum, or Win- ter-Wheat. Linnaeus considered these as distinct species, but Botanists Triticum Hybernum. 935 of the present day generally refer them to one common stock. Wheat differs from barley and oats, in not having the perianth adherent to the grain. Its native country is unknown, but is commonly supposed to have been Central Asia. The officinal part of the plant is the flour of the seeds; these are first deprived of their husks, and are then reduced to flour by grinding and sifting; the interior farinaceous part forming the farina or flour, which varies in its degree of fineness, while the covering or external coat, which constitutes from 25 to 33 per cent, of the seeds, furnishes what is called bran. Wheat flour is very white, of a faint, peculiar odor, and nearly taste- less. It consists chiefly of starch, gluten, albumen, saccharine matter, gum, a little ligneous fiber, and some moisture, which vary considerably in their proportions, in different samples. The starch is the most abun- dant ingredient, and is of finer quality and of greater density than that obtained from most other sources. (See Amylum.) The gluten of wheat is generally assumed as the most perfect form of that principle, and is more abundant in wheat than any other grain; and it is to the greater proportion of this principle, that wheat flour owes its superiority over that from other grains for the preparation of bread. When wheat flour, inclosed in a linen bag, is exposed to the action of a stream of water, and at the same time pressed with the fingers till the liquor comes away colorless, the portion which is left in the bag consists of gluten and vegetable albumen, which may be separated by boiling in alcohol. The gluten being dissolved by the alcohol, and the vegetable albumen not being affected by it. Each of these substances contain nitrogen, and when left to themselves in a moist state, undergo putrefaction. By placing the alcoholic solution of gluten, previously filtered while hot, into water, and distilling off the alcohol, the gluten will float on the top of the water in large cohering flakes. It may be still further purified by treating it with ether, to remove fat oil. Pure gluten, at present called Vegetable Fibrin, is a pale-yellow, adhe- sive, elastic substance, becoming darker-colored and translucent when dried, somewhat like horn. It is insoluble in water, ether, and in the fixed and volatile oils. Boiling alcohol dissolves it more readily than cold. It forms soluble compounds with diluted acids or alkaline solu- tions ; and nearly insoluble compounds with the earths and metallic oxides, which are precipitated when the earths or oxides are added to the solution of gluten in liquid potassa. Its acid or alkaline solutions are precipitated by corrosive sublimate, which, on being added in solu- tion to moist gluten, forms a compound, which, when dry, is hard, opake and incorruptible. Infusion of galls also precipitates gluten. This principle exists in most of the farinaceous grains, and in the seeds of some leguminous plants. Vegetable Albumen possesses no adhesiveness, and, when dried, is opake, and of a white, gray, or brown color. It exists in a soluble 936 Materia Medica. form in vegetables, and especially in the oily seeds, along with caseine. Before coagulation it is soluble in water, but insoluble in alcohol. When heated to from 140° to 160°, it coagulates, and becomes insoluble in water. Its solutions are also coagulated by acids, infusion of galls, creosote, and corrosive sublimate. It is dissolved by solutions of the caustic alkalies. When a fresh vegetable juice is filtered and boiled, it yields a coagulum, which is nearly pure albumen. It is a constituent of all the seeds which form a milky emulsion with water, and in most of them is associated with gluten. It is to vegetable fibrin and albumen, aided by a moderate heat and the presence of water, that starch is converted partly into gum and partly into sugar, as in the germination of seeds ; the gluten becoming acid in the process, loses its power of reacting on the starch. As far as ascertained, vegetable albumen is identical with animal albu- men, and the gluten of vegetables with animal fibrin ; and these, Avith casein, a principle existing in both the animal and vegetable kingdoms, consist of protein in combination with a small proportion of mineral substances, as sulphur and phosphorus. Protein is compounded of nitrogen, carbon, hy- drogen and oxygen, its formula being Ne Ci8 H3J Ou. It may be obtained by dissolving any of the above-named substances in a strong solution of potassa, heating for some time to 120°, and precipitating with acetic acid. Bread is formed by making a thick paste with wheat flour and water, adding a little salt, and some yeast, setting it aside to ferment, and then baking it. The carbonic acid gas which is extricated during the fermentation, is retained by the tenacity of the gluten, forming numerous small cells through the mass, and thus renders the bread light. Properties and Uses.—Wheat flour in its unaltered state is seldom used in medicine. It is sometimes sprinkled on the skin in erysipelatous inflammation, and various itching or burning eruptions, particularly the nettle-rash ; though rye-flour is generally preferred for this purpose. In the state of bread it is much more employed. An infusion of toasted bread in water is a pleasant, somewhat nutritive drink, very well adapted to febrile complaints. Within our experience, no drink has been found more grateful in such cases than this infusion sweetened with a little molasses, and flavored by lemon-juice. Boiled Avith milk, bread consti- tutes the common suppurative poultice, which may be improved by the addition of a small proportion of perfectly fresh lard. Slices of it steeped in borax water, or the crumb mixed with the fluid and confined within a piece of gauze, afford a convenient mode of applying this preparation to local inflammations. The crumb—mica panis—is, moreover, frequently used to give bulk to minute doses of very active medicines administered in the form of pill. As bread contains salt, its incompatibilities, as for in- stance, nitrate of silver, should be remembered, when forming pills with it. Bran is sometimes used in decoction, as a demulcent in catarrhal affections and complaints of the bowels. It has, when taken in substance, Triticum Hybernum. 937 laxative properties, and is used by some persons habitually and with great advantage to prevent costiveness. Bran bread, made from the unsifted flour, forms an excellent laxative article of diet in some dys- peptic cases. The action of the bran is probably altogether mechanical, consisting in the irritation produced upon the mucous membrane of the stomach and bowels by its coarse particles. We are indebted to Dr. T. J. Wright, of Cincinnati, for the following remarks on wheat, the correctness of which has been corroborated by other physicians who have made use of it according to his method. His mode of preparing and using it is as follows: " The seeds of wheat should be well cleaned before cooking them, in the following manner : Take of the seeds of wheat a sufficient quantity, and place them in clear, cold water, stir it, and skim off the light grains which rise to the surface in connection with foreign substances ; then change the water, stir the grain, and skim as before, and thus continue till the wheat is perfectly clean, and all the light grains and extraneous substances are removed. To the wheat, thus cleansed, add a sufficient quantity of water to cover it, and allow it to stand for twelve hours, or until the next morning, if this is done at night; then pour off the liquid, and add of some clean water a sufficient quantity, and boil for from two to four hours, or until the spermoderm is cracked, when remove the wheat from the water, let it cool, and it is ready for use. Of this pre- pared wheat, small quantities ought to be made at a time, especially in warm weather, as it is apt to become sour; enough for one or two days at the most, is sufficient, and it should always be kept in a cool place. " There are several ways in which this preparation can be used, viz: It may be eaten with molasses or sugar, as boiled rice is sometimes eaten ; or it may be made into a frumenty, by boiling a sufficient quan- tity of milk, and thickening it with flour to the consistence of gruel; remove from the fire, add as much prepared wheat as desired, and sweeten. But the preparation which I prefer, is to use water instead of milk, and thicken with Indian meal to the consistence of gruel, then remove from the fire, add prepared Avheat in quantity to suit the patient and sweeten. Wheat thus prepared, undoubtedly acts mechanically, owing to the action of the coarse particles upon the intestinal mucous lining membrane, which maintain the peristaltic motion and keep the boAvels in a soluble condition ; and in addition to its nutritive qualities, prepared wheat is one of the most valuable articles of diet for patients, and may be used either in a loose or torpid state of the bowels. In dyspepsia, fistula in ano, hemorrhoids, constipation, as well as the opposite condition, the employment of it is not only beneficial, but mate- rially assists in their cure. I have extensively used the above in obsti- nate constipation, chronic diarrhea, and other diseases, with decided advantage in every case, and can, therefore, confidently recommend i< to my medical brethren." 938 Materia Medica. TUSSILAGO FARFARA. Coltsfoot. Nat. Ord.—Asteraceae. Sex. Syst.—Syngenesia Superflua. THE LEAVES. Description. — Coltsfoot has a long, perennial root, with the leaves radical, cordate, on downy, furrowed petioles somewhat lobed and toothed, smooth and dark-green above, Avhite, veined, and tomentose beneath, and from five to eight inches long, by three to six wide; when young, the leaves are revolute, and covered with a cottony down; they arise after the flowers have withered. The scapes are several, and appear before the leaves; they are erect, slender, round, varying in color from pale-green to reddish-brown, one-flowered, and beset with numerous lanceolate scales ; their hight is from five to six inches. The fiowers are large, yellow, compound; the florets of the ray being ligulate, numerous, and fertile, while those of the disk are few, tubular, and barren. The scales of the involucre are linear-lanceolate, equal to the disk, at first erect, but finally reflexed. The achenia are smooth, oblong, and compressed; the pappus is pilose, sessile, silvery, and permanent. History. — This plant is very common in Europe, and has become naturalized in this country, especially in the Northern States; it flowers in April. The root is mucilaginous, bitterish, creeping horizontally, with many fibers. It grows in wet places and low meadows. The flowers have an agreeable odor, which they retain when dried. The whole plant is medicinal, but the leaves are principally employed. They should be gathered after their full expansion, but before they have attained their greatest magnitude. The dried leaves and root are inodo- rous, and have a rough, bitter, mucilaginous taste, and impart their properties to boiling water. No analysis has been made of them. Properties and Uses.—Coltsfoot is emollient, demulcent, and slightly tonic. Useful in coughs, asthma, hooping-cough, and other pulmonary affections ; and is said to have been useful in scrofula. The powdered leaves form a good errhine, for giddiness, headache, nasal obstructions, etc. Used externally in form of poultice to scrofulous tumors. TYPHA LATIFOLIA. Cat-tail Flag. Nat. Ord.—Typhaceaa. Sex. Syst.—Moncecia Triandria. THE ROOT. Description.—Cat-tail Flag, or Reed Mace, as it is sometimes called, is a perennial plant, with a smooth, round stem, from three to five feet high, leafy below, and terminated by large cylindric spikes. The leaves are flat, erect, ensiform, slightly concave within near the base, from two Ulmus Fulva. 939 to four feet long, and nearly one inch wide. The flowers are very nu- merous. The spikes are of a brownish color, from six to ten inches in leno-th, and about one inch in diameter, and are composed of slender, downy flowers, so compact, particularly the fertile ones, as to be of con- siderable hardness. The upper portion is smaller, and composed of the sterile flowers, so that the staminate and pistillate parts of the spike approximate, or are almost continuous. History.—This plant is common to all parts of the United States, and is found growing in ditches, muddy pools, borders of ponds, and other wet places, flowering in July. The leaves are called Flags, and are used for weaving the seats of chairs; the flowers have been used for making beds. The root is the part used; it yields its properties to water. Properties and Uses.—Astringent and emollient. Boiled with milk, it has been found useful in dysentery, diarrhea, and infantile summer com- plaint, and a decoction of it has been beneficial in gonorrhea. Exter- nally, the root, in combination with elm and aromatics, forms an excellent poultice for white swellings, tumors, and ulcers. The root, bruised until it becomes like a jelly, forms an excellent application for burns and scalds, erysipelas, ophthalmia, and all local inflammations. ULMUS FULVA. Slippery Elm. Nat. Ord.—Ulmaceaa. Sex. Syst.—Pentandria Digynia. THE INNER BARK. Description.—Slippery Elm, also called Red Elm, is a tree from twenty to sixty feet in hight, and one or two feet in diameter. The bark of the trunk is brown, that of the branches rough and whitish. The leaves are oblong-ovate, acuminate, nearly equal at the base, unequally serrate, pubescent and very rough on both sides, four or five inches long by two or three in breadth, and supported on short footstalks. The buds are covered with fulvous down. The flowers appear before the leaves, are reddish, sessile, and in clusters at the ends of the young shoots ; the bunches of flowers are surrounded by scales, which are downy like the buds. The calyx is downy and sessile; corolla none ; stamens five or seven, according to the number of calyx lobes, short, and of a pale rose color. The fruit is a membranaceous capsule or samara, nearly orbic- ular, containing in the center one round seed, without any fringe. History.—The Slippery Elm is a lofty tree indigenous to all parts of the United States, but found in the greatest abundance west of the Alle- ghany mountains, in open and elevated situations, in rich, firm soil, and flowering in April. The inner bark is the part used in medicine ; it is in long, flat pieces, from one to two lines in thickness, of a fibrous tex- ture, a tawny color, which is reddish on the inner surface, a peculiar 940 Materia Medica. sweetish, not unpleasant odor, and a highly mucilaginous taste when chewed. By grinding, it is reduced to a light, grayish-fawn-colored powder. Water takes up its mucilage, which is precipitated by solutions of acetate and subacetate of lead, but not by alcohol. Properties and Uses.—Elm bark is nutritive, expectorant, diuretic, demulcent, and emollient, and is a very valuable remedial agent. In mucous inflammations of the lungs, boAvels, stomach, bladder or kidneys, used freely in the form of a mucilaginous drink, it is highly beneficial, as well as in diarrhea, dysentery, coughs, pleurisy, strangury, and sore throat, in all of which it tends powerfully to allay the inflammation. A tablespoonful of the powder boiled in a pint of new milk affords a nour- ishing diet for infants weaned from the breast, preventing the bowel complaints to which they are subject, and rendering them fat and healthy. Some physicians consider the constant use of it, during and after the seventh month of gestation, as advantageous in facilitating and causing an easy delivery; a half pint of the infusion to be drank daily. Elm bark has likewise been successfully employed externally in cuta- neous diseases, especially in obstinate cases of herpetic and syphilitic eruptions, and certainly possesses higher curative powers than are gene- rally admitted. As an emollient poultice, the bark has been found very serviceable as an application to inflamed parts, suppurating tumors, fresh wounds, burns, scalds, bruises, and ulcers ; and in the excruciating pains of the testes Avhich accompany the metastatis of cynanche paroti- daea, Avhether of recent or long standing, the constant use of an elm poultice regularly changed every four hours will be found a superior remedy. As an injection, the infusion will prove useful in diarrhea, dysentery, tenesmus, and hemorrhoids, also in gonorrhea and gleet. The powder, sprinkled on the surface of the body, will prevent and heal excoriations and chafings, and allay the itching and heat of erysipelas. As the bark increases in bulk by imbibing moisture, it has been recom- mended to form bougies and tents of it for the dilatation of strictures, fistulas, etc., but in urethral strictures it has proved troublesome, from liability of the part behind the stricture, breaking off in the attempt to withdraw it, and passing into the bladder. The infusion of the bark is the common form of administration, and may be drank ad libitum. Off. Prep.—Cataplasma Ulmi; Infusum Ulmi. URTICA DIOICA. Common Nettle. Nat. Ord.—Urticaceaa. Sex. Syst—Moncecia Tetrandria. THE ROOT AND LEAVES. Description.—This plant, also called great Stinging Nettle, is a peren- nial, herbaceous, dull-green plant, armed Avith minute rigid hairs or Urtica Dioica. 941 prickles, which transmit a venomous fluid when pressed. The stem is obtusely four-angled, branching, and from two to four feet high, and arises from a creeping and branching root, with fleshy shoots and many fibers. The leaves are opposite, petiolate, cordate, lance-ovate, spread- ing, conspicuously acuminate, coarsely and acutely serrate, the point entire, armed with stings, three or four inches long, and about half as wide. The flowers are small, green, monoecious or dicecious, in branch- ing, clustered, axillary, interrupted spikes, longer than the petioles. History.—This is a well known plant, common to Europe and the United States, growing in waste places, by wood-sides, in hedges, and in gardens, flowering from June to September. A decoction of the plant strongly salted, will coagulate milk as readily as rennet, without impart- ing to it any unpleasant flavor. The leaA'es and root are generally used, and yield their virtues to Avater. No analysis has been made of the plant. The young shoots have been boiled and eaten as a remedy for scurvy. The irritation caused by applying the sharp hairs of the nettle to the skin, is said to be owing to the presence of free formic acid in them. Properties and Uses.—Common Nettle is astringent, tonic, and diure- tic. A decoction is valuable in diarrhea, dysentery, hemorrhoids, vari- ous hemorrhages, and scorbutic affections, and has been recommended in febrile affections, gravel, and other nephritic complaints. A strong syrup made of the root, combined with suitable quantities of wild cherry bark and blackberry root, forms an excellent remedy for all summer complaints of children, and bowel affections of adults. The leaves of the fresh plant, stimulate, inflame, and even raise blisters on those por- tions of the skin Avith which they come in contact, and have, in conse- quence, been used as a powerful rubefacient. Paralysis is said to have been cured by whipping the affected limbs Avith them. Applied to bleed- ing surfaces they are an excellent styptic. The seeds and flowers, given in wine, in doses not to exceed one drachm, have been reputed equal to cinchona in tertian and quartan agues — larger doses will, it is said, induce a lethargic sleep. The seeds, in doses of fourteen or sixteen seeds, and repeated three times daily, are highly recommended as a remedy for goitre, and to reduce excessive corpulence; they are also considered anthelmintic. Dose of the poAvdered root or leaves from twenty to forty grains ; of the decoction from two to four fluidounces. Urtica, Urens, or Dwarf Nettle, possesses similar properties, and has been found very efficacious in uterine hemorrhage. It has a branching, hispid, stinging stem, one or tAvo feet high, with broadly elliptic, acutely serrate leaves, about five-veined, on short petioles, one or two inches long, and about two-thirds as broad. The flowers are in drooping, pedunculate, nearly simple clusters, two in each axil, and shorter than the petioles. This is an annual, introduced from Europe. 942 Materia Medica. Urtica Pumila, Cool-weed, Rich-weed, or Stingless Nettle, has a pecu- liar, grateful, strong smell, indicating active properties ; it is stated that the leaves bruised give immediate relief in inflammations, painful swell- ings, ecchymosis, erysipelas, and the topical poison of rhus; and that an ointment made from it is beneficial in inflammatory rheumatism. It is the Pilea Pumila of Lindley, and has a smooth, shining, ascending, weak and succulent, often branched, and translucent stem, from four to eighteen inches high, and, together with the whole plant, destitute of stings. The leaves are on long petioles, opposite, rhombic-ovate, cre- nate-serrate, membranaceous, glabrous, pointed, three-nerved, about two inches long, and two-thirds as broad. The flowers are monoecious, triandrous, in axillary, corymbed heads shorter than the petioles. Sepals of the fertile flowers lanceolate, and a little unequal. This plant is worthy of further investigation. UVARIA TRILOBA. Papaw. Nat. Ord.—Anonaceaa. Sex. Syst.—Polyandria Polygynia. THE SEEDS. Description.—This is the Porcelia Triloba of Michaux, and the Asi- mina Triloba of Adamson, it is a small and beautiful indigenous tree, growing from ten to twenty feet high. The young shoots and expanding leaves clothed with a rusty down, soon glabrous. The leaves are thin, smooth, entire, ovate-oblong, acuminate, from eight to twelve inches long, by three or four broad, and tapering to very short petioles. The flowers are dull purple, axillary and solitary; the petals veiny, round- ovate, the outer ones orbicular and three or four times as large as the calyx. The flowers appear with the leaves, and are about an inch and a half wide. The fruit is a yellowish, ovoid-oblong, pulpy pod, two or three inches long by about an inch in diameter, fragrant, sweet and edible in autumn, and containing about eight seeds. History.—The Papaw or Custard Apple-tree is an inhabitant of the Middle, Southern, and Western States, growing in rich soil, and on the banks of streams, and floAvering from March to June. The fruit is large and fleshy, and has an unpleasant smell, but when ripe and after frost, the pulp is sweet, luscious, and yelloAv, similar to custard; it is consid- ered a healthy fruit, and is sedative and laxative. The seeds, which are the parts used, have a fetid smell, similar to stramonium; they are covered with a tough, hard, exterior coat, of a light-brownish color and smooth externally, lighter and wrinkled internally, inclosing a kernel of a whitish-yellow color, compressed, deeply fissured on both sides, nearly inodorous, very faintly bitter and sweetish, and dry and branny when chewed, leaving a very persistent, faint, but rather unpleasant sensation UVULARIA PERFOLIATA. 943 of nausea. They are of various shapes, being flat, ovoid, nearly circu- lar, or somewhat reniform, with a longitudinal furrow or depression along the center of each of the flat surfaces, and frequently a ridge or eleva- tion instead of the furrow. They yield their properties to alcohol. Properties and Uses.—Emetic ; for which purpose a saturated tincture of the bruised seeds is employed, in doses of from ten to sixty drops. The bark is said to be a bitter tonic, and has been used as such in domestic practice. The medical properties of this agent have not been fully investigated. UVULARIA PERFOLIATA. Bellwort. Nat. Ord.—Liliaceas. Sex. Syst.—Hexandria Monogynia. THE ROOT. Description.—Bellwort has a perennial, creeping rootstock, and a stem from eight to fourteen inches high, dividing at top into two branches. The leaves are clasping-perfoliate, elliptical, rounded at base, acute at apex, tAvo or three inches long by one-third as broad, smooth, glaucous underneath. The flowers are solitary, pale-yellow, about an inch long, and pendulous from the end of one of the branches; perianth subcam- panulate, tuberculate-scabrous within ; segments linear-lanceolate, about an inch long, twisted; anthers cuspidate, three-fourths of an inch long. Capsule or pod obovate-truncate, divergently three-lobed at top ; lobes with convex sides. History.—Bellwort is a smooth, handsome plant common to the United States, growing in moist copses, woods, etc., and flowering in May. The root is the part employed, which, when recent, is acrid and mucilagi- nous. It imparts its properties to water. Properties and Uses.—Bellwort is tonic, demulcent, and nervine, and may be used in decoction or powder, as a substitute for cypripedium. The decoction has proved beneficial in sore mouth and affections of the throat, also inflammation of the gums. A poultice of it is useful in wounds and ulcers. Boiled in milk, and the decoction drank freely, with a poultice of the root applied to the wound, it has considerable reputation as an alexipharmic in the bites of venomous snakes. A poul- tice of the green or dried root, in powder, and mixed with hot new milk, is very highly recommended in all stages of erysipelatous inflammation, to be renewed when dry; the same application has been used benefi- cially in acute ophthalmia. An ointment made by simmering the pow- dered roots and green tops in lard, for an hour, over a slow fire, and straining by pressure, is useful in herpetic affections, sore ears, mouths, etc., of children, and also in mild cases of erysipelas. 944 Materia Medica. VACCINIUM FRONDOSUM. Blue Whortleberry. Nat. Ord. — Ericaceaa. Sex. Syst. — Decandria Monogynia. THE fruit. Description.—This is a shrub from three to six feet high, with a gray- ish bark, and round, smooth, slender and divergent branches. The leaves are deciduous, obovate-oblong, obtuse, entire, pale, glaucous beneath, and covered with minute resinous dots, the margin being slightly revo- lute. The flowers are small, nearly globose, reddish-white, and arranged in loose, slender, lateral, bracteate racemes; bracts oblong or linear, rather deciduous, shorter than the pedicels ; pedicels from five to ten lines long, slender, drooping, bracteate near the middle. Corolla ovoid-cam- panulate, with acute divisions, and inclosing the stamens. Fruit large, globose, dark-blue, covered with a glaucous bloom, sweet and edible. Vaccinium Resinosum, Black Whortleberry or Huckleberry, is a bushy shrub from one to three feet in hight. The branches are cinerous-brown, and villose when young. The leaves are deciduous, oblong-ovate, or oblong-lanceolate, rather obtuse, entire, petiolate, one or two inches long, and about one-third as Avide, thickly covered with shining resinous dots beneath. The flowers are reddish, tinged with green, or yellowish- purple, and disposed in lateral, secund, dense, corymbose racemes, small and drooping; pedicels about the length of the flowers, sub-bracteolate ; brads and bractlets reddish, small, and deciduous. The corolla is ovoid- conic, at length subcampanulate, five-angled, contracted at the mouth, and longer than the stamens, but shorter than the style. Fruit globose, black, Avithout bloom, sweet and edible. History.—These plants are common to the Northern States, growing in woods and pastures, floAvering in May and June, and ripening their fruit in August. The fruit, or berries, together Avith the bark of the root are the parts used. They yield their virtues to Avater. The different varieties of Whortleberry possess similar properties, as the V. Dumosum, or Bush-Whortleberry, V. Corymbosum, or Giant- Whortleberry, V. Pennsylvanicum, or Black-blue-Whortleberry, V. Vitis Idcea, or Bilberry, and several others. Several species are found grow- ing in the mountainous regions of some of the Southern States. Torry and Gray have removed the V. Frondosum, V. Resinosum, and V. Du- mosum, from the genus Vaccinium, and placed them in a new one called Gaylussacia, in honor of the distinguished chemist, Gay-Lussac. Properties and Uses. — Diuretic and astringent. The fruit is very useful, eaten alone, with milk or sugar, in scurvy, dysentery, and derangements of the urinary organs. The berries and root, bruised and steeped in gin, form an excellent diuretic, which has proved of much Valeriana Officinalis. 945 benefit in dropsy and gravel. A decoction of the leaves or bark of the root is astringent, and may be used in diarrhea, or as a local application to ulcers, leucorrhea, and ulcerations of the mouth and throat. Both the berries and root-bark of V. Arboreum, or farkleberry, are very astrin- gent, more so than the other varieties above-named, and may be used in all cases where this class of agents is indicated. VALERIANA OFFICINALIS. Valerian. Nat. Ord.—Valerianaceaa. Sex. Syst.—Triandria Monogynia. THE ROOT. Description.—The officinal Valerian, sometimes known as Great Wild Valerian, is a large, handsome, herbaceous plant, with a perennial, short, tuberculated rhizome, from which issue many long, slender fibers of a dusky-brown color, and having a fetid smell. The stem is erect, hollow, smooth, furrowed, and about three or four feet high. The leaves are of a deep glossy-green, serrated, somewhat hairy beneath, opposite, pinnate, but differing in the number of leaflets. The loAver leaves are generally furnished Avith ten pairs, those of the stem with nine, and the upper ones with from five to seven; the leaves of the stem are attached by short broad sheaths, the radical ones are larger, and have long petioles. The leaflets of the stem are lanceolate and partially dentate, those of the radical leaves are elliptical and deeply serrate. The flowers are small, of a reddish-white color, fragrant, and disposed in dense corymb-like panicles, terminal and perfect. Bracts ovate-lanceolate, acuminate, herbaceous, membranous at the edge, appressed, rather longer than the ovary. The calyx is superior, rolled inward in the form of a rounded thickened rim, finally expanding into a kind of pappus to the seed. The corolla is funnel-shaped and smooth; the tube gibbous at the base on that side of the flower turned away from the axis, hairy internally; limb spreading, divided into five nearly equal, concave, linear, rounded segments. The stamens are three, exserted, subulate, white, from the middle of the corolla-tube, with oblong yellow anthers. The ovary is inferior, narrow-oblong, compressed, one-celled, with a single pendulous ovule; style filiform; stigma divided into three filiform lobes. Fruit light-brown, linear-ovate, compressed, with a slightly ele- vated ridge on one side, terminated by the twelve filiform, plumose, recurved segments of the calyx-limb. History.—Valerian is a European plant growing in damp woods and meadows, and sometimes in dry banks; those found in dry elevated situations, present botanical differences of a marked character, and are considered superior to the others in medicinal virtue. The plant flowers in June and July. There are several varieties growing in this country. 60 946 Materia Medica. The root isj&the officinal portion, and consists of long, slender, cylindri- cal fibers, about four inches in length, and half a line in thickness, issuing from a tuberculated head or rhizoma. It should be collected in spring before the stem begins to shoot, or in the autumn when the leaves decay, and should be dried quickly and kept in a dry place. Exter- nally, its color is yellowish or brown, and internally white, and when dried it possesses a strong, peculiar odor, very disagreeable to many per- sons, and a taste at first sweetish, afterward bitter and aromatic; its powder is yellowish-gray. It imparts its properties readily to water, rec- tified spirit, or ammoniated spirit. The best valerian is obtained from England. Valerian contains volatile oil, a peculiar extractive matter, soluble in water, insoluble in ether or alcohol, and precipitated by me- tallic solutions, gum, soft odorous resin, and lignin. Among these the most important is the essential oil, in which the virtues of the root chiefly reside; it is of a pale-greenish color, becoming yellow and viscid by exposure, of specific gravity 0.934, with a powerful, penetrating valerian odor, and a warm aromatic taste. It may be obtained by dis- tillation of the root with Avater. An acid, termed Valerianic acid, is obtained by oxidation of the volatile oil; it is a colorless liquid, oleagi- nous in consistence, having a valerian odor, a very strong, sour, disa- greeable taste, and forming salts with salifiable bases. This acid' can likewise be obtained by the action of caustic potassa on the oil of potato spirit. Valerianic acid may also be prepared by distilling 100 parts of valerian root with 500 of water, 10 of sulphuric acid, and 6 of bichro- mate of potassa; or, boil valerian root for three hours in rather more than its bulk of water, in Avhich an ounce of carbonate of soda is dis- solved for every pound of the root, replacing the Avater as it evaporates. Express strongly, and boil the residuum twice Avith the same quantity of Avater, expressing each time as before. Mix the liquids, add two fluidrachms of strong sulphuric acid for every pound of the root, and distil till three-fourths of the liquid have passed over. Neutralize this with carbonate of soda, concentrate the liquid, decompose the valerian- ate of soda contained in it by sulphuric acid, and separate the valerianic acid now set free, either by a separatory or by distillation. Gruneberg recommends the following: Take 2| lbs of bichromate of potassa, intro- duce it into a retort, and pour 41 lbs of hot water upon it. A cooled mixture of 1 lb of fusel oil and 4 lbs of sulphuric acid diluted with 2 lbs of Avater is to be alloAAred to flow very slowly and in a thin stream into the liquid in the retort, and the whole is then to be distilled. The distillation goes on quietly, and 9 ounces of oily valerianic acid are obtained. Properties and Uses.—Valerian is tonic, antispasmodic, and calmative. In large doses it produces a sense of heaviness and dull pain in the head, with other effects indicating nervous disturbance. It is useful in cases of irregular nervous action, as in the restlessness and irritability occur- Vanilla Aromatica. 947 ring in hysterical constitutions, in the morbid vigilance of fevers, in hypochondriasis, epilepsy, hemicrania, and occasionally in intermittent and remittent fevers. It may be used in powder or infusion, the latter being less liable to irritate the alimentary canal; the tincture is also officinal. The extract or decoction should not be employed, as the virtue of the root resides in a volatile oil. Dose of the powder from thirty to ninety grains, three or four times a day; of the infusion from one to two fluidounces; of the tincture from half a fluidrachm to two fluid- drachms; of the oil from four to six drops.

VANILLA AROMATICA. Vanilla. Nat. Ord.—Vanillaceaa. Sex. Syst.—Gynandria Monandria. THE FRUIT OR PODS. Description.—Vanilla Aromatica is a shrubby, climbing, aerial parasite, it commences its growth in the crevices of rocks, or on the trunks of trees, suspending itself to contiguous objects, and finally becomes de- tached from its original support, being truly an aerial plant. Planted in the woods or in warm ravines, it grows rapidly, fastening upon the trees in its neighborhood, especially those whose barks are soft and spongy. The stem is round, about as thick as the finger, from twenty to thirty feet in length, and often smaller at the base than at the sum- mit. The leaves are alternate, oblong, entire, on short petioles, glaucous, green, fleshy, and pointed by a species of abortive tendril, which is a continuation of the midrib; opposed to each leaf are one or two aerial roots, which attach themselves to surrounding objects. The flowers are axillary, paniculate, yelloAvish-white at base, and attended with one green bract; they expand one after another and endure only for a day. The ovaries appear at first view to be peduncles, they are erect after fecundation, and then become pendulous as they enlarge. The fruit is a silique or species of bean, yellow or buff color, of an agreeable aro- matic odor, and filled with a pulpy matter containing acicular crystals of an impure benzoic acid. They must be dried with care or they lose their properties. History.—Vanilla grows in the West Indies, Mexico, and South Ame- rica. The pods are collected before they are quite ripe, dried in the shade, covered over with a coat of fixed oil, and then tied in bundles, which are surrounded with sheet-lead, or inclosed in small metallic boxes, and sent into the market. There are several varieties of vanilla in commerce, the most valuable consisting of cylindrical, somewhat 948 Materia Medica. flattened pods, six or eight inches long, three or four lines thick, nearly straight, narrowing toward the extremities, bent at the base, shining, and dark-brown externally, wrinkled longitudinally, soft and flexible, and containing within their tough shell a soft black pulp, in which numerous minute, black glossy seeds are imbedded. It possesses a warm, aromatic, sweetish taste, and a strong, peculiar, but agreeable odor. It yields its virtues to water or alcohol. Properties and Uses.—Aromatic stimulant. Useful in infusion in hys- teria, rheumatism, and low forms of fever. It is also considered an aphrodisiac, powerfully exciting the generative system. Much used in perfumery, and to flavor tinctures, syrups, ointments, chocolate, ice- cream, etc. Dose of the powder, from eight to ten grains; of the infu- sion, made in the proportion of half an ounce to a pint of boiling water, half a fluidounce, three or four times a day. VERATRUM ALBUM. White Hellebore. Nat. Ord.—Melanthaceaa. Sex. Syst.—Polygamia Moncecia. THE RHIZOMA. Description.—By some Botanists this plant is placed in the class and order of the Sexual System, Hexandria Trigynia. Veratrum Album is a herbaceous plant, with a perennial, fleshy, oblong, somewhat horizon- tal, premorse rhizoma, about the thickness of a finger, blackish, or yel- lowish-white externally, whitish, or pale yellowish-gray internally, and beset with long cylindrical fibers of a grayish color, which constitute the true root. The stem is erect, thick, round, striated, and from one to four feet in hight. The leaves are alternate, broad-ovate, acute, entire, plaited longitudinally, and about ten inches long by five broad; they are of a yellowish-green color, and embrace the stem at their base. The flowers are yellowish-white, green at the back, eight lines in diameter, and disposed in a terminal panicle; the segments spreading, serrulate, and somewhat wavy. In other respects it resembles the Veratrum Viride. History. —White Hellebore is a native of Europe, growing in the mountainous regions of that country, especially on the Alps and Pyr- enees. The Avhole plant is active and poisonous, but the rhizoma only is officinal. When dried it is usually found in pieces, from one to three inches long, and nearly an inch in diameter, cylindrical, or in the shape of a truncated cone, whitish or grayish-brown internally, blackish exter- nally, wrinkled, and rough with the remains of the fibers which have been cut off near their origin. It deteriorates by keeping. Its odor is disagreeable when recent, but which is lost by drying, and its taste at first SAveetish, becomes intensely and permanently bitter, acrid, and burning. Diluted alcohol is its best solvent. The pulverized root is of Veratrum Sabadilla. 949 a grayish color. It contains supergallate of veratria, an oily substance consisting of olein, stearin, and a volatile acid, yellow coloring matter, starch, gum, lignin, silica, and various salts of lime and potassa. Tavo other principles have likewise been detected by Simon, named barytina and jervina. Its properties are owing to the veratria it contains. (See Veratria.) Properties and Uses.—White Hellebore is a violent emetic and purga- tive, and has been used in mental diseases, as a diaphoretic in chronic cutaneous diseases, and as a sternutatory in headache, amaurosis, and ophthalmia. Seldom used, however, except externally in the form of decoction or ointment for the cure of itch and other cutaneous eruptions, and as an errhine, diluted with six or seven parts of some mild powder, in gutta serena and lethargic affections. A mixture of three parts of the wine of White Hellebore, and one of the wine of opium has been considerably employed in gouty and rheumatic affections. White Helle- bore is a violent, irritant poison, producing, when snuffed up into the nostrils, severe coryza, and when swallowed, urgent vomiting, and pro- fuse diarrhea. When it proves fatal, narcotic symptoms, as stupor and convulsions, are superadded. Dose of the powder, from one to eight grains gradually and cautiously increased, commencing with one grain; of the vinous tincture, from twenty to sixty minims. Its use always requires great care.

Description. — The precise origin of this remedy is yet involved in uncertainty; by some, Cevadilla is referred entirely to the Veratrum Offici- nale, which has been variously denominated Helonias Officinalis, and Asagrcea Officinalis ; while others consider it the product of the V. Saba- dilla and A. Officinalis, Avith other plants of the same order. More exact information is required before its origin can be positively determined. The following is a description of two plants from which it is reputed to be obtained:— Veratrum Sabadilla of Retzius is a plant three or four feet high, with the leaves radical, numerous, spreading on the ground, ovate-oblong, obtuse, with from eight to fourteen ribs, and glaucous beneath. The scape or flower-stem is erect, simple, and round, and bears a spreading, simple, or but slightly branched panicle of somewhat nodding flowers, supported upon very short pedicels. The floAvers are blackish-purple, 950 Materia Medica. approximate in twos and threes; the fertile eventually becoming turned to one side, and the sterile falling off and leaving a scar. The segments of the perianth are ovate-lanceolate, and veinless. The ovaries are three, oblong, connate, obtuse ; styles acute, dilated downward; stigmas simple. Capsules three, in form resembling those of Larkspur, occupying only one side of the stem, and opening at the apex inside. Seeds three in each cell, imbricated, curved, blunt on one side, sooty, acrid. This plant grows in Mexico and the West Indies. Asagr^ea Officinalis, Lindley, Veratrum Officinale, Schlechtendahl, and Helonias Officinalis of Don, is a caespitose plant, bulbous, with the leaves linear, tapering to a point, even, smooth, entire, channeled above, carinate at the back, about four feet long, by three lines broad. The scape is naked, about six feet high, round, simple, terminating in a very dense, straight, spike-like raceme, eighteen inches long. The perianth is deeply six-parted, spreading, yellowish-white, permanent, with linear, thick, veinless, obtuse segments, three of which are rather broader than the others. Filaments six, somewhat clavate, those opposite the broad segments of the perianth longer than the others, and all longer than the perianth. Anthers large, yellow, cordate, obtuse. Ovary formed of three cells, united by their sutures, Avith an obscure stigma. Follicles three, acuminate, papery ; seeds scimitar shaped, corrugated, winged. This plant is a native of the eastern side of the Mexican Andes, near Barranca de Tioselo, by the Hacienda de la Laguna, in grassy places. History.—Cevadilla seeds are brought from Vera Cruz, and usually occur mixed with the fruit of the plant. This consists of tri-capsular follicles, which open aboAre, and present the appearance of single capsules with three cells ; they are about three or four lines long, a line and a half thick, obtuse at the base, light brown, or yellowish, smooth, and containing in each capsule, one or two seeds. The seeds are elongated, pointed at each end, flat on one side and convex on the other, somewhat curved, two or three lines long, wrinkled, slightly winged, black or dark brown on the outside, whitish within, hard, inodorous, and of an exceed- ingly acrid, burning, and persistent taste. They contain veratria com- bined with gallic acid, fatty matter, cevadic or sabadillic acid being a peculiar, volatile fatty acid, yellow coloring matter, wax, gum, lignin, and other unimportant constituents. They yield about 0.58 parts of Areratria to every one hundred. Merck has also discovered a peculiar acid, which he has named veratric acid; it occurs in colorless crystals, is fusible and volatilizable without decomposition, but slightly soluble in cold water, more soluble in hot water, insoluble in ether, soluble in alcohol, reddens litmus paper, and forms soluble salts with the alkalies. (See Veratria.) Properties and Uses. — Cevadilla seeds have been employed as an anthelmintic, but require much caution in their administration, as they Veratrum Viride. 951 are a dangerous, acrid, drastic emeto-cathartic. They have also been employed for the destruction of vermin in the hair, but should never be advised for this purpose, as dangerous consequences have resulted from this application of them. Externally applied they are very irritating. The dose is from fiAre to thirty grains, for the expulsion of taenia, and other worms. An extract has proved beneficial in painful rheumatic and neuralgic affections. At present, they are seldom used in practice, their chief employment being for the preparation of veratria. Off. Prep.—Veratria. VERATRUM VIRIDE. American Hellebore. Nat. Ord.—Melanthaceaa. Sex. Syst.—Polygamia Moncecia. THE RHIZOMA. Description.—This plant, known also by the names of Swamp Helle- bore, Indian Poke, and Itch-weed, has a perennial, thick and fleshy rhizoma, tunicated above, solid below, and sending forth numerous whitish radicles. The stem is annual, round, solid, striated, pubescent, and from three to six feet high, being, throughout the greater part of its length, closely invested with the sheathing bases of the leaves. The leaves are alternate, and gradually decrease in size as they ascend; the lower are from six to twelve inches long, oval, acuminate, pubescent, strongly ribbed and plaited, the lower part of their edges meeting round the stem; the upper leaves are gradually narrower; the uppermost or bracts linear-lanceolate. The flowers are numerous, yellowish-green, and arranged in compound racemes, axillary from the upper leaves, and terminal ; each flower is accompanied with a boat-shaped, acuminate, downy bract, much longer than its pedicel; peduncles roundish, downy. The perianth is divided into six oval, acute, nerved segments, of which the alternate ones are the longest, and all contracted at the base into a sort of claw with a thickened or cartilaginous edge. The stamens are six, with recurved filaments, and roundish, two-lobed anthers. Ovaries three, cohering, with acute recurved styles as long as the stamens. The fruit consists of three capsules, united together, separating at top, and dehiscing on their inner side. Seeds flat, winged, imbricated. A part of the flowers at the upper end of the branchlets are barren, and have only the rudiments of styles, those on the lower portion are fruitful. History. — American Hellebore is indigenous to many parts of the United States, usually growing in swamps, wet meadows, and on the banks of mountain streamlets, flowering from May to July. The rhizoma is the officinal part; it should be collected in autumn, and not kept longer than one year, as its virtues are rapidly impaired by age. It consists of a tunicated top, with a thick, fleshy base, having numerous radicals 952 Materia Medica. attached. When recent it has a disagreeable, fetid odor, which disap- pears on desiccation. The taste is at first sweetish, afterward bitter, followed by an acrid, pungent, and persistent sensation. In its appear- ance, as well as its sensible properties, it somewhat resembles white hellebore, and according to Mr. Worthington, of Philadelphia, it con- tains veratria, gallic acid, extractive, etc. Mr. W. precipitated a cold infusion of the root with subacetate of lead, separated the excess of lead with sulphureted hydrogen, evaporated to one-half, boiled with an excess of magnesia. The precipitate was collected on a filter, dried, treated with boiling alcohol and animal charcoal, and the filtered alcoholic solu- tion evaporated. The light-colored pulverulent residue was nearly inso- luble in water, more soluble in ether, and very soluble in alcohol. It melted when heated, and burned without residue ; had a burning acrid taste, acted powerfully as a sternutatory, and formed salts with the acids, of which the sulphate, tartrate, and oxalate only were crystallizable. From these properties, Mr. Worthington infers its identity Avith veratria; but it is probable that it is not veratria, but like colchicia, a distinct, though analogous principle. Properties and Uses.—Its effects upon the system are similar to those of the V. Album, although its cathartic action is denied by Dr. Osgood, who states that it reduces the frequency and force of the pulse, some- times as low as thirty-five strokes in the minute. It is also an emetic, and the action is often violent and long continued. In addition to which, it is said to increase most of the secretions, and when freely taken, to exercise a powerful influence over the nervous system, indicated by faint- ness, somnolency, vertigo, headache, dimness of ATision, and dilated pupils. Prof. Tully, of New Haven, regards it as an excellent substitute for colchicum, in gouty, neuralgic and rheumatic affections, to which diseases it seems best adapted. It is a remedy deserving the attention of the profession. The best forms of administration are the tincture or extract; and it should never be given in doses sufficient to produce vomiting. Dose of the powder, from four to six grains; of a saturated tincture, ten drops gradually increased until some effect is produced; of the extract, or inspissated juice, one-third of a grain, gradually increased. The V. Parviflorum and V. Angustifolium, of this country, are probably active, and should be examined. Dr. W. C. Norwood, of Cokesbury, S. C, in some recent communi- cations published in the Southern Medical and Surgical Journal, states that from actual experiments made by himself this plant has proved:— 1. Slightly acrid, and confining this action mostly to the mouth and fauces. 2. Expectorant, and unsurpassed by any other article for which this property is claimed. 3. Diaphoretic, being one of the most certain belonging to the Materia Medica; often exciting great coolness or coldness of the surface; some- Veratrum Viride. 953 times rendering the skin merely soft and moist, and at others producing free and abundant perspiration, without reducing or exhausting the system. 4. Adanagic, deobstruent, or alterative, far surpassing iodine, and from which much advantage may be expected in the treatment of cancer and consumption. 5. Nervine, and never narcotic. This property renders it of great value in the treatment of painful diseases, and such as are accompanied with spasmodic action, convulsions, morbid irritability, and irritative mo- bility, as in chorea especially, epilepsy, pneumonia, puerperal fever, neuralgia, etc. And it produces its effects in this respect, without stupe- fying and torpifying the system, as opium is known to do. 6. Emetic ; it is slow, but certain and efficient, rouses the liver to action during its operation, and vomits without occasioning the prostra- tion or exhaustion which follows the action of most other emetics. It is also superior to the majority of emetics, in not being cathartic. It is peculiarly adapted as an emetic in hooping-cough, croup, asthma, scarlet fever, and in all cases where there is much febrile or inflammatory action. 7. Arterial sedative. This he considers its most valuable and inter- esting property, and for which it stands unparalleled and unequaled as a therapeutic agent. 8. In small doses, it creates and promotes appetite, beyond any agent with which we are acquainted. Dr. Norwood recommends the following formula for the tincture: Take of the dried root of Veratrum Viride, eight ounces; alcohol .835 sixteen ounces. Macerate for two weeks, express, and filter. To an adult, eight drops are given, and which must be repeated every three hours, increasing the dose one or two drops every time, until nausea or vomiting, or a reduction of the pulse to 65 or 70 ensue; then reduce to one-half in all cases. Females and persons from fourteen to eighteen, should commence with six drops, and increase as above ; children from two to five years to begin with two drops, and increase one drop only; below two years of age, one drop. When nausea, vomiting, or other unpleasant effects ensue from its administration according to the above directions, they may be speedily relieved by one or two portions of syrup of morphia and tincture of ginger, or brandy and laudanum. He has reduced the pulse by its use, to 35 beats per minute, without exciting the least nausea or vomiting. In pneumonia, typhoid fever, and many other diseases, it must be continued for from three to five or seven days after the symptoms have subsided; and in typhoid fever, while using the veratrum, quinia is absolutely inadmissible. It is administered in a little sweetened water. Its employment may be continued indefinitely, in moderate doses, or short of nausea, without the least inconvenience. The correctness of Dr. Norwood's statements will be determined by future investigations. 954 Materia Medica. VERBASCUM THAPSUS. Mullein. Nat. Ord.—Scrophulariaceaa. Sex. Syst.—Pentandria Monogynia. THE LEAVES AND FLOWERS. Description.—Mullein is a biennial plant, with an erect, round, rigid, stout, hairy stem, from three to five feet in hight, and winged by the decurrent bases of the leaves. The leaves are alternate, oblong, acute, decurrent, indented at the margin, rough, and densely tomentose on both sides. The flowers are of a golden yellow color, rotate, nearly sessile, and are arranged in a dense, spiked, club-shaped raceme; calyx five- parted and downy; corolla five-lobed, rotate, lobes broad and rounded, somewhat unequal; stamens five, the two lower smooth, the rest downy. Capsule or pod, ovoid-globose, two-valved, many-seeded. History. — Mullein is common to the United States, growing in neglected fields, along roadsides, and in newly cleared places, floAvering from June to August. Some Botanists consider it to have been intro- duced from Europe. The leaves and flowers are the parts used. They have a slight, somewhat narcotic smell, rather agreeable, and a feebly mucilaginous, herbaceous, and bitter taste, and yield their virtues to boiling water. The flowers are said to contain volatile oil, yellow resin, saccharine matter, chlorophylle, malic and phosphoric acids. Properties and Uses. — Mullein is demulcent, diuretic, anodyne and antispasmodic. The infusion is useful in coughs, catarrh, hemoptysis, diarrhea, dysentery and piles. Its diuretic properties are rather weak, yet it is very useful in allaying the acridity of urine, which is present in many diseases. It may be boiled in milk, sweetened, and rendered more palatable by the addition of aromatics, for internal use, especially bowel complaints. A fomentation of the leaves also forms an excellent local application for inflamed piles, ulcers and tumors. The leaves and pith of the stalk form a valuable cataplasm in white swellings, and infused in hot vinegar or water, it makes an excellent poultice to be applied to the throat in cynanche tonsillaris, cynanche maligna, and mumps. The seeds, it is said, will rapidly pass through the intestines, and have been successfully used in intestinal obstructions. They are narcotic, and have been used in asthma, infantile convulsions, and to poison fish. The infusion may be drank freely. The flowers, placed into a well-corked bottle, and exposed to the action of the sun, are said to yield a fine relaxing oil. Off. Prep.—Cataplasma Verbasci. Verbena Hastata. 955 VERBENA HASTATA. Vervain. Nat. Ord.—Verbenaceaa. Sex. Syst.—Didynamia Gymnospermia. THE ROOT. Description.—Vervain, sometimes known by the names of Wild Hys- sop, or Simpler's Joy, is an erect, tall, elegant, and perennial plant, with an obtusely four-angled stem, three or four feet high, and having oppo- site, paniculate branches above. The leaves are opposite, petiolate, lanceolate, acuminate, rough, and incisely serrate ; the lower often lobed or somewhat hastate. The flowers are small, purplish-blue, sessile, tetrandrous, and arranged in long, erect, slender, imbricated, terminal and axillary, panicled spikes. Calyx five-toothed ; corolla funnel-form, limb five-cleft, nearly equal; seeds four. History.—Vervain is indigenous to the United States, growing along roadsides, and in dry, grassy fields, flowering from June to September. The root is the part used; it is woody and fibrous, faintly odorous and of a bitter, somewhat astringent, nauseous taste, and imparts its proper- ties to water. There are several varieties of this plant, as the V. Urti- cifolia, or nettle-leaAred vervain, with white flowers, the V. Spuria, with blue flowers, and others, the roots of which possess similar properties, but in a milder degree than the V. Hastata. Sometimes the leaves of V. Hastata are used instead of the root, but they are less active. Properties and Uses. — Vervain is tonic, emetic, expectorant, and sudorific. As an emetic and sudorific it has proved beneficial in inter- mittent fever, given in warm infusion or in powder. In all cases of colds and obstructed menstruation it may be used as a sudorific. Taken cold, the infusion forms a good tonic in some cases of debility, anorexia, and during convalescence from acute diseases. It has been reputed valuable in scrofula, visceral obstructions, gravel and worms. The fol- lowing application has been recommended as effectual in promoting the absorption of the blood effused in bruises, and in allaying the attendant pain : Take of vervain, senna and white pepper, of each equal parts. Make a cataplasm by mixing with the white of eggs. Dose of the pow- dered root, from one to two scruples ; of the infusion, from two to four fluidounces, three or four times a day, or oftener if it is desired to vomit. The root of V. Urticifolia boiled in milk and water, with the inner bark of Quercus Alba, and the decoction drank freely, is said to be an excel- lent antidote for poisoning from the Rhus Toxicodendron. The V. Officinalis is a European plant, possessing similar properties with the above, but less active. 956 Materia Medica. VERNONIA FASCICULATA. Ironweed. Nat. Ord.—Asteraceae. Sex.

The leaves are from four to eight inches long, by one or two broad, narrow-lanceolate, tapering to each end, serrulate, alternate, smooth above, the lower ones petiolate. The flower-heads are numerous, in a compact or loose, somewhat fastigiate cyme. The corolla is showy, dark purple, tubular, twice as long as the involucre. Involucre smooth, ovoid-campanulate; scales appressed, all but the lowest rounded and obtuse, without appendage. History.—Ironweed is a very common plant in the Western States, growing in the woods and prairies, and along river-streams, and flower- ing from July to September. The root, which is the part used, is bitter, and imparts its properties to water or alcohol. The Vernonia Novebora- censis, growing in the Eastern, Western, and Middle States, and its variety V. Praealta, hearing purple flowers, and the V. Tomentosa, with some other species, possess similar medicinal properties. Properties and Uses. — Ironweed is a bitter tonic, deobstruent, and alterative. In powder or decoction, the root is beneficial in amenorrhea, dysmenorrhea, leucorrhea, and menorrhagia. In intermittent, remittent, and bilious fevers, the decoction or a saturated tincture has been recom- mended. Said to have been useful in scrofula, and some cutaneous diseases. Dose of the decoction, one or two fluidounces ; of the tincture, one or two fluidrachms. The leaves or powdered root in the form of poultice make an excellent discutient application to tumors.

Agrestis, and V. Pere- grina, possesses somewhat similar properties. They all impart their virtues to water. Properties and Uses. — Speedwell is tonic, expectorant, diaphoretic, and diuretic. It was formerly administered in pectoral and nephritic complaints, diseases of the skin, icterus, and in the treatment of wounds. Likewise reputed beneficial in scrofula, and other diseases where altera- tives are indicated, especially the V. Peregrina; to be given internally, and used as a wash. The V. Beccabunga is antiscorbutic, diuretic, febrifuge, and emmenagogue, and said to be beneficial in cases of obstructed menstruation, scurvy, fevers, and coughs. The decoction of the plants may be used freely. VIBURNUM OPULUS. High Cranberry. Nat. Ord.—Caprifoliaceaa. Sex. Syst.—Pentandria Trigynia. THE BARK. Description.—This is the Viburnum Oxycoccus of Pursh; it is a nearly smooth and upright shrub or small tree, rising from five to twelve feet in hight; the stems are several from the same root, branched above. The leaves are three-lobed, three-veined, broadly wedge-shaped or trun- cate at base, broader than long ; the lobes divaricate, acuminate, crenate- ly-toothed on the sides, entire in the sinuses; the petioles have two or more glands at the base, and are channeled above. The flowers are white or reddish-white, and are disposed in rayed, pedunculated cymes; the marginal flowers are large and sterile, the inner flowers much smaller and fertile. The fruit is ovoid, red, very acid, ripens late, and remains upon the bush after the leaves have fallen; it resembles the common cranberry, and is sometimes substituted for it. The V. Roseum, Snow- ball, or Guelder-rosetree, is a cultivated European variety, with the whole cyme turned into large sterile flowers. History.—This is a handsome indigenous shrub, growing in low rich lands, woods, and borders of fields, in the northern part of the United States and Canada, flowering in June, and presenting at this time a very showy appearance. The flowers are succeeded by red and very acid berries, resembling low cranberries, and which remain through the win- ter. The bark is the officinal part; as met with in the shops, it is in 958 Materia Medica. thin, longitudinally curved pieces, from one-fourth of an inch to two or three inches in length, and from two to six lines in width, with a dark- grayish epidermis, and whitish-yellow, or reddish-yellow internal integ- ument ; it has no smell, and a peculiar, not unpleasant, bitterish and astringent taste. It is frequently put up by the Shakers, when it is somewhat flattened from pressure. It yields its properties to water or diluted alcohol. The Pharmaceutical Institute of the city of New York, profess to have obtained the active principle of this plant, which they have called Viburine. I have not been able to learn its mode of prepara- tion, nor have I seen any of it, and therefore cannot recommend it. There is a great disposition among some of the manufacturers of our concen- trated remedies to keep their processes secret; this is very reprehen- sible, and the maxim cannot be too frequently repeated—" Never use a prepared remedy unless its mode of preparation is made known"—to do differently savors of charlatanism. Beside, great imposition may be practiced upon physicians by designing and speculating individuals. Properties and Uses.—High-Cranberry-bark is a powerful antispas- modic, and in consequence of this property, it is more generally known among Eclectic practitioners by the name of Cramp Bark. It is very effective in relaxing cramps and spasms of all kinds, as asthma, hyste- ria, cramps of the limbs or other parts in females, especially during pregnancy, and it is said to be highly beneficial to those who are subject to convulsions during pregnancy, or at the time of parturition, prevent- ing the attacks entirely, if used daily for the last twro or three months of gestation. The following, forms an excellent preparation for the relief of spasmodic attacks, viz : Take of Cramp Bark two ounces, Scullcap, Skunkcabbage, of each one ounce, Cloves half an ounce, Cap- sicum two drachms. Have all in powder, coarsely bruised, and add to them tAvo quarts of good sherry or native wine. Dose, one or two fluidounces, two or three times a day. Dose of the decoction, or vinous tincture of Cramp Bark, two fluidounces, two or three times a day. It may be proper to remark here that I have found a poultice of low cran- berries very efficacious in indolent and malignant ulcers ; and applied round the throat in the inflammation and swelling attending scarlatina- maligna, and other diseases, it gives prompt and marked relief. Pro- bably, the High-Cranberries will effect the same results. (See Cata- plasma Oxycocci.) Viburnum Dentatum, Arrow-wood, or Mealy-tree, called by the former name on account of its long, straight, slender branches or young shoots, is a somewhat smooth shrub, from six to twelve feet in hight, growing in low grounds, damp woods and thickets, throughout the United States, with roundish-ovate, dentate-serrate, furrow-plaited leaves, on long, slender petioles. The leaves are two or three inches in diame ter, the upper pair oval, the veins beneath prominent, parallel, and Viburnum Prunifolium. 959 pubescent in their axils. The flowers are white, in pedunculate cymes, and appear in June. The fruit consists of small ovoid-globose, dark- blue berries. The bark of this tree is ash-colored, and is employed as a diuretic and detergent, and has been highly recommended as an internal and external agent to cure cancer ; the infusion to be used freely. It cer- tainly deserves the attention of the profession in their treatment of this formidable disease. It may also be used in extract, pills, or plaster. Off.

Description.—This shrub or tree, also known by the name of Sloe, is indigenous to this country, growing to the hight of from ten to twenty feet. The branches are spreading, some of them often stinted and naked, giving the plant an unthrifty aspect. The leaves are about two inches long, and nearly as wide, roundish-ovate, smooth, shining above, obtuse at both ends, acutely serrate, with uncinate teeth, and situated on short petioles, slightly margined with straight, narrow wings. The flowen are white, in large, terminal, and sessile cymes. The fruit consists of OAroid-oblong, sweet, edible, blackish berries. History.—This tree is found throughout the United States, being most abundant in the Middle and Southern States. It floAvers from March to June, and presents at this time a very handsome appearance. It is usually found in woods and thickets. The bark of the roots, stem, and branches are medicinal, but that of the root is preferred. It is fawn- colored externally, with a feeble odor, and a very bitter, slightly aroma- tic taste. Water or alcohol extracts its properties. It is readily pulver- ized when dry, and affords a reddish-colored poAvder tinged with gray. It is said to contain extractive matter, gum, tannin, gallic acid, and a peculiar resinous principle, for which the name of Viburnin has been proposed. It is obtained by the usual process for separating the resinous principles from plants, and is a light reddish-brown powder, intensely bitter, possessing the properties of the bark in a concentrated form. Properties and Uses. —Black Haw is tonic, astringent, diuretic, and alterative ; the decoction has been used as a gargle in aphthae, as a wash to indolent ulcers, and ophthalmic affections ; and internally in chronic diarrhea, dysentery, and palpitation of the heart. It appears to exert an especial tonic influence upon the uterus, and is highly recommended 960 Materia Medica. in cases of threatened abortion, and as a preventive in cases of habitual miscarriage ; in the latter case its use should commence a week or two previous to the aborting period, and be continued through the remaining period of pregnancy. It has also proved useful in relieving severe after- pains. The infusion may be given in half fluidounce doses, several times a day; or the tincture, in doses of a fluidrachm, four or five times a day. The powder may be given in half drachm, or drachm doses. VIOLA PEDATA. Blue Violet. Nat. Ord.—Violaceaa. Sex. Syst.—Pentandria Monogynia. THE WHOLE PLANT. Description.—Blue-Violet, or as it is sometimes called, Bird's-foot Violet, is an indigenous, stemless plant, glabrous, with the leaves and scapes all from perennial, fleshy, premorse, subterranean rootstocks. The leaves are pedately five to nine-parted ; the lobes being linear-lan- ceolate, obtuse, and nearly entire. Petioles with long, ciliate stipules at base. The flowers are large, very showy, an inch broad, pale or deep lilac-purple, and fragrant. Peduncles somewhat four-sided, much longer than the leaves. The divisions of the calyx are linear, acute-ciliate, emarginate behind. Petals veinless, entire, and beardless. Spur or beak obscure. The stigma is large, compressed M the sides, obliquely truncate, and perforate at the apex. History.—This plant is common to the United States, growing from New England to Carolina, and west to Missouri, in dry sandy fields and rocky woods, flowering in May and June. The herb and root are used, and impart their virtues to water. The Viola Odorata or Sweet Violet of Europe, is much cultivated in this country on account of its beautiful flowers, which appear in April and May. It is a small, pretty, creeping plant, the runners of which are furnished with fibrous roots, and send up annually tufts of leaves and flowers. The leaves are cordate, crenate, nearly smooth, and sup- ported on long petioles. The flowers are small and fragrant, at the sum- mit of delicate, quadrangular, channeled, bracted, radical peduncles. The stipules are lanceolate and toothed. The petals are obovate, obtuse, unequal, bluish-purple, or deep violet color, except at the claws, which are whitish, and longer than the obtuse, ovate sepals. The two lateral petals are spreading, with a hairy line toward the base, the inferior furn- ished with a large blunt spur, and the two upper reflected. The stamens are in the center with very short filaments, and anthers slightly cohering by an orange-colored membranous expansion. Stigma hooked, naked ; capsules turgid, hairy ; seeds turbinate, pallid. Viscum Flavescens. 961 The flowers of this species have a very slightly bitter taste, and a peculiar, agreeable odor, which, however, occasions faintness and giddi- ness with some persons. Their odor is lost by drying. They should be gathered before being fully blown, deprived of their calyx, and rapidly dried in a heated room. An infusion of them affords a very delicate test for acids and alkalies, the former changing it to red, the latter to green. Three or four drachms of the seeds, made into an emulsion with sugar and water, act as a mild and pleasant purgative. The roots are emetic and purgative, but are very uncertain in their action. A peculiar alkaline principle has been detected in this plant, called Violia, it bears some resemblance to Emetia. It is probably contained in other species of Viola. Properties and Uses. — Blue Violet is mucilaginous, emollient, and slightly laxative; also antisyphilitic, and forms a valuable remedy for this disease, when combined with Corydallis Formosa. Has been used in pectoral, nephritic, and cutaneous affections, especially crusta lactea. The plant should be used when fresh, as drying destroys its active pro- perties. The seeds of the European sweet violet, Viola Odorata, have been used in graArel, and for similar purposes as the V. Pedata. The V. Tricolor, or pansy, may be used as a substitute. The roots of these plants are bitterish and slightly acrid, and in doses of from eight to ten grains are tonic; from twenty-five to thirty grains, purgative; and from forty to sixty grains, emetic. The Viola. Ovata, or rattlesnake violet, has been highly recommended in the bites of rattlesnakes, the infusion to be freely administered; and the infusion used internally, Avith a fomentation of the leaves locally applied, have proved efficacious in obstinate chronic ophthalmia; a simi- lar course is reputed very valuable in scrofulous diseases. Probably all the species possess analogous properties; they are undoubtedly more active agents than generally supposed, and deserve further investigation. VISCUM FLAVESCENS. Mistletoe. Nat. Ord.—Loranthaceaa. Sex. Syst.—Dioacia Tetrandria. the leaves. Description.—This is the Viscum Verticillatum of Nuttall, and Viscum Album of Walter; it is a yelloAvish-green, succulent parasite, growing on the branches and trunks of old trees, especially elms, oaks, hicko- ries, etc. The stems are jointed, an inch or an inch and a half in length, rather thick, with many round, spreading, opposite, and sometimes ver- ticillate, terete branches. The leaves are opposite, cuneate-obovate, three-veined, obtuse, smooth, entire, contracted at the base into a short petiole, and from nine to sixteen lines long, by from four to nine broad. 61 962 Materia Medica. The flowers are small, greenish-white, sterile ones mostly three-parted, and arranged in axillary, solitary spikes, about as long as the leaves. Fruit globose, yellowish-Avhite, smooth, semi-transparent, with a viscous pulp, in clusters, and contain one fleshy seed; they remain throughout the winter. History.—This parasitic shrub is found growing on various trees; but that which is found on the oak is preferred. The bark and leaves have a peculiar disagreeable odor, and a nauseous, sweetish, slightly bitter taste. The proper time for collection is in November, when it should be gradually dried, pulverized, and kept in a well-stopped bottle. It should never be kept more than a year, as age impairs its active quali- ties. The mistletoe growing on the water or black elm ( Ulmus Nemo- ralis), and on the water-oak ( Quercus Aquatica), is reputed to possess the most energetic medicinal virtues. Properties and Uses.—Narcotic, antispasmodic, and tonic. Has been found beneficial in epilepsy, insanity, paralysis, and other nervous dis- eases. In using this agent it is always necessary to regulate the condi- tion of the stomach and boAvels, and the menstrual discharge, and other faulty secretions, and remove worms, if any are present, previous to its exhibition. It may be given in doses of from thirty to sixty grains, and gradually increased to three or four drachms, three or four times a day, and if it produces sleep or other narcotic effects, the doses must be diminished. This plant is by no means inert, and its failures in the hands of some practitioners must be attributed to the want of proper doses, or to the employment of an article which age or exposure to the air had injured. The powder is best given in an infusion of valerian. VITIS VINIFERA. The Grape. Nat. Ord.—Vitaceaa. Sex. Syst.—Pentandria Monogynia. the fruit, and its fermented juice. Description.—The Grapevine is well known nearly all over the globe; yet it is so variable in its character that no description will apply to all the kinds. The leaves are more or less lobed, sinuated, smooth, pubes- cent, downy, or naked; are flat, crisped, or even plaited, and either of a pale-green or dark-green color. The branches may be prostrate, climbing, or erect, and tender or hard; the racemes or bunches are loose or compact, ovate or cylindrical. The fruit or berries are red, yellow, purple, white, or pale; globose, ovate, or oblong in form; and sweet, murky, or austere in taste. The seeds are variable in number, and sometimes by abortion are wholly wanting. History. — The Grapevine grows wild in the south of Asia and in Greece, and was, probably, first cultivated in the East, but at what period, it is impossible to say; it must have been known to the antedilu- VlTIS VlNIFERA. 963 vian world, as we are told in Scripture, that Noah, after leaving the ark, planted a vineyard, and drank of the wine. At present it is cultivated in the warm temperate climates of Europe and America. The leaves and tendrils are somewhat astringent, and were formerly employed in diarrhea, hemorrhages, and other morbid discharges. The juice of the stem has also had medicinal virtues attributed to it, and is often added at the present day to washes for improving the hair and removing bald- ness. The juice of the unripe fruit is called Verjuice, and contains malic, citric, tartaric, and racemic acids, with bitartrate of potassa, sul- phates of potassa and lime, a little tannic acid, etc. The juice of the ripe fruit is called Must, and contains sugar, gum, malic acid, bitartrate of potassa, various inorganic salts, etc.: when fermented it is called Wine. So long as the ripe grape remains entire, it undergoes little change beyond gradual desiccation and a conversion of its acid into sugar; but if the grape be crushed, or its juice expressed, and the tem- perature maintained at between 60° and 70°, fermentation ensues through the action of the air, and of the insoluble glutenoid principle existing in the husk, which acts the same part as that of yeast in the fermentation of malt or solutions of sugar. The consequence is, the must becomes warmer, the sugar gradually disappears and carbonic acid escapes, which causes a head—the name given to the more solid parts which are thrown to the surface in a hemispherical mass of froth; alco- hol is now formed, changing the liquor from a sweet to the vinous flavor, and if the grapes were red, the liquor assumes a deep-red color. After a while the fermentation slackens, when it becomes necessary to acce- lerate it by thoroughly mixing the contents of the vat. When the juice contains too large a proportion of sugar, some tartar is added to it, and where the saccharine matter is deficient, sugar is added. When the liquor has acquired a strong vinous taste, and becomes perfectly clear, the wine is considered formed, and is racked off into casks; but even at this stage of the process, the fermentation continues for several months longer; during which period, a frothy matter is formed, which for the first few days collects round the bung, but afterward precipitates along with coloring matter and tartar, forming a deposit which constitutes the Wine Lees. Climate, soil, and many other circumstances, have much influence upon the quality of the wine ; and during its preparation, not only does it require different treatment, according to the character of the wine, but it also requires great care, attention, and practical skill to manage the fermentation properly. Wines are divided into the Red and White, according to their color ; and according to their taste and other qualities, are either spirituous, sweet, dry, light, sparkling, still, rough or acidulated. Red wines are prepared from the must of black grapes, fermented with their husks; White wines, from white grapes, or from the juice of black grapes 964 Materia Medica. fermented apart from their husks. When the process of fermentation is arrested at an early stage, while a considerable part of the sugar remains unaltered, Sweet wines are formed. When the wines are bottled before the fermentation is fully completed, the process continuing gradually in the bottle, impregnating the liquor with the carbonic acid which is gen- erated and cannot escape, it renders it effervescent, forming the Spark- ling wines. When from the presence of a large proportion of saccharine matter, fermentation proceeds until checked by the alcohol produced, generous or Spirituous wines are the result. When the sugar and fer- ment are in considerable amount, and in the proper relative proportions for mutual decomposition, the wine will be strong-bodied and sound, without any sweetness or acidity, and is called Dry. The Still wines are those in which fermentation proceeds, until the greater part of the sugar has disappeared ; they do not effervesce. Light wines are those in which only a small proportion of saccharine matter exists in the grape-juice, and consequently a small amount only of alcohol is generated. The Rough or Astringent wines owe their flavor to a portion of tannic acid derived from the husks of the grape, and the Acidulous and Sparkling wines to the presence of carbonic acid, or in the former instance to an unusual proportion of tartar. Wines are manufactured in many coun- tries, and are known by various names, according to their source. Those most usually employed in medicine are Port, Sherry, Claret, Madeira, and Malaga wines. Port wine is of a deep purple color, and when recent is rough, strong and slightly sweet; it is the strongest of wines in common use; when too long kept it becomes deteriorated. Considerable quantities of brandy are generally added to it, which causes its heating quality on the palate. Sherry is of a deep-amber color, and when good possesses a dry, aro- matic flavor and fragrancy, without any acidity; it ranks among the stronger white wines, and is indicated in this country and England as the officinal wine. Claret is a red wine, and ranks as a light wine; it has a deep purple color, and when good, a delicate taste, in which the vinous flavor is blended with slight acidity and astringency. The most esteemed kinds are the Medoc clarets, called Chateau-Lafite, Chateau-Margaux, Chdteau- Latour, and Chdteau-Haut Br ion. Madeira is the strongest white wine in general use. It is a slightly acid wine, and when of proper age and in good condition, has a rich, nutty, aromatic flavor. All these wines, are, however, much subject to adulteration, and some care must be taken, in order to obtain a pure article. The intoxicating ingredient in all Avines is the alcohol which they contain ; and hence their relative strength depends upon the quantity VlTIS VlNIFERA. 965 of this substance entering into their composition. The alcohol, however, naturally in wine, is so blended with its other constituents as to be in a modified state, which renders it less intoxicating and less injurious than the same quantity of alcohol separated by distillation and diluted with water. Mr. Brande has published a very interesting table, giving the per centage by measure of alcohol of sp. gr. 0.825 in different kinds of wine.

The native Catawba grape, introduced to public notice by Major Adlum, of Washington city, is a superior wine grape, producing a most excel- lent wine, Avhich will undoubtedly supersede the use of all foreign Avines, at least, for medical and pharmaceutical uses. Mr. N. Longworth, of Cincinnati, has been for a long time engaged in the cultivation of this and other kinds of grapes, as well as in the manufacturing of native wines, and by dint of perseverance and careful investigation has succeeded in preparing wines which are fully equal to those of foreign origin. Long- worth's Catawba, and Sparkling Catawba, are becoming known through- out the country as superior articles, and their purity and freedom from adulterations render them preferable in all instances where these agents are indicated or required. Wines consist chiefly of water and alcohol, with grape-sugar, gum, extractive, coloring matter, tannic, malic, and carbonic acids, bitartrate of potassa, tartrate of lime, volatile oil, and cenanthic ether. The pre- sence of these constituents varies according to the kind of wine, a part being absent in some and present in others; thus sugar is present in sweet wines, tannic acid in rough wines, and carbonic acid in the spark- ling varieties. Many of the imported wines are subject to adulteration, some of which it is difficult to detect. The addition of lead may be ascertained by the black precipitate occasioned on testing the wine with sulphureted hydrogen; the presence of lime by the large amount of precipitate occasioned by the addition of a solution of oxalate of ammonia. Many counterfeit or spurious Avines are also prepared, some of which are decid- edly injurious in their effects upon the stomach, and when relied upon as therapeutic agents, always produce mischief and disappointment. Port is frequently imitated with a mixture of real port, cider, juice of elder-berries, brandy, logwood and alum. Madeira is likewise frequently met with of a spurious character. Champagne is seldom met with in this country, unless it be an imitation, hence, the great preference given all over the country to Longworth's Sparkling Catawba, which is fully equal to the imported Champagne. An excellent imitation of Champagne wine is made as follows: Take of good cider, (crab-apple cider is the best), twenty-eight gallons; fourth-proof brandy one gallon; genuine Champagne wine five gallons; milk one pint, bitartrate of potassa, half a pound. These are mixed together, allowed to stand for a time, and bottled while fermenting. When quite ripe, the grape is a most pleasant and grateful fruit, and on account of its refreshing properties, is admirably adapted to febrile complaints; in large quantities it is diuretic and gently laxative, but eaten moderately will be found beneficial to those disposed to diarrhea or dysentery ; it is also useful in many instances of acid stomach. Grapes are also dried in several ways ; the most esteemed is to partially cut the stalks of the bunches before the grapes are perfectly ripe, and allow VlTIS VlNIFERA. 967 them to dry upon the vine; or, they may be picked when properly ma- tured, steeped for a short time in an alkaline ley, and then dried. Dried grapes are the raisins (uva passa) of commerce, of which there are several varieties, the Malaga, Smyrna, and Corinthian raisins or currants, as they are commonly called in this country, of which the first named is considered the best. The raisins of commerce are prepared from the grapes of the Mediterranean countries. They contain more sugar than grapes, as may often be seen by its efflorescence on the surface of the raisins or its concretion in small masses within their substance. Grape- sugar is not so sweet as cane-sugar, is less soluble in cold water, is more soluble in cold alcohol, forms a syrup of less viscidity, and is identical with sugar of starch. Properties and Uses.—Wine is consumed in most civilized countries; but in a state of health it is at least useless, if not absolutely pernicious. The degree of mischief which it produces, depends very much on the character of the Avine. Thus the light wines of France are compara- tively innocuous; Avhile the habitual use of the stronger ones, such as port, madeira, sherry, etc., even though taken in moderation, is always injurious, as having a tendency to induce gout and apoplexy, and other diseases dependent on plethora and over-stimulation. All wines, how- ever, when used habitually in excess, are productive of bad conse- quences. They weaken the stomach, produce diseases of the liver, and give rise to dropsy, gout, apoplexy, tremors, and not unfrequently mania. Nevertheless, Avine is an important medicine, productive of the best effects in certain diseases and states of the system. As an article of the Materia Medica, it ranks as a stimulant and antispasmodic. In the con- valescence from protracted fever, and in sinking of the vital powers, it is frequently the best remedy that can be employed. In certain stages of typhoid fevers, and in extensive ulceration and gangrene, this remedy, either alone, or conjoined Avith bark or opium, is often our main depend- ence. In Ioav febrile affections, if it increase the fullness and lessen the frequency of the pulse, mitigate delirium, and produce a tendency to sleep, its further use may be deemed proper ; but on the contrary, if it render the pulse quicker, augment the heat and thirst, produce restless- ness, or increase delirium, it should be immediately laid aside as inju- rious. In some convulsive diseases, as for example tetanus, wine, liberally given, has been found useful. Wine, when used medicinally, should be sound, and good of its kind; for otherwise it will disagree with the stomach, and prove rather detri- mental than useful. The individual Avine selected for internal exhibition must be determined by the nature of the disease, and the particular object in vieAV. Teneriffe is a good variety of white wine for medicinal use, being of about a medium strength, and agreeing very well with most stomachs. Sherry, when in good condition, is also a fine wine, and, being free from all acid, is to be preferred whenever the stomach is 968 Materia Medica. delicate, or has a tendency to dyspeptic acidity. Unfortunately, how ever, it is of very unequal quality. Good Madeira is the most generous of the white wines, particularly adapted to the purpose of resuscitating debilitated constitutions, and of sustaining the sinking energies of the system in old age. The slight acidity, however, of pure Madeira causes it to disagree with some stomachs, and renders it an improper wine for gouty persons. Port is generally used in cases of pure debility, espe- cially when attended with a loose state of the bowels, unaccompanied by inflammation. In such cases, it often acts as a powerful tonic as well as stimulant, giving increased activity to all the functions, especially diges- tion. Claret is much less heating, and is often useful on account of its aperient and diuretic qualities. All the acid and acidulous wines are contra-indicated in the gouty and uric acid diathesis, as they are very apt to convert the existing pre- disposition into disease. They are useful; however, in what is called the phosphatic diathesis, their acidity tending to prevent the deposition of the earthy phosphates. The quantity of wine which may be given with advantage in disease, is necessarily very variable. In Ioav fevers, it may be administered to the extent of a bottle or more in twenty-four hours, either pure, or in the form of wine-whey. This is made by adding from a gill to half a pint of wine to a pint of boiling milk, straining without pressure to sepa- rate the curd which is formed, and sweetening the clear whey with loaf- sugar. Wine-Avhey forms a peculiarly safe and grateful stimulus in typhoid fevers and other febrile affections, which, after depletion, may tend to a state of deficient action and be accompanied with a dry skin. Under these circumstances, it often acts as a diaphoretic, and, if used of moderate strength, without stimulating the system in any marked degree.— U. S. Disp. Wine is employed as a menstruum to extract the virtues of several plants, and the preparations thus formed are called Vinous tinctures or Medicated wines. The chief medical use of raisins is to flavor demulcent beverages; taken in substance they are gently laxative, but are also flatulent and difficult of digestion, and when largely eaten sometimes produce un- pleasant effects, especially in children. An excellent, pure, and spark- ling wine may be made as follows : Take twelve pounds of good raisins, cut each raisin in two, and put them into a five gallon demijohn, nearly filled with clean soft water; let it stand uncorked for about fourteen days, then filter, bottle, and cork well. Upon the residue, after the wine is poured off, put as much water as before, let it stand a sufficient time, and the result will be a good white wine vinegar. Xanthorrhiza Apiifolia. 969 XANTHORRHIZA APIIFOLIA. Yellowroot. Nat. Ord.—Ranunculaceae. Sex. Syst.—Pentandria Polygynia. the root. Description.—This is an indigenous shrub, two or three feet in hight, with a thick horizontal root, throwing up numerous suckers. The stem is short, woody, leafy above, with a smooth bark, and bright yellow wood. The leaves, Avhich stand thickly at the upper part of the stem, are pinnate, about eight inches long, including the long petioles, which em- brace the stem at their base, glabrous, consisting of about three pairs of leaflets with an odd one ; the leaflets are two or three inches long, ovate or rhomboidal, lanceolate, acute, sessile, incisely lobed and dentate. The fiowers are small, dark-purple, and arranged in long, drooping, divided, and axillary racemes; they are also many, and appear with the leaves. The petals are obovate, two-lobed ; the ovaries from five to nine. Folli- cles or capsules spreading, a line and a half long, inflated, compressed, one-celled, two-valved, opening at the apex; seeds oval, flattened. History.—This is a native of the Southern States, being principally restricted to the mountains ; it is likewise abundant in some of the West- ern States, and along the lower parts of the Ohio. It flowers in March and April. The root is the part directed to be used ; it is from three inches to a foot in length, about half an inch in thickness, of a yellow color, and of a simple, but extremely bitter taste. It imparts its virtues to water, and the infusion is not affected by a solution of the sulphate of iron. The bark of the stem is equally as efficacious as the root. It was well known to the Indians on account of its tinctorial properties; it imparts a drab color to wool, and a rich yellow to silk, but is said to have no effect on cotton or linen. With Prussian blue it affords a dull olive green. Properties and Uses.—Yellow root is a pure, bitter tonic ; considered by the late Professor Barton to be superior to Colombo. It may be used for all purposes in which the other simple tonic bitters are applicable. It may be given in decoction, tincture, or powder; two scruples of the powder agree well with the stomach. From the intensely bitter char- acter of the resin, alcohol would appear to be the best menstruum. XANTHOXYLUM FRAXINEUM. Prickly Ash. Nat. Ord.—Xanthoxylacea?. Sex. Syst.—Dioecia Pentandria. THE BARK AND BERRIES. Description.—This shrub is the Xanthoxylum Americanum of Miller, the X. Fraxinifolium of Marshall, the X. Ramifiorum of Michaux, and 970 Materia Medica. the X. Tricarpum of Hooker. It is known by the various names of Northern Prickly Ash, Toothache-bush, Yellow-wood, etc. It is an indi- genous shrub, ten or twelve feet in hight, with alternate branches, which are covered with strong, conical, brown prickles, Avith a broad base, scattered irregularly, though most frequently in pairs at the insertion of the young branches. The leaves are alternate and pinnate; the leaflets about five pairs with an odd one, nearly sessile, ovate, acute, with slight vesicular serratures, somewhat doAvny underneath. The common petiole is round, usually prickly on the back, and sometimes unarmed. The flowers are in small, dense, sessile umbels, near the origin of the young branches, they are small, greenish, dicecious or polygamous, appear before the leaves, and have a somewhat aromatic odor. In the sterile flower the calyx is five-leaved, with oblong, obtuse, erect segments, five stamens with subulate filaments, and sagittate, four-celled anthers ; the ovary is abortive. In the hermaphrodite or perfect floAver, the calyx and stamens are like the last, ovaries three or four, pedicelled, Avith erect, converging styles nearly as long as the stamens. The fertile or female floAvers grow upon a separate tree, are apetalous, with a smaller and more compressed calyx, and five pedicelled ovaries, with styles converg- ing into close contact at top, and a little twisted ; stigmas obtuse. Each fruitful flower is followed by as many capsules as it had ovaries. The capsules are stipitate, oval, covered with excavated dots, varying from green to red, two valved, and one-seeded ; seeds oval and blackish. History.—The Prickly Ash is a native of North America, groAving from Canada to Virginia, and West to the Mississippi, in woods, thickets, and moist shady places, and flowering in April and May before the appearance of the leaves. The whole plant is endowed with active qualities; the leaves and fruit abound in a fragrant, volatile oil, some- what resembling in odor that of lemons ; and the bark is acrid, pungent, and aromatic. Both the bark and fruit (berries) are officinal. As found in the shops, the bark is in quilled fragments, a line or two in thickness, with a grayish-white epidermis, which is frequently removed, internally of a whitish color, and somewhat shining; that from the small branches is beset with prickles. It is light, brittle, with a somewhat amylaceous fracture, and when dry nearly inodorous, having a taste at first sweetish and aromatic, but ultimately bitterish and acrid. It yields its properties to boiling water or alcohol. The fruit or berries as met with in the shops, consists of an open, bivalved, oval capsule, about three lines in length and two in diameter, brownish and covered Avith excavated dots externally, whitish-yellow, and smooth internally, and usually with a portion of the stalk appended ; they inclose an oval, shining, black, wrinkled seed, which in the dried state is hollow, and grayish-yellow, or light brownish-yellow internally, inodorous, very brittle, and having the peculiar taste of the capsule in a very faint degree; this seed is more often absent than present in the capsule, from whose Xanthoxylum Fraxineum. 971 opening it escapes, and may be generally found separated from it, but mixed up with the mass. The medicinal virtues of the fruit reside in the capsules, which have a faintly aromatic, peculiar odor, and a warm, pungent, peculiar, aromatic, and pleasant taste, both of which properties are more energetic in the recent than in the dried fruit. They depend upon a volatile oil for their properties, which they yield to alcohol or ether. The bark has been analyzed by Dr. Staples, who found it to consist of a volatile oil, a greenish fixed oil, resin, gum, coloring matter, and a peculiar crystallizable principle which he calls Xanthoxyline, but the properties of which are not yet determined. Mr. W. S. Merrell has prepared an oil from the berries, which he calls Oil of Xanthoxylum; it is obtained by macerating the bruised berries in alcohol or ether, filtering, and evaporating. That made by the agency of alcohol is the most turbid and probably contains resin and extractive. It is of a dark-brown color, of a faint, peculiar odor, and of the taste peculiar to the berries in a high degree of concentration, being aromatic, and very warm and pungent. One pound of the berries yields about four fluidounces of the oil; and one fluidounce of this to thirty-two fluidounces of alcohol makes a good strong tincture, equal to one made by macerating two ounces of the berries in a pint of alcohol. Mr. J. B. Robinson of this city has prepared an ethereal oil from Prickly Ash Bark; he makes a tincture with ether, filters, and then eva- porates or distils off the ether. Four pounds of the bark thus treated yield one pound of oil. The oil made by Mr. Robinson is dark green- ish-black in bulk, yellowish-green in thin layers, very fluid, possessing an odor of ether, and the peculiar taste of the bark in an eminent degree. It is soluble in alcohol, ether, and alkaline solutions, and will probably be found to possess the active principle of the bark in a concentrated form. Properties and Uses.— Prickly Ash Bark is stimulant, tonic, altera- tive, and sialogogue. When swallowed, it produces a sense of heat in the stomach, with more or less arterial excitement, and a tendency to diaphoresis. It is used as a stimulant in languid states of the system, and as a sialogogue in paralysis of the tongue and mouth. It has proved highly beneficial in chronic rheumatism, colic, syphilis, hepatic derange- ments, and wherever a stimulating alterative treatment is required. Combined with equal parts of pulverized blueflag and mandrake, it will bring on salivation, and is useful on this account in the treatment of scrofulous, syphilitic and other diseases, where there is a want of sus- ceptibility to the influence of other alterative agents ; the mixture must be given in small doses, and repeated at short intervals. Externally, it forms an excellent stimulating application to indolent and malignant ulcers. Dose of the powder, from ten to thirty grains, three times a day. Prickly Ash Berries are stimulant, carminative, and antispasmodic, acting especially on mucous tissues. Combined with pokeberries, in the 972 Materia Medica. form of tincture, they are invaluable in chronic rheumatism, and tertiary syphilis. The tincture is also useful in all nervous diseases, spasms of the bowels, flatulency, and in diarrhea. In tympanitic distension of the bowels, during peritoneal inflammation, it is a safe and superior remedy, used internally and as an injection ; half a fluidrachm to a fluidrachm, internally, every hour or two in sweetened water—and half a fluidounce of the tincture, with occasionally ten or twenty drops of laudanum added, according to the symptoms, given by enema every fifteen or thirty minutes. In Asiatic cholera, it was extensively used by the Eclectic physicians of Cincinnati, and with great success — it acted like electri- city, so sudden was its influence over the system; indeed, many patients likened its action to an electric shock, which seemed to diffuse itself throughout the whole frame. We gave it in teaspoonful doses, slightly diluted, and repeated, according to circumstances, every five, ten or fifteen minutes, with an injection, prepared as above-mentioned, which was given immediately after each discharge from the bowels, and retained by the patient as long as possible. This is one of our most valuable agents. The dose of the tincture of the berries, as a carminative and antispasmodic, is from ten to thirty drops, three or four times a day. Used by some, during the intermissions, as a remedy in intermittent fever, which it is said to remove speedily. There is a material difference, in their influence on the system, between the tincture of the bark, or that of the berries, which should always be had in view. A patient with cholerine came very near losing life, in consequence of using the tincture of the bark, instead of the berries, as prescribed ; the druggist who filled the prescription supposed the properties of each were similar, and that they could be safely substituted the one for the other. The oil of xan- thoxylum may be used for the same purposes as the berries, in doses of from two to ten drops in mucilage, or on sugar; and its tincture, made according to the formula above, may be administered in the same doses as the tincture of the berries. The Aralia Spinosa is frequently but erroneously called by the name of Southern Prickly Ash ; it differs from the xanthoxylum in its botanical character, as Avell as in its medicinal virtues. Mr. W. S. Merrell, has been for some time engaged in the investigation of the true character of these plants, and he informs me that he is confident that the agent Avhich was employed during the cholera, and has been used since, as the Aralia Spinosa, is really a Xanthoxylum. It is to be regretted that so much confusion should exist in relation to the identity of some of our valuable agents, and Avhich is principally owing to the similarity of vulgar names among different plants, and an inattention to their systematic names and characters. We hope that the above doubt may be satisfactorily solved by those having the proper opportunities to effect it. Off. Prep.—Enema Xanthoxyli; Extractum Xanthoxyli Fluidum ; Tinctura Laricis Composita ; Tinctura Xanthoxyli. Xanthoxylin. 973 XANTHOXYLIN. Xanthoxylin. the oleo-resinous principle of prickly ash bark. Preparation.—Prepare a saturated tincture of Prickly Ash Bark, filter, distil ofl' the alcohol, and to the residue add water,—the oleo-resin precipitates to the bottom. After precipitation has ceased, collect the oleo-resin, and wash it in clear water; allow it to subside, and then separate it from the water. History.—The profession are indebted to Mr. W. S. Merrell for the preparation of this valuable agent, which possesses all the medicinal properties of the bark in a concentrated form. When in mass it is blackish, but of a reddish-brown color in thin layers; it has a peculiar odor, somewhat similar to that of most oleo-resins, and a peculiar, bitter- ish taste, quickly succeeded by a persistent pungency in the mouth and fauces. It is insoluble in water ; partially soluble in aqua ammonia and liquor potassa, forming a solution with a soapy feeling; soluble in ether, from which aqua ammonia removes a portion without much change of color; soluble in oil of turpentine, and to a greater or less extent in oil of savin, and some other essential oils ; and soluble in alcohol, from which water precipitates it, forming a dirty-Avhite solution. Acetic, nitric, sulphuric, and muriatic acids, when added to the alcoholic solu- tion, occasion no precipitate. Properties and Uses.—Xanthoxylin is stimulant, tonic, alterative and sialogogue, and may be used in all cases where it is desired to stimulate and strengthen mucous tissues. It forms an excellent remedy for rheu- matism unaccompanied with inflammation, or where there is an asthenic condition of the system, and I have often used it for this purpose with cimicifugin, in doses of one grain of each, every one, two, or three hours, with much advantage. Combined with quinia, it will be found very beneficial in cases where quinia alone appears to exert no influ- ence, and will prove a valuable agent in dyspepsia, accompanied with want of appetite, flatulence, and distress after eating, given in conjunc- tion with ptelein. In low typhoid fever, Xanthoxylin will be found a valuable and permanent stimulating tonic, and may, Avhen necessary, be added to laxatives, in that disease, to prevent too much prostration—it must, however, be employed only during the stage of prostration. It may be used alone as a stimulating ijjbnic and alterative. Where a stim- ulating tonic is required for children after diarrhea, dysentery, or other debilitating diseases, a combination^ of hydrastin with xanthoxylin, will admirably fulfill the indication. In chronic rheumatism I have found the following preparation highly beneficial : Take of Cimicifugin, Xanthoxy- lin and Apocynin, of each one drachm, Proof Spirits or Whisky one pint; mix. Of this, the dose is a tablespoonful three times a day, or 974 Materia Medica. sufficient to slightly affect the head, at the same time attending to the surface and excretory functions. Sometimes I add two drachms of guaiacum to the above. The dose of Xanthoxylin is from one to three grains, three or four times a day. ZEA MAYS. Indian Corn. Nat. Ord.—Graminacea?. Sex. Syst.—Moncecia Triandria. THE FRUIT OR SEEDS. Description.—Indian Corn is a monoecious paniceous grass, annual, with a fibrous root, and an erect, leafy stem, channeled on one side, and from five to ten, and in some varieties, from fifteen to twenty feet high. The leaves are lance-linear, entire, keeled, and two or three feet in length; seeds immersed in an oblong receptacle, mostly eight-rowed. History.—This plant is a native of the warm latitudes of America, and its varieties are exceedingly numerous. Corn is universally cultivated in the United States, and also in the southern countries of Europe, and partially in Asia. In America, especially in the warmer portions, it forms the main article of food. It is extremely wholesome and nutri- tious, and is employed in a variety of forms; as it contains no gluten, the meal does not undergo the fermentation called " rising," as with Avheat, rye, etc. The young ears boiled, are in general a nutritious and digestible article of diet, but should be eaten with caution by those pre- disposed to, or suffering from disease of the bowels. According to Dr. Gorham, corn contains 77 per cent, of starch, 3 of a principle analo- gous to gluten, called Zein, 2.5 of albumen, 1.45 of sugar, 0.8 of ex- tractive, 1.75 of gum, 1.5 of sulphate and phosphate of lime, 3 of lig- nin, and 9 of water. A yellow oil has likewise been procured from corn, which has been much used, instead of lard or fish oils, in lamps,—it consists of carbon 79.68, hydrogen 11.53, and oxygen 8.79. Properties and Uses.—The meal is prepared into a gruel, which is sometimes more grateful to the sick than that made from oat-meal ; in the form of mush it is an excellent and nutritious diet for patients during convalescence, and makes an excellent emollient poultice, for ulcers, swellings, rheumatic pains, etc. An infusion of parched corn is useful in allaying the nausea and vomiting attendant upon many diseases; it may be drank freely. ZINCI SULPHAS. Sulphate of Zinc. Preparation.—Take of Zinc, in small pieces, four ounces, Sulphuric Acid six ounces, Distilled Water four pints. To the zinc and water, Zinci Sulphas. 975 previously introduced into a glass vessel, add by degrees the sulphuric acid, and, when the effervescence shall have ceased, filter the solution through paper ; then boil it down till a pellicle begins to form, and set it aside to crystallize. When Zinc is brought into contact with strong sulphuric acid, very little action ensues; but, when the acid is diluted, the water is decom- posed, its hydrogen escaping with effervescence, and its oxygen com- bining with the zinc forming an oxide. This oxide is dissolved by the acid, forming a sulphate of the oxide of zinc, which may be obtained in fine, transparent colorless crystals by evaporation. The object in adding the sulphuric acid gradually, is to avoid the excessive effervescence which takes place when the materials are mixed at once. Impure Sul- phate of Zinc, called White Vitriol, is prepared by roasting the native sulphuret of zinc, or Zinc-blende of mineralogists, in a reverberatory furnace, then exposing it to the air in a moist state until the sulphuret is converted by oxidation of its sulphur and metal into the sulphate ; this is lixiviated, and the solution, concentrated by evaporation, is poured into molds, where it concretes into cakes like loaf-sugar. In this state it contains many impurities, as copper, lead, cadmium, and especially iron, in the form of sulphates ; and from which it may be purified by dis- solving the mass in water, and adding oxide of zinc to it, which precip- itates the metallic bases, and unites with their sulphuric acid, forming sulphate of zinc. The solution may then be filtered, and crystallized by sufficient evaporation. History.—Sulphate of Zinc is a colorless, transparent salt, having an intense, disagreeable, metallic, styptic taste, and crystallizing usually in small four-sided prisms. It effloresces on exposure to the air, is insol- uble in alcohol, but soluble in two parts and a half of temperate water, and in considerably less boiling Avater. When heated, it first fuses in its water of crystallization, which is subsequently driven off; and at a still higher temperature, the anhydrous salt parts with a portion or the whole of its acid, and the oxide of zinc only remains. Its watery solution is precipitated white by the alkalies or their carbonates, oxide or carbonate of zinc being thrown down ; and either precipitate is soluble in an excess of the alkali. Of course, if iron be present, which is generally the case, it is not redissolved. Ferrocyanate of potassium and hydro- sulphate of ammonia also occasion a white precipitate. Crystallized sulphate of zinc is composed of one equivalent of oxide of zinc 40.3, one of acid 40.1, and seven of Avater 63=143.4. Its formula is Zn O-f- S03 -|-7Aq. The commercial White Vitriol contains but three equiva- lents of water. Sulphate of Zinc is incompatible with alkalies and alka- line carbonates, hydro-sulphates, lime-water, and astringent vegetable infusions. Properties and Uses.—By a certain class of practitioners, Sulphate of Zinc is used as a tonic, astringent, and emetic. As a tonic it has been 976 Materia Medica. used in doses of a grain or two, in dyspepsia, obstinate intermittents, epilepsy, chorea, pertussis, debility attended with irritation, etc. As an astringent, its solution has been applied to bleeding surfaces, and chronic inflammation of mucous surfaces. As an emetic, the dose is from ten to thirty grains, and it usually produces vomiting very rapidly. In large doses it is an irritant poison, but seldom produces dangerous effects, as the patient is relieved by the vomiting which it occasions. This agent is never used internally by Eclectics, but is sometimes employed in solu- tion, from one to six grains to an ounce of water, as a collyrium in chronic ophthalmia, as an injection in chronic gonorrhea, gleet, and leu- corrhea, as a gargle in aphthous sore-throat, and relaxation of the uvula; and as a desiccative lotion in old ulcers with excessive discharges. It is also very much used as a local application to cancer, in which disease it has accomplished very beneficial results. Combined with powdered bloodroot, it has been successfully used in nasal polypi, and also in chancres. Prof. R. S. NeAvton has recently discovered it to possess antiseptic properties, and has extensively and successfully employed it in gangrene or mortification ; as this is a matter of some moment to the profession, we extract from his remarks on the subject, as published in the Eclectic Medical Journal, May, 1849, Vol. I, No. 5, as follows : " I am of the opinion, that as far as a constitutional treatment is indi- cated, it will be important to consider the nature of the complaint, and prescribe accordingly ; but in reference to the local application, I think that one single remedy is sufficient to fulfill every indication, and that more dependence may be placed upon it, than upon any constitutional treatment, and there is no doubt but that the profession will willingly hail this discovery. My practice in this malady, has led me to step out of the old beaten track, in search of some agent that can be relied upon for its efficacy, its general application with safety in all cases, with but little modification, and one that will remove the necessity of so much attention to constitutional remedies, in many cases entirely. This agent may also be used in the treatment of some varieties of ery- sipelas, which will be referred to hereafter. Sulphate of zinc is the article to which I wish to draw the attention of practitioners, as a remedy for mortification, and to show its beneficial results, by the description of a feAv cases treated by it. It may be argued, that the use of any remedy that will of itself produce active inflammation, could not be applied to a highly inflamed part, without producing fatal consequences, by increas- ing the disease beyond the reach of remedies. This will doubtless appear true to many, but experience has proved to the contrary, for it has been used in cases where the parts were in the highest state of inflammation, and although this was increased for a few hours by its action, yet in no case have I found it to produce any bad effect, or to so augment this condition, as to present any difficulty in the subsequent treatment. It will be remembered that all cases of mortification are Zinci Sulphas. 977 attended with a very offensive fetor, which is one of the characteristic symptoms of this disease, and which is caused by a decomposition of the healthy structure of the parts attacked, and this very cause produces the continuance of the disease, the changing of which is the indication to be fulfilled in every variety of treatment that has been adopted. No agent will act so immediately in producing this change as the sul- phate of zinc; the most extensively mortified surface, with the offensive fetor arising from it, can be stopped in a few hours after its application, and after one or two applications, the parts become hardened, and the fetor entirely removed. It fulfills two indications in this respect, viz.: arresting the decomposition going on in the parts, and correcting all unpleasant fetor which may exist; and it should be borne in mind, that as long as this fetor is present, the disease is not arrested. The follow- ing cases will be illustrative of the method of using it, in which I have found it useful. Case I.—Mr. F., aged 25, residing in Fulton, came to consult me in December, 1846, with an extensive mortification of the Avhole palatine arch and gums of the superior maxillary, succeeding a mercurial action which had been produced and continued a long time, and which had resisted the usual treatment for its arrest. I was induced to try the sul- phate of zinc, and mixed a small quantity of it in fine powder, with a sufficient quantity of flour and water to make a paste; this, I spread upon soft leather, and applied over the parts affected, retaining it there until the paste sufficiently adhered, by a sponge placed upon the tongue. I would here remark, that this was a well-marked case. The fetor arising from the mouth, was such, that one could scarcely stay in the room with him. On the succeeding day, I found the fetor much dimin- ished, and the parts secreting but little, with a portion entirely hardened. I made a second application, in a similar manner, and on the next morn- ing the unpleasant fetor was entirely removed, and the whole of the diseased parts covered with a dry, hard surface, and no vestige of secre- tion from any part of it. I considered this to have been carried far enough, and made no further application of the zinc, but recommended the mucilage of ulmus and warm water to be used freely in the mouth, which was pursued for three days, when the entire portion upon which the zinc had been used, sloughed off, leaving a healthy appearance of the parts. It may be well to state here, that the entire structure of the arch, with a large portion of the bone, came away, after which it was treated as a common ulcer, and healed in about ten days, since which time he has remained in good health. Case II.—Mrs. S. was under treatment for a cancerous condition of the breast. It had ulcerated, and was attended with all the unpleasant symptoms of such a condition. I made use of caustic applications for its removal, but found upon the second day, that the whole gland was in a state of mortification, and that the system was fast failing from its 62 978 Materia Medica. effect. I immediately applied the zinc, in the form of powder, covering the affected parts with it; in less than six hours a change of the fetid smell Avas very perceptible, but the inflammation continued without any abatement during twenty-four hours. On the next day I found that the remedy had dried and hardened a portion of the diseased surface; I, therefore, again applied it and covered the medicine with a poultice of elm bark, mixed with cold water; this dissolved the zinc in a few hours, and had the desired effect of changing and arresting any further exten- sion of the mortification. In this case two applications were sufficient. It will be found, that in some cases, the zinc will produce a hardened surface, so as to prevent a sufficient quantity from acting throughout the diseased parts; this can be remedied by applying an elm poultice after the zinc is used, which will soften the surface enough to allow its full action, which is known, as before said, by absence of the fetor. All the dressing that is required, is the elm poultice, both before and after the use of the zinc; if the first application increases the inflammation to any extent, apply the elm for ten or fifteen hours, after which apply the zinc. The part will usually slough off in three or four days. Case III.—J. F., aged forty-eight, had an encephaloid tumor, situ- ated on the leg, which required to be removed by an operation, previous to the application of medicine for its permanent cure. J. King, M. D., assisted me in removing the tumor, which had arrived at several inches in diameter. It was removed without any unnatural appearances attend- ing the case. But on the second day, the whole incision, and for three inches around, became gangrenous, and accompanied with a high degree of inflammation. I immediately applied the zinc, and continued it for three days, when it became completely arrested, and in three days longer the diseased parts sloughed off, leaving a healthy condition of the remaining integuments, which were then treated without any further difficulty. I have made use of this agent in forty-five cases, and in each it proved highly successful, so much so, that in only five cases was a slight consti- tutional treatment demanded. As these cases are all similar to those given, I deem it unnecessary to particularize any further. In four cases of ulcerated erysipelatous inflammation, I have used the zinc with simi- lar success, though in these instances, it required a smaller quantity of the article, a greater number of applications, and at greater intervals between the applications. At some future time, I may again refer to this article, and its effects in other forms of disease." Off.

Zingiber Officinale. 979 ZINGIBER OFFICINALE. Ginger. Nat. Ord.—Zingiberaceae. Sex. Syst.—Monandria Monogynia. THE RHIZOMA. Description.—The Ginger plant has a biennial, creeping, tuberous root or rhizoma; the stems are erect, oblique, round, solid, annual, invested by the smooth sheaths of the leaves, and two or three feet in hight. The leaves are subsessile, on long sheaths, alternate, lanceolate, linear, acute, smooth above and nearly so beneath, bifarious, and five or six inches long by an inch broad; the sheaths are smooth, and crowned with a bifid ligula. The scapes are radical, solitary, a little removed from the stems, from six to twelve inches high, enveloped in a few obtuse sheaths, the uppermost of which end in tolerably long leaves, and terminate in oval, obtuse, bracteal, imbricated spikes, about the size of the thumb. The exterior bracts are imbricated, one-flowered, obovate, smooth, mem- branous at the edge, faintly striated length Avise; the interior enveloping the ovary, calyx, and the greater part of the tube of the corolla. Flowers small, of a dingy-yellow color, and appear two or three at a time between the bracteal scales. The calyx is tubular, opening on one side, three-toothed; corolla with a double limb; outer of three, nearly equal, oblong segments; inner a three-lobed lip, of a dark purple color. Sterile stamens subulate ; filament short. Anther oblong, double, crowned with a long, curved, tapering, grooved horn. Ovary oval, three-celled, with many ovules in each; style filiform ; stigma funnel-shaped, ciliate, lodged just under the apex of the horn of the anther. History.—Ginger is supposed to be a native of Hindostan, and is cul- tivated in the East and West Indies, and at Sierra Leone in Africa. The flowers and the stems when bruised, have an aromatic odor, but the root is the officinal part. In a young state these roots are preserved in sugar, forming a well known sweetmeat; when old, they are taken up, scalded in hot water, to prevent germination, and dried, constituting the black ginger of commerce ; or if they are scraped previous to being dried, they form the white ginger. The roots are gathered in January and February, after the stems have withered. The East Indian vari- ety is generally imported from Calcutta, while the West Indian is derived from the West Indies, usually by way of England. The recent root is from one to four inches long, somewhat flattened on its upper and under surface, knotty, obtusely and irregularly branched or lobed, externally of a light ash color, and marked with circular rugae. Inter- nally, fleshy and yellowish-white. The two varieties met with in com- merce, are the Jamaica or White Ginger, and the Common East India or Black Ginger. The latter is most extensively used in this country. In shape it is the same as above described, but has a dark, ash-colored 980 Materia Medica. epidermis, which being removed in some places, exhibits patches of an almost black color, apparently the result of exposure. Beneath the epidermis is a brownish, resinous, almost horny cortical portion. The interior parenchyma is whitish and somewhat farinaceous. The powder is of a light yellowish-brown color. The former differs in being deprived of epidermis, and white or yellowish-white on the outside. The pieces are rounder and thinner, firm and resinous, and possess more of the sen- sible qualities of ginger than the black variety. The powder is of a beautiful yellowish-white color. Ginger is of an aromatic and penetrat- ing odor, with a pungent, hot, spicy and biting taste. It yields its vir- tues to water, proof spirit or rectified spirit. Age or long exposure diminishes its activity. Pieces which are very fibrous, light and friable, or worm eaten, should be rejected. Ginger consists of a greenish-blue volatile oil; a soft, acrid, aromatic resinous matter, soluble in ether or alcohol; a sub-resin insoluble in ether; osmazome ; gum; starch; a vegeto-animal matter; sulphur; acetic acid; acetate of potassa ; and lignin. The flavor of the root probably depends on the volatile oil, and its pungency on the resinous extractive. Properties and Uses.—Ginger is stimulant, rubefacient, errhine, and sialogogue. When chewed it occasions an increased flow of saliva, and when swallowed it acts as a stimulating tonic, stomachic and carminative, increasing the secretion of gastric juice, exalting the excitability of the alimentary muscular system, and dispelling gases accumulated in the stomach and bowels. It is much used to disguise other drugs, conceal- ing their nausea, or preventing their tendency to cause tormina. When snuffed into the nostrils it causes violent sneezing. It has been used in combination with astringents or other agents, in diarrhea and dysentery; prepared with rhubarb, in the form of cordial or syrup, few articles are more valuable in cholera morbus, and cholera infantum. It is eminently adapted to flatulent habits, dyspepsia, hysteria, and the feeble state of the alimentary canal attendant upon atonic gout; and is excellent to relieve nausea, pains and cramps in the stomach and bowels, and to obviate tenesmus. Combined with black willow bark, it forms an excel- lent poultice for indolent ulcers; and is sometimes employed as a local remedy in relaxation of the uvula, and paralysis of the tongue. Dose of the powder, from ten to thirty grains; of the infusion, prepared by adding half an ounce of the powdered or bruised root to a pint of boil- ing water, one or two fluidounces. A large quantity of ginger taken internally might produce serious effects. Off.

COLLECTION AND PRESERVATION OF PLANTS. It is of vital importance to the practitioner that the agents which he employs in practice be as perfect in their character as circumstances will admit; for, no matter how excellent a remedy may be when properly prepared, an inattention to the requisites demanded for their purity and excellence may prove very serious in its results. The custom pursued by some apothecaries of retaining on hand an old and inert stock of medicine, and palming it off upon the physician or his patient as genuine, is very reprehensible, and cannot be too severely discountenanced, and we are glad that this practice is confined to but very few. It is the posi- tive duty of the apothecary to furnish himself with good articles of medi- cine, to take especial care in preserving them, that they do not become soiled or otherwise injured, to prepare them, when called for, in a neat, scientific, and expeditious method, and to dispense them strictly accord- ing to the physician's prescription, without using his own judgment in the matter, or substituting other agents for those which may not be in his store, because, it is not to be expected that he should know the indi- cations which the practitioner desires to fulfill, nor the especial object in view which originated the prescription. One exception, perhaps, may be made, in which the agents are of a deleterious or poisonous character, when, should the apothecary consider, from the largeness of the article, or its dose, if that can be ascertained, that a mistake or oversight may have occurred, it is then his duty, not to alter or modify the prescrip- tion, but to send it back to the physician, or present it himself in person, that it may be examined and corrected. As by far the greater number of agents used in Eclectic practice are derived from the vegetable king- dom, an attention to the following observations will, as a general rule, insure pure and active medicines. (981) 982 Pharmacy. All medicinal plants, with but a few exceptions, have their active quali- ties more or less impaired by long keeping; hence, the pharmaceutist should, as a general rule, reject the supply of the previous year, and provide himself with fresh agents; with our indigenous remedies this is more especially necessary, as these can be, and should be, freshly col- lected every year. Plants should be gathered at a proper period, according to the portion designed for use, and which is generally recog- nized as being at the time when the natural juices of such part exist in it more abundantly. Great attention should be bestowed upon this mat- ter; as the reputation of an agent depends entirely upon its careful col- lection and preservation; thus many of our most active agents possess but little medicinal powers when young, and are at this early period often eaten with impunity as greens, among which may be named the young shoots of poke, asclepias, dandelion, etc. Soil, climate, and cul- tivation exert a remarkable influence on the properties of plants, and, with the exception of the Labiatae, whose aroma becomes much improved by cultivation, nearly all other plants become deteriorated and useless as medicines when reared under the hand of the cultivator. Plants found in their places of natural growth present the greatest degree of medi- cinal activity, consequently, it is recommended to collect these and no others. Most of the Umbelliferae growing in a dry soil are aromatic, while those peculiar to wet places are narcotic and poisonous. The Cruciferae thrive best in damp localities, while the Labiatae found in dry soils are to be preferred. The attention of the herb-collector should always be directed to these several points. Roots.—Roots must be collected according to the character of the plant; thus an annual plant will yield the most actively medical root, just previous to the flowering season; though the generality of this class of roots are erroneously gathered after the flowering period, and conse- quently are less active and do not retain their qualities for any reliable time. The roots of biennial plants are most energetic if collected after the vegetation of the first year has ceased, or on the disappearance of the first year's leaves. The roots of perennial plants are best collected in the winter or early in the spring, previous to vegetation. Bulbs should be collected when the new bulb is perfected, but not yet vege- tated, or about the time the leaves decay. Stems.—Herbaceous stems are best gathered after the appearance of the leaves, but before the time of floAvering. Ligneous or woody stems during the winter, as then the wood contains more extract. Barks.— Barks from the root, body, or stems, should be collected when they can be most easily separated from the wood, and which is generally either previous to the appearance of the flowers, or in the autumn, after the termination of the reproductive process. Too much care cannot be displayed in selecting barks; those which are very young, Collection and Preservation of Plants. 983 or somewhat old, and especially decayed portions, should be at once rejected. Leaves. — Leaves should be collected after their full development, before the fading of the flowers, or previous to the ripening of the fruit or seeds. It must be remembered that the leaves of biennial plants, are not in full perfection until the second year; consequently, they should be gathered only at this period. Flowers. — Flowers must be gathered either before or immediately after they have fully expanded, and some while yet in the bulb. Aro- matic herbs are best when gathered during the season of flowering. Stalks and twigs should be collected in autumn; and seeds as soon as they have fully ripened. Berries and succulent fruits generally, are to be collected only when ripe. Drying of Plants.—This is a very important process in the preserva- tion of medicinal plants, as the activity of an agent depends, probably, as much upon the method adopted in drying it, as upon its inherent qualities. Many remedies are often injured or rendered inert by an improper or careless mode of drying. Leaves, herbs, and flowers, should always be gathered in dry weather; in the morning after the evaporation of the dew is the best period. Much care is necessary, not only in drying roots, but the other parts of plants ; in general, they should be dried in a well ventilated room, and with as much rapidity as may be necessary for their proper preservation; and during damp weather, it will be advantageous to heat the room artificially by means of a small stove, or drum, allowing the temperature to range between 70° and 100° F. The articles to be dried should be so arranged that the currents of air may pass over and through them, and they should be frequently stirred. Roots should be washed, and the fibers, if not used, separated ; then, especially if large and succulent, cut into transverse pieces, from one-fourth to half an inch in length, and dried in the sun, or in the drying room at 100° F. ; in order to prevent molding, they should be frequently turned. Fibrous roots may likewise be dried in the sun, or in a temperature not to exceed 85°. Bulbs may be dried simi- larly, after first having had the outer membranes removed. Barks, stems, woods, and twigs, during the process of drying, may be arranged in thin layers, or hung up in small, loose bundles, and dried in the open air. Leaves are to be dried in a manner which will preserve their natural color; they should be freed from the stalks, and as much as possible from external moisture, then laid in thin layers, and loosely strewed in a dark room, the temperature of which must not be less than 130° or 140° F. and in which they must remain for three or four hours, or until they begin to shrivel. They should then be turned, in the same temperature, which should be maintained for six or eight hours longer; when the operation is finished, which may be known by the leaves readily 984 Pharmacy. crumbling in the hand. Leaves thus dried retain their color and medical properties in a high degree, and should be kept in well-stopped vessels, and carefully excluded from light and moisture. The usual method of drying leaves is to strip them from the stem, lay them loosely on the floor of a dark room, and turn them several times; and when dried, press them in packages. The custom of moistening or steaming leaves and other preparations previous to packing them in bundles, for the pur- pose of causing them to pack more solidly, and which is pursued by many collectors of medicinal plants, is exceedingly improper. The arti- cles become very much deteriorated in quality thereby, and soon mold. Flowers are frequently very difficult to dry, so as to retain both their odor and color. They should be dried rapidly, in the manner recom- mended for the drying of leaves ; and as soon as thoroughly dried should be firmly compressed into packages, and kept in dry situations. Some flowers cannot be completely dried, without destroying their active properties at the same time; these may be kept loosely in proper jars. Berries and succulent fruits may be suspended in bunches and dried, or removed from the branches and spread in thin layers on a wicker frame in a dry and darkened room ; they should be frequently stirred during the drying process. Seeds may be dried, when this is necessary, by spreading them out thinly, and drying in a dark room. Aromatic herbs, and annual plants generally, when not too juicy, may be tied in small bundles, and suspended on lines stretched across the drying-room. In the drying of plants, there is considerable loss of water, and some of the volatile constituents. The Edinburgh Dispensatory gives the fol- lowing table, as showing the amounts obtained from 1000 parts of the respective articles named, after having been dried: Roots of Angelica Arch'l.......... 263 Twigs of Sola.

The store-room should be quite dry, exempt from vermin, and capable of being ventilated when desired. Drugs should not be put away until thoroughly dried, and should be kept from the light, and on the addition of new parcels to the old, the latter should be examined, and freed from all impurities. Roots, barks and woods may be kept in barrels or boxes, with well fitted covers, and other drugs can be well kept in tin canisters, Weights and Measures. 985 or in glass or earthenware vessels. All medicines should be frequently inspected, particularly in warm weather, to prevent injury from insects or dampness, and when the former are discovered, they may be destroyed by suspending an open vial containing chloroform in the canister or vessel holding them, which is to be securely closed, and thus saturate the atmosphere of the vessel with its vapor. Oils, fixed or volatile, are best kept in a dark place, and in a temperature ranging from 60° to 65° F. Care should always be taken to separate the various drugs from admixtures, inert substances and dirt, and the finest quality should always be preserved separate from that of the second. Aromatic leaves, flowers, and pulverized drugs should be kept in tin vessels, or glass jars, and excluded from the light as much as possible, as the action of light upon them impairs their activity. All parts of plants requiring to be kept fresh for as long a time as possible, should be buried in dry sand, especially roots, bulbs, and succulent fruits. WEIGHTS AND MEASURES. In this country the apothecary makes use of the Avoirdupois weight in buying and selling medicines, but employs the Troy measure of weight in compounding and dispensing them, which is divided for the convenience of the apothecary, into grains, scruples, and drachms; thus, twenty grains being equal to one scruple ; three scruples to one drachm ; eight drachms to one ounce; and twelve ounces to one pound ; this measure is frequently termed " apothecaries weight." The fluid meas- ures recognized are the wine gallon and pint. Other measures of an approximative character are also employed in dispensing medicines, as the wineglass, tablespoonful, dessert-spoonful, tea-spoonful, and drops. (See Weights arid Measures in the Appendix.) For the measurement of liquids, graduated glass measures, varying from four to sixteen ounces, are made use of, in which any quantity not less than one fluidrachm may be proportioned; and for obtaining fractions of a fluidrachm, the minimeter, graduated into sixty parts or minims is a ver}*- convenient instrument. The mode pursued by many apothecaries, of dropping liquids from the lip of the bottle, is very inaccurate and objectionable, from the fact, that the drops of various liquids vary considerably in size, and even those of the same liquid vary considerably, according to the size of the vessel from which they are dropped, as the following results of Mr. Alsop's investigations verify. One fluidrachm of Diluted sulphuric acid, yielded " of Scheele's hydrocy. acid, " " of Distilled water, " of Solution of Ammonia, " " of Tincture of Opium, " " of Rectified Spirit, " " of Tine, of Muriate of Iron, " dropped from When dropped from rge Bottle. a Small Bottle. 24 drops, 84 drops. 35 " 70 " 31 " 54 » 40 « 48 " 84 " 135 " 100 " 130 « 100 " 150 ' 9Sfi Pharmacy. From this table will be seen the disadvantages of measuring medicines by drops. To obviate the difficulty heretofore experienced in measuring- fractions of a fluidrachm, Mr. Alsop has invented a minimeter, which is probably the most convenient and accurate instrument for such purposes; it consists of a very slender glass syringe, graduated into sixty parts, each being equal to a minim. DETERMINATION OF SPECIFIC GRAVITIES. It is often a matter of importance to the apothecary to determine the specific gravity of an article, in order to test its purity. The instrument generally used for this purpose, when applied to liquids, is Baume's hydrometer. It consists of a glass bulb, properly loaded at one end, drawn out at the other into a tube, on which the scale is accurately marked. In order that this instrument may be used in small vessels, it should have a very short tube, and especially when intended for syrups, be graduated from 20° to 40° of Baume's scale for heavy liquids. The specific gravities of syrups, acids, and saline solutions are usually ascer- tained by hydrometers. When used for alcohol, the instrument is graduated by loading it until it sinks to the foot of the stem (which is marked zero) in a solution of nine parts of water to one of common salt. It is then placed into water, and the place to which it sinks marked 10° of the scale, which is constructed from these data. For liquids heavier than water, the instrument is loaded until it sinks, when in distilled water, nearly to the top of the stem, which is the zero of the scale. It is then placed in a solution of fifteen parts of salt in eighty-five parts of water, and the place to which it sinks marked 15°, and the scale pro- perly divided off into fifteen equal divisions or degrees, and as many more degrees added as the length of the stem will admit of. Other means are sometimes employed. Thus, a bottle which will hold exactly a thousand grains of water, at 60°, will give the specific gravity of any liquid which it will hold, by the weight in grains of that quantity of the liquid. Such bottles, made very accurately, can be had in the shops. Or an ordinary vial may be employed, and the weight of the liquid examined, being divided by the weight of the water, will give its specific gravity. The centesimal alcoholmeter of Gay Lussac will indicate the per-cent • age of absolute alcohol in any mixture of pure spirit and water. There are several other hydrometers in use, as Fahrenheit's, Nichol- son's, which is also applicable for taking the specific gravities of solid substances, Cartiers', for liquids lighter than water, Twaddle's, Zanetti's, Sike's, and various others. Also hydrometers for determining the den- sity of syrups called Saccharometers; the purity of oil, called Elaeome- ters; the density of urine, called Urinometers, and for ascertaining the quality of milk, called Galactometers. Pulverization of Medicines. 987 To obtain the specific gravity of a solid, it must be first weighed in air and then in water, and the difference between the two divided into the former weight. If the body be lighter than water, after first weigh- ing it in the air, weigh it again in air and water, in connection with a heavier body, which last has been previously weighed in air and in water. The weight of the lighter body in the air should be divided by the excess of the difference between the weights in air and water of the two conjoined, over that of the weights in air and water of the heavier body alone. If the body be soluble in water, its relative weight to that of some other liquid of known specific gravity should be ascertained in the manner above directed, and its weight multiplied by the specific gravity of the liquid. PULVERIZATION OF MEDICINES. In order to reduce medicinal agents to a state of minute division, or to more readily extract their virtues, various processes are employed, as slicing, bruising, rasping, filing, trituration, grinding, sifting, levigation, and elutriation. The most important drugs are, hoAvever, purchased already pulverized, thus saving the apothecary considerable time and labor; yet as much fraud is perpetrated in this department of medicinal preparations, too much care cannot be observed that they are obtained from honest individuals. As it is often necessary, however, to pulverize small quantities of medicines not usually kept in the form of powder, the apothecary should be provided with iron, brass, and Wedgewood mortars, also of glass and marble, several sieves of various degrees of fineness, a hand-mill, cutting-knives, rasp, and a pair of pruning-shears. Pulverization is, under the above-named circumstances, usually per- formed in an iron or brass mortar, with the pestle suspended on a spring so as to assist in elevating it; and to prevent loss, the mortar is covered with a piece of leather, firmly attached to its outer edge, and through the center of which the pestle passes, having the leather fastened to it at that place. The operator should be careful not to introduce too great a quantity of the article at a time, and should also guard himself against the powder or vapor of acrid substances, by covering his mouth and nostrils with a wet cloth, or otherwise. After contusion has been carried on for some time, the finer particles should be separated by the sieve, while the coarser particles are to be returned to the mortar for further bruising, and this course must be pursued alternately from time to time, until complete pulverization is effected. For the coarse division of drugs, the hand-mill may be employed; Swift's drug-mill is probably the best of the kind; and in using it for fibrous roots or barks, as elm bark or sarsaparilla, they should be sliced transversely, in short sections. Trituration is most generally applied to friable and other substances, where it is desirable to bring them to a uniform state of division, and is 988 Pharmacy. accomplished by a circular motion being given to the pestle, accompa- nied with more or less pressure, the circular movement being so made as to bring the pestle alternately in contact with all portions of the sur- face of the mortar. For this purpose, the glass or Wedgewood mortar is usually selected. Levigation is the same as trituration in its principles, the difference consisting in its being effected between the flat surfaces of a slab and muller, which are usually made of glass, porphyry, marble, or Wedge- wood ware; it divides the particles of a substance more uniformly, than the trituration carried on between the curved surfaces of a mortar and pestle. The powder is generally brought into a pasty consistence by means of water, alcohol, or some other fluid in which it is insoluble. Elutriation consists in agitating a powder obtained either by tritura- tion or levigation, in a large quantity of water, allowing the coarser par- ticles to subside, and pouring off the supernatant fluid, holding the finer particles in suspension, that they may settle separately. The pasty thick mass, which is left when the clear liquid is decanted, is then put into a funnel, and dropped in small portions on a chalkstone so as to form small conical masses. In all cases, in order to facilitate the operation of pulverization, all parts of vegetables must be thoroughly dried, especially those contain- ing volatile principles, and resins, gums, and gum-resins must be pow- dered in cold frosty weather; tragacanth and nux vomica must be dried in a stove and powdered while hot. The efflorescent salts may be obtained in fine powder, by exsiccation; and those which are insoluble in alcohol, may be precipitated from their aqueous solutions, in an impal- pable powder, by this liquid. Insoluble substances are best reduced to powder by levigation. Squill and colocynth are best powdered in a dry atmosphere, after being thoroughly dried by a stove-heat. Cloves, cap- sicum pods, cantharides, and the aromatic seeds may be ground in a hand-mill, and afterward triturated. Fibrous roots should always be cut into transverse slices previous to powdering. Magnesia, white lead, and agaric may be reduced to powder by gently rubbing through a fine wire-sieve; or agaric may be beaten into a paste with water, then dried and triturated. Some agents require the aid of an intermedium before they can be reduced to powder; thus, camphor and the hard compound extract of colocynth require the addition of a few drops of alcohol; vanilla, gold-leaf, mace, and oily aromatic substances require the addi- tion of sugar before they can be powdered; phosphorus may be pow- dered by means of lime-water and heat, and the mixture is to be stirred up till it cools. Some articles are prepared for pharmaceutical purposes by filing and rasping, as horn, ivory, nux vomica, iron, etc.; some by turn- ing in a lathe, as quassia, guaiacum-wood, iron-wood, etc.; some by cutting with large shears or a cutting instrument, as herbs, some roots, stalks, etc.; and tin or zinc are granulated by melting them and pouring Separation of Mixed Substances. 989 them into a mortar, heated a little above their melting point, and agitat- ing them rapidly as they cool. In all pharmaceutical preparations, the inert portions of the substances entering into them should be rejected, as the dead epidermis of various barks, inert central woody portions of various roots and stems, etc. SEPARATION OF MIXED SUBSTANCES. Solids are separated from liquids in which they are insoluble, or in which they are not acted upon chemically, by being allowed to subside, and then carefully pouring off or decanting the supernatant liquid,—or a syphon may be used to drain it off, or it may be filtered. Decanting or precipitating jars are larger at the bottom than at the top, and are furn- ished with a lip for pouring; the process of decantation may be facili- tated by holding a glass rod in a slightly inclined vertical position, one end of which is placed in the receiving vessel; the lip of the decanting jar is brought nearly or quite in contact with the upper part of this rod and the liquid poured upon it. The glass rod attracts and gives a direc- tion to the current, and prevents any of the fluid from running down the sides of the vessel. If the circumference of the vessel be so large as to render it impossible to pour with the guiding rod, which is very apt to be the case if its sides be perpendicular, with no lip present, and the fluid contained nearly filling it,—a little grease rubbed over the part of the vessel at which it is designed for the liquid to flow, will by preventing any adhesion of it to the surface of the vessel at that point, cause it to flow in a more cylindrical stream, and with less liability of overrunning the sides of the vessel. Cases, however, occur where, from the character of the fluid, the shape or size of the vessel containing it, or from the disturbance occa- sioned to the precipitate upon motion, decantation is difficult or impos- sible ; in such cases the syphon will effect the separation. The syphon is a bent tube somewhat resembling the letter U, having one leg shorter than the other. By filling it with fluid, and placing the short leg into the fluid to be draAvn off, a current is established toward the longer limb, owing to the greater weight of its contents, and all the fluid may be removed as long as the short limb is kept beloAv its surface. Pipettes are instruments used for removing small quantities of liquids from the surface of precipitates or from places from Avhich it would be difficult otherwise to remove them. A pipette is a slender glass tube with one end drawn to a very small point and capillary orifice, and at an inch or so from Avhich a bulb is blown. The instrument may be straight, or it may be bent above the bulb at an oblique angle. To remove the liquid the small point of the instrument is carefully placed in contact with it, while with the mouth, or which is better, by means of a syringe attached to the upper part of the instrument, suction is made and 990 Pharmacy. continued until the bulb is filled—this is then removed, and the process is to be continued until all the liquid has been removed. When it is desired to separate liquids which are immiscible with each other, as oils and water, ether and water, etc., separating funnels or separators are employed, of which there are three or four varieties. Filtration is the pouring a mixture on a porous surface, called a filter or strainer, through which the fluid only can pass, and which separates the solid from the fluid, presenting the latter in a clear form. Filters are generally made of unsized paper, cotton, linen, woolen cloth, charcoal, glass and sand. Tinctures are usually filtered through paper; syrups through flannel; acids through siliceous sand; oils, syrups, and oxymels through coarse paper, or muslin; melted fats, resins or wax, and plasters through muslin, hair cloth, or wire gauze. Liquids which are affected by exposure to the atmosphere, or which evaporate readily should have the filter in which they are placed covered with a sheet of tin foil or plate of glass luted, with a small hole in the cover, or a small tube may be placed within and against the side of the funnel, extending nearly to the top, so as to form a communication between the atmosphere of the receptacle and that of the funnel. Expression is usually accomplished by screw-presses, for the purpose of separating the last portions of'tinctures, infusions, etc., from the dregs. Fresh plants require to be well beaten, before being pressed, water being added to those which are hard and dry. Succulent fruits may be placed in strong flannel bags, filling about two-thirds, and the juices expressed. Seeds containing oil are to be first bruised, put in strong bags, and then subjected to strong, sudden pressure. Cylinders of strong sheet tin, having the sides pierced with small holes, are usually employed to contain the substance to be pressed ; a block of wood which fits the cylinder, like a piston, being placed upon the substance, and gradually brought to bear upon it, by means of the screw-press. The liquid flows through the small holes, and is received into a tray of tin placed below on the lower platform of the press, and from which it is passed into other vessels. Clarification of liquids may nearly always be accomplished, by beat- ing the white of an egg with water, adding it to the liquid, and then coagulating with a gentle heat. Expressed oils are clarified from muci- lage by boiling them with water. The expressed juices of many plants may be clarified by the vegetable acids. FLUID PREPARATIONS. The active principles of vegetables are obtained by infusion, macera- tion, digestion, decoction, lixiviation, or by displacement. Infusion is the subjecting a substance containing soluble principles, to the action of some menstruum, as alcohol, etc., but most usually water. Fluid Preparations. 991 Hot infusions are made by pouring boiling water on the substance, cover- ing it, and allowing it to remain till cold. Cold infusions are made with cold water, and require more or less time to attain their full strength, according to the ready solubility of the active principle. When liquids are allowed to act upon medicines for some time, at a temperature rang- ing from 60° to 90°, it is termed maceration; if the temperature be higher, but below the boiling point of the liquid, it is termed digestion. Decoction is, when the article has been boiled for a longer or a shorter time, according to the readiness with which its virtues are extracted. The employment of either of these processes depends entirely upon the character of the article to be extracted ; thus, many plants are injured by long boiling, others require it—some yield their properties to cold, others to hot water; and volatile principles are easily dissipated by boiling. Lixiviation is a process used to separate a soluble from a porous insol- uble body ; as for instance, the procuring lye, by lixiviating wood ashes. The method of displacement, or percolation, is an improvement upon this process. It consists in reducing the article to be acted upon to a proper degree of fineness, then soaking it for a few hours with a sufficiency of the spirit to make it into a stiff pulp ; it is then to be packed in a cylinder with the requisite degree of pressure, which can only be learned from experience, and the alcohol or spirit poured over it. The cylinder may be made of tin, twelve inches in length, two and a half inches in diame- ter, or fourteen by four, or seventeen by six ; the lower part of this cylinder is made funnel-fashion, to the base of which a metallic plate pierced Avith holes is accurately fitted, and which, when in operation, should have a thin stratum of carded cotton laid over it, previous to placing in the powder. The solution which first passes through is always in a state of high con- centration, and should be set aside. The others are weaker, and may be evaporated to the proper strength, or mixed with the first portion, as required. The United States Pharmacopoeia gives the following direc- tions for this process : " The kind of filtration commonly designated as the Process of Dis- placement, which is employed in many of the processes of this Pharma- copoeia, is to be effected in the following manner, unless otherwise specially directed: A holloAV cylindrical instrument, called a percolator, is to be used, somewhat conical toward the inferior extremity, having a funnel-shaped termination, so as to admit of being inserted into the mouth of a bottle, and provided internally, near the lower end, with a transverse partition or diaphragm, pierced with numerous minute holes, or, in the absence of such a partition, obstructed with some insoluble inert substance, in such a manner that a liquid poured into it may per- colate slowly. The substance to be acted upon having been reduced to a coarse powder and mixed with enough of the menstruum to moisten 992 Pharmacy. it thoroughly, is, after a maceration of some hours, to be introduced into the instrument, and slightly compressed upon the diaphragm. Any portion of the macerating liquid which may not have been absorbed by the poAvder, is afterward to be poured upon the mass in the instrument, and allowed to percolate. Sufficient of the menstruum is then to be gradually added to drive before it, or displace the liquid contained in the mass ; the portion introduced is in like manner to be displaced by another portion ; and so on till the required quantity of filtered liquor is ob- tained. If the liquor Avhich first passes should be turbid, it is to be again introduced into the instrument. Care must be taken that the powder be not, on the one hand, too coarse or loosely pressed, lest it should allow the liquid to pass too quickly, nor, on the other hand, too fine or compact, lest it should offer an unnecessary resistance. Should the liquor flow too rapidly, it is to be returned to the instrument, which is then to be closed beneath for a time, in order that the finer parts of the powder may subside, and thus cause a sloAver percolation." (For further and more detailed accounts of the various manipulations required in Pharmacy, the reader is referred to " Mohr and Redwood's Practical Pharmacy, by Wm. Procter, Jr., a very valuable work which should be in the possession of every physician and druggist in the country.) DISPENSING OF MEDICINES. The dispensing of medicines from the counter, in which they are extemporaneously combined and prepared in divers modes, constitutes a major portion of the apothecary's duties ; and to perform it correctly, neatly and expeditiously, requires a thorough knowledge of his profes- sion, united with a quick perception, accurate judgment, physical agility, and an expertness at manipulating. In connection with these, cleanli- ness and urbanity are indispensable requisites. The apothecary who attends to the dispensing of medicines should never be found doing so in his shirt-sleeves; there is not a shadow of excuse for it, and no matter how warm the weather may be, a thin light coat should always be worn. Some apothecaries I have seen who lick the mouths of their bottles, after having poured the required quantities of fluid from them, or who, in helping themselves to syrups or other preparations kept in bottles, apply the mouth of the bottle to their own mouth, instead of pouring it into some proper vessel from which they could drink it; these are very disgusting habits, of which no properly bred person would be guilty, and which alone should be sufficient cause for a withdrawal of all public patronage. And if these are valid reasons for bestowing custom upon some more cleanly dispenser of medicines, what can be said of those individuals who scratch their heads, and blow their noses with their fingers, not only while in the act of preparing medicines, but even Dispensing of Medicines. 993 in sight of their patrons ? A man of coarse mind, possessing none of the polish of refinement, and having no regard or care for the views or sentiments of others relative to the above points, is no more fit to dispense medicines than the most ignorant boor. Medicines are, in general, suf- ficiently repulsive, without having extra-aversion added to them through disgusting and uncleanly habits, and the apothecary should so observe and regulate his actions as to win the confidence of the most fastidious individuals. A neat, cleanly and orderly store, a polite, attentive, and cleanly apothecary or clerk, devoid of all offensive habits whatever, together Avith accuracy, neatness and dispatch in filling prescriptions, will always command the confidence and patronage of physicians, as well as patients. In Eclectic practice, decoctions and infusions are seldom ordered in prescriptions; but where they do occur, the infusion mug of Mr. Alsop of London, will be found one of the best instruments for facilitating the process. If an infusion or decoction be strained while hot, and bottles heated previously in order to prevent their cracking, be filled with it, it may be kept for some months, even in hot Aveather, provided the bottles be so stopped with accurately ground stoppers, as to have the stopper displace its own bulk of the liquid. The hotter the liquid, and the freer from air-bubbles, the longer will the infusion be preserved. Cork stoppers may answer the same purpose, provided the orifice in the neck of the bottle be instantly closed, and the cork covered with sealing wax. Aromatic waters may be made extemporaneously, by rubbing together two drops of any essential oil with five or six grains of carbonate of magnesia for every fluidounce of water, adding the water gradually while rubbing, and then filtering. Water may likewise be saturated with camphor, by triturating the gum Avith carbonate of magnesia first, and then gradually adding the water. The oils, solid fats, and gum- resins triturated with camphor, render it miscible Avith water; one-fifth of gum-myrrh will render a large proportion of the camphor miscible wish Avater. Camphor softens the gum-resins. In the prepara'ion of emulsions, the gum-resins should be triturated until all the particles are sofcened, and then strained. Ether becomes more soluble in water by trituration with spermaceti, separating the excess of spermaceti by filtra- tion. Elaterium may be thoroughly incorporated with other articles, by rubbing it at first with a little alcohol, and then with sugar or syrup. A little olive oil added to a few drops of croton oil, ordered in a mixture, will render the mixture more permanent. All vessels used by the apothecary should be cleansed immediately after using them, wiping them perfectly dry. Fatty substances and resins may be removed by pearlashes or other alkali, or alcohol; prus- siate of iron by pearlash ; metallic substances by nitric or muriatic acids; the odor of essential oils, musk, etc., may be removed by bruised peach- kernels, or peach-leaves, or other articles containing hydrocyanic acid— 63 994 Pharmacy. in all cases having first removed fats, if present, by some alkaline solu- tion, and resins by alcohol. The dispensing scales should be kept constantly clean, and in some place not exposed to the dust, as for instance, in a glass case, and they should be frequently examined to ascertain whether they continue properly adjusted. Scales adjusted to weighing grains and parts of an ounce, are easily rendered inaccurate by being placed in situations where they are exposed to much jarring, or frequent unnecessary handling; the apothecary Avill do well to observe this statement, and act in accordance with it. In some parts of this country, it is not uncommon for the dispensing office to contain one or more idlers or loungers, during a portion of every day, who, from their continual staring at lady-customers, as well as their tobacco-spitting and smoking, drive the respectable portion of patrons to other shops ; these are more generally the associates of the assistants or clerks, who, without intending offense frequently offend very seri- ously. A proper course should be adoped in relation to this class of visitors. COMPOSITION OF VEGETABLES, AND THEIR PROXIMATE PRINCIPLES AND PROGRESS IN PHARMACY. BY W. S. MERRELL, A. M. The Vegetable Kingdom is the great source from which all animal life derives its nutriment in health, and for the most part its medicine in disease. All vegetable matter is composed of a very few elementary substances—carbon, hydrogen, oxygen, and nitrogen, constitute nineteen- twentieths of all the innumerable variety of the vegetable world. The small quantity of silex, potassa, soda, lime, iron, etc., which compose the ashes after combustion, constitute the rest. But these feAV primary principles enter into a great variety of definite combinations, which form distinct organized substances, which we term proximate principles. These, although composed of the same primary elements, yet, in conse- quence of the different proportions of them, and the different arrange- ments of their particles, possess properties altogether peculiar and different from each other. Of these proximate principles of vegetable matter, the most abundant is the Lignin, or Woody Fiber, which constitutes the frameAvork, and, as it were, the bones of all vegetation. It is insoluble in all ordinary menstrua, and is that portion of a plant which is left after having been fully digested in water, alcohol, ether, or dilute acids. It is, therefore, considered inert, and as possessing neither nutritive, nor medicinal properties. Next in abundance, and first in importance in the constituents of plants, are those proximate principles which are capable of being digested or changed by the action of the gastric fluids, and Avhich are thereby assimilated to the principles of the animal organism, and thus nourish Composition of Vegetables. 995 and sustain animal life. Such are starch, gum, mucilage, sugar, fixed oil, vegetable albumen, gluten, and a few others analogous to these. AH vegetables in which these constitute a large proportion unmixed with other constituents that are deleterious, are useful for the food of man and animals. But, beside these, there are a great number of other organized com- pounds or proximate principles found in the vegetable kingdom, which are incapable of being so assimilated, and, therefore, afford no nourishment to the animal tissues, but which, nevertheless, when taken into the system, or applied upon its surface, change, or in some way affect the action of the animal functions. Many of these, if taken in considerable quanti- ties, derange, and even destroy the healthy action of those functions, and are thus regarded as poisons ; yet, when those functions are deranged by disease, they serve, Avhen administered in appropriate doses, to arrest such morbid action, and to restore such functions to their normal con- dition, and thus they become important medicines. It is the study of the nature of these substances, and their proper application to the preservation or restoration of health, that constitutes the high calling of the physician ; and the proper mode of preparing and dispensing them, constitutes the scarcely less important avocation of the pharmaceutist and the apothe- cary. In their earlier application to the healing art, those vegetables which contained medicinal properties were either administered in substance, in the form of powder, in which case all the woody fiber and other inert elements were thrown together into the stomach, often in large and repulsive doses, or else their more soluble principles were extracted by infusion or decoction, and given in copious and nauseating draughts. The first of these forms is now seldom eligible, except for administer- ing those vegetable products which nature herself has presented in a high degree of concentration, or of those whose medicinal principles are so very active, that the bulk thus required is not objectionable ; and the latter may now be dispensed with, except in cases where it is desirable to present the medicine to the stomach very much diluted, or where the indications to be fulfilled make it expedient to accompany it Avith large draughts of hot or tepid fluids. It was one step in progress, from these forms, to dissolve out the medicinal principles of plants or roots by Wine or Spirits, and present them in the form of medicinal tinctures. This was, in many cases, an improvement on the watery infusion or decoction, because such tincture could be preserved for some time unchanged, and thus be kept ready prepared for immediate use, but chiefly, because alcohol is an almost uni- versal solvent of the medicinal proximate principles, many of which are scarcely soluble in aqueous fluids, and are, therefore, not extracted by such menstruums. But in many cases, even this form of dispensing medicine is very objectionable, on account of the large proportion of alcoholic 906 Pharmacy. stimulus with which the medicinal principles are thus combined, and which renders them almost inadmissible in diseases of an inflammatory type. Of such a character are many of the numerous officinal tinctures still found in the pharmacopoeia of the so-called regular practice. A feAv preparations of this kind may be still properly retained in the Eclec- tic Materia Medica, but it should be only those of the more powerful medicines of which the dose is sufficiently small, and these should be, mostly, saturated tinctures, containing as much of the medicinal principle of the substance as the menstruum will hold in solution. (See Art. Tinctures.) Another improvement on the crude administration of vegetable medi- cines, was the formation of Aqueous Extracts, by dissolving out all the constituents of a plant that are soluble in boiling water, and then evapo- rating off the liquid until the exhausted matter was of a suitable con- sistence to be formed into pills. By this means, the bulky and inert lignin is dispensed with, and the medicinal agents presented in a form and bulk somewhat less objectionable. This is still an eligible form of presenting many valuable medicines. (See Art. Extracts.) But in most cases, it is liable to several objections, as, Avhen the active principle is of a resinous or oleaginous character, it is very imperfectly soluble in water, and, therefore, the aqueous extracts of vegetables containing such prin- ciples are comparatively worthless, from the fact that the real active agent is still left behind in the refuse; again, if the medicinal principle is volatile, as it is in many instances, then it is dissipated and lost in the process. In other cases the active principle is of so delicate a nature as to be chemically decomposed and destroyed by the continuous action of the hot water necessary to the process. This is the case with the arum, sarsaparilla, stillingia, and many other most valuable remedies. More- over, in this process, the starch, gum, mucilage, coloring matter, and all the other non-medicinal principles are extracted, as well as the medi- cinal, and as we do not know what proportion the latter bear to the former, in different specimens of the plant, the extract may appear well, and yet be almost inert. The next great step, therefore, in the progress of pharmacy was to unite the principles of these two improvements, and form the Alcoholic Extracts. Alcohol, as before observed, is an almost universal solvent of those proximate principles of vegetables on which their medical vir- tues depend. I know of no principle of such activity as to deserve the name of medica], which, in its native combination, is not dissolved by this agent, either pure, or Avhen diluted to the strength of proof spirit. The alkaloids, resins, essential and fixed oils, acids, salts, and neutral principles, all, as they are found in their native combinations, are soluble in these menstrua; while on the other hand, the non-medicinal principles, as starch and gum, which, next to the lignin, are the most abundant elements in most vegetables, are quite insoluble in pure Composition of Vegetables. 997 alcohol, and but partially soluble in dilute. By obtaining, therefore, an alcoholic or hydro-alcoholic tincture, either by digestion or displacement, and then distilling off the alcohol and carefully reducing the residue to a pilular consistence, an extract is obtained which, in the first place, fully contains all the medicinal principles of the substance in their native proportions, and, in the second place, is diluted by but a small propor- tion of those non-medicinal substances which abound in the watery pre- parations. These extracts, moreover, will generally keep unchanged, while those obtained by water, and especially the inspissated juices, which are the best preparations of that class, are liable to mold, or become otherwise decomposed. Another important form of the alcoholic extract, and one that is justly becoming very popular, is that in Avhich the concentration of the tincture is not carried to the pilular consistence, but is left in a fluid or semifluid state, and preserved from decomposition by the little alcohol in it, or by the addition of a sufficient quantity of sugar or other antiseptic. These are called Fluid Extracts, and will be referred to again, when the cases in which they should be preferred, and their peculiar advantages will be noticed. (See Fluid Extracts.) Almost every article of the vegetable Materia Medica, might properly be prepared and presented in the form of alcoholic, or hydro-alcoholic extracts, either inspissated or fluid; for even where the active principle of a plant has been fully isolated, these preparations will often be found convenient. Still they are not perfect pharmaceutical preparations, for even alcohol dissolves the sugar, coloring matter, and other inert principles of vegetables with which the real medicine is combined, and as these are not uniform in their proportions, but vary according to the season of gathering, and other circumstances, such extracts are not, therefore, definite and uniform in their strength, even when made with the greatest care. And a source of still greater disappointment, is their ever varying quality, according to the skill and honesty of those who prepare them, and their strength is subject to no convenient test but that of actual demonstration. Therefore, when employed, those only should be relied on, which are made by pharmaceutists of acknowledged skill and integrity. But another step has been taken: these objections are obviated, and pharmacy placed among the exact sciences of the age. This consists in separating that proximate principle,—that peculiar organized substance on which the medicinal virtues of a plant depends,—from all the other substances with which it is combined, and thus presenting the very medicine itself, in a pure isolate state. One great advantage of this improvement, is the smallness of the bulk to which medicines are thus reduced. Of these preparations, the physican can carry in his pocket an assortment, which once required a horse-load, and can administer in a single pill or delicate powder, a dose 998 Pharmacy. at which, in its cruder forms, the stomach revolted. But it has another and even more important advantage than this, and that is the definite- ness with which medicines so prepared can be apportioned. In every other form in which vegetable medicines can be presented, their strength, as has been observed, is constantly subject to variation, and the physician is not only often in doubt what doses to prescribe, but is frequently at a loss whether to attribute his failure in obtaining the desired result, to the inertness of the medicine, or to his misjudg- ment in selecting the proper agent. Thus, for example, two samples of Peruvian Bark, or the ordinary tinctures or extracts obtained, may appear equally fair, and both be unadulterated, and yet one contain ten times the medicinal virtue of the other. But with regard to the proxi- mate principles, this does not occur; the physician who prescribes one grain of quinia, knows just how much of the real medicinal substance he is administering, and it matters not whether it required twenty or two hundred grains of the bark to yield that amount,—itself, is definite and invariably of the same strength. In relation to these principles, the only question is, are they pure? And being definite chemical substances, their purity may in most cases be easily tested. These proximate principles are divided into several general classes, distinguished by their general characteristics and reactions with other substances. These are the Acids, Fixed Oils, Essential Oils, Resins, Resinoids, and the Alkaloids, and perhaps a few others that cannot properly be classed with either of these. Every medical plant, as has been before intimated, contains one or more of these principles, on which all its virtues as a medicine depends; and all the skill of the enlightened pharmaceutist is now called into requisition to separate these from their native combinations, and present them in their purest and most eligible forms. Acids are, in general, readily recognized as those substances which give a sensation of sourness to the taste; but the term is chemically applied to all substances which redden vegetable blues, are electro-nega- tive in relation to other principles, and combine with alkalies to form neutral compounds. The acidity of certain fruits, and other parts of vegetables must ever have been noticed, but it is of comparatively modern date that the different vegetable acids were distinguished from each other. We now recoeuize the Malic, Citric, Tartaric and Oxalic acids, as existing abundantly in fruits, etc., either pure, or combined with po- tassa in form of bi-salts, or those in which the acid predominates. In general, they are isolated from their native combinations by saturating them with an alkali or metallic oxide, and in this state, separating them by precipitation or crystallization, and then decomposing such neutral com- pound, and removing the alkaline or earthy base, by the superior affinity of some stronger acid, generally the sulphuric. After which, except- ing the malic, they may be further purified by repeated crystallization. Composition of Vegetables 999 These acids are used, in their uncombined state, to form coolino- and febrifuge draughts, also as antiscorbutics, and in combination they form valuable hydragogue aperients. Beside these four vegetable acids, Avhich are so manifestly distinguished by their sourness, there are several other electro-negative principles found in certain vegetables, as the benzoic, tannic, gallic, and other acids, all possessed of peculiar and valuable medical qualities ; and by natural decay and destructive decomposition, an almost indefinite number of similar organic substances are found, capable of uniting with alkaline bases, and forming an endless variety of neutral compounds. But few of these have yet been examined, with reference to their medicinal action, and, therefore, Avith the exception of the well-knoAvn article, vinegar, which is formed by the combination of oxygen Avith liquids that have undergone the vinous fermentation, they form no part of the Materia Medica. The Fixed Oils too were obtained and used in medicine at an early period. They are analogous to the acids in being electro-negative, and as such, they combine with alkalies, and form compounds called Soaps. They are obtained in abundance from many seeds and fruits by simple grinding and expression; but most of them, as of the olive and linseed, possess feeble medicinal powers, and are useful for food and in the arts, rather than as sanative agents. Indeed, it is probable that the medici- nal virtues of most of the expressed oils depend, not on the oil itself, but on other peculiar principles held in solution by it, the same as the peculiar flavor and medical qualities of different kinds of spirits, as rum, brandy, gin, etc., depend not on any singularity of the alcohol itself, but on certain volatile oils dissolved in it. In some cases at least, as in that of mustard, the fixed oil may be obtained, by expression, bland and almost tasteless, while the more active principle is left behind, and may be afterward obtained by other means. A few of the expressed oils, however, as those of ricinus and croton tiglium, are powerful and valu- able articles of the Materia Medica. The Essential Oils constitute another important class of proximate medical principles. These differ from the fixed or expressed oils in being volatile without decomposition, and in being, for the most part, warm and pungent to the taste, and powerfully stimulant in their medici- nal character. As the process of separating them from other substances is simple, many of them were long since discovered and prepared. They are mostly procured by the simple process of distillation; the plant, or the part of it containing the oil—usually in its recent state—is put into a large still, with a portion of water, and by converting the latter into steam, the volatile oil of the plant is carried over in vapor with it, and is condensed by passing through a suitable worm or condenser of other form. The oil separates from the water, for which it has no chemical affinity, and either floats or sinks, according as its specific gravity is greater or less than the water, and is thus easily separated. 1000 Pharmacy. In this manner are obtained the oils of mint, sassafras, cloves, etc., and with a few exceptions, all others of a valuable character. Gum camphor, so called, belongs to this class of medicines, being only an essential oil in a concrete or congealed state, at ordinary temperature; and several others, as those of the anise and the rose, assume this con- crete form Avhen the temperature is only moderately reduced. Several medicines of this class are used, and highly esteemed, in the Eclectic practice, which are yet wholly unknown to the old pharmacopoeias, among which are the oils of Erigeron Canadense and Erechthites Hieracifolius. From these oils we pass, by an easy transition, to another class of the proximate principles, viz.: the Resins, many of which appear to be formed from the volatile oils by the absorption of oxygen, which renders them fixed and concrete. Thus, the purest Camphene, or oil of turpen- tine, by exposure to the air, combines with its oxygen, and is gradu- ally changed into a diminished quantity of common rosin; and almost all essential oils become thickened and resinous by long standing, unless entirely excluded from the air. The pure resins, and many gums with which they are compounded, were early found and recognized as dried exudations from certain trees. Their distinguishing characteristics are ; their fusibility by heat, great inflammability, insolubility in water, solubility in alcohol or essential oils, and their capability of combining with alkalies, forming saponaceous compounds. The resins (or so called gums) of the various species of pine, spruce, and larch are of this character. The Gums, properly so called, are distinguished by the opposite char- acteristics, not being fusible by heat, not readily inflammable, not soluble in pure alcohol, but soluble in Avater forming a viscid fluid, called muci- lage ; such are the gums of acacia, prunus, amygdalus persica, etc. These are articles of diet rather than medicine, and are used in pharmacy only as demulcents and vehicles to shield the action of more active agents. There are, however, an intermediate class of articles called Gum- resins, partaking in part, of the properties of each of the above, and which are active and important articles of the Materia Medica; such are the gum myrrh, assafetida, ammoniac, and gamboge; but of these, the resinous portion is the medicinal one, for alcohol, which dissolves the resin and leaves the true gum, holds in solution all their medical virtues. But there is another class of resinous substances, less abundant than those, which exude from the trees that contain them, and which possess medical virtues of a much higher degree. They exist in roots, and, in some cases, other parts of numerous plants, but combined with such large proportions of woody fiber and other principles, that they can be separated only by chemical agency. These possess, in general, the properties of the common resins, viz; fusibility, inflammability, solubility Composition of Vegetables. • 1001 in alcohol, and not in water, etc., but as they are not fully liquifiable by heat, and differ somewhat in other respects from the pure resins, Ave term them Resinoids. Many of them may be obtained by the following simple process; form a saturated tincture of the root or plant desired, which is best done by displacement, or leaching alcohol through the ground material. From this tincture, distil or evaporate off the alcohol, having previously added plenty of water; the alcohol, which held the resin in solution, being thus removed, and the resin not being soluble in water, it is precipitated, while the other substances which the alcohol had dissolved out, as the extractive and coloring matter, being also soluble in water, are held in solution by the water and thus separated from the resinoid. The pre- cipitate is then collected and purified by frequent Avashing, or by being redissolved in alcohol, and again precipitated—and is then dried and powdered for use. Thus may be obtained the resins of podophyllum, cimicifuga, leptandra, etc. By this process alone, the resinoid is not obtained in its chemically pure state: it probably still contains from two to five per cent, of color- ing and extractive matter, which, however, does not sensibly affect its use as a medicine. While a further purification would not only add to its cost, but might even endanger its activity. Its complete purification must be effected by redissolving it in alcohol, digesting the solution with animal charcoal, then filter, and again precipitate by water. In some analyses, the resin has been separated by boiling the sub- stance in milk of lime, or some other alkali, by which the resin is sepa- rated and rendered soluble, and from which solution it is precipitated by neutralizing the alkali with an acid. By this means the resinoid is obtained very cheaply, and very fair in appearance, but its medical pro- perty is nearly or quite destroyed. It is, indeed, no longer the resinoid, but probably bears the same relation to it that stearic acid, which has passed through the same process, does to stearin, and the precipitate thus obtained from podophyllum is not podophyllin, but podophyl-/wM*c acid. The process is an eligible one for scientific analysis, for as the stearic acid obtained is a correct indication of the amount of stearin con- tained in a given quantity of fat, so would this acidified resin be of the true resin or resinoid in a given quantity of the root. This was the process pursued by Mr. Wm. Hodgson of Philadelphia, in his analysis of podophyllum, as published in the United States' Dispensatory; but the process is entirely inapplicable in pharmacy, as the product is worth- less. Mr. Hodgson did not obtain podophyllin, but podophyllinic acid; and yet Dr. J. Kost, who now professes to have made and recommended many of the resinoids before they were introduced at the Eclectic Insti- tute in the summer of 1848, not only does not mention them in his " Family Physician," published one year previous, but in his Materia Medica, published in 1849, gives the above futile process for preparing 1002 Pharmacy. them, plainly showing that up to that period, he had never made a genuine article. The introduction of these and analogous preparations into the Materia Medica, Avhich is of very recent date, constitutes an era in medical prac- tice, especially in that of the Eclectic schools of medicine. The distin- guished and lamented Prof. T. V. Morrow, pronounced the discovery of the podophyllin alone, the greatest improvement in pharmacy that had been made for the last thirty years. Until within the present century, the science of vegetable analysis Avas unknown; and within the last few years, the researches of chemists in this field had shown that many vegetables contained, among other proxi- mate principles, those of a resinous or resinoid character; but, for the most part, such discoveries lay as dead and useless facts in the records of science, without being applied to any practicable use. Nor was it even ascertained, in most cases, that such resins contained any medical power, much less that they Were the depositories of the principal, if not the whole medical virtues of the plants that contained them. To this there Avere a few exceptions; the resin of jalap Avas known to the pro- fession, and used as an active medicine. Professor Tully, of NeAv Haven, Connecticut, had obtained the resin of cimicifuga, and perhaps of some others, and recommended them to the attention of his medical brethren;* but it is not known that any other one eArer prepared or used it. Profes- sor John King, the author of the present volume, first discovered and sepa- rated the resins of the podophyllum, cimicifuga, iris, and several other roots, and used them successfully in his own practice for a series of years; and as early as July, 1844, in the "New York Medical Philo- sophical Journal," and again in April, 1846, in the "Western Medical Reformer," he introduced and recommended them to the Eclectic Medi- cal profession, as valuable agents in several forms of disease; but these discoveries and recommendations had passed unheeded, and were unapplied, chiefly, it is presumed, because other practitioners could not devote the time and skill necessary to their preparation, and because no pharmaceutist had undertaken their manufacture. But in the summer of 1848, the Avriter of this article separated them, with several others of his own discovering, and having the advantage of being engaged in the sale instead of the administration of medicines, immediately put them up in a neat and eligible form, and thus directly presented them to the notice of the profession. Since that time their sale and use have increased with an unexampled rapidity, which shoAvs how high an estimate is placed on them. To the Eclectic branch of the profession belongs the honor of first discovering, testing and adopting them. Physicians of the Physo-medical school * I am not aware that Prof. Tully ever obtained this resin, though he mentioned its existence to me.—J. K. Composition of Vegetables. 1003 soon followed in the use of them, and their pharmaceutists in their pre- paration and sale. And at the present time, hundreds of physicians of the old Allopathic schools are testing and adopting them. The names applied to these resinoids, by the writer of this, on pre- sentino- them to the profession, have now become generally adopted, and which are formed by changing the termination of the generic name of the plant into in, after the analogy of Resm, or Rosm/ thus from Podo- phyllum, we have Podophyllin ; from Leptandra, Leptandrin, etc. The most important of these Resinoids, when properly prepared, are dry and pulverizable, and are prepared for the profession in that form ; but a larger proportion of this class of principles possess so much of an oleaginous character, or the resin is so combined Avith a fixed oil, that they cannot be reduced to the powdered state without injuring, if not destroying them. These we denominate Oleo-resins, and they are of all degrees of consistence, from the almost perfect fluid of the Ptelein, to the buttery spissitude of the Xanthoxylin,. and the tough, gummy compactness of the Cypripedin and Asclepidin. But they all belong to the same general class of proximate principles, and are obtained pre- cisely in the same manner as the dry resinoids, above described. And they are less popular and less used than the powdered resinoids, because they cannot be so conveniently combined with other medicine, and are not so easily administered as the dry. But they possess all the advan- tages of great concentration of medical power, and of perfect definite- ness of strength, which is the distinguishing character of the pure prox- imate principles. There is one class more of these medical principles, which deserves our special notice, and which, together with the resinoids just noticed, forms the acme of improvement in scientific pharmacy. This is the Alkaloids. The Resinoids are electro-negative substances; the Alkaloids, electro- positive ; those combine with alkalies and form saponaceous compounds,— these combine with acids and form salts ;—those are mostly colored and opake—these mostly white and crystalline. The great pioneers in this branch of Pharmacy were Pelletier and Caventou of France, who per- fected the discovery of Morphia, Cinchonia, and Quinia, and who were the first to clearly define the chemical character of these agents, in about 1820. I say, perfected the discovery, for like every great improve- ment in art or science, there were previous discoveries approximating to the result. The Alkaloids do not generally exist in vegetables in their pure state, but in the form of salts produced by their combination with some pecu- liar acid. Thus, morphia is found in opium combined with meconic acid, forming meconate of morphia, and quinia exists in the barks combined with kinic acid, forming a kinate of quinia. These native salts are in a greater or less degree soluble in water; but the pure alkaloids are very 1004 Pharmacy. sparingly soluble in that menstruum, although soluble in hot, and most of them, in cold alcohol. But as the processes of separating and puri- fying them are various and complicated, and are abundantly described in different works on the subject, the student is referred to them for that instruction. By these and similar processes, those substances Avhich were once considered as homogeneous, have been analyzed, and made to yield those principles on which their virtues depend, pure and iso- lated. And those agents which are provided for the healing of our infir- mities, are presented in doses, small, definite, and less repulsive. But while we refer with pride to the work which has already been accomplished, we must not forget that the field has, as yet, been just entered. A vast expanse is yet to be explored. Not one-tenth of the articles of the Materia Medica have yet been analyzed, and in most of these even, the examination has been partial and imperfect. The physi- cian, however, should not rest satisfied, nor the pharmaceutist stay his hand, until, as in the mineral, so in the vegetable kingdom, every known substance should be made to yield both its elementary and its proximate principles, separate and isolated ; and the action of the latter on the animal economy, should be tested and made known. ACETA. Vinegars. These are officinal liquid medicines, formed of vinegar, and charged by maceration with different medicinal principles. Many medicines con- tain active principles which are not readily soluble in water or alcohol, or are, perhaps, insoluble in them, but which are freely soluble in vine- gar ; others again, although soluble in water or alcohol, are not as effi- cient and energetic thus prepared, as when tinctured in vinegar ; on this account, medicated vinegars are especially useful in many instances. The vinegar of commerce is very apt to contain impurities and principles which lead to its decomposition, hence, when used as a solvent for phar- maceutical purposes, it should always be purified by distillation. The solvent property of vinegar depends chiefly upon the acetic acid which it contains, and which renders it an excellent menstruum of the organic alkalies, which it converts into acetates, thereby in many instances pro- ducing more efficient preparations from them. Alcohol is usually added to medicated vinegars, on account of their proneness to spoil, and owing to which, it is preferable to prepare them only in small quantities that they may not be kept for any considerable length of time. Mr. W. S. Merrell states " that in the vinegars of lobelia, and sanguinaria (or where the color of the preparation is necessarily dark), good cider or wine vinegar is to be preferred to distilled vinegar; and in these prepa- rations the alcohol necessary for their preservation should he first added ACETA. 1005 to the powdered ingredients so as to aid in dissolving their oily and res- inous principles, and then displaced or expressed Avith the vinegar. When a pure vinegar is desirable, the acetic acid of the shops diluted with six parts of pure water, forms a more definite, and therefore, more eligible preparation than the Acetum Destillatum." Acetum Destillatum. Distilled Vinegar. Preparation.—Take of Vinegar a gallon. Distil, by means of a sand- bath, from a glass retort into a glass receiver, until seven pints have been distilled, when discontinue the process. Keep the seven pints for use.— U. S. History.—In this distillation, the first portion Avhich passes into the receiver, contains alcohol and pyro-acetic spirit, these being the most vol- atile ingredients ; secondly, the acetic acid passes over in a purified condition, but being less volatile than water, it is weaker than it existed in the vinegar. A good substitute for distilled vinegar may be made by adding one part of strong acetic acid to five or six parts of distilled water, or sufficient to give the density of distilled vinegar, Avhich is 1.005 to 1.006. A fluidounce of distilled vinegar should be saturated by thirty-five grains of crystallized bicarbonate of potassa, which is a proper test of its strength. Wine vinegar is usually preferred to cider or malt vinegar, as it furn- ishes a stronger and more aromatic distilled article ; and when distilled it should be in glass vessels, as the use of lead or copper vessels or tubes is extremely hazardous, from the danger of metallic impregnation. The surest test of the purity of distilled vinegar, is its saturating poAver, as above-mentioned ; its specific gravity cannot be depended upon, as it will vary according to the amount of alcohol or pyro-acetic spirit which may be present. Distilled vinegar is a clear, colorless liquid, having a faint but percep- tible acetous odor and taste, less agreeable, however, than those of com- mon vinegar. It is wholly evaporated by heat. It usually contains a small portion of organic matter which passes over in the distillation, which is liable to partial decomposition, and Avhich, when thus decom- posed, causes the reddish or brownish color upon saturation with an alkali. Pure distilled vinegar is devoid of any empyreumatic taste, or sulphurous odor ; but that generally met with is slightly empyreumatic. It may be rendered unfit for pharmaceutical purposes by the presence of metals or mineral acids. If copper be present, saturate the vinegar with ammonia, and add ferrocyanuret of potassium, Avhich occasions a brown cloud. If lead be present, the addition of iodide of potassium causes a yelloAv precipitate. If it be tainted with tin, the addition of a solution of chloride of gold will occasion a purplish color. Sulphureted- hydrogen occasions a dark-colored precipitate, when either of the two last metals are present and its non-action proves the absence of metals generally. Sulphuric acid may be detected by acetate of lead, or 1006 Pharmacy. chloride of barium ; muriatic acid by forming a precipitate with nitrate of silver ; and nitric acid by the solution of silver digested in the vine- gar, which metal may subsequently be detected by muriatic acid. Properties and Uses.—The properties of distilled vinegar are similar to those of ordinary vinegar, (see page 151). Acetum Lobeliae. Vinegar of Lobelia. Preparation.—Take of Lobelia Seed, in powder, four ounces ; Dis- tilled Vinegar two pints. Macerate the Lobelia Seed with the Distilled Vinegar, in a close glass vessel, for seven days ; then express the liquor, filter, and add to the filtered product, Alcohol one fluidounce. History.—In this preparation, Diluted Acetic Acid may be used as a substitute for the Distilled Vinegar. The Alcohol is added to retard the decomposition, and as its quantity is very small, no objection can reason- ably be made to its presence. We have known this preparation to retain its activity for two years, when kept well corked and not exposed to the action of light. Properties and Uses.—Vinegar of Lobelia is an emetic, nauseant, and expectorant, and is a valuable relaxant in spasmodic affections. It may be given to fulfill all the indications for which lobelia is administered. Externally, it forms an excellent application in several cutaneous dis- eases, as salt-rheum, erysipelas, poisoning by rhus, etc. Dose, as an emetic, from one to four fluidrachms, repeated every fifteen minutes; as an expectorant, from five to thirty drops or more, every half hour or hour, in elm or flaxseed infusion. Acetum Sanguinariae. Vinegar of Bloodroot. Preparation. — Take of Bloodroot, in powder, four ounces; Distilled Vinegar, two pints. Macerate the Bloodroot with the Distilled Vinegar, in a close glass vessel, for seven days ; then express the liquor, filter, and add to the filtered product, Alcohol one fluidounce. History.—In this preparation, Diluted Acetic Acid may be used as a substitute for the Distilled Vinegar. When kept well corked and in the dark, it may be preserved for a long time. Properties and Uses. — Vinegar of Bloodroot is seldom used as an emetic, except in combination with other agents of this class. Its chief employment internally is as an expectorant, hepatic, and alterative. As an external application it is useful in many cutaneous affections. Dose, from ten to thirty drops, in some mucilage or syrup, and repeated three or four times a day. Acetum Scillae. Vinegar of Squill. Preparation.—Take of Squill, sliced or bruised, four ounces; Dis- tilled Vinegar, two pints. Macerate the Squill with the Distilled Vinegar, in a close glass vessel, for seven days; then express the liquor, and set it by that the dregs may subside ; lastly, pour off the clear liquid, and add Alcohol one fluidounce. -5Ctherea. 1007 History.—In this preparation, Diluted Acetic Acid may be used as a substitute for the Distilled Vinegar. When either of the above prepara- tions are made with Diluted Acetic Acid, the addition of the Alcohol may be omitted. The Vinegar of Squill, when long kept, deposits, according to Vogel, a precipitate of citrate of lime and tannic acid. Properties and Uses.—Vinegar of Squill contains all the medicinal virtues of the Squill. It is frequently prescribed as a diuretic and ex- pectorant in several forms of dropsy, and in pulmonary affections. The syrup and oxymel are generally preferred, as they are less unpleasant to the taste, and do not decompose so soon. The dose is from half a fluidrachm to two fluidrachms; vomiting is likely to be caused by the latter quantity. It should be given in cinnamon-water, mint-water, or some other aromatic liquid calculated to conceal its taste, and obviate its nauseating effect. Its principal use, however, is in making the Syrup of Squill, which see. ^ETHEREA. Ethers. Ethers are liquids resulting from the action of acids on alcohol. They are of a very volatile and inflammatory nature, possessing a peculiar fragrance, with some sweetishness, and vary in composition, according to the acid employed in generating them. On account of their highly inflammable character, too much care cannot be taken to avoid decanting them near a flame, as in the vicinity of a lamp, candle, or gas-light. They require to be kept in accurately stopped bottles, and in a cool place, otherwise considerable loss may ensue in consequence of their evaporation. Chemists admit three kinds of ethers, viz., 1. Those con- sisting of etherine and water, or where the acid does not enter into the composition of the ether generated, but merely acts as a chemical agent on the alcohol; of Avhich we have an example in sulphuric ether. 2. Those consisting of an acid, etherine, and water, as in the case of hyponi- trous ether. 3. Those consisting of an acid and etherine only, as with muriatic or hydrochloric ether. Of these the first two are more gene- rally used in medicine. ./Ether Aceticus. Acetic Ether. Acetate of Oxide of Ethyle. Preparation. — Acetic ether may be formed by several processes, amono- which may be named the following : 1. Mix one hundred parts of Alcohol (sp. gr. 0.83} with sixty-three parts of concentrated Acetic Acid, and seventeen parts of strong Sulphuric Acid, and distil one hundred and taenty-fi.ve parts into a receiver, kept cold with wet cloths. 2. Distil a mixture of ten parts of Acetate of Soda, sixteen of Sulphuric Acid, and six of Alcohol. Rectify the product over lime and chloride of calcium. 3. Distil to dryness, a mixture of three parts of Acetate of Potassa, three of Alcohol, and two of Sulphuric Acid, and mix the distilled product with 1008 Pharmacy. one-fifth of sulphuric acid, and distil a second time an amount of ether equal to the alcohol employed. It may also be obtained by distilling any sulphovinate Avith strong acetic acid ; the acetic acid is brought in contact with nascent ether, and combines Avith it. History. — Acetic ether is a colorless liquid, of a refreshing, very grateful odor, and a peculiar, agreeable taste. It boils at 160°, and its specific gravity is 0.866. It does not decompose by keeping, but is easily changed by alkalies, yielding an acetate and alcohol; acids also decompose it. It is very combustible, burning readily when brought into contact Avith flame, at the same time, diffusing an acid odor. It is always present, in small quantity, in wine vinegar, which oavcs its flavor to this compound. It dissolves in seven and a half parts of water, and unites with alcohol in all proportions. It consists of one equivalent of acetic acid 51, one of etherine 28, and one of water 9=88. Its formula is given as Ct H> O+Ci H3 Os, and by Gregory as Ae 0, Ac 03. Properties and Uses. —Acetic ether is stimulant and antispasmodic, and is occasionally used to fulfill these indications. Sometimes it is applied externally, by frictions, to relieve rheumatic and neuralgic pains, and as a resolvent. The dose is from fifteen to thirty drops, sufficiently diluted with water. tEther Hydriodicus. Hydriodic Ether. Preparation.—Mix four parts of Iodine with ten parts of Alcohol 38°. Add little by little one part of Phosphorus, and submit the whole to dis- tillation. When the larger part of the alcohol has distilled over, add three parts more, and distil to dryness. The product of the distillation is mixed Avith water to separate the alcohol from the ether, which last is then rectified from chloride of calcium. History.—Hydriodic ether has no acid reaction. Its odor is ethereal, its taste pungent, but less sharp than that of sulphuric ether. Its den- sity is 1.9206 at 72° F. ; it boils at 110° F., and is not inflammable. When throAvn on burning coals, it expands in purple vapors. It is not decomposed immediately by potassa, nor by nitric or sulphurous acids, but sulphuric acid decomposes it, and sets free a part of the iodine. The action of the air discolors it slightly by liberating a little iodine, which may be readily removed by the alkalies, or mercury, a globule of which thrown into the vial, is sufficient to retain the ether in a state proper for inhalation. Its density admits of its being kept under water, in which it is insoluble. Its formula is Ci Ha I. Properties and Uses.—Hydriodic ether, is recommended by Dr. Huette, by way of inhalation, as a remedial agent in several diseases, especially in pulmonary consumption, tubercular affections in any part of-the body, and where it is desired to saturate the system quickly Avith iodine ; it appears likely to play an important part in medicine. Fifteen to thirty grains of the hydriodic ether are transferred, by means of a graduated ^Etherea. 1009 pipette, into a little ground stoppered bottle, (3 or 4 centimetres) an inch to an inch and a half high. The ether is covered with a stratum of water about two or two and a half millimetres thick, the object of which is to moderate the evaporation; when the vial is applied to one of the nostrils, and the air contained Avithin it is drawn by an inspiration. The ethereal vapor is sufficiently diluted with air before reaching the lungs. The evaporation of the ether may be accelerated by inclining the vial to one side, so that the continuity of the watery layer may be broken ; and the heat of the hand may be applied to the same object. Fifteen or twenty inspirations suffice for the impregnation of the system with iodine, and a quarter of an hour after the cessation of the inhala- tions, iodine is found in the urine, and has also been found present in fifty or sixty hours afterward. The physiological effects of this ether, are said to be, " After some inhalations, an impression of calmness and satisfaction announces that the hydriodic ether acts at first conformably with the sedative properties of the other ethers employed in medicine. The respirator)' motions are carried on with a readiness and fullness, advantageous to the circulation; but the antispasmodic action of the ethereal vapor which favors the absorption of the remedy, is soon followed by the influence of the absorbed iodine. The increase of vigor ceasing to be limited to the thoracic muscles, extends to the muscular system. The appetite is developed, the secretions are increased, the genital feelings become more sensitive, the pulse acquires fullness, and the vivacity of the feelings, and the activity of the intellect, prove that the impulse given to the other organs extends to the brain also. Such are the effects that four daily inhalations of ten minutes each produced on Dr. Huette. As to accident, he never experienced anything but a little corvza, and fre- quently Avhen the vapor has been too concentrated, a slight feeling of pressure in the temples." He thinks, that in many cases there will be an advantage in substi- tuting the inhalation of hydriodic ether, for the other preparations of iodine, observing that inhalation permits the fraclioning of the doses to any extent, and causes the absorption of the medicine by more extended surfaces, more generally accessible in all their parts, and better calcu- lated for the absorption of the smallest medicinal atoms, than are the digestive organs. Spiritus ^Etheris Nitrici. Sweet Spirit of Nitre. Spirit of Nitric Ether. Solution of the impure Hyponitrite of Oxide of Ethyle in Alcohol. Preparation. — Mix, in a large glass retort, Nitrate of Potassa, in coarse powder, two pounds, with Alcohol nine pints and a half; then gra- dually pour in Sulphuric Acid a pound and a half, and digest with a gentle heat for two hours ; then raise the heat and distil a gallon. To the distilled liquor add Diluted Alcohol a pint, and Carbonate of Potassa one ounce, and again distil a gallon.— U. S. 64 1010 Pharmacy. History.—The officinal spirit of nitric ether is composed of hyponitrous ether and rectified spirit, in variable proportions. When a reaction is effected between alcohol and nitric acid, directly, or between alcohol and the ingredients from which nitric acid may be generated, as from nitre and sulphuric acid, the result is always hyponitrous ether ; but when the ingredients for forming the ether hold alcohol in excess, this distils over with the ether, forming the spirit of nitric ether. In the process for preparing this ether, given above, the sulphuric acid being gradually added to the mixture of nitre and alcohol in the retort, and a gentle heat applied, nitric acid is evolved, which reacting upon a portion of the alcohol, generates the hyponitrous ether. When the temperature is subsequently increased, the ether, together with the remaining alcohol, passes over as the SAveet spirit of nitre, holding a portion of acid in the solution, from which it is purified by the last dis- tillation from carbonate of potassa. The object in adding the diluted alcohol previous to the last distillation, is, that a quantity of the spirit of nitric ether may be obtained, equal to that procured by the first distilla- tion Avithout reducing the mixture in the retort to dryness, and thereby give rise to the formation of empyreuma. Were the alcohol and sul- phuric acid to be first mixed together, instead of the alcohol and nitre, ordinary sulphuric ether would probably be generated, and the addition of the nitre Avould not give rise to the desired spirit of nitric ether. In conducting this process the retort should be of sufficient capacity to hold double the amount of articles employed. Spirit of nitric ether, according to its strength, is either colorless or of the lightest straw color. When properly prepared it is a colorless, volatile liquid, requiring to be kept in well stopped bottles, possessing a peculiar and fragrant ethereal odor, some-Avhat resembling that of apples, and a pungent, sAveetish, cooling, sharp taste ; its specific gravity is between 0.834 and 0.837, and it boils, when heated by means of a water bath, at 160°. It gradually becomes acid by long keeping, in which state it becomes unfit for medical use, on account of its chemical reac- tions Avith other substances with which it may be united, in many in- stances greatly impairing the efficacy of the mixture ; these effects may be obviated by keeping the sweet spirit of nitre standing on crystals of bicarbonate of potassa. It is very inflammable and burns Avith a whitish flame. It reddens litmus paper, but does not effervesce with carbonate of soda, unless it becomes acid. It is soluble in alcohol or Avater in all proportions. SAveet spirit of nitre is very subject to impurities. When it is the product of a too long continued distillation, it contains at first, aldehyd, which subsequently becomes, by the absorption of oxygen, acetic acid. Aldehyd may be detected by the addition of a weak solution of potassa, which forming an aldehyd resin, communicates a yellow tint to the liquid containing it, in addition to which a pungent odor, with acridity will be ^Etherea. 1011 observed. An equal volume of sulphuric acid added to sweet spirit of nitre hardly affects it if good; but if much aldehyd be present, the mixture will become dark-colored. Acids may be detected by the effer- vescence of the preparation when the alkaline carbonates or bicarbonates are added to it. Alcohol and Avater are frequently added to sweet spirit of nitre, thereby very much impairing its value ; it is extremely difficult to detect these adulterations. Properties and Uses.—Sweet spirit of nitre is a stimulant, antispas- modic, diuretic and diaphoretic. It is considered useful in dropsy associated Avith diseased heart, more so than when connected with dis- eased kidney; being a stimulant diuretic, it is best adapted to asthenic Conditions. In dropsy it may be advantageously combined with other diuretics, as syrup of squill, acetate of potassa, nitre, bicarbonate of potassa, or tincture of digitalis. It is useful in strangury, and is a good addition to copaiba as a diuretic for diluting the acrimony of the urine. It is often used in febrile affections, either alone or in conjunction with sedative or diuretic agents, for the purpose of inducing diuresis and diaphoresis. If the preparation becomes old, nitrous acid is, probably, formed, and when taken internally, it will give rise to pain in the stomach and griping. Spirit of nitric ether is a narcotic poison ; the accidental inhalation of its vapor during sleep, has occasioned death. Dose, from half a fluidrachm to two fluidrachms, three or four times a day in Avater, or according to the indications to be fulfilled. Off. Prep.—Mistura Copaibae Composita. ./Ether Sulphuricus. Sulphuric Ether. Oxide of Ethyle. Preparation. — Gradually add in an open vessel, fourteen, fluidounces of Sulphuric Acid, to Alcohol two pints, stirring them together fre- quently. While still hot, pour the mixture into a glass tubulated retort placed upon a sand-bath, and connected by a long adapter Avith a receiver kept cold by ice or iced Avater; then raise the heat quickly until the liquid begins to boil. When about half a pint of the ethereal liquid has passed over, gradually introduce into the retort through a tube reaching nearly to its bottom, Alcohol two pints previously mixed with Sulphuric Acid two fluidounces. Care must be taken that this mixture flow in a continuous stream, and in sufficient quantity to supply the place of the liquid which distils over; this may be accomplished by having the tube through which it flows furnished with a stop-cock to regulate the size of the current — the tube itself being passed through a cork accurately fitted into the tubulure. Then continue the distillation until about three pints have passed over, or until white vapors appear in the retort. To this distilled product add Potassa six drachms, previously dissolved in Distilled Water three fluidounces, and shake them frequently. At the end of twenty-four hours pour off the supernatant liquid into a retort, and with a gentle heat redistil it, until two pints of ether shall have 1012 Pharmacy. passed over, or until the distilled liquid becomes of the specific gravity 0.750.— U. S. History.—Ether is formed from the action of sulphuric acid upon alco- hol, and consists of four equivalents of carbon, five of hydrogen, and one of oxygen; its proximate constituents may be considered to be one equivalent of etherine, and one of water. It is commonly but impro- perly called Sulphuric Ether, probably on account of the sulphuric acid employed in its preparation; but no sulphuric acid enters into its com- position, and the action of other acids on alcohol, will, it is stated, pro- duce an identical ether. The view taken of the formation of ether has been that, as alcohol is a hydrated oxide of ethyle, and ether, oxide of ethyle Avithout Avater, the abstraction of the water from alcohol is all that is required to convert it into ether. To effect this removal of the water from alcohol, sulphuric acid is employed on account of its great affinity for water. The action, hoAvever, of the acid, is not direct but intermediate ; when two equivalents of sulphuric acid are mixed with one equivalent of alco- hol, the bi-sulphate of oxide of ethyle (sulphovinic acid), is formed, or a double sulphate of ether and Avater. When this is heated to about 285°, and the liquid kept in steady ebullition, it becomes decomposed, and the sulphuric acid seizing upon the water, prevents the ether from reuniting with it to reproduce alcohol, and the ether consequently dis- tils over, leaving two equivalents of sulphuric acid with one of water in the retort, and one equivalent of ether in the receiver. Ether, has, however, been produced without distillation, or the forma- tion of the bi-sulphate of oxide of ethyle, by using a larger proportion of alcohol than is commonly emploj'ed, and causing the reaction to take place in glass tubes sealed and exposed for a short time to a temperature of 320°. From which it appears that the theory above given is a ques- tionable one. In the formula above given for the preparation of ether, the process is to be commenced by using only a part of the alcohol, and Avhen de- composition has ensued and a portion of ether distilled over, the remain- der of the alcohol is to be gradually added, so as to replace that which, during the progress of the distillation, is constantly disappearing by its conversion into ether. If, instead of this course, the whole of the alco- hol were added at the first, a large portion of it would distil over with the ether. The small amount of acid added to the last portion, is deemed advantageous, on account of the weakness effected in the acid in the retort. The appearance of the white vapors during the distillation is indicative of the commencement of new reactions unlike those which generate the ether. However carefully the process may have been con- ducted, the ether is usually impregnated with sulphurous acid, heavy oil of Avine, alcohol, and water, and consequently its purification becomes necessary. This is accomplished by the addition of potassa for sulphu- ^Ethera. * 1013 rous acid and water, and water for alcohol, agitating the crude ether with the purifying agent, and redistilling at a gentle heat. Ether is a colorless, very mobile, highly refracting liquid, having a penetrating and sweet odor, and a cooling, pungent, aromatic taste. When pure it has the specific gravity 0.713, boils at 95°, forming a vapor of the density 2.586. It does not freeze at 160° below zero. When imperfectly prepared or too long kept, it reddens litmus paper, but not Avhen pure. It is very combustible, and its vapor is apt to form dangerous explosive mixtures with air. When slowly oxidized, it yields aldehyde, aldehydic acid, acetic and formic acids. For medicinal purposes the density should not be greater than 0.750. It is extremely volatile, evaporating speedily in the open air with the production of much cold. It is highly inflammable, on which account it should never be brought near a lighted candle, or other flame; water and carbonic acid are the products of its combustion. It is decomposed by too long keeping, and is partly converted into acetic acid. Iodine and bromine are dissolved by it, and sulphur and phosphorus sparingly. It also dissolves fixed and volatile oils, many resins and balsams, caout- chouc, tannic acid, and most of the organic vegetable alkalies. It differs from alcohol in not dissolving potassa or soda ; and it unites with alcohol in all proportions. Dr. C. F. Schonbein states that if a little pure ether be put into a bottle filled with pure oxygen or atmospheric air, and exposed to dif- fused light, the bottle being occasionally shaken, the ether, after the lapse of four months, will have acquired new properties. Although pro- ducing no action upon blue litmus paper, it will discharge the color of solution of indigo, convert pure phosphorus, Avhen immersed in it, into phosphorus acid, eliminate iodine from iodide of potassium, change pure sulphate of protoxide of iron to the basic and acid sulphate of the deu- toxide, transform yellow prussiate of potassa into the red salt, convert sulphuret of lead into the sulphate, etc. Similar effects are produced with oil of turpentine and oil of lemons, when treated in the same way as the ether. He expresses an opinion that the property which these substances thus acquire, is due to the presence of oxygen in a chemically exalted condition. Ether is frequently impure from the presence of foreign substances. If the impurity be an acid, it may be detected by litmus paper, and removed by agitation Avith potassa; if fixed substances are present, they will remain upon the evaporation of the ether. If heavy oil of wine is the impurity, it may be known by the milky appearance of the ether upon being agitated with Avater. In the officinal ether a portion of alcohol is generally present, but if there be too large a proportion of it, it will increase the density of the ether to too high a point. When this is the case, the alcohol may be removed by agitating the ether with twice its bulk of water; this fluid unites with the alcohol, and upon resting, forms 1014 Pharmacy. a heavy layer upon which the ether floats. The latter may be poured off, and purified by agitation with fresh burnt lime, and subsequent dis- tillation. Properties and Uses.—Ether is a powerful diffusible stimulant, and ia likewise possessed of narcotic, antispasmodic, and expectorant properties. When applied externally, and allowed to evaporate, it acts as a refriger- ant ; but if its evaporation be repressed, it becomes a powerful rubefa- cient, and even vesicant. As a stimulant and antispasmodic it is used beneficially in low fevers attended with subsultus tendinum, nervous headache, cramp of the stomach, fainting, asphyxia, flatulent colic, gastrodynia, hysteria, asthma, dyspnoea, palpitation, and gout of the stomach; it is also efficacious when given alone, or in combination with oil of turpentine, in relieving the pain and spasm caused by the passage of biliary calculi. As an antispasmodic, it will be found useful in all forms of spasmodic action, unattended by inflammation, as chorea, epi- lepsy, tetanus, etc. The dose of ether is from ten to sixty drops, to be frequently repeated when the full effect of the remedy is desired. When applied locally as a refrigerant, allowing it to evaporate, it is useful in nervous and other headaches, in external inflammations, strangulated hernia, etc. As a rubefacient, it may be employed in all cases where this effect is indicated, by checking its evaporation. The virtues of many agents containing vegetable oils and resins, may be taken up by ether in the form of tincture, when, by evaporating the ether, the desired active product is left behind; this is the case with lobelia seeds, capsicum, Scutellaria, podophyllum, ptelea, stillingia, xan- thoxylon berries, iris, and several other officinal preparations. Under the name of Letheon, ether is sometimes employed as an anaesthetic agent, for the prevention and removal of pain and spasm, and Avhenever severe operations are about being performed. It has also been employed in this manner, in severe dysmenorrhea, as Avell as during parturition. To use it, a soft sponge, hollowed out on one side, is saturated with pure ether—this is applied to the nostrils of the patient, and inhaled by him; at first a short cough is generally produced, which soon disappears, and in from two to five minutes, or Avhen about two fluidounces of ether have been expended, the anaesthetic effect takes place. A feeble and slow pulse during its use, or convulsions, indicate its discontinuance, and in the latter case, a free application of cold water. To produce anaesthesia chloroform is more commonly preferred. The practice of frequently inhaling ether is dangerous, often causing inflammation of the brain, or inanity. Off. Prep.—Lotio ^Etheris Composita. Preparations of Ammonia. 1015 PREPARATIONS OF AMMONIA. Ammonite Carbonas. Carbonate of Ammonia. Sesquicarbonate of Ammonia. Mild VolatUe Alkali. Preparation.—Take of Muriate of Ammonia a pound; Carbonate of Lime, (Chalk) dried, a pound and a half. Pulverize them separately, then mix them thoroughly, and sublime with a gradually increasing heat, from an earthenware retort, into a receiver kept cold.— U. S. History.—By the above process the following reactions happen; the muriatic acid unites with the lime, forming chloride of calcium and water, while the carbonic acid unites with the ammonia producing car- bonate of ammonia. During sublimation the carbonate and water pass off together as a hydrated carbonate of ammonia, and the chloride of calcium is left behind. The retort used in this process should have a wide cylindrical neck, and for the purpose of facilitating the extraction of the sublimate, the receiver should be cylindrical. One equivalent of chalk, and one of muriate of ammonia, mutually decompose each other, but, as in the above formula, when an excess of chalk is added it causes a perfect decomposition of the muriate of ammonia, without which, a portion of this latter salt would sublime also, and thereby ren- der the carbonate impure. On the large scale, carbonate of ammonia is prepared by sublimation of the materials employed, from an iron pot, into a large earthen or leaden receiver. It may be manufactured from sulphate of ammonia, and indirectly, from gas-liquor, and bone-spirit. Carbonate of ammonia is usually met with in white, translucent, fibrous and somewhat crystalline masses, moderately hard, of a power- ful ammoniacal odor, and a strong, penetrating, alkaline and ammoniacal taste. When exposed to the air, it gradually becomes opake and friable, loses ammonia, and falls to a powder of bicarbonate of ammonia. It is soluble in about four times its weight of cold Avater, and abundantly so in diluted alcohol; boiling water decomposes it, disengaging ammonia with effervescence. Acids decompose it, as do likewise the fixed alka- lies and their carbonates, lime-water, magnesia, solution of chloride of calcium, alum, acid salts, solutions of iron, corrosive sublimate, acetate, and subacetate of lead, and sulphates of iron, and zinc. It is sometimes, from faulty preparation, rendered impure by the pre- sence of the sulphate or muriate of ammonia; the former may be de- tected by the solution, when neutralized with nitric acid, giving a white precipitate with chloride of barium, and the latter, by the neutralized solution yielding a precipitate with nitrate of silver. If turmeric paper held over it, undergoes no change, it has passed into the bicarbonate. Carbonate of ammonia consists of two equivalents of ammonia 34.3, three of carbonic acid 66.36, and two of water 18=118.39. 1016 Pharmacy. Properties and Uses.—In large doses carbonate of ammonia is a pow- erful narcotic and irritating poison ; in small doses it is an energetic dif- fusible stimulant, diaphoretic, antispasmodic, and antacid. As a stimu- lant it is used in low stages of continued fever, in which it augments the action of the heart and arteries without producing an undue excitement of the brain, for which purpose it is also employed, as well as for its antacid properties, in atonic gout, and in derangements of the stomach arising from dissipation. In conjunction with guaiacum, it has proved beneficial in chronic rheumatism. It has also proved very beneficial in epilepsy, chorea, and scrofula, especially when attended with much acid- ity of the stomach. It has likewise proved serviceable in some cases of diabetes. It is rarely employed as an emetic in cases of paralysis in the dose of thirty or forty grains. It is much used as a stimulant in hysteria and fainting, combined Avith some aromatic oil, and known as Smelling Salts. Externally it is a gentle rubefacient, but is seldom em- ployed in this Avay. The dose is from five to twenty grains every three or four hours, in the form of pill, or dissolved in some aqueous vehicle. Ammonite Liquor. Liquor Ammoniae. Aqua Ammoniae. Solution of Ammonia. Water of Ammonia. Preparation.—Take of Muriate of Ammonia, in very fine powder, a pound; Lime, recently burnt, a ]->ound and a half; Distilled Water a pint; Water nine fluidounces. Break the lime in pieces, and pour the water upon it, in an earthen or iron vessel; then cover the vessel, and set it aside till the lime falls into powder, and becomes cold. Mix this thoroughly with the Muriate of Ammonia, in a mortar, and immediately introduce the mixture into a glass retort. Place the retort upon a sand- bath, and adapt to it a receiver, previously connected, by means of a glass tube, with a quart bottle, containing the distilled water. Then apply heat, to be gradually increased till the bottom of the iron vessel containing the sand becomes red-hot; and continue the process so long as the ammonia comes over. Remove the liquor contained in the quart bottle, and for every fluidounce of it add three and a half fluidrachms of Distilled water, or so much as may be necessary to raise its specific gra- vity to 0.96, and preserve it in small vials well stopped. Or it may be prepared by combining one part, by measure, of Stronger Solution of Ammonia, with two parts of Distilled Water.— U. S. History.—In the above process the muriatic acid of the ammonia having a greater affinity for the lime, combines with it forming chloride of calcium and water, while the ammonia is set free, and passes into the receiver, where it is absorbed by the water. With this absorption there is an augmentation of the bulk of the fluid in the receiver, hence the receiver should be larger than required to hold the exact amount of water. Equal weights of muriate of ammonia and lime are sufficient for the production of the ammoniacal gas, but by the addition of an Preparations of Ammonia. 1017 excess of lime, the complete decomposition of the muriate of ammonia is insured. Water is capable of absorbing 670 times its volume of ammoniacal gas at 50°, at the same time increasing its bulk about two-thirds. In the above process it contains about ten per cent, of ammonia. When prepared on a large scale, it is usually obtained from the sulphate of ammonia. Liquor ammonia is a colorless, strongly alkaline liquid, having a pecu- liar, pungent odor, and a caustic, acrid taste. It is incompatible with acids, acidulous, and most earthy and metallic salts, and is much used for various pharmaceutical purposes. The salts of lime, baryta, and strontia, are not decomposed by it, and those of magnesia only partially. Lime-water causes a precipitate if the ammonia be partly carbonated. Upon neutralizing it with nitric acid, it will yield no precipitate, if pure, with chloride of barium, carbonate of ammonia, or nitrate of silver; if the first occasions a precipitate, it indicates the presence of sulphuric acid, or a sulphate; if the second, earthy matter is present; and if the third produces a precipitate, muriatic acid, or a muriate is indicated. A large proportion of the liquor ammonia of commerce is obtained from coal-gas liquor, and is liable to contain pyrrol, naphtuline, and other im- purities. These may be distinguished by nitric acid, which reddens the solution, and by the liquor imparting a rich purple color to a strip of fir Avood, after having been previously supersaturated with muriatic acid. Properties and Uses. — Liquor ammonia is a powerful irritant and narcotic poison, producing in large doses tetanus and coma, and in smaller quantity inflammation or ulceration. In medicinal doses it is stimulant, sudorific, antacid, and rubefacient. It more especially stimu- lates the heart and arteries, without unduly exciting the brain. As an antacid it has been used in acidity of the stomach, sick-headache caused by acid stomach, heartburn, etc. It has likewise been used as a stimu- lant and antispasmodic in neuralgia of the face and head, asthma, pertussis, and delirium-tremens ; and is highly recommended as an internal stimulant in cases of retrocession of old and obstinate cutaneous eruptions. Applied to the nostrils, it is sometimes beneficial in syncope, asphyxia, hysteria, and similar affections ; and has been recommended as a rubefacient application to burns. It is employed externally in the form of liniment, combined with oils, as a rubefacient. I have used the liquor ammonia successfully in the treatment of hydrophobia, an account of which will be found in the Western Medical Reformer, Vol. VI, October, 1846, No. 4, page 83. The dose of liquor ammonia is from ten to thirty drops, largely diluted with water, to prevent its caustic influence on the mouth and throat. When SAvallowed undiluted, or in an overdose, it acts as a corrosive poison, and the best antidotes to 1018 Pharmacy. its dangerous effects are vinegar or lemon-juice, Avhich must be promptly administered; they act by neutralizing the ammonia. Off. Prep.— Linimentum Ammonite ; Linimentum Capsici Composi- tum ; Linimentum Saponis Camphoratum. Ammonite Liquor Fortior. Liquor Ammonite Fortior. Stronger Solution of Ammonia. Preparation.—The process for obtaining this is similar to that em- ployed in procuring the Liquor Ammonia, the difference consisting only in the specific gravities of the two solutions, that of the present stronger solution being 0.882. History.—Its properties are very similar to those of the Liquor Ammo- nia, being, however, more highly caustic, acrid, and alkaline. Its impurities are also similarly distinguished. In purchasing or preparing the solutions of ammonia, the apothecary should always ascertain their densities by the hydrometer ; the stronger solution should be 0.882, the officinal solution 0.96. Both of these solutions should be kept in small vials, and well stopped, as they rapidly lose their ammoniacal strength by contact with the atmosphere. Properties and Uses.—Undiluted, this solution of ammonia is entirely too strong for medicinal use. Its principal employment is externally as a rubefacient, vesicant, and caustic. The vesicating ammoniacal oint- ment of Dr. Gondret is prepared as folloAvs: melt together by a gentle heat, thirty-two parts of lard and two parts of oil of sweet almonds, and pour the melted mixture into a bottle Avith a wide mouth. Then add seventeen parts of solution of ammonia of 25°, and mix, with continued agitation, until the Avhole is cold. Preserve in ground- stopper bottles, and in a cool place. If well prepared, it will vesicate in ten minutes. Liquor Ammonite Acetatis. Ammonite Acetatis Liquor. Solution of Acetate of Ammonia. Spirit of Mindererus. Preparation.—Take of Diluted Acetic Acid a pint; Carbonate of Am- monia, in powder, a sufficient quantity. Add the Carbonate of Ammonia gradually to the Acid, stirring constantly, until effervescence ceases. The Diluted Acetic Acid, directed in this formula, is to be made by mixing together Acetic Acid (sp. gr. 1.041) a pint, with Distilled Water seven pints. This liquor may likewise be made by dissolving Carbonate of Ammo- nia one scruple, in Distilled Water seven fluidounces, and then gradually adding Acetic Acid, with frequent agitation, a sufficient quantity, until saturation, which is known by the cessation of effervescence. Owing to the unequal strength of the acetic acid of commerce, the latter is the more definite formula. History.—In this process the carbonate of ammonia is decomposed by the acetic acid, the carbonic acid being evolved with effervescence, Preparations of Ammonia. 1019 while the acid unites with the ammonia, forming an acetate of-ammonia; the result of this action is an aqueous solution of acetate of ammonia. The point at which saturation is reached may be ascertained by the alternate use of litmus and turmeric paper; and it is recommended to allow a slight acidity to prevail, which is OAving to a small amount of car- bonic acid being dissolved in the liquid, but which will become removed by time. Solution of acetate of ammonia is a transparent and colorless liquid, with scarcely any odor, and a faint, mawkish, saline taste, but bitter when it contains an excess of alkali. It is very apt to spoil, and hence should be made only in small quantities at a time. It may be readily known by setting free acetous acid on the addition of sulphuric, and by giving an ammoniacal odor on the addition of caustic potassa; solution of sulphate of iron renders it reddish-brown. When evaporated in vacuo, very deliquescent crystals may be obtained. The pure solution is not colored by hydrosulphuric acid, nor precipitated by chloride of barium. Sulphureted hydrogen occasions a black precipitate if copper or lead enters into the solution; nitrate of baryta causes a white precipi- tate if sulphuric acid be present; and nitrate of silver a white precipi- tate if muriatic acid be present. If the solution of acetate of ammonia is kept ready prepared in the shop, it should be left slightly acidulated; and when dispensed a small particle of carbonate of ammonia should be added to impregnate it anew with the carbonic acid gas which exhales by standing. Solution of acetate of ammonia is incompatible with acids, the fixed alkalies and their carbonates, lime-water, magnesia, sulphate of magne- sia, corrosive sublimate, the sulphates of iron, copper, and zinc, and nitrate of silver. Mr. W. S. Merrell recommends the following preparation as an elegant and pleasant anodyne, and diaphoretic in fevers, worthy the notice of the profession; he calls it Liquor Amnion. Acetat. et Morphiae: Take of Solu- tion of Acetate of Ammonia one fluidrachm; Acetate of Morphia one grain; Syrup of Lemon one fluidrachm; mix together. The dose is from half a fluidrachm to a fluidrachm, to be taken in water. Each fluidrachm contains one-eighth of a grain of acetate of morphia. Properties and Uses.—Solution of acetate of ammonia is diaphoretic and diuretic, and is used in febrile and inflammatory diseases. Ii proves diuretic Avhen the patient is kept cool, and diaphoretic Avhen he is kept warm. Externally, it has been used as an application, on hot flannel, to mumps, and likewise applied, by compresses kept constantly moist, in the hydrocele of children. In chronic ophthalmia, it forms an excellent collyrium, in the quantity of one fluidounce to seven fluidounces of rose- water, and two fluidrachms of laudanum. In porrigo of the scalp, it has been effectual, used as a lotion. The dose is from half an ounce to 1020 Pharmacy. one and a half fluidounces, every three or four hours, mixed with sweet- ened Avater. Off. Prep.—Lotio ^Etheris Composita. AQU^E MEDICATE. Medicated Waters. These consist of water variously impregnated with some medicinal substance; and as Eclectics occasionally employ them, a brief reference to them will be necessary. When water is distilled from aromatic plants, it acquires their peculiar flavor as well as a portion of their medicinal qualities; this is chiefly owing to the volatile oil of the plants rising Avith the aqueous vapor and condensing with it in the receiver; but from the incapability of water holding much oil in solution, these preparations are generally possessed of but little strength. The most simple and easy process for the prepa- ration of medicated waters, is to impregnate distilled water with the volatile oil by trituration with carbonate of magnesia, and then filtering; this course is now generally pursued in the preparation of most aromatic waters. The object of the carbonate of magnesia is to cause the oil to be more minutely divided, that it may present a larger surface to the action of the solvent. Other agents have been recommended for this purpose, as finely poAvdered glass or silica, porcelain-clay, and pumice- stone. It is very important that pure distilled Avater be used in the preparation of medicated waters, as any other may contain articles which will decompose or destroy the virtues of the oil. Aqua Acidi Carbonici. Carbonic Acid Water. Soda Water. Mine- ral Water. Artificial Seltzer Water. Preparation. — By means of a forcing-pump, throw into a suitable receiver, nearly filled with Avater, a quantity of Carbonic Acid Gas equal to five times the bulk of the water. Carbonic acid gas is obtained from powdered marble by means of dilute sulphuric acid.— U. S. History.—Under common atmospheric pressure, water takes up its volume of carbonic acid gas; if the pressure be doubled, the quantity of the gas absorbed will also be doubled, and so on. Consequently, in saturating the water as above, with five times its volume of carbonic acid gas, it must be subjected to a pressure of five atmospheres. Carbonic acid water is a sparkling liquid, having a pleasant, pungent, and slightly acidulous taste. It is known familiarly by the name of "soda Avater," or, when put up in bottles and mixed with syrups of various kinds, as " mineral water." The vessels which contain it should be kept in a cold place, and be perfectly tight, otherwise the gas will escape and the water lose its briskness. Too much care cannot be taken to avoid metallic impurities, especially of lead. The first daily Aqu^e Medicate. 1021 draught of carbonic acid water, from a fountain furnished with tubes of lead, should invariably be throAvn away, as its use might give rise to unpleasant symptoms. Carbonic acid, formerly called fixed air, is a colorless gas, of an odor someAvhat subacid and pungent, and a slight acidulous taste. It com- bines with salifiable bases, forming salts which are called Carbonates, and from which it is driven off by all the strong acids. It reddens litmus, although the blue color is restored by boiling, the gas being given off. It extinguishes flame, and is quickly fatal when inhaled. If a light be introduced into a well, pit, mine, or other place, it will burn dimly or be extinguished if this gas be present, and the air of such place will cer- tainly destroy life if respired. Its specific gravity is 1.527; and it is so much heavier than air that it may be poured from one vessel into another. The sparkling and effervescing properties of many kinds of wine, beer, cider, etc., are owing to the presence of carbonic acid gas. It is liquefied by a pressure of 36 atmospheres; and is solidified by removing the pressure, and allowing the gas, which almost instantly evaporates, to escape through a jet; this produces such a degree of cold as to freeze a part of the gas into a white solid like snow. When car- bonic acid has accumulated in cellars or other places, so as to render them fatal to animal life, it may be removed by sprinkling about some liquor ammoniac; this combines with the carbonic acid to form carbonate of ammonia, and fresh air rushes in to fill up the space produced by the condensation of the acid. It is composed of one equivalent of carbon 6, and tAvo of oxygen 16=22; its formula is CO2. Properties and Uses.—Carbonic acid water is diaphoretic, diuretic, and anti-emetic. It forms a pleasant drink in fevers, allaving thirst, lessen- ing nausea and gastric uneasiness, and promoting diuresis. It may be administered four or five times daily in doses of from three to six fluidounces. Aqua Ammonias. (See Ammoniae Liquor.) Aqua Amygdalae Amar^e. Bitter Almond Water. Preparation.—Rub Essential Oil of Bitter Almonds sixteen minims, with Carbonate of Magnesia one drachm, and gradually add, while con- tinuing the trituration, Distilled Water two pints; filter through paper. History.—This preparation is very liable to spontaneous decomposi- tion, and should, therefore, be prepared only in small quantities at a time, or as required for use. If a drop of sulphuric acid be added to a pint of the mixture, and it be kept closely stopped and excluded from the light and air, it may be preserved for a long time. This is a pre- ferable preparation to that made by distilling bitter almonds with water, which is much stronger than that made according to the above formula, and has been prescribed with fatal effects. 1022 Pharmacy. Properties and Uses.—It is a sedative, affecting the system similarly to medicinal hydrocyanic acid, and has been employed alone, and in combination with other agents, in nervous cough, and various spas- modic affections. The dose of it, when freshly made, is two fluidrachms, which may be carefully and gradually increased to six or eight fluidrachms, and Avhich may be repeated two or three times daily. Aqua Calcis. Lime-Water. Preparation.—Add about four ounces of Unslaked Lime to Distilled Water one gallon. Stir it up well, and then set it aside for three or four hours. Then pour off the clear liquor as it may be wanted. History.—This is a solution of lime in water, and may be made with pure spring or river water, instead of distilled water. Water dissolves but a very small proportion of lime, and in larger quantity when cold than when hot; hence the propriety of employing cold water in the pro- cess. Lime-water is colorless, inodorous, and of a disagreeable alkaline taste; it forms an imperfect soap with oils, and changes vegetable blues to green. It attracts carbonic acid from the atmosphere, Avith the for- mation of carbonate of lime, on which account it should be kept in closely stopped bottles, or what is more convenient, in bottles containing an excess of lime. Properties and Uses. — Lime-water is antacid, anti-lithic, tonic, and astringent. It has been recommended in epilepsy, palpitation of the heart, and spasmodic diseases generally, accompanied with acidity of stomach, also in painful affections of the stomach dependent on disor- dered digestion, as pyrosis and gastrodynia. It is likeAvise beneficial in chronic dysentery and diarrhea, and diabetes, especially Avhen given in combination with a decoction of white oak-bark. In dyspepsia, phthisis, and other forms of disease, where from acidity of the stomach the usual food is rejected, or if retained gives rise to much uneasiness and unplea- sant symptoms, one part of lime-water added to three parts of good SAveet milk, has been found useful both as medicine and diet. A table- spoonful of lime-water will often allay vomiting. It has been advan- tageously used as an injection in gleet, gonorrhea, leucorrhea, ulceration, and increased discharges from the bladder; in all instances during the absence of inflammation. Externally, it has been applied as a Avash in tinea capitis, scabies, foul and gangrenous ulcers, and when mixed with linseed oils forms a liniment of much value in burns and scalds. It has frequently been employed as a vermifuge in combination with worm- seed oil, or some other anthelmintics. If its use be too long continued, it debilitates the stomach. An overdose produces unpleasant symptoms; the remedies for which are bland and mucilaginous drinks. The dose of lime-water is from four fluidrachms to four fluidounces; it is best taken in an equal measure of milk. Off. Prep.—Linimentum Calcis. Aqu^e Medicate. 1023 Aqua Camphorae. Camphor Water. Preparation. — Triturate Camphor two drachms with Alcohol forty minims, then add Carbonate of Magnesia four drachms, and continue the trituration, and finally, gradually add Distilled Water two pints; when all is well rubbed together, filter through paper. History.—By the above process one fluidounce of water is made to contain over three grains of camphor. The first trituration with the alcohol, deprives the camphor of its cohesiveness, and renders it more readily pulverizable, and the subsequent trituration with carbonate of magnesia effects a very minute division of it, so that a permanent solu- tion of camphor is obtained, of sufficient strength to exert an influence on the system. The filtration separates the magnesia. Properties and Uses.—Camphor water is chiefly used in low fevers and typhoid conditions, for the purpose of quieting restlessness and other symptoms of nervous derangement or debility. It has also been em- ployed to allay uterine after-pains, and in all cases where camphor is indicated. The dose is from half a fluidounce to two fluidounces repeated every one or two hours. Off. Prep.—Mistura Camphorae Composita. Aqua Cinnamomi. Cinnamon Water. Preparation.—Triturate Oil of Cinnamon half a fluidrachm with Car- bonate of Magnesia a drachm, and then with Distilled Water two pints, to be gradually added ; finally filter through paper. Properties and Uses. — Cinnamon water should be cautiously used in inflammatory complaints. It is useful in passive hemorrhage from the lungs, stomach, kidneys, or uterus, and in chronic diarrhea and dysen- tery; and is much employed as a vehicle for other less agreeable medicines. It will sometimes allay vomiting. The dose is from two fluidrachms to two fluidounces. Aqua Destillata. Distilled Water. Preparation.— In a clean retort kept only for this purpose, place Water ten gallons. First distil two pints and throw them away; then distil eight gallons. Keep the Distilled water in glass bottles, well stopped. History.—Distilled water, although not a medicated water, is intro- duced here, partly to avoid a separate place for it, and partly on account of its extensive employment in the preparation of medicated waters. For medicinal purposes, distilled water should undergo no change by sul- phureted hydrogen, nor on the addition of tincture of soap, subacetate of lead, chloride of barium, oxalate of ammonia, nitrate of silver, or lime- water, and should evaporate without residue. In many pharmaceutical and chemical processes, distilled Avater is very essential, while in others pure spring or river, or rain Avater will be sufficient. As the first portion of 1024 Pharmacy. water which comes over during distillation is apt to contain carbonic acid, or other volatile impurity, it is commonly rejected. For the pro- perties and uses of Avater, see Aqua in Part I. Aqua Mentha Piperita. Peppermint Water. Preparation. — Triturate Oil of Peppermint half a fluidrachm, with Carbonate of Magnesia a drachm, then Avith Distilled Water two pints, to be gradually added ; finally, filter through paper. Properties and Uses.—Peppermint water is used as an antispasmodic and carminative, in flatulence and flatulent colic, to allay nausea and A'omiting, and as a gentle aromatic stimulant. The dose is from four fluidrachms to two fluidounces, three or four, or more times a day. Off. Prep.—Mistura Camphorae Composita. Aqua Mentha Viridis. Spearmint Water. Preparation.—Triturate Oil of Spearmint half a fluidrachm, with Car- bonate of Magnesia a drachm, then with Distilled Water two pints, to be gradually added; finally, filter through paper. Properties and Uses.—Similar to those of peppermint water, to which some persons prefer it. The dose is also the same. Off. Prep.—Mistura Camphorae Composita. Aqua Picis Liquids. Tar Water. Preparation.—Take of Tar two pints, Boiling Water a gallon. Mix together, and stir with a wooden rod for fifteen minutes. When cold, and the tar has subsided, strain the liquor and keep it in well stopped bottles. Properties and Uses.—Tar Avater is stimulant and diuretic, and exerts an influence more especially on mucous membranes, hence it has been found useful in chronic catarrhal and urinary affections, in doses of one or two pints daily. Sometimes tar Avater is prepared in pulmonary affec- tions, as above-named, Avith an addition of Honey two pints. Externally, it is useful as a Avash in several chronic cutaneous diseases. Aqua Piment^e. Pimento Water. Preparation.—Triturate Oil of Pimento two fluidrachms, with PoAvdered Silex two drachms, then with Distilled Water one gallon, to be gradually added ; finally, filter through paper. Properties and Uses.—Carminative in the dose of one or two fluid- ounces. Aqua Hedeom,e Pulegioides. Pennyroyal Water. Preparation.—Triturate Oil of American Pennyroyal half a fluidrachm, with Carbonate of Magnesia a drachm, then with Distilled Water two pints, to be gradually added ; finally, filter through paper. Properties and Uses. — Pennyroyal water may be used for the same purposes and in the same doses as peppermint and spearmint waters, to which some persons prefer it. Cataplasmata. 1025 Aqua Ros^e. Rose Water. Preparation.—To the fresh petals of Hundred-leaved Roses eight pounds, add Water two gallons. Distil one gallon. History.—When thus prepared rose water has the fragrance of the rose in great perfection ; but is liable to spoil by long keeping, especially if exposed to the action of light and air. It may also be prepared in the same manner as pursued for Cinnamon Water; or by distilling together water and the oil of roses. Properties and Uses.—Rose water is destitute of any irritating proper- ties, and is much used in collyria and other lotions, chiefly on account of its agreeable odor; applied to the eye, it has a slightly stimulating and cooling influence. Aqua Sambuci. Elder Flower Water. Preparation. — To Fresh Elder Flowers ten pounds, add Water two gallons, distil one gallon. Elder flowers yield very little oil; the Avater distilled from them is sometimes used in collyria and other lotions. N. B. Medicated Waters are frequently mau by adding to a few pounds of the leaves or flowers of the article required, six or seven fluid- ounces of proof spirit, and two gallons of water; from which one gallon is distilled. In this way was formerly obtained nearly all of these preparations, but the processes given above, are now esteemed the best. Aqua Florum Aurantii, Orange Flower Water, Aqua Fceniculi, Fennel Water, Aqua Menthee Piperitae, Peppermint Water, Aqua Mentha) Viri- dis, Spearmint Water, together with several others may be procured from the plant or flowers, by the mode of distillation just referred to. CATAPLASMATA. Cataplasms. Cataplasms or poultices are substances intended for local application; they are always moist, and of a consistence not to adhere firmly to the skin, nor to spread over the parts adjacent to their application. They are of various kinds ; some are discutient, others favor suppuration ; some again are refrigerant, and others emollient, or stimulating. They are usually applied tepid or warm, and should not be allowed to dry previous to being renewed. Cataplasma Carbonis. Charcoal Cataplasm. Preparation.—Macerate Bread, two ounces, with Water ten fluidounces, for a short lime near the fire ; then gradually add and mix with it Pow- dered Flaxseed ten drachms, stirring so as to make a soft cataplasm. With this mix Powdered Charcoal two drachms, and when prepared for application, sprinkle one drachm of charcoal on the surface of the cata- plasm. 65 1026 Pharmacy. Properties and Uses.—As recently prepared charcoal absorbs the prin- ciples on which the offensive odor of putrid animal matter depends, this cataplasm will be found an excellent application to foul and gangrenous ulcers, correcting their fetor, and improving their condition. It should be renewed two or three times in every tAventy-four hours. Cataplasma Dauci. Carrot Cataplasm. Preparation.—Take of Garden Carrots, scraped, four ounces, Indian- meal one ounce, Boiling Water a sufficient quantity to form a cataplasm of the proper consistence. Properties and Uses.—This will be found a valuable application to indolent and gangrenous ulcers, and painful tumors. Cataplasma Fermenti. Yeast Cataplasm. Preparation.—To one pint of Milk, tepid, add Yeast four fluidounces, and fine Slippery Elm bark a sufficient quantity to form a cataplasm of the proper consistence. Properties and Uses.—This is valuable as an antiseptic application. It will be found especially serviceable in gangrenous ulcerations, the fetor of Avhich it corrects, while it hastens the suppuration of the slough. Cataplasma Lini. Flaxseed Cataplasm. Preparation.—To Boiling Water ten fluidounces, add gradually, Pow- dered Flaxseed four ounces and a half, or a sufficient quantity ; stir con- stantly, so as to make a cataplasm. Properties and Uses.—This forms a convenient emollient poultice, to relieve the tense condition of the vessels in inflammation, and to promote suppuration. Fresh lard, or olive oil spread over its surface, will pre- serve its softness, and prevent it from adhering to the skin. Cataplasma Lobeliae. Lobelia Cataplasm. Preparation.—To equal parts by weight of Powdered Lobelia and fine Elm bark, add a sufficient quantity of weak Ley, Avarm, to form a cataplasm. Properties and Uses.—This forms an excellent application to felons, white-swelling, wounds, fistula, inflammation of the breast and other parts, stings of insects, erysipelatous inflammations, and painful swellings or ulcerations. It should be frequently renewed. Cataplasma Oxycocci. Cranberry Cataplasm. Preparation. — Take of ripe Cranberries any quantity, and bruise them to form a cataplasm. Properties and Uses.—Applied around the throat in quinsy, and in swelling of the glands of the throat in scarlatina and other diseases, I know of no more useful agent; its action is very prompt, relieving in a few hours. It has been likewise reputed useful in cancerous ulcers, ery- sipelatous inflammations, and gouty-rheumatism. Cerata. 1027 Cataplasma Phytolacca. Poke-root Cataplasm. Preparation.—Place fresh Poke-root in hot ashes to roast, when suffi- ciently done, mash it, and form a cataplasm. Properties and Uses.—This may be applied to all kinds of tumors in order to discuss them; or if they be too far advanced, it will hasten suppuration. In the latter instance its action is accompanied with much pain. It is especially valuable in tumors of an indolent character, as bubos. It should be renewed two or three times a day. Cataplasma Stramonii. Stramonium Cataplasm. Preparation.—Take of the fresh Leaves of Stramonium any quantity, bruise them, and add a small quantity of hot Water to form a sufficiently moist cataplasm. Properties and Uses.—I have found this a decidedly efficacious appli- cation in peritoneal inflammation, the whole abdomen is to be covered with it; likewise in acute rheumatism, and in gastro-intestinal inflamma- tions. Applied to the perineum in enlargement of the prostate, for the purpose of securing the passage of the catheter in case of retention of urine, when it cannot otherwise be entered into the bladder, I know of no better agent—it should remain on the parts about an hour, before attempting the introduction of the catheter. It will be found valuable in all rheumatic or neuralgic pains. Cataplasma Ulmi. Elm Cataplasm. Preparation.—Take of Powdered Elm bark a sufficient quantity ; stir it in hot Water, or Milk and Water, to the consistence of a cataplasm. Properties and Uses.—This cataplasm is of almost universal applica- tion, and is superior, in many respects, to every other. As an applica- tion to painful swellings, inflammations, ulcerations, and to facilitate the separation of the slough produced by caustics, and for various other purposes, it stands, and justly too, in high repute among Eclectic physi- cians. CERATA. Cerates. These are substances of an unctuous character, and are usually com- posed of lard or oil combined by means of heat with wax, spermaceti, or resin, and to which various medicinal agents are often added. They have a consistence between those of ointments and plasters, and at the ordinary temperature of the atmosphere, are capable of being spread upon linen or leather, by means of a spatula ; and when applied to the surface of the body, they do not melt or run. In the preparation of cerates, the apothecary should be very cautious not to employ oil or lard which pos- sesses the slightest degree of rancidity; fresh and sweet articles of this 1028 Pharmacy. kind must alone be used. A gentle heat will be sufficient to effect the fusion, and this is best obtained by means of a water bath; and when the mixture is cooling, it should be constantly stirred, and the portions which concrete on the sides of the vessel should be removed from time to time, and mixed thoroughly with the more fluid portion, until the whole attains the proper consistence. In the preparation of a large quan- tity of cerate, it is better to heat the vessel in which the cooling takes place, previous to pouring in the mixture, so that the portion next the vessel may not cool too suddenly and render the mixture less uniform in its consistence. Ceratum Calamine. Calamine Cerate. Turner's Cerate. Preparation.—Take of Yellow Wax three ounces, Lard one pound, melt them together, and when upon cooling they begin to thicken, add Prepared Calamine three ounces, and stir the mixture constantly until cool. Properties and Uses.—This cerate is mildly astringent, and may be used in excoriations and superficial ulcerations, produced by irritating secretions, chafing of the skin, burns, scalds, or other causes. Ceratum Cetacei. Spermaceti Cerate. Preparation.—Melt together White Wax three ounces, and Spermaceti one ounce; then add of Olive Oil, previously heated, six fluidounces, and stir the mixture until cool. Properties and Uses.—This cerate is employed as a mild dressing for blisters, wounds, and excoriations; and as the basis of more active preparations. Ceratum Crotonis. Croton Oil Cerate. Preparation.—Melt Lard five ounces, with White Wax one ounce, and when nearly cool, add Croton Oil two ounces, and stir until cool. Properties and Uses.—Croton oil cerate is a rubefacient and A-esicant, and may be used in all cases where such actions, or counter-irritation, are demanded. Ceratum Resinae. (Unguentum Resinae Albcc.) Resin Cerate. Ba- silicon Ointment. Preparation.—Melt together. Rosin five ounces, Lard eight ounces ; Yel- low Wax two ounces; then strain through linen to remove impurities which are apt to be present in the rosin, and stir the mixture constantly until cool. Properties and Uses.—This cerate forms a gently stimulant applica- tion to blistered surfaces, indolent ulcers, burns, scalds, and chilblains. Ceratum Sabin^e. Savine Cerate. Preparation.—Take of Savin, in powder, two ounces; Resin Cerate a pound. Mix together. Properties and Uses.—Savine Cerate is used as a dressing to perpetual blisters, in preference to the fly ointment, as it has no tendency to Cerei — Cereoli. 1029 produce strangury. It has a fine deep-green color, with the odor of the leaves, and as exposure impairs its properties, it should be kept in closely covered vessels. The Avhite coat which forms upon the blistered surface during the use of this cerate, should be occasionally removed, as it prevents its contact with the surface. Ceratum Simplex. Simple Cerate. Preparation.—Melt together, Lard eight ounces, White Wax four ounces; and stir constantly until cool. Properties and Uses.—Simple Cerate is a very mild application to irritated surfaces, and is used for dressing blisters, wounds, etc.; and also improperly employed as a vehicle for many substances to be applied by inunction. The lard employed in its preparation should be perfectly free from rancidity, and the heat should be as gentle as possible, so as not to produce the least decomposition. It should be put up in small jars, and closely covered with tin foil, in order to exclude the air. CEREI. CEREOLI. Bougies. Preparation.—Bougies are made by dipping strips of soft linen cloth, rather wider at one end than at the other, into certain emplastic or elas- tic compositions, folding them closely, and rolling them firmly on a smoo'h slab. For elastic bougies, pieces of catgut, bundles of thread, etc., are sometimes used. The following are some of the compositions held in most repute :—■ 1. Bell's.—Lead plaster four ounces; Yellow Wax owe ounce and a half; Olive Oil three drachms. 2. Hunter's.—Olive Oil three pounds ; Yellow Wax one pound; Red Lead one pound and a half; boil together over a slow fire till combined. 3. Savediaur's White. — White Wax one pound; Spermaceti three drachms ; Acetate of Lead from two drachms to one ounce; boil together slowly. 4. Piderit's Wax.—Yellow Wax six parts; Olive Oil one part. 5. Goulard's.—Yellow Wax six ounces; melted and mixed by stir- ring Avith Goulard's Extract of Lead from two drachms to two ounces. 6. Elastic—Boiled Linseed Oil twelve ounces; Amber four ounces; Oil of Turpentine four ounces, in which is dissolved Caoutchouc five drachms. Melt and Mix the articles well together, and spread the com- pound at three successive intervals upon a silk cord or web. Place the pieces, so coated, in a stove-oven heated to 150° F., and leave them in it for twelve hours adding fifteen or sixteen fresh layers in succession, until the instruments have acquired the proper size. Polish first with pumice-stone, and finally smooth with tripoli and oil. 1030 Pharmacy. Bougies are usually employed for dilating strictures, as of the urethra, vagina, neck of the uterus, and rectum. The largest size that can be conveniently introduced is first used, and the size gradually increased as the treatment progresses. The wax bougie is often employed for obtain- ing the form of an urethral stricture, its location and distance from the external orifice. CONFECTIONES. Confections or Conserves. Confectio Ros^e. Conserve of Roses. Confection of Roses. Preparation.—Rub Red Roses, in powder, four ounces, with Rose Water eight fluidounces, heated to 150°; then gradually add Refined Sugar, in powder, thirty ounces ; Clarified Honey six ounces. Beat the whole together in a marble mortar, until thoroughly mixed. An iron mortar will not answer. Properties and Uses.—This confection is slightly astringent, but is almost exclusively used as a vehicle of other medicines, or to impart consistence to the pilular mass. Confectio Sennae. Confection of Senna. Electuary of Senna. Leni- tive Electuary. Preparation. — Take of Senna eight ounces; Coriander [seed], four ounces; Liquorice Root, bruised, three ounces ; Figs a pound; Pulp of Prunes, Pulp of Tamarinds, Pulp of Purging Cassia each half a pound; Sugar [refined], two pounds and a half; Water four pints. Rub the senna and coriander together, and separate ten ounces of the powder with a sieve. Boil the residue with the figs and liquorice root, in the water, to one-half; then press out the liquor and strain it. Evaporate the strained liquor by means of a water-bath to a pint and a half; then add the sugar and form a syrup. Lastly, rub the pulps gradually with the syrup, and having thrown down the sifted powder, beat the whole together till they are thoroughly mixed.— U. S. History.—The confection of Senna, Avhen properly made, is an elegant preparation. The pulp of purging cassia is most conveniently obtained by boiling the bruised pods in water, straining the decoction, and evapor- ating to the consistence of an electuary. The pulp of prunes may be prepared by boiling the fruit in a small quantity of water to soften it, then pressing it through a hair sieve, and evaporating to a proper con- sistence. The tamarinds, when too dry for immediate use, may be treated in the same manner. In each case, the evaporation should be completed by means of a water-bath, in order to prevent the pulps from being burnt. Properties and Uses.—This is one of our best and most pleasant laxa- tives, being admirably adapted to cases of habitual costiveness, especially Decocta. 1031 in pregnant women and persons affected with piles. It is also very use- ful in the constipation which is apt to attend convalescence from fevers and other acute diseases. The mean dose is two drachms, to be taken at bed time.— U S. Disp. Off. Prep.—Confectio Sennae Composita. Confectio Sennae Composita. Compound Electuary of Senna. Pile Electuary. Preparation.—Take of Cream of Tartar and Pulverized Jalap of each one ounce; Confection of Senna two ounces; Flowers of Sulphur and Nitrate of Potassa, of each,half an ounce; Molasses, sufficient to make a thick pill mass. Properties and Uses.—Excellent for the blind and bleeding piles, and constipation. Half a drachm to a drachm may be taken every night dissolved in water; or it may be made into four-grain pills, of which four may be taken night and morning. DECOCTA. Decoctions. Decoctions are solutions of the medicinal virtues of various parts of plants, obtained by boiling these parts in water. The soluble principles of medicinal plants are generally more readily removed by water main- tained at the boiling point, than at a lower temperature; consequently decoction, in many instances, is preferred as a method of extracting the greatest degree of activity of the medicinal virtues of plants. The pro- cess of boiling should always be conducted in a vessel so covered as to confine the vapor over the surface of the liquid, and at the same time, prevent the access of atmospheric air, which frequently exerts an inju- rious influence upon the active principle; and as a general rule, the boiling should not be long continued, as the various principles existing in the plants may react upon each other, and impair their therapeutical influences. Vegetables, in which the active principle is volatile, in which ebullition would produce an unfavorable change so as to impair its activity, or in which it exists in combination with some inert or dis- agreeable principles not required, are not proper subjects for decoction, and in the latter instance, especially when the objectionable principles are to be obtained only at the boiling point. Decoctions should always be strained while hot. Dry substances, as roots, barks, woods etc., submitted to decoction, should be powdered, sliced, or bruised, according to their character, and the purest and safest water should be selected for use. Sometimes pre- vious maceration will be found beneficial by removing the cohesion of the vegetable fiber. In compound decoctions, where seAreral articles are to be boiled together, the various ingredients should be added at diffe- rent periods of the process, according to the length of time required to 1032 Pharmacy. extract their A'irtues; and should any of them possess a volatile active principle, it should be added at the last stage of the boiling to the hot decoction, which should be allowed to cool in a covered vessel. Tin or iron vessels are most commonly preferred in the preparation of decoctions; but iron utensils should never be used when astringent vegetables are employed. In some cases, glass or earthenware vessels are the best, as those made of metals are frequently corroded by the ingredients of the decoction. Decoctions are very seldom ordered from the apothecary, but almost always are made a matter of domestic management, hence, a list of decoctions is omitted as unnecessary, an explanation of the general rules relative to them being deemed sufficient. The ordinary mode of pre- paring decoctions, among Eclectics, is to alloAv one ounce of the article used to one pint of water, and the dose of which is from one to four fluidounces, depending on the activity of the agent, or the physiological effect which is required. Where the proportions are different from these, it wi 1 ] be referred to in the description of the properties and uses of the article. From various influences, decoctions are very liable to speedy change or decomposition ; consequently they should be prepared only when required for use, and should not be kept, especially in warm weather, for a longer period than forty-eight hours. EMPLASTRA. Plasters. Plasters are employed as external applications. They usually possess an amount of solidity requiring the aid of heat to spread them, and are adhesive at the usual temperature of the body. In the formation of plasters, the application of too much or too long- continued heat must be sedulously avoided, lest decomposition of one or more of the articles entering into their composition ensues, or perhaps some volatile principle, necessary to their activity, he driven off. After the ingredients composing them have been properly combined, it is usual to form them into cylindrical rolls or long square sticks, and cover them with paper, so as to exclude the air, the action of which is apt to change their color, and render them hard and brittle; when this condition takes place, it may, in a great degree, be remedied by melting the plaster with a moderate heat, and then a sufficient quantity of oil to impart to it the proper consistence. Plasters should be neither too soft nor too hard ; at ordinary temperatures they should be firm, should spread easily when moderately heated, and after being spread, should remain soft, pliable, and adhesive, without melting at the temperature of the body. Plasters are spread upon various articles according to the particular purposes they are intended to fulfill; when they are to be applied to the Emplastra. 1033 sound skin, leather is generally preferred ; and when used as a dressing to ulcerated or abraded surfaces, or for the purposes of approximating and retaining in contact the sides of wounds, either linen or muslin are employed. Sometimes oil-silk or India-rubber cloth is employed, and where economy is desired, they are spread on stout paper. The leather generally used for spreading plasters is white sheep-skin. After having cut the leather to the required shape and size, the plaster is spread thinly and evenly upon it, leaving a margin from a quarter of an inch to half an inch uncovered, in order to prevent the edges from soiling the clothing which may come in contact with it, as well as to facilitate its removal. This margin is accurately obtained by pasting strips of paper along the edges of the leather, of the desired width, leaving a space of the required dimensions in the center, and then removing them after the spreading has been effected. Or the same object mny frequently be accomplished by employing two narrow rules of sheet tin, graduated in inches, and so shaped that each of them may form two sides of a rec- tangle, being someAvhat similar in shape to a carpenter's square, but much smaller. These may be applied so as to inclose any given rectan- gular space, and may be fixed upon the leather while spreading the plaster by means of weights. When other shapes are required, as in the instance for plasters on the breast, or behind the ears, pieces of tin, having a vacuity within corresponding to the required outline, maj' be employed. A plaster may be spread by means of a common spatula, but the most convenient method is by means of a peculiar iron instru- ment made expressly for the purpose. This is heated by means of a spirit lamp, care being taken that its temperature be not so elevated as to discolor or decompose the plaster, or drive off any of its volatile ingredients. A sufficient quantity of the plaster should be first melted by the heated instrument, and received on a piece of coarse, stiff paper, and, when nearly cool, should be transferred to the leather, and applied evenly over its extended surface. This method prevents the melted plaster from penetrating the leather, which it is apt to do when applied too hot. When linen or muslin is employed, and the plaster is to be of large dimensions, it is recommended to pass the cloth "on which the plaster has been laid, through a. machine formed of a spatula fixed by screAvs at a proper distance from a plate of polished steel." When it is desired to obtain quantities of plasters, they are spread by a machine made for the purpose, for an account of which the reader is referred to " Pharmacy, by Mohr, Redwood and Procter." Plasters are used for the purposes of affording mechanical support or pressure to the parts to which they are applied; for binding up wounds; for preventing atmospheric contact, and as anodyne, discutient, stimu- lant, or epispastic applications. Emplastrum Belladonna. Plaster of Belladonna. 1034 Pharmacy. Preparation.—Take of Extract of Belladonna one ounce and a half; Resin Plaster three ounces ; place the plaster in an eartheinvare mortar, and put this in hot water. When the plaster commences to melt, add the Extract of Belladonna, and rub the ingredients well together. Then take the mortar from the water-bath, and continue the trituration till the mixture cools. Before the Belladonna is added to the plaster, it must first be brought into solution with water, so as to form a uniformly soft mass, and then Avhile the evaporation of the water is going on, the mix- ture must be constantly stirred ; without these precautions the extract cannot be made to diffuse uniformly through the plaster. Properties and Uses. — This forms a useful anodyne application in rheumatic, neuralgic and syphilitic pains; and if too long used is apt to produce the constitutional effects of the belladonna. Emplastrum Belladonnas Compositum. Compound Plaster of Bel- ladonna. Preparation.—Take of Resin Plaster five ounces; Extract of Bella- donna one ounce and a half; Extract of Conium Maculatum one ounce and a half; Pulverized Iodine two scruples. Place the plaster in an earthenware mortar, and put this in hot water. When the plaster com- mences to melt, add the Extracts of Belladonna and Conium, and rub the ingredients well together ; then take the mortar from the water- bath, continuing the trituration, and when nearly cool, add the Iodine. N. B. The inspissated juices of the above narcotics are preferable to the ordinary extracts in preparing this plaster. Properties and Uses.—This plaster may be used for the same pur- poses as the Belladonna Plaster, and is also an excellent application over scrofulous and other tumors, white-swelling, and goitre ; and may like- wise be applied over the region of the liver and spleen for chronic affec- tions of these organs, and over the lumbar vertebrae in severe dysmen- orrhea.—J. K. Emplastrum Capsici Compositum. Compound Capsicum Plaster. Common Strengthening Plaster. Sear Cloth Plaster. Preparation.—Take of Rosin one pound; Beeswax four ounces ; Cap- sicum four ounces ; Spirit one quart. Simmer the pepper, inclosed in a linen bag, in the spirit for one hour, then strain. Melt the other articles together, and add the tincture ; simmer till the spirit is nearly evapo- rated. Then take it from the fire, and when nearly cold, add Powdered Camphor two ounces ; Oil of Sassafras three drachms. Stir till cold. Properties and Uses.—This forms a gently stimulating and strength- ening plaster, and may be used in all cases where, artificial support, pre- vention of the contact of atmospheric air, or mild stimulation is required. Emplastrum Extracti Aconiti Radicis. Plaster of Extract of Aconite Root. Emplastra. 1035 Preparation.—Take of Aconite Root, in coarse powder, four ounces ; alcohol, sp. gr. 0.835, a sufficient quantity ; Adhesive Plaster three ounces and a half. Moisten the powdered Aconite root with six ounces of Alco- hol, and permit it to macerate twenty-four hours, then put it in a perco- lator, and when properly packed, pour on gradually sufficient Alcohol to make a pint of tincture. Distil off three-fourths of the Alcohol, evapo- rate the residue on a water-bath to a thick, syrupy consistence, then add the Plaster, previously liquefied, and stir constantly, until it is properly incorporated Avith the soft resinous extract, and cools. History.—This formula is recommended by Wm. Procter, Jr., as supe- rior to that in which only the aconitia enters, being more uniform in its strength and of equal efficacy. It has a brown color, and homogeneous consistence, and Aveighs about four Troy ounces. It should be spread in a thin layer on skin or oiled silk, and may be used several times when its application has not been too long continued at first. Properties and Uses.-—This extract is anodyne, and may be used as an application to painful and inflamed parts. It has been found decidedly beneficial in neuralgia of the head, and in painful tumors of the breast. Emplastrum Myrice. Bayberry Plaster. Green Salve. Preparation.—Take of White Gum Turpentine and Bayberry Wax, of each half a pound. Melt together, strain, and stir till cold. In winter a small quantity of Olive Oil may be added. Properties and Uses.—This forms a very valuable and efficacious appli- cation to scrofulous and other ulcers, also to many cutaneous affections. It is often prepared of the consistence of an ointment for these purposes. See Bayberry Ointment. Emplastrum Picis Compositum. Compound Tar Plaster. Irritating Plaster. Preparation.—Boil Tar three pounds, for half an hour ; then add Bur- gundy Pitch one pound and a half; White Gum Turpentine one pound, (having previously melted them together, and strained). Stir them together, remove from the fire, and add finely powdered Mandrake root, Blood root, Poke root, Indian Turnep, of each ten ounces. Incorporate well together. Properties and Uses.—This plaster is irritant, rubefacient and suppu- rative. It is used extensively in all cases where counter-irritation or poAverful revulsion is indicated, in neuralgia, rheumatism, and in all painful chronic diseases. It acts more efficiently, and is much more adhesive when spread quite thin, on soft leather, than when spread on any kind of cloth ; though it may be spread on oil-silk, india-rubber cloth, or other substance that will not absorb its moisture. When applied to a part of the body, it must be removed daily, for the purpose of thinly respreading the same leather with the plaster, which is to be immedi- ately reapplied. This course is to be continued until the surface to 1036 Pharmacy. which it is applied commences discharging matter, after which it should be removed tAvo or three times a day, wiping it quite dry each time before respreading it, and likewise carefully drying the sore as much as possible. This latter is best accomplished by laying a dry, soft cloth upon the sore, pressing it down lightly for a few minutes, so as to absorb all the pus or matter. The practitioner must bear in mind that he is never, under any circumstances whatever, to wet the sore, as it will cause it to become irritable and inflamed, to cease suppurating healthily, and in the majority of instances, to require rapid healing. Whenever the application of this plaster becomes so irritating and painful as to disturb the patient's sleep, or cause him to complain loudly, it must be removed, and a slippery elm poultice substituted ; otherwise, its longer employment will be apt 10 aggravate the local disease for which it is applied. Many practitioners consider the disturbance of sleep alone, as an indication for its removal. As soon as the elm poultice has relieved all the local irritation, the plaster may be reapplied, if it is required to maintain the suppurative discharge for a longer period of time. If this is not required, the sore may be healed by some simple application, as an ointment made of beeswax and mutton tallow, which is, probably, better than any other, as it does not stop the discharge too suddenly ; in some instances, the black-salve will be found an elegant healino- application. Whenever the plaster, poultice, or healing applica- tion is removed, the sore should, each and every time, be cleansed from matter, in the manner referred to above. The active principles of the inoredients entering into the composition of this plaster, are, undoubt- edly, absorbed into the system and exert an alterative influence, as their peculiar odors may be readily detected in the excretions. The Irritating Plaster is especially an Eclectic agent, not being used by the practition- ers of other schools.—T. V. M. Emplastrum Plumbi Oxidi Rubrum. Red Oxide of Lead Plaster. Black Salve. Preparation.—Take of Olive Oil three quarts; Rosin, Beeswax, of each three ounces. Melt together, and raise the mixture nearly to the boiling point ; then gradually add Pulverized Red Lead two pounds and a quarter. Stir constantly, and when the lead is taken up by the oil, the mixture becomes brown, or a shining black; then remove from the fire, and when nearly cold add of Pulverized Camphor half an ounce. It should remain on the fire till it forms a proper consistence for spreading, and which may be known by dipping a spatula or knife into it from time to time, and allowing it to cool. In the preparation of this plaster, it must be remembered that the oil will require a heat of about 600° for ebullition ; and should bubbles be observed when the heat is only 212°, it will probably be owing to the presence of water. If the oil, itself, is not brought to the boiling point, the red lead will not be acted upon; Emplastra. 1037 hence, the operator should not add it until the oil has been so far heated as to scorch a feather when dipped into it. Properties and Uses.—This is also another agent peculiar to Eclectic practice, and forms a valuable application in burns, many cutaneous affections, and in syphilitic, scrofulous, fistulous, and all other species of ulcers. A preparation similar to the above is employed by many practitioners in preference; it is made as follows : Boil two quarts of linseed oil until it will scorch a feather, then gradually add one pound of red lead in powder, when the red lead is taken up by the oil, and the mixture is black, remove from the fire, and when nearly cold add tAvo ounces of oil of turpentine, and stir until the mixture is cold. Emplastrum Plumbi. Lead Plaster. Litharge Plaster. Preparation.—Take of Semivitrified Oxide of Lead, in very fine pow- der, five pounds; Olive Oil a gallon; Water two pitds. Boil them together over a gentle fire, stirring constantly until the oil and oxide of lead unite in a plaster. It will be proper to add a little boiling Avater, if that employed at the commencement be nearly all consumed before the end of the process.— U. S. When the plaster is formed it should be removed from the fire, and after a short time cold water should be poured upon it; portions should then be detached from the mass, and, having been Avell kneaded under water, in order to separate the viscid liquid contained in the interior, should be formed into cylindrical rolls, and wrapped in paper. History.—In the preparation of this plaster, there ensues a reaction between the oil and water, which gives rise to a sweetish substance, glycerin, and to the development of oleic and margaric acids, and, when animal fat is substituted for the olive oil, to a third acid, tie stearic. The union of these acids with the oxide of lead, forms the plaster, Avhich is a true oleo-margarate of lead. The glycerin becomes mixed Avith the plaster, or remains dissolved in the water. According to recent chemi- cal views it is the oxide of glyceryle which exists in the oil, and which is developed with the fatty acids in the above process; this becomes gly- cerin by taking an equivalent of water. Glyceryle is a hypothetical compound of carbon and hydrogen, (&> H7 ) and forms oxide of glyce- ryle on uniting with five equivalents of oxygen, (C6 Ht 0 ), likewise a hypothetical compound, and with an additional equivalent of water it forms glycerin (Co H: 0; +H0). In preparing lead plaster it is very important that the oil employed be pure and free from rancidity, otherwise an imperfect product only will be obtained. A good plaster has been made by substituting- lard for the oil, in the proportion of eight pounds of lard to five of litharge. The only oily matters Avhich can be substituted for olive oil, are animal fats, and the only substitutes for the litharge are massicot, and minium, but 1038 Pharmacy. these require a much longer time to perfect the process, than when the officinal formula is followed. In making lead plaster first introduce the oil into a vessel capable of holding tAvice the quantity of oil used, and then by means of a fine sieve, sprinkle in the litharge, and constantly stir the mixture ; this course prevents the oxide of lead from cohering in small masses, and allows the oil to easily penetrate it, thus facilitating the process. The water not only exerts an important agency chemically considered, but prevents too high a temperature, which Avould decompose the oil, and reduce the oxide to the metallic state. It must, therefore, be supplied by fresh additions of boiling water, from time to time, as directed in the formula; cold Avater Avould not only delay the process, but might cause a dangerous explosion. The articles should be con- stantly stirred during the process of boiling, and care taken to prevent the oxide from sinking to the bottom of the vessel; and as soon as the articles have completed their union the boiling should cease. This may be known by the litharge gradually becoming paler, until, when the pro- cess is complete, the mixture is nearly Avhite. In the early part of the boiling the materials swell up considerably, OAving partly to the evapora- tion of the Avater, and partly to the escape of carbonic acid gas, which is set free by the action of the oily acids upon carbonate of lead which is generally contained in greater or less quantity in the litharge. The con- sistence of the mass increases Avith the boiling, and toAvard its termi- nation, or when the mass is sufficiently thick, a portion of it may be removed by means of a spatula, and cooled, when it will be found pos- sessed of sufficient firmness not to adhere to the fingers. When per- fected the plaster will present no red points of uncombined litharge ; and should these exist they must be broken down by trituration, and the boiling continued until they have all disappeared. Too much heat must not be employed in the operation, lest the plaster become burned. Properties and Uses.—This plaster is more commonly known by the name of Diachylon, and is chiefly used in the preparation of other plasters. It is likewise employed as an application to slight wounds, blistered and chafed surfaces, and occasionally to some ulcers, all of which it serves to protect from atmospheric influence. The sedative character of the lead entering into its formation, probably, assists its beneficial action. An ointment is in considerable use as a dressing for burns, scalds, chilblains, and various cutaneous affections accompanied with a burning or smarting sensation. It is prepared as follows : Take of Lead Plaster one pound and a half; melt it by a gentle heat, and when melted, add to it, Oil of Turpentine nine fluidounces ; Linseed Oil three fluidounces ; Oil of Origanum one pound; Tincture of Opium three fluidounces. Stir the articles constantly until the mass has sufficiently cooled. This is applied by completely and thickly covering the affected part with the ointment, over which a layer of raw cotton is to be placed, and allowed Emplastra. 1039 to remain until the part is well. In the case of deep burns, should the pain return after a few hours, the ointment should be removed, softening it Avith some warm oil, and a cataplasm of elm bark, or flaxseed, be applied. It is said to afford prompt relief. Emplastrum Resinae. Resin Plaster. Adhesive Plaster. Preparation. — Take of Rosin half a pound; Lead Plaster three pounds. Melt the Lead Plaster over a gentle fire, add the Rosin, and mix them.— U. S. History.—This preparation is the common adhesive plaster of the shops, and is usually spread upon muslin, by means of a machine made for the purpose. Long exposure to the air lessens its adhesiveness, in consequence of which the supply should be frequently renewed. Soap is sometimes added to the mixture, which increases its pliability without impairing its adhesiveness, beside lessening its liability to crack during cold weather. The following formula is stated to give an elegant plaster of this kind; take of Resin Plaster three ounces; Lead Plaster thirteen drachms and a half; Soap, sliced, two drachms and a half. Melt together and spread on linen. Properties and Uses.—This is more stimulating than the lead plaster, and also more adhesive. It is generally employed for retaining the sides of Avounds in contact, and likewise for dressing ulcers, drawing the edges toward each other, and giving a firm support to the granula- tions. The additions of turpentine or Burgundy pitch to it, are objection- able, as they increase its tendency to irritate, which should always be avoided as much as possible. An adhesive plaster is prepared by Pettenkofer, which contains no oxide of lead ; it is made by decomposing a solution of soap by means of a solution of chloride of calcium. The precipitate is expressed, dried, and powdered with half its weight of turpentine dried by heat; and the mixture is then melted along with an eighth part of suet, in boiling water. The boiling is continued, aintil the mass melts into a homogeneous fluid, when it is worked by the hand, in the ordinary manner, in cold water. Should portions of the above precipitate of calcareous soap not melt, they should be separated by straining through flannel. Emplastrum Resinae Compositum. Compound Resin Plaster. Ad- hesive and Strengthening Plaster. Preparation. — Take of White Rosin three pounds; Beeswax four ounces; Burgundy Pitch four ounces; Mutton Tallow four ounces. Melt these together, and add, Olive Oil, Pulverized Camphor, and Sassafras Oil, of each half an ounce; West India Rum four fluidounces. Incorporate well together, and then pour the whole into cold water, and Avork it in the hands till cold, forming it into rolls or sticks. 1040 Pharmacy. Dr. W. P. Watrous, of Mount Sterling. Ivy., prefers the following :— Melt together, Rosin three founds; Bees wax four ounces; take from the fire, and when nearly cold add, gradually, Camphor half an ounce, dissolved in Oil of Hemlock, Oil of Sassafras, and Olive Oil, of each one ounce, Oil of Turpentine half an ounce. Work in water as above. Properties and Uses.—This forms an adhesive and stren«-theninc plaster useful in rheumatism, weakness of the joints, Avounds, ulcers, etc. It is possessed of considerable stimulating property, and has been frequently used by Eclectic practitioners ; yet, notwithstanding it is an unscientific preparation, as the Rum and Tallow will not be found to unite readily. The Emplastrum Capsici Compos, is a much better article to use for the same purposes. The formula of Dr. Watrous, will be found a good one, forming an elegant plaster. ENEMATA. Injections or Clysters. Injections are liquid substances, sometimes containing powdered ingredients, and Avhich are intended to be thrown into the rectum either for the purpose of effecting a speedy evacuation from the bowels, for producing the impression of a particular agent upon the inferior portion of the alimentary canal and the adjacent tissues and organs, or for effecting an influence generally upon the system, through the medium of the surface, to Avhich they are applied. They are also thrown into the vagina to aid in restoring the normal condition of its walls, to remove vaginal leucorrhea, to aid in the cure of excoriation or ulceration of the cervix, etc. When thrown up the rectum, they are frequently employed to assist the action of remedies taken by the mouth, or to act as a substitute for them when the stomach rejects them, or is not susceptible to their influ- ence, and are also used when the rectum or its vicinity is the seat of disease. As a general rule, about double the quantity of an agent may be used as an injection per rectum, as Avould be required to produce an effect when taken into the stomach ; yet with regard to very aeuVe remedies, this rule should be acted upon with caution. Again, it must be borne in mind that the impression of an agent upon the stomach may be very much diminished by its frequent use, while the rectum will con- tinue to preserve its ordinary susceptibility to the action of such agent when used in enema. When an evacuation of the bowels is designed, the quantity of fluid administered by injection, should be very large ; thus, for an adult, a pint or even a quart, may be employed, and which in some instances, as in bilious colic, will require a repetition of this quantity in the course of ten or fifteen minutes ; for a child from nine to twelve years of age, * Enemata. 1041 half that quantity may be used; and for infants less than a year old, from one to three fluidounces. When the peculiar impression of the remedy upon the parts, or upon the system generally is intended, it should be given in as little quantity of fluid as is compatible with its activity or character, and should be retained within the rectum as long as possible. Any immediate desire to discharge the injected fluid, should in all cases be resisted by the patient; and it may frequently be required on the part of the nurse or physician to aid its retention, by making a moderately firm pressure upon the fundament, with a warm compress of linen or muslin. Injections are a very valuable mode of treatment in many diseases; indeed some affections cannot be readily nor permanently cured without them. They are found especially beneficial in bilious colic, in bilious, typhus, yellow, and congestive forms of fever, in dysentery and diarrhea, etc. In infants, life has often been preserved by their timely applica- tion; and the pains and dangers of the parturient woman, have frequently been very materially lessened by their use. And yet, notwithstanding their value and importance, there are hundreds of families, especially in country places, who do not supply themselves with the articles necessary for their administration, but who depend entirely upon the physician, or perhaps a neighbor, for the use of a syringe. This is a very repre- hensible omission, and although not exactly within the province of this work, yet, from the evil results which I have seen depending upon a negligence of the above character, I cannot refrain from making a few brief advisory remarks. Every individual, and more especially every family, is liable to sickness which may require the use of a syringe, and to depend upon the physician for its supply is certainly bad policy, for very few, especially among those practicing in the country, furnish themselves with a quantity sufficient to meet the demands of the various families under their professional care; beside, very few physicians carry an article of this kind, and in some diseases, the delay occasioned by sending for it, may be death to the patient. No doubt, an immense number of patients, and more particularly among those residing in the country, die yearly solely from the Avant of an instrument with which to administer an injection. It is therefore a matter of duty with the prac- titioner, both to himself and to his patients, to strongly impress these facts upon those who patronize him professionally, and urge them by all means to make the necessary provision. A metallic syringe capable of holding a pint, and a smaller one of three or four fluidounces, should be found in the possession of every family, as these can be adapted to meet any emergency requiring their use. Injections are emollient, stimulant, anodyne, purgative, antispasmodic, etc., and are most generally prescribed by the physician to suit the emergency of the case, without regard to officinal directions. For pur- poses of nutrition, as well as to reduce inflammation of the lower 66 1042 Pharmacy. intestines, infusions of starch, of elm bark, of flaxseed, and of corn meal, are usually injected into the rectum, Avith a portion of laudanum added when inflammation is present; and in cases where the stomach rejects all food and medicine, and when this condition is accompanied Avith prostration, a proper quantity of wine, brandy, or some similar stimu- lant may be added to the nutrient clyster, and repeated as often as the circumstances require. The following are among the agents of this class, in more common use. Enema Aloes Composita. Compound Clyster of Aloes. Preparation.—Take of Aloes two scruples ; Carbonate of Potassa fifteen grains; Tincture of Assafetida three fluidrachms; Infusion of Boneset half a pint. Mix, and rub them together.

It may be repeated two, three, or four times a day. It may likewise be used in ascarides, obstinate constipation, and amenorrhea. Enema Xanthoxyli. Clyster of Prickly Ash. Preparation.—Take of Water one fluidounce; Tincture of Prickly Ash Berries one fluidrachm; Tincture of Opium twenty minims; mix together. Properties and Uses.—This clyster will be found very beneficial in tympanitic distension of the abdomen from any cause. It will likewise be found efficacious in Asiatic cholera, and in diarrhea; in these last diseases it should be given and repeated immediately after each opera- tion from the boAvels, and should be retained in the rectum as long as possible. I have also used it with much benefit in the tympanitic abdomen of children, which so generally proves fatal, and which attends or follows an attack of diarrhea or summer complaint.—J. K. EXTRACTA. Extracts. Extracts, in medicine, are solid or semi-fluid substances obtained by evaporation of the decoction, infusion, tincture, or juice of vegetable principles. The object in preparing them is to obtain as large an amount of the active principles of a remedy, with as little of its inert constituents as possible. Sometimes it becomes necessary to separate these active principles from each other, especially when their influences upon the system vary considerably; and this is generally accomplished by means of a menstruum which dissolves the principle required, leaving the others untouched. Extracts vary very much in their composition, and which is OAving to the peculiar character of the remedies from which they are obtained, to the nature of the menstruum employed in dissolving their active principles, and to the process pursued for preparing them. The principles of plants most generally obtained by means of water, are gum, starch, sugar, tannin, extractive, coloring matter, various salts, together with certain principles peculiar to each plant; when alcohol is employed, resins, fatty matters, essential oil, and other principles not soluble in water are also obtained. And among these principles only such are selected as contain the active medicinal properties of the plant employed. The principles of plants are obtained either in a liquid state by expression of the plant, or by the agency of a proper solvent. When by expression, the plant must be fresh, cut into pieces, and bruised in EXTRACTA. 1045 a stone mortar or mill, till brought to a pulpy consistence; and if it be not very succulent, a little water must be added to dilute the juice. The pulp is then introduced into a linen or canvas bag, and the liquid expressed. After filtering, it should be evaporated by a very gentle heat to the proper consistence. Should the juice hold in solution starch, or other inert principles which may be removed by heat without injuring its medicinal properties, it may be heated to about 160° previous to filtration, which will precipitate the inert substances. Extracts thus prepared are sometimes called Inspissated Juices (Sued Spissati). When obtained by solution, dried vegetable agents are commonly used, though occasionally they require to be recent, and the menstruum employed is either water, alcohol, or a mixture of the two, depending on the solubility of the active principles in these fluids, ether, or acetic acid. Extracts obtained by the agency of water, are called Watery or Aqueous extracts; those by means of alcohol, Alcoholic extracts; those in which both Avater and alcohol are employed, Hydro-alcoholic extracts; and those obtained by means of ether, Ethereal extracts. Wine and acetic acid as solvents, yield vinous and acetic extracts. In the preparation for an extract, the operator should previously acquaint himself with the nature of the principles contained in the drug, their solubility, their relations to heat and air, their volatility, etc., so that he may adopt the men- struum best calculated to remove the greatest amount of active matter, and control the evaporation, so that this may not be injured by heat, nor lost by volatilization. In forming the solution for aqueous extracts, rain, river, or distilled water only should be used, and the vegetable should be thoroughly bruised, or reduced to the state of coarse powder; if too finely pulve- rized a precipitate of the inert or undissolved portions is apt to readily take place. Boiling water should then be poured on, and a gentle heat maintained for twenty or thirty minutes, according to the greater or less degree of solubility of the active principles, the vessel inclosing the arti- cles being covered. Successive portions of water must be employed until the whole of the active matter is extracted. Filter the solutions, and evaporate in a sand or Water-bath, until the proper consistence is attained. The evaporation should be conducted as quickly as the nature of the solution will admit, using a broad, shallow-dish, and toward the end of the process, it should be constantly stirred with a spatula. Long boilino-, and even the boiling temperature, causes the decomposition of many vegetable principles, or at least so modifies them as to render them inert; it is, therefore, recommended to substitute for decoction, the pro cess of maceration in Avhich the liquid acts without heat, which may be employed where the matter is readily soluble in cold Avater; that of digestion in which the action of the liquid upon the vegetable principles is assisted by a moderately increased temperature, sustained for a length of time ; or that of infusion, where the water is poured boiling hot upon 1046 Pharmacy. the plants, and allowed to stand for a short time in a covered vessel, and which is used where the virtues of the plant are not readily yielded to cold water. Long continued evaporation injures an extract more or less, hence it is always desirable to obtain the solution at first, as concen- trated as possible, in order to avoid this result. And in those instances where successive portions of water are used, those which are the least impregnated should be evaporated first, and brought to the strength of the stronger solution before mixing them, so that the latter may not be exposed to unnecessary heat. Alcoholic Extracts are made from tinctures of vegetables, the alcohol being either distilled off, or evaporated in the open air. Hydro-alcoholic Extracts should be prepared by exhausting the vegetable with each fluid separately, evaporate separately, and then combine the two extracts while hot. When the active principle of a plant is soluble in water, an Aqueous extract is commonly prepared ; when it depends upon a resin, oil, or other substance insoluble in water, an Alcoholic extract is pre- pared ; and a Hydro-alcoholic extract, when both of these liquids are required to take it up. And whatever mode may be employed in pre- paring the extract, occasional agitation or stirring, will always be re- quired. Ether is much employed in the preparation of extracts, and is espe- cially adapted to those articles whose medicinal properties are contained in a volatile oil or resin, or in both combined. An Ethereal tincture is first prepared by displacement, and the ether is then distilled off at a very moderate heat, or allowed to escape by spontaneous evaporation. Mr. W. S. Merrell has invented an instrument, by means of which as the percolated tincture falls into the receiver, the ether is driven off to pass again through the articles, and thus continue until all their strength is exhausted ; the whole process of tincturing and forming an extract being thus performed at the same time. These ethereal extracts are generally of a semifluid consistence. In the preparation of extracts, the employment of " Smith's Patent Vapor Displacement Apparatus," or an apparatus upon a similar prin- ciple, is decidedly the best that can be used, both for obtaining all the active principles of plants in solution, and for procuring extracts of supe- rior quality; and when largely manufactured, this apparatus cannot av ell be dispensed with. It is to the employment of an improved apparatus invented by himself, and embracing this principle, that the various syrups, extracts, etc., of our Pharmaceutist, William S. Merrell, owe their superiority to all others. Although Mr. Smith has patented this mode, yet we have understood that it was in operation many years ago, and is not a new discovery. In order to keep well, extracts should be placed in glass, stone, or porcelain jars, and completely prote :ed from the access of the air; and the application of alcohol to the surface, while it does not injure the extract, has a tendency to prevent moldiness. ExTRACTA. 1047 Extractum Aconiti Alcoholicum. Alcoholic Extract of Aconite. Preparation. — Take of Aconite Root, or recently dried Leaves, a pound; Diluted Alcohol four pints. Moisten the Aconite with half a •pint of the Diluted Alcohol, and, having allowed it to stand for tAventy- four hours, transfer it to an apparatus for displacement, and add gradu- ally the remainder of the Diluted Alcohol. When the last portion of this shall have penetrated the Aconite, pour in sufficient Water from time to time to keep the powder covered. Cease to filter when the liquid which passes begins to produce a precipitate, as it falls, in that which has already passed. Distil off the Alcohol from the filtered liquor, and evaporate the residue to the proper consistence.— U. S. History.—Care must be taken in the evaporation, that the heat be not greater than that produced by a vapor-bath, otherwise decomposition Avill be apt to ensue ; a water-bath is preferable on this account, to heat directly applied. The addition of water in the latter part of the displace- ment, is for the purpose of expelling the spirituous solution which has been absorbed by the Aconite; and as a precipitate ensues as soon as the water passes off, the filtration is directed to cease as soon as the pre- cipitate appears. When the process is properly performed, the extract procured is much better and more active than the inspissated juice; it is the only extract of this drug which should be used. Properties and Uses.—Extract of Aconite possesses the properties of the plant in a powerful degree ; it may be used in rheumatism, neuralgia, gout, scrofula, cutaneous diseases, inflammatory and febrile diseases, and in all cases in which the use of aconite is admissible. The dose is from half a grain to a grain, to be repeated two or three times a day, and gradually increased if necessary. The extract prepared as above, from the root, is said to be more ener- getic than that from the leaves, and is to be given in doses of one-sixth or one-quarter of a grain, two or three times a day, and gradually increased. Extractum Aletris Alcoholicum. Alcoholic Extract of Unicorn Root. Aletridin. Preparation.—Take of coarsely powdered Unicorn Root, two pounds ; Alcohol, ninety per cent., a sufficient quantity. Moisten the Unicorn root with two pints of Alcohol, and let it stand twenty-four hours ; then transfer it to a displacement apparatus, and gradually add Alcohol until it passes off without any taste of the root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the powder in the displacement apparatus, add gradually a suffi- cient quantity of Water, until the liquid passes but slightly impregnated with the properties of the Aletris. Heat the filtered liquid to the boiling point, strain, and evaporate by a gentle heat to the proper consistence. 1048 Pharmacy. Mix the alcoholic and aqueous extracts while each are hot, and stir con- stantly until cold. Properties and Uses.—This forms a very elegant and useful prepara- tion of Unicorn Root.

Heat the filtered liquid to the boil- ing point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses. — Hydro-alcoholic Extract of Blue Cohosh is antispasmodic and parturient. It may be advantageously combined with Extracta. 1051 dioscorein in bilious colic, flatulency, and griping pains arising from the use of drastic purgatives; with xanthoxylin, hydro-alcoholic extracts of cimicifuo-a, or Scutellaria, in rheumatic affections; and with senecin, cimicifugin, aletridin, asclepidin, or extract of cramp bark in uterine dis- eases. It will be found very useful in amenorrhea and dysmenorrhea; and forms with hydrastin an elegant remedy for deranged conditions of the stomach, dyspepsia, etc. It has also been found serviceable in after- pains. The dose is from one to five grains, three times a day.—J. K. Extractum Cimicifugae Hydro-alcoholicum. Hydro-alcoholic Ex- tract of Black Cohosh. Preparation.—Take of Black Cohosh Root, in moderately fine powder, two pounds; Alcohol a sufficient quantity. Moisten the Cohosh with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a dis- placement apparatus, and gradually add alcohol until it passes off without the taste of the root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the poAvder in the displacement apparatus add gradually a sufficient quantity of Water, until the liquid passes off but slightly impregnated with the properties of the Cohosh. Heat the filtered liquid to the boil- ing point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses.—Hydro-alcoholic Extract of Black Cohosh pos- sesses all the virtues of the root, and in nervous derangements, as chorea, epilepsy, etc., is much superior to the cimicifugin in action and efficacy; it is decidedly more narcotic and antispasmodic than this resi- noid. I make extensive and successful use of it in epilepsy, chorea, delirium tremens (in which I combine it with quinia), nervous excita^ bility, and many spasmodic affections. Persons subject to cramps will be speedily and permanently relieved by the employment of this extract combined with the extract of cramp bark. The hydro-alcoholic extract of black cohosh may be used in all instances where the employment of the root is indicated. The dose is from one to five or ten grains, three times a day.—/. K. Extractum Colocynthidis. Extract of Colocynth. Preparation.—Take of Colocynth, sliced and deprived of its seeds, three pounds; Diluted Alcohol half a gallon. Macerate the Colocynth in the Diluted Alcohol for thirty-six hours, occasionally pressing it with the hand. Express the liquor strongly and strain. Finally, evaporate to the proper consistence. Properties and Uses.—This extract is cathartic, and may be used in the dose of from five to thirty grains. Extractum Colocynthidis Compositum. Compound Extract of Colo- cynth. 1052 Pharmacy. Preparation.—Take of Colocynth, deprived of the seeds and sliced, six ounces; Aloes, in powder, twelve ounces; Scammony, in powder, four ounces; Cardamom, in powder, two ounces; Castile Soap three ounces; Diluted Alcohol a gallon. Macerate the Colocynth in the Diluted Alco- hol, with a gentle heat, for four days. Express and filter the liquor, and add to it the Aloes, Scammony and Soap; then evaporate to the proper consistence, and, near the end of the process, mix the Cardamom with the other ingredients. History.—Diluted Alcohol is a much better solvent of colocynth than water, hence it is directed in the above formula. The soap is added to improve the consistence of the extract, to render it more soluble in the fluids of the stomach, and to qualify the irritating action of the aloes and scammony. By exposing thin layers of this extract to dry air for a few days, it will be evaporated to dryness, in which state it may be powdered for admixture with other substances. Properties and Uses.—Compound Extract of Colocynth is an active cathartic, and may be employed in all cases where catharsis is indicated. From the difficulty with which pure scammony can be obtained in this country, I would suggest as a substitute for it, in the above formula, Podophyllin, in powder, two ounces, and which will by no means lessen the value or efficacy of the preparation. This extract may be especially used in obstinate constipation, and congestion of the liver or portal sys- tem. The dose is from five to thirty grains. Extractum Conii Alcoholicum. Alcoholic Extract of Poison Hem- lock. Preparation. — Take of the recently dried and coarsely powdered Leaves of Conium Maculatum half a pound; Diluted Alcohol four pints. Moisten the Leaves with half a pint of the Diluted Alcohol, and having allowed the mixture to stand for twenty-four hours, transfer it to a per- colator, and add gradually the remainder of the Diluted Alcohol. When the last portion of this shall have penetrated the powder, pour in suffi- cient water from time to time to keep the mass covered. Cease to filter when the liquid which passes begins to produce a precipitate, as it falls, in that which has already passed. Distil off the Alcohol from the filtered liquor, and evaporate the residue to the proper consistence. (See Alco- holic Extract of Aconite.) The heat in the preparation of this extract must be very moderate, or decomposition will ensue. Properties and Uses.—This extract is narcotic, and may be used in all cases where its peculiar influence is desired. The dose is from one- eighth of a grain, to one, two, or three grains, two or three times a day. Extractum Cornus Florida. Extract of Dogwood.

Properties and Uses.—The Extract of Bittersweet possesses the active properties of the plant, and may be beneficially employed in scrofula, syphilis, cutaneous diseases, and wherever the plant is indicated. The dose is from two to ten grains, three times a day. Extractum Eupatorii. Extract of Boneset. Preparation.—Take of the Tops and Leaves of Boneset a pound; Water a sufficient quantity. Mix the Boneset with a pint of the Water, and after allowing the mixture to stand for twenty-four hours, introduce it into a percolator, and pour Water upon it gradually until the liquid passes but slightly impregnated with the properties of the Boneset. Heat the filtered liquid to the boiling point, strain, and carefully evapo- rate to the proper consistence. Properties and Uses.—Extract of Boneset is tonic and aperient, and may be given with advantage in convalescence from exhausting diseases, intermittent fever, dyspepsia, debility of the digestive organs, and gene- ral debility. The dose is from one to ten grains, two or three times a day. Extractum Gentians. Extract of Gentian. Preparation.—Take of Gentian, in coarse powder, a pound; Water a sufficient quantity. Mix the Gentian with a pint of Water, and, after allowing the mixture to stand for twenty-four hours, introduce it into a displacement apparatus, and pour Water upon it gradually until the liquid passes but slightly impregnated with the properties of the Gentian. History.—Extract of Gentian is of a shining dark-brown color, nearly black, inodorous, very bitter, and tenacious. Properties and Uses. — This extract is a tonic, and may be used wherever this indication is present, either alone or in conjunction with other tonics. The dose is from one to ten grains. Extractum Gossypii. Extract of Cotton Bark. Extracta. 1055 Preparation.—Take of the inner Bark of the Root of the Cotton Plant, in coarse powder, a pound; Water a sufficient quantity. Mix the Bark with a pint of the Water, and after allowing the mixture to stand for twenty-four hours, introduce it into a displacement apparatus, and pour Water upon it gradually until the liquid passes but slightly impregnated with the properties of the Cotton Bark. Filter the liquid, and heat it to the boiling point, strain, and carefully evaporate to the proper con- sistence. Properties and Uses.—Extract of Cotton Bark is emmenagogue and abortivant. It will be found useful in amenorrhea and dysmenorrhea, combined with belladonna and quinia. The dose is from one to five or ten grains, three times a day.— J. K. Extractum H^ematoxyli. Extract of Logwood. Preparation.—Take of Logwood, rasped, a pound; Water a gallon. Boil down to four pints, and strain the liquor while hot; then evaporate to the proper consistence. History.—The evaporation of this extract should be carried to the extent of making it dry and brittle when cold. One hundred weight of logwood is said to yield about twenty pounds of extract. It is of a deep red color, and a sweetish astringent taste, and if made into pills and kept any length of time, it becomes so hard that the pills pass through the bowels unchanged. Properties and Uses.—Extract of Logwood is astringent and tonic, and will be found useful in diarrhea, dysentery, relaxed conditions of the bowels succeeding cholera infantum, and in chronic laryngitis or bron- chitis accompanied with considerable mucous expectoration. The dose is from five to thirty grains, two or three times a day. Extractum Helenii Hydro-alcoholicum. Hydro-alcoholic Extract of Elecampane. Preparation. — Take of coarsely powdered Elecampane Root two pounds; Alcohol a sufficient quantity. Moisten the Root with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a percolator, and gradually add Alcohol until it passes off without the taste of the root. Distil off the greater part of the Alcohol from this filtered tinc- ture, and evaporate the residue to the proper consistence. To the pow- der in the percolator, add gradually a sufficient quantity of Water, until the liquid passes but slightly impregnated with the properties of the Elecampane. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses.—This extract is stimulant and tonic, and is very useful in chronic pulmonary affections, debility of the digestive organs, 1056 Pharmacy. torpor of the liver, dyspepsia, and chronic cough. The dose is from one to ten grains, three times a day.— W. S. M. Extractum Hydrastis Hydro-alcoholicum. Hydro-alcoholic Ex- tract of Golden Seal. Preparation.—Take of the Root of Golden Seal, in powder, two pounds; Alcohol a sufficient quantity. Moisten the powdered Root with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a percolator, and gradually add Alcohol until it passes off without the taste of the Root. Distil off the greater part of the Alcohol from this filtered tinc- ture, and evaporate the residue to the proper consistence. To the powder in the percolator, add gradually a sufficient quantity of Water, until the liquid passes but slightly impregnated with the proper- ties of the Golden Seal. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses.—This extract possesses all the tonic virtues of the root, and may be used in all cases where that is indicated. In many instances it will be preferable to hydrastin, on account of the insolubility of the latter. The dose is from two to five grains, three times a day.—J. K. Extractum Hyoscyami Alcoholicum. Alcoholic Extract of Henbane. Preparation.—Take of recently dried Henbane Leaves, in coarse pow- der, a _/)own(/; Diluted Alcohol four pints. Moisten the Henbane with half a pint of the Diluted Alcohol, and, having allowed it to stand for twenty-four hours, transfer it to a percolator, and add gradually the remainder of the Diluted Alcohol. When the last portion of this shall have penetrated the Henbane, pour in sufficient water from time to time to keep the powder covered. Cease to filter when the liquid which passes begins to produce a precipitate, as it falls, in that which has already passed. Distil off the Alcohol from the filtered liquor, and evap- orate the residue to the proper consistence. The heat in the evapora- tion should not be greater than that produced by a vapor-bath, otherwise decomposition will be apt to ensue. (See Alcoholic Extract of Aconite.) Properties and Uses,—This extract contains all the medicinal virtues of the Henbane, and may be administered Avhenever this drug is indi- cated. The dose is from one-fourth of a grain, to two or three grains, three times a day. The smallest dose must first be given, and the quantity gradually increased until the desired influence is obtained. Extractum Iridis Hydro-alcoholicum. Hydro-alcoholic Extract of Blue Flag. Preparation.—Take of the coarsely powdered Root of Iris Versicolor two pounds; Alcohol a sufficient quantity. Moisten the Blue Flag with Extra cta. 1057 two pints of Alcohol, let it stand twenty-four hours, then transfer it to a disphicement apparatus, and gradually add Alcohol until it passes off without the taste of the Root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper con- sistence. To the powder in the displacement apparatus, add gradually sufficient Water until the liquid passes but slightly impregnated with the properties of the Blue Flag. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses.—The Hydro-alcoholic Extract of Blue Flag is a valuable cathartic and alterative. In doses of from one to five grains or more, it will be found a useful purgative in cases of obstinate consti- pation, hepatic torpor, indigestion, amenorrhea, etc. In larger doses it will produce hydragogue results, and may be given with advantage in chronic pulmonary affections, dropsy, worms, etc. In doses, to fall short of catharsis, it becomes a valuable alterative, and will be found especially useful in rheumatic diseases, scrofula, syphilis, etc., and will frequently cause ptyalism. A few grains of ginger or capsicum will prevent any harshness of action. As an alterative, the dose is from one- fourth of a grain to one grain, three times a day.—J. K. Extractum sive Resina Jalapae. Extract or Resin of Jalap. Preparation.—Take of Jalap, in moderately fine powder, two pounds ; mix it thoroughly with a sufficient quantity of Rectified Spirit to moisten it well, let it stand twenty-four hours, and then transfer it to a percola- tor, and gradually add Rectified Spirits until it passes off without any of the taste of the Jalap. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue OATer a vapor-bath, to the proper consistence. History.—This resin is dark-colored, brittle and of a shining fracture; and is sufficiently pure for practical purposes. The pure resin of jalap is white as flour, and is an active cathartic in doses of from three; to five grains. Jalap resin may, according to G. A. Kaiser, be known from all other resins by its gradual solution in concentrated sulphuric acid, and subsequent deposition of a brown, soft, viscid matter, on standing for a few hours. Guaiacum resin is frequently added to it; this fraud may be detected by making an alcoholic solution of the suspected resin, and adding to it a few drops of chloride of soda, or of lime; if guaiac be present, it produces a green color. Properties and Uses.—The purgative principle of Jalap depends entirely on its resin, and its diuretic properties on its gummy extractive. The resin prepared as above is an active cathartic in the doses of from 67 1058 Pharmacy. four to ten grains, with much pain and griping, but which may be obvi- ated by trituration with Castile soap, caulophyllin, or loaf sugar. Extractum Juglandis. Extract of Butternut. Preparation.—Take of the Inner Bark of the Root of Juglans Cinerea a pound; Diluted Alcohol a sufficient quantity. Mix the Bark with a pint of the Diluted Alcohol, and after allowing the mixture to stand for tAventy-four hours, introduce it into a displacement apparatus, and pour diluted Alcohol upon it gradually until the liquid passes but slightly im- pregnated with the properties of the Butternut. Heat the filtered liquid to the boiling point, strain, and carefully evaporate to the proper con- sistence. History.—Extract of Butternut is of a black color, sweetish odor, and bitter, astringent taste. The extract prepared by the country people is of an inferior kind, and should never be purchased by the apothecary. It is usually made Avith water, which does not extract all the medicinal virtue of the bark, and is likeAvise apt to be more or less injured by the improper application of heat. Hence, many practitioners, having used the country prepared extract, and found it uncertain in its effects, decry all other extracts. In preparing the extract, the bark of the root should be collected in May or June, and used while fresh. Properties and Uses.—A mild cathartic, acting upon the bowels Avith- out disposing them to subsequent constipation. The dose is from ten to thirty grains. Extractum Krameri^e. Extract of Rhatany. Preparation.— Take of the Bark of Rhatany Root, in moderately fine powder, a pound; Water a sufficient quantity. Mix the Bark of the Root with a pint of the Water, and after allowing the mixture to stand for twenty-four hours, introduce it into a displacement apparatus, and pour Water upon it gradually until the liquid passes but slightly impregnated with the properties of the Rhatany. Rapidly evaporate the filtered liquid to such a consistence, that Avhen cold the extract may be dry. History.—Good Extract of Rhatany is of a reddish-brown color, with a smooth, shining fracture, very astringent taste, and is almost completely soluble in water. In the above formula for preparing this extract, the evaporation should be conducted rapidly, or in a vacuum, because, when the infusion is exposed for a length of time to the action of the air, there is an absorption of oxygen, and the production of insoluble apotheme. The extract made by alcohol, or by decoction, is inferior to that made by the above process; the former containing from twenty to thirty per cent, less of the active principle than the officinal, and the latter containing nearly fifty per cent, of insoluble matter. By the for- mula given, the wood of the root yields 6.8 per cent, of extract, and the bark 33 per cent. Much of the Extract of Rhatany found in,the shops is of an inferior quality. ExTRACTA. 1059 Properties and Uses.—Extract of Rhatany may be used whenever an astringent is required ; in some cases it will be found preferable to any other agent of this class. The soft extract may be advantageously used as a local application to ulcers, hemorrhoids, and fissures of the anus. The dose is from five to twenty grains, three or four times a day. Extractum Leonuri Hydro-alcoholicum. Hydro-alcoholic Extract of Motherwort. Preparation.—Take of the recently dried herb Leonurus Cardiaca, in coarse powder, two pounds; Alcohol a sufficient quantity. Moisten the Motherwort with tAvo pints of Alcohol, let it stand twenty-four hours, then transfer it to a percolator, and gradually add Alcohol until it passes off without the taste of the herb. Distil off the greater part of the Alco- hol from this filtered tincture, and evaporate the residue to the proper consistence, by means of a very moderate heat. To the poAvder in the displacement apparatus, add gradually a. suffi- cient quantity of Water, until the liquid passes but slightly impregnated with the properties of the Motherwort. Heat the filtered liquid to nearly the boiling point, strain, and carefully evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses.—Extract of Motherwort is emmenagogue, ner- vine, and antispasmodic, and may be used with advantage in all forms of disease in which the cold infusion of the herb is recommended. The dose is from three to six grains, every two or four hours. It may be advantageously combined with asclepidin, or the hydro-alcoholic extracts of black cohosh, nerve-root, cramp-bark, scullcap, etc.— W. S. M. Extractum Leptandra Hydro-alcoholicum. Hydro-alcoholic Ex- tract of Blackroot. Preparation.—Take of the recently dried root of Leptandra Virginica, in coarse powder, two pounds; Alcohol a sufficient quantity. Moisten the Blackroot with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a displacement apparatus, and gradually add Alcohol until it passes oft" Avithout the taste of the root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the powder in the percolator, add gradually a sufficient quantity of Water, until the liquid passes but slightly impregnated Avith the pro- perties of the Blackroot. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses.—This extract possesses all the medicinal proper- ties of the Blackroot, and may be used wherever that is indicated. The 1060 Pharmacy. dose is from one to ten grains. It may be beneficially combined with the hydro-alcoholic extract of Wild Indigo, in typhoid diseases, and where an action upon the liver is desired without active catharsis. Extractum Lupulin^e. Extract of Lupulin. Preparation. — Take of Commercial Lupulin four ounces; Alcohol eight fluidounces. Place the Lupulin loosely in a percolator, cover with Alcohol, and allow it to stand an hour. Then gradually add Alcohol until two pints of filtered liquor are obtained. Pour this liquor in a shallow dish and set aside to evaporate spontaneously. History.—Commercial lupulin is more or less mixed with hops, and consequently varies in its activity. The above extract contains the me- dicinal principles of the hops unimpaired, is of uniform strength, and is in a form convenient for pills. In making larger quantities of extract, it would be economical to distil off about three-fourths of the alcohol, previous to spontaneous evaporation. Commercial lupulin yields about two scruples of extract to a drachm of the grains. Properties and Uses.—This extract possesses the active properties of the hops in an eminent degree, and may be used in all cases where lupulin is admissible. The dose is from two to ten grains three times a day. Extractum Mitchells. Extract of Partridge Berry. Preparation.—Take of the recently dried herb Mitchella Repens, in coarse powder, a pound; Water a sufficient quantity. Mix the herb with ajpint of the Water, and after allowing the mixture to stand for twenty- four hours, introduce it into a displacement apparatus, and pour Water upon it gradually until the liquid passes but slightly impregnated with the properties of the plant. Heat the filtered liquid to the boiling point, strain, and carefully evaporate to the proper consistence. Properties and Uses.—This extract is an invaluable preparation, and possesses the active medicinal virtues of the plant. It is employed more especially on account of its tonic influence upon the uterus; and in diseases of this organ, it may be usefully combined with cimicifugin, caulophyllin, aletridin, senecin, etc. The dose is from one to ten grains three times a day.—J. K. Extractum Nucis Vomice Alcoholicum. Alcoholic Extract of Nux Vomica. Preparation.— Take of Nux Vomica a pound; Alcohol a sufficient quantity. Expose the Nux Vomica to steam till it is softened ; then having sliced and dried it, grind it into poAvder. Introduce it into a displacement apparatus, and pour Alcohol upon it gradually, until the liquid passes without bitterness. Distil off the greater part of the Alcohol from the filtered liquor, and evaporate the residue to the proper consistence. Extracta. 1061 Properties and Uses.—This is an active preparation of nux vomica, but owing to the variable proportion of strychnia in the seeds, it is not always of uniform strength. It may be employed in cases where the action of this agent is required. It is very useful in cases of obstinate constipa- tion, and may be employed in the following combination : Take Extract of Butternut two grains ; Podophyllin one sixteenth of a grain; and Al- coholic Extract of Nux Vomica one-fourth of a grain; mix thoroughly together and form a pill, which is a dose, and may be repeated tAvo or three times daily, or until the desired effect is produced. The dose of the above extract of nux vomica is from one-fourth of a grain to two grains, repeated two or three times a day. Extractum Phytolacca Alcoholicum. Alcoholic Extract of Poke. Preparation. — Take of the recently dried Leaves of Poke, in coarse powder, a pound; Diluted Alcohol four pints. Moisten the leaves with half a pint of the Diluted Alcohol, and having alloAved it to stand for twen- ty-four hours, transfer it to a displacement apparatus, and add gradually the remainder of the Diluted Alcohol. When the last portion of this shall have penetrated the Poke, pour in sufficient Avater from time to time to keep the powder covered. Cease to filter when the liquid which passes begins to produce a precipitate, as it falls, in that which has already passed. Distil off the Alcohol from the filtered liquor, and evaporate the residue to the proper consistence, by means of a gentle heat. (See Alcoholic Extract of Aconite.) History —Extract of Poke prepared in this manner, is superior to that prepared in the ordinary way with water. The leaves employed in the preparation of the extract should be gathered immediately previous to the ripening of the berries, at Avhich period they are the most active. An extract may be prepared from the Poke-root in the same manner, but it is somewhat doubtful whether it is as energetic as that from the leaves. An extract formed by evaporating the expressed juice of the recent ripe berries is frequently employed, but it is presumed to be inferior in point of efficacy to that from the leaves. Properties and Uses.—These various extracts of Poke, are emetic and purgative in large doses; in medicinal doses they are alterative and are especially useful in syphilitic, mercurio-syphilitic, and rheumatic dis- eases, and particularly in the osteocopic pains of mercurio-syphilis. They lose their virtues by age, and should be freshly prepared every year. The dose is from one to five grains, or more, three times a day. The inspissated juice of Poke-berries, (Succus Inspissatus Phytolaccae, Baccce.) is frequently employed as a valuable agent in rheumatism ; it is milder than the extract prepared from the root, or leaves. Extractum Plantaginis Cordate Hydro-alcoholicum. Hydro-alco- holic Extract of Water Plantain. Preparation.—Take of the recently dried Root of Water Plantain, in coarse powder, two pounds; Alcohol a sufficient quantity. Moisten the 9- 1062 Pharmacy. Root with tAvo pints of Alcohol, let it stand twenty-four hours, then trans- fer it to a displacement apparatus, and gradually add Alcohol until it passes off without the taste of the root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the powder in the percolator, add gradually a sufficient quantity of Water, until the liquid passes but slightly impreg- nated with the properties of the Water Plantain root. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly until cold. Properties and Uses.—Hydro-alcoholic Extract of Water Plantain is astringent, and has been used with much success in Asiatic cholera, diarrhea, and dysentery. The dose is from one to ten grains, repeated every one, tAvo, or three hours, as the urgency of the case requires.— W. S. M. Extractum Polygoni. Extract of Water Pepper. Preparation.—Take of the recently dried herb of Water Pepper, in coarse poAvder, a pound; Water a sufficient quantity. Mix the herb with a pint of the Water, and after allowing the mixture to stand for twenty- four hours, introduce it into a percolator, and pour Water upon it gradu- ally until the liquid passes but slightly impregnated with the properties, of the Water Pepper. Heat the filtered liquid to the boiling point, strain, and carefully evaporate to the proper consistence. Properties and Uses.—Extract of Water Pepper is stimulant, diuretic, and emmenagogue, and is especially useful in amenorrhea, and chronic affections of the kidneys. The dose is from two to ten grains, three or four times a day. Extractum Pteleae Hydro-alcoholicum. Hydro-alcoholic Extract of Shrubby Trefoil. Preparation.—Take of the recently dried Bark of the Root of Ptelea Trifoliata, in coarse powder, two pounds; Alcohol a sufficient quantity. Moisten the Bark with two pints of Alcohol, let it stand for twenty-four hours, then transfer it to a percolator, and gradually add Alcohol until it passes off without the taste of the bark. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the powder in the percolator, add gradually a sufficient quantity of WTater until the liquid passes but slightly impregnated with the properties of the Ptelea. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly until cold. Properties and Uses.—This extract is an elegant preparation, and may be used in all cases where the Ptelea is indicated. Its use is at the ExTRACTA. 1063 present time superseded by that of the Ptelein. The dose is from two to ten grains. — W. S. M. Extractum Rhei. Extract of Rhubarb. Preparation.—Take of Rhubarb, in coarse powder, a pound; Diluted Alcohol a sufficient quantity. Mix the Rhubarb with an equal quantity of coarse sand, moisten it thoroughly with Diluted Alcohol, and allow it to stand for twenty-four hours ; then transfer it to a displacement appa- ratus, and add Diluted Alcohol gradually until four pints of filtered liquor are obtained. Evaporate this to the proper consistence by means of a water-bath.— U. S. History.—As the purgative principle of rhubarb is injured to a greater or less extent by heat, the above process must be performed with much care, employing only a moderate degree of heat. W'hen the drug is boiled in Avater, the tannin and starch, which form a part of its composi- tion, combine and give rise to a compound insoluble in cold water, and which, probably carries with it a portion of the purgative principle. It is supposed, also, that this principle is volatilizable by heat, and that a portion of it escapes with the vapor. Properties and Uses.—Extract of Rhubarb possesses virtues similar to the drug itself, and has the advantage of smallness of dose, and its capa- bility of being given in solution. The dose is from ten to thirty grains. Extractum Rumecis Hydro-alcoholicum. Hydro-alcoholic Extract of Yellow Dock. Preparation. — Take of coarsely powdered YelloAv Dock Root two pounds; Alcohol a sufficient quantity. Moisten the Yellow Dock Root with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a displacement apparatus, and gradually add Alcohol until it passes off without the taste of the root.

To the powder in the percolator, add gradually a sufficient quantity of Water until the liquid passes but slightly impregnated with the proper- ties of the Yellow Dock. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly until cold. Properties and Uses.—This extract is tonic and alterative, and is effica- cious in scrofula, and cutaneous diseases. It is most generally given in combination Avith some other alteratiA-e, as extract of Poke, Cimicifuga, Dulcamara, Corydallis, etc. The dose is from one to five grains, three times a day.— W. S. M. Extractum Sanguinariae Hydro-alcoholicum. Hydro-alcoholic Ex- tract of Bloodroot. Preparation. — Take of coarsely powdered Bloodroot two pounds; 1064 Pharmacy. Alcohol a sufficient quantity. Moisten the Bloodroot with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a displacement apparatus, and gradually add Alcohol until it passes off without the taste of the root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the powder in the displacement apparatus, add gradually a sufficient quantity of Water, until the liquid passes but slightly impregnated with the pro- perties of the Cohosh; then evaporate the filtered liquid to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot and stir constantly. Properties and Uses.—This preparation of Bloodroot is expectorant, alterative, and emmenagogue, and may be used with benefit in pulmo- nary and hepatic diseases, jaundice, and amenorrhea. Externally, it forms a mild caustic, and may be advantageously applied to indolent ulcers and fistula-in-ano. It possesses the virtues of the root. The dose is from one-eighth of a grain to a grain.—J. K. Extractum Scutellariae Hydro-alcoholicum. Hydro-alcoholic Ex- tract of Scullcap. Preparation. — Take of the recently dried Herb, Scullcap, in coarse powder, two pounds ; Alcohol a sufficient quantity. Moisten the Scullcap with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a displacement apparatus, and gradually add Alcohol until it passes off Avithout the taste of the root. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper con- sistence. To the powder in the displacement apparatus, add gradually a sufficient quantity of Water, until the liquid passes but slightly impregnated with the properties of the Scullcap. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly until cold. Properties and Uses.—The Hydro-alcoholic Extract of Scullcap is tonic, nervine, and antispasmodic. It has been used with advantage in cases of nervous excitability, chorea, wakefulness, and restlessness ; it may be used alone or in combination with the hydro-alcoholic extracts of cimicifuga, cypripedium, or asclepias The dose is from one to five grains, three or four times a day.— W. S. M. Extractum Stillingle Hydro-alcoholicum. Hydro-alcoholic Ex- tract of (Queen's Root. Preparation.—Take of the recent Root of Stillingia, cut into small pieces, two pounds ; Alcohol a sufficient quantity. Moisten the Stillingia with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a displacement apparatus, and gradually add Alcohol until it passes Extract a. 1065 off without the taste of the Root. Distil off the greater part of the Alco- hol from this filtered tincture, and evaporate the residue to the proper consistence. To the root in the percolator, add gradually a sufficient quantity of Water, until the liquid passes but slightly impregnated Avith the properties of the Stillingia. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses. — In large doses the Hydro-alcoholic Extract of Stillingia is emetic and cathartic, for which actions it is but little em- ployed in medicine, on account of the nausea, prostration, and burning sensation at the stomach caused by it. In small doses it is a valuable alterative, peculiar to Eclectic practice, and may be efficaciously used in all diseases requiring alterative remedies. It is usually given in combi- nation Avith other alteratives, the virtues of which it appears to increase. The Compound Syrup of Stillingia is now more generally used in prac- tice, but this extract will be found useful in cases where pills are pre- ferred to fluid preparations. The dose is one, two, or three grains, three times a day.— W. S. M. Extractum Stramonii Alcoholicum. Alcoholic Extract of Stramonium. Preparation.—Take of recently dried Leaves of Stramonium a pound; Diluted Alcohol four pints. Moisten the leaves with half a pint of the Diluted Alcohol, and, having allowed it to stand for twenty-four hours, transfer it to a percolator, and add gradually the remainder of the Diluted Alcohol. When the last portion shall have pentrated the Stra- monium, pour in sufficient water from time to time to keep the powder covered. Cease to filter when the liquid which passes begins to produce a precipitate, as it falls, in that which has already passed. Distil off the Alcohol from the filtered liquor, and evaporate the residue to the proper consistence. The heat in the evaporation should not be greater than that produced by a vapor-bath, othenvise decomposition will be apt to ensue. (See Alcoholic Extract of Aconite.) An Alcoholic Extract may be also made by substituting the Stramo- nium Seed, ground into poAvder, for the Leaves. The seeds are sup- posed to furnish a more energetic preparation. Properties and Uses.—The Alcoholic Extract of Stramonium is pre- ferrable either to an aqueous extract of the leaves, or their inspissated juice. It is, in large doses, a narcotic poison; in medicinal doses it is anodvne and antispasmodic, and may be administered with benefit in painful and periodic diseases, nervous excitability or irritability, gastritis, enteritis, peritonitis, dysmenorrhea, rigidity of the os uteri, etc., etc. It may also be applied externally in rheumatic and neuralgic pains, and to reduce local inflammations. The dose is from an eighth of a grain to a grain, three times a day. 1066 Pharmacy. Extractum Taraxaci. Extract of Dandelion. Preparation.—Take of the recent Root of Dandelion, gathered in Sep- tember, five pounds. Cut the root into small slices, and place it in a stone mortar; sprinkle on it a little water, and bruise it, until it is reduced to a pulp; then express the juice, strain, and evaporate in a vacuum, or in a shalloAv dish over a water-bath, constantly stirring, until it is of the proper consistence. History.—In the evaporation of this extract, too much heat or too long an exposure to the action of the air, causes the extract to lose part of its bitterness and become sweetish, which is a sign of inferiority. To be good, the extract must be bitter and entirely free from any sweetness. The roots furnish a thirl, watery, feeble-flavored juice Avhen collected in the spring; while those gathered in autumn yield a thick, cream-colored, and bitter juice, amounting frequently to one-half the Aveight of the root. Age deteriorates this extract, hence, it should be freshly made annually. Properties and Uses. — Extract of Dandelion is tonic, diuretic, and aperient. It is much recommended in affections of the liver, spleen, and kidneys, in dropsical diseases, etc. I have made much use of vari- ous preparations of dandelion, and the effects are far from being so decided and beneficial as the testimony of writers led me to suppose; we have several agents vastly superior to it in medicinal efficacy, in the diseases for which it is prescribed. The dose of it is from ten to sixty grains three times a day. Extractum Viburni Hydro-alcoholicum. Hydro-alcoholic Extract of High Cranberry Bark. Hydro-alcoholic Extract of Cramp Bark. Preparation.—Take of coarsely powdered Bark of Viburnum Opulus two pounds; Alcohol a sufficient quantity. Moisten the Bark with two pints of Alcohol, let it stand twenty-four hours, then transfer it to a dis- placement apparatus, and gradually add Alcohol until it passes off with- out the taste of the High Cranberry Bark. Distil off the greater part of the Alcohol from this filtered tincture, and evaporate the residue to the proper consistence. To the powder in the displacement apparatus, add gradually a suffi- cient quantity of Water, until the liquid passes but slightly impregnated with the properties of the High Cranberry Bark. Heat the filtered liquid to the boiling point, strain, and evaporate to the proper consistence. Mix the alcoholic and aqueous extracts while each are hot, and stir constantly till cold. Properties and Uses. — Hydro-alcoholic Extract of High Cranberry bark is tonic and antispasmodic, and may be used in all cases in which the High Cranberry bark is indicated. In uterine difficulties it may be advantageously combined with some uterine tonic, as cimicifugin, aletri- din, senecin, caulophyllin, etc. In bilious and flatulent colic, and spas- EXTRACTA FLUIDA. 1C67 modic pains of the stomach and bowels, it will be found very efficacious in combination with dioscorein. The dose of it is from one to ten grains, three times a day.—J. K. EXTRACTA FLUIDA. Fluid Extracts. These are concentrated medicinal principles, not reduced to a solid or nearly semifluid consistence as with extracts, and have the advantao-e over ordinary extracts in being prepared with less evaporation, and con- sequently less heat, whereby their activity is not so liable to impairment. With some medicines, as for instance, Cubebs, in which the medicinal virtue depends entirely upon a fluid substance, and cannot be reduced to a solid extract, the Fluid Extract presents a valuable mode of administra- tion. The menstruum employed in the preparation of fluid extracts varies according to the character of the constituents comprising the vir- tues of the plant; thus, many agents require only Water, and those containing oil and resin require Alcohol or Ether, according to the deo-ree of solubility in these menstrua, and their action upon non-medicinal principles which may exist in the substance under operation. One great difficulty relative to fluid extracts is their liability to spontaneous decomposition; this may be counteracted to a great extent by the addi- tion of loaf-sugar, in the proportion of one ounce to every fluidounce of the extract; or other preservative agents may be employed in some cases, as alcohol, etc. When prepared by means of ether, these extracts generally keep well and for a long time, without any material unfavor- able change. Fluid Extracts. by w. s. merrell. In our article on the " Progress of Pharmacy," it was obseived that the Fluid Extract was a neAv and very eligible form, in the present state of the science, of exhibiting many valuable remedies. The medical powers of vegetables, as has been stated, depend on certain proximate principles, as acids, essential oils, resinoids, alkaloids, etc., and to obtain these in their separate and pure state, constitutes the climax of phar- maceutical progress; but there are many valuable plants of which the requisite analysis has not been made; others, in which the principle in which the chief medical activity resides is combined with some native acid, or with other principles of an extractive or mucilaginous character, which modifies their pathogenetic action; and in other cases again, we wish to obtain, in combination, the medical properties of several articles, of which the proximate principles are diverse, and to obtain them pure would require separate and dissimilar processes. Now, as nearly all medical principles are soluble in alcohol, either pure or dilute, all these 1068 Pharmacy. properties of an article or a compound, may be extracted by this men- struum, and presented together in their native state and proportions; and althouo-h such extracts are not as concentrated nor as definite in their strength as the pure proximate principles, yet, if skillfully pre- pared, they are sufficiently so for use in most cases. The strength and quantity of Alcohol may properly be varied, as the ingredients are more or less resinous in their character. But the follow- ing formula will be found sufficiently definite in most cases: R- Ingredients to be extracted,...........one pound. Alcohol, 76 per cent.,................four pints. White Sugar,.......................four ounces. Water.............................a sufficient quantity. Add to the ingredients, in a convenient close vessel, enough Alcohol to thoroughly wet them, and digest with as much warmth as can be used without distilling off the Spirit for twenty-four hours. Then transfer the whole to a percolator or displacement apparatus, and gradually add the rest of the Alcohol, returning a little of the first that comes through, till it runs clear. Reserve, by itself, of the first or strongest running, four fluidounces ; evaporate the remaining Alcoholic Tincture that comes through to four fluidounces, and likeAvise set it aside. Then pour hot water on the residuum in the percolator, until the liquid that comes through has very little of the color or taste of the medicine; evaporate this latter solution to half a pint, then add the Sugar, continue the eva- poration until the syrup is reduced to eight fluidounces, and while Avarm mix in the reserved Tincture and Extract, and make one pint of Fluid Extract. If necessary, from ten to twenty drops of any desired essential oil, as cloves, mint, or caraway, may be added to cover the taste and prevent nausea or griping. This process is believed to be the best, that can be pursued with the apparatus usually accessible to physicians and apothecaries. But the method pursued by me in preparing these Extracts, Syrups, etc., in larger quantities, secures the object in every respect more perfectly. This con- sists in placing the ingredients, previously ground, and in some cases macerated, into an appropriate vessel, in form like a common displace- ment apparatus or percolator, and driving the Alcohol, Water, or other menstruum, in the state of Vapor, downAvard through them. Steam or the Vapor of Alcohol, penetrates everv fiber of vegetable substances much more readily and perfectly than liquids, and brings all their proximate principles, especially the Resinoids, into a soluble state; but dry steam has no solvent power, it may soften, and expand, and fuse, but it cannot dissolve and carry out those principles, without a liquid as a vehicle. Therefore, to render the process perfect, we must obtain the combined action of Vapor and Liquid. Of Vapor to penetrate and soften, and of Liquid to dissolve and carry out. EXTRACTA FLUIDA. 1069 The steam displacement apparatus, patented by Mr. C. Augustus Smith, is designed to attain this object, but unless the process is con- ducted slowly and with much skill, it is done very imperfect] 3^. For if the vapor be condensed at the top of the apparatus, which will be the case if the surrounding condenser be kept full of cold water as directed, the menstruum will only percolate through in the state of liquid, and will effect no more than if poured on in the state of warm liquid. On the other hand, if the steam be not condensed above, but passes on through the ingredients dry, it affords no vehicle to carry with it the soluble substances. My mode perfects the process by obtaining the con- tinually combined action of the solvent in Vapor and in Fluid. A full description of the apparatus and all the steps of the process in using it, cannot be given here without too greatly extending this article, nor could they be readily understood without the aid of appropriate draw- ings, and must, therefore, be omitted. The lower end of the displacement vessel is connected Avith a worm, so that the liquid is fully condensed and cooled before it comes to the air. If the process be properly conducted the first portions displaced by the vapor will be very strong, and contain most of the Aroma and Essential Oils belonging to the ingredients. Therefore, to prepare a Fluid Extract by this process, of the standard strength of one Fluidounce from one Avoirdupois ounce of the substance, we displace with the Vapor of Alcohol, combined with sufficient Alcohol to serve as a vehicle. Of the first and strongest solution or tincture thus obtained, set aside a portion equal in weight to half the ingredients that are acted on. This contains a large portion of the strength, and nearly all the essential oil and aroma, and is not to be submitted to heat at all. Continue the process until the strength is exhausted, and the liquid comes through but little impregnated with the flavor of the substance. Then turn on the steam of water, until the alcohol remaining in the sub- stance can be driven out and condensed. From this second portion of solution distil off, at a low heat, in vacuo. If the root or other substance is believed to contain any medicinal virtues not soluble in alcohol, then continue the operation with steam of Avater till these are extracted, and evaporate this Avatery solution to a semifluid extract. Mix this and the residuum from which the alco- hol has been distilled, and add refined sugar equal to one-fourth of the ingredients used, and with a moderate heat evaporate the syrup to half the number of pints that there were pounds avoirdupois of the substance operated upon. To this, while simply warm, add the first solution that Avas obtained and set aside, and mix the two thoroughly. Then, if it be necessary, add a few drops of any Essential Oil, as before stated, to cover the taste, etc. Thus making from every pound of ingredients one pint of the fluid extract. It may be asked, why so particular to use very moderate heat, 1070 Pharmacy. or distil in vacuo, to reduce the liquid to the proper quantity, after having acted on it by steam during the process of obtaining it. The reply is: 1st, that the temperature of the Vapor of Alcohol is not so high, by many degrees, as that of Boiling Water; and 2d, it is not the heat itself that destroys these delicate substances, but it is by the combined action of heat and water, and in most cases, of air also, that the more easily destructible proximate principles are oxidized and rendered inert. It is not, therefore, heat alone, but long boiling in water that dissipates all the volatile principles, as the essential oils, and decomposes others, and thus renders extracts prepared in the ordinary way comparatively worthless. All Fluid Extracts are not made according to the above standard of concentration. In the Fluid Extract of Lobelia, all the Alcohol is evapo- rated off, and only the oil and extractive left; this is, therefore, con- densed only two or three ounces from the pound, according to the quality of the seed. In the Fluid Extract of Stillingia, on the other hand, the concentration is less than half that of the above-named standard, as the medicine is so powerful that a greater degree of concentration is not thought expedient. (In the preparation I now make under the name of ' Concentrated Fluid Extracts,' I use Alcohol only, having become satisfied that all the medical virtues of every plant are extracted by that menstruum, if properly managed. And by thus rejecting the starch, gum, and extrac- tive that are dissolved by the water, we are able to make a preparation four times the above strength and still retain its fluidity. In most of our fluid extracts, therefore, each ounce contains the virtues of a quarter of a pound of the ingredients—and some contain much more.— W. S. M.) Medical Syrups are prepared after the same method as the fluid extracts, with the exception that they are less concentrated, and less alcohol and more sugar is employed in their composition. For, as they are taken in proportionably larger doses, the presence of spirit in them Avould be more appreciable and injurious." Extractum Anthemidis Fluidum. Fluid Extract of Chamomile. Preparation. — Take of bruised Chamomile FloAvers twelve ounces; Alcohol, Water, of each, a sufficient quantity. Mix the Chamomile with a sufficient quantity of Alcohol, and allow it to stand for tAventy-four hours ; then transfer it to a percolator and pour Alcohol gradually upon it until a pint and a half of filtered liquid is obtained. Place this in an evaporating dish, and allow it to evaporate spontaneously until reduced to six fluidounces. To the Flowers in the percolator, add gradually a sufficient quantity of Water until it passes without any of the taste of the Chamomile. Evap- orate this portion in a water-bath to six fluidounces. Mix together the alcoholic and aqueous solutions. EXTRACTA FLUIDA. 1071 Properties and Uses.—This Fluid Extract of Chamomile Flowers is tonic, and possesses all the properties of the crude article. Each fluid- ounce of the Extract represents a fluidounce of the Flowers; hence the dose is from half a fluidrachm to a fluidrachm three times a day. It may be advantageously combined with the fluid extracts of cimicifuga, valerian, cypripedium, Scutellaria, etc. Extractum Buchu Fluidum. Fluid Extract of Buchu. Preparation.—Take of the coarsely powdered Leaves of Buchu eight ounces; Ether four fluidounces; Alcohol twelve fluidounces; Diluted Alcohol, or good Holland Gin, a sufficient quantity. Mix the Ether and Alcohol, and having incorporated the Buchu with one-half of the mix- ture, introduce it into a percolator, and gradually pour in the remainder. Then add Diluted Alcohol or good Holland Gin, until the whole liquid which has passed shall amount to a pint. Put the Ethereal Liquid thus obtained into a shallow vessel, and allow it to evaporate spontaneously until reduced to five fluidounces. Upon the mass in the percolator pour gradually Diluted Alcohol or good Holland Gin until ten fluidounces of Tincture have passed. With this mix the five fluidounces left after the spontaneous evaporation, taking care to dissolve in a little Alcohol any oleo-resinous matter which may have been deposited, and to add it to the rest. Allow the mixture to stand, with occasional agitation, for four hours, and then filter. The resulting Fluid Extract should measure a pint; and if it be less than that quantity, the deficiency should be sup- plied by the addition of good Holland Gin. Properties and Uses.—Fluid Extract of Buchu is a gently stimulating diuretic, and may be used in chronic catarrh of the bladder, gravel, morbid irritation of the bladder and urethra, and other affections of the urinary organs. The dose is one or two fluidrachms, three times a day. Extractum Cimicifugae Fluidum. Fluid Extract of Black Cohosh. Preparation.—Take of recently dried Black Cohosh Root, in moder- ately fine powder, sixteen Troy ounces; Alcohol one pint; Ether half a pint; Diluted Alcohol a sufficient quantity. Mix the Cohosh with an equal weight of Sand, moisten it with a portion of the Alcohol, transfer it to a displacement apparatus for volatile liquids, and pour on the remain- der of the Alcohol and the Ether. When the liquid commences to pass, close the orifice so that its passage shall be by drops ; and Avhen the menstruum disappears above, immediately add Diluted Alcohol until the filtered tincture measures a pint and a half. Set this aside in a capsule in a Avarm place until it is reduced to half a pint, and has lost its ethereal odor. Meanwhile, continue the percolation with Diluted Alcohol until two pints more tincture are obtained. Evaporate this in a water-bath to eight fluidounces, and mix it gradually Avith the first product so as to 1072 Pharmacy. avoid as much as possible the precipitation of the resin from the latter. After standing a few hours the Fluid Extract should be filtered, and if it does not measure a pint add a sufficient quantity of Alcohol to mtike that measure. If the amount of resin precipitated is considerable, it may be separated by a cloth-strainer, redissolved in a little Alcohol, and added to the solu- tion, which should then be filtered. History.—This Fluid Extract is prepared after the manner of W. Procter, Jr. It has a dark-reddish brown color like laudanum, is trans- parent, and possesses the bitter, disagreeable taste of the root in a marked degree. Its flavor may be improved by the addition of one pound Avoirdupois of white sugar, and a small portion of some aro- matic essence. Properties and Uses. — The Fluid Extract of Black Cohosh possesses tonic, narcotic, antispasmodic, alterative, and emmenagogue properties. It may be used with advantage in rheumatism, neuralgia, scrofula, syphilis, amenorrhea, dysmenorrhea, chorea, and all diseases in which the Root is indicated. The dose is from half a fluidrachm to two fluidrachms. Extractum Cinchonae Fluidum. Fluid Extract of Cinchona. Preparation.—Take of Calisaya Bark, in a uniform coarse powder, eight troy ounces, moisten it with Diluted Alcohol, and after standing twelve hours, pack the moist Bark properly in a percolator, and pour Diluted Alcohol on it gradually until four pints of tincture have passed, or until its bitterness is exhausted. Evaporate the tincture in a water- bath (or a still), to nine fluidounces; then add of Sugar fourteeen troy ounces, continue the heat until it is dissolved, and strain while hot. Properties and Uses.—Same as Peruvian bark, and may be used alone or in combination with other agents. Dose, one fluidrachm.—A. B. Taylor. Extractum Cornus Floridae Fluidum. Fluid Extract of Dogwood. Preparation.—Take of DogAvood Bark, in coarse poAvder, one pound; Alcohol 76 per cent., four pints; White Sugar six ounces; Water a suffi- cient quantity. Moisten the Bark thoroughly with Alcohol and let it stand for twenty-four hours; then transfer it to a percolator, and gradu- ally add the rest of the Alcohol, returning a little of the first that passes, till it runs clear. Reserve, by itself, of the first running, four fluidounces; evaporate the remaining alcoholic tincture tha1: comes through to four fluidounces, and likeAvise set it aside. To the Powder in the percolator add gradually cold Water a sufficient quantity, until the liquid that passes is but slightly impregnated with the properties of the Dogwood ; evaporate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluid- EXTRACTA FLUIDA. 1073 ounces, and while Avarm, mix in the reserved tincture and extract, and make one pint of Fluid Extract. Properties and Uses.—Fluid Extract of Dogwood is tonic, stimulant, and slightly astringent. It may be used in all cases where tonics are indicated, and Avill be found beneficial in female debility, leucorrhea, etc. The dose is from half a fluidrachm to two fluidrachms. Extractum Cubebae Fluidum. Fluid Extract of Cubebs. Preparation.—"Take of Cubebs, in poAvder, a pound; Ether a sufficient quantity. Put the Cubebs into a percolator, and, having packed it care- fully, pour Ether gradually upon it until two pints of filtered liquor are obtained; then distil off by means of a water-bath, at a gentle heat, a pint and a half of the Ether, and expose the residue in a shallow vessel, until the Avhole of the Ether has evaporated."—U. S. History.—This preparation consists principally of the Aolatile oil and resin of the Cubebs, with some cubebin and waxy matter. Its consis- tence varies according to the amount of volatile oil existing in the Cubebs, and its color is brownish, with more or less of a greenish tint, according to the quantity of chlorophylle present. On long standing, waxy matter and crystals of cubebin are deposited. Properties and Uses.—This preparation possesses the virtues of Cubebs, and may be given in the dose of from five to thirty minims, suspended in water or emulsion, and repeated three times a day. Extractum Cypripedii Fluidum. Fluid Extract of Yellow Ladies' Slipper Root. Preparation.—Take of Yellow Ladies'Slipper Root, in coarse powder, one pound; Alcohol 76 per cent., four pints ; White Sugar sex ounces; Water a sufficient quantity. Moisten the Root thoroughly with some of the Alcohol, and let it stand for twenty-four hours ; then transfer it to a percolator, and gradually add the rest of the Alcohol, returning a little of the first that passes, until it runs clear. Reserve, by itself, of the first running, four fluidounces; evaporate the remaining Alcoholic tincture that comes through to four fluidounces; and likewise set it aside. To the Powder in the percolator add gradually a sufficient quantity of cold Water, until the liquid that passes is but slightly impregnated with the properties of the Cypripedium; evaporate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and Avhile Avarm, mix in the reserved tincture and extract, and make one pint of fluid extract. Properties and Uses.—The Fluid Extract of Cypripedium is tonic, nervine, and antispasmodic, and may be beneficially employed in chorea, hysteria, nervous headache, and all cases of nervous irritability and excitability. A few drops of oil of anise may be added to it to improve its flavor. The dose is from half a fluidrachm to a fluidrachm three times a day.—J. K. 68 1074 Pharmacy. Extractum Epigjeje Fluidum. Fluid Extract of Trailing Arbutus. Preparation.—Take of the recently dried Leaves of Epigaea Repens, in coarse powder, one pound ; Alcohol, 76 per cent., four pints ; White Sugar six ounces; Water a sufficient quantity. Moisten the Leaves thoroughly with some of the Alcohol, and let it stand for twenty-four hours; then transfer it to a percolator, and gradually add the rest of the Alcohol, returning a little of the first that passes, until it runs clear. Reserve, by itself, of the first running, four fluidounces; evaporate the remaining Alcoholic tincture that comes through to four fluidounces, and likeAvise set it aside. To the Powder in the percolator add gradually a sufficient quantity of cold Water, until the liquid that passes is but slightly impregnated with the taste of the Leaves; evaporate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and while Avarm, mix in the reserved Tincture and Extract, and make one pint of Fluid Extract. Properties and Uses.—The Fluid Extract of Trailing Arbutus possesses diuretic and astringent properties, and will be found superior to the preparations of uva ursi, buchu, etc., in gravel, and various other dis- orders of the urinary organs. It may likewise be used in chronic diar- rhea and summer complaint; the dose is one fluidrachm, three or four times a day.—J. K. Extractum ErgotaE Fluidum. Fluid Extract of Ergot. Preparation.—Take of fresh Ergot in powder, eight ounces; Ether four fluidounces ; Alcohol twelve fluidounces, Water a, sufficient quantity. Moisten the Ergot with some of the Ether, let it stand for twenty-four hours, and then transfer to a percolator, and add gradually the remain- der of the Ether. When all has passed through, allow the Ethereal tincture to evaporate spontaneously. To the Powder in the percolator add gradually the Alcohol, and when all has passed, evaporate the filtered tincture to four fluidounces. Again add gradually to the Powder in the percolator, a sufficient quantity of Water, until the liquid passes without the taste of the Ergot; evaporate this liquid to four fluidounces and add to it six ounces of White Sugar, and again evaporate to four fluidounces. Mix the alcoholic and aqueous solutions while hot, and when cold add the residuum of the evaporated Ethereal Tincture, and thoroughly incorporate by agitation. History.—The ether in this preparation takes up a portion of the active principle in combination with the inert fixed oil; while the other agents, undoubtedly, take up certain proportions of the active principle not touched by the ether. The spontaneous evaporation of the ether gives the oil and active principle combined, and which must be well mixed with the other solutions. The heat, in evaporating the alcoholic and aqueous solutions, should be below 212°. As there is yet some doubt in relation Extracta Fluida. 1075 to the active principle of Ergot, a preparation which will represent the drug in its natural form, is desirable, and which is had in this fluid extract. Properties and Uses.—This Fluid Extract may be used as a substitute for ergot in all cases, it is pleasant to the taste, is always ready for use, requires a small dose, and acts promptly without nausea. The dose is from half a fluidrachm to a fluidrachm; the latter dose is about equal to two doses of powdered ergot. Extractum Gentianje Fluidum. Fluid Extract of Gentian. Preparation.—Take of Gentian, in coarse powder, sixteen Troy ounces; French Brandy six fluidounces; Water a sufficient quantity. Macerate the Gentian in two and a half pints of Water for twelve hours, and having introduced it into a percolator, allow the infusion to pass slowly, adding gradually Water until five pints of liquid have passed. Evapo- rate this to ten fluidounces by means of a water bath, add the Brandy, and strain through cotton flannel. History.—This extract has a thin syrupy consistence, a dark brown color, free from sediment, and transparent in thin strata. With water it forms a clear mixture. Properties and Uses.—Tonic, and may be given in doses of from half a fluidrachm to a drachm, which represent half a drachm to a drachm of Gentian Root. It may be variously combined with other agents to meet particular indications. For instance, should an aperient tonic with antacid properties be desired, the following form may be used: Take of Fluid Extract of Gentian, two fluidounces; Fluid Extract of Rhubarb, two fluidrachms; Bicarbonate of Potassa one drachm; Tincture of Ginger two fluidrachms. Mix. One fluidrachm of this mixture will be equal to about forty grains of gentian, six of rhubarb, and three of bicarbonate of potassa. If a chalybeate tonic is desired, the following may be employed : Take of Citrate of Iron and Quinia one drachm; Water six fluidrachms; dissolve and add Fluid Extract of Gentian two fluidounces. A fluid drachm of this mixture will represent about forty-five grains of gentian, and three grains of citrate of iron and quinia. — Wm. Procter, Jr. Extractum Gentians Fluidum Compositum. Compound Fluid Extract of Gentian. Preparation.—Take of Gentian, in coarse powder, sixteen Troy ounces; Bitter Orange Peel, Coriander Seeds, of each, in coarse powder, four ounces; Water, Alcohol, of each, a sufficient quantity. Macerate the Gentian in two and a half pints of water for twelve hours, and introduce it into a percolator ; allow the infusion to pass slowly, adding Water at intervals until five pints of liquid have passed. Evaporate this to ten fluidounces. Macerate the Orange Peel and Coriander Seeds in a mixture of eight fluidounces of Alcohol, and four fluidounces of Water for twelve hours 1076 Pharmacy, introduce them into a percolator, and add gradually a sufficient quantity of Diluted Alcohol to displace twelve fluidounces of tincture. Evapo- rate this to six fluidounces by a gentle heat, (120° F.) add it to the solution of Gentian while hot, and strain. When finished, the Fluid Extract should measure a pint.— Wm. Procter, Jr. History.—The Compound Fluid Extract of Gentian is a colored, thin, syrupy liquid. In the preparation of it I should prefer Prickly Ash Ber- ries to the Coriander, both on account of their flavor, and well known influence on mucous tissues. Properties and Uses.—Tonic and carminative, and may be given in doses of from half a fluidrachm to a fluidrachm. Extractum Hyoscyami Fluidum. Fluid Extract of Henbane. Preparation. — Take of the recently dried Leaves of Henbane, in coarse powder, eight Troy ounces ; Diluted Alcohol a sufficient quantity; Sugar eight Troy ounces. Macerate the Henbane in a pint of Diluted Alcohol for twenty-four hours, transfer it to a percolator, and add gra- dually Diluted Alcohol, until three pints of tincture have passed. Evap- orate the tincture to ten fluidounces, and dissolve the Sugar in it while hot; when cold add Alcohol, sp. gr. 0.835, two fluidounces, or sufficient to make a pint of Fluid Extract, and strain through fine muslin. History.—This forms an elegant and durable preparation of Hyo- scyamus. In percolation the fluid should be allowed to pass very slowly, that thorough exhaustion of the leaves may take place. Properties and Uses.—This extract possesses all the virtues of Hyo- scyamus, and may be given wherever the influence of the plant is desired. The dose is from ten to sixty minims.— C. A. Smith. Extractum Iridis Fluidum. Fluid Extract of Blue Flag. Preparation.—Take of recently dried Blue Flag Root, in coarse pow- der, eight ounces; Ether four fluidounces ; Alcohol twelve fluidounces; Diluted Alcohol a sufficient quantity. Mix the Ether and Alcohol, and having incorporated the Blue Flag with one-half of the mixture, intro- duce the mass into a percolator, and gradually pour in the remainder, Then add Diluted Alcohol until the whole liquid which has passed shall amount to a pint. Put the Ethereal liquid thus obtained into a shallow vessel, and allow it to evaporate spontaneously until reduced to five fluid- ounces. Upon the mass in the percolator pour gradually Diluted Alcohol until ten fluidounces of tincture have passed, and evaporate to five fluid- ounces. With this mix the five fluidounces left after spontaneous evapo- ration, taking care to dissolve in a little Alcohol any oleo-resinous matter which may have been deposited, and to add it to the rest. Allow the mixture to stand, with occasional agitation, for four hours, and filter. The resulting Fluid Extract should be ten fluidounces; and if it be less EXTRACTA FLUIDA. 1077 than that quantity, the deficiency should be supplied by the addition of Alcohol. Properties and Uses.—This holds the virtues of Blue Flag in a con- centrated state, and may be used in syphilis, dropsy, scrofula, and all diseases in which the crude article is indicated. The dose is from ten to thirty minims.—J. K. Extractum LeptandraE Fluidum. Fluid Extract of Black Root. Preparation.—Take of the recently dried Root of Leptandra Virgin- ica, in coarse powder, one pound; Alcohol, 80 per cent., four pints; White Sugar four ounces; Water a sufficient quantity. Add to the Root, in a convenient close vessel, enough Alcohol to thoroughly moisten them, and let the mixture stand for twenty-four hours ; then transfer it to a percolator, and add gradually the rest of the Alcohol, returning a little of the first that comes through, till it runs clear. Reserve, by itself, of the first running, four fluidounces; evaporate the remaining Alcoholic Tincture that comes through to four fluidounces, and likewise set it aside. Then pour Hot Water on the residuum in the percolator, until the liquid that passes has very little of the color or taste of the Blackroot; evapo- rate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and while warm mix in the reserved Tincture and Extract, and make one pint of Fluid Extract. Properties and Uses.—This Extract is laxative, cholagogue, and tonic, and may be advantageously substituted for the Root in all cases. The dose is from ten to sixty minims, one, two, or three times a day. As a laxative it is preferable to Leptandrin.—J. K. Extractum Lobeliae Fluidum. Fluid Extract of Lobelia. Preparation.—Mr. Procter employs the following process in preparing a Fluid Extract of Lobelia Herb: Macerate for twenty-four hours, Lobelia, finely bruised, in Diluted Alcohol one pint and a half, and Acetic Acid one fluidounce ; introduce the mixture into an earthen displacer, and pour on slowly Diluted Alcohol one pint and a half, and afterward Water until three pints of tincture are obtained; evaporate this in a water-bath to ten fluidounces, strain, add Alcohol six fluidounces, and when mixed filter through paper. This process is based on the fact, that in the presence of an excess of acid, the lobelina of the natural salt, which gives activity to the drug, is not decomposed and destroyed by the heat used. A fluidrachm of this extract is equal to half a fluidounce of the tincture. That which is commonly used by Eclectics is prepared according to the previous instructions by W. S. Merrell. Properties and Uses.—The Fluid Extract of Lobelia possesses all the properties of the plant in a concentrated degree. It may be used wherever lobelia is indicated. The dose is from five minims to a 1078 Pharmacy. fluidrachm, according to the effect required ; and which are equivalent to five grains or a drachm of the powder. Extractum Lobeliae Fluidum Compositum. Compound Fluid Ex- tract of Lobelia. Preparation.—Take of the recently dried Bloodroot, Skunkcabbage Root, and Lobelia Seeds and Leaves, of each, coarsely powdered, five ounces and a half; Alcohol, 80 per cent, four pints ; White Sugar four ounces ; Water a sufficient quantity. Moisten the articles mixed together with sufficient Alcohol, and let them stand for twenty-four hours ; then transfer the mixture to a percolator, and gradually add the rest of the Alcohol, returning a little of the first that passes, till it runs clear. Re- serve, by itself, of the first or strongest running, four fluidounces ; evap- orate the remaining Alcoholic tincture that comes through to four fluid- ounces, and likewise set it aside. Then pour Hot Water on the residuum in the percolator, until the liquid that comes through has very little of the color or taste of the medicine ; evaporate this latter solution to half a pint, by a heat considerably below the boiling point, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluid- ounces, and while warm mix in the reserved tincture and extract, and make one pint of Fluid Extract. Properties and Uses.—This fluid extraot is emetic, expectorant, and antispasmodic, and may be used as a substitute for the Acetated Tinc- ture of Bloodroot. A fluidrachm of the extract is equivalent to about a drachm of the powder; the dose is from ten to sixty minims according to the desired effect.— W. S. M. Extractum Polygoni Fluidum.

Preparation.—Take of Rhubarb, in coarse powder, eight ounces ; Sugar five ounces; Tincture of Ginger lialf a fluidounce; Oil of Fennel, Oil of Anise, each four minims ; Diluted Alcohol a sufficient quantity. To the Rhubarb, previously mixed with an equal bulk of coarse Sand, add twelve fluidounces of Diluted Alcohol, and allow the mixture to stand for twenty- four hours. Transfer the mass to a percolator, and gradually pour upon it Diluted Alcohol until the liquid which passes has little of the odor or taste of Rhubarb. Evaporate the tincture thus obtained, by means of a water-bath, to five fluidounces ; then add the Sugar, and, after it is dis- solved, mix thoroughly with the resulting Fluid Extract, the Tincture of Ginger holding the oils in solution.— U. S. Properties and Uses.—This forms a good preparation of Rhubarb, the root being nearly exhausted by the menstruum, and the active principles not being injuriously affected, if the evaporation be carefully conducted, without too great a degree of heat. The dose is half a fluidrachm for an adult, which is equivalent to half a drachm of rhubarb. This is inapplicable to acute inflammatory affections, on account of the stimulus it contains, in the alcohol and oils. Extractum Rhei et Potassae Fluidum. Fluid Extract of Rhubarb and Potassa. Fluid Neutralizing Extract. Preparation.—Take of the Root of the best India Rhubarb, and Bi- carbonate of Potassa, of each, two pounds Avoirdupois ; Cassia or Cinna- mon, and Golden Seal, of each one pound; good French Brandy, fourth proof, one gallon; Oil of Peppermint one fluidrachm; Refined Sugar three pounds ; Water a sufficient quantity. Grind, or coarsely bruise the Rhubarb, Cassia, and Golden Seal, and mix them. Macerate them for twenty-four hours, or longer in the Brandy ; then express the tincture with strong pressure, and add to it the Oil of Peppermint previously dis- solved in a little Alcohol. Break up the cake, or compressed residue from the press, place it in a percolator, and gradually add warm Water, until the strength of the articles is exhausted. Evaporate this solution to four pints, and while the liquor is still hot, dissolve in it the Bicarbo- nate of Potassa and Refined Sugar. Continue the evaporation, if neces- rary, until, when added to the tincture first obtained, it will make one gallon and a half of Fluid Extraet, aud mix the two solutions together. In adding the Bicarbonate of Potassa the liquid must not be too hot else it will be converted into the sesquicarbonate. Properties and Uses.—This is an elegant and superior preparation, being an improvement upon the Neutralizing Cordial. It is used for the same diseases as the Compound Powder of Rhubarb, and is a more eli-1 gible form of administration. Two fluidrachms of this Fluid Extract are equivalent to one drachm of the powder.— W. S. M. 1080 Pharmacy. Extractum Rhus Fluidum. Fluid Extract of Sumach. Preparation. — Take of the recently dried Bark of Rhus Glabrum, in coarse powder, one pound; Alcohol, 76 per cent., four pints; White Sugar four ounces; Water a sufficient quantity. Add sufficient Alcohol to the Bark to thoroughly moisten it, and let it macerate for twenty-four hours ; then transfer the mixture to a percolator, and gradually add the rest of the Alcohol, returning a little of the first that passes, till it runs clear. Reserve, by itself, of the first running, four fluidounces ; evapo- rate the remainder of the Alcoholic tincture that passes, to four fluid- ounces, and likewise set it aside. Then pour Hot Water on the residuum in the percolator, until the liquid that comes through has very little of the taste of the Sumach ; evaporate this latter solution to half a pint, then add the sugar; continue the evaporation until the syrup is reduced to eight fluidounces, and while warm mix in the reserved tincture and extract, and make one pint of Fluid Extract. Properties and Uses.—The Fluid Extract of Sumach is tonic, astringent, and antiseptic. It will be found beneficial in scrofula, gonorrhea, diar- rhea, dysentery, and in mercurial sore mouth and salivation. The dose is from half a fluidrachm to a fluidrachm, three times a day. Extractum Sarsaparillae Fluidum Compositum. Compound Fluid Extract of Sarsaparilla. Preparation. — Take of Sarsaparilla Root, sliced and bruised, sixteen « ounces; Liquorice root, bruised, Bark of Sassafras Root, bruised, of each, two ounces; Mezereon, sliced, six drachms; Diluted Alcohol eight pints; White Sugar twelve ounces. Macerate all the articles together, excepting the Sugar, for fourteen days ; then express and filter. Evaporate the tincture, by means of a water bath, to twelve fluidounces, and add the Sugar to it while hot. Remove from the bath as soon as the Sugar is dissolved. Properties and Uses. — This fluid extract is alterative, and maybe used in serofula and secondary syphilis. The dose is a fluidrachm, which is equivalent to a drachm of the root, three or four times a day. With the exception of the omission of Guaiacum Wood, this formula is the one proposed by W. Hodgson, Jr. Extractum Scutellariae Fluidum. Fluid Extract of Scullcap. Preparation.—Take of the recently dried Leaves of Scullcap, in coarse powder, one pound; Alcohol, 76 per cent., four pints; White Sugar four ounces; Water a sufficient quantity. Add a sufficient quantity of the Alcohol to the Scullcap to thoroughly moisten it, and alloAv the mixture to macerate for twenty-four hours ; then transfer it to a perco- lator, and gradually add the rest of the Alcohol, returning a little of the first that comes through, till it runs clear. Reserve, by itself, of the first running, four fluidounces ; evaporate the remaining Alcoholic tincture that passes to four fluidounces, and likewise set it aside. Then 'EXTRACTA FLUIDA. 1081 pour gradually on the residuum in the percolator a sufficient quantity of Hot Water, until the liquid that passes is but slightly impregnated Avith the properties of the Scullcap ; evaporate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and while warm mix in the reserved tinc- ture and extract, and make one pint of Fluid Extract. Properties and Uses.—Fluid Extract of Scullcap is tonic, nervine, and antispasmodic, and is a very convenient and eligible form of administering the active principles of the plant. It may be used in all cases where the herb is indicated. The dose is from half a fluidrachm to a fluidrachm, three or four times a day.—J. K. Extractum Senecii Fluidum. Fluid Extract of Life-root. Preparation. — Take of the recently dried Herb Senecio Aureus, in coarse powder, one pound; Alcohol, 76 per cent., four pints; White Sugar four ounces; Water a sufficient quantity. Add a sufficient quan- tity of the Alcohol to the Herb to thoroughly moisten it, and allow the mixture to macerate for twenty four hours ; then transfer it to a perco- lator, and gradually add the rest of the Alcohol, returning a little of the first that passes, till it runs clear. Reserve, by itself, of the first running, four fluidounces ; evaporate the remaining Alcoholic tincture that passes to four fluidounces, and likewise set that aside. Then pour gradually on the residuum in the percolator a sufficient quantity of Hot Water, until the liquid that passes is but slightly impregnated with the properties of the Life-root Herb ; evaporate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and while warm mix in the reserved tincture and extract, and make one pint of Fluid Extract. Properties and Uses.—This Fluid Extract possesses the medical vir- tues of the Life-root, and forms a useful agent in amenorrhea, either alone, or in combination with the fluid extracts of black cohosh, water- pepper, etc. It may, likewise, be used advantageously in the other diseases in which the root is round efficient. The dose is from half a fluidrachm to a fluidrachm; three or four times a day.—J. K. Extractum Sennae Fluidum. Fluid Extract of Senna. Preparation. — Take of Senna, in coarse powder, two pounds and a half; Sugar twenty ounces; Oil of Fennel a fluidrachm; Hoffman's Ano- dyne two fluidrachms ; Diluted Alcohol four pints. Macerate the Senna with the Diluted Alcohol for twenty-four hours, then introduce the mix- ture into a percolator, and gradually add Water mixed with one-third of its bulk of Alcohol, until a gallon and a half of liquid shall have passed. Evaporate the liquid by means of a water-bath to twenty fluid- ounces ; filter, add the Sugar while the Fluid is hot, and when it is all dissolved, add the Oil of Fennel dissolved in Hoffman's Anodyne. 1082 Pharmacy. Properties and Uses. — This forms a neat preparation of Senna ; the addition of Hoffman's Anodyne is to prevent fermentation. The dose for an adult is half a fluidounce.—Duhamel. Extractum Sennae et Jalapae Fluidum. Fluid Extract of Senna and Jalap. Fluid Extract of Antibilious Physic. Preparation.—Take of Senna, in coarse powder, one pound; Jalap Root, in coarse powder, half a pound; Alcohol, 76 per cent., six pints; Carbonate of Potassa six drachms; White Sugar eight ounces ; Diluted Alcohol a sufficient quantity; Oil of Cloves forty minims; Hoffman's Anodyne one fluidrachm and a half. Mix the Senna and Jalap together, and add a sufficient quantity of Alcohol to thoroughly moisten them, and let the mixture stand for twenty-four hours ; then transfer it to a perco- lator, and gradually add the rest of the Alcohol, returning a little of the first that passes, till it runs clear. Reserve, by itself, of the first running, six fluidounces ; evaporate the remaining Alcoholic tincture that comes through to six fluidounces, and likewise set it aside. Then add a sufficient quantity of Diluted Alcohol to the residuum in the percolator, until the liquid passes but very little impregnated with the properties of the medicines; evaporate this latter solution to twelve fluidounces, then add the Sugar, and continue the evaporation until the syrup is reduced to twelve fluidounces, and while warm add the Car- bonate of Potassa, the Oil of Cloves previously dissolved in Hoffman's Anodyne, also the reserved tincture and extract, and make one pint and a half of Fluid Extract. Properties and Uses.—This is a concentrated form of the Compound Powder of Jalap, and may be given with safety in all cases where a purgative is required. Should any resinous matter be deposited, it must be dissolved in Alcohol and combined with the extract; the addition of the Carbonate of Potassa is to enable the resinous matter deposited during evaporation, to be dissolved, also to aid in counteracting the griping property of the medicine. The dose for an adult is a fluidrachm, which is about equivalent to one drachm of the powder.— W. S. M. Extractum Sennae et Rhei Fluidum. Fluid Extract of Senna and Rhubarb. Preparation.—Take of Senna, in coarse powder, twelve ounces (Troy); Rhubarb, in coarse powder, four ounces; Bicarbonate of Potassa half an ounce; Sugar eight ounces; Tincture of Ginger a fluidounce; Oil of Cloves eight minims; Oil of Anise sixteen minims; Alcohol, and Water, of each, a sufficient quantity. Mix the Senna and Rhubarb together, pour upon them two pints of Diluted Alcohol, and allow them to mace- rate for twenty-four hours; then introduce the mixture into a percolator furnished below with a stop-cock or cork to regulate the flow. A mix- ture of one part of Alcohol and three of Water should now be gradually added, so as to keep a constant but slow displacement of the absorbed EXTRACTA FLUIDA. 1083 menstruum, until one gallon of tincture has passed. Evaporate this in a water-bath to eleven fluidounces, dissolve in it the Sugar and Bicar- bonate of Potassa, and after straining, add the Tincture of Ginger holding the Oils in solution, and mix. When finished the whole should measure a pint. History.—If the percolation has been properly conducted, the ingre- dients will have been sufficiently exhausted when six pints of fluid have passed. As by far the larger portion of the soluble matter passes in the first two pints, it is well to set these aside and evaporate them separately to six fluidounces, subsequently adding it to the other liquid when it has been reduced to five fluidounces. As the cathartic principles of senna and rhubarb are very susceptible to injury from heat, especially in contact with the air, the propriety of using the best available means for con- ducting the evaporation need not be urged. When the evaporation is conducted in open vessels, some advantage is gained by adding the sugar to the tincture and continuing the process until it measures fifteen fluidounces. The sugar protects the extractive matter from oxidation, and more completely suspends or dissolves the resinous part of the rhu- barb contained in the tincture. The bicarbonate of potassa should not be added to the extract while it is above 140° F., and should be reduced to powder previously. Properties and Uses.—Senna has little, if any, tonic influence on the alimentary surfaces; an overdose has a depleting effect, often inconve- nient, and its exhibition is frequently attended with griping. Rhubarb, on the other hand, possesses both a purgative and astringent property, the latter coming into play after the former has manifested itself, and thus repairing, as it were, its effects. This astringent or tonic action of rhubarb is so strongly marked, that, in most cases, when a simple cathartic is needed, it becomes necessary to combine this drug with some other cathartic to overcome or modify this peculiarity. By the union of senna and rhubarb in the concentrated form presented by a fluid extract, and in a due proportion, a resulting cathartic is obtained which is safe, unattended by unpleasant symptoms, and not folloAved by constipation when the dose has been properly graduated. The association of alkalies and alka- line salts with rhubarb and senna, has a tendency to prevent their griping, and in the case of senna, to increase its activity. The dose of this fluid extract, for an adult, is from half a fluidrachm to a fluid drachm.— Wm. Procter, Jr. Extractum Serpentariae Fluidum. Fluid Extract of Virginia Snakeroot. Preparation. — Take of Virginia Snakeroot, in coarse powder, twelve ounces; Alcohol and Water, of each, a sufficient quantity. Mix the Ser- pentaria with twelve ounces of Alcohol, and allow it to stand for twenty- four hours; then transfer it to a percolator and gradually add Alcohol 1084 Pharmacy. until a pint and a half of filtered liquor is obtained. Place this in an evaporating dish, and allow it to evaporate spontaneously until reduced to six fluidounces. To the root in the percolator, exhausted by alcohol, add gradually a sufficient quantity of Water, until it is exhausted, or until about three pints have passed; (to which, if required, Sugar six ounces may be added and dissolved). Evaporate this last aqueous solution in a water-bath, to six fluidounces, and while warm, add the six fluidounces obtained by spontaneous evaporation of the alcoholic tincture, mix together, and strain. Properties and Uses.—This fluid extract forms a useful tonic, which may be used in cases where the root is admissible. Each ounce of it represents an ounce of the root. The dose is from fifteen to forty-five minims, three or four times a day.—A. B. Taylor. Extractum SpigelIaE et Sennae Fluidum. Fluid Extract of Spige- lia and Senna. Preparation. — Take of Pink Root, in coarse powder, one pound; Senna, in coarse powder, six ounces ; Sugar one pound and a half; Car- bonate of Potassa six drachms; Oil of Caraway, Oil of Anise, of each, half a fluidrachm; Diluted Alcohol a sufficient quantity. Macerate the Pink Root and Senna for two days, with Diluted Alcohol two pints; then transfer the mixture to a percolator, and gradually add Diluted Alcohol, until half a gallon of liquid has passed. Evaporate the tincture thus obtained, by means of a water-bath, to a pint; then add the Carbonate of Potassa, and after it has dissolved the resinous sediment, add the Sugar previously triturated with the Oils, effecting its solution by a gentle heat.— U. S. Properties and Uses.—This fluid extract combines the cathartic pro- perties of senna, with the anthelmintic virtues of pink root; it is not offensive to the taste, and is generally acceptable to the stomach. The dose is half a fluidounce for an adult; a fluidrachm for a child two years old. Extractum Stillingiae Fluidum. Fluid Extract of Queen's Root. Bronchial Elixir. Preparation.—Take of the recently gathered Root of Stillingia, cut into small pieces, one pound; Alcohol, 76 per cent., four pints; White Sugar eight ounces; Oil of Caraway a fluidrachm; Water a sufficient quantity. Cover the Root with Alcohol, and let the mixture stand for twenty-four hours; then transfer it to a percolator, so packed as to admit of a slow running, and add gradually the remainder of the Alcohol, returning a little of the first that passes, till it runs clear. Reserve, by itself, of the first running, four fluidounces; evaporate the remainder of the Alcoholic tincture that comes through to four fluidounces, and like- wise set it aside. Then pour Hot Water on the residuum in the percola- tor, until the liquid that comes through is but slightly impregnated with EXTRACTA FLUIDA. 1085 the properties of the Stillingia; evaporate this solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and while warm, mix in the reserved tincture and extract, and then the Oil of Caraway, and make one pint of Fluid Extract. Properties and Uses.—This fluid extract possesses all the active pro- perties of the Queen's Root, in a concentrated form, one fluidrachm being equal to one drachm of the root. On account of its great activity it is never used in scrofula, syphilis, etc., in which the more agreeable and sufficiently active and efficacious Compound Syrup of Stillingia is preferred. It has been, however, found very efficient in bronchitis, laryngitis, and various pulmonary affections. The dose is from two to five or ten drops, to be placed upon the tongue, and allowed to pass very slowly into the stomach.— W. S. M. Extractum Taraxaci Fluidum. Fluid Extract of Dandelion. Preparation.—Take of the recently-dried Root of Dandelion, in coarse powder, four pounds; Alcohol twelve fluidounces; Sugar two pounds; Water a sufficient quantity. Moisten the root with Cold Water, and let it stand for twenty-four hours; then express, filter, add the Alcohol, and set the liquid aside. Break up the cake produced by the pressure, cover it with Cold Water, and let it stand twenty-four hours; again ex- press, filter, and add the Sugar to the liquid. Evaporate in shallow vessels by means of a water-bath, to a quantity that shall just make forty-eight fluidounces on the addition of the first reserved solution, and mix the two liquors. History. — Dandelion is very much injured in its medicinal properties by heat, hence, the importance of employing as little heat in makino- the above fluid extract as possible. Mr. Wm. Procter, Jr., offers the fol- lowing mode of obtaining the virtues of dandelion, by which the natural juice may be preserved unimpaired: Take of fresh Dandelion Roots (collected in September or October) twenty pounds, Avoirdupois; Alco- hol, sp. gr. 0.835, four pints. Slice the roots transversely in short sections, and by means of a mill or mortar and pestle reduce them to a pulpy mass; then add the Alcohol and mix them thoroughly. The mixture thus far prepared at the season when the root is proper for collection, may be set aside in suitable vessels; stoneware jars are appropriate; and extracted as the preparation is needed through the other seasons. After having stood a week, or until a convenient time, the pulpy mass is subjected to powerful pressure, until as much as pos- sible of the fluid is removed. This is then filtered and bottled for use. It is necessary that sufficient time should elapse after the pulp is set aside, for the alcohol to penetrate the fibrous particles and commingle with the natural juices, as Avell as for the Avoody structure of the root to lose its elasticity, that it may yield the juice more completely on pres- sure. When the pulp has stood six months in this manner it yields the 1086 Pharmacy. juice with great readiness, and is possessed of the sensible properties of the dandelion in a marked degree. When eight pounds, Avoirdupois, of the root is thus treated, after standing several months, the practical result is about six pints of fluid, with an ordinary screw-press. This yield will vary in amount with the condition of the root when collected, and the length of time it is exposed afterward, as well as the power of the press used. Should the alcohol in this preparation be contra-indi- cated, it might be partially removed by exposure in a water-bath until the juice was reduced to five-sixths of its bulk, and then for every pint of the residue, eight ounces, Troy, of Sugar may be added and dis- solved in it. Properties and Uses.—Fluid Extract of Dandelion may be administered in all cases when the influence of this drug upon the system is desired. The dose is one or two fluidrachms three times a day. Some practi- tioners speak very highly of the therapeutical influence of dandelion ; others, myself among the number, do not; probably, in the latter instances, the cause may exist in using preparations rendered inert by the heat employed in their manufacture. Extractum Valerianae Fluidum. Fluid Extract of Valerian. Preparation. — "Take of Valerian, in coarse powder, eight ounces; Ether four fluidounces; Alcohol twelve fluidounces; Diluted Alcohol a sufficient quantity. Mix the Ether and Alcohol, and having incorporated the Valerian with one half of the mixture, introduce the mass into a percolator, and gradually pour in the remainder. Then add Diluted Alcohol until the whole liquid which has passed shall amount to a pint. Put the ethereal liquid thus obtained into a shallow vessel, and allow it to evaporate spontaneously until reduced to five fluidounces. Upon the mass in the percolator pour gradually Diluted Alcohol until ten fluid- ounces of tincture have passed. With this mix the five fluidounces left after the spontaneous evaporation, taking care to dissolve in a little Alcohol any Oleo-resinous matter which may have been deposited, and to add it to the rest. Allow the mixture to stand, with occasional agita- tion, for four hours, and then filter. The resulting Fluid Extract should measure a pint; and if it be less than that quantity, the deficiency should be supplied by the addition of alcohol." — U. S. Properties and Uses.—This holds the virtues of Valerian in a con- centrated state, and may be used when desired to obtain the influence of that agent. It may also be combined with various other fluid extracts, as of cimicifuga, cypripedium, senecio, etc. The dose is one or two fluidrachms, three times a day, or oftener if required. Extractum Xanthoxyli Fluidum. Fluid extract of Prickly Ash. Preparation.—Take of Prickly Ash Bark, in coarse powder, one pound; Alcohol, 76 per cent., four pints; White Sugar four ounces ; Di- luted Alcohol a sufficient quantity. Moisten the bark thoroughly with Ferrum. 1087 Alcohol, and let it stand twenty-four hours; then transfer the mixture to a percolator, and gradually add the rest of the Alcohol, returning a little of the first that passes, till it runs clear. Reserve, by itself, of the first running four fluidounces; evaporate the remaining Alcoholic tincture that comes through to four fluidounces, and likewise set it aside. Then add a sufficient quantity of Diluted Alcohol to the residuum in the per- colator, until the liquid that comes through has very little of the taste of the medicine; evaporate this latter solution to half a pint, then add the Sugar, continue the evaporation until the syrup is reduced to eight fluidounces, and while warm mix in the reserved tincture and extract, and make one pint of Fluid Extract. Properties and Uses.—Fluid Extract of Prickly Ash Bark is a stimu- lant, tonic, alterative, and sialogogue, and may be used in all cases where the bark is indicated or desired. The dose is from ten to thirty minims, three times a day.—J. K. FERRUM. Preparations of Iron. Ferri Acetas. Acetate of Iron. Preparation.—Take of Carbonate of Iron one ounce; Acetic Acid six ounces. Digest for three days, and filter. History.—This solution has a deep red color, and an acid and strongly chalybeate taste. It is incompatible with alkalies and their carbonates, the strong acids, and vegetable astringent infusions. Properties and Uses.—Tonic and astringent, and possesses the general medical properties of the preparations of iron. A diluted solution of it, with a few drops of creosote, will be found a valuable injection in leu- corrhea. Dose, five to twenty drops, in water. (See Tinctura Ferri Acetatis.) Ferri Carbonas Saccharatum. Saccharine Carbonate of Iron. Preparation.—Take of Sulphate of Iron four ounces ; Carbonate of Soda/bar ounces and a quarter; Sugar two ounces; Boiling Distilled Water four pints, Imperial measure. Dissolve separately the Sulphate of Iron, and Carbonate of Soda, each in two pints of the Water. Mix the solutions while still hot, and set the mixture aside, that the Carbonate of Iron may subside. Then, having poured off the supernatant liquor, wash frequently the precipitated Carbonate. To this add the Sugar, dissolved in two fluidounces of Water, and evaporate the mixture by means of a water-bath until the powder is dry. Keep this in a Avell stopped bottle.—Lond. History. —When a solution of sulphate of iron is mixed with a solu- tion of carbonate of potassa, a double decomposition ensues, resulting in a precipitate of carbonate of protoxide of iron, which falls of a pale- bluish color, and sulphate of soda, which remains in solution. The 1088 Pharmacy. precipitate formed by this action, absorbs oxygen very rapidly Avhen exposed to the air, and soon changes into the sesquioxide of iron, which together with its preparations are not so much esteemed in medicine as the protoxide and its preparations. The sesquioxide formed from this preci- pitate usually retains some of the carbonate of the protoxide which has remained unchanged. As saccharine matter prevents the absorption of oxygen, and consequently preserves the carbonate of the protoxide of iron from passing into sesquioxide, sugar is added to effect this object. Saccharine Carbonate of Iron is of a grayish-green color, with a sweet and strongly chalybeate taste, is permanent in the air, and readily dissolves in muriatic acid with effervescence. Properties and Uses.—This forms an excellent chalybeate tonic, and is superior to the subcarbonate of iron, but inferior to Vallet's Ferru- ginous mass, which has the advantage of being prepared with the anti- oxidizing influence of sugar from the commencement. ( See Pilula; Ferri Carbonalis.) The stools are rendered greenish-black by its use. The dose is five to thirty grains, in the form of pill. Ferri Citras. Citrate of Iron. Preparation.—Take of Citric Acid five ounces and a half; Distilled Water five fluidounces; moist Hydrated Oxide of Iron (prepared accord- ing to the formula given hereafter), a sufficient quantity. Dissolve the Acid in the Water, in a platinum capsule ; heat the Solution to about 150°, maintain it at this temperature, and gradually add the Hydrated Oxide, in its moist and recent state, as long as any is dissolved, and until the Acid is fully saturated. Filter the liquid, and evaporate it to the consistence of thick molasses. Then spread it out thinly on glass or porcelain plates, where it speedily dries in thin layers, which are to be detached from the plates, and broken into fragments. History.—In this process, the temperature directed promotes the solution of the sesquioxide ; while a higher temperature would lessen its solubility. Citrate of Iron, is of a beautiful garnet-red color, un- crystallizable, slowly soluble in cold water, but readily soluble in boiling water, with an acid, not unpleasant chalybeate taste. It consists of one equivalent of Citric Acid 165, and one of Sesquioxide of Iron 80=245. When the excess of acid in this salt is neutralized by adding Solution of Ammonia to its solution, the double salt, called Ammonio-citrate of Iron (Ferri Ammonio-Citras), is formed in solution. By evaporating this to the consistence of syrup, pouring it in thin layers on earthenware plates, and drying with a gentle heat, the salt is obtained in scales. The heat, however, drives off a great portion of the Ammonia. Ammo- nio-citrate of Iron is in scales of a garnet-red color, much more readily soluble in cold water than the Citrate of Iron, and possesses an acidu- lous, slightly chalybeate taste. Potassa and lime-water decompose it, with evohuion of ammonia, and a precipitate of the sesquioxide of iron; ferrocyanuret of potassium does not render it blue. Ferrum. 1089 Properties and Uses.—These salts are pleasant chalybeate tonics, and may be given in doses of from four to ten grains of either, in pill or solu- tion, and repeated four or five times a day. The citrate is best given in the form of pill. Ferri et Quiniae Citras. Citrate of Iron and Quinia. Preparation.—Take of Citrate of Iron five ounces; recently precipi- tated Quinia one ounce ; Citric Acid two drachms; Distilled water twelve fluidounces. Mix these together in a capsule, and apply heat, but not sufficient to produce ebullition; stir constantly. When the articles are all dissolved, evaporate the solution carefully to the consistence of syrup, and spread it in thin layers on glass, to dry. History.—Citrate of Iron and Quinia is in the form of scales, which are shining, and of a more or less deep garnet-color. It may also be made in the following manner; Dissolve Citrate of Iron four parts, Citrate of Quinia, one part, in Distilled Water, and evaporate the solution to dryness, as directed for Citrate of Iron. Properties and Uses. — A valuable tonic. Dose, five to ten grains, three times a day, either in solution or pill. Ferri et Morphiae Tartras. Ferrotartrate of Morphia. Tartrate of Iron and Morphia. Preparation.—Tnke of crystallized Tartaric Acid, Distilled Water, each, by weight, two ounces; moist Hydrated Sesquioxide of Iron, pure Morphia, of each, a sufficient quantity. Boil the Tartaric Acid and the Distilled Water together, in a glass or platina vessel; as soon as the Acid is dissolved, add the Iron until the fluid will dissolve no more. Heat the mixture until the deep blood-red fluid becomes clear, and then add the Morphia until the fluid ceases to dissolve it. Evaporate the solution by means of gentle heat, to the consistence of thick syrup, and spread it in thin layers on glass, to dry. History.—This salt was first prepared by Professor J. Milton Sanders, formerly Professor of Chemistry in the Eclectic Medical Institute of Cincinnati, and previously my colleague in the Memphis Institute. It is in pellicles of a deep crimson color, and belongs to that class of non- crystallizable or factitious salts, as the Ferro-citrate of Iron and Quinia, so popular with the Medical profession for the last eight or ten years; on account of its ready solubility and promptness of action it is much employed among Eclectics, with whom it constitutes a valuable agent. It is incompatible with astringent vegetable infusions, strong acids, alka- lies, and their carbonates. Properties and Uses.—This salt is an active and efficient tonic and sedative, and may be employed in all cases of debility, chlorosis, anemia, etc., connected with an irritable or excitable condition of the system. In the intermission or remission of fevers, it may be used with much advan- tage, assisting materially in lessening the severity of the subsequent 69 1090 Pharmacy. febrile exacerbations, or breaking them up entirely. Professor Z. Free- man, myself, and various other practitioners have administered it with much benefit. The dose for an adult is from half a grain to a grain, every two or three hours, or until its sedative influence is fully obtained. Ferri et Quiniae Tartras. Ferrotartrate of Quinia. Tartrate of Iron and Quinia. Preparation. — Take of Crystallized Tartaric Acid, Distilled Water, each, by weight, two ounces; moist Hydrated Sesquioxide of Iron, pure Quinia, of each, a sufficient quantity. Boil the Tartaric Acid and the Dis- tilled Water together, in a glass or platina vessel; as soon as the Acid is dissolved, add the Iron as long as the fluid will dissolve it. Heat the mixture until the deep blood-red fluid becomes clear, and then add the Quinia until the fluid ceases to dissolve it. Evaporate the solution by means of gentle heat, to the consistence of thick syrup, and spread it in thin layers on glass, to dry. History.—This salt was, likewise, first prepared by Professor J. Milton Sanders, and is superior to the Citrate of Iron and Quinia, on account of its greater solubility, and its activity as a remedial agent. It forms into scales of a beautiful crimson color. It is incompatible with astrin- gent vegetable infusions, strong acids, alkalies, and their carbonates. Properties and Uses.—The Ferrotartrate of Quinia !% a valuable tonic, and may be used with benefit in chlorosis, amenorrhea, debility, anemia, and during the remissions or intermissions from fever; also in scrofula, and wherever the union of quinia with a chalybeate is indicated. The dose is from three to five grains, three times a day, either in solution, or in the form of pill. Ferri et SalicinIaE Tartras. Ferrotartrate of Salicin. Tartrate of Iron and Salicin. Preparation.—Take of Crystallized Tartaric Acid, Distilled Water, each, by weight, two ounces ; moist Hydrated Sesquioxide of Iron, pure Salicin, of each, a sufficient quantity. Boil the Tartaric Acid and the Dis- tilled Water together in a glass or platina vessel; as soon as the Acid is dissolved, add the Iron as long as the fluid will dissolve it. Heat the , mixture until the deep blood-red fluid becomes clear, and then add the Salicin until the fluid ceases to dissolve it. Evaporate the solution by means of gentle heat, to the consistence of thick syrup, and spread it in thin layers on glass, to dry. History.—This salt was first prepared by Professor J. M. Sanders. Although Salicin appears to be a neutral substance, still, prepared ac- cording to the above process, it enters into combination with the other agents, forming a compound which possesses the active virtues of the Salicin in a remarkable degree. It is incompatible with astringent vege- table infusions, strong acids, alkalies, and their carbonates. Ferrum. 1091 Properties and Uses.—Similar to those of the Ferrotartrate of Quinia. In the hands of several physicians of the South, this preparation has been found equal to the analogous one of Quinia in intermittent fevers. The dose is from three to ten grains, three times a day, either in solution or in the form of pill. Ferri Ferrocyanuretum. Ferrocyanuret of Iron. Pure Prussian Blue. Prussiate of Iron. Preparation.—Take of Sulphate of Iron, four ounces ; Sulphuric Acid three fluidrachms and a half; Nitric Acid six fluidrachms or a sufficient quantity ; Ferrocyanuret of Potassium four ounces and a half; Water two pints. Dissolve the Sulphate of Iron in a pint of the Water, and having slowly and carefully added the Sulphuric Acid, boil the solution. Pour into it the Nitric Acid gradually and in small portions, boiling the liquid for a minute or two after each addition, until a dark color is no longer produced; then allow it to cool. Dissolve the Ferrocyanuret of Potas- sium in the remaining pint of Water, and add this solution gradually to the first liquid, agitating the mixture after each addition ; then pour it upon a filter. Wash the precipitate with boiling water until the wash- ings pass tasteless. Lastly, dry it and rub it into powder.— U. S. History.—In the above process, the Sulphate of Iron (protoxide) is acidulated with sulphuric acid, and then, on the addition of nitric acid is changed into the tersulphate of iron (sesquioxide). The saturating power of the sesquioxide over the protoxide, is increased by the addition of the sulphuric acid, and thus a precipitate of the subsulphate of the sesquioxide is prevented. By the addition of the solution of the ferro- cyanuret of potassium to that of the tersulphate of the sesquioxide of iron, a decomposition ensues; three equivalents of the former, and two of the latter are mutually decomposed, giving rise to one equivalent of Prussian blue, which precipitates, and six equivalents of sulphate of potassa, in solution. Prussian blue contains tt^elements of six equiva- lents of water, and the salt is decomposed when these are separated. It may therefore, as a hydroferrocyanate of the sesquioxide of iron, be rep- resented by the formula 3 Cfy Hi, Fei 03; and the anhydrous com- pound, which contains nine equivalents of cyanogen, and seven of iron, by 3 Cfy, 4 Fe. Gregory gives as the true formula of Prussian blue, Cfya Kg + Fei Cla = 6 K CI + Cfys Fe4. When manufactured on a large scale, it is obtained by fusing in an iron vessel, animal matter, as dried blood, horn, hair, etc., with equal parts of carbonate of potassa; throwing the mass when cold, gradually into twelve or fifteen times its weight of water, and constantly stirring for half an hour; then filtering through linen, and adding to the clear solution, a mixture of two parts of alum and one of the sulphate of pro- toxide of iron, in solution. Carbonic acid is evolved with effervescence, and a blackish-brown precipitate is thrown down in abundance, which is 1092 Pharmacy. washed by means of a large quantity of water, every twelve hours. These washings last for nearly a month, and the precipitate changes successively to greenish-brown, bluish, and deep blue. It is then drained upon a cloth, divided into cubical masses and dried. As prepared in this manner, it is impure, and unfit for medicinal purposes. It always contains a portion of alumina, uncombined sesquioxide of iron, and ferro- cyanide of potassium. Pure Prussian Blue is of a rich deep blue color, tasteless, and insolu- ble in water and alcohol. Diluted acids do not act on it, but the strong acids decompose it, with a variety of phenomena. The alkalies also decompose it, forming ferrocyanates. At a red heat it takes fire, burn- ing slowly, and yielding sesquioxide of iron. When Prussian blue is boiled with diluted muriatic acid, filtered, and ammonia added to it, no precipitate takes place if the drug be pure—should one ensue however, the article is impure. Properties and Uses.—Prussian Blue is tonic, sedative, and febrifuge, and is much employed in febrile diseases, by Eclectics, in conjunction with sulphate of quinia ; it was introduced to the profession for this pur- pose, by Professor I. G. Jones, formerly one of my colleagues in the Eclectic Medical Institute, Cincinnati, who has used it with immense suc- cess, and who does not regard febrile or inflammatory symptoms in its administration, provided the disease be, in the least degree, of a peri- odica] character. It is now successfully used in intermittent, congestive, bilious, and typhoid fevers, especially during the remissions, and also in typhoid pneumonia; the dose is three or four grains, combined with the same quantity of sulphate of quinia, and which is to be repeated every three, four, or five hours, according to the nature of the case. Prussian blue, or as more commonly called among physicians, Prussiate of Iron, has likewise been successfully used in diarrhea, summer complaint of children, pertussis, dyspepsia, epilepsy, hysteria, chorea, and facial neuralgia. The dose is usually from one to five grains, three times a day. Ferri Iodidum. Iodide of Iron. Preparation. — Take of Iodine two ounces; Iron Filings one ounce; Distilled Water a pint and a half. Mix the Iodine with a pint of the Distilled Water, in a porcelain or glass vessel, and gradually add the Iron Filings, stirring constantly. Heat the mixture gently, until the liquid acquires alight greenish color; then filter, and after the liquid has passed, pour upon the filter he remainder of the Distilled Water boiling hot. When this has passed, evaporate the filtered liquor at a temperature not exceeding 212°, in an iron vessel, to dryness. Keep the dry Iodide in a closely stopped bottle.— U S. History.—In this process, iron is made to combine with iodine by means of water; when the iron is added to the liquid, it is at first red or orange-colored, but as soon as all the iodine has united with the iron by the application of heat, it changes to a greenish color, which is a solu- Ferrum. 1093 tion of the iodide of iron, and yields the salt by evaporation. The iodine unites Avith about half its weight of iron. In its preparation according to the above formula, the iron is rapidly oxidated at the expense of the water, the protoxide being formed; while the hydrogen of the water combines with the iodine to form hydriodic acid. The result is a solu- tion of hvdriodate of protoxide of iron, or, according to some chemists, a solution of protiodide of iron, which is believed to be the best prepa- ration for medicinal use. It is very difficult to procure this salt perfectly pure, on account of the tendency of the solution to absorb oxygen, which partly converts it into an iodide of the sesquioxide instead of the protox- ide of iron ; this action is nearly overcome by the evaporation to dryness being effected in an iron vessel. Iodide of iron has a crystalline or irregularly foliated texture, accord- ing to its method of preparation, is sometimes of a dark grayish-black metallic appearance, but, when made according to the above formula, is greenish-black, and has a strong styptic, chalybeate taste. When ex- posed to the air, it deliquesces rapidly, sesquioxide of iron separating. At a moderate heat it fuses, and becomes, on cooling, an iron-gray, opake, crystalline mass, having a metallic luster. If the heat be higher the protiodide parts with iodine in violet fumes, until the sesquioxide of iron alone remains. Iodide of Iron is very soluble in Water or Alcohol. If the solution be evaporated OA'er quicklime, with as little contact of air as possible, and without artificial heat, large, transparent, tabular crystals of a pale yellowish-green color may be obtained. The anhy- drous salt consists of one equivalent of Iodine 126.3, and one of iron 28=154.3. The crystallized salt contains in addition five equivalents of water 45=199.3. The formula of the anhydrous salt is Fe I, that of the crystallized Fe I+5HO. It is incompatible with alkalies and their carbonates, lime-water, and with all other substances by which sulphate of iron is decomposed. Its solution may be kept from decomposition, by placing in it a coil of iron wire. Properties and Uses.—Iodide of Iron is a tonic, alterative, diuretic and emmenagogue, and influences the system more like the ferruginous salts than those of iodine. It improves the appetite, invigorates the digestive organs, blackens the alvine evacuations with a diminution of their fetor. Sometimes it acts as a laxative, but more generally as a diuretic. It has been efficaciously used in scrofula, chlorosis, secondary syphilis, amenorrhea, chronic rheumatism, chronic cutaneous diseases, leucorrhea, asthenic dropsy, old visceral engorgements, atonic dyspepsia, and in all cases where there is torpor in the system of nutrition, where there is paucity of red globules in the blood, and the fluid is too thin. On account of its tendency to decomposition when exposed to the air, it should always be given in solution. (See Liquor Ferri Iodidi.) It has, however, been given in pill form, being protected from deleterious agencies by the use of honey and tragacanth. The Liquor Ferri 1094 Pharmacy. Iodidi, evaporated to a proper consistence for making pills, would proba- bly form a better mode of administering this salt in a solid state, than when made by the above process. (See Pilulos Ferri Iodidi.) The dose of Iodide of Iron is three grains, three times a day, gradually increased to eight or ten grains. Ferri Lactas. Lactate of Protoxide of Iron. Lactate of Iron. Preparation.—Take of Lactate of Lime twelve and a half ounces ; pure Crystallized Sulphate of Protoxide of Iron eight and a half ounces; Boil- ing Water, cold Distilled Water, of each, sixty two and a half ounces by weight; Lactic Acid a sufficient quantity. Dissolve the Lactate of Lime in the Boiling Water; also dissolve the Sulphate of Iron in the cold Distilled Water; then filter each of these solutions, mix them in a matrass, acidulate slightly with Lactic Acid, and heat in a salt-water bath, stirring frequently until the double decomposition is completed. Then filter to separate the Sulphate of Lime, which precipitates, and evaporate rapidly to one-half, either in an iron vessel, or in a porcelain capsule containing a few Turnings of Iron. Filter again, and set aside to crystallize; and having washed the Crystals of Lactate of Iron in a funnel with a little Alcohol, dry them on bibulous paper. History. — Lactic Acid, according to the experiments of Bernard and Barreswil, exists in a number of the secretions of the human body, and especially in the gastric juice; it has therefore been supposed by medical men, that as this acid in its action on the salts of iron taken into the stomach, may convert them into a lactate, this salt already formed might prove a valuable agent; hence the preparation of Lactate of Iron, introduced to the profession by Gelis and Cont6. When pure, lactate of iron is in very white, crystalline plates, nearly permanent in the air, sparingly soluble in water, and its solution quickly changing to yellow, from higher oxidation of the iron. It has an acid reaction, and a mild chalybeate taste, and dissolves in forty parts of boiling water. If the powder is yellowish or greenish-white it is impure. It is liable to adulteration, and on this account should always be purchased in crys- talline plates, and in no other form. The Lactate of Lime used in the above process, may be made as follows: Add to two pints of Skim-milk, diluted with twice its bulk of Water, and contained in an earthen pan, sixty-four drachms of Powdered Lactin, (sugar of milk,) and flfty-one drachms of Powdered Chalk. Allow the whole to ferment for eleven or twelve days, at a temperature of from 80° to 90°, supplying water as it evaporates. Transfer the liquor to a capsule, heat it gradually to boiling, and stir it constantly. Boil for a quarter of an hour to coagulate casein, allow the insoluble matters to subside, and strain the liquid through flannel. The clear liquid is a solution of Lactate of Lime—which may be concentrated to dryness. The casein of the milk, in this operation, acting as a ferment, converts Ferrum. 1095 the Lactin of the Milk, and the Lactin which has been added, into Lactic Acid. This result would not ensue, were it not for the addition of Chalk, which saturates the Lactic Acid as it becomes formed, and prevents it from uniting with the casein, whereby the power of the latter as a ferment would be destroyed. Properties and Uses.—Lactate of Iron is considered a valuable chaly- beate tonic. Its use effects a decided improvement in the appetite, and in chlorosis, and anemic conditions it has been found very efficacious. The dose is one or two grains, repeated at intervals and gradually in- creased. As much as twelve or even twenty grains have been given in the course of the day, with good results. It may be used in the form of lozenge, pill, or solution. The lozenge may be made of one grain of the Lactate to twelve of Sugar; the pill, of one grain to the same weight of Liquorice Root, and sufficient Honey. A syrup is made by rubbing Lactate of Iron a drachm, with White Sugar six ounces, until it is all in fine powder ; then dissolve the mixture quickly in Boiling Water, dis- tilled, six and a half fluidounces. Pour the solution into a matrass placed on a sand-bath, and add to it six and a half ounces of White Sugar, in small pieces. When the Sugar is dissoh^ed, filter, and as soon as cold, pour the syrup into bottles and keep them well closed. The syrup is of a light amber color, and contains about four grains of the salt to the fluidounce. The dose is from two to four fluidrachms. Ferri Oxidum Hydratum. Hydrated Sesquioxide of Iron. Hydrated Peroxide of Iron. Hydrated Oxide of Iron. Preparation.—Take of Sulphate of Iron four ounces ; Sulphuric Acid three fluidrachms and a half; Nitric Acid six fluidrachms, or a sufficient quantity; Solution of Ammonia a sufficient quantity; Water two pints. Dissolve the Sulphate of Iron in the Water, and, having added the Sul- phuric Acid, boil the solution ; then add the Nitric Acid in small por- tions, boiling the liquid for a minute or two after each addition, until the Acid ceases to produce a dark color. Filter the liquid, allow it to cool, and add Solution of Ammonia in excess, stirring the mixture briskly. Wash the precipitate with Water until the washings cease to yield a precipitate with Chloride of Barium, and keep it in close bottles with sufficient Water to cover it.— U S. History.—In the above process, the Sulphate of Protoxide of Iron is first converted into the tersulphate of the sesquioxide, the same as in the preparation of pure Prussian Blue ; the addition of ammonia in ex- cess, after this change has been effected, causes the sesquioxide just formed to be precipitated in the hydrated state, and which is freed from any adhering sulphate of ammonia, by the washings, repeated until the barytic salt no longer causes a precipitate. The preparation should then be kept under water in close bottles, as the most convenient method for U6e when required. 1096 Pharmacy. Hydrated Oxide of Iron, as prepared by the formula given, is a soft, moist, reddish-brown magma. When dried at a heat not exceeding 180°, and then pulverized, a reddish-brown powder is obtained, not influenced by the magnet, and which is the sesquioxide in the form of hydrate, containing about 18 per cent, of water, and which is soluble in muriatic acid Avithout effervescence. A red heat drives oft' the com- bined water, and it then becomes the anhydrous sesquioxide, which is not so readily soluble in acids, and having no antidotal effect becomes unfit for medical use. The hydrated oxide of iron consists of one equiv- alent of sesquioxide 80, and two of water 18=98, and is represented by the formula Fea O3 + 2HO. Properties and Uses.—This preparation, as with other Chalybeates, possesses tonic properties. But it is principally used in cases of poison- ing by arsenic, in Avhich it proves a valuable antidote. When this hydrated oxide of iron is placed into an aqueous solution of arsenic, it removes the arsenious acid so thoroughly, forming an insoluble substance, that even sulphureted hydrogen will not indicate the presence of the poison. This insoluble substance, formed by a transfer of oxygen from the oxide to the acid, is subarseniate of protoxide of iron. The hydrate should be used in the moist or pulpy state, and in doses of a tablespoon- ful to an adult, or a dessert spoonful to children, which must be repeated every five or ten minutes, until relief is obtained. Twelve times the amount of arsenic swallowed, should be given of this prepara- tion of iron, and as it is a harmless article, even more may be advanta- geously administered. Of course, the sooner it is given after the poison has been taken, the more prompt and efficacious will be its action. Amorphous hydrated oxide of iron, when long kept in water, becomes crystalline, loses half its water of crystallization, and is much less easily soluble in Aveak acids ; consequently, it is of some importance in cases of poisoning by arsenic, that it be recently made. It is recommended to remake it every six months from the old oxide, by dissolving it in muriatic acid, and re-precipitating it with ammonia. The dry hydrate rubbed up with water, is much less efficient than the moist. As a tonic, it may be employed in doses of from five to twenty grains. In relation to this uniformly successful antidote to poisoning by arsenious acid, Prof. W. Procter, Jr., has recently furnished a formula which is easily executed, and which furnishes a concentrated solution of the ter-sesquisulphate of iron of known strength, so that the operator can graduate the precise quantity of oxide by means of his measure glass. The formula, together with Prof. P.'s remarks are given entire : Take of Proto-sulphate of Iron, well crystallized, sixty-four ounces, Troy; Sulphuric Acid seven fluidounces ; Nitric Acid, sp. gr. 1.38, twelve fluid- ounces ; Water a sufficient quantity. Ferrum. 1097 Reduce the Sulphate of Iron to moderately fine powder in an iron mortar, mix together the Acids and five fluidounces of Water, put the mixture in a large porcelain capsule on the sand-bath or other regular source of heat, and add the poAvdered Sulphate, about tAvo ounces at a time, stirring after each addition, till the effervescence ceases, until all has been added, and the elimination of nitrous fumes has censed. In the absence of a porcelain capsule and sand-bath, the operator may use a gallon glass jar, supported in a vessel of Boiling Water ; in either case, the vessel should be large enough to allow for active effervescence, and it is hardly necessary to say that the operation should be performed under a chimney-hood, or in the open air, to avoid the noxious fumes of Nitrous Acid. The dense solution thus obtained should then be diluted with Water until it measures four and a half pints, (wine measure,) and then filtered through thick muslin. Solution of Ter-sulphate of Iron thus prepared, has a dark, reddish- brown color in quantity, the specific gravity of 1.587 at 60° F., but little if any odor, a powerful styptic taste, and mixes readily with Water, so as to form a solution with more color in proportion to its dilution than the strong liquid. Each fluidounce of this solution contains a fraction more than 120 grains of Sesquioxide ; each fluidrachm 15 grains, and each minim a quarter of a grain ; and as it is equally applicable for pre- paring the Oxide for chemical as for antidotal purposes, this correspond- ence of weights with measures gives great facility in calculating any precise quantity desired. It is this solution which I have proposed should be kept by every apothecary as the source of Hydrated Sesquioxide of Iron. Its strength is such that it requires about an equal measure of commercial solution of Ammonia (sp. gr. .940,) to decompose it. The apothecary who is suddenly called upon for the antidote will proceed in the following manner : Take of Solution of Ter-sulphate of Iron half a pint; Solution of Ammonia half a pint (or a sufficient quantity) ; Water a sufficient quan- tity. Pour the Solution of Iron into a half gallon jar, add two pints of Water, and then add the Ammonia, stirring constantly until in slight excess. This is known when, after displacing the air in the jar by bloAV- ing, it continues to smell slightly of Ammonia. The contents of the jar are then thrown on a piece of strong muslin, previously well moistened, and the liquid, holding in solution Sulphate of Ammonia, expressed from it as quickly as possible, until the Oxide remains in the cloth of a pasty consistence. The cloth is then opened on a dish, Water added and incor- porated with the Oxide by means of a spatula, and then again expressed. If the demand is urgent, the Oxide may be sent Avithout further wash- ing, if not urgent, the washing may be repeated twice more. It is then quickly removed by a spatula from the cloth to a quart mortar, and 1098 Pharmacy. Water mixed with it by trituration, until it measures a pint, when it should be poured into a wide-mouthed bottle, corked, and the following label attached, viz : HYDRATED SESQUIOXIDE OF IRON. (Ferri Oxidum Hydratnm U. S. Pharm.) Antidote to Arsenic. This preparation consists of Hydrated Sesquioxide of Iron and Water, iu such proportion that each tablespoonful contains thirty grains of the dry Oxide; and is intended to neutralize the poisonous effects of Arsenious Acid, or common White, Arsenic, when taken into the sto- mach. It is well to precede the administration of this antidote by an active emetic of Ipecacuanha or of Mustard, so that any undissolved arsenic may be thus mechanically removed, if possible. If, however, this has not been done before obtaining the antidote, no time should be lost in giving it. The patient should take a tablespoonful for a dose every five or ten minutes, but if vomiting should intervene, let a dose be given immediately after each attack, unless otherwise directed by the physician in attendance. When the poisoning has been caused by Arsenite of Potassa, (Fowl- er's Mineral Solution) Soda, or Ammonia, or by the Salts of Arsenic Acid, after giving the first dose add six tablespoonfuls of Vinegar to the contents of the bottle, and shake it a few minutes, until the acidity is neutralized, and then give it as above. When the Oxide is intended for other ferruginous preparations, as, for instance, Citrate of Iron, it should be washed by displacement on a cloth filter, till the washings cease to precipitate Chloride of Barium. The small amount of Sulphate of Ammonia remaining in the Oxide, when prepared hurriedly as above, is of no account in a case of poisoning. The detail in the above label is not objectionable, as it will be often of use even to the experienced physician, not to speak of the very many who have had little if any experience in poisoning cases, and will like- wise enable any person of ordinary ability to administer the antidote without loss of time. When it is so easy to be prepared for these occa- sions, every apothecary who has a proper regard for his reputation and duty, will provide the means above detailed, and be ever ready. Ferri Oxidum Nigrum. Black Oxide of Iron. Preparation.—Take of Sulphate of Iron six ounces; Sulphuric Acid (commercial) two fluidrachms and two fluid scruples; Pure Nitric Acid four fluidrachms and a half; Stronger Aqua Ammonia? four fluidrachms and a half; Boiling Water three pints (Imperial measure). Dissolve half the Sulphate in half the Boiling Water, and gradually add the Sul- phuric Acid; boil; add the Nitric Acid by degrees, boiling the liquid after each addition briskly for a feAv minutes. Dissolve the rest of the Sul- phate in the remainder of the Boiling Water; mix the two solutions thoroughly ; and immediately add the Ammonia in a full stream, briskly stirring the mixture at the same time. Collect the black powder on a calico filter; wash it with Water till the water is scarcely precipitated. Ferrum. 1099 by a solution of Nitrate of Baryta, and dry it at a temperature not exceeding 180°. History.—In the above process, the first half of the sulphate of iron, after its solution in the water and acidulation with sulphuric acid, becomes, on the addition of the nitric acid, changed into the tersulphate of the sesquioxide of iron. The sulphuric acid is added for the same purpose as mentioned under Ferri Ferrocyanuretum, which see. The remaining half of the sulphate, dissolved in the balance of the water, forms a solution of the sulphate of the protoxide of iron. On mixing these two solutions, a compound one is formed, of sulphate of protoxide and sulphate of sesquioxide of iron; ammonia added to this, precipitates simultaneously the protoxide and sesquioxide, which chemically com- bine and form the Black Oxide. The Black Oxide of Iron is of a dark grayish-black color, presenting a shining fracture, when a piece dried in mass is broken, is permanent in the air, and is strongly attracted by the magnet. It dissolves without effervescence in muriatic acid, from which it may be precipitated by ammonia. Heated in close \ressels it parts with water, undergoing no other change; but heated in open vessels, it absorbs oxygen, and soon passes entirely to the state of a brownish-red sesquioxide. It is com- posed of two equivalents of protoxide and one of sesquioxide of iron, and two of water, its formula being 2 Fe 0+Fe2 03+2 HO. The scales which are struck from red-hot iron by the blacksmith's hammer, the JEthiops Martis of the old Materia Medicas, consist of chemical combinations of the protoxide and sesquioxide of iron in vari- able proportions. They are prepared for medicinal use by washing them, freeing them from impurities by the magnet; triturating them, and separating the fine powder by the method directed for making pre- pared chalk. It is, however, inferior in medicinal virtue to the black oxide prepared as above. Properties and Uses.—This is a valuable chalybeate, possessing the advantages of uniformity of composition and unchangeableness when exposed to air and moisture. Its dose is from five to twenty grains, two or three times a day. Ferri Phosphas. Phosphate of Iron. Preparation.—Take of Sulphate of Iron five ounces; Phosphate of Soda six ounces; Water a gallon. Dissolve the Sulphate of Iron and Phosphate of Soda, each separately, in four pints of the Water; then mix the solutions, and set the mixture aside, that the powder may precipitate; lastly, having poured off the supernatant liquor, wash the Phosphate of Iron with hot water, and dry it with a gentle heat— U. S. History.—In the above process a double decomposition takes place, the sulphuric acid of the sulphate of iron is set free, and combines with 1100 Pharmacy. the soda, forming a solution of sulphate of soda; while at the same time, the phosphoric acid of the phosphate of soda, also being set free, unites with the protoxide of iron, forming a precipitate of phosphate of iron. Phosphate of Iron, when prepared from a perfect sulphate of the protoxide, is at first of a white color, but from absorption of oxygen, it soon becomes bluish-white. It is usually met with in the form of a powder, of a bright slate-color, insoluble in water, but soluble in dilute muriatic acid. Properties and Uses.—Phosphate of Iron is a valuable chalybeate tonic. It has been recommended as a remedy in cancer, to be used internally, and also applied to the diseased part; likewise to restore and invigorate the virile powers. Professor Z. Freeman prefers it, in many instances, to the prussiate of iron in febrile diseases, and has derived marked advantage from it in this class of maladies. The dose is from one to ten grains, three times a day. Dr. Routh has met with much success in some cases of anemia and debility, brought on by venereal or other excesses, over-study, and depressing diseases, by the use of a new preparation of Phosphate of Iron, which he has found better adapted for a speedy cure than other preparations of iron; it has likewise been of much benefit in cases of virile weakness from onanism, or other causes. It is prepared by add- ing as much phosphate of iron as the monobasic phosphoric acid in a boiling state would take up, and allowing it to cool. The proportions will be found nearly two of acid to one of the phosphate. The solution obtained is of a semitransparent, greenish or slaty hue, which hardens on exposure to the air for a day ; but mixed with liquorice powder or flour, it can be at once made up into pills. The compound is soluble in any pro- portion of water, and free from any nauseous, inky taste. It is not yet analyzed, to know whether it is a superphosphate of iron, or a mere solu- tion of the phosphate in the acid. It does not gripe or constipate, and has proved beneficial in cases of debility, where there is a prevalence of nervous symptoms, or a large quantity of phosphates voided by urine. Dose, one or two grains, three times a day—in some instances combined with an equal proportion of phosphate of quinia. Ferri Pulvis. Powder of Iron. Reduced Iron. Iron by Hydrogen. Preparation.—Take of Subcarbonate of Iron, previously calcined in an open vessel, two pounds and a half, or a convenient quantity. Into a wrought-iron reduction tube, of about four inches in diameter, introduce the Subcarbonate, contained in an incomplete sheet-iron tube, open at both ends, made by bending the iron into the form of a cylinder, and of such a size as to fill loosely about seven-eighths of the reduction- tube. Place the reduction-tube longitudinally in an oblong charcoal- fufnace; and, by means of a self-regulating generator of Hydrogen, Ferrum. 1101 pass through it a stream of that gas, previously purified by bubbling successively through solution of subacetate of lead, diluted with three times its volume of water, and through milk of lime, severally contained in half-gallon bottles, about one-third filled. Connect with the further extremity of the reduction-tube a lead tube bent so as to dip into water. Make all the junctions air-tight by appropriate lutes; and, when the Hydrogen has passed long enough to fill the whole of the apparatus to the exclusion of atmospheric air, light the fire and bring that part of the reduction-tube occupied by the Subcarbonate to a dull-red heat, which must be kept up so long as the bubbles of Hydrogen, breaking from the water covering the orifice of the lead tube, are smaller than those pass- ing through the milk of lime. When the reduction is completed, remove the fire, and allow the whole to cool to the ordinary temperature, keeping up, during the refrigeration, a moderate current of Hydrogen through the apparatus. Lastly, withdraw the reduced Iron from the reduction tube, detach it from the sheet-iron tube, and, having powdered it, keep it in well-stopped bottles. When two pounds and a half of Sub- carbonate of Iron are operated on, the process occupies from five to eight hours.—U. S. History.—This preparation is a fine powder of metallic iron, procured by reducing the sesquioxide of iron by hydrogen, at a dull-red heat. The subcarbonate of iron is calcined, which removes its water, and is then subjected to the reducing influence of hydrogen, purified in the manner named. The oxygen of the sesquioxide unites with the hydro- gen, forming water, and the iron is left in its metallic state. Much care is necessary in preparing this article. If the subcarbonate of iron has not been freed from sulphate of soda by thorough washings, a sulphuret of sodium will be formed, and the pulverized iron spoiled; if the heat be below dull redness, some of the oxide will escape reduction; if it exceed that point, the reduced iron will agglutinate and be difficult to powder. Souberain and Dublanc have given full directions for the manufacture of powder of iron, including the purifying of the hydrogen, the construction of the furnace, regulation of the heat, avoiding explo- sions, etc., and which may be found in the American Journal of Phar- macy, Vol. XVIII, page 303. Prof. Procter, in Vol. XIX, page 11 of the same journal, has made known some valuable improvements in their process. To both of which the manufacturer is referred. Powder of Iron, when fully deoxidized, is of an iron-gray color, and tasteless. When black it is imperfect, and should be rejected. Dilute acids cause Avith it an evolution of hydrogen with effervescence. Placed on an anvil and struck with a smooth hammer, a brilliant metallic scale is formed. It oxidizes rapidly, and hence should be kept in dry and well-closed bottles. Properties and Uses. — A valuable tonic, and is considered to be the best form of metallic iron for medicinal employment. It may be used 1102 Pharmacy. in chlorosis, anemia, and all diseases in which the coloring matter of the blood is deficient. The dose is from three to six grains, four or five times a day, and is best given in the form of pill. Ferri Sesquioxidum. Sesquioxide of Iron. Red Oxide of Iron. Preparation.—Expose Sulphate of Iron to heat, until the water of crystallization is expelled. Then roast it by an intense fire so long afe acid vapors arise. Wash the Sesquioxide until the washings, when examined by litmus, appear free from acid. Lastly, dry it on bibulous paper. History.—Sesquioxide of Iron is a reddish-brown, tasteless, insoluble powder, called Colcoihar. It is an anhydrous sesquioxide of iron, and is soluble in muriatic acid. Properties and Uses.—It possesses tonic and somewhat styptic proper- ties, and is used principally in strumous and neuralgic affections, in com- bination with extract of conium. The dose is from two to eight grains, three or four times a day. The Red or Styptic Powder is prepared by merely submitting sulphate of iron to a red-heat, and continuing it until a reddish substance is formed ; it undoubtedly contains a portion of acid. It is powerfully as- tringent and styptic, and is used as an application to bleeding piles, and external hemorrhages ; it is usually applied in the form of ointment, and may also be given internally for the same purposes. Ferri Subcarbonas. Subcarbonate of Iron. Precipitated Carbonate of Iron. Preparation.—Take of Sulphate of Iron eight ounces ; Carbonate of Soda nine ounces; Boiling Water a gallon. Dissolve the Sulphate of Iron, and Carbonate of Soda, each, separately, in four pints of the Water; then mix the solutions; and having stirred the mixture, set it by that the powder may subside. Lastly, having poured off the supernatant liquor, wash the Sub-carbonate of Iron with hot water, wrap it in bibu- lous paper, and dry it with a gentle heat.— U. S. History.—In the above process a double decomposition takes place; the sulphuric acid of the sulphate of iron unites with the soda forming a solution of sulphate of soda ; while the carbonic acid of the carbonate of soda, at the same time, unites with the iron, forming a precipitated hydrated carbonate of protoxide of iron. During the washing and drying, the precipitate absorbs oxygen and parts with nearly all its carbonic acid, and forms a sesquioxide of iron with a small portion of carbonic acid present. Hence the name, Subcarbonate of Iron, is given to it, to distinguish it from the sesquioxide, made by calcining sulphate of iron until all its acid is removed. If carbonate of potassa be used instead of soda, the sulphate of potassa formed will be found less solu- ble, and not so easily removed by washing. Ferrum. 1103 The powder of subcarbonate of iron, is of a reddish color, and has an unpleasant, slightly styptic taste ; it is insoluble in Avater, but readily soluble in muriatic acid, evolving carbonic acid with effervescence. Am- monia or potassa precipitates the sesquioxide of iron from its solution in muriatic acid, and when properly prepared, sulphureted hydrogen, or ferrocyanuret of potassium added to the supernatant liquor, should give no signs of the presence of any metal in solution. Subcarbonate of iron, is a hydrated sesquioxide, containing a small amount of protoxide and carbonic acid. It is incompatible with acids and acidulous salts. Properties and Uses.—Subcarbonate of iron is tonic, alterative, and emmenagogue. In large doses it may produce a sense of weight or fullness at the stomach, or a slight nausea, but no other unpleasant effects. The stools are colored black by its use. It is one of our best chaly- beates, and has been successfully used in neuralgia, especially Avhen connected with functional derangement of the stomach, chorea, chloro- sis, and those leucophlegmatic states of the system in which the blood is deficient in coloring matter. Sometimes used in intermittent fever, when connected Avith an anemic condition or where the nutritive functions are deranged. In chronic diarrhea and dysentery, enlargement of the liver and spleen, epilepsy, dropsy, cancer, scrofula, and diseases of the urinary organs, connected with debility, it has been successfully used. The dose is from five grains to two drachms, three times a day; no nicety need be observed in the dose. It is not so powerful an antidote in poisoning by arsenic, as the hydrated sesquioxide of iron in the form of magma, yet it should always be used, until the latter can be obtained. Off. Prep.—Tinctura Ferri Chloridi. Ferri Sulphas. Sulphate of Iron. Sulphate of Protoxide of Iron. Green Vitriol. Copperas. Preparation.—Take of Iron Wire, cut in pieces, twelve ounces ; Sul- phuric Acid eighteen ounces; Water one gallon. Mix the Sulphuric Acid and Water, and add the Iron Wire ; then heat the mixture until effer- vescence ceases. Pour off the solution, and having added half a drachm of Sulphuric Acid, filter through paper, allowing the lower end of the funnel to touch the bottom of the receiving vessel. Evaporate the filtered liquor in a matrass until sufficiently concentrated, then set it aside in a covered Aressel to crystallize. Drain the crystals in a funnel, dry them on bibulous paper, and keep them in closely stopped bottles.— U. S. History.—When concentrated sulphuric acid is in contact with iron, it does not readily act upon it; but if it be diluted with water, the oxygen of the water changes the iron into a protoxide; the sulphuric acid unites with this, forming a solution of sulphate of protoxide of iron, and hydrogen is set free. An excess of iron is advantageous, as it secures 1104 Pharmacy. a perfect sulphate. The addition of a small portion of sulphuric acid previous to filtering the solution, is for the purpose of holding in solution any sesquioxide that may have been formed, and thereby enabling the salt to crystallize on evaporation, entirely free from the sesquioxide ; and the direction to have the funnel come in contact with the bottom of the receiving vessel, is for the purpose of avoiding, as much as possible, the contact of air, which favors the conversion to sesquioxide. For the same reason, after concentration of the solution by evaporation, the vessel in which it crystallizes should be kept covered. Sulphate of iron is an efflorescent salt, forming transparent, pale bluish-green crystals, with the shape of oblique rhombic prisms. It possesses a strong acid, astringent taste, and an acid reaction. Exposed to the air, it absorbs oxygen, and becomes finally covered with an efflo- rescence of a yellow color, which is the insoluble subsulphate of the sesquioxide. When the salt is entirely green, or approaches green more than blue, it is an indication of the presence of some sesquioxide. It is soluble in water, but is insoluble in alcohol. Twice its weight of cold, and three-fourths its weight of boiling water are required to dissolve it, and the solution is bluish-green ; but it soon becomes green and then reddish, when exposed to the air, in consequence of the absorption of oxygen, which precipitates a small amount of sesquisulphate of the ses- quioxide of iron. A few drops of sulphuric acid added to the solution prevents, or greatly retards this change. Exposed to a moderate heat, it fuses in its water of crystallization, six-sevenths of Avhich passes off, leaving a grayish-white anhydrous salt. If the temperature be increased to a red heat, it parts with its acid, and is changed into the anhydrous sesquioxide of iron, called Colcothar. It is incompatible with the alkalies, and their carbonates, soaps, lime-water, the chlorides of barium and calcium, the borate and phosphate of soda, nitrate of silver, acetate and subacetate of lead, and astringent vegetable infusions ; with the latter of which, it forms with their tannic and gallic acids, a black substance of an inky nature. The impure commercial sulphate of iron is unfit for medicinal purposes. Crystallized sulphate of iron, consists of one equiv- alent of acid 4J, one of protoxide 36, and seven of water 63=139; its formula is Fe O+S 0; +7 HO. Copper and Zinc are sometimes present in sulphate of iron ; copper may be detected by dipping into the solution a bright, polished plate of iron, which becomes covered with a broAvn cupreous crust, deposited from the solution. If a solution of the salt be sesquioxidated by boiling with nitric acid, and the iron be precipitated by an excess of ammonia, and then filtered, it will be of a blue color if copper be present; but if zinc be present, the white oxide will separate in flakes, on apply- ing heat to the solution and boiling to drive off the ammonia. Pure sulphate of iron is precipitated from its solution by ferrocyanuret of potassium, of a white color, which in the impure kinds is more or less Ferrum. 1105 blue, according to the proportion of sesquioxide of iron which is present. Properties and Uses.—Sulphate of Iron is irritant, tonic, and astrin- gent. Nausea and vomiting, and gripings of the bowels, are apt to follow the administration of large doses; and the stomach is more or less injured by a long continued use of it. It has been used as a tonic in scrofula, dyspepsia, chlorosis, amenorrhea, and in debility following protracted diseases. In phthisis pulmonalis the following preparation has been found very serviceable ; it relieves cough, assists expectoration, improves the appetite and digestive functions, and invigorates the whole system:—Take of commercial sulphate of iron six drachms ; Whisky or good Holland Gin, half a pint; mix together. The dose is half a fluidrachm every two hours. As an astringent, sulphate of iron is given in diseases attended with immoderate discharges, as passive hemor- rhages, colliquative sweats, diabetes, chronic mucous catarrh, leucor- rhea, gleet, etc. The dose is from one to five grains in the form of pill. In an overdose, it acts as a poison. Externally, the solution is used in eruptions of the face, chronic ophthalmia, and gleet, of various strengths, from one or two, to eight or ten grains of the salt to the fluidounce of water. Off.

Ferri Sulphas Exsiccatum. Dried Sulphate of Iron. Preparation.—Expose any convenient quantity of Sulphate of Iron to a moderate heat, in a porcelain or earthenware vessel, not glazed with lead, till it is converted into a dry, grayish-white mass, which is to be reduced to powder. History.—By this process about six-sevenths of the water of crystal- lization of the sulphate of iron is expelled. If the heat used should exceed 400°, the salt would become decomposed, hence it must not extend beyond it. Properties and Uses.—Same as Sulphate of Iron; to be used in pill form. Three grains of the dried sulphate of iron are equivalent to five of the crystallized sulphate. Externally, in solution, as an astrin- gent lotion for indolent ulcers, and as an injection in leucorrhea, and gonorrhea of females. Off. Prep.—Lotio Hydrastis Composita ; Pilulae Polygoni Compositae. Ferri Sulphuretum. Sulphuret of Iron. Preparation.—The best Sulphuret of Iron is made by heating an iron rod to a full white-heat in a forge, applying a stick of sulphur to the end 70 1106 Pharmacy. of the rod, and alloAving the fused globules of Sulphuret which form to fall into a deep vessel filled with water. These should be freed of sulphur and kept in a close vessel. An inferior kind, but sufficiently good for pharmaceutic purposes, may be obtained by mixing thoroughly together, Sublimed Sulphur one part, and Iron Filings three parts. Heat the mixture in a covered cruci- ble till it becomes red-hot, then remove the crucible from the fire, still keeping it covered, and allow the action to go on without any further heat. History.—There are a number of Sulphurets of Iron, among the most important of which are the Proto-sulphuret, or Sulphuret of the protox- ide ; the Sesquisulphuret, or Sulphuret of the Sesquioxide, the Bisulphu- ret or Cubic Pyrites, and the Magnetic Pyrites, which consists of five equivalents of protosulphuret, and one of bisulphuret; this last dissolves in acids, yielding sulphureted hydrogen and a residue of sulphur. The protosulphuret, however, is the one more generally used in Pharmacy for the production of hydrosulphuric acid gas, (sulphureted hydrogen). When solid sulphur is applied to a rod of iron heated to a full white heat, the product is similar to magnetic pyrites; but Avhen the proto- sulphuret is obtained by heating Flowers of Sulphur with Iron Filings in excess, it always contains an excess of iron. In the first instance, when sulphur is applied to white-hot iron, the metal apparently becomes hotter, the two bodies combine with the emission of brilliant sparks, the protosulphuret is instantly formed, and falls down in a fused and incan- descent state, and on being received in the water, broAvnish-yellow glo- bules are obtained, having a somewhat crystalline texture. When pure, the officinal sulphuret of iron furnishes a yellow poAvder, and is easily dissolved in diluted sulphuric or muriatic acid, evolving sulphureted hydrogen, and not leaving a residue of sulphur. As ordinarily prepared, however, it is not completely soluble in diluted sulphuric acid, and leaves a residue of uncombined sulphur. Pure protosulphuret of iron consists of one equivalent of iron 28, and one of sulphur 16.12=44.12; its for- mula is Fe S. The fused globules have the composition of 5 Fe S+Fe S2, or according to some, 5 Fe S+Fe2 Si. Properties and Uses.—This preparation is employed in Pharmacy only for the production of hydrosulphuric acid gas, (sulphureted hydrogen). Diluted sulphuric or muriatic acid is added to it, in a proper vessel, and the sulphureted hydrogen is disengaged as a gas, and may be collected over warm water, or solution of salt. In this process water is decom- posed, and its hydrogen forms hydrosulphuric acid, by uniting Avith the sulphur, while the oxygen changes the iron into a protoxide, which com- bines with the sulphuric acid. Sulphureted Hydrogen is a transparent and colorless gas, having a very offensive and peculiar smell, similar to that of putrid eggs. When respired, even although much diluted with Ferrum. 1107 air, it is highly deleterious. It is combustible, burning with a bluish flame, and producing sulphurous acid gas and water. Its specific gravity is 1.178. Water absorbs two or three times its volume of the gas, and acquires its smell, and a nauseous sweetish taste; the action of the air upon the solution, gradually decomposes it, with the formation of water and deposit of sulphur. Hence, the solution should always be kept in small vials, quite full and closely stopped. Hydrosulphuric acid satu- rates bases, forming salts known as Hydrosulphates, Sulphohydrates, or Htfdrosulphurets. It consists of one equivalent of sulphur 16, and one of hydrogen 1=17 ; its formula is HS. The following has cured several cases of syphilis: Heat a piece of Steel to a welding heat, apply a roll of Sulphur to it, and let the drops fall in Cold Water. Pulverize these globules or drops, and add one table- spoonful to a pint of Whisky. Let the mixture macerate for a few days. The dose is a tablespoonful five or six times a day. Ferri Tannas. Tannate of Iron. Preparation.—Take of pure Tannic Acid nine ounces; Precipitated Subcarbonate of Iron forty-four ounces ; Water a sufficient quantity. Dis- solve the Tannic Acid in sufficient water, and boil the solution, to which, while boiling, add gradually the Subcarbonate of Iron, moderately dried ; agitate the solution till effervescence ceases. Evaporate the solution in a porcelain vessel, at a temperature of 176° F., until it becomes thick ; then spread it on glass or porcelain to dry in a stove at 95°. History.—Thus prepared, Tannate of Iron is in flat pieces, of a crim- son color, tasteless, and insoluble in water. Properties and Uses.—Tannate of Iron possesses tonic and astringent properties. It has been used with benefit in chlorosis, amenorrhea, chronic diarrhea, and in the diarrhea accompanying some febrile dis- eases, etc. The dose is two or three grains, made into pills, and gradually increased, so that in the course of a day thirty grains may be given. Ferri Valerianas. Valerianate of Iron. Preparation. —To clean Iron Filings, in a Wedgewood mortar, add gradually an equal weight of Valerianic Acid, and stir constantly. In an hour, add Distilled Water; gently warm the whole in a flask, and filter. The surface in contact with the air becomes covered over with a crystalline layer of the Valerianate; collect this, and expose as before, repeating the process as long as it continues to yield crystals. Or, it may be prepared by adding a cold solution of Valerianate of Soda to a solution of three parts of Sesquichloride of Iron in one hundred of Water. The solution of Valerianate of Soda, proper for the reaction, is made by saturating five parts of oily Valerianic Acid in sixty of Water with Carbonate of Soda, and then boiling the liquid to expel all the Carbonic 1108 Pharmacy. Acid. The precipitated Valerianate of Iron is washed with a little Cold Water, and dried at a temperature not exceeding 68°. The Dublin Pharmacopoeia of 1850, gives the following process for obtaining this salt: Take of Valerianate of Soda five ounces and three drachms, (Dublin weight); Sulphate of Iron four ounces, (avoirdupois); Distilled Water one pint, (Imperial measure). Convert the Sulphate of Iron into a tersulphate of the sesquioxide, (as directed in the formula for Prussian blue), and add Distilled Water until the solution be aug- mented to the bulk of eight fluidounces, (Imperial measure). Dissolve the Valerianate of Soda in ten fluidounces of the Water, and mix the two solutions cold; then, having placed the precipitate which forms, upon a filter, and washed it with the remainder of the Water, dry it, by wrapping it in bibulous paper, and allowing it to stand on a porous brick for some days. When dried, it should be kept in well stopped bottles. History. — In this latter process after having converted the sulphate of protoxide of iron into the tersulphate of sesquioxide, a double decom- position is effected between this latter salt and the valerianate of soda, in which sulphate of soda is formed, and remains in solution, while the tervalerianate of sesquioxide of iron is precipitated. Or, three equiva- lents of valerianate of soda, reacting on one of tersulphate of sesquiox- ide of iron, result in three equivalents of sulphate of soda, and one of tervalerianate of sesquioxide of iron. Valerianate of Iron is in the form of a loose, amorphous powder of a dark tile-red color, and having a slight taste and odor of valerianic acid. It is insoluble in cold water, soluble in alcohol, and is decomposed by boiling water, which removes its acid and leaves the sesquioxide of iron remaining. A fraudulent article is sometimes sold, consisting of tartrate or citrate of iron, to which oil of valerian has been added. It may be detected, by observing that the genuine salt gives oft' an odor of valeri- anic acid when treated with dilute muriatic acid. Properties and Uses.—Valerianate of Iron is a nervo-tonic, and will be found serviceable in nervous disorders, hysteria, chorea, neuralgia, chlorosis, and anemic conditions with excitability or irritability of the nervous system. The dose is one or two grains, in pill form, repeated three or four times a day. INFUSA. Infusions. Infusions are solutions of vegetable principles in water, effected with- out boiling, and to which, when not contra-indicated, some kinds of Spirit are occasionally added for the purpose of preserving them. The addi- tion of any Alcoholic mixture is, however, only made in cases Avhere the medicinal action of the liquor itself is desired. The almost universal method of preparing infusions is by pouring water on the vegetable Infusa. 1109 substances, previously cut or bruised, and macerating in a close vessel till cool. Sometimes a prolonged application of a low heat, by the side of a fire or otherwise, is required, for the purpose of extracting certain principles not so readily soluble by other means. When the active prin- ciple is volatile or impaired by heat, or when the vegetable contains a substance not readily soluble at a low temperature, and which it is re- quired to avoid in the infusion, Cold Water will be found preferable to Hot. Infusions form a very convenient mode of administering vegetable medicines, as the greater part of them are easily exhausted of their active principles in this way, without requiring to be very finely divided. The principal objection to them, is the difficulty of keeping them for any length of time, in consequence of which they require to be prepared extemporaneously, and in small quantities at a. time. Mr. Alsop, how- ever, states, that they may be preserved for months, by pouring them while boiling hot into bottles, up to the top, and forcing in corks of good quality. The water employed in making infusions should be pure, as fresh river, rain, or distilled water, instead of water from pumps, springs, or holding in solution saline principles. For the preparation of infusions, Mr. Alsop has introduced a mug or jar, having a perforated diaphragm about one-third way from the top of the pot, on which are placed the solid ingredients. The diaphragm is movable, and is supported on ledges placed on the inside of the vessel; it may be used to prepare infusions by Hot or Cold Water, or where digestion is required for some time. As the water in the jar becomes impregnated, the increased specific gravity it acquires causes it to descend, and its place is immediately supplied by fluid of less specific gravity, so that a continual circulation takes place until the whole of the soluble principles are extracted. In making infusions with Boiling Water, starch and other principles are often taken up, whose presence disposes to acidity or moldiness, or per- haps favors reactions which materially impair the infusions; on this account percolation by Cold Water is preferable, as it avoids these incon- veniences, beside which these infusions have a less tendency to decay than those made at a boiling temperature. The process of percolation or dis- placement by Cold Water, affords infusions of very great strength, and is preferred to any other mode ; it requires, however, that the articles should be more finely powdered, as a general thing, than is customary in preparing infusions in the ordinary way. When of too much strength, the infusion may be reduced by dilution with water. The usual rule for preparing infusions is, to add from half an ounce to an ounce of the coarsely bruised herb or root to a pint of water, of which, when prepared, the dose is from one to two fluidounces. They are better when prepared in glazed earthenAvare or porcelain vessels fitted with covers, than when prepared in metallic vessels, on account of a liability to chemical alteration from metallic influence, and which frequently impairs the preparation. Infusions containing acids, 1110 Pharmacy. or saline substances should always be prepared and kept in glass or china vessels. In the preparation of infusions, the reactions of agents should always be kept in view. Thus — Infusion of Chamomile flowers yields pre- cipitates with nitrate of silver, sulphate of iron, gelatin, yellow Peru- vian bark, tincture of chloride of iron, corrosive sublimate, and the acetates of lead. Infusion of horse-radish becomes turbid from depo- sition of vegetable albumen, and speedily runs into the putrefactive fermentation in warm weather. It likewise gives precipitates with infu- sions of galls, and Peruvian bark, with nitrate of silver, corrosive subli- mate, and the alkaline carbonates. Infusion of cloves affords precipitates, with the soluble salts of antimony, iron, lead, silver, and zinc, and also with lime-water. Infusion of Cascarilla, yields precipitates with acetate and subacetate of lead, sulphate of iron, sulphate of zinc, lime-water, nitrate of silver, acetates of lead, and infusion of galls. Infusion of Yellow Peruvian bark is incompatible with the alkalies, alkaline earths, vegetable astringents, tartaric acid, oxalic acid, and the soluble tartrates and oxalates. It also affords precipitates with other agents, which, however, do not always injure its efficacy or active principle, as corro- sive sublimate, arsenious acid, tartar emetic, gelatinous solutions, soluble salts of iron, silver, and zinc, and many vegetable solutions, as those of cloves, chamomile, columbo, cascarilla, galls, horse-radish, catechu, digitalis, senna, orange peel, rhubarb, valerian, and simaruba. Infusion of Colombo is best prepared by exhausting with cold water, which leaves the starch behind, and then heating the infusion to the boiling point in order to coagulate the albumen, and strain. Infusion of digitalis affords precipitates with the acetate of lead, sulphate of iron, and infusion of Peruvian bark, etc. As nearly all vegetable medicines are occasionally administered in the form of infusion, it would be useless to enter into an especial relation of them, further than already explained in the above general rules; they are more commonly prescribed as secondary 04' auxiliary measures, and are left for the nurse or family to prepare. However, there are a few compound infusions, some of which are of a spirituous nature, which it may be advisable to describe on account of their extensiA*e employment, and superior efficacy in the diseases for which they are recommended. Infusum Apii Compositum. Compound Infusion of Parsley. Preparation.—Take of Parsley Roots and Seeds, coarsely bruised, Subcarbonate of Iron, each, four ounces; Horse-radish Root, in small pieces, two ounces; Juniper Berries, Squill, White Mustard-seed, Man- drake Root, and Queen of the Meadow, of each, finely bruised, one ounce; Good Cider six quarts. Boil the Cider and pour it on the rest of the articles mixed together, in an earthen vessel; cover the vessel, and digest with a gentle heat for twenty-four hours. Infusum. 1111 The cider should not be hard, nor too new, but sparkling and pleasantly tart, and after digestion by heat, it should be allowed to remain upon the articles, without straining it off. By this course, the liquid becomes still further impregnated with the properties of the medicines. Properties and Uses.—This is a most excellent preparation in several varieties of dropsy, for which alone it is used ; it increases the action of the kidneys, regulates the bowels, improves the digestive functions, and promotes activity of the absorbent vessels. The dose is one or two fluidounces, three times a day. In the summer season, half the above quantity may be made at one time, as, otherwise, it becomes very sour and moldy. It should always be used immediately after its prepara- tion.—J. K. Infusum Epig^e,e Compositum. Compound Infusion of Trailing Arbu- tus. Diuretic Compound. Preparation.—Take of Trailing Arbutus, Queen of the Meadow Root, Dwarf Elder Bark, Marsh-mallow Root, each, coarsely bruised, half an ounce ; Boiling Water, good Holland Gin, of each, one pint; Honey a, sufficient quantity. Pour the Boiling Water and Gin, on the plants, and digest them with gentle heat, in a close covered vessel, for six hours; then remove from the fire, strain, and add sufficient Honey to render it pleasantly sweet. Properties and Uses.—This is a very valuable remedy in gravel, sup- pression of urine, high colored or scalding urine, inflammation of the urethra, and other disorders of the urinary organs. In oxalic deposits, however, it is of no utility. The dose is about two fluidounces, three or four times a day; in severe cases, this dose may be given every hour until relief is obtained, after which every three or four hours. In cases of gravel, a corresponding quantity of Wild Carrot Root and Seed may be advantageously added to the articles.—J. K. Infusum Geranii Compositum. Compound Infusion of Cranesbill. Preparation.—Take of Cranesbill, Witch Hazel, Black Cohosh, and Golden Seal, each, coarsely bruised, half an ounce; Boiling Water two pints. Mix the articles together, and digest with a gentle heat, in a close vessel, for two hours; remove from the fire, and strain. If required, alum one drachm, may be added. Properties and Uses.—This forms an efficacious astringent wash in aphthous and other diseases of the mouth and throat, when unaccom- panied with inflammation ; and is also useful as an injection in leucor- rhea, prolapsus ani, and prolapsus uteri.—J. K. Infusum Hydrastis Compositum. Compound Infusion of Golden Seal. Preparation.—Take of Golden Seal, Blue Cohosh, Witch Hazel, of each 'in powder, half an ounce; Boiling Water one pint; pulverized Alum one drachm; Honey a sufficient quantity. Add the plants to the Boiling Water, and digest with a gentle heat, in a close vessel, for half an hour, 1112 Pharmacy. remove from the fire, strain, add the Alum, and sufficient Honey to thoroughly sweeten the infusion. Properties and Uses.—This infusion is very valuable as a wash or gargle in various forms of sore mouth, and ulcerated sore throat.—J. K. Infusum Salvia Compositum. Compound Infusion of Sage. Preparation.—Take of Sage Leaves, Hyssop Leaves, of each, one ounce; Boiling Water two pints; pulverized Borax one drachm. Place the Herbs in the Boiling Water, allow them to digest for half an hour, then strain and add the Borax. Properties and Uses.—This infusion is employed as a wash and gargle in aphthae, sore throat, and quinsy, when accompanied Avith inflam- mation. LINIMENTA. Liniments. These preparations are designed for external application, and should always be of a consistence which will enable them to be applied to the skin by gentle friction with the naked hand, or flannel. They are usu- ally composed of Oily, Spirituous, Gummy, or Saponaceous substances, are thinner than ointments, more consistent than water, and at the temperature of the body are always liquid. The benefit derived from them, depends either upon their counter-irritating influences, or from absorption of their active constituents. Liniments are usually prescribed extemporaneously by physicians, each having a preference ; yet it is absolutely necessary that there be some established rule in relation to them, and that the officinal preparation be generally known. Linimentum Aconiti. Linimentum Aconiti Radicis. Aconite Liniment. Preparation.—Take of Aconite Root, in powder, four ounces; Glycerin two fluidrachms; Alcohol a sufficient quantity. Macerate the Aconite with half a pint of Alcohol for twenty-four hours, then pack it in a small displacer, and add Alcohol gradually until a pint of tincture has passed. Distil off twelve fluidounces, and evaporate the residue until it measures twelve fluidrachms. To this add Alcohol two fluidrachms, and the Glycerin, and mix them. History.—This preparation is offered by W. Procter, Jr., as a substi- tute for aconitia as an external anaesthetic application. It is tAvice the strength of the root, and is exceedingly active. The Glycerin is added for the purpose of retarding evaporation after application of the liniment to the skin, and which may be further secured by using oiled silk. Properties and Uses.—This liniment may be used in all cases in which aconitia would prove useful,, as in gout, neuralgia, and rheumatism. It is to be used as follows : Cut a piece of lint or muslin of the size and form of the part to be treated, lay it on a plate or Avaiter, and by means Linimenta. 1113 of a camel's hair brush, saturate it with the liniment. Thus prepared it should be applied to the surface, a piece of oiled silk laid over and kept in place by an adhesive edge, or by a bandage. Care should be taken not to apply it to an abraded surface, and in its use the patient should he informed of its character, and avoid bringing it in contact with the eyes, nostrils, or lips. Linimentum ^Eruginis. Mel yEgypticum. Verdigris Liniment. Preparation.—Take of Verdigris (Subacetate of Copper), in powder, one ounce; Vinegar seven fluidounces ; Honey fourteen ounces. Dissolve the Verdigris in the Vinegar, and strain through linen; then gradually add the Honey, and boil down to the proper consistence. Properties and Uses.—This is an external stimulant and escharotic, and is sometimes employed to repress or destroy fungous growths. It may be used undiluted or rubbed up with some unirritable ointment, in which latter state it forms an excellent stimulant to indolent ulcers. When diluted Avith water it has been applied to venereal ulcers in the mouth and throat, by means of a camel's hair brush, or used as a gargle.— U. S. Linimentum Ammonite. Liniment of Ammonia. Common or Volatile Liniment. Preparation.—Take of Solution of Ammonia a fluidounce; Olive Oil two fluidounces. Mix them.— U. S. History.—In this liniment a soap is formed by the union of the oil and ammonia, which is but imperfectly dissolved, and a white, opake emul- sion is obtained. Properties and Uses.—This preparation is used as a rubefacient in rheumatic pains, inflammatory diseases of the throat, and catarrhal and other pectoral affections of children. The skin is to be gently rubbed with it, or it may be applied over the part on a piece of flannel mois- tened with it. If it becomes too active, it must be diluted with a suffi- cient quantity of oil. Linimentum Ammonite Compositum. Compound Liniment of Am- monia. Preparation.—Take of Stronger Solution of Ammonia five fluidounces ; Tincture of Camphor two fluidounces; Spirit of Rosemary one fluidounce. Mix them well together. This liniment may also be made weaker for some purposes with three fluidounces of Tincture of Camphor, and two of Spirit of Rosemary. History.—This liniment of the two strengths given, is a mere dilution of the stronger Solution of Ammonia, in two different degrees; the ammonia itself being too poAverful for use. It closely resembles Gran- ville's Counter-irritant Lotion. The camphor and rosemary serve but little other purpose here than that of diluting agents. 1114 Pharmacy. Properties and Uses. — These liniments act promptly and powerfully, and may be employed as rubefacients, vesicatories, or escharotics. For mere rubefaction the weaker preparation may be used, and even for vesication; but where immediate action is desired, the stronger one must be employed. In applying them, a piece of linen folded two or three times, is saturated Avith the fluid, applied over the part, and prevented from evaporating by dry cloths placed over it; the degree of action depends entirely on the length of time in which it is thus kept in contact with the skin. A very good plan is to select a box the size of the part to be acted upon, introduce patent lint, saturated with the fluid, into the box, and hold it firmly upon the part. In from one to five or eight minutes, rubefaction is produced; in from three to eight or ten, vesi- cation ; and somewhat longer for its escharotic effect. It is usually employed in neuralgic, gouty, spasmodic, rheumatic, and other affections, where.speedy and powerful counter-irritation is demanded. Linimentum Cajuputi Compositum. Compound Cajeput Liniment. Preparation,—Take of Oils of Sassafras, Cajeput, and Hemlock, each, one ounce; Soap a sufficient quantity. Mix them together and form a liniment. Properties and Uses.—This forms a valuable stimulating and discu- tient application ; it is principally used in indolent scrofulous tumors.— J. K. Linimentum Calcis. Liniment of Lime. Preparation. — Take of Lime-Water, Linseed Oil, each, a fluidounce. Mix them together and form a liniment. History.—The Oil and Lime unite and form a Soap; and the oil being in excess separates upon standing. This is also called Carron Oil. Properties and Uses.—This is a very useful application to recent burns and scalds ; it is best applied on carded cotton. The following is also reputed beneficial in burns ; take of Lime-Water two fluidounces ; Oil of Turpentine, Olive Oil, each, one fluidounce. Mix. If to be used imme- diately after the accident, add Oil of Pennyroyal one fluidounce. Linimentum Camphors. Camphor Liniment. Preparation.—Take of Camphor an ounce and a half; Chloroform two fluidrachms; Olive Oil two fluidounces. Dissolve the Camphor in the Oil and Chloroform mixed together. Properties and Uses.—This forms an anodyne application in sprains, bruises, rheumatic and neuralgic pains, as well as other local pains. Linimentum Caoutchouc Caoutchouc Liniment. Preparation.—Take of Caoutchouc, in fine pieces, a convenient quan- tity; Oil of Origanum a sufficient quantity. Dissolve the Caoutchouc in the Oil. History.—In this manner Caoutchouc may be dissolved in any of the stimulating essential oils. If the mixture be spread on paper, allowed Linimenta. 1115 tc dry, and again spread, a valuable stimulating plaster may be had. A stimulating liniment was at one time much used by a certain class of practitioners, prepared as follows : Take of Caoutchouc, in small pieces, four ounces; Linseed Oil one pint. Mix together, and dissolve the Caoutchouc by means of a charcoal fire ; then add Tallow three-fourths of a pound; Antispasmodic Tincture, Oil of Spearmint, of each, two fluid- ounces ; Oils of Peppermint and Pennyroyal, of each, one fluidounce. This may be applied with much friction, or spread on a bladder. Properties and Uses. — These preparations may be used Avhenever stimulating applications are desired. We give them here, because they are sometimes employed by physicians of various schools. Probably, the addition of the Caoutchouc increases the non-conducting properties of these liniments. Linimentum Capsici Compositum. Compound Capsicum Liniment. Preparation.—Take of Tincture of Capsicum two fluidounces ; Tincture of Opium, and Aqua Ammoniae, of each, three fluidrachms ; Oil of Ori- ganum, two fluidrachms ; Oil of Cinnamon, and Tincture of Camphor, of each, one fluidrachm. Mix. Properties and Uses. — This is a very efficacious application in rheu- matic, pleuritic, neuralgic, and other pains. Linimentum Crotonis. Croton Oil Liniment. Preparation.—Take of Croton Oil one fluidounce ; Oil of Turpentine seven fluidounces. Mix together with agitation. Properties and Uses. — This acts as a prompt rubefacient; and when used for some time, produces pustulation. From ten to thirty minims may be placed upon a limited surface, and rubbed in ; and when pustu- lation is required, this should be repeated two or more times every day. Linimentum Nigrum. Black Liniment. Preparation.—Take of Olive Oil one ounce and a half; Sulphuric Acid one fluidrachm; mix well together, and then add, Oil of Turpentine half an ounce. Properties and Uses. — An active counter-irritant, but does not vesi- cate. To be rubbed on the part with a piece of lint, twice a day, until the skin becomes tender and inflamed. It may be used in indolent swellings of joints, rheumatic pains, and wherever active counter-irrita- tion is indicated.—Brodie. Linimentum Olei. Liniment of Oils. Preparation.—Take of Oils of Cedar, Cajeput, Cloves, and Sassafras, of each, one fluidounce. Mix. Properties and Uses. — This forms an efficacious application to rheu- matic and other painful affections ; it should be rubbed on the affected part, three or four times daily. 1116 Pharmacy. Linimentum Olei Compositum. Compound Liniment of Oils. Con- centrated Liniment. Preparation.—Take of Oils of Origanum, Hemlock, and Cajeput, and Camphor, each,/crar ounces, by weight; Capsicum two ounces. Mix the Oils and dissolve the Camphor in the mixture; then add the Capsicum, and let it macerate for fourteen days, frequently agitating. Then filter. Properties and Uses.—This is a powerful counter-irritant, and may be employed Avith advantage in indolent tumors, indurated mammae, rheu- matic and other pains, and to the spine, in epilepsy, nervous debility, etc.—J. K. Linimentum Opii. Liniment of Opium. Anodyne Liniment. Preparation.—Take of Castile Soap six ounces; Opium an ounce and a half; Camphor three ounces; Oil of Rosemary six fluidrachms ; Rectified Spirit two pints. Macerate the Soap and Opium in the Spirit for three days; filter, add the Oil and Camphor, and agitate briskly. Properties and Uses.—This is an anodyne and mild rubefacient appli- cation in sprains, bruises, rheumatic, and gouty pains. Linimentum Saponis Camphoratum. Camphorated Soap Liniment. Opodeldoc. Preparation.—Take of Common White Soap two ounces; Camphor one ounce; Oil of Rosemary three drachms; Oil of Origanum two drachms; Aqua Ammonia F F F, one ounce ; Alcohol one pint and a half. Digest the Soap with the Alcohol, by means of a sand-bath, till it is dissolved; then add the Camphor, Oils, and Ammonia, and when they are dissolved, pour the liquor into broad-mouthed bottles. This liniment has, when cold, the consistence of a soft ointment. History.—This Liniment is prepared with White Soap, which is made with animal fat, while Castile Soap is made with Olive Oil, in conse- quence of which, Avhen the Alcoholic solution cools, the liniment assumes an appearance of solidity. Under the name of Opodeldoc it is placed into wide-mouthed glass vials, holding about four ounces each, and is extensively employed throughout the country. It forms a soft, trans- lucent, uniform, yellowish-white mass, which melts at the temperature of the body. The formula above given, I consider to be much preferable to the one ordinarily followed in manufacturing the article. Properties and Uses. — Camphorated Soap Liniment is an excellent anodyne embrocation in sprains, bruises, rheumatic and other pains. Linimentum Stillingiae Compositum. Compound Liniment of Stil- lingia. Preparation.—Take of Oil of Stillingia one fluidounce; Oil of Cajeput half a fluidounce ; Oil of Lobelia two fluidrachms ; Alcohol two fluidounces. Mix together.—R. S. N. LlNIMENTA. 1117 Properties and Uses.—This forms a peculiar kind of Liniment, pos- sessing stimulant and relaxant properties. It is used in chronic asthma, croup, epilepsy, chorea, etc. In asthma and croup, the throat, chest and neck is to be bathed with it, three or four times a day. In chorea, epilepsy, and spasmodic diseases, the whole vertebral column is to be bathed with it. In rheumatism, sprains, and painful affections, the diseased parts are to be bathed with it. In asthma its action is very prompt and effectual, relieving and ultimately curing the most obstinate cases. In the majority of instances, when applied to the chest, neck, etc., the patient experiences a peculiar taste in the mouth, somewhat resembling that of the Lobelia and Stillingia combined. It is often used of less strength, as — Take of Oil of Stillingia half a fluidounce; Oil of Cajeput half a fluidounce ; Oil of Lobelia one fluidrachm ; Alcohol three fluidounces. Mix. It is an agent peculiar to Eclectic practice, and is very active and efficacious. Linimentum Succini Compositum. Compound Liniment of Oil of Amber. Preparation.—Take of Oil of Stillingia, Rectified Oil of Amber, each, one fluidounce; Oil of Lobelia three fluidrachms; Olive Oil two fluid- ounces. Mix together. Properties and Uses.—I have found this preparation very efficient in chronic asthma, croup, pertussis, chorea, epilepsy, rheumatism, sciatica, and various other spasmodic and painful affections ; in many instances being much superior to the Compound Liniment of Stillingia. Its man- ner of application is the same as recommended for the preceding Lini- ment. In very severe cases, it may be applied every hour, or half hour, and continued until vomiting ensues. It acts as a stimulant, relaxant, and antispasmodic. In many of the above diseases it will effect a cure without the exhibition of any internal medicine; and is especially useful among children to whom it is difficult to administer remedies by mouth, or in cases where the stomach rejects all medicines. Care must be taken not to use too much of this liniment at any one application.—J. K. Linimentum Terebinthinae Compositum. Compound Liniment of Turpentine. White Liniment. Preparation.—Take of Rose Water two and a half fluidounces; Yelk of Egg one; Oil of Turpentine three fluidounces; Oil of Lemon half a fluidrachm; Pyroligneous Acid, (or in its absence, Acetic Acid) one fluidounce. To the Yelk slowly add the Rose Water, and rub together in a mortar ; then add the Turpentine and Oil of Lemon. Pour the mixture into a pint bottle, and agitate to mix thoroughly ; then add the Acid, and agitate quickly and briskly. It must be kept well corked. Properties and Uses.—Used in asthma and inflammation of the lungs, rubbino- it on the throat and chest with a sponge or cloth, from the epi- glottic region to the epigastric; also useful wherever a counter-irritant is required. 1118 Pharmacy. LIQUORES. Liquors, or Solutions. Liquor Ferri Iobidi. Solution of Iodide of Iron. Preparation. — Take of Iodine two ounces ; Iron Filings an ounce; Powdered Sugar twelve ounces; Distilled Water a sufficient quantity. Mix the Iodine with five fluidounces of Distilled Water, in a porcelain or glass vessel, and gradually add the Iron Filings, stirring constantly. Heat the mixture gently until all the Iodine is dissolved, or until the liquid acquires a light-greenish tint. Then filter the solution into a glass bottle, containing the Sugar, and, after it has passed, pour Distilled Water gradually upon the filter, until the filtered liquor, including the Sugar, measures twenty fluidounces. Lastly, shake the bottle until the Sugar is dissolved, and keep it closely stopped.— U S. History.—By this process, the Solution of Iodide of Iron, is preserved from change by the addition of sugar. The iodine used should be dry, otherwise, less of the iodide will be formed, and the solution will be weaker. An excess of iron is employed, in order to prevent the absorp- tion of oxygen while filtering, from producing any change, previous to the contact of the liquor with the sugar. When all the iodine is con- verted into iodide of iron, the solution will contain seven grains and a half of the dry iodide to every fluidrachm. In forming the solution, the iron is rapidly oxidated at the expense of the water, the hydrogen of which unites with the iodine to form hydrio- dic acid. This unites with the iron forming a hydriodate of protoxide of iron, or, according to some chemists, a solution of protiodide of iron. This solution, however, as with all solutions in which iron is united with one equivalent of oxygen or chlorine, is exceedingly subject to decom- position by exposure to air and light, in which the oxide of iron passes into a sesquioxide, forming a solution of the hydriodate of sesquioxide of iron. To obviate this tendency to sesquioxidation, M. Frederking of Riga, and Professor Procter of Philadelphia, proposed the addition of saccharine matter, which they found to exert a protective action, and which fact has since been amply confirmed by many eminent chemists. Hence, the sugar is added to protect the solution of iodide of protoxide of iron from becoming converted into one of the sesquioxide. Solution of Iodide of Iron is of a transparent, pale-green color, nearly, if not quite, destitute of any sediment. If the addition of starch changes it to a blue color, it is not perfect, but holds free iodine. Sul- phuric acid added to it changes it to a brown color, with evolution of violent vapors on being heated. Properties and Uses.—The medical properties are the same as men- tioned under the head of Iodide of Iron; the dose is from twenty to forty drops, three times a day. It should be well diluted with water, LlQUORES. 1119 and the mouth should be carefully washed after each dose, in order to protect the teeth. Liquor Ferri Nitratis. Solution of Nitrate of Iron. Solution of Pernitrate of Iron. Solution of Ternitrate of Sesquioxide of Iron. Preparation.—Take of Iron Wire, cut in pieces, an ounce; Nitric Acid, (sp. gr. 1.42) three fluidounces ; Distilled Water a sufficient quan- tity. Mix the Acid with a pint of Distilled Water, add the Iron, and agitate occasionally until gas ceases to be disengaged ; then filter the solution, and add to it sufficient Distilled Water to make it measure thirty fluidounces.— U. S. History.—This preparation was introduced to the profession by Mr. William Kerr, of Scotland, in 1832. It is a very astringent liquid, of a transparent red color, and is apt to become turbid on standing, and to deposit sesquioxide. The tendency to this change was obviated by Mr. Kerr, by adding a small portion of muriatic acid to it. It is also pro- posed to add sugar to the solution for the same purpose. The salt, Ter- nitrate of Sesquioxide of Iron, is in crystals having the form of oblique rhombic prisms, colorless, or of a delicate lavender color, somewhat deli- quescent, soluble in water, not fully soluble in nitric acid, and consists of three equivalents of nitric acid 162.76, one of sesquioxide of iron 80.03, and one of water 9=251.79. On account of the great liability to change in this preparation, various suggestions have been made for the purpose of procuring a permanent solution ; among them is the following, offered, by W. Procter, Jr., of Philadelphia : Take of Iron Wire (card-teeth) cut in pieces, an ounce; Nitric Acid, (sp. gr. 1.42) three fluidounces ; Water thirteen fluidounces; Sugar, in powder, two pounds. Put the Iron in a thin wide-mouthed bottle, which should be kept cool by standing in cold"water, and pour upon it three fluidounces of Water. Then mix the Acid with ten fluid- ounces of Water, and add the mixture in portions of half a fluidounce to the Iron, agitating frequently until the Acid is saturated, using litmus paper to determine the saturation. When all the Acid has been com- bined, filter the solution into a bottle containing the Sugar and marked to contain thirty fluidounces. If the whole does not measure that bulk, pour Water on the filter until it does. When all the Sugar is dissolved, strain, if necessary, and introduce the syrup into suitable vials and seal them. This forms a syrup of the iVofonitrate of Iron. Mr. Joseph Laidley, of Richmond, Va., has ascertained the formation of Oxalic Acid in the syrup of the Sesqumitrate of Iron, and considers it an un- scientific and ineligible preparation ; for, without an excess of Acid, it is a mixture of proto and pernitrate, and with that excess the Acid gene- rates Oxalic Acid. He has found the solution of the protonitrate, as given by Prof. Procter, to keep perfectly well, even without the addition of the sugar, which, as the iron salt is already per oxidized, he considers 1120 Pharmacy. of no use for preventing what would not occur, viz : the further absorp- tion of oxygen from the atmosphere. Properties and Uses.—Solution of Nitrate of Iron is tonic and astrin- gent, and has been used successfully in chronic mucous diarrhea not attended Avith ulceration of the intestines, and in weak, nervous constitu- tions, where there are no existing indications of inflammation. It has been effectually employed in menorrhagia; and in leucorrhea it may be administered both internally and by injection. In the colliquative diar- rhea of tubercular phthisis it has afforded much benefit, as well as in chronic diarrhea and cholera infantum of anemic or scrofulous patients. The dose is seven or eight drops, sufficiently diluted, which may be repeated three or four times a day, and gradually increased to twenty or twenty-five drops. When used as an injection into the vagina, it should be diluted sufficiently to occasion only a slight heat and smarting. W. W. D. Livermore offers the following formula for the preparation of a permanent solution of this ferruginous salt; it furnishes nearly the same result as obtained by Procter's method given above : Take of Sul- phate of Iron eight ounces ; Carbonate of Soda ten ounces; White Sugar twenty ounces; Nitric Acid, (sp. gr. 1.42) five fluidounces and five fluidrachms ; Boiling Water, Simple Syrup, of each, a sufficient quantity. Dissolve the Sulphate of Iron and Carbonate of Soda, each, in tAvo pints of the Water, filter, and add to each solution two ounces of Simple Syrup. Mix the solutions, and allow the precipitate to subside. Pour off the supernatant liquid, and wash the precipitated carbonate carefully with Sweetened Water, until the washings have no longer a saline taste. Collect the Precipitate upon a fine muslin strainer, and with gentle pres- sure express as much of the Water as possible. Transfer to a porcelain capsale, and add gradually the Nitric Acid, previously diluted with an equal measure of Water. Mix the Sugar with the solution, and dissolve over a water-bath, stirring from time to time with a glass rod. When done, the syrup should be made to measure thirty fluidounces, by the addition of a sufficient quantity of Water. Each fluidrachm of this syrup contains ten grains of Dry Nitrate of Iron, and the dose varies from twenty to forty drops. Liquor Iodini Compositus. Compound Solution of Iodine. Preparation.—Take of Iodine six drachms ; Iodide of Potassium an ounce and a half; Distilled Water a pint. Dissolve the Iodine and the Iodide of Potassium in the Water.— U. S. History.—Iodine is but sparingly soluble in water, but dissolves freely in a solution of Iodide of Potassium. In preparing this solution two parts of the iodide are generally added with one of iodine, forming a concentrated solution of iodine, which is the active medicinal agent in the solution. The solution loses its strength by exposure to the air, in consequence of the evaporation of the iodine ; light also appears to exert LlQUORES. 1121 a deleterious influence upon it. It should, therefore, be kept in well stopped bottles, and in a dark place. Properties and Uses.—Compound Solution of Iodine possesses all the virtues of iodine, and may be used advantageously in scrofulous, syph- ilitic, and all tuberculous diseases, or wherever iodine is indicated. The dose is six drops, in one or two tablespoonfuls of sweetened water, repeated three times a day, and gradually increased to twenty or thirty drops. Twelve drops is equal to about half a grain of iodine. Liquor Magnesia Citratis. Solution of Citrate of Magnesia. Preparation.—Take of Carbonate of Magnesia five drachms ; Citric Acid seven drachms and a half; Syrup of Citric Acid two fluidounces; Water a sufficient quantity. Dissolve the Citric Acid in four fluidounces of Water, and add to the solution four drachms of the Carbonate of Magnesia, previously rubbed with three fluidounces of Water. When the reaction has ceased, filter the solution into a strong glass bottle, of the capacity of twelve fluidounces, into which the Syrup of Citric Acid has been preA'iously introduced. Rub the remaining Carbonate of Mag- nesia with tAvo fluidounces of Water, and pour the mixture into the bottle, which is then to be tightly corked, and secured with twine. Lastly, shake the mixture occasionally until it becomes transparent.— U. S. History.—This preparation is an aqueous solution of Citrate of Mag- nesia ; it contains Citric Acid in excess to the quantity of about fourteen and a half grains, with Carbonic Acid and syrup to render it more pal- atable. If the magnesia be good, it will be wholly dissolved by the citric acid; if it be impure there will be more or less of a sediment in the solution. When the first four-fifths of the magnesia are dissolved in the acid, an acid citrate of magnesia is formed ; this being filtered upon the syrup of citric acid, has its acidity increased. The addition of the remainder of the magnesia gives rise to a further quantity of citrate with disengagement of carbonic acid, which is retained within the bottle by immediately corking it. It forms a transparent solution, having an agreeable, lemonade-like taste, and consists of one equivalent of citric acid and three of magnesia. It is not permanent in its character, but forms a deposit on keeping, and is intended as an extemporaneous solution, to be prepared only as required. Properties and Uses.—Solution of Citrate of Magnesia, is a pleasant, cooling purgative, acting mildly upon the bowels. The dose as a cathartic is about twelve fluidounces ; as a laxative, half that quantity. Liquor Potassae. Solution of Potassa. Preparation.—Take of Carbonate of Potassa a pound; Lime half a pound; Boiling Distilled Water a gallon. Dissolve the Carbonate of Potassa in half a gallon of the Water. Pour a little of the Water on the Lime, and when it is slaked add the remainder. Mix the hot liquors, 71 1122 Pharmacy. and boil for ten minutes, stirring constantly ; then set the mixture aside, in a covered vessel, until it becomes clear. Lastly, pour off the super- natant liquor and keep it in well stopped bottles of green glass. The specific gravity of this solution is 1.056.— U. S. History.—In this process, the potassa is obtained in a caustic state by means of the hydrate of lime, the lime of which unites with the carbo- nic acid of the carbonate of potassa, and forms a precipitate of carbonate of lime; while its water combines with the potassa forming a solution of potassa. The solution should not be strained, on account of the tendency to absorb carbonic acid by prolonged exposure to the air, and which, of course, would deteriorate its strength and value. The reason for directing it to be kept in green glass bottles, is, that the solution exerts an action on white flint-glass. Solution of Potassa is an alkaline, inodorous, transparent, colorless liquid, having an acrid, caustic taste. It dissolves animal and vegetable substances, as gum, resins, and extractive matter, and forms soaps with fats and oils. When rubbed between the fingers it produces a soapy feeling, owing to the cuticle being partially acted upon by it. When prepared for medical purposes it is commonly more or less impure, con- taining either some free lime, undecomposed carbonate, or other foreign matters ; for chemical purposes, it requires to be pure. When exposed to the air it absorbs carbonic acid, for which it has a strong affinity, and should therefore always be preserved in thoroughly-stopped bottles. It is incompatible with all salts of ammonia, calomel, corrosive sublimate, acids, acidulous salts, and acidulous solutions of metallic and earthy preparations. Properties and Uses.—Solution of Potassa is employed in medicine as an antacid, antilithic, and diuretic. Although it can exert no solvent influence upon calculi once formed in the bladder, yet it may overcome the tendency to an excess of uric acid or the insoluble urates, which so often give rise to gravel and stone. For this purpose, however, it is inferior to solutions of the carbonated alkalies, which may be adminis- tered for a longer time without occasioning any injurious influences. The long-continued use of solution of potassa debilitates the stomach, and otherwise impairs the system. As an antacid, the solutions of the carbonates are preferable. In scalding of the urethra accompanying gonorrhea, combined with ten or twelve drops of laudanum, liquor potassa will be found to afford prompt relief. The dose is from ten to thirty minims, repeated two or three times a day; and it may be admin- istered in sweetened Avater, or in some mucilaginous liquid. When taken in quantities to injure the stomach, or in an undiluted state, oils, vinegar, and lemon-juice, which neutralize the alkali, are the proper antidotes. Off. Prep.—Potassa cum Calce. LlQUORES. 1123 Liquor Potassae Citratis. Solution of Citrate of Potassa. Neutral Mixture. Preparation.—Take of Citric Acid half an ounce; Oil of Lemons two minims; Water half a pint; Bicarbonate of Potassa a sufficient quantity. Rub the Citric Acid with the Oil of Lemons, and afterward with the Water till it is dissolved; then add the Bicarbonate of Potassa gradually till the Acid is perfectly saturated; lastly, filter: or, Take of Fresh Lemon-juice half a pint; Bicarbonate of Potassa a sufficient quantity. Add the Bicarbonate gradually to the Lemon-juice till it is perfectly saturated; then filter.— U. S. History.—In these formulae the citric acid combines with the potassa of the bicarbonate, and carbonic acid is set free, forming a solution of Citrate of Potassa, containing free carbonic acid. The citric acid and oil of lemon, in the first process, are intended to supply the absence of fresh lemon-juice. When the solution is made with citric acid it is colorless, and when with lemon-juice, it is greenish. Filtering is directed for the purpose of removing any foreign or undissolved substances. The point of saturation may be known by the liquid effecting no change in blue and red litmus paper. Properties and Uses.—This solution is a refrigerant diaphoretic, and may be used in all fevers attended Avith a dry, hot skin; it is also useful in allaying irritability of the stomach. It forms a very grateful draught to the patient. Spirits of Nitre, Solution of Sulphate of Morphia, Tinc- ture of Aconitum or Digitalis, are frequently added to assist in fulfilling required indications. The dose is half a fluidounce, or an ordinary tablespoonful, diluted with water, and repeated every one, two, or three hours according to the urgency of the symptoms. It may be sweetened with sugar if desired. Liquor Sod^e Chlorinate. Solution of Chlorinated Soda. Labar- raque's Disinfecting Liquid. Preparation.—Take of Chlorinated Lime (chloride of lime) a pound; Carbonate of Soda two pounds; Water a gallon, and a half. Dissolve the Carbonate of Soda in three pints of the Water, with the aid of heat. To the remainder of the Water add, by small portions at a time, the Chlorinated Lime previously well triturated; stirring the mixture after each addition. Set the mixture by for several hours that the dregs may subside; then decant the clear liquid, and mix it with the solution of Carbonate of Soda. Lastly, decant the clear liquor from the precipi- tated Carbonate of Lime, pass it through a linen cloth, and keep it in bottles secluded from the light.— U. S. History. — This preparation was originally introduced by a Parisian apothecary, named Labarraque, as a disinfecting agent. By the above process, a solution of carbonate of soda is decomposed by one of chlori- nated lime; the carbonic acid of the soda unites with the lime and 1124. Pharmacy. precipitates as carbonate of lime, Avhile the chlorine of the chlorinated lime combines with the soda, forming a chlorinated soda in solution; the solution is rendered more permanent by the excess of carbonate of soda, which is present, when prepared as above. Further analyses are required to determine the exact constitution of this solution. Properties and Uses.—Solution of Chlorinated Soda is a powerful dis- infectant, antiseptic, stimulant, and resolvent. Its disinfectant property is owing to its absorption of carbonic acid, and gradual evolution of chlorine, when exposed to the air; and for which purpose it may be used in the rooms of patients with infectious diseases, by sprinkling some of it on the bed, floor, or other parts of the room. As an internal agent it is used in putrid or malignant diseases, as scarlatina, typhus, small-pox, etc., especially when attended with great debility, offensive evacuations, and a dry, brown-furred tongue; in which it promotes the secretions and evacuations, increasing the urine, and pro- ducing gentle diaphoresis, with a beneficial change in the condition of the tongue. It has likewise been efficaciously employed in dysentery, and diarrhea, attended with very offensive evacuations, in dyspepsia accompanied with eructations of a fetid nature, also in glandular enlarge- ments, and in mucous discharges of a chronic character. In asphyxia caused by sulphureted hydrogen, it is an efficient antidote. It has also been highly recommended in various other diseases, as scrofula, chronic diseases of the skin, secondary syphilis, amenorrhea, dysmenorrhea, and bilious affections. From thirty drops to half a fluidrachm, in a cup- ful of water, is the dose, and which may be repeated every two or three hours. As an external remedy, it forms a valuable application to can- cerous, scrofulous, syphilitic, and gangrenous ulcers, and other affections attended with fetor, as carbuncle, ozcena, ulceration of the gums, putrid sore-mouth and throat, mercurial sore-mouth, fetid discharges from the vagina, uterus, and bladder; and has been successfully applied to burns, and cutaneous diseases, as tinea capitis, scabies, herpes, psoriasis, etc. Applied frequently to sore nipples, it is a superior remedy. When used externally, it may be diluted with from five to thirty parts of water, according to circumstances. ______ LOTIONES. Lotions, or Washes. These comprise all compounds used as external washes and collyria, in which vegetable or mineral substances are dissolved in water or spirits, but which do not strictly class with infusions, liniments, mix- tures, or tinctures. Lotio Alkalina. Alkaline Wash. Preparation.—-Take of Carbonate of Soda (Sal Soda) two drachms; Warm Rain-Water one quart. Dissolve: or, Make a weak Ley by adding Hard Wood Ashes to Hot Water. LOTIONES. 1125 Properties and Uses.—This Avash is extensively and efficaciously em- ployed by Eclectics, as an application to the surface of the body and limbs in all febrile and inflammatory diseases, and in chronic affections. In the former cases it is applied several times a day, especially when the acute symptoms run high; in the latter affections it is commonly used once or twice a week. The surface should always be well rubbed and dried immediately after each application. Frequently, when exter- nal stimulus is also required, the above proportion of water is lessened one-fourth or one-half, and the balance of the quantity made up by the addition of whisky or other spirit. Lotio -^Etheris Composita. Compound Ethereal Lotion. Evaporating Lotion. Preparation. — Take of Sulphuric Ether, Rectified Alcohol, Solution of Acetate of Ammonia, each, one ounce and a half; Rose-Water three ounces and a half. Mix together. Properties and Uses.—This lotion may be used to produce a refrige- rant or stimulant influence according to its mode of employment. Applied to a surface and allowed to evaporate by free exposure, it acts as a refrigerant; but if the evaporation is prevented by covering the part to which it is applied with the hand or a cloth, it acts as a stimulant. The Solution of Acetate of Ammonia, largely diluted, (without the addi- tion of ether or alcohol), is a superior cooling lotion in all cases of fever where there is a hot and dry state of the surface, often of itself inducing diaphoresis. Lotio Boracis. Borax Lotion. Cooling Wash. Preparation.—Take of Borax, in powder, one ounce ; Rain Water one quart. Dissolve. In this preparation, soft River Water may be substi- tuted for Rain Water, when this latter cannot be obtained. Properties and Uses.—This forms a cooling application, and may be used in inflammation of the eyes, sore and inflamed nipples, aphthous ulcerations of the mouth and fauces, and other irritated or inflamed mu- cous surfaces. Lotio Boracis cum Morphine. Borax Lotion with Morphia. Preparation.—Take of Borax, in powder, half an ounce; Sulphate of Morphia six grains; Decoction of Golden Seal eight fluidounces. Dissolve the Borax and Morphia in the Decoction. Properties and Uses.—This forms a cooling and mild anodyne wash, and may be used in inflammation of the eyes, sore and inflamed nipples, pruritus vulva, aphthous ulcerations of the mouth and fauces, and other irritated or inflamed mucous surfaces. Lotio Glycerini. Glycerin Lotion. Preparation.—Take of Glycerin half an ounce ; Distilled Water half a pint. Mix. 1126 Pharmacy. Properties and Uses.—This lotion has been recommended in eczema, lichen, and other cutaneous diseases; also as an application to the meatus externus in cases of deafness owing to a want of secretion of cerumen. Lotio Hydrastis Composita. Compound Lotion of Golden Seal. Preparation.—Take of Strong Decoctions of Green Tea, and Golden Seal, each one pint; Sulphate of Zinc, Gunpowder, dried Sulphate of Iron, of each two drachms. Mix the decoctions, then add the remainder of the articles, and agitate briskly. After solution and decomposition have ceased, and the precipitate has subsided, pour off the supernatant liquid. Properties and Uses.—This lotion is principally employed as a colly- rium in chronic ophthalmic diseases, but it may be advantageously employed in all chronic affections of mucous surfaces, as an external application. The affected parts are to be bathed with it several times a day. Lotio Hydrastis et Aconiti. Lotion of Golden Seal and Aconite. Preparation.—Take of Golden Seal, in powder, four drachms ; Boiling Water four fluidounces ; Tincture of Aconite one fluidrachm. Add the Golden Seal to the Water, and digest for three hours by a gentle heat; then filter and evaporate to two fluid ounces, to which add the Tincture of Aconite. Properties and Uses. — This forms a superior application to the eye in many cases of disease of that organ; it may be applied by means of a camel's hair pencil, or by dropping a minim or two on the eyeball. I have likewise found immense benefit in these cases, by substituting for the Tincture of Aconite, a fluidrachm or two of the Saturated Tincture of Black Cohosh. Some physicians employ Hydrastin in preparing the above formula, but as this is insoluble in water, it can effect but little influence. This preparation will also be found of service in chronic mucous difficulties, as vaginal leucorrhea, etc., used as a wash or injec- tion.—J. K. Lotio Juglandis. Walnut Lotion. Preparation.—Take of Extract of green Walnut Shells six grains; Distilled Water fifty grains. Mix and dissolve. Properties and Uses.—This is recommended as an efficacious agent in enlargement of the tonsils, and is stated to be very prompt in its effects. It is applied to the parts by means of a camel's hair pencil. Lotio Lobelia Composita. Compound Lobelia Lotion. Herpetic Wash. Preparation.—Take of Bayberry Bark, Lobelia Leaves and Seed, Yel- low Dock Root, each, in powder, two drachms; Vinegar one pint. Mix all together, and allow them to macerate for seven days, and filter; or make the lotion by displacement. Lotiones. 1127 Properties and Uses.—This preparation forms an excellent local appli- cation to several species of cutaneous disease, also to erysipelas and erysipelatous inflammations. It is frequently prepared with Spirits instead of Vinegar, especially where more active stimulation is desired. In erysipelas, half a pint of a saturated solution of Muriate of Ammonia, may be added to the above quantity, with advantage. Lotio Myrrhae Composita. Compound Myrrh Lotion. Stimulating Eyewater. Preparation.—Take of Myrrh, in powder, one ounce ; Sulphate of Zinc, Acetate of Lead, of each half an ounce; Boiling Water two quarts. Add the Myrrh and the Salts to the Water, and allow them to macerate for seven days, and then filter. In the preparation of this lotion, a decom- position necessarily ensues. Properties and Uses.—Compound Myrrh Lotion is chiefly employed in cases of chronic ophthalmia; it will, however, be found useful in all chronic mucous diseases. It is usually applied three or four times a day, and must not be used during the presence of inflammation. When too severe it may be diluted with water. Lotio Refrigerans. Cooling Lotion. Saline Wash. Preparation.—Take of fine Salt an ounce; Spirits, Vinegar, and Rain Water, of each, half a pint. Mix the fluids together, and then add the Salt. In the absence of Rain Water, clear river water may be substi- tuted. Properties and Uses.—This Lotion is extensively employed as a cooling application, in cases of pain or determination to the head, during fevers, inflammation of the brain, dropsy, etc. It is used cold or tepid, accord- ing to the benefit received from its application at these temperatures. Lotio Sassafras. Sassafras Lotion. Preparation.—Take of Pith of Sassafras one ounce; Rose Water a sufficient quantity. Mix, let them stand for an hour or two and filter. Properties and Uses.—This is an extemporaneous preparation, and is principally used in acute ophthalmia. A similar preparation of Marsh Mallow Root, Elm Bark, or Buckhorn Brake, will be found equally available. Lotio Sodii Composita. Compound Soda Lotion. Preparation.—Take of Rock Salt three ounces ; Sulphate of Zinc one ounce; Red Oxide of Iron (Sesquicarbonate) eight grains; Rain Water, or clear River Water one pint. Add the articles together, and form a solution; and when the precipitate formed, has subsided, pour off the supernatant liquid. Properties and Uses.—Used as a stimulating collyrium in chronic oph- thalmic diseases. 1123 Pharmacy. Lotio Zinci Composita. Compound Lotion of Zinc. Preparation.—Take of Sulphate of Zinc, Rock Alum, each, one scru- ple ; Distilled Water two pints. Mix, and when dissolved filter. Properties and Uses.—This lotion is used as a stimulating application to the eye in cases of films, specks, opacities, etc.; to abnormal growths on mucous surfaces; to indolent ulcers with fungous groAvths; and to gangrene. MISTUR^E. Mixtures. By mixtures is meant all those preparations, containing Oleaginous, Mucilaginous, Albuminous, or Saccharine Substances, which are used internally, and cannot properly be classed with infusions, decoctions, syrups, tinctures, etc. ; also compounds in which Insoluble Substances, whether liquid or solid, are suspended in aqueous fluids by the interven- tion of some viscid matter. Mistura Camphors Composita. Compound Mixture of Camphor. Preparation. — Take of Camphor Water, Peppermint Water, and Spearmint Water, each, one fluidounce; Camphorated Tincture of Opium two fluidrachms. Mix together. Properties and Uses. — This is a very efficacious agent in allaying nausea and vomiting. It was extensively and successfully employed by the Eclectics in the nausea and vomiting attending Asiatic cholera. It possesses the virtues of the several articles entering into its composition, without the stimulating influence of the alcohol, which enters into their tinctures, upon already partially inflamed mucous surfaces. The dose is from a teaspoonful to a tablespoonful every five minutes, if the patient be vomiting ; and every ten minutes if he be only nauseated. Mistura Cajuputi Composita. Compound Cajeput Mixture. Hunn's Drops. Preparation. — Take of Oils of Cajeput, Cloves, Peppermint, and Anise, each, one fluidounce; Rectified Alcohol four ounces. Dissolve the Oils in the Alcohol. Properties and Uses.—This is a very valuable stimulant and antispas- modic preparation, and has been successfully used in colic, cramp of the stomach or elsewhere, flatulence, pains in the stomach or bowels, painful diarrhea, cholera-morbus, Asiatic cholera, and in all cases where stimu- lant and antispasmodic action is desired. During the cholera of 1849- 50-51, it Avas extensively used by the Eclectics for the purpose of over- coming violent spasmodic action, in the doses of one or two fluidrachms, every ten or fifteen minutes ; one or two doses, generally succeeded in relieving the pains and spasms when all other means had failed. The MlSTUR^E. 1129 ordinary dose is from ten drops to half a fluidrachm. It should be given in simple syrup, mucilage of slippery elm, or in hot brandy and water, sweetened. Care should be taken not to introduce too much of this pre- paration into the stomach at any one time, as a large proportion of it would produce inflammation of the stomach. It is a very valuable agent, when properly used, and should always be kept by every physician and druggist. Mistura Chenopodii Composita. Compound Wormseed Mixture. Worm Mixture. Preparation. — Take of Castor Oil one fluidounce; Wormseed Oil, Anise Oil, and Tincture of Myrrh, of each, one fluidrachm. Mix. Properties and Uses.—This is an excellent vermifuge, and may be used in doses of one teaspoonful for an adult, to be repeated three or four times a day, and after having been taken for three successive days, to be folloAved by a cathartic. This somewhat resembles "Fahnestock's Vermifuge," which is said to be composed of, Castor Oil one fluidounce; Oil of Wormseed one fluidounce; Oil of Anise half a fluidounce ; Tinc- ture of Myrrh half a fluidrachm ; Oil of Turpentine ten minims ; Croton Oil one minim. Mix. The dose is a teaspoonful for an adult, every two hours, to be continued for ten or twelve hours. Mistura Copaibae Composita. Compound Copaiba Mixture. Diuretic Drops. Prepjaration.— Take of Spirit of Nitric Ether and Oil of Almonds, each two fluidounces ; Copaiba, and Oil of Turpentine, of each, one fluid- ounce ; Camphor, in powder, one scruple. Mix together the liquids, then add the Camphor, and agitate briskly. Properties and Uses.—This forms a diuretic mixture, which has been successfully and extensively used in gonorrhea, gleet, scalding of urine, and urinary affection*. The dose is one fluidrachm, three times a day, in some tea or mucilage. It should be well agitated previous to taking it. There are various mixtures of Copaiba in use for the cure of gonor- rhea, and as several of them have been found efficacious, I give the for- mula for preparing them :— 1. Take of Copaiba, Spirit of Nitric Ether, Compound Spirits of Lavender, Tincture of Muriate of Iron, of each, one fluidounce. Mix. The dose is a teaspoonful three times a day. 2. Take of Oil of Cubebs, Oil of Anise, Copaiba, Tincture of Opium, Tincture of Muriate of Iron, of each, one fluidounce. Mix. The dose is a teaspoonful three times a day. The two preparations above are very disagreeable to the taste, but very efficacious in gonorrhea, after the active symptoms have subsided. They must be agitated thoroughly, previous to taking each dose, and in order to protect the teeth from the injurious action of the acid in the Tincture of Muriate of Iron, it is 1130 Pharmacy. recommended to rinse the mouth immediately after taking each dose, with a solution of Bicarbonate of Potassa. 3. Take of Solidified Copaiba two ounces ; White Wax one ounce; Oil of Cubebs, Oil of Spearmint, of each, one fluidrachm; Nitre, finely pulverized, two drachms. Melt the Wax, add the Oils, and then the Copaiba ; stir all well together, and finally, add the Nitre. This forms a paste much used for the cure of gonorrhea. The dose, is a quantity about the size of a small chestnut, three times a day. 4. Take of Alum, in powder, one drachm; Precipitated Carbonate of Iron half an ounce; Pulverized Cubebs one ounce ; Copaiba a sufficient quantity to form a kind of paste. The dose is the same as in the pre- ceding preparation. Mistura Glycyrrhiza Composita. Compound Liquorice Mixture. Preparation.—Take of Extract of Liquorice, in powder, Gum Arabic, in powder, Sugar, each, half an ounce; Camphorated Tincture of Opium two fluidounces; Tincture of Bloodroot a fluidounce; Spirit of Nitric Ether half a fluidounce ; Water twelve fluidounces. Rub the Liquorice, Gum Arabic and Sugar with the Water gradually poured upon them; then add the other ingredients, and mix. Properties and Uses.—This forms an excellent cough mixture, and may be used in catarrhal affections, after the subsidence of the more active symptoms, and when expectoration is present. For an adult the dose is a tablespoonful; for a child two or three years old a teaspoonful. It should be well agitated previous to taking it. Mistura Olei Camphorata. Camphorated Mixture of Oils. Preparation.—Take of the Oils of Cloves, Cajeput and Amber, (rec- tified), and Camphor, each, half an ounce. Mix the Oils together, and dissolve the Camphor in the mixture. Properties and Uses.—This is intended for the relief of toothache. The decayed portion of the tooth is to be cleansed and dried, and then a few drops of the mixture on cotton applied to the part; continue the application two or three times in the same manner, and leave the last in the tooth. This has proved very efficacious, and has been extensively sold throughout the country as " Parisen's Vegetable Specific." It will not be amiss to give, at this place, another preparation for tooth- ache, which I have found of service. Take of Opium, and Nitre, each, two ounces; Camphor an ounce and a half; Galls, in powder, four ounces; Alcohol a pint and a half Place the articles in the Alcohol, macerate for fourteen days, and filter. To be applied the same as with the pre- ceding mixture. Various other agents, as Solution of Tannic Acid, or Gallic Acid in Alcohol, etc., have been recommended for relieving toothache, but the above will be found to answer the purpose admirably. (See Carvacrol.) Morphia, 1131 Mistura Olei Composita. Compound Mixture of Oils. Vermifuge Oil. Preparation.—Take of Castor Oil, and Wormseed Oil, each, one ounce; Oil of Turpentine, and Oil of Anise, of each, half an ounce. Mix together. Properties and Uses.—This forms an efficacious remedy for worms, and may be given in teaspoonful doses to an adult, and repeated every two hours. After its employment for two or three days, a purgative must be administered.— T. V. M. Mistura Sanguinaria Composita. Compound Mixture of Bloodroot. Cough Drops. Preparation.—Take of Syrup of Ipecacuanha, Syrup of Squill, Tinc- ture of Bloodroot, Syrup of Balsam Tolu, Camphorated Tincture of Opium, each, one ounce. Mix together. Properties and Uses.—This is a very efficacious preparation in severe cough from colds, catarrhal or bronchial irritations. The dose is from half a fluidrachm to a fluidrachm whenever the fit of coughino- is severe. I have used it for many years in practice, with much benefit. A very pleasant preparation for cough, is composed of Oil of Anise, Oil of Sweet Almonds, Tincture of Balsam Tolu, Canada Balsam, Madeira Wine, each, one ounce. Mix. The dose is from ten to twenty drops, three or four times a day, in a little elm or flaxseed infusion. It assists expectoration, and affords great relief in tickling coughs.—J. K. Mistura Spiritus Vint Gallici. Brandy Mixture. Preparation.—Take of Brandy, Cinnamon Water, each, four fluid- ounces ; the yelks of two Eggs; Refined Sugar half an ounce; Oil of Cinnamon two minims. Mix together. Properties and Uses.—This forms a nutritive and stimulating prepara- tion, especially adapted to the stage of prostration in low forms of fever, and in cases of much debility from various other causes. MORPHIA. Preparations of Morphia, Morphia. Morphia. Preparation.—Take of Opium, sliced, a pound; Solution of Ammonia six fluidounces ; Distilled Water, Alcohol, and Animal Charcoal, of each, a sufficient quantity. Macerate the Opium with four pints of Distilled Water for twenty-four hours, and, having worked it with the hand, digest for twenty-four hours, and strain. In like manner, macerate the residue twice successively with the same quantity of Distilled Water, and strain. Mix the infusions, evaporate to six pints, and filter; then add firstly, five pints of Alcohol, and afterward three fluidounces of the 1132 Pharmacy. Solution of Ammonia, previously mixed with half a pint of Alcohol. After twenty-four hours, pour in the remainder of the Solution of Am- monia, mixed, as before, with half a pint of Alcohol; and set the liquor aside for twenty-four hours, that crystals may form. To purify these, boil them with two pints of Alcohol till they are dissoh'ed, filter the solution, while hot, through Animal Charcoal, and set it aside to crys- tallize.— U S. History.—Water will extract Morphia from Opium as well as Acetic Acid, especially if the opium be, as directed, properly comminuted by working it with the hand, beside which, it possesses an advantage over acids in taking up less of the narcotina. The several macerations in water, assisted each time by kneading, nearly, if not quite, exhaust the drug of its morphia. The next step is to concentrate the infusions after having mixed them together ; after this is effected, solution of ammonia is added to the concentrated infusion for the purpose of decom- posing the meconate or other salt of morphia which may be present in it. The ammoniacal solution unites with the acid, and the vegetable alkali is precipitated ; but as it usually carries with it a large proportion of coloring matter, which is very troublesome to remove, alcohol is pre- viously added to the infusion. The alcohol dissolves the coloring matter as soon as it is separated by the ammonia, in consequence of which a much purer morphia is thrown down. By adding the ammonia in two portions, and at different stages of the process, the morphia is more slowly separated, and its impurities can be more readily removed, than if the whole were disengaged at once. Care must be taken to add no more ammonia than is necessary to saturate the acid present, for if there be an excess of ammonia, it will dissol\re a portion of the morphia, and thus lessen the product. The first crystals obtained have a light-yel- lowish color; these are boiled in alcohol, and the solution filtered through animal charcoal, which removes all coloring matter. In this process alcohol at 25° Baume (sp. gr. 0.9032) is preferable to highly rectified spirit, as it is less liable to hold the morphia in solution when cold ; and likeAvise, care should be observed in using a solution of ammonia of the officinal standard. Any morphia which may remain in the alcohol may be obtained by distillation of the latter, and when suf- ficiently concentrated, be purified by a separate operation. By this process, the morphia obtained always contains a portion of narcotina, which may be removed by ether, which dissolves the latter principle, and leaves the morphia untouched. Or diluted acetic acid may be added, which will dissolve the morphia and leave the narcotina; the former may be obtained from the acetic solution by saturation of the acid with ammonia. Or, dissolve the morphia in dilute muriatic acid, and boil the solution with lime, which throws doAA'n the narcotina, and holds the morphia dissolved. The liquid being filtered yields the morphia Morphia. 1133 upon the addition of muriate of ammonia. Other means have been pur- sued, but it is not necessary to name them here. Various other processes for procuring morphia have been pursued and proposed, but, probably, none are better adapted to the purpose, especially when small quantities are required, than the one given above, from the United States Pharmacopoeia. As opium varies in quality, so likewise does it vary in the proportion of the morphia which it contains ; from nine per cent, to fourteen, is most commonly obtained, and much less than even nine per cent, when the drug is of very inferior quality, or when the process has been carelessly pursued and the opium not completely exhausted. The average amount of morphia yielded by opium may be stated at from ten to twelve per cent. Morphia is in small, colorless, shining crystals, without odor, and quite bitter. At a moderate heat it parts with its ay ate r of crystallization, loses its crystalline form, and becomes opake and Avhite; if the temper- ature be increased, it melts and becomes a yelloAvish fluid from partial decomposition, which, upon cooling, assumes a Avhite and crystalline appearance. When heated in the open air, it burns Avith a bright flame, and is wholly dissipated at a red-heat. It is nearly, if not quite, inso- luble in cold water or ether; is sparingly soluble in cold alcohol; is soluble in someAvhat less than one hundred parts of boiling water; is freely soluble in boiling alcohol, which deposits it on cooling; and is also partly dissolved by the fixed and vegetable oils. Its alcoholic solu- tion changes red litmus paper to blue, and yellow turmeric to brown. It enters into combination with the acids, forming salts which are, for the most part, soluble, and decomposed by the alkalies. It is dissolved by solutions of potassa and soda, Avhich, when exposed to the air, slowly precipitate it in consequence of the carbonic acid which they absorb. Solution of ammonia likewise dissolves it; so that in precipitating mor- phia by ammonia, great care must be taken to avoid adding it in excess. Nitric acid in contact Avith morphia or its salts, changes them to a blood- red color Avhich finally becomes yellow. A solution of iodic acid, or an acidulous iodate is reddened by them, with evolution of iodine. With sesquichloride of iron, or the salts of the sesquioxide, morphia, its ace- tate and oxalate, form a fine blue color, Avhich is destroyed upon the addition of a large quantity of water, or by acids or alkalies. Pseudo- morphia, a principle discovered by Pelletier, and which is not possessed of poisonous properties, also becomes red under the action of nitric acid, and produces a blue color with the salts of sesquioxide of iron, so that these results are not positive indications of the presence of morphia. The terchloride of gold precipitates morphia at first yellow, then bluish, and finally violet. Potassa or soda precipitates morphia from its solu- tions, but redissolves it, Avhen added in excess. Infusion of galls, and all vegetable solutions containing tannic acid precipitate morphia, forming a 1134 Pharmacy. tannate of morphia soluble in acetic acid. Pure gallic acid, according to Dublanc, does not precipitate it. The solutions of chlorine and morphia when mixed, become of a dark-brown color on the addition of ammonia, which is removed by a fresh addition of chlorine. Anhydrous morphia is stated to consist of one equivalent of nitrogen 14, thirty-five of car- bon 210, tAventy of hydrogen 20, and six of oxygen 48=292. The crystals contain about 5.8 per cent., or two additional equivalents of water 18=310. Properties and Uses. — Morphia is the narcotic principle of opium, somewhat differing from this drug, however, in its effects upon the sys- tem, and which difference is, probably, owing to its peculiar combination with other principles existing in the opium. From its insolubility in water, it is less certain in its effects than some of its salts, as its manner and extent of action depend greatly on the presence or absence of acid in the stomach, as well as on the peculiar nature of the acid. Hence, its salts are always preferred, among which, the principal ones employed are the acetate, muriate, and sulphate. All these are soporific, anodyne, and diaphoretic, but differ from the actions of opium, in being less stim- ulating, less inclined to effect constipation, and less liable to produce the subsequent symptoms of headache, nausea, etc. Their principal em- ployment is to abate pain, promote sleep, and tranquilize the system Avhen in a state of restlessness from nervous irritation, or other cause. Opium, hoAvever, is more efficient in low forms of disease, as a stimulant, and also for the suppression of morbid discharges. In delirium tremens they are especially useful, and I have found more benefit in these cases, from the following preparation, than any other. Take of Sulphate of Quinia twelve grains; Sulphate of Morphia one grain ; mix, and divide into six powders. Of these give one powder every hour, until the patient sleeps. Generally but two or three powders are required before the patient falls into a quiet sleep, with considerable moisture of the surface. Morphia and its salts are more acceptable to the stomach, in many cases, than opium or its tincture, and where they cannot be em- ployed internally, from whatever cause, they may be applied upon a vesicated surface from which the cuticle has been removed, in double or triple the internal dose, and will exert the same influence upon the sys- tem as when received into the stomach. Thus applied, they are very effectual in relieving severe neuralgic pains, and in overcoming obstinate sickness of the stomach. The proper way is to apply them as near the affected part as possible, or, when it is desired to bring the system under its influence, to the epigastric region. Given in doses not sufficient to cause sleep, they frequently occasion troublesome cerebral symptoms, almost approximating delirium, but which gradually pass off sponta- neously, or disappear upon the administration of another dose. Given in large non-medicinal doses, morphia, as well as its salts, acts as a narcotic poison, requiring the same toxicological treatment as in the Morphia. 1135 case of poisoning by opium. Strong coffee has been used as an antidote, and with apparent benefit. The dose of morphia and its salts, is from one-eighth of a grain to a quarter; and one-sixth of a grain is about equivalent to a grain of ordi- nary opium. Off. Prep.—Morphiae Acetas; Morphiae Murias; Morphiae Sulphas; Ferri et Morphiae Tartras; Quiniae et Morphiae Tartras. Morphia Acetas. Acetate of Morphia. Preparation.—Take of Morphia, in powder, (freed from narcotina by boiling with Sulphuric Ether), an ounce; Distilled Water half a pint; Acetic Acid a sufficient quantity. Mix the Morphia with the Water; then carefully drop in the Acid, constantly stirring, until the Morphia is satu- rated and dissolved. Evaporate the solution, by means of a water-bath, to the consistence of syrup. Lastly, dry the Acetate with a gentle heat, and rub it into powder. It should be kept in a darkened vial, as light gradually decomposes it—changing it to a dark color.— U S. History.—In this process, morphia is saturated with acetic acid, which is preferred to vinegar, on account of leaving no impurity in the acetate. The solution of the morphia in the water, upon the addition of a suffi- cient quantity of acetic acid, is evidence of its saturation; but a slight excess of acid is of no importance, as it is expelled during the evaporat- ing process. The employment of too great a degree of heat must, how- ever, be avoided, lest the salt become decomposed by losing a part of its acetic acid, and leaving a corresponding portion of its morphia undis- solved. Crystals of acetate of morphia may be obtained provided the evaporation be checked at a certain point; but as it is always a matter of more or less difficulty, it is preferred to continue the evaporation to dryness. One advantage accruing from the use of diluted acetic acid of sp. gr. 1.004, in the preparation of the acetate, is, that while it dis- solves the morphia, it leaves the narcotina, should any be present, untouched. Acetate of morphia is in the form of a snowy white, obscurely crys- talline powder, or if crystallized, it is in slender acicular and fasciculated crystals. It is inodorous, but possesses an intense, peculiar, bitter taste. Water dissolves it readily, though not entirely,—this is owing to a loss of some of its acid during evaporation to dryness, so that there is not enough present to hold the morphia in solution. Consequently, when it is required to use the acetate in solution, a few drops of distilled vinegar added, will render it completely soluble. It is not so readily soluble in alcohol as in water. A strong heat decomposes, and entirely dissipates it. Its aqueous solution, moderately concentrated, is affected by heat, nitric acid, and sesquichloride of iron, in the same manner as morphia; and the alkalies or alkaline earths precipitate morphia from it, but redissoh e it if added in excess. Diluted sulphuric acid added to 1.136 Pharmacy. the salt, disengages acetic fumes, and imparts an acetous odor to the solution. It is supposed to consist of one equivalent of base 296.35, one of acid 51.48, and one of water 9=356.83. OAving to unskillful preparation it may be adulterated with coloring matter, which may be knoAvn by the want of its proper whiteness; but it may likewise, be adulterated with various white powders. In addition to the above tests of its purity, the following formula of the Edinburgh College will be found generally sufficient to detect the most part of adul- terations: " One hundred measures of a solution of ten grains in a half a fluidounce of water and five minims of acetic acid, heated to near 212°, and decomposed by a faint excess of ammonia, yield by agitation a precipitate which in 24 hours occupies 15.5 measures of the liquid." Properties and Uses.—Acetate of Morphia exerts a similar influence upon the system as the other salts of Morphia, and is preferred by some practitioners to them; but I have not found the combination of any acid to appreciably affect the therapeutical influence of the morphia. It may be substituted for opium, as a general rule, or for any of the other salts of morphia. The dose to produce an anodyne or soporific effect is from one-eighth of a grain to one-quarter; but under certain excitable con- ditions of the system, even more may be required. One-sixth of a grain is about equivalent to a grain of opium. It is sometimes used externally, applied to vesicated surfaces, for the purpose of affecting the system. Internally, it may be given either in the form of pill or solu- tion. >A solution (Liquor Morphias Acetatis) may be formed by adding ten grains of Acetate of Morphia to one fluidounce and a half of Distilled Water, to which add half an ounce of proof Spirit and five minims of Diluted Acetic Acid. The dose of this is from ten to fifteen drops. The alcohol is added to prevent spontaneous decomposition. (See Ferri et Morphiae Tartras.) Morphia Murias. Morphia Hydrochloras. Muriate of Morphia. Hydrochlorate of Morpldu. Preparation.—Take of Morphia, in powder, an ounce; Distilled Water half a pint; Muriatic Acid a sufficient quantity. Mix the Morphia with the Water; then carefully drop in the Acid, constantly stirring, till the Morphia is saturated and dissolved. Evaporate the solution by means of a water-bath, so that it may crystallize upon cooling. Dry the crys- tals upon bibulous paper.— U. S. History.—By the above process, Morphia is saturated with muriatic acid, of which saturation its complete solution in the water is an indica- tion. An excess of acid may be known by litmus paper, which becomes reddened if such be the case. Muriate of Morphia is usually met with in the form of a pure-white powder; but when crystallized it forms beautifully radiated tufts of deli- cate feathery or satiny needles. It is inodorous, intensely bitter, perma- Morphia. 1137 aent in the air, soluble in sixteen parts of water at 60°, and in its own weight at 212°, and is also soluble in alcohol. A concentrated boiling solution forms, on cooling, almost a firm crystalline mass. Muriate of Morphia is decomposed by diluted sulphuric acid, with disengagement of muriatic acid; strong nitric acid forms a deep-yellow solution with it; spirit of nitric ether slowly communicates a yellow color to its solution; the alkalies, especially potassa, and lime-water precipitate morphia from the solution, but redissolve it when added in excess. Heat, and ses- quichloride of iron affect it in the same manner as they do morphia. Nitrate of silver added to its solution gives rise to a precipitate of chlo- ride of silver. It consists of one equivalent of base 292, one of muriatic acid 36.42, and six of water 54=382.42. According to Christison, the pure salt, dried at 150°, contains 12.7 per cent, of water. Muriate of Morphia prepared by the above process is free from narco- tina or other impurity, and the formula is sufficient for its preparation on a small scale; but when to be manufactured on a large scale, the process of Dr. Wm. Gregory will, probably, be found the most economi- cal, by which a large and pure product may be obtained. By his process, the meconate of morphia existing in the opium is decomposed by chloride of calcium, which forms, through double affinity, a precipi- tate of meconate of lime, leaving muriate of morphia in solution, which is obtained in crystals by evaporation; these are purified by repeated solution, concentration, and crystallization, and lastly decolorization with animal charcoal. It is important to exhaust the opium with as little water as possible, so as to avoid protracted heat while evaporating. Other methods have been advised, but the one above given is sufficient for all practical purposes of the physician or apothecary. White sugar is said to enter into muriate of morphia as an adultera- tion ; it may be detected by the test of fermentation. The principal impurities, however, that are met with, are coloring matter and mois- ture, the result of carelessness in its preparation. According to the Edinburgh College, muriate of morphia should be snow-white, entirely soluble in water, giving a colorless solution; its loss of weight at 212° should not exceed thirteen per cent. ; and one hundred measures of a solution of ten grains in half a fluidounce of water, heated nearly to 212°, and decomposed with agitation by a faint excess of ammonia, should yield a precipitate which in twenty-four hours occupies 12.5 measures of the liquid. Properties and Uses.—Muriate of Morphia possesses properties similar to the other salts of morphia, having essentially all the actions of opium. It is much more extensively used in Great Britain than in this country; and may be employed as a substitute for opium, or the acetate, or sul- phate of morphia. Its dose is from an eighth of a grain to a half; one- sixth of a grain is about equivalent to one grain of opium. A solution of the Muriate of Morphia (Liquor Morphiae Hydrochloras) is made by 72 1138 Pharmacy. dissolving one drachm and a half of Hydrochlorate of Morphia, in a mixture of Rectified Spirit five fluidounces; Distilled Water fifteen fluidounces; aided by a gentle heat. Eighteen minims are equivalent to a grain of opium. The dose is from twenty to forty drops. The alcohol is added to this solution to prevent spontaneous decomposition. Morphia Sulphas. Sulphate of Morphia. Preparation.—Take of Morphia, in powder, an ounce; Distilled Water half a pint; Diluted Sulphuric Acid a, sufficient quantity. Mix the Mor- phia with the Water, then carefully drop in the Acid, constantly stirring till the Morphia is saturated and dissolved. Evaporate the solution by means of a Avater-bath, so that it may crystallize upon cooling. Dry the crystals upon bibulous paper.— U. S. History. — In this process, as soon as the morphia in the water becomes completely dissolved, its saturation is indicated: to determine Avhether there has been an excess of acid added, litmus paper may be employed. The morphia used should be pure; if, however, it contains narcotina, this will remain in the mother-liquor, which generally con- tains a small portion of morphia with impurities, after the first crystal- lization. It should be purified, filtered, and again evaporated to obtain the remainder of the sulphate. It should be observed, that if the heat during evaporation be carried too far, decomposition will ensue, and a new body be formed destitute of morphia. Sulphate of morphia may also be obtained by dissolving the morphia in boiling alcohol of 36° Baume (sp. gr. 0.8428), saturate it with sulphuric acid, while it is hot, add purified animal charcoal, boil for a feAv minutes, and filter the solution while at the boiling temperature. Most of the sulphate is deposited on cooling, and the rest may be procured by evaporation of the mother- liquor. Sulphate of Morphia is obtained in white, mossy tufts or feathery crystals, which are inodorous, bitter to the taste, soluble in cold water, and in twice their weight of boiling water. According to Liebig they consist of 10.33 of sulphuric acid, 75.38 of morphia, and 14.29 of water. A heat of 248° will deprive them of 9.66 parts of their water, but any further loss will occasion decomposition. Their equivalent composition is given as one equivalent of base 292, one of acid 40, and six of Avater 54=386; five equivalents of the latter are water of crystallization, and may be separated by heat. The tests for its purity are those for sul- phuric acid and for morphia. Pure Sulphate of Morphia is readily and entirely soluble in water, and nearly so in alcohol. Properties and Uses.—Sulphate of Morphia is probably more often employed in this country than any other of the salts of this alkali, and is considered to be more uniform in its action on the system. It possesses the usual properties belonging to Morphia and its various salts, and is used in cases where these are indicated. The dose is from an eighth of a Olea Destillata. 1139 grain to a quarter, which may be given in pill or solution. One-sixth of a grain is about an equivalent of one grain of opium. A Solution of Sulphate of Morphia, (Liquor Morphiae Sulphatis,) is made by dissolv- ing eight grains of the Sulphate of Morphia in half a pint of Distilled Water. This forms a convenient solution, in which the morphia may be administered in minute or ordinary doses to suit the occasion; it will keep for a long time unchanged. For an adult the full dose is one or two fluidrachms, which contain from an eighth of a grain to a quarter of the sulphate. Sometimes the sulphate of morphia is not entirely soluble in water, which may be owing to adulterations, but most commonly to the absence of care in its preparation, in which from want of sufficient water to hold the sulphate in solution, crystallization commences before the Avhole of the morphia has been saturated by the sulphuric acid. This difficulty may be overcome by the addition of a few drops of Sul- phuiic Acid, or eight or ten drops of Elixir Vitriol, and a fluidrachm of Alcohol, which Avill render the salt wholly soluble in water. There are other salts of Morphia, as the Nitrate, Phosphate and Tar- trate, prepared as the Acetate, by substituting the respective acids; also the Hydriodate of Morphia, made by mixing together strong solutions of Muriate of Morphia, two parts, and of Iodide of Potassium, rather more than one part. Wash the precipitate with a little Cold Water ; press it between folds of blotting paper, redissolve in Hot Water, and crystallize. Doses of these, same as the Acetate. Iodide of Morphia is obtained by dissolving 120 equivalents of dry Acetate of Morphia in eight times the weight of Cold Distilled Water, adding, if necessary, a few drops of pure Acetic Acid, and mixing the filtered solution with a solution of sixty equivalents of Iodide of Potassium. After some time the salt crystallizes in very slender crystals, but which may be obtained of larger size, by heating the mixture on a water-bath, and allowing it to cool slowly. It closely resembles in form, color, etc., the Sulphate of Quinia. It is insoluble in Cold Water, soluble in Hot Water, and readily in Alcohol; the solutions have a bitter taste. OLEA DESTILLATA. Distilled Oils. For an account of Volatile, Distilled, or Essential Oils, see Olea Vol- atilia, Part II, page 669. The United States Pharmacopoeia gives the following general direc- tions for the preparation of Distilled Oils : " Put the substance from which the Oil is to be extracted into a retort, or other vessel suitable for distillation, and add enough Water to cover it, then distil into a large refrigeratory. Separate the Distilled Oil from the Water which comes over with it. In this manner prepare Oil of Anise from Anise ; Oil of Caraway from Caraway; Oil of Cloves from Cloves; Oil of Wormseed 1140 Pharmacy. from Wormseed; Oil of Cubebs from Cubebs ; Oil of Fennel from Fen- nel Seed ; Oil of Partridge Berry from Partridge Berry Leaves; Oil of Pennyroyal ( Oleum Hedeomoe), from Pennyroyal; Oil of Juniper from Juniper Berries ; Oil of Lavender from Lavender Flowers ; Oil of Pep- permint from Peppermint; Oil of Spearmint from Spearmint; Oil of Horsemint from Horsemint; Oil of Origanum from Origanum, (Marjo- ram) ; Oil of Pimento from Pimento; Oil of Rosemary from Rosemary Tops; Oil of Savine from Savine ; Oil of Sassafras from Bark of Sas- safras Root; and Oil of Valerian from Valerian." To which I will add Oil of Fleabane from Fleabane ; and Oil of Erechthites from Fireweed. The Edinburgh Pharmacopoeia gives the following general directions : " Volatile Oils are obtained chiefly from the Flowers, Leaves, Fruits, Barks, and Roots of Plants, by Distilling them with Water, in which they have been alloAved to macerate for some time. Flowers, Leaves, and Fruits generally yield the finest Oils, and in greatest quantity when they are used fresh. Many, however, answer equally well if they have been preserved by beating them into a pulp with about twice their weight of Muriate of Soda, and keeping the mixture in Avell closed vessels. Substances yielding Volatile Oils must be distilled with Water, the proper proportion of which varies for each article, and for the several qualities of each. In all instances, the quantity must be such as to prevent any of the material from being empyreumatized before the whole Oil is carried over. In operations where the material is of pulpy consistence, other contrivances must be resorted to for the same purpose. These consist chiefly of particular modes of applying Heat, so as to maintain a regu- lated temperature not much above 212°. On the small scale, Heat may be thus conveniently applied by means of a Bath of a strong Solu- tion of Muriate of Lime, or by means of an Oil-Bath, kept at a station- ary temperature with the aid of a thermometer. On the large scale Heat is often applied by means of Steam under regulated pressure. In other operations it is found sufficient to hang the material within the Still in a cage or bag of fine netAvork, and sometimes the material is not mingled with the Water at all, but is subjected to a current of Steam passing through it. The best mode of collecting the Oil is by means of a Refrigeratory, from which the Water and Oil drop together into a tall narrow vessel provided with a lateral tube or lip near the top, and another tube rising from the bottom to about a quarter of an inch below the level of the former. It is evident that with a Re- ceiver of this construction the Water will escape by the lower tube ; while the Volatile Oil, as it accumulates, will be discharged by the upper one, except in the very few instances where the Oil is heavier than Water. By attending to the general principles now explained, Volatile Oils may be readily obtained, of excellent quality, from the Flowers of Anthemis Nobilis, Lavandula Vera and Rula Graveolens; from the Fruit of Anethum Graveolens, bruised; Carum Carui, bruised; Eugenia Olea Destillata. 1141 Pimento, bruised ; Fceniculum Officinale, bruised ; Piper Cubeba, around, and Pimpinella Anisum, ground ; from the undeveloped Dried Flowers of Caryophyllus Aromaticus; from the Tops of Juniperus Sabina, and Ros- marinus Officinalis; from the entire Herb of Mentha Piperita, M. Pule- gium, M. Viridis, and Origanum Majorana; and also from the bruised Root of Sassafras Officinale. The Dublin Pharmacopoeia gives the following officinal directions : " The Volatile or Essential Oils may be obtained by the following general process: The substance from which the Oil is to be extracted is macerated for twenty-four hours, with five times its weight of Water, in a sheet tin, or copper Still, and, a condenser being then attached, half the Water is drawn over by Distillation, on the surface of which the Oil will be found to float, unless (which is rarely the case) it should be heavier than Water, when it will be found at the bottom of the receiA^er. The Oil having been separated, the aqueous product, which is a saturated solution of the Oil in Water, is to be returned to the Still, and the distillation resumed, and continued till the resulting liquid has the same volume as before. The Oil is again separated, the watery pro- duct returned to the Still, and the distillation resumed ; and this process is to be repeated until it ceases to afford any additional Oily product. The Oil thus obtained is to be separated as completely as possible from Water, and preserved in a well-stopped bottle. In this Avay Volatile Oils may be obtained from the entire Herb of Mentha Piperita, Mentha Pulegium, Mentha Viridis; from the Seeds or Fruit of Carum Carui, Cubeba Officinalis, Eugenia Pimenta, Foeniculum Officinale, Juniperus Communis, Myristica Moschata, Pimpinella Ani- sum; from the Flowers of Anthemis Nobilis, Lavandula Vera; from the undeveloped Dried FloAvers of Caryophyllus Aromaticus ; from the Tops of Juniperus Sabina, Rosmarinus Officinalis; from the Bark of Cinna- momum Zeylanicum. The Water distilled over in the preparation of the several Oils should be preserved for medical use." Volatile Oils are contained in cells, generally peculiar, and often so large as to be distinct to the naked eye. They frequently exist in such an abundance, that they may be obtained by mere expression, as with the Oils of Lemon, Orange, Bergamot, and Citron. Sometimes they exude spontaneously or from incisions, in combination with gum or resin, as in the case of Turpentine. And again, the Volatile Oil is not formed in the Plants, until the reaction of Water is obtained upon certain con- stituent principles, as in the case of the Oils of Black Mustard Seed, and Bitter Almonds, and perhaps Peach Leaves, Peach Kernels, etc. Most commonly it adheres with more or less force to the parts of the Plant containing it, either becoming destroyed or dispersed when the Plant is dried or retained in part or altogether, even when long kept. 1142 Pharmacy. Volatile Oils may be obtained from substances either in the Recent or Dried state ; some articles must be used Fresh, from the fact that the Oil becomes lost by drying, as is the case with Roses, Orange Flowers, etc. ; and the greatest yield is obtained from most of the Aromatic Plants by Distilling them while Fresh; though some believe that mode- rate desiccation ensures a larger product. When Dried substances are to be submitted to distillation, they should first be sliced, rasped, shaved, or bruised, according to the character of the agent, and then allowed to macerate in Water, until it has thoroughly penetrated them. Steam Heat is the best for the preparation of Oils, because it is less apt to injure them ; but some Oils will not readily ascend with Steam at 212°, in consequence of which Water saturated with Salt is used, and which does not boil under 230°. It must be recollected that Volatile Oils are injured by Heat, and that in consequence, the temperature of the Heat employed in the Distillation should be as low as may be consistent for the ascent of the Oil. The Water employed in distillation answers a two-fold purpose, that of regulating the Temperature, and thereby preventing the decomposi- tion of the vegetable substance, and also that of facilitating the vola- tilization of the oil, which, though requiring a much higher temperature Avhen distilled alone, yet readily rises with the vapor of water. Some attention, however, must be paid to the quantity of water used, because if in too large a quantity it may hold the oil in solution when the mixed vapors are condensed; and when in very large proportion, no oil what- ever may be obtained separate. Again, if it be too small in quantity, the whole of the oil will not pass over, and the plant, by adhering to the sides of the vessel, will be burnt. More water is required for dried plants than for recent ones, and enough should always be added to cover the whole solid ingredient. The quantity of water together with that of the plant combined, should never exceed three-fourths of the capacity of the alembic, lest the liquor boil over. In cases where the oil is so small in quantity that it becomes dissolved in the water, it is removed by cohobation; a process which consists in redistilling the same water several times from fresh portions of the plant, till the quantity of oil which comes over exceeds the solvent power of the water. As the mixed vapors of oil and water are generally of a milky character when condensed, distillation should be continued as long as this milky appear- ance is observed in the condensed fluid which comes over. The oil is separated from the water by instruments adapted for the purpose, called Separatories, of which there are several in use, known as the Florentine Receiver, Oil-separators, etc. (See Procter's Mohr and Redwood's Phar- macy, pages 351-356.) Volatile oils which have at first an unpleasant empyreumatic odor, should be allowed to remain for a few days in vessels loosely covered Avith paper, or until this peculiar odor has disappeared. They should Olea Destillata. 1143 always he kept in well closed, dark bottles; otherwise they absorb oxygen from the atmosphere, become turbid, deposit resin, and lose the purity and richness of their aroma. These may, in a great measure, be restored by agitating them with animal charcoal recently heated; this will also answer the purpose of freeing them from water, which injures some oils. " The following Table, showing the proportion of Volatile Oil obtained from the chief Medicinal Vegetable Substances, according to the most recent experiments, will be found useful in several ways. Among other things it illustrates several of the general statements now made as to the influence of modes of preparation and circumstances in vegetation upon the quantity of oil. The data are chiefly extracted or calculated from experiments by M. Raybaud in the Journal de Pharmacie, xx.—by Dr. Martius in Reperlorium fur die Pharmacie, xxxix.—by Dr. Bley in the same work, xlviii.—by M. Dann and by M. Voelter in the same work, lv.;—and a few have been added from experiments of my own. The numbers represent the number of ounces obtained from 100 pounds avoirdupois. The experiments of the continental authorities were com- monly made on the large scale. My own were made on a small scale with the apparatus at page vii., and the graduated receiver at page xxxi.; and from a comparative trial in one or two instances upon a large scale, I am disposed to give the preference for accuracy to small opera- tions, when they are carefully conducted.

The facts in the preceding table seem to show that the flowers of Anthe- mis Nobilis, the berries of Juniperus Communis, and the root of Acorus 1146 Pharmacy. Calamus may be both dried and long kept, Avithout material loss of volatile oil; but that the herb of Artemisia Absinthium and the tops of Juniperus Sabina, though they may be dried, cannot be long preserved, without loss. It farther appears that the seed of Sinapis Nigra cannot be long kept without material loss; and that the mace and kernel of Myristica Moschata suffer greatly in their proportion of oil, when attacked by worms. The influence of season is well exemplified in the case of the flowers of Citrus Aurantium, which is well knoAvn to floAver at dif- ferent periods of the year. The effect of climate is equally well shown in many examples, such as the wood of Larix Cedrus, the herb or flow- ering tops of Lavandula Vera, Lavandula, Spica,, Mentha Piperita, Myr- tus Vulgaris, Origanum Majorana,, Rosmarinus Officinalis, Thymus Serpyllum, Thymus Vulgaris, Tanacetum Vulgare, and the seeds of Sinapis Nigra. Under this head, the great superiority of Grasse, in the south of France, over Paris for raising plants for distilling oils, is remark- able. The effect of soil or site is exhibited in my own experiments with the leaves of Laurus Nobilis and Thuya Occidentalis; and that of the progress of vegetation is excellently shown in the instances of the herb of Fceniculum Officinale and Lavandula, Vera, the berries of Juniperus Communis, but above all, the leaves of Prunus Laurocerasus. Farther, the table presents many examples, but especially under Caryophyllus Aro- maticus, Carum Carui, Coriandrum Sativum, and Illicium Anisatum, of great differences prevailing in the relative proportion of volatile oil, and consequently in relative activity, betAveen different specimens of the same vegetable substances as it occurs in ordinary commerce. In con- clusion, it should be observed, that the circumstances most favorable to the proportion of volatile oil are not necessarily always most favorable to its quality. Raybaud mentions, that the cloves of English commerce, which will be seen ( Caryophyllus Aromaticus) from the table to have furnished the lowest proportion of oil, produce it of finer quality than other kinds he examined. And lavender, which yields considerably more volatile oil after flowering than during inflorescence (Lavandula Vera), produces in the latter case an oil of more delicate fragrance than in the former; and it is not so acrid." The above useful information is extracted from Christison's Dispensa- tory, and will, undoubtedly, prove serviceable to the apothecary and manufacturing chemist. As it is sometimes required to know the number- of drops which certain volatile oils yield to a fluidrachm, the following table, extracted from the TJ. S. Dispensatory, and made out by Professor Procter, will be found of some value; although it must be recollected that, as the size and number of drops depend upon the shape of the part from which they fall, these results are only approximative and relative: " The columns of figures represent the number of drops in a fluid drachm of the oils respectively, the first column giving those obtained Olea Destillata. 1147 by dropping the oils from the bottles in which they are commonly kept, the second by dropping them from a minim measure. .......85 86 ... 103 109 .....89 94 ......106 108 " Menthae Vi ......103 103 " Rosmarini .......97 100 ....102 108 102 " Sassafras . ....102 100 96 .....92 111 ......102 103 101 " Valerianae ___116 110 .....95 91 91 Volatile oils possess almost universally the peculiar medicinal pro- perties of the plants from which they are obtained. They are most commonly used in the form of alcoholic tincture, under the name of Essences, but may also be given dropped on a lump of sugar, triturated with ten or twelve times their weight of sugar, forming an oleo-saccha- rum, and then dissolved in water, or they may be made into an emul- sion with water, sugar, and gum Arabic. Oletjm Anisi. Oil of Anise. History.—This may be prepared according to the process of the U. S. Pharmacopoeia; the seed yields, according to various authors, from 1.56 to 3.12 per cent, of oil. The oil is colorless or yellowish, possesses a powerful odor and taste of the seed, and its specific gravity varies from 0.9768 to 0.9903, increasing with its age. At 50° it forms a concrete crystalline mass, and does not melt under 62°. Alcohol of 0.840 dis- solves only 42 per cent, of the oil, but which is readily soluble in alcohol of 0.806. It contains Stearoptene, a principle of volatile oils which is solid at ordinary temperatures, and is heavier than water; and Eleop- tene, another principle, which is fluid and more volatile. Both principles are said to have the same ultimate composition, consisting of ten equiva- lents of carbon, six of hydrogen, and one of oxygen (Cio He O). When long kept the stearoptene becomes liquid, which is oAving to absorption of oxygen from the atmosphere. Spermaceti, wax, or cam- phor is sometimes added to oil of anise as adulterations; they may be known by the odor of the latter, and the insolubility of the former in alcohol. Nearly all the oil used in this country is imported. Properties and Uses.—Carminative and antispasmodic, and especially adapted to flatulency and colic of infants. It likewise, in connection with aqua ammonia, affords relief in spasmodic cough. The dose is from five to fifteen drops. The oil of star aniseed ( Oleum Badiani) has the fla,vor of anise, and is frequently substituted for it. Off. Prep.—Extractum Spigeliae et Sennae Fluidum; Mistura Caju- puti Composita; Tinctura Anisi; Tinctura Opii Camphorata. Oleum Anthemidis. Oil of Chamomile. History.—Oil of Chamomile is obtained by distillation of Chamomile 1148 Pharmacy. Flowers with Water, a thousand parts of which yield about eight parts of oil: when first obtained it is greenish or bluish, but finally becomes yellowish-brown ; its specific gravity is about 0.9083. It has the odor of chamomile flowers, and an aromatic, somewhat pungent taste. It is said to be a mixture of carbo-hydrogen with an oxygenated oil. It is prepared in Europe. Properties and Uses.—Oil of Chamomile is tonic and antispasmodic; and has been found very serviceable in spasm of the stomach, painful dysmenorrhea, hiccough, pertussis, and to prevent or lessen the griping influence of some cathartics. The dose is from five to fifteen drops. The Matricaria Chamomilla furnishes a thick, opake, dark-blue oil, becoming brown and unctuous by age, and which is sometimes used under the name of Oil of Chamomile. It is less antispasmodic than the true chamomile oil. Oleum Bergamii. Oil of Bergamot. History.—Oil of Bergamot is the volatile oil of the rind of the fruit of Citrus Limetta, from which it is procured by expression, in the same manner as for obtaining the oil of lemon. It is imported from Italy, Portugal, and the South of France. It may be obtained by distillation, but the product is not so agreeable as by expression. The bergamot tree has small and white flowers ; oblong-ovate, acute or obtuse, dentate leaves, paler on the under surface, with winged or margined petioles; and the fruit is roundish or pyriform, terminated by an obtuse point, with concave receptacles of oil in the rind; its pulp is acid, rather aro- matic, and pleasant to the taste; its rind is pale-yellow, shininc, abounding in oil. The oil has a peculiar, agreeable, rich fragrance, somewhat resembling oil of lemons but more grateful, a bitter, aro- matic, pungent taste, and a pale greenish-yellow color. Its specific gravity is 0.885, and it may be determined from oils of orange and lemon, by its ready solubility in liquor potassa, forming a clear solution. In composition, it resembles the oil of lemons. Properties and Uses.—Gently excitant; but is used almost exclusively as a perfume. Oleum Cajuputi. Cajeput Oil. History.—This oil is obtained from the leaves of Melaleuca Cajuputi, a tree growing in the Moluccas and neighboring islands, and belonging to the Nat. Ord.—Myrtaceee, Sex. Syst.—Polyadelphia Icosandria. It is a small tree, with an erect but crooked stem, and scattered branches, the slender tAvigs of which droop like those of the weeping willow, (Salix Babylonica). The bark is soft, spongy, lamellated, of a whitish ash color, throwing off its exterior layer from time to time in flakes, like the birch tree. The petioles are short, and the leaves are alternate, lanceo- late, sericeous when young, smooth when full grown, deep green, three and five-nerved, slightly falcate, entire, from three to five inches in Olea Destillata. 1149 length, from one-half to three-quarters of an inch broad, and exhalino- a strong aromatic odor, when bruised. The flowers are small, white, inodorous, sessile, and disposed in terminal and axillary downy spikes, with solitary, lanceolate, three-flowered bracts. The filaments are three or four times longer than the petals, and both are inserted in the rim of the calyx. Cajeput oil is obtained by distillation of the Leaves, which yield it only in small proportion ; this, together with the extensive employment of it in India, renders it a costly article. It is imported from the East Indies in glass bottles. The leaves are collected in the autumn, allowed to steep for a night, and then distilled in copper vessels. The oil is very liquid, transparent, of a grass-green color, a strong penetrating odor partaking both of camphor and of cardamom, and a warm, pungent taste, succeeded by an impression of coolness. Its green color may be removed by rectification, and is not essential; nor is it owing to the presence of copper, as was at one time supposed. True, it sometimes contains copper, but the pure green oil has given no indications of the presence of this metal. Copper may be added to imitate or preserve the green color, but its proportion is so small, as not to interfere with the internal use of the oil; from a pound of the oil of commerce, Guibort procured only two and a half grains of oxide of copper. The copper may be separated from the oil by distillation with water, or by agitation with a solution of ferrocyanuret of potassium. Oil of Cajeput is vola- tile, inflammable, leaving no residue after burning, wholly soluble in alcohol, and of the specific gravity, varying from 0.914 to 0.9274. Sul- phuric and nitric acids exert but little action on it. When distilled, a colorless oil first comes over of sp. gr. 0.897, and then a green oil, denser, Aveaker in odor, but more acrid. It is composed of ten equiva- lents of carbon 60, nine of hydrogen 9, and one of oxygen 8=77. In consequence of its high price it is very subject to adulteration. Oils of rosemary or turpentine, impregnated with camphor and bruised cardamom seeds, and colored with resin of milfoil, are often sold as genuine oil. Zeller considers iodine the best test, the addition of which, reacts moderately energetic, with but a slight increase of temperature, and a faint development of orange-colored vapors, after which inspissa- tion takes place, and soon results in a dry, greenish-brown, brittle mass. The genuine oil, it must be recollected, burns entirely aAvay leaving no residue ; and beside the test above given, copper may be detected by dissolving the residuum which is left after burning the oil in nitric acid, which becomes violet-colored when ammonia is added in excess. Properties and Uses.— Cajeput Oil is a powerful diffusive stimulant, diaphoretic, and antispasmodic. When SAvallowed it occasions a sense of heat, with an increased action of the pulse, and occasionally profuse diaphoresis. It is very much esteemed in the islands of the Indian ocean, the inhabitants of which employ it extensively in rheumatism, palsy, 1150 Pharmacy. epilepsy, and many other diseases; using it both internally and as a local application. It may be advantageously employed internally in chronic rheumatism, hysteria, colic, spasms or cramps of the stomach or bowels, cholera-morbus, Asiatic cholera, in the typhoid stage of fevers, and wherever a powerful stimulant is required. It should never be given internally when inflammation is present. Externally, it is very beneficial as an application to rheumatic, neuralgic, and other pains, and may be used alone, or in combination with other oils. Applied to the cavity of a carious tooth, it relieves toothache. The dose is from one to ten drops, on sugar, or in emulsion. Off. Prep.—Mistura Cajuputi Composita ; Mistura Olei Camphorata ; Tinctura Camphorae Composita. Oleum Cari. Oleum Carui. Oil of Caraway. History.—This oil is easily separated by distillation of the fresh fruit with water, which yields on an average about 4.7 per cent. It is at first pale-yellow, but becomes brownish by time, possesses the odor of the fruit, with an aromatic acrid taste. Its specific gravity is variously given as 0.946 and 0.931. It consists principally of a hydro-carbon, Cio Hs, Carvene, and an oxygenated oil, Carvacrol. When Oil of Caraway is distilled with hydrated phosphoric acid, the distilled liquor being poured back into the retort until it ceases to have the smell of caraway, an oily liquid separates from the phosphoric acid, having a very disagreeable odor, and a strong taste, which is called Carvacrol. Or, if a saturated solution of iodine be distilled with Oil of Caraway, until no more hydriodic acid is formed, a red mass will be formed in the retort. This must be acted upon by potassa, and the yellow solution distilled. Carvene passes over, and the Carvacrol remains ; this must be purified by redistillation. Properties and Uses.—Oil of Caraway is a warm diffusible stimulant and carminative. It is frequently used to correct the griping and nau- seating effects of medicines, also to increase their flavor. It is consid- erably used in cake and confectionary. The dose is from one to five or ten drops. Carvacrol placed on cotton, and inserted into the cavity of a carious tooth, is said to give immediate relief. Off. Prep.—Extractum Spigelian et Sennas Fluidum. Oleum Caryophylli. Oil of Cloves. History.—Oil of Cloves is procured by distillation of bruised cloves with water, to which salt is usually added to increase the temperature; the cloves should be thoroughly exhausted by repeatedly distilling from the same cloves the water which comes over. Good cloves yield from a fifth to a sixth of their weight of oil. Formerly, the oil was imported from Europe or the East Indies, but at present, it is prepared in this country from the Cayenne cloves, seven to nine parts of which yield one part of oil. Olea Destillata. 1151 When first obtained, oil of cloves is very fluid, transparent, and color- less, but gradually becomes yellowish, and finally reddish-brown. It has the strong, peculiar odor of cloves, and an aromatic, intensely acrid, burning taste. It sinks in water, in which it is sparingly soluble, and is completely soluble in alcohol, ether, acetic acid, and the fixed oils. Its specific gravity is between 1.034 and 1.061. Nitric acid changes it to a deep-red, and forms oxalic acid by the application of heat. It is less volatile than most of the other essential oils, and congeals only at —4° F. It deposits a crystalline stearoptene on long standing. It consists of two oils, one of which is lighter than water, the other heavier. They may be separated by distilling the crude oil from a solution of potassa, the light, colorless oil passes over with the watery vapor; its density is 0.918, consists of, carbon and hydrogen, and is isomeric with pure oil of turpentine, Cio H?. It is said to be destitute of active properties. The heavier oil remains in union with the potassa, from which it may be ob- tained by the addition of sulphuric acid, and then distilling. It is like- wise colorless, but becomes darker by age, possesses the peculiar odor and taste of cloves, boils at 470°, is of the specific gravity 1.079, forms soluble and crystallizable salts with the alkalies, earths, and oxides of the common metals, and is hence called Eugenic or Caryophyllic Acid. It is composed of C24 His Oo. The crude oil of cloves consists of carbon 20, hydrogen 12, oxygen 5. Oil of cloves is frequently adulterated with fixed oils, oil of pimento, and copaiba. It may be detected by observing that the pure oil sinks in distilled water. Zeller states that its purity may be known by its congealing into a crystalline mass with the alcoholic solution of potassa, at the same time being deprived of its peculiar odor. Properties and Uses. — Oil of Cloves is stimulant and irritant, and is much used as a corrector of other medicines, and as an external counter- irritant. It is frequently introduced on cotton into the cavity of a carious tooth to relieve toothache. Its dose is from two to six drops on sugar, or in emulsion. Off. Prep.—Mistura Cajuputi Composita; Mistura Olei Camphorata; Pilulae Aloes Compositae. Oleum Chenopodii. Oil of Wormseed. History. — Oil of Wormseed is prepared in this country; that which is procured from manufacturers in the vicinity of Baltimore is the most esteemed. It is obtained by distillation of the bruised seed or ripe tops of the plant with water, and when first obtained is of a light yellow color, but becomes darker by age. It possesses the odor and taste of the plant, and has the specific gravity of 0.908. An oil of less strength is pre- pared in the Western States from the leaves, stalks, and seed of the matured plant, and, probably, possesses similar properties when given in larger doses. That from the seeds always commands the highest price. 1152 Pharmacy. Properties and Uses.—This oil is used only as an anthelmintic. Its dose is from four to eight drops for a child, repeated tAvice a day for three or four days, and then followed by a brisk cathartic. It forms the basis of several popular nostrums for worms. Off. Prep.—Mistura Chenopodii Composita; Mistura Olei Composita. Oleum Cinnamomi. Oil of Cinnamon. History.—Oil of Cinnamon is obtained by macerating coarsely pow- dered Cinnamon Bark for two days in Sea Water, adding Muriate of Soda, and then distilling. About one-third of the oil which comes over is light and floats upon the Water, Avhile the rest sinks, and this sepa- ration of the two oils continues for several days. The Water used in the distillation being saturated Avith the Oil, is reserved for future distil- lations. Cinnamon Bark yields about eight ounces of oil from eighty pounds, and even less, if the bark be a few years old. The two oils procured by the distillation, differ, apparently, only in density; and in the oil of commerce they are probably united. When freshly prepared Oil of Cinnamon is of a light yellow-color, which gradually changes to cherry-red. It has the odor of cinnamon, and also its taste in a concen- trated state. It is readily soluble in alcohol, and has the specific gravity varying from 1.035 to 1.041. Exposed to the air, it absorbs oxygen, and deposits colorless, sourish, volatilizable crystals, which are soluble in alcohol, sparingly so in water, and which may be converted into ben- zoic acid by the action of nitric acid and heat; these crystals are called Cinnamic or Cinnamonic Acid, and may be frequently observed in bottles which have held the oil for a long time. When taken internally, these crystals give rise to the presence of hippuric acid in the urine, the same as villi benzoic acid. Two distinct resins and water, are also the result of exposure to atmospheric action; one of these resins is soluble in hot alcohol, but sparingly in cold, while the other is soluble in either. Concentrated nitric acid, added very gradually to oil of cinnamon to aAroid violent action, converts it speedily into a mass of crystalline scales, which are considered to be a compound of the oil and acid. Cinnamyle (Cis Ht Os ) is the name given to a hypothetical compound radical of oil of cinnamon, which forms oil of cinnamon by uniting with one equiv- alent of hydrogen, and anhydrous cinnamic acid, Avhen united with one equivalent of oxygen. Oil of Cassia, or Chinese Oil of Cinnamon, very much resembles the Ceylon oil in color, odor, and taste; the latter, however, is inferior. It is sold at a much less price than the Ceylon Oil of Cinnamon. The chemical reactions of the two oils are the same. Zeller states that they differ somewhat, the Chinese oil being heavier than the Ceylon, less liquid, and sooner rendered turbid by a decrease of temperature; that iodine dissolves rapidly in the latter, with increase of heat, and the pro- duction of a tough residue or extract, while in the Cassia oil its solution is quiet, slow, with little heat, and a soft or liquid residue. Olea Destillatta. 1153 Properties and Uses.—Oil of Cinnamon is stimulant, aromatic, anti- spasmodic, and carminative. It is frequently used to correct the taste of medicines, and is given as a stimulant in flatulent colic, gastrodynia, and languor from gastric debility. It undoubtedly exerts an influence upon the uterus, and will be found valuable in uterine hemorrhage, in the form of alcoholic tincture. The tincture of the bark is frequently adminis- tered for this purpose, but I know from experience, that although desti- tute of astringency, yet the tincture or essence of the oil has the same, if not a better action, in such cases; again, it is an unsafe remedy to exhibit during pregnancy, as it is very apt to produce miscarriage. The essence, or even cordial of cinnamon, stimulates the generative organs, and produces an aphrodisiac influence. The dose of oil of cinnamon is one or two drops, given in emulsion ; of the essence from half a fluidrachm to a fluidrachm, given in a wineglass of sweetened water. Ten drops of oil of cinnamon added to a fluidrachm of olive oil, gently heated, and rubbed upon the spine, will frequently quiet a restless, fretful child suffering with flatulence or colic, and cause it to sleep ; if the rubefacient power requires to be increased, ten drops of aqua ammonia may be added. Oleum Copaiba. Oil of Copaiba. Preparation. — Take of Copaiba two pounds; Water four gallons. Add the Copaiba to the Water in a tinned still, and, having adapted a proper refrigeratory, distil three gallons. Separate the Oil which comes over from the Water, return the latter to the Copaiba, and again distil three gallons. Lastly, separate the Oil obtained in the second distilla- tion, add to it that first obtained, and keep the whole in a well stopped bottle.—ET. S. History.—The more recent the Copaiba the greater is the amount of vob'le oil obtained. Usually about one-third or one-half of the Copaiba is procured in oil, and it is stated that one specimen yielded 80 per cent. The oil has the taste and odor of copaiba, is colorless, or pale-yellow, according to the variety of copaiba employed, has the specific gravity of 0.910, boils at about 470°, and is very soluble in alcohol and ether. It forms crystals of artificial camphor by absorption of muriatic acid gas, is composed of carbon 10, hydrogen 8, being isomeric with pure oil of turpentine. It is considered a better preservative of potassium than naphtha, on account of its entire freedom from oxygen. It is best pre- pared by steam heat. The fine greenish colored oil which comes over during the latter part of the distillation, may be rendered colorless by redistillation. Properties and Uses.—The Oil of Copaiba exerts an influence upon the system, similar to that of copaiba, to which it is preferred on account of the smaller dose required, and its non-tendency to cause nausea. It enters into many of the nostrums of the day for the cure of gonorrhea. 73 1154 Pharmacy. The dose is ten or fifteen drops, Avhich should be given in syrup, pep- permint or cinnamon water, mucilage, or emulsion. Oleum Cubebae. Oil of Cubebs. History. — Cubebs ground, and distilled with water, furnish about seven per cent, of this oil. It is a thick, colorless oil, but as commonly met with has a greenish or yellowish tint. It possesses the peculiar taste and odor of the berries, is lighter than water, being of specific gravity 0.929, and thickens on exposure to the air without being deprived of its odor; occasionally it deposits crystals, which are supposed to be a hydrate of the oil. It is composed of carbon and hydrogen, C15 H12. Properties and Uses.—Oil of Cubebs may be substituted for the pow- derd berries, in many instances, with benefit. It is less pungent than the oleo-resin or fluid extract, and is, probably, only one of the active principles of cubebs. The dose is ten or twelve drops, three times a day, gradually increased, as the stomach will permit, or until it produces some decided results. It may be given in syrup, emulsion, or in the form of capsules, like copaiba. Oleum Erechthiti. Oil of Fireweed. History.—This oil is obtained by distilling the plant Erechthites Hiera- cifolius Avith water. As obtained in the shops, it is quite fluid, trans- parent, yelloAvish in color, of a strong, peculiar, fetid and slightly aromatic odor, and a fetid, bitterish, burning taste. In its odor and taste it somewhat resembles the Oil of Fleabane. It is soluble in alco- hol. No analysis has been made of it. Properties and Uses.—The therapeutical actions of Oil of Fireweed are not well understood. It seems to resemble the Oil of Fleabane in its influence upon various hemorrhages, and for which agent it is fre- quently substituted ; and is considered by many to be the most effica- cious, in such cases, of the two oils. It also exerts a beneficial effect on mucous surfaces, and has been successfully used in diarrhea, dysentery, hemorrhoids, etc. As an antispasmodic it has been found of value in spasms of the stomach and bowels, colic, hiccough, hysteria, and per- tussis. It is chiefly employed for the same purposes as the oil of flea- bane. The dose is from five to twenty drops on sugar, or in emulsion. When triturated with the extract of stramonium, oil of fireweed is said to form a valuable preparation for piles. Oleum Erigeroni. Oil of Fleabane. History.—This is obtained by distillation of the Leaves and Flowers of Fleabane Avith Water. When first obtained it is said to be of a light yellow color, and transparent. The specimen which I have before me is about six years old, it is quite fluid, of a wine-red color, clear, with a peculiar, rather pleasant, aromatic, mint-like odor, and an aromatic, bitterish, not very agreeable, penetrating taste ; both the odor and taste Olea Destillata. 1155 recall to mind those of oil of spearmint, combined with oil of amber. The only change I have noticed in the oil in my possession is a deposit of a reddish color, resembling currant jelly, soft, tenacious, in flat or tabular scales or crystals, and which I have not had an opportunity of analyzing. This deposit burns when brought into contact with flame, giving off a dense smoke, with an odor resembling that of cedar. The oil has not been analyzed. Properties and Uses. — Oil of Fleabane is stimulant and carminative, with scarcely any perceptible astringency. It appears, notwithstanding, to exert a very remarkable influence on the system in hemorrhages, to check which, it is chiefly used. It is said to be of superior value in all hemorrhages, but more especially when from the uterus. Further in- vestigations with this remedy are required, in order to know its proper therapeutical actions. The dose is from two to ten drops, dissolved in alcohol, and administered in mucilage or sweetened water. Combined with five or six parts of Castor Oil, or of Stramonium Ointment, it forms a valuable application to piles. (For further uses, see Erigeron Cana- dense, part II, page 450.) Oleum Fceniculi. Oil of Fennel. History.—Oil of Fennel is prepared from Fennel seeds, by distillation with water; it is colorless or pale-yellow, possesses the peculiar taste and odor of the seeds, is crystallizable at 50°, and has a specific gravity of 0.997 to 0.999. The seeds yield about 2.5 per cent, of volatile oil. The oil contains Stearoptene and Eleoptene, the former of which is iden- tical in composition with that obtained from oil of anise. It consists of carbon 13 equivalents, hydrogen 8 and oxygen 2. The oil employed in this country is imported, but is not very uniform in its character, and which is supposed by some to be owing to its being the product of different plants or species. One specimen examined by Dr. Montgomery, remained fluid at 22°. Properties and Uses.—Oil of Fennel is principally used as a carmina- tive, and for the purpose of correcting or concealing the unpleasantness of other medicines. The dose is from five to twenty drops. Oleum Gaultheria. Oil of Wintergreen. History. — Oil of Wintergreen is prepared by distilling the plant with water; when first procured it is nearly colorless, but becomes more or less of a deep-yellow or red color by age. It has a peculiar and agree- able odor, and a SAveetish, somewhat pungent, peculiar taste. Its specific gravity is 1.173, being the heaviest of the essential oils, and it boils at 412°. It possesses acid qualities, and has, according to Cahours, the same composition as the salicylate of methylene. Its purity may be determined by its unusual weight. The greater part of the oil used in this country, is prepared in New Jersey. 1156 Pharmacy. This oil is not peculiar to the Gaultheria alone, but has been detected in the bark of Betula Lenta, the root of Polygala Paucifolia, and the stems and roots of Spirwa Ulmaria, Spiroza Lobata, and Gaultheria Hispidula. Properties and Uses.—This oil is stimulant and aromatic, and is princi- pally employed to correct or disguise the taste of other medicines. The essence, or the oil dissolved in alcohol is stated to have been found effectual in curing intermittent fever. The dose of the oil is from five to ten or fifteen drops on sugar, or in emulsion. Oleum Hedeomoe. Oil of Pennyroyal. History.—This oil is obtained from the Pennyroyal plant of this coun- try, by distillation with water. It is of a light-yellow color, with the agreeable odor of the plant, and its warm, pungent taste, and has the specific gravity 0.948. Properties and Uses.—Oil of Pennyroyal is a stimulant, carminative, antispasmodic, and emmenagogue. It has been used with benefit in cramp of the stomach, flatulent colic, nausea, amenorrhea, and to diminish the harshness of griping, as well as nauseating medicines. It is frequently employed for the purpose of occasioning abortion, but as with all agents of this sort, it is very dangerous. It is sometimes applied externally as a mild rubefacient. The dose is from two to ten drops on sugar, or in emulsion. Oleum Juniperi. Oil of Juniper. History.—Oil of Juniper is procured from the bruised berries by dis- tillation with Avater ; it may likewise be procured from the leaves. It is nearly colorless, or pale greenish-yellow, lighter than water, being of the specific gravity 0.911, has a turpentine odor, a warm, pungent taste, and is not perfectly soluble in alcohol. The oil is imported into this couptry from Europe, and is, probably, a mixture of that from the berries and leaves. Like pure oil of Turpentine it consists of ten equivalents of carbon, and eight of hydrogen ; but does not become solid with muri- atic acid. The fraudulent addition of oil of turpentine, which frequently occurs, may be knoAvn by the specific gravity of the mixture being much less than that of the pure oil of Juniper. Properties and Uses. — Oil of Juniper is stimulant, carminative, and diuretic, and is frequently employed to arrest chronic mucous discharges, especially from the urethra. It may also be used in cases of dropsy as a diuretic, combined with other agents. The dose is from five to fifteen or twenty drops. The peculiar flavor and diuretic property of Holland gin is owing to the presence of this oil. Off. Prep.—Pilulae Saponi Compositae. Oleum Juniperi Virginiana. Oil of Cedar. History.—This oil is prepared by distillation of the tops and leaves of Red Cedar with Water. It is quite fluid, transparent, of a light yellow- Olea Destillata. 1157 ish or reddish color, but becoming of a wine-red color by age, possesses the peculiar odor, with the nauseous, bitterish, warm taste peculiar to the leaves, in a concentrated degree. Upon standing, but very little deposit ensues ; in a specimen before me of sixteen years' standing, and about a pint in quantity, can be observed a very slight deposit of con- fluent whitish granules or scales, somewhat resembling white wax. Properties and Uses.—Internally this oil is stimulant and emmena- gogue, possessing properties similar to those of the oil of savin; however, it is very seldom administered internally. It is chiefly used as a rube- facient, and forms an excellent local application in inflammatory rheu- matism and other painful affections, either alone or combined Avith other articles to form a liniment. The dose, internally, is from two to ten drops, on sugar. Off. Prep.—Linimentum Olei. Oleum Lavandula. Oil of Lavender. History.—Oil of Lavender is procured from the flowers of Lavender, by distillation with Water; the commercial oil is generally prepared from the flowers and flower-stems. The dried flowers yield from 1 to 1.5 per cent, of oil. Oil of lavender is of a pale-yellow color, a pure, grate- ful, lavender odor, and a bitter, aromatic, camphoraceous taste. Its specific gravity varies from 0.893 to 0.948. Berzelius states that at 68° F., the commercial oil has the specific gravity 0.898, which, upon rectification, is reduced to 0.877. The oil prepared by distilling the whole herb, has the sp. gr. 0.920. It is soluble in all proportions in alcohol of 0.830, in two parts of proof spirit, and incompletely in acetic acid. Upon exposure to the air, it absorbs oxygen to the amount of about 120 volumes in four months and a half. It consists of a fluid oil or Eleoptene, and a solid substance or Stearoptene, the latter of which is isomeric with laurel-camphor. The broad lea\Ted variety of lavender, Lavandula Spica, furnishes the Oil of Spike, it is not so fragrant as the preceding oil, and bears some analogy to oil of turpentine. It is chiefly used in the preparation of varnishes for artists. Properties and Uses.—Oil of Lavender possesses stimulant and car- minative properties, and is sometimes administered in hysteria, nervous debility and headache. Its fragrance renders it an important article in perfumery, in which it is principally used. The dose of it is from one to five drops. Off. Prep.—Tinctura Lavandulae Composita. Oleum Limonis. Oil of Lemons. History.—Oil of Lemon is obtained by lightly grating the fresh rind of the lemon, placing it in a fine cloth-bag, and then submitting it to pressure ; the sediment is allowed to settle, and the clear oil is poured off. It may 1158 Pharmacy. also be procured by distillation,, but being, when thus made, less fragrant, the method by expression is preferred. The oil is imported from the southern parts of Europe, as Italy, Portugal, etc. It is of a pale-yellow color, but may be rendered colorless by distilla- tion, has a rich lemon odor, a warm, aromatic, penetrating taste, and is very volatile. Its specific gravity is 0.8517, but is reduced to 0.847, by distillation of about three-fifths of it. In pure or anhydrous alcohol it dissolves in all proportions, and is soluble in seven or eight parts of ordinary alcohol. The pure oil is isomeric with pure oil of turpentine, consisting of ten equivalents of carbon, and eight of hydrogen, and forms by absorption of muriatic acid gas a sblid substance of a crystal- line character, and an oily fuming liquid of a yellow color. The solid substance is composed of one equivalent of oil, and one of acid, and is analogous to the artificial camphor formed from oil of turpentine, the latter of which has the formula C20 Hi6, HC1, while that from the lemons is C20 H8, HC1. When cooled to 8° F., oil of lemon deposits some crystals, and when exposed to the air it absorbs oxygen. It is frequently adulterated by alcohol, the fixed oils, or more fre- quently by oil of turpentine. Alcohol may be detected by the milky fluid which forms upon agitating the oil with water. The fixed oils may be known by leaving a permanent stain upon paper, which is not the case with the genuine oil. Oil of turpentine may be detected by the turpentine odor evolved when the impure oil is evaporated from heated paper. M. Biott states that the camphor formed by the oil of lemons exercises no action on polarized light, while the oil itself rotates a ray to the right. On the contrary, the camphor from oil of turpentine exer- cises a power similar to that possessed by the isolated oil, of rotating to the left. These molecular properties establish a difference between the two oils, and may serve to detect adulteration and fraud. In order to remove mucilaginous and other matters existing in the oil of lemons, it is recommended by J. S. Cobb, to agitate the oil with a little boiling water, and to allow the Avater to remain in the bottle. A mucilaginous mixture forms on the top of the water, and acquires a cer- tain tenacity, so that the oil may be poured off nearly to the last, without disturbing the deposit. The gradual decomposition of the oil, he sup- poses to be owing to the presence of these impurities, which enter during the process of expression and decantation. He recommends that the oil, as well as all other essential oils, should be kept in a cool, dark place, where no very great changes of temperature occur. Properties and Uses.—Stimulant and aromatic. Its chief use is in per- fumery, and to impart a pleasant flavor to medicines. It has been recommended in certain cases of ophthalmia, as a local application. A very agreeable drink for the summer and for febrile patients may be made of White Sugar four ounces, Oil of Lemon ten drops, triturate together, and add Citric Acid tAvo drachms; a teaspoonful of this to a Olea Destillata. 1159 tumbler of water forms a pleasant, refreshing draught. Tartaric acid may be substituted for the citric, if desired. Oleum Mentha Piperita. Oil of Peppermint. History. — Oil of Peppermint is obtained by distilling the herb with water; which yields from the 170th to the 300th part of the oil. When fresh it is nearly colorless, or pale greenish-yellow, but becomes darker and even reddish by age. It has the strong aromatic odor of the plant, together with its warm, pungent, camphorous taste, is of the specific gravity from 0.902 to 0.920, and is soluble in alcohol. When taken into the mouth and air admitted, a sense of coolness is produced. At 365° it boils, and at—8° it deposits fine needle-like crystals of Stearoptene, which is said to have the same composition as the oil; these crystals are also deposited at ordinary temperatures, on long standing. The compo- sition of the oil is C21 H23 O2. Its adulterations with alcohol and oil of turpentine are not infrequent; the latter may be detected by its imper- fect solubility in cold alcohol, its odor, and its disposition to explode when iodine is added; the former may be known by the dirty-Avhite liquor formed by adding an equal volume of water to it. The oil is extensively manufactured in this country. Properties and Uses. — Oil of Peppermint is a powerful diffusible stimulant, with carminative, antispasmodic, and anti-emetic properties. It is much employed to relieve flatulence, gastrodynia, nausea, spasms of the stomach and bowels, and to cover the taste of other drugs. Externally, it is occasionally employed as a rubefacient. It enters into a liniment, which at one time was a popular remedy for various painful local affections; it is composed as follows: Take of Oil of Olives, Oil of Peppermint, Oil of Turpentine, Tincture of Opium, Alcohol, Aqua Ammonia, each, one fluidounce; mix. To be applied three or four times a day. It is commonly used under the name of Essence of Pep- permint, which is a tincture of it. The dose of the oil is five or ten drops on sugar. Off.

Oil of Horsemint. History.—Oil of Horsemint is extensively manufactured in this country from the fresh herb, by distillation with water. It is of a reddish-yellow, or brownish color, of a strong, aromatic odor, a hot, pungent, even acrid taste, and is soluble in alcohol. It is composed of a yellowish-red fluid, Eleoptene, which has the odor of thyme, and passes over, when distilled with water, of a bright-yellow color—and of Stearoptene, which forms in large crystalline fragments, having the odor and taste of the oil, and for which the name of Monardin has been proposed. The oil has not been accurately analyzed. Properties and Uses.—Oil of Horsemint is stimulant, antispasmodic, and anti-emetic, and in the form of the essence, has been much used to allay nausea and vomiting in Asiatic cholera, cholera-morbus, etc., its action in these cases being prompt and permanent. The dose of the oil is from two to five drops on sugar; of the essence, from ten to thirty drops in sweetened water. Externally, it is rubefacient and even vesi- cant, and has been advantageously used in low forms of fever, cholera- infantum, paralysis, rheumatic and neuralgic pains, etc. It soon causes heat, redness, and pain when locally applied, affording in many instances almost immediate relief. Oleum Origani. Oil of Origanum. History.—This oil is obtained from the Origanum Vulgare, by distilla- tion of the plant with water; about from four to six parts of oil are pro- cured from a thousand parts of the plant. It is of a yellow color, Avhich becomes reddish by age; too much heat during the distillation will also give it a reddish color. Its odor is the same as that of the plant, and its taste hot and acrid; it boils at 354°, is soluble in alcohol, has its specific gravity varying according to several chemists, being given as 0.867, 0.909, and 0.940, and its composition is represented by Cso Hto 0. It is imported from Europe, and is commonly adulterated with oil of tur- pentine. Much of the oil of origanum sold in this country is said to be the oil of thyme, which is prepared from the Thymus Vulgaris in the South of France. The Oil of Sweet Marjoram obtained from the Origanum Majorana by distillation, in the proportion of from two and a half to six parts from a thousand of the plant, is of a lemon-yellow color, light and camphora- ceous, and forms a deposit similar to camphor. It is seldom employed in the United States. Properties and Uses.—Oil of Origanum is stimulant and rubefacient, and is chiefly employed in the form of liniment as an application to Olea Destillata. 1161 various parts suffering from painful affections. As with many other essen- tial oils, it affords relief in toothache upon being introduced into the cavity of the carious tooth, on lint or cotton. It is very seldom adminis- tered internally. Off.

History.—When Pimento Berries are bruised and distilled with water, they yield from one to nearly five per cent, of an oil, having the odor of the berries, and a hot, pungent taste. When recent it is colorless or yellowish, but becomes brownish-red by age. Its specific gravity is given as 1.021, but it is variable. Nitric Acid added to it, turns it red. Like the Oil of Cloves, it unites with salifiable bases, and also consists of a light oil and a heavy oil. When distilled with a solution of caustic potassa, the light oil comes over, and the heavy, which remains behind in combination with the potassa, may be obtained separately by distilling it with Sulphuric Acid. The light oil is a pure carbohydrogen ; the heavy forms crystalline bodies with the alkalies ; these oils are nearly similar to the light and heavy oils of cloves. Properties and Uses.—Oil of Pimento is stimulant and aromatic, and may be used for similar purposes as other oils of like character, in doses of from three to six drops. Off. Prep.—Aqua Pimentae. Oleum Rosa. Oil, or Otto of Roses. History.—Oil of Roses is prepared in Egypt, Persia, and other Asiatic countries, by distilling the petals of Rosa Centifolia, Rosa Damascena, Rosa Moschata, and some other species, with Water. It is obtained in very small quantity, not exceeding three drachms of the oil from a hundred pounds of the petals. It is a very high priced oil, and is gen- erally imported in small vials or bottles. The manufacturing season is in March and April. It is also said to be obtained by bruising the petals in a mill, express- ing, filtering the expressed fluid, then placing it in small glass vessels, and exposing it to the sun ; as the oil gradually rises to the surface, it is removed. Notwithstanding the Oil of Roses is prepared in the Eastern kingdoms, it has not been obtained to any degree in Europe or America. Oil of Roses is at first of a greenish tint, but subsequently presents various shades of green, yellow, or red ; but the color is no criterion of its quality. It has an agreeable, intense, most penetrating and diffusive odor, concretes below 80°, becomes liquid at or above 84°, and has the specific Gravity, at 90°, of 0.832. It dissolves in about 150 parts of alcohol. It consists of carbon 23, hydrogen 23, and oxygen 3. Two oils enter into its composition, a Fluid Oil, Eleoptene, consisting of 1162 Pharmacy. carbon, hydrogen, and oxygen, and a Concrete Oil, Stearoptene, consisting only of carbon and hydrogen. By pressing the Oil of Roses between folds of blotting paper, the Eleoptene is absorbed, while the Stearoptene remains. Owing to its high price, Oil of Roses is very subject to adulteration with the Oil of Sandal Wood, other volatile oils, fixed oils, spermaceti, etc. In those specimens adulterated with volatile oils, they may be known by not concreting at ordinary temperatures ; and those to which fixed oils are added, leave a greasy stain on heated blotting paper. Properties and Uses.—Oil of Roses is used altogether as a perfume, and is frequentl}" added to cerates, ointments, liquors, etc., for the pur- pose of rendering them fragrant. Off. Prep.—Aquae Rosae. Oleum Rosmarini. Oil of Rosemary. History. — When the fresh Leaves of Rosemary are distilled with Water, they yield from a half to one per cent, of Oil, which is colorless, of specific gravity 0.911, soluble in Alcohol of 0.830, and possesses the odor of the Plant. Its boiling point is stated by Kane, to be 365°, its specific gravity 0.897, and its combination C45 H38 O2. When rectified its sp. gr. is reduced to 0.8886 ; and at 64° it requires forty parts of Alcohol 0.887 for solution. Exposed to the air a portion of it evapo- rates, and a Stearoptene, somewhat analogous to Camphor, is left, amounting to about a sixteenth of the original weight of the Oil. It is stated that by digesting the Oil Avith its weight, or one-half its weight of Potassa, and distilling, Camphor will be obtained. Oil of Rosemary is frequently adulterated with Oil of Turpentine; the adulteration may be detected by adding to the suspected Oil an equal volume of Alcohol, which dissolves the Oil of Rosemary, but leaves the Oil of Turpentine. Properties and Uses.—Oil of Rosemary is stimulant and rubefacient; it is principally employed, however, in perfumery. A very pleasant Cologne may be made as follows : Take of Oil of Rosemary, Oil of Lemon, each, two fluidrachms ; Oil of Lavender, Oil of Bergamot, of each, one fluidrachm ; Oil of Cinnamon, Oil of Cloves, Oil of Roses, of each, eight minims; Alcohol one pint. Mix, agitate well, and after allowing the mixture to stand for a few days, with frequent agitation, filter. The dose of Oil of Rosemary is from three to six drops. Off. Prep.—Linimentum Opii; Linimentum Saponis Camphoratum. Oleum Ruta. Oil of Rue. History.—The fresh Leaves and Tops of Rue, when Distilled with Water, yield about seven grains in the thousand of a yellowish, acrid, heavy-smelling Volatile Oil, having the pure, intense, penetrating odor of the Plant, of specific gravity 0.837, and boiling at 446°. It becomes gradually brown with age. Its composition is given as C28 H23 O3. Olea Destillata. 1163 Properties and Uses.—Oil of Rue is stimulant, antispasmodic, and em- menagogue. It has been used with advantage in hysteria, convulsions, pertussis, amenorrhea, and dysmenorrhea, in the dose of from tAvo to five drops, three times a day. It is sometimes criminally used for the purpose of producing abortion, in which it is highly dangerous, having been folloAved by fatal consequences. Oleum Sabina. Oil of Savin. History.—When the Tops and Leaves of Savin are submitted to dis- tillation with Water, they yield a yelloAvish, clear Oil, having in an intense degree the peculiar odor of the Leaves, and a bitter, acrid taste. The proportions of Oil obtained, as given by authors, vary very much, being stated at from one to sixteen per cent. Its specific gravity is stated to be 0.915, and its boiling point 315. It is isomeric with Oil of Turpentine, being a pure hydro-carbon, composed of ten equivalents of Carbon, and eight of Hydrogen. Sulphuric Acid added to it, will, it is asserted, convert it into an Oil very analogous to Oil of Thyme. Properties and Uses.—Oil of Savin is stimulant, emmenagogue, and rubefacient ; and may be administered in all cases as a substitute for the plant. It has been found especially valuable in amenorrhea. Ten drops of the oil on sugar, repeated three times a day, will, it is stated, positively produce abortion in from one to three weeks ; but as with all other agents of this kind, it is apt to be followed by very serious conse- quences. The dose of the Oil, ordinarily, is from two to five drops. Off. Prep.—Tinctura Caulophylli Composita. Oleum Sassafras. Oil of Sassafras. History.—The Bark of the Root of Sassafras, when submitted to dis- tillation with Water, yields from two to three per cent, of a heaA'y Vola- atile Oil, having the specific gravity 1.094. When first procured it is colorless or pale-yellow but gradually acquires a reddish tint. It has the peculiar and agreeable fragrance of Sassafras, and a hot, penetrating, aromatic taste. It is said to be composed of two Oils, one of which sinks in Water, while the other floats; but according to Berzelius, the latter is frequently nothing more than Oil of Turpentine, which has been added as an adulteration. Sassafras Oil becomes reddened by Nitric Acid, and most readily inflames when fuming Nitric Acid is added to it; Caoutchouc placed in it, is dissolved after a short time. Exposed to the air without agitation it deposits crystals of Stearoptene, which possess the odor of Sassafras, and are transparent. Properties and Uses.—Sassafras Oil is stimulant, diuretic, carmina- tive, alterative, and diaphoretic. It may be used for all the purposes for Avhich the bark is recommended. It is said to be an efficacious appli- cation to wens. It is much used as a local application to rheumatic and other pains. The dose is from two to ten drops on sugar, or in emulsion. 1164 Pharmacy.

Rectified Oil of Amber Preparation.—Take of Oil of Amber a pint; Water six 2>ints. Mix them in a glass retort, and distil until four pints of the Water shall have passed with the Oil into the receiver ; then separate the Oil from the Water, and keep it in well stopped bottles.— U. S. History.—The Oil of Amber, thus rectified, is sufficiently pure for practical purposes, yet it may be procured thinner, more limpid, and col- orless by several successive distillations. As ordinarily found, it is of an amber, or light yelloAvish-brown color, with a peculiar, powerful, disa- greeable odor, and a warm, acrid taste. It is soluble in eight parts of alcohol of sp. gr. 0.847 at 55°, in five parts of the sp. gr. 0.825, and in all proportions in absolute alcohol. It unites with fixed oils, and imparts its taste and odor to water, without any apparent solution. The pure oil has the specific gravity 0.758 at 75°, and boils at 186°. Exposed to the light and air, it gradually changes its color and consistence, until it finally becomes black and solid. One hundred parts of it contain 88.46 parts of carbon, and 11.54 of hydrogen. The crude Oil of Amber is prepared as folloAvs : Put any quantity of Powdered Amber, previously mixed with an equal weight of Sand, into a glass retort, which is to be only half filled; then distil, by means of a sand-bath, with a gradually increasing heat, an acid liquor, an oil, and a concrete acid impregnated with oil. Separate the oil from the other matters, and keep it in well-stopped bottles.— U S. In this process, the amber becomes decomposed, and yields, beside other matters, thick, very dark-colored, empyreumatic oil, which floats upon the surface of an acid liquor in the receiver. The addition of the sand is to prevent the amber from SAvelling too much. The oil may be separated from the acid liquor by means of a separating funnel. When the object is to decompose all the amber for the purpose of procuring as much oil as it will yield, the process of distillation should be carried on in a tubulated iron, or earthenware retort, as one of glass cannot support the requisite heat. Properties and Uses.—Rectified Oil of Amber is the only form in which the oil of amber should be employed for internal use. It is stimulant, diuretic, and antispasmodic ; and has been employed with benefit in amenorrhea, hysteria, dysmenorrhea, tetanus, epilepsy, pertussis, infan- tile convulsions, and various other spasmodic affections. The dose is from five to thirty drops on sugar, repeated as often as required. Ap- plied externally it is a rubefacient, and has been efficaciously used as a liniment in palsy, chronic rheumatism, pertussis, and infantile convul- sions ; in the latter affection it should be rubbed along the spine, either Pilula. 1165 alone, or combined with an equal part of laudanum and three or four parts of olive oil.

It is of a greenish-yellow color, with the flavor of the plant, and deposits camphor upon standing. Properties and Uses. — Oil of Tansy possesses the properties of the plant, but is seldom employed internally on account of its bitterness. It has been employed to produce abortion, but almost always with fatal results. Dose of the oil, from two to five drops. Oleum Valeriana. Oil of Valerian. History.—When the root of Valeriana Officinalis is distilled with Water, it yields rather more than one per cent, of a pale-greenish volatile oil, of the specific gravity 0.934, possessing a powerful, penetrating valerian odor, and a warm, aromatic taste ; and which becomes viscid and yellow, when exposed to the air. It is a compound substance of a peculiar nature, containing a carbohydrogen, equivalent in composition with pure oil of turpentine, a minute quantity of stearoptene, possessing an odor resembling that of pepper and camphor, an oxygenated oil called Valerol, ( C20 H12 O ) which is changed into valeric or valerianic acid by the action of the air, and a small proportion of valerianic acid, which, however, is increased by exposure to the atmosphere. Properties and Uses.—Oil of Valerian possesses the properties of the root in a concentrated degree, and may be substituted for it, in all cases where the root is applicable. It has been found especially useful in hys- teria, chorea, restlessness, etc. An efficacious preparation for nervous, sleepless and hysterical cases is composed of: Tincture of Lupulin, Tincture of Hyoscyamus, of each, four fluidounces; Camphor, one drachm ; and Oil of Valerian, twenty-two minims. Mix, and give one or two fluidrachms for a dose. The dose of the oil of valerian is four or five drops. PILULE. Pills. Pills are a very convenient mode of administering medicines which are in any way unpleasant, which are insoluble in water, or which do not require to be given in large doses. There is, probably, no form in which medicines are more frequently administered, than that of the Pill; and to make a good Pill-mass requires considerable knowledge, tact, and judo-ment on the part of the operator. The points demanded to prepare 1166 Pharmacy. a proper pill mass, are to obtain sufficient consistency, that the particles may cohere together, and to have them firm enough to retain the glob- ular form; their component parts should be such as to prevent any ten- dency to moldiness, or any absorption of moisture when exposed to the atmosphere. Medicines which are deliquescent, should not be made into pills, and efflorescent substances should first be deprived of their water of crystallization. Neither should ingredients be added together which exert a mutual reaction upon each other ; though this is frequently done, perhaps, to secure th% influence of the resulting formation. Many articles admit of being made into pills at once, having sufficient consistence for that purpose, as with soft extracts, and some gum-resins ; or, the addition of a little water to the former, or a few drops of alcohol to the latter, will impart to them the necessary degree of softness and plasticity, should they require it. Substances which do not admit of being made into a pill mass by themselves, must have certain inert mat- ters added to them, called excipients; and such excipients only should be employed as will give the proper degree of consistence and tenacity to the mass, Avithout interfering in any way with the action of its medi- cinal agents, or rendering the pills too large or hard. Excipients vary very much in their character, according to the nature of the articles to be made into pill form ; the most common are, syrup, mucilage, soap, bread-crumb, conserve of roses, water, spirit, gum, sugar, magnesia, starch, molasses, etc. The dry, inert poAvders of starch, bread-crumb, flour, gum arabic, etc., are incorporated with soft or liquid substances as extracts, confections, soap, oils, syrup, molasses, honey, mucilage, etc. The softer articles are combined with hard, dry, or not readily soluble agents ; and among these molasses, and conserve of roses are the most esteemed, especially when the pills are to be kept for any length of time. The addition of too much gum arabic, or tragacanth to the pill mass, is objectionable, as it often causes the pill to become so hard as to have its operation materially modified, or perhaps, causing it to pass through the intestines without being dissolved. Whenever the excipient is named by the physician in his prescription, the apothecary should adopt it if practicable; but, if it be not practicable, then he must follow his own judgment. Indeed, it would always be better in prescribing extempo- raneous preparations of pills, if the physician would omit the excipient, and leave it to the more practical knowledge of the apothecary to supply. The best excipients for dry powders, as jalap, rhubarb, ipecacuanha, ginger, digitalis, conium, etc, are molasses or conserve of roses; those for resinous extracts, resins, and gum-resins, are soap, proof-spirit, alka- line solutions, and sometimes mucilage ; and those for the volatile oils and oleo-resins, are soap, magnesia, white wax, etc. The proper selec- tion of these, however, depends entirely upon the peculiar nature of the medicines ordered, and requires a considerable degree of practical knowledge, not expected to be possessed by the practicing physician. Pilula. 1167 The medicinal ingredients of the pill should be accurately mixed together, and then the excipient, in most cases, must be added, and the whole beat in a mortar, till a mass of perfect uniformity and plasticity is formed; care being taken that the pills are not made so hard as to resist the solvent power of the fluids of the stomach. The mass, havino- been properly prepared, is rolled into cylinders of precisely the same thick- ness throughout, and of a length depending upon the number of pills to be made, and is then divided, as equally as possible, into the requisite quantity of pills. This is sometimes done by means of a spatula, the spherical form being given by rolling the pills between the fingers ; but most apothecaries are furnished with pill-machines, which serve to expedite the process, as well as to secure a greater degree of accuracy. A new pill-machine has been lately patented by a Mr. Lewis, which is said to be superior to any other yet used. " It consists of two metallic cylinders or rollers, having on their surface a series of hemispherical indentations or cups, corresponding in shape and size to half a pill, so that when the rollers are brought into contact side by side, and a rotary motion given them, the hemispheres in each fall immediately and accu- rately opposite each other, forming a series of spherical molds, in which, during the process, the pills are cast. The arrangement for working the rollers consists of tAvo uprights, in and between which they are fixed side by side so as to revolve on their axles. Motion is communicated by means of a handle attached to a small pinion, fitting a cog-wheel at the side of one of the rollers, at the other side of which is another cog-wheel fitting a corresponding one on the other roller; these being accurately adjusted cause each other to revolve with equal speed so as always to bring the hemispheres opposite each other. The pill mass is introduced, by means of a small hopper, between the two rollers while in motion, and as from their being in close contact it cannot pass through, it is pressed into the hemispheres, and the pills are thus formed, which are collected from the outer sides of the rollers as they continue to revolve. Thus far the simple plan of making or casting pills by means of a rotatory machine, with minor modifications, has been before attempted, but as frequently abandoned from the pills remaining firmly imbedded in the hemispheres of one or other of the rollers, and the want of contrivance to deliver them freely, without the necessity for detaching them with the hand. That difficulty, in the present machine, is entirely overcome, and this achieArement is its principal claim to originality and practical utility. The arrangement by which this long-sought desideratum is accomplished, consists of a movable bolt or pin at the bottom of each hemisphere, which, acted upon by springs at the interior of the rollers, forces out the pills, and detaches them effectually from the mold in which they have been cast. The only point of adhesion is now the end of the pin, from Avhich they generally fall by their OAvn inert gravity; but to prevent the possibility of their being drawn back again into the hemi- 1168 Pharmacy. spheres by the return of the pins to their original position, they are gently lifted off by being carried between the teeth of a sort of rake pressing against the outside of the rollers. Some of the pills thus formed have a slight rim round them, giving them the appearance of a seed or berry, but in every other respect they are perfect; they may, therefore, be left in their original state, or subjected to the usual process of mulling. From this machine, which had only two bands or tiers of hemispheres round the rollers, about 150 pills might be turned out in a minute, or 9000 in an hour, working it very slowly. There would be no difficulty in doubling the speed of working, and the rapidity of making might be multiplied by increasing the number of molds or hemispheres on the rollers." Several years ago, I saw a pattern machine upon a somewhat similar principle, but much more simple and perfect in its arrangement and action, the invention of Mr. Semple of this city, which would turn out about six hundred pills in a minute; and it is to be regretted that he has been so much occupied since, as to lay aside his valuable invention. In order to prevent the pills from adhering to each other, or to the sides of the vessels in which they are kept, it is usual to agitate them in some dry powder, Avhich gives them an external covering, as well as conceals their taste. For this purpose, powdered elm bark, powdered liquorice root, carbonate of magnesia, and starch are employed; starch is almost too light, carbonate of magnesia may be incompatible with one or more of the ingredients of the pills, and the liquorice root, or elm bark, Avill, as a general rule, be found the best. In Europe the powder of Lycopodium is much employed; and in former times it was customary to coat the pills with silver or gold leaf. It has recently been proposed by M. Garotto cover pills with gelatin, which answers the purpose of concealing their taste, without interfering with their solubility in the stomach. He dips each pill, sustained on the point of a pin, into melted gelatin, withdraws it with a rotary motion, then fixes the pin in a paste so as to allow the coating to dry in the air, and having prepared about fifty pills in this way, proceeds to complete the operation by holding the pin in the flame of a taper so as to melt the gelatin near its point, and then withdraAving it from the pill so as to close up the orifice. The purest glue should be selected for this purpose, melted Avith the addition of tAvo or three drachms of water to an ounce of the glue, and kept in the liquid state by means of a salt-bath. A coating of collodion has also been recommended, but this is improper, as the collodion will not readily dissolve in the stomach; also a mixture of equal parts of gum-arabic, sugar and starch, in poAvder; the pills to be dipped in a thin syrup, and then rolled in the mixture. This process is most applicable to disagreeably odorous substances, as castor, assafetida, valerian, etc., which are completely masked by it. When the gelatin is previously colored with carmine, the pills resemble hawthorn berries. Pilula. 1169 M. Calloud treats of the subject of enveloping medicinal substances in a covering to prevent unpleasant taste, in Journal de Pharmacie XXIII, 301. After having tried gum, starch and sugar without satis- faction, owing to the hygroscopic tendency of the sugar and gum in moist air or with a moist mass, and their tendency to crack when very dry, he had recourse to the dried mucilage of flaxseed prepared with sugar, with success. His method is,—take of flaxseed one part, white sugar three parts, spring-water a sufficient quantity. A thick mucilage is obtained by carefully boiling the seeds, the sugar is added, and the whole of the moisture evaporated by careful desiccation. This mixture is but very slightly hygroscopic, may be reduced to fine powder, and employed for covering pills. This operation is effected extemporaneously with great facility. The pills slightly moistened, are rolled in the muci- laginous powder, by which they are coated with a layer of the compound. He has used this chiefly for carbonate of iron pills, but it maybe applied to other kinds. M. Calloud suggests another process applicable in certain cases, which is the use of butter of cacao as a covering for pills, where owing to gastric irritation, the unmasked pills will cause disagreeable symptoms. The process is very simple ; the prepared pills are thrown into melted butter of cacao, then removed with a perforated skimmer, and finally rolled in finely powdered sugar, or what is better, sugar of milk. Pills are much better preserved in small glass bottles, than in the common wood or pasteboard boxes. Pilula Aconiti Composita. Compound Pills of Aconite.

Preparation.—Take of Camphor, Opium, Kino, of each, in powder, thirty grains; Capsicum five grains; Conserve of Roses a sufficient quan- tity. Mix together and form a pill mass, and divide into thirty pills. Properties and Uses.—These pills were much employed in Asiatic cholera, as a stimulant, antispasmodic, anodyne, and astringent, and Pilula. 1171 with much success. One pill to be given after each discharo-e from the bowels, or oftener, if the urgency of the case require it. Where pow- ders are preferred, the conserve of roses may be omitted, and the mix- ture be given in powder.—R. S. N. Pilula Cimicifuga Composita. Compound Pills of Black Cohosh. Preparation.—Take of the Hydro-alcoholic Extracts of Black Cohosh, and Scullcap, each, one drachm; Valerianate of Quinia half a drachm. Mix thoroughly together, form into a pill mass, and divide into sixty pills. Properties and Uses.—These pills will be found very useful in chorea, and other derangements of the nervous system; also in fevers or other diseases, attended with much restlessness or wakefulness, and in several uterine affections. The dose is one pill every one, two, or three hours, daily, according to the urgency of the symptoms.—J. K. Pilula Copaiba. Pills of Copaiba. Preparation.—Take of Copaiba and White Wax, of each, one drachm. Melt the Wax, mix in the Copaiba, and divide into thirty pills. These pills are frequently combined in other proportions, and with the addition of Cubebs. Thus: take of Copaiba one part; White Wax one part and a half; Cubebs, in powder, two parts. Melt the Wax, add the Copaiba and Cubebs, and divide into four-grain pills. This combination is suitable to warm climates. Another combination is: take of Copaiba one part; White Wax two parts ; Cubebs, in powder, three parts. Pre- pare as above, and divide into four-grain pills. Properties and Uses.—These pills are useful in gonorrhea, and other affections where the medicinal agents are indicated. The dose is two to four pills, three times a day. Copaiba is usually solidified into a pill mass by the use of magnesia. The magnesia combines with the hard resin or copaibic acid, and absorbs the volatile oil, in consequence of which the copaiba gradually loses its fluidity, becoming at first a soft, tenacious mass, and finally dry, hard, and brittle. The proportion of magnesia required to solidify the copaiba, depends entirely upon its proportions of volatile oil and hard resin. Ordinarily, about one-sixteenth part of magnesia will be found to solidify the copaiba of the shops in six or eight hours. One advantage in this preparation is, that the copaiba is made into a pilular condition, with but little increase of its bulk. Care should be taken to divide the mass into pills before it becomes too hard, and that the magnesia employed has not become hydrated by exposure to a moist air or otherwise. M. Thierry states that if one part of freshly prepared hydrate of lime be mixed in a marble mortar with fifteen parts of copaiba, the mixture then transferred to an open vessel, placed upon a sand-bath, and the heat be kept up for four hours, occasionally stirring, it will produce the same effect as magnesia. About a twenty-fourth of the weight of the mixture is lost, which is chiefly the water of the hydrate. 1172 Pharmacy. Pilula Copaiba Composita. Compound Pills of Copaiba. Preparation.—Take of Solidified Copaiba one drachm ; Ethereal Ex- tract of Cubebs half a drachm; Podophyllin nine grains; Gum Myrrh one drachm; Alcoholic Extract of Nux Vomica fifteen grains. Mix thoroughly together, and divide into three-grain pills. Properties and Uses.—These pills are useful in gonorrhea, gleet, stric- ture, and chronic inflammation of the prostate. The dose is from two to four pills, twice a day. For ordinary cases, the following preparation will be found beneficial: Take of Solidified Copaiba two drachms; Ethereal Extract of Cubebs one drachm; Oil of Juniper a sufficient quantity, not to impair the pilular consistency of the mass. Mix, and divide into pills of four grains each. The dose is the same as above. Pilula Eupurpurini Composita. Compound Pills of Eupurpurin. Preparation. — Take of Eupurpurin two scruples; Xanthoxylin one scruple ; Strychnia one grain. Mix thoroughly together, and divide into twenty pills. Properties and Uses.—This forms a stimulating diuretic, and will be found useful in suppression of urine, torpor or paralysis of the kidneys or bladder, rheumatism, hepatic torpor, derangements of the digestive functions, etc. The dose is one pill, to be repeated three or four times a day.—J. K. Pilula Ferri Carbonatis. Pills of Carbonate of Iron. Vallet's Ferruginous Pills. Preparation.—Take of Sulphate of Iron eight ounces; Carbonate of Soda ten ounces; Clarified Honey three ounces; Sugar, in powder, two ounces; Boiling Water two pints; Syrup a sufficient quantity. Dissolve the Sulphate of Iron, and Carbonate of Soda, each separately, in a pint of the Water, having previously added a fluidounce of Syrup to each pint; then mix the two solutions when cold, in a bottle just large enough to hold them, close it accurately with a stopper, and set it by, that the Carbonate of Iron may subside. Pour off the supernatant liquid, and having washed the precipitate with Warm Water sweetened with Syrup, in the proportion of a fluidounce of the latter to a pint of the former, until the washings no longer have a saline taste, place it upon a flannel cloth, to drain, and express as much of the Water as possible ; then immediately mix the precipitate with the Honey and Sugar, and by means of a water-bath evaporate the mixture, constantly stirring, until it is so far concentrated as to have a pilular consistence on cooling.— U. S. History.—In the above preparation, the carbonate of iron, which by the ordinary processes, absorbs oxygen and loses a great proportion of its carbonic acid while washing and drying, is, by the saccharine matter employed throughout the operation, almost completely prevented from such injurious change. And to preserve the ferruginous preparation Pilula. 1173 unaltered for medicinal use, it is evaporated to a pilular consistence, with the addition of Honey and Sugar, as related in the formula. If the sul- phate of iron used should be impure, a portion of sesquioxide will cer- tainly be present. When properly prepared, this is in a soft mass, of pilular consistence, black throughout, of a strong, chalybeate taste, and wholly and readily soluble in acids. Properties and Uses.—This pill is a ferruginous tonic, and may be employed in all cases where iron is indicated. It is especially useful in chlorosis, amenorrhea, and other female complaints; by its use the color- ing matter of the blood seems to be increased, and the capillary system rendered more active. It may be divided into pills varying from three to five grains each, of which from three to six may be given per day, and continued for several weeks, particularly if an improvement of the health takes place. Pilula Ferri Composita. Compound Pills of Iron. Emmenagogue Pills. Preparation.—Take of Subcarbonate of Iron one drachm; Podophyl- lin fifteen grains; White Turpentine half a drachm. Mix well together, and divide into thirty pills. Properties and Uses.—This pill is used chiefly as an emmenagogue. The dose is one pill every three or four hours. Pilula Ferri Ferrocyanureti Composita. Compound Pills of Ferrocyanuret of Iron. Preparation.—Take of Ferrocyanuret of Iron, Sulphate of Quinia, and Hydro-alcoholic Extract of Black Cohosh, each, two scruples. Mix, and divide into forty pills. Properties and Uses.—These pills are tonic, alterative, and antiperi- odic, and may be used in all diseases attended with periodicity, as inter- mittent fever, chorea, epilepsy, etc. They will be found an excellent remedial agent. The dose is one pill, three or four times a day, or oftener if required.—J. K. Pilula Ferri Iodidi. Pills of Iodide of Iron. Preparation.—Take of Sulphate of Iron a drachm ; Iodide of Potas- sium four scruples ; Tragacanth, in powder, ten grains; Sugar, in pow- der, half a drachm. Beat the articles with Syrup so as to form a mass, to be divided into forty pills.— U. S. History.—By the above process, a double decomposition takes place ; the sulphuric acid of the crystallized sulphate of protoxide of iron com- bines with the potassium to form sulphate of potassa, while at the same time the iodine forms with the iron an iodide of iron. Consequently the pill will contain sulphate of potassa; and also a portion of iodide of potassium, this salt being added in a greater quantity than is required 1174 Pharmacy. to decompose all the sulphate of iron. The sulphate and iodide are to be first rubbed together, and when accurately mixed, the sugar and tragacanth must be added, and then the syrup. By the addition of the sugar, the iodide of iron is protected from oxidation. This pill should never be kept or made, except for immediate use. It is not very tenacious in its character, and at first evolves iodine ; it has a styptic, rather acrid taste, but is not so unpleasant as the Solution of Iodide of Iron. The presence of sulphate of potassa and iodide of potassium renders it complex and objectionable. Properties and Uses.—This pill has the same therapeutical applica- tions as the solution of iodide of iron. Each pill contains a little more than a grain and a half of iodide of iron; one of which may be given for a dose, and repeated two or three times a day. In consequence of the intensely styptic taste of the solution of iodide of iron, as well as the disagreeable stain it imparts to the teeth and lips, a serious inconvenience has arisen in its administration, and many modes have been devised to divest it of these objections, as well as of its ten- dency to change. Perhaps the best mode of preparing it, is the following: Take of pure Iodine, Iron reduced by Hydrogen, each, half a drachm; Honey, a sufficient quantity to give the consistency of thick molasses. Triturate the Iodine as finely as possible, then add the Iron and Honey, and continue the trituration until the articles are thoroughly mixed together, and fumes of iodine cease to be disengaged, the mixture assuming a greenish tinge. Then rub in finely powdered Extract of Liquorice, a sufficient quantity to make the mass. After the pills have been made, for still further protection from atmospheric influence, they may be dipped once or twice in an ethereal solution of Balsam of Tolu. Pilula Hyoscyami Composita. Compound Pills of Hyoscyamus. Preparation.—Take of Extract of Hyoscyamus, Extract of Valerian, each, two drachms ; Extract of Aconite, Sulphate of Quinia, of each, one drachm. Mix thoroughly together, and divide into pills of three grains each. Properties and Uses. — These pills will be found advantageous in neuralgia, rheumatism, chorea, dysmenorrhea, and many affections of a similar character. The dose is one pill every two, three, or four hours, according to circumstances. As the virtue of Valerian resides in its oil, it is probable the extract is nearly useless ;■ and one-half the quantity of the Oil of Valerian, or Valerianic Acid, could be substituted for the extract, and form a much more efficacious pill.—/. K. Pilula Leonuri Composita. Compound Pills of Motherwort. Preparation.—Take of the Hydro-alcoholic Extracts of Motherwort, and Unicorn Root, each, two drachms ; Leptandrin, Cimicifugin, of each, cm,e drachm. Mix thoroughly together, form a pill mass, and divide into sixty pills. Pilula. 1175 Properties and Uses.—These pills are useful in many uterine affections, acting as a uterine tonic and alterative. One pill may be given every one, two, or four hours, according to the urgency of the case.__J. K. Pilula Leptandrini Composita. Compound Pills of Leptandrin. Preparation.—Take of Leptandrin one drachm ; Podophyllin half a drachm; Extract of Rhubarb a sufficient quantity. Mix together, and divide into sixty pills. Some prefer making these pills with Extract of Dandelion, instead of Rhubarb. Properties and Uses.—This is a valuable cholagogue pill, very benefi- cial in liver affections, obstinate constipation, or wherever catharsis is required. It will likewise be found useful in dysentery. The dose is from one to three pills, once or twice a day. Pilula Phytolacca Composita. Compound Pills of Poke. Preparation.—Take of Extract of Poke two drachms; Hydro-alco- holic Extract of Stillingia one drachm; Extract of Stramonium eight grains. Mix thoroughly together, form into a pill mass, and divide into sixty-four pills. Properties and Uses.—These pills will be found of value in osteoco- pus, or pains in the bones of a mercurial or syphilitic character, and are also beneficial in rheumatism, syphilis, and scrofula. The dose is one pill every two, three, or four hours, as the urgency of the case may require. The fluid Extract of Stillingia, may be substituted for the Hydro-alcoholic Extract, and pulverized Poke-root added as an exci- pient.—J. K. Pilula Podophyllini Composita. Compound Pills of Podophyllin. Preparation.—Take of Podophyllin, Scammony, Gamboge, each, in powder, one drachm; Castile Soap half a drachm. Triturate the pow- ders thoroughly together for about half an hour, then add the Soap ; mix and beat the whole together till they are thoroughly incorporated. Divide the mass into one hundred and twenty pills. Properties and Uses.—This is a most valuable pill for all diseases where cathartics are required, and has cured many cases of hepatic affections by a continued use of them. The dose is one or two pills, every night. They have no tendency toward producing constipation, but rather the reverse, and after using them for several days in succes- sion, thejr will generally be found so active that it will be necessary to omit them for a number of days, before resuming their administration. They may be safely used in all ordinary cases where purgation is desired ; they operate freely and thoroughly, and usually without causing nausea, griping, or debility. In consequence of the difficulty with which pure Scammony is obtained in this country, many practitioners substitute for it, in these pills, Apocynin, or Extract of Rhubarb, or Iridin, either of which, 1176 Pharmacy. will, probably, be found preferable to an impure or counterfeit scam- mony.—J. K. Pilula Polygoni Composita. Compound Pills of Water Pepper. Preparation.—Take of Dried Sulphate of Iron, and Cimicifugin, each, one drachm ; Iridin fifteen grains ; Extract of Water-Pepper a sufficient quantity. Mix well together, and divide into sixty pills. Properties and Uses.—These pills are emmenagogue, and exert an especial influence on the female organs of generation. They have been used with advantage in chlorosis, amenorrhea, dysmenorrhea, uterine leucorrhea, etc. The dose is one pill every two or three hours.—J. K. Pilula Pteleini Composita. Compound Pills of Ptelein. Preparation. — Take of Hydrastin, Cimicifugin, Ptelein, Aletridin, of each, half a drachm; Alcoholic Extract of Nux Vomica four grains. Mix the articles thoroughly together, and divide into sixty pills. Properties and Uses.—These pills are very efficacious in dyspepsia, attended with distress after eating, flatulency, etc. They act upon the mucous coat of the stomach, gradually restoring it to a normal condi- tion. I have employed them considerably, and prefer them to any other remedy which I have ever used. If constipation be present, it must be removed by rhubarb and potassa, podophyllin, or other proper agents. The dose is one pill three times a day, to be taken about an hour after each meal, with the proper attention to diet and regimen.—J. K. Pilula Quinia Sulphatis. Pills of Sulphate of Quinia. Preparation. — Take of Sulphate of Quinia one drachm; Aromatic Sulphuric Acid fortyfive drops. Drop the Acid into the Quinia on a tile or slab, and triturate with a spatula until it assumes a pilular consist- ence ; then divide into sixty pills. History.—This method of forming Quinia into a pill mass was made known by Mr. E. Parrish. The ingredients when mixed form a fluid, which soon thickens into a paste, and finally becomes quite solid, and so adhesive as to be readily divided and rolled into pills; care must be taken not to allow the mass to become too dry and brittle before dividing it, as it is liable to do if allowed to remain too long. In this form a por- tion of the disulphate being converted into the soluble neutral sulphate, the preparation more nearly resembles the solutions in composition, and is believed to be more certain and rapid in its action. When it is desired to incorporate other substances in powder with the Quinia thus prepared, as Prussiate of Iron, etc., they should be added to the mass when it is just so soft that, upon their addition, it will immediately assume the proper consistence. It is not, hoAvever, advisable to employ this process when any considerable quantity of other ingredients are prescribed with the quinia, unless a little syrup or honey is also added to prevent the too rapid hardening and consequent crumbling of the mass. Pilula. 1177 Properties and Uses.—For the uses of these pills, see Sulphate of Quinia. Each pill contains a grain of sulphate of quinia, and twelve are equivalent to an ounce of good Peruvian Bark. The above pill mass, may be made into five-grain pills if desired, which will not be found inconveniently large. Pilula Quinia Composita. Compound Pills of Quinia. Preparation.— Take of Sulphate of Quinia, Cornine, and Tartaric Acid, each, in powder, one drachm,; Hydro-alcoholic Extract of Black Cohosh a sufficient quantity. Mix together, and divide into four-grain pills. Properties and Uses.—These pills are tonic and antiperiodic, and may be employed in intermittent and remittent fevers, and in all diseases attended with symptoms of periodicity. The addition of the tartaric acid renders the quinia more readily soluble in the juices of the stomach. The dose is one pill every one, two, or three hours, according to the severity or urgency of the symptoms.—J. K. Pilula Saponi Composita. Compound Pills of Soap. Diuretic Pills. Preparation. — Take of Oils of Spearmint, Juniper, and Sassafras, each, one fluidrachm; Castile Soap one drachm and a half. Beat the Soap in an iron mortar, gradually adding the Oils, and when the ingre- dients are thoroughly incorporated, divide into eighteen pills. Properties and Uses.—These pills are stimulant and diuretic, and are very beneficial in gravel and all chronic urinary affections. The dose is three pills three times a day, or one pill every hour through the day.— T. V. M. Pilula Taraxaci Composita. Compound Pills of Dandelion. Preparation.—Take of Bloodroot, in powder, one drachm,; Podophyl- lin half a scruple; Extract of Dandelion one drachm; Oil of Spearmint five minims. Mix the Powders with the Extract, add the Oil, beat up thoroughly together, and divide into fifty pills. Properties and Uses.—Laxative, nauseant, and diuretic. They are of much efficacy in jaundice, hepatic diseases, and affections of the kid- nevs. The dose is one or two pills three times a day, sufficient to pro- duce a slight sensation of nausea. This pill is superior to the one made after the old formula.—T. V. M. Pilula Valeriana Composita. Compound Pills of Valerian. Preparation.—Take of the Hydro-alcoholic Extract of Scullcap, and Extract of Chamomile, each, two drachms ; Extract of Boneset, Sulphate of Quinia, of each, one drachm; Capsicum one scruple; Oil of Valerian half a drachm, by weight. Mix the articles together, beat them until thoroughly incorporated, and divide into ninety pills. 1178 Pharmacy. Properties and Uses.—These pills are tonic and nervine, and may be used in all cases where such a combination of action is desired. The dose is one pill every two or three hours. Pilula Viburni Composita. Compound Pills of High Cranberry. Preparation.—Take of Hydro-alcoholic Extracts of High Cranberry, Blue Cohosh, and Unicorn Root, each, half a drachm ; Extract of Par- tridge Berry one drachm. Mix together, and divide into forty Pills. Properties and Uses.—These pills are of superior efficacy in uterine diseases, as amenorrhea, dysmenorrhea, leucorrhea, etc. ; as a uterine tonic in habitual miscarriages ; and may be given during pregnancy to relieve cramps, and many other unpleasant sensations occurring at that period. The dose is one or two pills three times a day.—J K. POTASSA. Preparations of Potassa. Potassa. Potassa Hydras. Caustic Potassa. Hydrate of Potassa. Preparation.—Take of Solution of Potassa a, gallon. Evaporate the Water in a clean iron vessel over the fire, till ebullition ceases, and the Potassa melts. Pour this into suitable molds, and keep it, when cold, in well stopped bottles.— U S. History. — The Solution of Potassa used in preparing this Caustic, should be one of recent manufacture, and the evaporation should be con- ducted in an iron vessel, as glass or earthenware are acted on by the potassa ; and in using an iron vessel, hoAvever clean it may be, a small portion of Oxide- of Iron will be imparted to the caustic, but not in quantity sufficient to interfere Avith its medicinal applications. The con- tact of all organic substances should be carefully avoided. The evapo- ration must be completed as speedily as possible, so as to lessen the liability to absorption of carbonic acid from the atmosphere. Absorption of carbonic acid will not take place, so long as the temperature is kept at the boiling point; but if the evaporation be in any way interrupted, and the liquid alloAA-ed to cool, the potassa becomes quickly carbonated. The molds into which the fused potassa is run, should be made of iron, and having a cylindrical shape. As white flint glass is slightly acted on by the caustic alkali, it should be kept in green glass bottles with ground stoppers. Potassa, as met Avith in the shops, is either in the form of fragments of plates, or in cylindrical pencils of a dingy gray or greenish color, with sometimes a bluish tint, a fibrous fracture, an intense, corrosive, alkaline taste, and an odor similar to that of slaking lime. It is exceed- ingly deliquescent, powerfully attracting carbonic acid from the atmo- sphere, and when moist feels soapy. It is readily soluble in water or alcohol, its aqueous solution having the properties of Liquor Potassa. Potassa. 1179 Acids combine with it, causing much heat, and forming crystallizable salts. It melts at a low-red heat, and is volatilized at a bright-red heat. It usually contains many impurities, as sesquioxide of lime, silica, sul- phate of potassa, alumina, chloride and teroxide of potassium, carbonate of potassa, etc. By dissolving it in alcohol, which does not act upon these impurities, but takes up only the pure hydrated potassa, filtering and evaporating to dryness, and then fusing the dry mass obtained, a pure hydrate of potassa may be procured, white, dry, hard, brittle, and intensely caustic. This is called Alcoholic Potassa, and possesses pro- perties similar to the impure article above described. When i*s solution is added to an excess of tartaric acid, it yields a crystalline precipitate of cream of tartar, and when added to a solution of chloride of platinum, a yelloAv precipitate is the result; and which actions will serve to detect it from soda and lithia. Independent of its impurities, the officinal potassa consists of one equivalent of dry potassa 47.2, and one of water 9=56.2. Dry potassa consists of one equivalent of potassium 39.2, and one of oxygen 8=47.2. Properties and Uses.—Caustic Potassa is powerfully corrosive; when applied to soft animal textures, it first attracts their water, and then rapidly disorganizes them; after Avhich extensive inflammation ensues around the part, previous to the separation of a deep slough. It has no action as a poison, except what depends directly on the local injury occasioned; no direct influence being exerted through the medium of absorption. Acids, as vinegar, lemon-juice, etc., and the fixed oils are antidotes to its injurious action, producing with it harmless salts of potassa or soapy solutions. It is administered internally only when in solution, as an antacid, anti- lithic, and diuretic. Externally, it is used, in its solid state, for making caustic issues, opening abscesses, and destroying tumors, but from its extreme deliquescence, it is very apt to spread, and act on parts not desired. To obviate this the integuments around the parts to be acted on, should be protected by two or three layers of cloth, spread Avith adhesive plaster, and perforated with a hole in the center, of the neces- sary size. Then a rod of potassa, slightly moistened at the end, is to be gently rubbed over that portion of the skin embraced in the perforation of the plaster. It must be rubbed until the skin becomes discolored, when an elm, or bread-and-milk poultice must be applied. In a few days the eschar will be detached. After the slough separates, the retraction of the surrounding skin always makes the surface of the issue much larger than the circle originally cauterized, the extent of which must be regulated accordingly. In applying the caustic, Avrap it Avith paper. We occasionally employ this caustic in the destruction of tumors, cancers, etc., and on the surface of unhealthy or malignant ulcers. A very unscientific application of a solution of this caustic, applied to the spine, has been recommended in the treatment of tetanus. 1180 Pharmacy. Equal parts of Caustic Potassa and Quicklime, rubbed together, and kept in well-stopped bottles, form the Vienna Caustic (Potassa cunt Calce). It is milder than the preceding, and has been particularly recommended for cauterizing the neck of the uterus. It is also prepared in sticks. (See Calx, Part II, page 284.) Potassa Acetas. Acetate of Potassa. Preparation.—Take of Acetic Acid a pint; Carbonate of Potassa a sufficient quantity. Add the Carbonate of Potassa gradually to the Acetic Acid till it is saturated; then filter, and evaporate cautiously, by means of a sand-bath, until a dry salt remains. Keep this in closely-stopped bottles.— U. S. History. — It was formerly the method, in preparing this salt, to neu- tralize distilled vinegar with carbonate of potassa, and then evaporate; but by pursuing it, a salt of a reddish or brownish color would be obtained, arising from the organic matter contained in the vinegar, and which required some trouble and dexterity in manipulation to remove. By employing acetic acid or colorless pyroligneous acid, and a pure carbonate, a salt is obtained of sufficient purity and whiteness for medi- cal use. Care should be observed, that no excess of alkali exists, as in this case it will react on the acid during evaporation and give rise to discoloration; a slight excess of acid is not liable to such objections. The heat employed in drying the acetate of potassa should be the chlo- ride of calcium bath on the small scale, or steam under pressure on the laro-e scale; as that of a vapor-bath is too low for thorough desiccation and that of a sand-bath may become entirely too high. Acetate of potassa prepared by the above process is in the form of soft fibrous masses, and when pure is white, inodorous, soapy to the touch, neutral, and of a warm, saline, pungent taste. As met with in the shops, it has a foliated texture, somewhat resembling spermaceti in appearance, on account of which, it Avas formerly called Foliated Earth of Tartar. It is extremely deliquescent Avhen exposed to the air, becoming converted into an oily-like liquid, and should consequently be kept in well-stopped bottles. Heat fuses it, and if continued or increased, decomposes it, converting the acetic acid into acetone and carbonic acid, leaving the carbonate of potassa remaining. Acetate of Potassa is solu- ble in half its weight of temperate water, and twice its weight of alcohol. The salt exists in the juices of many plants, and is the chief source of the carbonate of potassa existing in wood-ashes. It is incompatible with the mineral acids, sulphates of soda, and magnesia, corrosive sublimate, nitrate of silver, and several other earthy and metallic salts. It is com- posed of one equivalent of acid 21, one of base 47.2, and two of Avater 18=116.2, (A-L.KO+2 Aq.) As noAv prepared, Acetate of Potassa is but little liable to adultera- tion ; but when impurities are present the principal ones are sulphate of Potassa. 1181 potassa, tartrate of potassa, chloride of potassium, and the salts of lead and copper. The salts of copper may be detected by ferrocyanuret of potassium which gives a brown precipitate; those of lead by sulphureted hydrogen which occasions a blackish precipitate. Chloride of potassium may be distinguished by adding nitrate of silver to a dilute solution; if it be added to a concentrated solution, soluble crystals of acetate of silver will be formed. Tartrate of potassa will remain undissolved, when the salt is placed in alcohol; and the sulphate of potassa may be ascertained by the chloride of barium. Properties and Uses.—Acetate of Potassa in doses of from a scruple to a drachm, acts as a diuretic, and has been used with good effect in dropsy, uric acid diathesis, and in other cases where diuresis is indi- cated. It has likewise been found beneficial in several cutaneous diseases, as eczema, lepra, psoriasis, etc. In these cases it acts energetically as a diuretic, and effects cures in from three weeks to two months. Half a drachm of the salt dissolved in Avater, may be given, and repeated three times a day. In doses of two or three drachms it acts as a mild cathar- tic. Two drachms of the carbonate of potassa saturated with distilled vinegar, will produce a copious discharge of urine, and, in dropsical cases, ten or twelve stools. This salt was formerly called Sal Diureticus. Off. Prep.—Tinctura Ferri Acetatis. Potassa Bicarbonas. Bicarbonate of Potassa. Preparation.—Take of Carbonate of Potassa four pounds; Distilled Water ten pints. Dissolve the Carbonate of Potassa in the Water and pass Carbonic Acid through the solution till it is fully saturated. Then filter, and evaporate the filtered liquor that crystals may form, taking care that the heat does not exceed 160°. Pour off the supernatant liquid, and dry the crystals upon bibulous paper. Carbonic Acid is obtained from marble by the addition of dilute sulphuric acid.— U S. History. — By this process, the carbonate of potassa containing one equivalent of acid and one of base, becomes combined with an additional equivalent of carbonic acid. The salt used should ahvays be pure, or else there will be siliceous impurities present, to separate which, is the reason for the filtration ordered in the above formula. Bicarbonate of Potassa may be made by several other processes, among which may be mentioned the forming a solution of carbonate of potassa in its own weight of water, adding about half its weight of ses- quicarbonate of ammonia, heating the solution to about 130°, and stir- ring occasionally, until small crystals begin to form. In this process, ammonia is evolved, and the ammoniacal carbonate is taken up by the potassa salt, and while slowly cooling, crystals of bicarbonate of potassa are formed. Christison recommends a quick, certain, and economical mode of preparing it. Sesquicarbonate of ammonia, in very fine powder, is to be thoroughly mixed with carbonate of potassa, by the aid of a very 1182 Pharmacy. little Avater, triturating briskly until a perfectly smooth, thick, uniform pulp is formed. Dry this pulp by a gentle heat, not exceeding 130° or 140°, and continue the drying until an ammoniacal odor ceases to be given off. By the drying, ammonia is evolved, and its carbonic acid combines with the carbonate of potassa, so that when the sesquicarbonate becomes wholly decomposed and all its ammonia volatilized, a pure bicarbonate of potassa is left behind, which may be reduced to a fine powder. A common mode of preparing Bicarbonate of Potassa, among manu- facturers, is to suspend a solution of the pure carbonate, within a cask, over a liquid undergoing the vinous fermentation, and allow it to remain there for six or seven weeks; the carbonic acid evolved is absorbed by the carbonate of potassa, and a bicarbonate is formed. Distillers and brewers often prepare it in this manner—and the Sal a'eratus of com- merce, which is between a carbonate and a bicarbonate in its composi- tion, is made in this Avay. Bicarbonate of Potassa crystallizes in colorless, transparent, right- rhombic prisms, usually truncated on the acute edges; their primitive form is the rectangular octaedre. It is inodorous, slightly alkaline to the taste, permanent in the air, soluble in four parts of cold water, but insoluble in boiling water without decomposition, carbonic acid being liberated and a sesquicarbonate of potassa formed; it is also insoluble in alcohol. At a red-heat it loses about 30.7 per cent., or all its water of crystallization, and half its carbonic acid, and is converted into a very pure carbonate. It has no power of dissolving or disorganizing the animal textures. It consists of two equivalents of acid 44, one of base 47.2, and one of water 9 = 100.2, (2 C02+KO+Aq.). Bicarbonate of Potassa is subject to adulterations of the sulphate or muriate of potassa, from having employed an impure carbonate in its preparation ; and of carbonate of potassa from some defect in the process of making it. The sulphate and muriate of potassa may be detected by chloride of barium or nitrate of silver causing a white precipitate in its solution supersaturated by nitric acid. Carbonate of potassa may be known by adding a solution of corrosive sublimate, which will cause a brick-red precipitate, if even the hundredth part of the carbonate be present; a solution of the pure bicarbonate in forty parts of water has no effect, or at most, produces merely a Avhite haze. The carbonate may also be detected by adding starch sugar to a heated solution of the bicarbonate under examination ; if the impurity be present, the solution becomes changed to yellow or brown. Properties and Uses.—Bicarbonate of Potassa is antacid, antilithic, and diuretic, is less irritating and unpleasant than the carbonate, and maybe used in larger doses. It is preferred as a general rule to the Carbonate, for which it may in nearly all cases be used as a substitute. Dose, ten Potassa. 1183 to tAventy grains as an antacid and antilithic ; one to two drachms, as a diuretic. Off. Prep.—Extractum Rhei et Potassae Fluidum; Pulvis Rhei Com- positus ; Syrupus Rhei et Potassae. Potassa Bichromas. Bichromate of Potassa. Preparation.—Take of the neutral or yellow Chromate of Potassa any quantity; Water a sufficient quantity. Dissolve the Chromate in the Water, filter, warm the filtered solution, and while warm acidulate the solution Avith sulphuric acid; then set the mixture aside for two or three days, when beautiful orange-red crystals of bichromate of potassa will be formed. History.—The addition of sulphuric acid to the filtered solution, as above explained, separates one equivalent of potassa from two of the neutral chromate, thus converting the salt into a bichromate. The yelloAv chromate, from which is prepared the bichromate, may be obtained by igniting four parts of powdered chrome-iron ore, with one part of nitre, and lixiviating the resulting mass with water. The solution when evaporated, yields the chromate in crystals. By this process, oxygen is furnished by the nitric acid of the nitre, and the sesquioxide of chro- mium is converted into chromic acid, which then combines with the potassa of the same salt; the iron likewise becomes sesquioxidized and insoluble. Bichromate of Potassa is in anhydrous, prismatic crystals, of an orange- red color, having a cooling, bitter taste, insoluble in alcohol, and soluble in ten parts of cold and much less boiling water. It fuses at a red-heat without decomposition, forming a red liquid, which on cooling congeals into a crystalline mass and then falls to powder. It is manufactured largely for the use of calico printers, and those engaged in making it are subject to painful ulcerations of the hands. Paper impregnated with its solution, and dried, forms excellent tinder. It is composed of two equivalents of chromic acid 104.06, and one of potassa 47.2=151.26; its formula is KO, 2 Cr, 0. Properties and, Uses.—Bichromate of Potassa is an irritant and caus- tic, its only therapeutical use is as an external application; when brought in contact with the skin, its solutions cause very painful sores, which are difficult to heal. A saturated solution of it has been recommended as an application to warts, excrescences, hemorrhoidal tumors, scirrhous tumors, tuberculous elevations, and to promote the healing of ulcers. About from half a drachm to a drachm of the salt may be added to a fluidounce of water. When used as a caustic, it must be applied in the form of powder. Its solution possesses very powerful antiseptic proper- ties, and will be found advantageous in cases of gangrene, dry mortifi- cation, etc. This salt is also used as a source of chromic acid, of oxygen, 1184 Pharmacy. and in the forming artificial valerianic acid for the purpose of preparing valerianate of soda. Potassa Bisulphas. Bisulphate of Potassa. Preparation.—Take of the residuum, in the preparation of pure Nitric Acid two pounds; commercial Sulphuric Acid seven fiuidounces and one fluidrachm, (Imperial Measure) ; Boiling Water six pints, (Imp. Meas.) Dissolve the Salt in the Water, add the Sulphuric Acid, concentrate the solution, and set it aside to cool and form crystals. History.—The salt which remains after the distillation of nitric acid is a bisulphate of potassa ; but Mr. Phillips states that when it is dissolved in Avater, and the solution allowed to crystallize, some sulphate and much sesquisulphate are obtained instead of bisulphate, owing to the water retaining a part of the excess of acid in solution. By the addition of sulphuric acid this result is prevented, and the bisulphate forms in crys- tals. The above is the formula of the Edinburgh College; the Dublin College have given another, which also yields a pure bisulphate—it is as follows: Take of Sulphate of Potassa, in powder, three ounces, (Avoir- dupois) ; Pure Sulphuric Acid one fluidounce, (Imp. Meas.) Place the Acid and Salt in a small porcelain capsule, and to this apply a heat capable of liquefying its contents, and which should be continued until acid vapors cease to be given off. The Bisulphate, which concretes as it cools, should be reduced to a fine powder, and preserved in a well stopped bottle. Bisulphate of Potassa crystallizes in small oblique, flattened, right- rhombic prisms ; or when obtained by extreme concentration and cooling, it has the appearance of a firm, fibrous mass. It is a white salt, with a bitter and strongty acid taste, the crystals being permanent in the air, Avhile the fibrous mass effloresces. It is soluble in twice its weight of cold, and in less than its weight of boiling water. It is insoluble in alcohol, Avhich precipitates the neutral sulphate from the aqueous solu- tion. Exposed to a moderate heat it fuses and runs like oil; at a red heat, it is deprived of water and its excess of acid, and is converted into the neutral sulphate. It is incompatible with many of the metals, most oxides, the alkalies, earths, and their carbonates. It may be distin- guished from other salts by its strong acid taste, and by its brisk effer- vescence with an alkaline carbonate, the solution after effervescence, presenting the characters of the neutral sulphate. This salt was formerly known by the name of sal enixum. It is composed of two equivalents of acid 80.2, one of base 47.15, and two of water 18=145.35; its formula is 2 S03 + KO, 2 Aq. Properties and Uses. — Bisulphate of Potassa is laxative and tonic, and is beneficial in constipation accompanied with a deficient appetite, especially during convalescence from acute disease; and is said to form a grateful adjunct to rhubarb. A drachm, each, of the bisulphate, and Potassa. 1185 of carbonate of soda, dissolved separately, each in two fluidounces of water, and then mixed, forms a good aperient effervescent draught. The dose of the bisulphate is one or two drachms. Potassa Carbonas. Carbonate of Potassa. Preparation.—Take of Impure Carbonate of Potassa, (pearlash) in powder, three pounds; Water two pints and a half. Dissolve the im- pure carbonate of potassa in the water, and filter the solution, then pour it into a clean iron vessel, and evaporate the water over a gentle fire, until the solution thickens ; lastly, remove it from the fire and stir it con- stantly with an iron spatula until the salt granulates.— U.' S. History.—By the above process the impure Carbonate of Potassa is purified. The solution in cold water is allowed to stand for a few days, frequently stirring it, and is then filtered, which removes its insoluble impurities, as well as many foreign salts which have not as great an affinity for water as the carbonate, and therefore are not dissolved. The filtered solution is then placed in iron vessels, because glass is acted on by the potassa, and evaporated. In the latter part of the process, when the solution is brought nearly to dryness, it is better to keep it on the fire at a reduced heat, removing it the moment the solution thickens. Carbonate of Potassa is in small roundish grains, white, opake, of a nauseous alkaline and caustic taste, soapy to the touch when moist, and extremely deliquescent, forming, when exposed to the air, an oily liquid, termed by the early chemists oleum tartari per deliquum. It exerts an alkaline reaction on vegetable colors, is very soluble in water, and insol- uble in alcohol. On account of its deliquescence it should always be kept in well stopped bottles. A red heat drives off 16 per cent, of its water without any loss of its carbonic acid ; dilute sulphuric acid decom- poses it, evolving 26.3 per cent, of carbonic acid. It is incompatible with acids and acidulous salts, muriate and acetate of ammonia, limewater, chloride of calcium, sulphate of magnesia, alum, tartar emetic, nitrate of silver, ammoniated copper, and ammoniated iron, sulphate of iron, and tincture of muriate of iron, calomel and corrosive sublimate, acetate and subacetate of lead, and sulphate of zinc. As it is not decomposed by the tartrate of iron and potassa, it may be employed with it in prescrip- tions. It is composed of one equivalent of acid 22, and one of base 47.2=69.2 (CO^+KO.) The most common impurities met with, are excess of moisture, earthy matter, sulphate of potassa,. chloride of potassium, and silica. Its solu- tion supersaturated with nitric acid, will show the presence of minute portions of a sulphate by giving a faint cloudiness with chloride of barium ; and of a chloride by yielding a slight precipitate Avith nitrate of silver. Should earthy matter be present, carbonate of soda will precipi- tate the nitric solution. The pure commercial carbonate may be known Dy five parts of it saturating 5.44 parts of tartaric acid, which has been 75 1186 Pharmacy. gently dried so as not to drive off any of its water of crystallization. As nearly all samples of carbonate of potassa contain more or less moisture, due allowance should be made for this in all chemical or pharmaceutical operations. Properties and Uses.—All the carbonates of potassa are sufficiently corrosive to be energetic poisons. They occasion destruction of the mucous membranes of the fauces, oesophagus, stomach, and sometimes of the intestines—indicated at first by violent burning pain, prostration and vomiting, which is sometimes bloody, and if death does not ensue in consequence, in a few days, excessive emaciation follows, and con- stant irritation of the stomach and bowels. The proper antidotes to them are vinegar, lemon-juice, or fixed-oil. Medicinally, Carbonate of Potassa is antacid, antilithic and diuretic. Useful in urinary affections, where the morbid secretion consists of lithic acid, and the lithates, for which about thirty-five grains should be given in the course of the day, in divided doses. Some prefer the potassa carbonates to the soda, for antilithic purposes, on the supposition that they are more energetic solvents. It is sometimes used in solution, as an injection into the bladder, for calculus. It has also been employed in dyspepsia, as an antacid; in dropsy, as a diuretic; and in some cases of jaundice; and combined with cochineal, it has considerable repu- tation in the treatment of pertussis. Dissolve carbonate of potassa, twenty grains, in a gill of water, add to it ten grains of powdered cochineal, sweeten with loaf sugar, and give an infant a teaspoonful four times a day ; to a child two or three years old, two teaspoonfuls; four years and upward, a tablespoonful or more. To this preparation, five to fifteen drops of tincture of belladonna is sometimes added. Externally, it is used in the form of bath, lotion, or ointment, as an effectual remedy in obstinate cutaneous eruptions. From eight to six- teen ounces may be used for a single bath; from two to three drachms in a pint of water, for a lotion; or from ten to sixty grains with an ounce of lard, as an ointment. Dose of the powder in solution, five to thirty grains. Off.

Potassa Carbonas Purus. Pure Carbonate of Potassa. Salt of Tartar. Preparation.—Take of Bicarbonate of Potassa a pound. Put the Bi- carbonate, previously powdered, into a capacious iron crucible, heat gradually until the water of crystallization is driven off, then raise the heat to redness, and maintain that temperature for half an hour. Having taken the crucible from the fire, and allowed it to cool, remove its contents, dissolve them in Distilled Water, filter the Solution, and Potassa. 1187 complete the process by evaporating and granulating as directed for Carbonate of Potassa.— U. S. History.—In the above process, by ignition of the bicarbonate of potassa, it is deprived of one equivalent of carbonic acid together with its water of crystallization, and the carbonate remains. The bicarbonate being usually a very pure salt, the carbonate procured from it is like- wise as pure. Pure carbonate of potassa differs from the carbonate in holding no impurities; its actions are the same. It was formerly called Salt of Tartar, but, the greater part of this salt at present found in the shops, is the ordinary carbonate as purified from pearlash. It may also be made as follows; take of Bitartrate of Potassa (cream of tartar), two pounds; Nitrate of Potassa, a pound. Rub them separately into powder, then mix, and throw them into a brass vessel, heated nearly to redness, that they may undergo combustion. From the residue pre- pare the purest carbonate of potassa, in the manner directed for the carbonate. Properties and Uses.—Precisely the same as those of the Carbonate of Potassa. The Liquor Potassae Carbonatis, Solution of Carbonate of Potassa, is made by dissolving one pound of Carbonate of Potassa in twelve fluid ounces of Distilled Water, and then filtering the solution. The dose is from ten to sixty drops, sufficiently diluted with water or other bland liquid. Potassa Chloras. Chlorate of Potassa. Preparation. —Dissolve one equivalent of Caustic Potassa in sufficient Water to form a Solution, containing 10^ per cent, of the alkali (sp. gr. 1.110), then mix the solution with Hydrate of Lime (Quicklime), five and a half equivalents; heat the mixture gradually to 122°, and subject it to a rapid current of Chlorine to saturation, the reaction caused by which raises the temperature to about 194°. The product is then evapo- rated nearly to dryness, the residue dissolved in Boiling Water, and the Solution filtered and set aside to crystallize. History.—This is the process of Prof. F. C. Calvert of Manchester, by which 260 parts of chlorate are obtained from 100 of anhydrous potassa, while by the old methods but 43 parts were procured. In the above process the combination of chlorine with the calcium, instead of the potassium, is determined by the temperature and the strength of the potassa solution; while the chlorine is converted into chloric acid by the oxygen from the lime. A higher or lower density of the solution of potassa gives less favorable results. Chlorate of Potassa crystallizes in four or six-sided rhomboidal platea, white, of a pearly luster, and permanent in the air. It has a cooling, saline taste like that of nitre. It is soluble in two and a half parts of 1188 Pharmacy. boiling water, and in sixteen parts of water at 60°. Heat fuses it, and if carried to a little beyond its point of fusion, nearly 39 per cent, of oxygen is disengaged, leaving a residuum of chloride of potassium. It is due to this escape of oxygen that the combustion of burning fuel is enlivened when the salt is thrown upon it. Mixed with a little sulphuric acid it becomes first yellow, and then red, and chlorous acid gas (quad- roxide of chlorine) is evolved, which has a yellow color, and is explosive when heated. When triturated with a small piece of phosphorus or sulphur, a violent explosion ensues; mixed first with muriatic acid, and then with water it becomes possessed of bleaching power. It consists of one equivalent of chloric acid 75.42, and one of potassa 47.2=122.62, (ClOs+KO). From faulty preparation, its most common impurity is chloride of potassium. This may be detected by the addition of nitrate of silver to its solution, which will occasion a white precipitate of chloride of silver, if the impurity be present. Properties and Uses.—Chlorate of potassa is considered a refrigerant and diuretic; and has been used in cholera, and in malignant fevers for promoting the arterialization of the blood; it is also said to moisten and clean the tongue. According to Dr. O'Shaughnessy and other physi- cians, it passes unchanged into the urine, and imparts a bright scarlet color to the venous blood. It has been used with considerable benefit in scurvy, syphilis, and liver complaint; and is strongly recommended in cancrum oris, given in solution, in divided doses, to the amount of from ten to sixty grains in twenty-four hours, according to the age of the child. It lessens the fetor and salivation attendant on the disease, and promotes granulation. Internally, and used as a mouth wash, it has been recommended in erysipelatous inflammation of the mouth and fauces, occurring in black tongue. The dose is from ten to thirty grains; and the mouth wash made by dissolving a drachm of the salt in four fluidounces of water. Potassa Sesquicarbonas. Sesqui-carbonate of Potassa. Vegetable Caustic. Preparation.—Take of Bicarbonate of Potassa one pound; Water a sufficient quantity. Dissolve the Bicarbonate in the Water, strain and then evaporate by means of heat raised to a very few degrees above the boiling point; when sufficiently concentrated set aside to cool. Dry the resulting sesquicarbonate by a gentle heat. History.—This is the method at present pursued in the preparation of the Vegetable Caustic. The bicarbonate of potassa becomes partially decomposed during the evaporating process, but whether it is converted into a true sesquicarbonate of potassa (2KO, 3CO2), or is deprived of half its carbonic acid, remains yet to be determined. Sesquicarbonate of Potassa, as prepared by the above process, is sold Potassa. 1189 in the form of a white powder, having a pungent, but not very powerful, alkaline odor, a sharp, strongly alkaline taste, is permanent in dry air, very soluble in water, but insoluble in alcohol. It is incompatible with the same substances as the Carbonate of Potassa. The above preparation differs very materially from the original vegetable caustic, which was prepared by making a strong ley of hickory or oak- wood ashes, and evaporating it, in an iron kettle, to dryness. This formed an impure caustic potassa, of a dingy-gray or greenish color, very caustic, but less so than the hydrate of potassa, very deliquescent, and soluble in water. It is more severe in its action than the sesquicar- bonate, and has occasionally to be employed in cases where that exerts but little or no beneficial influence. As it rapidly attracts moisture from the atmosphere, it must, as soon as prepared, be placed in green glass bottles with good corks or stoppers. Properties and Uses.—Each of these preparations are escharotic, but do not, like the hydrate of potassa, destroy or decompose the healthy tissues; their action appears to be altogether exerted upon abnormal growths and conditions of parts. They are employed as local applica- tions to fistulas, cancers, fungous growths, indolent ulcers, unhealthy conditions of mucous tissues, as in ophthalmic affections, disease of the Schneiderian membrane, of the mouth and throat, urethra, vaginal walls, and cervix-uteri. In solution, it has been injected into the uterus in dysmenorrhea, uterine leucorrhea, etc., without any unpleasant symptoms arising. In these latter cases the milder sesquicarbonate must be used, commencing with a weak solution, and gradually increas- ing in strength, until the maximum degree that can be used, is obtained. Upon healthy tissues these agents exert but very feeble action; and in unhealthy conditions they bring about a normal action without exciting an undue degree of inflammation. They are peculiarly Eclectic agents of great value. Potassa Sulphas. Sulphate of Potassa. Preparation.—Take of the Salt which remains after the distillation of Nitric Acid two pounds; Boiling Water two gallons. Ignite the Salt in a crucible until the excess of the Sulphuric Acid is entirely expelled; then boil it in the two gallons of Water until a pellicle forms, and, the liquor being strained, set it aside that crystals may form. Pour off the liquor from the crystals and dry them. History.—When a mixture of Nitre and Sulphate of Iron is calcined for the. purpose of obtaining nitric acid, the residue consists of sulphate of potassa and sesquioxide of iron ; the former may be separated from the latter by solution in water, concentration, and crystallization. The sulphate may also be procured by other processes, as by the action of sulphuric acid on nitre in the distillation of nitric acid ; by the decom- position which ensues when carbonate of potassa and sulphate of 1190 Pharmacy. magnesia react upon each other, during the preparation of carbonate of magnesia, etc. The salt which remains after the distillation of nitric acid, is a super- sulphate of potassa, and by the application of heat to remove the excess of acid, it is brought into the neutral state. The excess of acid may also be removed by the addition of white marble, or slaked lime, either of which become converted into insoluble sulphate of lime. This ac- complished, the liquor or solution of the sulphate of potassa is strained, evaporated, strained again, and allowed to cool, when the crystals form. This salt also occurs in volcanic regions and in the juices of plants; but the medicinal article is always an artificial preparation. It has at dif- ferent times been known under the names of Sulphate of Kali, Vitriolated Tartar, Sal-Polychrest, Sad de Duobus, etc. Sulphate of potassa occurs in small, aggregated, transparent, white, very hard crystals, whose primary form is the right rhombic prism or rhom- bic octaedre, but which generally are short six-sided prisms terminated by six-sided pyramids. They have a sharp, saline, bitterish, and nau- seous taste, are permanent in the air, soluble slowly in about nine and a half parts of cold water, soluble in nearly four times their weight of boiling water, and insoluble in alcohol. Heat causes a slight decrepi- tation ; and a strong red heat fuses them, but without change ; heated with carbonaceous matter the sulphate is deoxidized, and sulphuret of potassium formed. A solution of sulphate of potassa slightly acidulated with nitric acid, yields a white precipitate with chloride of barium, and a yellow one with chloride of platinum. It is incompatible with tartaric acid which unites with it to form bitartrate of potassa, and with the soluble salts of lime, silver, strontia, baryta, and lead, with which it forms insoluble or sparingly soluble sulphates. It is not subject to adulteration. It is composed of one equivalent of acid 40, and one of potassa 47.2=87.2, (S03+KO). Properties and Uses.—Sulphate of potassa is a mild cathartic, and causes but little pain, heat, or irritation during its operation. In doses of one or two ounces, it acts as a powerful irritant, and has given rise to fatal accidents. It has been used as an aperient after delivery, for the purpose of removing visceral obstructions of children attended with defective digestion and nutrition, and tumid abdomen, and in jaundice and dyspeptic affections. The dose as an aperient is from a scruple to half a drachm ; in larger doses, say four or five drachms, it acts slowly as a purge. It should always be sufficiently diluted with water, when administering it. Potassa Sulphas cum Sulphure. Sulphate of Potassa with Sulphur. Preparation.—Take of Nitrate of Potassa, in powder, and of Sublimed Sulphur, equal weights. Mix them well together, and throw the mixture, by small portions at a time, into a red hot crucible. When the Potassa. 1191 deflagration is over, allow the Salt to cool, and place it in a glass vessel well stopped. History.—As the above named portions of the mixture are thrown into the red-hot crucible, they melt, and on the surface of the fused mass floats the sulphur, having the appearance of a brown oil ; it burns with a blue flame, throwing out in copious quantity sulphuric acid gas, and becoming oxidated at the expense of the nitric acid of the nitre, which is totally decomposed, and enabled to furnish a sufficient quantity of oxygen for the above purpose. The product of this deflagration is a grayish-white friable substance, the nature of which has not been ascertained. It has an acid and sulphurous taste, and an acid reaction with test- paper ; it is much more soluble in water than sulphate of potassa, giving off a sulphurous smell during its solution, which solution is yellowish. Sulphureted hydrogen is not obtained on the addition of an acid to it, nor is sulphuret of lead thrown down by the salts of lead. Its powder is pale yellowish-white; and it dissolves in eight times its weight of cold water. A white precipitate, insoluble in nitric acid, is occasioned by the salts of barium, so that sulphate of potassa is present, and with which, its other properties coincide. Even when prepared with equal care, it exhibits, in different specimens, some variety in its properties. Properties and Uses.—This preparation is considered a mild cathartic, resembling very much in its action, that of the sulphate of potassa. It was formerly much in vogue as a purgative in dyspepsia, chronic cuta- neous eruptions, etc. The dose is from half a drachm to a drachm, and generally given with some other gentle laxative, as bitartrate of potassa. Potassa Tartras. Tartrate of Potassa. Soluble Tartar. Preparation. —Take of Carbonate of Potassa sixteen ounces; Bitartrate of Potassa, (Cream of Tartar,) in powder, three pounds or a sufficient quantity; Boiling Water a gallon. Dissolve the Carbonate of Potassa in the Water, then gradually add the Bitartrate of Potassa, until efferves- cence ceases, or until the solution is perfectly saturated, then boil. Filter the solution through paper; then evaporate it till a pellicle forms, and set it aside to crystallize. Pour off the Water, dry the Crystals upon bibulous paper, and keep them in closely stopped bottles.— U S. History.—Tartrate of Potassa, also known by the names of Soluble Tartar, Sal Vegetabile, and Tartarized Kali, was known as early as the seventeenth century. In the above process for obtaining it, the potassa of the carbonate saturates the excess of acid of the bitartrate, while at the same time the carbonic acid is given off with effervescence, and at the termination a neutral tartrate of potassa is formed. As the carbon- ate of potassa is more readily soluble than the bitartrate, it should be dissolved first, and the latter added, (promoting the action by constant 1192 Pharmacy. stirring,) until the saturation is completed, and which may be known by the cessation of effervescence. As the solution should be neutral, or very slightly alkaline, should too much bitartrate have been added, the solution may be changed to its proper neutrality by a little more of the carbonate. After saturation, the tartrate of lime, which is deposited in white flocks, must be separated by filtration, and the evaporated solu- tion then placed in warm earthenware Aressels, (not iron, as it is apt to discolor the salt,) to procure a gradual cooling, and after several days, the crystals commence forming. If the solution be somewhat alkaline, crystallization ensues more favorably. Tartrate of potassa, when properly prepared, is in the form of white, transparent crystals, which are right rhombic prisms, or irregular six- sided prisms, terminated by two converging planes. It has a mildly saline, bitterish taste, is neutral to test paper, becomes moist in damp air without deliquescence, is soluble in about twice its weight of cold water, and in much less of boiling water, and is almost insoluble in alcohol. At a heat of-250°, its water of crystallization is driven off, but without fusion, and it becomes anhydrous ; at a higher heat it is decomposed, fusing, SAvelling up, and becoming finally converted into charcoal and carbonate of potassa. The crystals alone should be employed for me- dical use, and not the white granular powder of the shops, obtained by constantly stirring the solution while evaporating to dryness. It is sel- dom adulterated. It is incompatible with all the strong acids, and with many acidulous salts. Its solution is precipitated by the salts of baryta, silver and lead, forming white tartrates of the metallic oxides, which are soluble in dilute nitric acid. It is composed of one equivalent of acid 66, and one of potassa 47.2=113.2—the crystals having no water of crystallization, KO, Gt H2 Oo. Properties and Uses.—Tartrate of potassa is a mild cooling purgative, operating without much pain, and producing watery stools. Used in febrile diseases, and occasionally combined with senna to obviate its griping effects. Dose, from a drachm to an ounce. Potassii Bromidum. Bromide of Potassium. Preparation.—Take of Bromine two ounces; Iron Filings an ounce; Carbonate of Potassa two ounces and a drachm, or a sufficient quantity; Distilled Water four pints. Add first the Iron Filings, and afterward the Bromine, to a pint and a half of the Distilled Water, stirring the mixture frequently with a spatula for half an hour. Apply a gentle heat, and, when the liquor assumes a greenish color, add gradually the Carbonate of Potassa, previously dissolved in a pint and a half of the Distilled Water, until it ceases to produce a precipitate. Continue the heat for half an hour, and then filter. Wash the precipitate with the remaining pint of Distilled Water, boiling hot, and filter. Mix the fil- tered liquors, and evaporate so that crystals may form. Lastly, pour off the liquid, and dry the crystals on bibulous paper.— U. S. Potassa. 1193 History.—In this process, the addition of the iron and bromine to the water, forms a solution of bromide of protoxide of iron, which is decom- posed by the subsequent addition of the carbonate of potassa, the car- bonate of protoxide of iron being precipitated, while the bromide of potassium is held in solution. The carbonate of iron is separated from the solution by filtration, and by the evaporation bromide of potassium is obtained in crystals. Bromide of Potassium crystallizes in cubes or rectangular four-sided tables, which are permanent in the air, of a pearly luster, and anhy- drous; and possessing a pungent, saline taste, somewhat like that of common salt. It is very soluble in water, sparingly so in alcohol, decrep- itates when heated, and at a red-heat fuses without becoming decom- posed. Its aqueous solution has no action on litmus or turmeric, is not precipitated by chloride of barium, but is decomposed by sulphuric, nitric, and muriatic acids, which set free bromine, and the liquid becomes brown. Mixed with starch and then acted upon by sulphuric acid, the bromine is disengaged, and the liquid becomes yellow. Nitrate of silver 14.28 grains are required to completely precipitate ten grains of the bro- mide of potassium, the precipitate being yelloAvish. A few drops of a weak solution of chlorine added to its solution, will indicate the presence of iodine, by imparting a faintly blue or violet color to a piece of white paper moistened with the liquid. It is composed of one equivalent of bromine 78.4, and one of potassium 39.2=117.0, (K Br.) Properties and Uses.—Bromide of Potassium is considered an altera- tive and resolvent. It has been recommended in enlarged spleen, scrofula, secondary and tertiary syphilis. In the latter diseases, its effects are slow and unsatisfactory compared with those of Iodide of Potassium; in large doses it is said to produce nausea, gastric derange- ments, drowsiness, torpor, anaesthesia of the fauces, and debility of the genital organs. Externally, it has been used in the form of ointment, in conjunction with its internal use, or that of iodine, and has proved efficacious in bronchocele, scrofula, and enlarged spleen. The dose of it is from three to ten grains, three times a day, in pill or solution. The ointment is made by mixing from two scruples to two drachms of the bromide with an ounce of lard; of which from one-fourth to one-half may be rubbed over the affected part, once in twenty-four hours. Potassii Cyanuretum. Cyanuret of Potassium. Preparation. — Take of Ferrocyanuret of Potassium, dried, eight ounces; Carbonate of Potassa, dried, three ounces. Mix the salts inti- mately, and throw the mixture into a deep iron crucible previously heated to redness; maintain the temperature till effervescence ceases, and the fused mass concretes, of a pure white color, upon a warm glass rod dipped into it; then pour out the liquid carefully into a shallow dish to solidify, stopping before the Salt becomes contaminated with the precipitated 1194 Pharmacy. iron. Break up the mass while yet warm, and preserve it in well stopped bottles.— U S. History.—In this process two equivalents of carbonate of potassa, and two of ferrocyanuret of potassium react upon each other ; carbonic acid is eArolved, iron is set free, and a compound is formed consisting of five equivalents of cyanuret of potassium, and one of cyanate of potassa. The iron settles at the bottom of the fused liquid, which must be care- fully poured off to avoid any contamination with the iron. The cyanate of potassa is not present in sufficient quantity to injure the medicinal action of the salt; and it may be detected by saturating the product with an acid, which will evolve carbonic acid with effervescence, and give rise to an ammoniacal salt. ( The process for preparing cyanuret of potassium, according to the French Codex, is to half fill a coated stoneware or iron retort with the ferrocyanuret, attach a tube to it for the purpose of collecting the gas- eous products, and apply heat, until the gases cease to be disengaged; then raise the heat to a very high temperature which must be maintained for half an hour. After this calcination, a black substance will be found in the retort, covered with a fused layer of pure cyanuret of potassium, resembling white enamel, which should be at once removed and placed into a well stopped bottle. The remaining mass is an impure black cyanuret of potassium. Cyanuret of potassium, as prepared by the above formula, is amor- phous, white, and opake, deliquescent in moist air, soluble in water, but sparingly so in alcohol. It has a sharp, alkaline, bitter-almond taste, and an alkaline reaction. It is always white when pure, but any con- tamination with iron renders it yellow. Exposed to the air it loses its strength gradually either in mass or solution. As found in commerce it varies considerably in regard to purity ; the usual impurities are water, carbonate, cyanate, and formiate of potassa. Nitrate of silver added to its solution precipitates cyanuret of silver, which is completely soluble in ammonia. Cyanuret of potassium is composed of one equivalent of cyanogen 26, and one of potassium 39.2=65.2, (K Cy). Properties and Uses.—Cyanuret of Potassium is poisonous, acting precisely like hydrocyanic acid. Medicinally, it has been proposed as a substitute for that acid, on account of its greater uniformity of strength, and its less liability to decomposition. The dose is one-eighth of a grain, dissolved in half a fluidounce of distilled water, to which may be added some aromatic syrup, or if it is desired to set free the hydrocyanic acid, half a fluidrachm of. lemon-syrup may be added. Great care must be employed in using this preparation. Externally, four grains of the salt to a fluidounce of distilled water, has been efficaciously used in neu- ralgic and other local pains, applied by means of lint or linen. The Potassa. 1195 solution dropped into the eye every other day, will, it is said, remove the olive colored stains of the conjunctiva, produced by the nitrate of silver. Potassii Iodidum. Iodide of Potassium. Preparation.—Take of Potassa six ounces; Iodine, in powder, sixteen ounces ; Charcoal, in fine powder, two ounces ; Boiling Water three pints. Dissolve the Potassa in the Water, add the Iodine gradually, stirring after each addition until the solution becomes colorless, and continue the additions until the liquid remains slightly colored from excess of Iodine. Evaporate the solution to dryness, stirring in the Charcoal toward the close, so that it may be intimately mixed with the dried Salt. Rub this to powder, and heat it to dull redness in an iron crucible, maintaining that temperature for fifteen minutes; then, after it has cooled, dissolve out the saline matter with pure Water, filter the solution, evaporate, and set aside to crystallize. An additional quantity of Crystals may be obtained from the residual liquid by evaporating and crystallizing as before.— U. S. History.—In this process, a slight excess of iodine is added to an aqueous solution of potassa, which results in the formation of two salts, Iodate of Potassa and Iodide of Potassium. The reaction of six equiv- alents of iodine with six of potassa, gives rise to the formation of five equivalents of iodide of potassium, and one of iodate of potassa. These salts are obtained together by evaporating the solution to dryness ; and to convert the iodate into iodide of potassium, the dried mass is exposed to a dull-red heat. The addition of charcoal toward the termination of the evaporation facilitates the deoxidation of the iodate, by exposure to a dull-red heat. The iodide of potassium is then dissolved from the mass, the solution filtered, evaporated, and set aside to crystallize. Iodide of Potassium, when pure, is in crystals or fragments of crystals, which are cubes or four-sided prisms, with a slight tendency to the rhom- bic form. They are colorless, and opake, with a faint odor of iodine, and a sharp, saline taste. In dry air they are permanent, but slightly deliquescent in a moist one. They have but little influence on litmus or turmeric. They dissolve in about two-thirds their weight of cold water, and in from six to eight parts of alcohol. Sulphuric acid decom- poses a solution of iodide of potassium, producing hydriodic acid, Avhich rapidly decomposes, setting free iodine; if starch be added, the liquid is changed to a blue color, after standing a short time ; but if any iodate be present, the blue color appears at once, in consequence of the imme- diate liberation of iodine. Tartaric acid added freely to a concentrated solution of iodine of potassium, occasions a white crystalline precipitate, and if starch be added to the supernatant liquid, it becomes first purple and then blue. Its solution is colored brownish-red by the addition of chloride of platinum, without occasioning a precipitate; it is but little 1196 Pharmacy. affected by chloride of barium ; and not at all by sulphate of iron, unless carbonate of potassa be present, when a whitish or greenish-Avhite pre- cipitate occurs, which effervesces on the addition of a diluted acid. A low red-heat fuses it, giving a crystalline pearly mass on cooling ; a full red-heat volatilizes it without decomposition. The solution of iodide of potassium possesses the property of dissolving a large quantity of iodine, forming a liquid of a deep-brown color, containing the iodureted iodide. Iodide of potassium consists of one equivalent of iodine 126.3 and one of potassium 39.2=165.5, (KI). It is exceedingly subject to adulteration, both from faulty manufacture, and fraudulent admixture. The most usual impurities are the iodate of potassa, carbonate of potassa, chlorides of sodium and potassium, and water. Iodate of potassa is generally present only as an accidental im- purity ; it may be detected by its insolubility in alcohol; also by the rich blue color produced at once by the addition of tartaric acid and starch solution. When pure, neither the iodide of potassium, nor the iodate of potassa are thus affected, but only when they become mixed. Carbonate of potassa may be present in the proportion of from one to five per cent., and even ten, without altering the crystalline appearance of the iodide ; but it increases its tendency to deliquesce. When the proportion is greater than this the iodide becomes granular and highly deliquescent. This impurity may be detected by the insolubility of the carbonate in alcohol; by the addition of limewater, which precipitates a milky carbonate of lime; and by its destroying the color of tincture of iodine when it is added to the solution. Chloride of sodium or potas- sium may be detected by the addition of nitrate of silver, which, if the salt be pure, will precipitate iodide of silver, which is hardly soluble in ammonia; but if the precipitate be soluble in ammonia it is a chloride of silver, and the salt is rendered impure by the presence of a chloride. If the ammonia be saturated with nitric acid, it will give up the chloride of silver as a white precipitate ; but if no chloride be present, the am- monia, as before said, takes up a very minute portion of iodide of silver, and the subsequent addition of nitric acid, will hardly disturb the trans- parency of the solution. The presence of water may be detected by heating the iodide in a glass tube, upon which the water will condense in the upper part of the tube. Bromide of potassium is also an adulte- ration which may be detected by bichloride of mercury, with which it causes no precipitate. Or, it may be detected by adding to an aqueous solution of the iodide, successively and in excess, a solution of sulphate of copper, and aqueous sulphurous acid ; filter the liquor, and treat it with ether and chlorine Avater. Shake the whole together and allow it to rest; if the ether, which rises to the surface, be tinged of a reddish- yellow color, bromine is present. Iodide of Potassium is often incor- rectly called by the name of Hydriodate of Potash. Potassa. 1197 Properties and Uses.—In large doses Iodide of Potassium is an irritant. In small doses it is diuretic and alterative ; it has been detected in the urine, in six minutes after being swallowed. This may be accomplished by adding a portion of starch to the cold urine, and then a feAv drops of nitric acid ; if the iodide be present, this will produce a blue color. In some constitutions Iodide of Potassium produces peculiar symptoms, such as dryness and irritation of the throat, irritation of the mucous mem- brane of the air passages, various cutaneous eruptions, excessive diure- sis, cerebral excitement resembling that caused by alcoholic liquors, vascular injection of the conjunctiva and tumefaction of the eyelids, and discharges from the vagina and urethra, simulating blennorrhea. Upon ceasing the use of the medicine, these various symptoms gradually disappear. Iodism is occasionally caused by it, or some of the symp- toms characterizing that influence. It appears to be more especially useful in goitre, strumous enlargement of the glands, strumous sores and eruptions, strumous ophthalmia, syphilitic affections, mammary tumors, enlargement of the liver, amenorrhea, leucorrhea, mercurio-syphilitic sore-throat, mercurial cachexy, and indeed all tubercular affections of serous tissues. It is extensively employed in the above forms of disease, by Eclectics, in combination with the Compound Syrup of Stillingia, in the proportion of four drachms of the Salt to a pint of the Syrup. When taken for a length of time, and especially if used in rather large doses, it will excite ptyalism, and frequently an affection of the mucous mem- branes of the air passages, very much resembling a cold in the head. The dose of it is from two to ten grains ; it should always be given in solution and well diluted, and should also be prescribed in the simplest possible form, on account of its numerous chemical relations with other bodies, many of which decompose it, and form insoluble iodides. Off. Prep.—Liquor Iodinii Compositus; Pilulae Ferri Iodidi; Tinc- tura Iodinii Composita ; Unguentum Iodinii Compositum. Potassii Sulphuretum. Sulphuret of Potassium. Hepar. Liver of Sulphur. Preparation.—Take of Sulphur an ounce; Carbonate of Potassa two ounces. Rub the Carbonate of Potassa, previously dried, with the Sul- phur ; melt the mixture in a covered crucible over the fire ; then pour it out on a marble slab, and as soon as cold, break it into pieces, and put them into a well stopped bottle.— U. S. History.—By the above process a mixture is obtained of tersulphuret of potassium with sulphate of potassa. On the application of heat to the mixture, the carbonic acid of the carbonate is expelled. We may sup- pose, in this operation, that ten equivalents of sulphur react on four of potassa. Of the potassa, three equivalents are decomposed and con- verted into three of oxygen and three of potassium. These latter three 1198 Pharmacy. combine with nine equivalents of the sulphur, and form three equivalents of tersulphuret of potassium. The remaining equivalent of sulphur is converted into sulphuric acid by the action of the three equivalents of oxygen, and sulphate of potassa is formed by the combination of this gas with the undecomposed equivalent of potassa. The best formula for the preparation of sulphuret of potassium is that of M. Henry; he mixes one part of roll sulphur, in powder, with two parts of pure salt of tartar, and places the mixture into flat-bottomed matrasses, each of which should be only two-thirds filled. These are placed on a sand-bath, and heat applied at first gentle, but finally increased, and continued until the whole is thoroughly fused, when it is allowed to cool. The necks of the matrasses must be kept free from any obstruction. The resulting mass is smooth, compact, and of a fine yellow color; it should be placed in well stopped bottles after having been broken into pieces. Sulphuret of potassium is a hard, brittle substance, of a liver-brown color, having a nauseous, bitterish, and alkaline taste, and no odor when dry. When moistened with water it emits a very fetid smell, owing to the disengagement of sulphureted hydrogen. When exposed to the air, it gradually absorbs oxygen, and undergoes a series of changes, result- ing in the formation of sulphate of potassa and free sulphur, and the mass becomes inodorous, and white on its surface. It is soluble in water, forming an orange-yellow solution, with a strong smell of sulphu- reted hydrogen. It is incompatible with the mineral acids which pre- cipitate sulphur, and free sulphureted hydrogen, and with most metallic solutions which are thrown down as sulphurets. Winckler has found specimens of it to consist of tersulphuret of potassium 53.3 parts, hypo- sulphite of potassa 29.5, sulphite of potassa 7, together with a small quantity of sulphate and carbonate. Properties and Uses. — Sulphuret of Potassium is a local irritant, producing in doses of a few drachms dangerous inflammation of the alimentary canal with tetanic spasms; sometimes it acts as an emetic and cathartic. In small doses, and repeated, it is said to increase the temperature of the surface, also the frequency of the pulse, and to aug- ment the secretions, particularly those from mucous membranes. It is likewise antacid, alterative, and antispasmodic, and has been advanta- geously employed in chronic rheumatism and gout, various cutaneous affections, painter's colic, chronic catarrh, asthma, and hooping-cough. Externally, it has been very efficacious in scabies and other cutaneous diseases, in the form of lotion, bath, or ointment. For a lotion, or oint- ment, fifteen to thirty grains of the sulphuret may be dissolved in one ounce of water, or mixed with an ounce of lard—and for a bath the same quantity may be added to each gallon of water. The dose, inter- nally, is from two to ten grains, three or four times a day, in solution with syrup, or given in pill form with liquorice. Pulveres. 1199 PULVERES. Powders. Medicines which have no very unpleasant taste, no corrosive action, which are not deliquescent, and which do not require to be given in very large doses, are the most conveniently administered in the form of powder. When an article is reduced to powder, it has a much greater surface exposed to the action of the air and light, than when in the crude, aggregate mass; and as many, if not all Powders, are more or less injured by the action of these agents, it is always better to keep them in well stopped bottles, and excluded from the action of light, by a coating of black varnish, or by other means. Were druggists to pursue this rule, they would find it very advantageous in many respects. Some agents, notwithstanding even these precautions, lose their virtues rapidly when in the state of powder; such should be pulverized in small quantities at a time, and only as they are required. As a general rule, the finer the Powder, or the longer it is triturated, the more active it becomes. And in the various preparations of the Alkaloids, and Resinoids, care must be taken, in all instances, to triturate for at least nearly half an hour, which renders them much more energetic and effectual in their results. M. Dorvault thinks that the operation of pulverization effects an actual change in the chemical and therapeutical properties of many agents. Sugar is less soluble in water, and less sweet, when long pulverized or triturated—and, he inquires, Is this to be referred to an altered electri- cal condition of the sugar, as the phosphorescence developed during the act of pulverization in the dark would lead us to suppose ? Gum arabic powdered, has not the same taste, nor the same solubility, as when in the entire state. If a given quantity of water may be made to dissolve forty parts of arsenious acid in the vitreous state, the same quantity of water can be made to dissolve only fourteen parts after pulverization. (Annals of Pharmacy, May, 1852.) Changes of this kind may ensue from the action of light, the oxygen of the atmosphere, its nitrogen, or its electricity, etc., upon matter reduced to such a state of fineness that nearly every part of it is exposed to the peculiar agent which effects these changes. Simple powders are those which consist of a single substance; com- pound powders, those containing two or more ingredients mixed together. As the substances entering into the formation of a compound powder may be of various textures and densities, it is generally, preferable to pulverize each article separately, then mix and triturate them together thoroughly. Some articles, however, require the intervention of another before they can be reduced to poAvder, as Camphor, which is pulverized by the addition of a few drops of alcohol; or Camphor and Opium which require the addition of sugar or gum Arabic; others again, are powdered with facility by the aid of a harder substance. Medicines that contain 1200 Pharmacy. a large proportion of fixed oil, or which are deliquescent should never be prescribed in powders, especially Avhen they are to be kept, as the latter are apt to injure the preparation by their moisture, while the former may destroy it in consequence of rancidity. Articles which are incompatible should never be united together, unless the decomposing compound is required. When volatile or deliquescent substances are prescribed in powders, as camphor, carbonate of ammonia, or carbonate of potassa, they should be divided in waxed papers, and inclosed in tin foil, a tin box, or a wide mouthed vial before delivering them. The paper used for powders of ordinary character, should be very smooth, or glazed, to prevent the powder from adhering to it, and sufficiently soft and yielding to be opened or closed readily, without springing so as to throw out any portion of the powder. Some apothecaries fold up their powders in foolscap paper, and these when opened by the patient, in consequence of their stiffness, spill or throw out a very material proportion of the medicine. When a powder is prescribed in bulk, leaving it to the patient to apportion the dose, unless otherwise desired, it should always be put into a wide mouthed vial. The old absurd and unscientific style of combining eight or ten articles in one preparation is fortunately becoming unpopular, and though a few preparations of the kind are retained, yet the major amount of our present compounds consist of but two or three, and never exceeding four substances; in the former, the articles were too frequently thrown together without any guide or rule, or any regard to compatibilities, and though benefit might be derived from these hetero- geneous mixtures, it was always difficult to ascertain upon which article or articles the effect depended, or whether it was owing to a third agent, the result of decomposition. In preparing powders, the proper plan is to dry the article, then beat it in an iron mortar, and after a short trituration, sift it through a fine sieve, and return the coarser parts to the mortar, and repeat this alter- nate pulverization and sifting several times until the process is completed. When very active articles, such as strychnia, chloride of gold, atropia, etc., are to be given in the form of powders—gum, sugar, sugar of milk, starch, or marsh-mallow should be triturated with them, in order to facilitate their reduction to minute division. Light powders may be given in water, gruel, milk, etc.; heavy ones require syrup, molasses, honey, or one of the confections; always bear- ing in mind whether the vehicle be compatible with the active ingredi- ents of the powder. Pulvis Asclepia Compositus. Compound Powder of Pleurisy Root. Preparation.—Take of Pleurisy Root, and Spearmint, each in powder, and Sumach Berries, of each, two ounces; Bayberry Bark and Skunk Cabbage, of each, in powder, one ounce; Pulverized Ginger half an ounce.

Properties and Uses.—This preparation will be found very beneficial in dyspepsia, attended with acidity of the stomach, loss of appetite, constipation or diarrhea, and distress at the stomach after eating. It will prove useful in all derangements of the digestive functions where acidity of the stomach is present. The dose is a teaspoonful in water or Indian meal gruel, three or four times a day. If cream of tartar one ounce, be substituted for the Bicarbonate of Soda, it will form an excel- lent laxative powder for piles.—J. K. Pulvis Cypripedii Compositus. Compound Powder of Yellow Ladies Slipper. Nerve Powder. Preparation.—Take of Yellow Ladies Slipper Root, Pleurisy Root, Skunk Cabbage Root, and Scullcap, of each, in powder, one ounce. Mix them. Properties and Uses.—This powder is useful to allay irritability or excitability of the nervous system, to relieve spasms, and to produce sleep in restless, wakeful, or excited conditions. When acidity of the stomach is present, it is common to add Bicarbonate of Soda, an ounce. The dose is from half a drachm to a drachm three times a day, or as required; it is usually administered in tea or water.—J. K. Pulvis Hydrastis Compositus. Compound Powder of Golden Seal. Preparation.—Take of Golden Seal, Blue Cohosh, and Helonias, each, in powder, half an ounce. Mix together. 76 1202 Pharmacy. Properties and Uses.—This powder is tonic and antispasmodic. It will be found very efficient in dyspepsia, chronic inflammation of the mucous membrane of the stomach, and will afford much relief in cases of distress of the stomach after eating, and in aphthous inflammations of the mouth. It may also be administered to prevent a relapse, in bilious colic. The dose is from half a drachm to a drachm, three or four times a day, in water, tea, or wine, as the case may require.__J. K. Pulvis Hydrastini Compositus. Compound Powder of Hydrastin. Preparation.—Take of Hydrastin, Cornin, and Myricin, of each one scruple. Mix together and divide into twenty powders. Properties and Uses.—Stimulant, tonic, and exerting an influence on mucous membranes. It will be found useful in chronic gastritis, and some forms of dyspepsia, jaundice, etc. The dose is one powder, every two, three, or four hours, as the case may require. It will also be found an excellent tonic during convalescence from exhausting dis- eases.—R. S. N. Pulvis Ipecacuanha Compositus. Compound Powder of Ipecacuanha. Preparation.—Take of Pleurisy Root, Blood Root, Ipecacuanha, Nitrate of Potassa, of each, in powder, one drachm. Mix them. Properties and Uses.—This powder has both diuretic and diaphoretic effects upon the system; it is useful in febrile and inflammatory diseases, and especially in cases where, from idiosyncracy or other causes, opium is inadmissible. The dose is ten or fifteen grains every hour or two. Pulvis Ipecacuanha et Opii Compositus. Compound Powder of Ipecacuanha and Opium. Diaphoretic Powder. Preparation.—Take of Opium, in powder, half a drachm; Camphor, in powder, two drachms; Ipecacuanha, in powder, one drachm; Bitartrate of Potassa one ounce. Mix them. Properties and Uses.—This powder is a valuable anodyne and dia- phoretic, and is perhaps, superior to any other preparation in its dia- phoretic effects upon the system. It is of great efficacy in all febrile and inflammatory diseases, diarrhea, dysentery, cholera morbus, gout, rheumatism, after-pains, all cases of nervous irritability or excitement, and wherever an anodyne combined with a diaphoretic is required. It promotes perspiration without increasing the heat of the body. The above is the original formula, but practitioners vary in preparing it according to their favorite views; thus some omit the cream of tartar and substitute nitrate of potassa, or bicarbonate of soda, while others omit the opium, substituting in its place lactucarium, or twice the quantity of cypripedin. Dose, three to five grains every three or four hours in febrile or inflammatory diseases; and in some cases, ten grains, three times a day. Its action may be materially promoted as a dia- phoretic by warm drinks, such as catnip, balm, or sage tea, lemonade, Pulveres. 1203 etc., which, however, should not be given immediately after the admin- istration of the powder, lest vomiting be provoked. In rheumatism, pneumonia, cerebral affections, hepatic disease, etc., it is frequently combined with small doses of podophyllin. In preparing the powder, the Camphor must first be reduced to powder by trituration with a few drops of alcohol, then add a small portion of the Bitartrate of Potassa, continue the trituration until the Camphor has been still further divided, add the Opium in powder, then the Ipecacuanha, and lastly, the remainder of the Bitartrate, and tritu- rate all together for fifteen or twenty minutes.—N. Smith. Pulvis Jalapa Compositus. Compound Powder of Jalap. Anti- bilious Physic. Preparation.—Take of Alexandria Senna, in powder, two pounds; Jalap, in powder, one pound; Cloves or Ginger, in powder, two ounces. Mix them. Properties and Uses.—This forms an excellent purgative, useful in nearly all cases where such action is required. It combines power with mildness, and acts throughout the whole alimentary canal, cleansing it of all abnormal accumulations, and stimulating the whole biliary appara- tus to healthy action. It may be given to either sex, and at all ages; and is used in all febrile, inflammatory or chronic diseases, being contra- indicated in severe gastric or intestinal inflammation, and requires to be used cautiously and in moderate doses, during pregnancy, menorrhagia, and certain other diseases. Dose, one drachm, put into a gill of boiling water, and allowed to stand till cold, then sweeten if desired, stir, and drink the whole contents. Milk, wine, cider, lemonade or coffee, etc., may be substituted, in proper cases, for the water. In febrile diseases its utility will be much increased by adding about ten grains of bitar- trate of potassa to each dose. Pulvis Leptandrini Compositus. Compound Powder of Leptandrin. Preparation.—Take of Leptandrin, in powder, one drachm; Podo- phyllin, in powder, half a drachm; Sugar of milk five drachms. Mix, and triturate well together. Properties and Uses.—This preparation is a cholagogue cathartic, of immense benefit in epidemic dysentery, in doses of eight grains, re- peated every hour or two, until it operates freely; after which it may be given two or three times a day. It may likewise be used with advantage in typhoid, remittent, and intermittent fevers, with or without the addition of sulphate of quinia, also in all biliary derangements. The addition of three grains of Santonin to each dose, and given twice a day, forms an admirable anthelmintic.—/. K. Pulvis Lobelia Compositus.—Compound Powder of Lobelia. Emetic Powder. 1204 Pharmacy. Preparation.—Take of Lobelia, in powder, twelve ounces; Bloodroot and Skunk Cabbage, in powder, of each, six ounces; Ipecacuanha eight ounces; Capsicum, in powder, two ounces. Mix them. Properties and Uses.—This forms an excellent emetic, and may be used in all cases where an emetic is indicated; it vomits easily and promptly, without causing cramps, or excessive prostration. The dose is two drachms, one fourth of which (half a drachm) must be given every fifteen minutes, in an infusion of boneset. Warm boneset drank freely during the time of taking it, will very much facilitate its operation; and it will also be found that, in many cases, temperate water (at 60°) will be equally as effective in assisting the induction of emesis as the infu- sion, and much more agreeable.—J. K. Pulvis Myrica Compositus. Compound Powder of Bayberry. Ceph- alic Powder. Preparation.—Take of Bayberry Bark and Bloodroot, of each, in powder, one ounce. Mix them. Properties and Uses. This powder is used either alone or combined with an equal part of common snuff, as a snuff in catarrh, headache, polypus, etc. In obstinate affections of the nasal mucous membrane, it is frequently combined with Sesquicarbonate of Potassa one or two drachms, and Golden Seal, half an ounce. Pulvis Nigrum. Black Powder. Emmenagogue Powder. Preparation. — Take of Flowers of Sulphur, Myrrh, Steel Filings, Loaf Sugar, of each, in fine powder, four ounces; White Wine two pints.

Pulveres. 1205 Preparation.—Take of Podophyllin four grains; Bitartrate of Po- tassa three drachms. Mix intimately together. Properties and Uses.—This is an active hydragogue, and is frequently employed in dropsy, obstructed menstruation, etc. (It is employed in place of the old Compound Powder of Mandrake, which was composed of equal parts of Powdered Mandrake Root, Cream of Tartar, and Spearmint, and which was given in doses of a drachm.) Dose, one scruple ; administered every two hours, until it operates sufficiently. The addition of about one or two grains of Capsicum to each dose, will render it much more speedy in its operation. Pulvis Quinia Compositus. Compound Powder of Quinia. Preparation. — Take of Sulphate of Quinia, Ferrocyanuret of Iron, each, one drachm. Mix thoroughly together. Properties and Uses.—This powder is tonic, febrifuge, and antiperi- odic. It is much employed by Eclectic practitioners in febrile and inflammatory diseases, and in all diseases in which there is the least ten- dency to periodicity. As a tonic it is either used alone, or frequently in combination with other tonics, as hydrastin, cornin, etc. The dose is from three to six grains of the powder, repeated two, three or four times a day, according to symptoms. It was introduced to the profession as an agent in the above diseases, by Prof. I. G. Jones, of Columbus, Ohio. Pulvis Rhei Compositus. Compound Powder of Rhubarb. Neutral- izing Powder. Preparation.—Take of Rhubarb, Bicarbonate of Potassa, and Pep- permint Leaves, each, in powder, one ounce. Mix together.

Preparation.—Take of Sulphate of Iron, in powder, two ounces; Alum, in powder, one ounce. Mix them, and calcine by a red heat, as named for Red or Styptic Powder, under the head of Sesquioxide of Iron, which see. When cold, pulverize the mass, and keep it in well stopped bottles. Properties and Uses.—This powder is styptic, and is frequently em- ployed in the treatment of external hemorrhages, and bleeding piles, either alone, or in combination with stramonium ointment, poke ointment, oil of fireweed, etc. Given internally, in doses of three grains, combined with Capsicum one grain, it has proved effectual in passive hemorrhages from the lungs and uterus. 1206 Pharmacy. Pulvis Xanthoxylini Compositus. Compound Powder of Xan- thoxylin. Preparation. — Take of Xanthoxylin, Hydrastin, and Sulphate of Quinia, each, one drachm; Sugar of Milk a sufficient quantity. Mix together, adding just enough Sugar of Milk to form a powder, and then divide into sixty powders. Properties and Uses.—This is a most valuable stimulating tonic, and alterative, and may be employed in all cases requiring such actions. As in debility of the digestive functions, dyspepsia, convalescence from fevers, diarrhea, and dysentery, hepatic torpor, periodical headache, scrofula, and other chronic diseases accompanied with excessive debility. The dose is one powder, to be repeated three or four times a day; it may be given in water, milk, molasses, syrup, or wine, as symptoms may ndicate. One powder contains a grain, each, of xanthoxylin, quinia, and hydrastin.—J. K. QUINIA. Preparations of Quinia. Quinia is one of our most valuable remedies, and is obtained from the Yellow Peruvian Bark ; the pure Quinia is seldom used ; but its Salts are more generally employed, especially those a description of which immediately follows. The Acetate, Ferrocyanuret, Nitrate, Muriate, Lac- tate, Citrate, Iodide, and Phosphate, have also been employed and recom- mended ; but none of them has yet gained a standard reputation. The Ferrocyanuret of Quinia is made by boiling together two parts of Sulphate of Quinia, and three of Ferrocyanuret of Potassium in a very little Water, pouring off the liquor from a greenish-yellow substance of an oily consistence which is precipitated, washing the latter with Dis- tilled Water, then dissolving it in strong Alcohol at 100° F., filtering immediately, and afterward evaporating the solution. The Tannate of Quinia may be prepared by precipitating the Infusion of Bark, or Solu- tion of Quinia, by the Infusion of Galls or Solution of Tannic Acid, and then washing and drying the precipitate. The other above named Salts of Quinia may be prepared by saturating a Solution of the Acids respectively with Quinia, and evaporating the solutions. Either of these Salts may be given in the same doses as the Sulphate. The Iodide of Quinia is obtained by adding a Solution of twenty-four parts of Iodide of Potassium in eight of Water, by drops, to a strong Solution of twenty parts of Bisulphate of Quinia. Wash the precipitate quickly, and dry it in the shade. It is tonic, alterative, and resolvent, and has been found of efficacy in scrofulous enlargements of the glands, in doses of from half a grain to two grains. Or it may be made by decomposing a Solu- tion of one equivalent of Muriate of Quinia with a Solution of four quivalents of Iodide of Potassium. When dry, Iodide of Quinia thus Quinia. 1207 prepared, has the properties of a resin, is easily reduced to a white, ino- dorous powder, extremely bitter, and permanent in the air. It is very soluble in Water, Alcohol, or Ether, forming clear and colorless solu- tions, which deposit the Iodide of Quinia on evaporation. Concentrated Sulphuric and Nitric Acids, and Chlorine, decompose it instantly, with elimination of Iodine. Off.

Sulphate of Quinia. Preparation.—Take of Yellow Calisaya Bark, in coarse powder, four pounds; Muriatic Acid three fiuidounces ; Lime, in powder, five ounces ; Water five gallons; Sulphuric Acid, Alcohol, Animal Charcoal, each, a sufficient quantity. Boil the Bark in one-third of the Water, mixed with one-third of the Muriatic Acid, and strain through linen. Boil the resi- due twice successively, with the same quantity of Water and Acid as before, and strain. Mix the decoctions, and, while the liquor is hot, gradually add the Lime, previously mixed with two pints of Water, stir- ring constantly until the Quinia is completely precipitated. Wash the Precipitate with Distilled Water, and, having pressed, dried, and pow- dered it, digest it in Boiling Alcohol. Pour off the liquor, and repeat the digestion several times, until the Alcohol is no longer rendered bitter. Mix the liquors, and distil off the Alcohol, until a broAvn, viscid mass remains. Upon this substance, removed from the vessel, pour about half a gallon of Distilled Water, and, having heated the mixture to the boiling point, add as much Sulphuric Acid as may be necessary to dis- solve the impure alkali. Then add an ounce and a half of Animal Charcoal, boil for two minutes, filter the liquor while hot, and set it aside to crystallize. Should the liquor, before filtration, be entirely neu- tral, acidulate it very slightly with Sulphuric Acid ; should it, on the contrary, change the color of litmus paper to a bright red, add more Animal Charcoal. Separate the crystals from the liquor, dissolve them in Boiling Water slightly acidulated with Sulphuric Acid, add a little Animal Charcoal, filter, and set aside to crystallize. Wrap the crystals in bibulous paper, and dry them with a gentle heat. The Mother Waters may be made to yield an additional, quantity of Sulphate of Quinia by precipitating the Quinia with Solution of Ammonia, and treat- ing the precipitated alkali with Distilled Water, Sulphuric Acid, and Animal Charcoal, as before.— U. S. History.—In this process the Yellow Calisaya Bark is employed in preference, on account of its containing a greater proportion of Quinia than the other barks, and holding it in combination with less Cinchonia. As found in the bark, the quinia is united with kinic acid, and very pro- bably one or more coloring principles. As water will not take up all the 1208 Pharmacy. quinia of the bark, muriatic acid is added in excess, at least as far as relates to the quinia, and a soluble muriate is formed, mixed with several impurities. After the several decoctions have been mixed and filtered, lime is added, which decomposes the muriate of quinia, combining with its acid to form muriate of lime, while the quinia, being insoluble, is precipitated, leaving most of the impurities in solution with the water; any excess of lime is also thrown down with the quinia. The precipitate is next washed to separate from it all soluble impurities, and is then digested in alcohol which dissolves the quinia, and separates it from its insoluble impurities; after which, by concentration, an impure, brown, viscid quinia is obtained. This is subjected to the action of boiling dis- tilled water, acidulated with sulphuric acid, and the officinal sulphate or disulphate of quinia is formed. The animal charcoal added at this period of the process, facilitates the crystallization of the sulphate of quinia as the solution cools, by its carbonate of lime neutralizing a portion of the sulphuric acid. The solution must not be completely neutralized, but hold the acid very slightly in excess, lest the crystallization ensue before filtration is completed. The solution and re-crystallization of the sul- phate, is for the purpose of obtaining it colorless ; which frequently cannot be effected until after a third solution and re-crystallization. In drying the crystals a gentle heat should be employed, that they may not effloresce. The sulphate of cinchonia remains in solution in the mother liquors. M. Calvert states that there is no certainty in the proportion of sul- phate of quinia when obtained from bark by the solvent action of muri- atic acid, and the precipitant influence of lime ; as a solution of chloride of lime, as well as lime-water, dissolves quinia. Consequently, all the quinia is not precipitated, especially when the lime is added in excess. To obviate this, and obtain a thorough precipitate of the quinia, he first neutralizes the excess of acid by carbonate of soda, and then precipi- tates by caustic soda; quinia not being soluble in this alkali. The aver- age product of quinia obtained from calisaya bark is from one to three per cent. By the above process, sulphate of quinia may be obtained from any of the Peruvian barks ; but, with the exception of the calisaya, all the other varieties will afford a large proportion of Sulphate of Cinchonia held in solution by the mother waters, after the crystallization of the quinia. Sulphate of Quinia is in the form of a loose mass of interlaced, filiform, slightly flexible, silky crystals, sometimes grouped in small stellated tufts, of a snow-white color, inodorous, and possessing a pure, most intense, bitter taste. Exposed to the air, they lose about three-fourths of their water of crystallization by efflorescence. At the temperature of 212°, they become luminous, especially when rubbed; at about 240°, they ■ ielt, presenting a waxy appearance; and at a red Quinia. 1209 heat they are charred, and gradually entirely dispersed. Sulphate of quinia requires 740 parts of water at 54° F., to dissolve it, forming an opalescent solution; and 30 parts at 212°, the latter depositing it in crystals, on cooling. It is scarcely soluble in ether, but dissolves in about sixty parts of alcohol of sp. gr. 0.835. When the water is acidulated with sulphuric acid, it dissolves much more readily. It is dissolved with facility by the diluted acids, and even oxalic and tartaric acids in excess. If to a concentrated solution of sulphate of quinia, as much sulphuric acid be added as enters into its constitution, (or an additional equivalent) a neutral sulphate of quinia is obtained by concentration and crystallization ; rhombic prisms are formed, consisting of one equivalent of quinia, one of sulphuric acid, and eight of water. These are soluble in their own water of crystallization at 212°, and in eleven parts of Avater at 54° F.; they are also soluble in diluted, and less so in absolute alco- hol. They constitute the proper sulphate of quinia, and were formerly incorrectly called Bisulphate, or Supersulphate of Quinia. The officinal sulphate, is a disulphate of quinia, which is the only one employed me- dicinally. It consists, in the form of crystals, of two equivalents of quinia 324, one of sulphuric acid 40, and eight of water 72=436, (2NC20 H12, O2 SOa). Sulphate of Quinia is incompatible with the alkalies, their carbonates, and alkaline earths which decompose it. Its aqueous solution has a peculiar blue tint by reflected light; potassa, soda, or ammonia added to it, yields a white precipitate of quinia ; tannic acid, or astringent infu- sions containing tannic acid, furnish a white precipitate of insoluble tannate of quinia. The soluble salts of baryta and lead occasion preci- pitates. When a fresh solution of chlorine is added to it, and then water of ammonia, an emerald-green color is obtained, together with a gradual deposition of a green color. If a concentrated solution of ferro- cyanuret of potassium be substituted for the ammonia, a dark-red color is produced, which after several hours, gradually becomes converted into a green. A solution of cinchonia is not thus acted upon. The high price of Sulphate of Quinia has led to various adulterations. The most common of which are: the fraudulent additions of sugar, sul- phate of lime, mannite, starch, stearin, margarin, caffein, salicin, sul- phate of cinchonia, etc. Sulphate of cinchonia may be detected as follows, even in the smallest quantity : Take 38 grains of the suspected sulphate of quinia, and introduce it into a flask with half an ounce of solution of ammonia; agitate them well, and allow the mixture to repose twenty-four hours. Then by means of a water-bath, heat it, until the excess of ammonia has been almost completely driven off; allow it to cool, and add one ounce of pure ether. By agitation the quinia is quickly and completely dissolved, and by rest the contents of the flask consists of two transparent liquids, the loAver containing sulphate of ammonia, the upper quinia dissolved in ether, if the salt be pure ; but 1210 Pharmacy. if it contain sulphate of cinchonia, there will be an intermediate stratum betAveen the two liquids of insoluble cinchonia. Sulphate of Cinchonia is best detected by dissolving the salt in forty parts of boiling water, which on cooling will deposit most of the sulphate of quinia, but retain most of the salt of cinchonia—and by concentrating the residual solution, the latter is obtained in short rhombic prisms, or pearly scales — forms which are never assumed by sulphate of quinia. Many of the above adulterations may be ascertained by remarking the degree of solubility of the sulphate in different menstrua, as well as its chemical actions Avith substances above described. Sulphate of quinia is entirely dissipated by exposure to a red-heat, and if any substance remains behind it is sulphate of lime, or some mineral substance. Fatty matters, when present, are not wholly soluble in acidulated water ; starch and gum are not dissolved by alcohol. Sugar, or mannite, may be known by the sweet taste imparted to the residuum remaining after evaporation of the watery solution, — this having been, previous to its evaporation, deprived of its quinia by precipitation with an alkaline car- bonate and filtration. Salicin is discovered by cold concentrated sul- phuric acid forming with the suspected salt a red instead of a colorless solution. If this acid solution is brown or black, it indicates starch, sugar, fatty matters, or other organic substances. Pelletier states that unless the salicin exceeds one-tenth of the amount, this change of color does not ensue ; and consequently when less than this proportion, the salicin must be separated as follows : Add six parts of concentrated sulphuric acid to one part of the suspected salt, and to the resulting brown liquid, add 125 parts of water. The salicin separates, and by filtration may be obtained in the form of a white bitter powder, which becomes bright-red by contact with sulphuric acid. Caffein is difficult to detect, though it changes, the solubility of the salt in different men- strua. A volatile ammoniacal salt may be known by the ammoniacal odor evolved upon the addition of potassa. The purity of sulphate of quinia may be determined by the following method of the Edinburgh College : "A solution of ten grains in a fluidounce of distilled water and two or three drops of sulphuric acid, if decomposed by a solution of half an ounce of carbonate of soda in two waters (twice its weight of water), and heated till the precipitate shrinks and fuses, yields on cooling a solid mass, which when dry weighs 7.4 grains, and in powder dissolves entirely in solution of oxalic acid." Christison states that though this test is sufficient for most impurities, it will not answer where the adul- teration is caffein or sulphate of cinchonia. He also gives the following convenient test for determining its purity: "Twenty parts of boiling- water acidulated with sulphuric acid dissolve it entirely and without any floating oily globules appearing, if there be no fatty matter present; the solution when cold, does not become blue with tincture of iodine if free of starch ; it does not precipitate with oxalic acid if free of lime ; and Quinia. 1211 when treated with solution of baryta so long as a precipitate forms, which precipitate is a mixture of quinia and sulphate of baryta, the liquid has not a sweet taste, if free of sugar or mannite." Properties and Uses. — Sulphate of Quinia is febrifuge, tonic, and antiperiodic. Small doses frequently repeated, strengthen the pulse, increase muscular force, and invigorate the tone of the nervous system. In some persons it induces headache, sickness, or irregular action of the bowels—which effects are generally obviated by combining it Avith mor- phia, extract of stramonium, or both ; and these effects will be almost certain to follow if gastro-enteritic irritation pre-exists. Large doses, as one scruple, or half a drachm, produce many unpleasant symptoms, and ought never to be used ; among these may be named sickness and pain at the stomach, giddiness, flushed countenance, palpitation, a sense of distension in the head, intense weighty headache, ringing in the ears, vomiting, numbness in the feet, deafness, blindness, and delirium. The evil results following large doses, or the injudicious administration of quinia has caused many physicians to reject it altogether, in their prac- tice. This is wrong. Quinia is a safe and very superior remedy, in proper hands. As Avell might we reject all active and useful agents, because, when improperly used, they produce deleterious consequences. Again, the quinia, especially that imported into this Western Country for many years past, has been much adulterated with agents calculated to cause the mischief attributed to the salt; and, it must also be remem- bered, that many of the symptoms following the use of quinia, are the legitimate results of disease itself, as an enlarged spleen, a deranged condition of the nervous system, etc., or are the deplorable consequences of a combined mercurial treatment, which has been and still continues to be a fashionable practice in many portions of this section of the country. No sensible or well educated physician will ever object to the proper employment of the pure sulphate of quinia. With many patients, the beneficial influence of this agent will not be observed until Cinchonism has been produced, known by giddiness, a buzzing or ringing in the ears, slight headache, etc.; while with others it produces good effects independent of the production of these symptoms. When taken internally it is absorbed, and may be detected in the sweat and urine. Sulphate of Quinia in Eclectic practice is used in all febrile diseases, without regard to the violence of the fever, or the degree of congestive enlargement of the liver or spleen; it is usually given during the inter- missions or remissions, and in doses sufficient to affect the head, each day,—when for that day its administration is omitted ; but^should there be no apparent remissions, it is then given daily to produce the same influence upon the head, without, as before said, regard to the violence of the fever, etc. Previous to its administration, however, any symp- 1212 Pharmacy. toms of irritability, wakefulness, or restlessness, must first be subdued It is frequently given in these cases, as well as in many other forms of disease, in combination with ferrocyanuret of iron ; and was first intro- duced to the profession, as a safe and efficacious remedy in this class of maladies by Prof. I. G. Jones. In typhus and typhoid fever, it will be found of much service, in conjunction with small doses of Leptandrin or Podophyllin, sufficient to produce a daily alvine evacuation. In febrile relapses, acute rheumatism, neuralgia, dyspepsia, debility, convalescence from most acute and chronic diseases, dysentery, and in all epidemic diseases, and every disease characterized by periodicity, it may be given with every expectation of success. Combined with morphia, I have used it successfully in epilepsy, delirium tremens, and the convulsive diseases of intemperate persons. In dysmenorrhea, in conjunction with extract of stramonium or belladona, and cimicifugin, it proves almost a specific. It is generally contra-indicated during the presence of gastric inflammation, or unusual irritation of the stomach ; though the addition of morphia, in such cases, will sometimes prevent any hurtful conse- quences. As a tonic, sulphate of quinia will be found useful in all diseases connected with an enfeebled state of the system, and especially in the debility resulting from exhausting diseases; in chlorosis, and in anemic conditions it should be given in union with chalybeates. Externally, sulphate of quinia in solution, has formed a valuable application to indo- lent ulcers, buboes, chancres, and chronic mucous inflammations. The dose of it internally, is from half a grain to three grains, repeated every one, two, three, or four hours, as the urgency of the case may require. Large doses are improper. A solution of Sulphate of Quinia may be made by adding twenty grains of the salt to one fluidrachm of Elixir of Vitriol, and when dis- solved, add two fluidounces of water. The dose of this solution is twenty drops every hour, in about half an ounce of water, or syrup of ginger. Another solution may be made by dissolving Sulphate of Quinia, Tar- taric Acid, of each, twenty grains, in two fluidounces of Water. The dose is as above. The acetate, nitrate, phosphate, ferrocyanate, citrate and muriate of quinia, possess similar properties, but are not usually preferred in practice. Off.

Quinia et Morphia Tartras. Tartrate of Quinia and Morphia. Preparation.—Take of pure crystallized Tartaric Acid, dried, one hundred and fifty-six grains; pure Quinia one hundred and sixty-two grains; pure Morphia two hundred and ninety-two grains; Water a suf- ficient quantity. Add the Acid and the Alkalies to the Water, and boil Quinia. 1213 together.

History.—This valuable, non-crystallizable, double-alkaloidal salt is the discovery of my former colleague, Prof. J. Milton Sanders. It is obtained in beautiful transparent scales or plates, holding each alkaloid in its equiv- alent proportion. It is inodorous, having a slightly bitter taste, and is very soluble in water. Properties and Uses.—Tartrate of Quinia and Morphia is a sedative, tonic, and febrifuge, and is useful in all febrile diseases, especially where there is great irritability or excitability of the nervous system, restless- ness, watchfulness, etc.; also in delirium tremens, periodic spasmodic diseases, epilepsy, and wherever a sedative tonic effect is desired. The dose is from a fourth of a grain to a grain, every one, two, or four hours, as the urgency of the case may require. Quinia et Salicinia Tartras. Tartrate of Quinia and Salicin. Preparation.—Take of pure Salicin four hundred and fifty-seven grains; Tartaric Acid, crystallized and dried, one hundred and fifty-six grains; pure Quinia one hundred and sixty-two grains; Water a sufficient quantity. Add the Alkaloids to the Water, and boil together, until they are dis- solved. Evaporate the solution at a low temperature, till it is of the consistence of thick syrup; then spread it in layers on glass or porcelain plates, and dry in the shade. History.—This non-crystallizable, double-alkaloidal salt is likewise the discovery of Prof. J. Milton Sanders. It is, like the previous salt, obtained in scales or pellicles, inodorous, bitter, and possessing in a high degree the activity of both its constituent alkaloids. It is soluble in water. Properties and Uses—Tartrate of Quinia and Salicin is a febrifuge, tonic, and antiperiodic. It possesses an activity which does not belong to its isolated salts, and may be used in all those cases where either quinia or salicin would be indicated. The dose is from one to five grains, every one, two, or four hours. N. B. Professor Sanders has also prepared the corresponding citrates of the above salts, as well as the Ferrocitrates of Quinia, Morphia, and Salicine; prepared by substituting citric acid for the tartaric, and which may be substituted for the corresponding tartrates, if desired, in the same doses, and forms of disease. Quinia Valerianas. Valerianate of Quinia. Preparation. — Take of Muriate of Quinia seven drachms (Dublin weioht); Valerianate of Soda one hundred and twenty-four grains; Dis- tilled Water sixteen fiuidounces. Dissolve the Valerianate of Soda in two ounces of the Water, and the Muriate of Quinia in the remainder, and, 1214 Pharmacy. the temperature of each solution being raised to 120°, but not higher, let them be mixed, and let the mixture be set by for twenty-four hours when the Valerianate of Quinia will have become a mass of silky acicu- lar crystals. Let these be pressed between folds of blotting paper, and dried without the application of artificial heat.—Dub. History.—In this process a double decomposition takes place between the two salts, producing a solution of chloride of sodium, and crystals of valerianate of quinia. This salt may also be made by either of the fol- lowing methods: Add a slight excess of Valerianic Acid to a Concen trated Solution of Quinia, in strong Alcohol; dilute the solution with twice its weight of Water, stir the mixture accurately, and evaporate at a temperature not exceeding 122° F. After the evaporation of the Alcohol, the Valerianate appears in fine crystals, sometimes isolated, at others grouped together, and which increase from day to day. Or it may be procured by double decomposition of Sulphate of Quinia and Valerianate of Lime, each dissolved in weak Alcohol, and then eva- porated. Valerianate of Quinia is in white, acicular crystals, having a power- ful, repulsive odor of valerianic acid, which is quite distinct from that of oil of valerian. It is soluble in cold water, and more readily in hot, being deposited in fine crystals on cooling. In boiling water it fuses into oily globules, and becomes decomposed with dissipation of its valerianic acid; its solution should not be heated above 120°. Alcohol dissolves it. It appears to lose its strength gradually on exposure to the air; and is easily decomposed by mineral and other acids. Properties and Uses.—Valerianate of Quinia is tonic, febrifuge, and sedative, and may be employed similarly with the tartrate of quinia and morphia. It is highly recommended by Prof. I. G. Jones in hemicrania, and in febrile or other diseases, to relieve restlessness, wakefulness, or nervous irritability. The dose is from half a grain to two grains, every two, three, or four hours, according to the nature of the case. Off. Prep.—Pilulae Cimicifugae Compositae. SODA. Preparations of Soda. Soda Bicarbonas. Bicarbonate of Soda. Preparation.—Take of Carbonate of Soda, in crystals, a convenient quantity; break the crystals in pieces, and put them into a wooden box, having a transverse partition near the bottom, pierced with numerous small holes, and a cover which can be tightly fitted on. To a bottle having two tubulures, and half filled with water, adapt two tubes, one connected with an apparatus for generating carbonic acid, and termin- ating under the water in a bottle, the other commencing at the tubulure, Soda. 1215 in which it is inserted, and entering the box by an opening near the bot- tom, beneath the partition. Then lute all the joints, and cause a stream of carbonic acid to pass through the water into the box, until the car- bonate of soda is fully saturated.—Carbonic acid is obtained from marble, by the addition of Dilute Sulphuric acid.— U. S. History.—In this process, the crystals of Carbonate of Soda, placed on a perforated diaphragm, are exposed to the action of carbonic acid. During the progress of the operation, a considerable amount of water is set free, in consequence of the bicarbonate combining with less water of crystallization than the carbonate; hence the necessity of the diaphragm to allow the water to drain off, instead of dissolving the bicarbonate. When the process is finished, the crystals on the diaphragm will still retain their form, but become changed into an opake and porous sub- stance. There are several other methods of preparing this salt, which it is unnecessary to relate here. Bicarbonate of Soda, according to its mode of preparation, is in small, white, opake, irregular scales, or, in minute, colorless, indistinct crystals, or, when prepared by the above formula, in opake, porous masses, of a snow-white color, and composed of numerous, aggregated, crystalline grains. It is permanent in the air, and possesses a saline, slightly alka- line, not unpleasant taste. It is soluble in thirteen parts of temperate water, and in much less at 212°, from the latter of which, it is obtained in minute, hard, white grains, composed of radiated fibers, as it slowly cools. When its solution is heated a little above 120°, carbonic acid gradually passes off from the salt, which becomes converted into sesqui carbonate at 212°. At a red-heat it is converted into an anhydrous carbonate, its water of crystallization, and an equivalent of carbonic acid being expelled. Bicarbonate of soda consists of one equivalent of soda 31.3, two of acid 44.24, and one of water 9=84.54. Bicarbonate of soda is seldom adulterated, its principal impurity being the result of faulty preparation; in consequence of Avhich, probably arising from imperfect saturation with carbonic acid, a greater or less proportion of carbonate of soda is found with it. The presence of the carbonate may be known by the decided alkaline and disagreeable taste imparted; by the solution yielding a white precipitate with sulphate of magnesia; and by a solution in forty parts of water, giving a reddish- brown precipitate with corrosive sublimate, even if only one per cent. of the carbonate be present,—this test causes a slight opalescence only with the pure bicarbonate. When a solution of bicarbonate of soda is not precipitated by chloride of platinum, or when, after supersaturation with nitric acid, no precipitate is occasioned by chloride of barium or nitrate of silver, it shows the absence of potassa salts, and of sulphates and chlorides. Bicarbonate of soda is incompatible with acids, acidulous salts lime-water, muriate of ammonia, and earthy and metallic salts. Sulphate of magnesia does not decompose it. 1216 Pharmacy. Properties and Uses.—Bicarbonate of Soda possesses properties simi- lar to the bicarbonate of potassa, though less actively diuretic; it also resembles the carbonate of soda in its action, but is much less irritatino- and milder to the taste. It is an excellent antacid and antilithic;'and has been used in calculous diseases with predominance of uric acid. When the carbonate of soda is given in these cases, its continued use is liable to induce phosphatic deposits, after the removal of the uric acid, which is not the case with the bicarbonate, especially when taken in car- bonic acid water, which has the power of maintaining the phosphates in solution, even after it has caused the uric acid to disappear. The same remark is applicable to the bicarbonate of potassa. In doses of a grain, dissolved in milk and water, and repeated every five minutes, the bicar- bonate of soda has been used, with apparent advantage, in infantile croup, promoting the expectoration of the false membrane. The dose of this salt for an adult is, from ten to sixty grains, in a glass of carbonic acid water, or common soda water. Soda Powders, or Effervescing Powders are prepared by placing in one paper Tartaric Acid, twenty-five grains; and in another Bicarbonate of Soda thirty grains. When to be used, they are dissolved in separate portions of water, to which some aromatic syrup may be added, and then mixed. Effervescence imme- diately ensues, during which the liquid is to be-drank. It forms a refrigerant and slightly laxative draught, which is very agreeable and refreshing, especially to persons with fe\rer. The effervescence is occa- sioned by the escape of carbonic acid, which is set free from the bicar- bonate by the tartaric acid, which unites with the soda, forming a tar- trate of soda. The Yeast or Baking Powders, which are now sold so extensively throughout the country, are composed of 54.7 parts of crystallized bitar- trate of potassa, in powder ; 22.7 parts of soda-salaeratus, a salt between the carbonate and bicarbonate, as regards its proportion of carbonic acid; and 22.7 parts of starch, of Avhich corn starch is the best. A good baking powder may be made of two and a half parts of bitartrate of potassa, and one part, each, of bicarbonate of soda and starch. Soda Carbonas Exsiccatus. Dried Carbonate of Soda. Preparation.—Take of Carbonate of Soda a convenient quantity. Ex- pose it to heat, in a clean iron vessel, until it is thoroughly dried, stirring constantly with an iron spatula ; then rub it into powder.— U S. History.—Carbonate of Soda consists of one equivalent of base, one of acid, and ten of water; at a moderate heat it undergoes the watery fusion, and a higher heat drives off all the water and leaves a white, opake, porous, anhydrous carbonate, which is easily pulverizable. It consists of one equivalent of base, one of acid, and no water of crystal- lization, Na O+CO2. Dilute sulphuric acid decomposes it, disengaging 40.7 per cent, of carbonic acid. Soda. 1217 Properties and Uses.—Dried or Anhydrous Carbonate of Soda pos- sesses properties similar to the crystallized carbonate. It is antacid and antilithic, and has been highly extolled in calculous affections depending on a morbid secretion of uric acid. Being free from any water of crys- tallization it readily admits of being made into pills ; from a similar cause its dose is less than the crystallized salt. From five to fifteen grains may be administered for a dose, and repeated three times a day; it is best given in the form of pill with soap and aromatics. Off. Prep.—Sodae Bicarbonas. Soda et Potassa Tartras. Tartrate of Potassa and Soda. Tarta- rized Soda. Rochelle Salt. Preparation.—Take of Carbonate of Soda a pound; Bitartrate of Po- tassa sixteen ounces ; Boiling Water five pints. Dissolve the Carbonate of Soda in the Water, and gradually add the Bitartrate of Potassa. Filter the solution, and evaporate until a pellicle forms; then set it aside to crystallize. Pour off the liquor, and dry the crystals on bibulous paper. Lastly, again evaporate the liquor that it may furnish more crystals.— U. S. History.—This salt was discovered by Seignette, an apothecary of Rochelle in 1672, but the mode of preparing it was not made known until in 1731 by Geoffroy. It is a double salt consisting of tartrate of soda combined with tartrate of potassa. It has been prepared in various ways, but is at present made by neutralizing bitartrate of potassa with carbonate of soda; the excess of tartaric acid in the bitartrate is saturated by the carbonate of soda, carbonic acid being given off at the same time, with effervescence. Tartrate of potassa and soda is in the form of beautiful, colorless, and nearly transparent crystals, frequently very large, and having the shape of prisms or half prisms, with six, eight, or ten sides; their primitive form is the right rhombic prism. It is permanent in the air, with the ex- ception of a slight efflorescence in very dry air, has a mild, saline, slightly bitter, not disagreeable taste, dissolves in five times its Aveight of cold, and in much less boiling water, and its solution is neutral to test-paper. Heat causes it to fuse in its water of crystallization, and when increased decomposes it, destroying the tartaric acid, and leaving a mixture of its two alkaline bases in the form of carbonates, with charcoal. Chloride of barium, or a weak solution of nitrate of silver added to its solution, occasions no precipitate, unless sulphates or chlorides are present. It is incompatible with most acids, acidulous salts, except the bitartrate of potassa, acetate and subacetate of lead, the soluble salts of lime and of baryta. Acids decompose it by uniting with the soda, and causing a crystalline precipitate of bitartrate of potassa. It consists of one equiv- alent of tartrate of potassa 113.2, one of tartrate of soda 97.3, and eight of water 72=282.5. Or, two equivalents of tartaric acid 132, one of 77 1218 Pharmacy. potassa 47.2, one of soda 31.3, and eight of water 72=282.5 (2t+ KO+Na 0+8 Aq). It is not subject to adulteration. Properties and Uses.—Tartrate of Potassa and Soda is a mild, cooling purgative, and being more agreeable than most neutral salts, it is espe- cially adapted to those whose stomachs are delicate or irritable. The dose is from two drachms to one ounce, dissolved in eio-ht or ten parts of water. Given in small doses, and frequently repeated, it is absorbed, and instead of- purging, produces alkalinity of the urine. Tavo drachms of tartrate of potassa and soda added to two scruples of bicarbonate of soda, and put up in one (blue) paper, and thirty-five grains of tartaric acid placed in the other (white) paper, forms the gentle aperient known as Seidlitz Powder. Dissolve the contents of each paper, separately, in half a tumbler of water, mix the two solutions, and drink immediately while it is effervescing. Soda Phosphas. Phosphate of Soda. Preparation.—Take of Bone, burnt to whiteness and powdered, ten pounds; Sulphuric Acid six pounds; Carbonate of Soda a sufficient quantity. Mix the powdered Bone with the Sulphuric Acid in an earthen vessel; then add a gallon of Water, and stir them well together. Digest for three days, occasionally adding a little Water to replace that which is lost by evaporation, and frequently stirring the mixture. At the expi- ration of this time, pour in a gallon of Boiling Water, and strain through linen, gradually adding more Boiling Water, until the liquid passes nearly tasteless. Set by the strained liquor, that the dregs may subside, from which pour off the clear Solution, and boil it down to a gallon. To this solution, poured off from the dregs, and heated in an iron vessel, add, by degrees, the Carbonate of Soda previously dissolved in Hot Water, until effervescence ceases, and the phosphoric acid is completely neu- tralized ; then filter the liquor, and set it aside to crystallize. Having removed the Crystals, add to the liquor, if necessary, a small quantity of Carbonate of Soda, so as to render it slightly alkaline. Then alter- nately evaporate and crystallize, so long as any crystals are produced. Lastly, preserve the crystals in a well stopped bottle.— U. S. History.—Bones are composed chiefly of carbonate of lime, gelatin, and phosphate of lime, and when burnt at a full red-heat, the gelatin is decomposed, its carbon becomes gradually consumed, and a white sub- stance called bone-phosphate is left, consisting of phosphate of lime and a small proportion of carbonate, etc. When this bone-phosphate is well pulverized, and subjected to the action of sulphuric acid, decomposition of the carbonate of lime, with effervescence, takes place. The phosphate of lime becomes partially decomposed, phosphoric acid is set free, and all the lime detached from the two salts, combines with the sulphuric acid, forming a precipitate of sulphate of lime. The disengaged phos- phoric acid unites with that portion of the phosphate of lime which has Soda. 1219 not been decomposed, and a solution of the superphosphate of lime is the result. Boiling water is now added for the purpose of separating any sulphate of lime which may remain in the solution, and the whole is strained ; the sulphate, which remains on the strainer, is washed as long as it yields any superphosphate, which may be known by the acid taste of the water passed. The washings and strained solution of super- phosphate of lime, being mixed together, and allowed to rest, a portion of sulphate of lime is precipitated as the liquid cools, and from which it is separated by decantation. The liquid is then concentrated by evapo- ration, which causes a still further deposit of sulphate of lime, which is separated by rest and decantation as before. The concentrated solution of superphosphate of lime is now heated, and a hot solution of carbonate of soda added to saturation. The excess of phosphoric acid in the solution combines with the soda to form phosphate of soda, while the carbonic acid is set free with effervescence; the superphosphate of lime having lost its excess of acid, is precipitated as the neutral phosphate. The liquid being a solution of phosphate of soda, is now filtered to sepa- rate the neutral phosphate of lime, after which it is evaporated and allowed to crystallize. In order to insure a complete precipitation of the neutral phosphate, as well as an entire disengagement of the carbonic acid, both solutions, when added together, should be boiling hot; and if the solution of phosphate of soda thus procured, be slightly alkaline, the crystals will form more abundantly and with greater facility. An economical and expeditious mode for obtaining phosphate of soda, has been given by M. Funcke, a German chemist. It consists in diffus- ing the powdered bone-phosphate in water, adding enough dilute sul- phuric acid to decompose the whole of its carbonate of lime, and when effervescence has ceased, to add nitric acid, which dissolves the phos- phate of lime, and leaves the sulphate. To this nitric solution, sulphate of soda, equal in quantity to the bone employed, is added, and when reaction ceases, the nitric acid may be recovered by distillation. By this process, sulphate of lime and phosphate of soda are generated, which may be separated from each other by the action of water, and the phos- phate crystallized in the ordinary manner. Phosphate of soda crystal- lizes in rhombic prisms terminated by four converging planes; the crystals are large, colorless, and transparent, but soon become opake on account of their speedy efflorescence in the air. They have a cooling, mildly-saline taste, somewhat like that of common salt, and have a slight alkaline reaction. Heat fuses them in their water of crystallization, and if continued the water passes off, leaving only one equivalent of water, which is obstinately retained by every two equivalents of soda. At a red-heat, all the water is expelled, and the salt melts into a limpid globule, which becomes opake on cooling ; in this form it is the pyro- phosphate of soda of Clark, or the diphosphate of Turner. Phosphate of soda is soluble in four parts of cold, and two of boiling water. It is 1220 Pharmacy. not apt to be adulterated, but may contain carbonate of soda, from an excess being added during the process, and which may be known by the effervescence occurring on the addition of an acid. If any soluble sul- phate be present, chloride of barium will precipitate a mixture of sulphate and phosphate of baryta, and which nitric acid will not wholly dissolve; if the precipitate dissolves in nitric acid with effervescence, it is a carbo- nate of baryta, caused by the presence of carbonate of soda. Nitrate of silver will produce a yellow precipitate if a chloride be present, and which precipitate is a mixture of chloride and phosphate of silver, not entirely soluble in nitric acid. Phosphate of soda is incompatible with the soluble salts of lime, which precipitate phosphate of lime, with the magnesian salts, and with neutral metallic solutions. It consists of two equivalents of soda 62.6, one of phosphoric acid 72, and twenty-five of water 225=359.6 (2 Na O+POs +25 HO). If a solution of phosphate of soda be evaporated at 90°, the salt crystallizes with only fifteen, instead of twenty-five equivalents of water. Properties and Uses.—Phosphate of Soda, formerly known a,s Sub- phosphate of Soda, and Sal Mirabile, is a mild, saline cathartic, well adapted to children, and persons with delicate stomachs. The dose is from half an ounce to two ounces, and is best given in gruel or weak broth, to which it imparts a taste as if seasoned with common salt. Off. Prep.—Ferri Phosphas. Soda Valerianas. Valerianate of Soda. Preparation.—Take of Bichromate of Potassa, in powder, nine ounces, (Avoirdupois); Fusel Oil four fluidounces, (Imperial measure); Com- mercial Oil of Vitriol six fiuidounces and a half, (Imp. meas.); Water half a gallon, (Imp. meas.) ; Solution of Caustic Soda one pint, (Imp. meas.), or as much as is sufficient. Dilute the Oil of Vitriol with ten fluidounces of Water, and dissolve the Bichromate of Potassa, in the remainder of the Water, with the aid of heat. When both the Solutions have cooled down to nearly the temperature of the atmosphere, place them in a matrass, and having added the Fusel Oil, mix well by repeated shaking, until the temperature of the mixture, which at first rises to 150°, has fallen to 80° or 90°. The matrass having been now connected with a condenser, heat is to be applied so as to distil over about half a gallon of liquid. Let this, when exactly saturated with Solution of Caustic Soda, be separated from a little Oil that floats upon its surface, and evaporated down until the escape of Aqueous Vapor having entirely ceased, the residual salt is partially liquefied. Now withdraw the heat, and when the Valerianate of Soda has concreted, it is, while still warm, to be divided into fragments, and preserved in a well stopped bottle.— Dub. History.—In this process, Valerianic Acid is formed by the oxidizing action of chromic acid, or of the sulphuric acid and bichromate, on the Strychnia. 1221 fusel oil, and passes over with water ; the solution of caustic soda being then added to it to saturation forms a solution of valerianate of soda, which is obtained in the solid form by evaporation. The oil that floats on the surface of the solution of the valerianate, is valerianate of amylic ether. Fusel oil is converted into valerianic acid by being deprived of two equivalents of hydrogen, while at the same time it gains two of oxygen. Valerianate of soda is a deliquescent salt, having, at first, a styptic taste followed by sweetishness, a valerian odor, and is very soluble in water. It fuses without loss of acid at 285°, and on cooling, becomes a Avhite solid ; it consists of one equivalent of soda 31.3, and one of acid 93=124.3 (Na 0, Cio Hq Os). Properties and Uses.—Valerianate of Soda is not used as a medicine, but for the preparation of the valerianates of iron, quinia, etc., by double decomposition of the soda salt with salts of the respective bases. It might be used with advantage in nervous and irritable habits, attended with acidity of the stomach. Off. Prep.—Quiniae Valerianas. STRYCHNIA. Strychnia. Preparation.—Take of Nux Vomica, rasped, four pounds ; Lime, in powder, six ounces ; Muriatic Acid three fiuidounces; Alcohol, Diluted Sulphuric Acid, Solution of Ammonia, Purified Animal Charcoal, Water, of each, a sufficient quantity. Digest the Nux Vomica in two gallons of Water, acidulated with a fluidounce of the Muriatic Acid, for twenty- four hours ; then boil for two hours, and strain with expression through a strong linen bag. Boil the residuum twice successively in the same quantity of Acidulated Water, each time straining as before. Mix the decoctions and evaporate to the consistence of thin syrup ; then add the Lime previously mixed with a pint of Water, and boil for ten minutes, frequently stirring. Pour the mixture into a double linen bag, and, having washed the precipitate well with Water, press, dry, and powder it. Treat the Powder repeatedly with Boiling Alcohol, until deprived of its bitterness ; mix the liquors, and distil off the Alcohol by means of a water-bath. Mix the residue with Water, and, having applied heat, drop in sufficient Diluted Sulphuric Acid to neutralize and dissolve the Strychnia; then add purified Animal Charcoal, boil for a few minutes, filter, evaporate, and crystallize. Dissolve the crystals in Water, and add sufficient Solution of Ammonia to precipitate the Strychnia. Lastly, dry the precipitate on bibulous paper.— U. S. History.__In the above process the nux vomica is first reduced to a powder in order to be more readily acted upon, and this may be done 1222 Pharmacy. by rasping the seeds, or by exposing them to steam until softened, and then slicing, drying, and grinding them. The strychnia is then extracted by water acidulated with muriatic acid, which forms a solution of muri- ate of strychnia. This is concentrated, and on the addition of lime the salt is decomposed,—an impure strychnia is precipitated, while the chlo- ride of calcium remains in solution. The precipitate is treated with boiling alcohol which takes up the strychnia, and which may be obtained in impure and colored crystals, by concentration of the alcoholic solution. To purify it, sulphuric acid is added to the crystals forming a sulphate of strychnia, while at the same time animal charcoal is employed to decolo- rize it. In the last part of the process ammonia is added to the sulphate of strychnia, which decomposes it, precipitating crystals of strychnia, while the sulphate of ammonia remains in solution. The brucia of the nux vomica, accompanies the strychnia throughout the process, and remains in the solution only when the strychnia is obtained from the alcoholic solution. As brucia is more readily soluble in cold alcohol than strychnia, it would be an improvement upon the above process, to continue the purification by two or more solutions, and crystallizations in alcohol. Or if it be desired to remove the brucia almost entirely, the strychnia obtained may be dissolved in very diluted nitric acid, then fil- tered and concentrated for crystallization. The nitrate of brucia forms short, thick, dense prismatic crystals, grouped together, and the nitrate of strychnia crystallizes in radiated tufts of long, light, silky, capillary needles. On adding water to these, and gently agitating, the strychnia may be poured off, leaving the brucia. The salts may then be dis- solved, separately, in water, and decomposed by ammonia. Strychnia is obtained in great proportion from St. Ignatius' Bean, but on account of its scarcity, the nux vomica seeds are employed. It is also stated that it may be profitably procured from the bark of the nux vomica tree. Strychnia crystallizes in elongated, oblique, colorless octaedres, or quadrilateral prisms with quadrilateral terminations ; when rapidly crys- tallized from the alcoholic solution, it is in the form of a white, granular powder. It is inodorous, with an intense bitterness which may be com- municated to water containing only a 600,000th part of it, is permanent in the air, fusible like a resin, and is completely dissipated by a red-heat. It is soluble in fixed and volatile oils, in 6667 parts of water at 50°, in 2000 at 212°, and in boiling alcohol; it is insoluble in ether or pure alco- hol, and is alkaline in its reactions. The strychnia usually met with is in the form of a grayish-white powder. Strychnia consists of carbon, hydrogen, oxygen, and nitrogen, the proportions of which have been vari- ously given; Liebig and Gerhardt define its composition to be Cw H24 OiN2. If brucia be present in strychnia, the addition of nitric acid reddens it. A concentrated solution of pure strychnia in concentrated sulphuric acid, Strychnia. 1223 becomes of a splendid violet color on the addition of a minute quantity of solution of chromate of potassa. Strychnia may be detected in very minute quantity, by placing a drop of the suspected liquid on glass, and allowing the liquor to evaporate, then to the dry residuum add a drop of concentrated sulphuric acid, or enough to moisten it, and then add a drop of solution of ferrocyanide of potassium (red prussiate of potassa), and mix well together; a fine deep violet color will be immediately pro- duced, which passes slowly into a light brick-red color, and remains for several hours. It may likewise be detected in minute quantity, by rub- bing a little of the alkali with a few drops of concentrated sulphuric acid containing one-hundredth of nitric acid,—the solution will be Avith- out color; but if peroxide of lead be added in the smallest quantity, a magnificent blue color will be at once produced, and which will pass rapidly into violet, then gradually to red, and finally into yellow. Brucia may be obtained from false angustura bark, by a similar pro- cess to that of procuring strychnia from nux vomica, with the exception that the alcoholic extract of the precipitate occasioned by lime or mag- nesia, should be treated with oxalic acid, and then Avith a mixture of rectified alcohol and ether, which takes up the coloring matter, and leaves the oxalate of brucia. This is decomposed by magnesia, and the brucia separated by alcohol, and obtained in cr3Tstals by spontaneous evaporation. Brucia crystallizes in small, delicate, pearly, colorless scales, is inodorous, intensely bitter, permanent in the air, and fusible a little above 212°. It is soluble in alcohol, in 850 parts of cold and 500 of boiling water, sparingly soluble in volatile oils, and insoluble in ether and the fixed oils. It has an alkaline reaction, and like strychnia forms crystallizable salts with acids. Nitric acid reddens it, which becomes yellow by heat, and violet upon the addition of protochloride of tin. Prof. J. Milton Sanders has prepared two salts of strychnia, the citrate and tartrate, which he considers the most efficient form of administra- tion, and as possessing more activity and safety than the pure strychnia. He prepares the Citrate of Strychnia by dissolving with a gentle heat in a sufficient quantity of distilled water, one hundred and ninety-two grains of dried citric acid, and then adding three hundred and forty-six grains of pure strychnia. By gentle evaporation the citrate may be ob- tained in crystals. It is an acid salt, and its constitution is (C12 H» Oii + H2) i (Cu H22N2 O4). That is, one equivalent of the strychnia has displaced one equivalent of the external hydrogen of the citric acid. As it is a tribasic acid, there are still two equivalents of external hydro- gen to be displaced, ere the acid be entirely neutralized. The dose is from one-tenth to one-twentieth of a grain, to be given cautiously till the desired effect is produced. The Tartrate of Strychnia he obtains, by dissolving in a sufficient quantity of Distilled Water, one hundred and fifty-six grains of Tartaric Acid, and then adding three hundred and forty-six grains of Strychnia. 1224 Pharmacy. and evaporating as above. It is also an acid salt with the composition indi- cated by the formula (Cs H± Oio+H) +(Cm H22 N2 04). The dose is the same as the citrate. Properties and Uses.—Nux Vomica and Strychnia act chiefly, if not solely, by stimulating the spinal chord and medulla oblongata, and with- out affecting the functions of the brain. The slightest observable effects from small doses are twitches of the muscles of the arms and legs, occurring especially during sleep, accompanied with restlessness, some anxiety, acceleration of the pulse, and generally slight perspiration. Sometimes the action of the bowels is increased, and the discharge of urine is either augmented, or discharged more frequently—it likewise promotes the venereal appetite. Large doses occasion very violent start- ing of the muscles—even a tendency to lockjaw, succeeded by stiffness, weariness, pain or rending in the limbs. In their highest degree, these effects amount to violent tetanic spasms, occurring in frequent fits, with brief intervals of repose, acute sensibility, and dreadful alarm. Through whatever form or texture Strychnia is introduced into the body, it exerts this action more or less, operating with an energy proportioned to the activity of absorption where it is applied. It is not a cumulative poison like mercury or digitalis ; nor does its activity diminish under the influ- ence of habit, as with opium. There is no known antidote for it; mor- phia is probably the best, as full opiate doses will somewhat arrest these effects. Camphor and sweet oil, have been advised as antidotes, but further investigations are required before they can confidently be relied upon. M. Duclos states that under the application of negative electricity, the poisonous effects of strychnia on animals subside, while under that of the positive they are aggravated. As some patients are powerfully affected by the smallest doses of this agent, too much caution cannot be employed in its administration. I would observe here, that a short time since, a favorite Newfoundland bitch, with three pups about two months old, were poisoned by some evil-minded person, by strychnia placed on meat. One of the pups died in the convulsed condition com- mon to the influence of strychnia; the others were attacked with spas- modic twitchings which continued to increase. From some cause the bitch vomited up her meat, a portion of which was eaten by two chick- ens about six or eight weeks old. To the bitch and the remaining two pups I gave about a gill of sweet oil to each, followed by about four grains of camphor to the mother, and two grains to the pups, in some bread ; they recovered and are doing well. Of the chickens, one was apparently dying, lying on the ground, wings outspread, mouth open, and with frequent spasmodic jerks, the other trembled and spasmodi- cally staggered around like an intoxicated person; to each of these I gave about a grain of camphor in butter, and fastened them up, and in an hour they had both fully recovered. I mention these facts that Syrupi. 1225 further inquiries may be made as regards the antidotal power of camphor in poisoning by strychnia. To determine whether strychnia was the poison administered, the meat vomited by the dogs was carefully exam- ined. Both dogs and chickens were actively purged. The alcoholic extract of Nux Vomica and Strychnia, are more gene- rally employed in medicine; and the action of the former is owing to the strychnia it contains. Strychnia is used in hemiplegia, paraplegia, partial paralysis of particular joints or muscles, and of the bladder. The paralyzed muscles are always first affected, if they are thrown into spasms at all. If the remedy is to succeed, improvement begins speedily. It must not be used in recent cases of palsy, or while general reaction prevails; neither when signs exist either of local irritation in the brain or spinal chord, or of determination of blood to the head. It has been likewise used in neuralgia, epilepsy, ague, amenorrhea, dysen- tery, rheumatism, syphilitic osteocopi, and obstinate constipation. In the treatment of gleet, urethral stricture, and recent enlargement of the prostate, I have found it a superior remedy, used internally and locally. In dyspepsia, where there is a want of appetite, constipation, and a sen- sation of epigastric weight after eating, I have found the combination of one grain of the alcoholic extract of Nux Vomica, well triturated with forty grains of ptelein, and divided into twenty pills, an excellent remedy; likewise in dyspepsia connected with impotence, caused by masturbation or venereal excesses; the dose is one pill, repeated three times a day. Strychnia will also be found advantageous in many uterine diseases, prolapsus uteri, etc. The dose of strychnia is from one-twentieth of a grain to one-tenth, two or three times a day; it may be rendered more soluble in alcohol or water, by the addition of a few drops of an acid, as the acetic, muriatic, nitric, or sulphuric. Its best form of administration is that of pill. Brucia exerts an influence upon the system very similar to that occasioned by strychnia, but is less energetic; its dose is from one-eighth of a grain to half a grain, three or four times a day. In the administration of Brucia and Strychnia, or any of their salts, great caution must be observed, and the patient carefully watched during its use. Off. Prep.—Pilulae Eupurpurini Compositae. SYRUPI. Syrups. Syrups are liquid officinal medicines, of a viscid consistence, produced by the concentrated solution of Sugar alone or Sugar mixed with Honey, in Water, Wine, or Vinegar. Syrups are either Simple or Medicated ; simple syrup is Avhere the solution of the sugar is made with water only; it forms the basis of a great many medicated syrups. Medicated syrups, are those in Avhich one or more medicinal agents enter into the solution, and are commonly prepared by incorporating 1226 Pharmacy. Sugar with Vegetable, Aqueous or Spirituous solutions, expressed Juices etc. When the active principles of the ingredients used are dissi pated or decomposed by boiling, or where they are not readily soluble in water, they are frequently extracted by Diluted Alcohol, the spirituous ingredient of which is either retained, or driven off, as may be required* occasionally they are prepared by adding a Tincture of the medicinal agent or agents to simple syrup, and evaporating the Alcohol. The stability of a Syrup depends mainly on its composition and consistence, the temperature, and the amount of its exposure to the air ; and no ingredients should be admitted into its composition except the active principle required and simple syrup. As most syrups are used in chronic diseases during the absence of febrile or active inflammatory symptoms, the addition of the alcoholic tincture is not objectionable, unless it be in large proportion ; but syrups prepared for febrile or in- flammatory difficulties should be entirely free from any spirituous liquor whatever. The best and most economical plan in making syrups, is to employ only Refined Sugar, as it saves the trouble of subsequent clarification, beside being less liable to undergo change. The quantity of sugar required is about two parts to one of liquid; if it be in too small pro- portion, the syrup will be apt to ferment; if in too large, crystals of sugar will be deposited. The heat employed should be adapted to the character of the active principle ; if it be A'olatile, a gentle heat is re- quired, as well as in cases where a high temperature would decompose it. If it be not injured by heat, concentration should be conducted with a lively fire, and effected as quickly as possible, as in many instances a long continued heat will impair its efficiency. The proper degree of concentration is 30° Baume's saccharometer, when boiling, and 35° when cold ; or specific gravity when boiling 1.261, and when cold about 1.319. After the syrup has cooled, if a pellicle forms upon its surface, it has been concentrated too much. Syrups which contain no volatile principle, or one not injured by heat, may frequently be restored to their original condition, after having undergone vinous fermentation, by again boiling them to expel the alcohol and carbonic acid, and sufficiently concentrating them ; and a syrup thus recovered is less apt to undergo subsequent change, on account of the fermenting principles having been decreased or consumed. Various means have been devised for the pre- servation of syrups : a little sulphate of potassa, chlorate of potassa, or sugar of milk, have been recommended for this purpose. One flui- drachm of Hoffman's Anodyne to the pint of syrup will effectually check a tendency to fermentation. The maintenance of a syrup in a regular degree of temperature, say 55° to 60°, will tend very much to lessen its liability to ferment. As a general rule syrups intended to be kept should be bottled while hot, securely corked and sealed, and after cooling should be shaken that the moisture condensed on the cork Syrupi. 1227 may be mixed with the syrup, and not form a diluted layer at the sur- face. The syrups used in Eclectic practice, which have been prepared according to the method of W. S. Merrell, are found to keep for a long time without undergoing change ; in relation to which he has furnished the following remarks : — Most of the medical syrups should be pre- pared on the same principles as the Fluid Extracts, only they are less concentrated, ;md therefore proportionally less. Alcohol should not be retained in their composition, for, as they are administered in larger doses, the presence of spirit in them would be more appreciable and injurious. All the compounds that have been proposed for syrups in the Eclectic school of practice, such as the Alterative, Scrofulous, and Pulmonary syrups comprise substances AArhose medical principles are imperfectly soluble in water, and should, therefore, be acted on by Alcohol. I make these preparations Avith the same apparatus, and by the same process as I make the Fluid Extracts, thus retaining, most perfectly, all the aroma and volatile essences of the ingredients. Physicians and apothe- caries who have not such apparatus, may substitute the process laid down under the formula for Alterative Syrup, which see. In all these preparations, the principle should be adopted of confining the boiling and evaporation to the weaker portion of the solution, so that those delicate principles which are evaporated or decomposed by heat may be submitted to its action as little as possible. Syrupus (Syrupus Simplex). Syrup (Simple Syrup). Preparation.—Take of refined Sugar two pounds and a half; Water a pint. Dissolve the Sugar in the Water with the aid of heat, remove any scum which may form, and strain the Solution while hot.— U. S. History.—Simple syrup, when properly made, is sweet, inodorous, thick, viscid, colorless and transparent. When made with sugar, not well refined, it is apt to be turbid, and may be clarified by beating the white of an egg to a froth with three or four ounces of water, adding this to the syrup, with about five per cent, of animal charcoal if any peculiar flavor or color be present, boiling the whole for a short time so that the albumen may coagulate, and removing the scum which rises to the surface, either by a skimmer, or by filtration through flannel; this will clarify two gallons of syrup. Properties and Uses.—Syrup is employed in various mixtures, pills, medicated syrups, and extemporaneous prescriptions. qjt, prep.—Pilulae Ferri Compositae; Syrupus Acidi Citrici ; Syrupus Ferri Iodidi; Syrupus Ferri Phosphatis; Syrupus Ipecacuanha; Syrupus Tolutanus. Syrupus Acidi Citrici. Syrup of Citric Acid. Lemon Syrup. Preparation.—Take of Citric Acid, in powder, two drachms; Oil of Lemons four minims; Syrup two pints. Rub the Citric Acid and Oil of 1228 Pharmacy. Lemons with a fluidounce of the Syrup, then add the mixture to the remainder of the Syrup, and dissolve with a gentle heat.— U S. History.—This syrup is more readily prepared than lemon syrup, keeps better, and is more uniform, though not quite so well flavored. Tartaric acid, which is frequently substituted for the citric, is apt to irritate the stomach, and the syrup prepared with it, does not keep so well. A preparation sold as Syrup of Lemons, and which is in no way inferior to the above, is made by adding to one gallon of Water, half a pound of Citric Acid, one pound of Ivory Black, and thirteen pounds of Refined Sugar; boil together, filter, and add one fluidrachm of Oil of Lemon. Properties and Uses.—This syrup added to water, or to carbonic acid water, forms an agreeable and refrigerant beverage for persons laboring under febrile complaints, and in certain states of the system. From a fluidrachm to half a fluidounce may be added to half a pint of the fluid in which it is to be taken. Syrupus Allii. Syrup of Garlic. Preparation.—Take of fresh Garlic, sliced and bruised, six ounces; Diluted Acetic Acid a pint; Refined Sugar, in coarse powder, two pounds. Macerate the Garlic in ten fluidounces of the Diluted Acetic Acid, in a glass vessel, for four days, and express the liquor. Then mix the resi- due with the remainder of the Diluted Acetic Acid, and again express until sufficient has passed to make the whole, when filtered, measure a pint. Lastly, pour the filtered liquor on the Sugar contained in a quart bottle, and agitate till it is dissolved.— U. S. Properties and Uses.—This syrup is useful in chronic catarrhal affec- tions of the lungs, and is particularly beneficial in the cases of infants, on account of the stimulus it affords to the nervous system. The dose is a teaspoonful to a child a year old. The active matter of garlic is more readily taken up by vinegar than water. A syrup of onions is often prepared extemporaneously for coughs, by slicing one or two onions, and laying the slices upon each other with sugar between; this is set by the fire in a saucer or glass vessel, and kept there, until the juice of the onion and the sugar have, by the aid of the heat, formed a syrup in the vessel. It may be given freely. Syrupus Aralia Compositus. Compound Syrup of Spikenard. Pul- monary Balsam. Preparation.—Take of the Roots of Spikenard, Elecampane, Comfrey, and Bloodroot, of the Leaves and Flowers of Horehound, and of the Bark of Wild Cherry, each, one pound. 1. Grind and mix the articles together; place the whole six pounds in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for three days. Then transfer the Avhole to a displacement apparatus, and gradually add Hot Water, until three pints of the Alcoholic tincture have been obtained, Syrupi. 1229 which retain and set aside. 2. Then continue the percolation, and of this second solution reserve so much as contains a sensible amount of Spirit, and distil or evaporate the Alcohol from it. 3. Continue the displacement by Hot Water, until the solution obtained is almost tasteless, and boil down this weaker infusion until, when added to the second solution after the evaporation of its Alcohol, it will make eighteen pints. 4. To these two solutions combined, add twenty-four pounds of Refined Sugar, and dissolve it by heat, carefully removing any scum which arises as it comes to the point of boiling; and if it exceeds twenty-one pints, evapo- rate to that quantity with constant stirring. Then remove from the fire,- and when nearly cold, add the three pints of Alcoholic Tincture first obtained and set aside, and make three gallons of Syrup. Each pint will contain the virtues of four ounces of the ingredients. Properties and Uses.—This is an elegant remedy for obstinate coughs of long standing, and pulmonary affections generally. It is often employed advantageously in pulmonary and bronchial difficulties com- bined with one-fourth part of Fluid Extract of Queen's Root. The dose of the syrup is half a fluidounce three or four times a day. Syrupus Assafc3tida. Syrup of Assafetida. Preparation.—Take of Assafetida an ounce ; Boiling Water a pint; Sugar two pounds. Triturate the Assafetida in a mortar with a portion of the Boiling Water until a uniform paste is formed, then gradually add the remainder of the Water, strain and add the Sugar, dissolving it with a gentle heat. History.—Good assafetida contains nearly six per cent, of volatile oil, which would be dissipated were much heat employed in the solution of the sugar. The object of employing boiling water instead of cold, is to have more of the gum-resin taken up, and which is permanently dissolved or suspended by the sugar. This syrup is nearly white Avhen first made, but gradually assumes a pinkish tinge; it is quite permanent, keeping for several months without any material change, and has the advantage of being entirely free from alcohol, which is often objectionable. Properties and Uses.—This is an excellent form for the administration of assafetida, being less stimulant than the tincture, and more prompt in its action than the pill. The dose is one or two tablespoonfuls, repeated three or four times a day. If used in enema, two to four fluidounces may be injected into the rectum at one time. Other Anti- spasmodics may be combined with it, as fluid extracts of Black Cohosh, Blue Cohosh, Ladies Slipper Root, Scullcap, Valerian, etc., according to indications. Syrupus Cinnamomi. Syrup of Cinnamon. Preparation.—Take of Tincture of Cinnamon four fiuidounces; Water three pints; Refined Sugar seven pounds and a half; Essence of Cinna- 1230 Pharmacy. mon (Tincture of the Oil,) four fiuidrachms. Mix the Tincture with three pounds of the Sugar in a shallow dish, and evaporate the Alcohol with the aid of a gentle heat, or allow it to evaporate spontaneously; then add the remainder of the Sugar, and dissolve it in two pints and a half of the Water. With the remaining half pint of Water, beat up the Avhites of two Eggs, add it to the Syrup, boil for one or two minutes, strain through a Canton flannel bag, and when nearly cool add the Essence of Cinnamon. Properties and Uses.—This syrup is a warm aromatic stomachic, car- minative, and astringent. It is chiefly used as an adjuvant to other less pleasant medicines, especially in the treatment of diarrhea, dys- entery, hemorrhages, and Avhere astringents are indicated. It may be given in doses of one or two fluidrachms. Syrupus Cochlearia Compositus. Compound Syrup of Horseradish. Preparation.—Take of the recent Root of Horseradish, grated, two ounces; Boneset, Leaves and Tops, one ounce; Canada Snakeroot half an ounce; Boiling Water, Diluted Acetic Acid, of each, a sufficient quantity; Refined Sugar two pounds. Infuse the Boneset and Canada Snakeroot, in half a pint of the Boiling Water, and express with strong pressure, adding Boiling Water to the mass until half a pint of infusion is obtained; then add the Sugar and dissolve by gentle heat. Add the Horseradish to Dilute Acetic Acid, half a pint; let it stand for two days, and then express, adding Dilute Acetic Acid to the mass until half a pint of the Acetous Solution is obtained. Add this to the above Syrup, and agitate until all the Sugar is dissolved. Properties and Uses.—This forms an efficient preparation for obstinate colds, catarrhs, hoarseness, and chronic irritation of the throat and fauces. The dose is from one to four fluidrachms, every two or three hours. The following compound, known as " Cough or Vegetable Elixir," has been found a most beneficial agent in chronic pulmonary affections, cough, etc. To one gallon of good cider vinegar, add half a pound, each, of Balsam of Tolu and gum Arabic, dissolve by heat, and add of Refined Sugar six pounds; when all is dissolved, remove from the fire, and add of Tincture of Opium, eighteen fluidounces. The dose of this is a teaspoonful three, four, or five times a day, or whenever the cough is severe. Sometimes molasses may be substituted for the sugar, or honey. Syrupus Corydallis Compositus. Compound Syrup of Turkey Corn. Preparation.—Take of the Root of Turkey Corn, coarsely bruised, two pounds; the Leaves of Twin-leaf one pound; Blue Flag Root one pound; Sheep Laurel Leaves half a pound. 1. Mix the articles together; place the whole four pounds and a half in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for three days. Then transfer the whole to a displacement apparatus, and gradually add Syrupi. 1231 Hot Water until two pints and four fluidounces of the Alcoholic Tincture have been obtained, which retain and set aside. 2. Then continue the percolation, and of this second Solution reserve so much as contains a sensible amount of Spirit, and distil or evaporate the Alcohol from it. 3. Continue the displacement by Hot Water, until the Solution obtained is almost tasteless, and boil down this weaker infusion until, Avhen added to the second Solution after the evaporation of its Alcohol, it will make thirteen pints and a half. 4. To these two Solutions combined, add eighteen pounds of Refined Sugar, and dissolve it by heat, carefully removing any scum which arises as it comes to the point of boiling; and if it exceeds fifteen pints and twelve fluidounces, evaporate to that quantity with constant stirring. Then remove from the fire, and wrhen nearly cold add the two pints and four fluidounces of Alcoholic Tincture first obtained and set aside, and make eighteen pints of Syrup. It may also be flavored with some agreeable aromatic essence, as Sassafras, Wintergreen, Prickly Ash Berries, etc. Properties and Uses.—This is a valuable alterative syrup, and is used with much success in syphilis, scrofula, liver affections, and rheumatism. The iodide of potassium may be added to it, in the same manner as usually pursued with the Compound Syrup of Stillingia, to which this is by no means, second. The dose is a fluidrachm, three or four times a day, in half a gill of water.—J. K. Some twenty years since, a half-breed Indian, called Ben Smith, in the State of New York, made a syrup, which gained considerable reputation as a remedy in syphilitic diseases, and which sold rapidly for three dollars per bottle; the following is the formula for its preparation: Take of Indian Hemp, (Apocyn. Cann.), Virginia Sarsaparilla, Inner Bark of White Pine, each, one pound; Mezereon four ounces; Sheep Laurel half a pound; Water four gallons; Sugar eight pounds. Place the Plants in the water, boil for a few minutes, and then gradually eva- porate, until about tAvo gallons of decoction are left, then strain, and add the Sugar. To each quart bottle of this Syrup he added forty drops of Nitric Acid, and twenty grains of Tartar Emetic dissolved in a sufficient quantity of Spirits. The dose was a wineglassful three times a day. I have never been able to ascertain the true botanical character of the Virginia Sarsaparilla. This syrup has been found as efficacious in syphilis, when prepared without the tartar-emetic. Syrupus Ipecacuanha. Syrup of Ipecacuanha. Preparation. — Take of Ipecacuanha, in poAvder, eight ounces Troy; Alcohol, sp. gr. 0.835, Syrup, of each, a sufficient quantity. Add the Ipecacuanha to twelve fiuidounces of the Alcohol, and allow it to stand for twelve hours; then add sufficient Alcohol to make the mixture of the consistence of Syrup, and introduce the whole into a suitable displacer, in Avhich it gradually settles down as the Alcohol percolates; a piece of 1232 Pharmacy. muslin is laid on the surface, and when it has settled down uniformly, more Alcohol is added until the filtered liquid measures half a gallon, reserving the first half pint that comes through ; distil and evaporate the remainder to eight fluidounces, and then add the reserved half pint. This forms a Fluid Extract of Ipecacuanha, of which two fluidounces represent one ounce Troy, of the root. To four pints of Syrup add eight fluidounces of the above Fluid Ex- tract of Ipecacuanha, and evaporate the Mixture to three pints ; then add four pints of Syrup, and one pint of Water, making one gallon of Syrup of Ipecacuanha. History.—Owing to the presence probably of gum and coloring matter, the Syrup of Ipecacuanha, as generally prepared by diluted alcohol, is very liable to fermentation ; but made according to the above formula of Mr. Joseph Laidley, it contains but little, if any alcohol, possesses all the medicinal virtues of the drug, and keeps as well as simple syrup, without fermenting. When the four pints of syrup are added to the fluid extract, should it not be perfectly clear, it may be rendered so by mixing with water the white of one egg, adding it to the syrup, boiling for a few minutes and straining. Properties and Uses.—This syrup is emetic and expectorant; it is used principally in cases of children. As an emetic the dose for an adult is one or two fluidounces; for a child one or two years old, one or tAvo fluidrachms — to be repeated every fifteen or twenty minutes till it ope- rates. When used as an expectorant, an adult may take one or two fluidrachms ; a child, from five to twenty minims. Mr. A. G. Dunn prepares a "Saccharaled Alcoholic Extract of Ipecac- uanha," which he considers superior to any other preparation of the drug; it is made as follows : Bruise the Root of Ipecacuanha four ounces, to a coarse powder, and macerate for thirty days in Diluted Alcohol sixteen fiuidounces, shaking it occasionally; then filter and express. The tincture thus formed is to be evaporated to two fluidounces, and then mixed with Refined Sugar, eight ounces ; lastly, triturate in a stone mortar until it is entirely dry. This preparation has the peculiar odor and taste of Ipe- cacuanha, is of a brownish-yellow color, is soluble in water, alcohol, ether, mucilage of gum Arabic, etc., is of uniform strength, and agree- able to take. The dose is the same as of the powdered root. Syrupus Lobelia. Syrup of Lobelia. Preparation. — Take of Vinegar of Lobelia two pints; Sugar four pounds. Dissolve with the aid of heat, not to exceed 180°, and continue the heat for three hours, removing any scum which may form, and strain while hot. Properties and Uses.—This forms a pleasant expectorant syrup, and notwithstanding the volatile properties of lobelia are dissipated by heat, this syrup will be found sufficiently active for practical purposes; the Syrupi. 1233 long-continued digestion removes the peculiar, disagreeable taste of the lobelia. It will be found very useful in infantile cases of catarrh, per- tussis, croup, pectoral diseases, to produce emesis, and to brino- the system under the relaxing influence of lobelia. The dose is from one fluidrachm to half a fluidounce.—N T. Isgrigg. Syrupus Mitchella Compositus. Compound Syrup of Partridge- Berry. Mothers' Cordial. Preparation.—Take of Partridge-Berry one pound; Helonias Root, High Cranberry Bark, Blue Cohosh Root, of each, four ounces. Grind, and mix the articles together ; place the whole pound and three quar- ters in a convenient vessel, cover them with fourth proof Brandy, and macerate for three days. Then transfer the whole to a displacement apparatus, and gradually add Brandy, until three pints of spirituous tincture have been obtained, which reserve. Then continue the dis- placement with Hot Water until the liquid passes tasteless, add to this two pounds of Refined Sugar, and evaporate by a gentle heat to five pints ; remove from the fire, add the reserved three pints of Spirituous Tincture, and flavor with Essence of Sassafras. Strictly speaking, this is not a Syrup, but a sweetened Infusion, yet I place it here, as being nearly in its appropriate class. Properties and Uses. — This preparation is a uterine tonic and anti- spasmodic. It may be used in all cases where the functions of the internal reproductive organs are deranged, as in amenorrhea, dysmen- orrhea, menorrhagia, leucorrhea, and to overcome the tendency to habitual abortion. The dose is from two to four fluidounces, three times a day. Pregnant females, especially those of a delicate, or nervous system, will find it an advantage to take one or two doses daily, for several weeks previous to parturition, as by the energy it imparts to the uterine nervous system, the labor will be very much facilitated, beside which, it frequently removes the cramps to which some females are liable during the latter weeks of utero-gestation. The medicine appears to exert a specific influence on the uterus.—J. K. A preparation called the "Parturient Balm," has also been used and recommended in the above diseases, but I have found it to be of less efficacy; however, as some practitioners employ it, I introduce the for- mula for its preparation at this place : Take of Blue Cohosh Root, Spikenard Root, each, four pounds; Black Cohosh Root, Partridge- Berry Herb, Queen of the Meadow Root, of each, two pounds ; Ladies Slipper Root, Comfrey Root, of each, one pound. Proceed to make a Syrup, similar to the directions given for the Compound Syrup of Sar- saparilla, reserving eight pints of the strongest tincture first obtained, using sixty-four pounds of Refined Sugar, and making eight gallons of Syrup. The dose of this is from a teaspoonful to a tablespoonful three or four times a day. 78 1234 Pharmacy. Syrupus Phytolacca Compositus. Compound Syrup of Poke. Preparation.—Take of Poke Root, and Bark of American Ivy, (Am- pelopsis Quinq.), each coarsely bruised, one pound; Black Cohosh Root coarsely bruised, and Sheep Laurel Leaves, each, half a pound. 1. Mix the articles together ; place the whole three pounds in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for three days. Then transfer the whole to a displacement apparatus, and gradu- ally add Hot Water, until one pint and a half of the Alcoholic tincture passes, which retain and set aside. 2. Then continue the percolation, and of this second solution reserve so much as contains a sensible amount of Spirit, and distil or evaporate the Alcohol from it. 3. Continue the displacement by Hot Water, until the solution obtained is almost tasteless, and boil down this weaker infusion until, when added to the second solution after the evaporation of its Alcohol, it will make nine pints. 4. To these two solutions combined, add twelve pounds of Refined Sugar, and dissolve it by heat, carefully removing any scum which arises as it comes to the point of boiling, and if it exceeds ten pints and a half, evaporate to that quantity with constant stirring. Then remove from the fire, and when nearly cold, add the pint and a half of Alcoholic tincture first obtained and set aside, and make one gallon and a half of Syrup. Flavor with some aromatic essence, as Sassafras, Winter- green, etc. Properties and Uses.—This syrup is an excellent alterative and anti- syphilitic, and is beneficial in syphilis, scrofula, and rheumatism. If required, Iodide of Potassium may be added to it, as in the instance of Compound Syrup of Stillingia. The dose is a teaspoonful three or four times a day, in half a gill of water.—J. K Syrupus Pruni Virginiana. Syrup of Wild Cherry Bark. Preparation.— Take of Wild Cherry Bark, in coarse powder, five ounces ; Refined Sugar two pounds ; Water a sufficient quantity. Moisten the Bark thoroughly with Water, let it stand for twenty-four hours in a close vessel, then transfer it to a percolator, and pour Water gradually upon it until a pint of filtered liquor is obtained. Add to this the Sugar, in a bottle, and agitate occasionally until it is dissolved.— U. S. Properties and Uses. — This forms a handsome tonic and sedative syrup, which may be used in all cases where wild cherry bark is indi- cated or desired. It may be given in doses of half a fluidounce. Syrupus Rhei et Potassa Compositus. Compound Syrup of Rhubarb and Potassa. Neutralizing Cordial. Preparation. — Take of best India Rhubarb, in coarse powder, and Bicarbonate of Potassa, each, one pound; Cinnamon, Golden Seal, of each, half a pound; Refined Sugar six pounds ; Fourth Proof Brandy two gallons ; Oil of Peppermint two fluidrachms. Macerate the Rhu- Syrupi. 1235 barb, Potassa, Cinnamon, and Golden Seal, in the Brandy for two days, then express the tincture with strong pressure, and add to it the Oil of Peppermint, previously dissolved in a little Alcohol. Break up the cake or compressed residue from the press, and place it in a displacement apparatus, and gradually add Warm Water, until the strength of the articles is exhausted. Evaporate this solution to eight pints, and while the liquor is still hot dissolve in it the Sugar. Continue the evaporation, if necessary, until when added to the tincture first obtained, it will make three gallons, and mix the two solutions together. Strictly Speaking, this is not a Syrup, but a sweetened Tincture.— W. S. M Dr. Hill has kindly furnished me with the formula by which he pre- pares this syrup, and which many physicians prefer on account of its pleasantness and efficacy. It is as follows: Take of best India Rhubarb, in coarse powder, and pure Carbonate of Potassa, each, two ounces; Golden Seal, Cinnamon, of each, one ounce ; Refined Sugar four pounds; Brandy one gallon; Oil of Peppermint twenty minims. Macerate the Rhubarb, Golden Seal, and Cinnamon, in half a gallon of the Brandy for six hours, with a gentle heat; then transfer the mass to a percolator and displace with the remaining half gallon of Brandy. The remaining strength, if there be any, can be obtained by adding Water until the liquor comes off tasteless. To this add the Carbonate of Potassa, Sugar, and Oil of Peppermint, this last having been previously rubbed with a sufficient quantity of the Sugar to absorb it and mix the two liquors. The whole of the active properties of the ingredients may be obtained with more certainty by using Alcohol 76 per cent., instead of Brandy, owing to the great want of uniformity in the quality of the latter. Properties and Uses.—This syrup is an agreeable laxative, antacid, and tonic. Tt may be used in cases of obstinate constipation, acidity of stomach, dyspepsia, and as a laxative in pregnancy and where piles are present. It is the principal remedy employed by Eclectics in diarrhea, dysentery, cholera-morbus, cholera-infantum, and in the same diseases as the Compound Powder of Rhubarb. The dose for an adult is a table- spoonful, every half hour, hour, or two hours, according to the urgency of the symptoms; for a child in proportion to its age. Syrupus Rumecis Compositus. Compound Syrup of Yellow Dock. Scrofulous Syrup. Preparation.—-Take of Yellow Dock Root two pounds; Bark of the Root of False Bittersweet one pound; Bark of American Ivy, (Ampe- lopsis Quinq.), and Figwort, (Scroph. Mariland.), of each, half a pound; Refined Sugar sixteen pounds. 1. Grind and mix the drugs together, place the whole four pounds in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for two days. Then transfer the whole to a common displacement apparatus, and gradually add Hot Water, until two pints have been obtained, which retain and set aside. 1236 Pharmacy. 2. Then continue the percolation, and of the second solution reserve so much as contains a sensible amount of Spirit, and distil or evaporate the Alcohol from it. 3. Continue the displacement, by Hot Water, until the solution obtained is almost tasteless, and boil down this weaker infu- sion till it begins to thicken, or until, when added to the balance remain- ing of the second portion, after the evaporation of the Alcohol, it will make twelve pints. 4. To these two solutions combined, add the Sugar, and dissolve by heat, carefully removing the scum which arises as it comes to the point of boiling. Then if it exceeds fourteen pints, evapo- rate to that quantity with constant stirring; remove from the fire, and when nearly cold, add the two pints of Alcoholic tincture first obtained and set aside, and make two gallons of syrup. Each pint will contain the virtues of four ounces of the ingredients. It may be flavored with some aromatic essence. Properties and Uses.—This syrup is alterative and antiscrofulous, and is extensively and successfully used in the treatment of scrofula, all scrofulous affections, and many cutaneous diseases. Iodide of potassium is frequently added to it, in the proportion of an ounce to the pint of syrup. The dose is from one to four fluidrachms, three times a day, in about a gill of water; or when the iodide is added, one or two fluidrachms, in water. Syrupus Sanguinaria. Syrup of Bloodroot. Preparation. — Take of Bloodroot, in coarse powder, eight ounces; Acetic Acid four fiuidounces; Water five pints; Refined Sugar two pounds, Troy. Macerate the Bloodroot for three days, in two fluidounces of the Acetic Acid, and a pint of the Water; then transfer to a perco- lator, and displace with the remainder of the Acetic Acid mixed with the balance of the Water. Evaporate by means of a water-bath, to eighteen fluidounces, add the Sugar, and form a syrup. History.—By the above process carefully conducted, the root will be exhausted, and a syrup of a deep ruby color obtained, opake in quantity, but transparent in thin strata, having a strongly acrid and bitterish taste. Properties and Uses.—This syrup may be used in all cases where Bloodroot is applicable, in doses of from ten to sixty drops. An excel- lent cough mixture is composed of equal parts of Syrup of Squill, Syrup of Balsam of Tolu, Syrup of Ipecacuanha, Syrup of Bloodroot, and Paregoric; the dose of which is a teaspoonful whenever the cough is troublesome. Syrups of Wild Cherry Bark, Bloodroot, Balsam of Tolu, and Fluid Extract of Stillingia, combined in equal proportions, have been found very useful in chronic bronchial and catarrhal affections. Syrupus Sarsaparilla Compositus. Compound Syrup of Sarsapa- rilla. Alterative Syrup. Preparation.—Take of the Hoots of Honduras Sarsaparilla, Yellow Dock, Burdock, and ground Guaiacum Wood, each, ten ounces ; Bark of Syrupi. 1237 the Root of Sassafras, of Southern Prickly Ash, Elder Flowers, Blue Flag Root, of each, eight ounces. 1. Grind and mix the articles together, place the whole four pounds and a half in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for two days. Then transfer the whole to a common displacement apparatus or percolator, and gradually add Hot Water, until two pints have been obtained, which retain and set aside. 2. Then continue the percolation, and of the second solution reserve so much as contains a sensible amount of Spirit and distil or evaporate the alcohol from it. 3. Continue the displacement, by Hot Water, until the solution obtained is almost tasteless, and boil down this weaker infusion till it begins to thicken, or until, Avhen added to the balance remaining of the second portion, after the evaporation of the alcohol, it will make twelve pints. 4. To these two solutions combined, add sixteen pounds of Refined Sugar, and, by heat, dissolve—carefully removing the scum which arises as it comes to the point of boiling. Then, if it exceeds that quantity, evaporate the Syrup with constant stirring, to fourteen pints, remove from the fire, and when nearly cold, add the two pints of tincture first obtained, and make two gallons of Syrup. Each pint will contain the virtues of four ounces of the ingredients. It may be flavored with essence of Wintergreen, Sassafras, or Prickly-Ash Berries, etc. Properties and Uses.—This forms a valuable Syrup, which may be used in all cases where an alterative is indicated; in chronic hepatitis, rheumatism, syphilis, scrofula, cutaneous diseases, ulcers, white swell- ing, rickets, necrosis, and every taint of the system. Some physicians add an ounce of the Iodide of Potassium to every pint of Syrup. The dose is from a teaspoonful to a tablespoonful, three or four times a day, in about a gill of water. Syrupus Scilla. Syrup of Squill. Preparation.—Take of Vinegar of Squill a pint; Refined Sugar two pounds. Add the Sugar to the Vinegar of Squill, dissolve with the aid of heat, removing any scum which may form, and strain the solution while hot.— U S. Properties and Uses.—Syrup of Squill is used as an expectorant in coughs and catarrhs, and as an emetic in infantile cases of catarrh, and other pectoral complaints. It is frequently given in combination with Tincture of Lobelia, and other emetic or expectorant agents. The dose of it is about a fluidrachm. Syrupus Senega. Syrup of Seneka. Preparation.—Take of Seneka, in coarse powder, four ounces; Alco- hol half a pint; Water a pint and a half; Refined Sugar fifteen ounces. Mix the Alcohol and Water, pour half a pint of the liquid on the Seneka, and allow the mixture to stand for twelve hours; then transfer it to a percolator, and gradually pour upon it the remainder of the menstruum, When the liquor has ceased to pass, evaporate it by means of a water- 1238 Pharmacy. bath to half a pint, filter, and, having added the Sugar, dissolve Avith the aid of heat, removing any scum which may form, and strain the solu- tion while hot.— U. S. A still better plan for preparing this Syrup, is according to that laid down for Syrup of Ipecacuanha, by first preparing an Alcoholic Fluid Extract, and adding it to Simple Syrup; by this method the separation of the gum and other matters which cause a tendency to fermentation, is entirely avoided. Properties and Uses.—This forms a stimulating expectorant, which is often very useful in pectoral complaints. It is frequently combined with syrup of squill, tincture of lobelia, syrup of sanguinaria, etc. Its dose is one or two fluidrachms. Syrupus Stillingia. Syrup of Queen's Root. Preparation.—Take of Queen's Root three pounds ; Prickly Ash Ber- ries one pound and a half; Refined Sugar eighteen pounds. 1. Grind, and mix the articles together; place the whole four pounds and a half in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for three days. Then transfer the whole to a displacement apparatus, and gradually add Alcohol, until five pints of the Alcoholic tincture have been obtained, which retain and set aside. 2. Then con- tinue the percolation with Hot Water, until the liquor passes almost tasteless, add the Sugar to it, and evaporate by gentle heat until thirteen pints are obtained; to which add the reserved five pints of Alcoholic tincture, and make eighteen pints of Syrup. It may be flavored with Essence of Sassafras, if required. Properties and Uses.—This has been found highly beneficial in bron- chial and laryngeal affections, also in obstinate cases of rheumatism, and wherever a stimulating alterative is required. The dose is from a fluidrachm to half a fluidounce, three, four, or five times a day, accord- ing to the urgency of the symptoms. It should be taken in water. Syrupus Stillingia Compositus. Compound Syrup of Queen's Root. Preparation.—Take of Queen's Root, and Root of Turkey-Corn, each, two pounds ; Blue Flag-root, Elder Flowers, and Pipsissewa Leaves, of each, one pound; Coriander, and Prickly Ash Berries, of each, half a pound. 1. Grind, and mix the articles together; place the whole eight pounds in a convenient vessel, cover them with Alcohol of 76 per cent., and macerate for three days. Then transfer the whole to a displacement apparatus, and gradually add Hot Water until four pints of the Alcoholic tincture have been obtained, which retain and set aside. 2. Then con- tinue the percolation, and of this second solution reserve so much as contains a sensible amount of Spirit, and distil or evaporate the Alcohol from it. 3. Continue the displacement by Hot Water, until the solution obtained is almost tasteless, and boil down this weaker infusion until, when added to the second solution after the evaporation of its Alcohol, Syrupi. 1239 it will make twenty-four pints. 4. To these two solutions combined, add thirty-two pounds of Refined Suga*f, and dissolve it by heat, carefully removing any scum which arises as it comes to. the point of boilino-; and if it exceeds twenty-eight pints, evaporate to that quantity, with constant stirring. Then remove from the fire, and whenxpearly cold add the four pints of reserved Alcoholic tincture and make four gallons of Syrup, each pint of which will be equal to four ounces of the ingredients in medicinal virtue. Properties and Uses.—This is a most powerful and effective alterative, and is extensively used by Eclectic practitioners in all syphilitic, scrofu- lous, osseous, mercurial, hepatic, and glandular diseases ; or in every case where an alterative is indicated. It is most commonly given with an ounce of Iodide of Potassium added to each pint of the syrup. The dose is a fluidrachm, three or four times a day, in half a gill of water; but where the Iodide is omitted, the dose is from a fluidrachm to a fluidounce, three or four times a day, also in water. This is considered one of the most potent Eclectic remedies in all chronic diseases. Syrupus Tolutanus. Syrup of Tolu. Preparation. — Take of Tincture of Tolu a fluidounce and a half; Refined Sugar two and a half pounds, Troy ; Water a pint. Mix the Tincture with one pound of Sugar in a shallow dish, and evaporate the Alcohol with the aid of a gentle heat, or allow it to evaporate sponta- neously ; then add the remainder of the Sugar, and dissolve it in twelve ounces of the Water. With the remaining four ounces of Water, beat up the white of one Egg, add it to the Syrup, boil for one or two minutes, and strain through a Canton flannel bag. Properties and Uses.—This syrup is used in coughs, and to impart an agreeable flavor to mixtures; the dose is from half a fluidrachm, to two, or even four fluidrachms. Syrupus Zingiberis. Syrup of Ginger. Preparation.—Take of Tincture of the best Jamaica Ginger two fluid- ounces; Refined Sugar five pounds; Water two pints. Mix the Tincture with two pounds of Sugar in a shallow dish, and evaporate the Alcohol with the aid of a gentle heat, or allow it to evaporate spontaneously; then add the remainder of the Sugar, and dissolve it in tAventy-four ounces of the Water. With the remaining eight ounces of the Water, beat up the whites of two Eggs, add it to the Syrup, boil for one or two minutes, and strain through a Canton flannel bag. Properties and Uses.—Syrup of Ginger is used as a warm stomachic addition to purgative, tonic, or other infusions or mixtures, and to im- part flavor to drinks. The dose is from half a fluidrachm, to two, three, or four fluidrachms. 1240 Pharmacy. TINCTURE. Tinctures. Tinctures are officinal preparations, obtained either by the solution, maceration, digestion, or percolation of the principles of certain sub- stances in Alcohol, or by the simple mixture of Alcohol with an Acid or Alkaline liquid. They are Simple tinctures when they contain the active principles of a single substance, and Compound tinctures, when they con- tain those of several. Occasionally, Spirit of Ammonia or Ether are em- ployed as the solvents, furnishing Ammoniated tinctures, and Ethereal tinctures. Tinctures are also prepared by means of gin, brandy, wine, etc., as the solvent; the former are termed Spirituous Tinctures, and those with wine, Vinous Tinctures, or Medicated Wines. When the prin- ciple to be dissolved is insoluble in water, rectified spirit, (alcohol of sp. gr. 0.835,) is preferred as the menstruum; when it is soluble in both alcohol and Avater, diluted or proof spirit is preferred. The former is applicable to resins, guaiacum, camphor, and the essential oils, in which the presence of Avater would interfere with the solvent power of the alcohol; the latter is proper where the articles contain extractive, tan- nin, gum united with resin, or essential oil. In preparing Tinctures, as a general rule, the medicine should be in the dry state, and very finely pulverized ; it should first be moistened Avith the liquid, after Avhich the whole quantity may be added. There are, however, some exceptions to this rule, as for instance, where the powder, by agglutination, presents an obstacle to the action of them en- struum : in this case, the substance to be acted upon should be coarsely bruised, sliced, or pulverized. It is recommended that, when several substances of various solubilities are employed, they be added succes- sively to the spirit; those least soluble first, those most so last; as other- wise the liquid might become saturated with the ingredient for which it has the strongest affinity, and thus be rendered incapable of dissolving a due proportion of the others. Tinctures prepared by maceration or digestion require to be kept in well-stopped vessels in order to prevent the evaporation of alcohol; to be frequently shaken during the maceration or digestion, which should be continued, at ordinary temperatures, for a period of two weeks: if prepared by digestion a shorter time is required. They may then be expressed, if required, and filtered, though some are in the habit of allowing the dregs to remain, on the supposition that it contributes to maintain the uniformity of strength, and prevent any precipitation that might otherwise ensue ; but this is an error. The preparation of tinctures by percolation or displacement, answers very well for small operations, but is scarcely adapted in cases where any large quantity of tincture is required, and is not so excellent a mode for general purposes as that of maceration, unless skillfully executed by persons experienced in the proper method of conducting it. Tinctura. 1241 It has, likewise, been recommended to suspend in the solvent, imme- diately under its surface, the solid matter in powder or bruised, and contained loosely in a bag, raising it occasionally above the surface of the liquor, allowing it to drain, and again immersing it. It is said that the period of maceration is much shortened in this way. As the upper portion of liquid becomes heavier by impregnation with the substances dissolved, it falls to the bottom, and a constant current is thus estab- lished, which continues until the liquid is saturated, or the solid substance exhausted. Preserved vegetable juices, or the tinctures of the expressed juices of various plants, are prepared by adding alcohol of 0.838 one part, to four parts of the juice, after this last has stood for twenty-four hours, and then filtering another period of twenty-four hours after the addition of the alcohol. This preserves the juice, and at the same time precipitates the inert mucilaginous matter. Tinctures should always be kept in accurately stopped bottles, as, otherwise, the evaporation of the alcohol, by increasing their strength, might be attended with serious consequences. I am indebted to Mr. Wm. S. Merrell, of this city, an experienced and practical pharmaceutist, who has kindly furnished me with the fol- lowing observations on this subject: "A Tincture, in the pharmaceutical sense, is the solution of some medicinal substance in Alcohol, either pure or diluted, and is mostly employed to separate the more active Medicinal principles of vegetables from their woody fiber and other nearly inert substances, as starch, gum, and mucilage, which are not soluble in that menstruum, and present them in a liquid form. The greater part of the more active proximate princi- ples of vegetables are soluble in strong Alcohol, but many of them, espe- cially in their native combinations, are also soluble in Water, and a few, of an extractive or saline character, are more soluble in the latter than in the former menstruum. And in most cases an admixture of Water facilitates the process of tincturing, by softening the mucilage and other principles not soluble in Alcohol, thus enabling the latter to penetrate the substance, and act more readily. In these cases, therefore, a dilute spirit, or mixture of alcohol and water, should be used ; and the proper proportions of such mixture for tincturing the different articles of the Materia Medica, becomes an important lesson to be learned by the apoth- ecary and the physician. In the tinctures recognized as officinal, in the U. S. Dispensatory, the streno-th of the solvent is, in most cases, indicated with sufficient accu- racy, but in the progress of reform, a great number of medicines have been brought into use, in respect to which we have hitherto had no such guide. Some general suggestions may, therefore, be useful to the less experienced practitioner. 1242 Pharmacy. In all cases it is proper to use as dilute a spirit as is adequate to obtain the strongest practical tincture, provided it be sufficiently strong to pre- vent fermentation, and preserve the solution from decomposition and change; for the alcoholic stimulant, in itself considered, is in most cases undesirable. The common alcohol of commerce, marked 76 per cent., is sufficiently strong for almost any of these preparations. It is strong enough to dissolve the resins, such as guaiacum, tolu, etc., and also the essential oils, in the proportions directed, and this is all that is required. The dilute alcohol of the Dispensatory, is nearly represented by a mixture of the tAvo parts common alcohol, of 76 per cent., and one part water, which is about the right strength for the majority of the vegetable tinctures. Those roots, however, of which the medicinal virtues consists mostly of a resinoid, as podophyllum, leptandra, and many others, and also those vegetables containing much essential oil, require a solvent somewhat stronger than this, and either the 76 per cent, alcohol, or that reduced but little below this standard, say to the strength of fourth proof SDirits, should be used. On the other hand, medicines which are almost wholly of an extractive character, as aloes, and others whose medicinal principles are soluble in water, require very dilute alcohol to tincture them, (see Art. Aloes, in U. S. Disp.,) as the only use of the spirit in this case is to precipitate and render insoluble the mucilage, and to prevent the tincture from spoiling. Gum Kino should be tinctured in dilute alcohol, and not in strong, as directed in the Pharmacopoeias; for if prepared in alcohol of officinal strength, it will rapidly gelatinize on standing, which will not be the case if prepared with spirit somewhat diluted, and kept in well closed vessels. In the preparation of tinctures from such vegetables as require dilute spirit, the process may be much facilitated, if not rendered more perfect, by first wetting the ground or powdered substance Avith the proportion of water that is admissible, say one-third. Apply the water hot, and after digesting a short time, sufficient to expand the ligneous fiber, and soften or dissolve the gum, mucilage, etc., add the required proportion of Alcohol, which can thus readily reach and dissolve the active princi- ples soluble in it, while at the same time, it precipitates the dissolved mucilage, etc. For example: Tinctura Cimicifuga. Tincture of Black Cohosh. R- Black Cohosh Root,...................four ounces. Boiling Water,.......................eight fiuidounces. Alcohol, 76 per cent...................one pint and a half. Powder or bruise the root, and pour the boiling water upon it, and let it digest for two hours; then, Avhen sufficiently cool, transfer it to the bottle in which it is to be kept, and add the alcohol. Let it stand three days, frequently shaken, and filter for use. Tinctura. 1243 [I differ somewhat with Mr. Merrell's method of preparing this tinc- ture. As the virtue exists principally in the resin and oil, there is no necessity for the addition of any Water to the preparation, and I have obtained much better results from the tincture, Avith strong alcohol, as I always prepare it, than from the diluted tincture.—A".] Acting upon this principle, I many years ago made what I consider an improvement in the mode of preparing the tincture of opium, which should be adopted by every physician and apothecary. The directions in the old Pharmacopoeias are, to slice the opium, and put it in the bottle with dilute alcohol, and macerate Avith frequent shaking, for two Aveeks ; but if the opium be hard and compact, many small lumps will not be dissolved for a long time. I have examined the dregs of laudanum after standing six months under the tincture, and haAre found in them still unpenetrated pieces of pure opium. The consequence of such a mode of preparation is, that the tincture will at first be quite weak, and will continue to increase in strength until near the last, when it will be far above the standard strength, and liable to produce dangerous conse- quences. To avoid this objection, the later editions of the U. S. Phar- macopoeias direct that the opium be first dried and powdered ; but this adds one-fourth to the expense, if the opium be purchased ready pow- dered, and takes time, trouble and labor, which the physician cannot often spare, to dry and powder it himself, and hence it is seldom done. The whole difficulty may be avoided by the following method : Take of good Turkey Opium, 1200 grains, (about 2| ounces avoirdupois. This is the proportion required by the U. S. and most of the European Dis- pensatories, although most of the laudanum sold in the shops is only the strength of one ounce avoirdupois to the pint). Slice the opium and pour over it half a pint (3 viii.) boiling water, and work it with the pestle or hand until it is dissolved into a perfect emulsion, and no lumps can be felt in it, which is done in a very few minutes; then pour it into the bottle, and with two ounces more of warm water rinse your vessels, pestle, and hands, and add this to the above, and then add twenty fluid- ounces of common alcohol, 76 per cent.—Shake it well. In this manner a quart, or any other quantity of laudanum can be made in half an hour, and in twenty-four hours it will be of full and uniform strength. In making each subsequent batch, the dregs of the former one should be poured out upon a paper filter in a funnel, and the alcohol for the new batch be percolated through it, thus preserving all the strength of this costly drug. I find that the Edinburgh College have in the latter edi- tions of their Dispensatory, adopted a plan somewhat similar to the above, but much more troublesome and wasteful. In the same manner we may advantageously make the tinctures of the gum-resins, as Myrrh, Assafetida, etc.; but in these cases a smaller proportion of water must be employed, unless it be counterbalanced by 1244 Pharmacy. using the strong officinal alcohol, as the proper solvent for these gums is a stronger spirit than that required for opium."

Tincture of Acetate of Iron. Preparation. — Take of Sulphate of Iron eight ounces, avoirdupois; Distilled Water half a pint, (ten fluidounces, Imperial measure); Pure 1254 Pharmacy. Sulphuric Acid six fiuidrachms, (Imp. meas.); Pure Nitric Acid half a fluidounce, (Imp. meas.) ; Acetate of Potassa eight ounces, (avoird.) ; Rectified Spirit half a gallon, (Imp. meas.). To nine fluidounces of the Water add the Sulphuric Acid, and in the mixture, with the aid of heat, dissolve the Sulphate of Iron. Add next the Nitric Acid, first diluted writh the remaining fluidounce of Water, and evaporate the resulting solution to the consistence of a thick syrup. Dissolve this in one quart (two pints, Imp. meas.), and the Acetate of Potassa in the remainder of the Spirit, and, having mixed the solutions, and shaken the mixture repeatedly in a large bottle, let the whole be thrown upon a calico filter. When any further liquid ceases to trickle through, subject the filter, with its contents, to expression, and having cleared the turbid tincture thus procured by filtration through paper, let it be added to that already obtained. The specific gravity of this tincture is 0.891.—Dub. History.—In the first part of this process the sulphate of protoxide of iron is converted, by the action of the sulphuric and nitric acids, aided by heat, into the tersulphate of the sesquioxide. This is dissolved in half the spirit, and the acetate of potassa in the remaining half, and the two spirituous solutions being mixed, a double decomposition ensues; sulphate of potassa, which is insoluble in rectified spirit, is precipitated, while the teracetate of sesquioxide of iron remains in solution. This, when filtered, constitutes the present tincture of acetate of iron. The whole of the acetate of potassa is decomposed, in consequence of sul- phate of iron being added in excess; and the filtration removes not only the sulphate of potassa, but also the excess of the iron salt, which is insoluble in alcohol. Properties and Uses.—This is a deep-red, transparent liquid, having a strong chalybeate taste. It is tonic and astringent, and beside its internal administration as a chalybeate, it forms an excellent vaginal enema for leucorrhea, when properly diluted with water. The dose of it is from twenty drops to a teaspoonful, given in a sufficient quantity of water. Tinctura Ferri Chloridi. Tincture of Chloride of Iron. Tincture of Muriate of Iron. Preparation.—Take of Subcarbonate of Iron half a pound; Muriatic Acid, sp. gr. 1.16, a pint; Alcohol three pints. Pour the Acid upon the Subcarbonate of Iron, in a glass or porcelain vessel, mix them, and when effervescence has ceased, apply a gentle heat, and continue it, stirring occasionally, until the carbonate is dissolved; then filter the solution, and mix it with the Alcohol.— U. S. History.—Tincture of Chloride of Iron is a liquid of a reddish-brown, somewhat yellowish color, a sour and exceedingly styptic taste, and an odor somewhat like that of muriatic ether; On exposure to the air, a small deposit of sesquioxide of Iron may take place, rendering the Tinctura. 1255 tincture proportionably feeble, but this can be easily obviated by adding sufficient muriatic acid to dissolve the precipitate. It is incompatible with the alkalies, alkaline earths and their carbonates, astringent vegetable infusions, and the mucilage of gum arabic. When the tincture is eva- porated, the resulting sesquichloride of iron is of a dark orange color, hardly crystallizable, deliquescent, and composed of two equivalents of iron 56, and three of chlorine 106.26=162.26. Properties and Uses.—This chalybeate Tincture is tonic, diuretic and astringent. It is very useful in scrofula, gleet, chronic gonorrhea, leu- corrhea, dysury dependent on spasmodic stricture, and passive hemor- rhage from the uterus, kidneys or bladder. The dose is from ten to thirty drops, two or three times a day, diluted with a sufficient quantity of water. In doses of from ten to twenty drops, in water, and repeated every two hours, the Tincture of Chloride of Iron has been found a valuable agent in the treatment of erysipelas, usually effecting a cure in from two to six days, and during the employment of which, the only local applications necessary are hair powder, and cotton wadding. The bowels to be kept open. Externally, it has proved useful in destroying venereal warts, as a styptic in cancerous and fungous ulcers, and is one of the best applications that can be applied to a venereal chancre. In this last, it should be applied by means of a feather; and a piece of lint moistened with it, should be kept in constant contact with the sur- face of the ulcer. As an application to chancre, it is the only one that I have made for the last fifteen years, (except the nitric acid during its pustular stage,) and is, in my opinion, decidedly the best local remedy for this kind of ulcer that can be used. Occasionally it causes severe pain, when it should be diluted with as little water as possible, but in the majority of instances after the first or second application, patients hardly notice it. It keeps the chancre clean, its surface soft, and changes the poisonous character of the virus, so that its absorption is followed by no bad result. As the chancre soon becomes so changed, by the uses of this tincture, that it is frequently difficult to detect it from the healthy surrounding integuments, the practitioner must be careful not to be misled by this appearance and cease his internal treatment too soon. Prof. R. S. Newton, to whom I made known this employment of the tinc- ture, and several others, have used it with the most beneficial results. Tinctura Gelsemini. Tincture of Yellow Jessamine. Preparation.—Take of the fresh Root of Yellow Jessamine, cut into small pieces, eight ounces; Alcohol two pints. Macerate for fourteen days, express and filter. This forms a saturated tincture, beautifully tinged with violet; it has a peculiar odor somewhat resembling that of new honey, and a faint, peculiar, not unpleasant taste. Properties and Uses.—This Tincture possesses the active properties of the root, and may be given as a febrifuge in intermittent, remittent, 1256 Pharmacy. typhus, typhoid, and many other fevers ; it is likewise beneficial in neu- ralgia, nervous headache, toothache, etc. And combined with tincture of cimicifuga, or tincture of colchicum, it proves decidedly efficacious in rheumatism and gout. In rigidity of the os uteri, puerperal convulsions, puerperal peritonitis, and painful dysmenorrhea, I consider this the very best agent in the Materia Medica. I have employed it in all these vari- ous conditions and with the most marked success. It is preferable to lobelia as a relaxant, as it does not occasion any nausea or vomiting. To one young lady laboring under a most agonizing dysmenorrhea, I administered a teaspoonful of the tincture every half hour for four hours, before it produced its influence upon her, after which, smaller doses sufficed to maintain its effect, and she suffered no further pain during the menstruation. While it produces a relaxation of the rigid os uteri, it seems to exert an influence on the uterine contractility, pro- moting this action of the organ. However, I have only noticed this latter effect in a few instances; further investigations are required before we can place any reliance on this therapeutical action from its adminis- tration during parturition. The dose of the tincture of gelseminum is from ten drops to a fluidrachm, according to circumstances, and the urgency of the case. The effects of an overdose may be removed, by holding aqua ammonia to the nostrils, with the internal administration of stimulants. Tinctura Gentiana Composita. Compound Tincture of Gentian. Preparation.— Take of Gentian, Colombo, Swamp Milkweed, Rhu- barb, Prickly Ash Berries, Sassafras, each, in powder, one ounce; Good French Brandy four pints. Macerate for fourteen days and filter. This Tincture may also be prepared from the same dry materials, in the state of powder, by moistening them thoroughly with Brandy, allowing them to stand for forty-eight hours, then transferring them to a percolator, and gradually pouring upon them Brandy until four pints of filtered liquor are obtained. Properties and Uses.—This is a mild aperient, stimulant, and tonic, and is especially adapted to children with debilitated stomachs, or dis- ordered condition of the digestive organs, after the administration of anthelmintics for the removal of worms, and during convalescence from exhausting diseases, as summer-complaint, diarrhea, dysentery, fevers, etc. The dose is from ten drops to a teaspoonful three or four times a day, in sweetened Avater.—J. K. Tinctura Guaiaci. Tincture of Guaiacum. Preparation.—Take of Guaiacum, in powder, half a pound; Alcohol two pints. Macerate for fourteen days and filter through paper.— U. S. Properties and Uses.—This Tincture is used in gout, rheumatism, dys- entery, amenorrhea, and dysmenorrhea ; the dose is from one to three Tinctura. 1257 fluidrachms, three or four times a day, given in mucilage, or SAveetened water. Dewees' Tincture of Guaiacum, (Tinctura Guaiaci Alkalina,) recommended in suppression of the menses and dysmenorrhea, is made as follows : Take of the best Guaiac, in poAvder, four ounces; Carbonate of Soda or of Potassa, one drachm and a half; Pimento, in poAvder, an ounce ; Diluted Alcohol a pound. Digest for a few days. Dose, a tea- spoonful three times a day, to be gradually increased, if necessary. Tinctura Guaiaci Aromatica. Aromatic Tincture of Guaiacum. Greenhow's Cholera Mixture. Preparation. — Take of Guaiacum, Cloves, and Cinnamon, each, in powder, one ounce ; Brandy two pints. Macerate for fourteen days and filter. Properties and Uses. — This Tincture is an excellent aromatic stimu- lant, astringent, and diaphoretic. It was extensively used in Cincinnati, by the Eclectics, during the cholera of 1849-50-51, and with excellent effect. The late Prof. T. V. Morrow, considered it as one of the best agents in the treatment of that disease. The dose is from a teaspoonful to a tablespoonful, in sweetened water, every fifteen or twenty minutes, until relief is obtained. The addition of an ounce of Prickly Ash Ber- ries to this tincture will materially enhance its value. Tinctura Hydrastis. Tincture of Golden Seal. Preparation.—Take of Golden Seal Root, in powder, three ounces ; Diluted Alcohol one pint. Macerate for fourteen days, express and filter. This Tincture may also be prepared by thoroughly moistening the Golden Seal Root, in powder, with Diluted Alcohol, allowing it to stand for forty-eight hours, then transferring it to a percolator, and gradually pouring upon it Diluted Alcohol until two pints of filtered liquor are obtained. Properties and Uses.—This Tincture is tonic, and will be found bene- ficial in chronic gastric affections, hepatic diseases, chronic diarrhea, and general debility. Diluted and applied locally, it forms an efficacious remedy in leucorrhea, and ophthalmia. The dose is from ten to sixty drops, two or three times a day, in water. Tinctura Hydrastis Composita. Compound Tincture of Golden Seal. Preparation.—Take of Golden Seal Root, Lobelia Seed, each, in pow- der, two ounces ; Diluted Alcohol one pint. Macerate for fourteen days, express, and filter through paper. This Tincture may also be prepared from the same dry materials, in powder, by moistening them thoroughly with Diluted Alcohol, allowing them to stand for forty-eight hours, then transferring them to a perco- lator, and gradually pouring upon them Diluted Alcohol until one pint 1258 Pharmacy. of filtered liquor is obtained. Or, it may be made by adding together equal parts of the Tinctures of Golden Seal, and Lobelia. Properties and Uses.—This is a valuable local application to diseased mucous surfaces. It is highly recommended by Prof. Z. Freeman, in chronic catarrh, to be snuffed up into-the nostrils, or applied by means of a camel's hair pencil ; it is also useful in chronic ophthalmic diseases, diluted with water.—Z. F. Tinctura Hyoscyami. Tincture of Henbane. Preparation.—Take of Henbane Leaves four ounces; Diluted Alco- hol two pints. Macerate for fourteen days, express, and filter through paper. This Tincture may also be prepared by thoroughly moistenino- the Henbane Leaves, in powder, with Diluted Alcohol, allowing them to stand for twenty-four hours, then transferring them to a percolator, and gradually pouring upon them Diluted Alcohol until two pints of filtered liquor are obtained.— U. S. Properties and Uses.—This Tincture is anodyne and soporific, and may be used as a substitute for Opium in cases where this latter drug disagrees, or where its constipating effects are not desired. Sometimes the Tincture of Henbane purges; when this is the case, a small portion of laudanum may be added to it. The dose is from half a fluidrachm to a fluidrachm. Tinctura Hyperici. Tincture of St. John's Wort. Preparation.—Take of the Blossoms of St. John's Wort (recent) five ounces; Alcohol one pint. Macerate for fourteen days, express, and filter. Properties and Uses.—This Tincture may be used to fulfill the indica- tions of the plant; but its principal use is as a local application to wounds, bruises, ulcers, swellings, tumors, ecchymosis, etc. The dose internally is from half a fluidrachm to a fluidrachm. As a local applica- tion it is equal to Arnica. Tinctura Iodinii. Tincture of Iodine. Preparation.—Take of Iodine an ounce; Alcohol a pint. Dissolve the Iodine in the Alcohol.— U. S. History. — The Tincture of Iodine should be kept in well stopped bottles, and not exposed to the light, and it is better to make up but small quantities at a time, as a reaction takes place between the iodine and alcohol, producing chemical changes, especially if the tincture be exposed to the action of light. In preparing the tincture the iodine should be well dried. It has a deep brown color, becomes gradually decomposed on standing, -or on the addition of water. Properties and Uses. —This preparation is seldom administered inter- nally, on account of its liability to precipitation in the stomach, and Tinctura. 1259 consequent irritation produced by the crude iodine. When given, the dose is ten drops, gradually increased to thirty, tAvo or three times a day, to be administered in sweetened water, or still better, Avine, if not contra- indicated. Thirty drops are about equal to one grain of iodine. Its principal use is externally, in erysipelas, chilblains, and several cutane- ous diseases—it has likewise been recommended as a local application in local rheumatism, croup, bites of serpents, etc. It may be applied by means of a camel's hair pencil. Tinctura Iodinii Composita. Compound Tincture of Iodine. Preparation.—Take of Iodine half an ounce ; Iodide of Potassium an ounce ; Alcohol a pint. Dissolve the Iodine and the Iodide of Potassium in the Alcohol.— U. S. Properties and Uses.—This Tincture may be used internally for all the purposes to which iodine is applicable. Unlike the Tincture of Iodine, it is not decomposed when diluted with water. The dose is five drops, three times a day, gradually increased to thirty if necessary. Tinctura Iridis. Tincture of Blue Flag. Preparation.—Take of Blue Flag Root, in powder, three ounces ; Alco- hol a pint. Macerate for fourteen days, express, and filter. This Tincture may also be prepared by thoroughly moistening the Blue Flag Root, in powder, with Alcohol, allowing them to stand for forty- eight hours, then transferring them to a percolator, and gradually pour- ing upon them Alcohol, until one pint of filtered liquor is obtained. Properties and Uses.—The Tincture of Blue Flag possesses the same alterative and cathartic properties as the root, and may be used in all cases as a substitute for the powder, in doses of from ten to sixty drops, according to the effect desired, two or three times a day. Six fluidrachms, each, of the Tinctures of Blue Flag, and Mandrake roots, with two fluidrachms of a saturated tincture of Nux Vomica, form an efficacious remedy in obstinate constipation, hepatic torpor, derangements of the spleen, sick headache, want of appetite, syphilitic affections, gleet, recent stricture of the urethra, impotency from masturbation, recent disease of the prostate, etc. The mixture may be given in doses of from ten to fifteen drops, in water, two or three times a day.

This Tincture may also be prepared by thoroughly moistening the Sheep Laurel Leaves, in powder, with Diluted Alcohol, allowing it to stand for twenty-four hours, then transferring it to a percolator, and gradually pouring upon it Diluted Alcohol until one pint of filtered liquor is obtained. 1260 Pharmacy. Properties and Uses.—This preparation is sedative and alterative, and may be successfully used in jaundice, syphilitic diseases, palpitation of the heart, etc., in doses of ten drops, carefully and gradually increased to thirty. In obstinate syphilitic affections, I frequently add a portion of this tincture to the Compound Syrup of Stillingia, Avith marked advan- tage. Externally, the tincture is beneficial in itch, and some other cuta- neous affections. Tinctura Kino. Tincture of Kino. Preparation.—Take of Kino, in powder, three ounces and a half; Dis- tilled Water twelve fiuidounces ; Alcohol twenty fiuidounces. Macerate for fourteen days, and filter. This Tincture may also be prepared by mixing with the powdered Kino, an equal bulk of Sand, transferring the mixture to a percolator, and gradually pouring upon it the above proportions of Alcohol and Dis- tilled Water, mixed together, until two pints of filtered liquor are obtained. Properties and Uses.—Tincture of Kino is astringent, and is princi- pally used in diarrhea, cholera morbus, cholera, etc., in doses of one or two fluidrachms ; it is frequently added to astringent mixtures. It is very liable to gelatinize on standing, and lose its astringency, especially if exposed to the action of the atmosphere ; hence, it should be made frequently, in small quantities at a time, and be kept in well stopped bottles. Tinctura Krameria. Tincture of Rhatany, Preparation.—Take of Rhatany, in powder, six ounces; Diluted Alco- hol two pints. Macerate for fourteen days, express, and filter through paper. This Tincture may also be prepared by moistening the Rhatany thoroughly with Diluted Alcohol, allowing it to stand for forty-eight hours, then transferring it to a percolator, and gradually pouring upon it Diluted Alcohol until two pints of filtered liquor are obtained.— U S. Properties and Uses.—This is useful in chronic diarrhea, and other cases where an astringent is required. It likewise forms an excellent local application to the gums, where they are tender, spongy, and bleed. The dose is one or two fluidrachms in sweetened water, or wine, if not contra-indicated, three or four times a day. Tinctura Laricis Composita. Tinctura Pinus Pendula Compo- sita. Compound Tincture of Tamarac. Bone's Bitters. Preparation.—Take of Tamarac Bark, Juniper Berries, of each, six ounces; Prickly Ash Bark four ounces; Wild Cherry Bark, Seneca Snakeroot, of each, three ounces; Tansy one ounce ; Whisky five pints; Molasses a pint and a half; Hydro-alcoholic Extract of Mandrake an ounce and a half; Water a sufficient quantity. Let the medicinal Herbs, Tinctura. 1261 Roots, and Barks, be coarsely pulverized and mixed together. To the mixture add three pints of the Whisky, and let them stand twenty-four hours ; then place the whole in a vapor displacement apparatus, and force through the articles the steam, or vapor of the additional Whisky two pints, after which the steam from Water sufficient to make the whole amount of Tincture equal to twenty-four pints. To this add the Mo- lasses, and the Hydro-alcoholio Extract of Mandrake; which last must be thoroughly dissolved. Properties and Uses.—Although not properly a tincture, yet to avoid a new class of pharmaceutic agents, bitters, I place this compound among the tinctures. It is an improvement upon the original Bone's Bitters, and is now generally preferred by Eclectics. It possesses nearly four times the strength of that heretofore made, and consequently must be taken in a much smaller dose, a desideratum with all medicines contain- ing alcohol. The whisky and juniper berries are less expensive, and more readily obtainable than the pure Holland Gin recommended in the original, and likewise render the preparation more actively diuretic; and the substitution of the Extract of Mandrake, for the bitter, and to many patients, unbearable taste of aloes, renders it much more valuable as a cholagogue, alterative, and aperient. It forms an excellent alterative tonic and aperient for dyspepsia, menstrual obstructions, and other dis- eases where such a combination of action is indicated. The dose is half a fluidounce, three times a day, about an hour previous to each meal. Tinctura Lavandula Composita. Compound S])irit of Lavender.

Macerate for fourteen days, express, and filter through paper. Properties and Uses.—This is far superior to, and makes a much more agreeable compound than the formula of the U. S. Pharmacopoeia. It forms a delightful preparation which is much employed as a remedy for flatulence, hysteria, gastric uneasiness, nausea, and general languor or faintness. It is also used as an adjuvant and corrigent of other medicines. The dose is from thirty drops to a fluidrachm or two, given in sweetened water, or on sugar.—/. K. Tinctura Leptandra. Tincture of Blackroot. Preparation.—Take of Black Root, in powder, three ounces ; Diluted Alcohol one pint. Macerate for fourteen days, express, and filter. This Tincture may also be prepared by thoroughly moistening the Black Root, in powder, with Diluted Alcohol, allowing it to stand for forty-eight hours, then transferring it to a percolator, and gradually pour- ing upon it Diluted Alcohol until one pint of filtered liquor is obtained. 1262 Pharmacy. Properties and Uses.—This preparation is aperient and cholagogue, and is employed in various derangements of the biliary organs; it is also added to medicines for summer-complaint, chronic diarrhea, remittent fever, etc. The dose is from half a fluidrachm to two fluidrachms, two or three times a day. Tinctura Lobelia. Tincture of Lobelia. Preparation.—Take of Lobelia, (the herb), four ounces ; Diluted Al- cohol two pints. Macerate for fourteen days, express, and filter throuo-h paper. This Tincture may also be prepared by adding Diluted Alcohol to the Lobelia, in powder, and allowing it to stand for twenty-four hours, or until thoroughly moistened, then transferring the whole to a displacer, and gradually adding to it Diluted Alcohol until two pints of filtered liquor have passed. Properties and Uses.—This Tincture possesses the same properties as Lobelia ; the dose is from thirty to sixty drops as a nauseant; and half a fluidounce, or more, as an emetic. A tincture prepared of equal parts of vinegar and alcohol, instead of diluted alcohol, is preferable to the above, in cases where it is not to be kept for a length of time. Exter- nally, the tincture of lobelia is beneficial as a local application in tetter, and similar cutaneous eruptions, stings of insects, and in the poisoning by Rhus. Tinctura Lobelia Composita. Compound Tincture of Lobelia. Dr. J. King's Expectorant Tincture. Preparation.—Take of Lobelia, (herb), Bloodroot, Skunk Cabbage Root, Wild Ginger Root, and Pleurisy Root, each, coarsely powdered, one ounce ; Water, (or Vinegar), one pint; Alcohol three pints. Mace- rate for fourteen days, express, and filter through paper. This Tincture may also be prepared from the same dry materials, in powder, by thoroughly moistening them with Alcohol diluted as above, allowing them to stand for forty-eight hours, then transferring them to a percolator, and gradually pouring upon them Alcohol diluted as above with Water, (or Vinegar), until four pints of filtered liquor have been obtained. Properties and Uses.—This Tincture forms an excellent emetic for chil- dren and infants, and may be safely used in croup, hooping-cough, bron- chitis, asthma, convulsions, and in all cases where an emetic is required. It will likewise be found beneficial as an expectorant, or nauseant in coughs, pleuritic affections, asthma, pertussis, and whenever expectorants are indicated. It is among the most valuable of Eclectic remedies. In croup, for children one year old, give half a tablespoonful m a tablespoonful of molasses, and repeat it every fifteen minutes, until it vomits; after which, a teaspoonful may be given every hour or two, as required—the vomit to be repeated two or three times a day. A child Tinctura. 1263 from two to six months old, may take from half to a teaspoonful for a dose ; less than two months old, from fifteen to twenty-five drops, to be repeated every ten minutes, if vomiting is required. Children from three to six years old, may take a tablespoonful, in molasses or warm water, every ten minutes, until it vomits. Warm boneset or thoroughwort tea, ought always to be given in order to facilitate its operation as an emetic. For cough, asthma, etc., to promote expectoration and remove tight- ness across the chest; and in all ordinary cases where an expectorant is required, adults may take one or two teaspoonfuls in half a wineglassful of slippery elm tea, three to five times a day, or as often as required. Children from one year old to ten, may take from half to a teaspoonful in the same manner; and for those less than one year, from ten to thirty drops. Should the above doses vomit, they should be lessened, except when vomiting is desired. The stomach and bowels must be kept reg- ular in all cases, by gentle medicines. Tinctura Lobelia et Capsici Composita. Compound Tincture of Lobelia and Capsicum. Antispasmodic Tincture. Preparation.—Take of Lobelia, Capsicum, and Skunk Cabbage Root, each, in powder, two ounces; Diluted Alcohol two pints. Macerate for fourteen days, express, and filter. This Tincture may also be prepared from the same dry materials, in powder, by thoroughly moistening them with Diluted Alcohol, allowing them to stand for forty-eight hours, then transferring them to a percola- tor, and gradually pouring upon them Diluted Alcohol until two pints of filtered liquor are obtained. Or, it may be made by combining together, equal parts of the satu- rated tinctures of Lobelia, Capsicum, and Skunk Cabbage Root. Properties and Uses.—This Tincture is a powerful antispasmodic and relaxant, and will be found highly efficacious in cramps, spasms, convul- sions, tetanus, etc. The dose is from half a teaspoonful to a teaspoonful, every ten or twenty minutes, or as often as the urgency of the case requires. In convulsions and tetanus, it may be poured into the corner of the mouth, and repeated as often as necessary ; generally, the effect is almost instantaneous. This valuable preparation should always be in the possession of every physician. In rigidity of the os uteri, a teaspoon- ful administered by mouth, or by enema into the rectum, and repeated in fifteen or twenty minutes, will be found to' produce a state of softness and dilatability without the necessity of using the lancet, so highly recom- mended by a certain class of practitioners, in such cases. Tinctura Lupulini. Tincture of Lupulin. Preparation.—Take of Lupulin four ounces; Alcohol two pints. Ma- cerate for fourteen days and filter through paper.— U. S. 1264 Pharmacy. Properties and Uses.—Lupulin is the active principle of hops, and as the quantity of it varies in different specimens of hops, a tincture of it is decidedly preferable to one made of hops. It may be employed with advantage in coughs, after-pains, and in all cases where opium is inad- missible. The dose is one or two fluidrachms in mucilage or sweetened water. Tinctura Mentha Viridis. Tincture of Spearmint. Spirits of Mint. Preparation. — Take of the fresh Herb of Spearmint a sufficient quan- tity to fill a glass jar, and cover with good Holland Gin. Macerate for seven days, express, and filter. Properties and Uses.—This Tincture is diuretic and stimulant. It may be beneficially employed in strangury, retention of urine, gravel, and various chronic nephritic diseases. The dose is from two to four ounces, three times a day; but in severe and painful cases it may be repeated every half hour or hour until relief is obtained. Externally, it forms an excellent application to hemorrhoids when in a state of inflammation; cotton must be moistened with it, and applied to the part. Tinctura Myrrha. Tincture of Myrrh. Preparation.—Take of Myrrh, bruised, four ounces; Alcohol three pints. Macerate for fourteen days and filter through paper.— U. S. Properties and Uses.—Tincture of Myrrh is chiefly employed as a local application to stimulate foul and indolent ulcers, and to promote the exfoliation of bones; and, diluted with water, it may be advantageously applied to spongy gums, aphthous sore mouth, and ulcerations of the throat; occasionally it is employed internally as an emmenagogue, and stimulant expectorant, in doses of from half a fluidrachm to a fluidrachm. Tinctura Myrrha Composita. Compound Tincture of Myrrh. Hot Drops. Preparation.—Take of Myrrh, bruised, eight ounces; Capsicum two ounces; Alcohol one gallon. Macerate for fourteen days and filter. Properties and Uses.—Eclectics very rarely employ this preparation internally; occasionally, however, it is used in cases of nausea, gastric distress, especially after a hearty meal, flatulence, etc., in doses of from half a fluidrachm to a fluidrachm in SAveetened water. Its internal em- ployment is contra-indicated when inflammation is present. Its principal use is externally, when it proves an excellent local application to sprains, bruises, fresh wounds, cuts, rheumatism, offensive ulcers, etc. Tinctura Nucis Vomica. Tincture of Nux Vomica. Preparation.—Take of Nux Vomica, rasped, two ounces; Alcohol eight fiuidounces. Macerate for fourteen days, express, and filter through paper. This Tincture may also be prepared by thoroughly moistening the Nux Vomica, in powder, with Alcohol, allowing it to stand for forty- Tinctura. 1265 eight hours, then transferring it to a percolator, and very gradually pouring Alcohol upon it until eight fluidounces of filtered liquor are obtained. Properties and Uses.—This Tincture possesses the properties of the nux vomica, but as the seeds vary in their quantity of active matter, it is an inferior preparation to the tincture of strychnia, or alcoholic extract of nux vomica. Its extreme bitterness is a great objection to its employ- ment. It is occasionally employed in doses of from five to twenty drops ; and as an external application in local paralysis. Tinctura Olei Anisi. Tincture of Oil of Anise. Essence of Anise. Preparation.—Take of Oil of Anise one fluidounce; Alcohol nine fiuidounces. Mix with agitation.—Dub.

Preparation.—Take of good Turkey Opium, sliced, twelve hundred grains; Boiling Water ten fiuidounces; Alcohol 76 p. ct., twenty fiuid- ounces. Pour eight fluidounces of the Boiling Water on the Opium, and with the hand or pestle, reduce it to an emulsion; then pour it into the bottle in which it is to be kept, rinse the pestle or hand with the remain- ing two fluidounces of Warm Water, and add it to the fluid in the bottle, together with the Alcohol. Agitate well, and set it aside ; in twenty- four hours it will be of full strength. (See Mr. Merrell's remarks on Tinctures, page 1241-2.) Properties and Uses.—This Tincture possesses the medicinal virtues of opium, and may be used in all cases where the drug is indicated, in doses of from ten to forty drops. Twenty-five drops are about equal to one grain of opium. If Diluted Acetic Acid be employed m the above formula instead of Water, it will form a much better tincture, and one less liable to vary in strength—the Tinctura Opii Acetata, or Acetated Tincture of Opium, and which may be given in the same doses as above. The following is offered to the profession by Eugene Dupuy, Pharma- ceutist, of NeAv York, as a substitute for McMunn's Elixir of Opium, (a trial of six years has been accorded to it, and none of the unpleasant effects attributed to Laudanum have as yet attended its administration): Take of Opium ten drachms, make it into a thin pulp with a sufficient quantity of water; then allow the mixture to stand in a cool place forty- eight hours; after which transfer it into an elongated glass funnel Tinctura. 1267 containing filtering paper, and add a superstratum of Water equivalent to the bulk of the whole mass. When twelve ounces of liquid have filtered, add to the filtered solution, Alcohol, 95 per cent., four ounces. The solution is an Aqueous Solution of Opium, nearly free from narcotina, preserved by alcohol, and contains about two-thirds of the substance of the Opium—the residue consisting chiefly of resin, narcotina, caoutchouc, ligneous matter, etc. For a similar purpose, the following mode of preparation is recom- mended in the American Journal of Pharmacy : Macerate ten drachms (Troy) of Opium, in half a pint of Water, for two days, and express; subject the dregs to two successive macerations, using six fiuidounces of Water each time, with expression; mix and strain the liquors, evaporate them to two fluidounces, and agitate the liquid with Sulphuric Ether four fiuidounces, several times during half an hour. Then separate the Ether by means of a funnel, evaporate the solution of Opium to dryness, dissolve the Extract in half a pint of Cold Water, pour the Solution on a filter, and after it has passed wash the filter with sufficient water to make twelve fluidounces of filtered Solution, to which add four fluidounces of Alcohol. By this process the Ether removes all that the Water has dissolved of the thebaina, the meconin, a part of the codeia, the odorous principle, meconate of narcotine, and fatty matter. The evaporation to dryness, and re-solution in Water, removes the ethereal odor, and separates a portion of acid, resin, and extractive. Tinctura Opii Camphorata. Camphorated Tincture of Opium. Pare- goric Elixir. Preparation.—Take of Opium one drachm, reduce it to an emulsion in Boiling Water one fluidounce, then add Benzoic Acid a. drachm ; Oil of Anise, a fluidrachm; Clarified Honey two ounces ; Camphor two scruples; Alcohol 76 per ct., twenty-two fluidounces; Distilled Water nine fluid- ounces. Macerate for fourteen days, and filter through paper. Properties and Uses.—This is a pleasant anodyne and antispasmodic; used to allay cough, in asthma, pertussis, chronic catarrh, and consump- tion; to relieve nausea and slight pains in the stomach and bowels ; to check diarrhea, and to procure sleep. The dose for an adult, is one or two fluidrachms; for an infant, from five to ten or twenty drops. The nostrums known by the names of Baieman's Drops, and God- frey's Cordial, two very dangerous articles in the hands of nurses and many non-professional persons, are generally prepared as follows: Baieman's Pectoral Drops, take Opium, in powder, Catechu, in powder, Camphor, Red Saunders, rasped, each, two ounces; Oil of Anise four fiuidrachms; Diluted Alcohol four gallons. Digest for ten or twelve 1268 Pharmacy. days. It is about equal in strength to the Camphorated Tincture of Opium, one fluidounce being about equal to two grains of Opium. Godfrey's Cordial. Dissolve Carbonate of Potassa two ounces and a half, in Water, twenty-six pints; add Molasses from the Sugar Refiners, sixteen pints, and heat over a gentle fire till they simmer; take off the scum which arises, and add a mixture of Laudanum a pint and a half, and Oil of Sassafras four fluidrachms. A fluidounce of this preparation contains rather more than a grain of opium. The coroner of Nottingham states, that " Godfrey's Cordial is given to children to a great extent; and that he has no doubt whatever that many infants are yearly destroyed in that borough, but who dying gradually, never come under his notice officinally." There can be no doubt of the truth of this assertion. At all events we can say positively that such instances occur elsewhere.—(Dunglison's Am. Med. Lib. and Intell., Jan. 1840, p. 299.)

Properties and Uses.—In the dose of three or four fluidrachms, this tincture will prove emetic ; and from ten to sixty drops will act as a nauseant, expectorant, stimulant, and alterative. As all the medicinal virtues of bloodroot are taken up by Alcohol, I do not see the necessity of using this liquid diluted. For several years past I have been accus- tomed to prepare this tincture with undiluted alcohol, which I have found to give a much better medicinal solution, and to be more satisfac- tory in its effects.

Troches or Lozenges are medicinal substances in powder, destitute of any very disagreeable flavor, which, by means of sugar and mucilage are incorporated into small, dry, solid masses, usually of a circular, flattened shape. As they are designed to be held in the mouth, and dissolved gradually in the saliva, they ought not, as a general rule, to he composed of medicines which act feebly, or require to be given in large quantities. Gum Arabic and Tragacanth are both employed, but the Trochisci. 1275 latter is preferred on account of the greater tenacity of its mucilage. The Dictionnuire des Drogues gives the following directions for preparing them: The best gum tragacanth having been selected, it is made into a mucilage with cold water, and strained ; the sugar bavino- been mixed with the other powdered ingredients, is thoroughly incorporated with the mucilage, by rubbing upon a marble slab, and is formed into a paste. This paste is then rolled out on the slab, its adhesion to the roller being prevented by powdering over it from time to time, a mixture of suo-ar and starch; and uniformity of thickness is effected by a frame of wood or iron, upon which the ends of the roller are placed. The extended layer of paste is again covered with the mixture of sugar and starch, and the troches cut by means of a tin-plate punch, which gives them the required shape and size. After exposure to the air for twelve hours, on paper, the troches are placed on a sieve to dry in a drying room or closet, and the superfluous powder remaining on them is removed by means of the sieve. Lozenges are frequently composed of extract of liquorice and gum Arabic with sugar, which renders them quite tough, so as to become unmanageable by long standing. In such cases the best mode is to thoroughly mix the articles together, and then add the sugar, in the form of a dense syrup, made with but two-thirds of the usual quantity of water required for simple syrup, mix it quickly, and while yet warm, roll the mass into long cylinders, and when nearly dry, cut them of the required size.

Ointments are Fatty Substances, containing the properties of certain medicines, and are designed for external use ; they are softer than cerates, being of a consistence resembling that of lard or butter, which renders them of easy application to the skin, by inunction. They are most commonly prepared with lard, which should be entirely free from salt and rancidity. Lard may be prepared for this purpose, by melting- it in twice its quantity of Boiling Water, stirring the mixture constantly; then setting it aside to cool, and separating the Lard when it has solidi- fied. This forms Prepared Lard, (Adeps Suillus Prceparatus). Sub- stances entering into the formation of Ointments, and which are not sol- uble in the fatty matter, should be very finely powdered previous to incorporation with it; or if they are soluble in alcohol or water, they may frequently be advantageously triturated and softened with a small quantity of one of these solvents, as with hard extracts, etc. When Ointments are long kept they are very apt to become rancid, hence, it is usually preferable to prepare them in small quantities at a time, or only when required for use. Either Benzoic Acid, or Poplar Buds, if not objectionable, or incompatible with the Ointment, will, when added to it, prevent, in a great degree the tendency to rancidity. Ten drops of the Spirit of Nitric Ether, incorporated with an ounce of Ointment, will remove the disagreeable, fatty odor of these preparations. According to Dr. C. W. Wright, Fats and Fixed Oils may be preserved free from rancidity and disagreeable odor for a long time, by melting them with powdered Slippery Elm, in the proportion of one drachm of the Bark to a pound of the Fat; after ten or fifteen minutes' application of heat, the Fat must be strained off. The Elm Bark communicates an odor to the Fat, that is scarcely distinguishable from that of the kernel of the hick- ory-nut. 1280 Pharmacy. Unguentum Acidi Muriatici. Ointment of Muriatic Acid.

Properties and Uses.—This is a mild anodyne. Useful as an applica- tion to irritable piles, painful glandular swellings, schirrous tumors, cancerous and other painful ulcers. The addition of one drachm of the Extract to one ounce of Lard, makes Unguent A. 1283 a more efficient preparation, as the heat employed in the preparation of the first formula, probably, impairs the virtue of the hemlock. Unguentum Creasoti. Ointment of Creosote. Preparation.—Take of Creosote half a fluidrachm; Lard one ounce. Mix them.— U. S. Properties and Uses.—This ointment is used in some cutaneous dis- eases, porrigo of the scalp, and as an antiseptic and stimulant to indo- lent or gangrenous ulcers. Unguentum Cucumis. Ointment of Cucumber. Preparation.—Take of Green Cucumbers (suitable for table use), seven pounds; Pure White Lard twenty-four ounces; Selected Veal Suet, cut in pieces, fifteen ounces. The unpared Cucumbers, after being washed, are to be reduced to a pulp by grating, and the Juice expressed and strained. The Suet is to be heated over a salt-water bath, until the fat is fused out from the membranes; then add the Lard, and when liquefied strain the mixture through muslin into a wide-mouthed earthen vessel capable of holding a gallon, and stir it until it commences to thicken, when one third of the Cucumber Juice is to be added and beaten with the ointment, by means of a wooden spatula, until its odor has been almost wholly extracted, and which will require several hours. Then allow it to stand until the fluid separates, which must be removed by decantation, and add another third of the Juice. This must be beaten in like manner until exhausted, then decanted, and finally the last third added, and similarly treated. The jar is then to be closely covered and placed in a water-bath, where it must remain an hour, or until the fatty matter entirely separates from the exhausted juice. The green albu- minous coagulum which floats upon the surface is then to be skimmed off, and the jar put aside in a cool place that the ointment may solidify. The crude ointment is then to be carefully separated from the watery liquid on which it floats, melted by a gentle heat, and strained—a part into a jar and closely sealed for keeping—the remainder into a mortar, and triturated with a little rose-water, until it is very white and creamy, for present use. It is usual to keep this ointment in glass jars without alloAving any unfilled interstices, and to cover it with rose-water to pre- vent the access of air. Thus prepared Cucumber Ointment readily keeps from season to season. Properties and Uses.—This forms an emollient application, very use- ful for chapped lips and hands, irritated and excoriated surfaces, etc. Unguentum Fuliginis. Ointment of Woodsoot.

Applied twice a day to enlarged tonsils, by means of a camel's hair pencil, it has caused the enlargement to disappear in the course of two months. It probably acts through the medium of absorp- tion. It is better to prepare it only as it is required for use. Unguentum Ipecacuanha. Ointment of Ipecacuanha. Preparation.—Take of Ipecacuanha, in powder, two drachms; Olive Oil two fiuidrachms; Lard half an ounce. Mix together Properties and Uses.—Rubbed on the skin for a few minutes, once or twice a day, this ointment produces an eruption.

Properties and Uses.—Tobacco Ointment forms an anodyne applica- tion, useful in various cutaneous eruptions, especially tinea-capitis, in irritable ulcers, painful swellings, etc. In using it, great care must be taken not to produce its constitutional narcotic effects, by employing too large quantities of it. An ointment made from the dried leaves is of but little value ; one made by rubbing twenty drops of the empyreu- matic oil of tobacco with an ounce of simple ointment, forms an active preparation. Unguentum Veratri Albi. Ointment of White Hellebore, Preparation.—Take of White Hellebore Root, in powder, two ounces; Oil of Lemons twenty minims; Lard eight ounces. Mix them.— U. S.

VERATRIA. Veratria. Preparation.—Take of Cevadilla, bruised, two pounds; Alcohol three gallons; Sulphuric Acid, Solution of Ammonia, Purified Animal Char- 1290 Pharmacy. roal, Magnesia, each, a sufficient quantity. Boil the Cevadilla in a gallon of the Alcohol, in a retort Avith a receiver attached, for an hour, and pour off the liquor. To the residue add another gallon of the Alcohol, together with the portion recently distilled ; again boil for an hour, and pour off the liquor. Repeat the boiling a third time with the remaining Alcohol, and with that distilled in the previous operation. Press the Cevadilla, mix and strain the liquors, and by means of a water-bath distil off the Alcohol. Boil the residue three or four times in Water acidulated with Sulphuric Acid, mix and strain the liquors, and evapo- rate to the consistence of syrup. Add Magnesia in slight excess, shake the mixture frequently, then express, and wash what remains. Repeat the expression and washing two or three times, and, having dried the residue, digest it with a gentle heat several times in Alcohol, and strain after each digestion. Distil off the Alcohol from the mixed liquors, boil the residue for fifteen minutes in Water with a little Sulphuric Acid and Purified Animal Charcoal, and strain. Having thoroughly washed what remains, mix the washings with the strained liquor, evaporate with a moderate heat to the consistence of Syrup, and then drop in as much Solution of Ammonia as may be necessary to precipitate the Veratria. Lastly, separate and dry the precipitate.— U. S. History.—By the above process, a Tincture of Cevadilla is first obtained, which is subsequently evaporated to the consistence of an extract, which contains the veratria combined with some vegetable acid. The veratria is dissolved from the extract by the acidulated water, which converts the greater portion of it into a sulphate; an excess of the native acid holding the remainder in solution. The sulphuric acid combines with the magnesia, when added, forming a sulphate of mag- nesia, while the veratria is precipitated, again dissolved by alcohol, and purified by evaporation. For further purification it is again dissolved in acidulated water, acted upon by animal charcoal, and finally precipi- tated by ammonia. A drachm of impure veratria is, by the above method, obtained from a pound of cevadilla. The veratria produced by this process, though sufficiently pure for medical purposes, is not wholly free from other principles; M. Couerbe states that Sabadillia and Veratrin are also contained in it. They may be separated as follows : To the solution of the impure sulphate of veratria obtained by the above process, add nitric acid, gradually, by drops, and decant the clear liquor from the abundant precipitate which ensues. To this liquor add a weak solution of potassa, which will also produce a precipitate; wash this precipitate with cold water, and dis- solve it in boiling alcohol. On evaporating the alcohol, the product yields the sabadillia to boiling water, which deposits it upon cooling; a resini-gum of sabadillia, so named by M. Couerbe remaining in solution. After the action of the boiling water upon the product, if this be again acted upon by ether, the veratria will be dissolved, and may be obtained Veratria. 1291 entirely pure by the spontaneous evaporation of the ether. The remain- ing undissolved resinous substance is called Veratrin by M. Couerbe. Sabadillia is a white, crystallizable, most intensely acrid substance, fusible by heat, readily soluble in hot Avater, but deposited upon cooling, very soluble in alcohol, and wholly insoluble in ether. It is capable of satu- rating the acids. Simon states it to be a compound of resinate of soda and resinate of veratria. Mr. Jas. Beatson, of the U. S. Naval Laboratory, N. Y., has given the following process for procuring veratria, which he considers superior to any other in use : Seventy-three pounds (avoirdupois) of sabadilla were rubbed upon a coarse wire sieve, which separated the seed from the capsules, and reduced to a coarse powder, in Swift's drug mill. Finding that a portion of the veratria was still retained with the mem- branous follicle, he also passed the capsules through the mill, which, from their elasticity, were but coarsely comminuted ; the finer portions he separated with a coarse sieve, and mixed with the ground seeds, moistened with alcohol, and allowed them to stand for twelve hours. He then introduced them into a displacement apparatus, and exhausted them thoroughly Avith rectified alcohol, in the following manner : Into the displacement apparatus he introduced thirty gallons of rectified alco- hol, and when a quantity had percolated sufficient to fill his still, he commenced distillation—returning the recovered alcohol into the dis- placement apparatus and continuing the percolation and distillation, until the seeds were thoroughly exhausted—collected all the alcohol he could from the exhausted seeds, and continued the distillation until the tincture, in the bottom of the still, was of a syrupy consistence, poured this, while hot, into eight times its volume of cold Avater, threAv the whole upon a calico filter, and washed with cold water, until the washings ceased to indicate the presence of veratria; mixed the washings with what passed first through the filter,and added liquor ammoniae in excess (about four pounds), which precipitated the veratria with a little of the coloring matter. Washed the precipitate with cold Avater which removed the greater portion of the coloring matter. Dried with a very gentle heat, and Avhen the moisture was completely expelled, eleven and a quarter ounces of pure veratria were obtained, with but a faint shade of coloring matter.—Am. Jour. Pharm., Vol. xxvi, p. 2, 1854. Pure Veratria is white, uncrystallizable, pulverulent, inodorous, ex- tremely acrid, fusible by heat, scarcely soluble in cold water, soluble in a thousand parts of boiling water, which it renders sensibly acrid, freely soluble in alcohol, less so in ether, neutralizing the acids, forming crystallizable salts with several of them, especially the muriatic and sulphuric. The ordinary commercial veratria is a grayish-brown or grayish-white powder, of an overpowering, bitter, acrid taste, producing a sense of tingling or numbness in the tongue, and powerfully irritating to the nostrils, causing, when admitted into them, violent sneezing and 1292 Pharmacy. mucous discharge. According to Couerbe the composition of sabadillia is C20 H13 O5 N, and that of pure veratria C31 H22 Oe N. Veratria may be used in the uncombined state, or united with acids, as in both forms it produces essentially the same effects. Veratria is uncrystallizable, fusible, combustible, entirely dissipated by a red heat, becomes intensely red upon contact with concentrated sulphuric acid, forms a yellow solution with nitric acid, and its solution in dilute acetic acid gives white precipitates with ammonia and the infu- sion of galls. Properties and Uses.—Veratria is a powerful irritant, capable of pro- ducing inflammation in the parts to which it is applied, and extending a peculiar action to the nervous system. Rubbed upon the skin it excites a sensation of warmth, and a peculiar tingling, which, when the applica- tion is continued for a considerable length of time, extends, according to Turnbull, over the whole surface of the body. Sometimes an evanescent blush is produced, and still more rarely, an eruption upon the skin; but, according to the same author, no marks of inflammation are, in general, evinced. Upon the denuded cutis, however, veratria and its salts are powerfully irritating, so much so as to prevent their advanta- geous application in this way. In the mouth and fauces, they produce an almost insupportable sense of acrimony; and snuffed up the nostrils, excite violent sneezing. Magendie informs us that when taken inter- nally, in the dose of a quarter of a grain, they promptly produce abun- dant alvine evacuations, and in larger doses, provoke more or less violent vomiting. Dr. Turnbull, on the contrary, says that he has very seldom found them to purge, even when largely administered, and that not unfrequently a state of constipation comes on during their employment, requiring the use of aperient medicine. According to this author, their first effect, when given in moderate doses, is a feeling of warmth in the stomach, gradually extending itself over the abdomen and lower part of the chest, and ultimately to the head and extremities. If the medi- cine is continued, this feeling of warmth is followed by a sense of tingling, similar to that produced by the external use of the medicine, which manifests itself in different parts of the body, and sometimes over the whole surface, and is frequently accompanied by perspiration, and some feeling of oppression. Occasionally, also, diuresis is produced. A still further continuance of the medicine, or the use of large doses, excites nausea and vomiting. It occasions no narcotic effects. The diseases in which veratria has been employed are chiefly gout, rheumatism, and neuralgia. Dr. Turnbull has found it useful, also, in dropsy, and in diseases of the heart, particularly those of a functional character. He thinks he has also seen it do good in organic diseases of this organ, but chiefly by acting as a diuretic, and thereby removing effusion in the pericardium. For internal use, the salts of veratria are Vina Medicata. 1293 preferred. From one-twelfth to one-sixth of a grain may be given in the form of pill, and repeated every three hours till the effects of the medicine are experienced. Dr. Turnbull prefers the tartrate, as less disposed to irritate the stomach. The sulphate or acetate, however, may be used. Any one of these salts may be readily prepared by treat- ing veratria with water, acidulated with the acid to perfect neutralization, and then evaporating to dryness. But veratria is much more employed externally than by the stomach, and is applicable, in this way, to all the complaints already mentioned. It may be used either dissolved in alcohol, or rubbed up with lard, or other unctuous substance, in the proportion of ten to twenty grains or more to the ounce. Of the ointment thus prepared, Dr. Turnbull directs a portion, of the size of a large nut, to be rubbed upon the skin, over the part affected, night and morning, from five to fifteen minutes, or until the more urgent symptoms are relieved. Veratria may be used in this way to the amount of from four to eight grains a day. Care must be taken that the cuticle is sound over the parts to which it is applied. When the skin is irritable, smaller quantities than those above mentioned must be used.— U. S. Disp. VINA MEDICATA. Medicated Wines. By Medicated Wines we mean the tinctures of those medicinal agents which are insoluble in water, or which do not require as stimulant a solvent as rectified or proof spirit, but which are capable of yielding their virtues to wine, either pure or diluted. As a general thing vinous tinctures are much inferior to alcoholic, on account of their liability to undergo decomposition, and the uncertainty of their strength, and should, therefore, be prepared in small quantities, without heat, and kept in well stopped bottles in a cool place. Bitters and cordials have, heretofore, been among the prominent medical agents peculiar to Eclectic practice, a few of which are yet retained, and some of which we have placed under the present head in order to avoid the introduction of a new class of pharmaceutical preparations ; yet, from the consequences following a course of treatment by bitters, viz : the cultivation of a taste or appetite for alcoholic stimulus, it is to be hoped, that even these will eventually be dispensed with for means and preparations fully as efficacious, and Avithout the evil results which sometimes occur from their use. Wines owe their solvent properties to the alcohol which they contain, as well as to acid which they usually hold in greater or less proportion ; and in the selection of them for medical purposes, the purest qualities only should be selected —those most commonly employed are Sherry, Madeira, and Teneriffe. Sherry Wine is preferable to all others in pre- paring medicated wines, as being less liable to change or decomposition; 1294 Pharmacy. probably native wine would answer, but it has not been fully tested in these preparations. Vinum Cinchona Compositum. Compound Wine of Peruvian Bark. Preparation.—Take of Peruvian Bark two ounces; Wild Cherry Bark, Sulphur, of each, one ounce; Cinnamon, Cloves, Nutmegs, of each, one drachm ; Sherry Wine, or Native Wine four pints. Macerate for seven days and filter. Properties and Uses.—This is a valuable agent in intermittent fever, and in chronic diseases attended with symptoms of a periodical charac- ter. The dose is two fluidounces, every one, two, or three hours, during the intermission. It is at present superseded by other preparations. Vinum Colchici Radicis. Wine of Colchicum Root. Preparation.—Take of Colchicum Root, well bruised, a pound; Sherry Wine two pints. Macerate for fourteen days, with occasional agitation ; then express strongly and filter through paper. Wine of Colchicum Root may also be prepared by macerating as above, then transferring to a percolator, and, after the liquor has ceased to pass, pouring «o much Wine upon the residue that the filtered liquor obtained may measure two pints.— U. S. Properties and Uses.—The bulb of Colchicum which is imported into this country is very variable in strength, and the only method by which an active vinous solution of it can be ensured, is to use it in large propor- tion, as given in the formula, so as to be certain of procuring a saturated preparation. It is employed by some practitioners in gout, gouty rheu- matism, and neuralgia, and will be found more decided in its influence, if given in connection with magnesia or its sulphate. In neuralgia it maybe beneficially administered in combination with solution of sulphate of morphia. Overdoses may occasion serious results. The dose is from ten minims to a fluidrachm, three or four times a day, or oftener in severe cases, until its peculiar effects have manifested themselves. Vinum Colchici Seminis. Wine of Colchicum Seed. Preparation.—Take of Colchicum Seed, bruised, four ounces; Sherry Wine two pints. Macerate for fourteen days, with occasional agitation ; then express, and filter through paper.— U. S. Properties and Uses.—The seeds of Colchicum being of more uniform strength, and not so liable to injury as the bulb, do not require therefore to be used so largely in proportion to their menstruum as the bulb. This medicated wine may be employed for the same purposes as the wine of the bulb, or the tincture of the seeds. In overdoses it is capa- ble of producing death. The dose is one or two fluidrachms. To obtain their full medicinal activity the seeds should always be bruised. Vinum Ergota. Wine of Ergot. Preparation.—Take of Ergot, bruised, two ounces ; Sherry Wine a pint. Vina Medicata. 1295 Macerate for fourteen days, with occasional agitation; then express and filter through paper.— U. S. Properties and Uses.—This may be used during labor, as a parturient, in doses of two or three fluidrachms ; in other instances it may be given in doses of one or two fluidrachms, three or four times a day, and gradu- ally increased if desirable. Vinum Hamatoxyli Compositum. Compound Wine of Logwood. Golden Tincture. Preparation.—Take of Logwood Chips, Black Hellebore, bruised, of each, four ounces; Sherry Wine three pints. Macerate for fourteen days, express, and filter. Properties and Uses.—This is cathartic, tonic, and emmenagogue, and will be found useful in chlorosis, amenorrhea, and some forms of dys- menorrhea. The dose is from half a fluidounce to two fluidounces, three times a day. Vinum Hydrastis Compositum. Compound Wine of Golden Seal. Wine Bitters. Preparation.^—Take of Golden Seal Root, Tulip Tree Bark, Bitter Root, of each, bruised, one drachm; Capsicum half a drachm; Sherry Wine four pints. Macerate for fourteen days, with occasional agitation; then express, and filter.—T. V. M. This vinous solution may also be prepared from the same dry mate- rials, by covering them with Sherry Wine, allowing them to stand for one week, then transferring them to a percolator, and gradually adding Sherry Wine until four pints of filtered liquor are obtained. Properties and Uses.—This forms a pleasant bitter tonic solution ; it may be administered in dyspepsia and other complaints, where tonics are indicated. It is sometimes improperly made of Malaga Wine. Dose, from half a fluidounce to two fluidounces, three times a day. A similar preparation is recommended by some authors. Take of Golden Seal Root, Tulip Tree Bark, Bitter Root, Orange Peel, each, one drachm; Prickly Ash Berries, in powder, half a drachm; add Boiling Water half a pint; Pour the Boiling Water on the rest of the articles mixed together, and let them stand in a closely covered vessel for twenty- four hours, and add Malaga Wine one pint and a half. (Good sweet Native Wine would he better.) Dose, same as above. Vinum Ipecacuanha. Wine of Ipecacuanha. Preparation.—Take of Ipecacuanha, bruised, or in powder, two ounces; Sherry Wine two pints. Macerate for fourteen days, with occasional agitation; then express and filter through paper. Wine of Ipecacuanha may also be prepared by moistening the Ipeca- cuanha, in coarse powder, thoroughly with Wine, allowing it to stand 1296 Pharmacy. for twenty-four hours, then transferring it to a percolator, and pour- ing Wine gradually upon it until two pints of filtered liquor are obtained.— U. S. Properties and Uses.—This wine possesses all the medical qualities of the root, and as an emetic is sometimes preferred in infantile cases. It may be used also as an expectorant or diaphoretic. Dose, as an emetic for an adult, a fluidounce; for a child one or two years old, a fluidrachm, repeated every fifteen minutes till it operates; as an expectorant and diaphoretic, from ten to thirty drops. Vinum Phytolacca Compositum. Compound Wine of Poke. Rheu- matic Liquid. Preparation. — Take of Inspissated Juice of Poke Berries, White Turpentine, of each, four ounces; Sherry or Native Wine two gallons. Macerate for fourteen days, with occasional agitation, and filter. Properties and Uses.—This is an excellent preparation for chronic rheumatism, chronic gonorrhea, syphilitic pains, etc. The dose is from half a fluidounce to a fluidounce, two or three times a day. Vinum Sambuci. Wine of Elder. Hydragogue Tincture. Preparation.—Take of Elder Bark, bruised, one pound; Sherry Wine, or Native Wine one gallon. Macerate for fourteen days, express, and filter through paper. This medicated wine may also be prepared by macerating powdered Elder Bark, in Wine, for twenty-four hours, then transferring it to a per- colator, and gradually adding Wine until one gallon of filtered liquor is obtained. Properties and Uses.—Wine of Elder is useful in dropsical affections, especially ascites, and dropsy supervening upon scarlatina or other exanthematous diseases. Dose, two ounces, three or four times a day. This preparation may be made for immediate use by digesting the articles with heat for an hour. Vinum Symphyti Compositum. Compound Wine of Comfrey. Res- torative Wine Bitters. Preparation.—Take of Comfrey Root, Solomon's Seal Root, Spikenard Root, of each, bruised, one ounce; Chamomile Flowers, Colombo Root, Gentian Root, of each, bruised, half an ounce; Sherry Wine four pints; Boiling Water a sufficient quantity. Place the Herbs in a vessel, cover with Boiling Water, and let the compound macerate for twenty-four hours, keeping it closely covered; then add the Sherry Wine. Macerate for fourteen days, express, and filter. Malaga Wine, or Metheglin, which are sometimes used in this prepa- ration, are inferior to Sherry Wine, and more liable to decomposition. The addition of Sugar to this Wine of Comfrey, is very apt to disagree with many persons, and thus destroy its efficacy. Vina Medicata. 1297 Properties and Uses.—This is a most valuable tonic in all diseases peculiar to females, especially leucorrhea, amenorrhea, weakness of the back, etc. The dose is from half a fluidounce to two fluidounces, three or four times a day. A similar preparation, made as follows, is also recommended: Take of Spikenard Root, Solomon Seal Root, Gentian, Wild Cherry Bark and Peach Root, of each, bruised, one ounce; add Boiling Water four pints, simmer slowly to one pint; then add Native Wine four pints. Macerate for seven days, express, filter, and add Loaf Sugar two ounces. Dose, as above. I have just seen some specimens of what are called " Concentrated Remedies," purporting to have been manufactured at some establish- ment in the city of New York; among them were Cypripedin, Senecin, Stillingin, Irisin, etc., each in the form of powder, together with several other reputed concentrated powdered preparations. Upon an examina- tion, I find several of these agents to be sugar of milk triturated, proba- bly, with oils, oleo-resins, or saturated tinctures. There certainly can be no objection to the trituration of concentrated principles with sugar, or sugar of milk, for, I believe, they are frequently employed in this manner by many Eclectics ; but when such triturations are represented and sold at exorbitant prices as the genuine concentrated principles themselves, and at the same time veiled with a semblance of science, scientific research, and purity of intention, every honest mind will find, in such a course, much to condemn, and every well-wisher of Eclecticism must object in the strongest terms. The imposition is an insult to Eclec- tics, and to say the least of it, is by no means creditable to the reputation or honesty of the manufacturers. Such a course, if not eschewed and censured, is not only calculated to diminish the confidence of our own practitioners in the value of concentrated medicines, but, when they are employed or tested by physicians of other schools, as we know to be fre- quently the case, it must cause a prejudice against them as inactive or worthless agents, as well as give rise to no very exalted opinions of Eclectic honesty, science or acuteness. Remedies for general professional use, whose method of preparation is kept from the profession, should never be countenanced by its members, because it is impossible to know what they really are, to determine their positive value, or to decide to what extent dishonesty and imposition may be connected with them. It is greatly to be desired, therefore, that all friends of Eclecticism will be upon their guard relative to this matter, and that they will likewise take especial pains to caution those of other schools, who have the liberality and manly independence to fairly and impartially test the value and utility of our remedies, in order that Eclecticism may not be misrepre- sented or falsified by any impositions of the sort.—/.

COMPARISON OF THE DIFFERENT THERMOMETRY SCALES. The Thermometer always used in this country is that of Fahrenheit; it is also used in parts of Germany. In this instrument the range between the freezing and boiling points of water is divided into 180°, and as the greatest possible degree of cold was supposed to be that produced by mixing snow and salt together, it was made the zero. Hence, the freezing point became 32°, and the boiling point 212°. Table of Proportionate Doses. 1315 The Centigrade thermometer places the zero at the freezing point of Avater, and divides the range between the freezing and boiling points into 100°. This scale has long been used in Sweden, under the title of Celsius's thermometer, and is generally adopted on the Continent. Reaumur's thermometer, which was formerly used in France, divides the space between the freezing and boiling points of water into 80°, and places the zero at the freezing point. It is now little employed. Le Lisle's thermometer is used in Russia. The graduation begins at the boiling point, and increases toward the freezing point. The boiling point is marked 0°, and the freezing point 150°. To convert the degrees of Centigrade into those of Fahrenheit, mul- tiply by 9, divide by five, and add 32. To convert the degrees of Centigrade into those of Reaumur, multi- ply by 4, and divide by 5. To convert the degrees of Fahrenheit into those of Centigrade, deduct 32, multiply by 5, and divide by 9. To convert the degrees of Fahrenheit into those of Reaumur, deduct 32, divide by 9, and multiply by 4. To convert the degrees of Reaumur into those of Centigrade, multi- ply by 5, and divide by 4. To convert the degrees of Reaumur into those of Fahrenheit, multi- ply by 9, divide by 4, and add 32. TABLE OF PROPORTIONATE DOSES FOR DIFFERENT AGES. GAUBIUS' TABLE. Examples.

To the above rule there are certain exceptions; thus castor oil requires to be given in larger proportionate doses, while opium and the narcotics generally should be administered in smaller proportionate quantities. Sex, temperament, and idiosyncracy have also a modifying effect upon the dose, and they should always be kept in view in the administration of medicines. Females usually require smaller doses than males; and persons of sanguine temperament bear depletory medicines better than the phlegmatic.

TABLE EXHIBITING THE NUMBER OF DROPS OF DIFFERENT LIQUIDS EQUIYA- LENT TO A FLUIDRACHM. Liquid medicines, in small quantities, are frequently estimated by drops, which are often incorrectly considered equivalent to a minim, or the sixtieth part of a fluidrachm. The drop of water and of watery fluids is, on an average, about this size; but this is by no means the case with all liquids. Even in the same liquid the size of the drop varies, accord- ing to the shape of the vessel, and of its mouth, from which it is dropped. The following table was compiled by Mr. E.

Carbonated Waters, are such as contain an excess of carbonic acid, which gives them a sparkling appearance and the power of redden- ing litmus paper. These waters frequently contain the carbonate of iron, lime and magnesia, whieh are held in solution by the excess of carbonic acid, and which are deposited when the water is boiled, or ex- posed for some time to the air.

III. Chalybeate Waters are characterized by their inky taste, and by striking a blue-black color with an infusion of galls, and a blue color with ferrocyanuret of potassium. The iron is generally in the state of carbonate of the protoxide, held in solution in the water by excess of carbonic acid. By standing or boiling, the carbonic acid is driven off, and the protoxide, by absorbing oxygen, is precipitated as a hydrated sesquioxide, of an ochreous color. Total,...... 1.491 Magnesia Springs.

TKMPIORATUKES TO BE OBSERVED IN CERTAIN PHARMACEUTICAL OPERATIONS. In the fermentation of saccharine solutions, the highest temperature should not exceed 86°. (Thomson.) The lowest temperature at which they will ferment is 38°. (Thomson.) The process of acetous fermentation is best conducted at a temperature of above 86°. The temperature requisite to coagulate albumen varies with the state of dilu- tion. If the quantity of albumen be so great that the liquid has a slimy aspect, a heat of 145° to 150° suffices, but in a very dilute condition, boiling is required. (Fownes.) In the London and U. S. Pharmacopoeias: When a boiling heat is directed, a temperature is meant of 212°, F. When a gentle heat is directed, a temperature is meant of from 90° to 100°. The specific gravities of substances ordered in the London Pharmacopoeia, are to be taken at a temperature of 62°. A water-bath is that by which any substance, contained in a proper vessel, is exposed either to hot water, or the vapor of boiling water. A sand-bath is made of sand, to be gradually heated, in which anything is placed contained in a proper vessel. Syrups are to be kept in a place where the temperature never exceeds 55°. Vegetables, shortly after they have been gathered, those excepted which ought to be fresh, are to be lightly strewed, and dried as quickly as possible, with a gentle heat (90° to 100°); keep them afterward in proper vessels, excluded from the access of light and moisture. In the Dublin Pharmacopoeia: By the term superior heat, is meant some degree between 200° and 212°. When a medium heat is directed, a temperature is meant between 100° and 200c. When an inferior heat is directed, a temperature is meant between 90° and 100°. In the process of digestion, an inferior heat is to be applied, unless it should be otherwise directed. In the process of maceration, a heat should be applied between 60° and 90°. In the Dublin, Edinburgh, and U. S. Pharmacopoeias: Whenever mention occurs of the specific gravity of any body, its tempera- ture is supposed to be at 60°.
