BY W. L. SUTTON, M. D. LOUISVILLE: I'RENTICE AND W E I S S I N 50 of iodine in scrofulous complaints and as to its mode oi action. I am disposed to place it among the tonics,* when used in such a manner as to be serviceable. Hence Lugol and some others declare that during its administration the appetite improves and the body increases in weight. But we are assured by others that it produces irritation of the stomach and emacia- tion of the body. I apprehend that at this day there is no difficulty in believing that any article may be so managed by different persons as to produce dissimilar or even opposite ef- fects. I believe that much of the discrepancy of testimony as to the effects of iodine, is due to the different modes in which it is used. I can well believe that, used in the quanti- ty of a grain a day, it may act as a tonic, and in the quantity of five or six grains daily it may act as an irritant. To set this matter in a proper light, I have thought it worth some trouble to collate a number of formulas for the administra- tion of iodine, and to calculate the quantity of that article given for a dose according to each formula. I shall premise 3i. of a watery solution dropped from a two ounce vial gives about sixty drops, of an alcoholic tincture about 140 drops, of an ethereal tincture about 1 80 drops. Varieties to a con- siderable extent will take place, occasioned by the purity of ♦Note.—Some physicians think that the tonic effects of iodine are ex- erted principally or wholly on the absorbents, thus enabling them to take up the morbid deposit. Others say, that this effect is produced by its ac- tion as an alterative, the action of the absorbents being not only increased but altered. Others again consider it as a deobstruent. I certainly think an appropriate name a very important thing; but unfortunately in medi- cine, as in other departments of philosophy, men will sometimes express the same idea by different words, and sometimes different ideas by the game words. It is very important, then, that we understand correctly the idea intended to be conveyed. My idea then is, that administered in suit- able doses and under appropriate circumstances, iodine increases the ap- petite and promotes digestion, furnishing a more healthy chyle; that, in consequence, the various organs of the body are enabled to take on a more healthy action; that the nutrient vessels being furnished with a better ma- terial for assimilation, are also enabled better to select the most appropriate molecules. As a consequence of the restoration of healthy action, any effete or deleterious corpuscles, deposited in the texture, are taken up and removed. In this way it may be held to act both as an alterative and a de- obstruent; but I conceive that its whole action may be referred to its tonie powers. 51 the alcohol and ether, also by the size of the rim around the mouth of the vial, and especially by the fluid running back so as to touch the neck of the vial before it drops.

It will be observed that in the foregoing estimate of the pre- parations of iodine, I have not taken into consideration that which is present as an ingredient of the iodide of potassium. It appears that iodine is very much modified by combination with other articles, as it can be used in much greater quanti- ties when thus combined than in its pure state. Thus it is verv irritating when used in the form of a pill or tincture, be- cause of its local action. Indeed, I do not think it ought ever to be used in either form. By being dissolved, by the aid of iodide of potassium, it is much more manageable; by being combined with potassium, iron, &c, it can be taken in much larger quantities, so much so, that Lugol considers the iodide of potassium simply as a solvent for iodine, although there is half as much more iodine in the solvent as is dissolved in it. 53 Not being qualified to state the relative value of the two, I have gone upon the supposition that Lugol is right in consid- ering the iodine as of little activity. It may be remarked that although the 10th formula directs only from ^ to ^ or i, ^ of a grain of iodine thrice a day, yet Drs. Morton* and Ellis direct us to diminish the quantity if it 'produce dizziness, pain in the bowels, or other unpleasant symptoms.' If caution is necessary in using that preparation, it would seem much more called for in a large majority of them. No directions are appended to some of the formulae, so that we cannot say what amount is intended to be taken daily; but we may presume, when not otherwise directed, thrice daily. By this calculation (leaving out of the account the latter directions appended to the 8th formula as ambigu- ous,) we have the daily quantity from li (10th formula) to 6 grains (7th formula). I believe, as indeed is believed by others, that Lugol has been more successful in the employ- ment of this article than others, because he has used it in moderate doses, and has paid great attention to other means of improving the health, as exercise, clothing, diet, &c. Many physicians, both of Europe and America, declare most unequivocally that they have never seen it do good. As to the mode in which they used it, as well as the suitableness of the cases for its use, we know little. One thing, however, I do know, viz: that men eminent in the profession have their prejudices and caprices as well as their more humble brethren. And when they have been foiled, in consequence of having used an article in a case not adapted to its employment, they are no less apt to denounce the remedy. In the successful employment of any remedy, much depends upon its being properly prepared, and many medicines have fallen into un- merited neglect from a want of attention to this circumstance. I apprehend that this is as emphatically true of iodine as of any remedy under the sun. I have seen a gentleman occupying an exalted station in the profession who used the tincture of iodine freely, and kept it as an officinal preparation. Now I ""Illustrations pul. consumption, p. 130. 54 apprehend that this is the most objectionable mode of adminis- tering the article. At least I have never given it without pro- ducing irritation of the stomach and vomiting, occasioned, doubtless, by the decomposition of the tincture by coming in contact with water. I presume the gentleman above mention- ed escaped producing much irritation, by having his tincture pretty well decomposed by age before it was administered. But what reliance is to be placed upon experience of this character? If we employ it, let it be in some form in which it is not liable to be set free, and thus produce disorder of the stomach, as a solution with hydriodate of potash. A combination of these last two articles, namely, iodide of iron, would seem to promise much in a disease in which each is so valuable. I apprehend, however, that the proportion of iron is too small for us to expect much from that. "When we wish to employ the two articles in the same case, I think we had better use a solution of iodine, and give Vallet's ferruginous pill in addition. We can thus give just as much of each arti- cle as we please. I have employed the article, and apparent- ly with benefit, though I do not know that any better result attended the administration than would have attended the use of iodine. No article in the materia medica requires to be pre- scribed more carefully than this; and no physician ought to administer it without knowing its purity. He cannot send to an apothecary for it with any assurance of getting what he wants, at least such has been my experience. I have never seen the article that did not contain sesqui-oxide and sesqui- iodide. The sesqui-iodide is greatly more active, and when given under the impression that we are giving the iodide, nev- er fails to irritate the stomach. The syrup of iodide of iron is said to keep well, yet would I be afraid of that if not fresh. Perhaps the least objectionable formula for this article is that of pills as recommended by Christison, to-wit: R. iodine 127 grains, clean soft iron wire fss., distilled water 75 minims; agitate briskly in a strong vial with a glass stopper until the froth becomes white; pour the liquid upon two drachms of finely powdered loaf sugar in a mortar; triturate briskly for a 55 few minutes; add gradually a powder composed of liquorice powder ^ss., pulv. gum arabic 3iss., flour 3i. mix., divide into 154 pills. Each pill contains one grain of the iodide. During agitation this preparation evolves a very considerable amount of heat, so that it is necessary to envelope the vial in a cloth. So much gas is evolved also as to require great care that the stopper be not displaced and a portion of the ingre- dients lost. Whilst we thus attend to improving the general health, we should also have an eye to the local affection. To remove it, volatile liniment will frequently be sufficient. If somewhat obstinate, some of preparations of iodine may be used topical- ly. Hydriodate of potash in the proportion of 3i. to §i. of nice lard. If a more stimulating article is needed, from 3 to 10 grains of iodine may be added. It will be seen that it will not do to rely upon emetics, ca- thartics or tonics exclusively; neither can we depend upon them altogether, however judiciously combined. We must call to our aid means more properly hygienic than medicinal. In the first place, I will mention bathing. Cleanliness must of course be insisted on, but bathing, properly used, is a very important means of improving and preserving health. Scarce- ly any circumstances preclude the occasional use of the warm bath. It removes slight irritations, and produces a train of pleasurable sensations highly conducive to health. A moder- ate quantity of salt added to the bath will make it more effec- tual in stimulating the skin; or the surface may be rubbed dry with a towel which had previously been wrung out of salt water and dried. If we wish to make the bath medicinal, we may use a solution of iodine as recommended by Lugol. Cold bathing is less universally applicable, and should always be commenced with caution. Rules by which we may judge of its usefulness and safety have been already mentioned. If it can be used safely, it will almost certainly be beneficial. What has been said as to the means of preserving health un- der the head of predisposition, applies with much increased force here. 5 * 56 Having gone so fully into the mode proper in the treatment of enlarged lymphatic glands, which applies very generally to what is usually denominated the different forms of sciofula, I will dismiss this branch of the subject with some general ob- servations. 1st. All affections, whether considered scrofulous or not, occurring in persons of a strumous diathesis, bear de- pletion worse and tonics better than the same affections oc- curring in healthy constitutions. 2d. Parts affected with in- flammation bear exercise better; thus in scrofulous ophthalmia it is not so necessary to exclude the light as in common oph- thalmia, nay, a certain amount of light is beneficial. Again, scrofulous white swelling, after the acute stage is over, is benefitted by exercising the limb moderately. I have seen a case in which the tibia was denuded for 10 or 12 inches in length, and over full four-fifths of its circumference improve with great rapidity whilst the patient was permitted, after some constitutional treatment suited to the first stage, to walk upon it daily. 3d. That during our treatment inflammation of some part may be set up. Whilst this continues, we must intermit our tonic course until, by appropriate means, we shall have subdued this inflammation, and then resume it. 4th. That whilst we attend to constitutional treatment, we must not fail to make such topical applications as may be suited to each particular case. 5th. That much time is ne- cessary to manage these cases successfully. We cannot, if we would, make a great revolution in the constitution in a short time; and if we could, we should probably produce an evil equal to the one we cure. A neglect of this considera- tion has been the means of much injury to patients, and of much discredit to remedies. We try to do too much in a short time. As a friend of mine thought, for whom Fowler's solution of arsenic had been prescribed for intermittent fever. As the next paroxysm was very much mitigated, he said, '■it a little is good, a good deal is better,' so took half an ounce. bth. It is confessedly very difficult to appreciate correctly the effects of remedies in this disease. There is not so much dan- ger in misconceiving the immediate effects of our remedies. 57 when given in decided doses, but when they are given in small doses for a long time, the case is very different. I think I have seen the effects of such treatment appear weeks after it had been discontinued; at least, if the amendment was not occasioned by that treatment, it was the effect of the powers of nature, for no other remedies had been employed. It is easy to conceive how the employment of another medicine, about this time, might give rise to very erroneous opinions as to the effects of each. 7th. To all of the exclusive modes of treatment, I would apply one remark. That so far as they are exclusive, they are wrong; yet when used with discrimi- nation, and under proper circumstances, each one may be made very useful. Even the cura famis, when used to a certain degree and continued for a short time, may be the means of strengthening the digestive powers, and therefore beneficial. But if carried too far, it proves hurtful. And I think it quite probable that much of the credit which this mode enjoyed was acquired by the inability of the patient to pursue the treatment to the degree prescribed, and his un- willingness to inform his physician of the fact. A case direct- ly in point came to my knowledge a short time since. An eminent member of the profession thought himself entitled to some credit in consequence of a cure effected in this way. The patient, however, put a different construction upon the affair. He said he stood the low diet as long as he could, but gave it up. 'Tis true he took the soup and gruel as prescribed, but he took the beef and potatoes, bread and milk likewise. Treatment of Scrofula.—Although we cannot expect to cure scrofula often, yet we shall occasionally meet with cases in which the diathesis is weak, and the accumulation of tu- bercular matter circumscribed, in which we may hope to wit- ness a restoration to health. Whether that restoration be a cure or a recovery is perhaps doubtful. Even in cases where no restoration is to be hoped for, still we may mitigate the sufferino-s and prolong the life of the patient. Besides, al- 58 though we may be satisfied that in the present state of our knowledge we cannot cure a given disease, we should not con- clude that we shall never be able to cure it. Every physician should have for his motto, '•Nil despcrandum? The general constitutional plan of treatment, before and after the develop- ment of tubercles, will not vary much. The same observance of hygienic rules will be necessary. Cold bathing will be less likely to be borne with benefit. More care in diet will be ne- cessary. Medicine, though more necessary, will be less effec- tual. The accumulation of tuberculous matter may be in any tex- ture or in any organ of the body; but wherever situated, it constitutes scrofula, and is a fearful disease. Perhaps the most frequent seats are on the surface of the mucous mem- branes, in the parenchyma of the lungs, the lymphatic glands, the spleen, peritoneum and bones. Whilst we continue the treatment heretofore laid down, we must also be diligent in applications intended to benefit the local affection, especially if it should not appear that there are deposits in various parts. If the lymphatic glands should be most prominently affected, rubbing the surface over them with some of the ointments of iodine may be tried; or blisters over the gland, to be kept dis- charging and removed as often as may be necessary, will sometimes discuss the swelling. It will frequently be very difficult to say whether such swollen glands are truly tuber- cular, especially before fluctuation is evident. We must judge from the doughy feel of the tumor and the evidences of tu- bercular matter in other situations. When such deposit is found the means used to discuss the tumor will be less likely to succeed, because we have the presence of a foreign body to contend with. If such body is removed by the absorbents, it will require considerable time. If suppuration take place, after the matter is discharged we may still rub the adjacent parts with some of the preparations of iodine. We shall pre- sently find a considerable portion of the surface of the tumor converted into an ulcer. This should be bathed with salt water a solution of iodine, or one of creasote. If it should not im- 59 prove under this treatment, it should have a blister laid on its surface for half an hour, or as long as the patient can con- veniently bear it. This application should be repeated as may appear necessary. Dressing daily with an ointment of sul- phate of copper, two scruples to the ounce, for a week, to be suspended for the same period and then repeated, will like- wise be a proper dressing. If the deposit should be in the lungs, in addition to the gen- eral treatment, we should institute counter irritation some- where about the chest. This may be effected by blisters re- peatedly applied, by pustulations with tartaremeticointment, or by setons. Patients are very apt to get tired of blisters and pus- tulations. For that reason, perhaps, it would be better to rely on setons. Just here I may mention the use of cod liver oil, which has been highly extolled by Pereyra, Physician to Hos- pital St. Andrew, Bourdeaux, as a remedy in tubercular phthisis. It has also been considered very serviceable in other forms of scrofula. I do not doubt but it is a remedy suitable for scrofula, the more especially as it contains iodine in its com- position. Whether all its virtues are dependent upon the iodine, or whether the iodine exists in a combination more adapted to benefit scrofulous disease, I am not prepared to say. We should observe, however, that the only case given by him, which I have seen, (Med. Chir. Rev., vol. 39, p. 503,) is one in which tubercular matter appears to have been confined to a small space in the lungs. He examined the patient three years after, when pectoriloquy still existed. Now allowing him full credit for the accuracy of his observations, (and to which indeed I think him fully entitled,) we should remember that such cases occasionally do well without any treatment. I know a young man who, some ten years ago, expectorated a considerable quantity of what, from description, I suppose to have been tubercular matter, in whom pectoriloquy of the right side is very evident, and who is in good health now. Whilst therefore we are disposed to allow due weight to each remedy, we should still be on the watch to see that we do not allow more than is due to some of them. 60 Wherever the deposits of tubercular matter may be, I hold it important that some mode of counter irritation be used at the same time, that we pursue the remedial and hygienic rules already noticed. I will add a few words concerning that form of scrofula most common in this vicinity, I mean Cachexia Africana. During the prevalence of cholera, many negroes who appear- ed strongly predisposed to this disease were restored to a state of good health. This was effected, as I suppose, by the free use of calomel, which was then resorted to as a remedy for cholera. Now 1 believe that mercury must be used with cau- tion in scrofulous diseases; and it certainly was not used with a sparing hand in those days. How is this to be accounted for? Thus: The beneficial action of a remedy does not de- pend upon the amount taken, but upon the effect produced. At that time our diseases required, at least tolerated, the use of ealomel to an extent which would now do incalculable mis- chief. The quantity then used did not generally go beyond the remedial bounds; I say generally, for it is certainly true that even then great mischief was sometimes done. I think I have cured, at least that I have seen get well, divers cases of this disease, by pursuing the treatment advised, not by emetics, not by purgatives, not by tonics, but by what I thought a ra- tional employment of each in its proper place, aided in no small degree by an enforcement of the hygienic regulations. I have always remembered that it was a work of time, and believed that the old adage lthe more haste, the less speed,' was peculiarly applicable. A friend informed me that he had seen two cases cured, as he believed, by diuresis, in one case occasioned by taraxacum, in the other by a large quantity (two ounces) of vinegar of squills taken by mistake. Although diuresis frequently attends the employment of iodine, yet I am disposed to believe that the amendment in these cases was due to the previous judi- cious treatment which my friend had instituted; but the amendment becoming evident soon after an event so marked, there was an apparent fitness in ascribing it to that. 61 A long time ago, I was attending a case of this disease with very little satisfaction to myself, and no apparent advantage to my patient, when from some cause I ceased to attend. The mistress, thereupon, commenced giving a tincture of poke berries. {Phytolacca Decandra.) Soon after this course was adopted, the patient commenced improving. Whether such improvement was the delayed effect of my treatment, in whole or in part, I cannot tell. The remedy, however, is used in scrofulous affections by the same lady with, as she thinks, marked benefit. A physician in one of our southern States, as lam informed, (but I have not learned his name or seen his book,) has writ- ten a book upon this disease, in which he considers walnut leaf tea the remedy. Negrier, of Angiers, some years ago, published a 'number of cases of disease of the lymphatics, with or without ulceration of the integuments, of scrofulous ophthalmia, of affections of the bones and periosteum, &c, in which a decided and very marked benefit was obtained from a course of this simply prepared tea. A handful of the fresh or slightly dried leaves may be added to a pint of boiling water, and of this infusion a small cupful may be taken twice a day. An extract may also be prepared by evaporation, and this Dr. Negrier recommends to be given at the same time either in the form of pills or of a thick syrup. A strong de- coction of the leaves he has used with excellent effect as an application to scrofulous ulcers.' Med. Chirurg. Rev., vol.36, p. 192—From Archives Generales. The reviewer 'feels in- clined to predict that this remedy is one deserving notice, and that it will be found useful in some cases of lymphatic and cutaneous disease.' I am not informed as to the use or not of other means by Dr. Negrier. I cannot, therefore, ex- press any opinion as to the proportion of credit due to the walnut leaves. I most sincerely wish that a remedy, an infal- lible remedy, may be found for this frightful disease; but I must confess that I expect the day to come at no great distance of time, when walnut leaf tea (at least when exclusively trusted to) will take its place by the side of acorn coffee. 62 Having spoken of poke berries and walnut leaves, I may perhaps as well name another remedy, which has been found successful in the cure of scrofula. I mean the prickly ash, (Xanthoxylum Fraxineum.) In West. Jour. Med. and Surg., vol. 4, p. 361, we have the report of three cases cured by this article. In each case a long course of treatment to no ef- fect had preceded. It is directed to be prepared thus: boil a handful of the bark of the stem or root in a new iron vessel; let it stand until the iron has blackened the tea; give thrice daily as much as the stomach will bear without nausea. This shrub resembles little scrubby black locust when divested of leaves, and has a very pungent taste, which speedily imparts a tingling sensation through the nervous system, something like gum guiacum. I am very much disposed to believe that these cases were such as had been treated too long, and were in fact cases of mercurial disease instead of scrofula. Until better informed upon the subject, I shall place them on a foot- ing with a very obstinate case of syphilis, which a medical friend of mine informed me had been effectually cured by May apple root (Podophyllum Peltatum). As a consequence, he had resolved to cure all cases of syphilis in the same way. It was suggested to him that, probably under the use of the May apple his friend had got well of the mercurial disease which had been substituted for the venereal. But he was so firmly persuaded of the virtues of the May-apple, that he put his next syphilitic patient upon it. But his good sense soon taught him the difference between May-apple and mercury. Conclusions.—After such reflections as I have been able to make, I arrive at the following conclusions: 1st. That in a vast majority of instances scrofula owes its existence to inheritance; yet 2d. That there is no absolute necessity that a child having a scrofulous parent shall be scrofulous; on the contrary' 3d. That when one parent is scrofulous and the other not a child which resembles the scrofulous parent will be much 63 more apt to have scrofula than one which resembles the other parent; in fact, that the latter may have a well-grounded hope of escape. 4th. That the liability by inheritance depends upon a gen- eral, not upon a specific law, which is applicable to other dis- eases besides scrofula. 5th. That whilst a child born of scrofulous parents may es- cape, one born of parents not at all scrofulous, may have the disease. 6th. That scrofula depends upon an undue preponderance of the white parts of the blood, and the white tissues in the body. 7th. That in our treatment we should endeavor to restore a due proportion of the red particles to the blood, and of the red tissues to the body. 8th. That to effect this there is no specific; but we must be guided by general principles and rational views, pre- cisely as is necessary to treat successfully any other dis- ease. 9th. That how important soever medicine may be in the management of the disease, hygienic rules are by no moaii3 less so. Note.—In all our quotations from the Medico-Chirurgical Review we have had reference to the American reprint of that work. 6 NLM032772316
