The Myrica belongs to a group of remedies of which Hepar 
sulphur is the typical member. It has many points of analogy 
with other medicines belonging to that group, while it holds 
relationship to members of others. A close study of its symp- 
toms will show these points of resemblance. 
The Bayberry has been in common use in the practice of the 
people, and the so-called “ Botanic ” physicians, ever since the 
settlement of New England. The Eclectic school hold it in 
high estimation in many diseases. 
It remained for the Homoeopathic School to investigate its 
powers and uses in a rational manner. The first notice of this 
medicine in our literature was in the second edition of “New 
Remedies,” where its botanical description and medical history 
was given, and two extended provings by Dr. L. Walker. 
The next public mention of the Myrica was made in the 
second volume of “ Publications of the Massachusetts Homoeo- 
pathic Medical Society.” This consisted of a “Report of the 
Committee on Materia Medica,” made to that Society in 1864. 
This report consists of provings made by Dr. H. L. Chase, Dr. 
Charles Cullis, Dr. C. Wesselhceeft, Dr. F, H. Krebs, Dr. J. 
E. Linnell, and two women. Some of these provings were made 
with the mother tincture, others with finely-pulverized bark. 
Eight provings have been made of the Myrica, The following 6 
pathogenesis of myrica cerifera. 
pathogenesis is composed of the symptoms thus obtained, also 
from a few fragmentary provings, and accidental symptoms, 
observed by Dr. H. P. Hale and Mr. Chapman (Chemist). All 
the symptoms recorded appear to be reliable and trustworthy. 
The curative symptoms were obtained from reliable persons, 
and from the results of my own observation and use of the 
remedy. 
This pathogenesis, although not as complete as could be 
desired, is full enough and sufficiently suggestive to be the 
basis of its use in the selection of the remedy. That it will 
prove a valuable medicine, we do not doubt, if it* is carefully 
selected and used in proper doses. The cures made with the 
Myrica have, up to this time, been made with the crude drug 
and the lower attenuations ; no experience of its use in the 
higher potencies has yet come under my notice. 
Without attempting to theorize in relation to its special 
affinities, the Myrica appears to me to act principally upon the 
mucous membranes. This is a general action, and seems to 
extend to its remotest and minutest ramifications. I believe 
that nearly all its symptoms arise directly or indirectly from 
this action. 
Explanation of Signs.—A symptom in italic indicates its 
apparent importance, or prominence in the provings. The 
words “ in” “when,” u with,” 11 it,"1 etc,, italicised, indicate the 
special relation of two or more symptoms. The sign indicates 
a simple pathogenetic symptom. The sign “ * ” indicates that 
the symptom has been verified by a cure. The letters (v) or 
(vvv) indicate that the symptom has been verified by one or 
more provers. The sign “ ° ” is prefixed to a curative symptom 
or group of symptoms not found in the pathogenesis. The 
letter (t) indicates that the cure was made by the topical appli- 
cation. The pathogenetic symptoms are all numbered after the 
usual plan.

* The icteric symptoms of Myrica are undoubted. Dr. Walker proved the drug under my 
own observation, liy reference to the two provings made by him, it will be seen that during 
the first proving he had “ drowsiness, with heavy frontal morning headache, yellowness of the 
eyes, scantiness of urine, and light-colored faeces,”—all the premonitory symptoms of jaundice. 
At this point the medicine was suspended, and the above symptoms disappeared. At the next 
proving the same symptoms recurred, but this time were kept up by the action of the drug until 
complete jaundice obtained. This jaundice, I believe, was owing to suspended secretion, and 
not to obstruction. Had the latter condition been the cause of the jaundice, critical discharges 
of black, tarry matters would have been noticed,whereas, in this case, the fasces, undei the action 
of Digitalis, gradually resumed a healthy color and appearance, and the same change occurred 
in the condition of the urine. Jaundice appears to be a secondary effect of Myrica ; conse- 
quently when used as a curative agent in that disease, the lower attenuations will be best indi- 
cated. II. PATHOGENESIS OF MYRICA CERIFERA.
