COMMON NAME, Lactic acid.
ORIGIN.--Lactic acid is obtained from sour milk, resulting from the
fermentation of the sugar of milk under the influence of casein.
PREPARATION _for Homoeopathic Use_.--One part by weight of pure lactic
acid is dissolved in 99 parts by weight of alcohol.
(A very complete proving of this remedy will be found in
Allen's _Encyclopaedia of Pure Materia Medica_, but little
use seems to have been made of it, though the following
by Dr. Tybel-Aschersleben, _Allgemeine Hom. Zeitung_,
March 13, 1890, seems to show that it is very efficient
in certain forms of rheumatism.)
We are by no means rich in remedies against arthritic rheumatism, and
those which we do use lack the reputation of being reliable. A new and a
valuable remedy will therefore be a welcome addition to this list. I say
reliable, inasmuch as this remedy is truly homoeopathically indicated
for, according to Foster, of Leitz, Niemeyer's Pathology, 10th edition,
2d vol., pp. 561: "_Lactic acid in large doses and used for a long time
will produce symptoms entirely analogous to arthritic rheumatism_." We
also find mention elsewhere that the use of lactic acid occasioned
rheumatic pains in the thigh.
