Characteristics.-Lactic acid “was discovered by Scheele in sour milk, the result of the spontaneous fermentation of sugar of milk, under the influence of casein. It is also met with in many vegetable products which have turned sour” (Hering). Reisig introduced it into homoeopathy. It has been proved in both the lower and higher attenuations, but many valuable observations have been made on patients taking substantial doses for diabetes (C. D. P.). In these cases the symptoms of rheumatic fever were directly traced to the acid. Pain, swelling, and stiffness and tenderness of joints < by motion (as with Bry., which antidotes Lact. ac.), and flying pains about limbs. One prover had pain along the right sciatic nerve. The well-known effects of milk that has soured on the stomach and remained undigested were produced-nausea, vomiting, burning and sense of weight; and these have all proved useful indications in the homoeopathic use of the drug. Diabetes is the affection for which it has been most given in old-school practice; but it has also proved of great power in this affection in the homoeopathic attenuations. Nash regards the concomitance of rheumatic pains as the chief guiding symptom here. (In Med. Adv., xxi. 508 he records a case of diabetes, with rheumatic fever supervening, cured with Lact. ac. 200.) But nausea is no less a guide: Constant nausea; nausea on awaking before rising; > by eating. This may occur in diabetes; or it may occur in pregnancy. It is also an indication when occurring in rheumatism. There is > by eructations; and < by smoking. Smoking < eructations. Copious foot-sweat is a feature of Lact. ac., but it is not offensive. It is suited to anaemic, pale women. Large doses disagreed with melancholic, choleric constitution, dark hair and eyes.
