This means the employment of morbid products of a disease for the cure of the same disease [Aequalia aequalibus]. It is of very ancient date, and of late has received renewed attention through the researches of Pasteur, Koch, and others; it necessitates the attenuation of the virus, in order to be used medicinally; it was taught as early as 400 years b. c. by Xenocrates; it was introduced into Homoeopathy by Dr. Lux in 1823, and in part adopted by Dr. Hering. Lux taught that the toxins formed in the body, properly attenuated, are capable of curing the very diseases that give rise to them - that is, every disease is supposed to have within itself its own antidote.

In 1830 Hering proposed as a remedy for hydrophobia the saliva of a rabid dog, properly attenuated; the very teaching and practice of Pasteur. He also proposed Phthisine as a remedy for tuberculosis, and forty years later it, too, received popular and scientific endorsement by Koch and others. As early as 1834, Dr. Stapf, one of the greatest of the early homoeopath-ists, who looked upon the subject dispassionately, says: "I do not doubt that the discovery of the curative action of morbid matters, in diseases that produced them, to be one of the most important discoveries that has been made since the beginning of our school".

Nosodes is the homoeopathic designation for such morbid products, which are animal alkaloids [ptomaines], produced by the decomposition of animal substances. At first ptomaines were restricted to alkaloids produced by cadaveric decomposition, hence the name (ptomaine, belonging to a dead body), but now they also include alkaloids of animal origin formed during life as a result of chemical changes within the organism. These alkaloids have assumed great importance, by reason of their relation to the causation of disease, and it is probable that most pathogenic bacteria produce their effects through their specific alkaloids. The homoeopathic nosodes are these specific alkaloids attenuated according to homoeopathic methods and administered according to the Law of Similars. To obtain a permanent place in the Materia Medica, as Psorinum, the principal of the nosodes, has already achieved, and not be the victim of a passing therapeutic fad, as is the fate of most old-school therapeutic novelties, they must be proved on the healthy, and the pathogenetic effects thus obtained be the only guide for their therapeutic application. To apply them empirically for similar diseases corresponding to their origin as is done by the old-school with tuberculin, antitoxin is disastrous and non-homoeopathic.
