Proving Medicines

Organon Aphorism §136

Although, as has been said, a medicine, on being proved on healthy subjects, cannot develop in one person all the alterations of health it is capable of causing, but can only do this when given to many different individuals, varying in their corporeal and mental constitution, yet the tendency to excite all these symptoms in every human being exists in it (§ 117), according to an eternal and immutable law of nature, by virtue of which all its effects, even those that are but rarely developed in the healthy person, are brought into operation in the case of every individual if administered to him when he is in a morbid state presenting similar symptoms; it then, even in the smallest dose, being homoeopathically selected, silently produces in the patient an artificial state closely resembling the natural disease, which rapidly and permanently (homoeopathically) frees and cures him of his original malady.

Study notes for this aphorism are not published yet. They appear here once a homeopath has reviewed them.
