Choosing the Remedy

Organon Aphorism §157

But though it is certain that a homoeopathically selected remedy does, by reason of its appropriateness and the minuteness of the dose, gently remove and annihilate the acute disease analogous to it, without manifesting its other unhomoeopathic symptoms, that is to say, without the production of new, serious disturbances, yet it usually, immediately after ingestion – for the first hour, or for a few hours – causes a kind of slight aggravation when the dose has not been sufficiently small and (where the dose has been somewhat too large, however, for a considerable number of hours), which has so much resemblance to the original disease that it seems to the patient to be an aggravation of his own disease. But it is, in reality, nothing more than an extremely similar medicinal disease, somewhat exceeding in strength the original affection.
