How Homeopathy Cures

Organon Aphorism §66

An obvious antagonistic secondary action, however, is, as may readily be conceived, not to be noticed from the action of quite minute homoeopathic doses of the deranging agents on the healthy body. A small dose of every one of them certainly produces a primary action that is perceptible to a sufficiently attentive observer; but the living organism employs against it only so much reaction (secondary action) as is necessary for the restoration of the normal condition.

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