Organon §66
A minute homeopathic dose produces a perceptible initial action, but the life force's counter-action is inconspicuous.
In the healthy body, with the impinging action of quite small homeopathic doses of tunement-altering potences, a conspicuous opposed after-action will not be perceived. This is understandable. To be sure, all of these potences, in small doses, bring forth an initial action that is perceptible with due attention, but the living organism produces, in return, only as much counter-action (after-action) as is required for the restoration of the normal state.
