How Homeopathy Cures

Organon Aphorism §45

No! Two diseases, differing, it is true, in kind but very similar in their phenomena and effects and in the sufferings and symptoms they severally produce, invariably annihilate one another whenever they meet together in the organism; the stronger disease namely, annihilates the weaker, and that for this simple reason, because the stronger morbific power when it invades the system, by reason of its similarity of action involves precisely the same part of the organism that were previously affected by the weaker morbid irritation, which, consequently, can no longer act on these parts, but is extinguished, or (in other words), the new similar but stronger morbific potency controls the feelings of the patient and hence the life principle on account of its peculiarity, can no longer feel the weaker similar which becomes extinguished – exists no longer – for it was never anything material, but a dynamic – spirit-like – (conceptual) affection. The life principle henceforth is affected only and this but temporarily by the new, similar but stronger morbific potency.
