Organon Aphorism §27

The curative power of medicines, therefore, depends on their symptoms, similar to the disease but superior to it in strength (§ 12 – 26), so that each individual case of disease is most surely, radically, rapidly and permanently annihilated and removed only by a medicine capable of producing (in the human system) in the most similar and complete manner the totality of its symptoms, which at the same time are stronger than the disease.
