Organon §27

A disease is most surely, thoroughly, rapidly and permanently removed by a medicine that can engender a totality of symptoms most similar to the disease, but stronger.

The curative capacity of medicines therefore rests upon their symptoms being similar to the disease but with power that outweighs it (§22-§26). Each single case of disease is most surely, thoroughly, rapidly and permanently annihilated and lifted only by a medicine that can engender, in the human condition, a totality of symptoms that is the most complete and the most similar to the case of disease but that, at the same time, exceeds the disease in strength.
