Proving Medicines

Organon Aphorism §120

Therefore medicines, on which depend man’s life and death, disease and health, must be thoroughly and most carefully distinguished from one another, and for this purpose tested by careful, pure experiments on the healthy body for the purpose of ascertaining their powers and real effects, in order to obtain an accurate knowledge of them, and to enable us to avoid any mistake in their employment in diseases, for it is only by correct selection of them that the greatest of all earthly blessings, the health of the body and of the mind, can be rapidly and permanently restored.
