The proving of medicines is a distinctive feature of Homoeopathy and a logical necessity for applying the law of cure, for in order to meet morbid states with drugs corresponding to them, we must know, and therefore ascertain, what morbid states the different medicinal substances produce. It consists in the systematic testing of a drug on the healthy human body, in order to ascertain the changes which it is capable of producing in the functions and organs.
