Proving Medicines

Organon Aphorism §113

The only exceptions to this are the narcotic medicines. As they, in their primary action, take away sometimes the sensibility and sensation, sometimes the irritability, it frequently happens that in their secondary action, even from moderate experimental doses on healthy bodies, an increased sensibility (and a greater irritability) is observable.
