Drug proving in Homeopathy
Drugs
Drug Proving in Homeopathy is unique since it involves study of effects of drugs in Human beings and not animals as in other systems of medicines. Importance is given to Subjective symptoms than signs (which are objective). Since a human can express his feelings and can speak, accurate study of effects of drugs on the Mind (mental level) is noted. Volunteers who are healthy individuals are used to prove various drugs. Proving of one drug may take up to several weeks since the prover has to maintain a diary and note down his symptoms on a day to day basis. The Physician is considered the best prover since he actually knows what is going on physiologically and psychologically. This drug is proved on individuals with varied constitutions to form an exact constitution of the individual.
