Homoeopathy is a system of medicine based on the principle like cures like. While mention of this principle is found in the writings of Hippocrates (400BC) and even earlier in those of the ancient Indian poet Kalidas (approx. 10th Century BC) it was a German physician Dr. Samuel Hahnemann Hahnemann1who in 1790 founded a system of therapeutics based upon it. Hahnemann became interested in the curative powers of the medicines, and in one of the text books of his time he read that cinchona bark (from which quinine is extracted) cured malarial type fevers as it is bitter. He thought that the best way to determine the action of cinchona was to see what effect it had on the body. Thus he took some of the substance himself, and much to his surprise he developed fever, chills and other symptoms resembling those of malaria.This result made him see that the reason why cinchona is effective in cases of malarial type fever is perhaps because it is capable of producing a condition very similar to malaria. He repeated this experiment and performed several others with other medicinal substances on himself and on volunteers from amongst his family, friends and students, and each time obtained the same result.
