The Unani system of Medicines has its origin in Greece and was introduced into India in the thirteetnth century by Arab scholars. This system attempts to cure diseases by administration of drugs made from Herbs and Minerals. Most of the Unani Drugs have sugar-base as that makes it easy to take the medicine.
Unani Medicine established that disease was a natural process and that symptoms were the reactions of the body to the disease. It believes in the humoral theory which presupposes the presence of 4 humours -Dam (blood), Balgham (phlegm), Safra( Yellow bile) and Sauda (black bile) in the body. Each humour has its own temperament - blood is hot and moist, phlegm cold and moist, yellow bile hot and dry and black bile cold and dry. According to Unani, if the four main humours and the four primary qualities were all in a state of mutual equilibrium, one is considered healthy.
The diagnosis of diseases in Unani system of medicine is through examination of pulse, urine and stool. This system observes the influence of surroundings and ecological conditions such as air, food, drinks, body movement and repose, psychic movement and repose, sleep and wakefulness and excretion and retention on the state of health. This influence causes a dominance of one of the four humours in every human body. Unani believes that it is this dominance which gives a man his individual habit and complexion i.e his temperament.
