Origin and Development
Siddha
Siddha System is one of the ancient traditional systems of medicine in India. Siddhars the spiritual scientists of Tamil land are the founding fathers of this scientific system.

According to Siddha System the human body is the replica of the universe so are the food and drugs irrespective of their origin. Siddha system believes that all objects in the universe including human body are composed of five basic primordial elements, namely earth, water, fire, air and space. The human body is a conglomeration of three humors and seven physical components. The Food is considered to be basic building material of human body, which gets processed into humors, tissues and wastes. The equilibrium of humors, body tissues and waste products is considered as health and its disturbance or imbalance leads to disease or pathologic state.
This system also deals with the concept of immortality and salvation in this life. The exponents of this system consider that achievement of this state is possible by regulated diet, medicine and processing of mind by yogic or spiritual exercises like meditation and yoga.
