Ayurveda represents the ancient Indian art of healing. In it, the human body is not considered just as a mass of organs, systems and tissues; but the complex mechanism' of myriad functions taking place, both at physical and mental level, are evaluated and described. In existence for thousands of years now, the basic principle of Ayurveda has managed to remain the same. The human body is more complex than any other form of life as on date. Purusha - the human body is the aggregate of 25 elements, together with Atma - the spirit or soul.

These doctrines visualize the functional units of the body to be formed by three Dosha (humours), seven Dhatu (tissues) and Mala (metabolic end products) which are in equilibrium.
