Sanskrit Samhita Siddhanta
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.
In order to explain the functional complexity of human body, Ayurveda has propounded a few basic doctrines. 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.
All ayurvedic studies conducted on herbal and holistic medicine, in ancient India, were followed from the fountainhead of the two principle Ayurvedic schools. The School of Physicians (Atreya) and the School of Surgeons (Dhanvantari) epitomized the eight main areas of Ayurvedic studies and specialization, during ancient times.
The details of these eight branches of this natural alternative medicine are present in the three ancient Ayurvedic texts - Charaka Samhita, Susruta Samhita and Astanga Hridaya.
