Ayurveda is the science of healing human body. It is one of the oldest recording of medical science dating thousands of years ago. It is mentioned in Atharvaveda, believed to be made around 1000-1200 B.C., so Ayurveda pre- dates that. There were 3 mighty Vaidyas (Doctors) who reconstructed the old scriptures during the course of different eras, these were Charaka, Sushruta & Vagabhat. The three books are available even today and students learn from that book.
