The Ayurvedic
tradition has numerous innovators and teachers. Three of the most important are
Dhanvantari of Benares (c. 1500 BCE), Nagarjuna (c. 500 AD), Vagbhatta of Sind (c. 342
BCE).
Dhanvantari of Benares is considered to be the reincarnation of Vishnu
and the guiding sage of Ayurveda. He established Ayurveda as a specific healing art and is
the spiritual originator of the Dhanvantari School of surgeons.
Nagarjuna, a famous Mahayana Buddhist sage, wrote a commentary on the
Sushruta Samhita.
Vagbhatta of Sind wrote the Ashtanga Hridaya Samhita, a commentary on
the Charaka and Sushruta Samhitas with a combination of works by other prominent Ayurvedic
authors. He is responsible for introduction of new Herbs and surgical techniques into the
previous orthodox Ayurvedic schools.
