Ancient Tibetan Medicine: From Bön to Buddhism
Medicine has been believed to be an integral part of Tibetan culture as early as the inception of the Bön tradition, centuries before the introduction of Buddhism to Tibet. According to several Bön texts, the founder of the Bön religion, Shenrab Miwoche, allegedly included shamanistic and naturopathic healing practices in his teachings. These customs were then reformed and solidified centuries later during the reign of Songsten Gampo, who in addition to being credited with bringing Buddhism to Tibet, supposedly invited Chinese, Indian, Nepalese and Iranian doctors to Tibet to share their knowledge of medical practices.
