THE FOUR MEDICAL TANTRASThe essence of TTM theory and practice is contained within the Four Medical Tantras ( གྱུད་བཞི།
Gyud Zhi), considered the root text of Tibetan Medicine:
- Root Tantra an essential map of the entire medical system, including the basis of health and disease.
- Explanatory Tantra an exposition of anatomy, physiology, and embryology, as well as diagnosis and treatment.
- Oral Transmission Tantra a detailed presentation of diseases from eight major branches of pathology, with treatments.
- Final Tantra instruction in practical and clinical medicine.
The Four Medical Tantras were composed by
Yuthok Yonten Gonpo the Elder (729-854 AD) and revised by
Yuthok Yonten Gonpo the Younger (1126-1202 AD), known as the 'Father of Tibetan Medicine'.
