Comments	The Four Tantras contain 156 chapters and are divided into four books. The current version is based on the 12^th century edition, compiled by the famous physician Yuthog Yonten Gonpo (1112-1203), and is the most important text in Tibetan medicine still today. The debate whether it is the translation of an Indian text, or a Tibetan composition is ongoing, although most scholars agree that it must be indigenously Tibetan, but has been heavily influenced by Indian, Chinese, Greek and other medical traditions. The chapters explicate the eight branches of Tibetan medicine: the body (including physiology, anatomy, embryology, pharmacology), paediatrics, gynaecology, disorders caused by spirits, wounds inflicted by weapons, toxicology, geriatrics, and fertility.
