Compiled based on the renowned work of Dri-Med Shel-Phreng on Tibetan medicinal herbs, written by Deu-Mar Geshe Tenzin Phuntsok. Book contents cover the tastes, inherent qualities and digestive principles of the medicinal plants in accordance with the Four Medical Tantras, supplemented with features of modern methodology on the identification of herbs, the time and season for harvesting, and places where these may be found. The herb processing techniques for the preparation of various medicines before their inherent qualities fade. Also, the seven principles of preparing medicines are explained.

This book is a result of Doctor Dawa’s tireless research carried out in the Himalayan regions such as in Lahaul, Spiti, Rothang, Nyung-ti, Solokhumbu, and the valley of the Flowers in the Garhwal Hills as well in the southern hills of Bylakuppe, Mysore and others. It is hoped that this book will become and indispensable manual for those who practice and study Tibetan Medicine.
