This book is based on the medicinal plants of Ladakh used in the traditional system of medicine in the Northern part of India, which consists of the Leh and Kargil districts. The medicinal plants described in this book are based on the survey work conducted with the financial support of the Ministry of AYUSH Government of India. Interestingly, there are several species described in this book that are for the first time identified by the author. Although there are many floras used as medicinal plants including some regional floras of India including Indian Medicinal Plants, the flora of indigenous plants of India and some Medicinal plants of Jammu and Kashmir, the present book mainly focuses on the medicinal plants of the Ladakh region used in their traditional medicinal system called Sowa Rigpa or Amchi.
