Nature was the earliest source of vital human medicines and has provided a continuous source of raw materials used for treating human and animal ailments.This book covers 372 plant species with their ethnobotanical uses. Vital information relating to their vernacular names, habit, habitat, identifying characters, flowering, fruiting, distribution and folk uses for human has been documented. The distinctive feature of this book is the use of plants for ethnoveterinary purposes. Most of the medicinal plants are either used green or as dried powder or after being extracted in water or oil or as decoctions and infusions. The complex chemical names of active principles have been avoided in view of the scope of this book. It is hoped that this book will benefit to academicians, research scholars, conservationists, school and college students and most importantly, the general public who are plant lovers. I take the responsibility of any errors that have inadvertently crept in this publication and I should gratefully appreciate if they are kindly brought to my notice. Any valuable suggestion for the enrichment of the book in future is welcome from its readers.
