This book is intended to be a popular guide on medicinal plants - their identification, classification, nomenclature, and their uses. Designed primarily for Indian scholars, the book focuses on the medicinal flora found in the Raigad district of Maharashtra. It combines the traditional uses and descriptions of medicinal plant species that are used regularly by the local inhabitants and the tribal communities. Raigad district with its varied physiographic, climatic and edaphic conditions reflects a wide assortment of rich medicinal plants. In the present book, the authors have attempted to compile traditional knowledge surrounding medicinal plants in a classical manner. A layperson rarely uses the botanical names of plants, instead s/he uses the popular or vernacular names. One of the purposes of this book is to popularize and supply standard, meaningful and common or vernacular names for the medicinal plants. Therefore, this book is accessible to readers from diverse disciplines. The authors have recorded their original observations made during the extensive field work in the area from 2009 to 2014. This contribution will be a useful resource for postgraduate and doctoral scholars of Botany, Pharmacy, Bio-medicines etc. Additionally, personnel engaged in plant-based industries will also find the information in this book very valuable.
