Today’s evolving interest in ecology and the preservation of nature has led us to reconsider the importance of the plant world as it relates to our health. Plants have always occupied a prominent part in the healing arts throughout history and to our present day. The contemporary environmental scientist and author, G.

Of course we don’t sell willow bark over the counter now -we simply synthesize the aspirin tablet from it. This book is organized by major therapeutic category. It brings together the achievements of three major disciplines to help us understand and appreciate the importance of some select medicinal plants.
