Book excerpt: "Since antiquity, humans have used botanicals to treat various conditions affecting their organ systems. This book is built around explaining which plants may be used for major ailments affecting the various systems. The increasing availability of botanicals on the market, intended to be used as dietary supplements for health, has been fueled by the public's demand for a more natural approach to healthcare. Unfortunately, much of the information fed to the public on alternatives is based on anecdotal evidence (case studies), the advice of friends, or media features that often do not stand up to standards for scientific evidence. In this book, Al-Achi explains current research and science that exists or remains lacking-for the various botanicals as healthcare products. He also details the potential misuse and the dangers of some herbal formulas. Photographs of 62 medicinal plants are included."--BOOK JACKET.
