In this companion volume to The Earthwise Herbal: A Complete Guide to Old World Medicinal Plants Matthew Wood an expert herbalist who has used medicinal herbs with tens of thousands of patients over a twenty-five-year career provides detailed descriptions of New World (North American) herbs and their uses. Organized as a materia medica (names and descriptions of herbs/plants are listed alphabetically) the book explains the use of the whole plant (not just \ active ingredients\ ) in the treatment of the whole person and describes symptoms and conditions that the plants have been successful in treating--from digestive ailments headaches and high blood pressure to asthma skin rashes and allergies to name a few. Wood who has systematically studied ancient and traditional herbal literature takes a historical view and presents information in a thoughtful engaging nontechnical style. In addition he provides remarkable case studies as well as insight into the \ logic\ of each plant--its current and past usage pharmacological constituents and other elements that together produce a comprehensive portrait of each herb.
