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.
