Expert herbalist Matthew Wood takes the guesswork out of the application of medicinal plants in this first comprehensive herbal repertory, which provides an invaluable cross-reference of constitutional types, energetic categories, and specific symptoms that leads the herbalist to a limited number of possible herbs for a specific condition. Unlike many references in which medicinal plants are defined simply by condition or disease name, this book provides a basic plan for analyzing each case in a holistic fashion. The energetic (hot, cold, damp, dry, tense, relaxed) or action (sedative, stimulant, alternative, nutritive, relaxant, astringent, etc.) is cross-referenced with the organic, system, or function where the problem resides and specific symptoms known to indicate that specific herb or class of herbs. Drawing on his 35 years' experience as a practicing herbalist who has treated tens of thousands of clients, Wood incorporates knowledge from ancient Greek and traditional Native American medicine, the traditions of nineteenth-century botanical medicine, homeopathy, and modern biomedical research.
