Ayurveda is one of the World's oldest and most comprehensive systems of natural medicine, and is particularly useful for addressing the chronic conditions Western medicine finds difficult to treat. This authoritative book provides a comprehensive introduction to Ayurvedic medicine for the practitioner or student. The authors describe the foundations and principles of Maharishi Ayurveda in detail, and drawing on the latest scientific research into its efficacy, show what it can offer clinical medicine in the West. Topics covered include pathogenesis and diagnosis, diet and digestion, toxic build-up, purification therapies, the effects of the emotions and thinking on health, and the practical applications of Transcendental Meditation. This updated and expanded second edition describes specific Ayurvedic treatments for a range of common medical conditions, and also contains information on more general Vedic approaches to health and wellbeing. This book will provide complementary and alternative health practitioners with a solid base on which to build their understanding of Maharishi Ayurveda, and will also be of interest to mainstream health professionals wishing to learn more about the efficacy of this ancient healthcare system.
