This popular, evidence-based overview of complementary and alternative medicine (CAM) emphasizes clinical research, analyzes the effectiveness of each therapy, and presents practical information on how these therapies can be used to treat health conditions and diseases. It not only acquaints the reader with information about CAM, but provides evidence for the effectiveness of various therapies used to treat medical conditions ranging from allergies to psychiatric conditions--in all populations relevant to CAM including children, women, and the elderly. Summary tables embedded throughout highlight clinical data, statistics, and major research findings. More thorough documentation in this edition is achieved through new tables and added commentary on the quality of studies, making research findings more relevant and useful.
