Shelton (physics, Santa Fe Preparatory School) analyzes the history, the remedies, the theories, and the effectiveness of homeopathy. He offers evidence against the two chief principles of homeopathic practice ("the law of similars" and "potentization") and suggest alternative explanations as to why most people who visit homeopaths get better. He also pursues the question of why so many people attribute their healing to the homeopathic remedies rather than other factors. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
