Book excerpt: The Oxford Handbook of Complementary Medicine presents evidence-based information on CAM in an easily accessible form, thereby enabling hospital doctors, GPs, nurses, medical students and other healthcare professionals to competently advise patients about CAM treatments. The book covers definitions, cost, safety, regulation, legal and ethical questions and a range of practical issues, diagnostic techniques, and risk-benefit assessments of CAM modalities. The main part of the book is organised by condition, outlining for each the CAM treatments available, ranked according to level of evidence of effectiveness, followed by a concise clinical bottom line assessing risks and benefits, also in relation to conventional treatment. The information is presented in a concise, matter-of-fact fashion, avoiding the obscure jargon sometimes used in CAM. Many issues surrounding CAM remain controversial and this handbook discusses them openly and critically.
