We all know someone who has had a seemingly miraculous cure from an alternative form of medicine: a friend whose chronic back pain vanished after sessions with an acupuncturist or chiropractor; a relative with digestive issues who recovered with herbal remedies; a colleague whose autoimmune disorder went into sudden inexplicable remission thanks to an energy healer or healing retreat. The tales are far too common to be complete fabrications, yet too anecdotal and outside the medical mainstream to be taken seriously scientifically. How do we explain them and the growing popularity of alternative medicine more generally? In , author and journalist Melanie Warner takes us on a vivid, important journey through the world of alternative medicine. Visiting prestigious research clinics and ordinary people’s homes, she investigates the scientific underpinning for the purportedly magical results of these practices and reveals not only the medical power of beliefs and placebo effects, but also the range, limits, and uses of the surprising system of self-healing that resides inside us. Equal parts helpful, illuminating, and compelling, is a “well-written survey of alternative medicine...fair-minded, thorough, and focused on verifiable scientific research” ( , starred review). Warner’s enlightening, engaging deep dive into the world of alternative medicine and the surprising science that explains why it may work is an essential read.
