Now new scientific insights confirm that natural healers have simply been practicing an entirely valid and very sensible principle called contextual healing. In this informative, enjoyable, and easy-to-understand book, Dr. Dean Black explains the principles of contextual healing, describes the science behind them, and reveals the critical and potentially transforming challenges they present to medicine, to our lawmakers, and to us.
