Prince Charles has entertained a long-standing love affair with alternative medicine. This book describes his passion as it developed during the last 40 years. The Prince’s beliefs, opinions, and ambitions are critically assessed against the background of the scientific evidence. In most instances, the contrast could not be starker. Thus, Charles‘ tenacious promotion of unproven, disproven, and occasionally harmful alternative therapies turns out to be little more than the pipe dream of a self-declared enemy of the Enlightenment. The book portrays our future king, reviews the evidence on alternative medicine, and inspires critical thinking.
