Edzard Ernst, MD, PhD
Edzard Ernst, MD, PhD, assumed the position of Professor of Complementary Medicine at the University of Exeter in 1993. A junior doctor in a homeopathic hospital and supporter of homeopathy and “Complementary and Alternative Medicine” (or “CAM”) himself, Ernst has become a vocal critic of modalities not supported by scientific evidence.  He argues that the term, “Complementary and Alternative Medicine” should not be used as an umbrella term and that a clear distinction should be made between these practices. In his 2008 book, Healing, Hype or Harm? A Critical Analysis of Complementary or Alternative Medicine, he looks at conventional medicine versus that of the alternative, stating “The worst medical doctor can cure diseases and save lives; the best alternative healer can only offer false hopes.” Dr. Ernst who with Simon Singh co-authored the best seller Trick or Treatment? Alternative Medicine on Trial retired from the University of Exeter this past summer, after producing more than 1,000 research papers. He continues to teach at the University on a part-time basis.
