The book drew criticism from consumers and practitioners of alternative therapies.The British Journal of General Practice published a review by Jeremy Swayne (former Dean of the Faculty of Homeopathy) that was critical of the book and its argument.
A review by Harriet A. Hall in Quackwatch stated that some negative reviews of the book demonstrated “an appalling poverty of thought”; articulating that since the reasoning behind the author’s conclusions is solid, critics instead deny the methods of science, misrepresent the books’ contents and use ad hominem attacks against the authors.
