Trick or Treatment
Cover of first edition
|Author||Simon Singh, Edzard Ernst|
Trick or Treatment? Alternative Medicine on Trial (North American title: Trick or Treatment: The Undeniable Facts about Alternative Medicine) is a 2008 book about alternative medicine by Simon Singh and Edzard Ernst. Singh is a physicist and the writer of several popular science books. Ernst is a professor of complementary medicine.
The book evaluates the scientific evidence for acupuncture, homeopathy, herbal medicine, and chiropractic, and briefly covers 36 other treatments. It finds that the scientific evidence for these alternative treatments is generally lacking. Homeopathy is concluded to be completely ineffective: "It's nothing but a placebo, despite what homeopaths say".
Although Trick or Treatment presents evidence that acupuncture, chiropractic and herbal remedies have limited efficacy for certain ailments, the authors conclude that the dangers of these treatments outweigh any potential benefits. Such potential risks outlined by the authors are contamination or unexpected interactions between components in the case of herbal medicine, risk of infection in the case of acupuncture and the potential for chiropractic manipulation of the neck to cause delayed stroke.
The book is very critical of Prince Charles' advocacy of alternative medicine and the actions of his now-defunct Foundation for Integrated Health. Trick or Treatment is dedicated, in an ironic fashion, to the Prince.
The book contains six chapters:
How do you determine the truth?
- This chapter describes the methods and history of clinical trials, such as the trial to determine a proper treatment for scurvy by James Lind and the story of Florence Nightingale.
The truth about acupuncture
- This chapter discusses the evidence surrounding acupuncture, a form of alternative medicine in which acupuncturists place needles in the body for the purpose of blocking Ch'i meridians throughout the body, thus encouraging full health. The authors examine the recent history of acupuncture and several various trials of the technique. The authors conclude that acupuncture is essentially a placebo.
The truth about homeopathy
- This chapter discusses the evidence surrounding homeopathy, an alternative medicine technique which consists of finding a substance (which causes symptoms similar to the condition needing to be treated in a healthy person), then diluting that substance to an extreme degree. The chapter examines the history of homeopathy and reviews various trials regarding the technique, especially the trial done by Jacques Benveniste, a French researcher. The authors conclude that homeopathy is a placebo.
The truth about chiropractic therapy
- This chapter discusses the evidence surrounding chiropractic, an alternative medicine technique which aims to cure illness by manipulating the spine, based on the theory that almost all conditions and diseases are caused by misaligned vertebrae in the spine block the body's vital force. The history of chiropractic, as well as several of the trials on chiropractic are described. The authors conclude that there is no evidence to support most of chiropractic's claims. However, the authors state that chiropractic might be beneficial in certain limited situations concerning back pain. As well, the authors find that chiropractic can be very dangerous, especially when it comes to the manipulation of the neck, and state that patients should "try conventional treatments before turning to a chiropractor for back pain."
The truth about herbal medicine
- This chapter discusses the evidence surrounding herbal medicine, such as the use of St. John's Wort and Aloe vera. The authors conclude that several herbal medicines can be effective to treat illness, while others, such as billberry, chamomile, and ginseng, are ineffective.
Does the truth matter?
- This chapter discusses the state of alternative medicine in society, focusing on Prince Charles's endorsements of alternative medicine.
The book received generally good reviews. The New England Journal of Medicine's review said this about the authors: "Simon Singh is a physicist and science journalist, and his coauthor, Edzard Ernst, is a physician and professor of complementary medicine. Ernst is one of the best qualified people to summarize the evidence on this topic." The Daily Telegraph found the book to be "a clearly written, scrupulously scientific examination of the health claims of key areas of alternative medicine: acupuncture, homeopathy, chiropractic therapy and herbal medicine. The results are stark. In no case, apart from in some limited ways in herbal medicine, do any of these 'therapies’ work. On the contrary, they can be life-threatening." The journal Nature tempered a generally positive review with a concern that the authors' sense of certainty "mirrors that of the proponents of alternative therapies, leaving each position as entrenched as ever."
Trick or Treatment 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 on Quackwatch stated that some negative reviews of Trick or Treatment 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 book's contents and use ad hominem attacks against the authors.
Subsequent libel case and freedom of speech
Singh was sued for libel by the British Chiropractic Association for comments he wrote in a column in The Guardian about the book. In 2010, after 2 years, the BCA dropped the case after the court of the appeal found that Singh was expressing opinion, rather than stating facts. The presiding judges commented that "this litigation has almost certainly had a chilling effect on public debate which might otherwise have assisted potential patients to make informed choices about the possible use of chiropractic".
