I almost bought a book about EFT before, but I read the Wikipedia about it first.
Wiki wrote: A 2003 controlled study of 119 university students, with self-reported specific phobias, found that EFT diminished fear in participants but that the effects were due to conventional therapeutic techniques and distraction rather than the EFT theory proposed by the practitioners.
There is no evidence that acupuncture points, meridians or the other concepts of traditional Chinese medicine exist. An article on EFT published in Skeptical Inquirer described the evidence supporting the theory as anecdotal and because the number of points at which the body’s meridians can allegedly be manipulated are so numerous, it is impossible to falsify the theory of EFT, thus rendering it pseudoscientific. A 2009 review found that the “small successes seen in [emotional freedom technique and the Tapas acupressure technique] therapies are potentially attributable to well-known cognitive and behavioral techniques that are included with the energy manipulation. Psychologists and researchers should be wary of using such techniques, and make efforts to inform the public about the ill effects of therapies that advertise miraculous claims.”
Like I said before, if you have an overactive stress response, you’re never going to recover from your problems. The physiology of stress and its devastating effects are well documented, and anything that helps you control it is going to benefit your health. If that happens to be EFT, then it’s worth pursuing.
People have got relief from believing much crazier things (try looking up John Sarno), but what these therapies all have in common is the ability to help you relax and stop worrying, to free you of the emotional burden of your health problems. In some cases, that’s all it takes to recover.
