It seems extraordinary that with the NHS experiencing major funding problems and people being turned down for treatments on the grounds of cost that we're paying for people to have this kind of therapy.
If you read the theory behind it it's obviously bogus and the results of all the trials that have been done have consistently shown it to be no better than placebo.
The only way to justify it that I can see is as a form of faith healing and I wouldn't expect my GP to tell me to see my Priest least of all make a generous donation to the roof fund.
