Researchers found acupuncture gives more than a “placebo effect”, and the results are published in the National Institute for Health Research Journals Library. The team worked with scientists from the UK and US to bring together the results of 29 clinical trials about acupuncture, and their report shows adding acupuncture to standard care significantly reduced headaches and migraine attacks, reduced the severity of neck and back pain, and reduced the pain of osteoarthritis.
