Study reveals acupuncture's ability to reduce pain : A team of researchers led by Dr. Maiken Nedergaard of the University of Rochester have discovered why acupuncture is able to alleviate pain. Surprisingly, it isn't all attributable to the placebo effect. In a study published online this weekend in Nature Neuroscience, mice with sore paws were given half-hour acupuncture sessions. The researchers found that rotation of the acupuncture needles damaged tissue, which caused a release of adenosine, a known anti-inflammatory mediator. Mice which lacked adenosine receptors did not benefit from acupuncture treatment, which further supports the study's findings.
