'Acupuncture works by releasing 

natural painkiller into body'

Paris: Acupuncture eases pain in the limbs because it releases a natural molecule called adenosine, US neuroscientists reported on Sunday.

        The mechanism was discovered through experiments in lab mice, which were given an injection of an inflammation-inducing chemical in their right paw. The researchers inserted fine needles below the midline of the mice's knee, at a well known acupuncture location called the Zusanlipoint. They rotated the needle gently every five minutes for 30 minutes, mimicking a standard acupuncture treatment.

       During and just after this operation, levels of adenosine in the tissues surrounding the needle surged 24-fold. The mouse's discomfort-measurable by the rodents' response time to touch and heat - was reduced by two-thirds. The same test was carried out on mice that had been genetically engineered to lack adenosine. The acupuncture failed to have any effect, and the mice reacted in discomfort, as before.
