Modern research has revealed scientific reasons why acupuncture is a successful therapy. In the 1970s, reports appeared in Western medical literature suggesting that acupuncture reduces pain sensation through direct stimulation of the nerve, which changes the quality of signaling along nerve cells.

In fact, research suggests that acupuncture may suppress the nociceptive trigeminal nucleus caudalis and spinal dorsal horn neurons via modulation of the release of neuropeptides and neurotransmitters.
