Effects of acupuncture at GV01 on experimentally induced colitis in rats: possible involvement of the opioid system

Jpn J Physiol. 2005 Jun;55(3):205-10. doi: 10.2170/jjphysiol.S647. Epub 2005 Jun 14.

Abstract

Oriental medicine uses acupuncture at the GV01 acupoint with great success to treat diarrhea. It significantly reduced the colonic motility and inflammation in colitic rats. Naloxone pretreatment blocked these effects. The therapeutic effects of acupuncture at GV01 in colitis may involve endogenous opioid pathways.
