A: Acupuncture is based on the assumption that Qi courses through channels in the body just as streams and rivers ebb and flow across the surface of the earth. Every Organ Network has a corresponding set of channels.
The acupuncture points are located in small depressions in the skin called "men" or "gates" where the channels come closest to the surface. In ancient times, when cities were fortified by walls, gates were opened to receive sustenance and closed to keep harm away. With acupuncture, the gates of the body are opened and closed to adjust circulation in the channels and expel noxious influences from them. Acupuncture invigorates proper function of muscles, nerves, vessels, glands, and organs.
