Moxibustion is a technique that involves the burning of Chinese Mugwort (artemisia mugwort) on or very close to the skin. This process is used to relieve joint pain, promote circulation, and to support the immune system.

It was discovered long ago that unlike other herbs which if placed on a piece of wood burn in an outward direction, Chinese mugwort burns primarily downward allowing the heat to penetrate deeply into the body, strengthening the immune system, expelling cold from deep in the body, and warming the meridians, which leads to a smoother flow of blood and qi (chi) and pain relief.
