Moxa is the common name for Mugwort or the Artemisia plant. In Traditional Chinese Medicine it is burned therapeutically in several forms on areas or acupuncture points in order to stimulate a functional response in the body. It can be burned directly on the skin (direct moxa), made into a stick and held above the skin (indirect moxa), and even packed around the top of an acupuncture needle and lit in order to propagate heat down the needle (warm needle). Moxa is used in particular because the quality of heat generated by moxa if very penetrating, meaning that the heat and associated functions get into the selected points rather than simply warming the skin surface. Moxibustion is excellent for treating a wide variety of issues, such as metabolic issues, immune system function, orthopedic and pain issues, and hormone function.
