Also known as moxa, moxibustion is the process of burning a root called mugwort sage (artemisia vulgaris) burned at or above certain acupuncture points to elicit a therapeutic effect. It is a treatment strategy under the umbrella of traditional Chinese medicine, which also includes interventions such as acupuncture, Tuina/massage, auricular acupuncture, and acupressure. It is a simple technique that involves no pain. The effectiveness of moxibustion is two-fold: the body responds physiologically to heat stimulation generated by burning moxa, and also responds to the chemical components in mugwort leaves. Moxa is used extensively in China and a bit in the United States, but it receives far less attention than acupuncture.
