Practitioners use moxa to warm regions and meridian points with the intention of stimulating circulation through the points and inducing a smoother flow of blood and qi. Some believe it can treat conditions associated with the “cold” or “yang deficiencies” in Chinese Medicine. It is claimed that moxibustion mitigates against cold and dampness in the body, and can serve to turn breech babies.
Moxibustion is especially effective in the treatment of chronic problems, “deficient conditions” (weakness), and gerontology. Bian Que (fl. circa 500 BCE), one of the most famous semi-legendary doctors of Chinese antiquity and the first specialist in moxibustion treatment, discussed the benefits of moxa over acupuncture in his classic work Bian Que Neijing. He asserted that moxa could add new energy to the body and could treat both excess and deficient conditions.
Practitioners may use acupuncture needles made of various materials in combination with moxa, depending on the direction of qi flow they wish to stimulate.
Moxibustion is a kind of external treatment; it is based on the theory of traditional Chinese medicine (TCM), and it usually bakes acupoints with burning moxa wool. Moxibustion can dredge meridians and regulate qi-blood and has been used to prevent and cure diseases for more than 2500 years. Zuo zhuan of the pre-Qin dynasty in China, which recorded a disease discussion occurred in 581 B.C., is considered to be the earliest literature of moxibustion. The silk books discovered in Mawangdui tomb of the Han dynasty (about 168 B.C.), Moxibustion Classic of Eleven Foot-hand Meridians andPrescriptions for Fifty-two Diseases, had documented the use of moxibustion to treat complex diseases. There are a lot of moxibustion contents in Inner Canon of Huangdi; it inferred that the origin of moxibustion is related to the living habits and disease characteristics of northern Alpine nation in the part of Su wen, Yi fa fang yi lun. Later doctors after Han dynasty had made considerable progress in theory and practice on moxibustion and promoted moxibustion to be a mature and widely used therapy.
The most proper indications of moxibustion therapy are malposition, diarrhea, and colitis; the common proper indications are urinary incontinence and dysmenorrhea; the next common proper indications are knee osteoarthritis, temporomandibular joint disturbance syndrome, soft tissue injury, heel pain, asthma, urinary retention, and herpes zoster.
Moxibustion can also be used to treat weakness, fatigue, and aging related problems.
