Moxibustion is a form of heat therapy which involves the burning of a Chinese herb called mugwort on or near an acupuncture point to warm the area and meridian-organ system. The herb comes pre-rolled as a cigar which is then lit and held close to the skin and then removed before it becomes too hot for the patient. A loose form of the herb is sometimes moulded into cone shapes which are then placed directly on the skin or on top of a slice of ginger or layer of salt. The burning herb is removed before becoming too hot and leaves no burning or scarring on the skin.

Moxibustion are often used as part of an acupuncture treatment.
