The technique of moxibustion uses the application of burning herbs, and specifically mugwort (Artemesiae vulgaris), at or close to acupuncture points on the body. It is used to warm cold areas, stimulate blood flow and tonify any depletions. Furthermore, when the produced resin or smoke is absorbed via the skin, Moxibustion creates an analgesic effect due to its camphor-like characteristics.
After processing, moxa is firmly packed into sticks that are ready to use. Additionally, it can be purchased loose and formed into balls that are positioned on needles to enhance the effect; it can be applied near the skin on a barrier like salt or a slice of ginger; or it can be applied directly to the skin in tiny pieces the size of a rice grain.

Low back pain, diarrhea, abdominal pain, gastroenteritis, intestinal disorders, vomiting, skin infections, arthritis, rheumatic pain, numbness, muscular pain, and chronic illnesses are only some of the ailments that respond well to moxa treatment.
Direct moxa administration may cause small, transient blisters on the skin. These are a common side effect of treatment and there are no cause for alarm. Patients who keloid or scar easily, however, should communicate it in advance so that alternative types of moxa can be used.
