Three Cases of Cutaneous Warts Treated With Moxibustion

Moxibustion is a treatment that uses thermal stimulation generated when herbal materials are burned, indirectly or directly, on the affected area or acupoint. Three cases are presented to report the efficacy of direct moxibustion on cutaneous warts. Three patients with chronic cutaneous warts received direct moxibustion made of Artemisia argyi (Dongbang Inc., Chungnam, Korea). Moxa burning was performed using moxa cones. Approximately 80% of a cone was burned, until patients reported feeling a burning sensation, at which time the cone was removed and another one burned. As part of this approach, patients underwent 5–19 moxibustion procedures during and after wart removal. After warts were completely eliminated, moxa burning was performed on each patient until approximately 60% of a cone was burned or the patient felt heat sensitization but no pain. In these cases, moxibustion seemed to have an effect on cutaneous warts. A possible mechanism is that direct moxibustion likely induces tissue damage from burning and, subsequently, a wound healing effect at a different temperature level. Our reports suggest that it would be worthwhile to conduct further studies on the safety and efficacy of moxibustion on warts or to develop a medical device that uses modified moxibustion.
