 The US FDA classifies single-use acupuncture needles as Class II medical devices, under CFR 21.Acupuncture is often accompanied by moxibustion – the Chinese characters for acupuncture () literally meaning "acupuncture-moxibustion" – which involves burning mugwort on or near the skin at an acupuncture point.According to the American Cancer Society, "available scientific evidence does not support claims that moxibustion is effective in preventing or treating cancer or any other disease".
