This is a TCM Acupuncture treatment which usually involves the burning of a dried herb called Mugwort. When lit, it is held above or placed directly on the skin at specific acupuncture points. It is used to relieve pain and congestion and also provides an anesthetic effect. Pieces of heated ginger are used to treat stomachache, vomiting and diarrhea, as well as rheumatic pain; garlic is applied in respiratory disorders; and salt is used to stimulate the abdominal organs.
