Moxibustion (Chinese: 灸; pinyin: jiǔ) is a traditional Chinese medicine therapy which consists of burning dried mugwort (moxa) on particular points on the body. It plays an important role in the traditional medical systems of China (including Tibet), Japan, Korea, Vietnam, and Mongolia. Suppliers usually age the mugwort and grind it up to a fluff; practitioners burn the fluff or process it further into a cigar-shaped stick.
