Moxibustion is a combined phytotherapy/herbal medicine and heat therapy. There are various methods of using moxa (made out of Artemisia vulgaris), but the most common method is to use a moxa cigar or to put a small piece of moxa on a needle. The cigar (or needle) is used to heat certain acupuncture points on the body, in order to stimulate the flow of Qi. This form of treatment is a very popular and frequently-applied form of the traditional Chinese medicine / TCM.
Moxibustion is usually used to treat coughs, colds, humidity and cold conditions, as well as lethargy. Moxa can also be preventative, however, and moxibustion treatment can effectively strengthen the body and immune system.
