Moxa can be a treatment in itself or used in conjunction with acupuncture. It is derived from the herb mugwort and comes in a few different forms. In stick form, Moxa is like a fragrant charcoal stick, and it is used to warm areas of the body or to bring Qi to a point or area. Moxa punk or unformed moxa, can be rolled into balls or cones and burned on needles or directly on the skin, or placed on a piece of ginger or some salt. Its effects on the body are calming, warming, blood building, and immunity enhancing.
