Moxa, or mugwart is a Chinese herb, which is burned near acupuncture points to warm regions with the intention of stimulating circulation, induces a smoother flow of blood and energy to the area, bringing vitality and health. 

Scientific research has shown that mugwort acts as an emmenagogue, meaning that it stimulates blood-flow. Clearly a potent herb,  moxibustion militates against cold and dampness in the body.

In fact, moxibustion pre-dates acupuncture, as well as needling, and is a wonderful treatment option in particular cases.
