Moxa is also known as mugwort, an herb that is warmed over acupuncture points to warm regions and acupuncture points with the intention of stimulating circulation through the points and inducing a smoother flow of blood and qi. Scientific research has shown that mugwort acts as an emmenagogue, meaning that it stimulates blood-flow in the pelvic area and uterus. It is claimed that moxibustion militates against cold and dampness in the body and can serve to turn breech babies. Practitioners consider moxibustion to be especially effective in the treatment of chronic problems, “deficient conditions” (weakness), and gerontology. It is said that moxa can add new energy to the body and treat both excess and deficient conditions.
