Ai Ye - Folium Artemisiae Argyi - Mugwort Leaf, also called moxa is Chinese herb used both orally or externally. When taken internally it can help manage gynecological disorders, eczema or skin itchiness. The back of Ai Ye contains layers of fine hair, known as moxa wool, the material used to make moxa stick. Moxa sticks are used in Moxibustion, an externally applied TCM heat therapy which consists of burning dried moxa on specific points on the body near the skin. Moxibustion is particularly helpful for people who suffer from poor circulation or cold feeling in the hands and feet.
