Moxibustion is the process where moxa sticks, made of dry mugwort leaves (Artemisia vulgaris) is ignited and held about an inch above the patients’s skin over specific acupuncture points. Moxa is available in a loose form that can be used for making moxa cones. Alternatively, moxa is packed and rolled in a long stick like a large cigar, or in small cones with a protective bottom layer that adheres to the skin (as pictured). The purpose of this process is to warm the qi and blood in the channels. Moxibustion is most commonly used when there is the requirement to expel cold and damp or to tonify the qi and blood. A single treatment of moxibustion usually lasts 10-15 minutes. Needle-warming moxibustion combines needling and moxibustion by attaching a moxa stub (about 2 cm long) to an inserted needle. This method enhances the effects of needling and is often used to treat chronic rheumatism and rheumatoid arthritis, among many other conditions.
