Moxabustion is the burning of an herb called mugwort (Artemisia argyi) to warm acupuncture points. It can be burned over points using cones or in hand-held tubes. Moxabustion and heat therapy in general can provide energy to an area and increase circulation of blood and Qi. It is especially indicated for chronic pain, areas that appear or feel cold on the body, and tiredness conditions, but has many other uses. Moxabustion is often prescribed for home use.
