Moxa is made from the herb Mugwort or Artemisia Vulgaris and is used in conjunction with acupuncture needles. The plant is dried, powdered and then formed into a wool-like substance. It is then burned on or above the skin to release its therapeutic properties at the location of acupuncture points. This practice is called Moxabustion. When burned moxa penetrates the acupuncture channels, increasing warmth, energy (Qi), blood flow, circulation, eliminating cold and the accumulations of fluids. Modern research has shown that Moxa increases the production of white and red blood cells improving blood and lymph circulation and is extremely effective for long standing chronic disease of the internal organs. Burning moxa has a distinct odor that patients generally report as having a pleasant and relaxing smell. The essential oils in the plant have a significant effect as a form of aromatherapy or medicinal incense. A large part of its healing ability is not just the warmth it provides but also the smell of the burning oils.
