There are several methods of moxibustion. Three of them are direct scarring, direct non-scarring, and indirect moxibustion. Direct scarring moxibustion places a small cone of moxa on the skin at an acupuncture point and burns it until the skin blisters, which then scars after it heals. Direct non-scarring moxibustion removes the burning moxa before the skin burns enough to scar, unless the burning moxa is left on the skin too long. Indirect moxibustion holds a cigar made of moxa near the acupuncture point to heat the skin, or holds it on an acupuncture needle inserted in the skin to heat the needle. There is also stick-on moxa.
