Moxibustion is a warming treatment that involves burning an herb (mugwort) above
acupuncture points or regions of the body, in order to increase circulation to an area.
Moxa can be used either directly (on the skin or on the end of an acupuncture needle) or indirectly (a cigar-shaped format mixed with charcoal is held above the skin).

Moxibustion can be used to warm an injured area of the body or painful joints, or to
eliminate dampness or cold in the body.  It is also used to tonify or treat chronic
conditions, particularly in cases where the patient may be too weak for acupuncture.

Mugwort has been found useful in certain gynecological indications, as it stimulates blood flow to the uterus and pelvic region.  Its warming properties make it suitable when cold affects normal functioning of the uterus, or to turn a breech baby before labor begins (by warming a point on the little toe).
