Moxa
Moxibustion is the burning of the herb mugwort as a form of heat therapy. It is a technique used in traditional Chinese medicine on or above specific points on the body for healing. Its purpose is to stimulate the flow of qi and blood. A great placement postpartum is over the belly button. A moxa box is commonly used to provide warmth to such area. Simply place the Moxa stick in a glass of raw, white rice to put it out.
*Note- The smell can be compared to incense, so keep that in mind before use.
