Moxibustion treats and prevents diseases by applying heat to points or certain locations of the human body. The material used is mainly ‘moxa wool’ in the form of a cine or stick. For centuries, moxibustion and acupuncture have been combined in clinical practice, thus they are usually termed together in Chinese – zhen jiu.
The moxa leaf is bitter and acrid, producing warmth when used in a small amount and strong heat when used in large amounts.
Yang qi can be activated by the moxa leaf for its warm nature. The acrid odour of the leaf can travel through the meridians, regulate qi and blood, and expel cold from the meridians, and its bitter nature resolves dampness. As a result it is used as a necessary material in moxibustion treatment.
