What are the four major schools of moxibustion in China?

The four major moxibustion methods in China are warm moxibustion, acupuncture, moxibustion and scrapping, which constitute the moxibustion school of traditional medicine in China. Warm moxibustion refers to the use of heat energy generated by the burning of moxibustion pot to stimulate human acupuncture points, while acupuncture regulates body functions by stimulating acupuncture points. Moxibustion acts on acupuncture points by burning mugwort leaves, scraping the surface of human body and achieving curative effect. These four moxibustion methods have their own advantages in practice and are widely used in clinical treatment and health care of traditional Chinese medicine.
