Heat is a common remedy in most societies where it is applied to improve blood circulation. Moxibustion is a traditional Chinese medicine technique that involves the burning of mugwort (which comes in many different shapes and sizes) to facilitate healing. The purpose of moxibustion, as with most forms of traditional Chinese medicine, is to strengthen the blood, stimulate the flow of qi, remove colds, maintain youth, and maintain general health. It can be applied to the handle of the needle or rotated gently over the skin with qenshang and fuzi to apply heat.
