Modern research shows that the methanol extract of mugwort combustion products has the effect of scavenging free radicals, which is stronger than the methanol extract of unburned mugwort. After moxibustion, the local skin lipid peroxide decreased obviously, which was caused by the burning products of Artemisia argyi. The burning of mugwort not only did not destroy its effective medicinal components, but enhanced them. Antioxidants in the combustion products of mugwort stick to the skin at acupoints and penetrate into the body through moxibustion heat.

Moxibustion therapy has many functions. If the acupoints are different, the moxibustion methods are different, the degree of stimulation is different or the materials used in moxibustion are different, then the efficacy is different; Therefore, different acupoints and operation methods should be selected according to the specific condition in clinical application.
