There is no clinical study to show that moxibustion of the buttocks will bring obvious harm, but improper operation or not pay attention to keep warm after moxibustion will bring burns to the skin, wind and other hazards. 1. Improper operation. Moxibustion on the buttocks can accelerate local circulation and improve muscle tension in the buttocks through the heat of moxibustion, thus improving the discomfort to a certain extent. However, if the operator is not operating properly, it may cause the ash to fall on the skin and cause localized burns. Similarly, moxibustion time should not be too long to avoid burning the buttock skin. 2. Wind. Moxibustion hip often need to remove pants, exposed buttocks, and moxibustion skin pores open, more susceptible to cold. If you do not pay attention to keep warm in time, it may lead to cold and flu. It is recommended that moxibustion on the buttocks be performed by professionals to minimize the risk of these hazards.
