Moxa smoking does not prevent novel coronavirus infection, but it can also stimulate the body’s positive energy, mediate the body’s endocrine system, enhance the body’s resistance to disease, improve the body’s immune system, and play a preventive health care role. Moxa smoking also has the function of warming the meridians and dispersing the cold, because the new coronavirus infection causes the new coronavirus pneumonia, which is considered by Chinese medicine to be caused by excessive cold and dampness, so by smoking moxa can remove the cold and promote the body’s recovery. In addition, the warmth of the mugwort leaves can also make the pores of the skin release, so that heat has a way to go, thus playing a role in heat dissipation. However, if the duration of moxa smoking is too long, it will affect the respiratory and circulatory systems of the body, so it is recommended that the duration of moxa smoking should not be too long.
