Moxibustion stimulates human acupoints through the heat generated by the burning of wormwood, regulates the functions of viscera and organs, accelerates the circulation of qi and blood in meridians, and can directly penetrate deep tissues, penetrate the whole body and improve blood circulation. Its mechanism is first related to the warm stimulation of local fire. Moxibustion has the functions of warming channels and collaterals, harmonizing qi and blood, coordinating yin and yang, strengthening body resistance and eliminating evil spirits, and maintaining health and beauty, which is beneficial to human body. However, if moxibustion is carried out every day, under this warm stimulation, and some patients are too hot, some patients will have adverse reactions such as sore mouth, dry mouth, dry stool, red and swollen back, or patients will have fever, open pores and sweating after moxibustion. Moreover, moxibustion every day increases the patient's tolerance, which easily leads to skin burns and local skin dryness. Therefore, if you do moxibustion every day, you must be careful not to spend too long. Or you can moxibustion 2~3 times a week, and drink warm water to replenish water in time after moxibustion.
