Ancient doctors in China have long recognized the importance of disease prevention, and put forward the academic ideas of "prevention before illness" and "treatment before illness". Moxibustion not only has therapeutic effect, but also has the function of disease prevention and health care. It is one of the methods of disease prevention and health care and has been recorded in many ancient documents. It was mentioned as early as Huangdi Neijing. In order to prevent rabies, it is necessary to moxibustion the top three places bitten by dogs, that is, moxibustion with the method of dog injury. "Prepare a thousand dollars" says: "Every official who travels in Wu and Shu often needs moxibustion in three or two places. If you don't make the sore temporarily, the furuncle will not hurt people. " It shows that moxibustion can prevent infectious diseases. Acupuncture Dacheng mentioned that moxibustion at Zusanli can prevent stroke. There is a folk saying that "if you want to be healthy, Li Sanchang will not do it" and "Li Sanjiu cures all diseases". Because moxibustion can warm yang and tonify deficiency, moxibustion at Zusanli and Zhongwan can make the stomach full of qi, and the stomach is a sea of water valleys, and all the five internal organs are affected by it, so the stomach is full of qi, so the qi and blood are full; Mingmen is the true fire of human body and the foundation of human beings; Guanyuan and Qihai are places where Jingxue is stored. Acupoint moxibustion can make people feel full of stomach qi, Yang Qi and essence and blood, thus enhancing the body's resistance, making diseases and pathogens difficult to commit, and achieving the purpose of disease prevention and health care. In modern times, the disease prevention and health care function of moxibustion has become one of the important health care methods. So it is useful for children to do moxibustion, but moxibustion is a process that needs to be adhered to.

But we should pay attention to these taboos of moxibustion. Because moxibustion is smoked by fire, careless moxibustion may cause local skin burns. On the other hand, in the process of moxibustion, some parts or people can't be moxibustion. These are all taboos of moxibustion. There were many taboos about moxibustion in ancient times. Although some taboos can be broken, some situations should be taboo. 1. All exposed parts, such as the face, should not be directly moxibustion, so as not to form scars and affect the appearance. 2. Do not apply moxibustion to areas with thin skin and few muscles, waist and sacrum of pregnant women, lower abdomen, nipples, genitals and testicles of men and women. In addition, do not directly moxibustion joints. In addition, don't moxibustion big blood vessels and heart. The eyeball belongs to the face, so don't moxibustion. 3. Extreme fatigue, hunger, satiety, drunkenness, excessive sweating, emotional instability, or female menstrual taboo moxibustion. 4. Some infectious diseases, such as high fever, coma, convulsions, or extreme physical exhaustion, skinny and so on, should be avoided. 5. People who have no self-control ability such as mental patients should avoid moxibustion.

Now research has confirmed that moxibustion has a magical effect because the combined action of heat and moxa can produce chemicals with therapeutic effects, which have the functions of antioxidation and scavenging free radicals. Through the action of heat, not only the effective drug components in the moxa stick are not destroyed, but they are enhanced and attached to the acupoints, and the moxibustion heat penetrates into the body to play a role. The infrared rays generated during moxibustion can provide necessary energy for metabolic activity and immune function of body cells, and can also provide activation energy for pathological cells.

Ai Zhen popularizes what is free radical here. In our world composed of atoms, there is a special law, that is, as long as there are more than two atoms combined together, its peripheral electrons must be paired. If there is no pairing, they will look for another electron and turn themselves into a stable substance. Scientists call this atom or molecule with unpaired electrons a free radical. Free radicals are very active and restless. Just like lonely bachelors in our human society, if they always can't find an ideal partner, they may become a factor of social instability. Generally speaking, life is inseparable from free radical activities. Our bodies are moving from the inside out all the time, burning energy all the time, and the porter responsible for transmitting energy is free radicals. When these free radicals that help energy conversion are enclosed in cells and cannot run around, they are harmless to life. However, if the activity of free radicals is out of control and exceeds a certain amount, the normal life order will be destroyed and diseases may follow.
