The old man saw from the TV, old cold leg patients through moxibustion, but magically cured, 69 years old he also can not resist, and do their own moxibustion at home. However, after only two times, he got a lot of blisters, and some of them were bleeding pus outward. The more blisters he heard, the more effective it was, so he kept doing it. “Traditional Chinese medicine believes that moxibustion blistering or pus is a manifestation of detoxification, which can indeed have a better effect, but because it is difficult to grasp the degree of blistering by itself moxibustion, too much damage to the skin, which may cause other problems, so now it is generally recommended mild moxibustion, to not blister. Generally, the time is about half an hour, about 3-5 cm from the body, depending on the principle of personal tolerance, and there is no need to force the pain. If the burning sensation is obvious, it should always be adjusted, such as further away from the body or stop treatment to avoid hurting the skin. Damage can also be reduced with the help of external appliances such as moxibustion boxes.” Moxibustion is the use of moxa as a moxibustion material, which is ignited and placed on acupuncture points or lesions to be smoked. With the combined effect of warmth and medicine, it can prevent and cure diseases by warming up the qi and blood and helping to dispel evil, and is very effective for arthritis, old cold legs and dysmenorrhea. The common moxibustion is divided into moxa cone moxibustion and moxa stick moxibustion. The operation of moxa cone moxibustion (see Figure 1) is to put a fresh ginger slice about 0.3 cm thick, pierce several holes with a needle in the middle, put a large or medium moxa cone on it and ignite it. When the patient has a local burning pain, slightly lift the ginger, or replace the cone and moxibustion. The moxa cones are mostly conical, and each burned out moxa cone is called a strong, generally 5-10 strong per moxibustion, to the degree of local flushing.
