Compendium of Materia Medica says: "Pick out clean leaves, remove dust, put them in a mortar, tamp them with a wooden pestle, remove residues, and tamp them until they are soft and rotten like cotton. It will be effective when used. " Classic books of traditional Chinese medicine often record that impurities are easy to hurt the skin and branches damage the meridians. The moxa is fine and has no branches and impurities, so it is a good moxa for moxibustion. The quality of moxa in moxa sticks has a great influence on the effect of moxibustion. Good moxa sticks have high efficacy and good curative effect, and vice versa. Inferior moxa sticks, when burning, the fire is fierce and dry, which is easy for patients to feel burning pain and unbearable. Moreover, because there are many impurities, it often has the disadvantage of bursting when burning, and the heat of moxa fire cannot penetrate deep into the skin. Mencius Li Lou said, "Seven years of illness requires three years of love". It shows that the ancients had rich experience in choosing Ai. Three-year-old Ai is. Ai Chen has the advantages of less volatile oil, slow burning, moderate firepower, less smoke after burning, and the ash of Ai Ai is not easy to fall off. However, new love does not have these advantages. Artemisia argyi has a strong smell, contains a lot of volatile oil, and has the advantages of fast burning speed and strong firepower. After burning, there is more smoke, and the ash of Artemisia argyi is easy to fall off, which is easy to hurt the skin and blood vessels. Therefore, Ai Chen should be used to replace Ai Xin in clinic. "Compendium of Materia Medica" records that "whoever needs to use Artemisia argyi for a long time, it is delicate and soft, which is called cooked Artemisia argyi." If there is moxibustion fire, it is easy to hurt muscles. "Chen's moxibustion fire is" warm but not dry, moistening and dredging collaterals ". The color is khaki or golden yellow, and the moxa is soft and free of impurities, which is regarded as the top grade. Now green moxibustion therapy is gradually favored by Chinese people, and ordinary people have joined the group of moxibustion health care. The market is also full of inferior moxa sticks, and many manufacturers of moxa sticks don't even have product implementation standards, let alone quality control; The contact number of the manufacturer is not marked, so what is the intention? Others pretend to be the non-existent drug control machine (quasi) document number and put tiger skin on the product. Products such as moxa sticks need to be carefully identified by consumers. Moxibustion needs to find a regular manufacturer, and Dr. Ai is not bad.
