1. moxa sticks mainly include moxa sticks, medicinal moxa sticks and moxa powder moxa sticks. The moxa sticks are all made of moxa sticks, excluding other materials. This kind of moxa stick is also called pure moxa stick and clear moxa stick. The effect of this kind of moxa stick is mainly determined by its purity. We often see merchants selling 35: 1 five-year gold mugwort. This ratio means that 1 kg of moxa is made of 35 kg of moxa leaves, and this kind of wool is made of strips. At present, the purity of wormwood on the market ranges from 1: 1 to 35: 1, so it is difficult to get any higher. 2. There are differences in color and smoke produced by burning moxa with different purity. The higher the purity, the milder the moxa fire. So many people put the best moxa sticks directly on the skin for moxibustion (direct moxibustion). Cashmere from 1: 1 to 5: 1 is slightly black and contains impurities and straw. Will damage the meridians in use. Most mugwort cigarettes are cyan. Cashmere from 8: 1 to 15: 1 is khaki or yellow, which is the color advocated by moxibustion experts. Moxa smoke is white. Cashmere above 15: 1 is yellow and golden yellow. Because its color is similar to that of gold, it is also called velvet gold velvet. Moxa smoke is white. 3. Powdered moxa sticks are divided into smokeless moxa sticks and smoked moxa sticks. The so-called moxa powder is the moxa leaf, the moxa powder left after crushing (machine production), or the moxa powder left after artificial crushing. Stick the moxa powder into strips, that is, cigarette moxa sticks. The moxa powder is carbonized and made into strips, which is smokeless moxa sticks. This moxa stick can also be added with medicine to achieve the purpose of special treatment and health care. 4. For family health care, it is effective, cheap and effective to use more than 8: 1. The purity is low, and it is easy to hurt meridians when the temperature explodes. Low-purity moxa sticks are mostly used in health centers, health centers and beauty salons. However, many people are not used to moxa smoke, so they will choose smokeless moxa sticks or switch to direct moxibustion with moxa sticks.
