[discussion by famous experts] 1. In the compendium of Medical Sciences, Mahuang's sweating Qi can't be controlled by driving, but it can stop sweating at the root. Spontaneous sweating has rheumatism, cold, wind temperature, Qi deficiency, blood deficiency, spleen deficiency, yin deficiency, stomach heat, phlegm, heat stroke, dead Yang, soft spasm and other symptoms, which can be used with syndrome. Danggui Liuhuang decoction combined with ephedra can cure night sweats, which can cover the body muscle surface. Therefore, it can lead all kinds of drugs to Wei Fen and consolidate the principle of Li. In the book of Materia Medica, you know how to attack, but you don't know how to take bait. "

② According to the book of materia medica: "Mahuang root node, Guyun antiperspirant, is a kind of antiperspirant medicine, which can achieve quick effect on the surface. It is not Mahuang root node that can stop perspiration, and the old solution is often wrong. "

③ "Materia medica justice" says: "ephedra perspires, and its root is specialized in stopping perspiration. In the past, it was called the strangeness of physics. I don't know that ephedra is light, so I sweat. Its root is deep in the soil, so it can't be the same as its rising. Kuang Miao is light, roots are heavy fall, a rise and a fall, of course. However, if they are the same book, it is still possible to make light use of the nature of expression. Therefore, it is possible to collect them from the expression of expression, to disperse them, to restrain them from being frivolous, and to return them to the interior. It is the nature of root fixation and restraint, and it can not sweat, but can make the sweat out of the body. This is why Mahuang root has the ability to stop sweating, and it is also effective. For example, the root of glutinous rice, dried peach, wheat, and jujube kernel are used to stop perspiration. They all have the same purpose. The root of Mahuang is the same as the root of Mahuang.
