This kind of fat and beautiful hair, its Qi overflows, turns into thirst, treats it with orchid, and eliminates the old Qi. Wang Bingzhu Yun, Xin can spread, so also. Li Dongyuan's treatment of diabetes and drinking of orchid leaves in Zhangzhou is based on this. "Orchid grass, Eupatorium adenophorum, is fragrant and warm, pungent and dispersive. It is the Yang in Yin, and it is also the medicine of foot Taiyin and Jueyin meridians. The spleen is fond of fragrance, the liver is suitable for pungent powder, the spleen is comfortable, the Sanjiao is unblocked and healthy; the liver depression powder is popular in Ying and Wei, and the disease is pathogenic. Orchid is a good medicine to quench thirst. Eupatorium is a good medicine to quench thirst Although they are of the same kind, their functions are slightly different, just as red white Poria cocos and peony are different in reinforcing and reducing. Lei dunyan said that the female can regulate qi and generate blood, while the male can break through blood and promote accumulation, which is exactly the indication of Erlan. Eupatorium grandiflorum is a kind of orchid grass, which can be used for reference. Blood comes from Qi, so it is called regulating qi to generate blood. "

Lancao Xinping can disperse the stagnation and the fragrance can eliminate the filth. Most of the syndromes come from Liao. It is also the holy medicine of appetizing and eliminating evil, clearing lung and eliminating phlegm, and dispersing stasis. "

It can be seen that orchid grass is good at cleaning up the stomach. "

As for the effect of running water and eliminating phlegm, the two things are similar, but Eupatorium Eupatorium is superior to Eupatorium in water control, and Eupatorium Eupatorium is superior to Eupatorium in regulating qi.
