Heat headache and upset, all blood deficiency and heat Hou also, Qinggan heat and blood, headache and upset all solution. "

In addition to water gas, the pungent temperature drops, so it can dredge the collaterals and expel water. Its stem can bath rash and itch, so it can promote blood circulation and dispel wind. It's not proper to treat fever at that time. Those who treat blood adversity can move blood mildly, and the son can fall down again, so it can calm the adversity. However, it is not in accordance with the nature of warming and nourishing to have a headache and upset. "
