During the acute stage, use the self-devised prescription Qingre Xiepi Decoction. This prescription has the effects of clearing heat and detoxifying, cooling blood and promoting eruption, as well as drying dampness and removing irritability. When using this prescription, it should be noted that the treatment should be stopped once the condition is under control to prevent excessive use of bitter cold herbs from easily injuring the spleen and stomach. That is, when the fever gradually subsides, the rash shrinks, and other accompanying symptoms are relieved, switch to drugs that regulate the spleen and assist transportation while clearing and transforming. It is essential to ensure that evil is removed without harming the righteous qi, and when the evil is gone, the body will be at peace.
