1/20
Which herb mildly releases the exterior, meaning it can used for early-stage wind-heat or wind-cold? It also eliminates irritability; for irritability, restlessness, and insomnia after a febrile disorder.
Dan Dou Chi and Cong Bai are used together for early-stage exterior attacks. Dan Dou Chi also eliminates irritability (Shen disturbance due to heat), but that comes up in like one formula.
