Discourse states: After the recovery from a cold damage disease, irritability may manifest as either empty irritability (Xu Fan) or grain irritability (Gu Fan). Empty irritability is caused by an excess of yang qi. Grain irritability occurs when food is consumed too early after the illness has subsided; the body's new weakness cannot withstand the qi of the food, leading to steaming heat in the stomach. If yin and yang are harmonized, empty irritability will resolve on its own; if dietary intake is reduced, grain irritability will heal.
For empty irritability presenting similarly to cold damage but without body pain or aversion to cold, where neither exterior nor interior methods of purgation are applicable, the Zhuye Tang (Bamboo Leaf Decoction) is appropriate.
