Banxia Xiexin Decoction: a classic prescription to reconcile cold and heat

Banxia Xiexin Decoction is one of the classic prescriptions of traditional Chinese medicine. It comes from "Treatise on Febrile Diseases". It is composed of pinellia, skullcap, dried ginger, ginseng, licorice, coptis, and jujube. It is mainly used to treat symptoms such as fullness, vomiting, and diarrhea caused by mixed cold and heat and abnormal rise and fall of the spleen and stomach. This article will focus on the four aspects of prescription composition, efficacy, applicable symptoms and modern application, focusing on analyzing its compatibility characteristics of "painful and bitter, combined use of cold and heat", and will be supplemented by data to illustrate its clinical value.

The three are ministerial medicines together, forming the core of "balancing cold and heat"; ginseng, licorice, and jujube are supplementary medicines that nourish the spleen and stomach. The whole prescription restores the rise and fall of spleen and stomach qi through the method of removing pungent and reducing pain. It is especially suitable for digestive disorders caused by improper diet or invasion of external evils. Zhang Zhongjing emphasized in "Treatise on Febrile Diseases" that it is mainly used to treat "fullness in the heart without pain", and it is often used in modern times for chronic gastritis, functional indigestion and other diseases.
