The original name of Shutiao Decoction is Shutiao Qiji Decoction. It is a clinical effective prescription summarized by Researcher Zhang Zhen, a renowned traditional Chinese medicine master, based on his years of in-depth clinical experience. Researcher Zhang Zhen has his own unique insights into the thinking of the prescription and drug selection of Shutiao Qiji Decoction. On the basis of considering the overall effect of the prescription, he is more rigorous in examining the single drug pairs and multi-drug pairs within the prescription. Especially for the single drug Zhi shi (Fructus Aurantii Immaturus), apart from its own efficacy, it is also examined in combination with other drugs in Shutiao Decoction to form drug pairs, based on the physiological characteristics of the Zangfu organs, mutually enhancing each other‘s functions. The "Zhishi- Baishao" (Fructus Aurantii Immaturus-Radix Paeoniae Alba) and "Zhishi-Chaihu" (Fructus Aurantii Immaturus-Radix Bupleuri) drug pairs form an internal and external linkage of Qiji, and the "Zhishi-Baishu" (Fructus Aurantii Immaturus-Radix Atractylodis Macrocephalae) drug pair also takes into account the overall situation, nourishing the liver and softening it, fundamentally regulating Qiji and restoring the functions of the Zangfu organs, achieving the purpose of integrating regulation and nourishment. The exquisite thinking of drug pairing and combination is worthy of the younger generation to learn. Now, I will summarize and elaborate on it for readers.
