歌曰 山栀香豉治何为。烦恼难眠胸窒宜。十四枚栀四合豉。先栀后豉法煎奇。
男元犀按。此汤旧本有得吐止后服等字。故相传为涌吐之方。高明如柯韵伯。亦因其说
。惟张隐庵、张令韶极辨其讹。曰。瓜蒂散二条。本经必曰吐之。栀子汤六节。并不言一吐
字。且吐下后虚烦。岂有复吐之理乎。此因瓜蒂散内。用香豉二合而误传之也。愚每用此方
。服之不吐者多。亦或有时而吐。要之吐与不吐。皆药力胜病之效也。其不吐者。所过者化
。即雨露之用也。一服即吐者。战则必胜。即雷霆之用也。方非吐剂。而病间有因吐而愈者
。所以为方之神妙。栀子色赤象心。味苦属火。性寒导火热之下行。豆形象肾。色黑入肾。
制造为豉。轻浮引水液之上升。阴阳和。水火济。而烦热懊 结痛等证俱解矣。原本列于太
阳。主解烦。非吐剂。而有时亦能涌吐也。韵伯移入阳明。只知为吐剂泄阳明之烦热。即此
为仁者见仁。知者见知也。
治栀豉汤证中若少气者主之。

Treats the condition after sweating, vomiting, or purging, characterized by empty vexation (Xu Fan), insomnia, tossing and turning restlessly, and a feeling of stifling discomfort in the heart (Xin Zhong Ao Nao).
Zhi Zi (Gardeniae Fructus, 14 pieces, raw, broken open) Xiang Chi (Fermented Soybean, 4 He, wrapped in silk gauze)
Take the above two ingredients. Add four Sheng of water. First decoct Zhi Zi until half remains (2.5 Sheng). Then add Xiang Chi. Decoct to obtain 1.5 Sheng of liquid. Remove the dregs. Divide into two doses. Take warm.
The song states: What do Shan Zhi and Xiang Chi treat? They are suitable for vexation, difficulty sleeping, and chest oppression. Fourteen pieces of Zhi Zi and four He of Xiang Chi; the method of decocting Zhi Zi first and adding Xiang Chi later is unique.
Commentary by Nan Yuanxi: In older editions of this formula, there were phrases such as "stop taking after vomiting," which led to its transmission as an emetic formula. Even brilliant scholars like Ke Yunbo followed this interpretation. Only Zhang Yinan and Zhanglingshao strongly refuted this error, stating that in the two sections regarding Gou Ti San (Melon Stalk Powder), the text explicitly says "induce vomiting," whereas in the six sections concerning Zhi Zi Tang, the character for "vomit" never appears. Moreover, if emptiness and vexation arise after vomiting and purging, how could one induce vomiting again? This misconception arose because Er He of Xiang Chi is used in Gou Ti San. In my own clinical practice, when using this formula, most patients do not vomit, though sometimes they do. Ultimately, whether vomiting occurs or not, it is all an effect of the medicinal power overcoming the pathogen. Those who do not vomit experience the transformation of pathogens, akin to the nourishing effect of rain and dew. Those who vomit after one dose experience a decisive victory over the disease, akin to the force of thunder and lightning. This formula is not an emetic, yet occasionally recovery occurs through vomiting, which demonstrates its miraculous nature. Zhi Zi is red, corresponding to the Heart; bitter in taste and associated with Fire; cold in nature, guiding fire-heat downward. The bean resembles the Kidney; black in color and entering the Kidney meridian. After processing into Xiang Chi, it becomes light and floating, guiding body fluids upward. When Yin and Yang harmonize and Water and Fire interact, symptoms such as vexation, stifling discomfort, and painful knotting are resolved. Originally listed under Taiyang disease, its primary function is to relieve vexation. It is not an emetic, but can occasionally induce vomiting. Ke Yunbo moved it to Yangming disease, believing it only clears Yangming heat via vomiting. This reflects the subjective perspectives of different scholars ("the benevolent see benevolence, the wise see wisdom").
For the Zhi Zi Chi Tang syndrome accompanied by shortness of breath (Shao Qi), this formula is indicated.
