栀子（十四枚） 甘草（二两 内台。止用半两） 香豉（四合）
上三味。以水四升。先煮栀子、甘草。取二升半。内豉。煮取升半。去滓。分温二服。

治疗经过发汗、催吐或泻下治疗后，出现心中虚烦、无法入睡，翻来覆去难以安卧，心中郁闷不舒的症状。
以上两味药，用水四升，先煮栀子，煮至剩余二升半时，加入香豉，继续煮取一升半的药液，滤去药渣，分两次温服。
歌诀说：山栀与香豉用来治疗什么？烦躁难眠、胸中窒塞适宜使用。十四枚栀子配四合香豉，先煮栀子后下香豉的煎煮方法很奇特。
男元犀按语：此方在旧版书中还有“得吐止后服”等字样，因此被相传为涌吐之方的代表。像柯韵伯这样高明的人，也沿袭了这一说法。只有张隐庵、张令韶极力辩驳其错误，他们说：瓜蒂散两条原文中，必定会写“吐之”，而栀子汤六节中，并没有出现一个“吐”字。况且是在吐下之后出现的虚烦，哪里还有再次使用吐法的道理呢？这是因为瓜蒂散中使用了香豉二合，从而导致了误传。我每次使用此方，大多数情况下服药后并不呕吐，有时也会呕吐。总之，吐或不吐，都是药力战胜病邪的效果。那些不呕吐的，是药物经过身体后化除病邪，就像雨露滋润万物一样；服用一次就呕吐的，如同作战必胜，就像雷霆万钧的威力。此方并非涌吐剂，但病情偶尔因呕吐而痊愈，这正是此方神妙的地方。栀子颜色赤红象征心脏，味道苦属火，性质寒凉引导火热下行；豆子的形状像肾脏，颜色黑入肾经。经过加工制成香豉后，质地轻浮，能引导水液上升。阴阳调和，水火既济，那么烦热、懊恼、结痛等症状也就解除了。原本将此方列于太阳病篇，主要作用是解除烦闷，它不是涌吐剂，但有时也能引起呕吐。柯韵伯将其移入阳明病篇，只知道它是通过涌吐来泄除阳明经的烦热，这真是仁者见仁，智者见智罢了。
治疗栀子豉汤证中如果伴有气短症状的，主治此方。
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.
