案据少阴篇厥阴篇之例。此条所主。当是通脉四逆汤。
吐已下断。汗出而厥。四肢拘急不解。脉微欲绝者。通脉四逆加猪胆汤主之。（成本。玉函。胆下。有汁
字。外台。不用猪胆汁。千金同。）
〔锡〕吐已下断者。阴阳气血俱虚。水谷津液俱竭。无有可吐而自已。无有可下而自断也。故汗出而厥。
四肢拘急之亡阴证。与脉微欲绝之亡阳证。仍然不解。更宜通脉四逆加
猪胆。启下焦之生阳。而助中焦之津液。〔志〕霍乱之证。至汗出而厥。四肢拘急。脉微欲绝。乃惟阴无阳。
用四逆汤。不必言矣。又加胆汁人尿者。津液竭而阴血并虚。不当但助其阳。更当滋益其阴之意。
案志聪锡驹注。本方更加人尿。然原文中无所考。盖据白通加猪胆汁汤。而有此说耳。锡驹云。每见夏
月霍乱之证。四肢厥逆。脉微欲绝。投以理中四逆。不能取效。反以明矾少许。和凉水服之。而即愈。亦即胆
汁人尿之意。先贤立法。可谓周遍详明矣。霍乱用矾石。原见于华佗危病方。与胆汁人尿。盖其意迥别。

Based on the style of the Shaoyin (Lesser Yin) and Jueyin (Terminal Yin) chapters, the formula indicated in this clause should be Tongmai Sini Tang (Pulse-Reviving Cold-Reversing Decoction).
If vomiting has ceased and diarrhea has stopped, yet sweating occurs accompanied by cold limbs, persistent stiffness and cramping of the four limbs that does not resolve, and a faint pulse nearly imperceptible, Tongmai Sini Tang with Porcine Bile is indicated. (Cheng's edition and *Jin Gui Yu Han Jing* include the character "juice" after "bile"; *Wai Tai Mi Yao* does not use porcine bile, consistent with *Qian Jin Fang*.)
[Commentary by Xi Ju] When vomiting ceases and diarrhea stops, it is because both Yin and Yang, Qi and Blood are deficient, and the fluids and essence from food and drink are exhausted. There is nothing left to vomit, so it stops naturally; there is nothing left to purge, so diarrhea stops naturally. Consequently, sweating and cold limbs occur, representing a syndrome of Yin exhaustion, while the faint, nearly imperceptible pulse represents a syndrome of Yang exhaustion. Since these conditions persist, one should further utilize Tongmai Sini Tang with Porcine Bile to stimulate the generating Yang of the Lower Jiao and assist the fluids of the Middle Jiao.
[Commentary by Zhi Cong] In cases of Huoluan (Vomiting-Regurgitation and Diarrhea Syndrome), when the condition progresses to sweating, cold limbs, persistent limb stiffness/cramping, and a faint, nearly imperceptible pulse, it indicates an excess of Yin and absence of Yang. The use of Sini Tang is self-evident. The addition of bile and human urine implies that since fluids are exhausted and Yin blood is also deficient, treatment should not merely tonify Yang but also nourish and benefit Yin.
Note: Both Zhi Cong and Xi Ju mention the addition of human urine to this formula in their commentaries, but this cannot be verified in the original text. This assertion likely stems from the precedent set by Baitong Tang with Porcine Bile. Xi Ju stated: "I often see cases of summer Huoluan where limbs are cold and pulse is faint/nearly imperceptible. Administering Lizhong Tang or Sini Tang yields no effect. However, administering a small amount of alum mixed with cool water results in immediate recovery." This reflects the intent behind using bile and human urine. The legislative principles of the sages were indeed comprehensive and clear. The use of alum for Huoluan originally appeared in Hua Tuo's formulas for critical illnesses, which differs significantly in intent from the use of bile and human urine.
**Tongmai Sini Tang with Porcine Bile Formula**
Gancao (Licorice Root, 2 liang, honey-fried)
Ganjiang (Dried Ginger, 3 liang; up to 4 liang for robust individuals)
Zhuzhilian (Porcine Bile, 0.5 he) (*Jin Gui Yu Han Jing* states 4 he; *Zhou Hou Bei Ji Fang* states 1 he)
Fuzi (Aconite Root, 1 large piece, raw, skin removed, broken into 8 slices)
Take the above four ingredients, decoct in 3 sheng of water until 1.2 he remains. Strain the dregs, add the porcine bile, and divide into two warm doses. If the pulse returns, it indicates efficacy. If porcine bile is unavailable, sheep bile may be substituted.
[Commentary by Wu Qian] Sweating and cold limbs indicate that Yang is weak and nearly extinct, while persistent stiffness and cramping of the four limbs suggest a lack of blood to soften the sinews. A faint, nearly imperceptible pulse confirms impending Yang collapse, compounded by Yin deficiency. Therefore, Tongmai Sini Tang is used to restore Yang, and porcine bile is added to nourish Yin. This ensures that the nearly extinct Yin fluid is not seized and depleted by the hot Yang-tonifying herbs. Commentators who argue that extreme Yang deficiency and extreme Yin excess require counter-agent methods to overcome rejection are mistaken. (Note: Cheng Wuji, Fang Youzhi, Qian Huang, and *Yi Zong Jin Jian* agree with this view.)
Cheng Yunbo stated: "Even if vomiting and diarrhea have ceased, Yin pathogens may remain firmly entrenched, making it difficult for Yang Qi to extend. Thus, symptoms manifest as sweating, cold limbs, unresolved limb stiffness, and a faint, nearly imperceptible pulse. This formula addresses such cases, facilitating the communication of Qi amidst the rescue of Yang and emergency revival. Even post-recovery management is challenging in such severe cases. How can one not exercise caution at the onset?" Note: This is another interpretation, preserved here for reference.
In cases of Huoluan with vomiting and diarrhea, followed by diaphoresis, if the pulse becomes normal but slight irritability persists, it is due to the newly weakened state being unable to handle the qi of grain (food digestion burden). (This clause appears in the chapter on Post-Diaphoresis, Post-Purging, etc., where the character 'hou' [after] follows 'han xia'.)
[Commentary by Wei Litong] After vomiting, diarrhea, and diaphoresis, if the pulse becomes normal and the illness resolves, this indicates that the patient had abundant Stomach Qi normally, and the pathogenic factor was mild. The residual slight irritability arises because the Stomach Qi was suddenly depleted by vomiting and diarrhea; it is not a constitutional deficiency but a new, acute deficiency. If the diet remains at the previous volume, the qi of grain will exceed the capacity of the weakened Stomach Qi, causing slight irritability due to inability to process the food. Zhang Zhongjing did not specify a treatment method because the remedy—reducing dietary intake—is already covered in the clauses regarding convalescence after major illnesses. Thus, no further elaboration is needed. This principle applies to all diseases.
