烧盐（二两），温水（二升）
服之探吐。
经云∶升降出入，无器不有。故不升则不降，而道器灭矣。是以观于注水之瓶，上窍通
，则下窍自利。此用吐之意也！
宋季饶医熊彦诚，年五十五岁，病前后便溺不通五日，腹胀如鼓；同辈环视，皆不能措
力。与西湖妙果僧慧月相善，遣信邀至诀别。月惊驰而往，于钓桥逢一异客楫之曰∶方外高
人，何孑孑走趋若是？月曰∶一善友久患秘结病危，急欲往问。客曰∶易事耳，待奉施一药。
即脱靴入水探一大螺而出曰∶事济矣！抵家以盐半匙，和壳生捣，置病者脐下一寸三分，用
宽帛紧系之，仍办溺器以须其通。月未以为然，姑巽谢之。至熊家，彦诚昏不知人，妻子聚
泣。诸医知无他策，慢使试之，曾未安席而暴下，诸医愧叹而散。月归访异人，无所见矣。
熊后十六年乃终。昆谓便溺不通者，热秘之也。大螺性寒而善厘清，故浊水之中，一着大螺，
便能澄澈。剂之以盐，取其善润而已。
叙曰∶溲溺惟宜，形气治也。溲溺不禁，形气病也。轻者脬中有痹气，重者大气虚而且
绝尔。辩此者以他证合之。姑考四方以志大法。
乌药 益智仁（等分）
共为末，山药糊为丸梧子大。每服七十丸，空心盐汤下。
脬气虚寒，小便频数，遗尿不止者，此方主之。
脬气者，太阳膀胱之气也。膀胱之气，贵于冲和，邪气热之则便涩，邪气实之则不出。
正气寒之则遗尿，正气虚之则不禁。是方也，乌药辛温而质重，重者坠下，故能疗肾间之冷
气。益智仁辛热而色白，白者入气，故能壮下焦之脬气。脬气复其天，则禁固复其常矣。
烧盐（二两），温水（二升）
服用后诱发呕吐。
《内经》说：升降出入，没有哪个脏腑器官是不具备的。所以如果不升则不能降，而生命之道和脏腑功能就会衰竭。因此观察注水的瓶子，上面的孔窍通畅，下面的孔窍自然就能流出水来。这就是使用催吐法的用意！
宋代末年，杭州有一位姓熊名彦诚的医生，五十五岁，患病前后大小便不通已有五天，腹部胀大如鼓；同辈的医生围观，都束手无策。他与西湖妙果寺的僧人慧月关系很好，派人送信邀请慧月前来诀别。慧月惊慌地赶去，在钓桥遇到一位奇特的客人，那人摇着船桨对慧月说：“出家人，为什么如此匆忙奔走？”慧月说：“一位好朋友长期患有便秘病危，我急着要去探望。”客人说：“这是容易的事，让我献上一药方。”随即脱下靴子在水中摸索出一个大螺蛳出来，说：“事情办成了！”回到家后，取半匙盐，连同螺壳一起生捣碎，敷在病人脐下一寸三分处，用宽布带紧紧系住，同时准备好接尿器等待其通利。慧月起初不以为然，只是委婉地推辞道谢。到了熊家，彦诚已经昏迷不省人事，妻子儿女围聚哭泣。众位医生知道没有其他办法，便勉强让他试试这个方法，还没等坐定，病人就突然大便暴下，众医生羞愧感叹后散去。慧月回去寻找那位奇人，却再也见不到了。熊彦诚之后过了十六年才去世。吴昆认为，大小便不通，属于热秘证。大螺蛳性寒且善于澄清，所以在浑浊的水中，只要放入一个螺蛳，就能使水变得清澈。用药中加入盐，是取其润燥的作用而已。
序言说：小便排泄正常，说明形体和气机调和。小便失禁，说明形体和气机有病。轻症是膀胱中有痹阻之气，重症则是元气虚衰且将绝。辨别这种情况要结合其他症状来分析。姑且考察各地的方法以记录大法。
乌药、益智仁（各等分）
共研为细末，用山药糊制成梧桐子大小的丸药。每次服用七十丸，空腹时以盐汤送服。
膀胱气虚寒，导致小便频数，遗尿不止的，此方主治。
所谓膀胱气，是指足太阳膀胱经的气化功能。膀胱的气化功能，贵在冲和平衡，邪气热盛则小便涩滞，邪气实盛则小便不出。正气受寒则遗尿，正气虚弱则无法固摄。这个方剂中，乌药辛温且质地沉重，质重者能下行，所以能治疗肾间的冷气。益智仁辛热且色白，白色入气分，所以能补益下焦的膀胱气。膀胱气恢复了其本来的状态，那么固摄功能也就恢复正常了。
Salt (Burnt) (2 liang), Warm Water (2 sheng)
Take to induce vomiting.
The Classics state: Ascending, descending, exiting, and entering are present in every organ. Therefore, if there is no ascending, there can be no descending, and the Dao of organs would cease. Thus, observing a water-filled bottle, if the upper orifice is open, the lower orifice will naturally allow flow. This illustrates the rationale for using emesis!
In the late Song Dynasty, a physician named Xiong Yancheng from Hangzhou, aged fifty-five, suffered from inability to urinate or defecate for five days, with his abdomen distended like a drum; his colleagues watched helplessly, unable to exert any effort. He was on good terms with Huiyue, a monk at Miaoguo Temple in West Lake, and sent a messenger to invite him for a final farewell. Huiyue rushed over in alarm and met an unusual guest on Diaqiao Bridge who rowed his boat and asked, "Reverend, why do you hurry so frantically?" Huiyue replied, "A good friend has been critically ill with severe constipation for a long time, and I urgently wish to visit him." The guest said, "This is an easy matter; let me offer a remedy." He immediately took off his boot, reached into the water, and pulled out a large snail, saying, "The task is accomplished!" Upon arriving home, he took half a spoonful of salt, crushed it raw together with the snail shell, applied the mixture to the area one cun three fen below the patient's umbilicus, tied it tightly with a wide cloth strip, and prepared a urinal to await its effect. Huiyue initially did not believe in this method but politely declined. Upon reaching Xiong's house, Yancheng was unconscious, surrounded by weeping family members. Knowing there were no other options, the physicians reluctantly allowed the trial. Before he could even sit down, the patient suddenly had a massive bowel movement. The physicians, ashamed and amazed, dispersed. Huiyue returned to seek the strange man but found no trace of him. Xiong Yancheng lived for another sixteen years before passing away. Kun believes that the inability to urinate or defecate constitutes Heat Constipation (Re Mi). The large snail is cold in nature and excels at clarifying turbidity; thus, in muddy water, the introduction of a single snail makes it clear. Salt is added to the formula for its moistening properties.
Preface states: Proper urination indicates harmonious form and Qi. Incontinence indicates pathology of form and Qi. Mild cases involve Bi Qi (obstructive Qi) in the bladder; severe cases involve deficiency and exhaustion of the Great Qi. Differentiation requires combining these signs with other symptoms. Here, methods from various regions are recorded to preserve the great principles.
Wuyao (Linderae Radix), Yizhiren (Alpiniae Oxyphyllae Fructus) (Equal parts)
Grind into powder, make pills with Chinese Yam paste, sized like wutong seeds. Take seventy pills per dose, administered on an empty stomach with salty water.
This formula is indicated for Bladder Qi Deficiency-Cold presenting as frequent urination and continuous enuresis.
Bladder Qi refers to the Qi transformation of the Foot-Taiyang Bladder Meridian. The Qi of the Bladder values balance and harmony. If pathogenic Heat affects it, urination becomes difficult; if Pathogenic Excess affects it, urination is retained. If Cold affects the Healthy Qi, enuresis occurs; if Healthy Qi is deficient, incontinence results. In this formula, Wuyao is acrid-warm and heavy in texture; heaviness descends, so it treats Cold Qi in the Kidney region. Yizhiren is acrid-hot and white in color; white enters the Qi level, so it strengthens the Bladder Qi of the Lower Jiao. Once Bladder Qi recovers its natural state, its controlling function returns to normal.
