凡通利大便，若用大黄、巴豆等药而大便不通者，阴阳关隔，水火不升降故也。有热者，

脾肾交济，所以有水谷之分，脾气虽强，而肾气不足，故饮食下咽而大肠为之飧泄也。
治法∶二神丸用故纸、肉豆蔻修合，或不换金正气散吞安肾丸主之。盖脾肾之气交通，则水
谷自然克化，此所谓妙合而凝者也。
有脾泄，有肾泄。脾泄者，肢体重着，中脘有妨，面色虚黄，腹肚微满。肾泄者，肤腠
怯冷，腰膂酸疼，上咳面黧，脐腹作痛。治脾泄，用苍术、白术、浓朴、干姜、木香、生肉
豆蔻辈。治肾泄，用补骨脂及安肾丸、震灵丹辈。
诸有泄泻，用不换金正气散、除湿汤之类，以去风湿，以安肠胃，此上品药也。次则温

阴阳离绝也，识者忧焉。
大人小儿，泄痢无已，其后变作白脓点滴而下，或于粪尾见之，为之温脾不愈，法当温

凡是通利大便，如果使用大黄、巴豆等药物而大便仍然不通的，这是阴阳之气相互阻隔，水火二气不能正常升降的缘故。属于热证的，用来自复丹配合三黄丸，以薄荷泡制的汤剂送服；不属于热证（无热）的，用养正丹配合神保丸，以橘皮煎煮的汤剂送服。
脾与肾相互协调济助，从而区分水谷精微与糟粕。脾气虽然强健，但如果肾气不足，就会导致饮食咽下后大肠发生完谷不化的泄泻。治疗方法：使用二神丸，由补骨脂、肉豆蔻炮制合和而成；或者使用不换金正气散吞服安肾丸来主治。因为脾肾之气交通顺畅，那么水谷自然能够消化转化，这就是所说的“妙合而凝”的道理。
有脾泄，也有肾泄。脾泄的症状是肢体沉重困着，中脘部感觉痞塞不适，面色虚黄，腹部微微胀满。肾泄的症状是肌肤腠理怕冷，腰脊酸痛，向上咳嗽且面色晦暗，脐腹部疼痛。治疗脾泄，使用苍术、白术、厚朴、干姜、木香、生肉豆蔻这一类药物。治疗肾泄，使用补骨脂以及安肾丸、震灵丹这一类药物。
各种类型的泄泻，可以使用不换金正气散、除湿汤之类的方剂，用来祛除风湿，安定肠胃，这属于上等的治法。其次则是温补脾胃的药剂，投用这些是正规的方法。然而，如果使用了这些方法却不见疗效，并且腹痛游走不定，或脐间隐隐作痛，腰脊疼痛酸软，骨骼关节软弱无力，面色枯槁憔悴，尺脉虚弱，病位在哪里呢？回答说：这是肾泄。应当用炒补骨脂、生干姜、官桂、木香、当归这一类药物为主治，同时仍需用安肾丸作为辅助。如果是肾阴枯竭，心火亢盛上炎，出现口干燥渴、小便频多、饮水无度的症状，这是阴阳离绝的危象，明眼人对此感到担忧。
大人和小孩，泄泻痢疾不止，后来变作白脓点滴而下，或者在粪便末尾见到，如果用温脾的方法治疗无效，法则应当温补肾肾。因为肾主骨髓，白脓是骨髓的异名。总之，起初发作的是白痢，气味腥臭，经过攻下治疗后，而且拖延日久，流涎不止，就不再称为痢疾了。现在的白脓，完全没有腥臭味，面色微黑，筋骨力量羸弱，确凿地显示出肾虚，应当使用炒补骨脂、当归、木香、干姜、官桂为主治，随后少量给予震灵丹或玉华白丹作为辅助。虽然如此，还有一种妇女的病证，似痢非痢，泄下白脓，心腹突然剧烈疼痛，吼叫声不忍听闻，这应当为之疏通血脉，投用活血通血的药剂，转而用养正丹来辅佐。
Whenever purgatives are used to promote bowel movement, if the bowels remain unopened despite the use of drugs such as *Rhei Radix et Rhizoma* (Dahuang) and *Crotonis Fructus* (Badou), it is due to the mutual obstruction of Yin and Yang Qi, resulting in the failure of Water and Fire to ascend and descend. For cases with heat, *Laifu Dan* (Return-to-Life Pill) combined with *Sanhuang Wan* (Three-Yellows Pill) should be administered, taken down with a decoction infused with *Menthae Haplocalycis* (Bohe). For cases without heat, *Yangzheng Dan* (Nourish-Righteousness Pill) combined with *Shenbao Wan* (Spirit-Preserving Pill) should be administered, taken down with a decoction of *Citri Reticulatae Pericarpium* (Chenpi).
The harmonious interaction between the Spleen and Kidney allows for the differentiation of water and grain. Although the Spleen Qi may be strong, insufficiency of Kidney Qi leads to undigested food passing into the Large Intestine, causing diarrhea (*Sunxie*). The treatment method involves using *Ershen Wan* (Two-Geniuses Pill), compounded from *Psoraleae Fructus* (Guzhi) and *Myristicae Semen* (Roudoukou); alternatively, *Buhuanjin Zhengqi San* (Unchanging-Gold Rectifying-Energy Powder) can be used to swallow *Anshen Wan* (Peace-Kidney Pill). When the Qi of the Spleen and Kidney communicates smoothly, water and grain are naturally digested and transformed; this is referred to as "subtle integration and condensation."
There is Spleen-diarrhea and Kidney-diarrhea. Symptoms of Spleen-diarrhea include heavy and adherent limbs, a sensation of obstruction in the epigastrium (Zhongwan), a sallow complexion, and slight abdominal distension. Symptoms of Kidney-diarrhea include aversion to cold in the skin and pores, soreness and pain in the lower back, coughing accompanied by a darkened complexion, and pain in the umbilical and abdominal regions. To treat Spleen-diarrhea, herbs such as *Atractylodis Rhizoma* (Cangzhu), *Atractylodis Macrocephalae Rhizoma* (Baizhu), *Magnoliae Officinalis Cortex* (Houpo), *Zingiberis Rhizoma* (Ganjiang), *Aquari Flos* (Muxiang), and raw *Myristicae Semen* (Roudoukou) are employed. To treat Kidney-diarrhea, *Psoraleae Fructus* (Buguzhi), along with *Anshen Wan* and *Zhenling Dan* (Vibrating-Spirit Pill), are used.
For various types of diarrhea, formulas such as *Buhuanjin Zhengqi San* and *Chushi Tang* (Dampness-Removing Decoction) can be used to dispel wind-dampness and stabilize the intestines and stomach; these are considered superior treatments. Next in hierarchy are agents that warm the Spleen and nourish the Stomach, which constitute the orthodox method. However, if these methods prove ineffective, and abdominal pain migrates up and down, or there is dull pain in the umbilical region, soreness and pain in the lower back, weakness in the bones and joints, a withered and haggard complexion, and a weak Chi pulse, where lies the disease? It is said: this is Kidney-diarrhea. One should primarily use fried *Psoraleae Fructus* (Guzhi), raw dried *Zingiberis Rhizoma* (Ganjiang), *Cinnamomi Cortex* (Guangui), *Aquari Flos* (Muxiang), and *Angelicae Sinensis Radix* (Danggui), while still employing *Anshen Wan* as an adjunct. If Kidney-Yin is exhausted and Heart-Fire flares upward, leading to dry thirst, polyuria, and excessive drinking, this indicates the separation of Yin and Yang, a condition that astute physicians regard with concern.
In adults and children, if diarrhea and dysentery persist indefinitely, they may later transform into white pus dripping down, or appearing at the end of the stool. If warming the Spleen fails to cure it, the principle dictates warming the Kidney. Since the Kidney governs bone marrow, white pus is another name for bone marrow. Essentially, initial white dysentery has a fishy odor; after purgation and prolonged duration with salivation, it no longer qualifies as dysentery. The current white pus lacks any fishy odor, the complexion is slightly black, and physical strength is emaciated, clearly indicating Kidney deficiency. The appropriate prescription includes fried *Psoraleae Fructus* (Guzhi), *Angelicae Sinensis Radix* (Danggui), *Aquari Flos* (Muxiang), *Zingiberis Rhizoma* (Ganjiang), and *Cinnamomi Cortex* (Guangui), followed by small doses of *Zhenling Dan* or *Yuhua Bai Dan* (Jade-White Pill) as auxiliaries. Nevertheless, there is another syndrome in women that resembles dysentery but is not dysentery, characterized by the discharge of white pus and sudden severe pain in the heart and abdomen, accompanied by unbearable roaring sounds. This requires promoting blood circulation through blood-invigorating agents, assisted by *Yangzheng Dan*.
