产后肠胃虚怯，寒邪易侵。若未盈月，饮冷当风，乘虚袭留于盲膜，散于腹胁，故腹痛作阵，或如锥刀所刺。流入
大肠，水谷不化，洞泄肠鸣，或下赤白， 胁 胀，急服调中汤立愈。若医者以为积滞取之，祸不旋踵，谨之谨之。
薛立斋曰∶产后泻痢，或因饮食损伤脾土，或脾土虚不能消食，当审而治之。若米食所伤，用六君加谷芽；若面食
所伤，用六君子加麦芽；若肉食所伤，用六君加山楂、神曲。凡兼呕吐者，加藿香；若兼吞酸或呕吐，用前药送越鞠丸；
若肝木侮土，用六君子加紫胡、炮姜；若寒水侮土，用钱氏益黄散；久泻元气下陷，用补中益气汤及四神丸；命门火衰
不能生土者，用八味丸以补土母；若小便涩滞，肢体渐肿，或兼喘咳，用金匮肾气丸。

产后时期，肠胃功能虚弱怯弱，寒邪容易侵袭。如果在未满月的时间内，饮用冷水或吹受风寒，病邪会乘虚侵入并停留在盲膜（腹腔内包裹脏腑的薄膜组织），散布于腹部和胁肋部，因此出现阵发性的腹痛，或者疼痛像被锥子、刀子刺割一样。如果病邪流入大肠，导致水谷无法消化，出现剧烈腹泻、肠鸣音亢进，或者排泄物中带有红色和白色黏液，伴有胁肋部胀满感，应当立即服用调中汤，可以立刻痊愈。如果医生误认为是积滞而采用攻下法治疗，灾祸将接踵而至，务必谨慎，务必谨慎。
薛立斋说：产后发生的泻痢，可能是因为饮食损伤了脾土，或者是脾土虚弱不能消化食物，应当仔细辨证后进行治疗。如果是米食所伤，使用六君子汤加入谷芽；如果是面食所伤，使用六君子汤加入麦芽；如果是肉食所伤，使用六君子汤加入山楂、神曲。凡是兼有呕吐症状的，加入藿香；如果兼有吞酸或呕吐，用前面的药物送服越鞠丸；如果是肝木克制脾土（肝气犯胃），使用六君子汤加入柴胡、炮姜；如果是寒水反侮脾土（肾寒侵脾），使用钱氏益黄散；久泻导致元气下陷的，使用补中益气汤及四神丸；命门火衰不能温煦脾土的，使用八味丸以补益脾土之母（补肾阳）；如果小便涩滞不畅，肢体逐渐浮肿，或者兼有气喘咳嗽，使用金匮肾气丸。

Postpartum, the stomach and intestines are weak and fragile, making them susceptible to invasion by cold pathogens. If one consumes cold drinks or is exposed to wind before the completion of one month postpartum, the pathogen may take advantage of the deficiency to invade and remain in the epiploic appendages (membranous tissues wrapping the abdominal organs), dispersing into the abdomen and hypochondrium. Consequently, paroxysmal abdominal pain occurs, feeling as if pierced by awls or knives. If the pathogen flows into the large intestine, causing food and fluids to remain undigested, it leads to profuse diarrhea, borborygmus (intestinal rumbling), or the passage of red and white mucus, accompanied by distension in the hypochondrium. In such cases, Tiaozhong Decoction should be taken immediately for a prompt recovery. If physicians mistakenly attribute these symptoms to food stagnation and employ purgative methods, disaster will follow swiftly; caution is paramount, caution is paramount.
Xue Lizhai stated: Diarrhea and dysentery occurring postpartum may result from dietary injury to the Spleen Earth, or from Spleen Earth deficiency failing to digest food. Treatment must be based on careful differentiation. If injured by rice consumption, Liu Jun Zi Tang (Six Gentlemen Decoction) with Gu Ya (Sprouted Rice) should be used; if injured by wheat products, Liu Jun Zi Tang with Mai Ya (Sprouted Wheat) should be used; if injured by meat consumption, Liu Jun Zi Tang with Shan Zha (Crataegus Fruit) and Shen Qu (Medicated Leaven) should be used. For cases complicated by vomiting, Huo Xiang (Patchouli Herb) should be added. If acid regurgitation or vomiting is present, the aforementioned herbs should be taken with Yue Ju Wan (Yueju Pill). In cases where Liver Wood overacts on Spleen Earth (Liver Qi invading the Stomach), Liu Jun Zi Tang with Chai Hu (Bupleurum Root) and Pao Jiang (Prepared Ginger) should be used. In cases where Cold Water counter-acts Spleen Earth (Kidney Cold invading the Spleen), Qian Shi Yi Huang San (Qianshi's Yellow Protecting Powder) should be used. For prolonged diarrhea leading to sinking of Yuan Qi (Original Qi), Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) and Si Shen Wan (Four Spirits Pill) should be used. For Ming Men Fire Deficiency failing to warm Spleen Earth, Ba Wei Wan (Eight-Ingredient Pill) should be used to tonify the mother of Spleen Earth (tonify Kidney Yang). If urinary difficulty and gradual swelling of the limbs occur, possibly accompanied by wheezing and coughing, Jin Gui Shen Qi Wan (Golden Cabinet Kidney Qi Pill) should be used.
Deqi San (Miraculous Odd Powder)
Treats postpartum residual blood infiltrating the large intestine, manifesting as uncontrollable profuse diarrhea with green, white, or black stools.
Take four or five spikes of large Jing Jie (Schizonepeta Spike), burn them to ash in a small cup, ensuring no oil or fire contamination. Add a small amount of She Xiang (Musk), grind together, and take with decoction, divided into three doses. Although this prescription is mild, it can treat serious conditions.
Xiang Fu Shao Yao Tang (Cyperi and Peony Decoction)
Treats postpartum dysentery.
Dang Gui (Angelica Sinensis Root), Chuan Xiong (Ligusticum Rhizome), Shao Yao (Peony Root), Xiang Fu (Cyperus Rhizome), Chen Pi (Citrus Peel), Fu Ling (Poria), Bai Zhu (Atractylodes Macrocephala Rhizome) (each 1 qian), Sha Ren (Amomum Fruit) (6 fen), Gan Cao (Licorice Root) (5 fen), Ze Xie (Alisma Rhizome) (5 fen), Mu Xiang (Aucklandia Root) (3 fen).
Decoct in water and take orally. If abdominal pain is present, double the dosage of Shao Yao and add Huang Lian (Coptis Rhizome) 8 fen.
Xiang Lian Wan (Cyperi and Coptis Pill)
Effectively treats all types of diarrhea and dysentery.
Huang Lian (Coptis Rhizome) (purified, 12 liang), Wu Zhu Yu (Evodia Fruit) (remove stems and branches, 10 liang).
Mix the two ingredients with hot water, place in a porcelain vessel, and stew in a hot water bath for one day. Stir-fry together until Huang Lian turns purple-yellow. Remove Wu Zhu Yu, retaining only Huang Lian, and grind into powder. For every 4 liang of powder, add 1 liang of Mu Xiang powder. Use light vinegar and millet drink as binders to form pills the size of tung tree seeds. Take 30–40 pills per dose with boiling water. For chronic dysentery with sinking of Middle Qi, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction).
Tiaozhong Tang (Regulate the Middle Decoction)
Treats profuse diarrhea due to deficiency-cold postpartum.
Gao Liang Jiang (Galangal Rhizome), Dang Gui (Angelica Sinensis Root), Gui Xin (Cinnamon Twig Heart), Shao Yao (Peony Root), Chuan Xiong (Ligusticum Rhizome) (each 1 liang), Fu Zi (Prepared Aconite Lateral Root), Gan Cao (Licorice Root) (each 0.5 liang).
