大全云∶妊娠泄泻，或青或白，水谷不化，腹痛肠鸣，谓之洞泄；水谷不化，喜饮呕逆，谓
之协热下利，并以五苓散利小便，次以黄连阿胶丸，或三黄熟艾汤以安之。若泻黄有沫，肠
鸣腹痛，脉沉紧数，用戊己丸和之；嗳腐不食，胃脉沉紧，用感应丸下之，后调和脾胃；若风
冷，水谷不化如豆汁，用胃风汤；寒冷脐下阴冷，洞泄，用理中汤、治中汤；伏暑烦渴泻水，
用四苓散；伤湿泄泻，小便自利，用不换金正气散、胃苓汤。此四证之大略也。
薛氏曰∶泄泻若米食所伤，用六君加谷 ；面食所伤，用六君加麦 ；肉食所伤，用六
君加山楂；若兼寒热作呕，乃肝木侮脾土，用六君加柴胡、生姜，兼呕吐腹痛，手足逆冷，乃
寒水侮土，六君加姜、桂，不应，用钱氏益黄散；若元气下陷，发热作渴，肢体倦怠，用补中
益气汤；若泄泻色黄，乃脾土之真色，用六君加木香、肉果；若作呕不食，腹痛恶寒，乃脾
土虚寒，用六君加木香、姜、桂；若泻在五更侵晨，饮食少思，乃脾胃虚弱，五更服四神丸，日
间服白术散，如不应，或愈而复作，或饮食少思，急用八味丸，补命门火，以生脾土为善。
进士王征之内，怀妊泄泻，恶食作呕。余曰∶脾气伤也。其夫忧之，强进米饮，余谓饮亦
能伤胃，且不必强，俟脾胃醒，宿滞自化，饮食自进。不信，别用人参养胃汤饮之，吐水酸苦，
又欲投降火寒药。余曰∶若然则胃气益伤也。经云∶损其脾者，调其饮食，适其寒温。后不药果愈。

Quan Da records: During pregnancy, if diarrhea occurs with stools that are either green or white, containing undigested food and water, accompanied by abdominal pain and borborygmus, it is called Dong Xie (draining diarrhea); if there is undigested food and water, thirst with a desire to drink, and vomiting with reflux, it is called Xie Re Xia Li (diarrhea associated with heat); both conditions should first be treated with Wu Ling San (Five-Ingredient Powder with Poria) to promote urination and separate fluids, followed by Huang Lian E Jiao Wan (Coptis and Donkey-Hide Gelatin Pill) or San Huang Shu Ai Tang (Decoction of Three Yellows and Cooked Mugwort) to stabilize the condition. If the stool contains yellow foam, with borborygmus and abdominal pain, and the pulse is deep, tight, and rapid, use Wu Ji Wan (Wuji Pill) to harmonize; if there is belching with a putrid odor and an inability to eat, and the stomach pulse is deep and tight, use Gan Ying Wan (Miraculous Response Pill) to purge accumulation, followed by harmonizing the spleen and stomach; if caused by wind-cold, with undigested food resembling bean juice, use Wei Feng Tang (Stomach Wind Decoction); if there is coldness below the umbilicus and yin coldness, with draining diarrhea, use Li Zhong Tang (Regulate the Middle Decoction) or Zhi Zhong Tang (Treat the Middle Decoction); if caused by latent summerheat with irritability, thirst, and watery diarrhea, use Si Ling San (Four-Poria Powder); if caused by dampness injury with free urination, use Bu Huan Jin Zheng Qi San (Golden-Substitute Upright Qi Powder) or Wei Ling Tang (Stomach Poria Decoction). These are the general treatments for these four syndromes.
Xue Shi states: If diarrhea is caused by rice injury, use Liu Jun Zi Tang (Six-Gentleman Decoction) plus Gu Ya (Sprouted Grain); if caused by wheat injury, use Liu Jun Zi Tang plus Mai Ya (Sprouted Wheat); if caused by meat injury, use Liu Jun Zi Tang plus Shan Zha (Hawthorn Fruit); if accompanied by alternating chills and fever with vomiting, this is Liver Wood insulting Spleen Earth, treat with Liu Jun Zi Tang plus Chai Hu (Bupleurum Root) and Sheng Jiang (Fresh Ginger); if accompanied by vomiting, abdominal pain, and cold extremities, this is Cold Water insulting Earth, treat with Liu Jun Zi Tang plus Gan Jiang (Dried Ginger) and Rou Gui (Cinnamon Bark); if ineffective, use Qian Shi Yi Huang San (Qian's Yellow-Enhancing Powder); if Yuan Qi (Primal Qi) sinks, accompanied by fever, thirst, and limb fatigue, use Bu Zhong Yi Qi Tang (Decoction to Supplement the Middle and Augment the Qi); if the diarrhea is yellow in color, representing the true color of Spleen Earth, use Liu Jun Zi Tang plus Mu Xiang (Aucklandia Root) and Rou Dou Kou (Nutmeg); if accompanied by vomiting, anorexia, abdominal pain, and aversion to cold, this is deficiency-cold of Spleen Earth, use Liu Jun Zi Tang plus Mu Xiang, Gan Jiang, and Rou Gui; if diarrhea occurs at dawn (Wu Geng), with reduced appetite, this is deficiency of Spleen and Stomach, take Si Shen Wan (Four Spirits Pill) at dawn and Bai Zhu San (Atractylodes Powder) during the day; if ineffective, or if the disease recurs after remission, or if appetite remains poor, urgently use Ba Wei Wan (Eight-Ingredient Pill) to tonify Ming Men Fire (Fire of the Gate of Vitality) to generate Spleen Earth, which is the best approach.
The wife of Jinshi Wang Zhengzhi suffered from diarrhea and anorexia with vomiting during pregnancy. I said, "This is an injury to Spleen Qi." Her husband was worried and forced her to drink rice water. I told him, "Rice water can also damage Stomach Qi; do not force it. Wait for the Spleen and Stomach to awaken, and the retained stagnation will resolve naturally, restoring appetite." They did not believe me and used Ren Shen Yang Wei Tang (Ginseng Decoction to Nourish the Stomach) prescribed by another doctor. She vomited sour and bitter water and wanted to take fire-descending cold medicines. I said, "If so, Stomach Qi will be further damaged." The Classic says: "For those injured in the Spleen, regulate their diet and adapt to cold and warmth." Later, without medication, she recovered.
