东垣云∶伤食则恶食，小儿食泻者，因饮食伤脾，脾气不能健运，故乳食不化而出。若嗳臭
吞酸，胸膈胀满，腹痛按之益痛者，虽作泻，而所停滞之物，尚未消也，用保和丸。腹痛按
之不痛者，乳食已消也，用异功散。脾气伤而未复，不思饮食者，用六君子汤；所伤生冷之
物及喜热者，并加木香、干姜。乳食已消，腹痛已止，泻尚未止者，脾失清升之气也，用补
中益气汤。余有别症，当参各门。
治验
一小儿泄泻不食，嗳腐酸气，用平胃散一服而泻止，又用五味异功散而饮食增。后复伤，吐

李东垣说：伤食会导致厌恶食物。小儿的食泻，是因为饮食损伤了脾胃，脾气不能正常运化，所以乳汁和食物无法消化而排出体外。如果出现嗳气有腐臭味、吞酸、胸膈胀满、腹痛且按压时疼痛加剧的情况，虽然正在腹泻，但停滞在体内的食物尚未消化，应使用保和丸。如果腹痛且按压时不痛，说明乳食已经消化，应使用异功散。如果脾气受伤但尚未恢复，没有食欲，应使用六君子汤；如果是因食用生冷之物或喜热者，并加入木香、干姜。如果乳食已经消化，腹痛已经停止，但腹泻仍未停止，这是脾脏失去了清阳上升之气，应使用补中益气汤。其余不同的症状，应当参考各章节内容。
治验记录：
有一个小儿泄泻且不进食，嗳气有腐臭酸味，服用一剂平胃散后腹泻停止，又服用五味异功散后饮食增加。后来再次伤食，出现呕吐、腹泻、气喘咳嗽，手指脚趾发冷，面色黄白。我认为这是脾虚不能生养肺脏，于是使用六君子汤加升麻、桔梗治疗而痊愈。
有一个小儿因伤食导致腹泻发热，服用寒凉药物后，发热加重并呕吐，这是胃经的虚热。先用四君子汤加升麻使呕吐停止，又用白术散调理而安定。
有一个小儿哺乳喂养不当，导致泄泻腹痛，自行用药攻下，反而加重了痰湿和抽搐。又服用化痰止搐的药物，导致痰湿抽搐更加严重，睡觉时眼睛半睁（露睛），手脚微微发冷。我认为这是脾胃已经虚弱又被重伤，于是使用异功散加木香、钩藤钩，母子同时服药，三天后痰湿抽搐停止，五天后腹泻腹痛消除。
有一个小儿因伤食导致腹泻、大便青色并发生抽搐，我认为这是肝木克制脾土，于是使用六君子汤、木香、钩藤钩治疗而痊愈。后来再次伤食腹痛，另用消食丸，出现嘴唇青紫、额头发黑，腹泻更加严重，这是脾气亏损，寒水反来克制脾土（水侮土），于是使用六君子汤、木香、干姜治疗而痊愈。
有一个小儿面色萎黄，因伤食导致腹泻，面色突然变白，气喘痰多涌出。我认为这是脾肺气虚下陷，治法应当升提补益。患者不信，另服清气化痰的药物，导致虚证蜂拥而起。我先用一剂补中益气汤，各种症状顿时消退，又用五味异功散治疗而痊愈。
有一个小儿泄泻，两手寸脉或短或伏。用补中益气汤治疗顿时痊愈。我见到患前症不服此药而病情危重的很多，可惜啊！
有一个小儿饮食后立即腹泻，先用六君子汤加升麻、神曲、山楂使腹泻停止，又用五味异功散加升麻治疗而痊愈。后来伤食，出现呕吐、腹泻、腹痛，用保和丸服用两剂，又用异功散，调理补益脾气而安定。
有一个小儿因伤食导致腹泻、腹胀，四肢浮肿，小便不利。先用五苓散加木香，十几天后各种症状逐渐消退。又以五味异功散为主方，佐以加减肾气丸。又过了十天，大小便调和，饮食逐渐增加，浮肿随即消退。最后用异功散调理而痊愈。
有一个十三岁的小儿，因伤食导致腹泻，服用克伐（攻伐）的药物，导致胸腹部膨胀，手脚都冷。我认为应当调补中气，患者不信，后来出现睡觉时眼睛半睁，嘴唇口角抽搐，于是使用六君子汤、木香、钩藤钩，服至四剂后抽搐顿时停止；再服一剂，饮食增加，用五味异功散加升麻、柴胡，膈间宽舒、腹泻停止而痊愈。

Li Dongyuan stated: Food stagnation leads to aversion to food. In children, diarrhea due to food stagnation occurs because dietary intake damages the spleen and stomach; the spleen qi fails to transport and transform normally, resulting in milk and food failing to digest and being expelled. If there is belching with a foul, rotten odor, acid regurgitation, distension and fullness in the chest and diaphragm, and abdominal pain that worsens upon pressure, although diarrhea is present, the stagnant food has not yet been digested; Bahe Wan (Harmony Preservation Pill) should be used. If abdominal pain does not worsen upon pressure, it indicates that the milk and food have already been digested; Yigong San (Extraordinary Efficacy Powder) should be used. If spleen qi is injured but has not yet recovered, and there is a lack of appetite, Liujunzi Tang (Six Gentlemen Decoction) should be used; if caused by consuming raw or cold foods or if the patient prefers heat, add Muxiang (Aucklandiae Radix) and Ganjiang (Zingiberis Rhizoma). If the milk and food have been digested, abdominal pain has ceased, but diarrhea persists, this is due to the spleen losing its clear yang ascending qi; Buzhong Yiqi Tang (Decoction to Supplement the Middle and Augment the Qi) should be used. For other varying symptoms, refer to the respective sections.
Clinical Cases:
A child presented with diarrhea and anorexia, with belching emitting a foul, sour odor. After one dose of Pingwei San (Calm the Stomach Powder), the diarrhea stopped. Subsequently, Wuyi Yigong San (Five-Gentleman Extraordinary Efficacy Powder) was administered, increasing appetite. Later, re-injury from food occurred, presenting with vomiting, diarrhea, wheezing, coughing, cold fingers and toes, and a sallow-white complexion. I reasoned that spleen deficiency failed to generate lung qi. The case was cured using Liujunzi Tang (Six Gentlemen Decoction) added with Shengma (Cimicifugae Rhizoma) and Jiegeng (Platycodonis Radix).
A child suffered from diarrhea and fever due to food stagnation. After taking cold-natured medicines, the fever intensified and vomiting ensued, indicating deficient heat in the stomach meridian. Si Junzi Tang (Four Gentlemen Decoction) added with Shengma (Cimicifugae Rhizoma) was first used to stop vomiting, followed by Baizhu San (Atractylodis Macrocephalae Powder) to stabilize the condition.
A child had improper breastfeeding habits, leading to diarrhea and abdominal pain. Self-medication with purgatives exacerbated phlegm and convulsions. Subsequent administration of phlegm-resolving and convulsion-stopping medicines worsened the phlegm and convulsions, accompanied by sleeping with eyes half-open (exposed pupils) and slightly cold extremities. I attributed this to severe injury of already deficient spleen and stomach qi. Yigong San (Extraordinary Efficacy Powder) added with Muxiang (Aucklandiae Radix) and Goutenggou (Uncariae Ramulus cum Uncis) was administered to both mother and child. Phlegm and convulsions ceased after three days, and diarrhea and abdominal pain resolved after five days.
A child presented with green stools and convulsions following food-induced diarrhea. I diagnosed liver wood overacting on spleen earth. The case was cured using Liujunzi Tang (Six Gentlemen Decoction), Muxiang (Aucklandiae Radix), and Goutenggou (Uncariae Ramulus cum Uncis). Later, recurrent food stagnation caused abdominal pain. Another prescription, Xiaoshi Wan (Digestive Aid Pill), was used, resulting in cyanotic lips, dark forehead, and worsening diarrhea. This indicated spleen qi depletion with cold water counter-acting to insult spleen earth (water insulting earth). The case was cured using Liujunzi Tang (Six Gentlemen Decoction), Muxiang (Aucklandiae Radix), and Ganjiang (Zingiberis Rhizoma).
A child with a sallow complexion presented with sudden pallor, wheezing, and abundant phlegm following food-induced diarrhea. I diagnosed sinking of spleen and lung qi deficiency, requiring lifting and tonification. The parents disbelieved and administered phlegm-clearing and qi-transforming medicines, causing multiple deficiency syndromes to arise. One dose of Buzhong Yiqi Tang (Decoction to Supplement the Middle and Augment the Qi) immediately alleviated all symptoms, followed by Wuyi Yigong San (Five-Gentleman Extraordinary Efficacy Powder) for recovery.
A child with diarrhea presented with short or hidden pulses at both cun positions. Buzhong Yiqi Tang (Decoction to Supplement the Middle and Augment the Qi) resulted in immediate cure. I observed many cases of prior symptoms becoming critical when this formula was not used; how regrettable!
A child experienced immediate diarrhea after eating. Liujunzi Tang (Six Gentlemen Decoction) added with Shengma (Cimicifugae Rhizoma), Shenqu (Massa Fermentata Medicinalis), and Shanzha (Crataegi Fructus) stopped the diarrhea. Wuyi Yigong San (Five-Gentleman Extraordinary Efficacy Powder) added with Shengma (Cimicifugae Rhizoma) ensured recovery. Later, food stagnation caused vomiting, diarrhea, and abdominal pain. Two doses of Bahe Wan (Harmony Preservation Pill) were given, followed by Yigong San (Extraordinary Efficacy Powder) to regulate and tonify spleen qi, stabilizing the condition.
A child presented with diarrhea, abdominal distension, limb edema, and dysuria due to food stagnation. Wuling San (Five-Ingredient Powder with Poria) added with Muxiang (Aucklandiae Radix) was used initially, with symptoms gradually receding over ten days. Wuyi Yigong San (Five-Gentleman Extraordinary Efficacy Powder) was then used as the main formula, assisted by Jiajian Shenqi Wan (Modified Kidney Qi Pill). After another ten days, bowel and bladder movements harmonized, diet improved, and edema subsided. The case was finally cured with Yigong San (Extraordinary Efficacy Powder) for regulation.
A thirteen-year-old child took purgative medicines for food-induced diarrhea, resulting in abdominal distension and cold extremities. I advised regulating and tonifying middle qi, but the advice was ignored. Later, sleeping with eyes half-open and lip/mouth twitching appeared. Liujunzi Tang (Six Gentlemen Decoction), Muxiang (Aucklandiae Radix), and Goutenggou (Uncariae Ramulus cum Uncis) were administered. Twitching ceased after four doses. After one more dose, diet improved. Wuyi Yigong San (Five-Gentleman Extraordinary Efficacy Powder) added with Shengma (Cimicifugae Rhizoma) and Chaihu (Bupleuri Radix) widened the diaphragm, stopped diarrhea, and cured the case.
