钱仲阳曰∶寒吐者，由乳母当风取凉，或风寒客于乳房，其症面目胀，额汗出，脉沉迟微，
寒气停于胃，故胃不纳而吐出也。哕逆者，由胃气虚甚，过服克伐，使清气不升，浊气不降
，以致气不宣通而作也。风寒在胃者，用理中丸，次服酿乳法。若呕吐清涎夹乳，小便清利
，用大安丸。若因乳母食浓味，用东垣清胃散。若乳母饮醇酒，用葛花解醒汤；饮烧酒，服
冷米醋三五杯。乳母食生冷而致者，用五味异功散。乳母停食者，母服大安丸，子服异功散
。乳母劳役者，子母俱服补中益气汤。乳母怒动肝火者，用加味逍遥散。乳母郁怒伤脾者，
用归脾汤
，仍参热吐霍乱治之。

钱仲阳说：寒吐，是由于乳母在风中取凉，或者风寒邪气客居于乳房所致。其症状表现为面目肿胀，额头出汗，脉象沉迟而微弱。寒气停滞于胃中，导致胃不能受纳食物，从而引起呕吐。哕逆（呃逆），是由于胃气极度虚弱，过度服用攻伐药物，使得清气不能上升，浊气不能下降，从而导致气机宣通受阻而引发。对于风寒在胃的情况，使用理中丸，随后采用酿乳法。如果呕吐清稀涎沫夹杂乳汁，小便清长通畅，使用大安丸。如果是因乳母食用浓味食物引起，使用东垣清胃散。如果乳母饮用烈性酒，使用葛花解醒汤；如果饮用烧酒，则服用冷米醋三至五杯。如果是因乳母食用生冷食物导致，使用五味异功散。如果是乳母饮食停滞导致，母亲服用大安丸，婴儿服用异功散。如果是乳母劳累过度导致，母子共同服用补中益气汤。如果是乳母愤怒导致肝火亢盛，使用加味逍遥散。如果是乳母忧郁愤怒损伤脾脏，使用归脾汤，并参照热吐和霍乱的治法进行调理。
治疗案例：
一个小孩因为食积腹痛，服用疏导药物后痊愈。后来再次食积，又使用前药，出现寒热交替、食欲不振、腹胀且肛门坠胀感，大便次数多但量少，这是脾气再次受伤而下陷的表现。先用异功散加入升麻数剂，肛门坠胀感逐渐好转，再用当归痊愈。后来因为乳母愤怒，导致小孩出现寒热、抽搐、呕吐，用六君子汤、柴胡、山栀治疗乳母，同时给婴儿灌服，母子均痊愈。
一个小孩因为乳母感冒风寒发热，婴儿患呕吐，身上出现红色晕斑，使用东垣人参安胃散而痊愈；后来又出现咬牙、抽搐，呕吐酸腐食物，等待呕吐停止后自然安宁。
一个小孩时常呕吐乳食，诊察其母亲有忧郁愤怒的症状，使用加味归脾汤、加味逍遥散治疗而痊愈。
一个七岁小孩，身体消瘦兼有呕吐，进食少、发热、面色黄，我认为这是脾脏受伤，使用六君子汤、煨姜两剂，饮食进益，去掉生姜，又服数剂而痊愈。
一个小孩呕吐乳汁，大便气味臭秽，眼睛目光迟缓，是因为乳母性交后喂奶所致，使用六君子汤、木香、藿香治疗而安定。
一个小孩呕吐乳汁不进食，手足抽搐，痰涎上涌，手足指头冰冷，额头发黑嘴唇青紫，这是肾水克制心火的表现，使用五味异功散加入木香、炮姜，顿然痊愈；去掉生姜，又服数剂而痊愈。
一个小孩不时干呕，不吃奶，腹部膨隆，这是脾胃虚弱即将形成疳证的表现，使用四味肥儿丸治疗疳证，四君子汤健运中焦而痊愈。后来伤食，呕吐腹泻完谷不化，气行困倦疲惫，四肢轻微抽搐，我说暂且不要用药，第二天呕吐停止，只是抽搐且泻下青黄色粪便，这是脾土虚弱而肝木亢盛的表现，使用六君子汤、钩藤钩而痊愈。

清胃散
Qian Zhongyang stated: Cold vomiting arises from the wet nurse cooling off in the wind or from wind-cold pathogenic factors lodging in the breasts. The symptoms include swelling of the face and eyes, sweating on the forehead, and a deep, slow, and faint pulse. Cold qi stagnates in the Stomach, causing it to fail to receive food, leading to vomiting. Hiccups (Yue Ni) arise from extreme deficiency of Stomach Qi, excessive use of purgative drugs, which prevents Clear Qi from ascending and Turbid Qi from descending, resulting in impaired circulation of Qi. For cases where wind-cold is in the Stomach, Lizhong Wan (Regulate the Middle Pill) is used, followed by the Nurturing Milk Method. If clear saliva mixed with milk is vomited, and urination is clear and free, Da'an Wan (Great Peace Pill) is used. If caused by the wet nurse consuming rich flavors, Dongyuan Qingwei San (Stomach-Clearing Powder by Dongyuan) is used. If the wet nurse drinks strong wine, Gehua Jie Xing Tang (Pueraria Flower Decoction for Resolving Intoxication) is used; if she drinks distilled spirits, cold rice vinegar three to five cups is taken. If caused by the wet nurse consuming raw and cold foods, Wuwei Yigong San (Five-Ingredient Extraordinary Merit Powder) is used. If caused by food stagnation in the wet nurse, the mother takes Da'an Wan, and the infant takes Yigong San. If caused by the wet nurse's overwork, both mother and child take Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). If caused by the wet nurse's anger stirring Liver Fire, Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder) is used. If caused by the wet nurse's depression and anger injuring the Spleen, Guipi Tang (Restore the Spleen Decoction) is used, and treatment should also refer to that for heat vomiting and cholera-like disease.
Clinical Cases:
An infant suffered from abdominal pain due to food stagnation and recovered after taking promoting digestion drugs. Later, food stagnation recurred, and the same drugs were used again, resulting in alternating chills and fever, loss of appetite, abdominal distension with a sensation of heaviness in the rectum, and frequent but scanty stools. This indicated that the Spleen Qi was injured again and sinking. Initially, Yigong San with added Shengma (Cimicifugae Rhizoma) was administered for several doses, alleviating the rectal heaviness gradually. Subsequently, Danggui (Angelicae Sinensis Radix) cured the condition. Later, due to the wet nurse's anger, the infant developed chills, fever, convulsions, and vomiting. Liu Jun Zi Tang (Six Gentlemen Decoction), Chaihu (Bupleuri Radix), and Zhizi (Gardeniae Fructus) were used to treat the mother, while the infant was also fed the medicine, resulting in recovery for both.
An infant suffered from vomiting because the wet nurse had a cold with fever due to wind-cold invasion, and the infant developed red rashes on the body. Dongyuan Renshen Anwei San (Dongyuan's Ginseng Stomach-Calming Powder) cured the condition. Later, teeth grinding and convulsions occurred, accompanied by vomiting of sour and putrid matter; the infant calmed down naturally after the vomiting stopped.
An infant frequently vomited milk and food. Examination revealed the mother had symptoms of depression and anger. Jiawei Guipi Wan (Modified Restore the Spleen Pills) and Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder) cured the condition.
A seven-year-old child was emaciated and vomiting, with poor appetite, fever, and sallow complexion. I diagnosed this as injury to the Spleen organ. Liu Jun Zi Tang (Six Gentlemen Decoction) with Wei Jiang (Roasted Ginger) for two doses improved food intake. After removing the ginger, several more doses cured the condition.
An infant vomited milk, had foul-smelling stools, and slow eye movements. This was caused by breastfeeding immediately after sexual intercourse with the mother. Liu Jun Zi Tang (Six Gentlemen Decoction) with Muxiang (Aucklandiae Radix) and Huoxiang (Pogostemonis Herba) brought relief.
An infant vomited milk, refused food, had convulsions of hands and feet, surging phlegm-saliva, cold fingers and toes, black forehead, and blue lips. This indicated Kidney Water overcoming Heart Fire. Wuwei Yigong San (Five-Ingredient Extraordinary Merit Powder) with added Muxiang (Aucklandiae Radix) and Pao Jiang (Prepared Ginger) cured it instantly. After removing the ginger, several more doses completed the cure.
An infant occasionally dry heaved, refused milk, and had a distended abdomen. This indicated Spleen and Stomach deficiency progressing toward Infantile Malnutrition (Gan Syndrome). Siwei Fei'er Wan (Four-Ingredient Fattening Infant Pill) was used to treat Gan Syndrome, and Sijun Zi Tang (Four Gentlemen Decoction) strengthened the Middle Jiao, leading to recovery. Later, food injury caused vomiting and diarrhea of undigested food, with lethargy and slight convulsions of the limbs. I advised against medication temporarily. The next day, vomiting stopped, but convulsions persisted with greenish-yellow diarrhea. This indicated Spleen Earth deficiency and Liver Wood excess. Liu Jun Zi Tang (Six Gentlemen Decoction) with Goutenggou (Uncariae Ramulus cum Uncis) cured the condition.
Nurturing Milk Method: Treats infants with fetal heat syndrome. The wet nurse should take this formula. Do not abruptly use cold-natured drugs, as they may damage the Spleen and Stomach. Adding vomiting would lead to serious complications.
