钱仲阳云∶夏至后十日吐泻，身壮热，此热也。盖小儿脏腑十分中九分热也。或因伤热，
乳食不消，泻深
黄色，玉露散主之。大暑节后吐泻，身温以热，脏腑中六分热，四分冷也。呕吐，乳食前少，
服益黄散；食后多，服玉露散。立秋后七日吐泻，身温，脏腑中三分热，七分冷也。不能食乳，
多睡，闷乱，哽气，长出气，露睛唇白，多哕，欲大便，不渴，食前多，服益黄散；食后少，
服玉露散。秋分后吐泻身冷，无阳也。不能食乳，干哕，泻青水，当以补脾，益黄散主之。
郑氏云∶小儿吐泻，因外伤风冷，内伤乳食，或儿啼未定，气息未调，以乳饲之。气逆
于上则停滞胸膈，致令呕吐；气逆于下则伤脾胃，致令泄泻；上下气逆，吐泻俱作。凡小儿只吐
不泻者逆，其吐必有痰，发惊者，十无一生。若只泻不吐，或吐泻俱发者，日久不退，亦变
阴痫，治之当暂断其乳，轻者周时，重者三日，宜频与稀粥，服药速效，十全八九。或者不信
是言，以小儿藉乳为命，不肯暂断。然乳固不可断也，殊不知因乳所伤得之者，若再以所伤之乳
乳之，如抱薪救火。而暴吐泻者，脾胃俱虚，参术散加姜、枣去核煎服，以正胃气。大法吐泻

钱乙说：夏至后十日出现吐泻，身体高热，这是热证。因为小儿脏腑中十分中有九分是热的。如果是因为伤热，乳食不消化，泻下深黄色大便，用玉露散主治。大暑节后出现吐泻，身体温和而微热，脏腑中六分热、四分冷。呕吐，吃奶前量少，服用益黄散；吃奶后量多，服用玉露散。立秋后七日出现吐泻，身体温和，脏腑中三分热、七分冷。不能进食乳汁，嗜睡，烦闷混乱，噎气，长出气，眼睛半睁（露睛），嘴唇发白，频繁呃逆，想大便但不口渴，吃奶前症状多，服用益黄散；吃奶后症状少，服用玉露散。秋分后出现吐泻且身体发冷，这是无阳气的表现。不能进食乳汁，干呕，泻下青色水样便，应当补脾，用益黄散主治。
郑氏说：小儿吐泻，是因为外受风冷，内伤乳食，或者孩子啼哭未停，气息未调，就喂奶。气逆于上则停滞在胸膈，导致呕吐；气逆于下则损伤脾胃，导致泄泻；上下气机逆乱，吐泻同时发作。凡是小儿只吐不泻的属于逆证，其呕吐必有痰，并发惊风的，十例中没有一例能存活。如果只泻不吐，或者吐泻同时发作，日久不退，也会变成阴痫，治疗时应当暂时断绝乳汁，轻者一天，重者三天，宜频繁给予稀粥，服药见效快，治愈率八九成。有人不相信这番话，认为小儿依靠乳汁维持生命，不肯暂时断奶。然而乳汁固然不可完全断绝，殊不知因乳汁所伤而得的病，如果再喂这种致病的乳汁，就像抱着柴草去救火。对于突发吐泻的，脾胃都虚弱，用参术散加生姜、去核大枣煎服，以调和胃气。一般法则：吐泻伤冷的，用理中汤；伤热的，用五苓散。
理中汤：治疗脾胃不和，心腹攻痛，痰逆，恶心呕吐，心下虚烦，痞满，膈塞不通，饮食减少，短气羸困。温中逐水，止汗去湿。泄泻注下，水谷不分，腹中雷鸣，霍乱吐泻，手足厥冷一并治疗。

Qian Yi stated: Vomiting and diarrhea occurring ten days after the Summer Solstice, accompanied by high fever, is a heat syndrome. This is because in children, nine parts out of ten of their internal organs are characterized by heat. If caused by heat injury and indigestion of milk or food, resulting in dark yellow stools, Yulu San (Dew-Drop Powder) is the primary treatment. After the Great Heat solar term, vomiting and diarrhea occur with a warm but slightly hot body temperature; the internal organs exhibit six parts heat and four parts cold. For vomiting with less milk intake before feeding, Yihuang San (Yellow Benefit Powder) should be administered; for more milk intake after feeding, Yulu San is used. Seven days after the Beginning of Autumn, vomiting and diarrhea present with a warm body temperature; the internal organs show three parts heat and seven parts cold. The child cannot feed on milk, sleeps excessively, feels distressed and chaotic, experiences hiccupping, sighs deeply, has eyes that partially open (exposing the whites), white lips, frequent hiccups, desires to defecate but feels no thirst, and symptoms are more prominent before feeding (treat with Yihuang San) or less prominent after feeding (treat with Yulu San). After the Autumn Equinox, vomiting and diarrhea accompanied by cold body indicate a lack of Yang energy. Inability to feed, dry heaving, and passage of green watery stools require spleen tonification, primarily treated with Yihuang San.
Zheng stated: Pediatric vomiting and diarrhea result from external wind-cold invasion, internal injury from milk or food, or feeding while the infant is still crying and breathing unregulated. Qi reversing upward stagnates in the chest and diaphragm, causing vomiting; Qi reversing downward damages the spleen and stomach, causing diarrhea; when both upper and lower Qi reverse, vomiting and diarrhea occur simultaneously. Cases where infants only vomit without diarrhea are considered adverse prognoses; such vomiting involves phlegm, and if convulsions develop, none survive. Cases with only diarrhea without vomiting, or simultaneous vomiting and diarrhea that persist for a long time, may transform into Yin epilepsy. Treatment requires temporarily stopping breast milk; for mild cases, one day; for severe cases, three days. Frequent administration of thin rice gruel is recommended. Medication acts quickly, with an eight or nine out of ten cure rate. Some do not believe this advice, arguing that infants rely on milk for life and refuse temporary cessation. However, while milk cannot be completely stopped, it is unknown that if the illness was caused by milk injury, continuing to feed the offending milk is like carrying firewood to save a fire. For acute vomiting and diarrhea due to dual deficiency of spleen and stomach, Shenzhu San (Ginseng and Atractylodes Powder) with ginger and pitted dates decocted is used to regulate stomach Qi.
