早晨进食，傍晚呕吐，属于寒性呕吐。乳汁和食物不消化且气味不酸臭，四肢冰冷，面色和嘴唇发白，可用姜橘散或丁萸理中汤煎服治疗。
[注释]
寒性呕吐，都是因为小儿过量食用生冷食物，或者乳母在风中乘凉，导致寒气进入乳汁，小儿饮用后，就形成了冷吐的证候。其表现为早晨吃下的食物傍晚吐出，乳汁和食物不消化，吐出的东西没有酸臭味，四肢逆冷，面色和嘴唇颜色苍白。治疗应当温中止吐，胃中有轻微寒气的，用姜橘散主治；寒气严重的，用丁萸理中汤主治。

进食后立即呕吐，是因为胃热。口渴想喝冷水，呕吐酸水，身体发热，嘴唇红润，小便颜色深黄，加味温胆汤可以治愈。
[注释]
热性呕吐的证候，可能是因为小儿过量食用油炸烧烤的食物，或者乳母过量食用肥厚滋腻的食物，导致热邪积聚在胃中，于是造成食物吃下去就立刻呕吐出来，口渴想喝冷水，呕吐酸水，身体发热，嘴唇红润，小便颜色深红。治疗应当以清热为主，用加味温胆汤主治。

小儿泄泻必须辨认清楚，分为伤乳、停食、冷泻、热泻、惊泻。脏腑虚寒、脾虚导致的完谷不化（飧泻）和水样便（水泻），需要分别采用消导分利或温补的方法，治疗要精准。
[注释]
泄泻这一证候，多因脾脏被湿气浸淫，土气不能胜水湿而形成的。然而致病的根源各不相同，或者是乳食停滞不消化，或者是感受寒暑之气，或者是惊邪从外部触动，或者是脏腑受到寒冷侵袭，或者是脾虚导致的泄泻，更有完谷不化和水样便的证候。致病原因不同，调理治疗的方法也不同。医生详细辨证，或者采用消导分利，或者采用温补，根据证候施治，这样就不会出错了。

泄泻证门
Morning intake with evening vomiting indicates Cold Vomiting (Han Tu). The milk and food are undigested and lack a sour or foul odor; the limbs are cold, and the face and lips are pale. This can be treated with decoctions of Jiangju San (Ginger and Tangerine Peel Powder) or Dingyu Lizhong Tang (Clove and Evodia Decoction for Regulating the Middle).
[Note]
Cold Vomiting is caused by infants consuming excessive amounts of raw and cold foods, or by nursing mothers exposing themselves to wind and cooling off, allowing cold pathogenic factors to enter the breast milk. When the infant drinks this milk, it results in Cold Vomiting. The symptoms include vomiting ingested food in the evening after morning consumption, undigested milk and food, vomitus that is neither sour nor foul-smelling, cold extremities, and pale complexion and lips. Treatment should focus on warming the middle jiao and stopping vomiting. For mild stomach cold, Jiangju San is indicated; for severe cold, Dingyu Lizhong Tang is indicated.
(Jiangju San) Prepared Ginger (Paojiang) 1 qian, Chenpi (Aged Tangerine Peel) 1 liang, Zhi Gancao (Honey-fried Licorice Root) 1 qian. Grind the above into fine powder. Take 1 qian per dose, mixed with warm Jujube water.
(Lizhong Tang) See the formula under "Failure to Suckle," adding Dingxiang (Clove) and Wuzhuyu (Evodia Fruit).

Vomiting immediately after eating is due to Stomach Heat. Symptoms include thirst with a desire for cold drinks, vomiting of sour fluid, body heat, red lips, and dark urine. Jiawei Wendan Tang (Modified Phlegm-Resolving Decoction) can cure this.
[Note]
Heat Vomiting may result from infants overeating fried or roasted foods, or from nursing mothers consuming rich and heavy foods, leading to heat accumulation in the stomach. Consequently, food is vomited immediately upon ingestion. Symptoms include thirst with a desire for cold drinks, vomiting of sour fluid, fever, red lips, and dark red urine. Treatment should prioritize clearing heat, using Jiawei Wendan Tang as the primary formula.
(Jiawei Wendan Tang) Chenpi (Aged Tangerine Peel), Banxia (Pinellia Tuber, processed with ginger juice), Fuling (Poria), Maidong (Ophiopogon Root, heart removed), Zhishi (Immature Bitter Orange, bran-fried), Sheng Gancao (Raw Licorice Root), Zhuru (Bamboo Shavings), Huanglian (Coptis Rhizome, stir-fried with ginger juice). Decoct with Dengxincao (Juncus Effusus) and take orally.
(Verse Formula)
For Heat Vomiting, use Wendan Tang,
Chenpi, Banxia, and Fuling are good.
Maidong, Zhishi, and Raw Gancao,
With Zhuru and Huanglian, decocted well.

Infantile Diarrhea must be clearly differentiated into categories: Milk Injury, Food Stagnation, Cold Diarrhea, Heat Diarrhea, and Shock Diarrhea. For conditions involving organ coldness, Spleen deficiency, Sundry Diarrhea (Sun Xie, characterized by undigested food), and Water Diarrhea (Shui Xie, characterized by watery stools), treatments such as resolving stagnation/drainage or warming/tonifying should be applied precisely.
[Note]
Diarrhea is mostly caused by the Spleen being immersed in dampness, where Earth fails to control Water. However, the origins of disease vary: it may be due to stagnant milk and food that fail to digest, exposure to cold or summerheat pathogens, external shock pathogens, cold affecting the zang-organs, or Spleen deficiency causing diarrhea. There are also cases of Sundry Diarrhea and Water Diarrhea. Since the causes differ, the methods of regulation and treatment also differ. Physicians must differentiate carefully, applying either draining/resolving methods or warming/tonifying methods according to the specific syndrome, thus avoiding errors.
