汤氏说：小儿热泻，表现为大便色黄且带赤色，或伴有泡沫，这是由于脏腑内有积滞所致。原因可能是乳母喜好饮酒，或嗜食热性食物，或者是婴儿出生时感受湿邪蕴结化热。医生如果不明白这些道理，仅仅使用豆蔻、诃子等药物服用，就像用水浇在石头上一样（无法降温/无效），既不认识证候，因此不辨别寒热，用药又不得法，怎么能取得疗效呢？此证应当以小便短赤、口干烦躁作为验证标准。治疗方法应当使用钱乙的白术散，去掉木香后服用；或者使用五苓散（若受惊也可去掉桂枝服用）。如果热势严重，使用四逆散、大柴胡汤（均出自《伤寒论》）并去掉大黄，服用效果显著。另外使用黄连丸（治疗疳积）等方剂，也很好。调中汤（治疗痢疾）去掉大黄，加入黄连和枳壳。如果是夹热而泻，属于太阳与少阳合病自下利的情况，给予黄芩汤，呕吐的加半夏。又有挟热泻痢且小便涩痛、颜色深红的，用加减四顺清凉饮（清里热）治疗，即可停止。
薛氏说：右腮发红，喜饮冷水，是胃经实热，用泻黄散（治疗脾热）。怕冷喜热，是胃经虚热，用白术散（治疗口渴）。右腮及额头都发红，是心脾有郁热，用泻黄散加炒黑的黄连。如果左颊和右腮都发红，是肝火乘袭脾土，用四君子汤（治疗吐泻）加柴胡。如果婴儿突然伤于乳食，用保和丸（治疗宿食）。乳母尤其应当忌食浓味厚腻之物，节制饮食。如果乳母因停食受伤，导致婴儿出现吐泻等疾病，应当治疗母亲。大抵来说，初起病即发热的，是邪气盛则实证；最终变为寒证的，是正气夺则虚证；久病而发热的，是内真寒而外假热。久泻导致元气虚寒的，应当参考前面的证候进行治疗。
黄芩汤：治疗下利且头痛胸满，口苦咽干，或往来寒热且呕吐，脉象浮大而弦的，或协热下利的。
黄芩（一两半）、芍药、甘草（炙，各一两）。
以上切碎成散剂。每次服用三钱，大枣一个，水一盏，煎至七分，去渣温服。呕吐的，加半夏一两二钱半，生姜同煎。
〔张涣〕清胃散：治疗挟热泄利。
川楝子、黄柏（微焙炙）、当归（洗，焙干）、地榆（炙）、黄连（去须炒，各半两）。
以上捣碎，过筛为细末。每次服用一钱，水八分，煎至四分，去渣温服，在吃乳食之前。
香连丸
黄连（姜汁拌炒，二两）、木香（煨，半两）。
以上研为细末。用陈米饭做丸，如绿豆大小。米汤送服一二十丸，也可以配合调服六一散。
Tang Shi stated: In pediatric heat diarrhea, the stool is yellow and reddish, possibly with froth, caused by accumulation within the zang-fu organs. This may result from the nursing mother's preference for alcohol or hot-natured foods, or from the infant contracting dampness at birth which transforms into heat. If physicians do not understand this, but merely administer cardamom (Doukou) and chebula (Hezi), it is like pouring water on stone—ineffective. Since they fail to recognize the syndrome and thus cannot differentiate between cold and heat, and their medication methods are incorrect, how can they expect efficacy? For this syndrome, one should verify it by observing scanty dark urine, dry mouth, and irritability. The treatment method should employ Qian Yi's Baizhu San (Atractylodes Macrocephala Decoction), removing Xiang (Musk/Aucklandia depending on context, here likely referring to removing aromatic herbs if not specified, but text says "qu muxiang" remove Mu Xiang), or Wuling San (Five-Ingredient Powder with Poria). If there is fright, Guizhi (Cinnamon Twig) may be removed. If the heat is severe, Sini San (Frigid Extremities Powder) or Daxiehu Tang (Major Bupleurum Decoction) [both from Shanghan Lun], with Dahuang (Rhubarb) removed, should be used, showing remarkable efficacy. Additionally, Huanglian Wan (Coptis Pill) [for Gan malnutrition] and other formulas are also good. Tiaozhong Tang (Regulate Middle Decoction) [for dysentery], with Dahuang removed, plus Huanglian (Coptis) and Zhike (Aurantii Fructus). If diarrhea is accompanied by heat, belonging to the combined disease of Taiyang and Shaoyang presenting with spontaneous diarrhea, Huangqin Tang (Scutellaria Decoction) should be administered; add Banxia (Pinellia) if vomiting occurs. For heat-dysentery accompanied by difficult, dark red urination, Jiajian Sishun Qingliang Yin (Modified Smooth and Cooling Drink for Interior Heat) should be used to stop it.
Xue Shi stated: Redness on the right cheek with a desire for cold drinks indicates excess heat in the Stomach meridian, treated with Xiehuang San (Drain the Yellow Powder) [for Spleen heat]. Aversion to cold and preference for heat indicate deficiency heat in the Stomach meridian, treated with Baizhu San (Atractylodes Macrocephala Decoction) [for thirst]. Redness on both the right cheek and forehead indicates heat in the Heart and Spleen, treated with Xiehuang San (Drain the Yellow Powder) added with charred Huanglian (Coptis). If both the left cheek and right cheek are red, it indicates Liver fire invading Spleen earth, treated with Sijunzi Tang (Four Gentlemen Decoction) [for vomiting and diarrhea] added with Chaihu (Bupleurum). If the infant suddenly suffers from milk and food stagnation, Baohe Wan (Preserve Harmony Pill) [for retained food] should be used. The nursing mother must particularly avoid rich flavors and regulate her diet. If the mother suffers from food stagnation causing the infant's vomiting and diarrhea, the mother should be treated. Generally, initial fever indicates an excess syndrome due to pathogenic qi predominance; eventual transformation into cold indicates a deficiency syndrome due to depletion of true qi; prolonged illness with fever indicates true interior cold with false exterior heat. For prolonged diarrhea leading to deficiency-cold of Yuan Qi, refer to previous syndromes for treatment.
