汤氏说：小儿热泻的症状，是大便颜色黄中带红，有时带有泡沫，这是因为脏腑中有积滞。原因可能是乳母喜欢饮酒，或嗜食热性食物，或是婴儿出生时受湿邪侵袭蕴结化热。如果医生不明辨病情，仅仅使用豆蔻、诃子等药物服用，就像用水浇在石头上一样（无效），既不认识证候，所以不能辨别寒热，用药方法也不得当，怎么能取得疗效呢？此证应当以小便赤少、口干烦躁作为验证标准。治疗方法应当使用钱乙的白术散，去掉木香来服用；或者五苓散（若伴有惊风症状，去掉桂枝也可以服用）。如果热势严重，使用四逆散、大柴胡汤（均出自伤寒论）去掉大黄，服用后效果显著。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，有呕吐症状的加半夏。又有挟热泻痢且小便涩痛、颜色深红的情况，用加减四顺清凉饮（治疗里热）来治疗，即可停止。
薛氏说：右腮颜色发红，喜饮冷水，这是胃经实热，使用泻黄散（治疗脾热）。怕冷喜热，这是胃经虚热，使用白术散（治疗口渴）。右腮及额头都发红，这是心脾俱热，使用泻黄散加上炒黑的黄连。如果左颊和右腮都发红，这是肝火乘袭脾土，使用四君子汤（治疗吐泻）加柴胡。如果婴儿突然因乳食损伤，使用保和丸（治疗宿食）。乳母尤其应当忌口浓味食物，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，初起病而有热的，是邪气盛则实证；最终变为寒的，是正气夺则虚证；久病而有热的，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：治疗下利并伴有头痛胸满、口苦咽干，或往来寒热而呕吐，脉象浮大而弦的，或协热下利的情况。
药材：黄芩（一两半）、芍药、甘草（炙，各一两）。
制法：以上药材切碎成散剂。每次服用三钱，用一个枣子，水一盏，煎至七分，去渣温服。呕吐者，加半夏一两二钱半，生姜同煎。
〔张涣〕清胃散：治疗挟热泄利。
药材：川楝子、黄柏（微焙炙）、当归（洗，焙干）、地榆（炙）、黄连（去须炒，各半两）。
制法：以上药材捣碎，过筛为细末。每次服用一钱，水八分，煎至四分，去渣温服，在吃乳食之前服用。
香连丸
药材：黄连（姜汁拌炒，二两）、木香（煨，半两）。
制法：以上药材研为末。用陈米饭做丸，如绿豆大小。米汤送服一二十丸，也可以配合六一散调服。
Mr. Tang stated: In pediatric hot diarrhea (Hot Diarrhea), the stool is yellow with a reddish hue, sometimes containing froth. This condition arises from accumulation within the zang-fu organs. Causes may include the nursing mother's preference for alcohol or heat-inducing foods, or the infant contracting dampness at birth which transforms into heat. If physicians fail to understand the pathology and merely administer cardamom (Doukou) and chebula (Hezi), it is as ineffective as pouring water on stone. Since they do not recognize the syndrome, they cannot differentiate between cold and heat, and their therapeutic methods are inappropriate; how can they expect efficacy? This syndrome should be verified by signs such as scanty dark urine, dry mouth, and irritability. The treatment should employ Qian Yi's Baizhu San (Atractylodes Macrocephala Decoction) with Xiangru removed. Alternatively, Wuling San (Five-Ingredient Poria Decoction) may be used (if accompanied by fright, Guizhi may be omitted). For severe heat, Sini San (Frigid Extremities Powder) or Daxiehu Tang (Major Bupleurum Decoction) [both from Shanghan Lun] with Dahuang removed are effective. Additionally, Huanglian Wan (Coptis Pill) [for Gan malnutrition] is also suitable. Tiaozhong Tang (Regulate Middle Decoction) [for dysentery] with Dahuang removed, plus Huanglian and Zhike, is indicated. For diarrhea complicated by heat, specifically Taiyang and Shaoyang combined disease presenting with spontaneous diarrhea, Huangqin Tang (Scutellaria Decoction) should be given; if vomiting occurs, Banxia is added. For dysentery with heat complication characterized by difficult, dark red urination, Jiajian Sishun Qingliang Yin (Modified Four-Compliance Cooling Drink) [for interior heat] is used to stop the symptoms.
Mr. Xue stated: Redness of the right cheek with a desire for cold drinks indicates excess heat in the Stomach meridian, treated with Xiehuang San (Drain Yellow Powder) [for Spleen heat]. Aversion to cold and preference for warmth indicates deficiency heat in the Stomach meridian, treated with Baizhu San [for thirst]. Redness of both the right cheek and forehead indicates heat in the Heart and Spleen, treated with Xiehuang San plus stir-fried black Huanglian. Redness of both the left cheek and right cheek indicates Liver fire invading the Spleen earth, treated with Sijunzi Tang (Four Gentlemen Decoction) [for vomiting and diarrhea] plus Chaihu. If an infant suffers sudden injury from milk or food, Baohe Wan (Preserve Harmony Pill) [for retained food] is used. The nursing mother must strictly avoid rich flavors and regulate her diet. If the mother suffers from food stagnation causing infant vomiting and diarrhea, the mother should be treated. Generally, initial illness with heat indicates excess due to pathogenic qi dominance; eventual transformation into cold indicates deficiency due to depletion of true qi; prolonged illness with heat indicates true interior cold with false exterior heat. Prolonged diarrhea leading to deficiency-cold of Yuan Qi should be treated according to the aforementioned syndromes.
