婴儿初生，百日内，觉口冷腹痛，身起寒栗，时发战栗，曲足握拳，昼夜啼哭不
已，或口噤不开，名曰胎寒。其证，在胎时母因腹痛而致产，经云∶胎寒多腹痛。
亦有产妇喜啖甘肥生冷时果，或胎前外感风寒暑湿，治以凉药，内伤胎气，则生后
昏昏多睡，间或 乳泻白，若不早治，必成慢惊、慢脾。凡有此候，宜以冲和饮、

证，但无口冷寒战，名曰脏寒。其疾夜重日轻，腹痛肠鸣，泄泻清水，间有不泄者，
此证亦在百日内有之，皆因临产在地稍久，冷气侵逼，或以凉水参汤洗儿，或断脐

婴儿出生后一百天内，如果感觉口部发冷、腹部疼痛，身体出现寒战发抖，时常发生颤抖，双腿蜷曲、双手握拳，昼夜不停地啼哭不止，或者牙关紧闭无法张开，这被称为胎寒。这种病症的成因，是在胎儿时期母亲因腹痛而分娩，医经中说：“胎寒多伴有腹痛。”也有因为产妇喜欢食用甘甜、油腻、生冷的水果，或在怀孕前外感风寒暑湿之邪，治疗时使用了寒凉药物，内伤胎气，导致婴儿出生后昏昏欲睡，偶尔吐出乳块或大便泄泻白色稀便，如果不尽早治疗，必定会演变成慢惊风或慢脾风。凡是出现这些症状的，适宜使用冲和饮、当归散合方，用水煨姜煎服，使患儿轻微腹泻；腹泻停止后，改用匀气散调理补益；待腹泻止住、气息调匀、神志安宁、疼痛缓解、手足舒展后，再使用参苓白术散来养胃气，用白芍药汤去除体内的寒湿。乳母应当节制生冷冰冻的饮食饮料，这样才容易痊愈。又有另一种情况：手足稍冷，嘴唇面部微微发青，额头出汗，不顾吃奶进食，到了夜晚啼哭较多，颇似前面的证候，但没有口冷和寒战的症状，这称为脏寒。这种疾病夜间加重、白天减轻，伴有腹痛肠鸣、泄泻清水，间或有不泄泻的情况，此证也出现在出生百日内，都是因为临产时在地面停留时间稍久，冷气侵袭逼迫，或者用凉水参汤给婴儿洗澡，或者断脐带剪得太短，且结扎不紧密，被寒气所伤所致。适宜使用白芍药汤及冲和饮加盐炒小茴香、吴茱萸，用水姜煎服，并让乳母同时服用。（汤氏认为）小儿在胎中就有寒，出生后不能妥善护理，再次受风，其表现为面色青白，四肢逆冷，手足颤动，牙关紧闭无法张开，这是胎寒的缘故，或者是寒气乘虚侵入脏腑，引起腹痛盘肠内吊（治法详见“寒腹痛”条）。

Within one hundred days after birth, if the infant feels cold in the mouth and abdominal pain, experiences shivering and trembling of the body, frequently trembles, curls the legs and clenches the fists, cries incessantly day and night, or has a locked jaw that cannot open, this is named Tai Han (Fetal Cold). The etiology of this syndrome involves the mother experiencing abdominal pain during delivery while the fetus was still in the womb; as stated in the medical classics: "Tai Han is often accompanied by abdominal pain." It may also result from the mother's preference for consuming sweet, greasy, raw, or cold fruits, or from external contraction of Wind-Cold, Summer-Heat, and Dampness prior to pregnancy, treated with cooling medicines that internally injure the fetal Qi. Consequently, after birth, the infant becomes lethargic and sleepy, occasionally vomiting undigested milk or passing white loose stools. If not treated early, it will inevitably develop into Slow Convulsion (Man Jing Feng) or Slow Spleen Wind (Man Pi Feng). For such presentations, Chonghe Yin (Harmonizing Decoction) and Danggui San (Angelica Powder) should be combined and decocted with water-warmed ginger to induce mild diarrhea. Once diarrhea ceases, Yunqi San (Qi-Regulating Powder) should be administered to regulate and tonify. When diarrhea stops, Qi harmonizes, spirit calms, pain subsides, and limbs extend freely, Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) is used to nourish Stomach Qi, followed by Baishaoyao Tang (White Peony Decoction) to dispel Cold-Dampness. The nursing mother should abstain from raw, cold, and frozen foods and beverages to facilitate recovery. Another condition presents with slightly cold hands and feet, slight blueness of the lips and face, sweating on the forehead, refusal to nurse or eat, and increased crying at night, resembling the previous syndrome but lacking cold mouth and chills; this is named Zang Han (Visceral Cold). This disease is worse at night and lighter during the day, accompanied by abdominal pain, borborygmus, and watery diarrhea, sometimes without diarrhea. This syndrome also occurs within the first hundred days, caused by prolonged exposure to cold air during delivery, bathing the infant with cold water ginseng soup, cutting the umbilical cord too short, or inadequate ligation, allowing Cold pathogen to invade. Bai Shaoyao Tang (White Peony Decoction) and Chonghe Yin (Harmonizing Decoction) added with salt-fried Huixiang (Fennel Fruit) and Zhuyu (Evodia Fruit), decocted with water ginger, are indicated, and the nursing mother should take them concurrently. [Tang Shi] states that infants with Cold in the womb who suffer further Wind injury due to improper care after birth present with blue-white complexion, cold extremities, trembling of hands and feet, and locked jaw, which is due to Tai Han (Fetal Cold); alternatively, Cold may enter the viscera through deficiency, causing abdominal pain and intestinal twisting (see "Cold Abdominal Pain" section for treatment methods).
