巢氏曰∶小儿在胎，母食热毒之物，或热药，令儿生下体热面赤，眼闭口热，痰盛喘
急，大便不通，小便赤涩。多因胎中受热，或因误服温剂，致令热蓄于内，蒸胎气，固有此证。
若久而不治，则鹅口重舌，紫赤丹瘤，急惊风搐，皆由此而生也。
小儿初生有胎热证者，宜先以木通散煎与母服，使通于乳，令儿饮之，通心气解烦热，不可
求速效。乳母服药，渐次解热，百无一失。若以凉药攻之，必致呕吐也，变生大患。乳
母仍忌辛辣酒面浓味，庶易得安。

眼上出现赤色血脉，向下贯穿瞳孔。囟门突起，甚至凹陷成坑。鼻孔黑而干燥，腹部胀大且青筋暴露。眼睛多呈直视状态，眼球不能转动。指甲呈现青黑色，突然发出类似乌鸦的叫声。舌头伸出并脱出肛门（或指舌体松弛外翻），咬齿甚至咬人。呼吸急促如鱼口开合，啼哭却发不出声音。蛔虫一旦排出，必定是死证。此时即使迅速用药抢救，十个人中也救不活一个。

巢元方说：小儿在母胎中时，母亲食用了热毒之物，或服用了热性药物，导致婴儿出生后身体发热、面色红润、眼睑闭合、口内灼热、痰多气喘急促、大便不通、小便短赤涩痛。这大多是因为胎中受热，或者误服温补药剂，导致热邪蓄积于体内，蒸腾胎气，因此产生这种病症。如果长期不治疗，就会引发鹅口疮（口腔黏膜上的白色斑膜）、重舌（舌下肿起如再出一舌）、紫赤丹瘤（皮肤红肿如丹砂）、急惊风抽搐等症，都是由胎热引起的。
患有胎热证的小儿，应当先用木通散煎汤让乳母服用，使药力通过乳汁传递，让婴儿饮用，以疏通心气、解除烦热，不可追求速效。乳母服药后，热邪会逐渐消退，几乎不会失手。如果用寒凉药物直接攻伐婴儿，必然会导致呕吐，从而引发更大的祸患。乳母在此期间仍应忌食辛辣、酒类、面食及浓味食物，这样才容易痊愈。

The upper eyelids show red meridians extending downward to penetrate the pupil. The fontanelle protrudes, and in severe cases, becomes sunken into a pit. The nostrils are black and dry; the abdomen is distended with visible blue veins. The eyes are mostly fixed in a staring gaze, unable to rotate. The fingernails turn cyanotic-black, and the infant suddenly makes sounds resembling those of a crow. The tongue extends and may prolapse from the anus (or refers to flaccid tongue protrusion); the infant gnashes teeth and bites people. Breathing is rapid and labored like a fish opening its mouth, yet crying produces no sound. Once roundworms are expelled, death is certain. Even if medication is administered urgently for rescue, fewer than one in ten survives.
Heart disease manifests as darkening of the pupils; this is Kidney Water overcoming Heart Fire, leading to critical failure on Ren-Gui days (Water days). Liver disease manifests as blackening of the skin; this is Lung Metal overcoming Liver Wood, leading to critical failure on Geng-Xin days (Metal days). Spleen disease manifests as bluish lips; this is Liver Wood overcoming Spleen Earth, leading to critical failure on Jia-Yi days (Wood days). Lung disease manifests as swollen cheeks and reddened eyes; this is Heart Fire overcoming Lung Metal, leading to critical failure on Bing-Ding days (Fire days). Kidney disease manifests as facial edema and yellowish lips; this is Spleen Earth overcoming Kidney Water, leading to critical failure on Wu-Ji days (Earth days).
Chao Yuanfang stated: When a child is in the womb, if the mother consumes heat-toxic substances or takes heat-inducing medicines, the infant will be born with body heat, ruddy complexion, closed eyelids, hot mouth, excessive phlegm, panting and urgency, constipation, and scanty, painful urination. This is mostly due to heat accumulation in the fetus, or misadministration of warm tonics, causing heat to accumulate internally and steaming the fetal qi, thus producing this syndrome. If left untreated for a long time, it will give rise to conditions such as thrush (white plaques on oral mucosa), double tongue (swelling under the tongue resembling a second tongue), purple-red dan tumors (skin redness like cinnabar), and acute convulsive wind spasms, all originating from fetal heat.
For infants suffering from fetal heat syndrome, one should first administer Mutong San decoction to the nursing mother so that the medicinal properties pass through the breast milk for the infant to drink. This unblocks Heart Qi and resolves vexatious heat. One must not seek rapid effects. As the nursing mother takes the medicine, the heat will gradually dissipate, with almost no chance of failure. If cold-natured drugs are used to attack the infant directly, vomiting will inevitably occur, leading to major complications. The nursing mother must still avoid spicy, pungent, alcoholic, wheat-based foods, and rich flavors, so that recovery can be easily achieved.
