【薛己】小儿在母胎中，禀受阴阳五行之气，从而生成脏腑和肢体，依靠胎液来滋养。当元气充足时，自然分娩。在分娩之时，口中含着血块，啼哭一声发出后，随即咽下，导致毒邪潜伏于命门（人体生命活动的根本，此处指肾间动气）。遇到天行时气（流行性传染病邪气）引起的久热，或饮食停滞，或外感风寒，惊风发热等原因，就会引发疮疹。必须在婴儿尚未啼哭之前，用柔软的布包裹手指，挖去口中的血块，并用黄连、豆豉、朱蜜、甘草来解毒。即使后来出痘，病情也会较轻。
如果血块咽入后立即出现腹胀呕吐、呼吸短促、不能吃奶的症状，用茯苓丸治疗。但是黄连性寒，如果婴儿禀受母亲体内膏粱厚味积热者适宜服用；如果口味淡薄、胎气原本虚弱者又不宜使用。朱砂固然能解毒，但担心金石类药物镇坠伤正，不如只用少许牛黄，用蜂蜜调匀让婴儿吮吸为佳。世间多使用犀角解毒丸，对于胎气虚寒虚弱者，反而损伤脾胃的生气，甚至导致不育。
又有婴儿因为难产，或冒受风寒而处于垂危状态，切不可立即剪断脐带。应急忙烘烤棉絮，将婴儿抱在怀中保暖，迅速将胎衣放在火中煨烧，再用大纸捻在脐带上往来燎烤，使暖气进入腹部，片刻之后气息恢复，婴儿自然苏醒。尤其要禁止洗浴，恐怕腠理（皮肤纹理及汗孔）不紧密，元气发泄而外邪趁机侵袭。
婴儿刚产出胎，急忙用绵裹住手指，揩拭婴儿口中的舌上恶血秽露，这称为“玉衔”。如果啼声一发，恶血即入腹，会形成百病。另外查看舌下，如果连舌处有膜像石榴子一样，导致啼哭不出、声音不转，速用手指甲掐断它，或用苇叶刀割开它，微有血出，婴儿就能活。如果舌下出血较多，用烧过的乱发灰同少许猪脂调和涂抹。（《圣惠方》说：看齿根有两条黄筋，用苇刀割断，点猪乳效果佳。如果婴儿口难张开，先点猪乳。）婴儿上下唇与齿龈连接处，都有一条筋牵引，如果上唇筋紧，就会生“上炼”，下唇筋紧，就会生“下炼”。
上炼，头部生疮，或者眉间像癣状，瘙痒不止，又流黄水，所到之处生疮。下炼，起于腰背逐渐蔓延至四肢，病症同上。如果疾病严重不治疗，或者头面上下相通，经年不愈，又夭折或变成大病，这是唯独每天早晨拭口的缘故（意指若每日清晨拭口可预防此病）。
[Xue Ji] While in the womb, the infant receives the Qi of Yin and Yang and the Five Elements to generate the Zang-Fu organs and limbs, relying on amniotic fluid for nourishment. When the prenatal Qi is sufficient, natural birth occurs. At the time of delivery, the infant holds a blood clot in the mouth; upon crying, it is immediately swallowed, causing toxic pathogens to lie latent in the Mingmen (Gate of Life, referring to the vital energy between the kidneys). Upon encountering prolonged fever from epidemic pathogenic factors (Tianxing Shiqi), food stagnation, external contraction of wind-cold, or convulsions with fever, sores and rashes may erupt. It is urgent to use soft cloth wrapped around the finger to remove the blood before the infant cries, and to resolve the toxicity using Huanglian (Coptis Rhizome), Douchi (Fermented Soybean), Zhumi (Cinnabar Honey), and Gancao (Licorice Root). Even if smallpox later appears, the condition will be mild.
If immediate abdominal distension, vomiting, shortness of breath, and inability to nurse occur after swallowing, treat with Fuling Wan (Poria Pill). However, Huanglian is cold in nature; it is suitable for infants who have inherited maternal accumulation of heat from rich foods, but unsuitable for those with bland diets and weak prenatal Qi. Although Zhusha (Cinnabar) can detoxify, one must fear that mineral substances may suppress and damage the upright Qi; it is better to use a small amount of Niuhuang (Calculus Bovis), mixed with honey for the infant to suck. The world often uses Xijiao Jiedu Wan (Rhinoceros Horn Detoxification Pill), which, for infants with deficient and cold prenatal Qi, instead damages the generating Qi of the Spleen and Stomach, potentially leading to failure to thrive.
For infants in critical condition due to difficult labor or exposure to wind-cold, do not cut the umbilical cord immediately. Quickly warm cotton wadding, hold the infant close to warm them, rapidly place the placenta in fire to smolder, and use large paper twists to cauterize back and forth on the umbilical cord, allowing warm Qi to enter the abdomen. Within moments, the Qi recovers, and the infant revives naturally. Bathing is strictly prohibited, lest the Couli (skin pores and interstices) be loose, causing the Yuan Qi (Original Qi) to dissipate and allowing external pathogens to invade.
When an infant is newly born, quickly wrap a finger in cotton to wipe away the foul blood and impurities on the tongue and in the mouth, known as "Yu Xian" (Jade Holding). If the cry sounds once, the blood enters the abdomen, causing myriad diseases. Also examine under the tongue; if there is a membrane like a pomegranate seed connecting the tongue (Ankyloglossia), preventing crying or voice change, quickly pinch it off with fingernails or cut it with a reed knife. With slight bleeding, the infant survives. If bleeding from under the tongue is excessive, apply ash from burned disordered hair mixed with a little pig fat. (The *Shenghui Fang* states: Examine the gum roots for two yellow veins, cut them with a reed knife, and applying pig milk is excellent. If the infant's mouth is hard to open, first apply pig milk.) There are tendons connecting the upper and lower lips to the gums. If the tendon on the upper lip is tight, "Shang Lian" (Upper Lian) arises; if the tendon on the lower lip is tight, "Xia Lian" (Lower Lian) arises.
Shang Lian manifests as sores all over the head, or lesions resembling tinea on the eyebrows, with incessant itching and flowing yellow exudate, causing sores wherever it spreads. Xia Lian begins on the waist and back, gradually spreading to the four limbs, with symptoms similar to Shang Lian. If the disease is severe and untreated, or if the head and face become connected, persisting for years without improvement, it may lead to premature death or serious illness. This is precisely why wiping the mouth every morning is crucial [for prevention].
