婴儿在母胎中，口中含有热性物质，这就是所谓的“胎毒”。婴儿出生后、啼哭声尚未发出时，应立即用棉布包裹手指，将口中的胎毒取出，并用棉布擦拭干净口腔。关键在于动作迅速，若迟缓则胎毒会被咽下。
《产家要诀》记载：婴儿产出后，应先清洗身体再断脐带，这样就不会因受水湿侵袭而生病。断脐时必须将脐带内的血液挤尽，否则寒湿之气会侵入腹部，可能引发“脐风”（新生儿破伤风）。另外，需在距离脐部四、五寸处用线扎紧，用棉布包裹，然后用口咬断脐带。因为扎紧后胎儿的血液不会流入胎盘（胞衣），胎盘自然会萎缩且不胀大，容易排出。即使延缓几天处理，也没有大害。用口咬断可以避免刀剪带来的寒气侵入体内，从而免除腹部疼痛的担忧。如果天气寒冷，分娩艰难，导致母子元气受损，应先扎紧脐带，用浸油的纸捻点燃火烧断脐带，让暖气进入婴儿腹中，这又是起死回生的妙法。近来有用蕲艾（Qichai Mugwort）灸治脐部的，这种方法也很奇妙。留下的脐带不可太长，太长则难以干燥且易损伤肌肤，还恐怕引动外风导致脐风；也不可太短，太短则会逼迫内部并损伤脏腑，可能导致腹痛和夜间啼哭。适宜以婴儿脚掌的长度为标准，这是折中的方法。《千金论》说：应以到达婴儿足背为度。《造道集》说：婴儿刚出生宜先洗净，使燥血不留在脐带折断处之间，可使皮肤光泽，然后剪断脐带。脐带是初生时的蒂柄，剪断时应留长一尺二寸，用粗线缚紧。剪得不长多生脐风，缚得不紧会导致阴部虚肿。
《千金论》说：包裹脐部需用白色熟绢柔软者，宽四寸，新棉花厚度半寸，与帛相当，合起来松紧适度，过紧会让婴儿呕吐。不可轻易解开，解开时要关闭门窗放下帐子，冬季用火使帐内温暖，仍用温粉敷贴。如果脐部不干，可用烧成灰的红帛敷贴。
又一方：枯矾五钱、龙骨一钱、黄丹一钱、麝香少许，共研成粉末敷贴。
另外，头发烧成灰敷贴也可以。有人说：用黄柏末敷贴也很好。
While in the womb, the infant possesses a hot substance in the mouth, which is termed "fetal toxin" (Tai Du). Before the infant's cry is emitted after birth, one should immediately wrap a finger with cotton, remove the fetal toxin from the mouth, and wipe the oral cavity clean with cotton. Speed is crucial; delay may result in the swallowing of the toxin.
The *Chan Jia Yao Jue* states: After the child is born, washing the body before cutting the umbilical cord prevents illness caused by water-dampness. When cutting the cord, all blood must be drained; otherwise, cold-dampness may enter the abdomen, potentially causing "umbilical wind" (Qi Feng, neonatal tetanus). Furthermore, tie the cord tightly four or five cun away from the navel, wrap it with cotton, and bite it off with the teeth. Tying it tightly prevents fetal blood from flowing into the placenta, allowing the placenta to naturally shrink without swelling and facilitating its expulsion. Even if delayed for a few days, there is no major harm. Biting the cord avoids the introduction of cold qi via knives or scissors, thereby preventing abdominal pain. If the weather is cold, delivery is difficult, and the mother and child have depleted their vital energy, tie the cord tightly first, then use an oil-soaked paper twist ignited by fire to burn through the cord, allowing warm qi to enter the infant's abdomen. This is another miraculous method for reviving the dying. Recently, moxibustion on the navel using Qichai Mugwort has been used, which is also effective. The remaining umbilical cord should not be too long; if too long, it will be difficult to dry and prone to damaging the skin, and may attract external wind leading to umbilical wind. It should not be too short either; if too short, it may press inward and damage the zang-organs, potentially causing abdominal pain and night crying. The appropriate length should be measured by the infant's sole, which is a balanced approach. The *Qian Jin Lun* states: the length should reach the dorsum of the infant's foot. The *Zao Dao Ji* states: upon birth, the infant should be washed cleanly so that dried blood does not remain between the severed parts, allowing the skin to become lustrous before cutting the cord. The umbilical cord is the stalk of new life; when cutting, leave one chi two cun, and bind it tightly with thick thread. If cut too short, umbilical wind often arises; if bound too loosely, swelling of the yin region occurs.
The *Qian Jin Lun* states: To wrap the navel, use soft white silk, four cun wide, and new cotton half an cun thick, matching the thickness of the silk. Together, they should fit snugly but not too tight, as excessive tightness may cause the infant to vomit. Do not untie it lightly. When untying, close doors and windows and lower the curtains. In winter, use fire to keep the interior of the curtain warm, and apply warm powder. If the navel does not dry, apply ash made from burning red silk.
Another prescription: Calcined Alum (Ku Fan) 5 qian, Dragon Bone (Long Gu) 1 qian, Lead Oxide (Huang Dan) 1 qian, and a small amount of Moschus (Shexiang), ground together into powder for application.
Alternatively, ash from burnt hair can be applied. Some say applying Powder of Phellodendri Cortex (Huang Bai Mo) is also excellent.
