婴儿出胎，口有恶物，即胎毒也。须于啼声未出之前，急用软帛或用丝绵裹手指，蘸甘草汤（甘草少许，用
沸汤泡汁，以淡为妙，不宜太甜），遍拭口中。去其秽浊贵在神速，迟则咽下，致生诸病。若母气素寒，小儿
清弱及产时收生迟慢，致受风寒者，宜以淡姜煎汤拭口，最能去胃寒，通神明，并可免吐泻之患，此法最妙。
世俗不察，而以为婴儿体热，宜遵古法用甘草、黄连浓煎汁拭口者，不知黄连大苦大寒，而小儿以胃气为主，
若初生与以大寒致损胃气，则他日作泻、作呕由此起矣。但淡姜汤惟不宜于夏月耳。
婴儿初生，即拭去口中恶物，随用胡桃二枚（油者勿用，去壳及皮取肉），嚼极细烂，用稀绢或薄纱包如枣
核大，安儿口中，使吮其汁，非独和中，且能养脏，最佳法也。若母气多热小儿肥盛者，宜用牛黄（五厘）
朱砂（五分，水飞） 研极细末，热蜜调匀，薄绢包如枣核大，与吮为佳，极能辟痰邪、去秽恶，除热安神，庶
免惊痫之患。若婴儿清弱者用。又经验方中用橄榄核一枚（烧灰存性，研极细末），朱砂（五分，水飞），和匀，
外用生芝麻一撮，口嚼细津吐和药绢包如枣核大，与之吮，取下肠胃秽毒，令儿少痰及麻痘亦稀少也。此惟母
体素强，婴儿体实者宜之。
子在腹中胞胎十月止，于脐中与母通气。虽出胞胎，其脐中所通之气犹未尽绝，断脐之后招风致病者有之，
其法必须先用熟汤浴过，不使水气入内，然后方断脐带，则不伤水生病。断脐须将汁令尽，否则寒湿入腹，或作
脐风，又须于近脐四、五寸处，以绵扎紧，以帛包裹，以口咬断，令暖气入儿腹中，此又为起死回生之妙法。
近用艾叶灸脐亦妙。所留脐带不可太长，太长则难干而伤肌，且恐引外风入腹变为脐风。亦不可太短，太短则
逼内而伤脏，或致成腹痛而夜啼。只以儿之足掌为度。
婴儿出生时，口中若有污秽之物，这就是胎毒。必须在婴儿啼哭之前，迅速用柔软的丝织品或丝绵包裹手指，蘸取甘草汤（取少量甘草，用沸水冲泡出汁，以味道清淡为宜，不宜过甜），彻底擦拭口腔。去除污浊的关键在于动作神速，如果迟缓，污物被咽下，就会导致各种疾病。如果母亲体质素来虚寒，小儿先天清弱，以及分娩时接生迟缓，导致受风寒侵袭的，宜用淡姜汤擦拭口腔，这最能祛除胃中寒气，通利神明，并且可以避免呕吐腹泻的祸患，这种方法非常巧妙。世俗之人不加考察，认为婴儿体内有热，应当遵循古法用甘草、黄连浓煎汁液擦拭口腔，却不知道黄连大苦大寒，而小儿以胃气为本，如果在初生时就给予大寒之药损伤胃气，那么日后发生腹泻、呕吐便由此而起。只是淡姜汤在夏季不宜使用罢了。
婴儿刚出生，立即拭去口中的污秽之物，随即取胡桃两枚（含油量高的不要用，去掉外壳及内皮取果肉），嚼得极细烂，用稀绢或薄纱包裹如枣核大小，放入婴儿口中，让婴儿吮吸其汁液，这不仅能够调和脾胃，而且能滋养脏腑，是最好的方法。如果母亲体质多热，小儿体格肥盛的，宜用牛黄（五厘）朱砂（五分，用水飞法研磨），研成极细粉末，用热蜂蜜调匀，用薄绢包裹如枣核大小，让婴儿吮吸为佳，极能辟除痰邪、去除秽恶，清热安神，从而避免惊风癫痫的祸患。如果是先天清弱的婴儿则不适用此法。另有经验方中使用橄榄核一枚（烧成灰但保留药性，研成极细粉末），朱砂（五分，用水飞法研磨），混合均匀，外用生芝麻一撮，在口中嚼碎吐出的津液与药物混合，用绢包裹如枣核大小，给婴儿吮吸，可以排出肠胃中的秽毒，使婴儿痰少，且麻疹痘疮也会稀少。这仅适用于母亲体质素强，婴儿体格健壮的。
胎儿在母腹中怀胎十月，通过脐带与母亲通气。虽然离开了胞胎，但脐中所通的之气尚未完全断绝。断脐之后因招致风邪而致病的案例是有的。处理方法是必须先用熟开水洗浴，不让生水之气入内，然后才断脐带，这样就不会因水湿致病。断脐时必须将脐带内的汁液挤尽，否则寒湿进入腹部，可能会引发脐风。还必须在距离脐部四、五寸处，用棉线扎紧，用布包裹，用口咬断脐带，让暖气进入婴儿腹中，这又是起死回生的妙法。近来有用艾叶灸脐的方法也很好。留下的脐带不可太长，太长则难以干燥而损伤肌肤，且恐怕引外风入腹变为脐风。也不可太短，太短则会逼迫内部而损伤脏腑，或者导致腹痛和夜间啼哭。只以婴儿足掌的长度为标准。
When the infant is born, if there are foul substances in the mouth, this is fetal toxin (Tai Du). Before the infant cries, one must urgently use soft silk or cotton-wrapped fingers dipped in Licorice Decoction (Gancao Tang: a small amount of Glycyrrhizae Radix et Rhizoma soaked in boiling water to extract the juice; it should be light in flavor, not too sweet) to thoroughly wipe the oral cavity. Removing the filth requires speed; if delayed, the filth will be swallowed and cause various diseases. If the mother's constitution has always been cold, the infant is congenitally weak, or delivery was slow leading to exposure to wind-cold, it is advisable to wipe the mouth with mild Ginger Decoction. This best dispels stomach cold, clears the mind and spirit, and prevents vomiting and diarrhea. This method is excellent. Laypeople, failing to observe correctly, believe infants have internal heat and should follow ancient methods using concentrated decoctions of Licorice and Coptis Rhizome (Huanglian) for wiping. They do not realize that Huanglian is extremely bitter and cold. Since infants rely on Stomach Qi, administering extreme cold substances at birth damages Stomach Qi, leading to future diarrhea and vomiting. However, mild Ginger Decoction is unsuitable in summer.
Immediately after birth, wipe away the foul substances from the infant's mouth. Then, take two walnuts (avoid oily ones), remove the shell and skin, and chew the flesh until very fine. Wrap it in thin silk or gauze to the size of a jujube pit, place it in the infant's mouth, and let the infant suck the juice. This not only harmonizes the middle jiao but also nourishes the zang organs, making it an optimal method. If the mother has excessive heat and the infant is robust, use Realgar (Shizhao, 5 li) and Cinnabar (Zhusha, 5 fen), ground into fine powder via water-floating method. Mix evenly with warm honey, wrap in thin silk like a jujube pit, and allow sucking. This effectively expels phlegm pathogens, removes filth, clears heat, calms the spirit, and prevents convulsions and epilepsy. It is not suitable for congenitally weak infants. Another empirical formula uses one olive pit (burned to ash but retaining its nature, ground fine), mixed with Cinnabar (5 fen, water-floating method). Add a pinch of raw sesame seeds, chew in the mouth, mix the saliva with the medicine, wrap in silk like a jujube pit, and give for sucking. This expels intestinal and gastric toxins, reduces phlegm, and minimizes measles and smallpox eruptions. This is suitable only when the mother is strong and the infant is robust.
The fetus remains in the womb for ten months, connecting with the mother via the umbilical cord for qi transmission. Even after leaving the womb, the qi connection through the umbilicus is not immediately severed. Infants may fall ill due to wind exposure after umbilical cord cutting. The proper method is to first bathe the infant with boiled water to prevent unboiled water qi from entering, then cut the umbilical cord to avoid illness caused by water dampness. When cutting, ensure all fluid in the cord is drained; otherwise, cold-dampness may enter the abdomen, potentially causing umbilical tetanus (Qi Feng). Tie the cord tightly with cotton four or five cun from the navel, wrap it with cloth, bite off the remaining part with your mouth, allowing warm qi to enter the infant's abdomen. This is a miraculous method for saving lives. Moxibustion on the umbilicus with Mugwort Leaf (Ai Ye) is also effective. The remaining umbilical cord should not be too long, as it may fail to dry, damage the skin, and invite external wind leading to umbilical tetanus. Nor should it be too short, as this may compress internal organs, causing abdominal pain and night crying. The length should be measured according to the sole of the infant's foot.
