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。
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.
