儿生三日，以桑、槐、榆、桃、柳、各取嫩枝三寸长者，二三十节煎汤，看冷
热，入猪胆汁二三枚，浴之。浴汤用猪胆、益母草，不生疮疥。用金银、虎头骨、
麝、丹砂，辟恶气、客忤、惊痫。用桃、梅、李、楮根叶，解体热温壮之病，须浴
时煮。汤须不冷不热，于无风密室浴之，勿令久。浴讫，以粉摩之，或以光粉、
蚌粉，扑身辟邪，吉。《纪用经》浴法，寅、卯、酉日吉，壬午、丁未、癸巳
凶，不能上三日，勿犯下三日。（三日、五日、七日浴。）小儿洗浴，不可先断脐带，候洗了
方断，不致水湿伤脐，可免脐风、脐疮、等证，用清油调发灰敷脐。洗儿，不可用
水打湿脐带。
《千金》云∶脐不得以刀割，隔单衣咬断，以暖气呵七遍，即缠结，所留带致儿
足趺上断讫，连脐带中多有虫，急剔拨去，不尔，入脐成疾。脐当长六寸，长则伤
肌，短则伤脏，不以时断及 汁不尽，暖气渐微，即生寒令儿脐风。《宝鉴》论∶
断脐若用剪刀，先于怀中令暖。又，水入脐，多天钓，痛苦啼叫，面青黑。脐伤动，
令久不干。伤外风，即口噤不可救。
《圣惠》云∶儿生一宿，抱近明无风处，看脐上有赤脉直上者，即于脉尽头灸三
壮，赤散，无患矣。
《千金》论∶治白练令柔软，方四寸，新绵浓半寸，与帛等合之裹脐，调其缓急，
急则吐 ，二十日乃解，若十许日怒啼，必衣中有刺，或脐燥刺腹，当更裹脐，冬
时须闭户下帐，然火令温暖，换衣亦然，仍以温粉、粉之。
婴儿出生后第三天，取桑、槐、榆、桃、柳树的嫩枝，每样截取三寸长的段，共二三十节煎煮成汤。待水温适宜后，加入二三枚猪胆汁，给婴儿洗浴。此浴汤使用猪胆和益母草，可防止生疮疥。若加入金银、虎头骨、麝香、朱砂，可辟除恶气、客忤（外邪侵袭）、惊痫。若加入桃、梅、李、楮树的根叶，需在水中煮沸，以解除身体发热壮热之病。水温须不冷不热，在无风的密室中进行洗浴，时间不宜过长。洗浴完毕后，用爽身粉按摩身体，或使用光粉、蚌粉扑身以辟邪，为吉事。《纪用经》中的洗浴法认为，寅日、卯日、酉日吉祥，壬午日、丁未日、癸巳日凶险，不能在上三日洗浴，勿犯下三日。（指在婴儿出生后的第三日、第五日、第七日洗浴。）给小儿洗浴时，不可先剪断脐带，应等洗完后再剪断，这样可避免水湿损伤脐部，从而免除脐风、脐疮等证候。可用清油调和发灰敷于脐部。洗儿时，不可用水打湿脐带。
《千金方》说：脐带不得用刀切割，应隔着单衣咬断，并用暖气呵七遍，然后缠绕结扎。所留的脐带长度应使婴儿足背处断开。断口处及脐带中常多有虫，需急剔拨去除，否则虫入脐内会致病。脐带长度应当六寸，过长则伤肌肉，过短则伤内脏。若不按时断脐且汁液排不尽，暖气逐渐微弱，就会生寒导致婴儿患脐风。《宝鉴》论述：断脐若用剪刀，先在怀中令其温暖。另外，水进入脐部，多导致天钓（一种新生儿痉挛性疾病），痛苦啼叫，面色青黑。脐部受伤动扰，会导致久不干涸。若伤及外风，就会导致口噤（牙关紧闭）不可救治。
《圣惠方》说：婴儿出生一夜后，抱到明亮无风处，观察脐上有赤色脉络直上的，就在脉络尽头灸三壮，赤脉消散，便无祸患了。
《千金方》论述：治疗时用白练使其柔软，方形四寸，新绵厚半寸，与帛等同裹包裹脐部，调节松紧度。若太紧则导致呕吐，二十日后才解开；若十多日内愤怒啼哭，必定是衣服中有刺，或是脐部干燥刺激腹部，应当重新包裹脐部。冬季必须关闭门窗放下帐子，点燃火盆令室内温暖，换衣服时也如此，仍需用温粉涂抹。
On the third day after birth, take tender branches of mulberry, locust tree, elm, peach, and willow trees. Cut each to three cun in length, using twenty to thirty segments, and decoct them in water. Adjust the temperature to be suitable, add two or three pig gallbladders, and bathe the infant. Using pig gallbladder and Motherwort Herba (Yimucao) in the bathwater prevents sores and scabies. Adding gold, silver, tiger head bone, Moschus (Shexiang), and Cinnabar (Dansha) wards off evil qi, Ke Wu (external pathogenic invasion), and convulsions. Adding peach, plum, apricot, and paper mulberry root leaves, which must be boiled in the water, resolves febrile diseases with high fever. The water temperature should be neither cold nor hot; bathe in a windless, closed room, and do not prolong the time. After bathing, massage the body with powder, or use Guang Fen (refined talc) or Concha Tridacnae (Bangfen) to dust the body for warding off evil spirits, which is auspicious. According to *Ji Yong Jing*, the days of Yin, Mao, and You are auspicious, while Ren Wu, Ding Wei, and Gui Si are inauspicious; one should not bathe on the first three days nor violate the last three days. (Bathing is performed on the 3rd, 5th, and 7th days after birth.) When bathing infants, do not cut the umbilical cord first; wait until after washing to cut it, preventing water and dampness from injuring the navel, thereby avoiding conditions such as Umbilical Wind (Neonatal Tetanus) and Umbilical Sores. Apply hair ash mixed with clear oil to the navel. Do not wet the umbilical cord with water during bathing.
*Qianjin Fang* states: The umbilical cord must not be cut with a knife. It should be bitten through while separated by a single layer of clothing, then blown upon seven times with warm breath, and finally tied. The remaining cord should be severed at the level of the infant's instep. There are often worms in the severed end and within the cord; these must be promptly removed, otherwise they may enter the navel and cause disease. The umbilical cord should be six cun long; if too long, it injures the muscles; if too short, it injures the viscera. If not cut in time and the fluid is not completely drained, the warm breath gradually diminishes, leading to coldness and causing Umbilical Wind. *Bao Jian* discusses: If scissors are used to cut the cord, they should first be warmed in the chest. Furthermore, if water enters the navel, it often causes Tian Diao (a neonatal spasmodic disorder), resulting in painful crying and a cyanotic-black complexion. Injury to the navel causes it to remain moist for a long time. Exposure to external wind leads to trismus (lockjaw), which is incurable.
*Shenghui Fang* states: One night after birth, hold the infant near a bright, windless place. Observe if there are red vessels extending straight up from the navel. If so, moxaibustion should be applied three times (three moxa cones) at the end of the vessel. Once the redness dissipates, there will be no harm.
*Qianjin Fang* discusses: Treat by using white silk gauze made soft, four cun square, with half a cun thickness of new cotton wool, layered equally with the silk to wrap the navel. Adjust the tightness appropriately. If too tight, vomiting occurs, and it should be removed after twenty days. If the infant cries angrily for more than ten days, there may be a thorn in the clothing or dryness of the navel irritating the abdomen; in such cases, re-wrap the navel. In winter, doors and windows must be closed, curtains lowered, and a fire lit to keep the room warm; this applies similarly when changing clothes. Still, apply warm powder to the area.
