茅先生∶小儿生下犯人噤候，面青黑，合两眼闭，吐逆不下乳，此候因生下来
不免外人看问，或有腋气，或因妇人月假不净，或外人带邪神触着，生下来夹故乳
哺，使触异气之物，气血未就，又被风邪击致此。所治者先用朱砂膏（方见惊积门中）乳上
吮下，后用镇心丸（惊）夹腥脾散（不乳食）与服即愈。如见不下乳，眼视、肚硬，死
候。大凡初生下儿子，家中人不见，不可便与外人入房看问，人家各有神只，又恐
妇人腋气及月假不净触着，恐中客忤，此即是养儿之法。

《简要济众》治小儿中马毒客忤，取马尾于儿面前烧，令儿咽烟气，日烧之，瘥为度。
又方 取马口角沫，涂儿口中，效。
茅先生说：小儿出生后患上客忤证，面色青黑，双眼紧闭，呕吐不能进食乳汁。这种病症是因为出生后难免有外人探视，或者有人身上有狐臭，或者因妇女月经未净，又或者外人带着邪神之气触碰了婴儿，导致在哺乳时触碰到带有异气之物。由于小儿气血尚未稳固，又被风邪侵袭而引发此病。治疗时，先用朱砂膏（方剂见惊积门中）涂在乳头让婴儿吮吸，然后再服用镇心丸（用于惊悸）或夹腥脾散（用于不乳食）即可痊愈。如果见到婴儿不吃奶、眼睛凝视、腹部坚硬，则是死证。大凡刚出生的婴儿，家中人不要立即让外人进房探视，因为各家都有神灵，又担心妇女的腋气及月经污秽触犯婴儿，恐怕导致客忤，这就是养育婴儿的方法。
《千金方》记载：剪取驴前腿肩胛处旋转生长的毛发，大小如弹子，用乳汁煎煮，使毛发溶解，药成后，涂在乳头上让婴儿饮用，药入喉即愈。另外，烧母亲衣带三寸连同头发，混合乳汁服用。另外，取牛鼻分泌的津液给婴儿服用。另外，取牛口沫敷在乳头上让婴儿饮用。

使用以前从人头囟门上取下的十根头发，加上少许断开的婴儿脐带，一起烧成灰，研成细末，与乳汁调和喂给婴儿，即可痊愈。
《千金方》论述说：凡是骑马出行的人，沾染了马汗的臭气，没有盥洗更换衣物，就靠近婴儿，会导致婴儿患马客忤。婴儿突然见到马匹，以及听到马鸣受惊，或者接触马上衣物上的马气，都会导致小儿患马客忤。需谨慎防护，特别是一岁以内的婴儿。其症状表现为腹痛，吐出青、黄、白色的液体，水谷分离，严重的会导致夭折。
《千金方》治疗小儿患马客忤的方法。（治疗客忤中人同样适用。）
用米粉制成丸子，像豆豉那么大，按摩婴儿的手足心、胸口、肚脐上下，来回摩擦。念咒语说：“摩家公，摩家母，摩家子儿苦于客忤，从我开始，扁鹊虽然良善，不如善于吐唾良效。”咒语念完后，将丸子丢弃在路上。
另一种方法：
取一把刀，横放在灶上，解开婴儿的衣服，露出心腹部（《翼》注：发作拨），拿起刀对着婴儿，念咒语：“唾辄以刀拟向心腹，啡啡（音非，吐唾的样子），煌煌，日出东方，背阴向阳，葛公葛公不知何公（《冀》注云：葛公葛母不知何公），子来不视去罔顾，过与生人忤，梁上尘是天之神，户下土是鬼所经，大刀环犀对灶君二七唾，客愈儿惊唾啡啡。”每吐一次唾沫就用刀对着比划，咒语念三遍才结束，用豆豉丸也按照上述方法做五六遍结束后，取这个丸子掰开看里面是否有毛，将丸子丢弃在路上，人客忤和马客忤就都痊愈了。
《简要济众方》治疗小儿患马毒客忤，取马尾在婴儿面前烧，让婴儿吸入烟气，每天烧，直到病愈为止。
另一个方子：取马口角的唾液，涂抹在婴儿口中，有效。
Mao Xiansheng stated: When an infant develops Ke Wu (Guest Worry, a condition caused by external spiritual or environmental factors) after birth, the complexion appears cyanotic and dark, the eyes are tightly closed, vomiting occurs preventing milk intake. This condition arises because after birth, it is inevitable for outsiders to visit; there may be individuals with body odor, or those affected by a woman's unclean menstruation, or outsiders carrying evil spirits who touch the newborn. Consequently, during breastfeeding, the infant is exposed to objects with abnormal qi. Since the infant's qi and blood are not yet established, they are struck by wind-pathogens, leading to this disease. Treatment should first apply Zhusha Gao (Cinnabar Paste, see the Jing Ji section for the formula) to the nipple for the infant to suckle, followed by administering Zhenxin Wan (Heart-Calming Pill, for palpitations) or Jiaxing Pi San (Clam Spleen Powder, for anorexia), which will result in recovery. If the infant refuses milk, stares fixedly, and has a hard abdomen, it indicates a fatal prognosis. Generally, for a newborn, family members should not immediately allow outsiders to enter the room for inspection, as each household has its own deities, and one must fear that a woman's axillary odor or menstrual impurity might offend the infant, causing Ke Wu. This is the method of nurturing infants.
The *Qianjin Fang* records: Cut hair from the rotating fur on the donkey's front shoulder blade, sized like a bean, decoct it in cow's milk until the hair dissolves. Once the medicine is prepared, apply it to the nipple for the infant to drink; upon entering the throat, the condition is cured. Alternatively, burn three cun of the mother's girdle along with hair, mix with cow's milk, and administer. Another method is to take the nasal mucus of a cow and administer it. Yet another method is to apply the saliva from a cow's mouth to the nipple for the infant to drink.
To treat infants who feel distressed when seeing people and have sounds in their abdomen, use the Sanwu Shaofen San (Three-Item Calcined Powder) formula.
Take ten strands of hair previously removed from the fontanelle of a person, add a small amount of the severed umbilical cord of the infant, calcine them together into ash, grind into fine powder, mix with milk, and feed to the infant, resulting in immediate cure.
The *Qianjin Fang* discusses: Whenever individuals travel on horseback, they absorb the foul smell of horse sweat. If they do not wash and change clothes before approaching the infant, it causes the infant to suffer from Ma Ke Wu (Horse Guest Worry). The infant suddenly seeing a horse, hearing a horse neigh and becoming frightened, or coming into contact with horse odor on clothing from the horse, all cause the infant to suffer from Ma Ke Wu. Careful protection is essential, especially for infants under one year old. The symptoms include abdominal pain, vomiting of green, yellow, or white fluids, separation of water and grain in the stool, and severe cases may lead to premature death.
The *Qianjin Fang* method for treating infants suffering from Ma Ke Wu (applicable also to human Ke Wu):
Make pills from rice flour, sized like soybeans. Rub them on the infant's palms, soles, chest center, and above and below the umbilicus, moving in circular motions. Chant the spell: "Mo Jiagong, Mo Jiamu, Mo Jizi'er ku Yu Ketou, cong wo shi, Bianque sui liang buru shan tuo liang." (Rubbing Master Father, Rubbing Mother, Rubbing Child suffers from Guest Worry, starting from me, although Bian Que is good, skilled spitting is better.) After chanting, discard the pill on the road.
Another method:
Place a knife horizontally on the stove, undress the infant to expose the heart and abdomen (*Yi* commentary notes: expose the area), hold the knife towards the infant, and chant: "Tuo zhe yi dao ni xiang xin fu feifei huanghuang, ri chu dongfang beiyin xiangyang, Ge Gong Ge Gong buzhi he gong (Ji commentary says: Ge Gong Ge Mu buzhi he gong), zi lai bu shi qu wanggu, guo yu shengren tou, liangshang chen tian zhi shen, huxia tu gui suo jing, da dao huan xi dui zao jun erqi tuo, ke yu er jing tuo feifei." (Spit towards the heart and abdomen with the knife, feifei [sound of spitting], brilliant, sun rises in the east, turning back from shade to face the sun, Mr. Ge Mr. Ge, unknown whose master, you come without looking, leave without caring, offending living people, dust on the beam is the god of heaven, soil under the door is where ghosts pass, great knife ring rhino facing the stove lord, spit twice seven times, guest leaves child startled spit feifei]. Spit each time while pointing the knife at the infant. Repeat the chant three times to finish. Use the soybean pill similarly for five or six repetitions. Then break the pill to check if there is hair inside, and discard it on the road. Both human and horse Ke Wu will be cured.
The *Jianyao Jizhong Fang* treats infants suffering from Ma Du Ke Wu (Horse Poison Guest Worry) by burning horse tail hair in front of the infant, allowing the infant to inhale the smoke. Burn daily until recovered.
Another prescription: Take the saliva from the corner of the horse's mouth, apply it to the infant's mouth, which is effective.
