巢氏云∶小儿中客忤者，是小儿神气软弱，忽有非常之物，或未经识见之人触
之，与儿神气相忤而发病，谓之客忤也，亦名中客，又名中人。其状吐下青黄白色，
水谷解离，腹痛反倒天矫，面变易五色，其状似痫，但眼不上插耳，其脉弦急数者
是也。若失时不治，久则难治，若乳母饮酒过度醉，及房劳喘后乳者最剧，能杀儿
也。（其脉急数者，宜与龙胆汤下之，加人参、当归、各如龙胆秤分等多少也。）
《千金》论少小所以有客忤病者，是外人来，气息忤之，一名中人，是为客忤也，
虽是家人，或别房异户，虽是乳母及父母，或从外还，衣服经履鬼神粗恶暴气，或
牛马之气，皆为忤也，执作喘息，乳气未定者，皆为客忤。凡小儿衣布帛绵中，
不得有头发，履中亦尔。白衣青带，青衣白带，皆令中忤。凡非常人及诸物从外
来，亦惊小儿致病，欲防之法，诸有从外来人及异物入户，当将儿避之，勿令见，
若不避者，烧牛屎令常有烟气，置户前则善。小儿中客为病者，无时不有此病也，
而秋初一切儿皆病者，岂一切儿悉中客邪，幼儿所以春冬少病，秋夏多病者，
秋夏小儿阳气在外，血脉嫩弱，秋初夏末晨夕时有暴冷，小儿嫩弱其外，则易伤暴
冷折其阳，阳结则壮热，胃冷则下痢，故夏末秋初，小儿多壮热而下痢，未必悉是
中客及 也。若治少小法，夏末秋初，宜候天气温凉，有暴寒卒冷者，其少小则多
患壮热而下痢也，慎不可先下之，皆先杀毒，后下之耳。小儿中客，急视其口中
悬痈左右，当有青黑肿脉核如麻豆大，或赤或白或青，如此，便宜用针速剌，溃去
之，亦可爪摘决之，并以绵缠钗头拭去血也。少小中客之病，吐下青黄赤白汁，腹
中痛，及反倒偃侧，喘似痫状，但目不上插少睡耳，面变五色，其脉弦急，若失时
不治，小久则难治矣。欲疗之方，用豉数合，水拌令湿，捣熟，丸如鸡子大，以摩
儿囟上、足心各五六遍毕，以丸摩儿心及脐上下行转摩之，食顷，破视其中，当有
细毛，即掷丸道中，痛即止。

巢元方说：小儿患客忤病，是因为小儿神气虚弱，忽然遇到不寻常的事物，或者从未见过的人接触他，这些外来的因素与小儿的神气相冲撞而引发疾病，这叫做客忤，也叫做中客，还叫中人。其症状表现为呕吐和腹泻青色、黄色或白色的物质，食物与水谷分离，腹痛且身体向后反折扭曲，面色变幻不定呈现五色，症状类似癫痫，但眼睛不上翻，脉象弦急而数，这就是客忤病的表现。如果错过时机不治疗，时间久了就难以治愈。如果是乳母饮酒过量醉酒后，或者房事劳累喘息未定时哺乳，病情最为严重，甚至能导致婴儿死亡。（如果脉象急数，适宜用龙胆汤攻下，加入人参、当归，用量与龙胆草的剂量相等。）
《千金方》论述小儿之所以会有客忤病，是因为外人到来，气息冲撞了小儿，一名中人，这就是客忤。即使是家人，或者住在别的房间不同的门户，即使是乳母及父母，如果从外面回来，衣服经过沾染了鬼神粗恶暴戾之气，或者牛马的气味，都算作冲撞。正在劳作喘息、乳气未定的时候哺乳，都算作客忤。凡是小儿的衣服布料绵絮中，不能有头发，鞋子里也不能有头发。白衣配青带，青衣配白带，都会导致中忤。凡是不寻常的人和各种物体从外来，也会惊吓小儿致病。预防的方法是，凡是有从外来的人和异物进入屋内，应当让小儿避开，不要让他看见。如果不避开，烧牛粪使其常有烟气，放在门口就好。小儿患客忤病，任何时候都可能发生，但为什么初秋时节所有小儿都生病呢？难道所有小儿都中了客忤吗？幼儿所以在春冬季节少病，秋夏季节多病，是因为秋夏季节小儿阳气在外，血脉嫩弱，初夏末和秋初早晚时有突然的寒冷，小儿体表嫩弱，容易受到暴冷伤害而损伤阳气，阳气郁结则壮热，胃寒则下痢，所以夏末秋初，小儿多出现壮热和下痢，未必都是中客忤病。如果治疗小儿的方法，在夏末秋初，应当观察天气是否温凉，如果有突然的寒冷，小儿就容易患壮热而下痢的病，千万不要先用攻下法，都应该先杀毒，然后再攻下。小儿患客忤病，急忙查看其口中悬雍垂左右，应该有青黑色的肿胀脉络结节如麻豆大小，颜色或赤或白或青，如此情况，便应该立即用针快速刺破，溃破排出脓血，也可以用指甲掐破挤出，并用棉絮缠绕钗头擦拭干净血液。小儿患客忤病，呕吐和腹泻青黄赤白的汁液，腹中疼痛，以及身体反折侧卧，喘息类似癫痫状，但眼睛不上翻，睡眠较少，面色变幻五色，脉象弦急，如果错过时机不治疗，稍久就难治了。治疗此病的方子，用豆豉几合，用水拌湿，捣熟，做成如鸡蛋大的丸药，用来摩擦小儿囟门、足心各五六遍，然后用丸药摩擦小儿心窝及脐部上下转动摩擦，过一会儿，剖开看其中，应该有细毛，就将丸药扔在路上，疼痛就会停止。
真珠散：治疗客忤、惊风、鬼疰，惊邪痰热，心神不安，精神不定，心中常怔忡，睡中惊跳，有时咬牙，五心烦热，有汗兼气喘，面赤舌白，呵欠烦渴，小便赤涩，或呕吐腹泻黄沫，常服可辟邪安神。

Chao Yuanfang stated: When a child suffers from *Ke Wu* (Guest Invasion), it is because the child's Shen Qi (Spiritual Energy) is weak. Suddenly, encountering extraordinary objects or people they have never seen can touch them. These external factors clash with the child's Shen Qi, causing illness, which is called *Ke Wu*, also known as *Zhong Ke* (Middle Guest) or *Zhong Ren* (Hitting Person). The symptoms include vomiting and diarrhea of green, yellow, or white substances, separation of food and fluids, abdominal pain with the body arching backward and twisting, facial color changing unpredictably through five hues, and symptoms resembling epilepsy but without upward deviation of the eyes. The pulse is wiry, rapid, and hurried; this is *Ke Wu*. If treatment is delayed, it becomes difficult to cure later. If the wet nurse has drunk excessively to intoxication, or nurses the child after sexual exertion while panting, the condition is most severe and can kill the infant. (If the pulse is urgent and rapid, it is appropriate to administer Long Dan Tang [Gentian Decoction] to purge, adding Ginseng Radix et Rhizoma and Angelicae Sinensis Radix in amounts equal to that of Gentiana Scabra Root.)
The *Qian Jin Fang* discusses why infants suffer from *Ke Wu*: it is caused by outsiders arriving whose breath clashes with the child, hence named *Zhong Ren*, which is *Ke Wu*. Even family members, or those in other rooms or households, including wet nurses and parents, if returning from outside where their clothes have been exposed to coarse, evil, violent qi of ghosts and spirits, or the odor of cattle and horses, all constitute a clash. Nursing while panting from labor or when breast milk qi is unsettled all count as *Ke Wu*. In children's clothing made of silk, cotton, or wadding, there must be no human hair, nor in shoes. White clothes with green belts, or blue clothes with white belts, all cause *Zhong Wu*. Any unusual person or object coming from outside can also frighten the child and cause disease. To prevent this, when strangers or strange objects enter the house, the child should be kept away and not allowed to see them. If not avoided, burning cow dung to create smoke and placing it at the door is beneficial. Children can suffer from *Ke Wu* at any time, but why do all children fall ill in early autumn? Do all children suffer *Ke Wu*? Infants get less sick in spring and winter but more in autumn and summer because in these seasons, the child's Yang Qi is on the exterior, and blood vessels are tender and weak. In late spring/early summer and early autumn, sudden cold occurs in the morning and evening. The child's tender exterior easily suffers from sudden cold, damaging Yang Qi. Constricted Yang leads to high fever; cold stomach leads to dysentery. Thus, in late summer and early autumn, children often have high fever and dysentery, which may not all be due to *Ke Wu*. Regarding pediatric treatment, in late summer and early autumn, one should observe if the weather is cool or if there is sudden cold. Children are prone to high fever and dysentery under such conditions. One must not use purgatives first; instead, one should first detoxify, then purge. For children suffering from *Ke Wu*, urgently examine the area around the uvula in the mouth. There should be swollen, wiry nodules, green-black in color, size of hemp seeds or beans, appearing red, white, or green. In such cases, quickly puncture with a needle to drain, or break with fingernails and wipe away blood with cotton-wrapped hairpins. Symptoms of *Ke Wu* in infants include vomiting and diarrhea of green, yellow, red, or white juices, abdominal pain, body arching and lying on side, panting resembling epilepsy, but eyes do not deviate upward, sleep is scant, face changes colors, and pulse is wiry and urgent. If untreated for too long, it becomes hard to cure. A prescription for this uses several heaping measures of Fermented Soybean (*Douchi*), moistened with water, pounded until ripe, formed into pills the size of chicken eggs. Rub these pills on the fontanelle and soles of feet 5-6 times each, then rub the heart area and above/below the navel in circles. After a short while, break open the pill; fine hairs should be found inside. Throw the pill into the road, and the pain will stop.
Zhenzhu San (Pearl Powder): Treats *Ke Wu*, wind-stroke from fright, ghostly affections, pathogenic heat from phlegm due to fright, restless mind, unstable spirit, constant palpitations, startle during sleep, teeth grinding, heat in palms/soles/chest, sweating with panting, red face with white tongue, yawning with irritability and thirst, dark/scanty urination, or vomiting/diarrhea of yellow froth. Regular use expels evil and calms the spirit.
Ingredients: Pearl (*Zhenzhu*), Cuttlefish Bone (*Haipiaoxiao*), Talcum (*Huashi*) (each 1 qian); Poria (*Baifuling*), Ginseng (*Renshen*), Aconite Root Prepared (*Baifuzi*), Licorice Root Honey-fried (*Gancao*), Scorpion (*Quanxie*), Musk (*Shexiang*), Borneol (*Naozi*) (separately ground, each 5 qian); Raw Pearl (*Shengzhu*) (separately ground, 1 qian); Gold Leaf (*Jinbo*) (30 pieces); Silver Leaf (*Yinbo*) (20 pieces).
Preparation: Grind all ingredients into fine powder and mix evenly. Take 0.5 qian, decoct Juncus Effusus Caulis (*Dengxincao*) and Ophiopogon Japonicus Radix (*Maidong*), add a little honey, and take orally. Dose once at noon and once before bed.
Tan Shi Shu Sheng treats *Ke Wu*:
Suddenly crying continuously without rest, whole body high fever, pulse like a hook, startled crying blaming gods and ghosts, *Ke Wu* hurts the heart, unable to control oneself. Rhinoceros Horn (*Xijiao*) and Realgar (*Xionghuang*) pounded together, Peach Talisman (*Taofu*) decocted in water to check consistency, Ginseng (*Renshen*), Poria (*Fuling*), Plantago Seed (*Cheqianzi*). Pill form, take three doses, do not worry.
Anshen Wan (Calming Spirit Pill):
Raw Rhinoceros Horn Powder (*Shengxi Mo*) (0.5 qian), Realgar (*Xionghuang*) (ground), Ginseng (*Renshen*), Poria (*Fuling*), Plantago Seed (*Cheqianzi*) (each 1 fen).
Preparation: Grind into powder. Take 1 liang of Peach Bark Inner Layer (*Tao Baipi*) and 1 liang of Peach Talisman (*Taofu*). Decoct these two in 3 sheng of water until reduced to 1 sheng. Strain, then boil down to a paste. Mix with the previous powders to form pills the size of sesame seeds. Take 3 pills per dose, washed down with Peony Decoction (*Shaoyao Tang*).
Another Prescription: Child choking qi beating heart continuously, panting with much sorrow and gastric saliva, only this disease should be treated early, because *Ke Wu* qi causes frying/torment. Looking at the symptoms, medical effect is hard to achieve. Quickly take Zhenzhu San 0.5 qian, Borneol (*Longnao*), Raw Rhinoceros Horn (*Shengxi*), Cyperus Rhizome (*Xiangfuzi*). After the child eats, body will be safe.
Zhenzhu San: Pearl Powder (*Zhenzhu Mo*) (4 qian), Raw Rhinoceros Horn Powder (*Shengxi Mo*) (2 qian), Cyperus Rhizome Powder (*Xiangfuzi Mo*) (1 qian), Borneol (*Longnao*) (half zi).
Preparation: Grind together. Take 1 zi per dose, mixed with Peach Kernel Decoction (*Taoren Tang*). Wet nurse should avoid raw/cold, greasy foods, and all toxic substances for half a month.
[Zhang Huan] Pixie Gao (Evil-Expelling Ointment): Infants' blood and qi are not yet solid, all have weak Shen Qi. Except for routine care by parents and wet nurses, do not let children see strangers, or carry them to other rooms/households, nor see cattle, horses, or beasts. Parents or family members returning from outside, even late at night, should not be seen by the child, lest they bring coarse, evil, violent qi from ghosts/spirits. If attacked by this qi, the child vomits and diarrhes green, yellow, red, white, separating food and fluids, resembling epilepsy but eyes do not deviate upward, pulse not wiry/urgent, named *Ke Wu*. (Weaned children who suddenly suffer from evil attacks should also take this medicine, waking up immediately.)
Ingredients: Liquidambar Fructus (*Jiangxiang*) (chopped), Commiphora Myrrha Resin (*Baijiaoxiang*), Aquilaria Wood (*Chenxiang*), Tiger Skull (*Hutougu*) (lightly fried), Podophyllum Rhizome (*Guijiu*) (de-haired), Gentiana Scabra Root (*Caolongdan*), Ginseng (*Renshen*), Poria (*Baifuling*).
Preparation: Each ingredient 0.5 liang, pound and sieve into fine powder. Add 0.5 liang Realgar (*Xionghuang*) ground with water, finely研 (pulverized via levigation). Then grind 1 qian Musk (*Shexiang*). Mix all uniformly, blend with refined honey to form pills the size of a chicken head. Take 1 pill per dose, dissolve in Frankincense Decoction (*Ruxiang Tang*). Additionally, make pills the size of marbles, store in green silk bags, attach to child's clothes, and frequently burn Shenmiao incense in the sleeping area.
[Tian] Treatment for *Ke Wu* leading to fright-clash: Use 2 liang of loess from the hearth (*Zaohuangtu*), one egg white (shell removed). Mix both with a little water. First bathe the child in Peach and Willow Branch Decoction (*Taoliuzhi Tang*), then apply this medicine to the five centers (palms, soles, chest) and top of the head. (Chen Wuyue's method uses equal parts loess and earthworm feces, applied similarly.)
Treatment for sudden *Ke Wu* with locked jaw inability to speak: Equal parts Asarum (*Xixin*) and Cinnamon Twig (*Guixin*), place in mouth, effective.
He Yuan Ji Yong Jing treats pediatric *Ke Wu*: Pound Calamus Rhizome (*Changpu*) juice and place in mouth. Or use fresh Mugwort Juice (*Aiye*) placed in mouth. Or use 3-4 drops of whetstone water, excellent. Or use good ink, pound and sieve, mix with water, warm dose of half a qian-bi.
