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，或者被未曾见过的人触碰，这些外来的因素与小儿的神气相互冲撞而发病，这就叫做客忤，也称之为中客，或者中人。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，腹部疼痛且身体反折扭曲，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。如果错过时机不及时治疗，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。（对于脉象急数的情况，适宜用龙胆汤攻下，并加入人参、当归，用量与龙胆草的剂量相等。）
《千金方》论述少小儿童之所以会有客忤病，是因为外人到来，其气息冲撞了小儿，一名叫中人，这就是客忤。即使是家人，或者是不同房间不同门户的亲属，即使是乳母及父母，如果从外面回来，衣服上沾染了经过鬼神居住处的粗恶暴戾之气，或者牛马的气味，都会造成冲撞。正在劳作后喘息未定就给婴儿哺乳，乳气未定，都属于客忤。凡是小儿的衣服布料棉絮中，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。凡是异常的人和各种物品从外来，也会惊吓小儿致病。想要预防的方法，凡是有从外面来的人和异物进入屋内，应当让小儿回避，不要让他看见。如果不回避，可以烧牛屎使常有烟气，放在门口就好。小儿患客忤病，任何时候都可能有此病，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，未必都是中客及（注：原文此处似有缺字，结合语境推测为某种邪气或病证）。如果治疗少小疾病的方法，在夏末秋初，应当观察天气是否温凉，如果有突然的寒冷，小儿就会多患壮热而下痢的病，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，大小如麻豆，颜色或红或白或青，如此时，应当立即用针快速刺破，溃破排出脓血，也可以用指甲掐破挤出，并用棉花缠绕钗头拭去血液。少小患客忤病，呕吐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，只是眼睛不上翻且睡眠较少，面色变幻五色，脉象弦急，如果错过时机不治疗，时间稍久就难治了。治疗此病的方子，用豆豉几合，用水拌湿，捣烂，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口及脐上下往返摩擦，过一顿饭的时间，剖开看其中，应该会有细毛，就将丸药扔在路上，疼痛就会停止。

Chao Yuanfang stated: When a child suffers from *Ke Wu* (Guest Intrusion), it is because the child's *Shen Qi* (Spiritual Energy) is weak. Suddenly encountering unusual objects or being touched by unfamiliar people causes these external factors to clash with the child's spiritual energy, leading to illness. This is called *Ke Wu*, also known as *Zhong Ke* (Struck by Guest) or *Zhong Ren* (Struck by Person). The symptoms include vomiting and diarrhea of green, yellow, or white substances, separation of food and fluids, abdominal pain with body twisting and arching, facial color changes presenting 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, become intoxicated, or breastfeeds immediately after sexual intercourse while panting, the condition is most severe and can be fatal to the infant. (For cases with a hurried and rapid pulse, it is appropriate to use *Long Dan Tang* (Gentian Decoction) to purge, adding *Renshen* (Ginseng) and *Danggui* (Angelica Sinensis), in amounts equal to that of *Long Dan Cao* (Gentian Root).)
The *Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold) discusses why infants suffer from *Ke Wu*: it occurs when outsiders arrive, and their breath clashes with the infant. It is also called *Zhong Ren*. Even family members, whether from different rooms or households, including wet nurses and parents, if they return from outside carrying coarse, violent, or evil qi from places visited by spirits/gods, or odors from cattle, horses, etc., can cause such clashes. Breastfeeding while still panting from labor, where the milk qi is unsettled, also constitutes *Ke Wu*. Children's clothing, cotton, and padding must not contain human hair, nor should shoes contain hair. White clothes with green belts, or blue clothes with white belts, can all induce *Ke Wu*. Any unusual persons or objects entering from outside can startle the child and cause disease. To prevent this, when strangers or strange items enter the house, the child should be kept away and not allowed to see them. If avoidance is not possible, burning cow dung to maintain smoke at the doorway is beneficial. *Ke Wu* can occur at any time, yet why do all children fall ill in early autumn? Does every child suffer from *Ke Wu*? Infants have fewer illnesses in spring and winter but more in autumn and summer because during 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 snaps occur at dawn and dusk. The child's tender exterior is easily injured by this sudden cold, damaging the *Yang Qi*. Constrained *Yang Qi* leads to high fever, while cold stomach leads to dysentery. Thus, in late summer and early autumn, infants often present with high fever and dysentery, which are not necessarily all due to *Ke Wu*. Regarding the treatment of infants, in late summer and early autumn, one should observe if the weather turns cool or experiences sudden cold. Infants will likely develop high fever and dysentery. One must not use purgatives first; instead, one should first eliminate toxins/poisons, and then purge. For infants suffering from *Ke Wu*, urgently examine the area around the uvula in the mouth. There should be swollen, dark blue-black nodules like hemp seeds, colored 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 around a hairpin. Infant *Ke Wu* presents with vomiting and diarrhea of green, yellow, red, or white juices, abdominal pain, body twisting and lying on sides, panting resembling epilepsy, but without upward eye deviation and with less sleep. Facial colors change, and the pulse is wiry and rapid. If untreated for too long, it becomes difficult to cure. A prescription for this uses several *Dou Chi* (Fermented Soybean Pills), moistened with water, pounded until soft, and formed into pills the size of a chicken egg. Rub these pills on the infant's fontanelle and soles of the feet five to six times each. Then rub the pill over the heart and above/below the navel in circular motions. After a meal interval, cut open the pill; fine hairs should be found inside. Throw the pill into the road, and the pain will cease.
*Zhen Zhu San* (Pearl Powder): Treats *Ke Wu*, *Jing Feng* (Wind of Shock), *Gui Zhu* (Ghost Tethering), pathogenic shock phlegm-heat, restless mind, unstable spirit, constant palpitations, night terrors, teeth grinding, heat in the five centers, sweating with panting, red face with white tongue, yawning with irritability and thirst, red scanty urine, or vomiting/diarrhea of yellow froth. Regular use expels evil and calms the spirit.
Ingredients: *Zhen Zhu* (Pearl), *Hai Piao Xiao* (Cuttlefish Bone), *Hua Shi* (Talcum), each 1 qian; *Bai Fu Ling* (Poria), *Renshen* (Ginseng), *Bai Fu Zi* (Aconitum Carlemanii Radix), *Gan Cao* (Licorice Root, honey-fried), *Quan Xie* (Scorpion), *She Xiang* (Musk), *Nao Zi* (Camphor, separately ground), each 5 qian; *Sheng Zhu* (Raw Pearl, separately ground), 1 qian; *Jin Bo* (Gold Leaf), 30 pieces; *Yin Bo* (Silver Leaf), 20 pieces.
Preparation: Grind all ingredients into fine powder and mix evenly. Take 0.5 qian, decoct *Deng Xin Cao* (Juncus Effusus) and *Mai Dong* (Ophiopogon Japonicus Rhizome), add a little honey, and take orally. Administer once at noon and once before bed.
*Tan Shi Shu Sheng* Prescription for *Ke Wu*:
Suddenly crying incessantly, whole body high fever, pulse like a hook, startled crying blaming spirits/gods, *Ke Wu* hurting the heart, unable to control oneself. Pound together *Xi Jiao* (Rhinoceros Horn) and *Xiong Huang* (Realgar). Decoct *Tao Fu* (Peach Wood Talisman) water to desired consistency. Add *Renshen* (Ginseng), *Fu Ling* (Poria), and *Che Qian Zi* (Plantago Seed). Form pills; taking three doses brings no worry.
*An Shen Wan* (Calming Spirit Pill):
*Sheng Xi* (Raw Rhinoceros Horn) powder, 0.5 qian; *Xiong Huang* (Realgar), ground; *Renshen* (Ginseng), *Fu Ling* (Poria), *Che Qian Zi* (Plantago Seed), each 1 fen.
Preparation: Grind into powder. Take 1 liang of *Tao Bai Pi* (Peach Bark) and 1 liang of *Tao Fu* (Peach Wood Talisman). Decoct in 3 sheng of water until 1 sheng remains. Strain, then reduce to a paste. Mix with the powder to form pills the size of sesame seeds. Take 3 pills per dose, washed down with *Shao Yao Tang* (Peony Decoction).
Another Formula:
Infant choking qi pounding the heart continuously, panting with much sorrow and gastric saliva, only this disease should be treated early, because *Ke Wu* qi is frying/consuming. Looking at the symptoms, medical efficacy is hard to achieve. Quickly take 0.5 qian of *Zhen Zhu San* (Pearl Powder), containing *Long Nao* (Borneol), *Sheng Xi* (Raw Rhinoceros Horn), and *Xiang Fu Zi* (Cyperus Rotundus). After the infant ingests it, safety is guaranteed.
*Zhen Zhu San* (Pearl Powder): *Zhen Zhu Mo* (Pearl Powder), 4 qian; *Sheng Xi Mo* (Raw Rhinoceros Horn Powder), 2 qian; *Xiang Fu Zi Mo* (Cyperus Rotundus Powder), 1 qian; *Long Nao* (Borneol), half zi.
Preparation: Grind together. Take one zi per dose, mixed with *Tao Ren Tang* (Apricot Kernel Decoction). The wet nurse must avoid raw, cold, greasy foods and all toxic substances for half a month.
[Zhang Huan] *Pi Xie Gao* (Evil-Expelling Ointment): Infants' blood and qi are not yet solid, and their spiritual energy is weak. Except for routine care by parents and wet nurses, do not let the child see strangers, nor carry them to other rooms/households, nor let them 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 carry coarse, violent qi from places visited by spirits/gods. If this qi invades the child, it causes vomiting and diarrhea of green, yellow, red, or white substances, separation of food and fluids, symptoms resembling epilepsy but without upward eye deviation or wiry-rapid pulse. This is named *Ke Wu*. (Weaned infants may also suffer sudden *Zhong E* (Struck by Evil); this medicine is suitable and can restore consciousness immediately.)
Ingredients: *Jiang Zhen Xiang* (Aquilaria Agallocha Resin), *Bai Jiao Xiang* (Liquidambar Resin), *Chen Xiang* (Agarwood), *Hu Tou Gu* (Tiger Skull Bone, lightly fried), *Gui Jiu* (Podophyllum Hexandrum Root), *Cao Long Dan* (Gentiana Scabra Root), *Renshen* (Ginseng), *Bai Fu Ling* (Poria).
Preparation: Each ingredient (half liang) is pounded and sifted into fine powder. Add half liang of *Xiong Huang* (Realgar) ground with water and floated (water-floating method). Grind 1 qian of *She Xiang* (Musk). Mix all uniformly. Blend with refined honey to form pills the size of a chicken head. Take one pill per dose, dissolved in *Ru Xiang Tang* (Frankincense Decoction). Additionally, make pills the size of a bullet, store in a green silk bag, and attach to the child's clothing. Burn incense regularly in the sleeping area.
[Tian] For *Ke Wu* causing shock/clashing: Use two liang of finely ground loam soil from the stove. Mix with one shelled egg and a little water. First bathe the child in peach and willow branch decoction, then apply this mixture to the five centers (palms, soles, chest) and the top of the head. (Chen Wuyue's method uses equal parts loam soil and earthworm feces applied similarly.)
For sudden *Ke Wu* with trismus and inability to speak: Equal parts *Xi Xin* (Asarum) and *Gui Xin* (Cinnamon Twig Heart), placed in the mouth. Effective.
*Yuan He Ji Yong Jing* treats infant *Ke Wu*: Crush *Chang Pu* (Acorus Tatarinowii Rhizome) juice and place in the mouth. Or use fresh *Ai Ye* (Mugwort Leaf) juice in the mouth. Or use 3-4 drops of knife-sharpening water; this is excellent. Or grind good ink, sieve it, mix with warm water, and take half a qian-bi.
