小儿患客忤病，是因为小儿的神气稚嫩虚弱。忽然遇到不寻常的事物，或是未曾见过的人，偶然被其触动或看见，外来的客气与小儿的神气相互冲撞从而引发疾病，这称为客忤。其症状表现为呕吐和腹泻青色、黄色或白色的物质，水谷分离，腹部疼痛且身体扭曲挣扎，面色改变，五色无常，状似惊痫，但眼球不上翻。脉象弦急而数，这就是客忤病的特征。如果不立即治疗，时间久了就难以治愈。《圣济经》说：起居作息不合时宜，会导致客忤病，告诫人们要警惕因见到不寻常的人物而致病。《千金方》说：小儿的衣物、丝绵絮以及鞋袜中，都不能含有头发，所有不认识的人物从外来者，都应当让小儿避开不要看见。如果误被触犯，都会导致小儿患上客忤病。如果有患病的情况，必须迅速查看小儿口中悬雍垂（小舌）的左右两侧，若有如麻豆大小的肿胀硬结，就必须用针挑破使其溃烂。用丝绵缠绕钗头，拭去血液，同时服用各种药物进行治疗。
治疗小儿客忤引起的腹痛、身体扭曲挣扎、面色改变。用香豉数合，用水拌湿，捣熟做成丸子，大小如鸡蛋。用来摩擦小儿囟门（头顶软处），以及手足心各七遍，并摩擦小儿心口和肚脐，上下往返摩擦。过一顿饭的时间，便将药丸丢弃在道路中间，疼痛随即停止。
治疗小儿突然遭受客忤的涂敷法。取灶中的黄土和蚯蚓粪等量，研成细末，用水调匀后涂抹在小儿头上，以及五个手心（两手心、两脚心、心口）效果很好。
另一种洗浴法。治疗方法同上。用马粪三升，烧至烟尽，加入酒三升，煮沸数次后滤去渣滓。用此液给小儿洗浴。或者用猪粪二升，用热汤浇灌搅拌，待温度适宜后给小儿洗浴。
又一方。治疗小儿客忤的服用方法。用牛口中的唾液涂抹在乳汁上喂给小儿。
又一方。将铜镜的鼻钮烧得通红，放入酒中。能喝药的让小儿自己喝，不能喝的含着药液灌入。
治疗小儿患客忤，呕吐青白色泡沫，以及乳汁食物全部吐出，腹中疼痛，气息微弱欲绝的情况。用桂心一两研成粉末。对于一至百天的婴儿，取半钱药末，用水一小盏，煎至五分，滤去渣滓。温服，分四次服用，不拘泥于具体时间。根据小儿的大小增减剂量。
又一方。治疗小儿客忤。用白僵蚕七枚研成粉末，用酒调服半钱至一钱。
又一方。治疗方法同上。取书虫（书中白鱼）十枚，敷在乳头上，让小儿吮吸服用。（今人称之为衣鱼）。
又一方。治疗方法同上。取驴的乳汁，少量多次喂服。或者取一块热的马粪，绞取汁液饮用，咽下即愈。
麝香乳
治疗客忤导致的项部僵硬、痛苦欲死。取少许麝香研细，用乳汁调匀涂抹在小儿口中，如大豆大小，效果良好。
又一方。治疗方法同上。将桔梗烧成粉末，取半钱用酒调服。根据年龄大小增减剂量。
治疗马毒客忤。在马面前烧马尾，让小儿吸入烟气。每日使用，直至痊愈。
辟邪膏
治疗客忤，以及治疗中恶邪厉鬼气。其症状类似惊痫，但眼球不上翻也不倒视，脉象弦急。若是突然中邪，服用此药可立即苏醒。
真降香（锉碎）、白胶香（单独研磨）、沉香、虎头骨（用酥炙至黄色）、鬼臼（去毛）、龙胆草（去芦头）、人参（去芦头）、白茯神（去心及内部木心，各半两）。
以上药材研成细末。其次加入研磨过筛的雄黄末半两，研磨细的麝香一钱，拌匀。用炼蜜调和制成如鸡头米大小的丸子。每次服用一粒，用煎好的乳香汤化开送服。另外制作如弹子大小的丸子，用绿色绢袋盛装，挂在小儿衣服上佩戴。
Pediatric patients suffering from *Ke Wu* (Guest Hostility) do so because their *Shen Qi* (Spiritual Energy) is tender and weak. Suddenly encountering unusual objects or unfamiliar people, and accidentally being touched by or seeing them, causes external *Ke Qi* (Guest Energy) to clash with the child's *Shen Qi*, thereby generating disease. This is called *Ke Wu*. The manifestations include vomiting and purging of green, yellow, or white substances, separation of water and grain, abdominal pain with twisting and writhing (*Yao Jiao*), alteration of facial complexion, irregularity of the five colors, a condition resembling *Jing Xian* (Startled Epilepsy), but without upward deviation of the eyes. The pulse is wiry, rapid, and tense; this is *Ke Wu*. If not treated immediately, it becomes difficult to cure after a long time. *Sheng Ji Jing* states: "Irregular daily routines lead to *Ke Wu*," warning against illness caused by seeing unusual figures. *Qian Jin Fang* states: "Children's clothing, silk floss, and shoes/socks must not contain hair. All unfamiliar persons coming from outside should be kept away from the child's sight. Accidental contact will cause *Ke Wu*." If a child falls ill due to such contact, one must urgently examine the left and right sides of the *Xuan Yong* (Uvula) in the child's mouth. If there are swollen nodules the size of hemp seeds or beans, they must be pricked to induce suppuration. Wrap the head of a hairpin with cotton, wipe away the blood, and administer various herbal medicines for treatment.
To treat pediatric *Ke Wu* causing abdominal pain, twisting/writhing, and altered complexion: Take several *He* (a unit of volume) of fermented soybeans (*Xiang Chi*), moisten them with water, pound until cooked/soft, and form into pills the size of chicken eggs. Rub these on the child's fontanelle (anterior fontanelle), as well as on the palms of hands and soles of feet, seven times each. Also rub the child's chest (heart area) and umbilicus, moving up and down. After the duration of a meal, discard the pill on the road; the pain will then cease.
For treating sudden onset of *Ke Wu* in children, apply the following paste: Mix equal parts of loess soil from the hearth and earthworm feces. Grind into fine powder, mix with water, and apply to the child's head and the "five centers" (two palms, two soles, and chest). This is highly effective.
Another bathing method: Treat as above. Use three *Sheng* (a unit of volume) of horse manure, burn until smoke ceases, add three *Sheng* of wine, boil several times, strain. Bathe the child with this liquid. Alternatively, use two *Sheng* of pig manure, pour hot water over it and stir. When warm enough, bathe the child.
Another prescription for administering treatment for pediatric *Ke Wu*: Apply saliva from a cow's mouth onto breast milk and feed the child.
Another prescription: Heat the nose/boss of a bronze mirror until red-hot, place it in wine. Let the child drink if able; otherwise, hold the liquid in the mouth and force-feed.
To treat pediatric *Ke Wu* where the child vomits green and white foam, expels all milk and food, suffers abdominal pain, and has breath nearly failing: Take one *Liang* (unit of weight) of *Gui Xin* (Cinnamon Heart/Cortex Cinnamomi), grind into powder. For infants aged one to one hundred days, take half a *Qian* (unit of weight). Add one small cup of water, decoct until reduced to five *Fen* (units of volume), strain. Warm and divide into four doses. Administer at any time, adjusting dosage according to the child's age and size.
Another prescription for pediatric *Ke Wu*: Take seven dried silkworms (*Bai Jiang Can*), grind into powder, and take half to one *Qian* mixed with wine.
Another prescription: Treat as above. Take ten booklice (white fish found in books, now known as *Yi Yu*), apply to the nipple, and let the child suck and swallow.
Another prescription: Treat as above. Give donkey milk in small amounts. Or, take a piece of hot horse dung, squeeze out the juice, and have the child drink it; healing occurs upon swallowing.
*Moxiang Ru* (Musk Milk):
Treats *Ke Wu* causing neck stiffness and extreme distress. Take a small amount of *Mo Xiang* (Musk), grind finely, mix with milk, and smear inside the child's mouth, about the size of a soybean. Effective.
Another prescription: Treat as above. Burn *Jie Geng* (Platycodon Root) to ash, take half a *Qian*, mix with wine and administer. Adjust dosage based on age.
Treating Horse-Toxin *Ke Wu*: Burn horse tail hairs in front of the child's face. Let the child inhale the smoke. Use daily until recovered.
*Bixie Gao* (Evil-Expelling Ointment):
Treats *Ke Wu*, as well as *Zhong E* (Sudden Evil Attack) caused by malevolent spirits. Symptoms resemble epilepsy but without upward or backward deviation of the eyes; the pulse is wiry and tense. In cases of sudden attack, it restores consciousness immediately.
Ingredients: *Zhen Jiang Xiang* (Agarwood/Dalbergia Odorifera - sliced), *Bai Jiao Xiang* (Benzoin Resin - ground separately), *Chen Xiang* (Aquilaria Wood), *Hu Tou Gu* (Tiger Skull Bone - fried with butter until yellow), *Gui Jiu* (Podophyllum Peltatum - de-haired), *Long Dan Cao* (Gentiana Root - de-rhizome), *Ren Shen* (Ginseng Root - de-rhizome), *Bai Fu Shen* (Poria with Hostwood - de-heart and internal wood, 0.5 *Liang* each).
Grind the above into fine powder. Then add 0.5 *Liang* of refined and sieved *Xiong Huang* (Realgar Powder) and 1 *Qian* of finely ground *Mo Xiang* (Musk). Mix well. Blend with refined honey to form pills the size of a cockle seed. Take one pill per dose, dissolve in decoction of *Ru Xiang* (Frankincense) soup. Additionally, make pills the size of a bullet, store in a green silk bag, and carry on the child's clothing.
