客忤者。口中吐青黄白沫。水谷鲜杂。面色变异。喘息腹痛。反侧螈 。状似惊痫

客忤者。谓客气忤犯主气之病也。如五气之邪。自鼻而入。则忤其心肝。五味之邪。自
入。则忤其脾胃。有所惊恐。则忤其神。有所拂逆。则忤其意。当博求之。故曰。心诚求之

一儿半岁。忽日惨然不乐。昏睡不乳。予曰。形色无病。将谓外感风寒。则无外感之证。将
谓内伤乳食。则无内伤乳食之证。此儿莫非有所思。思则伤脾。乃昏睡不乳也。其父母悟云
。有一小 相伴者。吾使他往。今三日矣。乳母亦云。自小 去后。便不欣喜。不吃乳。父
急命呼之归。儿见其童嘻笑。父曰。非翁之妙术。不能知也。
一儿一岁。啼哭不止。予审察之。非病也。其父母曰。无病何以啼哭异常。予问其乳母
。此儿平日戏玩者何物。乳母曰。马鞭子。即以取至。儿见大笑。击人而哭止。
一儿九月。吐乳便黄。身有微热。予曰。此伤热乳也。吐作腥气。今已成积。母曰。未
物。予密语其父曰。必伤交奶得之。父问何谓交奶。予曰。父母交感之后。以乳哺儿。此淫
火之邪。忤脾胃正气也。不治之必成癖矣。何以致。曰。淫火者。肝火也。病则发搐。癖者
脾病也。积不消则为癖。父问何以治之。曰泻肝补脾。乃以泻火胃苓丸服之。
客忤病，表现为口中吐出青、黄、白色的泡沫，混杂着未消化的食物残渣，面色发生异常改变，伴有喘息和腹痛，身体翻动抽搐，症状类似惊痫。但眼球不会向上窜视。治疗方法应当以辟除邪气、扶助正气、驱散惊恐、安定神志为主。主方选用苏合丸或至圣保命丹。
所谓客忤，是指外来的客气（邪气）冲犯人体主气所导致的疾病。例如五气之邪从鼻窍进入，就会冲犯心肝；五味之邪从口摄入，就会冲犯脾胃；受到惊吓，就会冲犯心神；遇到违逆之事，就会冲犯意志。对此应当广泛探究其病因。所以说：“用心真诚地去探求，即使不能正中靶心，也不会相差太远。”详细内容详见《育婴家秘》。
有一个半岁的婴儿，忽然神情凄惨不快乐，昏睡且拒绝吃奶。我诊察后说：孩子的神色形态没有生病的迹象。如果说他是外感风寒，却没有外感风寒的症状；如果说他是内伤乳食，也没有内伤乳食的症状。这个孩子莫非是有所思虑？思虑过度会损伤脾脏，所以导致昏睡拒奶。他的父母醒悟过来，说：“有一个小童陪伴他，我派他出去了，已经三天了。”乳母也说，自从那个小童离开后，孩子就不再高兴，也不吃奶。父亲急忙派人叫那孩子回来。孩子见到同伴嬉笑玩耍，父亲感叹道：“如果不是您的高明医术，无法得知病因。”
有一个一岁的孩子，啼哭不止。我仔细审察，认为并非生病。他的父母问：“没病为什么啼哭得如此异常？”我问乳母：“这孩子平时玩什么玩具？”乳母说：“马鞭子。”于是让人拿来马鞭，孩子看见后大笑，拍打他人，啼哭随即停止。
有一个九个月大的婴儿，吐奶且大便发黄，身体有轻微发热。我说：“这是伤了热乳所致。”呕吐物带有腥气，现在已经形成了积滞。母亲说：“喂奶前并未进食其他食物。”我私下对父亲说：“这一定是因为‘交奶’（指父母行房事后立即哺乳）导致的。”父亲问什么是“交奶”。我说：“父母行房事之后，立即用乳汁喂养婴儿。这是淫火之邪，冲犯了脾胃的正气。”如果不治疗，必然形成癖块（腹内结块）。为什么会这样呢？我说：“淫火，指的是肝火。肝火发病则会出现抽搐；癖，是脾的病证。积滞不消除就会形成癖块。”父亲问如何治疗。我说：“需要泻肝火、补脾气。”于是服用泻火胃苓丸进行治疗。
Ke Wu (Guest Intrusion) is characterized by the expulsion of green, yellow, and white froth from the mouth, mixed with undigested food residues. The facial complexion changes abnormally, accompanied by panting, abdominal pain, body turning and convulsions, resembling Jing Xian (Startling Epilepsy). However, the eyes do not roll upward. The treatment method should focus on dispelling evil qi, supporting righteous qi, scattering fright, and calming the spirit. The principal formulas are Su He Wan (Styrax Pill) or Zhi Sheng Bao Ming Dan (Supreme Sage Life-Preserving Pill).
Ke Wu refers to a disease caused by external guest qi (pathogenic factors) invading and offending the host qi. For instance, the pathogenic factors of the Five Qi entering through the nose will offend the Heart and Liver; the pathogenic factors of the Five Flavors entering through the mouth will offend the Spleen and Stomach; being startled will offend the Shen (Spirit); encountering contrariety will offend the Yi (Intent). One should extensively investigate the etiology. Thus it is said: "If one sincerely seeks the cause, even if one does not hit the mark exactly, one will not be far off." For details, see *Yu Ying Jia Mi*.
A six-month-old infant suddenly appeared miserable and unhappy, sleeping deeply and refusing breast milk. I examined him and said: "The child's color and form show no signs of illness. If we attribute it to Exogenous Wind-Cold, there are no exogenous symptoms; if we attribute it to Internal Injury from Milk and Food, there are no internal injury symptoms. Could this child be preoccupied with thoughts? Overthinking injures the Spleen, leading to lethargy and refusal to nurse." His parents realized and said, "There was a young boy accompanying him, whom I sent away three days ago." The wet nurse also stated that since that boy left, the child had become unhappy and refused milk. The father urgently ordered the boy to be called back. Upon seeing the companion playing and laughing, the father remarked, "Without your profound medical skill, this cause could not have been known."
A one-year-old child cried incessantly. After careful examination, I determined it was not an illness. The parents asked, "Why is he crying so abnormally if he is not ill?" I asked the wet nurse, "What toys does this child usually play with?" She replied, "A horsewhip." The whip was brought forth, and upon seeing it, the child laughed heartily, slapped others, and his crying stopped.
A nine-month-old infant vomited milk, had yellow stools, and presented with slight fever. I said, "This is due to injury from hot milk. The vomit has a fishy odor, and accumulation has already formed." The mother said, "No other food was consumed before nursing." I whispered to the father, "This must be caused by 'Jiao Nai' (nursing immediately after parental intercourse)." The father asked what 'Jiao Nai' meant. I explained, "After parents engage in sexual intercourse, breastfeeding the infant immediately introduces the pathogenic factor of Yin Fire, which offends the Righteous Qi of the Spleen and Stomach. If untreated, it will inevitably lead to Pi Masses (abdominal masses). Why is this so? Yin Fire refers to Liver Fire. When Liver Fire manifests, it causes convulsions. Pi is a disease of the Spleen. Accumulation that does not dissipate becomes Pi Masses." The father asked how to treat it. I said, "One must drain the Liver and tonify the Spleen." Therefore, Xie Huo Wei Ling Wan (Fire-Draining Stomach-Ling Decoction) was administered.
