《千金》论曰∶凡诸乘马行，得马汗气臭，未盥洗易衣装，而便向儿边，令儿中马客忤。儿卒见马来，及闻
马鸣惊，及马上衣物、马气，皆令小儿中马客忤。慎护之，特重一岁儿也。
《圣惠》∶凡人乘马到人家，人身有马汗不暇汤浴，则须换衣服。不暇换衣服即食顷间歇定，方得亲近小儿。
若不如此，则小儿中马毒客忤。或初卸马，马气未歇，将鞍辔等物逼近小儿，儿闻马嘶便惊，皆因中马毒客忤。
其状腹痛，吐下青黄白色，水谷解离，甚者致夭也。
《千金》治小儿中马客忤法（中客、中人皆可用∶）
用粉为丸如豉法，摩儿手足心及心头脐上下，行转摩之。咒曰∶摩家公摩家母，摩家子儿苦客忤，从我始，
扁鹊虽良不如善唾良。咒讫，弃丸道中。
《千金》又法∶
取一刀横着灶上，解儿衣，发其心腹讫（《千金翼》以发字作拨。）取刀持向儿吮之唾，辄以刀拟向
心腹，啡啡曰（音非，
出唾貌）∶煌煌日，出东方，背阴向阳。葛公、葛公，不知何公（《千金翼》云∶葛公、葛母，不
知何公。）子来不视，去罔顾，过与
生人忤。梁上尘，天之神。户下土，鬼所经。大刀锾犀对灶君，二七唾客愈儿惊。唾啡啡，如此二七啡啡。每
唾以刀拟之咒。当三遍乃毕。用豉丸亦如上法，五、六遍讫。取此丸破视，其中有毛，弃丸道中，人马客忤即
愈矣。
《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。
《圣惠》又方
上取马口角沫，涂儿口中效。
Qianjin Fang (Essential Prescriptions Worth a Thousand Gold) states: Whenever people ride horses, they may be contaminated with the foul odor of horse sweat. If one has not washed hands, changed clothes, or shoes, and then approaches an infant, it may cause the infant to suffer from "Ma Ke Wu" (a pediatric condition caused by the shock or toxic qi of horses). When infants suddenly see horses, are startled by horse neighing, or come into contact with horse tack and horse odors, all these can cause children to suffer from "Ma Ke Wu". Careful protection is required, especially for infants under one year of age.
Taiping Shenghui Fang records: When a person rides a horse to another's home and carries horse sweat on their body without having time for a bath, they must change their clothes. If changing clothes is not feasible, they should rest for a while until their breath and spirit settle before approaching the child. Otherwise, the child may contract "Ma Du Ke Wu" (pediatric condition caused by horse toxicity). Or, immediately after unloading the saddle, when the horse's odor has not dissipated, bringing items like saddles and bridles close to the child, causing the child to be startled by the sound of horse neighing, are all due to contracting "Ma Du Ke Wu". The symptoms include abdominal pain, vomiting and diarrhea of green, yellow, or white stool, separation of water and grain in the digestive tract, and in severe cases, death.
The method in Qianjin Fang for treating pediatric Ma Ke Wu (applicable to both Ma Ke Wu and Ren Ke Wu):
Make pills using rice flour, sized like soybeans. Rub them on the palms of the infant's hands, soles of the feet, the heart region, and above and below the umbilicus, rubbing back and forth. Chant the spell: "Master Mo, Mistress Mo, the child suffers from Ke Wu, starting with me; although Bian Que was skilled, spitting well is superior." After chanting, discard the pill on the road.
Another method in Qianjin Fang:
Place a knife horizontally on the stove. Undress the infant to expose the chest and abdomen (in Qianjin Yi Fang, the character "fa" is written as "bo"). Hold the knife towards the infant and spit into your mouth, then point the knife at the heart and abdomen while making the sound "fei fei" (pronounced "fei", describing the action of spitting), saying: "The bright sun rises in the east, turning away from yin towards yang. Ge Gong, Ge Gong, I do not know which Gong. The child comes but does not look, leaves without looking back, passing through conflict with the living. Dust on the beams is the dwelling of heavenly spirits; earth under the door is where ghosts pass. The great sword and rhino horn face the Kitchen God; fourteen spits cure Ke Wu and calm the child's fright. Spit 'fei fei', just like this fourteen times 'fei fei'. Each spit must be accompanied by pointing the knife and chanting. This should be repeated three times to complete. Using the Dou pill follows the same method, repeated five to six times. Take this pill and break it open to inspect; if there is hair inside, discard the pill on the road, and the Ma/Ren Ke Wu will be cured."
Jianyao Jizhong Fang treats pediatric Ma Du Ke Wu by burning horse tail hairs in front of the infant, allowing the infant to inhale the smoke, burning daily until recovery.
Another prescription in Taiping Shenghui Fang:
Scrape the foam from the corners of the horse's mouth and apply it to the infant's mouth; this is effective.
