《病源论》云∶小儿在胎时，其母将养，伤于风冷，邪气入胞，伤儿脏腑。故儿生之后，
邪犹在儿腹内，邪动与正气相搏则腹痛，故儿 张蹙气而啼也。
《千金方》∶取新出马屎一丸，绞取汁，含之。
又方∶烧猪屎沸汤，淋取汁，浴之，并与少许饮之。
《病源论》云∶疟病者，夏伤于暑，至秋风邪乘之发。小儿未能触胃于暑亦病疟者，是
乳母抱持解脱，不避风也。
《千金方》∶生鹿角末，发先时便服一钱匕。
又方∶烧鳖甲，酒服方寸匕，至发时服三匕，并火灸身。
《葛氏方》云∶临发时，捣大附子，下筛和苦酒涂背上。
又方∶石上菖蒲浓煮，浴儿。（三四时亦佳也）。
今按∶《集验方》∶桃叶二七枚按心上，艾灸叶上十四壮。
《葛氏方》云∶恒山四分，小麦三合，淡竹叶切一升。上，以水三升，煮取一升，服之。
（今按∶《产经》云∶儿生四十余日至六十日者，分三服，或至百日服二合半，或于二百日
一服三合。）
《产经》云∶师左手持水碗，右持刀子，正面于北儿曰∶北斗七星，主知一切死生之命，
属北斗之君王某甲病疟，勿令流行。诵三遍讫，禹步就病儿前，令视碗中，师则吐呵，以其
持刀刺碗中儿影，急急如律令，勿令及顾。甚秘验，过病发后取刀子。（《范汪方》同之。）
又法∶头面胸背上皆笔作“天公”字，胸上书作咒日∶太山之下有不流水，上有神龙，
九头九尾；不食余物，正食疟鬼，朝食一千，暮食五百，一食不足，遣我来索。疟鬼闻之，
亡魄走行千里。用朱书之。
《诸病源候论》说：小儿在母胎中时，如果母亲调养不当，受到风冷邪气侵袭，邪气进入胞宫，损伤胎儿的脏腑。所以孩子出生后，邪气仍然留在孩子的腹内，当邪气活动与正气相互搏结时就引起腹痛，因此孩子会张大嘴巴、皱起眉头并啼哭。
《千金方》记载：取刚排出的马粪一丸，绞取汁液，让孩子含在口中。
另一个方子：将猪粪烧沸后用开水淋洗，取汁液给孩子洗澡，并喂服少量汁液。
《诸病源候论》说：疟疾病症，是因为夏季感受暑邪，到了秋天风邪乘虚而入而发作。小儿虽然未能直接感受暑邪却也得疟疾的，是因为乳母抱着孩子时疏忽大意，没有避开风邪所致。
《千金方》记载：取新鲜鹿角磨成的粉末，在发病前服用一钱匕（古代量器名）。
另一个方子：将鳖甲烧制后，用酒送服一方寸匕（古代量器名），到发病时服用三匕，同时对身体进行火灸。
《葛氏方》说：在即将发病时，捣碎大附子，过筛后与醋混合涂抹在背部。
另一个方子：用石菖蒲浓煎煮水，用来给孩子洗澡。（间隔三四小时也可以）。
现在考证：《集验方》记载：取十四片桃叶按在心口上，在桃叶上进行艾灸十四壮。
《葛氏方》说：恒山四分，小麦三合，切碎的淡竹叶一升。以上药材，用水三升，煮取一升药液，服用。
（现在考证：《产经》说：出生四十多天到六十天的婴儿，分三次服用；或者到一百天服用二合半；或者在二百天时一次服用三合。）
《产经》说：法师左手拿着水碗，右手拿着刀子，面朝北方对着孩子说：“北斗七星，主宰知晓一切生死命运，归属于北斗星君王某甲患疟疾，不要让病情蔓延。”念诵三遍结束后，施展禹步走到患病孩子面前，让孩子观看碗中的倒影，法师则吐气呵斥，手持刀刺向碗中孩子的影子，急急如律令，不要让邪气回头。非常秘密且有效，等病发过后才取下刀子。（《范汪方》与此相同。）
另一种方法：用笔在头部、面部、胸部和背部都写上“天公”二字，在胸口书写咒语说：“泰山之下有不流动的水，上面有神龙，九个头九条尾巴；不吃其他食物，专门吃疟鬼，早上吃一千个，晚上吃五百个，一顿不够，派我来索取。疟鬼听到后，魂魄逃散奔走千里。”用朱砂书写。
The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: When a child is in the womb, if the mother's care and nursing are improper, she may be injured by wind-cold pathogens. The pathogenic qi enters the uterus and damages the fetus's Zang-Fu organs. Therefore, after birth, the pathogenic qi remains within the child's abdomen. When the pathogenic qi moves and contends with the healthy qi, it causes abdominal pain, leading the infant to cry with an open mouth and furrowed brow.
The *Qianjin Fang* (Prescriptions Worth a Thousand Gold) records: Take one pellet of fresh horse manure, squeeze out the juice, and let the child hold it in the mouth.
Another prescription: Boil pig manure, pour boiling water over it to extract the liquid, use this liquid to bathe the child, and also give a small amount for drinking.
The *Zhubing Yuanhou Lun* states: Malaria (*Nue Bing*) arises from summer-heat injury in summer, which manifests when autumn wind-pathogens take advantage of the weakened state. If infants contract malaria without having directly encountered summer-heat, it is because the wet nurse holding the child was negligent and failed to avoid wind exposure.
The *Qianjin Fang* records: Take powder made from fresh deer horn and administer one *qianbi* (a spoon-like measure) before the onset of the disease.
Another prescription: Calcinate turtle shell, administer one *cunbi* (a square-inch measure) with wine; at the time of fever onset, administer three measures, and simultaneously apply moxibustion to the body.
The *Ge Shi Fang* (Formulas of Master Ge) states: At the time of impending attack, crush large *Fuzi* (Prepared Aconite Root), sieve it, mix with vinegar, and apply to the back.
Another prescription: Decoct *Shichangpu* (Rhizoma Acori Tatarinowii) thickly, and use the decoction to bathe the child. (An interval of three to four hours is also suitable.)
Current analysis: The *Jiyan Fang* (Collected Proven Prescriptions) records: Press fourteen peach leaves onto the heart region, and apply fourteen moxa cones on top of the leaves.
The *Ge Shi Fang* states: *Hengshan* (Radix Dichroae) 4 fen, wheat 3 he, and chopped *Dan Zhuye* (Caulis Bambusae in Taeniam) 1 sheng. Take these ingredients, add three sheng of water, boil down to one sheng, and administer.
(Current analysis: The *Chan Jing* (Classic of Childbirth) states: For infants aged forty to sixty days postpartum, divide into three doses; or for infants up to one hundred days, administer two and a half he; or for infants around two hundred days, administer three he in one dose.)
The *Chan Jing* states: The practitioner holds a bowl of water in the left hand and a knife in the right hand, faces north towards the child, and says: "The Big Dipper governs all life and death destinies. Belonging to the Lord of the Big Dipper, Wang Moujia suffers from malaria; do not let it spread." After reciting this three times, perform the Yu Bu (Step of Yu) ritual approach to the sick child, instructing the child to look into the bowl. The practitioner then exhales sharply and thrusts the knife into the child's reflection in the bowl, chanting "Ji Ji Ru Lü Ling" (Act swiftly as the law commands), preventing the pathogen from returning. This is highly secret and effective; remove the knife only after the paroxysm has passed. (This matches the *Fan Wang Fang*.)
Another method: Write the characters "Tian Gong" (Heavenly Duke) on the head, face, chest, and back using a brush. On the chest, write a spell saying: "Beneath Mount Tai flows stagnant water, above which resides a divine dragon with nine heads and nine tails. It eats no other food, but specifically consumes malaria ghosts, eating one thousand in the morning and five hundred in the evening. If one meal is insufficient, I am sent to claim more. Upon hearing this, malaria ghosts flee their souls and run for a thousand li." Use cinnabar ink for writing.
