《巢氏病源》小儿疟后内热渴引饮候∶疟病者，是夏伤于暑，热客皮肤，至秋复为风邪所折，阴阳交争，故
发寒热成疟。凡疟发欲解则汗，汗则津液减耗，又热成于脏，脏虚燥，其疟瘥之后，腑脏未和，津液未复，故
内犹热，渴而引饮也。若引饮不止，小便涩者，则变成癖也。
《婴童宝鉴》小儿疟后渴并有块歌∶
疟瘥因何渴，皆因脏腑虚；热存犹饮水，结块腹中居。

《巢氏病源》小儿疟后胁内结硬候∶疟是夏伤于暑，热客于皮肤，至秋复为风邪所折，阴阳交争，故发寒热。
其病正发寒热交争之时，热气乘脏，脏则燥而渴，渴而引饮；饮停成癖，结于胁下。故瘥之后胁内结硬也。

《巢氏病源》中关于小儿疟疾后内热口渴引饮的证候：患疟疾的人，是因为夏季感受暑邪，热气客居在皮肤之间，到了秋季又受到风邪的遏制，导致阴阳之气相互交争，所以出现寒热交替的症状而形成疟疾。凡是疟疾发作将要解除时会有汗出，出汗则导致津液减少耗损，加上体内脏腑产生热邪，脏腑虚弱且干燥，所以在疟疾痊愈之后，腑脏功能尚未调和，津液尚未恢复，因此体内仍然有热，感到口渴而想要饮水。如果饮水不止，小便涩滞不畅，则会转变为癖积（腹内结块）。
《婴童宝鉴》中关于小儿疟疾后口渴并伴有腹中结块的歌诀：
疟疾痊愈后为何还会口渴？都是因为脏腑虚弱；余热留存所以想喝水，结块停留在腹部之中。
《圣惠方》治疗小儿疟疾发作时间不固定，多伴有心烦口渴的乌梅散方：
乌梅肉（半两，轻微炒制） 常山（一两） 甘草（三分，炙至微红，切碎）
将上述药物捣碎，粗筛成散剂。每次服用一钱，用水一小盏，加入淡竹叶七片、小麦三十粒，共同煎煮至剩余五分药液，滤去药渣，温服。根据患儿年龄大小酌情增减剂量服用。
《圣惠方》治疗七八岁小儿患疟疾，寒热往来，心烦或口渴的干漆散方：
干漆（捣碎，炒至烟出） 川大黄（切碎，轻微炒制。各一分） 常山 石膏（一两，研细） 甘草（半两，炙至微红，切碎）
将上述药物捣碎，粗筛成散剂。每次服用一钱，用水一小盏，加入小麦三十粒，煎煮至剩余五分药液。滤去药渣放温，在疟疾发作前服用。根据患儿年龄大小酌情增减剂量。
《巢氏病源》中关于小儿疟疾后胁下内部结硬的证候：疟疾是夏季感受暑邪，热气客居在皮肤，到了秋季又受到风邪的遏制，阴阳交争，所以出现寒热症状。当疾病正处于寒热交争之时，热气侵袭脏腑，脏腑就会干燥而口渴，口渴而大量饮水；饮水停滞形成癖积，结聚在胁下。所以在疟疾痊愈之后，胁下内部会出现结硬的现象。
《葛氏肘后方》治疗六七岁小儿心腹坚硬痞块，时常出现如疟疾般的寒热症状，服用紫丸六十天经过吐下治疗后，痞块仍然坚硬，用鸡蛋汤一剂，排出恶物数升后痊愈。使用此法神效。
甘遂（七铢） 甘草（炙） 黄芩（各五钱）
以上药物用水二升半，鸡蛋一枚，轻轻敲开取出蛋清投入水中，充分搅拌后吹去泡沫滤去杂质。放入药物煮取一升药液，根据小儿年龄大小，计算可服用的剂量，分几次给予服用。此药无毒，能引起腹泻排出痞块，若痞块未尽可再次服用。如果痞块坚实较多者，增加黄芩、细辛各一两，效果极佳。
《婴孺书》治疗小儿疟疾经久不断，停止后又复发；胁下有痞块坚硬如手的方子。
芫花（炒制） 朱砂（各二分）
将上述药物研为末，用蜂蜜制成丸剂。二百日大的婴儿服用黍米大小的丸药，每日两次。若无效稍加剂量。
《婴孺书》治疗婴幼儿疟疾伴有痞块，坚硬满闷的癖疾，具有清热降气作用的知母丸方：
知母 甘草（炙） 常山（各一两） 麻黄（二两，去节）
将上述药物研为末，用蜂蜜和匀制成如小豆大小的丸剂。每次服用五丸，每日三次。直到即将发作时，三服药服完即可。非发作日期也可以服用。如果增加大黄一两，能够治疗骨间热、睡眠不安的症状。
According to *Chao Shi Bing Yuan* (Source of Diseases by Chao Yuanfang) regarding the syndrome of internal heat, thirst, and excessive drinking in children after malaria: Patients with malaria suffer from summerheat contracted in summer, where heat resides in the skin. In autumn, this is constrained by wind pathogens, causing a struggle between Yin and Yang, resulting in alternating chills and fever, thus forming malaria. When malaria is about to resolve, sweating occurs; sweating leads to the depletion of body fluids. Additionally, heat generates within the Zang organs, making them deficient and dry. After the malaria subsides, the Fu and Zang organs are not yet harmonized, and body fluids have not recovered. Therefore, internal heat remains, causing thirst and a desire to drink. If drinking continues excessively and urination becomes difficult and scanty, it transforms into *Pi* (accumulation masses).
The song from *Ying Tong Bao Jian* (Precious Mirror for Infants and Children) regarding thirst and abdominal masses in children after malaria:
Why does thirst persist after malaria resolves? It is due to the deficiency of the Zang and Fu organs; residual heat remains, prompting water intake, while masses form and reside in the abdomen.
*Sheng Hui Fang* (Prescriptions of Holy Grace) formula Wumei San (Mume Powder) for treating irregularly occurring malaria in children accompanied by frequent thirst and mental restlessness:
Wumei Mei Rou (Semen Pruni Mume, half tael, lightly stir-fried); Changshan (Radix Dichroae, one tael); Gancao (Radix Glycyrrhizae, three fen, honey-fried until slightly red, chopped).
Crush the above ingredients and sieve coarsely to make a powder. Take one qian per dose, decoct with one small cup of water, adding seven leaves of Dan Zhuye (Herba Lophatheri) and thirty grains of Xiaomai (Frumentum Tritici) until reduced to five fen. Strain and take warm. Adjust dosage according to the child's age.
*Sheng Hui Fang* formula Ganxi San (Dried Lacquer Powder) for treating seven- or eight-year-old children suffering from malaria with alternating chills and fever, mental restlessness, or thirst:
Ganxi (Resina Rhois Verniciferae, crushed and stir-fried until smoke emerges); Chuan Dahuang (Radix et Rhizoma Rhei, chopped and lightly stir-fried; each one fen); Changshan (Radix Dichroae); Shigao (Gypsum Fibrosum, one tael, ground); Gancao (Radix Glycyrrhizae, half tael, honey-fried until slightly red, chopped).
Crush the above ingredients and sieve coarsely to make a powder. Take one qian per dose, decoct with one small cup of water and thirty grains of Xiaomai (Frumentum Tritici) until reduced to five fen. Strain, let cool to warm, and administer before the onset of malaria. Adjust dosage according to the child's age.
According to *Chao Shi Bing Yuan* regarding the syndrome of hardness in the hypochondrium after malaria in children: Malaria results from summerheat contracted in summer, residing in the skin, and being constrained by wind pathogens in autumn, causing a struggle between Yin and Yang, leading to chills and fever. During the peak of chills and fever struggle, heat attacks the Zang organs, causing dryness and thirst, leading to excessive drinking. Stagnant fluid forms *Pi* (accumulations), knotting under the hypochondrium. Thus, after recovery, hardness persists inside the hypochondrium.
*Ge Shi Zhou Hou Fang* (Emergency Prescriptions Kept in the Sleeve of the Master Ge) for treating six- or seven-year-old children with hard epigastric and abdominal masses, intermittent chills and fever resembling malaria. After taking Zi Wan (Purple Pill) for sixty days inducing vomiting and purging, if the mass remains hard, administer one dose of Jizi Tang (Egg White Decoction), expelling several sheng of foul matter, resulting in cure. This method is miraculous.
Gansui (Radix Kansui, seven zhu); Gancao (Radix Glycyrrhizae, honey-fried); Huangqin (Radix Scutellariae, five qian each).
Use two and a half sheng of water and one egg. Gently crack the egg, pour out the white into the water, stir well, blow away foam, and strain. Add the herbs and boil to obtain one sheng of liquid. Administer in divided doses according to the child's age and tolerance. The medicine is non-toxic and induces purging of the mass. If the mass is not fully expelled, repeat administration. For hard and numerous masses, add Huangqin (Radix Scutellariae) and Xixin (Radix Asari), one tael each, for excellent effect.
*Ying Ru Shu* (Book for Infants and Toddlers) formula for treating prolonged, recurrent malaria in children with hard, hand-like masses under the hypochondrium:
Yuanhua (Flos Genkwa, stir-fried); Zhusha (Cinnabar, two fen each).
Grind into powder, mix with honey to form pills. For infants around two hundred days old, make pills the size of millet seeds; administer twice daily. Increase dosage slightly if ineffective.
*Ying Ru Shu* formula Zhimu Wan (Anemarrhenae Pill) for treating pediatric malaria with masses, hard and full accumulation diseases, clearing heat and directing Qi downward:
Zhimu (Rhizoma Anemarrhenae); Gancao (Radix Glycyrrhizae, honey-fried); Changshan (Radix Dichroae; each one tael); Mahuang (Herba Ephedrae, two liang, remove joints).
Grind into powder, mix with honey to form pills the size of small beans. Take five pills per dose, three times daily. Continue until just before the next attack, completing three doses. Can also be taken on non-attack days. If Dahuang (Radix et Rhizoma Rhei) one tael is added, it can treat heat in the bones and restless sleep.
