薛氏治一小儿，每饮食失节，或外惊所忤，即吐泻发搐，服镇惊化痰等药而愈。后发搐益甚，
饮食不进，虽参术之剂，到口即呕。余用白术和土炒黄，用米泔煎数沸，不时灌半匙，仍呕。次日灌之，微呕。再
日灌之，
欲呕。此后每服二三匙，渐加至半杯，不呕，乃浓煎服而愈
一、小儿泻而大便热赤，小便涩少，此热蕴于内也。先以四苓散加炒黄连一剂，其热顿退。又
用七味白术散去木香二剂，热渴顿止。后以四君、升麻调理而痊。
一、小儿九岁，会炙爆之物，作泻饮冷，诸药不应，肌体消瘦，饮食少思。余用黄连一两，酒
拌炒焦为末，入人参末四两，粥丸小豆大，每服四五十丸，不拘时，白汤下，服讫渐愈。又用五味
异功散加升麻，服月余而瘥。后不戒浓味，患疳积，消瘦少食，发热作渴，用大芦苍丸为主，以四
味肥儿丸为佐，疳证渐退。却以四味肥儿丸为主，以五味异功散为佐而痊。后又不禁浓味，作泻饮
冷，仍服肥儿丸、异功散而瘥。
小儿霍乱吐泻者，必以寒凉伤胃，或时气阴湿，或饮食失宜，皆能致之。然此与前吐泻并行者
，稍有不同。盖霍乱者，暴而甚；吐泻者，徐而缓。霍乱者，伤在一时，吐泻者，其伤以渐，此其
所以有异也。若暴疾霍乱而胃口未清，胸腹仍满者，宜先用和胃饮，苓术二陈煎，或大、小和中饮
，或小厘清饮，或神香散之类主之。俟胃口稍平，即宜五味异功散，或温胃饮、五苓散之类调补之
。若霍乱初起便觉神疲气倦，而胃口别无胀滞者，此其胃气已伤，即宜温补，如养中煎、温胃饮之
类，不得概行清利也。
薛氏治疗一名小儿，每当饮食不节制，或因外界惊吓所扰，就会发生呕吐、腹泻并伴有抽搐，服用镇惊化痰等药物后痊愈。后来抽搐症状加重，饮食无法进服，即使是人参、白术类的药剂，入口即吐。我使用白术与灶心土同炒至黄色，用米泔水煎煮数沸，不时灌入半匙，患儿仍然呕吐。第二天再次灌服，出现轻微呕吐。又过一天灌服，仅有想吐的感觉。此后每次服用二三匙，逐渐增加至半杯，不再呕吐，于是浓煎服用而痊愈。
其一，小儿腹泻且大便热赤，小便涩少，这是热邪蕴结于体内。先用四苓散加入炒黄连一剂，其热势顿时消退。接着使用七味白术散去木香两剂，热渴顿时停止。随后以四君子汤、升麻调理而康复。
其二，一名九岁小儿，因食用烤爆之物，又泻下时饮用冷水，各种药物均无效，身体消瘦，食欲不振。我使用黄连一两，酒拌炒焦研为细末，加入人参末四两，用米粥制成如小豆大小的丸药，每次服用四五十丸，不限时间，用白开水送服，服药后逐渐好转。又使用五味异功散加升麻，服用月余而病愈。后来不能节制浓味食物，患上疳积，身体消瘦，进食减少，发热口渴，以大芦苍丸为主药，以四味肥儿丸为辅药，疳证逐渐消退。转而以四味肥儿丸为主药，以五味异功散为辅药而痊愈。后来又不能节制浓味食物，导致腹泻并饮用冷水，仍服用肥儿丸、异功散而病愈。
小儿霍乱吐泻，必定是因为寒凉损伤胃气，或受时令之气阴湿影响，或饮食不当，都能导致此病。然而这与前述的呕吐和腹泻同时进行的病症略有不同。所谓霍乱，发病急骤且病情严重；所谓吐泻，发病缓慢且病情较轻。霍乱是伤于一时之间，吐泻则是逐渐受损，这就是它们的不同之处。如果是暴发的霍乱，但胃脘口尚未清净，胸腹部仍然胀满的，适宜先用和胃饮、苓术二陈煎，或者大、小和中饮，或小厘清饮，或者神香散之类的方剂主治。等到胃口稍微平稳，就应当使用五味异功散，或者温胃饮、五苓散之类的方剂进行调补。如果是霍乱初起便感觉精神疲倦、气息乏力，而胃口没有胀滞感的，这是胃气已经受伤，就应当立即温补，如养中煎、温胃饮之类的方剂，不得一概使用清热利湿的方法。
Dr. Xue treated a pediatric patient who, whenever his diet was irregular or he was startled by external stimuli, would experience vomiting, diarrhea, and convulsions. He recovered after taking medicines for calming fright and resolving phlegm. Later, the convulsions worsened, and he could not eat; even decoctions containing Ginseng Radix (Renshen) and Atractylodis Macrocephalae Rhizoma (Baizhu) caused immediate vomiting upon ingestion. I used Rhizoma Atractylodis Macrocephalae (Baizhu) stir-fried with kitchen earth until yellow, boiled it in rice-washing water for a few minutes, and administered half a spoonful at intervals. The child still vomited. On the second day, slight vomiting occurred. On the third day, only the urge to vomit remained. Thereafter, each dose of two or three spoonfuls was gradually increased to half a cup without causing vomiting, after which a concentrated decoction was taken, leading to recovery.
One case involved a child with diarrhea characterized by hot, red stools and scanty, difficult urination, indicating heat accumulation internally. Initially, Siling San (Four-Ingredient Powder) added with stir-fried Coptidis Rhizoma (Huanglian) was administered for one dose, resulting in an immediate reduction of heat. Subsequently, Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Powder) with the removal of Aucklandiae Radix (Muxiang) was given for two doses, stopping the heat and thirst abruptly. Finally, Sijunzi Tang (Four-Gentlemen Decoction) combined with Cimicifugae Rhizoma (Shengma) was used for regulation, leading to full recovery.
Another case involved a nine-year-old child who developed diarrhea after consuming roasted and fried foods and drinking cold liquids during the diarrheal episode. Various medications were ineffective, resulting in emaciation and poor appetite. I used Liangdang Huanglian (Coptidis Rhizoma, Huanglian) one liang, mixed with wine and stir-fried until charred, then ground into powder. Four liang of Ginseng Radix (Renshen) powder was added, and the mixture was formed into pills the size of adzuki beans using congee. Each dose consisted of 40–50 pills, taken at any time with plain warm water. Gradual improvement followed. Then, Wuwei Yigong San (Five-Ingredient Extraordinary Efficacy Powder) with added Cimicifugae Rhizoma (Shengma) was administered for over a month, leading to recovery. Later, due to lack of dietary restraint regarding rich flavors, the child developed Gji syndrome (malnutrition syndrome), with emaciation, reduced food intake, fever, and thirst. Dalu Cang Wan (Large Reed and Cangzhu Pill) was used as the primary formula, assisted by Siwei Fei'er Wan (Four-Ingredient Child-Nourishing Pill), leading to the gradual subsidence of the Gji symptoms. Subsequently, Siwei Fei'er Wan became the primary formula, assisted by Wuwei Yigong San, resulting in recovery. Again, due to inability to restrain rich food intake, diarrhea ensued with consumption of cold drinks; treatment with Fei'er Wan and Yigong San led to recovery.
Pediatric Huoluan (cholera-like disorder) with vomiting and diarrhea is invariably caused by cold-cold damaging the stomach, seasonal dampness, or improper diet. However, this differs slightly from the simultaneous occurrence of vomiting and diarrhea discussed previously. Huoluan is sudden and severe, whereas vomiting and diarrhea are gradual and mild. Huoluan results from injury occurring instantaneously, while vomiting and diarrhea involve progressive damage. If acute Huoluan presents with an uncleaned stomach gate and persistent chest/abdominal fullness, Hewei Yin (Harmonize the Stomach Drink), Lingzhu Erchen Jian (Poria and Atractylodes Macrocephala and Two-Aged Decoction), Da Zhonghe Yin (Major Harmonizing Middle Drink), Xiao Zhonghe Yin (Minor Harmonizing Middle Drink), Xiao Liqing Yin (Minor Clearing Drink), or Shenxiang San (Aromatic Sandalwood Powder) should be used primarily. Once the stomach gate stabilizes, Wuwei Yigong San (Five-Ingredient Extraordinary Efficacy Powder), Wenwei Yin (Warm the Stomach Drink), or Wuling San (Five-Ingredient Powder for Promoting Urination) should be used for tonification and regulation. If Huoluan begins with fatigue and qi deficiency, but without gastric distension or stagnation, it indicates injury to stomach qi, requiring immediate warming and tonification such as Yangzhong Jian (Nourish the Center Decoction) or Wenwei Yin (Warm the Stomach Drink); clearing and draining methods should not be applied indiscriminately.
