霍乱者，阴阳清浊二气相干，谓之气乱，气乱于肠胃之间，为霍乱也。小儿肠胃嫩弱，
因解脱逢风冷，乳哺不消，而变吐痢也。或乳母触冒风冷，食饮生冷物，皆冷气流入乳，令
乳变败，儿若饮之，亦成霍乱吐痢。皆是触犯腑脏，使清浊之气相干，故霍乱也。挟风而络
实者，则身发热，头痛体疼，而复吐痢。
凡小儿霍乱，皆须暂断乳，亦以药与乳母服，令血气调适，乳汁温和故也。小儿吐痢不
止，血气变乱，即发惊痫也。
吐痢者，由肠虚而胃气逆故也。小儿有解脱，而风冷入肠胃，肠胃虚则泄痢，胃气逆则
呕吐。此大体与霍乱相似而小轻，不剧闷顿，故直云吐痢，亦不呼为霍乱也。
春夏以汤下小儿，其肠胃脆嫩，不胜药势，遂吐下不止；药气熏脏腑，乃烦懊顿乏者，
谓此为中毒，毒瓦斯吐下也。
儿啼未定，气息未调，乳母匆遽以乳饮之，其气尚逆，乳不得下，停滞胸膈，则胸满气
急，令儿呕逆变吐。
又，乳母将息取冷，冷气入乳，乳变坏，不捻除之，仍以饮儿，冷乳入腹，与胃气相逆
，则腹胀痛，气息喘急，亦令呕吐。
又，解脱换易衣裳及洗浴，露儿身体，不避风冷，风冷因客肤腠，搏血气则热，入于胃
，则腹胀痛而呕逆吐也。凡如此，风冷变坏之乳，非直令呕吐，肠虚冷入于大肠，则为痢也
霍乱，是指阴气与阳气、清气与浊气相互干扰，称为气机紊乱。气在肠胃之间发生紊乱，就形成了霍乱。小儿的肠胃娇嫩虚弱，如果脱衣受风着凉，乳汁无法消化，就会转变为呕吐和泄痢。或者乳母受到风冷侵袭，食用生冷食物，冷气流入乳汁，导致乳汁变质，婴儿若饮用这种变质的乳汁，也会形成霍乱引起的呕吐和泄痢。这些都是因为触犯了腑脏，使清浊之气相互干扰，从而产生霍乱。如果兼夹风邪且络脉充实，就会出现身体发热、头痛、肢体疼痛，并伴有呕吐和泄痢的症状。
凡是小儿患霍乱，都必须暂时停止哺乳，同时也让乳母服药，以使气血调和，乳汁温和。小儿呕吐泄痢不止，会导致气血紊乱，进而引发惊痫（惊风抽搐）。
吐痢（呕吐和泄痢），是由于肠道虚弱而胃气上逆造成的。小儿如果脱衣受风冷入侵肠胃，肠道虚弱则导致泄痢，胃气上逆则导致呕吐。这种情况大体上与霍乱相似但程度较轻，没有严重的烦闷昏厥，所以直接称为吐痢，也不称之为霍乱。
春夏季节用汤药给小儿服药，因其肠胃脆嫩，承受不住药力，于是出现呕吐泄痢不止；药气熏蒸脏腑，导致心中烦闷懊恼、精神困乏，这被称为中毒，即毒气通过呕吐和泄痢排出体外。
婴儿啼哭未定，气息尚未平稳，乳母匆忙地喂以乳汁，此时婴儿的气机尚处于上逆状态，乳汁无法下行，停滞在胸膈部位，就会导致胸部胀满、呼吸急促，引起婴儿呕逆呕吐。
另外，乳母调养时贪凉，冷气进入乳汁，使乳汁变质，如果不剔除清除，仍然喂给婴儿，冷乳进入腹部，与胃气相逆，就会导致腹胀痛、呼吸喘急，也会引起呕吐。
还有，婴儿脱衣换裳及洗浴时，暴露身体，不躲避风冷，风冷邪气客居于皮肤腠理，搏结血气而生热，热气进入胃中，就会导致腹胀痛以及呕逆呕吐。凡此种种，被风冷变坏的乳汁，不仅会引起呕吐，如果肠虚寒冷之邪侵入大肠，就会形成泄痢。
Huo luan (acute vomiting and diarrhea) refers to the mutual interference of Yin and Yang, clear and turbid Qi, termed Qi disorder. When Qi becomes disordered between the intestines and stomach, it constitutes Huo luan. Children's intestines and stomach are tender and weak; if they expose themselves to wind-cold after undressing, and milk fails to digest, it transforms into vomiting and dysentery. Alternatively, if the nursing mother is exposed to wind-cold or consumes cold raw foods, cold Qi flows into the milk, causing the milk to spoil. If the infant drinks this spoiled milk, it also results in Huo luan with vomiting and dysentery. All these cases involve offending the fu organs, causing clear and turbid Qi to interfere with each other, thus generating Huo luan. If accompanied by wind pathogen and excess in the collaterals, there will be fever, headache, body pain, along with vomiting and dysentery.
For any pediatric case of Huo luan, breastfeeding must be temporarily suspended. Medication should also be administered to the nursing mother to regulate Qi and blood, ensuring the milk remains mild and warm. If a child suffers from incessant vomiting and dysentery, Qi and blood become chaotic, leading to the onset of jing xian (convulsions).
Vomiting and dysentery arise from deficiency in the intestines and rebellious Qi in the stomach. If children expose themselves to wind-cold after undressing, cold pathogens enter the intestines and stomach. Intestinal deficiency leads to diarrhea and dysentery, while gastric Qi rebellion leads to vomiting. This condition is generally similar to Huo luan but milder, lacking severe distress and collapse, hence it is directly termed "vomiting and dysentery" and not referred to as Huo luan.
In spring and summer, when decoctions are given to children, their fragile and tender intestines and stomachs cannot withstand the potency of the medicine, resulting in incessant vomiting and diarrhea. The medicinal Qi steams the zang-fu organs, causing mental restlessness, vexation, and exhaustion; this is termed poisoning, where toxic vapors are expelled through vomiting and diarrhea.
When an infant is still crying and breathing has not yet regulated, if the nursing mother hastily provides breast milk, the infant's Qi is still rebellious. The milk fails to descend and stagnates in the chest and diaphragm, causing chest fullness and rapid breathing, leading to vomiting and regurgitation.
Furthermore, if the nursing mother indulges in cold during recuperation, cold Qi enters the milk, spoiling it. If this is not removed and the infant is still fed, the cold milk enters the abdomen, conflicting with gastric Qi. This causes abdominal distension and pain, rapid breathing, and also induces vomiting.
Additionally, when infants undress, change clothes, or bathe, exposing their bodies without avoiding wind-cold, wind-cold pathogens lodge in the skin and interstices. They contend with Qi and blood, generating heat. When this heat enters the stomach, it causes abdominal distension, pain, and vomiting. In all such cases, milk spoiled by wind-cold not only causes vomiting; if intestinal deficiency allows cold to enter the large intestine, it results in dysentery.
