春伤于风，邪气留连，遇肠胃虚弱，风邪因而伤之，肠虚则泄，故为下痢，然此水谷利痢也。
冷热不调，肠虚者，冷热之气客于其间。热气乘之则赤，冷气乘之则白，冷热相交连滞
，故赤白如鱼脑鼻涕相杂，为滞利也。
妊娠经血不通，上为乳法，兼以养胎。若宿有停饮者，则血饮相搏，又因冷热不调，动
于血饮，血饮乘气逆上，抢于胸胁，胸胁胀满，而气小喘，谓之支满。
水饮停积，结聚为痰，人皆有之。少者不能为害，若多则成病，妨害饮食，乃至呕吐。
妊娠病之，若呕吐甚者，伤胎也。
脏虚而热气乘于心，则令心烦；停痰积饮，在于心胸，其冲于心者，亦令烦也。若虚热
而烦者，但烦热而已；若有痰饮而烦者，则呕吐涎沫。妊娠之人，既血饮停积，或虚热相搏
，故亦烦。以其妊娠而烦，故谓之子烦也。
阴阳清浊相干，谓之气乱，气乱于肠胃之间，为霍乱也。但饮食过度，冒触风冷，使阴
阳不和，致清浊相干，肠胃虚者受之，故霍乱也。先心痛则先吐，先腹痛则先利，心腹俱痛
有头痛体疼，发热而吐痢者，亦为霍乱。所以然者，挟风而有实故也。风折血气，皮肤
闭密，血气不得宣，故令壮热；风邪乘其经脉，气上冲于头，则头痛；风气入于肠胃，肠虚
则泄痢，胃逆则呕吐，故吐痢也。吐痢甚则烦，腑脏虚故也。又手足逆冷，阳气暴竭，谓之
四逆也。妊娠而病之，吐痢甚者，则伤损胎也。
Wind pathogen acquired in spring lingers and, encountering weak intestines and stomach, invades the body. When the intestines are deficient, diarrhea occurs, resulting in dysentery; this is classified as a type of diarrhea involving undigested food and water.
When cold and heat are imbalanced and the intestines are weak, cold and heat pathogens lodge within. Heat invading results in red stools, while cold invading results in white stools. The intermingling and stagnation of cold and heat cause the stools to appear mixed with red and white substances resembling fish brains or nasal mucus, which is termed "stagnant dysentery" (Zhi Li).
During pregnancy, menstrual blood ceases to flow downward and instead nourishes the breasts and supports the fetus. If there is pre-existing retained fluid (Phlegm-Fluid), it may contend with blood. Combined with cold-heat imbalance, this disturbs the blood and fluids, causing them to rebel upward along with Qi, striking the chest and hypochondrium. This leads to distension and fullness in the chest and hypochondrium, accompanied by shortness of breath, a condition known as "Zhi Man" (Supporting Fullness).
Retained fluids accumulate and condense into phlegm, a phenomenon present in everyone. In small amounts, it causes no harm; in large amounts, it becomes pathological, obstructing digestion and potentially leading to vomiting. If a pregnant woman suffers from this, severe vomiting can damage the fetus.
Visceral deficiency allows heat to invade the Heart, causing mental restlessness (Fan Xin). Retained phlegm and fluids lodged in the chest and heart region, when they surge upward affecting the Heart, also cause restlessness. Restlessness due to deficiency-heat manifests merely as feverish irritability; restlessness due to phlegm-fluids is accompanied by vomiting of saliva and foam. Pregnant women, having accumulated blood and fluids or experiencing contention between deficiency-heat, often suffer from restlessness. Since this occurs during pregnancy, it is called "Zi Fan" (Fetal Restlessness).
The interference between Yin-Yang and clear-turbid Qi is termed Qi disorder. When Qi becomes chaotic between the intestines and stomach, it constitutes Huoluan (Cholera-like syndrome). Overeating or exposure to wind-cold can disrupt Yin-Yang harmony, causing clear and turbid Qi to mix. When weak intestines and stomach are affected, Huoluan ensues. If heart pain precedes, vomiting occurs first; if abdominal pain precedes, diarrhea occurs first. If both heart and abdomen hurt, accompanied by headache, body ache, fever, vomiting, and diarrhea, it is also Huoluan. This occurs because the condition involves wind pathogens and excess pathogens. Wind constrains Blood and Qi, closing the skin pores, preventing their free circulation, thus causing high fever. Wind pathogen invading meridians causes Qi to rush upward to the head, resulting in headache. Wind entering the intestines and stomach causes diarrhea due to intestinal weakness and vomiting due to rebellious Stomach Qi. Severe vomiting and diarrhea lead to restlessness due to visceral deficiency. Additionally, cold extremities indicate sudden exhaustion of Yang Qi, termed "Si Ni" (Four Rebellions/Cold Extremities). If a pregnant woman contracts this disease and experiences severe vomiting and diarrhea, the fetus will be damaged.
