病因：这是由于肠胃虚弱，受到风邪侵袭，从而形成痢疾夹杂热邪。热邪侵入血分，导致血液渗入肠道，与痢疾之物混杂而下，因此出现赤痢。（出自第十七卷）

Etiology: This arises from the weakness of the intestines and stomach, injured by wind-pathogens, resulting in dysentery complicated with heat. When heat invades the blood level, blood permeates into the intestines, mixing with the dysenteric discharge and being expelled downward. Thus, red dysentery occurs. (From Volume 17)

All consumed foods... (Text fragment follows)

Soak the Xiangdanchi in one and a half sheng of water for one day. Filter to obtain the juice. Crush the Huanglian, wrap it in thin silk, and decoct it in the danchi juice until reduced to slightly more than half a sheng. Take on an empty stomach in one dose; it will be effective immediately. Jiang Wei, Magistrate of Sangquan, stated it was effective. (From Volume 2)

By evening, the red dysentery should turn white, and recovery will occur the next morning. (From Volume 3)
Etiology: Chronic red dysentery results from bodily deficiency, where heat invades the blood, causing blood to seep into the intestines, hence the red stool. The intestines and stomach are weak and fail to return to normal; the heat does not subside, leading to chronic non-resolution. If stomach qi rebels upward, it transforms into vomiting and hiccups. If stomach deficiency leads to衰弱的 grain qi, parasites move and invade the flesh, transforming into... (Text fragment). (From Volume 17)

If not cured, take rainwater dripping from the eaves, filter out impurities, and drink one sheng, twice daily. Gujin Luyan prescribes drinking a small cup of eaves water, with the rest of the method being the same. This refers to Xu Pingfang's treatment of hematochezia lasting twenty years. If bleeding does not stop, repeat the dose for cure. (Zhouhou Beiji Fang [Emergency Prescriptions Kept Up One's Sleeve] concurs)
