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)

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 bleeding does not stop, repeat the dose for cure. (Zhouhou Beiji Fang [Emergency Prescriptions Kept Up One's Sleeve] concurs)
