Treats bloody dysentery and regulates Qi, addressing painful urination and stools containing pus and blood. Understanding that when Qi moves, blood stops flowing abnormally, the stool will naturally heal; regulating Qi eliminates the sensation of tenesmus (feeling of incomplete defecation).

Bai Shao (Paeoniae Radix Alba) (1 liang), Dang Gui (Angelicae Sinensis Radix), Huang Lian (Coptidis Rhizoma), Huang Qin (Scutellariae Radix) (each 5 qian), Guan Gui (Cinnamomi Cortex) (2.5 qian), Bing Lang (Arecae Semen), Da Huang (Rhei Radix et Rhizoma) (each 3 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma) (roasted), Mu Xiang (Aucklandiae Radix) (each 2 qian).
Take 5 qian per dose, decoct in water. If dysentery does not subside, gradually increase the dosage of Da Huang. If it is Zang Du (visceral toxin, referring to dysentery caused by damp-heat and toxic pathogens accumulating in the viscera) after sweating, add Huang Bo (Phellodendri Cortex).

Another prescription: Treats Jin Kou Li (Jin Kou Dysentery, a type of dysentery where the patient cannot eat due to rebellious Stomach Qi), with reliable efficacy.
Lu Jiao (Cervi Cornus Degelatinati) 2 liang, calcined to retain its nature, ground into powder. Adults take 3 qian, children take 1 qian, mixed with wine and taken orally. One can eat within one shi (two hours).

Another prescription: Treats Chi Li (red dysentery) and Jin Kou Li, suitable for cases with excessive Yang toxicity. Use one bowl of wine, add 3 qian of Huang Lian stir-fried with ginger, decoct, and take warm on an empty stomach.

Umbilical therapy treats chronic toxic heat dysentery that persists, accompanied by vomiting, nausea, inability to eat, rising hot qi, leading to an inability to eat (Jin Kou). Take one field snail, crush it whole with the shell, add a small amount of She Xiang (Moschus), apply inside the umbilicus, and seal externally with a plaster.

Mu Xiang (3 qian), Qing Pi (Citri Reticulatae Pericarpium Viride) (remove pith, 6 qian), Sha Ren (Amomi Fructus) (24 grains), Ba Dou (Crotonis Fructus) (21 grains, pierced with a needle and burned over a lamp until retaining its nature), Xing Ren (Armeniacae Semen Amarum).
Grind the above herbs into powder. Ba Dou and Xing Ren are ground separately, then mixed evenly. Melted wax is used to form pills. When needed, roll them into pills the size of hemp seeds. Take 10 to 25 pills per dose, adjusting according to the patient's age and deficiency/excess condition. For red dysentery, take with Gan Cao Tang (Licorice Decoction); for white dysentery, take with Gan Jiang Tang (Dried Ginger Decoction); for both red and white dysentery, take with Gan Cao Gan Jiang Tang (Licorice and Dried Ginger Decoction). Avoid raw, cold, greasy, and oily foods.

Huang Lian (Coptidis Rhizoma) (remove roots, clean, and finely chopped) 20 liang, mix with 10 liang of Wu Zhu Yu (Evodiae Fructus), cover with a small amount of boiling water and let stand for one fu shi (four hours), then stir-fry together until fragrant and cooked. Remove from heat,
grind into fine powder and mix evenly. Use egg white with a little vinegar as a binder to make pills the size of paulownia seeds. Take 50 pills per dose, with plain boiled water.

For those without sweat, induce sweating; the primary method is to disperse pathogenic factors, supplemented by tonification. For those with sweat, stop sweating; the primary method is to support healthy Qi, supplemented by dispersing. The pulse in malaria is mostly wiry (Xian). A wiry and rapid pulse indicates heat; a wiry and slow pulse indicates cold. In prolonged illness, the pulse may be extremely deficient, appearing slightly wiry but not striking the fingers upon palpation, though careful observation may reveal it. A wiry pulse like the edge of a knife indicates death (poor prognosis); a wiry and small pulse indicates life (good prognosis).
