血痢腹痛者，火也。方用∶
归尾（一两） 白芍（一两） 黄连（三钱） 枳壳（二钱） 木香（二钱） 萝卜子（二钱） 甘草（一钱）
水煎服。
血痢腹不痛者，寒也。方用∶
当归（三钱） 白芍（三钱） 槟榔（一钱） 枳壳（一钱） 萝卜子（一钱） 甘草（一钱）
水煎服。
前方治壮实之人，火邪挟湿者。此方治寒痢腹不痛者〔血痢虽有痛、不痛之分，其实火邪，而挟湿气也。
论理二方俱可通用，而分痛、不痛，乃慎之也。二方出入减，各为神效，正不必畏首畏尾，一用之于痛，一用之于
不痛也。盖火邪滞湿气于肠脾之际，不得奔下，未有不里急而后重也。妙在用当归、白芍而利之，则火邪利于直
下，不止平肝木而救脾土也。〕
此症感湿热而成，红白相见，如脓如血，至危至急者也。苟用凉药止血，热药攻邪，俱非善治之法。方用∶
当归（二两） 白芍（二两） 槟榔（二钱） 枳壳（二钱） 广木香（一钱） 萝卜子（一钱） 甘草（二钱） 滑
石（三钱）
水煎服。
一、二剂收功。此方妙在用归、芍二两之多，则肝血有余，不去克脾土，自然大肠有传送之功。加之枳壳、槟榔、
萝卜子，俱逐秽去积之品，尤能于补中用攻。而滑石、甘草、木香，调达于迟速之间，不疾不缓，使瘀滞
尽下也。其余些小痢疾，只用减半治之，无不奏功。此方不论红白痢疾，痛与不痛，服之皆神效。
又方∶
当归（一两） 黄芩（七钱） 苍术（一钱） 浓朴（一钱） 陈皮（一钱） 大腹皮（一钱）
水二樽，煎一樽，顿服。
血痢伴有腹痛的，是火邪所致。方剂如下：
当归尾（一两） 白芍（一两） 黄连（三钱） 枳壳（二钱） 木香（二钱） 萝卜子（二钱） 甘草（一钱）
用水煎服。
血痢腹部不痛的，是寒邪所致。方剂如下：
当归（三钱） 白芍（三钱） 槟榔（一钱） 枳壳（一钱） 萝卜子（一钱） 甘草（一钱）
用水煎服。
前一方适用于身体壮实、火邪夹杂湿气的人。此方适用于寒痢且腹部不痛的人。（虽然血痢有疼痛和不疼痛的区别，但实质都是火邪夹杂湿气。从理论上讲，两个方子都可以通用，区分疼痛与不疼痛是为了更加谨慎。两个方子在药物加减上各有神效，确实不必畏首畏尾，一个用于疼痛，一个用于不疼痛。因为火邪阻滞湿气在肠脾之间，导致大便不能顺畅排出，没有不出现里急后重症状的。妙在用当归、白芍来疏利，使火邪得以直下，这不仅平抑肝木，还能救助脾土。）
这种病症是由感受湿热而成，红白相兼，状如脓血，属于极其危险紧急的病证。如果使用凉药止血，或用热药攻邪，都不是良好的治疗方法。方剂如下：
当归（二两） 白芍（二两） 槟榔（二钱） 枳壳（二钱） 广木香（一钱） 萝卜子（一钱） 甘草（二钱） 滑石（三钱）
用水煎服。
一至两剂即可见效。此方的妙处在于使用多达二两的当归和白芍，使得肝血充足，不再克制脾土，大肠自然恢复传导功能。再加上枳壳、槟榔、萝卜子，这些都是祛除污秽积滞的药物，尤其能在补益中运用攻伐之法。而滑石、甘草、木香，则在快慢之间起到调和作用，不急不缓，使瘀滞之物全部排出。其余轻微的痢疾，只需将剂量减半治疗，无不奏效。此方不论红白痢疾，也不论疼痛与否，服用都有神效。
另一个方剂：
当归（一两） 黄芩（七钱） 苍术（一钱） 厚朴（一钱） 陈皮（一钱） 大腹皮（一钱）
水两碗，煎成一碗，一次性服用。
Dysentery with blood and abdominal pain is caused by Fire pathogen. The prescription is as follows:
Dangguiwei (Radix Angelicae Sinensis Cauda, 1 liang) Baishao (Radix Paeoniae Alba, 1 liang) Huanglian (Rhizoma Coptidis, 3 qian) Zhike (Fructus Aurantii Immaturus, 2 qian) Muxiang (Radix Aucklandiae, 2 qian) Luobozizi (Semen Raphani, 2 qian) Gancao (Radix Glycyrrhizae, 1 qian)
Decoct in water and take orally.
Dysentery with blood but without abdominal pain is caused by Cold pathogen. The prescription is as follows:
Danggui (Radix Angelicae Sinensis, 3 qian) Baishao (Radix Paeoniae Alba, 3 qian) Binglang (Arecae Semen, 1 qian) Zhike (Fructus Aurantii Immaturus, 1 qian) Luobozizi (Semen Raphani, 1 qian) Gancao (Radix Glycyrrhizae, 1 qian)
Decoct in water and take orally.
The former prescription treats robust individuals where the Fire pathogen is accompanied by Dampness. This prescription treats cold dysentery with no abdominal pain. [Although bloody dysentery is divided into painful and non-painful types, essentially both involve the Fire pathogen accompanied by Dampness. Theoretically, both prescriptions can be used interchangeably; distinguishing between pain and no pain is for greater caution. Both prescriptions are highly effective with minor modifications, so there is no need to hesitate excessively; one is used for pain, and the other for no pain. When the Fire pathogen stagnates Dampness at the junction of the intestines and spleen, preventing smooth downward movement, tenesmus (li ji hou zhong) invariably occurs. The brilliance lies in using Danggui and Baishao to promote free flow, allowing the Fire pathogen to descend directly, which not only soothes the Liver Wood but also nourishes the Spleen Earth.]
This condition arises from contracting Damp-Heat. It presents with red and white discharge mixed together, resembling pus and blood, and is extremely critical and urgent. Using cooling herbs to stop bleeding or hot herbs to attack pathogens are both not good treatment methods. The prescription is as follows:
Danggui (Radix Angelicae Sinensis, 2 liang) Baishao (Radix Paeoniae Alba, 2 liang) Binglang (Arecae Semen, 2 qian) Zhike (Fructus Aurantii Immaturus, 2 qian) Guangmuxiang (Radix Aucklandiae, 1 qian) Luobozizi (Semen Raphani, 1 qian) Gancao (Radix Glycyrrhizae, 2 qian) Huashi (Talcum, 3 qian)
Decoct in water and take orally.
One or two doses will achieve the result. The brilliance of this prescription lies in using a large amount (2 liang each) of Danggui and Baishao, ensuring sufficient Liver Blood so that it does not overact upon the Spleen Earth, thereby naturally restoring the conduction function of the Large Intestine. Added to this are Zhike, Binglang, and Luobozizi, all substances that expel filth and accumulate debris, particularly capable of employing attacking methods within tonification. Meanwhile, Huashi, Gancao, and Muxiang harmonize the pace, neither too fast nor too slow, ensuring all stagnation is expelled. For milder cases of dysentery, simply halving the dosage yields excellent results. This prescription is highly effective regardless of whether the dysentery is red or white, painful or painless.
Another prescription:
Danggui (Radix Angelicae Sinensis, 1 liang) Huangqin (Radix Scutellariae, 7 qian) Cangzhu (Rhizoma Atractylodis Lanceae, 1 qian) Houpo (Cortex Magnoliae Officinalis, 1 qian) Chenpi (Pericarpium Citri Reticulatae, 1 qian) Dafupi (Pericarpium Arecae, 1 qian)
Use two bowls of water, decoct until one bowl remains, and take in one dose.
