痢疾不问赤白，皆属湿热，或以赤为热。白为寒者。非也，
亦有食积而成者。其治法有补有泄。赤白湿热皆有，但热症腹
痛，湿症腹不痛。
凡痢有赤，此湿热伤在血分，从小肠中来也。以四物汤加黄
连。黄芩、黄柏治之。
凡痢有白者，此湿热在气分，从大肠中来也。以四君子汤加
黄连、苍术治之。
凡赤白相杂者，此血气俱伤。以八物汤加黄连、黄芩、黄
柏、苍术、滑石治之。以上三症，有后重者，俱加槟榔，枳实。
凡治痢疾，不问赤白。但初起之时，里急后重，腹中胀痛
者，先用三黄丸。大承气汤下之，后用香连丸调之。
凡痢赤白日久，人事虚弱，原未经下者，若下之，则人事
虚，而不可损其不足;若不下。则积未去而难愈。只用保和丸，
连服数次，俟腹止痛为度，后以香连丸调之。
凡治痢不可妄用巴豆、牵牛，只用三黄丸稳当。

凡赤白痢脱肛者，此气下陷也。宜升提之，和中丸以升麻汤
吞之。
凡赤白痢呕吐不食者。此名噤口痢，用木香则失之温，用山
药则失之闭，只以参苓白术散，石菖蒲末，陈米饮调下，胸次
一开，自然思食。
凡痢止后，身热不退，或人事瘦弱者，只用集圣丸调之。
痢疾不分赤白，都属于湿热证；认为红色属热、白色属寒的观点是错误的。也有因食积而形成的痢疾。其治疗方法有补法也有泻法。赤白相兼的痢疾中，湿热皆有，但热症表现为腹痛，湿症则腹部不痛。
凡是痢疾见红色的，这是湿热损伤了血分，病源来自小肠。用四物汤（Four-Item Decoction）加黄连、黄芩、黄柏治疗。
凡是痢疾见白色的，这是湿热在气分，病源来自大肠。用四君子汤（Four-Gentlemen Decoction）加黄连、苍术治疗。
凡是赤白相杂的痢疾，这是气血都受了损伤。用八物汤（Eight-Item Decoction）加黄连、黄芩、黄柏、苍术、滑石治疗。以上三种病症，如果有里急后重（tenesmus）症状的，都要加槟榔、枳实。
凡是治疗痢疾，不分赤白。但在初起之时，出现里急后重、腹部胀痛的症状，先用三黄丸（Three-Yellow Pill）、大承气汤（Major Order the Yang Decoction）攻下，后用香连丸（Fragrant Coptis Pill）调理。
凡是痢疾赤白日久，人体正气虚弱，原本没有经过攻下治疗的，如果此时攻下，会使人体更虚，不可再损伤其不足的正气；如果不攻下，则积滞未去而难以痊愈。只用保和丸（Preserve Harmony Pill），连续服用数次，等到腹痛停止为止，然后用香连丸调理。
凡是痢疾带有鲜血的，用清血丸（Clear Blood Pill），用车前草、陈米煎汤送服。
凡是痢疾带有白涎，久治不止的，用固肠丸（Secure Intestine Pill），用陈米饮送服。
凡是暑月痢疾纯下鲜血的，用益元散（Benefit the Primordial Powder）、炒过的滑石，加红曲制成丸剂，用陈米饮送服。
凡是赤白痢导致脱肛的，这是气机下陷所致。应当升提气机，用和中丸（Harmonize the Middle Pill）配合升麻汤吞服。
凡是赤白痢伴有呕吐、不能进食的，这名叫噤口痢（Jinkou Dysentery）。用木香则过于温燥，用山药则容易闭门留寇（导致闭塞），只用参苓白术散（Ginseng, Poria, and Atractylodes Macrocephala Powder）加石菖蒲末，用陈米饮调服，胸膈通畅后，自然就会想吃饭。
Dysentery, regardless of whether it is red or white, belongs to damp-heat syndrome; the view that red indicates heat and white indicates cold is incorrect. There are also cases caused by food stagnation. The treatment methods include tonification and purgation. In dysentery with both red and white discharge, both dampness and heat are present, but heat syndrome presents with abdominal pain, whereas dampness syndrome does not present with abdominal pain.
Whenever there is red discharge in dysentery, this indicates that damp-heat has injured the blood level (xue fen), originating from the Small Intestine. It is treated with Siwu Tang (Four-Item Decoction) added with Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), and Huangbai (Phellodendri Cortex).
Whenever there is white discharge in dysentery, this indicates that damp-heat is at the qi level (qi fen), originating from the Large Intestine. It is treated with Sijunzi Tang (Four-Gentlemen Decoction) added with Huanglian (Coptidis Rhizoma) and Cangzhu (Atractylodis Rhizoma).
Whenever there is a mixture of red and white discharge in dysentery, this indicates that both qi and blood are injured. It is treated with Bawu Tang (Eight-Item Decoction) added with Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Huangbai (Phellodendri Cortex), Cangzhu (Atractylodis Rhizoma), and Huashi (Talcum). For the above three conditions, if there is tenesmus, Binglang (Arecae Semen) and Zhishi (Aurantii Fructus Immaturus) should be added to all formulas.
In treating dysentery, regardless of red or white discharge: if at the initial stage there is tenesmus and abdominal distension and pain, first administer Sanhuang Wan (Three-Yellow Pill) and Dachengqi Tang (Major Order the Yang Decoction) to purge, followed by Xianglian Wan (Fragrant Coptis Pill) for regulation.
If dysentery with red and white discharge has persisted for a long time and the patient's vital energy is weak, and no purgation has been used previously: if purgation is now applied, it will further weaken the patient, which is contraindicated as it damages what is already insufficient; if purgation is not applied, the pathogenic accumulation remains and recovery is difficult. Use Baohe Wan (Preserve Harmony Pill) only, administered continuously several times until abdominal pain ceases, then regulate with Xianglian Wan (Fragrant Coptis Pill).
When treating dysentery, one must not recklessly use Badou (Crotonis Fructus) or Qianniu (Pharbitidis Semen); using Sanhuang Wan (Three-Yellow Pill) is safer.
For dysentery with fresh blood, use Qingxue Wan (Clear Blood Pill), taken down with decoction of Cheqiancao (Plantaginis Herba) and aged rice water.
For dysentery with white mucus that persists for a long time, use Guchang Wan (Secure Intestine Pill), taken down with aged rice water.
For pure bloody dysentery occurring in summer months, use Yiyuan San (Benefit the Primordial Powder) and stir-fried Huashi (Talcum), mixed with Hongqu (Red Yeast Rice) to form pills, taken down with aged rice water.
For prolapse of the rectum due to red and white dysentery, this is due to sinking of qi. It should be lifted and raised; Hezhong Wan (Harmonize the Middle Pill) is swallowed with Shengma Tang (Cimicifugae Decoction).
For red and white dysentery accompanied by vomiting and inability to eat, this is called Jinkou Li (Jinkou Dysentery). Using Muxiang (Aucklandiae Radix) is too warming, while using Shanyao (Dioscoreae Rhizoma) causes closure; instead, use Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) mixed with Shichangpu (Acori Tatarinowii Rhizoma) powder, taken down with aged rice water. Once the chest and diaphragm open up, appetite will naturally return.
After dysentery stops, if fever persists or the patient becomes emaciated and weak, use Jisheng Wan (Collect the Sage Pill) for regulation.
