寒泻一名 溏。其原为脾气衰弱，及寒气在下，遂致水粪并趋大肠，色多青黑，宜温之。
春夏宜用∶
川桂枝 白芍药 白术各半两 甘草（炙）二钱
水煎服。
秋冬宜用∶
白芍药 白术各三钱 干姜（炮）半两 甘草（炙）二钱
水煎服。甚者则除去干姜加附子三钱。
热泻者，夏月热气，乍乘太阴，与湿相合；如水之注，故一名暴泻。其候腹痛自汗，烦
渴面垢，脉洪数或虚，肛门热痛，粪出如汤。方用∶
香薷一斤 白扁豆半斤（微炒） 浓朴（去皮姜汁炙熟）半斤
上研末，每服三钱，水煎服。
久泻不止，由于有陈积在肠胃之间，积一日不去，则泻一日不止。治宜先去陈积，而后
补之。方用∶
浓朴 干姜 甘草 桂心 附子各二两 大黄四钱
上细锉，先以前五味用水二升半煎八合，并将大黄切碎，水一碗渍半日，煮汤与前汁相
合，再煎取六和，去滓，分三服，一日服尽。
肾泄者，五更溏泄也。其原为肾阳虚亏，既不能温养于脾，又不能禁固于下。故遇子后
阳生之时，其气不振，阴寒反胜，则腹鸣奔响作胀，泻去一、二行乃安。此病藏于肾，宜治
下而不宜治中。方用∶
肉豆蔻 五味子各二两 吴茱萸一两 补骨脂四两 生姜八两 红枣一百枚
上捣末，以蒸熟枣肉和丸，如梧子大，每服五、七十丸，空心或食前热汤下，晚食前更
进一服。
寒泻，又名“溏泄”。其病因为脾气虚弱，加之寒气客于下部，导致水液与粪便一同趋注大肠，大便颜色多呈青黑色，治疗适宜采用温法。
春夏季节适宜使用的方剂：
川桂枝、白芍药、白术各半两，炙甘草二钱。
用水煎煮后服用。
秋冬季节适宜使用的方剂：
白芍药、白术各三钱，炮干姜半两，炙甘草二钱。
用水煎煮后服用。若病情严重，则去掉干姜，加入附子三钱。
热泻，是由于夏季热气突然侵袭太阴脾经，与湿邪相结合；其势如水倾注，因此又称“暴泻”。其症状表现为腹痛、自汗、心烦口渴、面色污垢、脉象洪数或虚大无力、肛门灼热疼痛，大便排出如热水般急迫。方剂使用：
香薷一斤，白扁豆半斤（微炒），厚朴半斤（去皮，用姜汁炙熟）。
以上药物研为细末，每次服用三钱，用水煎煮后服用。
久泻不止，是因为肠胃之间有陈旧的积滞，积滞一天不除去，腹泻就一天不会停止。治疗应当先祛除陈旧积滞，然后再进行补益。方剂使用：
厚朴、干姜、甘草、桂心、附子各二两，大黄四钱。
以上药物细细切碎，先用前五味药加水二升半，煎煮至八合，并将大黄切碎，用一碗水浸泡半天，煮取汤汁与前药汁混合，再煎煮取六合，去渣，分三次服用，一日服完。
肾泄，即五更时分发生的溏泄。其病因为肾阳虚亏，既不能温养脾土，又不能固摄于下。因此在子时之后阳气初生之时，正气不振，阴寒反而占优势，导致腹中鸣响、奔豚气作胀，腹泻一两次后才感到安宁。此病根源在肾，适宜治下焦而不适宜治中焦。方剂使用：
肉豆蔻、五味子各二两，吴茱萸一两，补骨脂四两，生姜八两，红枣一百枚。
以上药物捣碎成末，用蒸熟的枣肉调和制成丸药，大小如梧桐子，每次服用五七十丸，空腹或饭前用热汤送服，晚饭后加服一次。
Cold diarrhea, also known as "Tang Xie" (Loose Stool Diarrhea), originates from Spleen Qi deficiency and the presence of Cold pathogen in the lower jiao, causing water and feces to rush together into the Large Intestine. The stool color is often bluish-black; treatment should employ warming methods.
For Spring and Summer seasons, the following formula is suitable:
Chuan Gui Zhi (Cassiae Ramulus / Cinnamon Twig), Bai Shao Yao (Paeoniae Radix Alba / White Peony Root), and Bai Zhu (Atractylodis Macrocephalae Rhizoma) each 0.5 liang; Zhi Gan Cao (Prepared Licorice Root) 2 qian.
Decoct in water and take orally.
For Autumn and Winter seasons, the following formula is suitable:
Bai Shao Yao (White Peony Root) and Bai Zhu (Atractylodis Macrocephalae Rhizoma) each 3 qian; Pao Gan Jiang (Prepared Dried Ginger) 0.5 liang; Zhi Gan Cao (Prepared Licorice Root) 2 qian.
Decoct in water and take orally. In severe cases, remove Gan Jiang (Dried Ginger) and add Fu Zi (Aconiti Lateralis Radix Praeparata / Prepared Aconite Root) 3 qian.
Heat diarrhea occurs when summer Heat pathogen suddenly attacks the Tai Yin (Spleen) channel and combines with Dampness; its flow is like pouring water, hence it is also called "Bao Xie" (Violent/Sudden Diarrhea). Symptoms include abdominal pain, spontaneous sweating, irritability, thirst, dirty complexion, a洪 (Surging) or rapid/deficient pulse, burning pain in the anus, and stool expulsion as urgent as boiling water. The formula uses:
Xiang Ru (Moslae Herba / Chinese Motherwort) 1 jin; Bai Bian Dou (Phaseoli Semen Album / White Hyacinth Bean) 0.5 jin (lightly stir-fried); Hou Po (Magnoliae Officinalis Cortex / Magnolia Bark) 0.5 jin (peeled, stir-fried with ginger juice until cooked).
Grind the above ingredients into powder. Take 3 qian per dose, decoct in water, and take orally.
Persistent chronic diarrhea persists because there are old accumulations between the stomach and intestines. If the accumulation remains for one day, the diarrhea will not stop for one day. Treatment should first eliminate the old accumulation, followed by tonification. The formula uses:
Hou Po (Magnolia Bark), Gan Jiang (Zingiberis Rhizoma / Dried Ginger), Gan Cao (Glycyrrhizae Radix et Rhizoma / Licorice Root), Gui Xin (Cinnamomi Ramulus / Cinnamon Heart), and Fu Zi (Prepared Aconite Root) each 2 liang; Da Huang (Rhei Radix et Rhizoma / Rhubarb) 4 qian.
Finely chop the above ingredients. First, decoct the first five herbs in 2.5 sheng of water until reduced to 8 he. Meanwhile, chop Da Huang finely and soak it in one bowl of water for half a day. Boil the Da Huang to extract the liquid, combine it with the previous decoction, and further decoct to obtain 6 he. Strain the dregs, divide into three doses, and consume all within one day.
Kidney diarrhea refers to loose stool occurring at dawn (Wu Geng). Its origin lies in Kidney Yang deficiency, which fails to warm and nourish the Spleen and fails to secure the lower jiao. Therefore, after Zi hour (11 PM - 1 AM) when Yang begins to generate, the Qi is weak, and Yin-Cold prevails, causing borborygmus, distension, and a sensation of rushing gas. Relief is felt only after one or two bowel movements. This disease resides in the Kidney; treatment should focus on the lower jiao rather than the middle jiao. The formula uses:
Rou Dou Kou (Myristicae Semen / Nutmeg) and Wu Wei Zi (Schisandrae Chinensis Fructus / Schisandra Berry) each 2 liang; Wu Zhu Yu (Evodiae Fructus / Evodia Fruit) 1 liang; Bu Gu Zhi (Psoraleae Fructus / Psoralea Fruit) 4 liang; Sheng Jiang (Zingiberis Rhizoma Recens / Fresh Ginger) 8 liang; Hong Zao (Jujubae Fructus / Jujube) 100 pieces.
Crush the above ingredients into powder. Mix with the flesh of steamed Jujubes to form pills the size of Sophora seeds. Take 50-70 pills per dose, swallowing with hot water on an empty stomach or before meals. Take an additional dose before the evening meal.
