It is stated that diarrhea and dysentery originating from the zang-fu organs present various symptoms. Generally, they are analyzed in terms of wind, dampness, and heat, indicating that cold patterns are rare while heat patterns are common. Cold patterns do not persist; thus, it is said that acute diarrhea does not belong to Yin, and chronic diarrhea does not belong to Yang. Medical theories state: In spring, one should keep the body relaxed; relaxation allows the Liver Wood Qi to flourish. Conversely, remaining still and closed mimics the autumnal phase, where Metal controls Wood, causing Wind Qi to be stored internally. By the Summer Solstice, Fire Qi is abundant and Metal Qi recedes, leaving only excessive Fire and Wood Qi, which damages Spleen Earth. Mild cases manifest as *sun-xie* (diarrhea with undigested food), fever, a洪 (surging) pulse, and inability to digest food; severe cases manifest as dysentery with thick, sticky pus and blood, tenesmus (urgent need to defecate with heavy sensation in the rectum). Therefore, all diarrheal discharges containing thick, sticky substances are attributed to Fire. The Classics state: When urination is painful accompanied by pus and blood in stool, it indicates that Qi movement stops bleeding. One should use Dahuang Tang (Rhubarb Decoction) for purgation, which is a heavy formula; Huangqin Shaoyao Tang (Scutellaria and Peony Decoction) is a light formula. This follows the principle of "draining the son when excess," allowing Liver Wood to become deficient thereby strengthening Spleen Earth. Thus, the Classics say: Injury by Wind in Spring leads to *sun-xie* in Summer; this violates the Qi of the four seasons and is self-inflicted. Some suffer from dampness invading the Taiyin Spleen Meridian, resulting in watery, loose stools, heaviness of the body, slight fullness, and loss of taste for grains. If appropriate in Spring to tonify with Yihuang San (Benefit Yellow Powder), in Summer one should drain. Medical methods state: Tonification, draining, harmonization, and astringency are indicated. Harmonization uses Shaoyao Tang (Peony Decoction); astringency uses Hezi Tang (Persimmon Seed Decoction). Chronic cases risk progressing to pus and blood dysentery; this is transmission from Spleen Meridian to Kidney, termed "Thief Evil" (Zei Xie), making it difficult to cure. If diarrhea precedes slippage/incontinence, it is termed "Minor Evil" and is easy to recover from. These are all due to Spleen Earth being affected by dampness, an action of Heaven, which even sages cannot escape. Mouth tastes flavors, nose inhales Qi; these enter via the nose, accumulate in the Spleen, and cause watery diarrhea. Disorder of the Jueyin Meridian causes persistent dysentery with a deep, slow pulse, cold extremities, and thick, sticky pus and blood; this is difficult to treat. Ma Huang Tang (Ephedra Decoction) and Xiao Xuming Tang (Minor Continuation of Life Decoction) should be used to induce sweating. Medical methods state: When exterior pathogens retreat inward, dispersing the exterior pathogens leads to self-healing. Sudden silent diarrhea, cold body, spontaneous sweating, clear urine, fecal incontinence, weak breathing, micro-pulse, and vomiting require urgent warming with heavy medicines; Jiangshui San (Fermented Grain Water Powder) is such a formula. Thus, medical methods state: Tenesmus requires purgation; abdominal pain requires harmonization; body heaviness requires removal of dampness; wiry pulse requires dispelling wind; thick, sticky pus and blood require exhausting pathogens with heavy medicines; cold body with spontaneous sweating requires warming with toxic medicines; internal contraction of Wind pathogens requires sweating for recovery; loose stools constituting dysentery require warming. Furthermore: Exterior conditions are dispersed; interior conditions are purged; upper conditions are vomited; lower conditions are exhausted. Surface heat is internally drained; urinary obstruction is separated and promoted. Also: Excess is harmonized; deficiency is supported; excessiveness is stopped. Military strategy states: Avoid the enemy's sharp onset, strike their fatigue and return; this applies to treating diarrhea. (Above excerpted from *Huofa Jiyao*)
[Shaoyao Huangqin Tang] Treats diarrhea/dysentery with abdominal pain, tenesmus, fever, chronic non-resolution, surging/rapid pulse, and dysentery with thick, sticky pus and blood.
Huangqin (Scutellariae Radix), Shaoyao (Paeoniae Radix Alba) (each 1 liang), Gancao (Glycyrrhizae Radix et Rhizoma) (0.5 liang).
Crush the herbs. Take 0.5 liang per dose, add 1.5 cups of water, decoct to 1 cup, remove dregs, and take warm. No fixed time.
[Dahuang Tang] Treats chronic diarrhea/dysentery with thick, sticky pus and blood, tenesmus, and uncontrolled frequency day and night.
Dahuang (Rhei Radix et Rhizoma) (1 liang).
Crush the single herb, soak in 2 large cups of good wine for half a day, then decoct together until half remains. Remove dregs, divide the liquid into two doses, and take at once. Stop if dysentery ceases; if not, repeat. Take until purgation occurs. Afterwards, administer Shaoyao Tang to harmonize. Once dysentery stops, administer Baizhu Huangqin Tang to thoroughly eliminate toxicity.
[Shaoyao Tang] Moves Blood and regulates Qi. The Classics state: Painful urination with pus/blood in stool indicates Qi movement stops bleeding. Moving Blood heals the bowel; regulating Qi eliminates tenesmus.
Shaoyao (Paeoniae Radix Alba) (1 liang), Danggui (Angelicae Sinensis Radix), Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix) (each 0.5 liang), Dahuang (Rhei Radix et Rhizoma) (3 qian), Guizhi (Cinnamomi Ramulus) (2.5 qian), Gancao (Glycyrrhizae Radix et Rhizoma) (stir-baked), Binglang (Arecae Semen) (each 2 qian), Muxiang (Aucklandiae Radix) (1 qian).
Crush the nine herbs. Take 5 qian per dose, add 2 cups of water, decoct to 1 cup, remove dregs, and take warm. If dysentery persists, gradually increase Dahuang. Take after meals. ○ For post-defecation intestinal toxin, add Huangbai (Phellodendri Cortex) 0.5 liang.
[Baizhu Huangqin Tang] After previous medicines clear dysentery, further harmonization is needed.
Baizhu (Atractylodis Macrocephalae Rhizoma) (1 liang), Huangqin (Scutellariae Radix) (7 qian), Gancao (Glycyrrhizae Radix et Rhizoma) (3 qian).
Crush the three herbs, divide into three doses. Add 1.5 cups of water, decoct to 1 cup, and take warm.
[Jiangshui San] Treats sudden watery diarrhea, generalized spontaneous sweating, whole-body coldness, micro/weak pulse, scarcity of Qi unable to speak, and severe vomiting. This is an acute condition.
Banxia (Pinelliae Rhizoma) (2 liang, prepared separately), Fuzi (Aconiti Lateralis Radix Praeparata), Guizhi (Cinnamomi Ramulus), Ganjiang (Zingiberis Rhizoma) (prepared), Gancao (Glycyrrhizae Radix et Rhizoma) (honey-roasted, each 5 qian), Liangjiang (Alpiniae Officinarum Rhizoma) (2.5 qian).
Grind the six herbs into powder. Take 3-5 qian per dose, add 2 cups of fermented grain water (Jiangshui), decoct to 1 cup, and take hot with dregs. Severe cases: 3-4 doses; mild cases: 1-2 doses. Taiyang Meridian injury transmitting to Taiyin causes dysentery with loose stools; Da Chang (Large Intestine) fails to consolidate, leading to sudden defecation of oily, shiny stool, possibly with hard particles. Urging without completion, copious clear urine indicates Cold; warming is indicated. Spring/Summer: Guizhi Tang (Cinnamon Twig Decoction); Autumn/Winter: Baizhu Tang (Atractylodes Decoction).
[Guizhi Tang]
Guizhi (Cinnamomi Ramulus), Baizhu (Atractylodis Macrocephalae Rhizoma), Shaoyao (Paeoniae Radix Alba) (each 5 qian), Gancao (Glycyrrhizae Radix et Rhizoma) (honey-roasted, 2 qian).
Crush the four herbs. Take 5 qian per dose, add 1 cup of water, decoct to 0.7 cup, remove dregs, and take warm.
[Baizhu Tang]
Baizhu (Atractylodis Macrocephalae Rhizoma), Shaoyao (Paeoniae Radix Alba) (each 3 qian), Ganjiang (Zingiberis Rhizoma) (5 qian, prepared), Gancao (Glycyrrhizae Radix et Rhizoma) (honey-roasted, 2 qian).
Make into coarse powder. Decoct as above. For severe cases, remove Ganjiang and add Fuzi (Aconiti Lateralis Radix Praeparata) 3 qian, because pungent flavors can disperse.
