治疗肠癖下血呈喷射状，血液喷出有力且射程远，四散如筛孔般分布，多在春二月间下行发作，腹部剧烈疼痛，这是阳明经气冲盛、热毒所致。应当去除湿毒，调和血液即可痊愈。
生地、牡丹皮、生甘草（各五分）、熟甘草、黄芩（各一钱）、归身、熟地、苍术、秦艽、肉桂（各三分）、陈皮、升麻（各七分）、白芍（一钱半）。以上作为一剂，加水四钟，煎煮至二钟，分两次服用。

治疗因饮食不节制、起居无规律，导致阴经受邪。阴经受邪则病入五脏，五脏充满闭塞，向下表现为完谷不化的泄泻，日久发展为肠癖，水谷与血液分开呈喷射状排出。此时正值夏季，湿热之气过盛，正是客气（外感邪气）强盛而主气（当令之气）虚弱的时候。所以肠癖的症状严重，以此方主治。
熟地、当归、青皮、槐花（炒制，各五分）、知母（去毛，炒制）、黄柏（炒制，各一钱）。以上作为一剂，用水煎服。如果小便涩痛，脐下闷胀，或者大便后有重坠感，调入木香、槟榔末（各五分），空腹服用。

If abdominal pain is severe, mix with Muxiang (Aucklandiae Radix) powder and take.
Treats hematochezia without abdominal pain, which is termed "Damp-Toxin Lower Bleeding" (Shi Du Xia Xue).
Huanglian (Coptidis Rhizoma), Danggui (Angelicae Sinensis Radix) (each 5 qian), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, 1.5 qian). Decoct in water and take on an empty stomach.

Treats Changpi with lower bleeding presenting as a jet stream; the blood spurts out with force and shoots far, scattering like a sieve. This often occurs downward in the second month of spring, with severe abdominal pain. This is caused by Qi rushing in the Yangming channel and Heat-Toxin. One should eliminate Damp-Toxin and harmonize the Blood to achieve recovery.
Shengdi (Rehmanniae Radix), Mudanpi (Moutan Cortex), Sheng Gancao (Glycyrrhizae Radix et Rhizoma, raw) (each 5 fen), Shu Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried), Huangqin (Scutellariae Radix) (each 1 qian), Guishen (Radix Angelicae Sinensis), Shudi (Rehmanniae Radix Preparata), Cangzhu (Atractylodis Rhizoma), Qinjiao (Gentianae Macrophyllae Radix), Rougui (Cinnamomi Cortex) (each 3 fen), Chenpi (Citri Reticulatae Pericarpium), Shengma (Cimicifugae Rhizoma) (each 7 fen), Baishao (Paeoniae Radix Alba) (1.5 qian).

Another prescription: Add Baizhu (Atractylodis Macrocephalae Rhizoma) and Diyü (Sanguisorbae Radix).
Treats conditions where improper diet and irregular daily life cause Yin channels to be affected. When Yin is affected, pathogens enter the Five Zang organs. If they fill and obstruct the Zang organs, it manifests downward as Sundxie (undigested food in stool); prolonged, it becomes Changpi, where water, grain, and blood are expelled separately in a jetting manner. At this time, summer arrives with excessive Damp-Heat, when pathogenic Qi (Ke Qi) is strong and host Qi (Zhu Qi) is weak. Thus, the symptoms of Changpi are severe, and this formula governs them.
