地榆药性寒凉且趋向下行，凡是因虚寒导致的腹泻，或因气虚下陷引起的崩漏和带下病，均依法禁用。
【槐实/槐角】
味苦、酸，性寒，无毒。归入肝、大肠二经。含有花蕊且陈久的药材为佳。微炒后使用。
能止大便出血，消除血痢，很大程度上依赖其清肠的功效。治疗五种痔疮，明目，都借助于其涤除热邪的作用。将其炒香后频繁咀嚼，能治疗失音症。
槐子：名为槐角，用法大致相同，兼有行血和降气的作用，也能促进分娩但会导致堕胎。
槐树感应天地阴寒之气，兼具木与水的化生特性，因此是凉血的要药。血液不热则阴液自然充足，眼疾与痔证便可同时痊愈。

（此条见食疗部分）
【石榴皮】
味酸、涩，性温，无毒。归入脾、肺、肾三经。
适用于久泻久痢导致肠道虚弱，以及崩漏带下过多即将脱垂的情况。水煎服用可驱除蛔虫。汁液点眼可止泪。
石榴味酸涩，因此常用于治疗下元不固、崩中漏下的方剂中。如果服用过早，反而会造成危害。
【乌梅】
味苦，性温，无毒。归入脾、胃二经。
止泻痢效果奇特，固摄精液颇为有效。
新发的痢疾，若湿热严重者忌服。
【椿皮】
俗称臭椿。味苦涩，性寒，有小毒。向东生长的根部品质较好，需用醋炙制。
能收敛止血、止泻痢、杀虫并收缩松弛的肠道。
因其苦寒的性质，虚寒者禁用，肾中真阴亏损者也应忌用，因为其药性过于燥烈。仅用于丸药制作，不用于汤剂煎煮。

[Di Yu - Sanguisorbae Radix]
Bitter in taste, cold in nature, non-toxic. Enters the Liver and Large Intestine meridians. Adverse to Ophiopogonis Radix (Maidong).
Stops bleeding and treats intestinal wind hemorrhoids; eliminates leukorrhea and the "five leaks" syndromes.
Its taste is bitter and strong; its nature is heavy and descending. It excels in treating blood disorders of the Lower Jiao and simultaneously clears damp-heat.
Sanguisorbae Radix is cold and directs downwards. For diarrhea caused by deficiency-cold, or for metrorrhagia and leukorrhea due to Qi sinking, it is contraindicated according to standard protocols.
[Huai Jiao - Sophorae Fructus]
Bitter and sour in taste, cold in nature, non-toxic. Enters the Liver and Large Intestine meridians. Those containing stamens and aged are superior. Lightly stir-fry before use.
Stops hematochezia and eliminates bloody dysentery, relying significantly on its ability to clear the intestines. Treats the five types of hemorrhoids and brightens the eyes, all benefiting from its heat-purging efficacy. Chew frequently after stir-frying until fragrant to treat aphonia.
The seed: Named Huai Jiao, with similar usage. It promotes blood circulation and descends Qi; it can also induce labor but causes abortion.
Having absorbed the Yin-cold Qi of heaven and earth, and possessing the transformations of Wood and Water, it is a crucial herb for cooling blood. When blood is not hot, Yin naturally suffices, thereby curing both eye diseases and hemorrhoidal conditions.
Note: Sophora is purely Yin in nature. It is contraindicated for those with deficiency-cold, and even for those with deficiency-heat rather than excess-fire.
[Huang Lian - Coptidis Rhizoma]

For epistaxis or nasal congestion, grind into powder and pack into the nostrils.
When stir-frying, scald with talcum powder. Combined with Picrorhizae Rhizoma (Huhuanglian), processed Pangolin Scales (Paoshanjia), and Sophorae Flos (Huaimi), named Hulian Zhuidu Wan, it is highly effective for treating hemorrhoids and fistulas.

[Shi Liu Pi - Punicae Pericarpium]

Indicated for chronic diarrhea and dysentery leading to intestinal emptiness, and for excessive metrorrhagia and leukorrhea approaching collapse. Decoct in water to expel roundworms. Apply juice to the eyes to stop tearing.

Commonly known as Chou Chun (Stinky Toon). Bitter and astringent in taste, cold in nature, slightly toxic. The root growing towards the east is superior; process with vinegar.
Astringes blood, stops diarrhea and dysentery, kills parasites, and retracts prolapsed intestines.
Due to its bitter-cold nature, it is contraindicated for deficiency-cold constitutions and those with depletion of True Yin in the Kidneys, as it is merely drying. It is used only in pill forms, not in decoctions.
Chun Bai Pi (Toon Bark): Refers to Xiang Chun bark. Its main uses are similar, but its efficacy is slightly weaker.
