味苦、甘、酸，性微寒，无毒。主治妇女乳痈（乳房肿痛），七伤（泛指多种虚损劳伤），带下病（阴道分泌物异常），止痛，去除恶肉（坏死的腐肉），止汗，治疗金疮（金属利器造成的创伤），止脓血，治疗各种恶疮、热疮，消酒毒，消除消渴（口渴多饮的症状），补益绝伤（严重的跌打损伤或断裂伤），治疗产后内塞（产后瘀血阻滞），可制作成金疮膏。生长在桐柏山及冤句县的山谷中。二月和八月采集根部，晒干。（与头发同用效果良好，忌与麦门冬同用。）
陶隐居说：现在附近各地都有生长，叶子像榆树但更长，刚长出来时贴地铺展，花和果实紫黑色像豆豉，所以名叫玉豉。一根茎笔直向上生长，根部也可以用来酿酒。道家方术中将它烧成灰，能腐蚀石头。缺乏茶叶时用它的叶子做饮料也很好。现在我参考其他版本的注释说：现在的人只用于治疗冷痢和热痢以及小儿疳积痢疾，如果是热极的情况，效果显著。臣禹锡等人谨慎按照《药性论》说：地榆，味苦，性平。能治疗产后残留的瘀血，疹痛，七伤，治疗金疮，止血痢，蚀除脓液。萧炳说：现在的方剂中用它配合樗皮共同治疗赤白痢。日华子说：排脓，止吐血，止鼻出血，止月经不止，止血崩，治疗产前产后各种血证，赤白痢疾并水样腹泻，浓煎可以止肠风（便血）。只要是平原沼泽地带都有，独茎，花紫色，七月、八月采集。
《图经本草》说：地榆，生长在桐柏及冤句山谷，现在到处都有。宿根，三月内生苗，刚长出来时贴地铺展，茎直立，高三四尺，对生分出叶子。叶子像榆树但稍窄，细长呈锯齿状，青色。七月开花像桑葚，紫黑色。根外部黑内部红，像柳根。二月、八月采集，晒干。叶子不用，山民在缺乏茶叶时，采集这种叶子做饮料也很好。古断下方：鼠尾草各三两，水二升，煮至一半，一次性服用。如果不断根，用水浸泡屋尘，喝一小杯投入其中。不过多次制作，才能痊愈。小儿疳痢，也单煮汁液像饴糖一样给患儿服用，病就好了。又捣碎新根取汁饮用，兼以浸渍疮口，很好。崔元亮《海上方》：治疗赤白痢疾导致身体消瘦如骨立者，用地榆一斤，水三升，煮取一升半，去渣再煎成稠糖浆状，过滤，空腹服三合，每天两次。
《唐本注》说：主治带下十二种病。《孔氏音义》说：一是多赤色，二是多白色，三是月经不通，四是阴部溃烂，五是子宫坚硬，六是子门偏斜，七是性交时疼痛，八是小腹寒冷疼痛，九是子门闭塞，十是子宫寒冷，十一是梦与鬼交，十二是五脏功能不定。用叶子做饮料代替茶，很能清热。《圣惠方》：治疗妇人漏下赤白不止，使人黄瘦虚竭。用地榆三两细切，米醋一升，煮十余沸，去渣。饭前稍热服一合，也能治吐血。《千金翼方》：治疗手指被切断后的逆肿。单煮地榆作汤浸渍患处，半天痊愈。《肘后方》：治疗虎、犬咬人。用地榆根末，服方寸匕，每天一至二次，敷在疮上尤其好。葛氏：毒蛇咬人。捣碎地榆根，绞取汁饮用，兼以浸渍疮口。梅师方：治疗狗咬人。煮地榆饮用，兼将粉末敷在疮上，服方寸匕，每天三次，忌酒。如果治疗疮口已经愈合者。捣生韭菜汁，饮用一二升。《齐民要术》：地榆汁酿酒。治疗风痹，补脑。《三洞要录》：地榆草锉一升，稻米一升，白玉屑一升，三物取白露汁二升，放在铜器中煮米熟，绞取汁。玉屑化为水，名叫玉液。用药醴制中，所谓神玉浆。
Di Yu (Sanguisorbae Radix)
Taste: Bitter, sweet, sour. Nature: Slightly cold. Toxicity: Non-toxic. Indications: Primarily treats breast abscess (Ru Yong), Qi Shang (seven types of injuries/deficiencies), leukorrhea, pain relief, removal of necrotic tissue, sweating cessation, treatment of metallic weapon wounds (Jin Chuang), stopping pus and blood discharge, treating various malignant sores and heat sores, resolving alcohol toxicity, eliminating Xiao Ke (wasting-thirst syndrome), tonifying severe trauma (Jue Shang), treating postpartum internal obstruction, and can be prepared as a plaster for metallic weapon wounds. Grows in the valleys of Tongbai Mountain and Yuanju County. Roots are harvested in February and August and dried in the sun. (Works well with human hair; incompatible with Ophiopogonis Radix.)
Tao Hongjing states: It is now found everywhere near the capital. The leaves resemble those of elm but are longer; when first sprouting, they spread along the ground. The flowers and seeds are purple-black like fermented soybeans (Chi), hence the name Yu Chi (Jade Bean). A single stem grows straight upward, and the root can also be used to brew wine. In Daoist methods, it is burned into ash, which can corrode stones. When tea is scarce, its leaves make a good beverage. I have checked other editions' notes stating: Currently, people use it only for treating cold dysentery, heat dysentery, and children's malnutrition dysentery (Gan Li); if the heat is extreme, it is effective.
Chen Yuxi et al., according to *Yao Xing Lun* (Treatise on the Properties of Medicinals), state: Di Yu tastes bitter and is neutral in nature. It can treat residual blood stasis after childbirth, rash pain, Qi Shang, metallic weapon wounds, stop bloody dysentery, and erode pus. Xiao Bing states: Current prescriptions use it together with Pterocarpus bark (Chu Pi) to treat red and white dysentery. Ri Huazi states: It expels pus, stops hematemesis (vomiting blood), epistaxis (nosebleed), menorrhagia, metrorrhagia, and various bleeding disorders before and after childbirth; red and white dysentery and watery diarrhea; decocted strongly, it stops intestinal wind (blood in stool). It grows in plains and marshes, has a single stem, purple flowers, and is harvested in July and August.
*Tujing* states: Di Yu grows in the valleys of Tongbai and Yuanju, and is now found everywhere. It has perennial roots; seedlings emerge in March, spreading along the ground initially. The stem is straight, three to four chi high, with opposite leaves. The leaves resemble elm leaves but are slightly narrower, long, thin, serrated, and green. Flowers appear in July, resembling mulberries, purple-black. The root is black outside and red inside, resembling willow roots. Harvested in February and August, dried. The leaves are usually not used, but mountain dwellers collect them as a tea substitute when tea is unavailable.
Ancient Duanshou Formula: Rat-tail sage (Shu Wei Cao) 3 liang each, water 2 sheng, boil until half remains, take at once. If the condition persists, soak house dust in water, drink a small cup, and apply. Repeat preparation if necessary until cured. For children's Gan Li, boil alone until syrup-like consistency and administer; the disease resolves. Alternatively, crush fresh roots, extract juice, drink, and apply to sores; this is excellent. Cui Yuanliang's *Haishang Fang*: For red and white dysentery causing emaciation, use Di Yu 1 jin, water 3 sheng, boil to 1.5 sheng, remove dregs, re-boil to thick syrup consistency, filter, take 3 he empty-stomach, twice daily.
*Tang Ben Zhu* states: Treats twelve types of leukorrhea. *Kong Shi Yin Yi* states: 1. Excessive red discharge; 2. Excessive white discharge; 3. Amenorrhea; 4. Genital ulceration; 5. Hard uterus; 6. Deviated cervical os; 7. Pain during intercourse; 8. Cold pain in lower abdomen; 9. Closed cervical os; 10. Cold uterus; 11. Nocturnal emission/dreams of sexual intercourse with spirits; 12. Unstable five zang organs. Using leaves as tea substitute effectively clears heat. *Shenghui Fang*: Treats persistent red and white vaginal discharge causing sallow complexion, emaciation, and deficiency exhaustion. Use Di Yu 3 liang finely chopped, rice vinegar 1 sheng, boil ten times, remove dregs. Take 1 he warm before meals; also treats hematemesis. *Qianjin Yifang*: Treats swelling from severed fingers. Boil Di Yu alone as a decoction to soak the area; heals in half a day. *Zhouhou Fang*: Treats tiger or dog bites. Administer Di Yu root powder, 1 cun bi per dose, one to two times daily; applying to the wound is especially good. Ge Shi: Treats venomous snake bites. Crush Di Yu root, extract juice, drink, and apply to sores. Mei Shi Fang: Treats dog bites. Boil Di Yu to drink, apply powder to sores, take 1 cun bi, three times daily; avoid alcohol. If treating healed sores, crush raw Chinese chive, extract juice, drink 1-2 sheng. *Qimin Yaoshu*: Brew wine with Di Yu juice. Treats wind-bi (painful obstruction syndrome), tonifies the brain. *Sandong Yaolu*: Di Yu grass 1 sheng, glutinous rice 1 sheng, white jade particles 1 sheng. Take dew collected on the White Dew solar term, 2 sheng. Place in a copper vessel, cook rice until done, strain juice. Jade particles dissolve into water, named Yu Ye (Jade Liquid). Mix with medicinal wine, known as Shen Yu Jiang (Divine Jade Elixir).
*Yanyi* states: Di Yu has a sinking and cold nature. Enters the Lower Jiao. It can be used for heat-blood dysentery. However, for patients with deficiency-cold or watery white dysentery, it should not be used lightly.
