（《唐本草》）
【释名】金寄奴（大明）、乌藤菜（《纲目》）。
时珍曰∶按李延寿《南史》云∶宋高祖刘裕，小字寄奴。微时伐荻新洲，遇一大蛇，射
之。明日往，闻杵臼声。寻之，见童子数人皆青衣，于榛林中捣药。问其故。答曰∶我主为
刘寄奴所射，今合药敷之。裕曰∶神何不杀之？曰∶寄奴王者，不可杀也。裕叱之，童子皆
散，乃收药而反。每遇金疮敷之即愈。人因称此草为刘寄奴草。郑樵《通志》云∶江南人因
汉时谓刘为卯金刀，乃呼刘为金。是以又有金寄奴之名。江东人谓之乌藤菜云。
【集解】恭曰∶刘寄奴草生江南。茎似艾蒿，长三、四尺，叶似山兰草而尖长，一茎直
上有穗，叶互生，其子似稗而细。
保升曰∶今出越州，蒿之类也。高四、五尺，叶似菊，其花白色，其实黄白色作穗，夏
月收苗日干之。
颂曰∶今河中府、孟州、汉中、滁州亦有之。春生苗，茎似艾蒿，上有四棱，高二、三
尺以来。叶青似柳，四月开碎小黄白花，如瓦松，七月结实似黍而细，根淡紫色似莴苣。六
月、七月采苗及花子通用。
时珍曰∶刘寄奴一茎直上。叶似苍术，尖长糙涩，面深背淡。九月茎端分开数枝，一枝
攒簇十朵小花，白瓣黄蕊，如小菊花状。花罢有白絮，如苦 花之絮。其子细长，亦如苦
子。所云实如黍稗者，似与此不同，其叶亦非蒿类。
子（苗同）
【修治】 曰∶凡采得，去茎叶，只用实。以布拭去薄壳令净，拌酒蒸，从巳至申，曝
干用。
时珍曰∶茎、叶、花、子皆可用。
【气味】苦，温，无毒。
【主治】破血下胀。多服令人下痢（苏恭）。下血止痛，治产后余疾，止金疮血，极效

(From *Tang Bencao*)
[Names] Jinjinu (from *Daming Bencao*), Wutengcai (from *Bencao Gangmu*).
Li Shizhen states: According to Li Yanshou's *History of the Southern Dynasties*, Emperor Gaozu of Song, Liu Yu, had the childhood name Jinnu. When he was of humble status, he was cutting reeds at Xinzhou when he encountered a large snake and shot it. The next day, he returned and heard the sound of pounding medicine. Following the sound, he saw several children dressed in green robes pounding medicine in a hazel forest. He asked them the reason. They replied, "Our master was shot by Liu Jinnu; we are now preparing medicine to apply." Liu Yu said, "Why do not the spirits kill me?" They answered, "Jinnu is destined to be a king; he cannot be killed." Liu Yu scolded them, and the children scattered. He then collected the herbs and returned. Whenever he encountered metal wounds (*Jinchuang*), applying this herb led to immediate healing. People therefore called this herb Liu Jinnu Cao. Zheng Qiao stated in *Tongzhi*: People in Jiangnan referred to "Liu" as "Jin" because in Han times, the character "Liu" was decomposed into "Mao-Jin-Dao" (卯金刀). Hence, it also has the name Jinjinu. People in Jiangdong call it Wutengcai.
[Collection and Description] Su Gong says: Liu Jinnu grows in Jiangnan. The stem resembles *Artemisia argyi* (Ai Hao), three to four chi tall. The leaves resemble those of *Cymbidium* (Shanlan) but are pointed and long. A single stem rises straight with an inflorescence; leaves are alternate. The seeds resemble barnyard grass (*Bai*) but are finer.
Bao Sheng says: It is currently produced in Yuezhou and belongs to the mugwort (*Hao*) category. It is four to five chi high. Leaves resemble chrysanthemum flowers. The flowers are white, and the fruit is yellowish-white in spikes. The aerial parts are harvested in summer and dried in the sun.
Su Song says: It is also found in Hezhong Prefecture, Mengzhou, Hanzhong, and Chuzhou. Seedlings emerge in spring. The stem resembles *A. argyi*, square in cross-section, two to three chi high. Leaves are green like willow leaves. In April, it opens small yellow and white flowers resembling *Sempervivum arachnoideum* (Wasong). In July, it bears seeds resembling millet but finer. The root is pale purple, resembling lettuce. The aerial parts and flower-seeds are commonly used, harvested in June and July.
Li Shizhen says: Liu Jinnu has a single upright stem. Leaves resemble *Atractylodes lancea* (Cangzhu), pointed, long, rough, and astringent to the touch, dark green on the upper surface and lighter on the lower. In September, the stem tip branches into several twigs, each cluster bearing ten small flowers with white petals and yellow stamens, resembling small chrysanthemums. After flowering, white down appears, similar to that of *Ixeris polycephala* (Kuxing). The seeds are slender, also resembling those of *Ixeris*. The description stating the fruit resembles millet or barnyard grass seems different from this specimen, and its leaves are not of the mugwort type.
Seed (The seedling is used similarly)
[Preparation] Lei Xiao says: Upon harvesting, remove stems and leaves, using only the seeds. Wipe off the thin husks with cloth until clean. Mix with wine and steam from Si hour (09:00-11:00) to Shen hour (15:00-17:00). Then dry in the sun for use.
Li Shizhen says: Stems, leaves, flowers, and seeds are all usable.
[Favor and Toxicity] Bitter in taste, warm in nature, non-toxic.
[Indications] Breaks blood stasis and reduces distension. Excessive intake may cause diarrhea (Su Gong). Stops bleeding from the lower orifice and relieves pain; treats residual postpartum disorders; stops bleeding from metal wounds with excellent efficacy (*Bielu*). Treats heart and abdominal pain, directs Qi downward, treats water retention and blood qi stagnation, unblocks menstrual obstructions in women, and stops watery diarrhea from cholera (*Daming Bencao*). For hematuria in children, fresh material is ground into powder and taken internally (Li Shizhen).
[Attached Prescriptions] One old prescription, seven new prescriptions.
Hematochezia and Hematuria: Grind Liu Jinnu into powder. Take 2 qian mixed with tea on an empty stomach to stop bleeding immediately. (*Jijian Fang*)
Fractures and Bruises with Blood Stasis in the Abdomen: Liu Jinnu, *Drynaria fortunei* (Gusuibu), and *Corydalis yanhusuo* (Yanhusuo), each 1 liang. Decoct in 2 sheng of water until 7 he remains. Add wine and urine from a young boy, each 1 he. Warm and take in one dose. (*Qianjin Fang*)
Qi and Blood Distension: Grind the spike-seeds of Liu Jinnu into powder. Take 3 qian per dose, decocted in wine. Do not take excessively, as it may induce vomiting and diarrhea. This is a miraculous herb for breaking blood stasis. (*Weisheng Yijian Fang*)
Cholera Turning into Dysentery: Decoct Liu Jinnu herb and drink the juice. (*Shengji Zonglu*)
Scalds and Burns: Grind Liu Jinnu into powder. First, sweep the wound with rice paste and chicken feathers, then sprinkle the powder. It causes no pain and leaves no scar; it is a highly effective formula. For any scald or burn, it is advisable to first sprinkle salt powder to protect the flesh from decay, then apply the medicinal powder. (*Jingyan Fang*)
Wind Entering Wounds Causing Swelling and Pain: Grind Liu Jinnu into powder. Sprinkle on the affected area to stop pain immediately. (*Shenghui Fang*)
Nocturnal Crying in Infants: Liu Jinnu 0.5 liang, *Pheretima aspergillum* (Dilong, stir-fried) 1 fen, *Glycyrrhiza uralensis* (Gancao) 1 cun. Decoct in water and administer a small amount orally. (*Shengji Zonglu*)
Red and White Dysentery, Mixed Types, Regardless of Color: Liu Jinnu, *Prunus mume* (Wumei), and *Zingiber officinale* (Baijiang) in equal proportions. Decoct in water and take orally. For red dysentery, add more plum; for white dysentery, add more ginger. (*Ai Yuanying Ruyi Fang*)
