何首乌
味苦、涩，微温，无毒。主治瘰疬（颈部淋巴结结核），消散痈肿，治疗头面部风疮，五痔（五种痔疮），止心痛，补血气，使胡须和鬓角变黑，美容养颜。久服可强健筋骨，补益精髓，延年益寿。也可治疗妇人产后病及带下病等诸疾。本地产自顺州南河县，如今岭南、江南各州都有出产。藤蔓呈紫色，花黄白色，叶子像薯蓣但不光亮。生长时必须两株相对，根大如拳头，有赤、白两种，赤色为雄，白色为雌。又名野苗，又名交藤，又名夜合，又名地精，又名陈知白。春夏采收。临用时用苦竹刀切片，用米泔水浸泡过夜，晒干。用木臼捣碎。忌用铁器。（今附）
臣禹锡等人谨按：日华子说：味甘。久服使人有子嗣。治疗脏腑宿疾，一切冷气及肠风。此药有雌雄之分。雄者的苗叶黄白色，雌者的赤黄色。凡是配制药物必须雌雄配合使用，才有疗效。此药在《本草》中无名，因何首乌看见藤蔓夜间相交，便采集食用而见效，因此以采药人的名字命名。又名桃柳藤。
《图经》说：何首乌，本出顺州南河县，岭外、江南各州也有，如今到处都有，以西洛、嵩山及南京柘城县产的最好。春天生苗，叶子相对而生，像山药但不光泽，其茎蔓延在竹木墙壁间。夏秋开黄白花，像葛勒花。结籽有棱，像荞麦但细小，才如粟米大。秋冬挖根，大的如拳头，各有五棱瓣，像小甜瓜。这有两种：赤色为雄，白色为雌。采收时趁湿用布帛擦去泥土后，用苦竹刀切，米泔水浸泡一夜，晒干。忌铁。用木臼捣碎。一说：春采根，秋采花，九蒸九晒，才可以服用。此药本名交藤，因何首乌服用而得名。何首乌是顺州河南县人。祖父何能嗣，原名田儿，出生时阉弱，五十八岁，无妻无子。一天醉卧野外，看见田中的藤，两本异生，苗蔓相交，很久才解开，解了又合三四次。田儿心里觉得奇异，挖掘根部拿回家问乡人，无人能命名。于是晒干捣末，酒送服。七天后想行房事，一百天旧疾全愈。十年内生下几个男孩，后来改名能嗣。又给儿子庭服用，都活到一百六十岁。首乌服药，也活到一百三十岁。唐元和七年，僧人文象遇到茅山老人，于是传述此事。李翱因此写方录说：又叙述其苗像木本植物，有光泽，形状像桃柳叶，背面偏斜，单独或成对生长，不相对。有雌雄之分：雌者苗色黄白，雄者黄赤。它们生长相距较远，夜晚则苗蔓相交，有时隐藏变化不见。春末、夏中、初秋三个时节，选晴朗日子兼采雌雄。烈日晒干。研粉酒送服，很好。采收时挖尽根，趁湿润用布帛擦去泥土，不要损伤皮，密封容器储存，每月再晒一次。凡服药选偶日，二、四、六、八日是。服完，用衣覆盖出汗，导引。尤其忌猪、羊血，叙述颇详细，所以记载下来。
经验方：何首乌，新采的，去皮土后，用铜、竹刀薄切片，放入甑中如蒸饭一样，下面用瓷石锅。忌铁。旁边另烧一锅，常满添水，候药甑气上来，逐渐用热水从上淋下，不要让水满溢，直等到首乌完全没有气味，然后取下一匙头汁，白开水也可以，这是药的精华，与平常不同。治骨软风，腰膝疼，行走困难，遍身瘙痒。首乌大而花纹明显的，同牛膝锉碎各一斤，用好酒一升，浸泡七夜，晒干。在木臼内捣末蜜丸，每天空腹食前酒送服三、五十丸。又一方：治各处皮里面痛。首乌末、姜汁调成膏，痛处以帛子包裹，用火炙鞋底熨烫，妙。斗门方治瘰疬，或破或不破，以至下胸前的，都治。用九真藤取其根如鸡卵大，洗，生嚼，常服。又取叶捣碎敷在疮上，数服即止。此药久服黑发延年。或取其头获之九数的，服之成仙矣。其叶像杏，其根也像蒺藜子，用之如神。又可用来做利术，伏沙子，自有法。一名何首乌，又名赤葛。王氏博济治疥癣，满身作疮，不可治者。何首乌、艾各等分，以水煎令浓，在盆内洗之，甚能解痛，生肌肉。何首乌传昔何首乌者，顺州南河县人。祖名能嗣，父名延秀。能嗣常慕道术，随师在山。因醉夜卧山野，忽见有藤二株，相去三尺余，苗蔓相交，久而方解，解了又交。惊讶其异，至旦遂掘其根归。问诸人，无识者。后有山老忽来示之。答曰：子既无嗣，其藤乃异，此恐是神仙之药，何不服之？遂杵为末，空心酒服一钱。服数月似强健，因此常服，又加二钱。服之经年旧疾皆愈，发乌容少。数年之内，即有子，名延秀，秀生首乌，首乌之名，因此而得。生数子，年百余岁，发黑。
有李安期者，与首乌乡里亲善，窃得方服，其寿至长，遂叙其事。何首乌，味甘，生温，无毒。茯苓为使。治五痔腰膝之病，冷气心痛，积年劳瘦痰癖，风虚败劣，长筋力，益精髓，壮气驻颜，黑发延年，妇人恶血痿黄，产后诸疾，赤白带下，毒瓦斯入腹，久痢不止，其功不可具述。一名野苗，二名交藤，三名夜合，四名地精，五名首乌。本出虔州，江南诸道皆有之。苗叶有光泽，又如桃李叶，雄苗赤。根远不过三尺。春秋可采，日干。去皮为末，酒下最良。有疾即用茯苓汤下为使。常杵末，新瓷器盛，服之忌猪肉血、无鳞鱼，触药无力。此药形大如拳连珠，其中有形鸟兽山岳之状，珍也。掘得去皮，生吃，得味甘甜，休粮。赞曰：神效助道，着在仙书。雌雄相交，夜合昼疏。服之去谷，日居月诸。返老还少，变安病躯。有缘者遇，传之勿泄，最尔自如。明州刺史李远传录经验：何首乌所出顺州南河县、韶州、潮州、恩州、贺州、广州四会县、潘州，以上出处为上。邕州晋兴县、桂州、康州、春州、勒州、高州、循州，以上所出次之。其仙草五十年者如拳大，号山奴，服之一年，髭鬓青黑；一百年如碗大，号山哥，服之一年，颜色红悦；一百五十年如盆大，号山伯，服之一年，齿落重生；二百年如斗栲栳大，号山翁，服之一年，颜如童子，行及奔马；三百年如三斗栲栳大，号山精，服之一年延龄，纯阳之体，久服成地仙。

Added during the Jiyou year from *Yan Yi*:
Polygonum multiflorum (He Shou Wu)
Bitter and astringent in taste, slightly warm in nature, non-toxic. Primarily treats scrofula (tuberculous lymphadenitis of the neck), dissipates carbuncles and swellings, treats wind sores on the head and face, five types of hemorrhoids (Wu Zhi), stops heart pain, nourishes blood and qi, darkens beard and sideburns, and beautifies complexion. Long-term use strengthens sinews and bones, benefits essence and marrow, and prolongs life. It also treats various diseases in women after childbirth and leukorrhea. Originally produced in Nanhe County, Shunzhou; now found in Lingnan and various prefectures in Jiangnan. The vine is purple, flowers are yellowish-white, leaves resemble *Dioscorea* (Shan Yao) but lack luster. They must grow in pairs; roots are fist-sized, with red and white varieties: red is male, white is female. Also known as Ye Miao, Jiao Teng, Ye He, Di Jing, and Chen Zhi Bai. Harvested in spring and summer. Before use, slice with a bitter bamboo knife, soak in rice wash water overnight, dry in the sun, and pound in a wooden mortar. Avoid ironware. (Currently attached)
Minister Yuxi et al. note according to Ri Hua Zi: Sweet in taste. Long-term use enables procreation. Treats chronic internal organ diseases, all forms of cold qi, and intestinal wind. This herb has male and female distinctions. Male plants have yellowish-white leaves; female plants have reddish-yellow leaves. For medicinal preparation, male and female parts must be combined for efficacy. This herb was unnamed in the *Ben Cao*, named after He Shou Wu who saw the vines intertwining at night, harvested and consumed it with effect, thus naming it after himself. Also known as Tao Liu Teng.
*Tu Jing* states: Polygonum multiflorum (He Shou Wu) originally came from Nanhe County, Shunzhou, and is also found in Lingnan and Jiangnan prefectures; currently available everywhere, with the best quality from Xiluo, Songshan, and Zhoucheng County, Nanjing. Sprouts emerge in spring, leaves grow opposite each other, resembling sweet potato (*Dioscorea*) but without luster; stems creep among bamboo, wood, and walls. Yellowish-white flowers bloom in summer and autumn, resembling *Pueraria* (Ge Gen) flowers. Seeds are angular, smaller than buckwheat, only the size of millet grains. Roots are dug in autumn and winter, fist-sized, with five ridges, resembling small melons. There are two types: red is male, white is female. When harvesting, wipe off soil with cloth while moist, slice with a bitter bamboo knife, soak in rice wash water overnight, and dry. Avoid iron. Pound in a wooden mortar. One method says: harvest roots in spring, flowers in autumn, steam nine times and dry nine times before consumption. This herb was originally named Jiao Teng, named after He Shou Wu's consumption. He Shou Wu was a native of Nanhe County, Shunzhou. His grandfather, Neng Si, originally named Tian Er, was weak since birth, fifty-eight years old, without wife or children. One day, drunk and sleeping in the wild, he saw vines growing separately but intertwining, separating and re-intertwining three or four times. Tian Er found this strange, dug up the root, and asked villagers, but no one knew its name. He dried it, pounded it into powder, and took it with wine. After seven days, he desired sexual intercourse; after one hundred days, his old ailments were cured. Ten years later, he fathered several sons, and later changed his name to Neng Si. He gave it to his son Ting, who lived to 160 years. Shou Wu took the medicine and lived to 130 years. In the seventh year of Yuanhe in the Tang Dynasty, Monk Wenxiang met an old man from Maoshan and transmitted this story. Li Ao wrote in *Fang Lu*: He also described the shoots as woody, glossy, shaped like peach or willow leaves, asymmetrical, growing singly or in pairs but not opposite. With male and female distinctions: female shoots are yellowish-white, male shoots are yellow-red. They grow far apart but intertwine at night, sometimes disappearing. Harvest both sexes on sunny days in late spring, mid-summer, and early autumn. Dry under intense sun. Powder taken with wine is excellent. Dig up all roots, wipe clean with cloth while moist, do not damage the skin, store in sealed containers, and dry again monthly. Take medicine on even days (2nd, 4th, 6th, 8th). After taking, cover with clothes to induce sweating and practice Daoyin (guiding and pulling exercises). Especially avoid pig and sheep blood. The description is detailed, hence recorded.
Empirical Formula: Freshly harvested Polygonum multiflorum (He Shou Wu), peel and remove soil, slice thinly with copper or bamboo knives, place in a steamer over a porcelain stone pot. Avoid iron. Boil another pot nearby, keep full of water. When steam rises from the herb steamer, pour hot water from above continuously, ensuring it does not overflow, until the herb loses all odor. Collect one spoonful of the liquid; plain water is also acceptable. This is the essence of the medicine, distinct from ordinary preparations. Treats bone-softening wind (osteomalacia/rheumatism), waist and knee pain, difficulty walking, and generalized pruritus. Take large Polygonum multiflorum (He Shou Wu) with distinct patterns and Achyranthes bidentata (Niu Xi), chopped, one jin each. Soak in one sheng of good wine for seven nights, dry, pound into powder in a wooden mortar, make honey pills. Take 30-50 pills with wine before meals on an empty stomach daily. Another formula: Treats deep tissue pain. Mix Polygonum multiflorum (He Shou Wu) powder with ginger juice to form a paste, wrap the painful area with cloth, and iron with a heated shoe sole. Excellent. Doumen Fang treats scrofula (Luo Li), whether ulcerated or not, extending to the lower chest. Use Nine-True Vine (Jiu Zhen Teng), take roots egg-sized, wash, chew raw, take regularly. Also take leaves, pound, and apply to sores; stops after a few applications. Long-term use darkens hair and prolongs life. Or take nine heads, consume to become immortal. Leaves resemble apricot, roots resemble Tribulus (Ci Ji Li), use as if divine. Can also be used for alchemical arts, subduing sand, with specific methods. Also known as He Shou Wu, Chi Ge. Wang Shi Bo Ji treats tinea and eczema, widespread sores, incurable cases. Equal parts Polygonum multiflorum (He Shou Wu) and Artemisia argyi (Ai Ye), boil in water until concentrated, wash in a basin. Relieves pain significantly, generates flesh. Legend of He Shou Wu: He Shou Wu was from Nanhe County, Shunzhou. Grandfather Neng Si, father Yan Xiu. Neng Si admired Daoist arts, followed a master in the mountains. Drunk and sleeping in the wild, he saw two vines, three chi apart, intertwining, separating, and re-intertwining. Surprised, he dug the roots at dawn. Asked others, no one recognized them. A mountain elder appeared and showed him. Answered: You have no heir, this vine is strange, likely an immortal medicine, why not take it? Pounded into powder, taken with wine on an empty stomach, one qian. After months seemed robust, continued taking, increased to two qian. After a year, old ailments cured, hair blackened, appearance rejuvenated. Within years, had a son, named Yan Xiu. Yan Xiu had Shou Wu, hence the name. Fathered several sons, lived over 100 years, hair black.
Li Anqi, a relative and friend of Shou Wu, stole the formula and took it, living a long life, thus narrating the event. Polygonum multiflorum (He Shou Wu), sweet in taste, warm in nature, non-toxic. Poria cocos (Fu Ling) serves as an assistant. Treats five types of hemorrhoids, waist and knee diseases, cold qi, heart pain, chronic emaciation with phlegm stagnation, wind deficiency and deterioration, strengthens sinews, benefits essence and marrow, boosts qi, preserves youth, darkens hair, prolongs life, treats bad blood and sallow complexion in women, postpartum diseases, red and white leukorrhea, toxic vapors entering the abdomen, chronic dysentery. Its merits cannot be fully listed. Also known as Ye Miao, Jiao Teng, Ye He, Di Jing, and Shou Wu. Originally from Qianzhou, found throughout Jiangnan regions. Shoots and leaves are glossy, like peach and plum leaves, male shoots are red. Roots do not exceed three chi. Harvested in spring and autumn, dried in sun. Peel, powder, taken with wine is best. If diseased, take with Poria cocos (Fu Ling) decoction as assistant. Usually pound into powder, store in new porcelain, avoid pork blood and scaleless fish upon ingestion, as they reduce efficacy. This herb is fist-sized, bead-like, containing shapes resembling birds, beasts, and mountains; precious. Dig, peel, eat raw, tastes sweet, aids fasting. Eulogy: Divine efficacy assists the Dao, recorded in immortal books. Male and female intertwine, join at night, separate by day. Consume to eliminate grain, dwell day and night. Return to youth, transform sick body into peace. Meet those with destiny, transmit without leaking, most natural. Governor Li Yuan of Mingzhou transcribed empirical experience: Origins from Nanhe County, Shunzhou; Shaozhou; Chaozhou; Enzhou; Hezhou; Sihui County, Guangzhou; Panzhou. These origins are superior. Jinxiang County, Yongzhou; Guizhou; Kangzhou; Chunzhou; Lezhou; Gaozhou; Xunzhou. These origins are secondary. Immortal herbs aged 50 years are fist-sized, called Shan Nu, take one year, beard and sideburns turn black; 100 years bowl-sized, called Shan Ge, take one year, complexion rosy and joyful; 150 years basin-sized, called Shan Bo, take one year, lost teeth regrow; 200 years bucket-sized, called Shan Weng, take one year, face like a child, walk as fast as a galloping horse; 300 years three-bucket sized, called Shan Jing, take one year, extend lifespan, pure yang body, long-term use becomes an earth immortal.
*Yan Yi* states: Polygonum multiflorum (He Shou Wu) darkens beard and sideburns; antagonistic with radish, causing premature graying; commonly used to treat intestinal wind heat.
