（《本经》上品）
【释名】云华、云珠、云英、云液、云砂、磷石（《本经》）。
时珍曰∶云母以五色立名，详见下文。按《荆南志》云∶华容方台山出云母，土人候云
所出之处，于下掘取，无不大获，有长五、六尺可为屏风者，但掘时忌作声也。据此，则此
石乃云之根，故得云母之名，而云母之根，则阳起石也。《抱朴子》有云∶服云母十年，云
气常覆其上。服其母以致其子，理自然也。
【集解】《别录》曰∶云母生泰山山谷、齐山、庐山及琅琊北定山石间，二月采之。云
华，五色具；云英，色多青；云珠，色多赤；云液，色多白；云砂，色青黄；磷石，色正白。
弘景曰∶按∶《仙经》云母有八种∶向日视之，色青白多黑者，名云母；色黄白多青者
，名云英；色青黄多赤者，名云珠；如冰露乍黄乍白者，名云砂；黄白 者，名云液；皎
然纯白明澈者，名磷石。此六种并好服，各有时月。其黯黯纯黑，有纹斑斑如铁者，名云胆；
色杂黑而强肥者，名地涿，此二种并不可服。炼之有法，宜精细；不尔，入腹大害人。今江
东惟用庐山者为胜，青州者亦好，以沙土养之，岁月生长。
颂曰∶今兖州云梦山及江州、淳州、杭越间亦有之，生土石间。作片成层可析，明滑光
白者为上。其片有绝大而莹洁者，今人以饰灯笼，亦古扇屏之遗意也。江南生者多青黑，不
堪入药。谨按∶方书用云母，皆以白泽者为贵，惟中山卫叔卿单服法，用云母五色具者。葛
洪《抱朴子》云∶云母有五种，而人不能别，当举以向日看之，阴地不见杂色也。五色并具
而多青者，名云英，宜春服之；五色并具而多赤者，名云珠，宜夏服之；五色并具而多白者，
名云液，宜秋服之；五色并具而多黑者，名云母，宜冬服之；但有青黄二色者，名云砂，宜
季夏服之； 纯白者，名磷石，四时可服也。古方服五云甚多，然修炼节度，恐非文本可
详，不可轻饵也。损之曰∶青、赤、黄、紫、白者，并堪服；白色轻薄通透者，为上；黑者，
不任用，令人淋沥发疮。
【修治】 曰∶凡使，黄黑者，浓而顽；赤色者，经妇人手把者，并不中用。须要光莹
如冰色者，为上。每一斤，用小地胆草、紫背天葵、生甘草、地黄汁各一镒，干者细锉，湿
者取汁了，于瓷锅中安置，下天池水三镒，着火煮七日夜，水火勿令失度，云母自然成碧玉
浆在锅底，却以天池水猛投其中，搅之，浮如蜗涎者即去之。如此三度淘净，取沉香一两捣
作末，以天池水煎沉香汤三升以来，分为三度，再淘云母浆了，日晒任用。
《抱朴子》曰∶服五云之法∶或以桂葱水玉化之为水，或以露于铁器中，以玄水熬之为
水，或以硝石合于筒中埋之为水，或以蜜溲为酪，或以秋露渍之百日，韦囊 以为粉，或以
无颠草樗血合饵之。服至一年，百病除；三年，反老成童；五年，役使鬼神。
胡演曰∶炼粉法∶八、九月间取云母，以矾石拌匀，入瓦罐内封口；三伏时则自柔软，
去矾；次日取百草头上露水渍之；百日，韦囊 以为粉。
时珍曰∶道书言盐汤煮云母可为粉。又云∶云母一斤，盐一斗渍之，铜器中蒸一日，臼
中捣成粉。又云∶云母一斤，白盐一升，同捣细，入重布袋 之，沃令盐味尽，悬高处风吹，
自然成粉。
【气味】甘，平，无毒。
权曰∶有小毒。恶徐长卿，忌羊血、粉。
之才曰∶泽泻为之使，畏 甲及流水。弘景曰∶炼之用矾则柔烂，亦是相畏也。百草上
露乃胜东流水，亦有用五月茅屋溜水者。
独孤滔曰∶制汞，伏丹砂。
【主治】身皮死肌，中风寒热，如在车船上，除邪气，安五脏，益子精，明目，久服轻
身延年（《本经》）。下气坚肌，续绝补中，疗五劳七伤，虚损少气，止痢，久服悦泽不老，
耐寒暑，志高神仙（《别录》）。主下痢肠 ，补肾冷（甄权）。
【发明】保升曰∶云母属金，故色白而主肺。
宗 曰∶古虽有服炼法，今人服者至少，谨之至也。惟合云母膏，治一切痈毒疮等，方
见《和剂局方》。
慎微曰∶《明皇杂录》云∶开元中，名医纪朋，观人颜色谈笑，知病浅深，不待诊脉。
帝召入掖庭，看一宫人，每日昃则笑歌啼号若狂疾，而足不能履地。朋视之曰∶此必因食饱
而大促力，顿仆于地而然。乃饮云母汤，熟寐而失所苦。问之，乃言太华公主载诞，某当主
讴，惧声不能清长，因吃 蹄羹，饱而歌大曲，唱罢觉胸中甚热，戏于砌台，因坠下，久而
方苏，遂病此也。又《经效方》云∶青城山丈人观主康道丰，治百病云母粉方∶用云母一斤，
拆开揉入大瓶内筑实，上浇水银一两封固，以十斤顶火 赤取出，却拌香葱、紫连翘草二件，
合捣如泥，后以夹绢袋盛，于大水盆内摇取粉，余滓未尽，再添草药重捣取粉。以木盘一面，

成都府辛谏议，曾患大风，众医不愈，道丰进此，服之神验。《抱朴子》曰∶他物埋之即朽，
着火即焦；而五云入猛火中经时不焦，埋之不腐。故服之者长生，入水不濡，入火不烧，践
棘不伤。
时珍曰∶昔人言云母壅尸，亡人不朽。盗发冯贵人冢，形貌如生，因共奸之；发晋幽公
冢，百尸纵横。及衣服皆如生人，中并有云母壅之故也。
【附方】旧七，新七。服食云母∶上白云母二十斤薄擘，以露水八斗作汤，分半淘洗二

【《神农本草经》列为上品】
【释名】云华、云珠、云英、云液、云砂、磷石（出自《神农本草经》）。
李时珍说：云母根据五种颜色来命名，详细内容见下文。据《荆南志》记载：华容方台山出产云母，当地人观察云彩出现的地方，在下面挖掘取石，没有不大有收获的，有长达五六尺可以做屏风的，但挖掘时忌讳发出声响。据此，这种石头是云的根基，所以得名云母，而云母的根基，就是阳起石。《抱朴子》中说：服用云母十年，常有云气覆盖在它上面。服用它的母亲以得到它的儿子，这是自然的道理。
【集解】《名医别录》说：云母产于泰山山谷、齐山、庐山以及琅琊北定山的岩石间，二月采集。云华，五色俱全；云英，颜色多青；云珠，颜色多赤；云液，颜色多白；云砂，色青黄；磷石，色正白。
陶弘景说：按《仙经》记载，云母有八种：对着太阳看，颜色青白多黑的，名叫云母；颜色黄白多青的，名叫云英；颜色青黄多赤的，名叫云珠；像冰露一样乍黄乍白的，名叫云砂；黄白色的，名叫云液；皎洁纯白明澈的，名叫磷石。这六种都可以很好地服用，各有适宜的季节。那些暗淡纯黑，有纹路斑斑像铁一样的，名叫云胆；颜色杂黑而且强肥的，名叫地涿，这两种都不可服用。炼制它有方法，应该精细；不然的话，进入腹中会大大伤害人体。现在江东地区只用庐山产的为好，青州产的也不错，用沙土培育它，经过岁月生长。
苏颂说：现在兖州云梦山以及江州、淳州、杭州越州之间也有，生长在土石之间。成片成层可以剥离，明亮光滑洁白的为上品。其中有大片且晶莹洁白的，现在的人用来装饰灯笼，这也是古代扇屏的遗留意趣。江南生产的多数青黑，不堪入药。谨按：医书中使用云母，都以白色泽亮的为珍贵，只有中山卫叔卿单独服用的方法，使用五色俱全的云母。葛洪《抱朴子》说：云母有五种，人们不能分辨，应当举起来对着太阳看，在阴处不见杂色的。五色俱全而多青的，名叫云英，适宜春天服用；五色俱全而多赤的，名叫云珠，适宜夏天服用；五色俱全而多白的，名叫云液，适宜秋天服用；五色俱全而多黑的，名叫云母，适宜冬天服用；只有青黄二色的，名叫云砂，适宜长夏服用；纯白的，名叫磷石，四季都可以服用。古方中服用五云的方法很多，然而修炼的节度，恐怕不是文本所能详述的，不可以轻易服用。损之曰：青、赤、黄、紫、白的，都可以服用；白色轻薄通透的，为上品；黑色的，不可任用，会让人患淋沥病并发疮疡。
【修治】燋氏说：凡是使用的，黄黑色的，浓厚而坚硬；红色的，经过妇人手拿过的，都不中用。必须要求光莹如冰色的，为上品。每一斤，用小地胆草、紫背天葵、生甘草、地黄汁各一镒，干的切碎，湿的取汁，放在瓷锅中，加入天池水三镒，点火煮七个日夜，水火不要失去度数，云母自然变成碧玉浆在锅底，然后用天池水猛烈投入其中，搅拌，浮起像蜗涎一样的就去除掉。这样三次淘洗干净，取沉香一两捣成末，用天池水煎沉香汤三升左右，分三次，再次淘洗云母浆，日晒后使用。
《抱朴子》说：服用五云的方法：有的用桂、葱、水玉化它为水，有的在铁器中接受露水，用玄水熬它为水，有的将硝石合在筒中埋它为水，有的用蜜调和成酪，有的用秋露浸泡一百天，装在韦囊中做成粉，有的用无颠草和樗血混合服用。服用到一年，百病消除；三年，返老还童；五年，役使鬼神。
胡演说：炼粉的方法：八月、九月间取云母，用矾石拌匀，放入瓦罐内封口；三伏天时就会自然变软，去掉矾；第二天取百草头上的露水浸泡它；一百天后，装在韦囊中做成粉。
李时珍说：道书说用盐汤煮云母可以做成粉。又说：云母一斤，盐一斗浸泡它，在铜器中蒸一天，在臼中捣成粉。又说：云母一斤，白盐一升，一起捣细，装入厚重的布袋中，浇灌直到盐味尽失，悬挂在高处风吹，自然成粉。
【气味】甘，平，无毒。
李权说：有小毒。恶徐长卿，忌羊血、粉。
张元素说：泽泻作为引经药，畏 甲及流水。陶弘景说：炼制时用矾石则柔烂，也是相畏的关系。百草上的露水胜过东流水，也有用五月茅屋溜水的。
独孤滔说：能制约汞，伏制丹砂。
【主治】身体皮肤死肌，中风寒热，像在车船上一样晕眩，除邪气，安五脏，益子精，明目，久服轻身延年（《神农本草经》）。下气坚肌，续绝补中，疗五劳七伤，虚损少气，止痢，久服悦泽不老，耐寒暑，志高神仙（《名医别录》）。主下痢肠 ，补肾冷（甄权）。
【发明】保升说：云母属金，所以色白而主肺。
寇宗奭说：古代虽然有服炼法，现在人服用的很少，非常谨慎。只有合云母膏，治疗一切痈毒疮等，方剂见《和剂局方》。
慎微说：《明皇杂录》说：开元年间，名医纪朋，观察人的颜色和谈笑，就知道病的深浅，不需要诊脉。皇帝召他入掖庭，看一个宫人，每天下午就笑歌啼号像狂疾，而且脚不能踩地。纪朋看后说：这一定是因为吃饱后大力气，突然跌倒在地造成的。于是喝云母汤，熟睡后失去了痛苦。问其原因，说是太华公主分娩，我负责唱歌，怕声音不清长，因此吃了蹄羹，吃饱后唱大曲，唱完觉得胸中很热，在砌台上玩耍，因此坠下，很久才苏醒，于是得了这个病。又《经效方》说：青城山丈人观主康道丰，治疗百病云母粉方：用云母一斤，拆开揉入大瓶内筑实，上面浇水银一两封固，用十斤顶火烧红取出，再拌香葱、紫连翘草两件，合捣如泥，后用夹绢袋盛装，在大水盆内摇取粉，余渣未尽，再添草药重捣取粉。用木盘一面，在灰上印一浅坑，铺纸倾粉在内，候干焙之，用面糊丸梧子大。遇到有病者，服用无不有效。知成都府辛谏议，曾患大风，众医不愈，道丰进此方，服用神验。《抱朴子》说：其他东西埋入即朽，着火即焦；而五云进入猛火中经时不焦，埋入不腐。所以服用它的人长生，入水不湿，入火不烧，踩荆棘不伤。
李时珍说：古人说云母壅尸，死者不朽。盗掘冯贵人墓，形貌如生，因而共同奸淫；发掘晋幽公墓，百尸纵横。以及衣服都像活人，中间都有云母壅塞的缘故。
【附方】旧方七个，新方七个。服食云母：上等白云母二十斤薄撕开，用露水八斗作汤，分半淘洗两次。又取二斗作汤，纳芒硝十斤，木器中浸泡二十日，取出绢袋盛装，悬挂在屋上，不要见风日，令其干燥。用鹿皮做囊揉搓它，从早晨到中午，筛去渣滓再揉搓，得到好粉五斗，其余丢弃。用粉一斗纳崖蜜二斤，搅成糊，放入竹筒中，薄削封口漆固，埋在北侧南崖下，入地六尺，覆土。春夏四十日、秋冬三十日出之，应成为水。如果洞洞不消，再埋三十日。此水能治万病，及劳气风疹。每次用温水一合和服之，每日三次。十日，小盒饭变黄；二十日，腹中寒 消；三十日，龋齿更生；四十日，不畏风寒；五十日，诸病皆愈，颜色日少，长生神仙。（《千金方》）
痰饮头痛、往来寒热：云母粉二两（炼过），恒山一两。为末。每服方寸匕，汤服取吐。忌生葱、生菜。（《深师方》）牝疟多寒：云母（烧二日夜）、龙骨、蜀漆（烧去腥）等分。为散。未发前，浆水服钱。（仲景《金匮方》）
小儿下痢赤白及水痢：云母粉半两，煮白粥调食之。（《食医心镜》）
赤白久痢、积年不愈：饮调云母粉方寸匕服。二服，立见神效。（《千金方》）

[Classified as Top Grade in the *Shennong Bencao Jing*]
**Names:** Yunhua, Yunzhu, Yunying, Yunye, Yunsha, Linshi (from *Shennong Bencao Jing*).
Li Shizhen said: Yunmu (Muscovite) is named according to its five colors; details are provided below. According to *Jingnan Zhi*, Yunmu is produced at Fangtai Mountain in Huarong. Locals observe where clouds emerge and dig underneath to extract the stone, invariably achieving great success. Some pieces are five or six chi long and can be used as screens, but one must avoid making noise during excavation. Based on this, this stone is the root of clouds, hence the name Yunmu (Cloud Mother), and the root of Yunmu is Yangqishi (Actinolite). *Baopuzi* states: "After taking Yunmu for ten years, cloud vapor often covers it. Taking its 'mother' to obtain its 'son' follows natural principles."
**Collection and Explanation:** *Mingyi Bielu* states: Yunmu grows in the valleys of Mount Tai, Qi Mountain, Lushan, and between the rocks of Beiding Mountain in Langya. It is harvested in the second lunar month. Yunhua possesses all five colors; Yunying is mostly green; Yunzhu is mostly red; Yunye is mostly white; Yunsha is yellowish-green; Linshi is pure white.
Tao Hongjing stated: According to *Xianjing*, there are eight types of Yunmu: When viewed towards the sun, those that are green-white with much black are named Yunmu; those that are yellow-white with much green are named Yunying; those that are green-yellow with much red are named Yunzhu; those like ice dew that fluctuate between yellow and white are named Yunsha; those that are yellow-white are named Yunye; those that are bright, pure white, and clear are named Linshi. These six types are suitable for consumption, each having a specific season. Those that are dark pure black with patterns resembling iron are named Yundan; those that are mixed black and strong/fat are named Dizhuo. These two types should not be consumed. There is a method for refining them, which requires precision; otherwise, ingestion will severely harm the body. Currently, only Yunmu from Lushan in Jiangdong is considered superior, though Qingzhou's is also good, cultivated in sandy soil over time.
Su Song stated: It is now found in Yunmeng Mountain in Yanzhou, as well as Jiangzhou, Chunzhou, and the Hang-Yue region, growing among earth and stones. It forms sheets in layers that can be split. Bright, smooth, and white specimens are of the highest grade. Some large, crystal-clear sheets are now used to decorate lanterns, retaining the ancient intent of fans and screens. Those produced in Jiangnan are mostly green-black and unsuitable for medicine. Note: Medical texts value white, lustrous Yunmu, except for the single-consumption method of Wei Shuqing from Zhongshan, which uses Yunmu with all five colors. Ge Hong's *Baopuzi* says: There are five types of Yunmu, which people cannot distinguish; one should hold it up to the sun to see if there are no mixed colors in the shade. Those with all five colors but predominantly green are named Yunying, suitable for spring consumption; those with all five colors but predominantly red are named Yunzhu, suitable for summer; those with all five colors but predominantly white are named Yunye, suitable for autumn; those with all five colors but predominantly black are named Yunmu, suitable for winter; those with only green and yellow colors are named Yunsha, suitable for late summer; pure white ones are named Linshi, suitable for all seasons. Ancient formulas for consuming the "Five Yun" are numerous, but the regulations of cultivation are likely too detailed for text and should not be taken lightly. Sun Zhi said: Green, red, yellow, purple, and white are all consumable; white, thin, light, and transparent ones are superior; black ones are unusable and cause strangury and sores.
**Processing:** Jiao Shi said: Generally, yellow-black ones are thick and hard; red ones handled by women are useless. One must select those that are glossy and ice-like, which are superior. For every jin, use Xiaodidanchao (Radix Bupleuri? *Note: Context implies a specific herb, likely distinct*), Zibeitiankui (Achyranthes bidentata var. atrata?), raw Gancao (Licorice Root), and Dihuang juice (Rehmannia Juice), each one yi. Dry herbs are finely chopped, wet ones yield juice. Place in a porcelain pot, add three yi of Tianchi water, and boil over fire for seven days and nights. Do not let the water and fire lose their balance; the Yunmu will naturally turn into a jade-green paste at the bottom. Then, violently throw in more Tianchi water, stir, and remove anything floating like snail slime. Repeat this washing process three times. Take one liang of Chenxiang (Agarwood), grind into powder, decoct in three sheng of Tianchi water, and use this liquid in three portions to wash the Yunmu paste again. Sun-dry and use.
*Baopuzi* states: Methods for consuming the Five Yun: Some dissolve Gui (Cinnamon Twig), Cong (Scallion), and Shuiyu (Quartz) in water; some collect dew in iron vessels and boil with Xuan water; some bury Nitrostone (Niter) in tubes to become water; some mix with honey to form curd; some soak in autumn dew for 100 days and store in leather bags as powder; some mix with Wudiancao and Chu blood to ingest. After one year, hundred diseases are eliminated; after three years, one returns to childhood; after five years, one can command spirits and gods.
Hu Yan said: Method for refining powder: In August or September, take Yunmu, mix evenly with Fanshi (Alum), seal in a clay jar. During the Sanfu period, it becomes soft; remove the alum. The next day, soak with dew from the heads of hundred herbs. After 100 days, process into powder using leather bags.
Li Shizhen said: Daoist texts state that boiling Yunmu in salt soup produces powder. Another says: Soak one jin of Yunmu in one dou of salt, steam in a copper vessel for one day, then pound into powder in a mortar. Another says: Pound one jin of Yunmu with one sheng of white salt finely, put in a heavy cloth bag, pour water until the salt taste is gone, hang in a high place to dry in the wind, and it naturally becomes powder.
**Flavor and Toxicity:** Sweet, neutral, non-toxic.
Li Quan said: Slightly toxic. Adversely affected by Xuchangqing (Polygona multiflori Caulis); avoid sheep blood and starch.
Zhang Yuansu said: Zexie (Alisma Rhizome) acts as an guiding herb; adverse reaction with Jia and running water. Tao Hongjing said: Refining with Alum causes softening and rotting, indicating mutual antagonism. Dew from hundred herbs is superior to east-flowing water; some use water dripping from thatched roofs in May.
Dugu Tao said: Controls mercury, subdues Zhusha (Cinnabar).
**Indications:** Treats dead skin and muscles, wind-stroke with cold and heat, dizziness as if in a cart or boat, expels evil qi, calms the five zang organs, benefits zi jing (essence), brightens the eyes, and with long-term use, lightens the body and prolongs life (*Shennong Bencao Jing*). Directs qi downward, firms muscles, reconnects severed tendons, tonifies the center, treats wulao qishang (five labors and seven injuries), deficiency and shortness of breath, stops dysentery. With long-term use, it beautifies, prevents aging, resists cold and heat, and elevates spiritual aspirations (*Mingyi Bielu*). Treats dysentery with intestinal issues, warms kidney cold (Zhen Quan).
**Elucidation:** Bao Sheng said: Yunmu belongs to Metal, hence its white color and association with the Lung.
Kou Zongshi said: Although ancient methods of consumption and refinement existed, few people consume it today due to extreme caution. Only Yunmu Ointment is used to treat all kinds of carbuncles, toxins, and sores; see *Heji Jufang*.
Shen Wei said: *Minghuang Zalu* records: During the Kaiyuan era, famous doctor Ji Peng could determine the depth of illness by observing a person's complexion and conversation without pulse diagnosis. The Emperor summoned him to the inner quarters to examine a palace maid who laughed, sang, cried, and howled daily like a madman and could not walk. Ji Peng observed and said: This must be caused by eating full and exerting great force, leading to a sudden fall. He prescribed Yunmu Tang (Decoction). The patient slept soundly and was relieved. Upon inquiry, she explained that during the birth of Princess Taihua, she was responsible for singing. Fearing her voice would not be clear and long, she ate trotter soup, became full, sang a grand song, felt intense heat in her chest afterwards, played on a terrace, fell, and took a long time to recover, resulting in this illness. Also, *Jingxiao Fang* records: Kang Daofeng, abbot of Zhangren Temple on Qingcheng Mountain, treated hundred diseases with Yunmu Powder: Take one jin of Yunmu, break apart, rub into a large bottle, pack tightly, pour one liang of Mercury on top to seal, roast over ten jin of top-fire until red-hot, remove, mix with Fragrant Scallion and Zi Lianqiao Cao (Purple Goldenrod Herb?), pound into mud, place in a double-layered silk bag, shake in a large basin of water to extract powder. If residue remains, add more herbs and pound again to extract powder. Use a wooden tray, make a shallow pit in ash, line with paper, pour powder in, wait for drying, and bake. Form pills the size of Chinese bayberry seeds using wheat paste. Effective for any patient. Xin Jianyi, Prefect of Chengdu, suffered from severe leprosy (Feng), unresponsive to other doctors. Kang offered this formula, which proved miraculous. *Baopuzi* states: Other things rot when buried and burn when fired; but the Five Yun do not burn in fierce fire for a long time nor rot when buried. Thus, those who consume it achieve longevity, are not wetted by water, not burned by fire, and uninjured by thorns.
Li Shizhen said: Ancients said Yunmu preserves corpses, preventing decay. When thieves dug up the tomb of Noble Lady Feng, her appearance was like alive, and they defiled her body; when digging the tomb of Duke You of Jin, hundreds of corpses were exposed. Their clothes looked like those of the living, due to the presence of Yunmu preserving them.
**Attached Prescriptions:** Seven old, seven new.
**Consuming Yunmu:** Take twenty jin of premium Baiyunmu (White Muscovite), tear thinly. Use eight dou of dew as soup, divide in half, and wash twice. Take another two dou as soup, add ten jin of Mangxiao (Mirabilite), soak in a wooden vessel for twenty days. Remove, place in a silk bag, hang under the roof, avoid wind and sun, let dry. Rub in a deer-skin bag from morning to noon, sieve residue and rub again, obtaining five dou of fine powder, discard the rest. Mix one dou of powder with two jin of cliff honey, stir into a paste, put in a bamboo tube, seal thinly with lacquer, bury under a south-facing cliff on the north wall, six chi deep, cover with soil. Retrieve after 40 days in spring/summer or 30 days in autumn/winter; it should become liquid. If not fully dissolved, bury for another 30 days. This water treats ten thousand diseases, including labor-qi and wind-rash. Take one he of warm water mixed with it, three times a day.
