苏恭云∶真者，出蒲州虞乡县东亭谷窟及薛集窟中，有块如鸡卵者为真。今南方医人多使之。

\r云母\ph8.bmp\r，生泰山山谷、齐卢山及琅琊北定山石间。今兖州云梦山及江州、

堪入药。二月采，其片绝有大而莹洁者，今人或以饰灯笼，亦古屏扇之遗事也。谨按∶方书
用云母，皆以白泽者为贵，惟中山卫叔卿单服法，云母五色具者。盖《本经》所谓一名云华
者，是一物中而种类有
以向日看其色，详占视之，乃可知正尔，于阴地视之，不见其杂色也。五色并具而多青者，
名云英，宜以春服之；五色并具而多赤者，名云珠，宜以夏服之；五色并具而多白者，名云
液，宜以秋服之；五色并具而多黑者，名云母，宜以冬服之；但有青、黄二色者，名云砂，
宜以季夏服之； 纯白者，名磷石，四时可服也。然则医方所用正白者，乃磷石一种耳。
古之服五云之法甚多，陶隐居所撰《太清诸石药变化方》言之备矣。今道书中有之，然修炼
节度，恐非文本可详，诚不可轻饵也。又西南天竺等国出一种石，谓之火齐，亦云母之类也，
色如紫金，离析之。
石胆，产于羌道山谷羌里句青山，如今只有信州铅山县出产。它生长在铜矿坑中，开采后经过煎煮提炼而成。也有天然生成的，更为珍贵。颜色均为深碧色。用于吐出风痰的药物中，使用它效果最快。在二月庚子、辛丑日采集。苏恭说：真正的石胆，出产于蒲州虞乡县东亭谷窟及薛集窟中，有像鸡蛋大小的块状物才是真品。如今南方医生多使用它。又在著作中说明：石胆放置久了会变绿，击碎后，内部也是青色的。其次出产于上饶、曲江铜矿坑间的，颗粒细小且有棱角，像钗股或米粒一样。本草注中说：伪品是用醋揉搓青矾制成的。如今并非如此，只是选取粗劣的石胆混合硝石熔化制成。如今那些块头大、颜色浅、浑然无纹理、敲击则碎裂没有棱角的，就是这种伪品。也有夹杂石头的，是削取石胆床（生成石胆的基底），在熔化制造时投入消汁中，等到凝固时就粘合在一起了。
云母，产于泰山山谷、齐卢山以及琅琊北定山的石缝间。如今兖州云梦山以及江州、濠州、杭州、越州之间也有出产，可以入药。二月采集，其中片状极大且晶莹洁白的，如今有人用来装饰灯笼，这也是古代屏风扇子的遗留习俗。谨按：方书中使用云母，都以白泽色为珍贵，只有中山卫叔卿单独服用的方法中提到，云母五色俱全的。大概《本经》所说的名为“云华”的，是同一种物质但种类不同。对着太阳看它的颜色，仔细占卜观察，才能知道正确情况，在阴处观看，就看不到杂色了。五色俱全而青色多的，名叫云英，适宜在春季服用；五色俱全而红色多的，名叫云珠，适宜在夏季服用；五色俱全而白色多的，名叫云液，适宜在秋季服用；五色俱全而黑色多的，名叫云母，适宜在冬季服用；只有青、黄两种颜色的，名叫云砂，适宜在长夏（季夏）服用；纯白色的，名叫磷石，四季都可以服用。那么医方中所用的正白色云母，不过是磷石这一种罢了。古代服用五种云母的方法很多，陶隐居所撰写的《太清诸石药变化方》说得非常详尽。如今道书中有记载，但是修炼的步骤和法度，恐怕不是文本所能详述的，确实不可以轻易服用。另外西南天竺等国出产一种石头，叫做火齐，也是云母的一类，颜色像紫金，将其分离析出。
Bianqing (Mineral Azurite), its detailed description is listed under the entry for Lvqing (Green Azurite).
Shidan (Chalcanthite / Copper Sulfate), originally produced in Qiangdao Valley, Qiangliju Qingshan, but currently only found in Yanshan County, Xinzhou. It grows in copper mines and is obtained through mining followed by boiling and refining processes. Naturally occurring specimens are also available and are considered particularly precious. All exhibit a deep emerald-green color. It acts most rapidly when used in medicines intended to induce vomiting of wind-phlegm. It should be harvested on Gengzi or Xinchou days in the second lunar month. Su Gong stated: Genuine Shidan comes from Dongting Valley caves and Xueji Caves in Yuxiang County, Puzhou; those with lumps resembling chicken eggs are genuine. Physicians in the southern regions frequently use it today. He further explained: Over time, Shidan turns green; when broken open, its interior is also blue-green. The next best quality comes from between the copper mines of Shangrao and Qujiang; these are fine-grained with sharp edges, resembling hairpin shafts or rice grains. The commentary on Bencao states that counterfeit versions are made by knealing Qingfan (Green Alum) with vinegar. This is no longer the case; nowadays, inferior Shidan is simply mixed with Nixiao (Saltpeter) and melted together. Those that are large in size, pale in color, lacking distinct texture, and shatter into fragments without sharp edges upon impact are such counterfeits. Some may contain embedded stones; this occurs when the bedrock supporting Shidan formation is shaved off and added to the molten mixture during production, causing them to adhere upon solidification.
Yunmu (Muscovite Mica), grows among the rocks in the valleys of Mount Tai, Qilu Mountain, and Beiding Mountain in Langya. Currently, it is also found in Yunmeng Mountain in Yanzhou, as well as Jiangzhou, Haozhou, Hangzhou, and Yuezhou, and can be used in medicine. It is harvested in the second lunar month. Among the flakes, those that are exceptionally large and crystal clear are sometimes used by people today to decorate lanterns, which is a remnant of the ancient practice of using them for screens and fans. According to careful examination: Medical texts value white Yunmu above all others. However, the method described by Wei Shuqing of Zhongshan for single-substance ingestion specifies Yunmu possessing all five colors. This likely refers to what the *Benjing* calls "Yunhua," indicating that while they are the same substance, there are different varieties. One must observe their colors facing the sun and examine them carefully to determine their true nature; viewed in shade, impurities are not visible. Those possessing all five colors but predominantly blue are named Yunying and are suitable for consumption in spring; those predominantly red are named Yunzhu and are suitable for summer; those predominantly white are named Yunye and are suitable for autumn; those predominantly black are named Yunmu and are suitable for winter; those possessing only blue and yellow colors are named Yunsha and are suitable for late summer; pure white ones are named Linshi and can be taken in any season. Therefore, the pure white Yunmu used in medical prescriptions is actually just one type, namely Linshi. There were many ancient methods for ingesting the five types of Yunmu, thoroughly discussed in Tao Hongjing's *Taiqing Zhu Shi Yao Bianhua Fang*. These are recorded in Daoist scriptures, but the specific protocols and degrees of refinement cannot be fully detailed in text, so they should certainly not be taken lightly. Additionally, countries in the southwest such as Tianzhu (India) produce a stone called Huoji, which is also a type of Yunmu; it has a color resembling purple gold and can be separated and analyzed.
