太阴玄精（一种矿物药），产于解县，如今解池以及通州、泰州的积盐仓中也有出产，颜色青白且纹理如龟背者品质最佳。采集没有固定时间。解池还有一种盐精，味道更加咸苦，呈青黑色，大的有三四寸长，形状像铁犁铧的尖端，在三月、四月采集。它也主要用于祛除风冷之邪，无毒。又名泥精，大概是玄精的一类。古代医方中不见使用，近代补益药及治疗伤寒时多用此药。其中著名的用法是：治疗伤寒三天后出现的头痛、高热、四肢活动不利，用正阳丹方剂：取太阴玄精、硝石、硫黄各二两，砂一两，将这四味药都细细研磨，放入瓷瓶中，用泥密封加固，用半斤火炭围绕瓶子燃烧约半天时间，待药料变为青紫色时停止加热。冷却后取出，用腊月积雪水拌和均匀湿润，放入瓷罐中，置于房屋背后北面的阴凉处阴干，又埋入地下十四天，取出后细细研磨，用面糊调和制成丸药，大小如鸡头实（芡实）。先用热水沐浴后，用艾叶汤送服一丸。盖上衣物，以出汗为痊愈标志。
密陀僧（一种矿物药），《神农本草经》未记载其产地。注释说：产于波斯国。如今岭南、福建等地的银铜冶炼处也有出产，它是炼银铅后的余渣。最初开采矿石时，银和铜混杂。先用铅一同煎炼，银随铅一起析出。又采集山木树叶烧成灰，开辟地面作炉，填满灰烬。这些灰吸收了铅银的气息，放置久了便形成这种物质。现在使用的密陀僧，往往就是这种产物，未必是从胡地（西域）进口来的。形状像黄龙齿且质地坚硬沉重的，品质最佳。

Taiyin Xuanjing (Taiyin Black Crystal/Mineral Salt), produced in Jie County. It is also found in the salt storage warehouses of Jiechi, Tongzhou, and Taizhou today. The best quality is greenish-white with a texture resembling a turtle's shell. It can be harvested at any time. There is also Yanjing (Salt Essence) in Jiechi, which tastes even more salty and bitter, appears dark green-black, and the larger pieces are three or two cun long, shaped like the tip of an iron plowshare. It is harvested in March and April. It is also mainly used to dispel wind-cold and is non-toxic. It is also known as Nijing (Mud Essence), which is likely a type of Xuanjing. It was not used in ancient prescriptions but is frequently used in modern tonics and treatments for Shanghan (Cold Damage Syndrome). A notable prescription is Zhengyang Dan: For treating Shanghan after three days, presenting with headache, high fever, and stiffness/impaired movement of the four limbs, take Taiyin Xuanjing, Xiaoshi (Niter/Saltpeter), and Huangshi (Sulfur), each 2 liang, and Sha (Borax) 1 liang. Grind these four substances finely together, place them in a porcelain bottle, seal it tightly with mud, and heat it by surrounding the bottle with half a jin of hot charcoal for about half a day. Stop heating when the medicine turns blue-purple. After cooling, remove it, mix evenly with snow water collected in the twelfth lunar month until moist, place it in a porcelain jar, dry it in the shade under the north side of the house, and bury it in the ground for fourteen days. Remove it, grind it finely, and bind it with wheat paste to form pills the size of Qianshi (Euryale Seed). Take one pill washed down with Artemisia Decoction after first taking a hot water bath. Cover with clothing; recovery is indicated by sweating.
Miduoseng (Litharge), the Benjing (Shennong Bencao Jing) does not record its origin. The annotation states: it comes from Persia. Today, it is also found in silver and copper smelting areas in Lingnan and Minzhong (Fujian). It is the dregs/residue from refining silver and lead. Initially, when mining ore, silver and copper were mixed. Lead was added to smelt them together, allowing the silver to separate out with the lead. Then, mountain tree leaves were collected and burned to ash. A pit was dug to serve as a furnace, filled with this ash. The ash absorbed the qi of lead and silver, and after a long period of sitting, this substance formed. The Miduoseng used today is often this kind of product, and it may not necessarily come from Hu (Western Regions). The best quality resembles the teeth of a yellow dragon and is hard and heavy.
