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.
