Dai Zhe (Hematitum): It has a bitter taste and a cold nature. It primarily treats Gui Zhu (a contagious chronic deficiency syndrome), Zei Feng (pathogenic evil wind), and Gu Du (diseases caused by insect poison). It kills Jing Wu E Gui (pathogenic evil spirits), eliminates toxic evil Qi in the abdomen, and treats Chi Wo Lou Xia (red vaginal discharge or continuous dripping in women). It is also known as Xu Wan.
It grows in mountain valleys.
The Ming Yi Bie Lu (Separate Records of Famous Physicians) states: It is also known as Xue Shi. It is produced in the State of Qi. Its color is reddish with a bluish tint, resembling a rooster's comb, and it has a luster. Those that do not fade when used to dye fingernails are of good quality. There is no fixed season for harvesting.
Commentary: The Shuo Wen Jie Zi (Explaining Graphs and Analyzing Characters) states: "Zhe" means red earth. The Bei Shan Jing (Classic of the Northern Mountains) states: Mount Shaoyang contains abundant high-quality Zhe. The Guan Zi, Chapter on Earth Numbers, states: Where there is Zhe on the mountain, there is iron below. The Fan Zi Ji Ran states: Shi Zhe (stone ochre) is produced in Qi Commandery; the red variety is superior. Shu Zhe is produced in Shu Commandery. According to the Yuan He Jun Xian Zhi...
Rong Yan (Halitum Rubrum): It primarily improves vision, treats eye pain, benefits Qi, strengthens muscles and bones, and removes toxic Gu. Da Yan (Large Salt): Causes vomiting (The Tai Ping Yu Lan cites: It primarily treats heat accumulation in the intestines and stomach. The Da Guan Ben Cao prints this in black characters). Lu Yan (Bittern Salt): It has a bitter taste and a cold nature. It primarily treats severe heat, Xiao Ke (wasting and thirsting disorder) with manic irritability, eliminates evil Qi, expels internal Gu Du, and softens the skin and flesh (The Tai Ping Yu Lan cites: It is also known as Han Shi, and it improves vision and benefits Qi). It grows in pools and marshes (Old editions listed three types; they are now combined).
The Ming Yi Bie Lu states: Rong Yan is also known as Hu Yan. It is produced in Hu Yan Mountain, as well as in Xi Qiang, Bei Di, Jiu Quan, and the southeast corner of Fulu City. The variety from the North Sea is green/blue; the variety from the South Sea is red. It is harvested in the tenth month. Da Yan is produced in Handan and also in Hedong. Lu Yan is produced in the Hedong Salt Pool.
Commentary: The Shuo Wen Jie Zi states: "Yan" (salt) means salty. In ancient times, Su Sha Shi first made boiled sea salt. "Lu" refers to the saline lands of the West. The character derives from the "West" radical, resembling the shape of salt. There is a Lu County in Anding Commandery. In the East, it is called Chi; in the West, it is called Lu Yan. The Hedong Salt Pool is 51 li long, 7 li wide, and 116 li in circumference. The Bei Shan Jing states: Looking south from Mount Jing, one can see the Ze of Salt Peddlers. Guo Pu states: This is the salt pool in Jie County. It is currently located in Yishi County, Hedong. Commentary: It is in Anyi Yuncheng, Shanxi.
