[Realgar]
Bitter, neutral and cold. It primarily treats chills and fever, lymphatic tuberculosis (Shu Lou) and malignant sores, carbuncles, hemorrhoids, and necrotic tissue. It kills spirits, evil ghosts, pathogenic factors, and the venom of a hundred insects, and protects against weapons.
After calcination and ingestion, it lightens the body and leads to immortality. Also known as Huangshi Shi (Yellow Food Stone). Grows in mountain valleys.
Wu Pu records: Realgar, Shennong states its flavor is bitter. Dan Realgar exists on the north side of mountains, but grows on the south side, hence called "Xiong" (Male), being the male aspect of Cinnabar, thus named Realgar.
Mingyi Bie Lu records: Grows in the southern areas of Wudu Commandery and Dunhuang Commandery. Can be harvested at any time.
Commentary: The Classic of Mountains and Seas (Western Regions) states: Below high mountains, there is much Realgar. Guo Pu stated: In the third year of Taixing during the Jin Dynasty, a landslide occurred in Gaoping Commandery, from which thousands of jin of Realgar emerged. Baopuzi · Chapter on Immortal Drugs states: Realgar should be obtained from Mount Wu, pure without impurities, red like a rooster's comb, shining brightly; only this can be used for immortal drugs. Those that are purely yellow resembling Realgar but lacking red luster cannot be used for immortal drugs, but only for treating illnesses.
[Pyrite / Sulfur] (Note: "Liu" was traditionally written as "Liu" (Sulfur). Tai Ping Yu Lan cites it as "Liu", which is correct.)
Acid, warm. It primarily treats vaginal erosion/ulceration in women, abscesses, hemorrhoids, and foul blood, strengthens bones and tendons, removes scalp baldness, and can melt gold, silver, copper, and iron. (Tai Ping Yu Lan citation: Pyrite...)
Wu Pu records: Sulfur, also known as Shiliu Huang. Shennong, the Yellow Emperor, and Lei Gong state its flavor is salty and toxic; Yi He and Bian Que state its flavor is bitter and non-toxic. Some grow in Yiyang, some in Hexi. Some appear in five colors; the yellow one is Pan water stone liquid (Pan is the ancient character for Alum). When burned, those producing purple flames are harvested in August and September to treat women...
Mingyi Bie Lu records: Grows on Muye Mountain in Donghai, and on the western sides of Taihang River and West Mountains. It is Alum stone liquid.
Commentary: Fanzi Jiran states: Pyrite originates from Hanzhong. It also states: Liu Feng consumed Pyrite and appeared younger. Liu Kui, annotating Wu Du Fu, states: Liuhuang is the essence of earth.
[Orpiment]
Pungent, neutral. It primarily treats malignant sores, scalp baldness with scabs, scabies, kills poisonous insects and lice, treats body itching, pathogenic factors, and various toxins. After calcination. Long-term consumption lightens the body, increases lifespan, and prevents aging. Grows in mountain valleys.
Wu Pu says: Magnetite, also known as Ci Jun. (Note: Textual error likely present here as Magnetite is described under Orpiment section in source text).
Mingyi Bie Lu records: Grows in Wudu Commandery, originating from the same mountains as Realgar. On the shady side of these mountains where gold exists, the essence of gold fumes upon it, generating Orpiment. Can be harvested at any time.
