[Copper Pyrites / Ziran Tong]
Pungent in flavor. Enters the Foot-Jueyin Meridian (Liver Meridian of Foot-Jueyin). Its primary function is to treat fractures and injuries, knit bones and sinews, dispel blood stasis, and alleviate pain. Fractures inevitably result in blood stasis obstructing the meridians. One must examine the deficiency or excess pattern and assist with herbs that nourish blood, tonify qi, and warm the meridians. It is mined from copper pits. It should be calcined over fire, quenched in vinegar seven times, ground finely, and processed by levigation with licorice water.
[Copper Acetate / Tong Qing]
Sour in flavor, neutral with slight toxicity. Enters the Hand-Taiyin, Hand-Shaoyang, Foot-Taiyin, and Foot-Jueyin Meridians. Its primary function is to induce vomiting of wind-phlegm, stop bleeding from sores, regulate qi pain, and kill parasites effectively. Ingestion damages blood. It is prepared by scraping copper treated with vinegar. For head lice, a mixture of copper acetate and alum powder applied locally is effective. For gan gangrene (a rapidly progressing, corrosive oral disease), one qian of white scale scraped from a urinal pot, calcined, mixed with three fen of copper green and one fen of musk, applied topically yields immediate cure. Also known as Tong Lu.
[Lead Carbonate / Hu Fen]
Sweet, cold, and pungent in flavor. Enters the Hand-Taiyin, Hand-Shaoyang, Foot-Taiyin, and Foot-Jueyin Meridians. Its primary function is to settle phlegm, calm the spirit, brighten the eyes, kill parasites, darken hair, and treat malignant sores. Combined with Dang Gui, it knits bones and sinews. Combined with millet, it treats abdominal bi-syndrome (abdominal masses resembling turtles). Combined with lard, it treats accidental ingestion of gold or silver. Taken alone as a decoction, it resolves sulfur toxicity. Its nature carries yin toxicity, damaging the heart and stomach. Also known as Hu Fen.
[Lead Tetroxide / Huang Dan]
Salty, cold, and heavy in nature. Enters the Hand-Taiyin, Hand-Shaoyang, Foot-Taiyin, and Foot-Shaoyin Meridians. Its primary function is to settle phlegm and stop惊悸 (palpitations/fright). Applied alone to yellow water blisters, it is miraculous. Combined with Long Gu (Dragon Bone) and Mu Li (Oyster Shell), it treats cardiac fright and palpitations. Also known as Huang Dan.
[Litharge / Mi Tuo Seng]
Pungent, neutral, with slight toxicity. Enters the Hand-Taiyin, Hand-Shaoyang, Foot-Taiyin, and Foot-Jueyin Meridians. Its primary function is to settle phlegm, calm fright, stop bleeding, and dissipate swelling. Split open a steamed bun, place litharge powder inside, and clamp it under the armpit to treat axillary osmidrosis (fox odor). Ingestion causes coldness in the middle jiao.
[Hematite / Dai Zhe Shi - *Note: Name not explicitly stated in source text segment, translated based on content*]
Pungent, neutral, with toxicity. Enters the Foot-Jueyin Meridian. Its primary function is to treat visual obstructions, blood stasis, corrosion, and necrotic flesh. It treats difficult labor in women, epigastric and abdominal pain, and menstrual disorders with five types of strangury. It can be calcined and quenched in vinegar, or boiled for juice. If lips are swollen, black, painful, and itching intolerably, grind a coin on stone to obtain juice, mix with lard, and apply several times for cure. For sudden blindness, instilling juice ground on stone into the eyes is effective.
[Iron / Tie]
Pungent, neutral, with toxicity. Enters the Hand-Shaoyin, Foot-Taiyin, and Foot-Jueyin Meridians. Its primary function is to calm the heart, soothe the liver, settle fright, treat mania, resolve abscesses, and detoxify. Iron filings struck off an anvil are called Tieluo (Iron Drops), which treat rage-induced mania; powdered and applied, they are good for tinea. Dust-like particles are called Tiejing (Iron Essence). Rust formed on vessels is called Tiexiu (Iron Rust). Substances extracted by soaking in salt and vinegar are called Tiehua (Iron Flowers). It is incompatible with Magnetite and Gleditsia Sinensis; cooking pots made of Gleditsia wood crack when used, indicating mutual antagonism. True steel sand primarily breaks accumulations and soothes the liver. Combined with Coptis Chinensis and Sophora Flavescens, it treats heat-type distension and diarrhea.
