[Iron Filings / Tie Luo]
Taste: Pungent, Sweet. Nature: Neutral. Toxicity: Non-toxic.
Indications: Primarily treats malignant sores caused by wind-heat, carbuncles, ulcers, scabs, and skin diseases such as tinea where pathogens reside in the skin; clears heat from the chest and diaphragm, relieves restlessness caused by food stagnation, and removes black spots (melanosis). Ri Hua Zi stated: It treats palpitations and fright, all types of wounds caused by venomous snakes, insects, silkworms, and lacquer tree contact, intestinal wind with hemorrhoids, rectal prolapse, epidemic febrile diseases, and can be used to dye hair and beard black. Iron filings are the flakes that fall off iron sheets during forging. Also known as: Iron liquid, which can be used to dye things black.
[Chang Shi / Longstone]
Taste: Sweet. Toxicity: Non-toxic.
Indications: Primarily treats metal injuries (trauma from sharp objects), restlessness and fullness with internal heat, qi obstruction in the chest and diaphragm, and indigestion. Also known as: Tiao Tie (Jumping Iron).
[Unnamed Section - Likely Magnetite / Cishi]
Nature: Neutral, slightly warm.
Indications: Primarily improves vision, dissolves phlegm (note: original text says "hua tong" [transform copper], likely a textual variant or specific alchemical reference, but clinically often associated with transforming phlegm or aiding digestion in mineral drugs; literal translation used here), treats palpitations, stabilizes heart qi, treats pediatric wind-epilepsy, and addresses vaginal prolapse and rectal prolapse.
[Unnamed Section - Likely Hematite / Daizhe Shi]
Indications: Primarily treats sudden wind pathogens, stops abdominal pain caused by blood masses (blood stasis) postpartum, and sore throat with heat obstruction (bi syndrome). The herb should be heated until red-hot, then immersed in wine, and drunk while hot. People at the time referred to blood masses as "children's pillow," which appears immediately after childbirth, causing unbearable pain; if a hammer is unavailable, an axe may be used for crushing.
[Unnamed Section - Likely Iron Powder / Tie Fen]
Indications: Primarily strengthens muscles and increases pain tolerance. Another view states it is used to make wrought iron. Ri Hua Zi stated: Iron tastes pungent, is neutral, and is toxic. Antagonistic substances include magnetite and charcoal ash; it can counteract the toxicity of Shitingzhi (a mineral drug).
[Unnamed Section - Pumice / Fushi]
Taste: Salty. Nature: Cold. Toxicity: Non-toxic.
Indications: Primarily treats blindness (qing mang), eye nebulae (pterygium/plica), skin nebulae, and pterygion, as well as lacquer dermatitis. Originates from the South Sea. It is said to be formed from sea foam adhering to ordinary crab shells over many years, turning into stone, and floating out during high tides. Similar stones form in caves over long periods. These must be finely ground and processed by water levigation (shui fei) before being combined with other herbs. It is effective for eye applications. Ri Hua Zi stated: It is cooling. It resolves poisoning from all herbs and insects, induces labor and expels the fetus, treats blood vertigo, and eliminates epidemic febrile diseases. It should be taken by grinding with cooked water. Additionally: Floating stone (Fushi) is neutral and non-toxic. It quenches thirst, treats strangury (lin syndrome), and neutralizes wild beast toxins. Rubbing with vinegar and applying externally also resolves mineral poison.
[Unnamed Section - Talc / Huashi]
Taste: Pungent, Bitter. Nature: Cold. Toxicity: Non-toxic.
Indications: Primarily treats body heat, qi stagnation in the stomach, cold limbs and厥 (jue syndrome), promotes urination, unblocks blood vessels, improves vision, removes eye nebulae and blurred vision, expels three types of parasites from the lower jiao, kills insect toxins, relieves polydipsia (xiaoke), directs qi downward, and clears pathogenic factors from the hypochondrium and lungs. Originates from Changzi Valley, Mount Tai, and Linzi. Currently, only Luzhou produces it. The texture resembles horse teeth, square-shaped, smooth and lustrous, with a jade-like color. This stone resembles gypsum but is distinguished by its denser, larger, and longitudinally striated structure. Harvest: At any time.
