[Danfan (Chalcanthite)]
Taste: sour, bitter, pungent. Nature: cold. Toxicity: toxic. Meridian tropism: not recorded. Actions: clears heat, kills parasites, arrests convulsions and epilepsy, induces vomiting of wind-phlegm. The brighter in color, the better.
Commentary: The efficacy of Danfan is generally similar to that of Bai Fan (Alumen). It is slightly superior only in its ability to arrest convulsions.
[Mengshi (Calamine or Qing Meng Shi)]
Taste: pungent, sweet. Nature: neutral. Toxicity: toxic. Meridian tropism: Lung, Large Intestine, Stomach, San Jiao. Actions: sweeps away old phlegm, reduces food stagnation. Should be ground into fine powder for use.
Commentary: The pungency of Mengshi suits the Lung, and its sweetness suits the Stomach. The Large Intestine is the official organ responsible for transmission for the Lung, hence the herb also enters this meridian. This herb severely damages Yuan Qi (Original Qi) and should not be used indiscriminately.
[Wumingyi (Hematite or Pyrolusite)*]
Taste: sweet. Nature: neutral. Toxicity: non-toxic. Meridian tropism: not recorded. Actions: treats traumatic injuries from metal weapons, fractures, and internal damage; relieves pain, promotes tissue regeneration and flesh growth, resolves carbuncles, sores, swelling, and toxicity.
Commentary: People within the seas say: Stone Wumingyi is extremely rare, while Earth Wumingyi is not very precious. Could it be that what was described in the *Shennong Ben Cao Jing* (*Classic of the Divine Farmer's Materia Medica*) refers to stone Wumingyi, whereas what is available now is earth Wumingyi? When using, grind with vinegar and apply to the affected area.
*[Note: The text describes properties like "white jade dust", "nourishes spirit", "clears eyes", which often refer to minerals like Quartz or specific salts, but strictly translating the provided text without adding external drug names unless implied by context. The text mentions "Yu Xie" (Jade Dust/Particles) in the commentary, suggesting the herb might be a white mineral. However, based on standard TCM materia medica sequences, this section often corresponds to *Qing Yan* or similar, but I will translate the text as is.]*
[Qing Yan / Jade Particles - inferred from context "Yu Xie"]
Taste: sweet. Nature: neutral. Toxicity: non-toxic. Meridian tropism: Lung. Actions: eliminates irritability, quenches thirst, nourishes the spirit (Shen), brightens the eyes, calms the heart, settles fright, removes scars, moistens hair, assists the voice and throat, beautifies the complexion. Crush into rice-sized grains, soak in vinegar until it dissolves into mud. Avoid using with Deer Antler (Lujiao); incompatible with Winter Flower (Kuandonghua).
Commentary: Yu Xie (Jade particles/dust) is white in color and moist in nature, making it suitable for entering the Lung meridian. If the Lung is nourished, how can symptoms such as irritability and thirst arise? Regarding its ability to remove scars, etc., this is also because the Lung governs the skin and hair, so its effects inevitably extend there.
[Ziran Tong (Natural Copper / Pyrite)]
Taste: pungent, neutral. Nature: neutral. Toxicity: non-toxic. Meridian tropism: not recorded. Actions: breaks up accumulations, treats fractures, reconnects bones and tendons, disperses blood stasis, drains pus, relieves pain, settles fright, and also treats postpartum blood stasis and pathogenic factors. Preparation: Must be crushed, boiled in Licorice Decoction (Gancao Tang), soaked in vinegar overnight, wrapped in mud, calcined, and then ground into fine powder.
Commentary: Ziran Tong is actually a stone produced in copper mines. Its color is greenish-yellow like copper, and since it does not require smelting from ore, it is named thus. Zhu Danxi said: Ziran Tong is considered by the world to be an essential herb for bone setting. However, one does not know that bone setting relies on tonifying Qi and Blood, and tonifying the Stomach and Kidney. Quack doctors only hope for quick results and use it for profit, unaware of the disaster caused by its drying and dispersing nature.
Lei Gong said: Shi Sui Qian (Stone Marrow Lead) is Ziran Tong. Do not use Fang Jin Ya in prescriptions; Fang Jin Ya truly resembles Shi Sui Qian. If mistakenly ingested, it causes fatal vomiting. Shi Sui Qian looks like dry silver mud and has a slightly sweet taste. If harvested, first crush it, boil together with Gancao (Licorice) decoction for one Fu period (two hours), strain and let dry. Pound in a mortar, sieve again, soak in vinegar overnight until dawn. Coat a porcelain vessel with Liu Yi Ni (Six-One Mud). Fill with about three Sheng (approx. 300ml+). Place over mild and strong fire, nurture for three days and nights until dry. Cover tightly with a lid and seal with mud, calcine for two Fu periods, remove soil, and grind into powder. For processing five Liang, use two Yi (approx. 24 Liang) of vinegar as the limit.
