此即用画绿色者，亦出空青中，相带挟。今画工呼为碧青，而呼空青作绿青，正反矣。

绿青：味酸，性寒，无毒。主要功效为补益元气，治疗鼻渊（鼻塞流涕），止住泄泻和痢疾。产于山北阴凉的洞穴中，颜色青白。
这就是用来绘制绿色的颜料，也出产于空青矿中，与空青相伴共生。现在的画工称之为“碧青”，而将空青称为“绿青”，这正好弄反了。
铁落：味辛、甘，性平，无毒。主治风热病，恶疮，溃疡疽疮及结痂，皮肤中的疥癣之气。清除胸膈间的余热，改善食欲不振，缓解心烦，去除黑痣。又名“铁液”，可以用来染黑皂角。产于牧羊的平坦沼泽地带以及城墙边，或者析城等地，采集没有固定时间。
铁：主要功效为坚固肌肉，耐受疼痛。
微寒：主要功效为治疗下部疾病及脱肛。
味甘，性平，无毒。主治金创（金属利器造成的创伤），烦闷心中发热，胸膈间气机阻塞，食物不消化。又名“跳铁”。
铁精：性平，微温。主要功效为明目，溶解铜。治疗惊悸，安定心气，小儿风痫，去除颓积，治疗脱肛。
铁落，是用于染皂的铁浆。生铁，是指未经过锻造、枪击、煮饭等加工的原始铁块。钢铁，是将生铁和熟铁混合冶炼而成，用来制作刀剑的工具。
铁（此处原文可能有误或指代不明，结合上下文推测为对铁的进一步描述或另一条目，但原文仅列标题及引文）：[《新修》五八页，《大观》卷四，《政和》一一五页]
味辛，微寒。主治咳嗽气逆，胃反呕吐，惊痫，癫狂疾病，清除热邪，降逆下气。止住小便频多，清除毒热引起的脐部挛急，治疗金创出血。经过炼化可变成“九光”物质。长期服用可以通灵达神。产于蜀郡的平坦沼泽地。又名“铅华”，生于铅矿之中。
就是现在通过熬炼铅所得到的黄丹，用于绘画，世俗方剂中也很少使用，只有《仙经》中涂抹丹炉时需要用到此物。所谓化成“九光”，应当是指制成“九光丹”作为丹炉材料罢了，并没有其他的变炼方法。
[Luqing (Green Malachite)]
Taste: Sour. Nature: Cold. Toxicity: Non-toxic. Main actions: Tonifies Qi, treats rhinorrhea (nasal discharge), and stops diarrhea and dysentery. It grows in caves on the shady (north) side of mountains and is greenish-white in color.
This refers to the material used for painting green; it also occurs within deposits of Kongqing (Blue Malachite), growing alongside it. Contemporary painters call it "Biqing" (Emerald Green), while referring to Kongqing as "Luqing," which reverses the traditional nomenclature.
[Tieluo (Iron Shavings)]
Taste: Pungent, Sweet. Nature: Neutral. Toxicity: Non-toxic. Main actions: Treats wind-heat, malignant sores, ulcers, carbuncles, scabs, and pruritus caused by parasites in the skin. Clears residual heat from the chest and diaphragm, improves poor appetite, relieves mental restlessness, and removes black spots. Also known as "Tieye" (Iron Liquid); it can be used to dye soap black. It is found in flat marshy areas where sheep graze, near city walls, or at Xicheng. It can be harvested at any time.
[Tie (Iron)]
Main actions: Firms muscles and increases pain tolerance.
[Wei Han (Slightly Cold)]
Nature: Slightly cold. Main actions: Treats lower body disorders and rectal prolapse.
[Shengtie (Pig Iron/Raw Iron)]
Taste: Sweet. Nature: Neutral. Toxicity: Non-toxic. Main actions: Treats metal wounds, irritability with internal heat, qi stagnation in the chest and diaphragm, and indigestion. Also known as "Tiaotie."
[Tiejing (Iron Essence)]
Nature: Neutral, slightly warm. Main actions: Brightens the eyes, dissolves copper. Treats palpitations and fright, stabilizes Heart qi, treats pediatric wind-calcium epilepsy, eliminates accumulations, and treats rectal prolapse.
Tieluo is the iron slurry used for dyeing black. Shengtie refers to raw iron that has not been subjected to hammering, piercing, or boiling in cauldrons. Gangtie (Steel) is produced by smelting a mixture of raw iron and wrought iron to make swords and knives.
[Qiandan (Lead Tetroxide/Minium)]
Taste: Pungent. Nature: Slightly cold. Main actions: Treats cough and rebellious qi, gastric regurgitation, fright and epilepsy, mania, clears heat, and directs qi downward. Stops frequent urination, eliminates toxic heat causing umbilical contraction, and treats bleeding from metal wounds. When refined, it transforms into "Jiuguang" (Ninefold Radiance). Long-term consumption enhances spiritual clarity. It originates from flat marshy areas in Shu Commandery. Also known as "Qianhua" (Lead Flour), it is derived from lead.
It refers to the yellow lead oxide currently produced by roasting lead, used in painting. It is rarely used in secular medical formulas; only the *Xianjing* (Classic of Immortals) mentions its use in coating alchemical furnaces. The phrase "transforming into Jiuguang" likely refers to preparing "Jiuguang Dan" for use as furnace lining, rather than implying other chemical transformation methods.
