（赤铜屑，就是打铜时落下的碎屑。也可以用红铜用火加热后用水淬火，铜屑也会自然脱落，用水淘洗干净。取上好白酒放入砂锅中炒，见到火星冒出时取出，研磨成粉末。使用两伏的时间去除土性，再研磨得像粉一样细。凡是修治，以五两铜屑配两镒醋为限度。现在的人只用火煅和醋淬七次，研磨细后用水飞法处理。有一种说法是：经过炮制后半年才可以入药，否则会导致人死亡。）
（生铜和熟铜表面都会产生青绿色的锈迹，这是铜的精华。大块的称为空绿，次一等的称为空青。铜青则是铜器上生成的绿色物质，淘洗后使用。近来人们用醋处理铜使其生成绿色锈迹，收取后晒干备用。）
（凡是用赤铜屑，需用铁锅熔化后倒在瓦片上，滤去渣滓沉淀物，如此反复数次后收存使用。至于黑锡灰，是用铅沙制成；白锡灰不用于入药。）
（制作方法是：将铅打成钱币状，穿成串，放入瓦盆中，盛放生醋。将铅串横放在盆中，距离醋面三寸，再用瓦盆覆盖，放置在阴凉处，等待表面生出霜花，刷下收集，仍要盖好。）
（即黄丹，由单一的生铅经火煅研成细末，用水飞法处理。现在市售的黄丹多混杂有盐、硝石、砂石等杂质。凡是用黄丹，需用水漂洗去除硝盐和砂石，澄清干燥后，用微火炒至紫色，在地上放置以去除火毒，然后方可入药。）
（凡使朱砂，需捣细装入瓮埚中，用多层纸袋包裹，周围填入柳蛀木屑焙烧。其次用东流水浸泡至满，大火煮一个伏时（约24小时），去掉柳末和纸袋后取用。近来有人用煎银炉的底灰代替，这是错误的。炉底灰能腐蚀炼化一切丝织品，怎么可以服用呢？如果没有真品，不要使用。此处也涉及野狼毒的炮制说明。）
（只有周、秦、汉及五代时期出产的朱砂才可以使用。将其用火煅至微红，在醋中淬火六七次后使用。若用于点眼，需磨成粉；若用于散剂，需用胡桃研成粉配合使用。）
（这是铁上的红色锈衣，刮下来使用。）
（即朱砂，有好几种。硫砂如拳头大小，或重一镒，有十四个面，表面如镜子般光亮；如果遇到阴天或下雨，镜面上会有红色浆汁渗出。梅柏砂如梅子大小，夜间会发光，照亮整个房间。白庭砂如帝珠子大小，表面有小星闪烁。神座砂、金座砂、玉座砂，未经丹灶炼制而服用可延年益寿。其次还有辰锦砂、芙蓉砂、箭镞砂。以上九种都可以入药。丹砂入药只宜生用，切勿升炼。一经火炼，服用会致人死亡。研磨必须达到万遍，要轻如尘埃，并用磁石吸去铁气。朱砂恶磁石，畏盐水、车前草、石苇、皂荚、决明子、瞿麦、南星、乌头、地榆、桑椹、紫河车、地丁、马鞭草、地骨皮、阴地厥、白附子。忌食各种血类食物。）
(Chitongxie (Red Copper Scrap), which refers to the scrap falling off during copper hammering. Alternatively, red copper can be heated by fire and then quenched in water, causing the copper scraps to fall off naturally; these are washed clean with water. Good-quality yellow wine is added to a clay pot for stir-frying until sparks appear, at which point it is removed and ground into powder. It should be processed for two "Fu" periods (approximately 10 days) to remove earthiness, then ground as fine as powder. The standard ratio for processing is five liang of copper scrap to two yi of vinegar. Currently, people only calcine with fire and quench in vinegar seven times, grind finely, and use the water-floating method. One theory states that it must be stored for half a year after processing before being used in medicine; otherwise, it may cause death.)
(Both raw and refined copper develop a greenish-blue patina on their surface, which is considered the essence of copper. Large pieces are called Konglv (Empty Green), and those of secondary quality are called Kongqing (Empty Azure). Tongqing (Copper Green) refers to the green substance formed on copper vessels, which is washed and used. Recently, people have been treating copper with vinegar to generate green patina, collecting and sun-drying it for storage.)
(When using Chitongxie, melt it in an iron ladle, pour it onto tiles, filter out the dregs and sediment, and repeat this process several times before storing. Regarding Heixi Hui (Black Tin Ash), it is made from lead sand; Baixi Hui (White Tin Ash) is not used in medicine.)
(The preparation method involves shaping lead into coins, stringing them together, and placing them in a clay basin containing raw vinegar. The string of lead coins is placed horizontally in the basin, three cun above the vinegar level. The basin is covered with another clay tile and placed in a shady place until frost forms on the surface. The frost is brushed off and collected, ensuring it remains covered.)
(This is Huangdan (Lead Monoxide), produced by calcining pure lead, grinding it into a fine powder, and using the water-floating method. Commercially available Huangdan often contains impurities such as salt, saltpeter, and sand. To prepare it, wash with water to remove saltpeter and salt, clarify and dry, then stir-fry over low heat until it turns purple. Place it on the ground to dissipate fire toxicity before use in medicine.)
(When processing Zhusha (Cinnabar), crush it finely, place it in an earthenware crucible, cover it with a multi-layered paper bag, and bake it surrounded by worm-eaten willow wood shavings. Next, soak it in flowing eastern water until full, boil vigorously for one Fu period (approx. 24 hours), remove the willow shavings and paper bag, and use the residue. Recently, some have substituted the bottom ash from silver-smelting furnaces, which is incorrect. Furnace ash can corrode and refine all silk fabrics; how can it be ingested? If genuine material is unavailable, do not use. This section also mentions the processing of Yelangdu (Stemona Root).)
(Only Cinnabar from the Zhou, Qin, Han dynasties, and the Five Dynasties period is suitable for use. Calcine it until slightly red, quench in vinegar six or seven times, and then use. For ophthalmic use, grind into powder; for powder formulations, mix with walnut paste.)
(This is the red rust coating on iron, scraped off for use.)
(This is Zhusha (Cinnabar), which comes in several varieties. Liusha (Sulfur Cinnabar) is fist-sized or weighs one yi, has fourteen facets, and a mirror-like surface; on cloudy or rainy days, red liquid appears on its surface. Meibaisa (Plum Cypress Sand) is plum-seed sized and glows at night, illuminating a room. Baitingsa (White Court Sand) is emperor-bead sized with small star-like spots on its surface. Shenzuosa (Divine Seat Sand), Jinzuosa (Gold Seat Sand), and Yuzuosa (Jade Seat Sand) can prolong life when taken without alchemical refinement. Others include Chenjinsa (Chenjin Sand), Furongsasa (Hibiscus Sand), and Jianzusa (Arrowhead Sand). The above nine types are all suitable for medicinal use. When used medicinally, Zhusha should only be used raw; never calcine it. Once calcined by fire, ingestion causes death. Grinding must be done ten thousand times to achieve a fineness like light dust, and magnetic stones should be used to absorb iron impurities. Zhusha is incompatible with Cishi (Magnetite), fears Yan Shui (Salt Water), Cheqiancao (Plantain Herb), Shiwei (Pyrrosia Leaf), Zaojiao (Gleditsia Fruit), Juemingzi (Cassia Seed), Qumai (Dianthus Herb), Nanxing (Arisaema Rhizome), Wutou (Aconite Root), Diyu (Sanguisorba Root), Sangshen (Mulberry Fruit), Ziheche (Human Placenta), Diding (Scrophularia Root), Mabiancao (Verbena Herb), Digupi (Phellodendron Bark), Yindijue (Polygonatum Rhizome), and Baifuzi (Typhonii Rhizoma). Avoid consuming various blood products.)
