【云母】
凡是颜色黄黑、质地浓厚坚硬，或者经过妇女手把玩过的赤色云母，都不中用。必须选用光洁莹润、色泽如冰的云母作为上品。
每次修治一斤云母，先用小地胆草、紫背天葵、生目草地、地黄汁各一镒（注：重量单位）。如果是干药则细切，如果是湿药则取汁。将这些药放入瓷锅中，将云母置于诸药之下，加入天池水三镒，点火煮制。煮一天一夜，水火不要失控。这样云母自然会变成碧玉状的浆液沉在锅底。此时再猛投天池水进去，搅动物体，如果浮起像锅巴涎沫一样的东西就去除掉。如此淘洗三次，洗净后取出。取沉香一两，捣成末，用天池水煎煮沉香汤三升，以此分为三次再次淘洗云母浆。最后在日中晒干，即可使用。泽泻是它的引经药。它厌恶徐长卿和羊血；畏惧甲矾石、东流水、百草上的露水、茅屋的漏水；能制约汞；被丹砂所伏。
【石钟乳】
凡是修治时，不要使用头部粗厚且尾部巨大的“孔公石”；不要使用颜色发黑、经过大火惊吓过（指煅烧不当）、长期在地上收藏的、曾经被药物制过的石钟乳，这些都不能用。必须选用鲜明、薄而有光润、形状像鹅翎筒子的为上品，长度在五到六寸左右。
修治方法：先用五香水煮过一个时辰（两小时），然后捞出。另外再用甘草、紫背天葵汁浸泡，再煮一个时辰。八两钟乳，用沉香、零陵香、藿香、甘松、白茅根等各一两，先用水煮过一次；第二次才用甘草等二味药各二两再煮。煮好后捞出，擦干，用慢火烘干。然后放入臼中杵碎如粉，筛过后放入钵中，让有力气的年轻壮汉两人不停研磨三天三夜，不要停歇。然后用清水飞澄沉淀，用绢布过滤，在日中晒干。再次放入钵中研磨两万遍，最后用瓷盒收贮备用。蛇床子是它的引经药。它厌恶牡丹、玄石、牡蒙、人参、白术、苍术；忌食羊血；畏惧紫石英、蓑草、韭实、独蒜、胡葱、胡荽、麦门冬、猫儿眼草。
[Cloud Mother (Yunmu)]
Any Cloud Mother that is yellowish-black, thick and hard, or red in color having been handled by women's hands, is useless. One must select those that are lustrous, translucent, and ice-white as the superior grade.
For processing one *jin* of Cloud Mother, first take one *yi* each of *Xiaodichangcao* (Herba Oldenlandiae Diffusae), *Zibeitiankui* (Folium Basellae Rubrae), *Shengmucadi* (likely a local variant or specific preparation), and fresh juice of *Dihuang* (Radix Rehmanniae Preparata). If the herbs are dry, cut them finely; if wet, extract their juice. Place these medicines in a porcelain crucible, put the Cloud Mother beneath the medicines, add three *yi* of Tianchi water, and boil over fire for one day and one night. Do not let the fire and water conditions go out of control. The Cloud Mother will naturally turn into a jasper-green slurry settling at the bottom of the pot. At this point, vigorously pour in more Tianchi water and stir the mixture. Remove any floating substances resembling scum from the pot walls. Repeat this washing process three times until clean. Take out the material. Grind one *liang* of Chenxiang (Lignum Aquilariae Resinatum) into powder, decoct it in three *sheng* of Tianchi water to make a Chenxiang decoction, divide it into three parts, and use each part to wash the Cloud Mother slurry again. Finally, dry it under the sun for use. *Zexie* (Rhizoma Alismatis) acts as its guiding herb. It is incompatible with Xuchangqing (Herba Cynanchi Paniculati) and sheep blood; it fears Jia Fanshi (Alumen), flowing water from the east, dew on hundred herbs, and leaky water from thatched roofs; it can control Hong (Mercurius); and it is subdued by Dansha (Cinnabaris).
[Stalactite (Shizhongru)]
When processing, do not use "Konggong Shi" which has a thick head and large tail; do not use Stalactite that is black in color, has been subjected to intense fire (improper calcination), stored on the ground for a long time, or previously processed with other drugs. One must select those that are bright, thin, lustrous, and shaped like goose quill tubes, with a length of five to six cun, as the superior grade.
Processing method: First, boil in Wuxiang water for one shichen (two hours), then drain. Separately, soak in a mixture of Gancao (Radix Glycyrrhizae) and Zibeitiankui juice, and boil again for one shichen. For eight *liang* of Zhongru, use one *liang* each of Chenxiang (Lignum Aquilariae Resinatum), Linglingxiang (Flos Agastachis), Huoxiang (Herba Pogostemonis), Gansong (Radix Nardostachyos), and Baimaogen (Rhizoma Imperatae). Decoct once with water. For the second decoction, use two *liang* each of Gancao and another unspecified herb (context implies the remaining ingredients or a specific pair, text says "Gancao etc. two flavors"), boil again, drain, wipe dry, and slowly bake over mild fire. Then pound in a mortar until powdered, sieve, and place in a bowl. Have two strong young men grind continuously for three days and nights without rest. Then perform water levigation (flying with water), filter through silk gauze, and dry under the sun. Grind again in the bowl twenty thousand times. Finally, store in a porcelain box for use. Shechuangzi (Fructus Cnidii) acts as its guiding herb. It is incompatible with Mudan (Cortex Moutan), Xuanshi (Lapis Ferri Oxidi), Mumeng (likely a mineral drug), Renshen (Radix Ginseng), Baizhu (Rhizoma Atractylodis Macrocephalae), Cangzhu (Rhizoma Atractylodis), and mutton blood; it fears Zi Shiying (Mica Rubra), Suocao (likely a grass), Jiushi (Semen Allii Tuberosi), Dusan (Bulbus Allii Sativi), Hucong (Bulbus Allii Fistulosi), Huisui (Herba Coriandri Sativi), Maidong (Radix Ophiopogonis), and Mao'er Yancao (likely a specific herb).
[Alum (Fanshi)]
Used raw to detoxify; used processed to promote tissue regeneration. Gancao (Radix Glycyrrhizae) acts as its guiding herb. It is incompatible with Musli (Concha Ostreae); it fears Mahuang (Herba Ephedrae) and Hongxinhui (Red Heart Ash).
