钟乳石：味甘，性温，有毒，归肺、肾二经。主治精气滑泄、寒性咳嗽，能壮补元气，增强性功能，安定五脏，疏通全身关节，通畅九窍，促进乳汁分泌，也能通利声音。以光泽润泽、质地轻松、颜色像经过提炼的硝石者为佳。长期研磨时不可中断，必须采用水飞法（加水研磨后取细粉）处理，以掺入臂上肌肉中看不见粉末为度。以蛇床子作为引药，忌与牡丹、玄石、牡蒙同用。畏紫石英和蓑草。忌食羊血。
按语：钟乳石性温，但形态有下行之意，适宜入肾经，肺为肾之母，故也并入肺经。各家本草记载其功效的很多，只有朱丹溪认为它是剽悍之剂，不宜轻易使用。不经过炼制就服用，会导致人患淋证。
雷公说：凡使用钟乳石，不要选用头部粗厚和尾部过大的，那是孔公石，不是真正的钟乳；也不要选用颜色发黑，以及经过大火烧过，或者长期在地上收藏的。曾经被其他药物炮制过的，也不得使用。必须选用色泽鲜明、薄而有光泽的，形状像鹭鸟羽毛管一样的为上品，长度有五到六寸的。
凡是修治的方法，先用五香水煮一个时辰（两小时），然后滤出。另外再用甘草、紫背天葵的汁液浸泡，再煮一个时辰。凡是八两钟乳石，要用沉香、零陵香、藿香、甘松、白茅各一两，先用水煮过一次。第三次才用甘草等三味药，各二两再煮，滤出擦干，用慢火焙干。然后放入臼中捣成粉末，过滤后再放入钵中，让有力气的年轻力壮者两三人不停地研磨，三天三夜不停歇，然后用清水飞研干净，用绢布筛过，在阳光下晒至干燥，再次放入钵中，研磨两万遍，最后用瓷盒收存备用。
矾石：味酸，性寒，无毒，归肺、肝二经。主治寒热往来、泄泻痢疾，白带过多、阴部蚀烂，各种恶疮癣疾，清利咽喉痹阻，消除眼部疼痛，祛除骨蒸潮热，禁止泄泻，收敛脱肛，配合皂荚可以涌吐风痰，配合蜂蜜、蜂蜡能消散痈肿。以光明如水晶者为佳。以甘草作为引药，忌与牡蛎同用，畏麻黄。
按语：矾石色白属西方金，适宜入肺家。味酸属东方木，适宜入肝部。肺肝功能正常，那么寒热等各种病症就可以无忧了。
雷公说：凡使用矾石，需要用磁瓶盛装，放在火中，使内外通红，用钳子揭开盖子，随即把石蜂窠放入赤红的瓶中，烧尽石蜂窠为止，用钳子夹出，放冷后敲碎放入钵中，研磨成粉。然后在屋檐下挖一个坑，深约五寸，用纸包裹矾粉留在坑中过夜，取出后再研磨。每修治十两矾石，用石蜂窠六两，烧尽为止。又说：凡使用要选光明如水晶，酸咸涩味俱全的，研磨成粉，装在干燥的磁瓶中。瓶子要能装两三升的。然后用六一泥涂抹在火旁，烤干，接着将白矾放入瓶内，用五方草、紫背天葵两种药材的自然汁各一镒，慢慢加入白矾在火中逼迫，使药汁变干，盖上瓶口，再用泥封住上下接口，用火一百斤。从巳时到未时，撤去火，取出白矾。瓶子取出放冷，敲碎取矾，凡是经过大火的，颜色像银子一样。自然伏火，重量不损失，擂细研磨如轻粉状，才可使用。
Zhongru Shi (Calcitum): Sweet in flavor, warm in nature, toxic. Enters the Lung and Kidney meridians. It primarily treats seminal emission due to cold and cold coughs; it strengthens Yuan Qi (Original Qi), enhances sexual function, calms the Five Zang organs, unblocks all joints, benefits the nine orifices, promotes lactation, and can also clear the voice. The best quality is lustrous, smooth, light in texture, and resembles refined saltpeter. When grinding for a long time, one must not stop; it must be processed by "water flying" (levigation). It should be applied to the arm muscle until no powder is visible. Snakebedzi (Cnidii Fructus) serves as its guiding herb. It is incompatible with Mudanpi (Moutan Cortex), Xuan Shi (Nigra Lapis), and Mumeng. It fears Zhi Yingshi (Fluorite) and Suo Cao. Avoid mutton blood.
Commentary: Zhongru Shi is warm in nature but has a descending tendency, making it suitable for entering the Kidney meridian. Since the Lung is the mother of the Kidney, it also enters the Lung meridian. Many materia medica texts describe its efficacy, but Zhu Danxi considered it a fierce agent that should not be used lightly. Consuming it without calcination causes Lin syndrome (dysuria).
Lei Gong said: When using Zhongru Shi, do not use those with thick heads or large tails, which are Konggong Shi (a different mineral); nor use those that are black in color, have been roasted over high fire, or have been stored on the ground for a long time. Those previously processed with other drugs must not be used. One must select pieces that are bright, thin, and lustrous, resembling egret feather tubes, preferably 5-6 cun in length.
The processing method is as follows: Boil in five-flavor herbal water for one Fu Shi (approx. 2 hours), then strain. Soak in the juice of Gancao (Licorice Root) and Zi Bei Tian Kui (Ophiopogon japonicus var. bulbifer) and boil again for one Fu Shi. For every 8 liang of Zhongru Shi, use Chenxiang (Aquilaria Wood), Linglingxiang (Lingzhi Fragrant Fruit), Huoxiang (Patchouli Herb), Gansong (Nardostachys Rhizome), and Baimao (Imperata Rhizome), each 1 liang. Boil once with water. In the third boiling, add Gancao and two other herbs (implied from context or standard practice, text says "Gancao etc. three flavors"), each 2 liang, boil again, strain, wipe dry, and bake over slow fire. Then pound into powder in a mortar, sieve, and place in a bowl. Have strong young men grind continuously for three days and nights without rest. Then purify by water flying, sieve through silk gauze, dry in the sun, return to the bowl, and grind 20,000 times. Store in a porcelain jar for use.
Fan Shi (Alumen): Sour in flavor, cold in nature, non-toxic. Enters the Lung and Liver meridians. It primarily treats alternating chills and fever, diarrhea and dysentery, leukorrhea (white discharge), genital ulcers, various malignant sores and tinea, clears throat bi-obstruction, relieves eye pain, removes bone-steaming heat, stops diarrhea, retracts prolapsed rectum, combined with Zao Jia (Ziziphus Spinosus Fruit) can induce vomiting for wind-phlegm, and combined with honey and beeswax can dissipate carbuncles and swellings. The best quality is bright like crystal. Gancao (Licorice Root) serves as its guiding herb. It is incompatible with Muli (Ostrea Concha) and fears Mahuang (Ephedrae Herba).
Commentary: Fan Shi is white, corresponding to the West and Metal element, thus suitable for entering the Lung organ. Its sour flavor corresponds to the East and Wood element, thus suitable for entering the Liver organ. When the Lung and Liver functions are regulated, various chills and fever symptoms can be alleviated.
Lei Gong said: When processing Fan Shi, store it in a porcelain bottle, heat it in fire until red inside and out. Use tongs to remove the lid, immediately insert stone bee combs into the red-hot bottle, burning the combs completely. Remove with tongs, let cool, crush, and grind into powder in a mortar. Dig a pit under the eaves, about 5 cun deep. Wrap the powder in paper and leave it in the pit overnight. Take it out and grind again. For every 10 liang of Fan Shi, use 6 liang of stone bee combs, burning them completely. Also, select pieces bright like crystal with complete sour, salty, and astringent tastes. Grind into powder and store in a dry porcelain bottle capable of holding 2-3 sheng. Apply Liu Yi Ni (Six-One Clay) around the fire side, dry it, then place Bai Fan (White Alum) inside. Add natural juices of Wu Fang Cao and Zi Bei Tian Kui, each 1 yi. Slowly add Bai Fan to the fire to drive off moisture until the liquid dries. Cover the bottle mouth, seal top and bottom with clay, and burn with 100 jin of firewood. From Si hour to Wei hour, remove the fire and take out the Bai Fan. Let the bottle cool, crush, and retrieve the alum. After high-fire processing, it turns silver-colored. This natural fixation ensures no weight loss. Grind finely like Qing Fen (Calomel) before use.
