石钟乳
味甘，性温。无毒。产于始兴、江陵等地，多生长在岩洞之中。只有在阴暗潮湿的地方才能生长，是水滴汁液凝结而成，所以用“乳”来命名。形状像鹅的管子，中间是空的，又像蝉翼一样轻薄。颜色洁白干净且有光泽，（具备这种特征的无论厚薄都好。如果像枯骨死灰或者呈现黄、赤两种颜色，就不能使用。）长度在六七寸以上。采收没有固定时间，放入水中不会下沉。作为药用需要炼制，必须遵循雷公的方法。（每八两石钟乳，用甘草、紫背天葵各二两，用水煮一个时辰，捞出擦干，用慢火焙干，捣碎过筛，用水飞法处理，晒干后，再研磨一万遍备用。）如果操作不当，容易产生其他副作用。它忌讳的药物有三种：牡丹、玄石、牡蒙。畏惧紫石英，以蛇床子为引经药。主治咳嗽气逆上冲，治疗脚部软弱冷痛。能使五脏百节通畅，促进乳汁分泌，九窍通利。解除舌苔发黄、口渴多饮的症状，补益下焦虚损导致的遗精。益气壮阳，声音洪亮，明目。长期服用可以助孕，不经过炼制的会导致淋证。
（陈嘉谟）按语：朱丹溪说：石钟乳是性质刚烈猛烈的药剂。医经说：石类药物的药性刚烈。这话真是仁德啊！上天生育百姓靠谷物食物，等到生病用药来治疗。谷物的药性平和可以经常食用，药物的药性偏颇只能暂时使用，而石类药物则是偏颇得最厉害的。自古以来富贵人家，大多被方士迷惑。认为石类药物质地重、药气浓烈，服用可以延年益寿。习以为常成为风俗，遭受这种刚烈药气的祸害无法挽救，可悲啊！
代赭石
味苦、甘，性寒。另一种说法：味甘，性平。无毒。只产于代州（属于山西），多生长在山谷中。（还有一种说法：是代都城门下的红土。）颜色红得像鸡冠且有光泽，优质的甚至能染指甲而不褪色。如果难以得到真品，牡蛎可以代替。用火醋淬炼七次，然后研磨至极细，用水飞法处理。只能做成散剂调服，不要煎汤服用。畏惧雄黄和附子（天雄、附子），以干姜为引经药。入少阳三焦经，以及厥阴肝经。治疗妇女赤白带下、崩漏，以及难产胎盘不下；治疗小儿疳积、腹泻痢疾、惊风癫痫，以及尿血、遗尿不禁。驱除贼风蛊毒，杀灭鬼疰魅精。阳痿不起可以扶持，惊气入腹可以治愈。《圣济经》说：胆怯就是惊惧。胆怯则气浮，用重镇的药物来安定它。代赭石的沉重之性，用来镇压虚逆之气。孕妇忌服，恐怕导致堕胎。
Shi Zhong Ru (Stalactite)
Taste: Sweet. Temperature: Warm. Toxicity: Non-toxic. Origin: Produced in Shixing and Jiangling, mostly growing in rock caves. It only grows in dark and damp places, formed by dripping juice condensing, hence named "milk" (Ru). Shape resembles goose quills, hollow in the center, and light/thin like cicada wings. Color is pure white, clean, and lustrous. (Those with this quality are excellent regardless of thickness. If it resembles dead bones/ashes or shows yellow/red colors, it should not be used.) Length is over six to seven cun. Harvest time is indefinite; it does not sink in water. For medicinal use, it must be refined, strictly following Lei Gong's method. (For every 8 liang of Shi Zhong Ru, use 2 liang of Gancao [Licorice Root] and 2 liang of Zibei Tiankui [Basella rubra], boil in water for one fu shi [approx. 2 hours], remove, wipe dry, bake on slow fire, grind and sieve, process via water levigation [shui fei], sun-dry, then grind ten thousand times before storage/use]. If procedures are violated, adverse reactions may occur. Adverse interactions exist with three herbs: Mudan [Moutan Cortex], Xuan Shi, and Mu Meng. It is incompatible with Zi Shi Ying [Fluorite]; Snake Chu Zi [Cnidium Fruit] acts as its guide herb. Indications: Mainly treats cough with counterflow qi (ke ni shang qi), heals weak/cold pain in legs. Unblocks the five zang organs and hundred joints, promotes lactation, and benefits the nine orifices. Resolves tongue jaundice (she dan) and polydipsia, tonifies deficiency of the lower jiao causing spermatorrhea. Benefits qi, strengthens yin/yang, improves voice clarity, and brightens eyes. Long-term consumption aids fertility; unrefined usage causes lin syndrome (lin zheng).
(Chen Jiamo) Commentary: Zhu Danxi stated: "Shi Zhong Ru is a fierce/harsh agent." The Classics state: "The qi of stone drugs is fierce." How benevolent these words are! Heaven nourishes people with grain food, and uses medicine to treat illness. Grain qi is mild and can be consumed regularly; medicinal qi is biased and should only be used temporarily; stone drug qi is extremely biased. Since ancient times, wealthy families have often been misled by alchemists. Believing that stone drugs are heavy in substance and strong in qi, they consume them to prolong life. This habit became a custom, leading to incurable disasters from this harsh qi. Alas!
Dai Zhe Shi (Hematite)
Taste: Bitter, Sweet. Temperature: Cold. Alternative view: Taste sweet, temperature neutral. Toxicity: Non-toxic. Origin: Only produced in Daizhou (Shanxi Province), mostly growing in valleys. (Another theory: It is red soil from under the gates of the capital of Dai.) Color is red like a rooster's comb with luster; high-quality ones do not stain nails excessively. If genuine product is hard to obtain, Li Shi [Oyster Shell] can substitute. Process by quenching in vinegar over fire seven times, then grind to extreme fineness and process via water levigation. Only suitable for powder form (san); do not decoct for soup. Incompatible with Xiong Huang [Realgar] and Fu Zi [Aconite Lateralis Radix Preparata] (including Tian Xiong); Ganjiang [Zingiberis Rhizoma] acts as its guide herb. Enters Shaoyang Sanjiao Meridian and Jueyin Liver Meridian. Treats women's leukorrhea (chi wo), metrorrhagia/metrostaxis (beng lou), and difficult labor with retained placenta. Treats pediatric kan disease (malnutrition), diarrhea/dysentery, convulsions/epilepsy, hematuria, and enuresis/incontinence. Expels wind-torture and gu poison, kills ghost-infestation spirits. Supports impotence, cures fright qi entering the abdomen. *Shengji Jing* states: "Timidity is fright." Timidity causes floating qi; heavy agents settle it. The heaviness of Dai Zhe Shi settles deficient counterflow qi. Contraindicated in pregnancy due to risk of miscarriage.
