井泉石
气性大寒，无毒。各地都有生长，（饶阳郡出产的质量最好。）生长在田野土地之中。需要挖掘一丈多深才能采到。形状像土黄，有方、圆、长、短各种形态，大小不一；内部质地坚实，外部却呈层状，层层重叠交错。采收没有固定时间，但必须研磨得极其细碎。如果不这样处理，会导致人患淋证（以小便频数短涩、滴沥刺痛为主症的疾病）。它是解除心脏热结的最佳药物，停止肺经热咳也非常奇妙。配合大黄和栀子，可以治疗眼睑突然暴发的肿胀；配合决明子和菊花，可以治疗眼疳疾突然生成的翳膜。主要统领治疗各种热证，没有其他特殊功效。
花蕊石
质地极大且坚硬沉重，出自陕州。颜色类似硫黄，黄色中间带有白点。因此得名“花蕊”，最难求得真品。得到后研磨成粉霜，治疗各种出血证有神奇疗效。男子用童便搀半量酒调和服用，女子用童便搀半量醋调服。多服后身体就会疏通，瘀血逐渐化为黄水。这确实是猛烈的药物，果然是见效快的方剂。金创（金属利器造成的创伤）流血，敷上伤口就能愈合。产后血晕，舔舐药末立刻安宁。
青礞石
颜色微绿，出自山东。想要辨别真假，必须依法炮制。敲碎成小颗粒，储存在银罐中。加入一半焰硝，（石头二两，硝二两。）用盐泥密封加固。用武火煅烧一炷香的时间，取出时颜色如同雌黄。变得软脆容易研磨，才是真品。制成粉末用水飞法研细，入药做成散剂或丸剂。力量能坠下痰浊，滚痰丸必定使用；功效也能消食，积食方中常加用。不仅是医生给小儿治病，也治疗男女疾病。
滑石
味道甘，气性大寒。性质沉重，主降，属阴。无毒。各地多有出产，采收没有固定时间。细腻洁白的是佳品，粗顽青黑的不宜使用。研磨细后用“水飞”法净化，服用后才能起到滑利通畅的作用。畏恶曾青，适宜配伍甘草。以石韦为引经药，归入足太阳膀胱经。通利九窍，津液频繁生成，运行六腑积滞而不受阻。驱逐凝血而解除烦渴，分利水道以充实大肠。消除食毒补益脾气，泄降上逆之气降低火势。因为这种滑利的特性，所以加上“滑”字命名。堕胎效果如神，孕妇忌服。
（陈嘉谟）按语：滑石治疗口渴，并不是真正能直接止渴。而是凭借它通利窍道的功能，渗利去除湿热，使得脾气恢复中和状态，那么口渴自然停止。假如天时湿气淫溢太过，人患小便不利且口渴，正适宜用此药来渗泄湿气，口渴自然不再产生。如果没有湿邪，小便自利而口渴的，就知道体内有燥热，燥热适宜滋润，如果误用服用，这是更加耗亡津液，而口渴反而加重了。难道不是违反禁忌吗！
Jingquanshi (Well Spring Stone)
The nature is greatly cold, and it is non-toxic. It grows everywhere in the vicinity, (those from Raoyang Commandery are superior.) It is found only within field lands. One must dig about a zhang (approx. 3.3 meters) deep to obtain it. Its shape resembles Tuhuang (Earth Yellow), varying in square, round, long, and short forms, with unequal sizes; internally it is solid and firm, while externally it is layered, overlapping and interlacing. There is no fixed time for harvesting, but it must be ground extremely fine. If not done so, it may cause patients to suffer from Lin syndrome (a disease characterized by frequent, scanty, and painful urination). It is best for resolving heat accumulation in the Heart, and also excellent for stopping heat coughs in the Lung meridian. Combined with Dahuang (Rhubarb Root and Rhizome) and Zhizi (Gardenia Fruit), it treats sudden swelling and edema of the eyelids; combined with Juemingzi (Cassia Seed) and Juhua (Chrysanthemum Flower), it treats eye malnutrition diseases (Yan Gan) where pterygium or corneal opacity suddenly appears. It generally governs various heat conditions, having no other special capabilities.
Huaruishi (Flower Stamen Stone)
It is extremely large, hard, and heavy, originating from Shanzhou. Its color resembles Liuhuang (Sulfur), yellow with white spots in between. Hence named Huaruishi, it is hardest to obtain as genuine. After obtaining it, grind it into powder frost; it is miraculous for treating various blood disorders. For men, mix half with Tongbian (Child's Urine) and half with wine; for women, mix half with Tongbian and half with vinegar. Taking more will make the body unobstructed, and stasis blood will gradually transform into yellow fluid. Indeed, it is a drastic medicine, truly a rapid prescription. For Jinchuang (metal weapon wounds) with bleeding, applying it causes the wound to close. For postpartum blood fainting, licking the powder brings immediate peace.
Qingmengshi (Green Meng Stone)
Its color is slightly green, originating from Shandong. To distinguish fake from real, one must process it according to method. Crush it into small granules, store them in a silver jar. Add half Yanxiao (Calcined Mirabilite), (two liang of stone, two liang of salt). Seal firmly with Yanni (Salt Mud). Roast over vigorous fire for the duration of one incense stick. Take out when the color resembles Cihuang (Realgar). It should become soft and brittle, easy to pound, to confirm it is genuine. Grind into powder using the water-flying method, enter medicine as powder or pill. Its power can drop phlegm, thus it is essential in Gutan Wan (Rolling Phlegm Pill); its function also aids digestion, thus it is often added to Jishi Fang (Food Accumulation Formulas). Not only do doctors use it for children, it also treats male and female ailments.
Huashi (Talcum)
The taste is sweet, the nature is greatly cold. Its property is heavy, descending, and yin. It is non-toxic. It is abundant everywhere, with no fixed harvesting time. Fine, pure white pieces are superior; coarse, stubborn, dark green-black pieces should not be used. Grind finely and purify using the water-flying method; only then does it provide smooth and unobstructed effects when taken. It is adverse to Zengqing (Azurite), and suitable to be paired with Gancao (Licorice Root). Shiwei (Pyrrosia Leaf) acts as its guide drug, entering the Foot-Taiyang Bladder Meridian. It benefits the nine orifices, causing fluids to generate frequently; it moves stagnation in the six fu organs without obstruction. It expels coagulated blood and resolves thirst and vexation; it separates water pathways to fill the Large Intestine. It eliminates food toxicity and tonifies Spleen qi, drains upward-rebellious qi and descends fire. Because of this slippery nature, the name "Slippery" (Hua) is added. It induces abortion like a divine effect; pregnant women should avoid taking it.
(Mo) Commentary: Huashi treats thirst, not because it directly stops thirst. Rather, relying on its ability to benefit orifices and seep out damp-heat, the Spleen qi returns to harmony, and thirst naturally ceases. If the heavenly climate has excessive dampness invading, and a person suffers from difficult urination accompanied by thirst, it is exactly appropriate to use this herb to seep and drain, and thirst will naturally not arise. If there is no dampness, and urination is free yet thirst exists, one knows there is internal dryness-heat. Dryness requires moistening; if mistakenly used, this would further deplete body fluids, and thirst would instead intensify. Would this not be violating the contraindications!
