滑石，生长于赭阳的山谷以及泰山的北坡，或者掖县的北部白山，或者卷山，如今道州、永州、莱州、濠州都有出产。这种药材有两种：道州和永州出产的，颜色白滑如同凝固的油脂。《南越志》记载：“城县出产一种石，这种石就是滑石。”当地百姓将其用来制作烧制器皿的工具，用来烹煮鱼等食物。莱州和濠州出产的，纹理粗糙质地呈青色，带有黑白斑点，也称之为斑石。这两种都可以用来制作器皿，非常精美好用。刚开采出来时软烂如泥，时间久了逐渐变得坚硬，当地人都在矿穴中趁着它柔软的时候进行制作，花费的力气很少，否则如果变硬了就会耗费很多功夫。《神农本草经》（简称《本经》）所载的产地都是北方，而现今医家所使用的，多是白色的，是从南方运来的。另外查阅雷敩的《炮炙方》，滑石有五种颜色，应当使用像方解石那样白色的。绿色的那种，性寒有毒，不入药。书中又说：“凡是滑石像冰一样白或带青色，画在石头上有白色细腻纹路的，才是真品。”按照这种说法，则与现在从南方运来的又都相似，使用它就没有疑问了。然而雷敩虽然号称是隋代人，但看他的书里却有提到唐代以后的药名，或许是后人增删修改过的吧。有人说沂州出产一种白色的滑石，非常好，与《本经》所说的泰山北坡相符合。但是当地人不把它作为药材采集，所以医生们也很少知道使用它。现在濠州医生所供应的青色滑石，声称性微寒无毒，主治心气涩滞。这与《本经》的记载大同小异。另外吴录的《地理志》及《大康地记》记载：“郁林州布山县，有很多毒蛇，它们的毒性能杀人，有一种冷石可以解毒，石头颜色赤黑，味道苦，磨成粉末敷在疮口中，并让人咬紧牙关立刻苏醒，又名切齿石。”现在的人多用冷石磨成粉，治疗痱子疮，有人说这就是滑石，只是味道甘苦不同罢了。仔细考证古方中利用滑石利小便、治疗淋证涩痛，多单独使用滑石。又或与石苇一同捣碎成末，用水冲服刀圭量（古代计量单位），效果更快。另外滑石还主治石淋引起的烦闷，取滑石十二分，研成粉末，分两次服用，用水调和搅匀使其散开，一次性服下。烦热症状停止后，就停止后续服药；如果症状未完全消除，全部服完必定痊愈。

Huashi (Talcum), grows in the valleys of Zheyang and on the north slopes of Mount Tai, or in Baishan to the north of Ye County, or in Juanshan. Currently, it is produced in Daozhou, Yongzhou, Laizhou, and Haozhou. There are two types: those from Daozhou and Yongzhou are white and smooth like congealed fat. *Nanyue Zhi* (Records of Southern Yue) states: "Cheng County produces a type of stone; this stone is Huashi (Talcum). Locals use it as a tool for firing vessels, used for cooking fish." Those from Laizhou and Haozhou have coarse texture and green quality, with black and white spots, also called Banshi (Spotted Stone). Both types can be used to make vessels and are very exquisite. Initially soft and rotten like mud when first extracted, they gradually become hard over time. People there manufacture them while still soft in the mines, requiring little effort; otherwise, if hard, it would consume much labor. The land sources recorded in *Benjing* (*Shennong Bencao Jing*, Divine Farmer's Materia Medica) are all in the north, whereas those currently used by physicians are mostly white and come from the south. Furthermore, according to Lei Xiao's *Paozhi Fang* (Prescriptions for Processing Drugs), Huashi (Talcum) has five colors; one should use the white kind resembling Fangjieshi (Calcite). The green kind is cold in nature and toxic, and is not used in medicine. It further states: "Any Huashi (Talcum) that is white like ice or bluish-white, with fine white patterns when drawn on stone, is genuine." According to this description, it resembles those coming from the south now, so there is no doubt in using it. However, although Lei Xiao is named as a Sui dynasty person, his book mentions drug names from after the Tang dynasty, suggesting perhaps later additions or modifications. Some say Yizhou produces a type of white Huashi (Talcum) which is excellent, matching the description of the north slopes of Mount Tai in *Benjing*. However, locals do not harvest it as medicine, so physicians rarely know to use it. The Qinghuashi (Green Talcum) supplied by physicians in Haozhou today claims to be slightly cold in nature and non-toxic, mainly treating stagnation of Heart Qi. This is largely similar to *Benjing*. Additionally, *Wu Lu Di Li Zhi* (Geographical Records of Wu) and *Da Kang Di Ji* (Records of Da Kang) state: "Bushan County in Yulin Prefecture has many venomous snakes whose poison kills humans; there is a Cold Stone that can detoxify them. The stone is reddish-black in color and bitter in taste. Ground into powder and applied to wounds, along with biting teeth tightly, leads to immediate recovery. It is also called Qieshi Shi (Tooth-Biting Stone)." Nowadays, people often use Cold Stone ground into powder to treat miliaria (heat rash) or sores. Some say it is Huashi (Talcum), differing only in sweet versus bitter taste. Careful examination of ancient formulas shows that Huashi (Talcum) is often used alone to promote urination and treat strangury with difficulty. When mixed with Shiwei (Andromeda Leaf) and pounded into powder, taken orally with water in the amount of a Dao Gui (ancient measurement), the effect is faster. Furthermore, it treats restlessness and oppression caused by Shilin (Stone Strangury). Take twelve parts of Huashi (Talcum), grind into powder, divide into two doses, mix with water and stir until dispersed, and take at once. Once the feverish heat subsides, stop subsequent doses; if symptoms persist, finishing the dose will surely lead to recovery.
