特生 石，文具 石条下。
石（特生石），生长在汉中中山谷以及少室山，现在潞州也有出产。药性大热，放入水中能使水不结冰，质地坚硬且抗拒火焰，焚烧一整天一夜，只是松散解体而不会失去其坚硬的本质。市场上的人多取洁白的石头来冒充它，烧后就会变成灰烬。这种药物对于攻逐积聚和顽固寒冷之病效果良好。使用时必须用真品才好。
又有特生石，生长在西域。张华在《博物志》中说：鹳鸟在孵卵时，会取这种石头围绕在蛋的周围，用来辅助暖气。方术之士使用它，以从鹳巢中取得的为真品，就是这种特生石。然而这种颜色的石头很难得，人们多用汉中的石头代替，外形呈紫红色，内部洁白如霜，中间有凹陷像臼一样，形状像牙齿，石块比白石小，但肌理颗粒大几倍，就像小豆那么大。白石的颗粒细小，仅仅像粟米大小。
又有握雪石，出产于徐州西宋里山，深入地下丈余，生长在腐烂土石之间，颜色洁白、细腻柔软像面粉一样。
又见下条提到的苍石，生长在西域。苏恭说：特生石，又名苍石。而梁州的特生石，也有青色的。房陵、汉川与白石同处，也有青色的，大多与特生石相似，只是不入药方使用。现在的医生大多只用特生石，也就是白石。形状类别相近，因此更应该仔细选择。古方治疗寒冷积聚，都用特生石。胡洽的大露宿丸，主治寒冷百病的方子：特生石（炼过）、干姜、桂心、皂荚、桔梗各三两，附子二两，将六味药捣碎筛粉，用蜜制成丸药，每次服用梧桐子大小的五丸，每日三次，逐渐增加剂量，以见效为限度。又有匈奴露宿丸、硫黄丸，都主治积聚，以及饮食不下、心腹坚实，都用特生石。近代却很少使用了。
特生石，文字详见于石条之下。
Shi (Tesheng Shi), grows in the Zhongshan valleys of Hanzhong and Mount Shaoshi; it is also found now in Luzhou. Its nature is intensely hot; when placed in water, it prevents the water from freezing. It is hard and fire-resistant; even after burning for a day and night, it merely crumbles without losing its hardness. People in the market often use pure white stones to pass them off as this drug, but these turn to ash when burned. This medicine is excellent for attacking accumulations and chronic cold conditions. It must be genuine to be effective.
There is also Tesheng Shi, which grows in the Western Regions. Zhang Hua's *Bowuzhi* states: "When storks incubate eggs, they take [this] stone to surround the eggs, to assist warmth." Practitioners of alchemy and magic arts use it, considering those taken from stork nests to be genuine; this is the Tesheng Shi. However, this color is rare, so people often substitute stones from Hanzhong. These have a purple-red exterior and an interior white as frost, with a central depression like a mortar, shaped like teeth. The lumps are smaller than Baishi, but their texture grains are several times larger, about the size of small beans. Baishi grains are fine, only the size of millet.
There is also Xuexue Shi, produced at Xisongli Mountain in Xuzhou. It grows more than one zhang underground, amidst rotting earth and stones. Its color is white, fine, and soft like flour.
Also mentioned in the following entry is Cangshi, which grows in the Western Regions. Su Gong says: "Tesheng Shi is also named Cangshi." The Tesheng Shi from Liangzhou also has a green variety. In Fangling and Hanchuan, where Baishi is found, there are also green varieties. These are mostly similar to Tesheng Shi but are not used in prescriptions. Modern physicians mostly use only Tesheng Shi, which is Baishi. Since their shapes are similar, careful selection is particularly advisable. Ancient formulas for treating cold accumulations all used Tesheng Shi. Hu Qia's Da Lusu Wan, a formula for treating various diseases caused by cold, consists of: refined Tesheng Shi, Ganjiang, Guixin, Zaojiao, Jiegeng, each 3 liang, and Fuzi 2 liang. The six ingredients are pounded and sifted, made into pills with honey. Take five pills the size of wutong seeds three times a day, gradually increasing the dose until the desired effect is achieved. There are also Xiongnu Lusu Wan and Liuhuang Wan, both treating accumulations, inability to eat or drink, and firmness of the heart and abdomen, all using Tesheng Shi. In recent times, however, it is rarely used.
Tesheng Shi: See the entry under Shi for details.
