味甘，寒、大寒，无毒。主治身热，泄 ，女子乳难，癃闭，利小便，荡胃中积聚寒热，
益精气，通九窍六腑津液，去留结，止渴，令人利中。久服轻身，耐饥，长年。一名液石，
一名共石，一名脱石，一名 石。生赭阳山谷，及太山之阴，或掖北白山，或卷山，采无时。
（石苇为之使，恶曾青。）
滑石色正白，《仙经》用之以为泥。又有冷石，小青黄，性并冷利，亦能熨油污衣物。
今出湘州、始安郡诸处。初取软如泥，久渐坚强，人多以作冢中明器物，并散热人用之，不
正入方药。赭阳县先属南阳，汉哀帝置，明《本经》所注郡县，必是后汉时也。掖县属青州
东莱，卷县属司州荣阳。（《新修》二三页，《大观》卷三，《政和》八八页）
味甘、辛，温，无毒。主治心腹咳逆邪气，补不足；女子风寒在子宫，绝孕十年无子；
治上气心腹痛，寒热邪气结气，补心气不足；定惊悸，安魂魄，填下焦，止消渴，除胃中久
寒，散痈肿，令人悦泽。久服温中，轻身延年。生太山山谷。采无时。（长石为之使，得茯
苓、人参、芍药共治心中结气；得天雄、菖蒲共治霍乱。畏扁青、附子，不欲 甲、黄连、
麦句姜。）
今第一用太山石，色重澈，下有根。次出雹零山，亦好。又有南城石，无根。又有青绵
石，色亦重黑，不明澈。又有林邑石，腹里必有一物如眼。吴兴石四面才有紫色，无光泽。
会稽诸暨石，形色如石榴子。先时并杂用，今丸散家采择，惟太山最胜，余处者，可作丸酒
饵。《仙经》不正用，而为世方所重也。（《新修》二五页，《大观》卷三，《政和》九二页）
【滑石】
味甘，性寒至大寒，无毒。主治身体发热、腹泻、女子乳汁不通、小便淋漓不畅或闭塞，能通利小便，清除胃中积聚的寒热邪气，补益精气，疏通九窍及六腑的津液运行，去除体内停留的结滞，缓解口渴，使人感觉体内通畅。长期服用可使人身体轻健，耐饥抗饿，延年益寿。又名液石、共石、脱石、 石。产于赭阳山谷，以及泰山的北坡，或者掖县北面的白山，或者卷山，采集没有固定时间。（石苇为其引经药/增效药，忌与曾青同用。）
滑石颜色正白，《仙经》用它来制作泥料。又有冷石，颜色小青黄，性质也都寒冷滑利，也能用来熨烫油污衣物。现在出产于湘州、始安郡等地。刚开采时软如泥，时间久了逐渐变坚硬，人们多将其用作墓中的照明器物，并作为散热用途使用，并不正规地进入方剂药物中。赭阳县先前属于南阳郡，汉哀帝时设置，明《神农本草经》所注释的郡县名称，必定是后汉时期的情况。掖县属于青州东莱郡，卷县属于司州荥阳郡。（出自《新修本草》第二十三页，《大观本草》卷三，《政和本草》第八十八页）
【紫石英】
味甘、辛，性温，无毒。主治心腹部的咳嗽气逆及邪气，补益不足；治疗女子因风寒侵袭子宫导致的十年不孕；治疗上气、心腹痛、寒热邪气及气机郁结，补益心气不足；安定惊悸，安宁魂魄，填补下焦，止住消渴，去除胃中久留的寒气，消散痈肿，使人面色红润光泽。长期服用可温暖中焦，身体轻健，延年益寿。产于泰山山谷。采集没有固定时间。（长石为其引经药/增效药，与茯苓、人参、芍药同用可共同治疗心中气结；与天雄、菖蒲同用可共同治疗霍乱。畏忌扁青、附子，不喜欢与 甲、黄连、麦句姜同用。）
现在最常用的是泰山石，颜色深沉通透，下面有根。其次出产自雹零山，也很好。又有南城石，没有根。又有青绵石，颜色也深黑，但不通透。又有林邑石，腹部里面必有一个像眼睛一样的东西。吴兴石四面仅有紫色，没有光泽。会稽诸暨石，形状颜色像石榴籽。以前都混杂使用，现在制作丸散的药物家进行挑选，只有泰山石最好，其他产地的，可以用来制作丸剂、酒剂或饵剂。《仙经》不正规使用它，但它被世俗方书所重视。（出自《新修本草》第二十五页，《大观本草》卷三，《政和本草》第九十二页）
[Shihuo (Talcum)]
The flavor is sweet, the nature is cold to great cold, and it is non-toxic. It primarily treats body heat, diarrhea, difficulty in lactation for women, strangury or urinary retention, promotes urination, sweeps away accumulated cold and heat pathogens in the stomach, benefits essence and qi, unblocks the fluids of the nine orifices and six fu organs, removes lingering stagnation, relieves thirst, and makes the interior feel clear and open. Long-term use lightens the body, increases resistance to hunger, and prolongs life. It is also known as Yeshi (Liquid Stone), Gongshi, Tuoshi, and [missing character]shi. It grows in the valleys of Zheyang, on the northern slopes of Mount Tai, or in Baishan north of Yexian, or in Juan Mountain. It can be harvested at any time. (Shiwei [Pyrrhosiae Herba] acts as its guiding/enhancing herb; it is incompatible with Cengqing [Azurite].)
Shihuo is pure white in color. The *Xianjing* (Immortal's Classic) uses it to make mud/paste. There is also Lengshi (Cold Stone), which is small greenish-yellow; its nature is also cold and slippery, and it can also be used to iron oily clothes. Currently, it is produced in Xiangzhou, Shian Commandery, and other places. When first extracted, it is soft like mud, but over time it gradually becomes hard. People often use it as lighting vessels in tombs and for dissipating heat, but it is not formally included in prescriptions. Zheyang County previously belonged to Nanyang Commandery and was established during the reign of Emperor Ai of Han. The commanderies and counties annotated in the *Benjing* (*Shennong Bencao Jing*) must reflect the situation of the Later Han dynasty. Yexian belongs to Donglai Commandery, Qingzhou; Juan County belongs to Rongyang, Sizhou. (From *Xinxiu Bencao* p.23, *Daguan Bencao* Vol.3, *Zhenghe Bencao* p.88)
[Zhiyingshi (Fluorite)]
The flavors are sweet and pungent, the nature is warm, and it is non-toxic. It primarily treats cough and rebellious qi in the heart and abdomen caused by pathogenic factors, and tonifies deficiencies; it treats infertility for ten years in women due to wind-cold invading the uterus; it treats upper rebellious qi, heart and abdominal pain, cold-heat pathogenic factors, and stagnant qi; it tonifies deficiency of heart qi; it calms palpitations and fright, stabilizes the soul and hun, fills the lower jiao, stops xiaoke (wasting-thirst syndrome), eliminates long-standing cold in the stomach, disperses carbuncles and swellings, and gives the person a lustrous complexion. Long-term use warms the middle jiao, lightens the body, and prolongs life. It grows in the valleys of Mount Tai. It can be harvested at any time. (Changshi acts as its guiding/enhancing herb; when combined with Fuling [Poria], Renshen [Ginseng Radix], and Shaoyao [Peony Root], it jointly treats stagnant qi in the heart; when combined with Tianxiong [Aconiti Lateralis Radix Preparata] and Changpu [Acori Tatarinowii Rhizoma], it jointly treats Huoluan [cholera-like disorder]. It fears Bianqing [Magnetitum] and Fuzi [Aconiti Lateralis Radix Preparata]; it does not desire to be combined with [missing character]jia, Huanglian [Coptidis Rhizoma], and Maijujiang [possibly a specific mineral or herb].)
Currently, the best grade is from Mount Tai, which is deep-colored and translucent, with roots underneath. The next best comes from Baoling Mountain, which is also good. There is also Nancheng stone, which has no roots. There is also Qingmian stone, which is dark black but not translucent. There is also Linyi stone, which necessarily has an object inside resembling an eye. Wuxing stone has only purple color on all four sides and lacks luster. Kuaiji Zhuji stone resembles pomegranate seeds in shape and color. Previously, they were all used indiscriminately. Now, manufacturers of pills and powders select them, considering only the stone from Mount Tai to be superior. Those from other places can be used to make pills, wine infusions, or pastes. The *Xianjing* does not formally use it, but it is valued by secular prescriptions. (From *Xinxiu Bencao* p.25, *Daguan Bencao* Vol.3, *Zhenghe Bencao* p.92)
