也。
味甘，性温，无毒。主治风寒引起的虚损，腰脚疼痛麻木，安定五脏，补益元气。又名石饴饼。产于名山土石之中，采集没有固定时间。
这种石头也是钟乳石的一类，形状像曾青但带有白色和黑色斑纹，质地软脆容易破碎，现在茅山东西两侧及西平山都有出产，凿开泥土即可取得。民间方剂中不见使用，《仙经》中有刘君导仙散用到它。另外《真诰》记载：李整采集服用，治疗风痹虚损，从而得以长寿。
【考证】隋朝时有位化公，所服用的也叫石脑，产自徐州宗里山，最初在烂石中，深入地下丈以下才能找到，大小如鸡蛋或枣子，一触碰就散开像面粉一样，呈黄白色，当地人称为“握雪石”，说服用它可以长生。这与李整的情况相吻合。
味酸，性温，大热，有毒。主治妇女阴部腐蚀溃烂，疽疮痔疮，恶血，坚固筋骨，治疗头部脱发。治疗心腹部的积聚邪气、胁肋处的冷癖，咳嗽气逆，脚部寒冷疼痛软弱无力，以及鼻出血，恶疮，下部湿疮，止血，杀灭疥虫。能够熔化金银铜铁等奇异物质。产于东海牧羊山谷中，以及泰山、河西山，是矾石的液体产物。
东海郡隶属于北徐州，而箕山也有出产。现在第一种出自扶南林邑，颜色像鹅蛋刚出壳时那样，名叫昆仑黄。其次出自外国，从蜀地来，颜色深且光亮。民间方剂用它治疗脚弱及顽固性寒冷非常有效。《仙经》中也颇有用到它。所谓能熔化的奇异物质，都是《黄白术》及炼丹合丹的方法。这里说是矾石液，现在南方没有矾石，恐怕未必如此。
味咸，微温，无毒。主治崩中漏下（子宫出血），破除子宫内的瘀血，症瘕结气，寒热往来，腹痛，不孕，阴痿阳痿不合，补充不足。治疗男子阴茎头寒冷，阴部潮湿瘙痒，去除臭汗，消除水肿。长期服用不感到饥饿，使人有子嗣。又名白石，又名石生，又名羊起石，是云母的根部。产于齐山山谷及琅玡云山、阳起山，采集没有固定时间。桑螵蛸作为它的引药，忌与泽泻、菌桂、雷丸、蛇脱皮同用，畏菟丝子。此石产地与云母相同，而且很像云母，只是质地更浓实罢了。现在使用的出自益州，与矾石共存，颜色小黄黑的是矾石。云母的根究竟指什么不清楚？民间使用很少。《仙经》中也服用它。
【考证】这种石头以白色、肌理类似阴孽（一种病理状态）、并且夹杂带云母绿润光泽的为优良，所以《本经》说黑色的为云胆，又名地涿，服用它损害人体，黑色的阳起石必定是恶品。《本经》说生于齐山，齐山在齐州历城西北五六里处，采访调查没有找到阳起石，阳起石实际上是在齐山西北六七里的卢山出产的。《本经》说“或云山”，“云”、“卢”二字讹误了。现在泰山、沂州只有黑色的，白色的唯独产自齐州。
Taste is sweet, nature is warm, non-toxic. It primarily treats deficiency and damage caused by wind-cold, pain and numbness in the waist and legs, calms the five zang organs, and supplements qi. Also known as Shi Yi Bing (Stone Malt Cake). It grows in the earth and stones of famous mountains; it can be gathered at any time.
This stone is also a type of Stalactite (Zhongru Shi), with a shape resembling Ching Qing (Azurite) but with white and black spots; it is soft, brittle, and easily broken. It is currently found on both the east and west sides of Maoshan and in Xiping Mountain, where it can be obtained by chiseling into the soil. It is not seen used in common prescriptions, but it is used in Liu Jun Daoxian San (Master Liu's Immortal-Guiding Powder) from the *Immortal Classics* (*Xian Jing*). Furthermore, *Zhen Gao* records that Li Zheng collected and consumed it to treat wind-bi (wind-damp obstruction) and deficiency damage, thereby attaining longevity.
[Verification] During the Sui Dynasty, there was an alchemist named Hua Gong who consumed something also called Shi Nao (Stone Brain), originating from Zongli Mountain in Xuzhou. Initially found among rotten stones, it was obtained more than one zhang below the ground. It was as large as a chicken egg or a date; upon contact, it scattered like flour, appearing yellowish-white. Locals called it "Woxue Shi" (Snow-Holding Stone), claiming that consuming it grants longevity. This aligns with the case of Li Zheng.
Taste is sour, nature is warm, extremely hot, and toxic. It primarily treats vaginal erosion/ulceration in women, carbuncles and hemorrhoids, foul blood, strengthens bones and tendons, and treats alopecia capitis (scalp hair loss). It treats accumulations in the heart and abdomen, cold phlegm-rheum in the hypochondrium, cough with rebellious qi, cold painful weakness in the feet, epistaxis (nosebleed), malignant sores, lower body wet sores, stops bleeding, and kills scabies mites. It can dissolve gold, silver, copper, iron, and other strange substances. It grows in the Yangmu Valley of Donghai, as well as Mount Tai and Hexi Mountain; it is the liquid form of Alum Stone (Fan Shi).
Donghai Commandery belonged to North Xuzhou, and Jishan also has production. Currently, the first grade comes from Funan Linyi, with a color like a newly hatched goose egg, named Kunlun Huang (Kunlun Yellow). The next grade comes from foreign lands via Shu, with a deep and brilliant color. Common prescriptions use it to treat leg weakness and chronic cold conditions very effectively. The *Immortal Classics* also make considerable use of it. The "strange substances" it dissolves refer to methods in the *Huangbai Shu* (Art of Yellow and White) and elixir compounding techniques. It states here that it is the liquid of Alum Stone; however, since there is no Alum Stone in the south now, this may not be accurate.
Taste is salty, nature is slightly warm, non-toxic. It primarily treats metrorrhagia and leukorrhea (uterine bleeding and discharge), breaks up blood stasis in the child-bearing uterus, resolves masses and qi stagnation, treats alternating chills and fever, abdominal pain, infertility, impotence and sexual dysfunction, and supplements deficiencies. It treats coldness in the glans penis, damp itching in the genital area, removes foul sweat, and reduces edema. Long-term consumption prevents hunger and enables procreation. Also known as Bai Shi (White Stone), Shi Sheng (Stone Born), Yang Qi Shi (Yang Rising Stone); it is the root of Muscovite (Yun Mu). It grows in the valleys of Mount Qi and Langya Yunshan, Yangqi Mountain; it can be gathered at any time. Sang Piao Xiao (Mantis Egg Case) acts as its guiding herb; it is incompatible with Ze Xie (Alisma Rhizome), Jun Gui (Cassia Twig), Lei Wan (Polyporus Umbellatus), and Snake Skin; it fears Tu Si Zi (Cuscuta Seed). The origin of this stone is the same as Muscovite, and it resembles Muscovite greatly, but is denser and more solid. Current usage originates from Yizhou, where it coexists with Alum Stone; the yellowish-black ones are Alum Stone. It is unknown what exactly constitutes the "root of Muscovite." Common usage is rare. The *Immortal Classics* also consume it.
[Verification] This stone is considered superior if it is white, has a texture similar to Yin Nie (a pathological condition implying dark/damp accumulation), and contains greenish luster from Muscovite. Therefore, the *Shennong Bencao Jing* states that black ones are Yun Dan (Cloud Gallbladder), also known as Di Zhuo; consuming them harms the human body, and black Yang Qi Shi must be inferior/harmful. The *Bencao Jing* states it grows in Qi Mountain. Qi Mountain is located 5-6 li northwest of Licheng in Qizhou; investigations found no Yang Qi Shi there. Yang Qi Shi is actually produced in Lu Mountain, 6-7 li northwest of Qi Mountain. The *Bencao Jing*'s mention of "Yun Cloud Mountain" suggests a textual error between "Yun" and "Lu". Currently, Mount Tai and Yizhou only have black varieties, while white varieties are exclusively produced in Qizhou.
