石面（一种生于岩石表面的矿物类物质）主要功效为补益元气、调和脾胃，食用后可止饥。（出自《本草纲目》）【产地】（李时珍说）石面不常出现，也是一种祥瑞之物。有人说在饥荒之年才会产生。（唐玄宗天宝三年）武威郡番禾县的醴泉涌出，石头化为面粉，贫苦百姓取来食用。（唐宪宗元和四年）山西云州、蔚州、代州三州的山谷间，石头化为面粉，人们取来食用。（宋真宗祥符五年四月）慈州的百姓遭遇饥荒，乡宁县的山上生出像面粉一样的石蜡，可以制作成饼饵。（宋仁宗嘉祐七年三月）彭城地下生出面粉；五月，钟离县生出面粉。（宋哲宗元丰三年五月）青州临朐、益都等地的石头都化为了面粉。
石芝（一种生于岩石上的灵芝类物质，出自《本草纲目》）主要功效为延年益寿、返老还童。（出自《品汇续集》）各种灵芝捣碎成末，或者化在水中服用，能使人身体轻健、长生不老。（出自《葛洪神仙传》）【名称】（葛洪说）灵芝分为石、木、草、菌、肉五类，接近近百种。【产地】道家有《石芝图》，石芝就是形状像灵芝的石头，生长在海边角落、名山的岛屿岸边有堆积石块的地方。【采集时间】采集时必须斋戒祭祀后取得。【用法】使用全株。【质地】其形状像肉，有头、尾、四足，像生物一样附着在大石头之间，大的重十余斤，小的重三四斤。【颜色】红色的像珊瑚，白色的像截断的脂肪，黑色的像泽漆，青色的像翠鸟的羽毛，黄色的像紫金，都光明透彻。【味道】甘、辛。【性味】温、热。【炮制】捣碎成末服用。石芝有五类，下面详细说明以便采集：
七明芝（出自《品汇分录》）○（葛洪说）生长在临近水的高山石崖之间，形状像盘碗，直径不过一尺，有茎连接缀合，高出三四寸，有七个孔的叫做七明芝，有九个孔的叫做九光芝。光芒都像星星一样，百步之内夜晚可见其光芒，常在秋分时节守候观察，捣碎服用方寸匕（古代量器，约一方寸大小的药末），入口则身体发热，五味甘甜美好，吃尽一斤即可长生不老，甚至可以夜间视物。
玉脂芝（出自《品汇分录》）○（葛洪说）生长在出产玉石的山上，玉膏流出千百年凝结而成灵芝，有鸟兽的形状，大多像玄玉、苍玉及水晶，颜色没有固定色彩，采得后捣碎成末，用无心草汁调和，须臾间变成水，服用至一升即可长生。
石蜜芝（出自《品汇分录》）○（葛洪说）生长在少室山的石户中，里面有深谷不可通过，只能望见石蜜蜂从石户上方进入石盖中间，很久之后就会有一滴蜜露，得到服用一升即可长生不老。
石桂芝（出自《品汇分录》）○（葛洪说）生长在石穴中，有枝条像桂树但果实是石头，高约一尺，颜色光明，味道辛辣。○（李时珍说）神仙的说法渺茫，不知是否有，然而其所描述的物体并非不存在。贵州普定分司署内有假山，山间有树木，根干枝条都是石头，其中有叶子像石榴树般袅袅翠绿，开花像桂花微黄。嘉靖丁巳年，佥事焦希程赋诗记录此事，将其与康王断松化石之事相比，但不知道名字。现在按照图谱及《抱朴子》的说法，这乃是石桂芝。又有海边生长的石梅，枝干横斜；石柏，叶像侧柏，也是石桂之类。

Shimian (a mineral substance growing on rock surfaces) primarily benefits Qi (vital energy), regulates the middle Jiao (digestive system), and stops hunger when consumed. (From *Bencao Gangmu*) [Origin] (Li Shizhen states) Shimian does not appear frequently; it is also considered an auspicious object. Some say it arises during times of famine. (In the 3rd year of Tianbao under Emperor Xuanzong of Tang) at Liquan in Fanhe County, Wuwei Commandery, a spring gushed forth, stones turned into flour, and poor people took it to eat. (In the 4th year of Yuanhe under Emperor Xianzong of Tang) in the valleys of Yunzhou, Weizhou, and Daizhou in Shanxi, stones turned into flour, and people took it to eat. (In the 4th month of the 5th year of Xiangfu under Emperor Zhenzong of Song) the people of Cizhou suffered from famine; on the mountains of Xiangning County, stone wax resembling flour grew, which could be made into cakes and pastries. (In the 3rd month of the 7th year of Jiayou under Emperor Renzong of Song) flour grew underground in Pengcheng; in the 5th month, flour grew in Zhongli County. (In the 5th month of the 3rd year of Yuanfeng under Emperor Zhezong of Song) stones in Linqu and Yidu of Qingzhou all turned into flour.
Shizhi (a type of Lingzhi-like fungus growing on rocks, from *Bencao Gangmu*) primarily extends life, promotes longevity, reverses aging, and restores youth. (From *Pinhui Xuji*) Various types of Lingzhi, when pounded into powder or dissolved in water and taken, make the body light and grant immortality. (From *Ge Hong Shenxian Zhuan*) [Name] (Ge Hong states) Lingzhi is divided into five categories: Stone, Wood, Grass, Fungus, and Meat, totaling nearly one hundred species. [Origin] Daoists have a "Chart of Stone Lingzhi"; Stone Lingzhi refers to stones shaped like Lingzhi, growing at sea edges, on islands of famous mountains, or along cliffs where accumulated stones exist. [Harvesting Time] Harvesting requires fasting and sacrificial rituals before taking. [Usage] The whole entity is used. [Texture] Its shape resembles meat, with a head, tail, and four limbs, appearing as a living creature attached among large stones; the large ones weigh over ten jin, and the small ones three to four jin. [Color] Red ones resemble coral, white ones resemble cut fat, black ones resemble *Zeqi* (Spurges), green ones resemble kingfisher feathers, and yellow ones resemble purple gold; all are bright and translucent. [Taste] Sweet and Pungent. [Nature] Warm and Hot. [Processing] Pounded into powder for consumption. There are five categories of Stone Lingzhi, detailed below for easy collection:
Qiming Zhi (Seven-Bright Lingzhi) (From *Pinhui Fenlu*) ○ (Ge Hong states) Grows between high mountain stone cliffs near water. Its shape resembles plates or bowls, no more than one chi in diameter, with stems connecting them, rising three to four cun. Those with seven holes are named Qiming Zhi; those with nine holes are named Jiuguang Zhi. The light shines like stars, visible within a hundred steps at night. It is usually monitored around the Autumn Equinox. When pounded and taken as one cun bi (a traditional measure of powdered medicine), the body becomes warm upon ingestion, the taste is sweet and pleasant, consuming one jin grants immortality and allows night vision.
Yuzhi Zhi (Jade Fat Lingzhi) (From *Pinhui Fenlu*) ○ (Ge Hong states) Grows on mountains producing jade. Jade paste flows out and condenses into Lingzhi over thousands of years. It takes the form of birds and beasts, mostly resembling dark jade, grey jade, and crystal. Its color varies without fixed hue. After harvesting, it is pounded into powder, mixed with juice from *Wuxin Cao* (Heartless Grass), and turns into water instantly. Consuming up to one sheng grants immortality.
Shimi Zhi (Stone Honey Lingzhi) (From *Pinhui Fenlu*) ○ (Ge Hong states) Grows in stone caves of Mount Shaoshi, containing deep valleys that cannot be crossed. One can only see stone bees entering from above the stone cave into the stone canopy. After a long time, a single drop appears. Consuming one sheng grants immortality.
Shigui Zhi (Stone Cassia Lingzhi) (From *Pinhui Fenlu*) ○ (Ge Hong states) Grows in stone caves, having branches resembling cassia trees but with stone fruits. It is about one chi high, bright in color, and pungent in taste. ○ (Li Shizhen states) Claims of immortals are vague and their existence unknown, yet the objects described are not necessarily non-existent. Within the office of the Puding Branch in Guizhou Province, there is a fake mountain. Among the stones, there are tree roots, trunks, and branches made entirely of stone. Some leaves resemble pomegranate leaves, lush and green, blooming with flowers slightly yellow like cassia. In the Ding Si year of the Jiajing reign, Assistant Censor Jiao Xicheng wrote a poem to record this, comparing it to the story of broken pines turning to stone in Kangwang, though he did not know its name. Now, according to the chart and *Baopuzi*, this is indeed Shigui Zhi. Also, stone plums growing by the sea have slanting branches; stone cypresses have leaves resembling side-cypress (*Ce Bai*). These are also categories of Stone Cassia.
