状如水沫及钟乳石，有细孔如蛀窠，白色，体虚而轻。今皮作家用磨皮垢甚妙。海中者，
味咸，入药更良。
《抱朴子》云∶烧泥为瓦，燔木为炭，水沫为浮石，此皆去其柔脆，变为坚刚也。《交

【《本草纲目》】
【集解】李时珍说：石面不常生长，也是一种祥瑞之物。有人说：发生饥荒时就会生长它。唐玄宗天宝三年（744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（809年），山西的云州、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（1012年）四月，慈州百姓饥饿，乡宁县山上生出像面粉一样的石脂，可以做成饼饵。宋仁宗嘉祐七年（1062年）三月，彭城地面生出面粉；五月，钟离县地面生出面粉。宋哲宗元丰三年（1080年）五月，青州临朐县、益都县的石头都化为面粉，人们取来食用。将这些搜集在这里，以备需要食用的人考证寻求。
【气味】味甘，性平，无毒。
【集解】李时珍说：浮石，是江海之间的细沙和水沫凝聚，日久结成而成的。形状像水沫及钟乳石，有细小的孔洞像虫蛀的巢穴，颜色白色，质地空虚而轻。现在皮革工匠用它来磨皮垢非常奇妙。产于海中的，味道咸，入药效果更好。
《抱朴子》说：烧泥土为瓦，烧木头为炭，水沫为浮石，这些都是去除了柔软脆性，变为坚硬刚强。《交州记》说：海中有浮石，轻虚可以用来磨脚，煮水喝可以止渴。就是这种。
【气味】味咸，性平，无毒。李时珍说：性小寒。
【主治】煮汁饮用，止渴，治疗淋证，杀灭野兽毒（孟诜）。止咳（陶弘景）。去除目翳（寇宗奭）。清金降火，消除积块，化解老痰（朱震亨）。消除瘤瘿、结核、疝气，下气，消除疮肿（李时珍）。
【发明】陈藏器说：水花主治远行无水时止渴，与苦栝蒌制成丸药，每天早晨服用二十丸，永远不再口渴。
朱震亨说：海石治疗老痰积块，因为咸味能软坚散结。
李时珍说：浮石是水沫凝结而成，色白而体轻，其质地玲珑，符合肺的象。气味咸寒，具有润下的作用。所以入肺清除上焦痰热，停止咳嗽并软坚散结。清肃其上源，所以又治疗各种淋证。按余琰《席上腐谈》说：肝属木，应当浮反而沉；肺属金，应当沉反而浮，为什么呢？肝实而肺虚的缘故。所以石头入水则沉，而南海有浮在水面的石头；木头入水则浮，而南海有沉在水底的香木。虚实相反如此。

[Bencao Gangmu (Compendium of Materia Medica)]
[Ji Jie (Collected Explanations)] Li Shizhen said: Shi Mian (Stone Flour) does not grow frequently; it is also considered an auspicious object. Some say it grows during times of famine. In the third year of Tianbao era under Emperor Xuanzong of Tang (744 AD), Liquan Spring gushed out in Fanhe County, Wuwei Commandery, and stones turned into flour, which poor people collected and ate. In the fourth year of Yuanhe era under Emperor Xianzong of Tang (809 AD), in the valleys of Yunzhou, Weizhou, and Daizhou in Shanxi, stones turned into flour, and people collected them to eat. In the fifth month of Xiangfu era under Emperor Zhenzong of Song (1012 AD), the people of Cizhou were starving, and in Xianning County, stone grease resembling flour grew on mountains, which could be made into cakes and pastries. In the seventh year of Jiayou era under Emperor Renzong of Song (1062 AD), in March, flour grew on the ground in Pengcheng; in May, flour grew on the ground in Zhongli County. In the fifth month of Yuanfeng era under Emperor Zhezong of Song (1080 AD), in Linqu and Yidu of Qingzhou, stones all turned into flour, and people collected them to eat. These are collected here for those who need to eat them to investigate and verify.
[Qi Wei (Flavor and Nature)] Sweet, neutral, non-toxic.
[Zhu Zhi (Main Indications)] Tonifies Qi and harmonizes the middle jiao; eating it stops hunger (Li Shizhen).
[Ri Hua Bencao (Daily Life Materia Medica)]
[Jiao Zheng (Correction)] Merged into "Shi Yi" (Supplementary Records) as Shui Hua (Water Flower).
[Shi Ming (Names)] Hai Shi (Sea Stone) [Bencao Gangmu], Shui Hua (Water Flower).
[Ji Jie (Collected Explanations)] Li Shizhen said: Fu Shi (Floating Stone) is formed by the aggregation of fine sand and water foam in rivers and seas over a long period. Its shape resembles water foam and stalactites, with fine holes like insect burrows, white in color, empty and light in texture. It is now used by leather craftsmen to polish leather dirt, which is very effective. Those from the sea taste salty and are better for medicinal use.
Baopuzi states: Burning clay makes tiles, burning wood makes charcoal, and water foam becomes floating stone; these all remove softness and brittleness, transforming into hardness and rigidity. Jiaozhou Ji states: There are floating stones in the sea, light and hollow, which can be used to file feet; boiling water to drink quenches thirst. This refers to this substance.
[Qi Wei (Flavor and Nature)] Salty, neutral, non-toxic. Li Shizhen said: Slightly cold.
[Zhu Zhi (Main Indications)] Boil juice to drink, quench thirst, treat Lin syndrome (strangury), kill wild beast poison (Meng Shen). Stop cough (Tao Hongjing). Remove nebula (Ke Zongshi). Clear Metal and descend fire, eliminate accumulations, resolve old phlegm (Zhu Zhenheng). Eliminate tumors, goiters, tubercles, and hernias, direct Qi downward, eliminate sores and swellings (Li Shizhen).
[Fa Ming (Elucidation)] Chen Cangqi said: Shui Hua (Water Flower) treats thirst when traveling far without water; combined with bitter Gua Lou (Trichosanthes fruit) into pills, taken twenty pills every morning, one will never feel thirsty again.
Zhu Zhenheng said: Hai Shi (Sea Stone) treats old phlegm and accumulations because saltiness can soften hardness.
Li Shizhen said: Fu Shi (Floating Stone) is formed from water foam, white in color and light in body, with a porous texture, corresponding to the image of the Lung. The flavor is salty and cold, possessing the function of moistening and descending. Therefore, it enters the Lung to clear heat-phlegm in the Upper Jiao, stop coughing, and soften hardness. By clearing its upper source, it also treats various types of Lin syndrome (strangury). According to Yu Yan's "Xi Shang Fu Tan": Liver belongs to Wood, which should float but sinks instead; Lung belongs to Metal, which should sink but floats instead. Why? Because the Liver is full/excess and the Lung is empty/deficient. Thus, stones sink in water, yet there are floating stones in the South Sea; wood floats in water, yet there are sunken fragrant woods in the South Sea. Such is the reversal of excess and deficiency.
[Fu Fang (Attached Prescriptions)] Twelve new prescriptions.
Persistent cough: Take Fu Shi (Floating Stone) powder with decoction, or take honey pills (Emergency Prescriptions Worth a Thousand Gold).

Head nodules and brain bi, phlegm nodules growing behind the head: The central one is called Nao (Brain), the lateral one is called Bi (Bi Syndrome). Use light, hollow, white Fu Shi (Floating Stone), calcined until carbonized (preserving nature), powdered, add a small amount of Qing Fen (Calomel), mix with sesame oil, and apply/scrape onto the area. Do not press with hands, or it will swell. Adding dried, roasted yellow cow dung is even better. Also treats head [diseases] (Directing the Source Formula).
Ear base with pus: Hai Fu Shi (Sea Floating Stone) one liang, Mo Yao (Myrrh) one qian, She Xiang (Musk) one zi. Powdered. Clean thoroughly and blow into the ear (Universal Effective Prescriptions).

Various malignant sores: Same formula as above.
[Fu Lu (Appendix)] Yun Shi (Ringed Stone) [Shi Yi]. Cangqi said: Grows at the bottom of the sea, shaped like Jiang Shi (Ginger Stone), purple-brown, extremely tight like stone, formed by saline water condensation, naturally having rings. Salty, cold, non-toxic. Mainly treats Stone Lin (Gravel Strangury); grind into juice to drink, or heat red and throw into wine to drink.
