至于治
又说它叫“水花”。这是江海之间细小的沙粒和水沫，经过长时间凝聚凝结而成的。它有像虫蛀巢穴一样的细小孔洞。质地疏松而轻盈。颜色为白色。
产自海中的浮石味道咸，入药效果更好。（李时珍《本草纲目》）
气味咸、平。治疗疝气。化解陈年老痰。消除积聚的块状物以及肿瘤、瘿瘤和淋巴结结核。降逆下气。治疗淋证。浮石颜色白、质地轻，是肺的象征。气味咸寒，具有润下（滋润并向下通利）的作用。因此能入肺清除痰热，止咳并软化坚结，清肃上焦肺源。又用于治疗各种淋证。（李时珍《本草纲目》）
肝属木，性质应当上浮却反而下沉；肺属金，性质应当下沉却反而上浮。为什么呢？这是因为肝实而肺虚。所以石头入水会下沉，而南海有一种能浮在水面上的石头；木头入水会上浮，而南海有一种沉入水底的香木。虚实性质的相反就像这样。（余听鸿）
血淋、沙淋，小便涩滞疼痛。将浮石研成粉末，每次服用二钱，用生甘草汤调服。石淋伴有破血症状，取满一手的浮石研成粉末，用水三升、醋一升，混合煎煮至两升，澄清后，每次服用一升。小肠疝气，阴茎收缩、阴囊肿胀者，用海浮石与香附等量，研成粉末，每次服用二钱，用姜汁送服。头核脑痹（后脑勺枕骨处生的痰核，正中位置的称为脑，侧边位置的称为痹）。用白浮石烧至存性（保留药性），研成粉末，加入少许轻粉，用麻油调和涂抹。不要用手按压，按压后就会肿胀。或者加入焙干黄牛粪效果尤佳。也治疗头部疮疡。
〔论述〕 敌金丸使用浮石治疗疝气。（见《医学准绳六要》）大概疝气属于水脏偶然凝结的邪气，也似乎有类似中恶痼疾而不能立即消散的情况。然而这并非原本就存在的沉疴痼疾。就是这种水气偶然凝结，形状像石头但非常轻虚，仍然不离于浮聚之气。用浮石来对待它，本因浮石气味咸寒而入水脏，取其病结出于偶然，消散时也还借助其偶然之性，依靠气的推移来化解罢了。至于治疗……
It is also called "water flower." This refers to fine sand and water foam in rivers and seas, which condense over a long period to form stones. They have fine pores resembling insect burrows. The texture is loose and light. The color is white.
Those from the sea taste salty and are superior for medicinal use. (Li Shizhen)
The flavor is salty, and the nature is neutral. It treats hernia (Shan Qi). It resolves old phlegm, dissipates accumulations and masses, as well as tumors, goiters, and scrofula (lymph node tuberculosis). It directs Qi downward and treats strangury (Lin syndrome). Floating stone is white in color and light in weight, corresponding to the Lung organ. Its flavor is salty and cold, possessing the function of moistening and descending. Therefore, it enters the Lung to clear phlegm-heat, stop coughing, soften hardness, and clear the upper source. It is also used to treat various types of strangury. (Li Shizhen)
The Liver belongs to Wood; its nature should float but instead sinks. The Lung belongs to Metal; its nature should sink but instead floats. Why? Because the Liver is full/excess while the Lung is deficient. Thus, stones sink in water, yet there is a floating stone in the South Sea; wood floats in water, yet there is sinking agarwood in the South Sea. The reversal of excess and deficiency is like this. (Yu Tinghong)
For blood strangury and sandy strangury, with astringent and painful urination: grind Fu Shi into powder. Take two qian each time, mixed with raw Licorice Decoction (Gancao Tang). For stone strangury with hematuria: take a handful of Fu Shi, grind into powder. Add three sheng of water and one sheng of vinegar. Boil together until reduced to two sheng. Clarify the liquid. Take one sheng each time. For small intestine hernia, with retraction of the penis and swelling of the scrotum: use equal parts of Hai Fu Shi (Sea Floating Stone) and Xiang Fu (Cyperus Rhizome). Grind into powder. Take two qian each time, taken down with Ginger Juice. For head nodules and brain bi (phlegm nodules occurring at the occiput; those in the center are called Brain Bi, while those on the side are simply Bi): Burn Bai Fu Shi (White Floating Stone) until carbonized (preserving its properties), grind into powder. Add a small amount of Calomel (Qing Fen). Mix with Sesame Oil and apply topically. Do not press with hands; pressing will cause swelling. Alternatively, adding calcined yellow cow dung is particularly effective. It also treats head sores/ulcers.
[Discussion] Di Jin Wan uses Fu Shi to treat hernia. (See *Zhunsheng*) Hernia is considered an evil pathogen occasionally congealed in the Water organs. It seems similar to entrenched diseases that cannot be dispersed immediately. However, it is not originally a chronic entrenched disease. It is merely water qi occasionally congealing, taking the shape of stone but being very light and hollow, still adhering to the floating and gathering nature of Qi. Using Fu Shi to counteract it works because its salty and cold flavor enters the Water organs. It takes advantage of the fact that the congealment occurred accidentally and disperses it by relying on its accidental nature, utilizing the movement of Qi to shift it away. As for treatment...
