【释名】石韦（音同“蔗”）、石皮（出自《名医别录》）、石兰。
陶弘景说：它蔓延生长在岩石上，叶片像皮革一样，所以叫石韦。
李时珍说：柔软的皮革称为韦，也是皮的意思。
【集解】《名医别录》说：石韦生长在华阴山谷的岩石上，以听不到水声和人声的地方出产的为优良。二月采集叶片，阴干。
陶弘景说：各地都有。建平出产的石韦，叶片宽大且浓绿。
苏恭说：这种植物丛生在岩石旁边的阴凉处，也不长成藤蔓。生长在古瓦屋顶上的叫做瓦韦，治疗淋证效果也很好。
苏颂说：现在晋州、绛州、滁州、海州、福州以及江宁都有出产。丛生在岩石上，叶子像柳叶，背面有毛，斑点像皮革纹理。福州还有一种石皮，三月开花，采集叶片煮成洗澡水，可以治疗风疾。
李时珍说：多生长在背阴的山崖和险峻的缝隙处。它的叶片长的接近一尺，宽一寸多，柔软坚韧像皮革，背面有黄色的毛。也有带有金星斑点的，名叫金星草。叶片越冬不凋落。又有一种像杏叶的，也生长在岩石上，药性相同。
【修治】《名医别录》说：凡入药需去掉黄色的毛。毛发射入肺中，会导致咳嗽，难以治愈。
孟诜说：入药需去掉叶梗，必须稍微炙烤后使用。另一种方法：用羊脂炒干后使用。
【气味】味苦，性平，无毒。《名医别录》说：味甘。李当之说：性微寒。
徐之才说：滑石、杏仁、射干是它的引经药，得到菖蒲则疗效更好。能制约丹砂、矾石的毒性。
【主治】治疗虚劳发热及邪气，五癃闭不通，通利小便水道（出自《神农本草经》）。止烦渴降逆气，通利膀胱胀满，补益五脏劳损，安定五脏，祛除恶风，补益精气（出自《名医别录》）。治疗淋漓不尽及遗尿（出自《日华子本草》）。炒成末，用冷酒调服，治疗发背疮（苏颂记载）。主崩漏和金创出血，清肺气（李时珍记载）。
