（出自宋代《嘉祐本草》）
【释名】磨刀石（陈藏器命名）、羊肝石（《本草纲目》命名）、砺石。
李时珍说：《尚书》记载：荆州进贡的特产是砥和砺。注解说：砥因为质地细密而得名，砺因为质地粗糙而著称。俗称它为羊肝石，是因为它的颜色和形状像羊肝。
陶弘景说：越砥，就是现在的细砺石。产于临平。
【气味】味甘，无毒。
【主治】治疗目盲、止痛、消除热毒引起的瘙痒（《名医别录》）。研磨成汁滴入眼中，可去除眼翳障膜。
烧红后投入酒中饮用，可破除血瘕引起的剧烈疼痛（陈藏器）。砺石 【主治】破除陈旧瘀血，排出石淋中的结石，消除结块积聚，驱除潜伏的鬼物邪气，烧红后投入酒中饮用。人们说：踩踏它会患带下病，不知原因所在（陈藏器）。
磨刀石（又名龙白泉粉）
【主治】敷贴治疗阴部尿疮，有效（陈藏器）。涂抹治疗瘰疬结核（李时珍）。
（出自《唐本草》）
【释名】姜石。
李时珍说：姜石因形状得名。有时写作“礓砾”，邵伯温说：天有极端的乖戾之气，地有极端的幽深之气，石头类得到这些气就成了礓砾，说的就是这个。俗写为“KT”（此处原文可能有误或特指字形，通常指姜石异体或相关字，依原文保留语境意译）。
【集解】苏恭说：姜石各地都有，生长在土石之间，形状像生姜。有五种：以颜色白且质地松软不涩口的为优良，齐州历城东产的为好。采集没有固定时间。
苏颂说：各地都有，必须不见日光随时采取，微白色的为佳。
【气味】味咸，性寒，无毒。
【主治】治疗热毒引起的豌豆疮、疔毒等肿疡（《新修本草》）。
【附方】旧方二首，新方二首。
疔疮肿痛：用白姜石粉末，与鸡蛋清调和后敷在患处，干了就更换，脓液自然会排出，效果极佳。（崔氏方）乳痈肿大如碗般肿痛：方法同上。（《外台秘要》）
产后胀满冲气导致噎塞：姜石、代赭石各等分，研成粉末，用醋糊做成梧桐子大小的丸药。每次服用三五十丸，用醋汤送服。（洁古《保命集》）
全身水肿：将姜石烧红，放入黑牛尿中，趁热服用，每天饮用一升。（《千金方》）
