【白垩是中药,方解石也是中药】

【白垩是中药,方解石也是中药】图中是白垩(读e),属于石灰石,主要成分是碳酸钙,晶体形式是方解石,烧制产生石灰。浅色,需要用力的粉笔就是它做的(容易出字的是石膏做的)。这是亿万年一层层藻类的尸骨堆积而成,这些藻类放大了看如同足球一样,外壳一片片如同牡蛎。地质史上继侏罗纪后有一个白垩纪,持续了八千万年,就是指这种矿石形成的年代。它不容易风化,比较坚硬,因此可以形成如此陡峭的悬崖。

《神农本草经》将白垩列为下品。”垩”是恶的意思,就是指不好的土地,不长粮食。土地以黄为善。李时珍将其列为土部第一种。
白垩的晶体是方解石,地质学翻译英文的方解石借用了这个词,其拉丁词根来源于”chalk”,就是粉笔。中文翻译这个名词用了一个很偏的词。如果白垩纪翻译成粉笔纪或方解石纪可能会大煞风景。(太绕)
中药白垩是不是这个呢?因为有了这个翻译,就可能把石灰石强加给白垩。如同外语心肝脾肺肾翻译进来,借用了中医词汇,结果打得一塌糊涂。也好,现在打得天下人都知道中医的脾不是西医的脾。想象一下,中医几十年的科研,脾胃不和都是做的spleen(西医脾),可笑吧。因此,很多人认为白垩不是石灰石,这个硬度大,谈不上土。认为白垩是白陶土,即高岭土。也就是说白垩指白石脂,这也不好解释。看了推上这张图有感而发#中医##中药##杨桢讲中药的故事[超话]#
