《证类本草》是宋以前本草文献的渊薮,同时该书中也保存了大量的道教文献。从《证类本草》所固化的道教文献中可以看出道教在求得长生成仙过程中所运用的方术,主要是服饵法和外丹黄白术对宋代之前的本草学无论是内容还是其发展都起到了很大的影响。 “Written Testimonial Materia Medica” is the origin of the herbal literature before the Song Dynasty. At the same time, the book also contains a large number of Taoist literature. From the Taoist literature solidified by the “Essentials of Materia Medica,” we can see that the Taoist alchemy used in the process of obtaining the long production of immortals is mainly used in the bait method and Waidan Huang Baishu, whether it is content or its development before the Song Dynasty. All have played a big role.
