《神农本草经》

《神农本草经》，又称《本草经》或《本经》，中医四大经典著作之一。作为现存最早的中药学著作，约起源于神农氏，代代口耳相传，于东汉时期集结整理成书，是秦汉时期众多医学家搜集、总结、整理当时医药学经验成果而形成的专著，是对中国中医药的第一次系统总结。书中规定的大部分中药学理论和配伍规则以及提出的“七情和合”原则，在中国几千年中医用药实践中发挥了巨大作用，是中医药物学理论发展的源头。在李时珍《本草纲目》出版之前，该书一直被视为最权威的医书。

《神农本草经》全书分三卷，载药365种，以三品分类法，分上、中、下三品，文字简练古朴，成为中药理论精髓。书中每味药都按药名、异名、性味、主治病证、生长环境等分别阐述，大多数为临床常用药物，朴实有验。据当地村医杨申相介绍，书中所著的许多单行药，至今仍在民间广为习用。
