茯苓潜在功用的发掘与利用

Exploitation and Utilization on Potential Function of Poria cocos

目的:以中药茯苓为例,建立一种挖掘药物潜在功能的方法,再通过系统论证使之成为确定的新功能,有利于中药应用范围的扩大和临床疗效的提高。方法:利用先前课题组建立的《普济方》数据库管理系统,对中药茯苓跨病种检索,可以得到含茯苓复方在所有疾病的分布情况,再与历代本草学著作和《中华人民共和国药典》(简称《中国药典》)所记载的功能主治相比较,经过统计分析和逻辑判断,并结合现代药理学研究成果和临床疗效评价,从而获取对茯苓传统和潜在功用的整体认识。结果:从历代本草总结出来的茯苓生津止渴、化痰、益智、固涩、止咳、止呕、活血、开胃和安胎的功效,以及古代含茯苓复方治疗虚损、呕吐、中风、消渴、咳嗽、伤寒、痉病等病症,均未被《中国药典》收录。结论:补肾强壮,止咳化痰,降逆止呕,生津止渴,息风止痉和安胎是茯苓的潜在功用,应当引起学术界的重视。
