基于药症与方证相应探究仲景方参芪不同用之因

Discovering Reasons on ZHANG Zhongjing’s Isolation Usage of Ginseng and Astragalus in One Prescription Based on Drug Certification and Correspondence Based on Prescriptions and Syndromes

通过整理《伤寒杂病论》中人参、黄芪的药症、方证之别,探讨两者功用之异,考历代医家对参芪之别的论述。人参药症有呕吐下利、心下痞满、心烦默默、虚弱少气、脉微,方证为中焦失运、寒热错杂、水液失常、津亏血虚、血水同病、少阳枢机不利、亡阳液脱;黄芪药症有身体麻木不仁、虚劳不足、关节疼痛、汗出恶风、浮肿、黄汗、黄疸,方证为血痹虚劳、表虚风湿风水水气证。人参、黄芪均为补益之品,但仲景并不单以药物功效立方。药症与方证相应因素亦可能为其参芪不同用的主要原因,提示临床医者应谨守病机,知犯何逆,随证治之。
