从《神农本草经》论茯苓在经方中的应用

Application Rules of Poria in Classical Prescriptions Analyzed Based on Shennong Bencao Jing

《伤寒杂病论》中诸多药物的应用遵于《神农本草经》,二者一脉相承。茯苓在经方中的应用体现在"主胸胁逆气,忧恚,惊邪,恐悸,心下结痛,寒热烦满,咳逆,口焦舌干,利小便"等方面。其病机体现在一是"水饮内停,阻滞气机"。水气四布,无处不在,或上犯胸阳使胸胁逆满,或痰气搏结于咽引发梅核气,或寒水上冲发为奔豚悸动,或痹阻心肺发为胸痹,或停于三焦,使津液不布,发为口渴和小便不利,或水郁气结引起发热;二是"虚邪内扰、心神不宁"。茯苓可健脾利水,宁心定悸,正切"水饮内停"或"心神不宁"之病机。《伤寒杂病论》中茯苓的应用深得《本经》要领。遵《本经》对茯苓在经方中的应用进行探讨,有助于更加深刻地理解经方。
