中药特殊煎法的探讨与思考(二):后下

Discussion and consideration on special decoction method for Chinese materia medica(Ⅱ): Decoction later

"后下"是中药汤剂特殊煎法的一大特色,然而一些患者对中药煎煮时需后下的中药、后下的原因以及如何后下缺乏基本的认识或存在一定的误解,从而出现因中药煎煮不当导致的临床疗效不佳或不良反应等一系列问题。结合古今文献,尝试剖析中药后下的原因及注意事项,并对如何后下提出探索性的思考,为中药后下提供科学依据以促进临床合理用药。

＂Decoction later＂ is one characteristic feature of the special decoction of Chinese materia medica（CMM）. However, some patients have misunderstanding or lack of basic knowledge about CMM for ＂decoction later＂ leading to the bad clinical effect or even toxic effects because of inappropriate decoction. This study attempts to analyze the causes of CMM for decoction later based on ancient and modern literatures, and put forward exploratory thinking on methods for decoction later in order to provide scientific evidence for promoting clinical rational drug use for decoction later of CMM.
