《伤寒论》“去滓再煎”刍议

Discussion of redecocting with dregs in Shanghan Lun

《伤寒论》中“去滓再煎”是一种十分重要的方剂煎煮方法,对于其内涵的探讨研究须结合原文及临床实际操作,分为“柴胡汤类方”与“泻心汤类方”分别分析。“柴胡汤类方”由于柴胡用量为“半斤”,体积较大,需加大量水方可有效煎煮,去滓再煎意为浓缩药液;“泻心汤类方”去滓再煎目的在于减轻生半夏之毒性,去其毒性,而存其效用。对于张仲景学说的研究要从原文及临床实际出发,不可臆度揣测,方可了解张仲景原意,提高临床使用经方之疗效。

In the Shanghan Lun,“redecocting with dregs”is a very important method of boiling recipes.The research on its connotation must be divided into“Chaihu Decoction class”and“Xiexin Decoction class”in combination with the original and clinical practice.Since the dosage of Bupleurum is“half a catty”,the volume of“Chaihu Decoction class”is large which needs to add a large amount of water to the effectively decoction,and redecoct with dregs for concentrated liquid.The purpose of redecocting with dregs of“Xiexin Decoction class”is to reduce the toxicity of Pinellia ternata.The research on ZHANG Zhongjing’s theory should proceed from the original text and clinical practice,and it is beneficial to understand the original meaning of ZHANG Zhongjing and improve the curative effect of clinical use.
