大黄无利湿功效之辨析

Discussion about Rhubarb without the Action of Cleaning Damp

大黄首载于《神农本草经》,是临床上常用的一味要药。不少学者认为其有利湿之功所以治黄疸、淋证,但根据相关文献表明,此说法存在谬误,主要原因在于,治湿之法不离发汗、利小便,但大黄并无此二效,观其临床运用,可知大黄功用主要在于逐瘀泻热通腑,善治热结之证,而其所以能治疗黄疸、淋证,也是因其能祛除瘀热。

Rhubarb,first published in Shennong Bencao Jing,is a common medicine in clinical practice. Many scholars think that it has the advantage of cleaning damp so it can treat jaundice and stranguria. But according to the literature,this view may be wrong. The main reason is that the cure of wet from sweating and diuresis,but rhubarb has not this two effects. Its pharmacological action is driving blood stasis,removing heat,and clearing the organs. Because of the pharmacologic action,it can treat jaundice and stranguria.
