论小柴胡汤之“汗出而解”

Discussion on the mechanism of 'recovery following sweating' regarding Xiaochaihu Decoction

小柴胡汤是否为发汗剂,为何其能"汗出而解",历来存在争议。文章通过对汗出中医机制、小柴胡汤证病机、小柴胡汤主治配伍的梳理,认为汗出是人体阳气蒸化阴津从三焦出玄府而形成的,这三者功能失常往往导致汗出异常;小柴胡汤证病机主要为三焦不利,阳气被郁,阴津不布,故而汗出可受到影响;小柴胡汤能清解少阳郁结,助运中焦气津,恢复三焦通利,使机体恢复健康、津液正常输布,其后汗出是人体恢复正常的外在表现。故而,小柴胡汤虽然不是发汗剂却能病解汗出。
