“半表半里”“少阳”与“膜原”探析

Analysis of "semi-exterior-interior" "shaoyang" and "Mo Yuan"

后世医家对"半表半里"主要有3种阐述,以八纲辨证解释,半表半里在表之内、里之外的病位;以经络的循行流注解释,半表半里为少阳经出表入里的门户;以温病的特定病位解释,半表半里又等同于膜原。无论是少阳病还是膜原证,皆可谓之半表半里证。虽少阳病和膜原证在热型、证候特点、治则上均有相似之处,但少阳病注重调达枢机,以柴胡汤为代表方,膜原证则重于透达膜原、疏利化浊,以达原饮为代表方。客观探析半表半里与少阳、膜原之间的关系,以中医理论为指导,提高临床疗效。

Practitioners of later generations hold three kinds of explanations about semi-exterior and semi-interior.According to the eight-principles pattern identification,semi-exterior and semi-interior is the location of disease,which is located inside the exterior and outside the interior.From the perspective of running course of channel,semi-exterior and semi-interior is the portal of shaoyang channel,which invades interior and retreats to exterior.From a particular disease location,semi-exterior and semi-interior is moyuan.Both shaoyang disease and moyuan syndrome belong to semi-exterior and semi-interior syndrome.Shaoyang disease and moyuan syndromes’heat type,pattern characteristics,therapeutic principle have similarities.However,Shaoyang disease focused on causing qi regulation and having qi reach,with Chai Hu Tang as the representative prescription.Moyuan syndrome attached importance to outthrusting the moyuan,opening the qi and removing turbidity,with Da Yuan Yin as the representative prescription.Analysis on the relationship between semi-exterior and semi-interior,shaoyang and moyuan can improve clinical efficacy guided by the theory of traditional Chinese medicine.
