“阳加于阴谓之汗”之我见

My Views of Effect of Yang on Yin Producing Perspiration

对此句经文，历代医家认识不一，大致有两种观点。第一种以阴津与阳气的关系阐释，言阳气有余，内加于阴，阴得阳而外出，故谓之汗；第二种以脉候阐释，言属阳的脉体出现于属阴的脉位上，即“阴脉多阳”时，则阳迫阴津外出的汗出症。作者通过引经据典及名家医案阐述，认为“阳加于阴谓之汗”属于脉诊范畴，这种脉象实属“洪脉”之类。它不仅说明了汗与洪脉之间的关系，还说明了脉洪是热证的一个代表脉象，“汗”在这里不只是指一个症状，而是代表了一个证候。

To'effect of Yang on Yin producing perspiration'written in the classics,the medical experts of successive dynasties held different viewpoints,which could be induced to about two points.As for the first point,the explanation was made on the relationship between Yin fluid and Yang qi,by considering that excessive Yang qi affected Yin interiorly,and further Yin under effect of Yang dispersed outward forming perspiration.As for the second point,the explanation was given to pulse conditions,by thinking that the type of pulse manifesting Yang appered on the spot belonging to Yin,that is,when the type of pulse of Yin suggested excessive Yang,the symptoms of perspiration occurred as a result of Yang compelling Yin fluid to flow outward. Quoting much from the classical works and the explanations of some comments from medical experts case reports,the author considered that 'effect of Yang on Yin producing perspiration'belonged to the category diagnostic method of feeling pulse,and this type of pulse actually fell into the group of full pulse.The classical quotation not only showed the relationship between perspiration and full pulse,but also suggested that full pulse was distinct pulse condition of heat syndromes.'Perspiration'here referred not only to a certain symptom,but represented a syndrome as well.
