探析小柴胡汤证"但见一证便是"OACSTPCD

It is said in the 101 article of Shang Han Lun that"in Cold damaging or Wind attacking syndromes,any one manifestation of Xiaochaihu Decoction syndrome suggests the use of it.In other words,it is not necessary to find all the symptoms in clinical practice".Accurately,"any one manifestation of Xiaochaihu Decoction syndrome"refers to one or several syndromes including alteration of chill and fever,fullness and discomfort in chest and hypochondria,apathy/indifference,upset or lost in appetite as well as nausea and vomi-ting.In essence,Xiaochaihu Decoction is not only the prime curative of Shaoyang syndrome,but also can be used in other six-meridian disease.It is usually fast of transmitting and changing in Cold damaging or Wind attacking cases and the manifestations are quite differ-ent.If it is difficult to identify the meridian of the disease and there is a definite manifestation of Xiaochaihu Decoction syndrome,the decoction can be prescribed to cure the disease quickly,which is what Zhang Zhongjing really meant.In clinical practice,the prescribing principle of"any one manifestation of Xiaochaihu Decoction syndrome could determine the use of it"should be applied on the premise of Cold damaging or Wind attacking symptoms.It is necessary to combine the disease differentiation with syndrome differentiation.How-ever,it is inadvisable to rashly treat where there is only one symptom of the syndrome.Based on disease differentiation,the development rules and treatment principles of different diseases should be respected.In addition,clarify the priorities of different diseases and"re-lieve treetop in acute cases and treat root aspect in moderate cases".Secondly,the methods of syndrome differentiation should be ap-plied comprehensively.Pay attention to the overall pathogenesis to clarify treatment principles and methods,to select the best prescrip-tion among similar formulas,using the theory of"prescription syndrome".
