Objective : Syndrome differentiation(辨證) has clinical importance in East Asian TraditionalMedicine. There are several ways for Syndrome differentiation. However, EightPrinciple Pattern Identification(八綱辨證) is the base of other Syndrome differentiations.
Of the physicians focused on Eight Principle Patterns(八綱), I have researched for EightPrinciple Pattern Identification concerning with Zhang Jie-Bin(張介賓), Cheng Guo-Peng(程國彭), and Jiang Han-Tun(江涵暾) in Ming(明) and Qing(淸.)Method : Applying to Eight Principle Pattern Identification, I have researched comparatively for 3 kindsfor. First, Zhang Jie-Bin's Jingyuequanshu(景岳全書) that involves Yinyangpian(陰陽篇),Liubianbian(六變辨), Biaozhengpian(表證篇), Lizhengpian(裏證篇), Xushipian(虛實篇), and Hanrepian(寒熱篇), secondly, Cheng Guo-Peng's Yixuexinwu(醫學心悟)·Hanrexushibiaoliyinyangbian(寒熱虛實表裏陰陽辨), at lastly Jiang Han-Tun's Bihuayijing(筆花醫鏡)·Biaolixushihanreyinyangbian(表裏虛實寒熱辨).
Results : All of sick cases can be explained totally by Eight Principle Patterns. Of Eight PrinciplePatterns, Yin(陰) and Yang(陽) include last Six Principle Patterns(六綱 : 表裏, 寒熱, 虛實).
Six Principle Patterns can be divided normally by 6 pulses(六脈 : 浮沈·遲數·虛實). In all ofpain cases, feeling comfortable(可按) or discomfortable(拒按) to palpation can beimportant foundation for distinguishing Xu(虛) from Shi(實). Physical constitution(體質) forHanre·Xushi(寒熱·虛實) and tongue-diagnosis(舌診) for Biaoli·Hanre(表裏·寒熱) are usedeffectively. Related with tongue-diagnosis, tongue-coating(舌苔) for Biaoli and tonguestatus(舌質) for Hanre are used effectively. Symptoms should be divided following thissequence, Biaoli → Hanre → Xushi and lastly should be summarized of Yinyang.
Conclusion : Diagnosing with Eight Principle Patterns, digestive function, urine, and feces shouldbe checked at first. In addition, the pulse, tongue, physical constitution, and goodor bad from palpation(觸診), these should be checked and give a result. And thenthe result can be an important evidence of syndrome differentiation. As a result, itwould be the best to diagnosis that discriminating the sequence asBiaoli·Hanre·Xushi and summarizing with Yinyang.
