Objectives : The aim of this study is to explore the types of pattern identification (PI, Ü©ñû) and the differential points of PI used for the treatment of psoriasis in Traditional Chinese Medicine (TCM) based on the Chinese references and to provide the evidences applying PI for the treatment of psoriasis in clinical practice.
Methods : This study extracted patterns of psoriasis through database CNKI (China National Knowledge Infrastructure) and analysis the patterns and classification criteria of the patterns. Those examined in the study are dermal symptoms, general symptoms, formula and herbs which are different depending on the patterns.
Results : Total 60 studies were selected and 44 pattern types were extracted from them. We categorized the main pattern types on psoriasis used in TCM as ¡®blood-heat syndrome(BHS, úìæðñû)¡¯, blood-stasis syndrome(BSS, úìåÜñû), and ¡®blood-dryness syndrome(BDS, úìðÏñû)¡¯, ¡®dampness-heat syndrome(DHS, ã¥æðñû)¡¯ and ¡®yang-deficiency syndrome(YDS, åÕúÈñû)¡¯. Among these patterns, BHS was the most common. In TCM, the pattern of BHS tended to have skin symptoms and signs related to inflammatory erythema and heat. Both BSS and BDS were characterized by long disease duration and poor healing. In addition, DHS tended to have the skin symptoms and signs such as oozing and severe itching. The symptoms and signs related to coldness mainly showed in YDS. For PI criteria, ¡®qi-blood-essence criteria(ѨúìòÐäûÜ©ñû)¡¯ and ¡®eight-doctrine criteria(ø¢Ë¼Ü©ñû) are commonly used.
Conclusions : Our findings show that each PI on psoriasis in TCM has different characteristics related to dermal and general symptoms or signs. Further studies are needed to develop the diagnostic tool of PI on psoriasis reflecting on clinical practices in Korean Medicine by referring to the findings of this study about PI on psoriasis in TCM.
