本文以“伏气学说”为指导,结合现代医学发病机制,探讨寻常型银屑病中医病因病机及血热证的治法方药;认为本病乃内生伏邪,郁于肌肤,日久化热所致;正气衰弱,外邪内扰,内外相合,蕴于血分,血热生风是其发病的根本原因;并据此确立以清热凉血为法,方选犀角地黄汤。

Guided by“Fuqi theory”and combined with modern medical pathogenesis,this article explored the pathogenesis of TCM for psoriasis vulgaris and the treatment of blood-heat syndrome.It was believed that psoriasis vulgaris was caused by hidden pathogen stagnating on the skin to be transformed into blood heat syndrome with the passing of time.Positive qi became weak and made external pathogenic factors invade human bodies,and then the combination of internal and external pathogenic factors contained in blood generated blood-heat and pathogenic qi,which was the root cause of the onset of psoriasis vulgaris.Based on this point,a treatment method aiming at removing pathogenic heat from blood was established,and the prescription Xijiao Dihuang Decoction was selected.
