Conditions: Psoriasis Vulgaris

Summary: we designed this study as a multicenter, randomized, double blinded and placebo-controlled clinical trial. the aim of the study is to evaluate the clinical efficacy, safety and control of recurrence rate of psoriasis with blood stasis syndrome.

psoriasis is a chronic, relapsing, inflammatory, multisystem disease characterized by infiltration of inflammatory cells, hyperplasia of epidermal keratinocytes, and abnormal differentiation. latest data estimate that the prevalence of psoriasis in adults has increased to 11.43%, which shows that the control and treatment of psoriasis is still insufficient. recent studies showed that traditional chinese medicine (tcm) is one of the effective methods for the treatment of psoriasis. more and more evidences support the recognition of psoriasis not only affects the skin, but also suffers a chronic multisystem inflammation. chinese medicine believes that the blood heat is the root of the onset of psoriasis, so the treatment of psoriasis should focus on the method of clearing heat and cooling blood. therefore, the method of promoting clearing heat and cooling blood. has always been the focus of tcm treatment and prevention of psoriasis. this multicenter, randomized, double-blind, placebo-controlled trial will provide high-quality clinical evidences for evaluating the efficacy, safety and recurrence rate of jueyin granule, a representative prescription for the treatment of psoriasis with blood heat syndrome, in the treatment of psoriasis.
