  To observe the efficacy of Zhuhuang Granule No. 2 (ZHG2) in treating psoriasis with Liver-Qi stagnancy.
  
  
  METHODS
  Sixty-seven patients were randomly divided into two groups, the 33 patients in the control group were treated with composite indigo capsule and the 34 in the treated group treated with ZHG2, and the clinical effect, changes of main symptoms and local skin lesion after treatment were evaluated. Meanwhile, the plasma levels of substance P (SP) and vasoactive intestinal peptide (VIP) in 15 patients and 13 healthy subjects were measured using radioimmunoassay (RIA).
  
  
  RESULTS
  The total effective rate in the treated group and the control group was 97.1% and 78.8% respectively with significant difference, P < 0.05. ZHG2 showed a significant effect in reducing plasma level of SP and VIP in patients of psoriasis with Liver-Qi stagnancy.
