Objectives: The aim of this study was to investigate the antipsoriatic activity of ethanolic extract of Woodfordia fruticosa flowers (EEWF) using a novel in vivo screening model. Materials and Methods: For induction of psoriasis, 0.1 ml of prepared complete Freund's adjuvant (CFA) and formaldehyde mixture (1:10 ratio) was topically applied for 7 days on the dorsum surface of the skin of Swiss albino mice. Psoriasis severity index (PSI) was evaluated by phenotypic (redness, erythema, and scales) and histological features (epidermal thickness). Therapeutic effect of 0.05% and 0.1% (w/w) ointments of EEWF was evaluated after the induction of psoriasis. Ointments of EEWF flowers were applied once daily for 3 weeks, and antipsoriatic activity was evaluated by scoring the PSI and histological examination. Results: We observed the phenotypic and histological features and found a progressive reduction (P < 0.05) in the severity of psoriatic lesions (redness, erythema, and scales) from day 7 to 21 st day and decreased epidermal thickness in animals treated with 0.05% and 0.1% (w/w) ointments of EEWF. Conclusions: The results showed that 0.05% and 0.1% (w/w) ointments of EEWF have dose-dependent beneficial effects in CFA and formaldehyde-induced psoriasis. The present investigation revealed that W. fruticosa flowers possess potent antipsoriatic activity and can be used for psoriasis treatment.
