Abstract

Woodfordia fructicosa is used traditionally for the treatment of inflammation associated with arthritis. In the present study, the anti-inflammatory activity of W. fructicosa (WFE) leaves ethanolic extract was assessed in Sprague Dawley rats by giving 200 mg/kg dose orally. Inflammation was studied by using carrageenan induced paw edema, Freund's adjuvant (FA) and monosodium iodo acetate (MIA) induced arthritis as animal models. Serum tumor necrosis factor-alpha (TNF-α) was estimated in blood sample of animals treated with FA. The one way ANOVA followed by Bonferroni's test was used for statistical analysis. WFE significantly decreased (P<0.05, P<0.001) paw thickness in carrageenan induced paw edema and FA induced arthritis. The significant decrease in knee diameter (P<0.001) in MIA induced arthritis as well as inhibitory effect (P<0.001) on elevated TNF- α was observed. These results showed that the WFEexerted an inhibitory effect on TNF-α and carrageenan paw edema which may justify its traditional use in inflammatory conditions. Thus, the study shows that leaves of W. fruticose afford anti-inflammatory activity by preventing the inflammation in different animal models.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
