Evaluation of analgesic activity of aqueous extract of Cinnamomum zeylanicum bark extract in mice

Abstract

The present study aims to evaluate the analgesic activity of aqueous extract of Cinnamomum zeylanicum bark in mice by using acetic acid induced writhing and formalin - induced paw licking models. The results showed a significant reducing in the number of writhing responses and a significant reduction in duration of paw-licking in both early and late phase comparing to the control group. We conclude that aqueous extract of C. zeylanicum possess analgesic activity.
