Abstract

The effects of oral and topical application of Calendula officinalis flower extract on excision wounds made in rats were checked. The parameters assessed were the days needed for re-epithelization and percentage of wound closure. The hydroxy proline and hexosamine content in the granuloma tissue of the wound was also measured. The percentage of wound closure was 90.0% in the extract-treated group, whereas the control group showed only 51.1% on the eighth day of wounding (p <.01). The days needed for re-epithelization were 17.7 for the control animals; extract treatment at a dose of 20 or 100 mg/kg b.wt reduced the period to 14 and 13 days, respectively, A significant increase was observed in the hydroxy proline and hexosamine content in the extract-treated group compared with the untreated animals. The data indicate potent wound healing activity ofC. officinalis extract.
