Abstract

Objectives: To analyze the effectiveness of the topical application of a standardized ethanol extract of roselle calyx in the treatment of oral mucous ulceration. Methods: Twelve Sprague Dawley rats were divided into two groups, with oral mucous ulcer being induced in all the rats. The ulcer diameter, reddish color, and the swollen membrane around the ulcer, as well as the inflammation score of the ulcer, were recorded for all animals. The negative control group was treated with aquades, while the positive control group was treated with 0.1% triamcinolone acetonide. The treatment group received the topical application of 7.5% and 15% standardized ethanol extract of roselle calyx twice a day for 3 or 7 days. On the 4th day, six rats were sacrificed, while the remaining six rats continued to receive treatment as before. On the 8th day, all the rats were sacrificed. Specimens were fixed, and histology slides were made. Further, microscopic slides were observed and scored. Result: Both the 7.5% and 15% standardized ethanol extracts of roselle calyx were found to reduce the ulcer diameter and inflammation score. No swelling or redness was observed. Conclusions: The application of 7.5% standardized ethanol extract of roselle calyx for 7 days is equally as effective as the application of 0.1% triamcinolone acetonides, except in terms of the decrease in the inflammation score.
