The effect of roselle leaf ( < em > Hibiscus sabdariffa L < /em > .) extract gel on wound healing

This study aimed to assess the effect of roselle leaf extract on wound healing in rats. This was an experimental laboratory study with a posttest-only control group design. There were 30 rats divided into 5 groups: negative control, 5%, 10%, and 15% roselle leaf extract, and positive control (bioplacenton). The parameters assessed in this research were wound size and histological assessment. The data were analyzed using ANOVA. P<0.05 was considered statistically significant. Wound healing percentage and epithelial thickness in the 15% group were the largest (84.17%; 64.69 µm). The lowest value was recorded in placebo (64%; 36.33 µm). Meanwhile, wound healing percentage and epithelial thickness of rats in the 5% and 10% groups were 68.53%, 43,57 µm, and 78.11%, 56.49 µm, respectively. Finally, positive control had a 77.44% wound healing percentage and 49.7 µm epithelial thickness. There were no significant differences in wound healing and epithelial thickness among the groups. Roselle leaf extract at 15% concentration showed greater wound healing properties based on clinical and histological assessment. Although there were no statistically significant differences, roselle leaf showed an opportunity to be further investigated as a potential wound healing therapy.PMID:36420282 | PMC:PMC9675303 | DOI:10.25122/jml-2021-0425
