Objective: The objective of this study was to assess the effect of ethanolic extract of Cyanotis cristata leaves when applied topically on healing of wound in Wistar rats.Methods: C. cristata leaves were evaluated for its effect on healing of wound in three models, namely, incision, excision, and burn wound. Each model included five groups, each consisting of 6 rats. The five groups were as follows: Group I rats (control and ointment base), Group II rats (standard and silver sulfadiazine), and Group III, Group IV, Group V (treated with C. cristata extract ointment of 0.5%, 1%, and 2%, respectively). Variables evaluated included breaking strength in incision wound while it was contraction rate and epithelialization in excision and burn wound. One-way analysis of variance and Tukey's post hoc test was used to analyze data.Result: In incision wound, breaking strength in test group was significantly increased (p<0.001) as compared to control. In excision and burn wound of test group, time to epithelialization and contraction rate was significantly decreased (p<0.001). The granulation tissue from excision and burn wound showed increased collagen and less inflammatory cells in test groups in comparison to the control.Conclusion: The ethanolic extract of leaves of C. cristata, when applied topically, enhanced wound strength and accelerated healing of incision, excision, and burn wounds in rats
