Background: Argyreia nervosa (Convolvulaceae) plant is an example of hallucinogenic plant. The antiseptic, anti-inflammatory, antispasmodic, antibacterial, antiviral, antifungal, anticonvulsant, nootropic, antifertility and aphrodisiac properties have already been reported for this plant. Aim: The aim of present work was to evaluate the wound healing property in normal and diabetic animals by oral and topical administration of ethanolic extract of leaves. Materials and Methods: Phytochemical investigations showed the presence of various biochemicals (alkaloids, flavonoids, carbohydrates, triterpenoids, proteins, saponins, steroids, tannins). A single injection of alloxan monohydrate (120 mg/kg, i.p.) prepared in citrate buffer (0.1 M, pH 4.5) was administered to produce diabetes in rats and mice, after overnight fasting. Excision wounds (sized 300 mm 2 and of 2 mm depth) were used for the study of rate of contraction of wound and epithelization. The means of wound area measurement between groups at different time intervals were compared using one-way analysis of variance (ANOVA), followed by Dunnet's test. Results: Extracts of A. nervosa showed significant wound healing effect in normal (topically treated) and diabetic (both topically and orally treated) rats. In diabetic rats, the topically treated group showed more significant effect than the orally treated groups. Conclusion: The present study demonstrates that A. nervosa leaves extract applied topically promotes healing of wounds more significantly as compared to oral application, in both normal rats and alloxan induced diabetic rats, where healing is otherwise delayed.
