Objectives: To screen the wound healing activity of ethanol extract of Wrightia tinctoria bark using incision, excision and dead space wound models and evaluate histopathological and biochemical changes of granuloma tissue. Material and method: The bark powder of W. tinctoria was extracted with 95% ethanol by continuous heat extraction and was subjected for phytochemical investigation and screened for wound healing activity in the incision, excision and dead space wound models in rats. A supportive study made on granuloma tissue to estimate the hydroxyproline content and histopathological examination to determine the pattern of lay-down for collagen using Masson Trichrome stain. Results: Triterpenoids, steroids and saponins were found to be present in ethanol extract of the barks of W. tinctoria. In resutured incision wound model, ethanol extract showed significant breaking strength (P
