The aqueous extract of C. papaya fruit (100 mg kg(-1) day(-1) for 10 days) was evaluated for its wound healing activity in streptozotocin-induced diabetic rats using excision and dead space wound models. Extract-treated animals exhibited 77% reduction in the wound area when compared to controls which was 59%. The extract treated wounds were found to epithelize faster as compared to controls. The wet and dry granulation tissue weight and hydroxyproline content increased significantly when compared to controls. The extract exhibited antimicrobial activity against the five organisms tested. Carica papaya promotes significant wound healing in diabetic rats and further evaluation of this activity in humans is suggested.
