The natural remedies include the chloroform extract of Malva sylvestris Linn flowers (4%), the ethanol extract of Punica granatum Linn flowers (2%), aqueous extract of Achillea kellalensis Boiss flowers (2%), and honey (2%) were used to evaluate the wound-healing activity on male Wistar rats (150-200 g) using excision and incision wound models. A 1.0×1.5-cm full thickness excision wound was made in the dorsal area of the rats. The animals were divided randomly into three groups of nine each. Group 1 was treated with nitrofurazone ointment and served as a reference standard (200 mg/kg/day); Group 2 was treated topically with the simple ointment prepared from natural remedies (200 mg/kg/day); Group 3 (control) was treated topically with the simple ointment (200 mg/kg/day). The treated animals by natural remedies showed reduction in the wound area when compared with nitrofurazone and control. Histological studies of the tissue obtained on days 6, 9, and 16 from natural remedies showed increased well-organized bands of collagen, more fibroblasts, and a few inflammatory cells when compared with the nitrofurazone and control which showed inflammatory cells, scanty collagen fibers, and fibroblasts. Enhanced wound contraction and histological findings suggest the use of natural remedies in the management of wound-healing.
