The ethanol extracts of M. sylvestris and P. granatum flowers, A. communis leaves, A. euchroma roots and S. deserti stems were used to evaluate the burn healing activity in alloxan-induced diabetic rats. Burns were induced in Wistar rats divided into nine groups as following; Group-I: normal rats were treated with simple ointment base (control), Group-II: diabetic rats were treated with simple ointment base (control), Groups-III and -VII: diabetic rats were treated with simple ointment base containing of extracts (diabetic animals), Groups VIII: diabetic rats were treated with simple ointment base containing of mixed extracts, Group-IX: diabetic rats received the standard drug (Silver Sulfadiazine).
