Safety and hypoglycaemic properties of aqueous leaf extract of Ocimum gratissimum in streptozotocin induced diabetic rats.
The claim by Nigerian traditional herbal medicine practitioners that Ocimum gratissimum leaves have antidiabetic properties was investigated. Diabetes mellitus was induced with streptozotocin and graded doses of the aqueous leaf extract were administered orally to the experimentally diabetic rats for 28 days. Administration of the aqueous leaf extract caused a statistically significant reduction in plasma glucose level in streptozotocin induced diabetic rats. The extract appeared nontoxic as evidenced by normal serum levels of AST, ALT, ALP, TPT, ALB and bilirubin. These data appear to agree with claimed hypoglycaemic effects of Ocimum gratissimum.
