The study was carried out to evaluate the hypoglycaemic effect of the crude chloroform extract of Vernonia amygdalina (leaves) on blood glucose concentration (BGC) of normoglycaemic and alloxan-induced hyperglycaemic rats. Adult male albino rats were randomly allocated into four groups. Group I animals served as untreated controls to normoglycaemic group II animals. Alloxan-induced hyperglycaemic rats of group III served as untreated controls to hyperglycaemic rats of group IV. Groups II and IV animals were treated with a single intraperitoneal (IP) dose of 750 mg/kg of crude chloroform extract of V. amygdalina . Control animals of groups I and III were administered equi-volume (per kilogram of body weight) of normal saline IP. The BGCs of all animals in each group were determined at 0, 0.5, 1, 4, 8 and 24 hours post-treatment with normal saline (controls) or the crude chloroform extract (treated groups). There was significant (P V. amygdalina has a hypoglycaemic activity in both normoglycaemic and alloxan induced hyperglycaemic rats. This study lends support to the claim by herbalists of Plateau and Nassarawa States, that V. amygdalina may have an antidiabetic effect in diabetes mellitus.
