Antidiabetic effects of aqueous leaf extract of Vernonia amygdalina on serum liver markers in streptozotocin-induced diabetic albino Rats: a new data to support its Anti-diabetic effect

Abstract Background Numerous plants have been explored for their potential antidiabetic properties, and Vernonia amygdalina (VA) stands among them. This study aims to investigate the antidiabetic activities of VA and validate its efficacy. Methods An aqueous extract of Vernonia amygdalina leaves was obtained through maceration. The antidiabetic effects of this plant extract were evaluated in vivo using diabetic model rats. Albino Wistar rats were induced into a diabetic state through intraperitoneal injection of streptozocin and subsequently treated with an optimal dose of 250 mg/kg aqueous extract of VA over a 21-day period. Parameters such as body weight, blood glucose levels, and serum marker enzymes were measured. Results The results demonstrated a significant reduction (p
