Background: Vernonia amygdalina, commonly known as bitter leaf, has been traditionally used for its potential antidiabetic properties. This study aimed to evaluate the therapeutic potential of Vernonia amygdalina extract (VAE) in ameliorating hyperglycemia using a streptozotocin (STZ) and high-fat diet (HFD)-induced rat model of diabetes. Methods: Sixty male Wistar rats were divided into six groups: normal control, diabetic control, and four treatment groups receiving different doses of VAE (100, 300, and 500 mg/kg body weight) orally for eight weeks. Diabetes was induced in rats by a single intraperitoneal injection of STZ (55 mg/kg) after four weeks of Nicotinamid feeding. Body weight, fasting blood glucose levels, HbA1c, serum insulin levels, superoxide dismutase (SOD) activity, and malondialdehyde (MDA) levels were measured. Results: Treatment with VAE significantly reduced fasting blood glucose levels in a dose-dependent manner compared to the diabetic control group (p \< 0.05). VAE administration also led to a significant decrease in HbA1c levels and an increase in serum insulin levels in a dosedependent manner (p \< 0.05). Furthermore, VAE supplementation restored SOD activity and reduced MDA levels, indicating improved antioxidant status in the treated groups (p \< 0.05). Conclusion: This study demonstrates the therapeutic potential of Vernonia amygdalina as an antidiabetic agent in the STZ and HFD-induced rat model of diabetes. VAE supplementation effectively reduced fasting blood glucose levels, improved glycemic control as indicated by reduced HbA1c levels, and enhanced insulin secretion. Moreover, VAE exhibited antioxidant activity by restoring SOD activity and reducing MDA levels. These findings suggest that Vernonia amygdalina could be a promising natural remedy for the management of diabetes. Further investigations are warranted to elucidate the underlying mechanisms and evaluate its long-term safety and efficacy in humans.

Background: The present study intended to evaluate the beneficial effects of the seagrass Halophila beccarii, against induced diabetes mellitus in rat models. Halophila beccarii is a type of Seagrass abundant in Pulicat Lake of Andhra Pradesh, India. Objective: Evaluating the anti-hyperglycemic and anti-hyperlipidemic properties of seagrass extract in comparison with standards. Materials and Methods: STZ induced diabetic rat models were adopted to analyze the effect of long-term treatment with seagrass extract on blood glucose, HbA1c and serum lipids. Results: The methanolic extract of seagrass demonstrated a significant drop of blood glucose levels (52\%), in diabetic rats, after 6 h of supplementation. After 40 days of treatment with 500 mg/day of seagrass extract, STZ diabetic rats exhibited tremendous decrease in fasting blood glucose with significant improvement in glycemic control as evidenced by controlled levels of HbA1c. Lower levels of triglycerides, total cholesterol, LDL and VLDL cholesterols and higher levels of HDL cholesterol in STZ-induced diabetic rats provided an evidence for significant anti hyperlipidemic property of seagrass extract. Conclusion: Phytochemicals of seagrass like phenols, flavonoids and bioactive lipids contribute to the anti-hyperglycemic and anti-hyperlipidemic activities and Halophila beccarii extract serves as a natural supplement in the management of diabetes.
