People use the leaves to make medicine.Banaba is used for diabetes and weight loss.The blood sugar regulating properties of corosolic acid, the active ingredient in banaba leaf, have been demonstrated in cell culture, animal, and human studies. In isolated cells, it is known to stimulate glucose uptake. In fact, some studies have shown that it can help lower blood sugar within sixty minutes. It has also been shown to help correct leptin problems and food cravings that are typically found in overweight individuals who have elevated blood sugar. The average human response is a 10-15% decrease in blood sugar within two hours of ingestion. For this reason, it is found in many sugar metabolic enhancement formulas including Jon Barron’s Glucotor.

    Key Benefits
    1️⃣ Blood Sugar Balance
    Corosolic acid enhances cellular glucose uptake by activating GLUT4 transporters, reduces starch-to-glucose conversion, and inhibits gluconeogenesis – mechanisms validated in randomized trials . A 2012 Japanese study showed 10mg daily corosolic acid reduced fasting glucose within 60 minutes .

    2️⃣ Weight Management Support
    Modulates carbohydrate metabolism to minimize fat storage. Human trials indicate improved BMI when combined with lifestyle changes .

    3️⃣ Antioxidant & Anti-Inflammatory Action
    Contains synergistic compounds like ellagitannins and gallotannins to neutralize free radicals and suppress NF-kB inflammatory pathways .

    4️⃣ Metabolic Health
    Shown to improve lipid profiles by lowering LDL cholesterol and triglycerides in metabolic syndrome patients .
