Banana Flower

Banana flower (banana blossom) from Musa species is traditionally used for diabetes in Indian medicine. It contains phenolic acids, flavonoids, umbelliferone, and lupeol that inhibit carbohydrate-digesting enzymes (α-glucosidase, α-amylase) and promote glucose uptake via GLUT1/GLUT3 transporters. A 2025 double-blind RCT in prediabetic adults found fermented banana product reduced body weight, BMI, and diastolic blood pressure but did NOT significantly improve glycemic parameters. Animal studies show consistent antihyperglycemic effects, reduced HbA1c, and β-cell regeneration. Has low glycemic index and high fiber/antioxidant content. Human evidence for blood sugar effects remains limited despite promising preclinical data.

Green tea extract is obtained from green tea leaves and contains high levels of flavonoids, catechins like EGCG, and often caffeine. It might reduce oxidative stress biomarkers and cardiovascular disease risk factors and improve cognitive function. However, the quality of evidence is low to moderate, and high doses can cause liver damage.
