Plants or their extracts may also have a potential therapeutic role in the treatment for diabetes. Coccinia indica (synonym Coccinia cordifolia), a herb that belongs to the Cucurbitaceae family and that grows abundantly in India, is widely used in the traditional treatment of diabetes mellitus. Coccinia leaves, when administered orally twice a day for six weeks, to patients with untreated but uncomplicated maturity onset diabetes demonstrated hypoglycemic activity with significant improvement in glucose tolerance. The aim of the present study was to evaluate the effectiveness of Coccinia Cordifolia on the blood glucose levels of newly detected type 2 diabetic patients requiring only behavioral or lifestyle intervention.
