Antidiabetic Potential of Bimbi (Coccinia indica): A Review

Abstract

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycaemia resulting from abnormalities in insulin secretion, insulin action, or both. Medicinal plants have received considerable attention as potential sources of bioactive compounds capable of influencing glucose metabolism. Bimbi, commonly identified in the scientific literature as Coccinia indica and Coccinia grandis (L.) Voigt, is a medicinal and edible plant traditionally used in Ayurveda, particularly in the context of Prameha. The plant contains several classes of phytoconstituents, including flavonoids, glycosides, phenolic compounds, tannins, sterols, terpenoids and other secondary metabolites. Experimental investigations have demonstrated several activities relevant to diabetes, particularly inhibition of α-amylase and α-glucosidase, antioxidant effects and modulation of glucose metabolism. Chromatographic and advanced analytical investigations have further demonstrated the chemical diversity of the plant and identified potentially bioactive constituents. Animal and limited human studies have also reported favourable effects on glycaemic parameters. This review summarizes the Ayurvedic perspective, phytochemical characteristics, experimentally demonstrated antidiabetic activities, possible mechanisms of action and available clinical evidence regarding Bimbi. Current evidence supports its potential as a source of natural antidiabetic agents; however, standardization of extracts, identification of active principles and well-designed clinical studies remain necessary.
