Hibiscus sabdariffa (roselle), a tropical plant rich in polyphenols, polysaccharides, organic acids, and pectins, has been extensively reviewed for its promising anti-diabetic properties. The review highlights its multifaceted benefits: it exerts hypoglycemic effects by inhibiting carbohydrate-digesting enzymes, supports pancreatic β-cell preservation and regeneration—boosting insulin secretion and improving glucose tolerance—and improves lipid metabolism while reducing oxidative stress and inflammation. Animal experiments demonstrated roselle extracts lowering fasting blood glucose, enhancing pancreatic islet health, and mitigating obesity-related dyslipidemia. In prediabetic and diabetic patients, daily consumption of hibiscus tea, drinks, or capsules significantly reduced fasting glucose and occasionally improved insulin resistance and blood pressure. Furthermore, advanced formulations, such as nanoemulsions, show potential for sustained and enhanced delivery of its bioactive compounds.
