Roselle Calyx

Roselle Calyx, the fleshy structure of *Hibiscus sabdariffa*, is rich in anthocyanins and various polyphenols, primarily functioning as a potent antioxidant through free-radical scavenging. These actions contribute to its recognized benefits for cardiovascular health by helping to lower blood pressure and cholesterol, and supporting weight management.

Origin & History

Roselle Calyx is the vibrant, fleshy cup-shaped structure of the *Hibiscus sabdariffa* flower, native to West Africa and widely cultivated across tropical and subtropical regions globally. Thriving in warm climates, these calyces are prized for their tart flavor and rich concentration of anthocyanins and organic acids. They are a potent botanical for supporting cardiovascular health, metabolic balance, and detoxification pathways.
