This review explores Roselle leaves (Hibiscus sabdariffa), also known as Zobo leaves, which are widely used in cooking and traditional medicine. The plant is recognised for its various health benefits, including anti-inflammatory, anti-diabetic, anti-hypertensive, and anti-cancer effects, as well as potency against respiratory infections, skin diseases, and gastrointestinal disorders. These properties are linked to bioactive compounds such as anthocyanins, polyphenols, flavonoids, and organic acids. The review details the plant's biological properties, the responsible bioactive compounds, its proximate composition, nutrient and mineral content, physicochemical properties, and traditional uses across different cultures. It also highlights the need for further research to fully understand its pharmacology and potential therapeutic applications.
Understanding the health benefits and bioactive compounds of Roselle leaves can inform dietary choices and potentially lead to new natural remedies. This research consolidates existing knowledge, providing a foundation for future studies into its medicinal applications and nutritional value.
The abstract suggests potential for developing health products or functional foods based on Roselle leaf extracts, given its traditional medicinal uses and identified biological properties. However, it explicitly states that further research is needed to fully understand its pharmacology and therapeutic applications, indicating this is early-stage research with potential for future development in the pharmaceutical or nutraceutical sectors.

Zobo leaves, also known as Roselle leaves are leaves of the Malvaceae plant Hibiscus sabdariffa, they are a common culinary ingredient as well as a traditional medicine in many countries including their role in treating various ailments and promoting overall health. The biological properties of the leaves of this plant have been studied and found to be of benefit to general improvement of health such biological properties as anti-inflammatory, anti-diabetic, anti-hypertensive, anti-cancer effects, potency against respiratory infections, skin diseases, and gastrointestinal disorders etcetera. These all stem from the bioactive components (anthocyanins, polyphenols, flavonoids, protocatechuic acid, malic acid, ascorbic acid, hibiscus acid contained in it. Our review focuses on these biological properties of Hibiscus sabdariffa and the bioactive compounds that are responsible for them. The nature, proximate composition including nutrient and mineral content, physicochemical properties and traditional uses of the plant according to different cultures are also included in our work. Finally, the importance of further research to fully understand the pharmacology and potential therapeutic applications of Roselle leaf and its bioactive compounds are highlighted.
