The anthocyanins and other antioxidants present in the calyces have been shown to lower blood pressure and cholesterol levels, making it an effective natural remedy for hypertension and a supportive agent in overall cardiovascular care.
Digestive Support
The natural acids in Roselle, such as citric and malic acid, aid in digestion.

Safety and Precautions
Roselle is generally considered safe for most individuals when consumed in food amounts. However, due to its diuretic and blood pressure-lowering effects, it should be used cautiously by those with low blood pressure or those on diuretic medications. Pregnant and breastfeeding women should consult with a healthcare provider before using Roselle supplements.
