Hibiscus sabdariffa
Tart crimson flower with clinically proven blood pressure-lowering and antioxidant properties
About Hibiscus
Hibiscus sabdariffa, commonly known as roselle or sorrel, is one of the best-studied medicinal plants for cardiovascular health. Its vivid crimson calyces are packed with anthocyanins, organic acids, and polyphenols that give it powerful antioxidant and anti-hypertensive properties. Multiple clinical trials have confirmed that hibiscus tea can meaningfully lower both systolic and diastolic blood pressure. It has a long history of medicinal use across Africa, the Caribbean, Central America, and the Middle East, where it is consumed both as a traditional remedy and a refreshing beverage.

How to use
Steep 1-2 tsp dried hibiscus calyces in 8 oz hot water for 5-10 minutes. Do not use boiling water — 90°C is ideal to preserve antioxidants. For cold brew: steep in cold water for 4-8 hours in the refrigerator. Sweeten with honey; pairs beautifully with cinnamon, ginger, or lemon.
