Hibiscus Flower Extract
Hibiscus Flower Extract
Snapshot
Hibiscus flower extract is derived from the calyces of Hibiscus sabdariffa, rich in anthocyanins and organic acids that support healthy blood pressure, liver function, and antioxidant defenses.
What is Hibiscus Flower Extract?
Hibiscus flower extract comes from the dried red calyces of the roselle plant. The extract concentrates bioactive anthocyanins (delphinidin, cyanidin) and acids (hibiscus acid, citric acid) responsible for its tart flavor and therapeutic effects.
Where It Comes From
Cultivated in tropical and subtropical regions (Africa, Asia, Latin America), hibiscus calyces are harvested after flowering, dried, and processed via water or ethanol extraction to produce standardized powders or liquid extracts.
Key Nutrients & Compounds
The primary actives are anthocyanin pigments—delphinidin-3-sambubioside and cyanidin-3-sambubioside—plus hibiscus acid and citric acid. These compounds confer potent antioxidant, vasorelaxant, and diuretic properties.
Health Benefits
Hibiscus extract supports healthy blood pressure by promoting vasodilation and diuresis. Its antioxidants protect liver cells, reduce oxidative stress, and may support healthy lipid profiles. Additionally, hibiscus demonstrates mild diuretic and digestive-supportive actions.
Recommended Dosage
Standardized extracts (10–20% anthocyanins) are typically dosed at 250–500 mg twice daily. As a tea, steep 2–3 g of dried calyces in hot water for 5–10 minutes, up to three times per day.
How to Use It
Take capsules or tinctures with water, or brew as a herbal tea. Liquid extracts can be added to beverages for flavor and function.
Who Should Use It?
Ideal for individuals seeking natural support for healthy blood pressure, liver detoxification, and antioxidant protection. Those on antihypertensive medications should monitor blood pressure when starting hibiscus.
Possible Interactions or Cautions
May enhance the effects of antihypertensive or diuretic medications, leading to hypotension. High doses can cause mild stomach upset. Avoid use during pregnancy without medical advice.
Final Thoughts
Hibiscus flower extract is a flavorful, well‑researched botanical that offers cardiovascular, hepatic, and antioxidant support. When used appropriately, it provides a gentle yet effective complement to wellness routines.
