Hibiscus flower tea is a popular type of herbal tea which is made from the Hibiscus Sabdariffa flower commonly called the Roselle. Hibiscus tea is made from the sepals of the tropical and sub-tropical bushy annual flower, which is native to West Africa. Hibiscus plants can however, be grown easily almost all over the world, despite ice, snow, flood, drought, or poor soil and continue to bloom year after year due to its versatile and hardy nature making hibiscus tea readily available. Hibiscus Sabdariffa is part of a large genus of flowering plants called mallows and blossoms all year round.
Lowers Blood Pressure
Studies have found that hibiscus flower tea can lower the blood pressure of patients with type 2 diabetes and a study published in Journal of Nutrition found that it had a greater effect lowering systolic blood pressure than the placebo group. Until 2010, there was no solid research to support the Iranian’s claim that hibiscus flower tea really does lower blood pressure but since then several studies have been conducted. Numerous animal studies have concluded that hibiscus flower tea does reduce blood pressure in a dose dependant way. In randomized clinical trials, drinking hibiscus flower tea daily was shown to significantly reduce the systolic blood pressure and diastolic blood pressure in adults with both type 2 diabetes and who had pre to moderate essential hypertension (high blood pressure).
Hibiscus Flower Tea Boosts Immune Health

But it doesn’t stop there, hibiscus flower tea also has 85% of the vitamin B1 needed and half of the iron as well as a tonne of other essential nutrition the body needs to maintain optimal health.
Helps Reduce Depression and Anxiety
Both human clinical trials and animal studies have conducted research to support the idea that hibiscus flower tea helps to reduce symptoms of depression and anxiety. It has a somewhat indirect effect- it has a mellowing effect on the nervous system, and makes a positive mind frame more easily achieved, which in turn makes the effects of depression and anxiety lesson. A study conducted in 2012 found that the flavonoids, anthocyanins and anthocyanins in hibiscus flower tea can also lessen the symptoms of depression and anxiety.

The antioxidants which are present in hibiscus flower tea destroy these free radicals slowing down the aging process and as many studies have found, prolonging life.
