Diastolic BP was also lower, although this change did not differ from placebo (-3.1 vs. After 6 weeks, the hibiscus tea group had decreased systolic blood pressure by 7.2 mmHg compared to 1.3 mmHg for the placebo group. The study participants were split into two groups with either 3 240-mL servings/d of brewed hibiscus tea or a placebo beverage over the course of 6 weeks. At the end of the study, the researchers found that the group that was given 2 cups of hibiscus tea a day had a 7.43 mmHg reduction in systolic blood pressure and a 6.7 mmHg reduction in diastolic blood pressure.Ī randomized, double-blind, placebo-controlled clinical trial was conducted in 65 pre- and mildly hypertensive adults not taking blood pressure (BP)-lowering medications. The study participants were divided into two groups, a control group, and a hibiscus tea group. It’s noted that elevated blood pressure is one of the most important modifiable risk factors for all-cause morbidity.Ī meta-analysis review of clinical studies conducted on hibiscus for hypertension found that, on average, hibiscus helps to lower both systolic blood pressure by -7.58 mmHg (95% confidence interval) and diastolic blood pressure by 3.53 mmHg (95% confidence interval).Ī clinical trial involving 46 individuals with stage 1 hypertension looked at the impact of hibiscus tea on blood pressure. High blood pressure is known to be linked with an increased risk of heart disease. High blood pressure, known clinically as hypertension, places extra stress on the heart which can cause it to weaken.
One of the top health benefits of hibiscus is that it may be useful in lowering blood pressure. Read on below to learn the top research-backed benefits of hibiscus extract.
A combination of human clinical trials and lab-based research has been conducted on this plant. There are various health benefits of hibiscus. Modern research indicates that hibiscus benefits the body through lowering blood pressure, balancing blood lipids, supporting liver health, and weight loss. They also contain minerals such as calcium and iron. Hibiscus calyces are high in antioxidants and contain vitamin A, vitamin C, and riboflavin (vitamin B2). Hibiscus contains deep red-colored calyces, which are harvested and dried for use in teas, capsules, and extracts. The calyx, the cup-like structure formed by the sepals, is part of the plant that is used. The scientific name for this herb is Hibiscus sabdariffa but is commonly called hibiscus or roselle. It was originally native to Western Africa, but can now be found growing around the world in warm climates.
