A significant treatment × linear time interaction (P = 0.018) was observed for interval changes in SBP (Fig. 1). Levels, Some studies show that hibiscus tea may reduce cholesterol levels — another risk factor of heart disease. Some studies show that drinking hibiscus tea may help reduce systolic blood pressure levels compared to a placebo. In vitro studies show Hibiscus sabdariffa L., an ingredient found in many herbal tea blends and other beverages, has antioxidant properties, and, in animal models, extracts of its calyces have demonstrated hypocholesterolemic and antihypertensive properties. How Long Does Coronavirus Live On Surfaces? In their study, an infusion prepared with 10 g of dry calyces from H. sabdariffa in 0.5 L water (9.6 mg anthocyanins) and administered daily was compared with 25 mg captopril administered twice daily for 4 wk and SBP did not differ between the groups (ANOVA P > 0.25). Regression analysis revealed no significant predictive capability of age, gender, or dietary supplement use once baseline SBP and treatment were accounted for. Hibiscus tea may help to improve liver health. All tea bags were prepared from the same lot and a sample from this lot was retained. Much of the current research involves test-tube studies. It has few interactions with medications; however, enthusiastic hibiscus tea consumption could cause hypotension if already taking one or more high blood pressure medications. Effects of this magnitude are considered important for public health. "Roselle." The change in SBP from baseline to 6 wk was linearly correlated with baseline SBP (r = −0.421; P = 0.010) (Fig. Studies which have investigated the effects of herbal medicines on blood pressure prove that sour tea (Hibiscus sabdariffa) leaves have a remarkable effect on decreasing hypertension (10-12). Future research should consider whether combining the DASH diet with daily hibiscus tea consumption confers a greater reduction in BP than either approach alone.

The authors concluded the study results “proves the public belief and the results of in vitro studies concerning the effects of sour tea on lowering high blood pressure.” Similarly, a double-blind randomized controlled trial12 was conducted to compare the antihypertensive effectiveness of hibiscus tea with black tea in 60 type-2 diabetic patients with hypertension. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. The change in mean arterial pressure was of borderline significance compared with placebo (−4.5 ± 7.7 vs. −0.8 ± 7.4 mm Hg; P = 0.054). High blood pressure increases your risk of heart disease. Lowers Blood pressure: For all those who are on blood pressure lowering medication, or suffering from low blood pressure or hypertension, it is advised to avoid consuming hibiscus tisane. Plusieurs études suggèrent que l’infusiond’hibiscus réduit la tension artérielle très efficacement, même chez lespersonnes ayant des problèmes de santé qui augmentent leur risque d’hypertensionartérielle. Higher doses may be toxic. Anthocyanins give the plant its vibrant color. In contrast, adding hibiscus tea to each meal is simple and, as such, may be an effective strategy for controlling BP among pre- and mildly hypertensive adults. Haji Faraji and Haji Tarkhani (16) tested 54 patients, mean age 52 y, in a hospital-based, randomized, clinical trial over a 15-d period. Unless otherwise noted, results are expressed as mean ± SD. The purpose of this pilot study was to determine the anthocyanin and total phenol levels that were present in blood and urine within 1 h of consuming the hibiscus tea and in the morning after consuming a total of 3 servings of the hibiscus tea during the previous day. Therefore, we presumed that levels of these anthocyanins would not be detected in the plasma and urine samples from participants enrolled in the main study and no further analyses of these anthocyanins were conducted. Current research shows that the herbal tea may provide many health benefits: Lower The Journal of Nutrition: "Hibiscus Sabdariffa L. Tea (Tisane) Lowers Blood Pressure in Prehypertensive and Mildly Hypertensive Adults." Limitations include sample size and duration, as well as the lack of data related to the bioavailability and potential mechanisms of action of H. sabdariffa. H A Wahabi, L A Alansary, A H AL-Sabban, P Glasziuo. Author disclosures: D. L. McKay, C-Y. To determine eligibility, BP was ascertained during 2 separate baseline visits, 1 wk apart, using a standardized method. The objective of our study was to determine whether consuming hibiscus tea, in an amount readily incorporated into the diet, lowers the BP of generally healthy adults at risk of developing hypertension when compared with a placebo beverage. In our study, the difference in SBP between the placebo and hibiscus groups was 5.9 mm Hg, similar to the SBP-lowering effect obtained by following the combination DASH diet for 8 wk. (21) to achieve peak plasma concentrations. The patients were randomly allocated to the ST and BT groups and … The ACE inhibitor activity and natriuretic effects of H. sabdariffa have also been observed in human studies (18,19). Our objective in this study was to examine the antihypertensive effects of H. sabdariffa tisane (hibiscus tea) consumption in humans. Whereas the maximum hypotensive effect was observed after a few weeks of treatment, further research is warranted to understand the relative contributions of the acute and chronic actions of hibiscus. *Different from hibiscus, P < 0.05. Tsai P, McIntosh J, Pearce P, Camden B, Jordan BR. Herraro-Arellano et al. Multisystem inflammatory syndrome with refractory cardiogenic shock due to acute myocarditis and mononeuritis multiplex after SARS-CoV-2 infection in an adult. Observational studies show that diets high in plant foods are associated with a lower risk of chronic diseases, such as cardiovascular disease and some forms of cancer (1,2). One participant in the placebo group was excluded due to the presence of a peripheral vascular disease, which was not disclosed until the end of the study (Supplemental Fig. Supported by the USDA Agricultural Research Service under Cooperative Agreement no. Let’s Make Some Hibiscus Tisane! Although 66 eligible participants completed the entire 8-wk protocol, only 65 were included in the data analysis. Mojiminiyi FBO, Adegunloye BJ, Egbeniyi YA, Okolo RU. A standardized protocol was followed for each BP measurement: the appropriate cuff size for each participant was determined and the same arm and cuff were used for all measurements. Jonadet M, Bastide J, Bastide P, Boyer B, Carnat AP, Lamaison JL. The blood pressure lowering, and diuretic properties of hibiscus tisane may cause an expansion in the blood vessel and can cause serious health issues. It can decrease the effectiveness of the malaria drug chloroquine. Hibiscus Sabdariffa L. Tea (Tisane) Lowers Blood Pressure In Prehypertensive And Mildly Hypertensive Adults, Journal of Nutrition, February 2010 In this one, participants drank a cup of hibiscus tea three times a day. Paired t tests were used to compare changes with baseline values. Multiple regression was used to assess the independent predictive capability of age, gender, and dietary supplement use. Changes in SBP (A) and DBP (B) relative to baseline values in prehypertensive and mildly hypertensive adults following a 6-wk intervention with placebo beverage (n = 30) or hibiscus tea (n = 35).

At 6 wk, hibiscus tea lowered systolic BP (SBP) compared with placebo (−7.2 ± 11.4 vs. −1.3 ± 10.0 mm Hg; P = 0.030). Lowering Our Blood Pressure. In a separate pilot study, blood and urine samples were collected from 3 of the investigators to serve as reference standards for the analyses of data obtained from participants enrolled in the main study. The concentrate given to participants was composed of artificial cranberry (0.2%, v:v) and raspberry (10%, wt:v) flavor concentrates (International Flavors and Fragrances) plus a drop of commercially available red food coloring, diluted in water.
