Chen CC, Hsu JD, Wang SF, Chiang HC, Yang MY, Kao ES, Ho YC, Wang CJ. Participants' mean SBP and DBP had to be within the specified range on both baseline visits to qualify for study participation. Lifestyle modification, including dietary change, is the recommended first-line approach to prehypertension (20). The BP measurement was then repeated every 5 min for the next 15 min. Identification and quantification of individual anthocyanins in the study beverages was achieved with HPLC (24) against a standard curve of authenticated cyanidin-3-glucoside. Urine samples for anthocyanin analysis were prepared by adding 0.2 mL of 0.44 mol/L trifluoroacetic acid to 1-mL aliquots prior to storage at −80°C. Black tea is not an inert placebo because it contains caffeine, catechins, and flavonols, compounds known to affect vasodilation. McKay DL, Chen CY, Saltzman E, Blumberg JB. Student's t test and chi-square analyses were used to compare baseline characteristics (age, gender, ethnicity, education, menopausal status, baseline BP, nutrient intake) between the placebo and experimental groups. 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). From producing proteins to secreting bile to breaking down fat, your liver … 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.

Oxford University Press is a department of the University of Oxford. Baseline characteristics of study participants1. Its mode of action may be as a potent diuretic or "water pill." Our objective in this study was to examine the antihypertensive effects of H. sabdariffa tisane (hibiscus tea) consumption in humans. It can decrease the effectiveness of the malaria drug chloroquine. At each visit, participants were queried regarding interval changes in health, as well as use of prescription and over-the-counter medications, caffeine or tobacco, and dietary supplements. Cholesterol 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. 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. The total phenol content of freshly brewed H. sabdariffa tea and placebo beverage was determined by the Folin-Ciocalteu reaction (22). In one study, people who drank hibiscus tea experienced an increase in “good cholesterol” (high-density lipoproteins) and a decrease in “bad cholesterol” (low-density lipoproteins). Participants with higher SBP at baseline showed a greater response to hibiscus treatment (r = −0.421 for SBP change; P = 0.010). 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). Although 66 eligible participants completed the entire 8-wk protocol, only 65 were included in the data analysis. B. Blumberg, no conflicts of interest. In Iran, hibiscus tea is used to treat high 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 major strengths of our study include the randomized, double-blind, placebo-controlled study design and the use of a standardized method to measure BP. The potential mechanisms of action for the BP-lowering effect of H. sabdariffa were not determined in our study but have been explored by others. Pearson correlation coefficients (r) and nominal P-values were computed to assess the linear relationship between baseline BP and change from baseline. Health. Participants were allowed to consume their beverage either hot or cold.
