Abstract

Background: Roselle (Hibiscus sabdariffa L.) is a plant with antihyperlipidemic and antihypertensive effects. This study aimed to evaluate the effects of roselle calyces on the serum levels of lipids and insulin, inflammation, and oxidative stress in patients with metabolic syndrome (MetS). Methods: Forty adult patients with MetS were randomly assigned to receive either 500 mg of H. sabdariffa calyx powder or placebo once daily for 4 weeks. Systolic and diastolic blood pressures (SBP and DBP) and BMI (body mass index) as well as fasting serum levels of glucose (FPG; fasting plasma glucose), insulin, lipoproteins, triglycerides (TG), high-sensitivity C-reactive protein (hs-CRP), and malondialdehyde (MDA) were determined pre-and post-intervention and compared. Results: H. sabdariffa significantly reduced serum TG (p=0.044) and SBP (p=0.049) compared to placebo. All other variables were not significantly affected by the interventions. Conclusions: Daily consumption of 500 mg of H. sabdariffa L. calyx powder can decrease SBP and serum TG in MetS patients. © 2016 by De Gruyter.
