Home-made Hibiscus rosasinensis tea on post-prandial blood glucose level and blood pressure: An interventional study

Abstract

Most Hibiscus tea are made with Hibiscus rosasinensis and are expensive. Although these tea are marketed indicating hypoglycemic effects, scientific data are lacking on the effect of H. rosasinensis on humans. The objective of the study was to determine the effect of home-made water extract of H. rosasinensis flower (HRWE) as a tea on post-prandial blood sugar level (PPBS) of healthy individuals compared to green tea (GT) and commercially available Hibiscus tea (CHT–H.rosasinensis+Rosehip). Fasting and PPBS [after consuming a standard diet (StD=1045Kcal), StD+GT, StD+CHT and StD+HRWE on separate days] at 15, 30, 45, 60 and 120 minutes of healthy volunteers (n=14) were measured
