Effect of the roselle ( L.) calyces drink on the physiological parameters of healthy adult subjects.

The calyx of roselle ( L.) has been the focus of attention of several studies, and although earlier studies on this plant showed it to possess antilipidemic and antidiabetic activities, none of these studies have assessed the effects of this plant on the physiological parameters of healthy subjects. The present study determined the effects of roselle calyx beverages on blood pressure, abdominal circumference, body mass index (BMI), hematological and urinary parameters, and the lipid profile of healthy subjects.
