Brief Summary

Hibiscus sabdariffa tea is commonly used all over the world by healthy individual but the tea is also employed by patients in the management of chronic diseases such as hypertension diabetes, high cholesterol, liver disease etc. Several studies in humans and animal have proved the efficacy of Hibiscus sabdariffa tea in lowering blood pressure, blood glucose level and serum total cholesterol. But no study exists on the effect of daily consumption of this tea on blood pressure, blood glucose, total cholesterol and other biochemical and hematological parameters in healthy humans. Hence this study.
