You’ve probably read online some vague comments like “studies prove a positive link between hibiscus consumption and reducing cholesterol”. The jury is still out on the claims that drinking hibiscus tea can lower blood pressure, reduce inflammation and even kill intestinal worms. There is some evidence to suggest the hibiscus is a mild laxative and in some parts of Africa, people drink hibiscus tea to lower their body temperature (living in Asia, we’re familiar with the idea that eating some fruits such as lychees can make us feel hotter).
What can be said with confidence is that hibiscus is caffeine-free and virtually calorie-free. It tastes especially delicious with strawberries, which are in season in Hanoi right now.
