What is hibiscus?
Hibiscus (Hibiscus sabdariffa) is a dried flower used to make a vivid red, tangy tea enjoyed around the world.
Benefits of hibiscus tea
1. Rich in antioxidants
Its red color comes from anthocyanins, antioxidant compounds.
2. Traditional diuretic use
It's popularly associated with supporting fluid balance.
3. Refreshing and low-calorie
Unsweetened, it's a great alternative to sodas.
