Yes, drinking agua de Jamaica every day is safe for most people. In fact, it has a surprisingly nourishing beverage. In addition to being ridiculously delicious, hibiscus iced tea is loaded with vitamins, minerals, and antioxidants that benefit immune, cardiovascular, liver, and even reproductive health.  However, not everyone should drink agua de Jamaica every day. For example, it is so effective at lowering blood pressure that it could cause issues for anyone who struggles with low blood pressure. Women who are pregnant (or trying to be) should probably avoid it as well, due to its effects on hormone balance.
