All of the herbal teas showed strong antioxidant properties as rich sources of polyphenols. But the big finding: Most of these herbs are also mild diuretics; they make you pee. They help flush our bodies of natural waste products. (If you don’t pee enough, toxic nitrogen-based compounds from our cells build up and cause damage over time, which also may induce higher blood pressure.) More interesting—and more likely to explain Ikaria’s greater life expectancy—diuretics lower and control blood pressure.
