Hibiscus tea is obtained from Hibiscus sabdariffa and is a potent antioxidant (8). Also, it does not contain any caffeine. Scientists have found that drinking this tea can help lower blood pressure, and hence, it is good for those suffering from hypertension. Hypertension causes stress, which, in turn, increases toxins in the body, leading to inflammation. And when your body is in a constant state of inflammation, it prevents fat metabolism, and this leads to weight gain. American scientists have also found that it helps lower LDL-cholesterol and improves blood lipid profile (9).
