Keep your memory sharp and your mind focused with this gentle herbal tea blend, perfect for stirring into smoothies and juices. Red rooibos, a South African herb rich in antioxidants, serves as the earthy base of this natural mix, which is blended with memory-boosting ayurvedic herbs including ginkgo, eleuthero and gotu kola. Cranberry and orange peel add the perfect balance of fruity and tangy flavors. Stir a spoonful of the finely ground powder into your smoothie, milk or juice; blend it into ice cream, frozen yogurt or peanut butter; sprinkle on oatmeal—the possibilities are endless. From the Republic of Tea, it's 100% vegan and contains no calories, gluten, dairy or caffeine.
