Guayusa is an herbal tea made from the leaves of a holly tree native to the Amazon forest. It's renowned for its energy-inducing effects; it's got stimulating caffeine, more than most teas, as well as the soothing compound theobromine, which reduces the jittery aftereffects that your normal cup o'joe brings. It's often compared to yerba mate tea, without the bitterness, making it the perfect tea for non-tea drinkers looking to replace their sugar-ladden morning lattes.
Be sure to find 100 percent certified organic guayusa, available online or in some specialty health food stores. Brew Guayusa tea and use it as the base of your Blast!
