Using antioxidant-rich green tea as its base, this nourishing tea comes packed with a host of immune boosting natural wonders. Echinacea has been used by indigenous peoples for millennia and is thought to boost your body's white blood cell count to fight off infections. Elderberries and rosehips are both loaded with the Vitamin C your body needs to repair and restore your immune system. Goji is thought to boost the immune system thanks to the presence of Vitamins A and C, iron and antioxidants. Sage is another ancient herb beloved for its high levels of Vitamin K. Last but not least, the mango and raspberry add a rich fruit flavor.
