Rooibos teas are herbal infusions made from a South African red bush and sometimes called "red tea." There are also green Rooibos teas that are just as delicious as the popular red teas. Rooibos teas are delicious iced or hot and come in a wide variety of flavors. These naturally caffeine-free teas are extremely high in antioxidants and typically Vitamin C. Rooibos teas may also help to relieve allergies, increase iron absorption, and aid in digestion. They also promote healthy skin, teeth, and bones and are suitable for those with a sensitive central nervous system.
