From camomile to lemongrass and turmeric, caffeine free teas draw on a vast variety of herbs, flowers, roots, spices or fruits from all over the world and from all botanical traditions. Note however that there is a big difference between “decaffeinated tea” and “caffeine-free tea”. Decaffeinated refers to teas that originally contained caffeine and underwent a process to remove most of its caffeine. Caffeine free teas, on the other hand, contain no caffeine naturally.
