Find a selection of our Rooibos tea range here. Rooibos is made from the leaves and twigs of the South African Rooibos plant. Because of its colour, it is also sometimes referred to as the ‘red tea’. Due to its richness in iron, it is a natural immune system booster and helps fight free radicals. Naturally caffeine free, rooibos has a naturally sweet and slightly nutty flavour.
