Rooibos

Rooibos (/ˈrɔɪbɒs/ ROY-boss; Afrikaans: [ˈroːibɔs] ^ⓘ, lit. 'red bush'), or Aspalathus linearis, is a broom-like member of the plant family Fabaceae that grows in South Africa's Fynbos biome. The leaves are used to make a caffeine-free herbal infusion that has been popular in Southern Africa for generations. Since the 2000s, rooibos has gained popularity internationally, with an earthy flavour and aroma that is similar to yerba mate or tobacco.

Outside of Southern Africa, it is called bush tea, red tea, or redbush tea (predominantly in Great Britain). The name rooibos is Afrikaans deriving from rooi bos, meaning 'red bush'. The name is protected in South Africa and has protected designation of origin status in the EU.

Rooibos was formerly classified in the genus Psoralea but is now thought to be part of Aspalathus, following Dahlgren (1980). The specific name of linearis, for the plant's linear growing structure and needle-like leaves, was given by Burman (1759).
