Rooibos, (pronounced /ˈrɔɪbɒs/, like "roy-boss"), Afrikaans for "red bush";
A rooibos infusion is called rooibos tea, bush tea (esp. southern Africa), redbush tea (esp. UK), South African red tea (esp. USA), or red tea. The product has been popular in southern Africa for generations and is now consumed in many countries. It is sometimes spelled rooibosch in accordance with the Dutch etymology, but "roy-boss" remains the most common modern pronunciation.
