(Natural News) Rooibos tea is made from the leaves of a shrub called rooibos (Aspalathus linearis), an herb indigenous to the mountainsides of the Cederberg region in South Africa. Rooibos tea is also referred to as red bush or African red tea. Traditional rooibos tea is made by fermenting the leaves, in which naturally occurring enzymes oxidize and turn the leaves from green to red. Green rooibos tea is also available, which is the unprocessed version. Although the herb is currently only harvested in South Africa, rooibos tea is available in grocery stores and online as it has become more known throughout the years for its many health benefits.
