Rooibos, also known as Aspalathus linearis, is a broom-like member of the plant family Fabaceae that grows in South Africas fynbos biome. The leaves of the plant are used to make a herbal tea that is called rooibos, bush tea, red tea, or redbush tea. Rooibos tea is made from the fermented leaves of the Aspalathus linearis shrub, a plant native to South Africa. The leaves undergo oxidation, which produces the distinctive reddish-brown color of rooibos and enhances the flavor. Unoxidized green rooibos is also produced, but it is more expensive than traditional rooibos due to the more demanding production process.

Rooibos tea is commonly prepared as a tisane by steeping in hot water, in the same manner as black tea. The infusion is consumed on its own or flavored by addition of milk, lemon, sugar or honey. It is also served as lattes, cappuccinos or iced tea. Rooibos tea is a caffeine-free alternative to green or black tea and has a sweet, earthy flavor. Rooibos tea is rich in antioxidants, including polyphenols like aspalathin that are unique to the plant. It also contains chemical compounds that can reduce inflammation, promote weight loss, and prevent serious illnesses like cardiovascular disease and type 2 diabetes. Rooibos tea has been linked to lower blood pressure, improved cholesterol levels, and reduced risk of developing cardiovascular disease. It can also help manage blood sugar levels and reduce the risk of developing type 2 diabetes. Rooibos tea is a good alternative to black or green tea, especially for people who want to avoid caffeine or tannins.
