Rooibos, also called red bush tea, is a caffeine-free herbal tea made from *Aspalathus linearis*, a plant native to South Africa. The leaves provide the antioxidants aspalathin and nothofagin.
People drink it to support relaxation and stress management, and to aid digestion. Some use it for its anti-inflammatory properties, which may support heart and skin health. Because it has no caffeine, it can be enjoyed in the evening.
Rooibos is typically brewed as a hot or iced tea and can be taken any time of day. It also comes in extract, powder, and liquid forms.
