Rooibos, or red tea, is a plant native to the Cape Town region of South Africa. Long used as a beverage tea, it was popularized as a medicinal herb in the late 1960s by a woman named Annique Theron, who claimed that it could help relieve colic and other infant-related problems. Since then, it has been advocated for a wide variety of additional conditions, including stomach distress (dyspepsia), allergies, warts, eczema, anxiety, insomnia and minor injuries.

The tea is harvested during the summer. It is green when picked, but becomes red during a fermentation process similar to that used for making black tea.
