Rooibos
Rooibos (Afrikaans for 'red bush'; scientific name Aspalathus linearis) is a member of the legume family of plants, and is commonly used to make a tisane (herbal tea). It belongs to the Aspalathus plant group, which consists of more than 200 species originating in the Cedarberg mountains of South Africa.
The leaves of the bush are harvested, bruised, and left in the sun to oxidise, after which they acquire their red colour. The resulting product is then boiled or steeped like tea to make a beverage that is enjoyed both hot and cold.
Rooibos has also found its way into health and beauty products, and was used extensively by the ancient Bushmen (San people) of the region. It is free of caffeine, and contains Aspalathin, a flavonoid present in medicinal herbs used to treat skin and circulatory disorders. It is low in tannin, which inhibits absorption of minerals, and is often used during breastfeeding to supplement iron levels. It contains traces of fluoride, calcium and manganese
