ROOIBOS (Anglicised pronunciation: /ˈrɔɪbɒs/ ROY-bos ; Afrikaans
pronunciation: , meaning "red bush"; scientific name ASPALATHUS
LINEARIS) is a broom -like member of the
The generic name comes from the plant Calicotome villosa , aspalathos in Greek, which has very similar growth and flowers to the rooibos plant. The specific name linearis comes from the plant's linear growing structure and needle-like leaves.
The leaves are used to make a herbal tea called ROOIBOS or BUSH TEA
(especially in Southern Africa) or sometimes REDBUSH TEA (especially
in Great Britain). The product has been popular in

PRODUCTION AND PROCESSING
Green rooibos tea Rooibos tea in a glass A rooibos-infused liqueur and rooibos tea
Generally, the leaves are oxidised (often termed "fermentation" in common tea processing terminology). This process produces the distinctive reddish-brown colour of rooibos and enhances the flavour. Unoxidised "green" rooibos is also produced, but the more demanding production process for green rooibos (similar to the method by which green tea is produced) makes it more expensive than traditional rooibos. It carries a malty and slightly grassy flavour somewhat different from its red counterpart.
Rooibos tea is commonly prepared in the same manner as black tea and milk and sugar are added to taste. Other methods include a slice of lemon and using honey instead of sugar to sweeten. It is also served as espresso , lattes , cappuccinos or iced tea .
As a fresh leaf, rooibos has a high content of ascorbic acid (vitamin C).
Rooibos tea does not contain caffeine and has low tannin levels
compared to black tea or green tea .
The processed leaves and stems contain benzoic and cinnamic acids .

In 1772, Swedish naturalist Carl Thunberg noted, "the country people made tea" from a plant related to rooibos or redbush. Traditionally, the local people would climb the mountains and cut the fine, needle-like leaves from wild rooibos plants. They then rolled the bunches of leaves into hessian bags and brought them down the steep slopes using donkeys. The leaves were then chopped with axes and bruised with hammers, before being left to dry in the sun.
Dutch settlers to the Cape learned to drink rooibos tea as an alternative to black tea , an expensive commodity for the settlers who relied on supply ships from Europe.
In 1904, Benjamin Ginsberg ran a variety of experiments at Rondegat Farm, finally curing rooibos. He simulated the traditional Chinese method of making Keemun by fermenting the tea in barrels. The major hurdle in growing rooibos commercially was that farmers could not germinate the rooibos seeds. The seeds were hard to find and impossible to germinate commercially.
In 1930 District Surgeon and botanist Dr Pieter Le Fras Nortier began conducting experiments with the cultivation of the rooibos plant. Dr Nortier also saw the vast commercial potential the tea held for the region.
Dr Nortier cultivated the first plants at Clanwilliam on his farm Eastside and on the farm Klein Kliphuis. The tiny seeds were very difficult to come by. Dr Nortier paid the local villagers £5 per matchbox of seeds collected. An aged Khoi woman found an unusual seed source: having chanced upon ants dragging seed, she followed them back to their nest and, on breaking it open, found a granary . Dr. Nortier's research was ultimately successful and he subsequently showed all the local farmers how to germinate their own seeds. The secret lay in scarifying the seed pods. Dr Nortier placed a layer of seeds between two mill stones and ground away some of the seed pod wall. Thereafter the seeds were easily propagated. Over the next decade the price of seeds soared to an astounding £80 a pound, the most expensive vegetable seed in the world, as farmers rushed to plant rooibos. Today, the seed is gathered by special sifting processes. Dr Nortier is today accepted as the father of the rooibos tea industry. Thanks to his research, rooibos tea, originally just an indigenous drink, became an iconic national beverage and then a globalised commodity. Rooibos tea production is today the economic mainstay of the Clanwilliam district. In 1948 The University of Stellenbosch awarded Dr Nortier an Honorary Doctorate D.Sc (Agria) in recognition for his valuable contribution to South African agriculture.

LEGAL PROTECTION OF THE NAME ROOIBOS
The South African Department of Trade and Industry issued final rules on 6 September 2013 that protects and restricts the use of the names "rooibos", "red bush", "rooibostee", "rooibos tea", "rooitee" and "rooibosch" in that country, so that the name cannot be used for things not derived from the Aspalathus linearis plant. It also provides guidance and restrictions for how products which include Rooibos, and in what measures, should use the name "rooibos" in their branding.
THREAT FROM CLIMATE CHANGE
The rooibos plant is endemic to a small part of the western coast of
Western Cape province of South Africa. It grows in a symbiotic
relationship with local micro-organisms and past attempts to grow it
outside this area, in places as far afield as the
