DEVELOPMENT: Research Funding Puts Rooibos To The Test
Recent Western Cape Business News
The SA Rooibos Council is investing over R2million in independent research this year in an ongoing programme to find out more about the properties, applications and cultivation of the Western Cape’s unique herbal brew.
Six product research grants, totalling R974 705, have recently been awarded to two existing research projects, plus four new projects. These latest grants are in addition to R1,2 million already allocated to cultivation research (plant improvement, integrated pest management and organic cultivation practices). Furthermore, rooibos research has been independently undertaken and is ongoing at international universities and research organisations as far afield as Sweden, the USA, Japan, and other countries.
The six grants were approved after a rigorous process beginning in June 2009, when a call for expression of interest in rooibos research was issued to South African universities and science councils, as well as to all members of the Indigenous Plant Use Forum.
Researchers were invited to submit expressions of interest in three broad research areas: The chemistry, biochemistry and bioactivity of rooibos; the health promoting properties of rooibos and its potential to prevent and/or treat lifestyle diseases; and genetic improvement of the rooibos plant to optimise its cultivation, disease and drought resistance and biochemical composition.
Nine applications were finally reviewed by the SA Rooibos Council’s Product Research Committee and board of directors, plus a panel of three independent scientists.
“There is a need to gather reliable information on the kind of scientific evidence that is required to substantiate health claims (on product packaging, as well as in advertising, advertorials and editorial copy) in different countries – for example South Africa, the EU, countries in the Far East, USA, Canada and Australia,” said Product Research director Mientjie Mouton.
“Extensive anecdotal evidence also suggests that rooibos has other beneficial effects not yet fully verified or understood by science. Future research challenges for rooibos include exploring its anti-allergic properties and immune-boosting effects, better understanding the active compounds in rooibos and exactly how they achieve their anti-cancer and anti-ageing effects, the optimal use of rooibos as part of a healthy lifestyle, additional comparative studies with other herbal teas, plus more human studies.”
