Rooibos Tea and Health: A Systematic Review of the Evidence from the Last Two Decades:
“Rooibos tea, also known as Red Bush, is derived from the South African Cape fynbos plant, Aspalathus linearis, and is caffeine-free and abundant in polyphenols.
Evidence related to the health aspects of drinking Rooibos tea is advancing but does not appear to have been collated. Therefore, we aimed to examine the health effects of Rooibos tea through a systematic review of the literature.
A search was undertaken (2000 up to June 2020) for human and laboratory studies investigating the efficacy of Rooibos in relation to health. Seven human studies and 49 laboratory studies were identified.
Overall Rooibos tea consumption seems to benefit the lipid and redox profiles of those at risk of cardiovascular disease. It also appears to possess other promising ‘general’ effects on glycaemic control, bone, liver, cognitive and respiratory health.”
