Rooibos Tea Extract
Rooibos is becoming more popular in Western countries particularly among health-conscious consumers, due to its high level of antioxidants such as aspalathin and nothofagin, its lack of caffeine, and its low tannin levels compared to fully oxidized black tea or unoxidized green tea leaves. Rooibos also contains a number of phenolic compounds, including flavanols, flavones, flavanones, and dihydrochalcones.
Rooibos is purported to assist with nervous tension, allergies and digestive problems. Traditional medicinal uses of rooibos in South Africa include alleviating infantile colic, allergies, asthma and dermatological problems.
Although human studies of rooibos are scarce in the scientific literature, animal studies suggest it has potent antioxidant, immune-modulating and chemopreventive effects. In addition, rooibos tea has not been found to have any adverse effects.
It is often claimed that “Green” rooibos (see above) has a higher antioxidant capacity than fully oxidized rooibos. However, one study, using two different ways of measuring antioxidant activity, found conflicting data, with green rooibos showing more activity under one measure, and less activity using the other. The study also found conflicting data when comparing both forms of rooibos to black, green, and oolong tea, although it consistently found both forms to have less activity than green tea.
A recent study performed by Japanese scientists also suggests that Rooibos tea is beneficial in the treatment of acne. This is due to levels of alpha hydroxy acid, zinc and superoxide dismutase present in the herb.
Rooibos tea extract contains many antioxidants and being one of EXO’s 17 fruit and plant extracts it alleviates allergies, asthma and helps treatment of acne.
