Rooibos tea, a caffeine-free herbal infusion from South Africa, has long been valued for its antioxidant properties. New research suggests it may also offer significant benefits for gut health, including reducing inflammation and strengthening the intestinal barrier.
The study, conducted on porcine intestinal cells, compared the effects of fermented and unfermented rooibos extracts. Results showed that fermented rooibos reduced inflammation markers, while unfermented rooibos helped maintain a healthy gut lining by reinforcing the barrier function, which is crucial for preventing harmful substances from entering the bloodstream.
Digestive disorders such as irritable bowel syndrome (IBS), constipation, and indigestion affect over 40% of the global population, with higher prevalence in women. Poor gut health has been linked to chronic inflammation, fatigue, anxiety, and autoimmune conditions, driving interest in natural remedies like rooibos.
The study highlighted the role of polyphenols unique to rooibos, such as aspalathin and nothofagin, which are responsible for its anti-inflammatory and antioxidant effects. These compounds vary between fermented and unfermented versions due to processing differences.
While further research is needed, the findings suggest rooibos could serve as a functional food or supplement for supporting gut health. The tea is already widely consumed and is known for its rich antioxidant profile.
