Is rooibos safe for everyone?Īlthough more research is needed, rooibos is generally considered safe and free from side effects for most healthy people. Future research will hopefully establish whether the antioxidant benefits seen both in the test tube and in animal studies, translates into real anti-cancer benefits for humans. However, research has not yet confirmed whether there are sufficient levels of bio-available antioxidants in rooibos to replicate these effects. It’s worth noting that green, unfermented rooibos has higher levels of polyphenols than the traditional fermented version, and unsurprisingly demonstrates greater antimutagenic capabilities in test tube studies. The potent antioxidant content in rooibos tea may help protect against the free radical damage associated with cancer. However, because evidence is limited, further research is needed. These findings indicate a benefit for building and maintaining bone strength. Further studies suggest fermented rooibos has an inhibitory effect on osteoclast activity, the cells which break down bone. This is because some studies report beneficial effects on osteoblasts, the cells involved with building bone. May benefit bone healthĪlthough evidence is scarce, rooibos tea may promote bone health. However, more studies are needed to confirm these effects in humans. Rooibos is a rich source of the antioxidant aspalathin, which animal studies suggest helps to balance blood sugar levels and reduce insulin resistance. Rich in protective plant compounds, including polyphenols, drinking rooibos regularly may help protect against the oxidative damage associated with diabetes. The high flavonol content of rooibos tea also supports the cardiovascular system because of its anti-inflammatory and antioxidant properties, as well as its positive effect on blood fats, including cholesterol. May be heart-friendlyĭrinking rooibos appears to have beneficial effects on blood pressure by inhibiting the angiotensin-converting enzyme (ACE), which causes blood vessels to contract and blood pressure to rise. Being naturally caffeine-free, rooibos doesn’t need to undergo a decaffeination process, so its rich polyphenol content remains unaffected. Does not have a stimulatory effectĪs a naturally caffeine-free beverage, rooibos may be drunk as a fluid replacement and is suitable for those who want to avoid, or are unable to tolerate, the stimulating effects of caffeine. What are the five main health benefits of rooibos tea? 1. This makes it a good choice for those who prefer a milder tasting tea or for those who experience digestive problems following the consumption of tannin-rich drinks. There are anecdotal reports suggesting that if the tea is used as a fluid replacement throughout the day, it may help support electrolyte levels in athletes and sportspeople however, research does not support this.Ī notable property of rooibos is that it is particularly low in tannins (4.4%). These protective plant compounds may help protect against the free radical damage that leads to conditions like diabetes, heart disease and potentially cancer.įrom a micronutrient point of view and with the exception of fluoride and copper, the trace amounts of minerals in rooibos are negligible and are not going to offer the average consumer much, if any, nutritional benefits. The main nutritional benefit of rooibos tea lies in its rich antioxidant content and it being a source of some unique polyphenols, including aspalathin. What are the nutritional benefits of rooibos tea? The tea is made by cutting and bruising the leaves and stems of the plant, fermenting them in heaps and leaving them to dry in the sun – a process which turns the leaves their characteristic red-brown colour.Ī cultivated crop since the 1930s, rooibos is now exported to more than 31 countries, including the UK, Germany, China, Japan and the United States. ![]() The plant was first recorded by botanists in 1772 after they enjoyed a sweet-tasting brew offered to them by the local people. Rooibos is a popular cuppa which has been consumed in the Cedarberg mountain region of South Africa for more than 300 years.
