Again, its antioxidants must be given the credit. In one Japanese study, the antioxidants in rooibos tea were found to enhance the production of antibodies in the body, which might ward off allergies (14).
In another Italian study, nothofagin, one of the main antioxidants present in rooibos tea, was found to have the ability to treat skin allergies (15).
10. Might Reduce The Risk Of Cancer In Humans
Rooibos tea has properties that can help reduce the risk of cancer. It has been found that for many centuries, the indigenous Bushmen of South Africa have sworn by the many healthful benefits of the tea. Research conducted has suggested that the tea has the potential to ward off cancer (16).
Rooibos is found to increase those enzymes in the body that help in detoxification, which eventually helps slow down DNA mutation.
The advantage rooibos tea has over other herbal teas (like green and black teas) is that it is free of caffeine. Hence, it has close to zero toxicity, thereby being a more effective form of chemoprevention.
According to a study conducted in Japan, rooibos tea has a large amount of flavonoids and acts as a potent antioxidant (17). Hence, it can offer protection against cancer. Another North American study has also come up with similar findings (18).
A study conducted by Nutrition and Cancer in 2011 discovered the cancer preventive ability of unfermented rooibos when it helped reduce the size of esophageal papilloma in rats.
This probable protective benefit of rooibos would be due to the counteractive activity of its flavonoid groups on cancer cells. Rooibos also contains antioxidants that might protect the body cells from oxidative damage and might lower the risk of cancer.
11. Might Help Treat Gout
Rooibos can lower the activity of xanthine oxidase in the body, which is responsible for converting purine to uric acid. Excessive buildup of uric acid can lead to gout.
12. Might Help Prevent Liver Diseases
Rooibos tea contains antioxidants that can protect your liver from damage. When consumed during the initial stages of a liver problem, it can even reverse the damage. A study conducted by Physiological Research on rats found that rooibos might act as a hepatoprotective agent (an agent that prevents liver damage) when included in the diets of patients suffering from liver disease (19).
13. May Aid In The Treatment Of Diarrhea
In a study conducted in Karachi, Pakistan, rooibos tea was found to have antispasmodic effects that can help treat abdominal spasms and diarrhea (20).
Rooibos tea also exhibits antiviral activity, and it might be helpful in treating diarrhea caused by rotavirus infection (21).
14. Helps Relieve Anxiety And Mental Stress
Rooibos tea also helps relieve nervous tension because of the presence of magnesium, zinc, and iron in it. These minerals help to create a systemic balance in the brain. The tea thus promotes improved functioning of the nervous system.
It is often prescribed as an antidepressant due to its nerve-calming benefits.
Stress is one of the biggest problems today and is responsible for a number of health issues like heart diseases, obesity, asthma, anxiety and gastrointestinal troubles. A study conducted by Stellenbosch University found that the aspalathin and nothofagin compounds in rooibos tea can help reduce anxiety and stress as they help lower the production of cortisol – the stress hormone (22).
