The research, led by the National Institute for Occupational Health (NIOH), focuses on whether Rooibos' antioxidant properties could offer protection from long-term exposure to petrol fumes and car exhaust.

Dr Kerry Wilson, an epidemiologist with NIOH, highlighted that petrol attendants are exposed to harmful chemicals that could lead to respiratory problems, skin irritation, and even cancer. "We’re looking for ways to protect these workers, and Rooibos tea, which is caffeine-free and contains powerful antioxidants, might be a solution," she explained.

The study involves giving petrol attendants Rooibos tea to drink three times daily for six months, with blood samples taken before and after the intervention to assess any changes in oxidative stress. While the initial findings show that the chemical levels at most stations are not dangerously high, long-term exposure remains a concern.
