A scientist turning a proudly South African brew into a weapon against one of the world’s toughest diseases. Dr Taskeen Fathima Docrat from the Cape Peninsula University of Technology is leading research on Rooibos and its potential to fight Alzheimer’s.

Rooibos is truly a part of the South African heritage, and despite not growing up drinking the tea, Dr Taskeen says that she discovered its healing properties when she became a scientist. Specialising in neuro-degenerative disorders such as Alzheimer’s, she found the tea high in antioxidants and started researching it. She discovered that Rooibos has “the unique ability to protect brain cells and the kind of damage that is associated with Alzheimer’s.”

Alzheimer’s is a very challenging disease both for the patient affected by it and their family. Hoping that her research makes health more accessible and diseases more preventable, Dr Taskeen states that Rooibos is a potentially powerful tool and a low-cost alternative for neurodegeneration. She is optimistic that this very affordable, proudly South African product will become a part of people’s diet so that they can experience its long-term health benefits in preventing diseases.

Although her research is exclusively in the lab and not directly with people from the community, Dr Taskeen mentioned that when she communicates her research to people, there is always someone they know who is suffering from disease.  Empowering them with knowledge on the benefits of Rooibos and that the tea can improve their quality of life gives her “hope and validation”.

Receiving the Distinguished Young Women Researcher Award at the South African Women in Science Awards (SAWISA), presented by the Department of Science and Innovation was a “pivotal point” in her career. Taking it as a great responsibility, Dr Taskeen, through her discussions with the youth, encourages them to see science as a practical career path to “make a difference where it counts.”

Dr Taskeen says that preventative health requires a holistic approach. Start small so that you don’t feel overwhelmed. In terms of brain health, introducing small consistent habits like consuming 2-4 cups of the tea daily is what one should aim for. As Rooibos is naturally caffeine-free, it can be enjoyed at any time. Additionally, walking 30 minutes a day and getting enough sleep will enhance the effects of the tea.

She hopes that her work will contribute to a “new narrative” for SA, where unique local resources can be at the forefront of scientific discoveries. Dr Taskeen also plans for further collaboration between scientists, farmers, and industry to grow the Rooibos industry for a new line of health-focused products. She’d like to see more innovative research with homegrown produce to find solutions for health challenges that the country faces. From the lab to the community, Dr Taskeen Fathima Docrat is proving that innovation, resilience, and a little local flavour can change lives.
