Maties researchers investigating whether rooibos extract has role in treating breast cancer

Researchers at Stellenbosch University are investigating whether rooibos extract could play a role in treating breast cancer, with early lab results showing promising signs.

Initial tests suggest that rooibos may slow the growth of oestrogen-driven breast cancer cells.

However, scientists caution that the research is still in its early stages.

Senior biochemistry lecturer at Stellenbosch, Dr Nicky Verhoog, said that while the findings were encouraging, rooibos is not a substitute for medical treatment.

"What this research is doing is testing its safety, specifically in women with oestrogen-sensitive breast cancer. For now, rooibos can be part of a healthy lifestyle, but it should not be seen as replacement for medical treatment."

Dr Verhoog said that pre-clinical studies were scheduled to begin in 2026.

"The plant material used to make the extract originates from the Cederberg area, where rooibos is indigenous. For everyday use, ordinary rooibos in tea form are found on supermarket shelves and it remains a healthy antioxidant-rich drink."
