Yes, rosemary may play a role in cancer prevention. Its high antioxidant activity helps protect cells from DNA damage caused by carcinogens. Some studies suggest that regular consumption of rosemary, as part of a healthy diet, could potentially reduce the risk of cancer. However, it is important to note that while rosemary may contribute to reducing cancer risk, it should not replace proven cancer prevention strategies such as a balanced diet, regular exercise, and avoiding tobacco.
