Additional comments
While they are closely related, basil (Ocimum basilicum), otherwise known as sweet basil, is not exactly the same plant as holy basil (Ocimum sanctum). Fresh or dried basil typically is used as a food ingredient, whereas holy basil normally is consumed as a herb in the U.S.
Note that while we are continually searching for new evidence specifically concerning this food, there is not much interest in it among breast cancer researchers, so few studies are available.
