Parts Used & Where Grown The leaves of basil and its many close
relatives are used as medicine. The seeds are also used

basil now grows in gardens all over the world. Three important

basil), O. gratissimum (basil), and O. sanctum (holy basil).
What Are "Star" Ratings? Our proprietary “Star-Rating” system
was developed to help you easily understand the amount of
scientific support behind each supplement in relation to a
specific health condition. While there is no way to predict
whether a vitamin, mineral, or herb will successfully treat or
prevent associated health conditions, our unique ratings tell
you how well these supplements are understood by the medical
community, and whether studies have found them to be effective
for other people. For over a decade, our team has combed through
thousands of research articles published
