Olea europaea
The botanical name for the olive tree (and/or its fruit). When used in supplements, this typically refers to olive leaf extract. Olive leaf extract has antibiotic, anti-hypertensive, and antioxidant activities, although not all of these effects have been demonstrated in human subjects.
Tyrosol, hydroxytyrosol and oleuropein are some of the bioactive compounds identified in olive leaf, and commercial extracts are often standardized for one of these compounds.
