Olea europaea Identity & Plant Part
The botanical entity is Olea europaea L., an evergreen tree of the Oleaceae family cultivated across the Mediterranean basin. The part used is the leaf, the narrow leathery blade with a pale silvery underside. Fruit, stone, bark and pomace are not part of this ingredient, even though all of them are sold under olive names.
Olive leaf is rich in secoiridoids, with oleuropein the best known, and in phenolic compounds such as hydroxytyrosol precursors. Olive fruit extracts and olive pomace extracts draw on a different matrix, so a hydroxytyrosol description on a fruit page does not describe this leaf extract.
Olive leaf is also sold as a cut dried leaf for infusions. That cut is a tea material, not an olive leaf extract, and the 10:1 powder here is the concentrated, dispersible form of the leaf.
