Olive leaf comes from the olive tree, Olea europaea, an evergreen tree in the Oleaceae family native to the Mediterranean region. The tree has narrow gray-green leaves and small fruits that mature into olives, and the leaves are the part traditionally used in herbal infusions, powders, and extracts.
In Mediterranean traditions, the olive tree has long held value as both a food and cultural plant. While olive oil and fruit are most familiar, the leaves have also been prepared as teas and extracts in broader botanical practice.
