Olive leaf is the leaf of the olive tree (Olea europaea). While olive oil is well known for its flavor and health benefits, the leaf has been used medicinally in various times and places. Natural olive leaf and olive leaf extracts (OLE), are now marketed as anti-aging, immunostimulators, and even antibiotics. Bioassays support its antibacterial, antifungal, and anti-inflammatory effects at a laboratory level. A liquid extract made directly from fresh olive leaves recently gained international attention when it was shown to have an antioxidant capacity almost double green tea extract and 400% higher than Vitamin C.
