The Mediterranean olive tree, Olea europaea, defends itself against bacteria, fungi, parasites and insects through eutrophic compounds it produces. Its leaf extract is popular in herbal and folk remedies and has benefited individuals for 150 years. The active nutrient in the olive leaf is oleuropein, a phenolic glucoside (structurally classified as an iridoid). The olive leaf also contains the bioflavonoids rutin, luteolin, and hesperidin, which work synergistically with oleuropein to enhance its natural activity. Olive Leaf extract provides natural protection and a healthy environment for cells, without suppressing immune system function or harming beneficial microflora.
