Olive Leaf Extract is a natural botanical product that has been a subject of study since the early 1800's. This specific extract of olive leaves (Olea europea) is manufactured under strict quality control conditions and is standardized to contain a minimum of 18% Oleuropein a bitter glucoside and other active constituents. We add synergistic Echinacea angustifolia to complement the standardized Olive Leaf. Echinacea is a Native American herb that was once widely used by the Plains Indians and is now used by millions of consumers worldwide.Other products from HerbsPro
