The use of olive leaf as a medicine dates back thousands of years, starting with the Egyptians, who attributed the leaf with divine powers and used it for mummification. Its medicinal properties are also referenced in the Bible. Moroccans have traditionally used a tea or infusion made with olive leaves to treat blood-sugar irregularities and diabetes.
Modern science has investigated and confirmed a wide variety of therapeutic properties within the olive leaf with numerous studies being performed over the last century. We now know that many of the benefits are due to the active constituents oleuropein and elenolic acid.
These compounds, along with others that work cohesively in the whole extract, have strong antioxidant and anti-inflammatory qualities, and have been shown to fight many acute and chronic diseases, including high blood pressure, common colds, malaria, HIV/AIDS, diabetes, cancer and high cholesterol.
