The olive leaf was first used medicinally in Ancient Egypt, and it was a symbol of power. In the early 1800s, crushed oil leaves were used in drinks for it’s health benefits. Olive leaves contain high amounts of oleuropein, making extracts a valuable source of this nutrient without the need to consume large amounts of olive oil. The leaves contain many potentially bioactive compounds that have antioxidant, antihypertensive, antiatherogenic, anti-inflammatory, hypocholesterolemic and hypoglycemic properties.
