What is Olive Leaf Extract?

The term “olive leaf” refers to a mixture of leaves and branches from both the pruning of olive trees and the harvesting and cleaning of olives. The production of olive leaves from pruning is ~25 kg per olive tree, and 5% of the weight of harvested olives collected at the oil mill can be added to that weight. Olive tree (Olea europaea L.) leaves have been widely used in traditional remedies in European and Mediterranean countries. They have been used in the human diet as extracts, herbal teas, and powder and contain several potentially bioactive compounds with a range of health benefits.

Olive leaf extract is obtained from specific parts of the olive tree and is used to build the human immune system. It is an antiviral, antibacterial and antiparasitic substance that has been used since the time of the Ancient Egyptians.

In the 1800s, olive leaf extract was used to treat malaria. In the 1960s, scientists discovered that the extract could lower blood pressure, increase blood flow in the coronary arteries and prevent intestinal muscle spasms.
