The benefits of olive leaf extract are not that much different from other plant extracts. It seems that nature provided everything that early healers needed to treat their patients. The olive leaf benefit was well known by traditional healers in the Mediterranean area, to which the tree is native.
In other areas of the world, healers used herbs and other plants that were available to them. Modern scientific research has shown that many plants have medicinal activity. The benefits of olive leaf extract include reducing inflammation and treating infection, preventing infection and strengthening the immune system. It has been used to reduce high blood pressure, high blood sugar levels and high cholesterol levels.
Traditional healers in China did not have regular access to the olive leaf benefit, but they did have an abundance of green tea leaves. Modern research has shown that antioxidants and other compounds present in the leaves have anti-inflammatory activity. The tea has been used for eliminating indigestion, supporting heart health, reducing cholesterol, treating warts and improving brain function.
