Olive leaf has a history of use in traditional medicine, particularly in the Mediterranean, including Spain, Italy, France, Greece, Israel, Morocco, and Turkey. Its use also extends to Africa, where the Sotho, Xhosa, and Zulu tribes also use olive leaf for medicinal purposes.[1]
Traditionally, olive leaf has been used to treat diabetes, high blood pressure, and atherosclerosis. Some other traditional uses for olive leaf include use as a diuretic, emollient, fever reducer, treatment for urinary and bladder infections, and as a treatment for headaches.[2][1]
