Wound Healing Historically, medicinal use of olive leaf has been for treatment of fevers and for the topical treatment of wounds or infection. As a poultice, it was also used by herbalists to treat skin rashes and boils. 
Heart Health Olive leaf has a wide number of constituents, including oleuropein and several types of flavonoids (e.g., rutin, apigenin, luteolin).  While olive leaf is traditionally associated with a wide number of medicinal claims, few of these have been verified by experimental study. In an animal study, oleuropein (when given by injection or in IV form) was found to decrease blood pressure (e.g., systolic and diastolic) and dilate the coronary arteries surrounding the heart.  This ability to lower blood pressure may justify the traditional use of olive leaf in the treatment of mild to moderate hypertension.  However, human studies are needed to clearly establish olive leaf as a potential treatment for high blood pressure.
Cholesterol An in vitro study has revealed that oleuropein inhibits the oxidation of LDL cholesterol. LDL oxidation can lead to the development of atherosclerosis.  This action may provide one clue as to why those consuming a Mediterranean-based diet may lower their risk of developing atherosclerosis.
Antibacterial Oleuropein from olives may have antibacterial properties. When unheated olives are brined to preserve them, oleuropein is converted into another chemical called elenolic acid. Elenolic acid has shown antibacterial actions against several species of Lactobacilli and Staphylococcus aureus and Bacillus subtilus in an in vitro study. 
Lowers Blood Sugar Olive leaf extracts have been employed experimentally to lower elevated blood-sugar levels in animals with diabetes.
