Scientists have isolated the unique molecule that provides olive oil with its multitude of health and life-extending benefits. Known as oleuropein, it is the polyphenol that can help lower bad cholesterol and blood pressure, protect against oxidative damage.


oleuropein olive tree olive leaf benefits

Oleuropein provides the pungent flavor found in Extra Virgin olive oils. It’s also responsible for most of olive oil’s antioxidant, anti-inflammatory, and disease-fighting characteristics.

The olive tree (Olea europaea) produces oleuropein abundantly in its leaves as well as in the olive fruit itself, and special extraction techniques now allow for the extraction of a stable, standardized form of oleuropein. That means that consumers can have access to one of the most beneficial components of olive oil without the necessity of consuming excessive amounts of olive oil.

Olive leaf extracts and their oleuropein constituents are best known for their blood pressure-lowering effects, but the latest studies reveal their health benefits extend well beyond that. Additional anti-inflammatory and antioxidant properties offer promise in fighting atherosclerosis, diabetes, neurodegenerative diseases, and even arthritis.



Some studies (scroll down for details) demonstrate that olive leaf extracts lead to significant drops in elevated blood pressure. These effects are evident when supplementation occurs either before or after the organism develop hypertension. This means that the extracts have the ability to both prevent and treat high blood pressure.

The drop in blood pressure is accompanied by reduced pressure in the heart’s left ventricle. This results in improved blood flow to the heart’s own coronary blood vessels. Additional human studies demonstrate the ability of olive leaf extracts to significantly reduce blood pressure measurements.

 A human study compared olive leaf extract against Captopril, one of the conventional drugs used for treating hypertension. In this study, patients with stage-1 hypertension (140-159 mmHg over 90-99 mmHg) took either 500 mg of olive leaf extract twice daily, or 12.5 mg of captopril twice daily, which was increased as needed to 25 mg twice daily. After 8 weeks of treatment, both groups experienced a drop in mean blood pressure from baseline (11.5 and 13.7 mmHg systolic; 4.8 and 6.4 mmHg diastolic, respectively), with no significant difference between the two groups. In other words, the olive leaf extract performed as well as the prescription drug. 


If  under medical supervision always consult your GP before taking health supplements. If pregnant or nursing consult your GP before taking health supplements. 


arterial health olive leaf


Blood pressure is only one measure of Cardiovascular Health; Arterial Health is equally important. Olive leaf extracts fight endothelial dysfunction at multiple levels. They increase the production of nitric oxide, a signaling molecule that helps relax blood vessels. They also help prevent the oxidation of LDL-cholesterol, which is one of the earliest events in developing Atherosclerosis. Oxidized LDL triggers inflammation, further damaging arteries, and olive leaf extract has multi-targeted anti-inflammatory effects.


Polyphenol compounds found in olive leaves have been shown to help directly prevent the formation of arterial plaques(and thereby reduce the risk of heart attack and stroke) in two ways. First, they reduce the production and activity of a series of “adhesion molecules.” These substances cause white blood cells and platelets to stick to arterial walls, resulting in early plaque formation. Second, they reduce platelet aggregation (clumping) by multiple mechanisms, which reduces the risk that tiny clots will form at sites of plaque to produce a stroke or heart attack.



The diabetic (and pre-diabetic) state of chronic blood sugar elevation imposes substantial oxidative stress throughout the body. Treatments for diabetes have two main goals: 1) lowering blood glucose to normal levels and 2) limiting the damage done by the inevitable blood sugar spikes that still occur.
Olive leaf extracts are showing real promise in both of these areas. In basic lab studies, Olive Leaf Extracts and Oleuropein have been found to lower blood sugar through several mechanisms.



Olive extracts help protect the brain and central nervous system from the destruction brought on by strokes and age-related degenerative conditions such as Alzheimer’s and Parkinson’s diseases. They accomplish this by suppressing inflammation and reducing the damage done by oxidative stress.




Olive Leaves and their Extracts have long been used in the Mediterranean as folk remedies for arthritis. Now, scientific evidence has proven that olive leaf extracts can in fact interfere with the development of several different kinds of arthritis, including gout, rheumatoid arthritis, and osteoarthritis.

Oleuropein, enhances the functioning of the Immune System in multiple ways. Overall, the antiviral properties of olive leaf extract can provide full cover against the major viruses responsible for upper respiratory tract infections during the flu season. In fact, researchers demonstrated that olive leaf extract was especially effective against viral infections when fever was also present. Moreover it is an effective cold and flu relief.



Olive leaf extract contains over 20 different antioxidant polyphenols. Each of these is effective against different sets of free radicals which are responsible for cells aging. Therefore, the overall antioxidant effect of the plant extract is quite significant. Olive leaf extract is a powerful natural free radical scavenger and one of the most important antioxidant herbs.

Antioxidants are important for removing free radicals especially reactive oxygen species from the body. These free radicals can damage different tissues and disrupt the balance of metabolism, hormones, neurotransmitters and other essential natural compounds in the body.
