Olive Leaf Extract Health Benefits

To further elaborate the benefits of olive leaf extract, here are the chronic diseases which the extract can assist with; plus the procedure you can follow in applying it.


Make a drop or two of olive leaf extract on a cotton ball and place on the affected area. On a study, olive leaf extract has been found to reduce the virus invading the cells in your throat through the antimicrobial and antiviral properties it possesses.


Olive leaves and extract has been used as remedies for a long time by the Mediterranean folks against arthritis. But modern science has evidence of its use against different kinds of arthritis including osteoarthritis, gout, and rheumatoid arthritis.

For example, oleuropein stops the uric acid building up by restraining xanthine oxidase–the enzyme that transforms RNA and DNA into uric acid. Oleuropein can also benefit on rheumatoid arthritis and osteoarthritis in preventing and treating its symptoms. In another study, supplemented animal models improve microscopic joint tissue appearance and joint inflammation, as well as prevent the building up of inflammatory cytokines.

Alzheimer’s and Parkinson’s

Olive leaf extract can also assist with cognitive decline. For instance, oleuropein has the ability to protect human health against Alzheimer’s. Meanwhile, it’s antioxidant can work against Parkinson’s. It was noted that the extract can prevent damage by keeping dopamine neurons. Dopamine neuron is connected with Parkinson’s disease.

High Blood Pressure

Lowering the levels of blood pressure is part of the properties of olive extract. In a 2017 animal study, blood pressure successfully drops after taking the extract. Significantly, these results occur either before or after the animals have high blood pressure. These can simply interpret that the extract can both prevent and cure hypertension.

A human study also proves these findings. Participants with a blood pressure range from 120-139 mmHg over 80-89 mmHg were given 1000 mg supplementation per day for about 8 weeks. The participants’ blood pressure levels significantly drop by 11 mmHg systolic and 4 mmHg diastolic. They also experience a decrease in their LDL cholesterol.

By reducing the blood pressure level, you are also reducing your risk of cardiovascular diseases.

Cardiovascular Diseases

On a 2015 animal study, it was assessed how the cholesterol levels of rats are affected by the extract. Significantly, rats cholesterol level decreased after 8 weeks.

The study simply shows that olive leaf extract is related to reducing cholesterol levels which has a great factor in heart problem risks.

Additionally, researchers believe that olive leaf extract can positively affect atherosclerosis–a disease which hardens and narrows the arteries and further lead to heart disease.

Type 2 Diabetes

Researchers found the link between olive leaf extract and type 2 diabetes. Olive leaf oil claims to make an improvement to cell’s insulin secretion. On the other hand, an animal study concludes the following:

  • Increase serum insulin
  • Reduce serum glucose
  • Decrease cholesterol
  • Decrease plasma, malondialdehyde, blood glucose, and other oxidative stress signs
  • Reduce the excessive amount of insulin in the blood (hyperinsulinemia)
  • Reduce hyperglycemia

However, more human studies are still needed to become a solid proof of olive extract’s positive effect on type 2 diabetes.

The development of cancer cells into tumor rely on chemical signals, which the oleuropein disrupts.
