How to Use Olive Leaf Extract:

Plenty of of us are familiar with olive oil and its benefits but have little to no awareness of the powerful Importance of olive leaf extract (OLE). Also referred to as oleuropein, the name of its main component, Olive Leaf Extract is derived from the leaves of the plant that bears olives, a tree called Olea Europaea. It is believed by Plenty of to help prevent cardiovascular disease, diabetes, cancer, and other issues.

Olive leaf extract has been shown to be safe and has been widely used as standard medicine in countries such as Greece, Spain, France, Turkey, Israel, Morocco, and Tunisia.  In Egypt, it has been used for hundreds and even thousands of years. It is commonly consumed in supplement form and as a tea.

Cardiovascular Disease

Heart disease is a leading killer in the United States, Europe, and Asia. Unfortunately, as greater countries adopt the Western traditions in place of their ancestral diets, heart disease will continue to move forward. In the United States, alone, deaths due to heart and vascular disease unnecessarily kill almost 1 million people every year.

Advanced glycation end products have been associated with cardiovascular disease. In a 2016 review in Food Research International, done by Dr. Mata Navarro and colleagues, it was shown that olive leaf extract inhibited the formation of the High level glycation end products, thereby helping to prevent heart disease and vascular disease.

High Blood Pressure

High blood pressure, or hypertension, is one of the leading chance factors for heart disease. More than 1 billion of the world’s 7.6 billion people have high blood pressure, which occurs when the systolic blood pressure is measured at 140 or a lot of more and diastolic blood pressure is 90 or greater.  

A 2016 study in Food & features showed that olive leaf extract could help lower blood pressure.  A 2011 analyze in Phytomedicine showed olive leaf extract, at a dose of 500 mg twice per day, could lower blood pressure similarly to the pharmaceutical drug captopril at 25 mg twice per day. No side effects were noted from the supplement.


Diabetes mellitus type 2, or diabetes as it is commonly known, is a situation that affects millions worldwide. Those with diabetes suffer from elevated sugar (glucose) levels in the blood, causing oxidative damage to blood vessels, nerves, and organs, such as the kidneys and eyes—an example of oxidation is when car becoming rusty from the impacts of weather.  Diabetes increases one’s chance of having a heart attack, stroke, foot amputation, and kidney failure.

Ninety-five % of those with diabetes have type 2 diabetes, and five per cent have type 1.  Type 2 diabetes is primarily a disease of living while type 1 is due to an autoimmune destruction of the pancreas.

Olive leaf polyphenols improve insulin sensitivity, meaning that one’s insulin works more efficiently.  In a 2013 analyze in New Zealand, 46 men were selected to receive a capsule with olive leaf extract or a placebo for 12 weeks. Those who received the olive leaf extract showed a one percent improvement in insulin sensitivity.  Plenty of studies support the idea that olive leaf extract may help in regulating blood sugar fluctuations.

Olive Oil

Help with Cancer Prevention

One hundred years ago, cancer was rare in the United States, Russia, Japan and China—now it’s a leading source of death worldwide.  

At the turn of the twentieth century, three percentage of the population in the United States suffered from cancer. By 1950, 20 per cent of the American population developed cancer. By 2000, 38 percentage of the population had cancer. Doctors predict that by 2020, one in every two people will be diagnosed with cancer at some time in their life.  A poor diet and lack of exercise are major contributors while environmental toxins, which factor oxidation to occur, also play a role.  Nutrients such as olive leaf extract may help with prevention, according to studies.

Olive leaf extract is known to contain higher amounts of polyphenols, which are micronutrients, than those in extra virgin olive oil. In a laboratory analyze, 25 healthy donor cells were provided with olive leaf extract, which resulted in anti-cancer activity.

In a different analysis, eight weeks of daily consumption of olive leaf extract showed down-regulation of cancer genes.  In other words, cancer genes were “turned off”.  

In other studies, it was shown that polyphenols were anti-inflammatory and protected against DNA damage from oxidation. This likely explains how olive leaf extract can help prevent illness.

A 2017 analyze in Biomedicine and Pharmacotherapy showed olive leaf extract may play a role in the treatment of brain cancer, a specific type called GBM or glioblastoma multiforme.  A 2015 review showed benefit in killing mesothelioma cells, a type of lung cancer, while another 2015 preliminary analyze showed a possible benefit against breast cancer cells. Results are preliminary, and one should always consult with his or her doctor before starting a supplement regimen.

Brain features

Brain disorders are expected to rise over the next several decades. These induce dementia, Alzheimer’s disease, and Parkinson’s disease, among others. A healthy diet and physical activity are crucial to keeping the brain healthy. Certain supplements can also be helpful, (Learn more about natural approaches to Alzheimer’s disease) including olive leaf extract.  

Olive leaf extract has been found to have free radical cleansing and brain-protective results. A 2017 analysis in Metabolic Brain Disease using animals showed benefit. In that analysis, test subjects who received olive leaf extract had significantly improved balance, muscle strength, and free radical cleansing levels in the brain. The findings support that olive leaf extract has brain protecting properties and may be useful in preventing the death of specific brain cells called dopaminergic neurons, which can lead to Parkinson’s disease. For this reason, it has been suggested that olive leaf extract may be useful to patients with Parkinson’s disease and may provide some shelter against Alzheimer’s disease.  

A review in the European Journal of Pharmacology using an animal model showed olive leaf extract could also reduce long-term complications from a stroke.

Antifungal, Antiviral and Antibacterial

In a analyze in Current Medical Mycology from 2015,  it was found that olive leaf extract exhibited anti-yeast consequence against Candida albicans. Candida albicans is a pathogenic yeast that is found on the skin and in the human gut flora.  In a different analysis, 150 plant extracts, including olive leaf extract, were analyzed for antiviral activity. The findings showed that olive leaf extract also had strong ability to kill viruses and may be useful in the treatment of infections caused by viruses.

Furthermore, a 2017 study in the Journal of Food Medicine showed olive leaf extract to have antibacterial properties against gram-positive bacterial strains such as staphylococcus and streptococcus.

Skin Wellness

A 2014 study in Cell Journal evaluated olive leaf extract used in the treatment of skin diseases and wounds. Using an animal model, mice received a one-centimeter long full-thickness incision and were left unsutured (the wound was not sewn shut).  Some mice were treated with topical olive leaf extract for seven days and others with only purified water. The wounds were analyzed and it was found that olive leaf extract, when applied directly to the wound, helped with skin and wound healing.

This may be useful in the recovery process after cuts and surgery. Also, due to the antioxidant properties that are in olive leaf extract, it can help prevent skin from cell damage. One analyze even showed that olive leaf extract could also help protect against skin aging.

Weight Management

A 2014 analyze in Evidence-Based Complementary and Alternative Medicine found that olive leaf extract can help against obesity by turning off the genes that create fat (thermogenesis). The results of the analyze are supportive that taking olive leaf extract may help in weight loss.

How to Use Olive Leaf Extract:

The most convenient way to receive the Importance of olive leaf extract is to purchase it in a capsule or tablet form as a natural supplement. Olive leaf extract can also be purchased in liquid form.

Olive leaf extract proposed dose: 500 mg once to twice per day

Olive leaf extract liquid: Take as directed on the label

Although there is still a lot of research to be done on olive leaf extract, there is enough evidence to support that it is beneficial to overall Wellness and well-being.
