Olive Leaf Extract Benefits

The list of olive leaf extract benefits is quite impressive. From its humble beginnings as a treatment for colds, fever, and skin infections, the simple olive leaf has advanced to superstar status. Thanks to advances in science and technology, (and of course the people who’ve done the scientific studies), in the last 30 to 40 years, we’ve learnt a lot more about the remarkable healing properties of olive leaf extract.

let us know what are these benefit for human of olive leaf extract. According to various study there are many different benefits are there but here we discuss some major 11 benefits which is helps you health improvement.

Laboratory studies show that the healing compounds in olive leaf extract have the ability to:

Limit or destroy a broad spectrum of disease-carrying organisms. (bacteria, viruses, parasites and fungi or yeasts)
Strengthen and support the body’s natural immunity
Protect against tissue damage from oxidation, by neutralising many different groups of free radicals

  • Maintain good heart and blood vessel health
  • Help maintain younger-looking skin
  • Raise energy levels
  • Reduce cholesterol
  • Reduce inflammation
  • Lower blood sugar
  • Reduce excess weight
  • Assist in treating some cancers

Olive Leaf Extract Benefit for Reducing  or Destroy Micro-organism

The micro-organisms that promote disease or ill-health in humans have various names and types, so it can sometimes be confusing when the literature on olive leaf extract benefits, lists such properties as antimicrobial, antibacterial, antiviral, antifungal and antiparasitic. The anti part is obvious. The other parts refer to the different organisms that are affected.


The simple answer is that olive leaf extract either kills the microbe, parasite or fungus: or it stops it from spreading (replicating, reproducing more of itself). This allows the person’s own immune system to then more easily deal with the infection. Exactly how it does it, is not within the scope of this particular article.

It is certainly good to know that if antibiotics can’t help, then maybe olive leaf extract can.

Now, I’m definitely NOT suggesting that you skip the visit to your doctor or stop the antibiotics that you are on. If you are that sick that you need medicine, you need a qualified person to assist your return to health.

However, for non-life threatening infections; such as colds, psoriasis, and thrush perhaps, olive leaf extract might be a good alternative to drugs.

Olive Leaf Extract Benefit for support the Immune System

Unlike antibiotics, olive leaf extract does NOT harm the beneficial bacteria. It supports the immune system by assisting in the elimination of harmful microbes, without upsetting the friendly bacteria that help to keep you healthy.

This means that it can be taken prophylactically to prevent microbial infections from taking hold, for example at times when your body is a bit run down or when there is a greater risk of infection.

Examples of when your immune system might need a helpful dose of
olive leaf extract are:

Times of greater emotional or physical stress

Travelling on public transport, particularly long trips on planes

Eating out, if you think the hygeine and food quality could be a bit dodgy

Travelling overseas and eating different food and drinking different water

The times when you most succumb to colds, flu, sinusitis or hayfever

Before or after using public swimming pools

If there is a flu or stomach bug going around at your place of study or work

Before or after an operation. (check with your doctor first though)

If you are visiting a sick friend or relative

Olive Leaf Extract Benefit to Protect Tissue Damage

Antioxidants have become a bit of a buzz word in the food industry. These remarkable nutrients are highly valued for their ability to protect the body from free radical damage. Oxidative stress and free-radical damage are linked to such health conditions as heart disease, Alzheimer’s disease and arthritis. They also have a part to play in ageing, skin damage from exposure to sun, and in cancer.

What Are Free Radicals?

Free radicals are molecules with a missing component. They have an unpaired electron (negatively charged particle), which makes them unstable. To regain molecular balance, they will attack other healthy molecules in order to steal an electron, which may then turn that molecule into a free radical. This starts a chain reaction which can result in destruction of tissue.  

Antioxidants have the ability to neutralize free radicals. They can be compared to a generous neighbor, because they happily donate an electron to the free radical, thus restoring ‘peace in the neighborhood’. They do not become a free radical themselves.

How Are They Formed?

Free radicals are formed during the process of oxidation when two or more substances interact and an electron is lost. Oxygen doesn’t have to be involved but it usually is. Examples of oxidation are rust forming on exposed metal, or the browning of an avocado when it is cut and exposed to the air.

Free radicals can form as part of the normal metabolic processes and as part of the immune system response to pathogens. However, in today’s society we are exposed to more of them than ever before, due to the effects of stress, highly processed foods, alcohol, industrial pollution and cigarette smoke.

How Can This Benefit Me?

You need more than one particular antioxidant to get the job done! Different antioxidants target different groups of free radicals. The fact that there are so many polyphenol antioxidants in olive leaf extract means that they will target a large variety of free radicals.  Less free radicals means less cell and tissue damage; in other words, you have a healthier and more comfortable body.

Neutralizing the free radicals helps the appearance of skin. Have you noticed how people who smoke a lot have older looking skin?  It can also benefit all your organs, (including your heart), your blood vessels, and your joints, by reducing the inflammatory process; limiting tissue destruction; and allowing healing to occur more quickly.

The ORAC Measurement.

Do you known about ORAC?

Its full form Oxygen Radical Absorbance Capacity

Well, in case you haven’t…it’s a way of measuring the total antioxidant effect of a substance.  The higher the score, the better the product’s ability to neutralise free radicals. It’s an internationally recognised, in vitro, laboratory technique. The common way of expressing the results are μmol per gram, or per litre.

To give you an idea of how olive leaf extract compares with some well-known antioxidants, here are some results. The olive leaf extract (OLE) in this example is Envirolea ®  product from Olive Leaf Australia, which contains 12 key polyphenolic antioxidants. The information is taken from the Total Antioxidant Capacity graphs on their website.

Tested ‘Super-juice’ ORAC μmol/TE per Litre
Noni Juice 17,006
Mangosteen Juice 56,904
Acai & Guarana Juice 59,994
Goji Juice 81,000
High Strength fresh-leaf OLE 298,642
Tested Product ORAC μmol/TE per gram
Vitamin C 2,100
Grape Skin Extract 5,560
Green Tea Extract 5,937
Grape Seed Extract 6,250
High Strength fresh-leaf OLE 10,465

From this you can see that olive leaf extract is way out in front; being nearly four times as effective as the best of the super-juices; and over four times as good as vitamin C!

Olive Leaf Extract Benefit for Inflammation

Inflammation is a necessary part of healing. It is a programmed response that is the same for all body trauma, whether it comes from tissue damage (a cut or burn, for example); exposure to pathogens; or contact with irritants, (either internally or on the skin).

In acute inflammation, plasma and leukocytes (white blood cells) move to the affected area and the immune system kicks into gear to deal with the problem. It not only kills any microbes involved but also kills off the damaged cells so that new healthy cells can take their place.

With chronic inflammation, the situation is less helpful. It can even be life threatening. Tissue destruction and healing occur simultaneously as a result of an ongoing inflammatory process. The situation is never resolved and the immune system becomes more and more weakened over time.

Even with low-grade inflammation, this can have a huge impact on your health, increasing the risk of a heart attack and stroke; causing pain and stiffness in your joints; and leaving you more susceptible to disease.

Chronic inflammation is linked with health conditions like atherosclerosis. (see the next section), hay fever, rheumatoid arthritis and cancer.

Olive leaf extract reduces the inflammation; supports and strengthens your overworked immune system; and helps prevent destruction of healthy tissue by neutralizing free radicals.

Olive Leaf Extract Benefit for Heart Health

Olive leaf extract (OLE) has been found to:

Stimulate The Production Of Nitric Oxide (NO) in the walls of arteries. This gas normally signals the muscle cells in the arterial wall to relax, thus allowing the artery to expand. Constricted blood vessels are onecause of high blood pressure, because a narrowed tube increases the resistance to the flow of blood. This is one way that OLE is believed to lower blood pressure.

Cause Vasodilation Of The Arteries by supressing the L-type calcium channel. (One type of blood pressure medication is called a calcium channel blocker)

Inhibit Platelet Aggregation  (it stops them clumping together) by reducing Thromboxane A² production, thus making the blood less sticky and allowing the blood flow to increase.

Lower Cholesterol Levels:  It reduces the oxidation of low-density lipoprotein (LDL).  This ‘bad’ cholesterol causes plaque formation and hardening of the arteries’ (atherosclerosis), which reduces blood flow by narrowing or blocking the blood vessel. Olive leaf extract has been found to reduce overall cholesterol levels, and in particular to lower triglycerides and LDL levels. This is thought to be related to its ability to suppress inflammation.

Improved blood flow through the coronary arteries directly impacts on heart health, but the improvement is not limited to just this region. Keeping all the blood vessels healthy (relaxed, dilated and clear of cholesterol deposits) and the blood less sticky and faster-flowing, will allow for normal blood pressure and a healthy circulation. 

Olive Leaf Extract other Benefits

Benefits like weight loss; lowering of blood sugar; treatment of HIV; and anti-cancer effects are more recent discoveries. It is theoretically possible that these benefits (demonstrated by the small number of in vitro and in vivo studies) will be the same for humans as they were in the laboratory testing. It is encouraging to think that there may be a natural treatment for some of our worst diseases, like diabetes and cancer.

Weight Loss
Low level, chronic inflammation throughout the body (i.e systemically) has been linked with excess weight, particularly with fat deposits around the waist and abdomen. It is believed that the anti-inflammatory effect of OLE helps to inhibit fat storage.

Experiments with rats have shown promising results for weight loss. A Clinical Trial was commenced in July 2010, In Queensland, Australia. I’m still waiting to hear the results.

Since olive leaf extract Benefits reduces inflammation and assists the immune system in dealing with damaged tissues,
it follows that it may help in the reduction
of excess weight.

Lowering of Blood Sugar

Olive Leaf extract has been found to have
a hypoglycaemic effect on rats with drug-induced Diabetes. Blood glucose levels dropped and there was an improved uptake of glucose. It is too early to say whether this benefit can also be experienced by people, although there have been anecdotal reports to support this.

Cancer and HIV Treatment: There has been some preliminary research done, with positive results for breast cancer, liver and prostate cancer; and for HIV. There have also been numerous anecdotal reports of benefits for AIDS patients, dating back to 1996. A recent Japanese study showed that olive leaf slows the growth of leukaemia.

Radiation: There have also been some positive results with regard to OLE and x-ray radiation, leading to the thought that olive leaf extract may be beneficial against UV radiation from the sun, and nuclear radiation (in the case of a leak).

Gout: In Mediterranean regions, olive leaves are a traditional treatment for gout. A german study at the Uni of Leipzig showed that OLE inhibited the enzyme (xanthine oxidase) that contributes to gout. A drug commonly used to treat gout is allopurinol, which is a xanthine oxidase inhibitor.

Chelating Agent: Dr Richard Becker, of Bio Innovations, in one of his You Tube videos for his Your Health TV channel, reported that olive leaf extract is a natural chelating agent, that draws out mercury, and other toxic substances from the tissues. Olive leaf supplements were apparently given to the 911 workers who were exposed to the toxic rubble.

Now, you might be saying, this all sounds
great… in fact, it sounds fantastic!


After you read this article you think where is proof?

The short answer, is that the only proof that is ever relevant to you, are your own results, so your best bet is to give it a go. There are no known side effects and no established toxicity risk, so you have nothing to lose. A decent trial of olive leaf extract would be three months, but I suggest you check out my article on olive leaf extract dosage
That being said, there are plenty of research papers available for those who are keen to read them. I have included the details of some of them at the bottom of this article.
