Description of Oleuropein

Oleuropein is the active ingredient or glucoside, found in green olives and olive leaf. Olive leaf is found on the olive tree. Another active ingredient found in olive leaf is hydroxytyrosol, polyphenols, flavonoids, and Oleocanthal. Oleuropein and olive oil, extracted from green olives and olive leaves, are known in alternative medicine for its medicinal benefits.

Scientists began to evaluate the benefits of oleuropein, olive leaf, and olive oil. These studies began when scientists noticed that individuals in the Mediterranean consistently showed a lower occurrence of heart disease and cancers. The cancers with the lowest incidence were prostate and colon cancers. Scientists attributed this finding to the diet consisting of mostly fruits, vegetables, peas and fish. But more importantly, it is attributed to olive oil comprising the majority of the fat content within the diet.
Oleuropein Uses
Oleuropein or olive oil is known for its anti-aging effects, its antifungal properties, its anti-infllamatory properties, its antibiotic properties and its immunostimulators. Olive leaf extracts have also been known to lower blood pressure. Scientists discovered, in an international study, that olive leaf extract contained twice the antioxidants of green tea extract and 400 percent higher than Vitamin C.

Individuals, who practice alternative medicine, use olive leaf or Oleuropein for the following purposes:

  • Natural pathogens killer: It kills pathogens by preventing pathogens from replicating.
  • Colds
  • Flus
  • Yeast Infections
  • Heart Disease
  • Lowering Bad Cholesterol or Low Density Lipoproteins (LDL)
  • Lowers Blood Pressure
  • Increases Blood Flow
  • Treats Epstein-Barr Disease
  • Treats Shingles
  • Treats Herpes

Because of its remarkable antioxidant properties, oleuropein protects the body from free radicals. When free radicals undergo the oxidation process, they may cause cellular damage if they exist in the body in excess for extended periods of time. Free radicals are highly reactive. Therefore, antioxidants must be introduced to prevent development of diseases such as cancer and other diseases.

Oleuropein is a polyphenol extracted from the leaves, bark, root, and fruit of the olive tree. The olive tree contains agents that make it highly resistant to insect damage and other diseases. Oleuropein is also classified as an iridoid.

    I have been researching olive leaf extract, and have run into a few problems. On a couple sites it says that olive leaf side effects are just your body ridding itself of toxins (headache, nausea, body aches, etc). But on other sites, it says that if you feel these side effects, to immediately stop taking olive leaf extract and see your doctor. Which one is it!!! I want my family and myself to live healthier and try natural remedies, but I cannot ever get a straight answer on safety!

      Dear Nicole

      As we are producing olive oil and have been using olive oil in almost everything, I can assure you that olive oil and everything related to it is very very safe. You do not have to worry. You cannot eat one teaspoon of salt in a salad plate, so you cannot drink a glass of oil like water. Moral: balance the intake of anything.

      Regards and sorry for my English if not perfect.

    I love taking herbs to heal my body. Have been for years… When I get a “cold” U prefer Olive leaf to Echinacea.. Echinacea, is only a combat to bacteria,, but Olive Leaf is better to me because it helps with a virus as well.
    Great when you aren’t sure whether or not your cold is bacterial infection or viral infection..

  • Reply Jana

    While I was taking oleuropein capsules I felt nausea every day for several minutes or even hours, even vomitting twice which normally does not happen to me. I had detoxified may times before and never felt any side effects so this probably disagrees somehow with my body – not sure who can explain that.

    I’ve been trying to figure out a way to get rid of hsv2 for good….. & I came across an article naming this product as they answer for that. I’ve been taking the capsules since Monday, bur does this really work for the virus? Does it kill the virus completely? Like, will I EVER have to worry about another outbreak? How long does it take to get rid of the virus? Do I have to swallow the pill whole or can I dump the powder in water & drink it like that? How many pills should I take a day? Sorry for all the questions, but I need answers….. I’m tired of having to have secrets!

    —-Please help me

  • Reply Mimiofthreebeautifulgrans


    I have been researching this product and came across the answers you’re looking for. You’re to take one capsule three times a day, best at mealtime. The article also states if you are feeling under the weather you should take one capsule every 4-6 hours.

    Oleuropein is supposed to be great in fighting a low immune system,
    High blood pressure, the Herpesviruses (both 1-2). It also makes a statement that if used for that type of infection listed above that you can get the powder form and make a mix to put directly onto your area where needed.
    Just please make sure you do a drug interaction search to avoid any serious side affects.
    Hope this helps!!!!!!!!!

      I new someone who had hsv2 and she was devastated. I talked to her about it and did some research and found olive leaf, I told her to take 1500mg a day (500mg at 8am 500mg at 2pm and 500mg at 8pm). She did this for 3 months and after the 3 months she was all clear. The product she used is was not cheap since a bottle will last 2 weeks but at least you can be free from it, good luck.

    I have read somewhere that Oleuropein contents in the olive leaf extracts dont have any side effects. But some people could experience herxheimers reaction, usually lasts for around 5-7 days, if they have a high viral load or a lot of pathogens in their body. Like feeling queasy and even cause mild diarrhea, which is simply a “die-off” reaction. Because OLE is such a powerful detoxifier.
