Introduction to Olive leaf extract benefits

Olive oil is has been known and used to prevent heart attack and stroke (cardiovascular disease), breast cancer, colorectal cancer, rheumatoid arthritis, and migraine headache. But Olive leaf extract comes from the leaves of olive tree, and is much different from Olive Oil. the olive leaf contains phenolics such as oleuropein, It has shown that it has protective effects against LDL oxidation also  benefits glucose metabolism for diabetes and skin health. Olive leaf is used as immune system boost for treating viral, bacterial, and other infections including influenza, swine flu, herpes, shingles, HIV/ARC/AIDS, and hepatitis B, pneumonia; chronic fatigue: tuberculosis (TB); gonorrhea; fever; malaria; dengue and infections in the teeth, ears, and urinary tract, and infections following surgery. Some Other also use it for high blood pressure, diabetes, hay fever, improving kidney and digestive function. Olive leaf kills and /or resists the multiplication of viruses, bacteria, yeasts, fungi, and other parasites in body. The olive leaf extract differ from immune boosters in that immune boosters tha stimulate your immune system to destroy disease which still requires your own energy. Olive leaf extract mainly does the work for you. it is not a supplementary for immune system it is like a parallel procedure.

Cancer and Olive leaf (extracts)

The Mediterranean diet which includes olive is renowned for its ability to reduce the risk of cancer as some researches say.  While numerous aspects of the diet contribute to this risk reduction, there’s growing evidence that olive oil and leaf extract contains phenolics such as oleuropein that are key components of the diet’s anti-cancer effects. Oleuropein and olive leaf extracts have numerous other mechanisms of action against cancer: They can prevent inflammation,  inflammation is another major promoter of tumor growth and olive leaf extracts are strong in fighting  inflammations.
In breast cancer cells specifically, oleuropein reduces malignant cells’ ability to respond to estrogen, the female hormone that many breast cancer cells depend on for their survival. Oleuropein stops production growth factor and the “protein-melting” enzymes that cancer cells need in order to invade healthy tissues.

Neuroprotection of Olive leaf (extracts)

Olive extracts help protect the brain neural system from the destruction brought on by age-related degenerative conditions such as Alzheimer’s and Parkinson’s diseases.  Olive extracts suppress the inflammations and reduce the damage done by oxidative stress in body cells, we did mention what oxidative stress is and how antioxidants tend to stop it from damaging our body, read more about that in our full article about Antioxidants.
Researchers found that if  the possible stroke patients be pre-treated by olive  extracts they can greatly reduce the damage after stroke. cause basically after a normal blood flow comes back after the stroke the damage gets worse. But olive extracts has shown that they change the atmosphere of the system so the come back is not that dangerous. Microscopic examination of brain tissue showed up to a 55% decrease in the volume of dying brain tissue after strokes that were pre-treated by olive extracts. Brain damages and inflammations in brain all lead to more dying neurons and cells that will lead to creating more tangles. tangles are one of the two main reasons and causes in brain aging. so Olive extracts generally work as a nice anti-age supplement.

POLYPHENOLIC ANTIOXIDANTS & Olive leaf (extracts)

Polyphenolic antioxidants can help to slow down ageing by reducing cell degradation and assist in the prevention of a number of degenerative diseases. Polyphenolic antioxidants are best known in the scientific and medical communities for their ability to neutralize free radicals. The most studied polyphenolic antioxidants in Olive Leaf.
