Kill Germs Fast with Olive Leaf Extract!
The olive tree, a small evergreen native to Mediterranean regions, has been revered throughout history for its contribution to the culinary and healing arts. Its extracts have been used for thousands of years as a folk remedy for treating fevers, wounds, and infection, and for skin rashes and boils.1 The oil is symbolic of purity and goodness, the olive branch represents peace and prosperity, and Greek Olympians were crowned with a wreath of olive leaves.2
Now, scientific research has proven that the active ingredients in olive leaves do indeed have vast healing powers.
It's been well documented that the Mediterranean diet—rich in fruits, vegetables, grains and olive oil—is associated with a lower than average risk of coronary heart disease.
Olive Leaf Extract provides a number of powerful health benefits by:
- Protecting low density lipoprotein from oxidation3
- Inhibiting the growth of bacteria and viruses4 5
- Inhibiting platelet aggregation and production of thromboxane6 7
- Exerting a vasodilator effect8
- Providing potent antioxidant protection9 10 11 12
Olive Leaf's biochemical constituents
Olive Leaf has a variety of active constituents including several types of flavonoids (rutin, apigenin, luteolin).10

Antimicrobial activity
When unheated olives are brined in order to preserve them, oleuropein is converted into another chemical called elenolic acid. The same thing happens in the human body. Oleuropein breaks down to elolenic acid—in the form of calcium elenolate, a calcium salt—which has been found to be effective against dozens of different viruses.5 The elolenic acid interacts with a target pathogen at a receptor site—similar to how a key fits into a lock. The elolenic acid disrupts the replication of most pathogens, which allows the immune system to do its job of protecting the body from getting sick.
Elenolic acid has shown antibacterial actions against Lactobacilli and Staphylococcus aureus and Bacillus subtilus in a test tube study.4 This is particularly significant because Staph infections are becoming increasingly resistant to antibiotics. Olive Leaf Extract has also been shown to be effective against viruses, retroviruses, parasites, yeasts, protozoans, fungi, molds and other microbes and diseases in laboratory testing.
Based on successful animal studies, Olive Leaf Extract may be able to diminish the complications of diabetes in humans.
Inhibits transmission of HIV-1
One of the most exciting discoveries has been oleuropein's ability to inhibit acute infection and cell-to-cell transmission of HIV-1. It also has shown antiviral activity against viral haemorrhagic septicaemia rhabdovirus— a highly infectious viral disease that affects rainbow trout and other fish.13 The study's researchers believe that Olive Leaf Extract could be a potential source of promising natural antivirals used for humans.14
Supports a healthy cardiovascular system
It's been well documented that the Mediterranean diet—rich in fruits, vegetables, grains, and olive oil—is associated with a lower than average risk of coronary heart disease.2 Researchers believe that the natural antioxidants found in the diet—and especially in olive tree by-products—prevent cardiovascular disease by inhibiting the oxidation of low-density lipoprotein cholesterol (LDL), the "bad" cholesterol,3 which, in turn, retards the formation of atherosclerotic plaques. Olive Leaf Extract also plays a role in supporting normal blood pressure, and in reducing the risks associated with stroke by inhibiting the production of thromboxane—a factor in blood clotting.6 7
A study at the University of Granada, Spain, also found that an Olive Leaf Extract caused endothelium relaxation in the aorta in laboratory animals, which is significant because of its potential as a vasodilator to help prevent cardiovascular disease in humans.8
