Olive Leaf Benefits

Olive leaf is the leaf of the olive tree (Olea europaea) was first used medicinally in Ancient Egypt. It is gaining recognition as a powerful defender against sickness and numerous scientific studies have been conducted to investigate the extracts beneficial properties. The reported benefits of olive leaf extract range from promoting increased energy and healthy blood pressure, to supporting the cardiovascular system and the immune system.

Olives are native to Asia Minor and Syria, but are cultivated in Mediterranean countries and also Chile, Peru and South Australia. Olive leaf was first used medicinally in Ancient Egypt and was a symbol of heavenly power. It was also used to mummify pharaohs. More recent knowledge of the olive leaf's medicinal properties dates back to the early 1800s when pulverised leaves were used in a drink to lower fevers. A few decades later, green olive leaves were used in tea as a treatment for malaria.

Modern health professionals first started using Olive Leaf extract in 1995 when it first became available and although a long-term perspective is not yet possible, initial results are very positive. It is emerging as a very promising and unique herb with multiple applications. It shows considerable therapeutic action against many common conditions. Olive leaf extract is gaining recognition as a powerful defender against sickness, and numerous scientific studies have been conducted to investigate the extract's beneficial properties. The reported benefits of olive leaf extract's range from promoting increased energy and healthy blood pressure, to supporting the cardiovascular system, and the immune system.

From research and clinical experience to date, we can say that supplemental olive leaf may be beneficial in the treatment for conditions caused by, or associated with, a virus, retrovirus, bacterium or protozoan. Among those treatable conditions are: influenza, the common cold, candida infections, meningitis, Epstein-Barr virus (EBV), encephalitis, herpes I and II, human herpes virus 6 and 7, shingles (Herpes zoster), HIV/ARC/AIDS, chronic fatigue, hepatitis B, pneumonia, tuberculosis, gonorrhea, malaria, dengue, severe diarrhea, and dental, ear, urinary tract and surgical infections.

Many people who live stressful lives or who may be particularly susceptible to colds and viruses may benefit from long-term use of olive leaf as a preventive agent. Some patients have expressed other unexpected benefits of olive leaf, including improved psoriasis, normalisation of heart beat irregularities, diminished cravings, less pain from hemorrhoids, toothaches and chronically achy joints.

In the early 1900s scientists isolated a bitter compound called oleuropein from olive leaf that was thought to give the olive tree its disease resistance.

In 1962 an Italian researcher recorded that Oleuropein had the ability to lower blood pressure in animals. It dilates the blood vessels so that blood may flow more easily throughout the system. Other European researchers validated that claim and also found it to increase blood flow in the coronary arteries, relieve arrhythmia and prevent intestinal muscle spasms. In the years to come, a Dutch researcher identified that a primary ingredient in oleuropein inhibited the growth of viruses, bacteria, fungi and parasites. This chemical was elenolic acid. Further European research determined this compound to have strong bactericidal, antiviral and antifungal capabilities. A safety study on calcium elenolate was tested with laboratory animals and published by the Upjohn pharmaceutical company in 1970. The study concluded that even in doses several hundred times higher than recommended; no toxic or other adverse side effects were discovered.

Research suggests that olive leaf may be a true anti-viral compound because it appears to selectively block an entire virus-specific system in the infected host. This appears to offer healing effects not addressed by pharmaceutical antibiotics. Olive leaf's broad killing power includes an ability to interfere with critical amino acid production for viruses; an ability to contain viral infection and/or spread by inactivating viruses by preventing virus shredding, budding or assembly at the cell membrane; the ability to directly penetrate infected cells and stop viral replication.

As an antioxidant, Olive leaf extract protects those blood vessels from damage, and has been shown to be effective in protecting the heart from coronary occlusion. When taken over an extended period of time, it is believed to reverse arteriosclerosis. Olive leaves are astringent and antiseptic. Both the leaves and the bark have valuable febrifuge qualities.

I am a type 2 diabetic and also suffered from heart disease. Recently I experienced a hyper thyroid and my readings went for the worse. My thyroid is now under control but my readings were still not always so good. I started boiling olive leaves and the results were astounding. I am now consuming olive leaf tea every day and I feel great!

as we reach middle age, using olive leaf extract as part of one's daily supplement routine makes a lot of sense - various kinds of stress can leave folks over 40 more susceptible to attacks by stealth pathogens - in other words, a person doesn't even have to be exposed to germs from another person, because the infectious organisms within their own body can reactivate and flare up during stressful periods - and they may not even cause full-blown illness but still cause enough inflammation to keep the body feeling worn out, affecting the thyroid, adrenals, etc...so olive leaf is a great natural weapon to wipe out these stealth pathogens which are often the root cause of so many other states of disease - i make sure i take my ole every day

I used a tincture at first, then found out that raw dried leaves are excellent for tea. I never sweeten it or add anything, I get about a 1/2 cup or so of leaves and grind them down to about 1/4 cup in a coffee grinder and I put some distilled water on the stove until it wants to simmer but doesn't quite simmer, then pour water over the ground material in a funnel fitted with a coffee filter. It is very bitter but tolerable and I hold a large gulp in the mouth for about 15-30sec before swallow. It creates, for me, a similar sensation that a shot of whiskey does, that tingly rush in the back of the neck and top of head. Of course it doesn't intoxicate me at all, its more like coffee, except that the energy you get from it doesn't come from a altered brain chemistry, but rather from the 400X more powerful ORAC than the 2nd best antioxidant known, purging my body of every toxin and pathogen known. I used to have tooth aches from bad teeth becoming infected. I used to get cold's seasonally. I used to be lethargic and have mental fog. I used to wake up groggy. I used to have very smelly sweat. I cannot even focus long enough to list all the benefits I have personally experienced from taking this herb in significant quantities. I have about 40 or so other herbs that I also revere greatly, but I think olive leaf has won most of my attention. I am surprised it is not illegal: i.e. hemp.

After watching a PBS program called Under our Skin,Health care nightmare. I was not only shocked over the wool being pulled (once again) over our eyes in America, I was frighten to see that I have had and still do many of the symptoms of Lyme disease,                                              which is progressively getting worse. Knowing that where I live I would hold no chance on getting help with the Medical Profession, and being somewhat of a herbalist I intend to take the God given route and make me up a tincture of Olive leaf, Thyme, Oregano and any and all other antibacterial herbs and take them for the rest of my life.
