Viral Infections

The Effect of Olive Leaf Extract

The ingredients of the olive leaf extract with their anti-viral properties help fight viruses such as flu and common cold as well as other viral infections such as herpes.

Influenza, Cold

Traditionally many people use olive leaf extract to treat viral diseases such as the common cold or flu. Year after year, medical research and studies scientifically establish the anti-viral properties of the extract.

In 2007, a review of studies dealt, among others, with the action of olive leaf extract on flu and common cold. In a study with animal models the extract reduced infectivity and inhibited the reproduction of viruses that cause colds, flu and lower respiratory tract infections. The study recommended further human clinical trials to validate these findings. (1)

The same study found that the extract stimulates phagocytosis – which can enhance the body’s response to a viral infection. (1)

The ingredients of olive leaves can relieve the symptoms of sore throat – possibly due to the reduction of inflammation and viral infection. (1)

In fact, medicinal compounds of olive leaf extracts may be useful in treating other viral infections, such as respiratory tract infections and rotavirus infections. (2) 

Herpes Simplex Virus Τype 1 (HSV-1)

Herpes is a virus that causes contagious wounds, usually around the mouth. The herpes simplex virus type 1 (HSV-1) causes groups of small blisters on and around the lips. Millions of people suffer every year from these blisters that develop into sores and can be extremely painful.

If one becomes infected, the HSV-1 virus remains in the body for the rest of its live, but blisters do not always appear. Usually, factors such as stress, a weakened immune system, strong sunlight, or hormonal changes can help the virus grow and cause inflammation (blisters).

The first symptom is usually an itchy feeling around the affected skin area, which turns into a burning sensation that becomes painful and even more painful as a blister develops. When the bubbles break, the liquid comes out and then a crust forms on top. They usually heal within 2 weeks.

Olive leaf extract is anti-viral and helps fight herpes. A 2016 study showed that the anti-viral and antimicrobial agents of olive leaf extract reduce the ability of the herpes virus to invade around cells and they offer quick relief.(3)

A 2007 study confirmed that liquid olive leaf extract has anti-viral action against the herpes simplex virus HSV-1. (4)

To treat herpes with olive leaf extract, pour one to two drops of cotton and place it on the wound. The extract may be used as a natural adjunct therapy to herpes along with regular treatment as prescribed by your doctor.

Viral Haemorrhagic Septicaemia (VHSV)

During lab tests, οlive leaf extract reduced the infectivity of the viral hemorrhagic sepsis virus VHSV. (5)

Human Immunodeficiency Virus (HIV)

Human immunodeficiency viruses (HIV) are two types of Lentivirus (a retrograde subgroup) that infect humans. Over time, they develop Acquired Immune Deficiency Syndrome (AIDS), a condition in which the progressive failure of the immune system allows life-threatening infections and cancers to thrive.

HIV infection activates genes that cause cell death (apoptosis), stress, and DNA damage. The use of olive leaf extract can reverse many such changes caused by HIV infection.

In addition, it can restore different cell signaling pathways from infected cells to other cells and inhibit cell-to-cell transmission, which is a critical step in the life cycle of a virus. (6)
