Pathogen destroyers offer a complementary and alternative means of assisting the immune system. While they do not act the same way as immune boosters as they don't build the body’s immune functions, they do help free up the immune function of the body. They do this by destroying the pathogens that would otherwise keep the immune system preoccupied. They function similarly to antivirals and antibiotics, with the difference being that they are natural.

Olive Leaf Extract vs Oil of Oregano

Olive Leaf Extract

Extract from olive leaf has long since been a staple in traditional medicine. Sourced from the olive tree leaves, they are known for a bevy of benefits. Research reveals that the extract’s main component called oleuropein has antimicrobial, antibacterial, antioxidant, immune-stimulating and anti-inflammatory properties.

Throughout history, extract from olive leaf has been a popular treatment and prevention for infections including influenza, common cold, shingles urinary tract infection, and Candidiasis. It is also used for treating allergies, diarrhea, and even such diseases as chronic fatigue, Alzheimer’s, osteoporosis and osteoarthritis.

The extract is also known for its antiviral properties, making it quite useful in holistic medicinal practice for the treatment of certain viruses. Olive leaf extract has also shown in a laboratory setting to be effective in fighting mononucleosis, rotavirus, and herpes. It might also bring about positive results when used against HIV and influenza.

Admittedly, the research may be limited only to cultures of cells, the benefits of the extract may have yet to be proven in actual human studies. Still, there is some solid anecdotal evidence that supports the effectiveness of the substance in the treatment of cold sores.

Oil of Oregano

Oil of oregano is extracted from the shoots and leaves of the plant. Known for its scientific name Origanum vulgare, the flowering plant comes from the same family that mint belongs to. Usually, it is used for flavoring food.

The plant originated in Europe although today, it can be found growing in almost every part of the world.

The Romans and the Greeks were the first to tap into its medicinal values. The plant is named from the Greek word “ganos” which means delight or joy and “oros” which means mountain.

The oil is extracted from the air-dried shoots and leaves. Once they have completely dried, the oil gets extracted. Using a process called steam distillation, the oil is then concentrated.

It’s notable that the oil is comprised of terpenes, terpenoids, and phenols. These are known for their antioxidant properties. They are also often credited for the distinct fragrance of the oregano plant.

  • Carvacrol - Considered as the phenol of highest abundance in oregano oil, it is known for having the ability to inhibit growth of some bacteria.
  • Thymol -Known for its natural antifungal property, it’s also known for its capacity to protect the body against toxins as well as in supporting the immune system.
  • Rosmarinic Acid -Another powerful antioxidant, it can help protect the body against the damage that free radicals cause.

Due to the abundance of carvacrol in oregano oil, it may be effective against fighting certain bacteria types.

For instance, a common bacteria is Staphylococcus, which is known for causing staph infection. Some of the strains of these bacteria can sometimes naturally occur in the human body. However, when it grows at an unprecedented pace, it may cause symptoms that are quite bothersome to the person.

Research reveals that carvacrol can be quite effective in the elimination of Staphylococcus epidermidis and Staphylococcus aureus— two of the most known causes of the infection.

Rubbing oregano oil on the skin or taking it as a supplement might help one harness its antibacterial properties.


Considering that research is limited as far as oregano oil and olive leaf extract go, it may still be too premature to recommend these supplements for treating any condition.

It’s important to remember that delaying or avoiding standard care or choosing to self-treat a condition may bring about serious consequences later on. If you’re pondering the idea of using these supplements for whatever health purposes, see to it first that you consult your doctor for proper guidance.
