Zoomed in picture of the oregano plant.

Whilst oregano is best known today as a culinary herb, the plant has a long and rich history dating back thousands of years, where it was first used for medicinal purposes.

And those health benefits of oregano oil remain just as relevant in the modern age, especially for people in search of natural remedies that can be used to treat and support a variety of conditions.

Oregano essential oil contains antibacterial, antifungal and anti-inflammatory properties that can play a crucial role in maintaining and improving our mental and physical wellbeing.

To give you a better idea of how, we delve into some of the oregano oil benefits, its history, uses and more.

What is oregano oil?

Sometimes referred to as “wild marjoram”, oregano oil is extracted via steam distillation from the leaves of the Origanum Vulgare (oregano) plant, which is native to the Mediterranean, Western Asia and Europe.

Whilst it can sometimes be grouped with other types of commercial wild marjoram oils , the main difference can be found in the fragrance.

Whereas oregano has a drier, woody and herbaceous scent, marjoram is sweeter, with a more delicate, citrusy aroma.

How does oregano oil work?

Oregano essential oil contains terpinene, sesquiterpene, flavonoids and phenolic compounds, which are believed to aid the delivery of a wide range of aromatherapeutic benefits.

extracted from oregano leaves is comprised of three main elements: Thymol, which acts as an antifungal agent; rosmarinic acid, which is a powerful antioxidant that can combat the threat of free radicals; and carvacrol, an antibacterial agent that is the most abundant in the plant.

The oil is usually applied topically by users to target fungi, bacteria and inflammation, although it can be diffused and food grade varieties can also be ingested.

3. Treating fungal yeast infections

Whilst yeast can be harmless, in cases where it overgrows it can result in a fungal infection.

Some forms of Candida yeasts occasionally appear on the skin, but there are instances where it can infect parts of the body, such as the genitals, mouth, internal organs and even blood.

looked into the effectiveness of oregano as an anti-fungal agent and found that it could be useful in combating the development of Candida infections.

4. Reducing skin inflammation

If allowed to progress, inflammation in the body can eventually trigger the immune system, causing it to attack healthy organs and tissue in the body.

Untreated inflammation can increase the risk of experiencing heart disease, cancer, diabetes and rheumatoid arthritis.

Some research has been conducted to test oregano’s anti-inflammatory properties, although additional studies are needed to fully assess its therapeutic potential.

This is because found several compounds in the oil have anti-inflammatory properties but could produce a toxic effect on some cells.

5. Anti-cancer properties

Carvacrol was used in various on cancer cells, with researchers learning that it was able to inhibit the growth of cancerous cells and also kill them off.

However, it must be noted that there have been no studies conducted on people, so whilst these test tube results are positive, much more detailed research is required before any link can be made to any form of cancer that exists in the human body.

6. Protecting the body against free radicals

examined the antioxidant content of 39 popular herbs and discovered that oregano contained the highest level of antioxidants.

Antioxidants play an important role in protecting the body against free radicals, which if left unchecked, can cause a lot of damage to the body.

For example, free radicals play a significant role in developing and ageing certain diseases, such as heart disease and cancer.

And when the body is exposed to some types of air pollutants, irritants and cigarette smoke, they can start to build up.

Like all essential oils, oregano oil is highly concentrated, so only a small amount is needed in comparison to fresh oregano, to benefit from its antioxidant properties.

However, using food grade varieties of the oil could prove beneficial as part of a healthy diet.

10. Relieving depression and stress

looked at the effects of using oregano on rats with depression, which produced some surprising results.

The treatment lasted for 14 days, after which researchers saw an improvement in rats that received oregano oil, with stress-related behaviour on the decline.

A conclusion was reached that oregano oil could be helpful in relieving stress-related behaviour.
