6 Oregano Oil Benefits: A Comprehensive Guide to Wellness

Discover the amazing oregano oil benefits for your overall wellness in this comprehensive guide. From boosting immunity to fighting off infections, oregano oil has a wide range of health benefits

Oregano oil is derived from the leaves and flowers of the oregano plant, and it is known for its antibacterial, antiviral, and antioxidant properties. It has been used in traditional medicine to treat a wide range of ailments, from colds and flu to digestive issues and skin conditions.

What is oregano oil?

Botanically recognized as Origanum vulgare, oregano is a blooming plant that belongs to the same family as mint, frequently utilized as an herb to add flavor to dishes.

Oregano essential oil comes from air-drying the plant’s leaves and shoots, extracting and concentrating the oil through steam distillation.

Blend oregano essential oil with a carrier oil for topical use, but avoid oral consumption.

Oregano oil extract can be created using various extraction techniques, such as carbon dioxide or alcohol.
It is easily accessible as a supplement and is commonly available in pill or capsule form.

Oregano Oil Benefits

1. Rich in Antioxidants

Oregano, available in fresh or dried form, possesses strong antioxidant qualities.
Antioxidants are compounds that could help stabilize free radicals, potentially protecting cells in the body from damage.

Oregano oil contains high levels of antioxidants such as carvacrol, thymol, and octacosanol, which seem to play a key role in the herb’s numerous health advantages.

A study conducted in a laboratory discovered that applying oregano extract to cells before hydrogen peroxide exposure helped neutralize the oxidative stress induced by the hydrogen peroxide.

Oxidative stress happens when there’s an excess of unstable free radicals in the body, and the antioxidants are insufficient to eliminate them, potentially causing aging and ongoing inflammation.

2. Assist in reducing inflammation.

Oil of oregano and oregano essential oil both demonstrate anti-inflammatory properties.

A study involving rats discovered that applying oregano extract topically effectively decreased inflammation triggered by Propionibacterium acnes, a bacterium known to induce skin inflammation and acne.

Another research discovered that carvacrol, the primary antioxidant in oregano, decreased inflammation and blood cholesterol levels in mice that were given a high-fat diet.

Moreover, research conducted on human skin cells revealed that oregano essential oil could aid in combating inflammation, enhancing the healing of wounds, bolstering the immune system, and potentially guarding against cancer.

It’s worth noting that oregano essential oil might be harmful to certain cells.
More research involving humans is necessary before suggesting it as a regular remedy for reducing inflammation.

3. Antibacterial Properties

Oregano oil, with its high carvacrol content, displays potential in treating bacterial infections through topical application.

In a study conducted in 2021, it was discovered that oregano oil displayed notable antibacterial properties against 11 strains of bacteria resistant to various antibiotics.

Additional research indicates that oregano essential oil could provide defense against various bacteria strains linked to food poisoning and dental cavities.

For safety reasons and potential toxicity, it’s best to avoid ingesting oregano essential oil unless advised by a healthcare professional.

4. May Enhance Respiratory Function

Oregano traditionally treats respiratory issues like asthma, coughs, and bronchitis in natural medicine.

Two randomized control trials discovered that carvacrol supplements enhanced inflammation, lung function, and respiratory symptoms among individuals suffering from lung damage and asthma.

More research is still needed to verify if oil of oregano can elicit similar outcomes.

5. Enhance Digestive Health

Historically, oil of oregano was utilized to address digestive issues such as indigestion, diarrhea, and upset stomach.

Though research on humans is scarce, there is some indication that oregano oil could help prevent or eliminate harmful gut bacteria.

An observational study discovered that herbal remedies, such as a product with oregano, might work just as well as antibiotics for addressing small intestine bacterial overgrowth (SIBO).

SIBO, a common condition, results in abdominal pain, gas, bloating, and diarrhea from excessive bacterial growth in the small intestine.

Oregano’s believed gut health benefits stem from its carvacrol and thymol content, which possess anti-inflammatory, antibacterial, and antioxidative properties.

6. Anti-Fungal Properties

Oregano can aid in combating fungal infections.

In a study conducted in 2022 using test tubes, it was discovered that oregano essential oil showed efficacy in combating Candida albicans, a form of yeast (fungus).

When candida overgrows, it can lead to thrush and yeast infections, and in extreme situations, it can result in infections in the bloodstream, heart, brain, or kidneys.

An excess of candida could exacerbate inflammatory bowel conditions such as Crohn’s disease and ulcerative colitis.

Furthermore, a study conducted in 2020 on a group of 20 patients revealed that the use of a topical antifungal with oregano as an ingredient led to an improvement in nail fungus.

Nevertheless, the antifungal formulation consisted of various other components, posing a challenge in isolating the specific effects of oregano oil on achieving similar outcomes.
