12 Oregano Oil Benefits, Uses, and Remedies for Common Conditions

Jennifer is passionate about essential oils and uses them daily for health, wellness, and cleaning.

Oregano (origanum vulgare) is a well-known culinary herb that is typically dried and used in Mediterranean dishes. What many people are unaware of are the numerous health benefits of oregano oil. Oregano oil has been used for thousands of years for a variety of therapeutic purposes. This article discusses the 12 benefits and uses of oregano oil, as well as remedies for common health problems.

Risks and Side Effects

Oregano oil is extremely potent. If you take it internally, make sure to carefully read the directions on the bottle and never exceed the recommended dosage. Oregano oil is only considered safe to ingest in small amounts. Drinking too much oil at once or too frequently can be toxic to your liver. Never drink oregano oil without diluting it first.

If you are using oregano oil topically, don't forget to mix it with a carrier oil like coconut oil or olive oil to prevent skin irritation. It is always best to test it on a small area of your skin first to make sure you don't have a reaction.

Side effects of oregano oil include stomach upset, allergic reactions, and skin irritation. It is not recommended for pregnant or nursing women, as well as children.

How to Use Oregano Oil


You can drink oregano oil for colds, flu, digestive problems, bacterial infections, and viral infections by adding one or two drops to a glass of water or juice. Make sure to thoroughly mix it before drinking and avoid allowing the oil to come into contact with your lips. The oil and water will quickly separate, and the oil may burn if it comes into contact with your lips or skin.

Be aware that oregano oil has a very strong, unpleasant flavour that some people may find unbearable. It might even cause a burning sensation on the lips and inside the mouth. Oregano oil capsules are a good alternative if you want to avoid the awful taste.


Oregano oil can be used topically for fungal infections, warts, eczema, and other skin problems, as well as arthritis, and joint and muscle pain. Add a few drops of oregano oil to about half an ounce of carrier oil and apply it to the affected area. For arthritis, joint and muscle pain, massage the mixture into the area and repeat every half hour until the pain is gone.

Oregano oil can also be blended with other essential oils that are good natural pain relievers such as clove, frankincense, lavender, ginger, peppermint, copaiba, and yarrow.

If you take oregano oil internally, make sure to read the directions on the bottle carefully and never take more than the recommended amount. Oregano oil is only considered safe to ingest in small amounts. Never drink oregano oil without diluting it first. If you are using oregano oil topically, don't forget to mix it with a carrier oil like coconut oil or olive oil to prevent skin irritation.


1. Arthritis, Joint and Muscle Pain Remedy

Oregano oil has anti-inflammatory properties that can help relieve arthritis, joint, and muscle pain. Oregano oil has the ability to penetrate the skin and go deep into the joints to help relieve pain and improve mobility. Simply mix a few drops of oregano oil with a carrier oil and massage it into the affected area. You could also add some peppermint oil to the mix. The cooling sensation of peppermint oil can help to provide some immediate pain relief.

Note: Never apply the oregano oil directly to your skin without diluting it with a carrier oil first.

2. Psoriasis and Eczema Ointment

An oregano oil topical ointment can help relieve the symptoms of skin disorders such as psoriasis and eczema. Keep in mind that oregano oil is extremely potent and can cause skin irritation when applied directly to the skin. It is best to mix it with a carrier oil first like coconut oil or olive oil.

3. Gingivitis Treatment

The anti-microbial properties of oregano oil help to eradicate the germs that cause illnesses like gingivitis. Oregano oil can be applied topically to your teeth and gums to kill the bacteria and prevent any problems in the future. It is recommended to blend it with coconut oil, which is also thought to help treat periodontal diseases.

Note: Never apply oregano oil directly to your teeth and gums without diluting it with a carrier oil first.

4. Cold and Flu Remedy

Oregano oil is a fantastic natural remedy for colds and flu as it contains various compounds that boost your immune system. The most powerful component in oregano oil is carvacrol, which has anti-microbial properties and is known to break through the outer cell membrane of bad bacteria. This allows the bacteria to break down and be neutralized by the body's immune system.

Thymol is another active ingredient in oregano oil. Thymol has antifungal and antiseptic properties that have been shown to cleanse the respiratory system. Oregano oil also contains vitamins C, E, and rosmarinic acid, which help strengthen the immune system.

Note: Make sure to read the directions on the bottle carefully and never take more than the recommended amount. Oregano oil is only considered safe to ingest in small amounts.

5. Bronchitis Remedy

Bronchitis is a common condition that usually occurs after getting a common cold. It causes you to cough persistently and can take weeks to go away. Many people seek medical help and use antibiotics, which may be completely ineffective for some people.

Oregano oil can soothe your cough because it cuts through phlegm and mucus. It reduces inflammation in the respiratory tracks and stimulates the healing of the tissue. It also eliminates the virus or bacteria causing the cough, which can help prevent you from getting bronchitis in the first place.

6. Anti-Fungal for Yeast Infections

Oregano oil is a potent antifungal that can be used to treat and prevent fungal infections. Studies have shown that oregano oil inhibits the growth of Candida Albicans, which is the yeast responsible for causing yeast infections. Also with its antibacterial and anti-inflammatory properties, it's not a surprise that oregano oil would be effective in killing yeast overgrowth.

Use Oregano oil to treat a yeast infection by oral consumption. Start with 2 to 3 drops in a glass of water twice a day. You can gradually increase this up to 6 drops twice a day if necessary.

7. Toenail Fungus Treatment

Toenail fungus, like yeast infections, is caused by an imbalance of good and bad bacteria. Oregano oil inhibits and stops the growth of harmful bacteria. To kill the fungus, apply the oil topically to the affected area.

Changing your diet is usually the key to getting rid of toenail fungus. It is a good idea to try to eliminate sugar from your diet. Sugar is what yeast and bad bacteria feed on. Try to include more fibre, protein, and healthy fats in your diet. This diet, combined with oregano oil, should heal the condition and prevent it from recurring in the future.

8. Ringworm and Athlete's Foot Treatment

Oregano oil is a potent antifungal that can be used to treat fungal infections such as ringworm and athlete's foot. Apply a few drops of oregano oil mixed with coconut oil to the affected area several times a day. Taking oregano oil orally may also be effective in preventing the growth of fungal infections.

9. Cold Sore Minimizer

Cold sores can be extremely difficult to treat and can take a very long time to heal. When treating cold sores, oregano oil can be very effective. Using oregano oil in combination with a cream or ointment like Zilactin can significantly speed up the healing time of cold sores.

A good tip is to apply the oregano oil to the area as soon as you feel the cold sore starting, several times a day. This can be a great preventative measure and hopefully stop the cold sore from developing in the first place.


10. Oregano Oil for Your Pets

Oregano oil can also help pets with skin conditions (such as parasites or fungal infections). It may also be useful in treating arthritic symptoms in dogs. Make sure to use a small amount combined with carrier oil such as coconut or olive oil. Also, before applying it all over the animal, test it on a small area to ensure there is no skin reaction.

For a flea and tick eliminator, mix 5-6 drops of oregano oil in a gallon of water and use it as a final rinse after washing your pet. It is best to do this in a jug and shake the mixture thoroughly before pouring it on your pet. The oil will quickly separate from the water, so pour it on your pet right away to avoid irritating their skin.

Note: Never use oregano oil undiluted on your pet and make sure to test it on a small area first to make sure there are no reactions. Just like people, some animals are more sensitive to essential oils.

11. Natural Bug Repellent

Oregano oil is an excellent insect repellent. It is highly effective against mosquitoes, ticks, fleas, bedbugs, and lice. It's also a much safer alternative to bug sprays that contain DEET. Oregano can even be grown in your garden to act as a natural bug repellent around your home.

To make a bug spray with oregano oil, simply combine a few drops with water in a spray bottle. You could also add citronella oil and other essential oils like peppermint, rosemary, and lavender, which are also helpful for repelling insects.

12. Wart Killer

Warts usually appear on the hands and feet (palmer warts and plantar warts), but they can appear almost anywhere on the body. Warts can be extremely irritating and painful, and they can take months or even years to go away. Oregano oil can be very effective in burning off warts due to its high concentration of carvacrol. It is recommended to combine a few drops of oregano oil with a small amount of neem oil, which is also effective on warts.

What to Look For When Buying Oregano Oil

There are many essential oil companies to choose from, but not all of them provide the same quality at the same price. It's a good idea to do a little research before choosing an essential oil brand. It's important to make sure you are buying pure, therapeutic-grade oregano oil without any additives.

  • Be cautious of essential oils that are priced very low. They are most likely not pure or properly tested. Also be wary of some of the large, mass-produced essential oil brands that use multilevel marketing. These brands are typically way overpriced because they are really selling their brand.
  • Make sure the oil is sold in an amber or cobalt blue glass bottle. The dark glass protects the oil from heat and light damage.
  • Check the label for the scientific name of oregano oil, origanum vulgare. The label may even specify which part of the oregano plant was used and how the oil was extracted.
  • Make sure that the oregano oil you purchase is 100 percent pure. Looking at the ingredients on the bottle is a good way to check for this. It is not pure if the ingredients include anything other than origanum vulgare. Avoid anything that says essence oil or fragrance oil. These essential oils are not pure therapeutic essential oils.

Plant Therapy is one of the best essential oil brands for oregano oil in my experience. Their essential oils are high-quality, 100 percent therapeutic grade, and they go through multiple rounds of GC/MS testing by third-party experts. Plant Therapy essential oils are highly trusted and the prices are very affordable compared to some of the other leading essential oil brands.

I had no idea that oregano could be put to so many uses.

Jennifer C (author) from Ontario, Canada on November 14, 2018:

It does smell like oregano but it is quite strong. I will be honest oregano oil smells awful and it tastes awful too. It is hard to get down but the results are worth it.

Last year I woke in the middle of the night because my daughter was sick with the flu. I was starting to get terrible body aches and could feel that I was probably going to be sick by morning. I immediately drank 2 drops of oregano oil with water and and again the next day. It completely went away. I started feeling sick again the following day and took the oregano twice that day and it never returned. I've never had anything work so amazing!

This is an extensive list of health uses. I hadn’t been aware of any of them. Thanks for sharing this. Does it smell like oregano or is it unscented?
