What Is Oregano Oil?

Oregano oil, also known as oil of oregano, is an essential oil that is extracted from the flowering tops and the leaves of the oregano plant, Origanum vulgare. It is believed to contain many active compounds which give it medicinal properties.

It is extracted through steam distillation or solvent extraction methods. Two main types exist. Oregano oil extract is a diluted form that can be used orally in humans, and oregano essential oil is a concentrated form for aromatherapy or external use.

More research is needed on the subject, but it is believed that oregano oil can be used for pain relief, to fight infections, manage tricky skin conditions, and aid in the maintenance of a healthy digestive system. It is also used as a flavoring in cooking and can be included in home-cooked recipes.

Potential Uses

Properties and potential uses of oregano oil for dogs include:
  • Antimicrobial: It has been suggested that oregano oil has antiviral, antifungal, and antibacterial properties meaning it could potentially aid in fighting conditions such as ear and skin infections.1
  • Antioxidants: Oregano oil contains thymol and carvacrol. These are potent antioxidants that are believed to protect cells from free radical damage.2 Carvacrol is thought to support beneficial gut bacteria and fight harmful organisms in the gastrointestinal tract.
  • Anti-inflammatory: There have been suggestions that some compounds in oregano oil have anti-inflammatory properties. They may aid in pain relief and the reduction of inflammation. This may give dogs suffering from allergies and other conditions some relief.

Oregano oil must be stored correctly to maintain its potency and prevent it from going bad. It is advised to store it at room temperature. It must be kept in a dark glass bottle, away from direct sunlight. Glass is preferable over plastic as plastics can leak chemicals into the oils. An airtight lid should always be used. A bottle with a screw cap and a dropper is ideal as this prevents leakage and minimizes air exposure. It must be kept in a cool dark place away from heat sources such as radiators. Do not store in humid rooms such as the bathroom.

It is possible to refrigerate oregano oil. This is thought to extend its shelf life, however, it will need to be taken from the fridge at least 12 hours before usage. This is to allow for it to heat up, so it is the right consistency to dispense. Always keep all essential oils well away from children and animals.

How Is Oregano Oil Given?

Oregano oil comes as an essential oil extract. It can be sold in a concentrated form. The concentration varies massively and can be from 2% to 50%. It can be bought as liquid drops; these are often mixed with carrier oils such as coconut oil or olive oil. Some companies make it into tablets or capsules.

In humans, oregano oil can be mixed with a carrier oil and applied topically. It can be given orally in a highly diluted form, and it can be diffused. Before considering any of the above methods, you must discuss safe and effective therapies with a vet.

Even if the essential oil has been diluted, it is still vital that only veterinary-recommended doses are used, based on your dog’s general health condition and weight.

What Happens If You Miss a Dose?

If you miss a dose of oregano oil, give the correct dose as soon as you remember. If it is close to the next scheduled dose, you can skip the missed dose and give the next one as planned. If you have any concerns about missed doses, consult a vet. It is never advised to give extra doses or double doses in any circumstance.

Potential Side Effects of Oregano Oil

As with all essential oils, there are potential side effects owners need to be aware of.

Even if the oil has been correctly diluted and the dose prescribed by a vet, some dogs can still experience adverse effects.

These can include:
  • Vomiting
  • Diarrhea
  • Skin irritation
  • Allergies

If you see any of the clinical signs mentioned or have any other concerns that your dog may be having a reaction, consult a vet immediately. Stop the use of the oil while you wait to hear from a vet.

There is a risk that oregano oil may interact with specific medications, this is why it is so important to discuss usage with a vet before starting it. If your dog has pre-existing health conditions this may also mean the use of oregano oil is contraindicated.

Undiluted oregano oil can be toxic for dogs. It can cause skin irritation and internal organ damage. It must never be used in an undiluted form.

Should I buy pure or diluted oregano oil?

Oregano oil in its pure form is very concentrated and has strong flavors. It is usually sold mixed with a carrier oil such as olive oil or coconut oil. Pure oregano oil is often better value for money but then needs to be diluted.

Is oregano oil organic?

Oregano oil can be sold in organic and non-organic forms. Good quality brands use organic oil. This will be obvious on the packaging but if you are unsure, you can ask the manufacturer.

Conclusion

Oregano oil has potentially promising health benefits for humans. However, there is limited research on the effectiveness and safety of oregano oil for dogs. It currently has no proven benefits, meaning there is no scientific evidence supporting its safety or effectiveness for treating any canine health issues.

Use must be with extreme caution and only ever under the instruction of a vet. Responsible use with proper guidance is important to avoid potentially catastrophic adverse effects.

  1. My dog has horrible yeast infection. We’ve tried the shot and pills to help her from itching to no avail. She has huge open sores. We’ve been to the vets. They say they have nothing else to treat her with. Could this help?

    1. Hi Jean. I’m so sorry to hear that your dog is going through this! It sounds really tough for both of you. While oil of oregano has some antifungal properties, it’s very potent and should only be used cautiously, especially on pets. It can be irritating to their skin and digestive system if not properly diluted. I would strongly recommend checking with your vet before trying it, as they might have other options or specialists they can refer you to. If the yeast infections are persistent, sometimes a more in-depth approach involving diet changes or a different type of treatment may be needed. I hope your pup gets some relief soon!

    2. Cefpodoxime proxetil has helped heal the open sores on my dogs paws from his excessive licking. Maybe ask your vet if this is something they recommend. We’ve tried everything and this is the only medication that is helping.

      1. Thank you for your thoughtful suggestion for Jean, Amber — that's very kind of you! Jean, since your current vet has said there's nothing more they can do, it might be worth seeking a second opinion, especially as there could still be another option to explore. If you'd like to talk it through with one of our vets, you're very welcome to book a time that works for you using this link: https://pangovet.com/schedule-appointment/.

    1. Dear Patricia,

      thank you for your question. Rather than focusing on a specific brand, it would be better to focus on the type and concentration of the oregano oil and which other oil was used as a carrier. Preferably you should look for organic oregano oil.

      Please just keep in mind, that it is important to consult this with your veterinarian before offering any treatment or remedy to your dog, as their condition needs to be considered to find the appropriate product and treatment.

      Best wishes
