Using Oil of Oregano for Sinus Infections and Chest Colds


You can use oregano oil as a natural treatment for sinus infections. Sinus infections are usually caused by a virus, and occasionally by bacterial infections.

According to the American College of Allergy, Asthma and Immunology (ACAAI), the most common treatments for sinus infections are antibiotics, nasal decongestants, topical steroids, saline washes and surgery.

While some of these treatments are very effective, they may come with unintended or unwanted side effects.

Antibiotics may eliminate the infection that caused the sinus infections, but until they take effect, they won’t reduce your symptoms. And nasal decongestants can shrink your swollen nasal passages, but some people can become dependent on them, or develop a condition where the nasal passages swell shut, called a rebound effect.


However, there are natural treatments that may be just as effective.

Studies have shown that carvacrol, a monoterpenoid found in oregano, thyme, bergamot and other plant species, has antimicrobial properties.

Additional research has looked at the antiviral properties of oil of oregano against different human and animal viruses.  Researchers found carvacrol has high anti-viral activity against a number of virus.


How to Take Oil of Oregano for Sinus Infections, Sore Throats and Colds


In our article, Guide to Taking Oil of Oregano by Mouth, we looked at how you take the oil orally by capsules or in the liquid droplet form.

You can inhale the oil as a steam vapor through an essential oil diffuser/humidifier or you can topically apply it to your skin.

When it comes to treating sinus infections, the most effective way is to either steam inhale the vapors through a humidifier or ingest the soft gel capsules.

Due to the nutritional supplement nature of oregano oils, we cannot suggest any specific dosage recommendations.

Please remember to consult with your doctor before using any nutritional supplement.


Many people have successfully used oil of oregano to treat their own sinus infections and other upper respiratory tract issues. 

The following are testimonials from people who’ve tried using oregano oil:

Oregano Oil Cleared my Sinus Infection!

by C. Etris (Cincinnati, Ohio)

I have heard many times over the years about taking oil of oregano to clear up sinus infections. I get infections every year because of constant sinusitis and allergies. I also have a bad immune system. When I woke up one day and had a sinus infection getting worse as the day went on, I then decided to try oil of oregano capsules sold at the local nutrition store.

The capsules were 60 mg. I found out how much to take on average for a sinus infection. So, I took seven pills a day for three days and my infection was gone. I always take vitamin C and zinc but that did not stop the infection. The oil of oregano capsules did the job. Some people take up to 600 mg. in a day for infections but I did not need to.


Using Oil of Oregano and Chest Colds

by Marge L. (Boise, ID)

I find Oil of Oregano is a great natural cure for chest colds. At the first sign of a cold I take a couple capsules of Oil of Oregano every day. It doesn’t relieve the symptoms immediately, but I found that this essential oil seems to shorten the duration and lessens the intensity of my cold. I found that oil of oregano seems to work better than using echinacea or other herbal treatments.


Chronic Sinus Infection and Oil of Oregano Experience

by Mary Barnard (St. Vincent and the Grenadines)

Oil of Oregano helped cure my business partner’s chronic sinus infection. My business partner had a sinus infection so bad his doctor used his x-rays as a teaching tool. He had several operations, but each time the condition returned.

I imported a gallon of pure oil of oregano from Turkey to share with my extensive family. I mixed small quantities at a time in a ratio of 4 to 1.

After taking two teaspoons initially daily for about a month his sinuses are completely cured. He no longer needs the antibiotics he was taking at lest 8 times a year and the pain killers he took daily. All these drugs had played havoc with his stomach and he had lost 40 lbs.

Today, a year and a half later, he only had one flare-up and that was when he had been off the oregano maintenance dose of one teaspoon daily for two weeks.


Curing Strep Throat with Oil of Oregano

by Aimee (Texas, USA)

I got rid of strep throat twice in myself and once in my 7 yr old daughter using Oregano Oil in the proper doses 3x a day for 10 days. I had to put the oil in capsules so we could stand it! I also had an infected wound that didn’t get better with triple antibiotic ointment. I mixed the already diluted Oregano Oil I had with coconut oil and applied a few times a day with a bandage. The pain went away within minutes and the infection was gone within a few days.
