Oil of Oregano for Sinus Infections

Oil of oregano is an effective natural treatment for sinus infection and a wide range of other conditions. While many herbs worldwide possess medicinal properties, oregano is a healing marvel with antibacterial and antioxidant properties. Natural remedies are more beneficial than mainstream treatments for many ailments (when used appropriately) as the body does not usually become resistant to herbal cures.

Oil of Oregano Remedy for Sinus Infections

In contrast, oregano oil is a safe, natural home remedy that effectively treats sinus infection without altering the body's natural balance. Oregano has been used as an essential medicinal herb for over 2,000 years. It is grown in the Mediterranean region (and in backyards and sunny windowsills almost everywhere!) and has increased in culinary and medicinal use in recent years. Oregano contains specific compounds that make it an effective natural health treatment.

How It Works

Oregano has very potent antibacterial and antioxidant properties. On a gram per gram comparison, oregano has 42 times more antioxidant abilities than apples. When oregano oil is used as an alternative sinus infection treatment, it eliminates the underlying cause of the condition. The oil also possesses specific anti-inflammatory properties, relieving swelling in the nasal cavities, and facilitating a freer flow of mucus in the nasal passages.


Treating sinus conditions using oregano oil is relatively straightforward.

One treatment method reported by a few readers requires just a drop or two of oregano oil beneath the tongue. However, as one reader warns, oregano oil must be diluted with another oil like coconut or olive before being placed under the tongue to avoid burning your mouth. (Anyone who finds the taste objectionable can put the oil into an empty gel capsule.)

An additional option involves bringing a pot of water to steam (not boiling), placing a couple of drops of oregano oil in the water, and draping a cloth or towel over the head and neck while standing over the pot to breathe in the vapors. Either method is effective.

Many individuals suffer from recurring nasal congestion and sinus infection issues. Oregano oil is one remedy that can be used regularly with few to no side effects. Regular dosing with oregano oil clears the sinuses and restores health to the whole nasal system.

I read about oregano JUICE for sinus infection here years ago. I got an infection that simply wouldn't budge. Very distressing. Thick obstructive post nasal drainage discharge pressing on my swallowing mechanism, waking in the middle of the night gasping with completely blocked airways. I am a huge proponent of oregano for infections and viruses but this thing wasn't moving an inch with all the capsules and oil I was throwing at it.

Then I remembered about the JUICE option and thought well hell, if it doesn't work then I'll just have to knuckle under and go the antibiotic route. I ordered a couple of bottles of juice, and last night they arrived. I diluted 4 capfuls in 250ml distilled water and ran it through my sinuses with a neti pot.

Within an hour – ONE HOUR – I noticed there was no more pressure on my swallowing mechanism. I went to sleep normally and was not disturbed once overnight. In the morning, back of my throat still clear and “dry”. i'm clearing a rhinovirus right now and there was some disturbance later in the AM but I ran the oregano juice through again at noon, and as I type this, my sinuses feel clearer and lighter than they have in many many weeks. I also use the juice in dilution in my waterpik to gently disinfect my gumline. This stuff is truly God's gift. Now with the first two cases of confirmed 2019NCoV only twenty minutes from where I live, I am armed to the teeth with oregano.

Stay well, friends.

I have had sinus infections for 8yrs straight!! Like clock work had to go to doctors for antibiotics. The problem with that is it was causing Year infections due to killing all good bacteria in my body as well. Finally I went to the health food store in dire straights, all stuffed up and asked the naturalist what to do? She said put 3 drops of oregano oil in a shot glass of warm water and in 3 days you will feel a ton better and won't need that antibiotic! Sooooo thankful! I also use to be on Zyrtec every day of my life because I suffered with postnasal and vertigo. Ever since I have been taking oregano oil, I am medication free. If I start to feel any symptoms, I may take a shot or two a day and it takes away all symptoms. During cold and flu season, I take one shot every day or every other day! Amazing stuff!!

I take the time to write this review in hopes it will help someone like me. Oregano Oil sounded hokey to me, but I was DESPERATE, dealing with chronic sinus disease for almost 2 years, extreme pain, pressure in my head on a daily basis that would turn into severe migraines from all the pressure in my head. Dizzy constantly, not able to work & look at my computer w/o getting a migraine. Finally had sinus surgery in hopes it would cure me, but it didn't. Taking daily notes & diaries to log every food, allergy med, etc. I was taking & googling every possible remedy I could think of, I came across Oregano Oil. Started 3 drops with apple & lemon juice, twice a day. I noticed changes right away but didn't want to get my hopes up. After about a week or so, I had NO symptoms!!!! I was thinking it was a fluke & for sure would come right back. NOPE, I got my life back!!!! I still have recurrent infections I can feel coming up, if that happens I make sure to start another Oregano Oil routine (having one right now :( But I recommend it to anyone I know & I tell everyone. Including my doctors who laugh it off.

Elizabeth; I heard there were so many offerings of Oregano Oil, it leads to confusion as there is a glut of copycats out there to just make a buck...which specific one did you have your experience with?

Will a oregano oil pill also work? I just started taking them. Chiropractor said it should help kill the bad bacteria in my belly.

Yes, the pills work fine. Read online reviews on Amazon, there are different strengths and qualities - but for those who hate the taste or the burning sensation, pills are the way to go. I use them for myself all the time, and even my kids sometimes (at a lower dose) when they have ear aches or sinus infections.

I have sinus infections all the time. My sister told me about oil of oregano. I took 2 capsules each in the morning and 1 at night. I did this for 7 days and my infection went away.

I've had profound good luck with Oil of Oregano helping to prevent sinus infections. I was getting the sinus infections very often. I take the 00 tablets whenever I'm around young children, fly in an airplane or any other situation I formally would get a sinus infection.

Since doing this, I have not gotten a sinus infection. I think it is an excellent preventative and MIGHT work for a mild sinus infection. Of course, one must see a doctor for any serious infection.

Just take in an empty capsule. Read my post about clove oil. Greater quantity of oil is required when swallowed than when simply held in the mouth. Inhalation puts oil molecules directly into the blood stream through the alveoli of the lungs, as well directly to the brain through the olfactory nerves which connect to the central brain. French school of aromatherapy says the best way to optimize the benefits of EO is to be open to administering them by any and all pathways, by nose, skin, mouth, intestines (suppositories), rectum, and or vagina, depending on the situation. Either way you apply it will immediately reach your blood due to small size of its molecules. Try to apply on the soles of your feet or a throat, you will immediately taste it in your mouth. Read about safety measures in my post about clove oil. Oils are smarter than antibiotics. They have homeostatic intelligence. Myrtle oil for example can stimulate an increase or decrease in thyroid activity depending on person's condition.

Get Inhaler Maholda, a clear glass inhaler and inhale oils. It has an attachment to inhale through nose. This cheap medical device is worth million times more than it cost. Different oils for differrent purposes. Oils cross blood brain barrier and can be used for neurological or any kind of health issues. Get free book on butterflyexpress oils for guidance. The inhaler is very cheap, don't overpay. It is invented by a german scientist and maybe found in russian/ukranian shops. It cost 29 grivna in Ukraine. About $2-3

I would also add Quercetin and take it for not less than 6 months. NOW brand with bromelain is a good one. Address guts health where body immunity begins. Read Patient heals thyself book, which on a surface has nothing to do with your problem. But only on a surface. "Garden of life " digestive health supplements are excellent. You will know what to take after reading this book. Meantime Use inhaler Mahold. Essential oils are God sent miracles.. or God's love manifest in molecules ( as david stewart named his book)

I don't usually write posts on websites but for this, I NEED to.

For many years, I've had terrible sinus infections -- like clock work! : in-between Sep-Oct, Dec-Jan, Mar-Apr. With out fail! For whatever reason, when there is a change of temperature or season, my nasal passages decide to fill with green mucus and cause my body to think it has a fever...not fun!

So las December my girlfriend introduced me to oil of oregano pills, recommended by one of her was life altering.

I started taking these pills a week or two before the known months of sinus issues and bam!!!!!! Problem solved!! It has eliminated, no, eradicated my sinus issues completely along with my allergies. And get this, any time I feel my asthma creeping up, instead of taking the inhaler, I drink one of the pills and 3 hours laters I start coughing up white mucus and asthma gone!!!!

I only take the pills 4-7 days straight out of the month and it has helped my tremendously.

PLEASE PLEASE PLEASE, if you suffer from sinus pain/congestion, give it a try, at least for a will thank yourself!!

I too have had good fortune with Oil of Oregano. I've had many sinus infections over the last three years. I would get them very easily...especially when around children. I probably got one every three months. I now take two O of O tablets a day when I'm around children, flying or if I have even the tiniest symptom. And, so far, so good. I've also observed it like a miracle stop a cold in it's tracks with friends and relatives. I believe it is a blessing.

Yes!!! This Oregano Oil is THE BEST!! I have been suffering from sinus infections for about 15 years and had 4 sinus surgeries. I have tried probably every type of Antibiotic out there even hospitalized on a IV Antibiotic, nothing seemed to work. It is a horrible experience. I turned to the Oregano Oil thanks to a good friend. This stuff after 10 days has completely rid the underlying condition that was causing these miserable infections. Thank you Oregano for letting me live infection free. Anyone who may experience the same problem or similiar problems, best thing it is NATURAL.

First of all, I commend you on giving God the Glory! You will be blessed. I, like so many others, have suffered with sinusitis and sinus infections all my life and I'm concerned and getting weary of so many antibiotics I've used (sometimes 2 or 3 times a year). Recently, I was given a bottle of oregano spirits, using a dropperful in a pot of steaming water. It really helped (along with the saline neti-pot solution)! I'm still considering the sinus surgery for a deviated septum, etc. Thank you for your post!

I had this terrible sinus infection. It would not budge, I even did garlic water neti pot rinse and it helped but, it still remained( it burns!! ). Finally I gave into buying the expensive oregano oil (I'm of low means). I bought Oreganol Oregano oil capsules regular strength at my health food store like $30 dollars for like 30 pills ( the capsules are so tiny) something like that. I was that desperate having tried many things with improvement but not full success. I worked!! I took 3 a day, till I finished the whole bottle, ( if you can take more then go for it, im sure you will see quicker results, also they have a stronger strength that I will try next time I get sick, but that is more expensive.

I am fully cured of my sinuses no problems! :) Clear healthy sinuses , yes expensive but totally worth it!!

Other information: they are good quality as they did not hurt my stomach, as I have a sensitive one. Highly rated on Amazon, have also tried now foods, those hurt my stomach but are ok. Will be buying some to have for when I get a future flu/infection.

Oregano oil: anti fungal, viral, bacterial... etc

Earth Clinic rocks! Peace.

P.S. if it helps you can you please post a comment below. Thanks!

I have used oregano oil to effectively fight lots of things. A doctor turned me into it but WARNED, like antibiotics, it shouldn't be taken more than 10 days in a row. It's hard on the stomach & you can get an immunity to it if over consumed.

I strictly use the oregano oil. It can cure many more things and sinus, but it stopped the flu virus with 30 drops of oregano oil in it my water, gone the next day Yahoo!

My daughter uses all types of oils for her family and after having constant blisters inside my nose which seemed like they would never heal, researched and told me about oil of oregano. I use it on the bottom of my feet at bedtime and within a few day, the infection was gone. The first sign of another infection, I starting using the oil again and haven't had an issue since.

I am prone to sinus infections but I refuse to take antibiotics because they do not work. This morning I was sitting on my patio reading the post on apple cider vinegar and oil of Oregano and I though since I have an infection now and the mucs is green and presure around my eyes why not try the apple cider vinegar which I give to my husband for acid reflux and it has done miracles for him. I made some turmeric tea and honey and put two table spoon of apple cider vinegar and went to my garden where I have fresh oregano I put some in my tea as well, I also pressed the leaves till some oils came from it and put it in my nostril and under my tongue. Whithin 5 minutes I started feeling the presure subsiding and my nose opened up. I will continued with this and will keep you posted.

I found Oil of Oregano the most effective!

I had a sinal infection a while back. The prescribed antibiotic didn't work. After two days, I gave up and used the OOO instead. I took the kind that has 64 mg Carvacrol and Thynol, 3 capsules 3 times a day to start. Improvement was felt only two hours later, much less pressure the next day! 9 capsules a day until infection was under controlled (you can feel the action, definitely), followed by 2 by 3 for 3-4 more days (infection gone) and 2x2 for another week for maintanance. I was so convinced by this herb that I would take 2x2 whenever I feel anything funny; gum infection, viral infection in a cold, etc. The infection would usually go away within the same day. Of course, we are all different - the way that worked for me might not be the right thing for you. Pay attention to your body's reaction while taking it. I didn't have any side effect taking 9 capsules a day. I found it insufficient when I tried to get down a bit. I would, with no reservation, recommend this wonderful herb to anyone.

First, I love this site and especially Ted.. you are a gift to us all.

I have struggled with sinus infections most of my life, but never like I have since moving to Southeast Alaska where pollen and mold proliferates. Being a Type 2 Diabetic, I am prone to infections and don't always adhere to the sugar free diet as I should. Last year I spent more than 5 months with a chronic respiratory infection that was finally arrested with my 3rd round of antibiotics and supplemented with Oil of Oregano drops.

I have been infection free until about a month ago. It flared up again and has caused me severe pain, fever and chills until I saw the dr last week and was placed on another round of doxycycline (I am allergic to most antibiotics.. This is one I can still take). Well, after a week, it should be gone, but it isn't. In fact, the fever and chills are returning. Today I returned to your website to review the options again (I used the neti pot but it's not working on this one). I read about the oil of oregano and went in to get my bottle out of my first aid kit. Rather than use drops under the tongue, I went straight for a Qtip saturated with the oil and swabbed both sides of my nasal cavities as far up as I could comfortably get the Qtip. Within seconds my nose began to burn from the oil, but relief was almost immediate. I sat down with a cup of hot tea and suddenly felt the stuff break loose in my cavities and start down my throat. The heat of the oil set me on fire, literally. My eyes teared up and I felt like I had sniffed a handful of horseradish up my nose.

I have absolutely NO SINUS PAIN. It's as if I imagined the problem. I plan to take this direct approach (and hope there are no side effects from oregano oil directly applied to the sinus area). The result is amazing.

Oil of Oregano should never be used directly on mucous membranes. Do not do this.

You can simply put it on the skin outside your nostril.

I had been sick with sinus infections and lower respiratory problems for 2 and a half months - I went through 2 rounds of antibiotics that failed - I finally put a few drops of oregano oil in a pan of water I had just boiled and threw a towel over my head. I breathed in the steam (with my eyes closed!) for about 10 minutes. The next day,I can't say I felt better, but "different". Every day after that I felt better and better, and after the 4th day I was no longer sick - at all. I mentioned this to a friend of mine who was sick and she got the same results I did - I will do this everytime I feel like I may be getting as cold or flu - it was amazing for me - and free, since I already had the oil in my medicine cabinet!

I recently was having a terrible time with post-nasal drip, which, when I woke up in the morning, started feeling as if infection was setting in. Not a fan of antibiotics, I tried oil of oregano as I've used it to treat colds in the past. It really does taste quite awful which is why you have to administer it in drops under the tongue. But I felt immediate results and am now on my second day with it. I no longer feel as if an infection is setting in and there's a noticeable difference in the amount of goop in my throat - and my voice even sounds better. Highly recommended!

Miracle, wonderful remedy. I tried this last night and I slept like a baby. You are right it was as if I had never had a sinus problem. I gathered some fresh oregano from my neighbor's garden and heated it in some olive oil. I put the oil on a q-tip and swabbed my nostril membranes. Then I held the leaves under my tongue, until dry. I feel wonderful! God is good and his herbs are fabulous! Thank you!

For those looking to use Oil of Oregano for it's antimicrobial properties, I would like to specify that Oil of Oregano is NOT Oregano Essential oil, which would have to be diluted. If you're looking to buy this remedy, make sure that the ingredients list states that there is a carrier oil (like olive oil). Otherwise, be prepared to dilute it yourself, or there could be serious negative effects.

I have seen some people writing in remedies that include putting undiluted essential oils on their skin. I think I saw a remedy for headaches or migraines that recommended putting peppermint essential oil on the temples. I have been studying aromatherapy for 5 years, and one of the most basic lessons is that you almost NEVER use essential oils undiluted. Peppermint essential oil in particular is considered to be a skin irritant to all skin types when used undiluted. If put on the temples, the strength of the fumes could seriously irritate the eyes and the delicate area around the eye. If you are going to try any remedy including essential oils, DILUTE FIRST! Even if the remedy doesn't specify it, you'll be saving yourself from possible complications.
