The Health Benefits of Oregano Oil

Oregano oil is an essential oil that has both antibacterial and antioxidant properties in laboratory studies, but benefits for people still need to be studied.

Studies in human cells and in animals show that oils from the oregano plant have definite antibacterial and antioxidant properties. These oils can break down the walls of bacterial cells and may help fight infections. As an antioxidant, oregano oil may scavenge free radicals and prevent damage to healthy cells. [1] Some studies also suggest this oil may help fight viral and fungal infections. [2]

The oregano plant has been used as a spice for thousands of years, and the best oils come from Greece, Turkey, and Israel. The active antimicrobial and antioxidant ingredients are the organic compounds carvacrol and thymol. The amount of active ingredients change between types of oregano and where and when the oregano was harvested. [1]

Why do people take oregano oil?

According to the National Institutes of Health (NIH), oregano oil is taken orally to treat upper respiratory and lung disorders like cough, asthma, or bronchitis. It can also be taken to relieve indigestion, menstrual cramps, urinary tract infection, headaches, and pain from various conditions. [3]

Oregano oils can be rubbed on the skin to treat a wide variety of skin conditions including acne, rashes, infections, psoriasis, joint pain, and as an insect repellant. [3] As an essential oil, oregano can be inhaled as a vapor to treat sinus and chest congestion. Some of the stronger evidence from animal studies is for oral use to treat inflammatory bowel disease, candida yeast infections, and a variety of bacterial infections. [2]

What does the research say about the benefits of oregano oil for humans?

Although many people use oil of oregano for many reasons, benefits in people have not been shown. However, that does not mean they do not exist; it simply means there are not enough human studies to prove the benefits. According to the Natural Medicines Comprehensive Database, which rates effectiveness based on scientific research, oil of oregano gets a rating of insufficient evidence. [2,3]

How much oregano oil is safe to take?

According to NIH, oil of oregano as a spice is safe when taken orally in the amount normally found in food. When used as a medicinal oil supplement, it is only rated as possibly safe, because there are not enough human studies to establish a safe dose. [2,3] The best advice is to take oil of oregano by mouth only after checking with your healthcare provider. [2]

When used on your skin, oil of oregano is considered safe if the concentration is one percent or less. [3] Stronger concentrations may cause skin irritation. [2]

What are the possible side effects of taking oregano oil?

The most common side effects from oral use is an upset stomach. Oil of oregano is not considered safe during pregnancy or while breast feeding. Allergic reactions are possible, especially if you are allergic to other plants in the same family, including basil, lavender, mint, sage, or rosemary. If you have diabetes, you should check with your doctor before using oregano oil. It may interfere with some diabetes medications, and it may raise blood sugar. If you are going to have surgery or you are taking a blood thinner, check with your doctor because oil of oregano may increase bleeding tendency. [2,3]

When shopping to buy oil of oregano, keep in mind that essential oils are not regulated for dose or safety by the FDA like medicines are. Check the label to look for the Latin name Origanum vulgare, and don’t use the oil if there are other ingredients listed. When in doubt, check with the pharmacist. [2]

The bottom line on oregano oil is that it has lots of potential benefits. Unfortunately, none of these benefits have enough research to recommend use in humans. If you want to try oil of oregano, talk to your doctor first. Don’t use oregano oil on your own in place of proven treatment for the symptoms you’re trying to address. [2,3]

    Can you help me

  • I’m not really big on taking supplements, preferring to get all my macro-nutrients, vitamins and minerals simply by eating a very healthy diet. But as a special case, every morning I take a single Oregano Oil cap (one that contains 32 mg of carvacrol per cap) because of its reputation for providing so many additional health benefits.

    My bother and I, both retired, live together, and this winter he came down with a really bad case of the flu, norovirus I suspect. He suffered with it for a couple of weeks, just couldn’t kick it, and I figured I would certainly catch it from him; but amazingly I never did. Doing some online research I stumbled across a reference to using oregano oil as a treatment for norovirus. Figuring it was at least in part the oregano oil that kept me from catching the flu from my bother, I suggested he give it a try. After taking three capsules per day for three days he finally got better, and now he too is continuing to routinely take one cap a day.

    Of course this hardly qualifies as proof that it was actually the oregano oil that made the difference in either of our cases, but it certainly reinforced my decision to continue taking it as part of my daily routine.

  • I’ve had good success with oregano oil, but I can’t tolerate the taste of the liquid. Greg, what brand of caps do you like? I’d like to try that instead.

  • I recently infused some oregano into olive oil. Didn’t plan on using it so soon but about the time it was ready for use, I came down with a UTI. I used 1/4 teaspoon x 4 daily for 10 days (number of days based on most antibiotic dosages. I am free of the UTI and now restarting the probiotics into my system since I am aware that antibiotic kill pretty much all bacteria good and bad. BTW…I like this better since I can put my dosage into my meals which makes it easier to take.

  • I got bite by a cat. On my ear through the cartlage. 6 months ago. Ive taken 4 antibiotics. Used one antibiotic cream. Seen three docs and an infectious disease doc. My body is so blown out from the meds that i just cant take any more. Ive been on oregano now for 5 days. My ear and face feel better than they have since the bite. It os finally going away on the inside. The ear is still bad. Skin wise. Tried many things. Even EO of oregano. Finally i found a mineral cream Earthseaskinplus and an EO called Owie for kids. I put this on the ear in very small amounts. The cream first then just the tinyest bit of owie oil. Not even a drop. Just a touch to a glass dropper. The skin on the ear must also breath. This is amazing how much it is helping. I can only wait and see if it heals completely. And then doesnt come back.

  • I’ve succesfully burnt out my genital wart,from my pubic region in about 3-4 days.but it burnt like hell,it gave me quite a nasty scar,but eventually it healed.they didn’t came back since then(it’s been a year aprox.).i dont reccomend to put it on genitals! I’m quite shure that if you take small oral dosages too,it’s even more effective and it kills the problem from it’s “roots”.It gave me a huge releef…it made me happy again,it put me back to normal

  • I almost died four years ago from a staph infection in my arm (celluitis) due to my having had one lymph node removed ten years previously for breast cancer diagnosis. I was hospitalized for five days and had reactions to many antibiotics, both oral and systemic (intravenous). I now can only take one antibiotic for my celluitis on an outpatient basis , which has a severe side effect of causing almost total insomnia. As we were going on vacation last month, I got a spot of celluitis on my elbow. Not wanting to ruin our vacation with insomnia, I turned to Dr. Google and realized I could take does of oregano oil, which kills staph. I took three tablets of 70% carvacol oregano oil four times daily for a week. The oregano oil knocked out the infection one day faster than my antibiotics had done. I coupled this treatment with my lymphedema massage and wearing a compression arm and hand sleeve, as instructed by my lymphedema specialists. This success has made me so much more reassured and self-reliant. I did some research, as my oil of oregano was over two years old. It seems that it stays fresh indefinitely in the capsule. So no more worrying that my antibiotics are out of date. I did use probiotics for one week subsequent to my treatment to restore my gastrointestinal flora. Surprisingly, the oil of oregano also helped my other digestive issues and my asthma. My allergy cough subsided and has not returned. My naturopath is delighted; he believes asthma is a reaction to long-term, low level infection in the lungs. I hope my comment helps someone else who has developed resistance to many if not most outpatient antibiotics.

  • Taking 300 mg a day maintenance am for repeated Uti symptoms for last 4 wks. Evening taking 60 billion probiotic. Seems to be working. I have suffered over 5 yrs with repeated Uti symptoms, many times no positive test results. Also cut sugar and yeast from products and breads. So far so good. I have tried so many other herbs and product, lost count. In my opinion, Doctors don’t follow through with proper referral or testing, just antibiotics which complicate my issue.

  • Hello, I have Giardia from Nepal/India since four months. Took 3x Antibiotics but the Little creature did not disappear. Now before the doctor advises the next big medicine, I would like to try Oregano oil since I have heard great things about it.

    Also I would like to know how to take it, if I have a parasite like giardia and is there someone here who has tried this? Thanks for your help 🙂 Miri

  • I don’t recommend diluting with “water” if you are taking it orally, and if you are mixing “pure” oregano oil. Oregano oil that is 100% pure is very strong, and it will burn your skin, and your esophagous if you swallow it undiluted…and of course, oil and water DON’T mix. I accidentally tried it that was the first time, and the oil stayed in my throat and burned it. Dilute iwth Olive oil first if you plan on swallowing it, or you will regret it. And if you are using it topically, if you rub a large area of pure oregano oil, it will burn enough to make your skin peel. (although you can use a Q-tip, and put it cautiously…on pimples, or whatever, but don’t use big globs of it, be conservative!)

  • to take my OOO I drop 4 drops into a gel cap and just take it like a pill with water to swallow. makes it easy. I have imflamation and hurt most of the time. this has helped take the edge off, and I have more energy

  • I have the potent good quality oil of oregano and there’s no way i can take this as it burns, i want to take for an UTI, my son days you use about 3 drops and mix with milk them drink milk straight afterwards to counteract the burning. I really would like an answer to this one if poss please as ill do anything to get rid of this painful UTI

  • I see a lot of people leaving info on here but not really giving a full description of what exactly you are taking. I found some capsules that are 75%-80% Carvacrol and each capsule is 50mgs. How much should one be taking for a maintenance? 500mg seems like a ton of pills. Any help?

  • Hi! How many times a day do you take this? Also for how long? I have Candida and Oregano Oil is an excellent way to kill it.


  • Last winter after two rounds of prescription antibiotics for a UTI and no end to my symptoms, I looked into essential oils. I have bunches for soap making and figured I had something effective on hand. I found advice online recommending 5-7 drops taken internally 3-4 times a day. I went with 4 times a day, taking it with water, immediately followed by milk and some bread to counteract the burn. It’s one of the nastiest tasting things ever. It burns which is why if you can get capsules, you’ll get it down way easier. I took it this way for seven days. I felt better by the second day, but wanted to be sure it was gone, thus the seven days.

    I now have another UTI hanging on after one round of ineffective treatment with a prescription. This is day 2 with oregano oil and I’m feeling much better this evening.

    I’ve tried diluting with both water and olive oil. I found that the olive oil coats my mouth and throat, prolonging the burning. The water, though it doesn’t mix with the oregano, carries it more effectively. I use about an ounce of water, followed by fill glass, followed by milk and bread.

    As it’s both antibacterial and antifungal, it’s taking care of the yeast infection that the prescription antibiotics caused. If you’re unsure if you have a UTI, you can order the urine test strips doctors use online. If you’re worried about the sterility of your cups or want disposable, sterile urine sample cups are also available online.

  • I had dental surgery but refused the antibiotics from the dentist. A few days later I had some pain at the point of surgery which gravitated to my ear on the same side. I believed it to be infection setting in. That night I took half a cotton ball and soaked up half a teaspoon of coconut oil into it and added one drop of wild oregano oil. I put this between my gum and cheek and slept with it in my mouth over night. The pain was gone in the morning. I did it a second night for good measure and took a couple drops of oregano oil internally twice a day for two days. Worked like a charm.

  • I too doxycycline per dr I one time a day on 6th day had a rash and hot burning in my era took children’s dye free benadryll was sick 3 wks prior to taking got better but now can’t not sure if I have bacterial dr thought I will do oreginal p73 again what dose any suggestions?

  • A friend had a sinus infection so bad that sneezes smelled bad. He read about oregano oil and tried it. After a couple of days he began sneezing a lot and blowing his nose – having lots of mucous. His sneezes stopped smelling bad and he said he finally was able to sleep well because he could breathe better. He was amazed so I went out and bought a bottle. I have told everyone his story. I take it every day as a preventative measure.

  • I put 4 drops of oregano oil in 1/2 cup of boiled water and 1-2 teaspoons of honey, stir well. Drink it while it’s hot. I do this 4 times a day when I have a cold and it clears it up quickly.

  • I have some type of parasite worm(s), I started using Wild Turkey Oregano Oil under my tongue, 1 drop 3 x a day. I had a heart attack and stint in 2014 and I guess with that, the oil raised my blood press almost to 200/115 so I stopped. I feel confident that Oregano will help expel these worms in my stools and also from ny nose. Cn anyone advise me how much less to use to get some good effects? I’m one of the billion people that the docs refuse or don’t know a thing about parasites and how to kill them. I’ve been turned down by Infectious Disease Dr. and my PC’s take a hike, want no part of it. Too bad for a 89 yr old senior wom,an

  • I got a cold sore ( that I rarely get) and put a drop on it as soon as I got in my car after buying it. Put a second drop on 4 hours later when I went to bed. It was 90% gone next morning, and one more drop that day got rid of it.

  • I have been using oil of oregano for years. At the first sign of anything, I start taking it 3 times a day. If I get it at all, it will only last a day, three days tops. I came down with shingles once and your dad and less than 2 weeks but taking it 3 times today or early and applying the oil to the ranch itself. Wild oregano is some really powerful stuff and no medicine cabinet should be without

  • I could not see my comment while I typed it because of everything that was in the way of the comment text field. The previous comment did not come out as intended.

  • Last year I was so sick that I took antibiotics so many times that I became allergic to penicillin! My daughter recommended that I take oil of oregano. I started taking oil of oregano for a sinus infection 75 to 85% carvacol. I was taking 5 drops 3x daily under my tongue for about a month, To my absolute delight it not only cleared the sinus infection but also my psoriasis! I would love to take this daily, but am worried about damage to liver or kidneys? Anyone know anything about this? Thanks

  • It is a wonder drug and should e investigated in the treatment of cancer. I had a suspicious growth on my breast and I used oil of oregano topically and orally and it was gone in 1 week.

  • I was getting sever ear infections from my hearing aid molds. After spending hundreds of dollars at the Dr’s and for meds, my daughter recommended oil of oregano. I diluted 2 drops with baby oil dipped a cotton ball in it and put it just in the opening of my ear, not only did it take away the pain but pulled the infection put of my ear. I now use it when ever I feel an ear infection starting as well as for other healthproblems

  • Hi. Are people getting responses from all these great questions? It would be great to see some of the answers. I take a small dose of BP medicine and also seem to be reacting to high histamine foods. I will get stuffed up right away. I know that mint is something I react to. I just bought Oregano oil and will try it with my manuka honey. Manuka Honey is wonderful. I get chronic sinus infections. I started getting reactions from Sulfa, levequin, cyclor so there are not many left for me to take. I recently was cultured and had Psudeomonis. Where the hell I got this, I don’t know. So now I am looking for a natural way to deal with it. Any help is appreciated. I just found out about this site. Is there a forum? Thanks.

  • Wanted to share my cold cure. I’ve found that if I take Oil of Oregano at the first sign of a sore throat, I can kick it in one day. The key is to bathe the throat in the oil repeatedly. I buy the capsules, and bite down on the capsule to get the oil out, swallow the whole thing. It burns a bit, but just think of the bad bacteria getting burned out of your throat. Wait a few minutes (or as long as you can) before chasing with water. I do this 4 times; sometimes I feel better right away, but every time I’ve done this I’m better by next morning, no sign of sore throat, no sign of a cold. I’ve never tried anything but capsules because that’s what they sell at the grocery store around here.

  • I take the oil of oregano in the winter for maintenance. But I have gotten a bad cold. Sometimes it even fells like the flu but i have been sneezing almost all the time. I am on day three of this bug. I have been reading the comments to see what I should do differently. I am now at 7 drops three times a day. I am putting it in raspberry lemonade. I don’t taste it one bit. Maybe i should do it in water and chase it with the lemonade. When my husband got sick last year, I did the exact same thing for him and he was better in two and a half days and the person that got him sick was still sick for another week after that. I do all natural stuff and this is the first i have been sick in three years. I did make my own batch of oregano oil. I used organic coconut oil with the oregano from my garden. I just have to strain it still. I am going to order some empty capsules to put them in there. To make your own, just get some oregano and put it in a mason jar. Cover it with olive or coconut oil. Put the lid on and put it in a almost boiling water bath. I left it sit in the water bath for about 30 min. then I’d shake it every so often. the coconut oil is now green looking. I used coconut oil instead of olive mainly bc I hope the taste would be a little more bearable and coconut oil is equally better if not more than olive. I don’t feel like straining it yet but i need to. I have it in the fridge for now. Keep the comments coming so we can learn from each other. Thanks and good luck!!!

  • Just a question regarding another possible use – I have copd plus use a cpap that has a hydrator at night. Is there a way the oregano oil could be fed into the hydration system for breathing the oil.

  • Oregano Oil capsules have been my savior in my fight against recurrent pilonidal abscesses. I take them when I feel a flare-up coming on, and they get rid of the infection without side effects. I hate the thought of what prescribed antibiotics do to my gut, so this has really been a miracle to find a natural solution. I swear by it and sing its praises any change I am given to do so.

  • I use wild oregano oil. I had forgotten about it in my cabinet. I got bronchitis in October. My doc wanted me on antibiotic but I can’t handle them. I remembered my oil of oregano and took 3 drops under my tongue 3-4 times a day for a week. It worked and I felt better within the first 2 days. BUT everyone must remember, it kills the good bacteria in your gut too, so just like an antibiotic, when you are done with your round, then you must take a good probiotic for awhile.

  • Taking Oregano Oil Sanely- The best way to take it is to use only 8 drops in 3 or more tablespoons of virgin organic coconut oil. Put this in a small bowel, then mix it. Next take 1 1/2 cups of Brown cooked rice and add it into the oil. Mix well and eat, then lick the bowl to get all the oil. If you do this thing for 2 or 3 days you well probably be cured. 8 drops once a day is plenty in this method. Remember no matter how much you dilute you are still going to ingest the same amount of oregano in your body. So the important thing is don’t under dilute for internal use. Over dilute means nothing, unless you are using it externally on the bottoms of the feet.
    WARNING: Oil and water don’t mix and no matter what you are drinking, during or after- you are still ruining your digestive tract and it will be eventually damaged beyond your belief!!! Don’t do it!!! Some people will have it happen sooner and some later, just a matter of time.
    As far as capsule goes, you have the same problem in the stomach similar to the aspirin and the digestive tract problem. Don’t do it.
    Think about it- the oil is going into your body and being carried throughout either externally or internally, so you cannot target just your intestines or one area of your body. Sure if you want a little more concentration then put the oil externally on the lower body, but it is still carried by your body fluids. There is a lot of misconceptions out there by the general public and even some doctors as this field is very, very new to all. And everyone is experimenting. Also remember over use can render it ineffective or even cause allergies- this oil is a medicine and to be used similar to a bandage (only when you need it). And not everyday!!! Look before you leap…

  • I used Sprouts oregano capsules for a tooth and gum infection and it helped alot, I had no dental insurance and needed antibiotic, I dont recommend waiting to see a doctor in this case because a gum infection can spread to the rest of your body if left untreated .. so u need antibiotics, pharmaceutical or natural, but the infection must be stopped..I used baking soda and vinegar on a q tip to keep the gum cleaned, I also applied gum was very painful, but the oregano soothed the pain it was such a relief..the oregano capsules from sprouts store have already been mixed with olive oil and lecithin which is a plus for gums because when u pop open the capsules the oil is thick so it sticks better and u just massage it in and around the tooth and gum area, I will caution it still can burn, so if u are really sensitive u can dilute further with olive oil, but the sting goes away in a few minutes and u will sense a relief in pain, I also took the capsules internally as well, it was totaly healed in about 5 to 7 days I cant remember exactly…since that time I keep a bottle handy for other uses..its good for pain in the knee, pop open capsules and massage into the knee, ear infection massage around the outer ear for pain, many more uses, just remember the oregano I purchased was already diluted and the reason I mention this brand is because I tried others and they did not work on me, so u might have to try different brands in your area to get results, I hope this helps someone because I was desperate at the time and in alot of pain I asked the LORD for help and he answered through a small oregano capsule 🙂

  • I have another UTI bt started Oregano oil at my own risk. Got antibiotics as weekend was near, incase I needed them. However, Can I take O.Oil also with other drugs from GP. Also can I have wine evening time, while consuming O.of Oregano. Also my son got over his Pneumonia with O.of Oregano.

  • It is wise to keep oregano oil capsules on hand at home and while traveling as it will stop throat or chest infections quickly by taking two capsules every four hours for two or three days. This is also true of painful toothache infections.

  • Sorry for putting my question here .
    I have 100% pure essential oregano oil by Aura Cacia , with a caution warning to avoid mucous membranes.
    Does it means not to inhale steam with its drops diluted for cough and phlegm ?
    Should for above reason , food grade oregano oil is the right selection .
    Please help

  • I added Oregano oil 2 drops a day, to Agracept 4 drops to treat the symptoms of Lyme Disease that was misdiagnosed and left untreated for 11 years. It is helping tremendously … adding the Oregano relieved so many of the symptoms like joint pain, brain fog, fatigue. I highly recommend it.


  • I was diagnosed with Ankylosing Spondylitis in 2008 a couple years after having getting some type of
    pneumonia-like infection which lasted 4-5 weeks. I progressively became more and more reactive to a variety of foods which cause peripheral and spinal pain and eye-irritation/inflammation which
    last 2-3 days if I immediately return to a very strict diet. A few years ago I learned about taking
    Oil of Oregano capsules to try to cut both the length and intensity of these debilitating pain episodes. I am so grateful to have learned this as it really works and helps a lot to reduce the pain and inflammation to more tolerable levels and reduce the length of the episodes from 2-3 days down to 1 day or less. I don’t know much about dosage, but just take 3 capsules per day for a few days. I see each capsule is only 50 mg with 75-80% carvacrol. I have tried numerous over-the-counter and presription medicine for this type of inflammatory pain caused by reactions to foods, (especially starches) and additives (like maltodextrin, now guar gum too). NOTHING has helped in any way other than strict adherence to an increasingly strict diet AND Oil of Oregano when I accidentally “slip-up” with my diet. I am so happy to learn all the other condition for which Oil of Oregano can be helpful. Thank You All !

  • It is a natural antibiotic. I take 4 drops 4 times a day for UTI or basically anything that calls for antibiotics. I take for 1 week and always have success. It is amazing.

  • My mom, 75 years old.she has been coughing on and off for almost 3 years.she was seen by Dr and was treated with antibiotic on and off. At night she hardly sleep due to bad cough,
    and produce lots of sputum. 4 months ago i was introduced by a friend on the benefit of oregano oil. I bought a bottle and let my mom try.I add 2-3 drop of oregano oil in an empty capsule and add virgin coconut oil.For the first week she took it 3 times a day.then reduce to twice a day and gradually daily. Amazingly her cough get well.She stop taking it.But recently she start to have flu.I told her to take once a day. Would it cause any harm if she take it daily for a long period.Please advised.Thank you.

  • Oregano oil is my “go to”….first sign of something off and I begin taking it. I do not take prescription western medicines–I have found that most have superior herbal or homeopathic alternatives that work with out the awful side effects. Natural remedies sometimes take longer but I feel it is worth it. I buy the strongest oregano oil that I can find and carry it with me when I travel–especially to third world countries. I use dropper to fill empty vegetarian capsules right before needed. After reading comments above I am now going to try it externally…even though I do not like the smell–it will be worth the smell if it works. Traditionally, oil pulling is best with plain raw organic sesame or coconut oil (both have antibacterial qualities) but I like the idea of adding a drop of oregano oil for an extra kick also as suggested above. I am grateful that our planet blesses us with many healing treasures!

  • For genital herpes outbreaks: I take 4 drops sublingually daily for prevention, also with 4 drops of olive leaf extract. I use the 25% purity oil of oregano, which is premixed with olive oil and is sold in most health food stores. I take it on an empty stomach and try to wait one minute before drinking water. If I feel an outbreak coming on, I take this combination three times daily. It has worked for me. I used to get outbreaks every 5-6 weeks, but now I get them 2-3 times per year. I still have to take Acyclovir for the outbreaks, but not as much and not as long as previously. I am male, early 60’s, good health, good diet.

  • Oil of Oregano is amazing, I have used in place of antibiotic more than once over the years, but, please everyone, note what someone posted in December 2016. Seems they are the only one to mention it and it is very important. You must take a probiotic after your round of OOO. It does also kill good bacterial in your gut. The person I purchased mine from told me I will need a probiotic. All people who sell OOO should be telling the buyer to take a probiotic!

  • Someone told me that oil of oregano should not be taken (daily) for more than 2 to 3 weeks as the body gets used to it or its potency gets less and less. Is this true? if so, how many weeks are advised?

  • Not sure if this gets absorbed as much as sublingual(because sublingual veins go through bloodstream) but even diluted I couldn’t stand the taste. I just got a pill-sized piece of bread, put 4 drops on it , folded it once then swallowed it and drank water after! Best thing EVER!!! Can’t taste it!

  • I’ve hard green sinus for two years left side plugged
    Took for10 days energy ,my fibro I have no pain.
    Wow glad I got sick I feel better.
    I hope or wish others could experience this

  • I was fighting an infection after a mole removal on my upper leg. Turns out fungal infections use melanin as armour and that’s why they can grow back; the cause is still there.
    My little infection site.became swollen, red and inflamed one night, but rather than using my usual go-to of a healing castor oil.pack, I see what my organic oil of wild oregano on the swelling, which was about 1/4″ high past skin level. Not 20 mins later and the swelling was gone! I was mightily impressed. That infection has since healed nicely after this miraculous oil finished off the cause. Fungus “hates” oil of wild oregano because it dies.instantly! I am now taking orally 5 days out.of 7 when I’m fighting something and 3 out of 7 for maintenance, 350 mg those days. It works very well for me so far. I luv.this stuff!

  • Everyone reacts differently to each medication, as does each person respond differently to each essential oil. Precisely why a good reference guide for EO’s will give several options for ailments. It’s not a “one treatment serves all” kind of thing. Get a good reference book, or a friend who has one. Do your research. I use Oregano EO for infections, always successful. But not so much for other family members. Always use caution with amounts and duration. Be sure you know where your oil comes from. I’d NEVER use Wal-Mart oils internally, nor diffused. Not sure who bottles theirs.

  • I have successfully treated several major tooth infections with oregano oil. In the past, I would have ended up in urgent care due to the severity, but now I start with oregano oil and it is cleared up within 2-3 days.

  • Can’t speak enough what this has helped me with. I use to have systemic candida and when I got sick with continued respiratory infections I was in great pain. I use to live on antibiotics for years and when I got sick with bronchias my asthma would flare up terribly. I’d run and get another antibiotic from pulmonary doctor and of course this was a visions cycle making it worse. Folks, candida is most times the problems to our triggers of respiratory and sinus problems and to find out I can just take oregano oil to combat these problems is a blessing/miracle. The last few days I had the flu. Since I was always sensitive in my lungs it immediately attacks them. Oregano Oil to rescue. Yesterday was a terrible day, aweful weakness, croupy cough, painful throat, like swallowing golfball, headachy, neck pain. Anyway I started the oregano oil as soon as I felt it coming on 4 days ago so continued use with oil I felt the relief slowly, I’d also use HP in nebulizer and amazingly enough today I am doing great!! As long as I get that mucus out as I go along it soon all eventually goes away naturally. I will always have to be aware and on top of my symptoms, but my life is 100 percent better. I also build my immune system with nutritional shakes. I believe in natural ways today, so grateful I found the benefits to oregano oil. By the way capsules work best for me.

  • I am suppose to take a large dose of antibiotics before dental work. I heard about oregano and wanted to know how much of the essential oil to take prior to dental work. I use Doterra oils.

  • I have a history of UTIs. I also use Essential oils – but had never heard about Oregeno oil and it’s health advantages until about 6 months ago. Shortly after that I incurred another UTI. So, instead of running to the doctor or clinic and being given antibiotic – again! I started to put 3 – 5 drops of oregano essential oil in a veggie capsule. I did that 3-4 times a day for 5 days, then cut back for a couple more days (less times, less drops). Drinking lots of water too. I did not need to pay out money for a doctor or for antibiotics. I was SO happy!! After 50 years I have finally broken the constant trips to doctor. (I also started a probiotic for urinary tract). Halleluia!

  • I cut my upper lip and skin. I was watching it carefully, but it did develop an infection. I went to walk in clinic- they wanted to “shoot me up” with powerful antibiotics. I declined, as I have been on special immune boosting vitamins & probiotics and I didn’t’t want to kill them. So.. I tried the oral oil of oregano (Oreganol P73, as it was pure and had clinical studies backing it up). I am disabled – I had a very large ventral mesh implanted after a huge hernia; post hysterectomy & I have problems from that (lots of adhesions).
    Well- I after taking the OOO capsules, I thought my guts were burning from inside out! I tried another dose the next day- same thing: terrible anxiety, severe GI pain Does anyone have thoughts on what may have caused that reaction? I’m not allergic as I can other herbs in same family. I actually wondered if the OOO was eating up the adhesions…? I would love ideas on that. And BYW: I did cut open the pearly capsule of oil and dribbled on the wound. It burned a bit but it started clearing up right away! And I started feeling better. Can anyone comment on this? Or has anyone had a similar experience? Thank you very much.

  • I have been dealing with allergic ryanitis for about 3 years. They can’t identify what I’m allergic too. It results in sinus infections and bronchitis as well as pneumonia. I end up on antibiotics and steroids for a year straight and gained 50 lbs. I want to try this natural remedy if someone can please advise me on what to buy and the best way to take it. I’m tired of hospitals and poisoning my body with all these medications. Desperate for an answer and a solution.

  • I work at a hospital directly caring for sick patients. As soon as I feel a cold coming on or feel poorly in any way, I take Oregano oil. Honestly, I cant stand the taste but it works so fast that I suffer through it. I’ve started adding it to a small amount of V8 juice, downing and then chasing with the rest of the V8 juice. Best way I’ve found to get it down.

  • I have been using Oregano oil (diluted with olive oil) topically to relieve Ringworm, but new spots are still appearing. I started taking it orally, a few drops sublingually at night. So far no change in symptoms after 5 days, other than making me super tired. How much should I be taking and how?

  • I got food poisoning in Taiwan. I started taking oregano oil. 5 drops per day 5 times per day. In about a week the infection was gone. I thought I was going to die and a friend of mine has been on antibiotics for over 3 years. Oregano oil made my urine akin to battery acid. I also used cranberry juice to flush out those hiding and propolis so they could not reproduce or form cysts to hid until later. I thought I would die but it worked.

  • Oh yeah, the was 2-3 days of fever so I had to throw another quilt on the bed and a couple days just stayed in bed. That is all I can remember except at first it totally paralyzed me for about 30 minutes and I continued to defecate and urinate over and over in the shower unable to control anything. I couldn’t even reach up to turn off the water so I just sat there unable to move.

  • It’s been a Long time since I’ve had to do wild oregano shots. When ever there is anything going on in my stomach. I do it, or I’m trying to convince someone else to do it. Just yesterday my wife got sick, and I’ll be picking some up tomorrow morning. The way we do it, is. First coat your mouth ? with milk. Then with about a teaspoon in a shot glass and through it down the back of your throat. (Just the oil not the glass.) Followed immediately by more milk. (Whole Milk not that 2% cr@¿p.) For UTI’s: 3 to 4 large cloves of garlic, preferable raw. Couple times a day. Had a good friend that used to get them couple times a year. Doctor everytime two weeks antibiotic most of the time it didn’t work. Now she doesn’t even get them anymore. Because as soon as she senses anything, right away w.e.oil. shots and garlic and it’s gone by the next day. Over 10 years now…. They say add a 1000 mg buffered vitamin c to your body twice a day and you can fend off small pocks…

  • Oil of oregano WORKS but I’m a little scared of it. I use it in place of an antibiotic and i probably take too much. 2 capsules of oil of oregano at a time with extra oil and food… But think about it. As STRONG as just a few drops feel–Many, many drops in a capsule and being released into your intestinal track (I don’t believe your stomach could transform it!?) Anyway… Here’s what I’ve noticed: It ALWAYS gets rid of a UTI–In combination with external antibiotic ointment (yes, I know it’s not a place people normally think to use it. But I was getting CHRONIC Uti’s and it felt like I was dying from all the antibiotics. This combo totally works (as does prevention using the topical Antibiotic ointment before sex). BUT… I feel like my intestines shut down for a day or two after using for 3 or more days. And right now, I’m about to try oregano oil for the first time for a sinus infection, and wondering is it worth risking my intestines over… Maybe I’ll try just one capsule 3 times a day and if it doesn’t make a big difference in 3 days stop it. I really am worried it damages my intestines…

  • I forgot to say, it only takes a day or two (again, in combo with a topical anitbacterial ointment like neosporin) for me to get rid of a UTI with oregano oil–Taking 2 capsules 3 times a day (of oregano oil). Prewarning again that I think that’s too much and could be damaging my intestines.

  • hi, I just read the entire amount of messages above. there’s a lot of information but there’s really no exchange between members, no question is answered specifically, it’s a little disappointing. I’ve been researching about oregano oil as a way to may be get a head start in fighting an infection with MAC bacterium (Myco Avium Complex lung disease).The conventional treatment. involves over a year of 3 differents antibiotics as the “bug” is resistant to most. If anybody is familiar with this condition , thank you for sharing your experience.

  • I started using oregano oil to treat lyme disease. It will ne now third week first I was taking 10 drops per day but after two weeks I cut to 5 drops. I am taking it wit with cinnamon and clove essential oils. It is best if taken with olive oil.. does any one knows if it works and how long does it take to cure lyme with it?

  • I have been experimenting with oregano oil for many years. It’s nasty tasting stuff but it works. I’ve researched it extensively. I believe most ailments are caused by an abundance of bad bacteria in your system. From what I’ve read over the years, every major disease can be linked to bad gut health. Oregano kills bad bacteria. It’s like a bomb that goes off in your system that searches and destroys the bad guys and miraculously benefits the good guys. I’ve taken it when people I live with get sick and I don’t get sick. I’ve taken it after I’ve gotten sick and my colds never last longer than a couple days. I’ve used it to fight parasites in my body. I’ve used it to kill planters warts effectively. I’ve used it on toe nail fungus effectively. I believe with all my heart that nature gave us all the medicine we need. I hope I never have to take pharmaceuticals again. Oregano has amazed me over and over again. Miracle in a bottle. Love it. Can’t live without it. Grateful to have discovered it.

  • Viviane C., I’m researching the same thing. Haven’t found out much though. This article says that for infections, you need approximately 500 mg, four times per day, to achieve the antimicrobial benefits. The Oil of Oregano I’m taking says that 4 drops contain 24mg of carvacol. Surely one isn’t supposed to take 84 drops to get 500mg????

  • I’ve used Oregano Oil for years. I take it in combination with a good quality fish oil supplement for anti-inflammatory benefits. I would not recommend anyone do this without getting with their Dr first and I did, because in my case, all of my asthma and allergy medications seemed to be resulting over time in far worse asthma that what I started with. So gradually, keeping a tight grip on my emergency inhaler, I began the process of weaning off of the prescriptions while making sure to get enough anti inflammatory supplements each day. And it worked. I haven’t touched my inhaler in over 3 years but I keep I keep one handy on the advise of my dr just in case. I used Oregano Oil in place of Celebrex after knee surgery and it worked just as well to get the inflammation down. Love this stuff.

  • My mom had chronic UTI infections. I researched Oregano oil and got my mom on it. No more UTI’S! But I do have a question about the dosage. She does 2 drops per day everyday. Is that to much? It is 70% carvovol.

  • The dosage is actually 50 mg 4x per day for a total of about 200 mg per day. You can take as much as 600 mg per day depending on what you are treating, but your dosage of 500 mg 4x a day for a total of 2000 mg is much much too high and will cause other problems!

  • Vivianne C and Cleo B. I was treated for mycobacterium avium intracellar complex for two years treated with the only three antibiotics used for this nasty little bug (2014 – 2016). It was during this time I started looking into holistic and natural approaches to health. Not once did my pulmonologist suggest using a probiotic. Addressing my weight loss he suggested I eat more burgers and shakes and tried to put me on a steroid … thanks but no thanks. I changed over to all natural, organic foods (which I still follow today), and juicing since my body needed readily available nutrients. Right when I came off the meds my pulmonologist declared me cured and retired. I tried to find a new doc but the good ones in town weren’t taking new patients so I just let it go for a few years. Then I started having extreme asthma like symptoms triggered by smoke, pollen, perfume … you name it! I couldn’t take enough allergy meds to make a difference. So, I found another pulmonologist but all he wanted to do was run a ton of tests, more ex rays and just treat the symptoms. I didn’t want to treat symptoms with pharmaceutical drugs and add more side efforts. I wanted a cure. I still want a cure. It’s like my lungs are on high alert for outside invaders! Very interested point … I never cough when I’m sleeping. I just feel like there is a low grade infection going on somewhere. The docs misdiagnosed my MAC infection for two years and they don’t really seem interested in figuring out why my body is over reacting. At any rate, I certainly understand the journey you are on. It is sad that there is no exchange between the people on here and no one is answering questions. If you would be interested in sharing information my email is

  • For colds and flu’s, Oregano is wrong remedy.

    Use beta glucan. Active ingredient is 1,3d, I haven’t had colds or flu’s for 10 years. I take it if I think I may be coming down with cold or flu. Epicor is one of the weaker beta glucans and even it works.

  • Oregano is a hot oil. I am surprised you say to mix with water and put under your tongue. Water does not mix with oil and would make droplets spread burning the delicate skin under your tongue. Isn’t it better to use a homemade capsule filled with OO or apply under feet? This seems extreme with a hot oil. Afraid to try :(. I got a drop on my finger once and by habit licked it off and it burned! Lol let alone under.

  • I caught a cold and had a sore throat lastnight. It definitely has lessened the length of time I’ve been sick in the past. I know this from my experience before I ever took oregano oil. My cold would last all winter long before starting oregano oil. When I get a sore throat I put a few drops of oregano oil, at full strength directly on my sore throat (without diluting). I let it sit for about 30 seconds. It stings but then after 30 seconds you drink some water. You can already feel some relief after a few minutes. I have repeated this twice. Usually once in the morning and once before bed. Today I woke up without a sore throat. Before I knew about oregano oil I’d end up with a throat infection and needed antibiotics. Oregano oil has a terrible taste but it is so worth a try! When it comes to the benefits vs the taste, the benefits outweigh the taste. I take 3-4 drops, 4 times per day when I’m already sick. When I’m not sick but know I’ve been around someone who is, I start to take 4 drops per day. The brand I take is called Holista Organic Oregano Oil Extra Strength 4 drops equals 30mg.

  • Hi,
    i see many people being confused about the fact that it burns their throat even though they mix it with olive oil.
    It’d be easier if you go in a natural supermarket, they have premixed bottle of Orega-olive oil. I’ve tried this since i couldn’t see my doctor soon enough, and it helped for a UTI.
    But you have to be ready for a horrible taste. You can be sure you wont have bad breath after.

    I still recommend people to see a doctor if symptoms stay even a little bit.

    Here is an example

  • I started taking oregano oil for severe heartburn. I take a teaspoon of olive oil with 1 drop of oregano oil – and it magically disappears. I also had athletes foot from swimming every day. My big toe nails were both discoloured and were coming away from the skin. I apply coconut oil with a few drops of oregano oil to my feet every night and put cotton socks on. The nails are now healthy again. It’s amazing stuff.

  • Oregano oil should under no circumstances be taken in its pure form or with water. It must be diluted with a carrier oil. It can do permanent damage to your mucus membranes otherwise, including the small intestine. The best way in my experience is to mix a few drops with 1 tbsp of virgin coconut oil. I makes it very smooth to ingest. I just put a spoon of virgin coconut oil in my mouth and then drop 7 drops into my mouth after the coconut oil has melted a little, so the oregano oil mixes with the virgin coconut oil immediately.

    An alternative is to premix one tbsp of virgin coconut oil with a few drops of oregano oil, put it in the fridge and then take it out and let it melt in your mouth.

    Since virigin coconut oil has antimicrobial properties, mixing in the oregano oil could have synergistic effects. I don’t know but it may…

  • I have been using P73 full strength, two drops under my tongue once or sometimes twice daily. That’s it. I do it strictly as part of a healthy diet/lifestyle regimen. I have had NO burning, NO adverse effects. Since I have followed this practice, I have not needed to take my prescribed asthma medication. Typically, if I go a few days without taking Breo, I start wheezing. Since I started taking North American Herb and Spice Oreganol (about a month), my script I picked up is sitting in my house unopened. It was never my intent to cure my asthma, I simply have not needed my medicine for the first time in SEVERAL YEARS. No wheezing, no rescue inhaler. My child has gotten a bad head cold which we would usually share, me? NOTHING. So as for this burning people are talking about, I’ve noticed what I’d describe as a “spicy” taste, but no peeling or burning under my tongue.

  • I tried 4 drops of OOO in water – per directions on the bottle. DON’T DO THIS!! I had a severe asthma attack – totally couldn’t breathe. It was only for @ 5 to 10 seconds but really scared me.

  • Unfortunately Oregano Oil did not work for me. Having had three bouts of Cellulitis in my Leg and being refused a low dose prophylactic antibiotic by my GP to stave off the frequent recurrence I turned to other options, largely bleach baths, Hibiscrub antiseptic wash and a daily dose of Oregano Oil made up of two different brands, namely P73 and Zane Helios direct from Greece. I’m currently virtually bedridden getting over Cellulitis attack number 4, and it took a three week dose of Flucloxacillin and Clarithromycin to finally show some improvement, even though my leg is still covered in weeping blisters. Please use a bit of common sense as to what you treat with Oregano oil as there are some infections that you cannot afford to mess around with or delay seeking urgent medical treatment. Either way, Oregano oil did not do anything to stop the recurrent infection nor decrease the frequency between each attack so please keep an open mind as to what it may (or may not) cure. In the interim, if anybody who suffers from recurrent Cellulitis and has found a treatment which has prevented or delayed the frequency of infections then please share.

  • My husband’s wound care nurse used manuka honey topically, to help his diabetic ulcers heal. I’m not sure what kind she had, but they do make a medical grade. He was also on appropriate antibiotics.

  • Speaking as a skeptic:
    You state that the “dose” of oregano il is 500 mg then recommend 1-2 drops of a 50% solution. But a typical drop of liquid only weighs about 50 mg. Unless those are HUGE drops, you’re not even close.

  • For those of you with chronic UTI’s I suggest you research the benefits of ‘D-Mannose’ as well as a hefty Cranberry supplement of 25,000+mg and don’t forget to take a 500mg Vitamin C (combined with Rose Hips and bioflavonoids for absorption) throughout your day.

  • I just tried it in capsule =150mg. I read it’s a blood thinner & I had issues w bleeding from other in the past. How much is a safe dose?

  • At 57 I started having recurring sinus infections. I do use a netti pot but was still having issues. The first one which cause facial and tooth pain. I went to the dentist thinking i needed a root canal and he told me it was probably a sinus infection. Saw an ENT who gave me a 10 day antibiotic. It came back again and I eventually asked for another prescription only to have it come back again. Decided to consult the health food store and they recommended colloidal silver nasal spray which eventually did the trick. It came back again and this time the health food store person said their customers had reported much success with an oregano oil based nasal spray (I’m not one for mixing my own tinctures). It was Sinu Orega and by the second day I felt significant relief with all symptoms gone by the 4th day. I have allergies and this spray has been fabulous. I’m a fan and will look into using oregano oil for other inflammation and infection issues. Thanks!

  • What is the proper dosage of oregano oil to fight Pseudomonas aeruginosa in my lungs. I have tried every medication and the last resort was tobramycin inhaler and I had side effects. Thanks

  • To the person with the cellulitis. My husband had this in his leg and antibiotics were not working. We used Colloidal silver, it cleared it up. Silver kills 650 different pathogens. Google Steve Barwick he has micro particle machines for sale to make the silver.

  • Hi, I’d like to offer a suggestion to all who are wondering what dosage of oregano oil to take on any given day, for what particular disorder, and for the length of the treatment.
    You can do muscle testing / kinesiology. If you do not know how to self-test seek out someone who does know how. You can also learn how to do these self-tests and become proficient and attuned to your body’s requirements and this can be used for getting the answers you are seeking for oregano oil, anything from food, products of any sort or any decisions you need to make.
    Blessings and heightened guidance be with you sll💗

  • I have had amazing results using the capsules on the feet with socks and taking other capsules orally.
    Children hate pills especially oregano oil lol. So as soon as I think they have been exposed to an illness or are starting to fight something, I cut open a capsule and put it on the bottom of their feet and rub them together. I then put socks on them ( we even have socks reserved just for oregano Oil called “oregano oil socks” lol as they do get stained). I do this before bed and upon waking up. My husband and I take it orally with the capsules or I’ll double up and put it on my feet with socks, as well. I swear by it. Nothing else helps us with illness like this. I do also believe In it for inflammation etc. but my only experience where I have true consistent evidence is with General viruses. I hope this helps.
