11 Amazing Benefits of Oregano Essential Oil

The health benefits of oregano essential oil can be attributed to its properties as an antiviral, antibacterial, antifungal, antiparasitic, antioxidant, anti-inflammatory, digestive, emmenagogue, and an anti-allergenic substance.

About Oregano Essential Oil

Oregano is a plant native to higher altitudes and normally grows in the mountains, which is how it is named “Oregano”, meaning “delight of the mountains”.

The disinfectant and antibacterial properties of oregano essential oil were first recognized in ancient Greece where it was often used for treating bacterial infections on the skin or wounds. It was also used to protect food from bacteria. The essential oil of oregano is extracted through steam distillation of fresh oregano leaves, which bear the scientific name Origanum vulgare. Its chief components are carvacrol, thymol, cymene, caryophyllene, pinene, bisabolene, linalool, borneol, geranyl acetate, linalyl acetate, and terpinene.

It is used in many ways, like in aromatherapy, which has been the most popular use for decades. You can also apply it topically onto the skin or with a carrier oil like coconut oil for improving your skin quality. Finally, you can ingest it in very small quantities as a dietary supplement, usually diluted with honey or other non-dairy beverages.

Health Benefits of Oregano Essential Oil

Along with being respected for its antimicrobial properties, this oil has many medicinal properties as well. Let’s take a look at them below.

Treats Respiratory Conditions

Oregano essential oil can act as an expectorant, which loosens up or helps eliminate the uncomfortable buildups of mucus and phlegm in the respiratory tracts and sinuses. It is also a soothing balm for inflamed lungs and throat, which may often stimulate coughing fits. Therefore, oregano essential prevents and treats symptoms of respiratory ailments.

Anti-inflammatory Properties

This oil is good for soothing many types of inflammation, internal or external, caused by a variety of reasons. When it is applied topically, it can reduce redness and irritation onto the applied area and also relieve pain associated with arthritis or injury. When consumed, it has much of the same effect, although it is spread throughout the body, so will not necessarily relieve pain and discomfort as quickly.

Prevents Infections

Just as it protects you against viral infections, oregano oil protects you against bacterial infections as well. This gives you an additional level of protection against bacterial diseases such as infections in the colon and urinary tract, as well as typhoid, cholera, sores, skin infections, and food poisoning. Also, the antibacterial effects of oregano don’t have an inhibitory effect on the health, so you don’t suffer from the ill effects of being undefended.

Antifungal Properties

Viruses, bacteria, fungi, and protozoa are the four agents that are responsible for communicable and infectious diseases. Out of these, fungi are responsible for some of the most dreadful and fatal infections, both internal and external. They can cause ugly, painful, and deadly infections in the ear, nose, and throat, which, if not treated early, may reach the brain and become lethal.

Many skin infections are also caused by these fungi. Oregano oil, if used regularly, either internally or externally, can effectively protect the body against many of these fungal infections.

Prevents Viral Infections

Oregano essential oil provides protection against viral infections. This means that it strengthens your immunity against cold, mumps, measles, pox, and other problems caused by viruses. This boost to the immune system helps to defend against deadly viral infections and even autoimmune disorders. Oregano essential oil also stimulates the production and function of white blood cells, the body’s main line of defense.

Acts as Antiparasitic

Many types of parasites, such as roundworms, tapeworms, lice, bed bugs, mosquitoes, and fleas live inside or outside the human body. These parasites use the human body as a source of food and as a vessel or carrier of communicable diseases. Oregano essential oil, when ingested, can eliminate intestinal worms, and when applied externally, it effectively keeps away lice, bed bugs, mosquitoes, and fleas. Hence, it is not uncommon to find oregano essential oil as a component of organic bug sprays and repellents.

Prevents Cancer

This property turns out to be one of the most celebrated attributes of oregano essential oil because it protects you from the damages done to the body by free radicals (oxidants). It neutralizes free radicals while repairing the damage already done. This slows down the aging process and protects against certain cancers, macular degeneration, degeneration of muscle due to aging, wrinkles, loss of vision and hearing, nervous disorders, and many ailments related to premature aging and the effects of free radicals. More specifically, oregano essential oil contains phenols, a powerful form of antioxidant that eliminates free radicals that cause diseases and scours the body.

Regulates Menses

This powerful oil is beneficial for regulating menstruation and delaying the onset of menopause. Those suffering from obstructed menses may also find relief by using oregano essential oil. As an emmenagogue, it can help a woman reduce her symptoms of oncoming menopause, including mood imbalance and hormonal shifts.


This is another side of the sedative and anti-inflammatory properties of oregano essential oil. Allergies are hyper-reactions of the body towards external stimuli. Oregano oil, a sedative in nature, calms down this hyper-sensitivity and is known to give relief from allergy symptoms. Through its anti-inflammatory quality, the severity of allergies can be reduced, which is important for serious reactions like anaphylactic shocks or swelling in the throat.

Promotes Digestion

Oregano essential oil promotes digestion by increasing the secretion of digestive juices. It also increases the nutrient digestibility and enzymes which aid in absorbing food. This can improve your health by maximizing the nutrients you get from food!

Other Benefits

Oregano essential oil has been shown to help heal psoriasis, eczema, athlete’s foot, flu, and other infectious ailments. Furthermore, it can be used to treat bacterial infections like E. coli, giardiasis, and food poisoning. It relieves congestion, and certain studies also say that it is a powerful painkiller, with the added benefit that it works without having any strong side effects.

Oregano Essential Oil FAQs

What is oregano oil?

Oregano oil is a highly beneficial essential oil extracted from oregano leaves. While oregano is famed as a spice, oregano essential oil is a concentrated form that is widely sought after for natural remedies. You can use a steam distillation process on normal oregano leaves to get the pure essential oil, which can be used topically or consumed orally, depending on what ails you.

How to make oregano oil?

You can make oregano oil for yourself but the process is a bit lengthy. First, boil water in a saucepan or pot and then place chopped oregano leaves and a carrier oil into a glass jar. Carrier oils include olive, grapeseed or almond oil. When you place the jar into the hot water, the oil inside the jar heats up and releases the natural oil from the oregano leaves. Place the jar beside a sunny window for 2 weeks, shake it every few days, and then strain the resulting mixture.

How to use oregano oil?

You can topically apply oregano oil for skin irritation and in the space near wounds, as it can speed up healing. You can put oregano oil under your eyes and over wrinkles as well. You can also consume oregano oil as an additive, or in straight doses of roughly 500mg, 3-4 times a day, as a digestive aid. But remember, it is extremely potent and concentrated, so there is no need for an excess amount.

What is oregano oil good for?

Oregano oil is very important for human health and is impressively effective for the treatment of parasitic and fungal infections in many parts of the body. It is also an all-around immune system booster and can help improve digestion when consumed. It can help balance hormones and lessen the symptoms of menstruation, aid in weight loss efforts, and even minimize the severity of allergic reactions.

How to take oregano oil?

You can take oregano oil in supplemental form, meaning in a 500mg dose, or you can add small amounts of oregano oil to your food. It comes in capsule, tablet, and liquid form, and can be used topically, provided you dilute it 1:1 with olive oil. Oregano oil is very strong and concentrated, and should not be consumed or applied in large quantities. Capsule and tablet forms are recommended for this very reason.

Where to buy oregano oil?

You can buy oregano oil from any place where essential oils are sold, as well as major stores and big-box chains. It is relatively easy to prepare by yourself, although it takes a few weeks to fully make. Look out for it at natural health practitioners and herbalists, as well as stores like Walmart and GNC.

How to use oregano oil?

You can use oil of oregano in different ways, including topically for irritation on the skin and wound healing, sublingual consumption (dropping the oil beneath the tongue), adding it to certain foods, and even consuming it in a tablet or capsule form. Oregano oil is very useful for different health concerns and each method of using the oil is connected to what ailment you have. Speak to a professional who can recommend the best method!

Blending: The essential oil of oregano blends well with the essential oils of Lavender, Rosemary, Bergamot, Chamomile, Cypress, Cedar Wood, Tea Tree, and Eucalyptus. These combinations are often made and widely used by aromatherapists and herbalists.

Word of Caution: Oregano essential oil can cause irritation to the skin and mucous membranes if taken in high concentration or dosages. Pregnant women should avoid using it and should consult with a doctor before adding it in any significant way to the diet. Due to its ability to stimulate and regulate the hormones, it can potentially result in a miscarriage if the hormone that induces periods is stimulated. Also, like with any new dietary supplement or food, check with your doctor about allergies. People allergic to basil, lavender, marjoram, mint or sage are also commonly allergic to oregano and its essential oil.

I am a lover of Oil of Oregano, My favorite use is a few drops under the tongue and following with a glass or 2 of water or whatever drink. Amazing results!
Your feet are the "gateway" to your body, I also use in in combination with Frankincense, lavender, Clary Sage, Eucalyptus, and Coconut oil as a massage for my tired, achy feet, but it also soaks into your body, healing many fungus', etc...

+Jerome Valencia do you use it internally or externally?

I am wondering what the reason for applying to the bottom of the feet? I take internally in supplement capsule form which helps my asthma challenged pulmonary function.....

I presently use Entracare for my rabbits which is Aqua(water) & Oregano oil. Would this product provide me with the same componenets if I added water to it and what strength would I use?

Take it in capsule form. It's so potent smelling and it can get everywhere. I find it to be more effective when swallowed in a capsule as opposed to putting drops under your tongue. Trust me..capsules. I take Nature's Way. Work's great.

This works for really bad itching - scabies/mites (also toenail fungus) in my experience you should have good results and see much improvement within 1 to 2 days - Use 1 part extra virgin olive oil and 1 part oil of oregano, rub vigorously over all affected areas as needed before bed, or daytime also as needed. This diluted combo has never irritated my skin ever, not one time.

For toenail fungus apply every night the above combo over all nails (to reduce potential spreading), don't worry about sheets getting a little oily by your feet, you can change your sheets once a week, or lay a large towel down, or just wear loose socks to bed. Honestly the oil pretty much soaks in after 10 minutes anyways so no worries. I alternated nights only using extra virgin coconut oil all by itself. I went from having a nail that was totally ready to fall off, to generating a new healthy nail in about a month. I even missed a few days here and there and it worked very well

Does this eliminate intestinal infection?

Belinda Carrasco Henares

How do you use it? Straight from the pot? Or do I mix it with my cream or other oil? How do I take?

You can buy it at health food stores, its already mixed with a carrier oil so you can put a few drops in water to drink, or apply topically.

What about shingles? Will it help with shingles?


I am a 59 year old male and have had shingles since I was 19. Yes, Oregano oil can help with shingles along with lemon, tea tree and lavender. You can mix 50/50 with a carrier oil like olive or coconut and apply directly to the blisters, this will alleviate pain immediately. To take internally I use gel caps, 2-3 drops of each oil, 3 times a day. This works for me along with Organic ACV which you also apply directly to blisters. Hope this helps.

Can a six year old take it?

Not internally. I recommend topical use with a carrier oil for young children. I put in on the soles of my son's feet with coconut oil as a "carrier" oil... One drop per foot.

Meenakshi Nagdeve

Please consult your health specialist regarding usage by a 6 year old.

Can anyone tell me if there is a difference between Oil of Oregano and Oil of Oregano skin oil. Are they both the same thing? I am dying from the flu (not really but, I'm a man and I'm a bitch when I'm sick... lol) My GF picked this up for me but it says "skin oil" not for internal use? Is there two different products or one in the same?


The skin oil product most likely is diluted with other products and not made to take orally. Just like castro oil, the stuff in drug store you can use orally or topically, castor oil for skin and hair is topically only since its mixed with other things.

Bernadette Harrison

Mix up 2 tbspns organic turmeric powder with 500g jar of manuka honey @ 30+. Take 1 tbspns every 15 mins until feel relief. Exceptional as a natural anti biotics.

Does @30+ mean 30 drops of oil of oregano?

Information is good. The time and effort put forth are recognized. However, two things to point out as constructive feedback are: the ads are intrusive and annoying. I quickly lost motivation to continue reading. Second,roundworms aren't parasites. They're fungi. You may want to correct this.

The nematodes (UK: /ˈnɛmətoʊdz/, US: /ˈniːməˌtoʊdz/) or roundworms constitute the phylum Nematoda.[2][3] They are a diverse animal phylum inhabiting a broad range of environments. Nematode species can be difficult to distinguish, and although over 25,000 have been described,[4][5] of which more than half are parasitic, the total number of nematode species has been estimated to be about 1 million.[6] Nematodes are classified along with insects and other moulting animals in the clade Ecdysozoa, and, unlike flatworms, have tubular digestive systems with openings at both ends.

You're thinking of ringworm. Ringworm in the fungal infection, roundworm is the internal parasite.

Nadira, Meenakshi Nagdeve is absolutely right, round worms are indeed parasitic worms. Hence the word "worms" in the name. They are dangerous, as the cysts can migrate to the eyes and cause blindness. The video is very good. I hope this helps to correct your misconception.

They absolutely are not parasites but a fungal infection, many doctors have quit using the term because it isn't acuate, i have been treated for this myself so im speaking from experience, quit scaring people like that.

Meenakshi Nagdeve

Thanks crystalclear70!

Meenakshi Nagdeve

Thanks Nadira for your valuable comment
Roundworms are not fungi and they are indeed parasitic worms.

When used appropriately they are could be great pest control. Think outside the box, just because something SEEMS harmful doesn't mean there isn't a benefit to be derived from it.

I was a recreational user in my teens. Quit because I was told it was wrong.....not sure about that now...But I have son who uses it for medical reasons. It helps, and I would rather that then chemicals made by man.

I'm having digestive issues. I understand there are good & bad bacteria in the digestive track. How does oregano oil know which to eliminate.

Whitney Overstreet

IT DOESNT. A common side effect of MISUSING THIS VERY STRONG OIL is severe stomach upset, liver toxicity and can be LETHAL. Please don't take these oils internally.

I'm using it for my seborrheic dermatitis. It's very effective!

When I first herd about this, I thought that it was a crazy idea. Then I started taking it and it works better than anything out there that I have taken in the past. The common cold is cured with this stuff. Amazing! I'll take the bible cure any day.

I've found that Sambucol from the health food store works great to get rid of colds and the flu. A cold is gone in 24 hours and the flu in less than 3 days and you have hardly any symptoms. You take a tablespoon 4 times a day and when you are well, it stores in the frig for months and still works!

How much do you take? Does it come in so-many milligrams? How do you know what is the right dosage? Thanks.

If its a capsule look at the label, but with the drops that are already diluted with olive oil start with 3-4 drops a day when needed. I would use it everyday for no particular reason.

Clarissa Faith Lovehope

I am very sick from a protozoan infection I cant get rid of is there anything else besides this or a doctor to help?

What kind of protozoan infection? Hope this reaches you...


What kind of protozoan infection? Hope this reaches you...


I have used Oil of Oregano for 3 years and works great and alleviates sicknesses that are both viral and bacterial. Will not be without. Helps boost your immune system and eliminates invasive parasites in your system. Highly Recommend.

how many drops do you take? ... I have been reading that oregano is good for so many different things .... I have bacteria in my urine ... don't want to take antibiotics all the time ...

Standard: 6 drops; I take 10 drops in a vegetable capsule (it will burn through within' 15 minutes, so swallow immediately!).

10 drops in capsule? I take 3 drops in 1tsp of black seed oil or any good oil. 3 times a day between meals

One of my clients put some on a canker sore on her tongue and by the next day it was gone. I've begun taking 2 drops a day as of last week. I'll keep you posted!

I had athlete's foot (moccasin type) for 9 mos. , tried every over the counter cream, nothing worked. tried Oregano Oil & Olive Leaf w/70% Carvacrol.applied morning and night.rubbed a few drops on affected area.could see results first use! Been using 3 days and is much better, not gone but it's definately working.tried taking 30 drops in small amount of water and it burn/stingy my lips and mouth, (made me feel like puking)going to get capsules.read on other posts wont burn mouth.I think I should have started w/2-3 drops and not 30 (orally in small amount of water).

I dont suggest ANYONE TAKE 30 DROPS... EVER! I take just a couple every day... like two or 3

best to dilute in olive oil and put on a piece of bread but only 2 drops

It already comes diluted, but 30 drops is way too much. 3 drops is more like it.

You're preaching to the choir! Love this stuff for fighting throat infections. It tastes terrible, mind you, but it's worth the 3 minutes of unpleasantness while you choke back a few drops. I don't dilute it in juice, but put the drops directly down my throat. (Blech). But it works.

I put mine in a shot glass of orange juice, and toss it down... it works great. Cuts to burn and I feel it will kill any thing in my throat!

Hi Kait, I bought some for my husband's ailment.....for about $60.00! Sheesh! He won't take it so I will! Where can I buy it for cheap??? I have authritis troubles and a cough...It's not a cold. (Probably for smoking all those years..quit 2 years ago). Oh...sorry.."Puritan's Pride"....cool! Thanks.

You won't find a good oil for "cheap" sadly.

Whitney Overstreet

Lemme guess, you sell them?

Joanne Latimer --I think so, since it'll go to work on the virus that's making you sick in the first place. I get my oil from Puritan's Pride and it's super cheap--buy two bottles, get 3 free!

Good to know! Thanks Kait! I'll buy some today. You think they're as effective, since none of the oil actually touches the troubled throat?

Get gelatin caps from your local health food store. Fill them with your dose and swallow. The worst you have to deal with is a couple of oregano burps.

does oregano plant drive mosquito away.

I grow and extract my own oils from the fresh herb through steam extraction. It is an amazing oil and does really work with out fail.

Hey Jeff.....would you mind sharing the whole extraction process with me?

Dot O'Hara-Pinkham

Jeff Bent - what exactly is your recipe/process for this?

Marta Santos Lima

I have used oil of oregano - powerful!
