Impressive Oregano Essential Oil Uses for Immunity

Oregano essential oil uses are potent, so read on to learn more about how to use this wonderful, concentrated form of oregano.

Will Oregano Essential Oil Change Healthcare?

We can’t keep potent plant essential oils like oregano a secret.  We need to help each other.  I’m here to help you. Then you can help the next person by telling your story.

Health care is based on stories and experiences, that is, up until Big Pharma decided it should be something different. Let’s not kid ourselves.  Huge trials of clinical research are almost exclusively funded by them.

Small studies still manage to surface due to the virtues of great scientists, but usually don’t have funding to take them further.

Oregano essential oil has never failed me. Never.  I’ll get into more of this and why it is so potent.

I want to explore the topic of immunity with a broader lens before I do that.  Right now, healthcare is more expensive than ever.  And drug-resistant infections are no small contributor to this expense.

Every day I hear how people can’t afford their prescriptions and even worse, they aren’t feeling healthier.  We have largely abandoned tools that the earth has given us for name-brand drugs with pink shiny coating on them.  “Name it to tame it” then throw a pill at it.

While some prescription medications are absolutely necessary and save lives, they don’t touch the broad category of immunity at all.  This is why I am now bold enough to tackle oregano essential oil uses. This, as you may know by now if you read my blogs, starts in the gut.

Oregano addresses almost everything our immune system requires when acute illness sets in.

Using Oregano Essential Oil at The First Signs of Illness

Have you ever felt a wave of nausea and stomach pain overcome you and you KNOW that you are going to be down for days with vomiting?

I’ve felt this, but I have oregano essential oil.  It is REALLY strong and it REALLY works.

About a month ago, this happened to me.  Here is the key.  I didn’t wait 5 minutes.  I grabbed 3 drops of oregano oil, added it to 8 oz of water, and gulped it down RIGHT away.  And I gulp it fast because it is STRONG!

What happened?  One minute later, the stomach pain was gone and so was the nausea.  Gone. This has happened to me at least 20 times for various illnesses setting in over the years.  The second I start feeling sick, I grab the oregano and it always helps super fast.  Needless to say, I don’t take sick days ever!

At the first sign of a cold, sore throat, or other malaise, what do I do?  Grab Doterra oregano essential oil stat!

And it works for me every time.

But, you may be asking yourself right now, am I imagining it all?  Would I have gotten better anyway?  Perhaps, but perhaps not.  And my track record is very good.

Let’s take a look at what we know about oregano, and you can answer that for yourself.  Then, let’s review what you need to know before embarking on adding oregano oil into your life.

Oregano Essential Oil Uses Overview

Oregano essential oil kills over 90 known strains of bacteria, fungi, viruses, molds, and parasites! Why do I talk about essential oil for medicinal purposes instead of fresh oregano?

Essential oil is a very concentrated form of the medicinal parts of the plant that has been used for hundreds of years.

Essential oils are often 30 times more concentrated than the original plant.  We need this in times of illness.

How much does Certified Pure Therapeutic oregano oil cost per dose? $0.29 cents per dose (3 drops).  Think how much money, time, and agony you could be saving.  You can have it in your home and your car AND your purse at all times for much less than the cost of a doctor’s visit.

Don’t skimp and buy the inferior kinds at the grocery store or so-called “organic” either.  They can be laden with chemicals!  I will explain why.

Oregano Essential Oil Antiviral Effects

Norovirus is a nasty virus that causes nausea, vomiting, and diarrhea.  It is exceedingly common for people.

Enter oregano essential oil use.  A substance in oregano oil called carvacrol reduced the replication and growth of norovirus within an hour in cell study and on surfaces.

Oregano oil kills many other viruses too.  These include acyclovir-resistant herpes simplex virus type 1, acyclovir-sensitive HHV-1, human respiratory syncytial virus, bovine herpesvirus type 2, and bovine viral diarrhea virus.

Many people successfully treat warts, a type of virus, with diluted topical essential oil when applied three times daily.

What prescriptions are antiviral? Very few, and you have to go to the doctor within a very narrow window of exposure.  This is a very expensive trip! And often, you will be too late.

Oregano Oil Antibacterial Actions

It’s not just viruses that oregano is able to fight.  Oregano essential oil fights nasty bacteria too.  A cell study found that oregano oil was effective against all tested strains of bacteria, including gram-negative bacteria and gram-positive bacteria.  This included dangerous e.coli.

Oregano essential oil use inhibits E. coli Proteus and Pseudomonas bacteria.  This makes it a very effective remedy for both urinary tract infections (UTIs) and prostatitis or some forms of enlarged prostate.

Small Intestinal Bacterial Overgrowth (SIBO) is a common condition that results in a lot of pain and food intolerance, to name a few.  Often, SIBO is resistant to current antibiotic therapy as well.

Oregano oil was as effective as triple antibiotic therapy and had MUCH fewer side effects for people with SIBO-resistant disease.

Oregano destroys MRSA on surfaces.  It also has been used in creams to help effectively treat MRSA infections in a small clinical trial.

Another fascinating role for oregano against bacteria:  oregano oil compound carvacrol reduces the growth of excess bacteria of iron therapy for anemia in a cell study.

Bacterial overgrowth is a common side effect of iron therapy or iron overload.

Oregano Oil for Fungal Infections

Fungi turn out to be no match for oregano either. Five disease-causing strains of fungus were reduced by oregano oil in a cell study.

Oregano oil use is also VERY effective against an athlete’s foot type of fungus.  In fact, it was the most effective treatment for an athlete’s foot in a clinical study.

Candida also may be effectively treated with oregano essential oil.  Even more importantly, oregano essential oil helps fight fluconazole-resistant forms of candida infections.

Oregano Essential Oil for Parasites

Oregano may also help fight intestinal parasites that are very difficult to treat. Blastocystis hominis, Entamoeba hartmanni, and Endolimax nana were either reduced or eliminated after 6 weeks of oregano essential oil use in 14 people with parasitic infections.

Summary Benefits of Oregano Essential Oil

Oregano may also help protect the body from cancer and reduce inflammation due to its immune benefits.  Let’s review:

What can antibiotics do?

Selectively kill certain strains of bacteria. Broad-spectrum antibiotics wipe out essentially all bacteria.

What can oregano do?

Kill over 90 strains of pathogenic bacteria, viruses, fungi, AND parasites.  Oregano for the win.

It appears that oregano can do pretty much everything except the dishes.

Oregano oil is not meant to be a replacement for drug therapy when needed.  It is a nice tool that is available for you at home to try safely on occasion.

Safe Ways To Use Oregano Essential Oil

Internal Use

While I do love the flavor and use it all the time, all the research so far is dedicated to oregano oil because it is a VERY concentrated form of oregano. This is what is needed in times of illness.

A few sprigs of fresh oregano may not have medicinal effects acutely.

Only buy and use  Certified Pure Therapeutic Grade (CPTG) oregano oil. Even so-called organic types of essential oil can be processed with dangerous chemicals like hexane! Many of these oils disguised as “pure” can have solvents and chemicals that are bad for you.

You may also add drops of CPTG oregano oil to an empty gelcap and take them internally.

If using oregano essential oil for treating illnesses, make sure to use higher doses for only 10 days or fewer.  Small, frequent doses work better than large doses.  Try 3 drops orally 3 times daily when feeling ill.  Always dilute in water or take in an empty capsule.

For health maintenance, you can take 1 drop in a capsule daily.

While the flavor of CPTG on itself is very strong, adding it to olive oil can temper it very quickly.  It tastes great as a dip or sauce for food!

Topical Use

Always dilute oregano, both topically and internally!  If using topically, dilute with fractionated coconut oil and apply to the area of concern.

Oregano essential oil used on surfaces is greatly used to help disinfect your home naturally and to reduce the chemical load in your home.  For molds and for surface cleaners, simply add 10 drops per 16 oz glass spray bottle.  Shake before using.

Diluted oregano oil (with coconut oil) may be placed on a cotton ball and rubbed around the ear to help ease ear infections.

Make sure to avoid using it topically if you have a sensitivity to oregano oil or develop a rash.


Diffuse oregano oil 2-4 drops to help keep the air healthy in your rooms at home.


Always seek medical help for emergent health conditions, and as always, discuss your healthcare options with your practitioner.  The use of oregano essential oil is not recommended when pregnant.
