Oregano Oil Treatment for SIBO? – Everything You Need to Know About This Natural Antibiotic!

Unfortunately, not many people know that Oregano oil is not only useful in the kitchen but it has many medical uses as well!

Oregano is a natural antibiotic which is why it’s a great home remedy for a number of different symptoms and illnesses, including bacterial infections.

In fact, it is particularly great for those who struggle with SIBO and other similar gut problems so don’t hesitate to try it out if this is you.

That being said, this article is here to teach you everything you need to know about oregano oil as well as provide you with some great products and links to where you can order them on Amazon.

This way, you’ll be able to make an informed decision before buying this miracle herb and hopefully find relief for your gut problems as soon as possible.

How Does it Work?

Oregano, especially in its dried form, can be found on most spice racks out there since it’s such a versatile ingredient in the kitchen.

As mentioned before, however, this seasoning can also provide people with a bunch of health benefits due to the fact that it is categorized as a natural antibiotic.

More precisely, you will find that when it comes to its medical properties, oregano is much more effective in its oil form rather than as dried leaves so it’s not enough to just make sure you include the spice in your meals.

Oregano oil has been getting more and more popular lately and it’s no surprise as to why that is!

This miracle ingredient is great for those who struggle with bacterial infections.

And even though its properties are just now getting more attention, oregano has been used as a remedy for thousands of years in many different cultures.

Its main active ingredients are carvacrol and thymol.

Carvacrol is a compound that acts like an antibacterial, fighting a variety of bacteria strains including E.coli, Salmonella, Bacillus, Enterococcus, and Pseudomonas.

Not only that but oregano oil is also quite efficient in fighting both methicillin sensitive and methicillin resistant Staphylococcus aureus (MRSA) strains.

Not to mention that Carvacrol is also believed to do far less damage to the microbiome when compared to conventional antibiotics.

Finally, carvacrol is just as efficient in fighting Candida (yeast infection) and even some viruses.


At this point, it is probably clear enough just how great oregano oil is when it comes to fighting fungal, bacterial and even viral conditions.

So, here is a comprehensive list of some of the problems it’s good for, including those mentioned before as well as others:


– Bacterial infections

– Dysbiosis

– Yeast infections

– Seasonal cold

– The flu

– Ear infections

– Sinus infections

– Urinary tract infections

– Sore throat

– Bug bites,

– Rashes

– Poison ivy

Oregano Oil v. Pharmaceutical Antibiotics

Whenever you need to take any sort of antibiotic, it is normal that you have questions and worries as far as overuse and the possible damage to the good bacteria are concerned.

With that being said, how can oregano oil be compared to the usual antibiotics available on the market?

More precisely, is there an equally high risk that it will affect the good bacteria in your system while fighting bad bacteria and infection?

The answer is quite clear; no matter the natural product, if it’s proven to have the same beneficial effects as the pharmaceutical equivalent, it is always the better choice.

This is the cause due to the fact that natural products such as oregano oil will usually be gentler than prescription drugs on your microbiome, not doing nearly as much damage to the healthy gut bacteria.

The gentler mechanism means a lower risk of suffering from adverse effects patients often experience when they resort to taking prescribed antibiotics.

Some of the most common side effects are: abdominal cramping, nausea, vomiting, and diarrhea but you’ll find that there are other, more serious ones you may have to deal with as well.

They are: the Steven-Johnson syndrome, severe allergic reactions, tendonitis and an irregular heartbeat.

The even better news is that oregano oil is indeed amongst those natural remedies that have been shown to be just as effective as regular antibiotics in many cases.

Just keep in mind that while it’s clear a high dose of oregano oil does wonders as an antimicrobial, there is still a lot of clinical research to be done on this topic so it’s not 100 percent certain it does spare the good bacteria.

At the same time, there is sufficient animal research, more often than not involving lab rats, that show oregano oil is quite effective.

Besides, to ensure that you don’t cause havoc to your good bacteria, either while taking oregano oil or prescribed antibiotics, you can eat things like fermented foods and yogurt since they encourage the re-population of healthy gut bacteria.

Why Oregano Oil Can Be the Better Choice

Overall, the general consensus seems to be that oregano oil, being a natural product made from a variety of different compounds, is less harmful to the gut when compared to pharmaceutical antibiotics.

But whether that is really the case or not, it’s at least just as efficient so at the end of the day, you can’t go wrong with it.

What’s certain is that pharmaceutical antibiotics are really strong and tend to attack all bacteria, both good and bad.

The good bacteria, if you did not know, it’s there to aid in digesting food, support immune health, provide different nutrients for the body and even help regulate our mood!

Pharmaceutical antibiotics contain only one compound, which means it is easier for bacteria to evolve and adapt to them, becoming resistant!

This obviously means that the antibiotic will end up becoming inefficient after repeated use.

On the other hand, oregano oil contains a number of different compounds, causing bacteria to struggle to adapt to it and helping the patient avoid antibiotic resistance in the long run.

All in all, if you are seriously considering using oregano oil to treat things like SIBO or any other bacterial infection, rest assured that it is a great choice.

Potential Side Effects

Even though it appears to be really safe and efficient, it’s still a good idea to explore the potential side effects that may come with the use of oregano oil.

After all, this means that we can have some extra peace of mind or that we are prepared for anything and can make an informed decision before using this natural product.

Despite the limited medical research, it is well known from traditional use that oregano oil is quite a strong and potent natural antibiotic.

Taking any normal amount of it for short periods of time is not considered dangerous in any way but, like with anything else in the world, overdosing on it can still cause some issues.

Moreover, it is not normally recommended to take oregano oil every single day, unless you use it while under the care of a medical expert.

Therefore, you should keep in mind that oregano oil capsules are highly concentrated products as compared to the common dried oregano we all like to use in our cooking.

This means that you should always avoid taking too much of it since it is so strong and could, indeed, cause some issues such as:

– Gastric distress,

– Nausea,

– Vomiting,

– Gastric burning,

– Tissue irritation,

– Possible destruction of the good bacteria in your gut.

In addition, it is also corrosive to the eyes and skin so be careful never to use it on broken skin or near the eyes.

To avoid any issues, make sure you only use oregano oil treatments for a short period of time and never go overboard with the dosage.

Studies do seem to suggest that if you use this strong herb in large quantities, it can, indeed kill good bacteria just like pharmaceutical antibiotics do.

Treating SIBO?

Practitioners tend to use oregano oil to treat SIBO quite often thanks to its strong antimicrobial properties.

In case you are not aware, SIBO stands for “small intestine bacterial overgrowth” and refers to when there is too much bacteria accumulated in the small intestine.

This overgrowth of bacteria in that area leads to a number of different symptoms such as bloating, gas, diarrhea, constipation and more!

SIBO is usually caused by one of the following medical issues:

– Structural issues in the bowel

– Slow movement in the intestines

– Malnutrition disorders

– Malabsorption disorders

– Fixing underlying issues causing slow motility

– Drugs that impair motility or GI function

– Immune system dysfunction

Common treatments for SIBO:

– Prokinetics

– Probiotics

– Dietary changes

– Elemental Diet

– Antibiotics

– Oregano oil


In general, most people recommend starting with 200 mg capsules 2 to 3 times a day and to also take them with meals to ensure they are as gentle as possible on your stomach.

You should see results anywhere between 1 and 3 weeks but in some cases, it may take between 4 and 6 weeks to find relief for your symptoms, especially if you’re trying to get rid of something like SIBO.

With that being said, keep in mind that if you do not see results during this time frame, you should probably stop since taking oregano oil is not recommended for more than a few weeks.

This is because prolonged use can cause significant damage to the microbiome due to the fact that oregano oil has a really strong antimicrobial effect.

As mentioned throughout this guide, the research on the benefits of using oregano oil is still quite limited but the more scientists focus on it, the more we’ll learn about its many uses as an alternative to pharmaceutical antibiotics.

To make taking it even easier and safer, here are some recommended dosages depending on what you wish to combat!

– SIBO: 200mg capsules 2 to 3 times per day for a maximum of 4 to 6 weeks.

– Sore throat: 200mg capsules 2 to 3 times per day for 7 to 10 days.

– Infections: 200mg capsules 2 to 3 times per day for 7 to 10 days.

– Seasonal cold and the flu: 200mg capsules 2 to 3 times per day for 7 to 10 days.

Ways to Take Oregano Oil

The most common ways to take oregano oil are in capsule or liquid form, although there are a few other less known forms.

If you pick the liquid form, you should also take a so-called “carrier oil” with it, such as olive or coconut oil.

The reason why this is necessary is that it aids with oregano oil’s absorption.

More precisely, you should dilute the oregano oil to a 1:1 ratio with the carrier oil, no matter which one you prefer.

Usually, one or two drops of your mixed oils is enough for one use and the way you should take the mixture should be by putting the drops under the tongue and waiting for a few minutes in order to let them get absorbed really well before finally rinsing your mouth out with water.

Furthermore, to fully benefit from this natural antibiotic, you should choose a carrier oil that is standardized to at least 55 to 70% carvacrol and also take about two drops twice to four times per day.

However, if you prefer to take the oregano oil in capsule form, all you have to do is check the recommended dosage instructions that come with the product. Usually, it’s 200mg, three times a day.

This is obviously the most straightforward way to take oregano oil since all you have to do is take the capsule along with some water, swallowing it whole.

The oregano oil capsules dosage is 200 mg 3x per day
