Oregano oil has been found to have powerful antibacterial properties and is even effective against bacterial strains which are resistant to antibiotics, such as MRSA.

It is often referred to as “nature’s antibiotic“.

The way oregano oil acts is very unique because it reduces the density of the bacterial cells, which makes them vulnerable to attack from your white blood cells. This also means that the cell’s metabolism can be affected, making them less able to breed.

Oregano oil is highly effective fighting yeasts and fungi due to the same mechanism, which stops them breeding and spreading.

It is perfect for all sorts of bacterial and fungal infections, and a great preventative measure when it comes to protecting wounds from infection.

Cinnamon Essential Oil is very powerful and useful in fighting illness


Cinnamon has long been noted for its health benefits and is amazing as an antibacterial agent which will protect you against bacterial infections and even fight them off.

Research has found that cinnamon essential oil can heal infections in wounds, the mouth, and on the skin, making it impossible for serious infections to develop.

You will want to use food-grade cinnamon oil, as you will most likely be applying it to an open wound or the mouth, where it is very likely to enter your bloodstream.

Tea tree oil is one of the best topical antibacterial remedy nature has to offer.

It is excellent for fighting E. Coli and staph infections, as well as for preventing the spread of infectious diseases.

Applying it to your skin will immediately kill almost every single bacterial and viral cell there, and will continue to suppress them for an entire day.

This means that if you are living with someone who is ill, or if it’s the middle of cold and flu season, you can reduce your risk of illness by rinsing your hands with tea tree oil and water twice a day.

What is more, as many chest colds and digestive tract infections are prolonged because we keep reinfecting ourselves as the bacteria are living on our skin, which then lets them get into our food, onto our bedding and clothes, and back into our bodies.

Tea tree will naturally kill these surface bacteria.

If we use tea tree oil to wash our hands, a few drops in our laundry or in water to spray on our bed, and to keep our fridge clean, we can reduce the amount of reinfection and help our bodies recover sooner.

Clove essential oils are powerful for helping fight illness


The clove tree, Eugenia Car, is a source of three different types of essential oils depending on where you take it from in the plant.

The flower and bud can produce the clove oil we are all quite familiar with, but the tendrils and the leaves can produce their own distinctive oils which are also excellent antibacterial, antiviral, and antifungal remedies.

Clove oil is actually antiparasitic too, killing off most strains of worm infection and deterring many ticks, fleas, and flies from biting us.

Clove oils can be used as a complementary form of medicine when treating lung conditions such as bronchitis, throat infections, and even severe chest infections.

Clove oil is best used in a diffuser or applied to the skin.


Thyme oil is a highly underrated essential oil, probably because we tend to think of it as a mild herb and not a powerful medicine.

It is a powerful compound and should not be used directly on your skin, as this can cause sensitization and irritation. It must first be diluted with a carrier oil (like olive oil, coconut oil, or almond oil), and it’s a good idea to test it on a small area first to see if you have any allergies.

Thyme oil can be used in a variety of ways. It can be inhaled, applied topically, or used as a mouthwash.

Relieve pain – Mix three drops of thyme oil with two teaspoons of coconut oil. Use this mixture as a massage oil and apply it to your abdominal area to relieve pain. This may also be used as a massage oil to treat other types of pain, including insect and animal bites and stings.

Promote oral health – Use thyme oil as a mouthwash by adding one drop to a cup of warm water.

Treat or protect against respiratory problems – Add two drops of thyme oil to hot water and use for steam inhalation.

Bay Laurel Essential Oil Uses


Bay Laurel is highly beneficial in essential oil form and is notoriously good for fighting off viral infections.

It is primarily used topically in a massage oil or in a diffuser.

Its effects, however, may vary depending on the amount you use. Higher amounts of Bay oil may produce a sedating effect, while smaller amounts can serve as a stimulant.

Treat flu symptoms by adding 3 drops of Bay oil to a diffuser.

Treat dandruff by adding 2 drops of Bay oil to your shampoo.

How To Use Antibacterial Essential Oils

There are 4 main ways to use your essential oils. 


The first and most obvious application of antibacterial essential oils is to use them topically on wounds.

Do not apply neat essential oils to your skin without testing them, as this can cause harm to your own cells and provokes irritation in many people.

On wounds mix a few drops of essential oil into warm water and use it to lightly wipe the wound clean.

You can also use a syringe (the type without a needle!) to spray water with essential oil into a particularly messy or deep wound before adding butterfly stitches or bandages.

In most cases, a carrier oil like coconut oil or almond oil will decrease your chances of being irritated by the oils but will not dimish their effectiveness.

An exception to this is tea tree oil. If you can take a couple of drops of tea tree oil on your skin without a problem, sometimes you can rinse wounds with straight tea tree oil.


If someone you know is sick then you can make sure everything is disinfected by mixing a 30% essential oil, 60% warm water, 10% rubbing alcohol mix and spraying everything with it.

Make sure to spray clothes and bedding before washing, and to let the spray dry out before washing them, as you want the bacteria, parasite eggs, fungus, or virus to be dead before you wash away the essential oils.

This is also great for things you can’t wash easily, like a mattress, carpet, or curtains.  Get my DIY Fabric Spray Recipe Here.


You can diffuse oils in your home with a simple diffuser that is easy to find on Amazon.

I’ve purchased several for under $20 and have been using them for over a year with no problem.

Simply add a few drops of oils to your diffuser to sanitize or clean the air.

How To Use Essential Oils For A Cold


If you purchase food-grade essential oils, you can use them as medicines for internal illness or infection.

A small dose of oregano essential oil in water or tea can sometimes be the only thing that helps fight back against a viral infection.

Using food-grade essential oils can help prevent, eliminate, and heal from cases of food poisoning by killing the bacteria responsible.

Essential Oils are so powerful. Just a few drops of geranium oil has many benefits.

What Brand Of Essential Oils I Use

I own several different brands of essential oils.

I have a stash of Young Living, Doterra, Plant Therapy, and Now brands.

The oils I purchased in the last 6 months have been from Isagenix and Simply Earth.

I use different brands depending on my needs and you should do the same.

Always, always do your own research and consult a professional if you are concerned especially if you plan to ingest your oils.

A Word Of Caution

Although essential oils can be amazing for us, you still need to be careful about what you do.

First of all, never consume essential oils which are not food grade, even if the thing they are made of is something you normally eat.

For example, cinnamon oil may be safe to eat, but if it is not food grade it may be too intense to consume.

If you want to be really safe, exclusively buy food grade essential oils.

Secondly, never apply essential oils of any variety directly to the inside of the nose, urethra, vagina, or anus, as this can cause irritation.

Essential oils tend to have a powerful drying effect, which is great for removing grease from our skin and helping wounds heal. But this same effect is disastrous if it hits a part of our body which is supposed to be always humid.

If you take the moisture away from the inside of our nose, urethra, vagina, or anus, you can make the thin tissues of that area tighten and crack, causing bleeding and increased risk of infection.

Please consider other treatments for injuries or infections in these areas.

Finally, you need to be confident that the oil you purchase is exactly what it says on the label: a pure plant extract, from that specific plant, food-grade if that is what you ordered.

Do not buy obscure brands from the internet

Stick to brands you know and trust, and always look for certification that the oils are safe and toxic-free.
