What is Oregano Oil?

Oregano is an herb that has been used in natural medicine for many, many years. You may have some experience cooking with oregano, but the oregano that we’re going to be talking about is not the same as what you would find in the spice aisle. The type of oregano that you would want for therapeutic benefits is called wild oregano oil.

Wild oregano oil is a very concentrated liquid. The oregano plant, including the leaves and stem, is put through a steam distillation process that extracts the essential oil from the herb. It takes over 200 pounds of wild oregano just to make two pounds of wild oregano oil.

When used for therapeutic or medicinal purposes, wild oregano is also sometimes called “oregano essential oil” or “oil of oregano.” This oil has three very powerful phenols or phytochemicals that have some really interesting and powerful properties.

These unique phenols are:


Research suggests carvacrol may have the ability to stop the growth of many different types of bacteria.


Thymol has natural antifungal properties. It may help support the immune system and protect against certain fungal infections.

Rosmarinic acid

With its powerful antioxidant properties, rosmarinic acid may help protect against free radical damage.

14 Amazing Oregano Oil Benefits

A big problem in healthcare right now something called antibiotic resistance. A person can develop antibiotic resistance from the chronic use of antibiotics. Antibiotics are being overprescribed and often abused. Yes, antibiotics can be a good thing in certain situations, and I’m not suggesting you go against your doctor’s orders in taking them. I’m also not giving you any medical advice. But, it’s something you may want to research and talk to your doctor about if you’re prescribed antibiotics.

The big problem with antibiotics, in general, is that they not only kill off the bad bacteria that are causing infections, but they also they kill your good bacteria that are essential for a healthy body. This can potentially create a cascade of different health problems.

The overuse of antibiotics can make them less effective against the harmful bacteria they are intended to treat while they still wipe out the friendly microbes (probiotics). Your friendly microbes have many different important functions, including producing certain vitamins, supporting digestion, and protecting the body against infections.

Considering all of the health benefits of oregano oil, it may make a fantastic natural alternative to antibiotics. Dozens of studies suggest that the active ingredients in oregano oil may help protect your health and fight against certain harmful pathogens, including yeast, fungi, and bacteria.

How to Use Oregano Oil

Whether you use oregano oil topically or you consume oregano oil, it’s important that you start slow. Consider taking advantage of these oregano oil benefits, but ease into it gradually and see how your body reacts, then you can use more if needed.

Some of these harmful microbes can have endotoxins within them. When you kill these microbes, the endotoxins can be released and can stir up an immune reaction. You should really take it slow with any herb or natural remedy that you use.

If you use oregano oil topically, you can mix it with a carrier oil like olive oil or coconut oil so that the potent oregano essential oil won’t cause any skin irritation.

There are certain high-quality wild oregano oil capsules or pearls available that you can take orally. As far as dosage, I would follow the dosage directions on the label, but like I said, always start small.
