Oregano (essential) oil explained

oregano essential oil

Oregano oil is made from pressing the leaves and flowers of an oregano plant (part of the mint family). The oil is then distilled and can be used for a variety of different uses. However, not all oregano oil is created equal. Oregano is native to Europe but is grown on many different continents and in many different countries around the world.

In fact, there are over 90 different types of oregano! The best kind for producing oil is wild oregano. This type of oregano is called origanum vulgare. Another good kind is called thymus capitatus, which grows in Spain. So, when buying oregano oil for therapeutic uses, make sure you buy oil made from those types of plants.

Other oils wont have a good amount of nutrients, wont be properly distilled, or will not be made from healthy plants. As always, buy oils that are cold pressed, unrefined, organic and, if you can find it, fair trade.

This powerful oil is antibiotic, antifungal, anti-inflammatory, antiviral, antiseptic, anti-aging, antimicrobial, anti-parasitic… just about everything you can imagine! And with all these great properties come great uses.

Oregano oil uses

We would like to note that oregano essential oil is very strong and will need to be diluted for many of its uses as it can destroy some tissues when applied directly. Please take caution when using the essential oil. You will experience a painful burning sensation if this oil is not diluted properly.

If you would like, you can also buy a pre-diluted form of oregano oil, which is already mixed with another carrier oil (usually olive oil) to make sure you don’t damage anything you’re trying to fix!

Nail and foot fungus: Oregano oil’s amazing antibacterial properties make it perfect for fighting common nail and foot fungal infections.

Recipe: Dilute a few drops of oregano essential oil with 1-2 tablespoons of olive oil or grape seed oil. Simply apply this mixture to the infected area and leave the area unwrapped and in a cool, dry place.

Acne: Oregano oil can be used to treat and cure acne, malasezzia (a yeast infection in the skin that looks like acne), acne scarring, cystic acne or any other acne issue.


For spot treatments: Simply dilute OEO (Oregano Essential Oil) with carrier oil (for this, it is probably best to use a light carrier oil such as grape seed oil because some thick oils may also clog pores) and apply to the area. If you experience burning, remove the oil and further dilute the mixture until you do not experience pain.

For all-over treatments: Dilute the OEO much more and apply with a cotton swab. Again, if there is burning remove the mixture and dilute again. The suggested dilution is 6 parts carrier oil to 1 part OEO. However, everyone’s skin is affected differently. Re-apply this mixture 2-3 times daily.

Warts and moles: Warts and moles can be dangerous and unsightly. Remove them quickly and painlessly with oregano oil. This method is said to have very little to no scarring at all! It also only takes about 2 weeks to fully remove what you want to remove and for many people continues to keep the wart away for years!

Recipe: Apply OEO directly to the warts/moles. You can dilute it if it’s too painful, but most people just apply it directly. Cover the area with a band aid or cotton pad to protect and enclose it. You will feel burning but it should not be unbearable.

If need be, place a cold pack over the cotton pad to cool the burning sensation. You should only need to apply the oil once. The skin will be red, but within a week or two the warts/moles will dry up and fall off!

Cold sores: Oregano oil can also be used as a treatment for cold sores. It can be applied directly and does not have to be diluted, but it is recommended that you dilute it. Its extreme anti-bacterial and anti-inflammatory properties will go to work on the sore to shorten the length of showing time.

In fact, oregano was the most powerful of four essential oils (sage, ginseng, stevia) at killing all six different cancer cell lines tested, including cervical, breast, leukemia, lung, and colon cancer. How? It was discovered (surprisingly) that oregano almost completely depletes cancer cells of their glutathione—an antioxidant they need to survive. Without glutathione, cancer cells are highly vulnerable to oxidative stress and quickly die. “
