I love lavender for being so mild, but oregano is the opposite… it’s incredibly powerful and strong! This wonderful herb has many benefits and health-promoting uses around the house.

Oregano: The Delight of the Mountain

Oregano (Origanum vulgare) is an aromatic and slightly bitter herb in the mint family. The name is derived from Greek meaning “mountain of joy” or “the delight of the mountain.” It grows naturally in warm, dry climates (it’s native to the Mediterranean) but is cultivated in many places in the world today.

Oregano is a very flavorful herb that is often used in Italian, Greek, and Spanish cooking. It is often used in seasoning blends, including Italian seasoning, and pairs well with meats, tomato dishes, and eggs. I always add it to my homemade soups and stews, especially during illness, as it is said to have antibacterial properties.

But the benefits of oregano leaves go far beyond the kitchen!

Oregano Herb Health Benefits

Oregano has been gaining popularity as a natural remedy, though its use as a health-boosting herb is centuries old. Modern science confirms the reasons for this: it contains high amounts of omega-3s, iron, manganese, vitamin K, and antioxidants.

Oregano essential oil is well known in natural health communities for its antibacterial properties, and it is even being studied by the mainstream medical community for its potential health benefits.

High Level of Antioxidants and Anti-Inflammatory Properties

Like the fresh herb, oregano oil has very high amounts of antioxidants that help fight free radicals. These antioxidants include:

  • phenols
  • triterpenes
  • rosmarinic acid
  • ursolic acid
  • oleanolic acid

Because of its antioxidants, oregano oil is protective against damage from some medications, according to a 2015 study.

One 2007 study found that a combination of oregano and thyme essential oils could lower production of pro-inflammatory cytokines. Because if this, the essential oil mixture may be helpful in reducing symptoms from inflammatory illnesses like colitis.

Another study published in the journal Experimental and Toxicologic Pathology found that oregano oil could lower the negative effects of induced colitis in rats and opens the door to new ideas about its benefit to the colon and liver.


Oregano has many antimicrobial properties including antibacterial and anti-parasitic.

A recent study from the Department of Physiology and Biophysics at Georgetown University Medical Center stated that new (safe) antimicrobials are needed to prevent and treat infections and that essential oils like oregano essential oil may be the answer.


In an article published on Science Daily, oregano essential oil was found to be effective in killing Staphylococcus bacteria. It was also equally as effective in its germ-killing abilities as common prescription antibiotics.

Helps Fight Parasites

One study published in Phytotherapy Research found that adults suffering from parasites had significant improvements in their digestive symptoms after using oregano oil.

Helps Athletes Foot

Oregano is also antifungal. One study found that of the 11 essential oils tested, oregano was the most powerful against athlete’s foot. Combined with salt and heat, researchers concluded that essential oils (specifically oregano) were a promising treatment.

Boosts the Immune System and Fights Cancer Cells

According to a 2013 study, oregano and other herbs in the Lamiaceae family can help stimulate the immune system. This might explain the traditional use of oregano for treating illness. But oregano is more than an immune stimulator. A study published in Cancer Letters found that a compound in oregano looked promising as a potential cancer cell killer in prostate, breast, skin, leukemia, and colon cancers.

Oregano Oil, Oregano Essential Oil, and Oil of Oregano: What’s the Difference?

This can be a confusing topic! Often when people talk about oregano they use these terms interchangeably. But each one is slightly different. Here’s how:

  • Oregano oil is oil (often olive oil) that is infused with oregano. This oil may be used medicinally but is most often used culinarily.
  • Oregano essential oil (like all essential oils) are distilled from plant matter and are incredibly concentrated.
  • Oil of oregano is a prepared dilution of oregano essential oil. This can be purchased already prepared but you can make your own too.

Essential oils should never be used (especially ingested) undiluted. Whenever ingestion is mentioned, oil of oregano is what you want to use. Topical use of oregano essential oils should also be diluted.

How to Use Oregano

Oregano has many uses around the home:


Dried or Fresh Oregano Uses

  • It can be consumed as an herb in culinary uses, a tincture, tea, or diluted essential oil.
  • Dried oregano, in combination with other dried herbs like basil, rosemary,  and thyme, can create an effective facial steam for loosening congestion and calming coughing.

Oregano Essential Oil Uses

  • The diluted oil can be consumed to speed recovery during illness.
  • Oregano essential oil (diluted in coconut oil) can be used on skin infections to boost healing.
  • It can be mixed into coconut oil as part of an oil pulling routine for healthy gums.
  • Diluted in a carrier oil, oregano essential oil taken internally can help with allergies.
  • Oregano essential oil diluted in olive oil can be rubbed on sore muscles and joints for pain relief.
  • It can be diluted for effective use on athletes foot and fungal infections.
  • Diluted oregano EO can be helpful in ridding the body of ringworm when used topically.
  • It can be effective in removing warts when used diluted on the skin.

Because oregano has such strong antimicrobial properties, it can help with many infections both internal and external.

Where to Buy Oregano

I typically purchase dried oregano in bulk online. My oregano essential oil comes from here.

Another way to get the benefits of oregano is to grow it fresh! All it takes is a small herb garden or window box.

Some growing notes:

  • Oregano likes warm, dry climates, and full sun.
  • Buy from seed or get instant gratification and purchase seedlings.
  • As they grow, pinch off leaves to encourage a bushier plant.

Harvesting oregano is also simple. Harvest the leaves as you need them and dry some for storage.

Is Oregano Safe?

Oregano oil is not generally considered safe during pregnancy, though culinary use of oregano leaf is considered fine.

If you meet any of the following conditions, talk to your doctor before use as oregano may not be safe for you:

  • allergies to plants in the Lamiaceae family
  • bleeding disorders
  • diabetes
  • planning a surgery

Due to its highly potent nature, oregano essential oil should always be diluted for use on the skin or when taking internally. I am not a doctor or medical professional, and you should always consult your doctor before taking any herbs or beginning any health routine.

    Everyone PLEASE take the diluting of oregano essential oil very serious! Oregano essential oil burns are NO JOKE!!!!! Please don’t repeat my mistake. I thought I was going to have to end up going to the hospital for a few days there(but held out because I was so embarrassed) and I have a big scar on the back of my neck.
    Sincerely, the lady who’s giving you the chance to learn from her dumb mistake so you don’t have to learn from your own.

    My herbalist said she would never recommend taking oregano oil internally for parasites. It is too strong and would kill off beneficial bacteria.
