Oil of Oregano: A Small Bottle with Big Botanical Benefits

By Dr. Aisha Hill-Hart | The Active Herb

Oregano isn’t just for seasoning your favorite meals. When extracted and formulated correctly, it becomes a concentrated herbal powerhouse known as Oil of Oregano—a staple in many natural wellness routines for seasonal support, balance, and gut-focused rituals.

But it’s important to note: not all oregano oils are created equal. If you're looking for a form that’s safe to take internally, you’re likely thinking of Oil of Oregano, not oregano essential oil. Here’s what makes the difference—and why quality matters.

What Is Oil of Oregano?

Oil of Oregano is a diluted preparation made by combining oregano essential oil (steam-distilled from Origanum vulgare) with a carrier oil such as MCT oil or olive oil.

This form is:

  • Safe for internal use when following proper guidelines

  • Pre-diluted for sublingual or oral use

  • Rich in key plant compounds, particularly carvacrol, known for its potent bioactivity

Carvacrol is the main component responsible for oregano’s antimicrobial and antioxidant effects observed in lab studies. It typically makes up 60 to 80 percent of the oil.

Why Do People Use It?

Oil of Oregano has a long-standing place in traditional wellness practices. In contemporary settings, people often use it:

  • During seasonal changes

  • As part of gut health protocols

  • For occasional microbial balance support

  • In wellness resets or cleanse routines

While it is not a drug or a cure, laboratory studies have shown that carvacrol and thymol—two major constituents—can inhibit the growth of certain bacteria and fungi in vitro, and may disrupt biofilm formation.

How to Identify a Quality Oil of Oregano

When selecting an Oil of Oregano for wellness use, check for the following:

Botanical Identity

Look for Origanum vulgare or Origanum vulgare hirtum, which ensures you're getting true Mediterranean oregano—not a blend of other herbs.

Carvacrol Content

Quality products list the percentage of carvacrol on the label. Look for levels of at least 60 percent. Higher concentrations suggest a more potent extract, but be wary of synthetic boosting.

Carrier Oil

Only ingest diluted oregano oil. Common carriers include organic MCT oil or extra-virgin olive oil. Avoid products that are not clearly labeled for internal use.

GC/MS Testing

A reputable product should be third-party tested to confirm purity and chemical composition. GC/MS testing ensures you're getting oregano oil free from harmful additives or contaminants.

Packaging

Oregano oil is light-sensitive and should be stored in dark glass bottles to preserve stability and potency.

How I Use It

In my own herbal practice, I rotate Oil of Oregano in short bursts throughout the year. Some of my preferred methods include:

  • Placing 1 to 3 drops under the tongue or in a small amount of water

  • Adding a drop to herbal teas or mocktails for an added punch

  • Combining with honey or olive oil as part of a digestive ritual

  • Pairing with bitters and warming herbs for seasonal immune support

This oil is spicy, aromatic, and bold—exactly what I expect from a concentrated plant ally.
