The other two antioxidants are thymol and rosmarinic acid.

According to a study, out of 39 commonly used herbs, oregano had the highest concentration of antioxidants.

Carvacrol and thymol are both found in oregano, which are natural antifungals.

Yeast overgrowth is also connected to ear infections and skin and gut issues.

Oregano oil is both an antifungal and antibiotic that can also help eliminate microorganisms responsible for skin and ear infections.

On the other hand, oregano essential oil can also help with ringworm due to its antifungal properties.

Helps Prevent Cancer

Oregano oil can also help prevent cancer!

How, you ask?

Well, we've mentioned that oregano oil has antioxidants that help prevent free radicals that increase cancer risk.

A test tube study showed that carvacrol helped inhibit cell growth and raised cancer cell death.

Improve Gut Health

This happens when the intestinal lining of the dog's guts is damaged and lets foreign substances, such as bacteria, viruses, and other microbes, leak into its bloodstream.

When these invaders stay over time, they can cause allergies, inflammation, and even chronic diseases.

Oil of oregano can also help your dog improve his gut health.
