There was a study found in 14 mice that showed that oregano essential oil improved the survival of 14 mice that are infected with Staphylococcus aureus. It found that 43% of the mice given oregano essential oil lived past 30 days. The survival rate was nearly as high as the 50% survival rate for mice that received regular antibiotics.

There was one mouse research study that found oregano essential oil is almost as effective as antibiotics against normal bacteria.

Improving Cholesterol Levels

There have been some studies that have shown that oregano oil can help lower cholesterol levels.

In one study 48 people who had mild cholesterol levels were given diet and lifestyle advice to help lower their cholesterol levels. After 3 months the group that received oregano distillate had lower LDL bad cholesterol levels and higher good cholesterol levels. And this is compared to those who were given diet and lifestyle advice.

Carvacrol, which is the main compound found in oregano oil, has been shown to lower cholesterol levels in mice that were fed a high fat diet for over 10 weeks.  The cholesterol lowering effect of oregano oil is because of compounds such as phenols, thymol and carvacrol.

Improving Gut Health

There have been some research studies that have shown that oregano can improve gut health.  There was an older study that gave 600 mg of Oregano oil to 14 people who had gut symptoms because of a parasite.

After daily treatment for 6 weeks all participants experienced a reduction in parasites and 77% were cured.   They experienced a reduction in gut symptoms and tiredness associated with other symptoms.

There was a study on pigs where oregano essential oil protected the gut wall damage and prevented it from being leaky.  It reduced the number of E coli bacteria in the gut.

Studies shown that oregano essential oil helped relieved pain significantly in older mice. There still needs to be more studies on humans to validate this effect 100%.

Research has shown that oregano oil can reduce inflammation. Carvacrol one of the key components in oregano oil has been shown to reduce inflammation in mice. But more studies in humans need to come out to validate these effects.

The Bottom Line is there are a lot of health benefits to oregano oil, and it is important to have it as a part of your regular diet and lifestyle regimen.
