1) Antibacterial properties
Oregano oil contains an essential compound called carvacrol, which has antimicrobial properties.
The herb has shown antimicrobial activity in a number of studies. One group of researchers found that Origanum vulgare essential oils were effective against 41 strains of the food pathogen Listeria monocytogenes.
Another team from India and the United Kingdom (U.K.) reported that the essential oil of Himalayan oregano has strong antibacterial properties that may protect against the hospital superbug, MRSA.
“We have done a few preliminary tests and have found that the essential oil from the oregano kills MRSA at a dilution 1 to 1,000. The tests show that the oil kills MRSA both as a liquid and as a vapor and its antimicrobial activity is not diminished by heating in boiling water.”

The project won an award from the United Nations in 2008.
2) Anti-inflammatory properties
Scientists from Germany and Switzerland identified an active ingredient in oregano, known as beta-caryophyllin (E-BCP), which may help treat disorders such as osteoporosis and arteriosclerosis. E-BCP is a dietary cannabinoid.
3) Protecting against cancer
Research published in the journal PLoS ONE in 2013 suggested that oregano exhibits anticancer activity. The scientists concluded that Origanum majorana could help prevent and treat breast cancer by slowing or preventing its progression.
In 2014, food scientists discovered that the popular culinary herbs oregano, rosemary, and marjoram contain compounds that may have the potential to manage type 2 diabetes in a similar way to some currently prescribed drugs.
