Although oregano contains the vitamins and nutrients required by the immune system, its primary benefits are owed to its carvacrol and rosmarinic acid content. Both compounds are natural decongestants and histamine reducers that have direct, positive benefits on the respiratory tract and nasal passage airflow. Oil of oregano fights off the dangerous bacteria Staphylococcus aureus, better than the most common antibiotic treatments. Oregano has so many health benefits that a bottle of organic oregano oil should be in everyone's medicine cabinet.
