Oregano, a member of the mint family, is a culinary herb used for the flavor of its leaves.
Oregano oil is high in phenols, which are natural phytochemical compounds with beneficial antioxidant effects. The two most abundant phenols in oregano oil include thymol and carvacrol. Thymol is a natural fungicide with antiseptic properties that helps boost your immune system and works to protect against infections and seasonal illness. Carvacrol is effective against various bacterial infections, and has also shown promise in preventing food-borne illnesses caused by pathogens. Other healthful compounds in oregano oil include terpenes, which have powerful antibacterial properties.
