Oregano at a Glance
Origanum vulgare is an aromatic perennial in the Lamiaceae family. It is widely used as a culinary herb and has a long place in Mediterranean folk traditions.
Culinary Use
Fresh and dried leaves flavor sauces, roasted foods, vegetables, meats and spice blends. Culinary oregano is a much milder exposure than concentrated essential oil.
Traditional Use
Oregano has been used traditionally for digestive and respiratory comfort and in household preparations. These traditions do not prove treatment of bacterial, fungal or viral infections.
Research
Carvacrol, thymol and other compounds show antimicrobial activity in laboratory studies. Laboratory activity does not mean oregano oil can replace antibiotics or other medical treatment in people.
Essential-Oil Safety
Oregano essential oil is highly concentrated and can irritate skin and mucous membranes. Undiluted topical use can burn, and casual internal use is not equivalent to eating oregano in food.
Safety
Culinary use is generally safe. Allergy is possible in people sensitive to Lamiaceae plants. Pregnancy and breastfeeding concerns are low for food amounts but concentrated medicinal products should be approached more cautiously.
Folklore
Oregano has been associated with joy, protection and household blessing in Mediterranean folk traditions.
Bottom Line
Oregano is first a culinary herb. Its essential oil and laboratory antimicrobial findings should not be confused with the safety or effects of normal food use. For educational purposes only.
