Research suggests that European oregano has powerful antiseptic and antimicrobial properties.
European oregano (Origanum vulgare), a Mediterranean culinary herb, is the source of oil of oregano. This hardy perennial herb prefers full sun and well-drained soil.
Oregano, a low-maintenance plant, is generally not bothered by pests. To obtain the oil, the above-ground parts of the plant are steam distilled.
Features
Oregano grows up to 2 feet tall and spreads up to 18 inches. During summer, it produces small white or lavender flowers. According to University of Illinois Extension, oregano plants propagated from cuttings or division have the best flavor.
Geography
Native to the Mediterranean region, oregano grows in the hot, dry climates of Asia, Europe and North Africa. It thrives in U.S. Department of Agriculture Hardiness Zones 4 through 9.
Benefits
Research at Kansas State University suggests that oil of oregano has topical antiseptic and antimicrobial properties. The researchers found that oregano oil is as effective as tea tree oil and more effective than chlorine bleach. Traditional herbalists have used the oil as a remedy for respiratory ailments, but the effectiveness of that use has not been scientifically proven.
