Oregano is a warm and aromatic yet slightly bitter herb in the mint family. Good quality oregano has a pungency that numbs the tongue. The best quality oregano is grown in a warm, dry climate. The name is derived from the Greek, meaning “mountain of joy”. Sunlight encourages the concentration of the essential oils that give oregano its flavor. Two other herbs are used in the same ways as common oregano but have different culinary and medicinal properties. Mexican oregano is a plant in the verbena family that has an even stronger flavor, while marjoram is a closely related plant that lacks oregano’s essential oil and has a different, gentler “mouth feel.” The herb is used to treat respiratory tract disorders, gastrointestinal (GI) disorders, menstrual cramps, and urinary tract disorders. The herb is also applied topically to help treat a number of skin conditions, such as acne and dandruff.
