Oregano essential oil is distilled from the dried, flowering herb of several different European species: Origanum maru, Origanum smyrnaeceum, Origanum vulgare, Thymus capitus. Most often, the essential oil is distilled from the Hungarian variety Origanum vulgare which is the species commonly found in culinary gardens. Its dominant molecule carvacrol (a monoterpene phenol) is what gives oregano essential oil many of its potent properties. Carvacrol is what also gives oregano it irritating to the skin and mucous membranes, so care must be taken when using it topically.
