Oregano is an antibacterial oil. It is NOT pleasant smelling. Its high carvacrol level seems to make it an effective germ killer, but also gives it an extremely pungent smell and makes it a strong irritant to the skin and the mucous membranes.
WARNING: Oregano essential oil is a very strong skin and mucous membrane irritant. If you plan to use it on the skin, use a VERY mild solution.
