What fragrance cream do doctors use under the nose during autopsy?

Y-Cream... hence the Y--meaning the Y incision made during autopsy.... might be the slang term... however.... that is what it is called....

It's Vics VapoRub. A dab of it is placed on the upper lip just under the nose to block out any foul smells. But most medical examiners who do autopsies are used to all the smells and are not bothered too much by them.
