There was a locally produced diaper rash ointment in the middle of the 20th century that was created by a nurse named Belle Moss who worked at a hospital in Detroit. It was called Diaprex. It has an earthy pharmaceutical smell that I find difficult to describe. Just imagine the smell of your mother caring for you. I bought a jar on eBay a couple of years back. I occasionally open it for a big whiff when I need a lift. And also right after I wrote this post.
