Odd ads 1947: To much truth in advertising?

I love words and when I see one that is rarely used, especially to name a product, I want to jump on it. Except with this one, I would slide right off. 

Not the best way to sell a product, with a name that's is difficult to pronounce. Unguent comes from the Latin - "Unguen" - to anoint, and there is the root. So, if this were really a truth in advertising would we change the product name to "Anoint-ment?" I'd need a pretty painful itch to use it.
