Ointments, balms, salves

The humorousness or these similar topical applications amuses me. Makes me wonder what standards or benchmarks must be met to be considered as such.

I have ointment and one balm in my abode...clear difference. Clearly, the balm has a much more naturally pungent smell to it, while ointment tends to be scented?

I wonder if there's some governmental oversight here, or anyone could manufacture an creamy-type substance and call it a balm just to be a balm...hmmmm.
