Have you ever heard of 666 Cold Preparation

I was watching this Robert Johnson video:

when at the :51 mark I saw a sign that read “666 Colds Fever”. Thinking it was some sort of devil/crossroads reference, I googled it. Come to find out it is actually a cold remedy. It appears they have re-formulated it but it’s still being sold under that name.

Really, 666? who thought that was a good idea? I’m 64 this month - never heard of it. You?

I remember seeing it when I was in college. A friend of mine got a bottle to use as decoration. As far as I know the medicine is still in there.
