Here's mud in your eye

I read the latest comment on this phrase, and it was attached to a racing term about the winning horse flinging mud in the eyes of its followers.
I believe the actual origin of this phrase is Biblical, when Jesus spat in the dirt and rubbed the wet dirt (mud) into they eye of a blind man, which healed the man's sight.
I think the phrase is meant to say "here's to cure what ails you".
