Life / Polish folk remedy for styes? [12]

To get rid of a stye on the eye, my grandmother used to wave a butcher knife in front of us and chant something - I seem to remember that it was three words. Has anyone out there ever heard of this, and if so, what the chant was?

...Also: Grandma had a funny saying she used when she bought something that was more trouble than it was worth. The English translation was, "The old woman never had any trouble until she bought herself a pig." I always thought it sounded better in Polish, but I can't remember it!

Many thanks...
