Relief, it says

For the relief of bland foods.  The word "Aspirin"  is derived from acetyl and spirsäure. I always think of a part of one of my favorite movies "The Birdcage" where the house boy gives the diva "pirin" tablets. He scratches off the "as" to make the diva think the pills are something more potent. Of course I am also reminded of (when as children) we would draw out the word....assburn.
