Butter on a bruise: Latinos have quick fixes for everything. And for some strange reason we feel that putting butter on a bruise will help the swelling go down. To our knowledge, there's no scientific explanation out there to validate whether this works or not, but to us it seems like it does, and we'll swear by it, por mi madre! As the human guinea pig that I was to my parents, they did this every time I suffered a minor accident (which was often). The last thing I needed when I bumped my head was a whole jar of Parkay on my forehead! Gee, thanks mom!
