For example...I'm puking, so my mom would buy Sprite, open it up, and let it flatten out (lose carbonation), and then give us saltines. Seemed to work every time. Diarrhea?

If she couldn't pull it out, she'd put clove oil on it until she could get us to a dentist.
What were some of your family's "recipes" to help heal you as a child?
