Baking soda nearly killed an elderly man. He was using it to relieve the stomach pain caused by an ulcer, but went way overboard with the mildly basic home remedy. http://blog.wired.com/wiredscience/2008/01/death-by-baking.html
Baking soda can be used to relieve acid indigestion. Try it sometime for heartburn or upset stomach, it works really well. This poor guy has an ulcer and no health insurance. You shouldn't call him a hick...
People use baking soda all the time for heartburn and stuff. I have tried it a few times when I didn't have rolaids or tums or something. You're not supposed to swallow it however, and this man probably swallowed a whole bunch of it!
