When we eat a lot of peppers, the inside of our stomach starts to burn really bad. To ease the pain, we usually drink iced water or cold milk and some people said they eat peanut butter sandwich with the milk. So question is, what happens when you swallow a clove of garlic?

Does the garlic burn your inside really bad? Some people even swallow 2 at a time, can it kill you by just swallowing 1? What's the risk? I remember having chewed and swallowed a garlic clove that really burned me bad afterward.
