Have you ever had a chicken wing so hot that it put you in tears? I have. But my it turns out that sometimes the crying isn’t just melodrama. Apparently there is a pepper that is so hot that it can actually rip parts of your throat.
The ghost pepper is the world’s hottest pepper. It is so hot that if the wrong amount is eaten in too little time, it can kill you. It’s a pepper that is intense upon first eating it, but slowly causes more pain with time.
Within the Ghost pepper is a high amount of what is called capsaicin. This substance does not react well with the body causes mucus glands to react quickly and intensely. This is why some spicy food help with a runny nose. The reason there is pain is because the brain can not differentiate well between heat (as in actual temperature) and then effects of capsaicin. So essentially your brain thinks that your mouth is on fire when really it’s just the capsaicin reacting with pain receptors. source
One case was so bad that a man ended up with a torn esophagus. In conclusion, it would be wise to avoid this pepper or at least have it in moderation. source
