Q: Hi Dave,
I was just wondering, if some chiles make the skin blister, and pure capsaicin burns through the skin, what does it do to the inside of you?
A: Hello Rob:
Pure capsaicin would kill you if you ate it. The blistering from some chiles involves people with sensitive skins or allergies, and the blistering is contact dermatitis. Studies with video endoscopy show that the lining of the stomach is not affected by the capsaicin in chiles; however, no tests have been done with super-hot sauces, to my knowledge.–Dave
