I don't think they can hurt you. I mean, if it was "hurting" you it would probably "hurt". Does that make any sense?
You should go try all the new Tabascos out there. Garlic, Chipotle....mmmmmmmmm
According to my RD, nope - not going to hurt you! I've had a thing for hot salsa, and I eat it on veggie, mashed potatoes... anything. capsaicin in the peppers can actually sooth the stomach for some people, and help with healing.
