Jalapenos do that, Haberneros don't. But if you make your own, you must dilute the Habernero, unless you're a masochist.
Don't get the juice in your eyes or under your fingernails.
I thought so too but my mouth got used to the Habenero. Now I just sweat like a pig.
And if you are male, wash hands carefully before going to pee.

WRONG!! Once, on a bet, I scarfed down 3 fresh, raw, habeneros. I won the bet, but within an hour I felt like a rabid bobcat was trying to claw it's way out of my stomach. I had to leave work and go home. Did I take a couple of months of grief was that? Yes, I did. But, of course, my misery wasn't over, as the stuff worked its way through me. The climax was quite agonizing. A word of advice. Don't try this. But if you do, have something in your stomach first. It might help.
