I do have a story about this. All my life I've loved hot peppers. Not necessarily the hotter the better, I still like to taste them. But one time we had probably 100 plants of hot peppers, and an early freeze was predicted. I picked all of them and got them ready to freeze. I did have those plastic gloves on. About 3 hours later we were sitting at a restaurant and I started shaking all over, and I was just burning up inside. It gradually went away, but it was obviously a toxic reaction to the peppers.
And yes, I know hot peppers prevent ulcers. I am 62, and my brother now is 80. He has had ulcers since he was in his 40s, and each '10' year birthday he tells me, now you're 40, you're going to get ulcers, now you're 50 you're going to get ulcers, now you're 60...Well, no ulcers yet, and I told him it was due to all the hot peppers and spicy foods I ate. We looked up info about it, and that is the case. If you already have ulcers it would give them a 'time', but if you don't it's a great way to prevent them, and get your overall pain levels down too.
Great article as always!
