I know several people who have had a very severe allergy to poison ivy/oak/sumac. Myself, I've never had any allergic reaction to it.

There is a service in the area up here where you can rent a few goats that are let loose in your yard to eat all the poison ivy and stuff that you don’t want there.

Sadly, you can become allergic.

The same thing is available here. I worked with them for a few years. Great fun!

From my experience, the favorite foods of the goats, in order, was kudzu, privet and poison ivy. They would head-butt each other for access to any of that.

I read a study on NIH where people's hands were rubbed with a poison ivy leaf. They were told it was a harmless leaf. They did not get a rash. When they were told a harmless leaf was a poison ivy leaf, and they were rubbed with it, they got rashes.

If you tell a person allergic to nuts that a food doesn't contain nuts, is it true they would not have a reaction if they ate something containing nuts, simply because they expected not to have a reaction? (Reactions to poison ivy, despite its name, are allergic, not toxic.)

I heard the brain is very powerful and stuff about mind over matter. I also read about Pavlovian (conditioned) allergic responses. The Japanese poison ivy study showed this effect can work both ways. The poison ivy study was a study on the placbo effect, which is generally accepted as being a legit thing. There's many people who think this could be ESP/psychic phenomena, as no biological mechanism exists for it.

The less you post, the better.

I've heard that before, which is why I avoid getting it on me. Plus if you get it on you, you can transfer it to a loved one who is allergic to it.

I've seen people get some really bad allergic reactions from it. So bad that they have to be prescribed a corticosteroid like prednisone, which can have some bad side effects.

One dude I know got it on his hands, then rubbed his eyes. His eyes swelled shut and he had to go to the ER.

I have been allergic to poison ivy my entire life. I grew up playing in the woods behind my house, so I had it more often than I can count. I don't think there is a place on my body that has not had a rash and blisters from poison ivy.
