Is it safe for someone who doesn't react to poison ivy to eat the berries? I am not going to try it without authority from someone who knows. Is it like smoke from burning vines, that can affect even an immune person?

The word "should" seems wrong. How about "is it safe to..." –  LBell Apr 23 '12 at 14:30
    
I noticed the -1, I'm not sure this is a bad question, even though it sounds crazy. It fits the format, it's pertinent towards the outdoors, and even though it seems obvious to some of us, clearly it is not obvious to all. So... why the -1? –  Russell Steen Apr 24 '12 at 14:47
    
I hesitate to +1 it, because the question is flawed (the "immune" aspect is what bothers me). Otherwise, I agree that it is a fine (though somewhat crazy) question. –  Greg.Ley Apr 24 '12 at 19:54

Your body just doesn't have a reaction on skin contact right now. However most people will develop a reaction after enough repeated exposure. While poison ivy doesn't bother me either, I do take basic precautions to not push my luck. With regular contact, you will develop an allergy, and though it could take years, it will take a lot less if you start eating the stuff.

The part of poison ivy that gets you is Urushiol. It's absorbed readily by the mucous membranes of the throat. If you eat the berries and develop a reaction you are potentially developing a reaction all throughout your throat, etc. If this happens, your throat will likely swell shut and... being miles from medical care... you'll die.

I doubt there has been any scientific study on how many times someone has to eat berries before they develop a fatal reaction (it'd be highly unethical).

Thanks for the reply. I guess I'd better not. –  J. Musser Apr 23 '12 at 1:07

@jmusser -- Yeah, this falls under the list of things I wouldn't even do if I was stranded and starving. –  Russell Steen Apr 23 '12 at 13:24

I actually ate poison ivy berries when i was a kid and i had no idea what they were, and nothing happened to me, but i am immune to poison ivy and i don't know if that was a reaction to me eating the berries. They didn't taste good anyways they tasted like they would be poisonous, super tart and green tasting left my mouth feeling like cotton, i remember my brother flipped out on me, but i just spit out what i didn't swallow and that was it, nothing happened except i had to wash out my mouth a bunch to get the taste out.

well for all of your information, you can eat the berries! it is actually and old south louisiana indian cure for the allergic reaction. you pick the berries when ripened and allow them to get cold, nowadays just put them in your freezer for three days. allow them to thaw and then you eat four to five berries. i used to catch poison ivy if i was anywhere near it and my uncle told me about this. it came from his grandfather, an old cajun indian. i suppose it acts similar to a vaccination. the cold kills any potential poison that could harm you. i have tried this for several friends over the years and it even promotes healing when you eat them if you are currently broken out.

I still don't think I would. But I know Birds do. I have read that there is no irritant in them though so it does make some sense. Just fyi Cold won't kill poison. Welcome to The Great Outdoors S.E. –  MaskedPlant Oct 9 '12 at 20:04

@Jeremy -- There are several issues here from a biology standpoint. Vaccines are for bacteria and viruses. The reaction from Urushiol is nothing at all like an infection. This could not act at all "similar to a vaccination". Allergic reactions are a different response that not solved/fought/cured with antibodies. Unlike an infection, repeated exposure makes you less resistant, not more. Berries can contain less, or sometimes no Urushiol, which basically means your friends just got lucky. Any "healing" you observed was just placebo effect. –  Russell Steen Oct 9 '12 at 23:10

@Jeremy -- Just to be clear though, thanks for joining the site! I look forward to hearing more from you, I just disagree with this particular answer ;) –  Russell Steen Oct 9 '12 at 23:14

Intentional ingestion of poison ivy berries is ludicrous. Knowing what you already know - why even dare to go there? If you are looking for attention getting or want free kicks to get off on you'd be better off playing in traffic. At least in that instance you would have a running head start to get yourself away from the danger. My advice is do not eat or ingest the berries. Worst case scenario is your heart and all other vital organs swell up and/or blister internally! Come to think of it poison ivy looks great from inside a cemetary plot.

Yes, they may be fatal! Is that a risk you're willing to take? As pointed out already even if you eat them once and you're ok, that may not be the case the next time.

If you're unsure of eating anything in particular in the wild I'd stay well away. With something that's known to be poisonous to a large number of people, it just seems silly to even try!

-1 for "you're never find out for sure unless you eat them." Although tongue-in-cheek, this seems to suggest (dare?) a dangerous practice. Additionally, there are lots of ways to find out for sure without first-hand experience: ask the experts being one... –  LBell Apr 28 '12 at 15:38

@LBell It's a fair point, gone now. In terms of "you're never sure", I was referring to the fact that as an individual some poisonous plants / berries can affect you more than others, and (ok, medical tests aside) there's not really a quick way how they'll affect you as an individual. Admittedly not the clearest explanation around, sorry! –  berry120 Apr 28 '12 at 16:09
