Can You Eat Poison Ivy?

 A tiny red leaf. It catches the early spring sunlight like a ruby. I hesitate, take a deep breath. Should I eat it? Just a little teeny bite of poison ivy.poison ivy red

It’s research, after all. There’s an old, old belief that eating a leaf of poison ivy every day in the spring will make you immune to the itch. It’s undoubtedly true, I read it on the internet! All sorts of websites attribute the custom to Canadian loggers, Spanish conquistadors, or various unspecified Indians.

But many reputable sources agree that it’s possible to attain immunity by eating poison ivy. Euell Gibbons, the famous wild foods guru of the sixties, swore by this method—he recommended starting in spring when the leaves are small, and eating one a day, therefore getting a small and slowly increasing dose of urushiol, the toxic chemical that causes the itch, so that your system can gradually develop an immunity.

I’ve actually met someone who had done this. A young man who assured me that he ate poison ivy every spring. He was still alive, with lips and tongue apparently intact–he swore it didn’t bother him at all, and he never got a rash. And, better yet, he vowed poison ivy leaves were delicious, with a “light, lemony taste.”

The early spring leaf in my fingers is no bigger than a pea. How could such a small amount hurt anyone? But research has shown that a sensitive individual can get a horrendous reaction from 50 micrograms of urushiol—a grain of salt weighs 60 micrograms.

I drop the leaf on the ground. Nope. Just can’t do it. I’m not particularly susceptible to poison ivy, but allergies are tricky things. You can develop them as you age, or grow out of them. A nibble of poison ivy just might sensitize me so that my next poison ivy encounter would be worse than ever. I guess I’m just not a truly dedicated researcher. I’ll just have to enjoy poison ivy this spring from a safe distance.

  1. I have noticed that eating it doesn’t necessarily make me immune to it’s effects on the skin, though. For example, the other day, I was weedeating poison ivy at chest level, and the juice was just flying. A day or so later, my arms started itching, although I hadn’t eaten any for a few days.

    • Thanks for sharing your experiences, this is very interesting. I think that the human immune system is so complex, and so unique to each individual, that it’s really difficult to predict how we’ll react to poison ivy each time. A cure that works perfectly for one person might not work at all for another.

  2. Well, I tried half a leaf last week. I’ve been increasiing the dose and the frequency of it. I’m up to one large leaf per day, sometimes two, now, more or less. When I started, I was working in it and had some patches of affected skin on the ankles and wrists, but not much considering how much juice was flying when I plunged that weedeater into it. (We’re clearing my land, and overgrown with the stuff.)

    It tastes pretty good once you get accustomed to it. The taste is acquired — kind of like with turnip greens, but there’s nothing lemony about it.

    Here’s a plus. I had an appointment to see a dermatologist tomorrow because of what appeared to be a skin cancer. It has disappeared. I called this afternoon and cancelled the appointment.

    Been considering making some poison ivy pickles or poison ivy pepper sauce. Or maybe I should can some P I for use in the winter.

    • How interesting! Thanks so much for sharing your experiences.
