Beware of Burning Poison Ivy or Oak It's getting colder outside and a nice warm fire in the fireplace sounds good. You venture outside and grab some cut firewood and toss it in the fireplace. The only problem is there was a dead poison ivy vine wrapped around it. This could be very dangerous.

It is tempting to burn a poison ivy or oak plant when you want to get rid of it for good, but do not ever burn them! The poison plant oil called urushiol can burn, and you can inhale the toxin. This could cause a very severe allergic reaction.

According to the Wildland Firefighter Magazine website, inhalation of burning poison ivy and oak plants is common among firefighters although much less common among the general population. The heavy particles of the smoke contain urushiol, which will fall down in soot form and can be inhaled. The lungs can swell, cause coughing, and extreme irritation and swelling in the throat. It can also cause blisters that break and run.

Know where your firewood is coming from. If you have freshly chopped firewood that may have been growing near poison ivy or oak, be careful and think twice about burning it. Also if you have broken out in a poison ivy or oak rash after handling firewood, that may be because the plant's oil is on the surface of the wood.

If you think you may have inhaled burning poison ivy or oak, seek medical attention immediately. Only a medical professional can administer proper treatment in such a case.

    Question: We are cutting down a tree that has a thick poison ivy vine going up it. It is winter time, so, the ivy is dormant. Further, we are yanking it off as we cut the tree down. Can we use the wood as firewood in our fireplace at home? Thanks!

    Poison ivy oil, called urushiol, can stay on the surface that the poison ivy plant has come in contact with. I would suggest NOT taking the risk of burning it because if you inhale the urushiol it could result in a very bad allergic reaction.

    I've been burning plants and shrub cuttings from around my yard, I know I have poison oak in the yard and think I am almost killed it all. But now in the last week my legs swelled up to twice there size for four days and now my lungs are burning and I have a cronic cough, sore throat and fitigue. Is this a common reaction?

    Chris - Burning poison oak can cause the rash causing oil, urushiol, to become airborne and result in you inhaling the allergen. This can cause a systemic allergic reaction and you need to consult your physician right away for proper treatment.

    I was hospitalized for two days with poison in my lungs, ears, nose, throat and eyes. It is very dangerous to burn poison ivy or oak. I was told by the doctors at Monongahela Valley Hospital that you could get phenomena from the poison in your lungs. I was on bed rest for three days and I had to take several allergy medicines and a steroid. I was told that the severity of my case could have caused death within 48 hours if I didn't seek treatment. Beware of what you are burning folks!

    How soon after being exposed to smoke containing urushiol would a respiratory reaction occur? I know a skin rash can take several days to fully emerge but would one know sooner if they were going to have internal issues?

    We cannot say for certain if a your tree would be safe to burn. Urushiol can stay on surfaces for years and a very small amount can cause a big reaction. Trees that have poison plant oil on them should not be burned.

    Reactions to urushiol can vary by individual depending on how sensitive they are to the plant’s oil. If you know you have been exposed to burning poison ivy or oak it is best to consult with a medical professional for guidance.

    I burned a brush pile today that was completely covered with poison ivy, It was about 7 hours ago and I had some shortness of breath and my albutarol inhaler made it worse. Should I be concerned at this point or will I be alright if my symptoms have subsided for now?

    I accidentally burned either poison Ivy or sumac probably about 8 years ago and that night my face swelled up like a puffer fish. I now have annual rashes that breakout on my body even though I'm nowhere near the stuff. Mostly in summer time when I sweat.

    Kevin: Yikes! As mentioned in the article, never burn poison oak or ivy plants, inhaling the smoke is very harmful and potentially fatal. It sounds as if you may be experiencing systemic poison ivy rash, we would definitely recommend contacting your physician and discussing your symptoms with them!

    Thanks for all the advice. Just got over poison ivy rash about three months AGO. Didn't realize till I broke out that what I was chopping down was poison ivy n or oak in my back yard. Therefore, at that time I threw it all into a pile with a tree branches and bamboo trees I was chopping all at same time. Pile was intended, of course, to burn. Now three months later, I can't even pull good wood out of pile to burn. Does anyone have any recommendations on how I dispose of the huge brush pile. Can I spray any type of poison ivy killer on it to kill the urishol before burning. Like the stuff the kills the live plant. Also if I remove the large pile (somehow--ideas) Will ground underneath still have urishol remaining? Any advice would be greatly appreciated, being that I live in an Upsale neighborhood and they will not allow the pile to remain long past the "bonfire"season." However I am also tryin to be a responsible neighbor and not burn when it could be a serious detriment to others health if smoke is inhale. Do not want the rash back myself either. After a month, in the hot sweaty summer battling the itchy spreading Case, being I am allergic. Suggustions??? ---P.S. SORRY FOR SUCH A LONG POST,JUST WANTED TO COVER IT ALL!!

    Richard: It is hard to say how soon you may or may not experience symptoms. There are so many factors that could play a role: how much was inhaled, your sensitivity to the plants, how many times you've been exposed to the plants in your lifetime, etc. If you start to experience any discomfort, trouble breathing, or a rash, we recommend contacting your physician right away.

    Lisa Lynn,
    Unfortunately, plant killers will not neutralize the urushiol oil so it will still be unsafe to burn. I suggest you contact a company that specializes in lawn waste removal, as they should know how to dispose of contaminated tree branches. If your local garbage company picks up a yard waste container, you could collect the debris using a large garbage bag turning it inside out to minimize contact and put it in the yard waste container for disposal. Be sure to use protective gear and a dust mask while handling the yard debris.I recommend washing contaminated clothing with Tecnu Original following label directions.

    I cut down a 48" diameter river birch at my father's place that was way past its prime, and there were six poison ivy vines (ranging from 1/2" to 4 1/2") attached to the tree. My father believes that now that he tree has been down for 10 months that it is OK to burn the tree and the ivy. I disagree. Is there any documentation that I can use to reinforce my position? I have gotten a quote from a company to remove the tree and the poison ivy but being a man from the country, Dad thinks I am over doing it.

    Buster: Urushiol, the oily resin from poison oak and ivy plants, does not evaporate and can last for months, even years and still cause a rash (or a more serious condition in the case of burning it). Even if the plant is dead, the urushiol still remains, and burning the plants can be fatal. You are correct in this situation, it is NEVER safe to burn poison oak and ivy.

    This was asked but not answered...we pulled our p.I. and had a landscaper remove the large pile. The pile was over our grass parking pad,does the oil bond or transfer to the ground or is it likely safe to walk on in . Flip flops?

    Amy, urushiol (rash-causing oil from poison oak and ivy) is a resin that does not evaporate. It can transfer to any item it comes into contact with, even grass. It wouldn't be a bad idea to wear shoes when walking through that area. Be sure to leave the shoes outside to avoid tracking urushiol into your house.

    Chris, we have never tried or tested it, so if we said yes or no, it would be a guess. Urushiol is a sticky sappy oil, so a little rain probably wouldn't do much to remove it. Better safe than sorry.

    I am very allergic to poison ivy. It was burned by someone in the neighborhood near my dorms and some hours later I went outside. The next day my skin broke out in a rash. There is so much or it on my legs that they look sunburned my knuckles look like I punched a wall. My arms have a classic looking poison ivy rash. It is also on my neck and face. I didn't inhale anything thank goodness but I only got it a little better because let me tell you head to toe poison ivy is not fun.

    Where I live there is a lot of land clearing being done, this also means a lot of burning of these piles of brush. I can guarantee that many of these piles contain poison ivy as it is pretty heavy here. Was wondering if this is an issue for those people that drive past the burning piles along the highway. Does anyone know what the safe distance is before the burning urishiol drops to the ground.

    Jim, urushiol (rash-causing oil from poison oak and ivy) does not evaporate. Even when the vines of the plant have died, the urushiol is still active and it is never recommended to burn them.

    Si: As far as we know, symptoms from smoke inhalation can present as soon as a couple of hours after inhalation, up to 48 hours later. If you think you may have inhaled smoke from burning poison oak or ivy, whether symptoms are presenting or not, we recommend seeking medical attention immediately for proper care and treatment.
