I found what I thought was Poison Ivy in my yard. I then searched KZfaq for videos identifying the plant. Yours is by far the best one. Thank you.

Something this video fails to explain is that urushiol should be treated like a poisonous invisible grease; something analogous to an automotive grease that you can't see. Using only soapy water and rubbing contaminated skin with your hands won't effectively wash it off. A washrag or something equivalent is needed to effectively remove urushiol residue from the skin.

I've watched a lot of videos about poison ivy-oak-sumac, and I have to say this is the best and most informative one I've seen. I live on 10 acres in the woods and it is literally everywhere. Thankfully I don't get affected by it, but my wife on the other hand is one of the most sensitive people I know. I like how you covered boxelder too. I just found a boxelder tree in my woods behind my pole barn and was confused until I researched a bit and found out what it was. Great video sir!

By far the best informational video on poison ivy I’ve ever seen! You actually got into the botany science explaining the difference in the leaf structures! I learned a great deal here, even beyond the primary subject matter. Makes me want to study more about plants in general. Thank you!

The best video on poison ivy and other poisonous plants I have yet to see anywhere. Thanks.

Botany lesson on leaves starting at 4:00 was A+. After watching this, I was finally able to identify poison ivy without freaking out about other plants that have a leaf with compound leaflets and a singleton at the tip. Thanks!

This video should be presented all through 3rd grade through high school. Yeah, many people need to hear & see it more than a dozen times.

Very good video,thank you...now I know. I'm cleaning out old fence line so I'll be very careful not to touch the plant or the vines... You are a very good teacher.

Best Poison Ivy video I seen. Thank you. When I was a young boy. I loved to explore the woods. That's when I learned the hard way. Poison ivy grows in vines. I had it all over my face and my arms.

Also use dawn dish soap. If the rash breaks out use zanfel. It's expensive but works miracle well!

Washing with only cold water is going to do nothing! Use any kind of *soap WITH A WASHRAG* to both break down the oil AND mechanically remove it. Just try washing any other kind of oil -- butter, olive oil, bacon fat, packing grease -- with cold water alone. Then wipe vigorously with a cloth or paper towel to see the difference. Definitely appreciate the botany lessons for telling them apart, especially difference between the toxic plants and boxelder!

This was the best info that I have ever seen , great job!

Simple yet Brilliant and informative.

Thank you for the detailed education on leaf types and how to distinguish what is or is not poison ivy. I found this very informative and useful. Thank you!

This video is 8 years old, but I just wanted to say that from personal experience, I have seen poison oak, ivy and sumac in Northern California. Specifically in the Sierra Nevada foothills in the general area and surrounding areas from the valley of Sacramento up to the higher elevations in Nevada County and also a little lower in Yuba county. I was not allergic to these plants when I was younger and lived in Arkansas. When I was 13 I got mono and ebstien bar. Not sure if it is only a coincidence but I have been allergic to this oil ever since. Have had so many severe reactions after hikes in the woods. I thought poison oak was all I had to look out for but after getting a severe reaction seemingly different slightly than before, I went back to see why and I found ivy and sumac poison plants scattered everywhere as young and small plants sprouting up. It was early spring and the ivy was starting up everywhere and the sumac was coming up in the area’s with soft and waterlogged earth. This was several years ago and I have noticed all three plants nearly every nature walk through the woods since then. They have definitely had no problems flourishing here and have been the cause of many weeks of misery for me.

This has got the be the best video I've seen on identification. Thanks!

Watched the whole thing. Now I can’t stop the itching!

Leaflets aren't always attached to rachis -- sometimes they're on windshield wipers.

Great info, i'am suffering right now with this rash.My dog ran through the woods 2 Sundays ago. I know thats how I got it. I had really never known what these plants look like. Thanks...............

On those big poison ivy vines climbing the trees do the following to kill it down to the roots. Make a small cut about 1/2 way through about chest height. Spray full strength Crossbow herbicide in the cut area. You can use a brush also to apply the herbicide. Go back every few days and repeat. You can use a brush too to apply. After a week or two, finish cutting and hit the stump with another application of Crossbow. If you just cut the vine all the way through the ivy will start sprouting from the roots all over the ground. Do this and it will kill it roots and all. Incidently, Roundup will not work nearly as well. Its just not that good on viney plants such as Ivy and honeysuckle. Applying Crossbow or Roundup directly on the stump of a tree within a few minutes of cutting will prevent it from sprouting back up. Trees like maple and sweet gum, which is a type of maple, are good candidates for doing this.

Educational. I'm not familiar with it but now I learned a lot. Very informative. Thank you. Godbless

I live in North California and now I know what that pretty dark green vine in my flower garden is. Thanks so much.

What a great educational.video!!! I am one of those that suffer greatly every time I have an exposure to poison ivy. This video is worth watching multiple times!!! Thank you!!!

I've also gotten it in winter from the stems.

It's also very good advice to use a cloth to give the infected area a good wiping with a washcloth with soap and water

I wish you had gone into detail of how to identify poison sumac... There is much of this sumac on long island ny.. Perhaps u can address poison sumac on another video.. All that said i would like to thank you for your expertise and efforts...God Bless

Really great video! Learned so much and thanks a lot for sharing!

Definitive poison plant identifier tutorial. Thank you.

Very informative. Thank you! I have always been allergic to poison ivy and, having woods on my property & several creek banks, I'm always on the look out for it.

70yr old man - born in the coal fields of SE KY. I was taught .... LEAVES OF 3 - LET IT BE.

Thank you, Thank you, thank you. After my first recent exposure to poison ivy, I did not want to come to my garden. Your explanations and video guide help a lot.

Sir, excellent video. Thank you for this gift to us and for your time.

This guy is almost as passionate about Oklahoma as he is about poison ivy!

I’ve been looking for good poison ivy identification videos and pictures for years. This is the best id video I’ve found so far!

The Sherrif says "kill it before it grows"

Its good to be familiar with identifying poison ivy without leaves before you start running a chainsaw. Trust me on that. I didnt realize that 3" thick vine wrapped around the dead blowdown was poison ivy. I found out a few hours later though.

Great video. I like how you showed that poison oak can be mistaken for poison ivy. Knowing that, I think I may have some poison oak out front instead of p ivy

Very impressed with this informative & educational video! Thank you for sharing your knowledge!

I started collecting small trees in my back yard to make into bonsai and ran across a sapling with an interesting leaf shape. I am glad i saw this video and could tell difference between boxelder and poisen ivy. Thank you. I will very carefully pull them out and garbage them

Best video I've seen about poison ivy. Thanks

I wish i could find an in depth video like this on poison sumac (ohio)

Thank you for your video. It is the best one I have seen on identifying poisonous plants..esp poison ivy.

Wow! Fantastic video...I will never have a question again about poison ivy and its relatives.

Keep a full tube of Zanfel if anyone is allergic. Use Zanfel soon as possible one time at first sign of breakout is much cheaper than after it spreads.

Great video. Straight to the point. Easy to understand. Very helpful. I am new to Texas, never saw or heard about poison oak or ivy. Love camping. Need to learn.

This is making me itch... Proper pronunciation of pecan earned you a subscriber.

Good old KZfaq when udecative content was made with poor quality cameras and yet it is still interesting. Now it's all about clickbaits.

In California there are poison oak and poison sumac only.

Thank goodness here in Puerto Rico there are no poison ivy nor Ryberg's poison ivy nor poison oak nor poison sumac in its forests.

Thanks for these valuable info. I had doubts whether my hives emanated from the garden or the food alergy, but now i am almost certain that I have had this poison ivy. But I am told there is no poison ivy in UK.

The coverage area maps brought back some nostalgia. Used to be that N of the NH white mountains there wasn't any. But temps have warmed up enough that poison ivy is now well well N of the ranges on the 9:04 map.

The Willamette Valley in western Oregon has a large number of poison oak.

To add ... Urushiol gets into the trees poison ivy/oak attaches itself to . Avoid any logs that had vines attached to them, and especially ones with reddish-purplish streaks in them !!!

I live in Tulsa. I found what I believed was poison oak growing from the ground as if coming up from an underground vine. This was after searching due to getting a short-lived rash after doing some trimming in my back yard. I cut the plants at the ground, bagged them and sprayed Roundup. I kept this up all summer in several sections of my yard inside and outside a chain link fence. My yard is heavily shaded and overgrown with a variety of vines and small trees. I found the major vine( 'hairy' and about an inch in diameter) on the fence. I cut it at the base and sprayed it with roundup. This was 5-7 years ago. I have not come in contact again with this plant nor seen any plants. I have plenty of Virginia Creeper and sometime have to take a double take, but so far I feel it is long gone. Could I be so lucky as to have killed it off, or should I expect to see it eventually reappear. THanks. Your program was by far the most helpful and informative! I never wear gloves when pulling vines. I recognize most tree seedlings. I just trust my eyes and love to be outdoors pruning and pulling greens that don't belong. Could I be immune? Or just lucky. Thanks.

This video is very useful I appreciate this opportunity for you to teach us to be careful in the forest or at our backyard or anything outside to be careful not to touch any plants. P.s ❤️

Poison ivy, poison oak, poison sumac. I’ve had them all. I’m starting to itch just listening to this!

This was awesome--really well explained. And cool jazz at the end :)

Are pets like cats and/or dogs allergic to poison ivy, etc.

Very informative!!! Great explanation. Thanks so much for educating.

Use wash cloth and soap. Friction is what removes it from the surface.

Best information I have ever seen on poison ivy.

Young ash trees are often confused as well.

the best video i come cross on this matter so far, well explained with abundance of info . thank you for sharing your knowledge

This guy sorta reminds me of a young Martin Milner from the Adam-12 tv series. Officer Pete Malloy reporting for a discussion about the dangers of poison ivy! I learned a lot! Thanks!

Thanks for making this video, it was very educational for me. I just wish I had seen it a week ago. LOL! I got into some poison ivy last week and have been trying to get rid of the rash ever since.

Your choice of thumbnail is unfortunate, as it seems to identify a tree's compound leaf as poison ivy.

When he showed the "good" sumac, he picked up the vase first with gloves on, then afterward with them off. If they were the same gloves with which he handled the toxicodendrons, then he wound up getting urushiol on his hands.

Was that even poison ivy during the botany lesson? I don't think it has serrated or crenated leaf edges. I have seen it present as a "mitten" but mostly it is smooth-edged.

Poison oak in California certainly climbs as a vine. It’s nasty along the coastal region.

Like he said, there are variations in the sub species. Other plants can break you out. Poison hemlock, cow weed, hogweed, & this red vining plant with feelers like grapes that has compound leaflets of three. Grows from Florida to Virginia & is in the wisteria family.

The BIG question is ...DID YOU GET POISON IVY from making this video !!!

The picture shown before the video begins, looks like poison Sumac.

Excellent annunciation Clear @ 2 X speed

Thank you for making this excellent video!

A caution worth adding is the affect of poison ivy if you are particularly sensitive to it or, in other words are "hypersensitive" to urushiol . In this case, pistachios and cashews are NOT made edible by roasting and the ooze from blisters will spread a reaction. I would also recommend against handling a mango if you are hypersensitive.

Excellent presentation that is packed with factual information.

I found a vine growing up a tree in my yard and I was not sure if it was poison ivy. It turned out it was Virginia creeper

Cold water causes an increase in oil not flowing (staying on your hand). That is called viscosity, resistance to flow. Interesting about the cold water. They want your pores closed, and that makes sense too.

The best thing I have found for washing off urushiol oil is a product called Tecnu. It has mineral spirits that cut through the oil.

One thing I've been noticing about poison ivy is that it grows where man goes. Basically any area devoloped by man...such as golf courses, farms, and even along well used woodland paths. I can't recall in 62 years ever finding it deep in untouched woods. Funny thing...I walked through the woods many times over the course of 40 plus years...finally got poison ivy rash on both arms and shins chasing after a 50 cent golfball. LOL

Nice video, Fels-Naptha Soap is suppose to have something in it that will stop the itch.

I live in Missouri, the middle bottom of the state, about 50 miles east of Branson...I have poison ivy and oak if anybody needs some..

I was always taught," leaves of three let it be" when it comes to ivy/oak when cutting weeds, or camping, in woods, etc,.. So it has kept me safe from it.

Excellent presentation!

Thanks... very informative. However, I now itch all over! Just the thought!

Plenty of poison oak in costal Southern California.

Scrubbing with ultra dawn dish soap then with straight white vinegar. Then dishsoap again works incredibly well.

Once you get the rash, apply Hydrogen Peroxide directly to the rash areas and it will help the substance dry out from the inside without causing more inflammation to the skin area. Simply with your finger, dipping it in the hydrogen peroxide bottle, or spray directly on the rash. Simply put you don't end up with the flaky areas when it's healing and hydrogen peroxide becomes your friend.

Dude everything looks like poison ivy or oak to me. Screw hiking I’m staying in doors

Please also make sure when you wash yourself from poison ivy to also use Dawn dish detergent. You need something that will cut the oil, not just water.

Can you prove that urushiol isn't coated on the outside of the leaves?

Your maps show the state of Oregon to be free of these toxic plants. However I grew up in the Willamette Valley and we have a type of Poison Oak which is quite prevalent. Its foliage becomes quite shiny and red, and dwells in shady areas under conifers. It’s a ground creeper. Can you say something about this one?

Had some young campers go off on there and cook hotdogs and marshmallows on poison ivy branches. They passed away.

I used to be able to roll around in poison ivy as a kid. Now I break out. Kind of sad. I liked being immune to it as I spent a lot of time in the woods.

You can use hot soapy water and friction, eg a rough wash cloth or sponge to wash the oil off the skin up to a few hours after exposure. Any time I have been exposed( its in my yard!) it takes several days for a rash to appear or any itching.

Thank you! Excellent information and presentation.

As far as I know, you absolutely can and should wash and scrub your skin with dish soap and a washcloth as soon as possible after exposure. There also exist products that do basically the same thing for a huge markup. I don't understand why this video says you wouldn't be able to wash urushiol off your skin, that just doesn't make any sense.

Thanks ... so helpful

You can’t wash it off with water alone! Must use a serious degreaser and an abrasive rag or green scrubbie thing. Soap and water with no scrubbing won’t remove it either!

In medical terms, the armpit is known as the axillary region.
