Note: This article focuses on treatment of external poison ivy, oak, and sumac.

Before moving to Western North Carolina poison ivy was seldom an issue for me.

Since moving here seven months ago, it has claimed me as a victim twice – it’s all over here! That’s good for you because it has allowed me plenty of trial and error to discover a treatment that works.

The best treatment is to avoid exposure, but if you’ve already contracted a rash don’t worry, there is hope.

Before we get to the treatment let’s analyze several myths so we have a full understanding of the topic.

Poison Ivy, Oak, and Sumac Myths and Facts

1. The rash is contagious. MYTH

Fact: The rash is derived from urushiol oil secreted from poison ivy, oak, and sumac. The rash is not contagious but urushiol oil can be spread if not removed by washing.

2. Scratching and popping blisters will spread the rash. MYTH

Fact: The rash is not caused by the fluid in the blisters, it is a reaction to the urushiol oil. As long as the oil is removed it cannot be spread.

3. You’re either allergic or you’re not. MYTH

Fact: Your allergic reaction to poison ivy can develop, increase, and decrease from year-to-year, even if you’ve never had it before.

4. You can catch the rash by standing near the plants. MYTH

Fact: Direct contact with urushiol oil is the only way you can be affected. While you cannot catch poison ivy by simply standing near the plants, there is an exception: if the oil goes airborne which can happen in a fire or if the plants are run over with a lawn mower.

5. Leaves of three, let them be. MYTH

Fact: This is only true for poison ivy. Poison oak can have between three and five leaves while poison sumac has between seven and 13.

Prevention Through Identification

Poison Ivy Treatment

Prevent reactions altogether whenever possible by educating yourself and avoiding exposure.

Look at the above photo and be familiar with poison ivy, oak, and sumac so you can identify and avoid contact. Remember that poison ivy always has three leaves, poison oak has between three and five, and poison sumac between seven and 13.

When in areas of known growth, wear long clothing.

If you do come in contact, using soap and cool water to wash the urushiol oil off your body, clothes, shoes (and any other affected surfaces) as soon after exposure as possible will help you prevent the rash. Using cool water will keep your pores closed and slow your skin’s absorption of the urushiol oil. It’s debatable how soon the oil needs to be washed off to avoid the rash, some say 30 minutes, others say several hours. What is known is that you want to remove the oil as soon as possible.

If you already have the rash, read on and try the solution that worked for me, or one of the other solutions listed below.

Successful Treatment of Poison Ivy

Fels Naptha soap, Everclear ethyl alcohol, and tea tree oil.

Note: Fels Naptha has some unnatural ingredients; see list below. If you’re uncomfortable with this soap, don’t use it. An alternative is Burt’s Bees Poison Ivy Soap and I’ve listed its ingredients further down in this article.

I use Fels Naptha because it’s better at removing the oil, stopping the itch, and drying the rash than anything else I’ve tried. I have studied the ingredients and know they’re not all natural, but since I’m not leaving it on my skin, I’m comfortable using it in this application (use and rinse off immediately) the handful of times I get poison ivy each year. If you feel different please try a natural alternative. Two ingredients (underlined below) are banned for use in cosmetics but are still used in “leave-on” applications like antiperspirant/deodorant. I would NOT recommend using and leaving on skin.

I believe Fels Naptha works so well in this application because it is made to remove oil based stains (like urushiol oil).

Ingredients: soap (sodium tallowate*, sodium cocoate* (or) sodium palmate kernelate*, and sodium palmate*), water, talc, coconut acid*, palm acid*, tallow acid*, PEG-6 methyl ether, glycerin, sorbitol, sodium chloride, pentasodium pentetate and/or tetrasodium etidronate, titatium dioxide, fragrance, Acid Orange (CI 20170), Acid yellow 73 (CI 43350).
*contains one or more of these ingredients

Here’s how to best apply the treatment:

  1. immediately launder any and all clothing that may have come in contact with urushiol oil (our homemade laundry detergent works great)
  2. use Fels Naptha soap and water to remove any urushiol oil from any door knobs, tools, surfaces, etc.
  3. remove any urushiol oil from your body by taking a shower and applying the Fels Naptha to all affected areas and rinsing off
  4. scrub the affected areas with a toothbrush or washcloth to pop the blisters
  5. dry off and apply our antiseptic homemade deodorant to all affected areas (made of 4 oz. Everclear ethyl grain alcohol and 40 drops tea tree essential oil)
  6. reapply antiseptic homemade deodorant once every hour until rash dries up and begins to disappear.

You should see results within a few hours.

Using this treatment dried up my poison ivy overnight!

Other Treatments

While these treatments were less successful for me, they have worked for many others in the past and may work for you.


Many have had success using jewelweed. My experience was that it helped relieve the itch but did nothing to help dry up the blistering rash.

Rhus Toxicodendron

Rhus Toxicodendron is a homeopathic remedy commonly taken in 30C dosages of five pellets. I tried this for three days without success. This works great for many but I recommend consulting your Naturopathic/Homeopathic Doctor so you can administer the best individual dosage for treatment.

Burt’s Bees Poison Ivy Soap

This is an all natural soap that many have success with; I had success using this soap (and applying the homemade deodorant) but the results took three days. If you are concerned about using Fels Naptha, try this instead. It didn’t work near as quick for me, but was still effective so I encourage you to try it.

Ingredients: vegetable soap base, kaolin, avena sativa (oat) kernel protein, melaleuca alternifolia (tea tree) leaf oil, pinus palustris (pine) wood tar, impatiens balsamina (jewelweed) extract.

Trial and Error

Understand that not everyone will have the same experience.

The best solution for you may be different from mine, and different from the next guy. This is normal because we all have different levels of exposure, different skin types, different allergic reactions, etc.

Try the treatment that sounds best to you and see if it works. If not, try something else until you find what works best for you.

    My boughts with Posion Ivy are epic. The worse case I got on my abdomen from a dog brushing against me. I have had it where the sun don’t shine. Technu has helped me greatly but I still usually wind up in the ER at least once a season. For some reason it gets into my system. I am assuming that the medical people mean my blood system and it spreads to ridiuclous places. Something that I have learned since moving to Western NC is that usually you can find jewelweed close to posion ivy.

  2. Sustainable PF says

    Really useful remedies Matt. I am lucky to, it seems, be immune to this stuff which is a good thing. The folk festival I have attended 26 years now, and many of late as an organizer (where we go to the site for work weekends and such) means I am walking through the woods, usually in shorts, and I must get hit by the stuff.

    My wife and son however – likely not as lucky. I’ll note this article for when we need treatment.

  3. Becky says

    Thank you all for all this wonderful information on poisin ivy. I was wondering what any of you can tell me about remedies for wild parsnips? I am just getting over a 6 week long bout of this. Second time I have ever had it in my 61 years, and have never gotten poisin ivy ! My acupuncturist had it a month before I went to her. She says it is systemic and would be in my system for min. of 4 weeks. It doesnt itch, just weeps, and weeps !
    Thank you for any info you can give me !

  4. Kim says

    I have used colloidal silver myself. I make my own, so it is very cheap. What really seems to work is using the silver with any kind of soap. I put a few drops on the soap to wet it and then rub it on the affected area. Stops the itch for about 3 – 6 hrs & then re-apply.

  5. Rebecca says

    Great article! I’m ashamed to say, I believed every single one of those myths! Guess I don’t know my poison ivy, oak and sumac info. I can’t remember the last time I had an encounter with poison ivy (knock on wood), but I’m always trying to keep an eye out to make sure my two-year-old doesn’t end up in a patch of it. I’ll keep these tips in mind. Thanks 🙂

  6. Kerry says

    My hubby is extremely sensitive to poison ivy as well. All summer long he has small break outs that travel around his body. He even ended up with poison ivy one year when his parents had a real christmas tree- even though he never touched it somehow he ended up with it. I will definitely share some of the ideas with him. Right now Technu works if he knows he has been exposed.

  7. Laurie says

    I used jewelweed when I accidentally brushed against poison ivy and it worked wonderfully – apparently it deactivates the urushiol. But it has to be used almost immediately. I am now recovering from a systemic (yeah, I am almost a redhead) poison ivy reaction and I was not aware I touched it, in fact I think I touched something from someone’s campsite who was camped in poison ivy. I used an ointment I had made from jewelweed and plantain and it only spread the rash because it was oily 🙁 although it works on bug bites (I originally thought they were spider bites). Then it broke out all over the place. Calamine was the best, drying it up, as it was really oozing, then I used tea tree oil in the last stages. Relief! I have tried cortisone before and it drove me crazy too. That time I patted a dog! So, ever vigilant…

  8. dede says

    Hi, being from the old generation our remedy for poison ivy is Javex. That’s is what they use in one hospital that I know. 1 cap for 2 of water. My husband seem to attract poison ivy. that is the only thing that works for him. and it works well Put on 3 or 4 times a day. Blessings dede

  9. Jaime Warren says

    I, like others, am highly allergic to poison ivy. While I have currently only tried an OTC remedy (Zanfel, that works great, I will also recommend an quick itch relief of Aloe Vera Gel, it’s cold and takes some of the itching away. Zanfel is unfortunately expensive, but the aloe vera comes in handy.

    At this point I’ve tried everything from the shots, other OTC creams, steroid pack (which does help when it’s on my face). Plus I get it from everywhere. I know you say it’s not contagious but the oil is easy to spread. I once got it from the dog, who had just came out of the woods in the middle of January! At that point (and even now) I do not go in the woods, or other tree lines. Kinda sad, but I would rather not itch or have the rash near my eyes again! Hopefully I’ll never need the remedies you suggested, but I’m willing to try them!

    • Matt Jabs says

      Well the oil is contagious if not removed, to clarify, “The rash is not contagious but urushiol oil can be spread if not removed by washing.” And yes, if the oil is on the dog or anywhere else, the rash will keep appearing until the oil is removed. Most people think the rash itself, and blisters, are contagious, but without the oil they are not.

      I think you’ll have good results with this treatment Jaime, good luck and let us know how it goes (but hopefully you don’t get it again anytime soon).

  10. Hero says

    I am hypersensitive to poinson ivy. If I get a small rash of it anywhere on my body, I will break out in blisters everywhere. Not as intense as the direct contact area but still awful nonetheless. A couple years ago I found the only thing outside of immediate cold water and alcohol rinse that will remove the oil and dry up the rash. TECHNU EXTREEME! It is a cream wash that has gritty pieces in it and releives the itch, drys the rash, and removes the oils. I have to shower with cold water all summer long and must use Technu Extreeme or the Tennessee Valley Death Vine will engulf me. Signed, Fair Skinned Redhead.

  11. h klepko says

    Essential oils are very effective. Rose or Lavender are the most effective, you can also use Roman Chamomile and apply on location (just dilute 2-3 drops in 1 tsp. oil before application).

  12. Marla B. says

    Thanks for sharing this valuable information. I am very sensitive to it…to the point of using steroids to rid the reaction. I keep Fels Naptha soap around for my laundry soap recipe. Next time I run into it, I will reach for it instead of the OTC mess that does not work for me.

  13. todd kalionzes says

    to relieve the itch, get in the shower put hot water as hot as you can stand on effected area then as you get used to the temp keep turning the temp up. a hand held nozzle works best

  14. Anne Smith says

    I have not tried it for poison ivy…I got a bee sting and had just heard about it. I was at the park with my grandkids and looked for the ‘weed’ and found it very quickly…pinched the leaves and put it on my arm…the swelling went down almost instantly. works for many things…a friend of mine used it on a spider bite….redness and swelling went almost immediately

    • Matt Jabs says

      Man, wish I would’ve known this a few days back because for the first time in probably a decade I was stung, three times actually. It swelled up and itched very bad, and 5 days later is still red but almost gone. Next time I’ll be sure to give Plantain a shot.

      • Karen says

        To relieve the pain & swelling of a sting, apply fresh onion cut across the rings – held in place or taped. I used this for a yellow-jacket sting and it relieved it in short order! It also works for a bruise with swelling. This is from a great book, “The Ten Essential Herbs” by Lalitha Thomas.

  15. Susi Matthews says

    I am horribly reactive to poison ivy after having been immune to it in my youth. Once having discovered it, I have complete and utter faith in Jewelweed; it has worked wonders for me and is the *only* thing that has truly worked for me. Tecnu doesn’t work at all; my skin is too sensitive for lye soap and the vinegar with a penny in it feels good but doesn’t do anything for the rash/

    At the beginning of 2012 I moved into a new house so this Spring was a new adventure in finding the poison ivy and poison oak. I had some jewelweed soap and ointment but it was more than 2 years old and I didn’t realize it had lost its effectiveness. It very quickly spread from one spot on my finger to the entirety of my left forearm, my chest, my neck and started onto my ear and face.

    Had to go to the doctor; one round of Prednizone didn’t do a thing so I had to go for a second one, and prednizone makes me literally crazy and very sick but it had to be treated. It finally dawned on me to order some fresh Jewelweed from When it came and a lathered up, I immediately felt relief and within a couple of days, the rash started healing and the horrid itching began to dissipate.

    What folk don’t always think of is that the oil can get on your bedsheets and spread that way; clothing and towels as well. Now when I go out to work in the yard, I automatically wash down my arms and feet with the jewelweed soap and apply the salve.

    I have considered growing the stuff myself but have read that jewelweed is horribly invasive so while I am a real DIY-er, this is something it is easier to order online.

      “What folk don’t always think of is that the oil can get on your bedsheets and spread that way; clothing and towels as well. Now when I go out to work in the yard, I automatically wash down my arms and feet with the jewelweed soap and apply the salve.”

      That is great advice Susi.

  16. Monica Layhew says

    Dawn dish detergent works also, not diluted works faster.
    Rub Dawn on rash, leave it on for 10 minutes, rinse first with warm water, rinse again with cool or cold water. Rash clears up within 2 to 3 days. This is not an organic treatment but it does work.

  17. Len says

    Back in the 60’s there was a product called “Ivy Tox”. You put 6 drops of this oil into water and drank it everyday starting about a month before the poison season started. Believe me it worked. I got poison ivy extremely bad. After using this product I did not get poison ivy. Since then this product has seemed to disappear – at least I can’t find any source for it. If anyone knows where to get it – let me know.

      • Len says

        Thanks Matt. It was probably pulled because it worked or because it was a natural product and therefore no one could patient it.

          • Len says

            Matt, I found this site. I think this product is a lot alike the Ivy Tox I remember. The difference – With the older product you put 6 drops in water and drank it every day a couple months prior to poison season. This newer product you take it once a week for about 2 months prior to poison season then you continue taking it once a month thereafter. It is expensive, but I believe it would be cheaper then buying all the other product after the fact. If this keeps you from getting the rash in the 1st place or very minor then it is worth it.


          • Matt Jabs says

            Interesting. The main ingredient in that product is Rhus Toxicodendron, which we listed above. I wonder if Ivy Tox had that, makes sense according to the spelling of the name.

  18. Tracy Andrews says

    We swear by old fashioned lye soap. We buy ours at Silver Dollar City because we are there at least once a year. I’m sure there are other places to buy it as well. We scrub the area with poison ivy until it kind of burns, and then rinse it off. It only takes one or two washings with lye soap before it dries up and goes away.
