You can probably spot poison ivy if you were looking out for it, right?
Leaves of three, let it be…
You know the problem though, right? Most of the time, you aren’t actually looking out for it.
Spotting Poison Ivy
It would be nice if we got a warning anytime we were going to be around poison ivy.
Or if someone was nearby to point it out to us.
That’s not usually going to happen, so you need to learn how to spot poison ivy if you want to avoid it.
What’s the first step in learning how to spot poison ivy? Understanding where poison ivy is likely to be growing.
Any “wild” area, especially along tree lines and fences, just off paths and trails, and around ponds and lakes, are likely places you will find poison ivy.
If you really want to avoid getting a poison ivy rash when you are outside in an area that might have poison ivy plants, it is likely a good idea to wear long pants, a shirt with long sleeves, gloves, and boots. There are also products, like IvyX, that you can apply to your skin that are supposed to protect you from poison ivy oils.
Identifying Poison Ivy
While it is a good rule of thumb that you might run into poison ivy in a wild area, in some parts of the country, you might even encounter poison ivy in your own backyard. That’s why learning how to identify poison ivy plants is so important, especially if you or your kids have severe reactions to these plants.
What’s the key to identifying poison ivy? That’s right – think of the old adage – leaves of three, let it be.
There is a little more to it than that though. After all, other plants have three leaves. If you really want to be a pro at identifying poison ivy, you also need to know that with poison ivy:
- the middle leaflet has a longer stalk (petiole) than the other two
- leaflets are fatter near their base, but are all about the same size, are green in the summer, and can be red in the fall
- you can sometimes find poison ivy plants with clusters of green or white berries
- their stems don’t have thorns, but do have aerial roots, which help them cling to trees and fences
Most importantly, understand that even a dead poison ivy plant or a plant without leaves can trigger a reaction.
Thinking about burning poison ivy? Don’t! Inhaling the smoke from a burning poison ivy plant can be deadly.
What about poison oak and poison sumac?
They look very similar (well, except poison sumac, which has 7-13 compound leaflets, instead of just 3), but unlike poison ivy, which grows as a vine, these other plants that can cause the same type of reaction grow as a low shrub (poison oak) or a tall shrub/small tree (poison sumac).
Avoiding Poison Ivy Rashes
If your kids are active and adventurous, it is likely going to be a little harder to avoid poison ivy than for kids who rarely go outside.
And even if they get good at spotting poison ivy, the next time they spot it, might be when they are climbing down a tree that is covered in it.
What can you do if your child is exposed to poison ivy?
- You can quickly cleanse the exposed areas with rubbing alcohol. How quickly? You have about 10 to 15 minutes to prevent a poison ivy reaction after an exposure.
- Next, rinse the exposed areas with cool water. Don’t use soap, since soap can move the urushiol around your body and actually make the reaction worse. It is the urushiol oil from the poison ivy that actually triggers your poison ivy rash.
- Don’t forget to scrub under your nails with a brush.
- Now, take a shower with soap and warm water.
- Lastly, put on disposable gloves and wipe everything you had with you, including shoes and tools, etc., with rubbing alcohol and water. And wash the clothes you were wearing. It is possible that urushiol that remains on these things could trigger another reaction if you touch them later.
Instead of rubbing alcohol, several over-the-counter products are available, like Zanfel, IvyX Cleanser Towelettes, and Tecnu Extreme Poison Ivy Scrub or Cleanser.
You could even use a degreasing soap (dishwashing soap, like Dawn). One group of dermatologists has suggested that you could prevent a poison ivy rash after getting exposed by using a damp washcloth and liquid dishwashing soap, washing for three minutes with “repetitive, high-pressure, single-direction wipes under hot, running water.” Repeat this full body wash two more times within one to two hours of your exposure.
If these methods don’t work and your child gets a poison ivy rash, look for treatments to control the itching and inflammation, which will likely mean visiting your pediatrician for a prescription for an oral steroid (tapered over two to three weeks to prevent a rebound rash) and a steroid cream. In addition, other anti-itch treatments and home remedies can be helpful, including an oral antihistamine, calamine lotion, oatmeal baths, cold, wet compresses made with Domeboro powder packets (modified Burow’s Solution), etc.
Keep in mind that without treatment, poison ivy rashes typically linger for about three weeks. Fortunately poison ivy isn’t contagious, so you wouldn’t have to keep your child our of school for that long, but except for very mild cases, see your pediatrician for treatment if they have poison ivy.
