“It’s one of those species that are able to grow where others cannot,” says Linda Radimecky, an interpretive naturalist at Afton State Park in Hastings, Minnesota. Some reactions to poison ivy are relatively mild and can be treated at home using over-the-counter (OTC) medicines or home remedies to relieve discomfort.

But in severe cases, you should seek medical treatment. You can take steps to prevent a poison ivy reaction by wearing protective clothing if you think you might come in contact with the plant, and by properly cleaning your clothes and skin within 30 minutes of a potential exposure.
Common Questions & Answers
How do you know if a plant is poison ivy?Poison ivy plants have groupings of three leaflets, each with a short leaf stem at its base, attaching it to a stalk or small branch that connects to the main poison ivy vine.

The leaflet in the middle of the threesome usually has a longer leaf stem than the two side leaflets. The leaflets are about twice as long as they are wide.What’s the fastest way to cure a poison ivy rash?Most poison ivy rashes clear up by themselves in a couple of weeks, though severe rashes may take longer, and a first-ever reaction to poison ivy can last three to four weeks. Home remedies can relieve the symptoms but do not shorten the duration of the rash.

Your doctor can prescribe treatments that will clear up the rash faster.Will scratching spread poison ivy on your skin?If you have urushiol, the oily resin found in poison ivy, on your skin, you can spread it by scratching or simply touching another part of your body. Once the oil has been washed off, you can’t spread the rash further. But scratching does raise your risk of developing a bacterial skin infection if you break open any blisters.Is poison ivy contagious?Poison ivy is not contagious, but another person who touches the oil on your skin, clothes, gardening tools, sports equipment, or any other object can also develop a rash.

If you think you’ve come in contact with poison ivy, use soap and water to wash your exposed skin, clothing, and any other items that may have touched the plant.How can I kill poison ivy on my property?You can either pull poison ivy out of the ground, apply the herbicide glyphosate to kill it, or hire goats to eat it, if you have a large area. If you decide to pull it out, wear heavy gloves, clip off the stems above the ground, then dig out the roots about eight inches below the plant. If you use glyphosate, follow the directions on the label.

Identifying Poison Ivy More Than Leaves of Three
An important step in limiting your exposure to poison ivy is, of course, knowing what it looks like. Many people are familiar with the phrase, “Leaves of three, let it be” — but according to Radimecky, this usually isn’t enough information to avoid the plant.

First, what does “leaves of three” actually mean? “The leaves each have a leaf stem,” says Radimecky. “On poison ivy, three leaf stems branch from the same spot on the plant.”
The two leaf stems on the sides, she notes, tend to be shorter than the one in the middle.

As for the color of its leaves, poison ivy can vary widely. “Sometimes they’re green, sometimes they’re red. Sometimes they’re shiny, sometimes they’re not,” Radimecky says.

Poison ivy leaves do have a defining feature: They’re not usually symmetrical. “One side of the leaf might not be the same as the other side, and the three leaves on the plant are not identical,” says Radimecky. “That’s very odd in the plant world.”
Poison ivy leaves may be toothed or lobed but may also be smooth-edged.

The plant itself usually isn’t very tall — generally less than a foot high, according to Radimecky, unless it’s climbing the side of a tree or another vertical surface. But in some areas it grows as a bushy shrub, up to four feet tall. (2)
When they’re mature, poison ivy plants grow berries that start out green but develop a whitish hue — “sort of a cream color,” Radimecky says.

One reason poison ivy thrives in areas that have been disturbed is that it prefers at least partial sunlight. “If it’s sunny, it will grow quickly,” says Radimecky. Learn More About What Poison Ivy Looks Like

“Upon future exposure, our immune system becomes activated, leading to significant inflammation.”
In addition to direct contact and touching contaminated items, you can also have a poison ivy reaction by breathing smoke from the plant if it's burned. This can harm your nasal passages and lungs, and can cause a severe reaction in some people. Poison ivy isn’t contagious unless there is still oil from the plant on your skin and you spread it to other surfaces.

You also can’t spread a rash across your body by scratching once you've washed off the oil. If a skin rash appears to spread, it’s probably because the area was already exposed and it's experiencing a delayed reaction. Or you may have oil from the plant under your fingernails, or you've unknowingly touched a contaminated item.
