What is poison ivy?
Poison ivy is a plant that grows throughout the United States except in the Southwest, Hawaii and Alaska. It can grow as a vine, a shrub or ground cover and has shiny leaflets with smooth or toothed edges that grow in groups of three. The leaves are reddish in the spring, green in the summer, and orange, red, yellow or bronze in the fall. They may also have greenish-white flowers and whitish-yellow berries.
The oily resin of the poison ivy plant, known as urushiol, is irritating to most people and can sometimes cause severe symptoms when touched or breathed in. The oil is found year round in all parts of the poison ivy plant, including the roots, stems, flowers and leaves.
Poison ivy oil can stay on almost any surface, such as clothing or camping gear, until it is washed off with soap and water or rubbing alcohol. If it’s not washed off, it can even remain for years.
What symptoms does poison ivy cause?
Touching the oil of the poison ivy plant can cause a very irritating rash. This can come from directly touching the plant or from touching other items that came in contact with it, such as sporting or camping equipment, gardening tools, shoes, clothes or pet fur.
It can take up to two days for the rash to develop if you’ve had a reaction before, or up to two weeks if you haven’t. The reaction usually starts with itching, redness and swelling and sometimes is followed by tiny pimples or blisters.
The rash from poison ivy cannot spread from person to person because the rash itself, including any pimples or blisters, does not contain poison ivy oil.
Burning poison ivy can make smoke that irritates the eyes, skin, nose and throat and makes breathing difficult. These symptoms can be severe.
