What is Poison Ivy?

Poison ivy or toxicodendron radicans, is a poisonous Asian and Eastern North American flowering plant.  This plant is known to cause an itchy, irritating and sometimes painful rash called urushiol- induced contact dermatitis.  The rash is caused by urushiol (you-ROO-shee-all), a clear liquid compound found in the plant’s sap.  Toxicodendron radicans varies in appearance and habit.   It is not a true ivy, but rather a member of the cashew and pistachio family.

How do you identify poison ivy?

Poison ivy has four main characteristics.

  1. clusters of three leaflets
  2. alternate leaf arrangement
  3. lack of thorns
  4. each group of three leaflets grows on its own stem

Toxicodendron radicans can be found throughout much of the US and parts of Canada east of the Rocky Mountains. It usually grows in wooded areas, especially along the edge of forests where the tree line breaks and sunshine filters through.  You can also find it in exposed rocky areas, open fields, and disturbed areas.

What are the early signs of poison ivy?

The rash often does not appear until 12-72 hours after you come in contact with urushiol.  The first sign is itchy skin.  After that, you develop redness or red streaks.  The red streaks then turns into hives and swelling.  After the swelling you will experience an outbreak of small or large blisters, often forming streaks or lines.  Once the blisters burst your skin will begin to crust.

How do you treat poison ivy?

Blisters from the poison ivy rash may be treated with calamine lotion, Burrow’s solution compresses, dedicated commercial poison ivy creams, itch creams or baths. Over the counter products can help ease the itching.  Dermatologists are now recommending oatmeal baths and baking soda.

There is a new plant based remedy used to treat urushiol-induced contact dermatitis.  This remedy is called jewelweed. Mash made from the living plant is effective in reducing urushiol dermatitis.

How long does it take for poison ivy to go away?

The rash should go away in a few weeks.  If it takes longer or you or your child experiences severe swelling go and see a doctor right away. If you have trouble breathing or swallowing, go to an emergency room immediately.
