The Toxic Component of Poison Ivy

The principal toxic component found in poison ivy is urushiol, an element that is produced in the resinous juice of the resin ducts of the leaves, flowers, fruits, and bark of stems and roots but not in the pollen grains. The dangerous part of this component, strictly found in poison ivy plants is that the urushiol may be carried from the plant on clothing, shoes, or soil, endangering your environment or pets if you have them. The poisoning may occur in cases where the clothing is worn up to a year after contact with poison ivy.

Risks of Touching Poison Ivy

Beware when you touch poison ivy! If this has happened to you, you'll want to know this very valuable information. When poison ivy is touched, the substance (urushiol) produces in many persons a severe, itchy, and painful inflammation of the skin known as contact dermatitis. Some of the most common symptoms of poison ivy on the skin include intense itching, skin swelling and blisters, and skin redness. Normally the symptoms develop within four hours to four days after exposure to the toxic component. After the initial symptoms, allergic individuals develop fluid-filled blisters in a line or streak-like pattern, and although the symptoms are worse within 1-14 days after touching the plant, they can surely develop up to 21 days later if one has never been exposed to urushiol before.

Finally, after coming in contact with poison ivy, remove any contaminated clothing, and wash under very warm or hot running water using dishwashing liquid on a damp washcloth. Wash your entire body three times, while constantly wiping in one direction and not back and forth because it is proven that this helps reduce irritation and help remove the toxic oils.
