What is Poison Ivy Rash?

Scientifically known as toxicodendron radicans is a poisonous plant found in North America. It produces urushiol, the compound responsible for the itching rash that a person acquires from the mere touch of poison ivy. This plant is found in 3 forms: a trailing vine, a shrub, and a vine that grows on trees. We usually see this plant in forests and open fields. People are still victimized by this plant and it’s because they couldn’t identify what a poison ivy looks like.

Here are the following distinct characteristics of poison ivy:

  • They form in clusters of three leaflets
  • Alternate leaf arrangement
  • Lack of thorns
  • Three leaflets grow with its own stalk

This wild plant is truly common that can cause an irritating allergic reaction. The urushiol is a toxic chemical with a mere small amount of exposure to a person can cause contact dermatitis- a rash that spreads all over the skin. This resin content can be transmitted by the fingers or animal fur and can remain dormant for months on clothing, shoes, and tools. Inhaling smoke from a burned poison ivy has a possibility of irritating a person’s eyes or nasal passages. But take note, poison ivy rash isn’t contagious. The fluid containing blister doesn’t contain urushiol and shall not spread the rash to another person.

As the symptoms appear, they may continue to linger for many days up to 2 to 3 weeks due to the delay reaction from urushiols. This may also depend on the amount of the urushiols that a person has made contact with. Fortunately, the spreading of the rashes is not possible for it can only affect the local part inflicted with the resin urushiol.

Inhalation from the smoke from a burnt poison are rare instances but if it takes place: the eyes, airway, and lungs are affected. Complication shall arise when a person scratches the poison ivy rash with dirty nails. The condition may develop to secondary bacterial infection which will lead to blisters with pus drainage.
