Many people suffer allergic reactions when they come into contact with the poison ivy plant. Contact with an oil on the plant's leaves, known as urushiol, can cause an uncomfortable, itchy rash known as contact dermatitis. You do not have to directly touch the poison ivy plant to develop a reaction; urushiol oil can be transferred to you if it is on clothing, pets, gardening tools—anything that has come in contact with the plant.WebMD: Poison Ivy,Oak,or Sumac - Topic Overview
