When you have a contact with a poison ivy plant, you will have an itchy blistering rash on your skin, which is called a poison ivy reaction.

The poison ivy rash or poison ivy reaction is caused by oil found in poison ivy which is called urushiol. Urushiol is found in all parts of the plant like roots, stem and leaves. It absorbs quickly through the skin. You can also acquire rash indirectly through gardening tools, camping equipment or an animal fur which has gone in contact with urushiol. The rash can appear to the skin immediately within hours after exposure or for a several days later. The rash does not spread and these skin reactions can be treated accordingly.

While some type of exposure happens when the plant is burned and the smoke it produces is inhaled which can eventually affect your lungs. It will cause extreme pain and can lead to respiratory difficulty and serious allergic reaction.
