1 If you can rinse your skin immediately after touching poison ivy, poison oak, or poison sumac, you may be able to rinse off some of the oil. If not washed off, the oil can spread from person to person and to other areas of your body.  Wash your clothing.
The rash that you get from poison ivy is caused by a chemical in the sap called urushiol. This chemical penetrates the outer layer of skin until it hits the dermis, and in the dermis an allergic reaction to the urushiol occurs. (See How Sun Tans and Sunburns Work for a good description of your skin and how it works.). Urushiol does not spread through the body (although it may appear to because of the delay in symptoms caused by differing skin thicknesses). 2  The blisters that form are also not contagious.. 3  They do not contain urushiol.
