About 85% of people are allergic to the urushiol present in poison ivy.
Scientists estimate that about 85% of the population is allergic to the urushiol present in poison ivy, poison oak, and poison sumac. A very small amount of urushoil causes a rash - a billionth of a gram is enough to cause a reaction. However, the rash may take more days to present itself or not exhibit at all until after the first few exposures.
