i'm extremely sensitive to urushiol even to the point of reacting to contact with mango skin. like others here i can verify that poison oak can react over a long period of time. back in august my cat escaped into the california woods covered with poison oak. i retrieved him but two days later i had one of the worst reactions on my arms that i imagine any human has ever seen. it's now april (8 months later) and the poison is still slowly seeping out of my arms. every week or two a single tiny hole opens up releasing some of the toxin and reacting to it. then over a span of days it will heal. however shortly after it heals another hole (or inflamed pore) will like clockwork open up in a different place on my arm to take its place. i see this as my body slowly purging the urushiol from skin and fat cells in which it has become entrapped. fortunately these subsequent reactions have been small and gradual over time. for those who experience a full blown emergence of the rash without repeated exposure check to make sure you're not getting urushiol from another source (e. g. mango skin).
