Poison oak, poison ivy, and poison sumac are all members of the genus
toxicohendron, and urishiol is the toxin common to all three of these
plants
that is responsible for allergic dermatitus reaction in humans.

Don't forget cashews - they are a first cousin to poison ivy. For
people who are hypersensitive to poison ivy (me included), eating more
than a small amount of cashew nuts causes a pretty bad internal
reaction.

While it doesn't seem to bother me one bit, my wife is clinically
hypersensitive to the toxin and so it has been the subject of some
fairly
in-depth study on my part.
