Poison ivy is readily identifiable once you get used to really looking at leaves, and know the basic telltale signs. Being able to identify it may not stop you from getting it (after all, someone has to get that football that landed in the shrubs), but it certainly will help you take the proper precautions. In this tutorial, you learn poison ivy's scientific classification, how to identify it, how to protect yourself, what causes the rash, what the doctor can do for you, and what kinds of home cures there are.
