The leaves and stem of poison ivy contain a poisonous oil that is very irritating to the skin. It is one of the most common and most-feared poisonous plants in North America. Few people can touch the leaves or berries without being poisoned. The poison is an oil that is extremely irritating to the skin, causing it to blister and itch.
Poison ivy is very common, everyone who goes into the woods and fields should learn to recognized it. It always has three leaflets on each leaf. Poison ivy may grove as a vine twining on a fence or as a bush. The leaves are shiny green in the summer, turning scarlet in fall. Later in the season clusters of poisonous white berries form.
