Which part of the plant does poison ivy NOT contain oleoresin?

Poison ivy, scientifically known as Toxicodendron radicans, is known for containing an oily resin called urushiol, which is responsible for the allergic reactions many people experience upon contact with the plant. The oleoresin, or urushiol, is primarily found in the leaves, stems, and flowers of the plant.

The wood, however, does not contain oleoresin. This lack of urushiol in the wood is significant because it means that if individuals are cutting or handling wood from a poison ivy plant, they might not encounter the allergic response typically associated with exposure to the leaves, stems, or flowers. Understanding this component of poison ivy can help individuals avoid allergic reactions while engaging in activities such as managing vegetation or working in areas where poison ivy may be present.

Therefore, knowing that the wood does not contain oleoresin aids in effectively addressing safety measures and risk management when interacting with this plant.
