Toxicodendron diversilobum, also known as Pacific poison-oak or western poison-oak, is a woody shrub or vine found throughout western North America. This plant has been used functionally in the past by some native North American Indian tribes, but it should be handled with extreme caution because of its potential toxicity. The leaves can be collected as they fall in autumn for use as a brown dye or mordant, while the plant's seeds produce an oily substance that can be used to make candles. However, it is important to note that all parts of this plant contain urushiols, which can cause severe allergic reactions if contacted by humans or pets. Despite this, the plant plays an important role in local ecosystems, serving as a food source and shelter for various wildlife species. In some situations, it can also be a component of wildlife gardens and natural landscaping.
