Poison Oak

Poison Oak is a plant seen briefly in the episode, "Loyal Order of Ingerman" in Dragons: Race to the Edge, Season 6.

Description
Poison Oak is, in fact, not related to Oak trees, nor is it a tree. It is one of two shrubs in the Genus Toxicodendron - the Atlantic poison oak (Toxicodendron pubescens) and the Pacific poison oak (Toxicodendron diversilobum). Both species occur in North America, one in the South Eastern United States and the latter in Western North America. Both have leaves superficially resembling those of some oak trees, leading to the name.

In the Franchise, poison oak is incorrectly portrayed. It is shown as a massive tree trunk with ivy-shaped leaves on the ground.

As a defensive mechanism, poison oaks contain the oil urushiol. The oil is not a poison, but a compound that causes an allergic reaction when it contacts skin. The reaction typically manifests as a raised, itchy red rash near the area of contact. Reactions can vary in severity between individuals.

Function
There is no function of Poison Oak in the Franchise, other than as an irritant and source of humor.

In reality, some Native American cultures used the plants medicinally for various ailments.
