Can you explain the differences between poison ivy and poison oak and how to identify and treat them"?

Poison ivy and poison oak are both plants that can cause skin irritation. Poison ivy has three leaflets and can grow as a vine or shrub, while poison oak has three leaflets and grows as a shrub. To identify them, look for clusters of three leaflets with a shiny appearance.
