Learn about poison oak. Poison oak is similar to poison ivy and poison ivy because they are plants in the same family. Western poison oak is the most common poison oak species and grows abundantly along the Pacific coast of Oregon, Washington and California (USA). Western poison oak will grow as small bushes if grown in open space or as vines if grown in dense forests. [1] X Research Source

  • Another poison oak variety is the Atlantic poison oak, which grows in the Southeastern United States. This poison oak is not as popular as the western poison oak. [2] X Trusted Source Centers for Disease Contrp and Prevention Go to source

Be careful when examining poison oak. The best way to avoid a poison oak rash is to never touch a tree that you suspect is poison oak. If you want to get close enough to verify, you should use a stick or put on gloves for a closer inspection.

  • If it is a poison oak tree, you should thoroughly wash the parts of your body that have come in contact with it with soap and water.

Observe the leaves. Poison oak leaves, whether bushy or vine, have a three-leaf (compound) structure. Oak leaves will split into 3 compound separated from the petiole. Leaves are wavy or scalloped.

  • As the name suggests, poison oak leaves have a slight resemblance to oak leaves. [3] X Trusted Source Centers for Disease Contrp and Prevention Go to source

Color test. The upper surface of poison oak leaves is usually glossy green, yellow, red, or brown, depending on the vigor of the tree and the season. The underside of the leaf is usually less green and glossy but smoother than the upper surface. [4] X Trusted Source Centers for Disease Contrp and Prevention Go to source

Learn about other forms of poison oak.

  • In winter, poison oak will drop its leaves and look like a reddish-brown stick (some trees sometimes stick out of the ground and sometimes grow in large clusters) with an alternate base.
  • You can also see poison oak growing as a crisscross of vines, wrapped around a trunk, and sometimes with small budding leaves (depending on the season).

Find out what causes the rash. Both the leaves and stalks of poison oak contain uruship, a plant slime that causes allergic rashes. Uruship is also present in the roots of trees, even in a dead oak tree. [7] X Cleveland Clinic Trusted Source Go to Source

  • In addition, uruship can transform into a gas if the oak is burned and is easily transferred from one object to another.
  • Rashes caused by poison oak are not contagious but uruship is passed from person to person on contact, thus causing a uniform rash.
  • All parts of the poison oak tree contain the toxin uruship. Even poison oak is not safe to lose leaves in the winter. [8] X Trusted Source Centers for Disease Contrp and Prevention Go to source

Identify the rash. Rashes from poison oak exposure can vary from person to person as some people tend to be more sensitive to uruship than others. The rash will generally be very itchy and red, causing red blisters that blister and ooze. The rash ranges from mild to severe, which may be striated and grow in patches.
