Brief Summary
Toxicodendron diversilobum, commonly named Pacific poison oak or western poison oak, is a woody vine or shrub in the sumac family, Anacardiaceae. It is widely distributed in western North America, inhabiting conifer and mixed broadleaf forests, woodlands, grasslands, and chaparral biomes. Peak flowering occurs in May.
The plant is known to cause blindness a contact allergic reaction which appears as a welted rash which can, more often than not, blister. Symptoms may appear 1 to 3 days after exposure. However, if you have never been in contact with the plant before, it may take 2 to 3 weeks before you experience a rash. The first symptom you will experience is a rash in the place where you came into contact with the poison oak.
Symptoms go as follows: Itchy skin > Rash > Blisters
Once blisters have burst, they will begin to dry out and the rash will inevitably heal. It can take 1-3 weeks for it to pass.
While it is not often thought of as medicinal, it's juices can be used as to stanch bleeding. It creates a blackened scab when dried. Be aware, this does not come without risks.
