poison oak
Rash-causing woodland plant
Poison oak is a North American shrub related to poison ivy, with leaves resembling oak leaves that cause an itchy, blistering rash on contact.
The irritant is urushiol oil, present in leaves, stems, and roots year-round.
I brushed against poison oak on the trail and broke out in hives.
The plant turns red in autumn, making it easier to spot—and avoid.
