Poison ivy: Signs and symptoms
What you see and feel on your skin is caused by urushiol (you-ROO-shee-all). Urushiol is the oil in poison ivy, oak and sumac. You find this oil in all parts of the plants — the leaves, stems, and even the roots. Within minutes of contact with urushiol, the skin starts to absorb it. But you don't feel this. And you don't see a rash right way.

Rash from poison ivy. Redness, small, itchy bumps (hives), and itchy skin are common.
If this is your first contact with urushiol, you may not see a rash. Or it may take a week for the rash to appear. The rash also can appear within hours or a few days. If you have a reaction to the oil, you can have these signs (what you see) and symptoms (what you feel): - Itchy skin
- Redness or red streaks
- Hives
- Swelling
- An outbreak of small or large blisters, often forming streaks or lines
- Crusting skin (after blisters burst)
- Other parts of the body touch the oil
- You spread the oil on your skin by touching other parts of your body
