What is Allergic Phytodermatitis?
Allergic phytodermatitis is a skin reaction caused by contact with certain plants, most commonly poison ivy, poison oak, or poison sumac. These plants release an oily resin called urushiol, which triggers an allergic response in sensitized individuals. The result is redness, itching, blistering, and discomfort that can persist for days to weeks.
Common Causes
- Poison Ivy, Poison Oak, Poison Sumac – the most frequent triggers.
- Other Plant Allergens – such as wild parsnip, giant hogweed, or certain ornamental plants.
- Cross-Contamination – urushiol can stick to clothing, pets, or gardening tools, spreading the reaction.
Symptoms
- Intense itching and burning
- Red, inflamed rash with small bumps or blisters, often linear.
- Swelling and tenderness in affected areas
- Fluid-filled blisters that may ooze or crust over
