Plant dermatitis is an eruption caused by skin contact with certain plants.
The rash may take various forms but is generally itchy, red and swollen.
Common offending plants include poison ivy, Peruvian lily, and English primrose.
Some plants only cause a rash if the sun is shining on the skin at the same time (phytophotodermatitis).
Plant dermatitis is not contagious and the blister fluid does not spread the rash.
The rash appears between four hours and 10 days after exposure to the plant, depending on individual sensitivity and the amount of contact.
Occasionally, new eruptionscan appear after treatment has begun due to blood stream spread of the allergy to other areas.
