Rashes caused by a combination of plant contact and sunlight (phytophotodermatitis)
A rash develops in some people when they touch certain plants and then go into the sun. The sunlight converts a chemical in these plants to an allergen, causing an immune system reaction similar to a poison ivy, oak, or sumac rash (allergic contact dermatitis 
). The rash only develops in areas exposed to sunlight.
These plants include:
- Celery, parsley, parsnip, carrot, dill, and fennel.
- Citrus plants (bergamot, lemon, lime).
- Queen Anne's lace.
- Rue and angelica.
- Fig.
