fitofototossicità involves an inflammatory reaction caused by the combination of a photosensitizing agent of the plant, followed by exposure to ultraviolet rays, modifying the molecule so that it becomes harmful.

The fitofotodermatiti arise gardening, working with fruit and vegetables, or jogging through medication and cosmetics.
The main species of plants that cause fitofototossiche fitofotodermatiti are UMBRELLIFEREAE (part of APPIACEAE ) and Rutaceae . The
fitofototossicità in these plants is caused by FUROCOUMARINE , which is probably used by them as a natural defense against fungi in fact, when attacked by fungi, increase the production of this substance up to 300 times.
E 'sufficient only a microgram of FUROCOUMARINE in a square centimeter of skin to induce the production of a bubble. Among the Rutaceae Ruta graveolens has a long history in folk medicine as a remedy for hives, warts and erysipelas, and is also the most frequent cause of phototoxicity in the gardens of Britain.
