 "The parsnip is usually cooked but can also be eaten raw. It is high in vitamins and minerals, especially potassium. It also contains antioxidants and both soluble and insoluble dietary fiber. It can be cultivated in deep, stone-free soils and is attacked by the carrot fly and other insect pests, viruses and fungal diseases, of which canker is the most serious. In sunlight, handling the stems and foliage can cause a skin rash... While the root of the parsnip is edible, handling the shoots and leaves of the plant requires caution as the sap is toxic. Like many other members of the family Apiaceae, the parsnip contains furanocoumarin, a photosensitive chemical that causes a condition known as phytophotodermatitis. The condition is a type of chemical burn rather than an allergic reaction, and is similar to the rash caused by poison ivy." \\
