"Some foods and medications contain photosensitizing agents; figs, limes, parsnips and celery root are all in this family. While some act only when applied topically, consumption of celery root could cause some people to be hypersensitive to skin exposure from UV radiation. If you like celery root in your salad you might opt for more carrots instead. If you are taking medication you should consult your physician to determine any potential effects related to UV radiation."
