furanocoumarins
Light-activated plant toxins
Furanocoumarins are organic compounds found in certain plants—particularly citrus fruits, celery, parsley, and figs—that can cause skin reactions when exposed to sunlight.
This phototoxic effect makes skin burn or blister after contact with the plant followed by sun exposure, a condition called phytophotodermatitis.
Grapefruit juice contains furanocoumarins that interfere with drug metabolism, which is why medication labels sometimes warn against grapefruit consumption.
