For such tiny fruits, celery seeds pack a punch in more ways than one.
First, the seeds are a rich source of antioxidant flavonoids and an
omega-6 fatty acid called linoleic acid. The seeds also provide lutein,
a type of carotenoid that has received a great deal of attention in
recent years for its potential role in helping to prevent macular
degeneration.
Caution is advised, however, for individuals who take certain
pharmaceutical medications. Celery seed contains bergapten, an organic
chemical compound composed of a five-membered aromatic ring of furan
fused with coumarin. This means that large doses of the seed might
increase the effects of anticoagulants and antiplatelets, such as
warfarin (Coumadin). This compound also known to increase
photosensitivity.
