Celery Juice: It's Trendy, but is it Worthy of the Hype?

8. Consumer Beware

Celery belongs to a group of foods that are known to induce allergic reactions. Symptoms may range from a headache and rashes to anaphylactic shock. Individuals who are allergic to mugwort and birch pollen should avoid celery and its juice. People who take anti-clotting medication should consult their physician about celery consumption, as it contains the blood-clotting component vitamin K. Celery may increase photosensitivity, and ingesting high amounts may cause skin inflammation. Individuals with kidney problems should not consume celery juice. People facing surgery should not use this product for at least two weeks before a procedure, as it may interact with anesthesia and adversely affect the nervous system.
