We tend to hold a lot of fear in our guts. Nervousness causes those sensations we know as tummy flips or butterflies in the stomach, and anxiety can run deep through the nervous system, putting our guts in knots. Celery juice restores the entire digestive system. Use it for its calming effects when you are feeling frightened, panicky, shocked, fretful, nervous, threatened, unsure, afraid, or defensive.
