Benefits of Celery
The natural laxative effect of celery helps to relieve constipation. It also helps relax nerves that have been overworked by manmade laxatives. In the store, buy fresh leaves and stem with bright green color and crispy in appearance. Avoid any slump, shriveled stems, dry, yellow, and spoiled leaves since they are out of flavor.
