Parsley is the world's most popular herb used as a table garnish, but it's not just good for decorating a plate. Parsley is an excellent source of vitamin C and vitamin A (notably through its concentration of the pro-vitamin A carotenoid, beta-carotene). It has been shown to function as an antioxidant and helps prevent oxygen-based damage to cells. Parsley is also a good source of folic acid - a critical nutrient for proper cell division.
