Watercress, or Nasturtium officinale, is a rapidly growing aquatic plant found in the shallow running waters of the United States, Europe and Asia. Bright green in color, watercress has a unique peppery flavor and has been cultivated since ancient times for its nutritive and medicinal value.
Referred to as the "cure of cures" by Hippocrates, watercress is very low in calories and fortified with more than 15 essential vitamins and minerals, including calcium, vitamin K, vitamin C and vitamin A. Watercress has blood cleansing and anti-inflammatory properties and is used to treat gout, coughs and arthritis. Watercress can also help to relieve fluid retention. Watercress is a suitable choice for salads, sandwiches and soups.
