Watercress is an aquatic plant species with the botanical name Nasturtium
officinale. This should not be confused with the quite different group of plants with the common name of nasturtium, botanical name Tropaeolum.
Watercress is a rapidly growing, aquatic or semi-aquatic, perennial plant native to Europe and Asia, and one of the oldest known leaf vegetables consumed by humans. It is currently a member of the family Brassicaceae, botanically related to garden cress, mustard, radish and wasabi—all noteworthy for their piquant flavor.
The hollow stems of watercress are floating, and the leaves are pinnately compound. Small, white and green flowers are produced in clusters and are frequently visited by insects, especially hoverflies such as Eristalis flies.
A 100-gram serving of watercress provides 11 calories and is particularly rich in vitamin K (table). It also contains significant amounts of vitamin A, vitamin C, riboflavin, vitamin B6, calcium, manganese, and folate (table). Watercress has low contents of carbohydrates, protein, fat and dietary fiber (table).
Watercress crops grown in the presence of manure can be a haven for parasites such as the liver fluke Fasciola hepatica. Watercress is a known inhibitor of the cytochrome P450 CYP2E1, which may result in altered drug metabolism for individuals on certain medications such as chlorzoxazone.
