Water cresses are fast-growing, aquatic or semi-aquatic, perennial plants native from Europe to central Asia, and one of the oldest known leaf vegetables consumed by human beings. It is an invasive species in the Great Lakes region where it was first sighted in 1847. These plants are members of the Family Brassicaceae or cabbage family, botanically related to garden cress and mustard — all noteworthy for a peppery, tangy flavor.
The hollow stems of watercress are floating and the leaves are pinnately compound. Water cresses produce small white and green flowers in clusters.
Watercress is particularly valuable for its antiscorbutic qualities and has been used as such from the earliest times. As a salad it promotes appetite. Culpepper says that the leaves bruised or the juice will free the face from blotches, spots and blemishes, when applied as a lotion.
Watercress contains significant amounts of iron, calcium and folic acid, in addition to vitamins A and C. In some regions watercress is regarded as a weed, in other regions as an aquatic vegetable or herb. Watercress crops grown in the presence of animal waste can be a haven for parasites such as the liver fluke Fasciola hepatica.
Many benefits from eating watercress are claimed, such as that it acts as a stimulant, a source of photochemical and antioxidants, a diuretic, an expectorant, and a digestive aid. It also appears to have cancer-suppressing properties; it is widely believed to help defend against lung cancer. Due to its high iodine content, watercress has a strengthening effect on the thyroid gland, thus beneficial for suffers of hypothyroidism.
In addition, watercress is a known inhibitor of the Cytochrome P450 CYP2E1, which may result in altered drug metabolism for individuals on certain medications (ex., chlorzoxazone).
