Hayek and Sisymbrium nasturtium-aquaticum, which are often encountered in botanical literature. Family: Brassicaceae, formerly known as Cruciferae.

It is cultivated commercially on a large scale in water-based systems and is often sold in bunches in supermarkets and farmers' markets, particularly in regions with a history of its use. It is also available in some health food stores in dried or powdered form, as well as in capsules or tinctures as a dietary supplement. In many temperate regions, it grows wild in clean, slow-moving streams, and it is also a popular plant for home gardens, where it can be grown in pots or containers with a consistent water supply. Its availability has made it an accessible and popular ingredient for both culinary and medicinal applications worldwide.
External Look
Watercress is characterized by its delicate yet vibrant appearance. It has a succulent, hollow stem that allows it to float and grow in water. The leaves are pinnately compound, meaning they are arranged on either side of a central stalk. Each leaf consists of several smaller, rounded or oval-shaped leaflets. The color of the leaves is a deep, rich green. The plant produces small, white flowers with four petals, which are characteristic of the Brassicaceae family. These flowers grow in clusters at the end of the stems. The entire plant has a crisp, fresh texture and a distinctive peppery aroma, especially when the leaves are crushed.
Healing Properties
Watercress is renowned for its impressive range of healing properties, which are attributed to its rich content of vitamins, minerals, and potent phytochemicals. It is an excellent source of Vitamin C, K, and A, as well as important minerals like iron, calcium, and manganese. The presence of glucosinolates, which convert into isothiocyanates when chewed, is responsible for many of its health benefits.

It has been traditionally used to treat various forms of cancer, including breast, lung, and prostate cancer.

Skin and Hair Health: The vitamins and minerals in watercress are beneficial for skin and hair. It has been used topically for blemishes, freckles, and eczema, and internally for conditions like alopecia. Anemia: As a good source of iron, watercress is traditionally used to treat anemia and improve blood health.
