Watercress is among the oldest known leafy vegetables consumed by humans, with its use dating back to ancient Greece and Rome. It was revered for its health benefits, including its use as a remedy for various ailments. 


Watercress cultivation spread across Europe, becoming a staple in salads and soups. Its historical significance is not limited to nutrition; watercress has been used in traditional medicine for its purported healing properties, illustrating the deep-rooted belief in its health benefits.

Scientific Makeup

Watercress (Nasturtium officinale) is a member of the Brassicaceae family, sharing kinship with kale, broccoli, and mustard greens. It is rich in vitamins A, C, and K and minerals such as calcium and manganese.

Watercress also contains potent phytochemicals like glucosinolates and antioxidants, contributing to its health-promoting properties. These compounds are the foundation of its acclaimed benefits, from antioxidant support to anti-inflammatory effects.
