Watercress, the aquatic leafy green vegetable, has a long history as a wild edible consumed by humans. Originally native to Europe and Asia, watercress now thrives in various parts of the world where it can grow in shallow waterways, ponds, streams, and springs. This nutrient-rich plant has been cherished for centuries, with Hippocrates himself using it to heal and treat his patients.
The Culinary Delights of Watercress
In the United Kingdom, watercress has been a common leafy green for centuries and is known for its peppery flavor reminiscent of arugula. It is often enjoyed in cucumber sandwiches, salads, and other side dishes. The leaves are renowned in the culinary world for their unique taste and versatility, with the infamous “watercress soup” being a popular dish.
A Nutritional Powerhouse
Watercress is not only delicious but also incredibly nutritious. It is packed with antioxidants and various phytonutrients such as carotenoids, chlorophyll, and phenolic compounds. These compounds have been shown to have numerous health benefits, including potential anti-cancer properties.
Identifying and Harvesting Wild Watercress
If you’re interested in foraging for watercress, it’s important to know how to identify and harvest it properly. The leaves of watercress are rounded when young and can develop a more pointed oblong shape as they mature. It is best to harvest watercress early in the season, before or during its flowering phase when the leaves are a vibrant green color.
Watercress typically grows in slow-moving streams, springs, and alkaline waterways. Its stems are hollow, allowing the plant to float on the water’s surface. When harvesting, it is recommended to cut the plant at the stem with scissors, making sure to leave the roots intact. The stems, flowers, and leaves are all edible and can be enjoyed in a variety of dishes.
The Health Benefits of Watercress
Scientific research has shown that watercress is rich in antioxidants, chlorophyll, carotenoids, and various phenolic substances. These compounds have been linked to a reduced risk of cancer, improved antioxidant status, and potential protection against eye diseases. Watercress is particularly high in isothiocyanates, such as phenethyl isothiocyanate (PEITC), which have been studied for their ability to inhibit tumor growth in certain types of cancer.
Watercress is also a good source of vitamin K, vitamin C, vitamin E, vitamin A, folate, and minerals such as calcium, magnesium, potassium, phosphorus, and manganese. It even contains omega-3 and omega-6 fatty acids.
