Watercress is among the oldest known plants consumed by humans, and claims for its medicinal powers are almost as ancient. Hippocrates grew it near his hospital for medicinal purposes; Pliny the Elder favoured it as a remedy for anxiety and coughs. At one time or another its peppery leaves have been used as old folk remedies to treat fever, scurvy, intestinal worms and baldness.
Even now, watercress maintains a reputation as a nutrient-rich superfood – the US Centers for Disease Control and Prevention has ranked it number 1 (with a perfect score of 100) on a list of “powerhouse” fruits and vegetables, and with good reason: it’s rich in vitamins C, K and A and antioxidants.
