Watercress

 
 Overview:

Watercress is an aquatic perennial herb native to Europe. The plant has stems that range from 1 foot to 3 feet in length and float along the surface of running water. Heart shaped fleshy leaves are attached to the stem and are accompanied by small white flowers that bloom on the end of each stem. Watercress has been cultivated for thousands of years. It was used by ancient Greek and Persian soldiers as a tonic to improve their endurance. Native Americans sued watercress for liver and kidney problems and to dissolve gallstones. The German Commission E recognizes watercress for the treatment of respiratory infections. It is also traditionally used in Chinese medicine as a treatment for gingivitis.
