The Greeks regarded watercress as a psychic stimulant and the Romans used with vinegar as a remedy for mental disorders. Old English physicians recommended its use as a remedy for headaches and biliousness.
Watercress is a native of Europe. It is widely distributed in a wild state in Great Britain, South and Central Europe and Western Asia. This plant is now cultivated in Malaysia, Indonesia, Hawaii, West Indies and East Africa and grows in the Himalayas.
