Horseradish (Armoracia Rusticana) is a Brassica that has been cultivated since ancient times and highly prized throughout Asia and Europe for its tender leaves and fleshy white roots, which have a delicious intense pungency and are rich in bioactive sulfur-containing isothiocyanates. Its anti-microbial properties make it useful for pickling, fermenting and preserving food and horseradish is used throughout Europe for treating fever, sore throat, cough and flu as well as a condiment acidified with vinegar as well as being used as the bitter herb of Passover, a remedy for scurvy, an aphrodisiac, an expectorant and pain-relieving poultice or rub.
