Horseradish

Horseradish is a member of the Brassica family, like broccoli and Brussels sprouts.
Like other Brassica, horseradish contains significant amounts of glucosinolates— compounds that have been shown to increase the liver’s ability to detoxify carcinogens and that may suppress the growth of cancerous tumors. But horseradish is especially rich in these compounds, providing ten times as many of them as broccoli does.
Horseradish is also said to aid digestion and contains compounds known to fight pathogens in food, such as Listeria, E. coli and Staphylococcus aureus.
