Horseradish

Armoracia rusticana

Anti-tumourmoderate evidence

Horseradish contains sinigrin — a glucosinolate that converts to allyl isothiocyanate (AITC), which inhibits colon, lung, and stomach cancer cell growth. AITC activates Phase 2 detoxification enzymes similar to sulforaphane from broccoli. Fresh grated horseradish is far more potent than prepared horseradish in jars.
