Horseradish

True wasabi (Wasabia japonica) is rare; most commercial pastes use horseradish (Armoracia rusticana) as the primary ingredient. Horseradish can trigger allergic reactions (e.g., oral allergy syndrome, contact dermatitis) in individuals sensitized to Brassicaceae family plants (e.g., mustard, cabbage). Cross-reactivity with mustard or rapeseed is documented.
