True wasabi - Wasabia japonica- is a member of the Brassicaceae family of vegetables which includes cabbages, horseradish and mustard.
Packed with powerful cancer-fighters called isothiocyanates, wasabi helps to stimulate the detoxification enzymes in your liver that disarm free-radicals and carcinogens.
HEALING TIP: Be sure to look for real wasabi, which comes powdered in a can or fresh in root form. Most wasabi in sushi restaurants is colored horseradish.
