Wasabi is a rich source of chemicals known as isothiocyanates. These are the same anti-cancer chemicals found in broccoli and cabbage. These isothiocyanates appear to activate enzymes in the liver which detoxify cancer causing substances before they can do damage to the body. They also appear to interfere with other steps in the formation and metastasis of cancer cells. More importantly, they exert their anti-cancer effects without damaging normal cells.
