The wasabi plant grows naturally along stream beds in mountain river valleys in Japan, but is cultivated in certain regions in Japan and North America. Traditionally, the root is shredded to create a pungent condiment used with fish, especially sushi. In laboratory studies, wasabi has inhibited cancer cell growth and survival. However, one wasabi constituent also promoted cancer cell growth. Wasabi has also shown anti-inflammatory activity, antiplatelet activity, and anabolic bone metabolism activity in laboratory tests. However, there is currently insufficient available evidence in humans to support the use of wasabi for any indication.
