The plant is native to the Mediterranean region and is closely related to nutrient-rich vegetables such as broccoli, cabbage, and Brussels sprouts.

Wasabi, or Japanese horseradish, is a cruciferous vegetable that grows naturally along streambeds in valleys in Japan. It also grows in some humid geographic regions. Known for its distinctive pungent flavor and bright green color, wasabi is a staple condiment for sushi and noodles in Japanese cuisine. The isothiocyanates (ITCs) that give the vegetable its flavor may have some health benefits.
