Wasabi (Wasabia japonica, also classified as Eutrema japonicum) is the green-tinged paste familiar from sushi. Authentic wasabi is cultivated in flowing-water beds in regions including Shizuoka and the Izu Peninsula. Cosmetic wasabi root extract concentrates the isothiocyanate compounds responsible for the pungent character.
