Wasabi (Wasabia japonica) known as Japanese horseradish is a member of the Brassicaceae family. Wasabi is enjoyed with sushi and sashimi, and the associated active ingredient is allyl isothiocyanate (AITC). However, AITC does not exist in wasabi and is only formed immediately upon finely grating the rhizome. Accordingly, a glucosinolate known as sinigrin is present in the rhizome and reacts with the enzyme myrosinase upon grating and generates AITC via a Lossen rearrangement.
Wasabia japonica is a medicinal plant with associated medical properties such as anti-inflammatory, antimicrobial effects, antiplatelet effects, anticancer effects including antioxidant properties. The PubMed database contains nearly 100 research articles on the medical uses of Wasabia japonica (wasabi) .
