Anti Fungi and Anti bacteria benefit from Wasabi and Horseradish
In the Journal of Biofactors, 2000, a study has been published detailing the functional properties of wasabi and horseradish. The study was released from the School of Food and Nutritional Sciences, University of Shizuoka, Japan stating that Wasabi (Wasabi japonica) and horseradish (Cholearia arnoracia) contains a potent component Allylisothiocyanate (AIT) that shows inhibitory effect on the growth of food poisoning bacteria and fungi.
Antioxidant and Anti Cancer Benefits from Horseradish
In the same study, it has been found that Allylisothiocyanate (AIT) in wasabi and horseradish has a functional antioxidant property in vitro. The superoxide scavenging potency of horseradish inhibits the mutation toward 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline [MeIQx], a well-known mutagen/carcinogen in broiled fish and meat. The results of the study suggest that wasabi and horseradish are functional foods that provide many health benefits.

Another study found in the Journal of Agricultural and Food Chemistry. March 2005 reported that horseradish (Armoracia rusticana) and Wasabi (Wasabia japonica).have tumor cell proliferation and cyclooxygenase inhibitory constituents. Horseradish and wasabi constituents at a concentration of 60 microgram/mL inhibited the growth of colon, lung, and stomach cancer cells by 28, 17, and 44%, respectively. This is the first report of the COX-1 enzyme and cancer cell growth inhibitory monogalactosyl diacylglycerides supported the anticancer benefits from wasabi and horseradish rhizomes.
Immune Boosting Benefits of Horseradish
In the Journal of Cell Biology, a report was published detailing the interaction of particulate horseradish peroxidase (HRP)-anti HRP immune complexes with mouse peritoneal macrophages in vitro. Results have shown that the extensive capacity of macrophages to interiorize and destroy large amounts of antigen after the formation of antibody illustrates a role of this cell in the efferent limb of the immune response.

Other studies suggest that horseradish stimulates the production of leukocytes and phagocytes, which are two important immune-supporting antibodies.
