You may only know of wasabi for its fiery zing as a popular Japanese condiment. But genuine wasabi is actually a wondrous health-promoting vegetable that has been studied by Japanese herbalists since the 10th century and now in modern times by prominent scientists. Like our watercress and cruciferous sprouts, it is loaded with glucosinolates, precursors for the DNA-supportive compounds known as isothiocyanates. Genuine wasabi is indigenous to cool mountain streams of the remote northern islands of Japan. It takes 18 months for our sustainably harvested wasabi to mature. After harvest, the plants are freeze-dried and tested to ensure they retain the highest concentrations of their active detoxifying compounds.
