Wasabi
Wasabia japonica
Wasabi contains isothiocyanates — particularly 6-methylsulfinylhexyl isothiocyanate (6-MSITC) — that activate Nrf2 detoxification pathways, induce apoptosis in cancer cells, and inhibit metastasis. Japanese research has shown activity against colorectal, lung, and breast cancer cell lines. Wasabi isothiocyanates are more stable and bioavailable than those from horseradish or broccoli.
Medicinal Properties
Cancer Types Studied
Recommended Dosage
Fresh wasabi root grated: 1–2 tsp daily. Wasabi extract standardised to isothiocyanates: 50–100 mg daily. Note: most commercial wasabi paste is horseradish — use genuine Wasabia japonica.
Preparations
Fresh Grated Root
Grate fresh wasabi root on a ceramic grater just before use. The volatile isothiocyanates are most potent when freshly prepared. Use 1 tsp with sushi, sashimi, or vegetable dishes.
Wasabi Extract Capsules
50–100 mg standardised extract daily. Ensure the product specifies Wasabia japonica, not horseradish (Armoracia rusticana).
