Wasabi is a plant native to Japan. It's mainly grown for its roots, which are ground to make a spice. It's sometimes called Japanese horseradish.

Wasabi contains chemicals that may have anticancer effects and anti-inflammatory effects and may also slow blood clotting.

People take wasabi by mouth for heart disease, cancer, stomach pain, indigestion, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse wasabi with horseradish or moringa. These are not the same.
When taken by mouth: Wasabi is commonly consumed in foods. There isn't enough reliable information to know if wasabi is safe to use as medicine or what the side effects might be.
