Where did horseradish get its name?

Horseradish is a commonly occurring plant.

Man has been collecting and using the herbs and plants in his environment since before written record.

Any ingredient that adds as much flavour to foods and has as many medicinal uses as horseradish does is something that quickly went from being gathered in nature as nomadic bands of humanoids passed, to being cultivated by mankind as he himself settled into more permanent domestic situations.
