So then I researched what to do with it. Supposedly you have to divide and transplant frequently to keep the root at full potential. Then as already stated, lots of tissues and nose plugs, open windows and fan blowing when processing.
The fresher the more potent - to the point of "be careful!"
Well, if you have a horseradish plant, you are going to have to take a lot of work to bring it to up to where it would be even a food spice. Generally horseradish picks up spiciness by breeding and work on it, lots of things like making the soil a certain content. I know some people who have some cuttings, if you want to go that way. You have to feed the plant quite a bit, and it takes some skill. And you "might" get some horseradish that is similar than you could get at the store, yours could be awesome, I'd be happy to see your progress.
