A friend who has celiac was visiting the other day and we were joking about how basically to eat healthy in america you need to go back to 1815--if your great great grandmother wouldn't recognize it as food, then don't eat it.

It is also used as a painkiller and for arthritis and has anti inflammatory properties.
