I've eaten rattle snake weed, but only because I had it in that garden...
It hitch-hiked in with a load of "free" compost.
Never again.
Getting rid of rattle snake weed is very difficult.
In my experience, none of the plants that it over-runs can be saved.
I have found that a wall to wall carpet over the top of sheet plastic... over the entire patch will eventually kill them.
takes a coupla years...
Left unchecked, this mint relative will blanket the city.
