Well, just a few years ago when I did road races, I learned that you need to drink water and keep hydrated. I also learned that for Marathon runners (not me) you could die from drinking too much water. So I guess unless there are more reported cases and more evidence that Nandina does more harm than good, I am leaving mine. I never thought about it, but I guess all our native plants were probably not native in the beginning, but adapted and evolved into what we know today.
