Yes, but a checkbox in the database tells them what, exactly?
Currently, there's a checkbox in the database for "Toxicity: Leaves are poisonous". A search on that field returns 34,999 results, truth be told it probably should return at least ten times that many results since most plants produce toxic chemicals of one sort or another. How many of those plants have harmed anyone, anywhere in the world, since let's say the turn of the century just to put an end date on it? Almost none. It's really a meaningless bit of information without any context.
