Well you can find right on Wikipedia that there is not a cure. If you want to get picky, do four seconds of reading instead of blustering and attack it from the ingestion angle, which in reality the amount of ricin she drank may not be enough to kill her. But like the meth, liberties were taken. It was introduced as a highly lethal poison for ingestion. And the Breaking Bad ricin kills without a cure. More confusing realism with art. You guys are bummers.
