From the primitivetechnology guy I heard the same. He also gives another tip, similar to part of ritual from the article:
A lot of toxic plants can be washed with clean flowing water for a few days. Chop them up and put them with a net in a clean natural stream if available for three days or so. Test the end result for the same way you would do with other unknown edibles (armpit, lips, etc).
One could probably try all the mentioned ritual techniques.
