We have.

That must have been a while back, unless you know someone there, as
their new policy is that they don't talk to amateur botanists.

That is why I looked at the scientific papers. What is clear is
that it is quite safe under some conditions, and unsafe under others,
and there is no consensus on what those conditions are!

The main difference between it and common staples is that we tend
to know the conditions under which the latter can be eaten safely.
