Hi Jim.

One quick way to find out (they are considered toxic by the feds) is to
call Poison Control in Halifax and ask what their database says. I will
do [have done?] just that:

R. cathartica
R. frangula

Contains anthraquinones causing GI [gastro-intestinal tract]: nausea,
dizziness, abdominal pain, vomiting, drastic cathartic that can be fatal.

Can cause kidney damage.

20 berries of either species is enough to produce symptoms.
