Hi all, I am in the Netherlands and found much the same as others: the advice is to call your GP if you suspect poisoning, and health professionals can call 088-7558000 for the Nationaal Vergiftigingen Informatie Centrum. They also have a list of side effects noted from certain plants (though most of these are not poisonous, more possible irritants) https://www.vergiftigingen.info/f?p=300:STOFMONOGRAFIE:11502670636932::::P1210_VERB_NO,P1210_FROM_PROD_NO,P1210_FROM_PRODSYN_NO,P1210_ROUTE:640,13681,1,BEREKEN_ZONDER_CASE
