Dear Cherie it depends what species of Euphorbia it is! Some have toxic roots and other it is the sap that can be harmful. It is not in Aconitums league scale, but it is something you should be aware of especially if dead heading it. The seeds can also be toxic, but that again depends on what species it is. Some are not at all none to be toxic.
In the UK we have a H.M.S.O. book that tells you all the toxic plants regarding livestock and for Horticulture! I have alsways had one of these as they are indispendsable to us! In the US I know you have DG Plant files that can tell you if it is Toxic but you also have Thousands of Databases that tell you everything form the symptomas to the cure!
That is assuming there is a cure. Why don't you ask me or your databases.
