I told them about it, but they dismissed Oleander as a poison! It may sink in, they are researching alternative cures, if they ask me for any more advice I will remind them and give them further info.
You know what they say, you can drag a a horse to water etc. Been down this road before, will just let them decide. If anything ever happened to me, I would make my own decisions, and thoroughly research every possibility from as many sources as I can find.
