Olaeander

This eye catching evergreen shrub was given to me by a friend (she had been given it, but didn't want it) and I rather like it's exotic look and pretty pink flowers.
I just 'googled it' and have found out it is used as a poison!!
Do you think that friend was trying to tell me something???!!!    OR was the friend that gave it to MY friend trying to tell HER something?!
All a bit sinister!
