Are all milky saps equally dangerous?
We have one thread already discussing the dangers of the milky sap that comes from Euphorbias, but what about the other plants that also have milky sap? (i.e. Asclepias, Amsonia, poppies, etc.) Are they all equally dangerous or is there some caustic substance that is unique to the Euphobia sap that is not in the other milky sap plants? I'm starting some different varieties of Asclepias this year so that's why I'm concerned. (I also already have two large Amsonia plants though I've never used them as cut flowers.) According to Wikipedia this type of sap is actually termed latex. ( http://en.wikipedia.org/wiki/Latex#Sources ) Perhaps Euphorbia marginata has been more of a focus for concern simply because it's more widely grown for cutting than the others?
