Don't eat this berry. But know this... It is mighty tasty.
I tried a few of these Red Elderberries two days ago, waited a while, felt fine, and proceeded to snack on them all day. Nothing happened to me, but I found later that they are technically poisonous, causing upset stomach and diarrhea. It's a good thing I found out before I went kayaking last night, because the island I camped on was full of these and I am sure I would have spent the whole night gorging myself.
I did read that they are OK once cooked, so I have made jam with the remaining harvest. If I don't post here for a while somebody call 911.
Yes, those are the berries I told you about here too. They look so enticing - but I was not man enough to taste of them.
Do tell if the jam turns out well.
