Seeing the bit about black pollen reminded me of this. Earlier this spring I noticed lots of bright red pollen coming in, and I tracked it to several massive poison ivy vines in the fencerows. I'm not concerned with the oils from the leaves being in the honey, but here's my question/thought. Would eating that pollen help to stimulate immunity from said evil plant? I don't get rashes, so I wouldn't be a good test subject, and so far no one has been willing to volunteer. Any takers? My wife says no.
