I am curious I did ingest black nightshade ( thinking the green ones would ripen on the shelf like tomatoes) . They did seem bitter though and I got a mild stomach ache. Never do this I had been eating the black ripened naturally ones ;they tasted good lol no effect. ( I thought) Maybe ate over a few weeks several at a time maybe once or twice a week, like a few yrs.ago. So later… I have chronic anemia ( no cause as of yet known) . You with what you said probably don’t think this is connected, but I wonder.
