The cycads, highly poisonous palm-like trees, are seen all over Okinawa. I had a vague recollection of islanders who were saved from starvation by learning to extract and cook the pulp of the plant. When eaten raw, it can cause internal bleeding, liver damage, and even death, but it had actually been the very means of saving many lives.
I remember seeing an Amami Oshima country maiden figurine made of cycad seed, showing the people's gratitude for how that plant had kept them alive.
Perhaps sometimes the things that seem the most toxic to us could be the very things God would use to save our lives.
(Actually, the figurine I saw was much cuter, but I can't find a photograph of it, so I'll have to draw one from memory, ok?)
