Had some indirect experience with this tree in a place called manchoneel bay, off Cooper Island, BVI. The things are all over the hillsides. We were having lunch at the Beach Club when someone on one of the nearby moored sailboats was having a manchoneel “attack”. The place was swarmed with Virgin Island Search and Rescue who hauled the person(s?) away at high speed. Our waitress said it happens a couple times a year. Never heard how it turned out for them.
Probably should put a statue on the ground there, showing a dying guy holding one of the fruits with a bite taken out of it. That would require no multilingual caption. :^)
I went there on the SV Flying Cloud for my honeymoon 25 years ago.
Back when Windjammer Barefoot Cruises was still in business.
That was one of the things they told us. Do not touch the trees, fruit, etc.
We spent most of the time in the water.
I remember meeting the guy who owned the island. He had inherited it from his dad. His great great grandfather had been a slave on the sugar cane plantation there.
