                                The mature tamanu fruit, from the tree *Calophyllum inophyllum*, is definitively poisonous and should not be consumed, with some historical references even suggesting its use as rat bait. For anyone considering this tropical botanical for their nutrition diet, it is crucial to understand the vast and dangerous difference between the toxic fruit and its highly regarded, externally-applied oil.
