I know the seeds are mildly poisonous, but what about the leaves? What about the leaves of other trees like, orange trees, plum trees, maple trees, ground banana tree leaves, etc? If the bark of a tree is edible, does that imply that it's leaves, seeds, and sap are edible as well? Vice versa? There are also some foods that are somewhat toxic, such as acorns, but they are better when prepared a certain way. Certainly there are many perfectly edible plant parts, such as kiwi skins, that are ordinarily disposed of. Can anyone comment on this topic?
