Ginkgo

Notes:

The green leaf is edible (yellow not yet confirmed). The female Ginkgo produces fruit/seeds which are also edible (pulp and nut). Make sure you cook ginkgo nuts before eating them, since they contain a compound that can block vitamin B-6 in your system that can only be deactivated by boiling. The flesh of the fruit can also cause a reaction in some sensitive people. Personally, I would avoid the fruit unless it was a survival situation. Second, I'd recommend everyone to do their own research on this- if they were to consume from this tree.
