Buckeye is poisonous!! The seeds and all other parts of the buckeye tree are highly poisonous to humans and livestock if ingested, although squirrels are known to eat the raw seeds. Native Americans historically used the seeds as a food source after boiling and leaching them to remove toxins. Folklore: Buckeye seeds are popularly carried as good luck charms.
