I've seen article about great benefits of eating avocado seeds. And another here.
Does it mean avocado seeds are edible? How do you eat it then?
On Wikipedia page we can read:
Avocado leaves, bark, skin, or pit are documented to be harmful to animals; cats, dogs, cattle, goats, rabbits, rats, guinea pigs, birds, fish, and horses can be severely harmed or even killed when they consume them.
How about humans?
Somebody from here suggested that the avocado pit is mildly toxic.
