If you've ever grown your own potatoes, when you come to harvest them you might find the odd one or two poking through the soil that have been sun exposed and thus green. Apparently you're not supposed to eat them. I just peel the skin off them and eat them anyway. No issues. As for eating them raw, I'm not sure why you'd want to. My mother always ate a chunk of raw potato when she was chopping them, to no ill effect. I've tried it, but it's not tasty like a piece of raw carrot or turnip.

I'm really not understanding this whole "poisonous potato" thing. As far as I'm concerned you just boil, roast or fry the damn things and eat them with skin on or off.

Maybe they're poisonous the same way alcohol, nicotine and caffeine are considered poisons. I think you'll find every vegetable is poisonous to some degree.
