Tom,

> Raw rhubarb and kidney beans are toxic;

I ate them more then once and enjoyed them a lot, the same I did with potatoes,
without any bad effects. The problem is, that many people don't know about the
instinctive stop and instinctive attraction. Any food can be poisonous if you eat
it against your instinct. And even 'toxic' food can help in certain
circumstances, like medicine.
