> Onion and garlic are extremely potent medicines. They are not food.

Sorry, what? Onion is one of the oldest cultivated plant and it's consumption exists in nearly every culture, in much "cleaner" times than today. If our guts can adapt to milk, it will have adapted to onion.

Also, you're going to have to show me evidence that the extremely potent medicine has extremely potent effects - what do we currently cure with onion? And please no big pharma arguments - aspirin and penicillin are still wildly available and they come from natural elements.
