I've never been to a Whole Foods store so perhaps the joke is lost on me but isn't the whole point of eating whole foods, escaping the potential yet unknown "magic" combinations that occur with food processing?
I'd be more inclined to call it 5% of the floor space at most, but maybe there are differences between stores.
Have you ever used Arnica gel on a bruise? Oscillococcinum for a flu? Extremely effective naturally derived products.
There are other types of non-standard remedies, which you might be talking about. But Homeopathic, specifically, is a synonym for water with fancy labeling.
So, quack quack?

That's true, it's not science at all, but homeopathy is a particular form of quackery (and many homeopathic products are frauds on top of the quackery of homeopathy.)
