Regarding the comment about "snake oil", it's still flowing freely. Take a good look at the ads for most of the homeopathic, natural remedies being touted today.
Unfortunately, Congress was bought off by the so-called natural health industry and even the wildest claims can be made without any scientific proof.
(I won't comment on the vast amount of inaccurate information spread on the net.)
