Natural herbs and vitamins can be harmful. This is common sense for most people, knowing the dangers of burning poison ivy, although this has been overridden by vast marketing about the wonders of all natural sprite or how all our health problems can be cured by eating organic pizza. [pro tip: that won't work. greasy pizza made from organic cheese and organic pork may be yummy, but it's still greasy pizza]

The whole 'we have real sugar in our food' marketing going on is an example of this. Sugar is sugar, whether it's made from corn or beets. You can be healthier by eating less sugar,yes, but beet sugar is still sugar.

A lot of the natural trend is just hype, not hope.
