Diet Pill Fillers

I read an article that said some of the diet pills use fillers that are natural herbs and spices and they do not have to disclose what they are. But I thought anything you ate was supposed to be overseen by FDA .

OK some of the fillers are not drugs, but they do go in your mouth so it must be considered a food product Yes? ... No ? On one hand I think that the Food and Drug Administration should look into natural products, and on the other hand if they did more in that area, then natural products would cost more probably.

Most drug are derived from "natural" things to begin with. Like isn't aspirin from the bark of a tree or something? I do not know why people think if something is all natural that it is automatically safe? I always research supplements or vitamins before I take them, but I guess that is just me.

What do you think about labels not having to disclose ingredients?
