Why does the FDA seem so afraid of natural remedies?

They always seem to downplay anything natural. As if there is no way it could possibly work. They say there is no scientific evidence but yet they also say that certain products have not been evaluated by the FDA. So answer this: How do they know that there is no scientific evidence if the product has not been evaluated? And yet these harmful drugs are advertised on TV as if we have to take them or something! You cannot watch a football game without someone telling you how to enlarge you penis! "Take this for Herpies!" I don’t have herpies! Then they say it doesn’t cure herpies! well what does it do? "Side effects may include sudden death!"
Regina Wrong answer! The Japanese and Chinese live longer than we do and they base alot of their medications on herbs ect. We won’t even test to see if they work! Did you ever think about surgery? I mean it did not exist back then either! Thats hogwash I don’t think your answer explains Jack! FDA=$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
