However, when I look at the FDA's website, I don't find any regulations like this for bloggers. I do see the FDA has all the rules I mentioned above for those who are selling herbal supplements. Therefore, I suspect the FDA is mostly concerned about bloggers who are making money (no matter how little) through affiliate links for natural medicine.
That said, I'm no lawyer, and many bloggers disagree with my conclusions. Indeed, given the fact that the FDA has been going after herbalists and other alternative practitioners, many of my fellow bloggers are convinced the FDA is trying, little by little, to make it impossible for consumers to learn about and use natural remedies.
I don't have the means to hire an attorney to figure this out, and the FDA doesn't seem to want to make this clear for bloggers. So I'm going to assume that if I'm just recommending something to you as a friend - not as someone who will earn anything off a sale - the FDA will leave me alone.
I didn't go into blogging to become rich. I blog because I want to help people. So I'm going to continue to recommend natural medicines I believe (often from personal experience) work. I just won't be earning pennies if you click on a link and buy a natural medicine.
