These days, herbal diet pills are a popular alternative to a more traditional approach to weight loss such as diet and exercise. Herbal ‘remedies’ in general are all the rage today, which I find somewhat troublesome for a few reasons.
First, almost anything can be called an herbal diet pill. Herbs enjoy a kind of loophole in the FDA system because they are not classified as drugs and therefore don't have the strict standards for testing and safety that drugs get. In fact, herbs can be every bit as potent and potentially harmful as drugs. The difference between medicinal herbs and drugs is really quite vague anyway, as most FDA approved drugs start out as a particular plant or herb.
