I'm generally very skeptical about these folks and their claims. I can't watch the clips from work, so I haven't seen them, but in looking at the website, it seem everyone is promoting their "amazing product". I try to keep an open mind, but double-blind testing and clinical trials are an important part of validating the effectiveness and safety of any "medication". Many of these folks rely on anecdotal evidence or a few people who claim to have been helped. Then they tell you that modern medicine doesn't want you to know about these remedies. Like I said, I try to keep an open mind, and I do use some herbal supplements, but I also spent a bit of time researching the ones I take and specifically looking for controlled experiments that tested their effects.
Ultimately, I guess that's my opinion, people need to do some research and if the only source of info are the folks who are selling these products, I'd procede with caution.
My 2 cents.

Tho' much is taken, much abides; and though we are not now that strength which in old days moved earth and heaven; that which we are, we are; one equal temper of heroic hearts, made weak by time and fate, but strong in will; to strive, to seek, to find, and not to yield.
