Hydrilla found in the Fountain of Youth?

I recently discovered this site from a link in the banner ads that appear at the top of the blog. It's an advertisement encouraging people to buy "Hydrilla Plus," a putative anti-aging herbal supplement. If you click here you'll see that the main ingredient in Hydrilla Plus is Hydrilla verticillata, the invasive, pervasive, aquatic plant that many have grown to hate. I would say the product is doing a great job, as evidenced by the photo of grey-haired Dr. Halvorson, father of seven children and currently over 250 years old! (just kidding)
