It's on the Internet, so it must be true.
It's amazing the number of quack remedies that are out there. The days of snake oil are still alive and well, as is human nature. Sadly, as the site you linked to points out, there are a lot of people willing to believe rubbish.
Remember Zerret water from the 1950's?. You had to hold the container in both hands, making sure all your fingers were in contact with it and that your legs were uncrossed. This was done three times a day for 15 minutes and would help arthritis, rheumatism, diarrhea, constipation, excess weight and abnormal thinness, as well as a variety of other conditions. There were people that swore that it worked, but needless to say it didn't.
Human nature really hasn't changed much in the last 60 years.
