Someone should create a product called "Snake Oil". It would make millions. There'd be no shortage of testimonials. A doctor or two would recommend it. Or how about a product called "Placebo". It has an exotic sound to it. And people really go for the "herbal" products that sound somehow scientific. The name rolls off the tongue nicely, too. Throw in the words "god send" and "miracle", use a voice actor who sounds confident and friendly, and your radio ad will sell millions. "Buy Placebo today: it's clinically proven to make you feel great!"
