About the book:

Natural Cures is poorly sourced and peppered with jaw-dropping absurdities, such as "The sun does not cause cancer. Sun block has been shown to cause cancer" or "All over-the-counter nonprescription drugs and prescription drugs CAUSE illness and disease."

This 600-page medical advice book contains no index, no bibliography and no references. In their stead are testimonials for the audio edition and a sequel in the works about "weight loss secrets they don't want you to know about."
- Scientific American

Although the infomercial suggests that the book makes specific recommendations for specific problems, it actually does not.

About the author:

Even before hitting the bestseller list, Trudeau, who is in his early 40s, had built a billion-dollar empire as a prolific infomercialteer, selling various health and self-improvement products under the cover of night. This despite a two-year stint in federal prison in the early '90s after pleading guilty to credit card fraud, and a 1996 tangle with the Illinois attorney general, who accused him of running a pyramid scheme while working for a health-products company called Nutrition for Life.

In 1998, Kevin Trudeau signed an FTC consent agreement under which he agreed to pay $500,000 and to refrain from making unsubstantiated claims for any product or program he advertises, promote, sells, or distributes in the future.

Trudeau cannot make disease or health benefits claims for any type of product, service, or program in any advertising, including print, radio, Internet, television, and direct mail solicitations, regardless of the format and duration. Trudeau agreed to these prohibitions and to pay the FTC $2 million to settle charges that he falsely claimed that a coral calcium product can cure cancer and other serious diseases and that a purported analgesic called Biotape can permanently cure or relieve severe pain.
