A hereditary defect prevents the human body from synthesizing a natural cure-all made by most animals and found in abundance by primal man. This substance — made in the liver — protected him from an overwhelming list of health challenges that, until recently, were rare causes of death. Due to a genetic error of metabolism, the vast majority of us no longer produce this panacea, making us increasingly susceptible to costly, unpleasant, and often fatal maladies.

Thousands of scientific studies show that sufficient quantities of this substance in the bloodstream still provide the same protective properties. Thomas E. Levy, MD, JD cites more than a thousand of these published reports as he relates the history and science of the "primal panacea” and shares simple, powerful ways to raise your blood levels to those once enjoyed by our ancient ancestors.
