People ask me questions about mercury toxicity all the time. I’ve spent over ten years researching and writing about the mercury-based preservative Thimerosal, which is detailed in my book, Thimerosal: Let The Science Speak. The preface to the book is written by Mark Hyman, M.D., one of the best known and most respected physicians in the country, and the introduction is by Harvard University neurologist Martha Herbert, M.D./Ph.D. Dr. Hyman and Dr. Herbert are just two of a team of the nation’s most outstanding researchers and clinicians who have helped me gather scientific data on Thimerosal.
