Dr. Clark has done brilliant and courageous work with this book!!! She has exposed what many doctors and researchers are only just now beginning to discover – that every disease has a parasite involved with it. And that pollutants are also involved in diseases. These pollutants come from simple things such as breakfast cereals! I have had personal experience of the GREAT benefits of following her advice. The herbal parasite program greatly decreased my appetite. The zapper heals me if ever I get the flu within an hour or two!
