The Clark and Christopher herbs for the kidneys are basically the same, only Dr. Clark suggest a 6 week treatment twice per year. Dr. Christopher would have you care for your kidneys every day of your life.
Dr. Clark made very wrong statements for her book titles that made her famous, people want to buy her products and do her methods in search of that cure she talks about. People don't care much about Christopher anymore, he has been dead too long and about forgotten. Christopher did know how to heal, Clark is too caugth up in science and in the long run, all her synthetic supplements causes cancer in my opinion. Her book titles made her famous, even the curezone holds her in high esteme, few realize her methods will end in cancer for the victims of her books.Her methods create an acid body and destroys the red blood cells.
