Here is a book by a naturopathic doctor on naturopathic medicine which may help you understand it. It's easy reading with a lot of good advice for your general health. You'll never look at the medical industry the same way again...
"Everybody Is Sick And I know Why" by Peter J. Glidden, ND.
Incidentally, Dr. Joel Wallach (author, "Dead Doctors Don't Lie") is a Naturopathic Doctor as well as a world class veterinarian (he wrote many of their medical reference books). But he was blackballed from that career by the CDC because he went against CDC dogma on cystic fibrosis (he proved them wrong!) even though he was employed in a very responsible position by them. He tells the story in his book. Fascinating reading.
Thank you, Gritty. It’s good to add you and Steve Van Doorn to the list of people who are very knowledgeable about natural healing. Thank you for the reference. I will try to find a copy and read it as soon as I can.
