Dr. Christopher was a fan and friend of Mr. Klaus. I personally read the book and then never read it again or refer to it. It is OK, but not as easy to use as the Christopher books and I also am not so keen on the consumption of beans in general, no more than the consumption of grains that Dr. Christopher preaches. Dr. Christopher mentions Dr. Shook more than any other teacher he had and to this point I have never came accross a Dr. Shook book to read.
Today the soybean is probably made into more products than any other herb.
