I did some checking and from what I read what you say seems to be true. However, we have to remember that there was not much known at that time and that's how doctors learned - thru trial and error. This still goes on today whether it be an operation, chemo, radiation, etc. Works for some and not for others.

Human trials today seem to help weed out some of the mistakes. As we know, there are many trials going on for all kinds of disorders.

The Mayo Clinic today is one of the top notch places to go when you have medical disorders that can't be totally helped in your local community. This is true of the Mayo Clinic in Rochester, MN.
