The curezone is like it was 20+ years ago--------so virtually all health subjects can be an open discussion....
today, the world is flooded with fake products-----I suggest the best books were written pre 1950's, most were from medical drs and some from herbal drs.....and yet, a few great drs existed in the past 30 years.
GOOD THING is the fact the books exist and people can teach them selves.
