Hi,
I have read the article in nnfa journal.  I t dosent actually say anything
except that colloidal minerals often do not contain what they say.  Truth
is they dont. It also says that customers should demand an analysis and one
that states who did it and how.  We have product here direct from the Clark
mine and product here from several multi level companies in UTAH. m  None
of the claims can be matched by atomic spectrosopy measurement.  One large
company in UTAH says plus colloidal silver. There was no silver registered
by analysis.  We have phoned the Clark mine and been told "can they do
that, I think colloidal measurements are different" 
Yes I am aware of the FDA inaccuracies, inability to see value for people.
All the same fair is fair.  Big brother may have a point, crazed though he
looks on television.
Coming back to Wallach. He talks down many physicians by name, points out
truths about them that otherwise just get buried. From here it looks like
he is heading for FDA damage.  Wallach has many great points because he has
seen what minerals do all over the world for animals.  He knows that the
responses are much the same in humans.   We here are very much involved in
mineral analysis, soil reparation, body reparation. We see minerals as
important in nutrition over most other factors because without them in
balance all the vitamins we pour in are just wasted that is from bottles
and from food. 
Your mention of Argyria is presently being tested by us. The test is to
assume how long it takes and what silver level it takes.   Our feelings are
that silver levels for daily ingestion should be kept in the lower but
regular count.   Good distilled water is probably more important than
increasing the ppm level.  Minerals need to be built slowly ( that is in
the body) . Silver might be seen thus:
Blood < 0.003 mg dm-3  
Bone 0.01 - 0.44 ppm   
Liver 0.005 - 0.25 ppm
Muscle 0.009 - 0.28 ppm
Lungs 0.009- 0.32  ppm
Daily intake  0.0014 - 0.08 mg
Average minerals  (70 kg) person 2 mg 
They need to be established slowly in at different levels

Robert Beasley
