Hi all,

The Materia Medica listing for Argentium Nitricum (Silver Nitrate) is correct 
according to
the latest Materia Medica Ninth Edition by Boericke & Tafel, Inc. is just what 
it says . . .
SYMPTOMS FOR OVERDOSE OF SILVER NITRATE.  This has absolutely no relationship 
to Colloidal Silver whatsoever!!!!!!!!!!!!!!!!  

The only persons in danger of ingesting too much Silver Nitrate in their 
Colloidal Silver are
those who carelessly make Colloidal Silver with HVAC - Open Arc, and allow the 
process
to run too long.  The EPA limit for Silver Nitrate ingestion by humans is set 
at 20 PPM.  When
Colloidal Silver made in this manner is allowed to run for an extended time, 
say 24 Hours or more,
you can generate a Silver Nitrate loading in the batch that might approach 70 
PPM.  Then, you
might possibly start getting symptoms described in the Materia Medica.

Independent laboratory testing has shown the following characteristics, in 
part, for a long running
batch using open arc, 12,000 VAC.

Hanna TDS 1 Meter Reading                    870 PPM               Actual by 
Lab                47.8 PPM
Nitrate test strips                                      60 PPM +            
Actual by Lab                68 PPM
Hanna PH Meter                                      2.7 PH                  
Actual by Lab                1.98 PH
Nitric Acid                                                                     
      Actual by Lab                >0.1 % (Was Below Test Capability)
Viscosity                                                                       
      Actual by Lab                1.208

This is typical of the testing being done for me by a certified laboratory on 
instruments within their 
certification or calibration dates.  In some cases the instruments are freshly 
calibrated for our tests.

This is the only way that I can see that a person could get these symptoms from 
using colloidal
silver.  Use of any substance by humans without comprehensive, continual 
testing is playing Russian roulette
with your well being!

The reason I have not presented this type of information before is that testing 
of CS is wildly variable in results
using the equipment that is affordable to most.

Questioning suppliers (Hanna, Cole-Parmer, and other suppliers of equipment) 
brings one result: you cannot
rely on Conductivity, TDS, Water Quality Instruments, ETC. to test Colloidal 
Silver - Period. You might be able
to get close if you have a competent lab do repeated tests versus your 
instrumentation until you develop a
correction factor.  For instance - up to 250 PPM on a Hanna DiST WP Meter, 
properly calibrated, AND:
properly cleaned after each use - - - you could divide the reading by eight (8) 
and have a reasonable approximation
of the strength of Colloidal Silver.

Example:  Lab test - 19.6 PPM        Hanna DiST WP  158 PPM        158/8 = 
19.75 PPM
