Nina,
Your concern is quite justifiable.  I have taken a magnifying glass to
one of the little bottles of the Biopur, and this is what it has to say:

FORMULA: Agua destilada, proteina y plata coloidal estable al 0,15%

Bye for now.

Thank you, Julie, for your willingness to post this again. I am not
questioning the efficacy of this product, only expressing my concern
about:

1) the manufacturer's lack of distinguishing between ionic and
particulate
silver, and lumping them both under "400 ppm"; and

2) the possibility of developing argyria from silver compounds. I would
want
to know more about what's in my product.

Thanks again.
Nina
