Ingestion of properly prepared CS does not result in silver accumulating in the body.
There is no evidence that silver deposits significantly in hair or fingernails and, in fact,
the data support the conclusion that after taking more than 2 mg of CS per day for several
months, silver seems to be purged from the body (mostly through urine) at about the
same rate at which it is consumed. Furthermore, upon terminating CS intake, it appears
that as much as half the silver residing in body tissue will be purged (through urine and
feces, but more and more through feces as time goes on) in less than a month. Even this
relatively short residence time could be reduced substantially if several liters of water
were consumed daily.
