There are a number of chemicals that are effective developers.  Caffeine
is just one of them.  I think tannic acid may be another one.  It is
hard to say what other chemicals may be in your food, or vitamins, that
could be an effective developer.

Without doing a biopsy, I am not sure one can be sure.  But since there
appears to be no bad effects from taking CS, does it matter.  As far as
I am concerned, it would be great if silver were to remain in the
tissues for ever, and protect me against diseases as long as it causes
no problems.

I have been watching for years. I have never run across a case of any
silver toxicity to a mammal, and no one has been able to produce one
when asked.
