I would be interested in comments from anyone who feels they have good scientific (whatever that may mean) grounds for believing that colloidal silver or other silver compounds are useful in any aspect of human health, and what these areas are and why they think them valid. People who think otherwise are of course free to comment *BUT* there is any amount of "anti" material available (and understandably so) and I'm more interested in 'leads' which are *potentially *positive. _______________________________ I'm (hopefully) about to do some playing with colloidal silver with a specific medical aim in mind. *This is an area utterly awash with charlattans, snake oil sellers, the odd over unity pusher and many more. * It also seems that CS does actually "work" in specific situations. There are substantial numbers of studies and peer reviewed papers on the subject which, it seems, increasingly come down on the plus side of the ledger. Particle size and even shape seems to matter. I suspected that somebody would have found out that use with nano-titanium-dioxide would be especially effective, and lo, it verily is so, with peer reviewed papers following in support. and, for many years, colloidal silver has been used in fired-clay water-filters / containers to provide disinfection AND residual disinfection of otherwise contaminated water, and good stats are available on efficacy. You know you are in trouble when the proper end product is clear and if you make coloured stuff its bad and you detect the good stuff by shining a LASER beam through the good solution *BUT* that is indeed how "it works, and there are good "scientific" reasons for it. You know you are in trouble when the proper generators have to use constant current and the ones that use constant or unregulated voltage are no good - obvious quackery *BUT* that is indeed how "it works" and there are good "scientific" reasons for it. Interestingly, there were a few published papers in the early post 2000 period which determined that CS was completely ineffective. Since then a significant number of published papers have concluded otherwise , but certainly not all .. Maybe it gets stronger as we enter the house of .... :-).

Colloidal silver as an antimicrobial agent: fact or fiction? Conclusion: As the tested colloidal silver solutions did not show any antimicrobial effect in vitro on the microorganisms, claims of colloidal silver's antimicrobial potency are misleading and there is no place for it as an antiseptic. ______________________ These relate to silver generally - often as AgNO3. Note that results can be organism and perhaps environment specific.

Controlled trials showed the outstanding prophylactic value of 0.5 % silver nitrate compresses applied to burns, and significant, though smaller, effects of a cream containing 0.5 % silver nitrate. The greatest effect was against Ps. aeruginosa and Proteus spp.; a trial in patients with extensive burns showed Ps. aeruginosa in 70% of swabs from the control series (treated with penicillin cream), but in only 3.1% of swabs from the series treated with silver nitrate compresses. ... .... *There was less prophylactic effect against Staph. aureus and none against certain coliform bacilli. * Treatment with silver nitrate applications was associated with lower mean temperature and respiration rates, and other clinical advantages. No toxic effects attributable to silver nitrate were detected, and the applications, though uncomfortable, were not painful. 1999. It doesn't. http://www.ncbi.nlm.nih.gov/pubmed/10384851 2009.
