    I'm wondering has any scientific tests/studies been carried out on colloidals, that prove or disprove their use in medicine?
    Is there any good books on the subject....

    a quick google shows a hit on http://www.quackwatch.com/01QuackeryRelatedTopics/PhonyAds/silverad.html :(

    and this on wikipedia http://en.wikipedia.org/wiki/Medical_uses_of_silver
    lots of ref's at the bottom - look for the ones starting with DOI: or where the site ends with .gov especially .fda.gov , .nih.gov


    Silver can be used as an external antibiotic. It can be used in tiny amounts to keep pure water safe. And by tiny you are talking about the amount of silver that dissolves in water. It's not suitable for internal use.

    Think of it like bleach.
    It kills bacteria. Our water supply has chlorine in to kill bacteria. Milton is a bleach used to sterialise babies bottles. (bleach breaks down to salt BTW)
    But no one in their right mind would recommend you drinking bleach.


    If it's not available in your local chemist then it's probably not safe and/or not effective.

    It makes you turn blue, doesn't it? Can't be good.

    The jury is still out on teh use of colloid gold injections for the treatment of arthritis. I think it's ineffective in enough cases to not bother considering it tbh.

    Why can it be used to keep pure water safe to drink? it is taken orally in this way

    Why is is not deemed suitable for internal use when the amount of silver used is so small (5ppm to 500ppm), would the body not dispose of it naturally. Do we not take in alsorts of toxins in different amounts that the body rids of via the liver and kidneys?

    Tiny silver particles would be treated different by the body. They can't be chemically treated for easy removal (the way some compounds get reduced or hydroxylated etc), and as they dont have antigenic sites onthem, they can't be caputred by antibodies for removal.

    TBH it's a concern for many nanoparticles, there's a lot of research ensuring toxicity wont be a problem when we go to use nanoparticles for diagnostics and medicine.
