    ABSTRACT

    We endeavour to resolve some of the confusion surrounding the (mis) use of the term ‘colloidal silver’, particularly in a pharmaceutical context. It is proposed that, wherever possible, the term ‘colloidal silver’ be replaced by a clearer descriptor indicating a silver formulation’s composition and function, particularly when used either to help treat infections and/or to stimulate healing (as in restorative medicine).

    For discussion, we propose adopting some less ambiguous terms to describe metallic silver formulations; this new terminology being more related to their physical properties and their end use, e.g. bioactive silver dispersion, nano (sized)silver clusters (NSC), reactive atomic clusters, ‘quantum meta-silver’, etc. Methods for characterising medicinal silver products are also considered – these being needed to adequately certify the chemical composition and physical properties of novel pharmaco-active silver formulations – before submitting them for clinical evaluation.

    Key words: Materia medica, Silver antimicrobials, Nano silver clusters (NSC), ‘quantum silver’, ‘meta-silver’.
