Silver colloid (Argentum colloidum)

Has antimicrobial, astringent, cauterizing properties. During dissociation, silver ions cause the precipitation of proteins and cause bactericidal action. Interacts with tissue proteins, which leads to the formation of silver albumin. Then metal silver is recovered from the albumin, which interacts with the active groups of the enzymes, blocks them, thereby disrupting the metabolic processes in the microbial cell. At small concentrations of silver ions, only the precipitation of interstitial proteins occurs and astringent and anti-inflammatory effects occur. In high concentrations, silver ions cause damage to cell membranes and intracellular structures, providing a cauterizing effect (friable albumins are formed).
