Xylitol (Silicon Dioxide) has the ability to selectively inhibit the growth of pathogenic microorganisms without affecting the normal vaginal flora. It can reduce the growth of Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguis and some strains of Escherichia coli, Saccharomyces cerevisae and Salmonella typh. Xylitol blocks the binding of bacteria to host cells, preventing them from multiplying. The amount of Xylitol contained has the role of inactivating, but does not necessarily kill the pathogenic microorganisms responsible for vaginal infection, does not significantly affect or inhibit the growth characteristics of normal vaginal flora, has no irritating action on the vaginal mucosa.
Silicon dioxide, used as a stabilizing agent in the contents of Halova is an inert ingredient, which means that it does not interfere with other active ingredients in other supplements or medicines and thus minimizes the risk of developing antimicrobial resistance.
