A study comparing the anti-microbial effectiveness of a water-based preparation of echinacea purpura to that of an ethanol-based preparation on the vitro growth of candida albicans and escherichia coli

Abstract

The purpose of this study was to compare the effect of a water-based extraction of Echinacea purpura (E. purpura) on the in vitro growth of Candida albicans (C. albicans) and Escherichia coli (E. coli) to a control of distilled water in terms of the size of the zones of inhibition. It also sought to compare the results to those obtained from experiments using ethanol-based tinctures of Echinacea purpura
