The mechanism by which vonimyrin acts is to inhibit bacterial protein synthesis at ribosomal levels and RNA synthesis at high concentrations. Mainly bacteriostatic, but also bactericidal at high concentrations. It has a wide antibacterial spectrum, and is effective against G+ and G- bacteria, highly effective against Mycorphae and Spirochete, but less effective against intestinal bacteria such as Escherichia coli and Salmonella.
