Divaricatic acid has antibacterial properties against some Gram positive bacteria, such as Bacillus subtilis, Staphylococcus epidermidis, Streptococcus mutans, and Enterococcus faecium.^[5] Since it also has activity against methicillin-resistant Staphylococcus aureus (MRSA) with a potency equivalent to that of vancomycin, it has been suggested as a potential treatment for MRSA.^[5] It also has molluscicidal activity against Biomphalaria glabrata (ram's horn snail) and antiparasitic activity against cercariae of Schistosoma mansoni (blood fluke).^[6]
