Elderberry and Infections

As many of my patients are already well aware, I often rely upon Elderberry extract, especially in the treatment of influenza and other viral infections. This recent study demonstrates evidence as to why this treatment is effective.

In a study designed to examine the effects of a standardized extract of black elderberry (Sambucus nigra L.) on 3 Gram-positive bacteria and one Gram-negative bacteria responsible for upper respiratory tract infections, as well as two different strains of influenza virus, the extract was found to possess antimicrobial activity against both Gram-positive bacteria of Streptococcus pyogenes and group C and G Streptococci, the Gram-negative bacteria Branhamella catarrhalis, and human pathogenic influenza viruses. The results of this study suggest that elderberry extract such as the one used in this study may be an effective tool for helping to combat various types of upper respiratory tract infections.
