Elderberry is used to fight infections, influenza, coughs, bronchitis and other respiratory complaints. It also inhibits replication of several strains of influenza viruses A and B. It is rich in bioflavonoids and anthocyanins - two very potent immune-enhancing antioxidants.  In vitro, elderberry has been shown to inhibit H1N1 flu (aka swine flu). If you have a predisposition to coughing, elderberry is for you!
