Like blackcurrant, elderberry is a natural anti-viral that shows promise in protecting against both seasonal and H1N1 swine influenza. Elderberry anthocyanins have been found to bind to H1N1 and block the ability of the virus to infect host cells. Researchers have favorably compared its activity to that of oseltamivir (Tamiflu®).1 A randomized, double-blind, placebo-controlled study on a standardized elderberry product found that it reduced the duration of the flu symptoms to just 3-4 days.2 The study also showed it to be effective against 10 different strains of influenza. Elderberry also reduces lipid peroxides, neutralizes lipid peroxyl radicals, inhibits LDL oxidation3, and offers significant protection to endothelial cells against oxidative stress.4
