How does it work

Elderberry might affect the immune system. Elderberry seems to have activity against viruses including the flu, and might reduce inflammation. In many countries, including Germany, elder flower is used to treat colds and flu. Some evidence suggests that chemicals in elder flower and berries may help reduce swelling in mucous membranes, such as the sinuses, and help relieve nasal congestion. Elder may have antiinflammatory, antiviral, and anticancer properties.
