Synopsis

Source of validity: Traditional
Rating (out of 5): 2

European Elder (Sambucus nigra) has a long history of traditional use in Europe and other regions for the treatment of respiratory ailments, including lung congestion, colds, and flu. The flowers and berries are the primary parts used, often prepared as teas, syrups, or tinctures. Historical herbal texts, such as those by Culpeper and Gerard, document the use of elderflower infusions to promote sweating and help "break up" chest congestion. The presumed mechanisms are attributed to mild expectorant and diaphoretic properties.

Although modern research has explored the antiviral and immune-modulating effects of elderberry, particularly in the context of influenza, there is limited direct clinical evidence specifically linking elderberry or elderflower preparations to relief of lung congestion. Some in vitro and animal studies suggest that compounds in elderberry may reduce inflammation and mucus production, but these findings have not been robustly confirmed in human trials for respiratory congestion. Overall, while traditional use is well-documented and some preliminary scientific rationale exists, high-quality clinical evidence remains lacking, resulting in a modest evidence rating.
