Rating (out of 5): 2

Elderberry (Sambucus nigra) has a long history of use in traditional herbal medicine, particularly in Europe and North America, for the treatment of respiratory ailments such as congestion, colds, and flu. Traditionally, elderberry preparations—including syrups, teas, and lozenges—have been used to help relieve symptoms of upper respiratory tract infections, which often include nasal and sinus congestion. Folk medicine practitioners have valued elderberry for its purported ability to reduce mucus and promote sweating, both of which were believed to help "clear" congestion.

From a scientific perspective, some laboratory and clinical studies have suggested that elderberry extracts may have antiviral properties, especially against influenza viruses, and may help reduce the duration and severity of cold and flu symptoms. However, evidence specifically focusing on nasal or sinus congestion is limited. Most clinical trials have assessed elderberry's effect on overall respiratory symptom scores, not congestion alone. While some users report subjective improvement in congestion, robust scientific evidence confirming this specific benefit is lacking.

In summary, the use of elderberry for congestion is primarily based on traditional use rather than strong scientific validation. More high-quality, targeted research is needed to determine its efficacy for this particular symptom.
