Synopsis

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

Sambucus nigra (elderberry) has a long history of use in traditional medicine for the treatment of respiratory ailments, including congestion. In recent years, scientific interest has grown regarding its potential efficacy. Elderberry contains bioactive compounds such as flavonoids (notably anthocyanins), which are believed to have anti-inflammatory and antiviral properties. Several in vitro studies have demonstrated that elderberry extracts can inhibit the replication of common respiratory viruses (e.g., influenza), which may help reduce symptoms associated with respiratory tract infections.

Clinical studies on elderberry’s effect on congestion are limited but promising. A few randomized controlled trials suggest that elderberry extracts may reduce the duration and severity of cold and influenza symptoms, including nasal congestion, when taken at the onset of symptoms. However, these studies often involve small sample sizes and sometimes use combination products, making it difficult to attribute effects specifically to elderberry. There is insufficient evidence from large-scale, high-quality trials to firmly establish elderberry as an effective treatment for congestion, but preliminary data indicate some benefit.

Overall, while elderberry has a strong traditional usage background for congestion and some scientific research supports its potential, the evidence is currently moderate and further research is needed to confirm its efficacy specifically for this symptom.
