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

Sambucus nigra (elderberry) has a long history of traditional use for treating symptoms of upper respiratory tract infections, including sinus congestion. Folk medicine in Europe has employed elderberry preparations—such as teas, syrups, and tinctures—to help relieve colds, sinusitis, and flu-like symptoms. The rationale behind its traditional use lies in its purported ability to promote sweating and its mild anti-inflammatory and antiviral properties, which are believed to help clear congestion and soothe irritated mucous membranes.

However, scientific evidence specifically supporting elderberry’s efficacy for sinus congestion is limited. Most modern research focuses on its potential to reduce the duration and severity of influenza and common cold symptoms, not sinus congestion per se. Several small clinical trials and laboratory studies suggest elderberry extracts may reduce upper respiratory symptoms, but these studies typically assess general cold symptoms rather than targeting sinus congestion directly. The bioactive compounds in elderberry, such as flavonoids and anthocyanins, may have mild anti-inflammatory effects, which could theoretically help with congestion, but robust clinical evidence is lacking.

In summary, while Sambucus nigra is widely used in traditional medicine for sinus congestion and related ailments, scientific validation for this specific indication remains limited. The evidence is primarily traditional, with a modest (2/5) rating due to the lack of targeted clinical studies.
