Rating (out of 5): 2

Elderberry (Sambucus nigra) has a long history of traditional use in treating upper respiratory ailments, including sinus infections. Folk medicine across Europe and North America employed elderberry preparations—such as teas, syrups, and lozenges—to help relieve symptoms like nasal congestion, sinus pressure, and inflammation. The rationale behind its use is based on elderberry’s purported anti-inflammatory and immune-boosting properties. Some historical texts reference elderberry as a “sinus cleanser” and remedy for catarrh (excessive mucus).

Modern scientific studies on elderberry primarily focus on its effects against influenza and the common cold, with limited direct evidence for sinus infections (sinusitis). A handful of in vitro studies suggest elderberry extracts may inhibit certain pathogens and reduce inflammation, theoretically benefiting sinus health. However, clinical trials involving sinus infection specifically are lacking. Most available research does not differentiate between sinusitis and general upper respiratory infections, which limits the strength of the evidence for this specific use.

In summary, the use of elderberry for sinus infections is primarily justified by traditional use. Scientific validation for its effectiveness in treating sinus infections remains limited and indirect, resulting in a modest evidence rating.
