Sambucus nigra (elderberry) has a long history of traditional use for respiratory ailments, including congestion of the lungs. Its use can be traced back to European folk medicine, where elderberry preparations—such as teas, syrups, and tinctures—were commonly administered to help ease symptoms of colds, flu, and upper respiratory tract infections. The berries and flowers are thought to contain compounds with anti-inflammatory and diaphoretic (sweat-inducing) effects, which could, in theory, help alleviate congestion by reducing inflammation and promoting the clearance of mucus.

While in vitro and some animal studies have suggested that elderberry extracts possess antiviral and immunomodulatory properties, direct scientific evidence supporting its effectiveness specifically for lung congestion is limited and inconclusive. Most available clinical studies focus on elderberry’s potential to reduce the duration or severity of flu-like symptoms rather than addressing lung congestion as an isolated symptom. As such, the use of Sambucus nigra for lung congestion primarily rests on its traditional role in herbal medicine rather than robust clinical validation.

In summary, while there is a well-established historical precedent for using elderberry to support respiratory health and potentially improve congestion, strong scientific evidence supporting this specific use is lacking.
