Elderberry (Sambucus nigra) has a long history of use in traditional herbal medicine for a variety of ailments, including those involving congestion. While most modern attention focuses on its applications for cold and flu symptoms, in traditional European and Native American medicine, elderberry preparations (such as syrups, teas, and tinctures) were also used to "move fluids" and "open blockages," concepts that often encompassed lymphatic congestion. Herbalists have historically described elderberry as a "blood purifier" and a "depurative," terms that suggest it was thought to aid in the clearing of internal toxins and support the movement of lymphatic fluid. However, while folklore supports its use for this purpose, there is little direct scientific research validating elderberry’s effects on lymphatic congestion specifically. Most studies on elderberry address its antiviral and immune-modulating properties, not its impact on the lymphatic system. Therefore, while the use of elderberry for lymphatic congestion is justified by traditional herbal practice, robust clinical evidence is lacking, and its use for this purpose should be considered as complementary and not primary treatment. Those interested in elderberry for lymphatic issues should consult with a qualified healthcare provider, particularly if symptoms are persistent or severe.
