Elderberry for Sinus And Congestion Relief

The two studies provided do not contain research on elderberry for sinus or congestion relief. Both studies focus on COVID-19 related topics, specifically long-term smell and taste dysfunction following COVID-19 infection and vaccine effectiveness against the Omicron variant in a congregate setting, and neither investigates elderberry as an intervention. As a result, no evidence-based summary connecting elderberry to sinus or congestion relief can be drawn from this literature. Readers interested in this topic may wish to seek out studies that directly examine elderberry supplementation and upper respiratory or sinonasal outcomes.
