Black elderberry, derived from the Sambucus nigra plant, has a long history of traditional use and a growing body of modern research exploring its potential health benefits. Studies indicate that elderberry contains a rich concentration of anthocyanins and flavonoids, which contribute to its notable antioxidant activity. Research suggests that elderberry supplementation may help reduce the duration and severity of cold and flu symptoms when taken at the onset of illness, possibly by supporting the body's natural immune response. Some preliminary evidence also points to its potential role in easing sinus congestion and upper respiratory discomfort. Commonly available as syrups, lozenges, and gummies, black elderberry remains one of the more widely studied herbal options in the immune support category, though researchers continue to investigate the full scope of its effects.
