Elderberry

Elderberry, most commonly 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 is rich in anthocyanins and other polyphenols, which contribute to its notable antioxidant and anti-inflammatory properties. Research suggests that elderberry extract may help support immune function and could reduce the duration and severity of cold and flu symptoms when taken at the onset of illness, though results vary across studies. Some preliminary evidence also points to potential benefits for sinus and upper respiratory congestion relief. Elderberry is widely available as syrups, lozenges, and standardized extracts, making it one of the more accessible and well-studied herbal supplements in the immune support category.
