Elderberry refers to the small, dark purple berries produced by the Sambucus plant, commonly found in Europe and North America. These berries grow in clusters and are known for their rich antioxidant content, particularly vitamin C. Elderberries are often used in syrups, jams, and wines, but they should be cooked before consumption, as raw berries can be toxic. The elderberry plant also has a long history in traditional medicine, where it has been used to help treat colds and flu symptoms. Additionally, the flowers of the elderberry plant can be made into teas or used in culinary dishes, adding a fragrant flavor.
