Elderberry is a small, dark purple fruit that grows on the Sambucus plant, commonly found in Europe and North America. The berries are rich in vitamins, particularly vitamin C, and are often used in syrups, jams, and dietary supplements. They are known for their potential health benefits, including supporting the immune system and reducing the duration of colds and flu. The elderberry plant also produces clusters of white flowers, which can be used to make elderflower cordial or tea. While elderberries are nutritious, they should be cooked before consumption, as raw berries can be toxic. Overall, elderberry is valued for its culinary and medicinal uses.
