In the herbal traditions of Europe, elderberry (Sambucus nigra) has been used since antiquity as a wine, a syrup and a warming winter cordial. The berries are rich in bioflavonoids and anthocyanins, a unique class of constituents known for their beneficial effect on cellular function, and particularly for their role in maintaining the integrity of capillary walls and immune defenses.
