Tiny, round elderberry is the storehouse of health benefiting anthocyanin antioxidants. Early settlers of North America were well acquainted to the medicinal uses of elder flowers and berries long before the Spanish and other European exploreres re-discovered about its uses. These small round blue-purple berries have long been attributed to the longevity and wellness of indigenous natives around arctic regions of Northern hemisphere.
European elderberries (S. nigra) or black elder are intensely tart and rarely edible raw. American elder (S. canadensis) or common elder are relatively sweeter and tart. Only Blue or purple elders are edible and other color variants are just avoided for their possible toxicity.
