In the herbal tradition of Europe, the flowers and berries of the European black elder have been used for centuries as a general healthful tonifier, and especially to help prepare for a cold winter season. Elder is rich in anthocyanins and bioflavonoids, which are known for supporting the body's natural defenses. Planetary Herbals Full Spectrum™ Elderberry Fluid Extract is made from both the flowers and berries, providing you with a full spectrum of elder activity.
