Created for Planetary Herbals by licensed acupuncturist and clinical herbalist Michael Tierra. A clinician since 1972, Michael is an authority on the world's herbal traditions, and has authored several respected herb books. In the herbal traditions of Europe, elderberry 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. Planetary Herbals' delicious Elderberry Syrup unites age-old tradition with modern science to support natural defenses. Lifestyle Recommendations: To support natural defenses, eat well, get plenty of rest and exercise regularly. Avoid excessive consumption of cold and raw foods during winter. Other Planetary Herbals products to maintain natural defenses and seasonal health include: Astragalus Jade Screen, Echinacea, Yin Chiao Classic, Yin Chiao-Echinacea Complex, and Old Indian Wild Cherry Bark Syrup.
