What is it? Overview Usage Side Effects and Warnings

What is Elderberry?

Native Americans used tea made from elderberry flowers to treat respiratory infections. They also used the leaves and flowers in poultices applied to wounds, and the bark, suitably aged, as a laxative. The berries are frequently made into beverages, pies, and preserves, but they have also been used to treat arthritis.

A product containing elderberry, as well as small amounts of echinacea and bee propolis , has been widely marketed as a cold and flu remedy. Weak evidence suggests that this mixture may stimulate the immune system and also inhibit viral growth. 1 In a preliminary double-blind study, this mixture was found to reduce symptoms and speed recovery from influenza A, the type of influenza for which flu shots are given. 2 A few of the participants in this study had influenza B (a milder form of influenza), and the elderberry mixture appeared to be helpful for them as well. Another preliminary double-blind study evaluated people with influenza B, and also found benefit. 3

Elderberry has also shown some preliminary promise for use in other viral infections, including HIV 4...

Safety Issues

Elderberry flowers are generally regarded as safe. Side effects are rare and consist primarily of occasional mild gastrointestinal distress or allergic reactions. Nonetheless, safety in young children, pregnant or nursing women, or those with severe liver or kidney disease has not been established.
