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
What Is Elderberry Used for Today?
A product containing elderberry, as well as small amounts of
, 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.
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.
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.
Elderberry has also shown some preliminary promise for use in other viral infections, including
Based on promising results in an
study, researchers performed a small
study on the potential benefits of elderberry for improving cholesterol levels.
Unfortunately, at the dose used, no benefits were evident.
Elderberry-flower tea is made by steeping 3 to 5 g of dried flowers in 1 cup of boiling water for 10 to 15 minutes. A typical dosage is 1 cup 3 times daily. Standardized extracts should be taken according to the directions on the product's label.
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.
