Elderberry supplements are made from the fruit or flowers of elderberry plants, and are often used for colds or flu.
Elderberries contain natural substances called flavonoids. They seem to help reduce swelling, fight inflammation, and boost the immune system.
Limited studies have found that elderberry eases flu symptoms like fever, headache, sore throat, fatigue, cough, and body aches. The benefits seem to be greatest when started within 24 to 48 hours after the symptoms begin. One study found that elderberry could cut the duration of flu symptoms by more than 50%.
Elderberry has also been promoted for COVID-19, but there is no evidence that it works.
A few studies have suggested that elderberry could help with bacterial sinus infections or bronchitis. More research needs to be done.
Some people use elderberry for high cholesterol, HIV, and many other conditions. For now, we dont have good evidence to support these uses.
There is no standard dose of elderberry. For flu, some studies have used 1 tablespoon of an elderberry syrup extract four times a day. Another common form of elderberry is a lozenge, often with zinc, that is taken numerous times daily after a cold begins. Ask your health care provider for advice.
Cooked elderberries are used as a flavoring in foods and wine. Elderberries are also in foods like jams and pies. No research has found that these foods have any health benefits. Raw elderberries, as well as other parts of the elder tree, are poisonous.
Because of serious potential risks, elderberry is not recommended for children or for women who are pregnant or breastfeeding.
