Evidence Review

Elderberry extract has usually been tested together with other ingredients, so it’s unclear how well elderberry alone works.
In young children with repeated respiratory infections, a product containing elderberry and other immune-supporting ingredients did not reduce infections during treatment but lowered infections by half in the months after.
The study wasn’t blinded, so results should be interpreted cautiously.
