Worth trying at the first sign of a cold; evidence is promising but not definitive, and it won't prevent infection.
Elderberry is the fruit of the Sambucus nigra plant, rich in anthocyanins and flavonoids. Supplements typically use standardized extracts or syrups made from the berries. Its primary proposed mechanism involves modulating immune responses and interfering with viral entry. Randomized trials suggest it can lessen the severity and shorten the duration of upper respiratory symptoms when taken early in illness. People most likely to benefit are those exposed to seasonal viruses or seeking adjunct symptom relief during acute colds or influenza.

How It Works
Elderberry flavonoids, particularly anthocyanins, may interfere with viral hemagglutinin and neuraminidase activity, limiting viral entry and replication. The extract also appears to modulate cytokine production, potentially upregulating beneficial immune responses while tempering excessive inflammation.
