What is being studied?

Elderberry is the fruit of Sambucus nigra. Most clinical research has tested extracts, rather than the berries themselves. Anthocyanins and other plant compounds provide possible antiviral and immune-related mechanisms; those hypotheses do not establish fewer infections in people. 1

Questions people ask

Can elderberry reliably prevent colds?

The systematic review did not establish a clear reduction in the risk of catching a cold. 2

Did the later flu trial find faster recovery?

No. The 87-person trial found no benefit for illness duration or severity. 3

Can I eat raw elderberries for the same effect?

Raw or unripe berries pose a poisoning risk; cooking destroys the cyanide-producing toxin. 4

Is elderberry a COVID-19 treatment?

NCCIH reports no good evidence supporting its use for COVID-19. 4
