Elderberry
Elderberry is the dark purple fruit of the black elder, Sambucus nigra. It is rich in anthocyanins and is mostly studied as an extract for colds and flu.
Also listed as Black Elderberry, Black Elderberry Extract, Black Elderberry Powder, Sambucus nigra
Raw berries are a different safety question
Raw or unripe berries, leaves and stems contain substances that can release cyanide and cause nausea, vomiting and severe diarrhea. Cooking destroys the toxin. 1
Who needs extra caution?
NIH notes possible effects on glucose metabolism and a potential reduction in the effectiveness of immunosuppressant medicines. These are reasons to discuss use when diabetes or immune-suppressing treatment is involved. 2
Safety during pregnancy and breastfeeding is poorly understood. 1
