Elderberry (Sambucus nigra)
Berry extract supporting immune response during cold and flu season.
What it is
Black elderberry (Sambucus nigra) extract is rich in anthocyanins and has been traditionally used for immune support during respiratory illness.
How it works
Anthocyanins and flavonoids inhibit viral entry; stimulate cytokine production for immune activation.
What the evidence says
Moderate evidence for reducing duration and severity of colds/flu; best used at illness onset.
Safety Notes
- Only use commercially prepared extracts — raw elderberries contain cyanogenic glycosides. Do not use during cytokine storm.
- Use caution with: autoimmune disease (caution), organ transplant (avoid).
- immunosuppressants: Elderberry stimulates immune function; may counteract immunosuppressive drugs.
- diuretics: Elderberry may have mild diuretic effects.
