Properties:

Antiviral, antimicrobial, antioxidant, immune-stimulant, diaphoretic, anti-inflammatory

Dosage:

Syrup: 1-2 tablespoons (approx. 15-30 ml) daily for immune support; up to 4 times daily at the acute onset of a cold or flu.

Dried Berries: 5-15 grams daily (must be thoroughly cooked into a decoction, syrup, or extract).

(Break for at least 2 weeks after 12 weeks of continuous daily preventive usage; acute use should generally be limited to 5 to 10 days).

Benefits:

Supports robust immune function, helps reduce the severity and duration of cold and influenza symptoms, and provides exceptionally high levels of anthocyanins and antioxidants that protect cells from oxidative stress. Acting as a mild diaphoretic, it can also help encourage a gentle, healthy fever response to clear pathogens.

Hormonal Benefits:

Helps modulate systemic inflammation and supports immune-endocrine balance during acute stress or infection, assisting the body in recovering equilibrium efficiently.

Avoid if:

You are consuming raw, unripe, or undercooked berries, bark, leaves, or roots (these contain cyanogenic glycosides which can cause severe nausea, vomiting, diarrhea, and cyanide poisoning). Also avoid if you have a known allergy to plants in the Adoxaceae family or active autoimmune flares where over-stimulation of the immune system is contraindicated.

Cautions:

Avoid high therapeutic doses if pregnant or breastfeeding due to a lack of long-term safety data. Excessive or raw consumption can cause severe gastrointestinal distress, abdominal cramps, or weakness.

You should also be cautious if you are taking any of the following:

Immunosuppressant drugs (elderberry stimulates immune function, which may theoretically counteract the medication), Diuretics (potential additive effects), or Antidiabetes medications (may have mild blood-sugar-lowering effects).
