What is Elderberry Extract?
Black elderberry (Sambucus nigra) is one of the most-studied botanicals for upper respiratory immune support. Its concentrated dark-purple anthocyanins appear to inhibit viral attachment to cell membranes and modulate cytokine signaling during the early stages of viral illness. Multiple clinical trials, including placebo-controlled studies of the Sambucol extract, have shown reductions in cold and flu duration when supplementation begins within 48 hours of symptom onset. Elderberry should not be used as a daily preventive in people with autoimmune conditions, as it gently activates immune signaling. Standard dose during the early stages of upper respiratory illness is 1 teaspoon of standardized syrup three to four times daily.
