Synergy
What is happening. Echinacea and elderberry are commonly combined for upper respiratory and cold or flu symptom support through complementary immune-modulating effects.
Mechanism. Elderberry anthocyanins have antiviral and cytokine-modulating activity while echinacea stimulates innate immune responses, providing overlapping support against respiratory viral symptoms.
Recommendation. Acceptable to combine for short-term immune support during cold and flu season. Use short courses rather than continuous long-term use.
