Elderberry syrup or tea may help reduce the duration and severity of cold and flu symptoms, but the evidence for these benefits is uncertain. Claims that elderberry products can prevent viral infections or boost immunity are unproven.

Daily nasal irrigation (nasal rinses) may reduce symptom severity and the duration of a cold. It can also relieve the congestion caused by sinus infections and allergies. By means of a squeeze bottle, neti pot, or battery-powered system, saline is inserted into one nostril and flows out the other.
