Herbal blends have been traditionally used in various cultures to support the prevention and treatment of colds. Many such blends contain ingredients like echinacea, elderberry, ginger, garlic, and licorice root, which have individually been used for centuries in folk and traditional medicine systems to support immune function and alleviate symptoms of respiratory infections. Historical records from European, Native American, and Asian medicinal practices describe the use of herbal teas, tinctures, and decoctions during cold seasons to "ward off" illness or reduce severity and duration.

Scientific research on these blends as a whole is limited; most studies focus on individual herbs. For example, echinacea and elderberry have some evidence, including randomized controlled trials, suggesting a potential to modestly reduce the likelihood or duration of colds, but the results are inconsistent and often criticized for methodological flaws. There is little high-quality clinical evidence supporting the use of complex herbal blends for cold prevention specifically, and effects may depend on the specific formulation. However, the long-standing traditional use and some preliminary scientific findings give a moderate, but not strong, basis for their use.
