Source of validity: Traditional
Rating (out of 5): 2

Fruits have been traditionally used in many cultures to help relieve symptoms of colds, including congestion. The use of fruits for this purpose is primarily rooted in traditional and folk medicine rather than strong scientific validation. Citrus fruits like oranges, lemons, and grapefruits are commonly consumed during colds due to their high vitamin C content, which is believed to support the immune system. Other fruits, such as pineapples, have been recommended in traditional remedies for their supposed mucolytic (mucus-thinning) properties, although strong clinical evidence is lacking.

While fruits are rich in vitamins, antioxidants, and fluids—which may generally support health and hydration during illness—there is limited scientific evidence specifically validating their role as decongestants. Most clinical trials on vitamin C and similar nutrients from fruits show only a modest reduction in cold duration or severity, but not a significant decongestant effect. The tradition persists largely because fruits are refreshing, hydrating, and easy to consume during illness, and because popular wisdom associates natural foods with health benefits.

In summary, the use of unspecified fruit as a decongestant is mainly traditional, and while fruits may support overall wellness during a cold, robust scientific evidence for a direct decongestant effect is lacking.
