Citrus oil, especially from sources like orange, lemon, and grapefruit, has traditionally been used in various cultures to support respiratory health and alleviate symptoms associated with colds. Folk medicine often recommends inhaling citrus oil vapors or using them in balms and chest rubs, based on the belief that their strong aroma and volatile components can help clear nasal passages and promote a sense of well-being.

The perceived benefit of citrus oils for colds is largely attributed to their pleasant scent, which may temporarily relieve the sensation of nasal congestion, and their mood-lifting effects, which can help improve comfort during illness. Some laboratory studies have identified antiviral properties in certain citrus oil constituents, such as limonene and citral, but these effects have mostly been demonstrated in vitro (in test tubes) and not in human clinical trials. There is a lack of robust, high-quality scientific evidence specifically supporting the efficacy of citrus oils in treating or preventing colds in humans.

Overall, while citrus oils are popular in traditional and complementary medicine for symptomatic relief of colds, their use is not strongly supported by clinical research. They may be used safely in aromatherapy for comfort, but should not be relied upon as a primary antiviral treatment.
