Rating (out of 5): 2

Citrus fruits, such as oranges, lemons, and limes, have been traditionally used in various cultures to help alleviate symptoms of congestion, particularly in the context of the common cold or respiratory infections. This traditional use is largely based on the high vitamin C content of citrus fruits and their tangy, aromatic qualities, which are believed to help clear nasal passages and provide relief from stuffiness. Citrus fruits are often consumed as fresh fruit, juices, or in hot drinks like lemon tea with honey, which are popular home remedies for soothing sore throats and reducing congestion. However, scientific evidence directly supporting the efficacy of generic "citrus" for congestion is limited. Some studies have examined the role of vitamin C in reducing the duration and severity of cold symptoms, but results have been mixed, and vitamin C supplementation does not consistently prevent or treat congestion. The aromatic oils found in citrus peels, such as limonene, may have mild decongestant properties when inhaled, but rigorous clinical trials are lacking. In summary, while the use of citrus for congestion is supported by longstanding traditional practice, robust scientific validation is still limited, and its benefit is likely modest and supportive rather than curative.
