Scallion (Allium fistulosum), also known as green onion or spring onion, has a long history of use in traditional medicine, particularly in East Asia. In Traditional Chinese Medicine (TCM), scallions are used to "release the exterior" and are commonly included in remedies for early-stage colds, flu, and congestion. The white part of the scallion is typically used, often prepared in teas or congees, based on the belief that it has warming properties that help expel wind-cold pathogens and promote sweating, thereby relieving symptoms like nasal congestion and mild upper respiratory discomfort.

However, there is limited scientific research directly supporting the use of scallion for treating congestion. Some in vitro studies have demonstrated that scallions contain sulfur compounds with mild antimicrobial effects, and they may exhibit slight anti-inflammatory or immune-modulating properties. However, these findings are not directly linked to the clinical relief of congestion in humans. As such, the primary justification for its use comes from historical tradition and anecdotal reports rather than robust scientific validation.

In summary, while scallion's use for congestion is well established in traditional practice, especially in East Asian cultures, scientific evidence remains minimal, and clinical studies are lacking. Therefore, its effectiveness for this purpose should be considered more traditional than evidence-based.
