Synopsis

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

Green onion (Allium fistulosum), also known as scallion or spring onion, has a long history of use in traditional medicine systems, particularly in East Asia. In Traditional Chinese Medicine (TCM), green onion is classified as a warming herb and is commonly used to address early-stage colds, nasal congestion, and sinus issues. Its use is often in the form of decoctions or teas, intended to "expel wind-cold" and promote sweating, which is believed to help relieve symptoms of sinus congestion and respiratory discomfort.

However, scientific evidence supporting green onion's direct benefits for the sinuses is limited. While green onion contains some sulfur compounds (similar to garlic and onions) that have mild antimicrobial and anti-inflammatory effects, there are no robust clinical studies demonstrating its effectiveness specifically for sinus health or sinusitis relief. The rating of 2 reflects the strong traditional usage but a lack of rigorous scientific validation.

In summary, green onion's reputation for supporting the sinus system is grounded primarily in traditional herbal practices rather than modern clinical research. It may offer mild symptomatic relief due to its warming nature and aromatic compounds, but evidence remains anecdotal and based on historical usage.
