Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Green onion (Allium fistulosum), also known as scallion or spring onion, has a long-standing history in traditional medicine systems, particularly in East Asia. In Traditional Chinese Medicine (TCM), green onion is considered warming and is commonly used to treat the early stages of colds, coughs, nasal congestion, and other mild respiratory ailments. Classical texts and folk remedies often mention decoctions or poultices made from green onions to help "expel wind-cold" from the body and promote sweating, believed to aid in the resolution of respiratory infections.
Despite its established traditional use, scientific validation for these respiratory benefits remains limited. While green onions contain compounds such as allicin, flavonoids, and sulfur-containing molecules with some antimicrobial and anti-inflammatory properties, there is a lack of clinical trials or robust pharmacological studies directly linking green onion consumption or extract use to improved respiratory function or outcomes in humans. Most available scientific literature focuses on garlic (Allium sativum), a close relative, rather than green onion. Thus, while tradition supports its use for mild respiratory issues, the evidence is not strong or scientifically conclusive.
