Onion (Folk Remedy)

Onion has been used for centuries in folk medicine traditions around the world, valued for its pungent compounds — particularly quercetin and sulfur-containing molecules — that have drawn scientific interest. Research suggests that onion extracts demonstrate antimicrobial activity against certain bacteria and fungi, which may partly explain their longstanding reputation in traditional healing practices. Studies indicate that onion syrup, often prepared by combining sliced raw onion with honey, has been used as a home remedy for coughs, with some preliminary evidence pointing to its potential soothing effects on irritated airways. Onion poultices applied to the chest or placed near the ear also remain popular in various folk traditions, though scientific evidence for these specific applications is still limited, and anyone with persistent symptoms is best served by consulting a healthcare provider.
