Allium species, particularly garlic (Allium sativum) and onion (Allium cepa), have a long history of traditional use in the management of respiratory conditions, including sinus congestion. In various folk medicine systems, these plants have been used for their presumed expectorant, antimicrobial, and anti-inflammatory properties. The pungent sulfur compounds (such as allicin) released when garlic or onion is crushed are thought to help clear nasal passages and reduce mucus buildup, often by inhaling vapors or consuming the raw bulbs. However, the scientific evidence supporting these effects in the context of sinus congestion is limited and largely anecdotal. Some laboratory and animal studies suggest that Allium species possess mild antimicrobial and anti-inflammatory activities, which could theoretically contribute to relieving upper respiratory symptoms, but robust clinical trials in humans targeting sinus congestion specifically are lacking. Thus, while use of Allium for congestion is rooted in tradition and historical usage, there is insufficient high-quality scientific validation to strongly support its efficacy for this indication.
