For generations, people have followed the old household remedy: stick cloves into a peeled onion and leave it in a room overnight to ease cold symptoms. While it may sound unusual, many families swear by the ritual, especially during flu season. The practice is rooted in tradition, comfort, and aroma rather than proven medical benefits.

Here’s how it’s usually done: peel a fresh onion, insert 6–12 whole cloves into its surface, and place it on a plate near the bedside or in a common area. Supporters say it can ease congestion, freshen the air, mask odors, and create a calming atmosphere. While science doesn’t support claims that it “absorbs germs” or cures illness, both onions and cloves contain natural compounds with mild antibacterial, antifungal, and aromatic properties. Onions release sulfur compounds and antioxidants, while cloves contain eugenol, known for its antiseptic and numbing effects.

Even without curing illness, the remedy may have real benefits: the aroma can open nasal passages, mild moisture release can soothe sinuses, and the ritual itself offers comfort and emotional support.

For safe use, place the onion on a clean plate, discard after 24 hours, and avoid eating it. For more effective relief, consider inhaling steam with onions, garlic, and cloves.

Ultimately, the clove-and-onion tradition is a mix of history, scent, and family memory. It won’t replace proper medical care, but it can bring a sense of warmth, comfort, and calm during sick or chilly days.
