From time to time, home remedies resurface during cold season, and one of the more unusual suggestions involves placing whole cloves into a peeled onion and leaving it in the room overnight. While this practice may sound surprising, it has been passed down in many households as a way to create comfort during periods of congestion. Although it is not a medical treatment or cure, understanding the reasoning behind it helps separate tradition from science.
The method itself is straightforward. A peeled onion is studded with several whole cloves and placed on a plate near the bedside. In earlier generations, people believed this combination could cleanse the air or draw out illness. Modern science does not support those claims. Onions contain sulfur compounds and antioxidants, and cloves contain a natural compound called eugenol, known for its aromatic and mild antimicrobial properties. However, these ingredients do not remove viruses from the air or cure respiratory infections.
Any perceived benefit is largely sensory. The strong aroma may help temporarily clear nasal passages, much like other pungent scents. Onions can also release slight moisture into the surrounding air, which may make a dry room feel more comfortable. The ritual itself—preparing something natural and placing it near a resting space—can also provide emotional reassurance, especially when someone is feeling unwell. Comfort and relaxation can play a supportive role in rest and recovery.
For those who choose to try it, basic hygiene is important. Use a fresh onion, place it on a clean surface, discard it after a day, and wash hands afterward. For more effective congestion relief, steam inhalation or humidified air may offer greater comfort. In the end, the onion-and-clove tradition is best viewed as a cultural ritual that may create a soothing atmosphere—but it should not replace evidence-based medical care when needed.
