Why do some people put onions in their socks at bedtime?

From ancient times to the modern era, generations of people have practised the organic remedy of placing onion-stuffed socks on their feet while sleeping to promote healing.
Onions have long been considered a traditional remedy, rooted in historical and cultural beliefs, with the idea that they can absorb bacteria and viruses, helping to expel germs and toxins from the body. However, this practice remains unproven due to a lack of scientific evidence.
The National Onion Association has stated that there is no scientific evidence to support the claim that a cut raw onion can absorb germs or purify the air of toxins and pollutants. However, there are many old wives’ tales that, while often illogical and seemingly far-fetched, somehow seem to work!
