Why Placing Cloves in an Onion Is a Household Trick Worth Trying

For safety, use a fresh onion, keep it on a clean plate, discard it after 24 hours, and wash hands after handling. For more effective relief, inhaling steam from simmered onion, garlic, cloves, and ginger can ease congestion. In short, this remedy is a comforting tradition, not a treatment—but it can make winter colds a little more bearable.
