Contain eugenol, a compound with antibacterial, antiviral, and antifungal effects.
Used traditionally in dentistry for toothaches and infection control.

Important Limitation

Onions do not “pull germs” from the body or air.
Any antimicrobial effect is limited to the surface of the onion.
The so-called “purifying” effect mostly comes from aromatic compounds released into the air—pleasant, but not a substitute for medical care or proper hygiene.

What You Might Actually Notice

Aromatherapy benefit: The scent may help open nasal passages slightly.
Humidity: Onions release moisture, which can soothe dry airways.
Odor masking: Can cover stale or unpleasant room smells.
Psychological comfort: The ritual itself may provide a sense of relief and well-being.

What This Remedy Doesn’t Do

Cure colds, flu, or infections
Replace vaccines, handwashing, or medical treatment
“Draw out” illness from your body (this is a myth)

Warning: Cut onions left out for too long can grow bacteria or mold. Discard after 24–48 hours.

Safer Way to Try It

Use a fresh onion and whole cloves.
Place on a clean dish in your bedroom (keep away from food).
Discard after 24 hours.
Wash hands thoroughly after handling.
Do not eat the onion—it’s for aroma only.

Alternative Method

Simmer onion, garlic, cloves, and ginger in water, then inhale the steam for 5–10 minutes. This can help ease congestion naturally.

Final Thoughts

This onion-and-cloves practice isn’t magical—but it isn’t pointless either. It’s a gentle, aromatic ritual rooted in home care traditions, offering mild comfort during illness.

Use it if it brings you peace, but always alongside proper medical treatment.

Combining traditional wisdom with modern science is the best approach to gentle, effective home remedies.
