Holding a clove under your tongue for 5 minutes is a popular home remedy claim, but the actual effects are more modest than many online posts suggest.
What may happen
1. You may feel a numbing or warming sensation
- Cloves contain eugenol, a natural compound with mild numbing and soothing properties.
- Eugenol is used in some dental products because it can temporarily reduce discomfort.
2. Saliva production may increase
- The strong flavor and aroma can stimulate saliva flow.
3. You may get temporary mouth-freshening effects
- Clove’s aromatic compounds can mask odors and have antimicrobial activity in laboratory settings.
What it does not reliably do
There is no strong scientific evidence that holding a clove under your tongue for 5 minutes:
- “Cleans the blood”
- Opens blocked arteries
- Cures diabetes
- Melts fat
- Permanently improves circulation
- Replaces medical treatment for infections or chronic conditions
Safety considerations
- A small amount of clove as a spice is generally safe for most people.
- Concentrated clove oil can be harmful if swallowed in large amounts and may irritate tissues.
- Frequent use of cloves directly in the mouth may irritate gums or oral tissues in some people.
- People taking blood-thinning medicines or those with bleeding disorders should be cautious with high amounts of clove products because eugenol may affect blood clotting.
If you enjoy the taste, using clove as a spice in food or an occasional oral freshener is generally reasonable. It should be viewed as a flavoring or traditional remedy—not a proven treatment for health problems.
