The headline “With just two cloves a day, you can prevent many diseases…” is a common wellness claim that is overstated. Eating cloves (the spice) can be part of a healthy diet, but there is no strong evidence that consuming two cloves daily can prevent many diseases on its own.
What cloves may offer
Cloves contain compounds such as eugenol, which has antioxidant and antimicrobial properties in laboratory studies. As a food ingredient, cloves may:
- Support overall antioxidant intake
- Add flavor without extra salt or sugar
- Have mild effects on oral bacteria when used appropriately
What cloves have not been proven to do
Cloves have not been proven to prevent or cure:
- Cancer
- Heart disease
- Diabetes
- Infections
- High blood pressure
- Other serious illnesses
Safety considerations
- Large amounts of cloves or clove oil can be harmful and may increase bleeding risk, especially for people taking blood-thinning medicines.
- Clove oil should not be swallowed unless specifically formulated and advised for that use.
- People with medical conditions or upcoming surgery should ask a healthcare professional before using concentrated clove products.
Using small amounts of cloves as a spice can be a healthy choice, but disease prevention is best supported by proven habits: a balanced diet, regular physical activity, avoiding smoking, good sleep, and appropriate medical care.
