Cloves are more than a warming kitchen spice — they’re a concentrated herbal remedy used for centuries in Ayurveda, Unani and traditional Chinese medicine. Modern research supports many of these uses: cloves contain eugenol and other compounds that have antioxidant, antibacterial and anti-inflammatory effects. Here’s what the evidence and traditional practice say, in clear, practical terms.

Roasted cloves and respiratory relief

Roasted cloves have long been chewed or inhaled to ease coughs and congestion. Eugenol helps loosen mucus and can temporarily clear airways; steam inhalation with cloves may relieve blocked noses and reduce coughing during colds and seasonal infections. People with asthma or allergies sometimes report short-term relief after chewing a roasted clove, but cloves are not a substitute for prescribed inhalers or medical care.

A digestive ally

Cloves stimulate digestive enzymes and can improve digestion when used in small amounts. Chewing a clove may reduce nausea and help relieve gas or bloating after a heavy meal. Their antibacterial properties can also help guard against some digestive infections, but cloves should be used as a complementary measure alongside medical treatment when needed.

Natural pain relief and anti-inflammatory action

Eugenol in cloves acts as a natural analgesic and anti-inflammatory agent. Chewing a clove or applying diluted clove oil to an aching tooth or inflamed gum can bring rapid, temporary relief. Clove preparations are also used traditionally for headaches and general inflammation, although concentrated clove oil must be used carefully to avoid irritation.

Boosting immunity with antioxidants

Cloves are rich in antioxidants that neutralize free radicals and reduce cellular damage. Regular, moderate use of cloves as part of a balanced diet may support overall immune resilience and help the body withstand minor viral and bacterial infections during seasonal changes.

Oral care and fresh breath

Clove has well-known antibacterial effects on mouth bacteria, making it useful for reducing bad breath, toothache and gum inflammation. Many oral care products contain clove extract for this reason. For immediate relief, chewing a clove or using a properly diluted clove oil rinse can be effective — always avoid undiluted oil on sensitive tissues and consult a dentist for persistent problems.

Support for blood sugar and heart health

Some studies suggest compounds in cloves can help regulate blood sugar levels and improve insulin function when paired with a healthy diet. Cloves may also support cardiovascular health by helping regulate blood flow and cholesterol levels, although they should not replace medical therapies for diabetes or heart disease.

Liver protection and skin benefits

The antioxidant profile of cloves can help protect the liver from toxin-related damage and support its detoxifying role. Topically, clove oil (diluted) can help treat acne and skin infections because of its antibacterial properties; skin patch tests are recommended first to check for sensitivity.

Use, dosage and safety

Cloves are safe in culinary amounts. Excessive consumption or concentrated clove oil can cause nausea, dizziness or liver stress and is particularly risky for children and pregnant women. Avoid applying undiluted clove oil to the skin or mucous membranes and consult a healthcare provider before using cloves as a therapeutic supplement, especially if you have chronic conditions or take medication.

Takeaway

Cloves are a versatile herbal spice with real health properties: they can ease breathing and digestion, reduce pain and inflammation, support oral health, and provide antioxidant benefits for immunity, liver and heart. Used moderately and sensibly — and never as a replacement for medical treatment — cloves can be a valuable, natural addition to everyday health routines.
