What Are Cloves?

Cloves are dried flower buds native to Indonesia and widely cultivated in tropical climates. Used worldwide both as a spice and in medicinal formulas, cloves are recognized for their potent aroma and flavor due to their high content of eugenol, a powerful antioxidant compound. Cloves have a long history in Ayurvedic and traditional Chinese medicine and are a staple in many cuisines.

Nutritional Profile of Cloves

Although consumed in small quantities, cloves deliver a concentrated dose of several vital nutrients. Below is a summary of nutrients found in cloves (per 2 grams, or roughly 1 teaspoon):

Cloves are exceptionally rich in manganese and contain a wide range of beneficial plant compounds—most notably, eugenol, which is responsible for many of their health effects.

Top 12 Health Benefits of Cloves

1. Powerful Antioxidant Properties

   Cloves have a higher antioxidant value than most foods—including even blueberries. The main component, eugenol, helps neutralize harmful free radicals, protecting cells from oxidative damage and lowering the risk of chronic diseases such as heart disease, diabetes, and certain cancers .

2. Antibacterial and Antiviral Activity

   Clove oil shows strong antibacterial effects, capable of inhibiting bacteria like E. coli, Staphylococcus, and various oral pathogens. Compounds in cloves have also demonstrated antiviral activity, particularly against herpes simplex virus .

3. Supports Oral Health

   Clove and clove oil are time-honored remedies for toothaches, gum problems, and dental pain. Eugenol in cloves acts as a natural anesthetic and antiseptic, helping to reduce pain, fight bacteria, and decrease inflammation in the mouth. Some mouthwashes containing cloves can reduce plaque and gingivitis as effectively as commercial rinses .

   • Helps numb tooth pain
   • Reduces oral inflammation and bacteria
   • May assist in treating dental erosion

4. Anti-Inflammatory Effects

   The eugenol and beta-caryophyllene in cloves possess significant anti-inflammatory action, which can lower the body’s inflammatory response and help manage chronic conditions like arthritis and other inflammatory disorders .

5. Natural Analgesic and Pain Relief

   Cloves’ compounds, notably eugenol, have marked antinociceptive (pain-blocking) qualities. Traditionally, clove has relieved tooth, joint, and muscle pain, and scientific research confirms its ability to act on nerves that transmit pain signals .

6. May Help Regulate Blood Sugar

   Some studies suggest that clove extracts may help reduce high blood sugar and improve insulin function, offering potential support for people managing diabetes or at risk of insulin resistance . However, more human studies are needed to confirm these effects.

7. Promotes Liver Health

   Eugenol in cloves may help protect the liver from oxidative damage and improve liver function. Animal research has indicated a reduction in symptoms of liver disorders such as fatty liver disease and cirrhosis when supplemented with clove extracts .

8. May Reduce Risk of Cancer

   High antioxidant content gives cloves anti-cancer potential. Laboratory and animal studies indicate that extracts can slow tumor growth, induce cancer cell death, and protect cells from mutation. More research is needed to understand its effect in humans, but results are promising .

9. Aids Digestive Health

   Cloves have been traditionally used as carminatives to reduce bloating and gas. Modern studies suggest that compounds in cloves may help prevent and heal stomach ulcers, boost digestive enzyme secretion, and improve overall gastrointestinal health .

   • Thickens stomach mucus, protecting against ulcers
   • Relieves gas and bloating

10. Wound Healing and Skin Benefits

    Studies in mice have found that clove oil emulsions can support wound healing and offer anti-inflammatory benefits to the skin. Eugenol also has mild anesthetic and antiseptic properties, which may soothe skin irritation .

11. Respiratory Relief and Freshens Breath

    The strong aroma of cloves helps clear nasal passages and ease coughing. Cloves are a common ingredient in natural cough drops and are also known for their ability to freshen breath, masking odor-causing bacteria in the mouth .

12. Potential to Boost Immunity

    Due to their antibacterial, antiviral, and anti-inflammatory actions, cloves may help fortify the body’s natural defenses. The high concentration of antioxidants reduces oxidative stress on the immune system and supports overall health .

Uses of Cloves in Daily Life

Cloves are highly versatile in both culinary and medicinal applications.

• Cooking: Adds flavor to curries, stews, rice dishes, baked goods, and marinades. Ground or whole cloves are used in spice blends such as garam masala.
• Oral Health: Clove oil or crushed cloves can be applied to the gums or tooth for temporary toothache relief; mouthwashes may contain clove extracts.
• Topical Applications: Diluted clove oil is used in massage oils for relieving muscle and joint pain; also found in some creams for minor skin irritations.
• Aromatherapy: Clove essential oil is inhaled or diffused in the air for its warming, stimulating aroma, and purported immune-boosting effect.

Note: Always dilute clove essential oil with a carrier oil before topical use to avoid irritation.

Possible Side Effects and Risks

While cloves are generally safe in food amounts, using large quantities or concentrated oils may cause adverse effects:

• Allergic reactions in sensitive individuals (skin rashes, breathing difficulty)
• Liver toxicity at high doses (especially from eugenol-rich clove oil in children)
• Bleeding risk: Eugenol can slow blood clotting—use caution if on anticoagulant medication or before surgery
• Gastrointestinal upset: Large amounts can cause nausea, vomiting, or diarrhea

Pregnant and breastfeeding women, young children, and people with bleeding disorders or on blood-thinners should consult a healthcare professional before using clove supplements or essential oil.
