10 Evidence-Based Health Benefits of Cloves

Introduction

Cloves (Syzygium aromaticum) are tiny flower buds with a big reputation. Known for their warm, aromatic flavor, they’ve been used for centuries in cooking and traditional medicine. But beyond taste, modern science has confirmed that cloves contain powerful compounds—especially eugenol—that offer real health benefits.

Here are 10 evidence-based health benefits of cloves that make them more than just a kitchen spice.

1. Packed with Antioxidants

Cloves are among the most antioxidant-rich spices, outranking many fruits and vegetables. Antioxidants help neutralize free radicals, protecting cells from oxidative stress, which contributes to aging and chronic disease.

2. Support Digestive Health

Eugenol in cloves stimulates digestive enzymes, helping break down food more efficiently. Clove teas or small amounts in meals may reduce gas, bloating, and indigestion.

3. Natural Anti-Inflammatory

Compounds in cloves, including eugenol and flavonoids, have anti-inflammatory properties. Research in the Journal of Ethnopharmacology suggests cloves may help reduce markers of inflammation, potentially easing discomfort in conditions like arthritis.

4. Blood Sugar Regulation

Several studies have found that clove extracts may improve insulin sensitivity and glucose metabolism. While not a substitute for medication, cloves may help support healthy blood sugar levels when part of a balanced diet.

5. Oral and Dental Health

Cloves have long been used in dentistry. Eugenol provides pain relief for toothaches and reduces harmful oral bacteria. Chewing a clove or using clove oil (diluted) may freshen breath and support gum health.

6. Antimicrobial Properties

Cloves exhibit antibacterial, antifungal, and antiviral activity. Studies show clove oil can fight bacteria like E. coli and fungi like Candida albicans. This makes cloves useful for both oral hygiene and traditional remedies.

7. May Support Liver Health

Animal studies suggest eugenol may help protect the liver from oxidative stress and damage. While human research is limited, these findings support the traditional use of cloves for detox and wellness.

8. Joint and Bone Support

Cloves contain compounds like manganese, which is essential for bone health. Combined with anti-inflammatory properties, cloves may support mobility and reduce stiffness over time.

9. May Improve Circulation

By reducing oxidative stress and inflammation, cloves may support vascular health and blood flow. Improved circulation can benefit heart health and energy levels.

10. Immune System Support

With antimicrobial and antioxidant properties, cloves may help the body defend against infections. Traditional remedies often use clove tea during the cold and flu season for this reason.

Best Ways to Use Cloves

• Culinary: Add to soups, stews, rice, or baked goods.

• Tea: Steep 2–3 cloves in hot water with ginger, lemon, or cinnamon.

• Oral care: Chew 1–2 cloves for fresh breath.

• Blends: Combine with turmeric or cinnamon for added benefits.

Risks and Safety Considerations

While cloves are safe in small amounts, concentrated oils or supplements can cause:

• Stomach irritation

• Increased bleeding risk (due to eugenol)

• Hypoglycemia, when combined with diabetes medication

Safe daily use: about 2–3 whole cloves or ¼ teaspoon ground. Avoid clove oil ingestion.
