Cloves are rich in polyphenols, plant compounds that help fight free radicals and reduce oxidative stress in the body . Eugenol, in particular, has demonstrated potent anti-inflammatory properties in cell and animal studies, potentially helping to disrupt inflammatory pathways . Some researchers suggest that clove's antioxidant and anti-inflammatory effects could even support brain health by reducing neuroinflammation—a factor in neurodegenerative conditions .
2. Supports Oral and Gum Health
One of the most well-known traditional uses of cloves is for oral health. Eugenol has antibacterial properties that can help eliminate bacteria responsible for bad breath, plaque, tartar, and gum disease . Some studies have found that mouthwashes containing clove, along with other herbs like tea tree oil and basil, can reduce bacteria levels in the mouth .
Important caveat: While clove oil has been used for toothache relief, experts caution against applying concentrated clove oil directly to gums as it can cause irritation, burning, or inflammation . For safe use, consider diluted forms or products formulated for oral care.
3. Blood Sugar Management Support
Several studies suggest that clove compounds, particularly eugenol, may help with blood sugar control. In one small study, both pre-diabetic and non-diabetic adults who took daily clove extract for 30 days showed lower blood sugar levels after meals . Researchers believe clove polyphenols may block a liver enzyme involved in glucose processing .
Crucial safety note: While this is promising research, if you have diabetes or are taking insulin or other blood sugar medications, do not start taking clove supplements without talking to your doctor. Combining eugenol with diabetes medications may cause blood sugar levels to drop too low (hypoglycemia), which can be life-threatening .
4. Digestive Comfort and Traditional Uses
In traditional systems like Ayurveda and Traditional Chinese Medicine, cloves have long been valued for digestive health . Clove tea has been used to soothe nausea, reduce gas and bloating, and support overall digestive comfort . In TCM, clove is considered "warm in nature" and is used to "warm the middle" and relieve cold-related digestive discomfort, such as stomach cold vomiting and hiccups .
5. Other Potential Benefits
Preliminary research suggests cloves may also offer benefits in other areas:
Pain relief: Eugenol has analgesic (pain-relieving) properties . Historically, clove oil was used to numb gums.
Antimicrobial effects: Clove and its oil have demonstrated antibacterial, antiviral, and antifungal properties in lab studies .
Bone health: Cloves contain manganese, which plays a role in bone health, making them a modestly supportive addition to a healthy diet for musculoskeletal support .
Mood and stress: The aroma and compounds in cloves may help promote a sense of warmth and calm .
How to Use Cloves Safely
While cloves are generally safe when used as a spice in cooking, concentrated forms like oils and supplements require caution.
Recommended Safe Uses:
Culinary: Use whole or ground cloves in baked goods, sauces, soups, or teas.
Clove Tea: Steep 1-2 cloves in hot water for a mild, soothing beverage.
Food-based: Add ground cloves to oatmeal, smoothies, or savory dishes.
Caution Required:
Clove Oil: This is highly concentrated and can be toxic if ingested in large amounts. Ingestion of 10-30 milliliters of clove oil can cause liver damage, seizures, and loss of consciousness .
Supplements: Human research on clove supplements is limited. Use them cautiously and under professional guidance.
Who Should Avoid Cloves?
Consult a healthcare professional before using clove products if you:
Are pregnant or breastfeeding: Safety has not been established .
Take blood thinners or have a bleeding disorder: Eugenol can affect blood clotting .
Are scheduled for surgery: Cloves can affect blood sugar levels and clotting .
Final Thoughts
Cloves are a valuable natural remedy with genuine health-promoting properties, supported by both traditional wisdom and modern science. They can be a beneficial addition to a healthy diet for supporting digestion, oral health, and potentially blood sugar and inflammation management. However, they are supportive tools, not cures or treatments for serious medical conditions . The key to using cloves safely is to respect their potency. Enjoy them in your meals and teas, but be cautious with concentrated forms like essential oils and supplements.
