The Healing Benefits of Cloves: Natural Remedies for Improved Wellness
Cloves are aromatic flower buds commonly used in cooking, traditional medicine, and herbal remedies. They are known for their warm, slightly sweet flavor and their high concentration of eugenol, a natural compound that has antioxidant, antimicrobial, and pain-relieving properties.
Cloves may support oral health, digestion, and general wellness when used appropriately. However, it is important to distinguish traditional uses and promising laboratory research from benefits that have been firmly demonstrated in humans.
1. What are cloves?
Cloves come from the unopened flower buds of the tropical evergreen tree Syzygium aromaticum. They are harvested, dried, and used whole, ground, or as a source of essential oil.
Cloves have been used in traditional Asian, African, Middle Eastern, and European remedies for generations, particularly for tooth discomfort, digestive complaints, and flavoring warm herbal drinks.
Important nutrients and natural compounds
Cloves contain several substances that contribute to their biological activity.
-
Eugenol: The main aromatic compound, studied for its local anesthetic, anti-inflammatory, and antimicrobial effects.
-
Polyphenols: Plant compounds with antioxidant activity.
-
Beta-caryophyllene: A naturally occurring aromatic compound studied for its potential anti-inflammatory effects.
-
Manganese: A mineral involved in normal bone formation and metabolism.
-
Dietary fiber: Present in the whole spice, although the quantity consumed in ordinary cooking is small.
Cloves are concentrated in their flavor and plant compounds, so only a small amount is usually needed.
2. The major health benefits of cloves
1. May help relieve toothache
One of the best-known traditional uses of cloves is temporary relief of tooth discomfort.
How it may work: Eugenol can reduce pain sensation locally and has anti-inflammatory properties. Eugenol has also been used in certain professional dental materials.
Practical use: Clove-based dental preparations may provide temporary relief when used according to their product instructions.
Important: Do not place undiluted clove essential oil directly on a tooth or gums. It can burn or irritate tissue. Cloves cannot treat tooth decay, an abscess, or the underlying cause of dental pain. See a dentist for persistent pain or swelling.
2. May support digestion
Cloves are traditionally used to ease feelings of fullness, gas, and digestive discomfort.
How they may work: Their aromatic compounds may influence digestive activity, but much of the supporting evidence comes from traditional use and laboratory or animal studies.
Practical use: Try a mild clove infusion after a meal if you enjoy its flavor. There is not enough strong clinical evidence to say that cloves reliably treat indigestion, acid reflux, or bloating.
People with reflux or a sensitive stomach should stop using the infusion if it worsens their symptoms.
3. Provide antioxidant compounds
The plant compounds in cloves can help neutralize certain reactive molecules in laboratory experiments.
Why it matters: Oxidative stress is involved in normal aging and several chronic disease processes. Antioxidants are one part of the body’s overall defense system.
What the evidence means: Cloves have strong antioxidant activity in laboratory testing, but this does not prove that eating cloves prevents cancer, heart disease, or other chronic illnesses in humans.
4. May have anti-inflammatory effects
Eugenol and other clove compounds have shown anti-inflammatory activity in experimental studies.
Inflammation is part of the body’s normal immune response, but persistent excessive inflammation can contribute to disease.
Current limitation: It is not established that the amounts of cloves normally eaten produce a meaningful anti-inflammatory effect in people. Cloves should not replace prescribed treatment for arthritis or other inflammatory conditions.
5. Show antimicrobial activity
Clove extracts and eugenol can inhibit certain bacteria and fungi under laboratory conditions.
This has attracted interest in oral care, food preservation, and the development of antimicrobial products.
What it does not mean: Drinking clove water does not sterilize the body, cure infections, or replace antibiotics or antifungal medicines when those treatments are needed.
6. May influence blood sugar regulation
Some laboratory and small human studies have investigated clove extracts and glucose metabolism.
However, evidence is insufficient to establish that cloves reliably lower blood sugar or prevent or treat diabetes.
Practical advice: Use cloves as a culinary spice rather than as a diabetes treatment. If you take insulin or glucose-lowering medication, consult your healthcare professional before using concentrated clove supplements.
7. May support liver health, but evidence is limited
Certain experimental studies suggest that eugenol may affect oxidative stress and markers of liver injury.
These findings do not establish cloves as a liver detox remedy. In fact, high doses of eugenol and clove oil can cause serious liver damage.
Bottom line: There is no good evidence that concentrated clove preparations cleanse the liver or improve liver disease.
8. May contribute to a healthy diet
Cloves add flavor without requiring much salt or sugar. Their plant compounds can complement a diet rich in vegetables, fruits, legumes, whole grains, and other spices.
Their nutritional contribution at ordinary serving sizes is modest, however. Cloves alone are not a substitute for a balanced diet, regular physical activity, sleep, or preventive healthcare.

4. How to use cloves safely
The amount and form of cloves matter. Whole cloves used in food are not equivalent to concentrated clove essential oil.
|
Form |
Practical guidance |
|---|---|
|
Whole cloves |
Use small amounts in cooking and beverages. |
|
Ground cloves |
Use a pinch or the quantity specified in a recipe. |
|
Clove infusion |
Keep it mild; there is no established therapeutic dose. |
|
Clove essential oil |
Do not swallow it or apply it undiluted to the mouth or gums. |
|
Clove supplements |
Seek medical advice before taking concentrated extracts regularly. |
There is no universally established daily dose of cloves for treating health conditions. Ordinary culinary use is generally much safer than medicinal quantities of concentrated extracts.
5. Who should be cautious about cloves?
Although cloves are a common spice, concentrated preparations can cause problems in certain circumstances.
-
People taking blood-thinning medication: Eugenol may affect blood clotting. Ask a healthcare professional before using concentrated clove products, especially if you take warfarin or other anticoagulants.
-
People with diabetes: Concentrated extracts could potentially affect blood glucose. Do not use cloves as a substitute for diabetes medication.
-
People with liver disease: Avoid medicinal doses of clove oil or concentrated eugenol unless specifically advised by a clinician.
-
People with sensitive skin or gums: Clove oil can cause irritation, burns, or allergic reactions.
-
Pregnant or breastfeeding people: Safety data for medicinal doses and concentrated supplements are limited. Ordinary culinary use is different from taking extracts.
-
Children: Never give children clove essential oil to swallow or use it as a teething remedy. Small amounts of swallowed oil can cause serious poisoning.
Large ingestions of clove oil can cause seizures, low blood sugar, and severe liver or kidney injury. If someone swallows clove essential oil accidentally, contact Poison Control promptly in the United States at 1-800-222-1222. Do not induce vomiting.
6. Common claims about cloves: fact versus myth
|
Claim |
What the evidence supports |
|---|---|
|
Cloves cure tooth infections |
No. They may temporarily ease pain but cannot eliminate an infection. |
|
Clove water detoxifies the liver |
No convincing evidence supports this claim. |
|
Cloves cure diabetes |
Not established; limited preliminary research is insufficient. |
|
Cloves kill all harmful bacteria in the body |
Laboratory antimicrobial activity does not establish this effect in humans. |
|
Cloves can reduce inflammation |
Promising laboratory findings exist, but clinical benefits remain uncertain. |
|
Cloves provide antioxidants |
Yes, clove compounds show antioxidant activity in laboratory tests. |
|
Eating cloves in normal food amounts is generally safe |
Yes, for most people, provided they are used in ordinary culinary quantities. |
The overall scientific picture is that cloves have interesting biological properties, but many claims about treating disease go beyond the available evidence.
7. Frequently asked questions
Can I chew one clove every day?
Using a small amount of cloves as food is generally safe for most healthy adults. However, there is no strong evidence that chewing a whole clove daily prevents disease or provides a specific medical benefit. Stop if it irritates your mouth.
Is clove water good to drink in the morning?
You can enjoy a mild clove infusion in the morning if it agrees with your stomach. There is no convincing evidence that drinking it on an empty stomach improves metabolism, burns fat, cleanses the liver, or removes toxins. Avoid making highly concentrated clove water a daily medicinal habit.
Can cloves help with bad breath?
Cloves have a strong aroma and compounds with antimicrobial activity in laboratory studies, but they do not replace brushing, flossing, tongue cleaning, or dental care. Persistent bad breath may indicate gum disease, tooth decay, dry mouth, or another condition.
Are cloves beneficial for men and women differently?
There is insufficient evidence to establish distinct health benefits based on sex. Claims that cloves reliably increase testosterone, improve fertility, balance female hormones, or enhance sexual performance are not well supported by clinical research.
Do cloves help with weight loss?
There is no reliable evidence that cloves alone cause meaningful weight loss. They may help add flavor to foods and drinks without adding much sugar, which can support a healthy eating pattern.
Can cloves improve sleep?
Clove tea may be a comforting bedtime drink, but cloves have not been established as a treatment for insomnia. Avoid adding caffeine-containing ingredients if you are sensitive to caffeine.
8. The best way to include cloves in your wellness routine
For most people, the most sensible approach is to:
-
Use cloves in balanced meals and occasional mild herbal drinks.
-
Avoid swallowing clove essential oil or applying it directly to the gums.
-
Treat research on antioxidants, inflammation, and blood sugar as preliminary rather than proof of a cure.
-
Seek appropriate medical or dental care for persistent symptoms.
-
Consult a healthcare professional before using concentrated clove supplements if you take medication or have an ongoing medical condition.
Final takeaway: Cloves are a useful culinary spice containing eugenol and other plant compounds with promising properties. Their best-established everyday role is as a flavorful food ingredient, while most medicinal benefits remain insufficiently proven in humans.
