Cloves are small, aromatic flower buds that have been used for centuries in traditional cooking and wellness practices. Known for their warm flavor and distinctive fragrance, these dried flower buds come from the clove tree (Syzygium aromaticum), which is native to the Maluku Islands of Indonesia.
Beyond their culinary uses, cloves contain naturally occurring plant compounds, including eugenol, which has antioxidant and other biological properties that researchers continue to study.
From adding flavor to warm beverages to enhancing savory dishes, cloves offer several ways to support a balanced lifestyle. However, it is important to distinguish between traditional uses, laboratory findings, and benefits that have been demonstrated in human studies.
Let’s explore the potential health benefits of cloves, how to use them, and the precautions worth knowing.
1. Cloves Are Rich in Antioxidant Compounds
One of the most widely studied properties of cloves is their antioxidant activity.
Cloves contain eugenol and other plant compounds that can help neutralize free radicals under experimental conditions. Free radicals are unstable molecules that can contribute to oxidative stress when they accumulate in the body.
A balanced diet rich in antioxidant-containing foods, including fruits, vegetables, herbs, and spices, can help support overall health.
How to use cloves: Add a small amount of ground cloves to oatmeal, homemade smoothies, or warm beverages for extra flavor and plant compounds.
2. Cloves May Support Oral Health
Cloves have a long history of use in traditional dental care. Eugenol, one of their major components, has been studied for its local anesthetic and antimicrobial properties.
Certain dental preparations containing eugenol have been used in professional dentistry. However, this does not mean that chewing whole cloves or applying clove oil can replace dental treatment.
Good oral hygiene remains essential for maintaining healthy teeth and gums.
How to use cloves: Use a small pinch of ground cloves in cooking or enjoy lightly flavored clove tea. For toothache, swelling, or suspected infection, seek advice from a dentist rather than relying on cloves as a remedy.
Avoid applying undiluted clove essential oil directly to your gums or teeth because it can irritate or damage oral tissues.
3. Cloves May Help Support Healthy Digestion
Cloves have traditionally been used in various cultures to complement meals and support digestive comfort.
Their aromatic compounds may influence digestive processes, but strong clinical evidence that cloves reliably relieve bloating, indigestion, or other digestive disorders in humans remains limited.
Including cloves in a balanced diet can be a simple way to add flavor without relying on excessive sugar or salt.
How to use cloves: Simmer one or two whole cloves in a cup of water for approximately 5–10 minutes. Let the drink cool to a comfortable temperature before sipping it.
If digestive symptoms are persistent, severe, or accompanied by vomiting, blood in the stool, or unexplained weight loss, consult a healthcare professional.
4. Cloves Contain Compounds With Antimicrobial Activity
Eugenol and other compounds found in cloves have demonstrated activity against certain microorganisms in laboratory studies.
These findings have attracted scientific interest in the potential applications of clove-derived compounds in food preservation and oral-care products.
Nevertheless, laboratory results do not establish that drinking clove water or eating cloves can treat bacterial, viral, or fungal infections in the human body.
How to use cloves: Incorporate whole or ground cloves into soups, stews, marinades, and other cooked dishes as part of a varied diet.
Do not use clove preparations as a substitute for prescribed antibiotics or other necessary infection treatments.
5. Cloves May Support a Healthy Inflammatory Response
Eugenol has been investigated for its effects on biological pathways associated with inflammation.
Some experimental studies suggest that compounds in cloves may influence inflammatory processes. More high-quality human research is needed to determine whether ordinary dietary amounts produce meaningful anti-inflammatory benefits.
For everyday wellness, combine flavorful spices with regular physical activity, adequate sleep, and a balanced eating pattern.
How to use cloves: Add a small pinch of ground cloves to vegetable soups, roasted vegetables, or homemade spice blends.
6. Cloves May Contribute to Healthy Blood Sugar Management
Researchers have investigated clove-derived compounds for their possible effects on glucose metabolism and insulin-related pathways.
Some early laboratory and preliminary research findings are promising, but the evidence is not sufficient to establish cloves as a treatment for diabetes or to show that clove tea reliably lowers blood sugar in humans.
People with diabetes should continue following their prescribed treatment and monitoring plan.
How to use cloves: Add a small quantity of cloves to unsweetened tea, oatmeal, or other foods instead of adding extra sugar for flavor.
If you take medication to lower blood glucose, speak with your healthcare professional before using concentrated clove supplements regularly.
7. Cloves May Support Liver Health Research
Oxidative stress and inflammation are among the factors studied in relation to liver health. Because cloves contain antioxidant compounds, researchers have explored their potential effects in experimental models.
However, much of the relevant evidence comes from laboratory or animal studies. It does not establish that eating cloves detoxifies the liver, removes toxins, or treats liver disease.
The liver already performs essential detoxification functions. Maintaining a healthy weight, limiting alcohol, avoiding unnecessary supplements, and following medical advice are more established ways to protect liver health.
How to use cloves: Use modest amounts of whole or ground cloves as a culinary spice rather than taking concentrated extracts for a supposed liver cleanse.
8. Cloves May Help Freshen Breath
Cloves have a strong, pleasant aroma that can temporarily help mask unwanted breath odors.
Their compounds have also been investigated for antimicrobial activity, although the effects of consuming cloves on persistent bad breath have not been firmly established.
Bad breath can result from several causes, including dry mouth, gum disease, tooth decay, and certain medical conditions.
How to use cloves: Enjoy a lightly brewed clove infusion or use cloves in food. Brush twice daily with fluoride toothpaste, clean between your teeth, and stay hydrated.
If bad breath persists despite good oral hygiene, arrange a dental examination.
9. Cloves May Offer Benefits for Skin Research
The antioxidant and antimicrobial properties of clove-derived compounds have prompted research into potential skin-care applications.
However, evidence that cloves applied to the skin improve acne, reduce wrinkles, or treat skin infections is limited. Concentrated clove oil can cause irritation, allergic reactions, and chemical burns, especially when applied undiluted.
A safer approach: Obtain antioxidant-rich plant compounds primarily through a balanced diet and use skin-care products formulated and tested for their intended purpose.
Avoid homemade clove oil treatments on the face, particularly on sensitive skin or active acne lesions.
10. Cloves Add Flavor to a Healthy Lifestyle
One of the simplest benefits of cloves is their ability to make everyday foods more flavorful.
Their warm, slightly sweet taste works well with apples, pears, pumpkin, oats, rice dishes, soups, and many traditional spice blends.
Because cloves have an intense flavor, only a small amount is usually needed.
How to use cloves: Combine a pinch of ground cloves with cinnamon in oatmeal, or add one or two whole cloves to a pot of soup and remove them before serving.
Remember that cloves are best viewed as a flavorful culinary ingredient rather than a substitute for a balanced diet or medical care.
How to Use Cloves: 4 Simple Methods
Method 1: Clove Tea
Ingredients:
1–2 whole cloves
1 cup (240 ml) of water
A small slice of lemon, optional
Instructions:
Bring the water to a gentle boil.
Add the whole cloves.
Simmer for 5–10 minutes.
Strain the drink and allow it to cool slightly.
Add a slice of lemon if desired.
Enjoy it as an occasional warm beverage. There is no established medical dosage of clove tea for treating disease.
Method 2: Clove and Cinnamon Infusion
Ingredients:
1–2 whole cloves
A small piece of cinnamon stick
1 cup of water
Instructions:
Place the cloves and cinnamon in a small saucepan.
Add water and simmer for 5–10 minutes.
Strain before drinking.
This aromatic combination can be enjoyed without added sugar. It should not be regarded as a treatment for diabetes, high blood pressure, or digestive disease.
Method 3: Ground Cloves in Food
Add a small pinch of ground cloves to:
Oatmeal or overnight oats
Homemade applesauce
Pumpkin soup
Roasted vegetables
Homemade spice blends
Start with a small amount because the flavor can quickly overpower a dish.
Method 4: Whole Cloves in Cooking
Whole cloves are useful in soups, stews, broths, rice dishes, and marinades.
Add one or two cloves while cooking, then remove them before serving if desired. Whole cloves are hard and should not be swallowed accidentally, particularly by young children.
How Many Cloves Can You Use Per Day?
There is no universally established daily dose of cloves for health benefits.
For most healthy adults, using small culinary amounts in food is a reasonable approach. If you enjoy clove tea, begin with a lightly brewed preparation rather than a concentrated infusion.
The safety of regular medicinal use, high-dose extracts, and clove essential oil differs from that of ordinary culinary use.
More is not necessarily better, and there is no reliable evidence that consuming large quantities produces greater health benefits.
Important Precautions Before Using Cloves
Although cloves are commonly used as a spice, concentrated preparations require greater caution.
Blood-thinning medication: Eugenol may affect blood clotting. Ask your healthcare professional before using concentrated clove products if you take anticoagulants or antiplatelet medicines.
Surgery: Tell your healthcare team about supplements or concentrated herbal products you use before a planned procedure.
Liver health: Large amounts of clove oil can be toxic and may cause serious liver injury.
Pregnancy and breastfeeding: Culinary amounts are different from medicinal doses. Avoid concentrated clove preparations unless your healthcare professional advises otherwise.
Children: Never give children clove essential oil to swallow. Accidental ingestion can cause serious poisoning.
Allergies and irritation: Clove oil can irritate the skin and mouth and may trigger allergic reactions.
Diabetes medication: Do not use concentrated clove products to lower blood sugar without medical guidance.
Never drink clove essential oil or use it as a substitute for prescribed medication.
What Does Science Say About Cloves?
Cloves contain biologically active compounds, particularly eugenol, that have demonstrated antioxidant, antimicrobial, and other effects in laboratory studies.
However, the strength of the evidence varies by proposed benefit. Many claims about digestion, blood sugar, liver protection, inflammation, and disease prevention have not been confirmed by large, high-quality human clinical trials.
The most evidence-conscious way to enjoy cloves is to use them in normal culinary amounts as part of a varied, nutritious diet. Their potential benefits should not be exaggerated, and they should not be presented as a cure for chronic diseases.
Frequently Asked Questions
1. Is it good to drink clove water every day?
Small amounts of clove-infused water may be acceptable for many healthy adults, but there is limited evidence that daily consumption provides specific medical benefits. People taking medication or living with chronic conditions should seek professional advice before regular medicinal use.
2. Can cloves help with high blood sugar?
Clove compounds are being studied for their possible effects on glucose metabolism. Current evidence is insufficient to recommend cloves as a treatment for high blood sugar or diabetes.
3. Are cloves good for the kidneys?
There is no strong clinical evidence that cloves cleanse the kidneys, remove kidney stones, or treat kidney disease. People with kidney conditions should consult their healthcare professional before using concentrated herbal products.
4. Can cloves help with stomach problems?
Cloves have traditional uses related to digestion, but clinical evidence for treating specific stomach disorders is limited. Persistent or severe symptoms deserve medical evaluation.
