Introduction
Cloves (Syzygium aromaticum) are more than just a fragrant spice you might find in pumpkin pie or mulled cider. For centuries, they have been valued in traditional medicine across Asia, the Middle East, and Europe. In recent years, people in the United States have become increasingly interested in how everyday herbs like cloves can support wellness naturally. But beyond their warm flavor, what does science say about cloves?
This article offers an evidence-based guide to cloves—their health benefits, possible side effects, safe uses, and everyday applications like clove water. Whether you’re curious about digestion, oral health, women’s wellness, or simple home remedies, here’s what you need to know.
What Are Cloves?
Cloves are dried flower buds of the clove tree, native to Indonesia. They contain essential oils, with eugenol being the primary active compound. Eugenol has been extensively studied for its antimicrobial, anti-inflammatory, and antioxidant properties.
Nutritionally, cloves are a source of:
Vitamins: C, K, and trace amounts of B vitamins
Minerals: manganese, calcium, and magnesium
Bioactive compounds: flavonoids and phenolic acids
Health Benefits of Cloves
1. Digestive Support
Cloves have long been used to ease indigestion and bloating. Modern research shows that eugenol stimulates digestive enzymes and reduces gas formation. Drinking clove tea or adding cloves to meals may support gut comfort.
2. Oral Health
Dentists have historically used clove oil for toothaches. Today, clove-based gels are sometimes used for temporary relief from dental pain. A study published in Journal of Dentistry (2022) found that clove extract had antimicrobial effects against bacteria that cause gum disease.
3. Antioxidant & Anti-inflammatory Effects
Cloves are one of the richest dietary sources of antioxidants. These compounds neutralize free radicals, lowering oxidative stress—a factor linked to heart disease, diabetes, and aging.
4. Blood Sugar Management
Several small clinical trials suggest that clove extract can improve insulin sensitivity and glucose control in people with type 2 diabetes. While not a replacement for medication, cloves may be a useful addition to a balanced diet.
5. Heart and Liver Protection
Animal studies show that eugenol may help lower cholesterol and reduce liver inflammation. Though human evidence is limited, preliminary results are promising.
Benefits of Cloves for Women
Women often ask how cloves affect the female body. While research is still emerging, possible benefits include:
Menstrual relief: Eugenol’s mild analgesic properties may help ease cramps.
Bone health: Early studies suggest clove compounds may support bone density, which is important during menopause.
Skin and antioxidant protection: Antioxidants in cloves may support skin health during hormonal changes.
⚠️ Pregnancy note: While cloves in food are safe, concentrated oils or supplements should be avoided due to potential uterine stimulation.
Everyday Uses of Cloves
Clove Water
A popular way to use cloves is by soaking a few buds overnight in water. Drinking this infusion in the morning may support digestion, hydration, and antioxidant intake.
How to make clove water:
Add 2–3 whole cloves to a glass of water.
Let soak overnight (6–8 hours).
Drink in the morning on an empty stomach.
Culinary Uses
In the U.S., cloves are often used in baked goods, stews, and holiday recipes. Beyond flavor, culinary use ensures you enjoy cloves in safe, moderate amounts.
Aromatherapy & Topical Oil
Clove essential oil is used in aromatherapy for its warm scent. Diluted oil may also be applied to sore muscles, though it should always be patch-tested to avoid irritation.
What Happens If You Consume Cloves Every Day?
Small amounts of cloves—such as in food or clove water—are generally safe and may provide steady antioxidant and digestive benefits. However, daily use of clove oil or large doses of clove supplements can cause side effects, including liver stress and gastrointestinal discomfort.
Can Cloves Help With Weight Loss?
There is no evidence that cloves directly burn fat. However, they may play a supportive role by:
Reducing bloating
Supporting healthy digestion
Helping regulate blood sugar, which may reduce sugar cravings
Weight loss ultimately depends on overall diet and lifestyle, not a single herb.
What Is the Best Time to Take Cloves?
Morning: Clove water or tea may boost digestion and energy.
After meals: Helps reduce gas and bloating.
Evening: Some people prefer clove tea for relaxation, but the strong flavor may be stimulating for sensitive sleepers.
Side Effects and Risks of Cloves
Common Risks
Liver toxicity: High doses of eugenol can stress the liver.
Allergic reactions: Possible in sensitive individuals.
Blood thinning: Cloves may interact with anticoagulant medications (e.g., warfarin).
Special Considerations
Pregnancy: Culinary use is safe; avoid oils/supplements.
Children: Never give clove oil directly to children due to toxicity risk.
Kidney health: Food amounts are safe, but those with chronic kidney disease should consult a doctor before using concentrated clove products.
What Diseases Are Cloves Traditionally Used For?
Historically, cloves were used in Ayurveda and Chinese medicine to support:
Infections and respiratory conditions
Toothaches and gum pain
Digestive problems
Modern science is now exploring these uses in controlled studies, though cloves should not be seen as a cure for any disease.
Frequently Asked Questions

Conclusion
Cloves are more than a holiday spice—they offer a unique blend of antioxidants, anti-inflammatory compounds, and potential health benefits. From digestive support to oral health, cloves have a long history of use backed by growing scientific research.
For most Americans, adding cloves to meals or drinking clove water occasionally can be a safe, natural way to enhance wellness. However, as with any herb, moderation is key, and those with medical conditions should consult a healthcare provider before starting regular use.
Cloves remind us that sometimes, the simplest ingredients in the kitchen can also offer the most powerful health support.
