Cloves may look small, but they’re one of the most potent spices ever discovered. For centuries, these tiny dried flower buds have flavored dishes, soothed toothaches, supported digestion, and served as powerful natural remedies. Today, modern science is finally confirming what traditional healers have known for generations. This ultimate guide explores everything you need to know about cloves—including their benefits, how they work, how to use them safely, and why they belong in your daily life.
Before diving deeply into the science, let’s start with a quick personal story that often mirrors how many people first encounter cloves. I grew up seeing cloves in the kitchen mostly around the holidays. My family would simmer cloves with cinnamon sticks to make the house smell warm and comforting. When I got older, I learned that my grandmother used cloves for tooth discomfort, brewing them into teas to soothe digestion after large family dinners. It wasn’t until years later that I discovered just how much power was packed into those tiny buds. That curiosity led me to explore cloves far beyond cooking—and the more I learned, the more I realized how underrated this ancient spice truly is.
What Exactly Are Cloves?
Cloves are the dried, unopened flower buds of Syzygium aromaticum, an evergreen tree native to the Maluku Islands of Indonesia. These islands were once known as the “Spice Islands” because they produced some of the rarest and most valuable spices in the ancient world. Cloves were so coveted that they were traded like gold and drove early global exploration.
Today, cloves grow in several regions with tropical climates, including:
- Madagascar
- Zanzibar (Tanzania)
- Sri Lanka
- India
- Jamaica
The trees can reach up to 30 feet tall and produce clusters of crimson buds. Harvesters must carefully pick the buds by hand just before they bloom. Afterward, they’re sun-dried for several days until they harden and darken into the brown spice we recognize.
What makes cloves unique is that both the flavor and medicinal qualities come from a single dominant compound: eugenol.
The Secret Power of Cloves: Understanding Eugenol
The real reason cloves are so powerful lies in their chemical makeup—especially eugenol, which makes up 70–90% of clove essential oil.
What eugenol does inside the body:
- Provides natural pain-relief and numbing effects
- Acts as a strong antibacterial and antimicrobial agent
- Reduces inflammation
- Neutralizes free radicals as a potent antioxidant
- Helps protect tissues from oxidative stress
Because of these therapeutic properties, cloves have been deeply valued in:
- Ayurvedic medicine
- Traditional Chinese Medicine
- Middle Eastern herbal practices
- Ancient and modern dentistry
- Folk medicine worldwide
Even today, dentists still use eugenol in certain dental materials because of its soothing, antibacterial properties.
More human research is still needed, but current studies continue to produce highly promising results.
Top Health Benefits of Cloves
Below are the most widely researched and commonly cited benefits of cloves. They’re powerful, versatile, and supported by both tradition and modern science.
1. Cloves Relieve Toothaches and Support Oral Health
Cloves have a long-standing reputation for easing tooth pain. Eugenol provides both numbing and antiseptic effects, which makes it ideal for oral care.
How eugenol helps your mouth:
- Reduces gum inflammation
- Kills harmful bacteria that contribute to cavities
- Helps manage tooth pain temporarily
- Freshens breath naturally
How to use cloves for oral relief:
- Apply diluted clove oil on a cotton ball and place it gently near the painful tooth.
- Chew a whole clove to release numbing oils slowly.
- Look for oral-care products containing clove extract.
Important: Undiluted clove oil can cause burns—always dilute it in a carrier oil.
2. Cloves May Help Lower Blood Sugar
Early research suggests cloves may support blood sugar regulation, especially in individuals with prediabetes or type 2 diabetes.
Potential benefits include:
- Improving insulin sensitivity
- Supporting glucose control
- Reducing blood sugar spikes after meals
Animal studies have shown reductions in blood sugar levels with clove extract. While more human trials are needed, the evidence so far is encouraging.
Easy ways to add cloves for blood sugar support:
- Stir ground cloves into oatmeal
- Add to coffee or tea
- Blend into smoothies
- Sprinkle into baked goods or curries
Always check with a doctor if taking diabetes medication.
3. Cloves Support Liver Health
Your liver plays a major role in detoxification, digestion, and metabolism. Cloves contain antioxidants that may help protect liver tissue from oxidative damage.
Studies show cloves may:
- Lower liver inflammation
- Improve enzyme levels
- Help reduce fatty liver changes (in animal research)
While human studies are still evolving, the positive findings make cloves a promising addition to a liver-friendly diet.
4. Cloves Have Strong Antimicrobial & Antifungal Properties
Among all spices, cloves rank as one of the most powerful antimicrobial natural substances.
Cloves have been shown to fight:
- E. coli
- Salmonella
- Candida yeast
- Streptococcus mutans, a bacteria linked to cavities and plaque
Because of these properties, cloves can help support immune function and even act as a natural food preservative.
5. Cloves May Help Lower Blood Pressure
Cloves contain nutrients like potassium, along with eugenol, which may help relax blood vessels.
Potential cardiovascular benefits:
- Improved circulation
- Reduced arterial stiffness
- Lowered systolic blood pressure in some early studies
More research is needed, but the initial findings suggest cloves may contribute to heart health when used regularly in food.
6. Cloves Are Exceptionally High in Antioxidants
Cloves rank among the highest antioxidant foods known. Their ORAC score (a measurement of antioxidant capacity) is significantly higher than many fruits and vegetables.
Antioxidant benefits include:
- Reducing oxidative stress
- Supporting cellular health
- Slowing signs of aging
- Boosting overall wellness
Just one teaspoon of ground cloves provides a powerful antioxidant dose.
7. Cloves Support Digestion and Soothe the Gut
Traditional medicine systems have used cloves for centuries to support digestive comfort.
Digestion benefits may include:
- Reducing gas and bloating
- Easing nausea
- Supporting gut motility
- Enhancing digestive enzyme production
A simple clove tea after meals is a time-tested remedy for digestion.
