Can Chewing Cloves Help If You Have Diabetes?

Cloves are a small but remarkably aromatic spice commonly used in cooking, teas, and traditional wellness practices. Because cloves contain eugenol and other plant compounds with antioxidant activity, they have attracted interest among researchers studying glucose metabolism.

This has also led to viral claims suggesting that simply chewing a few cloves every day can “control diabetes” or even replace diabetes medication.

But there is an important distinction between traditional use, preliminary research, and proven diabetes treatment.

Some early research has found that certain clove extracts may influence blood glucose, but the available human evidence is still limited. One small pilot study involving 13 healthy or prediabetic volunteers found that a standardized water-soluble clove polyphenol extract was associated with reductions in fasting and post-meal glucose measurements. However, this was a small study of a specific extract—not evidence that chewing whole cloves treats diabetes.

So, can cloves be part of a healthy diet? Yes.

Can chewing cloves cure diabetes or replace prescribed treatment? No.

What Makes Cloves Interesting?

Cloves come from the dried flower buds of the clove tree, Syzygium aromaticum.

They contain several naturally occurring compounds, including:

• Eugenol
• Polyphenols
• Flavonoid compounds
• Volatile aromatic oils
• Other antioxidant compounds

Eugenol is one of the compounds responsible for cloves’ characteristic aroma and flavor.

Laboratory and animal research has investigated eugenol for its possible effects on glucose metabolism and oxidative stress. However, results from laboratory experiments or animal studies cannot automatically be translated into a proven treatment for people with diabetes.

1. Cloves May Support Healthy Glucose Metabolism

One reason cloves have attracted attention is their potential influence on glucose metabolism.

In a small human pilot study, participants consumed 250 mg of a water-soluble clove polyphenol extract once daily for 30 days. Researchers observed reductions in some fasting and post-meal glucose measurements.

However, the study had only 13 participants and did not test ordinary chewing of whole cloves. Therefore, more research is needed before specific amounts of cloves can be recommended for diabetes management.

This is an important point when interpreting social-media claims about cloves.

Clove extract studied in a clinical trial ≠ chewing whole cloves at home.

2. Cloves Provide Antioxidant Compounds

Oxidative stress is an area of interest in metabolic research.

Cloves are naturally rich in polyphenolic compounds, and laboratory research suggests that compounds found in cloves may have antioxidant properties.

Adding small amounts of culinary spices such as cloves to meals can therefore be an easy way to increase flavor without relying heavily on sugar or high-calorie sauces.

However, this should be viewed as part of an overall healthy eating pattern rather than a treatment for diabetes.

3. Cloves May Be Useful as a Flavorful Alternative to Sugar

This is one of the simplest practical benefits.

If you enjoy sweet beverages, adding spices such as cloves, cinnamon, ginger, or vanilla can provide a stronger flavor without adding much sugar.

For example, instead of preparing a heavily sweetened drink, you could make:

Warm Clove-Ginger Water

Ingredients

• 2–3 whole cloves
• 2–3 thin slices of fresh ginger
• 1½ cups water
• Optional: a squeeze of lemon

Preparation

1. Add the water, cloves, and ginger to a small saucepan.
2. Bring to a gentle simmer.
3. Simmer for approximately 5 minutes.
4. Turn off the heat and allow it to cool slightly.
5. Strain before drinking.
6. Add lemon if desired.

Do not add sugar or honey if you are trying to keep the drink low in added sugars.

This is a culinary beverage, not a diabetes treatment.

4. Can You Simply Chew Whole Cloves?

This is the idea shown in many viral posts.

Some people chew a small amount of whole cloves because of their strong flavor and traditional use. However, there is currently no established clinical dosage showing that chewing a specific number of whole cloves every day treats type 2 diabetes.

If you enjoy cloves, using them as a culinary spice is generally a more conservative approach than consuming concentrated clove oil or large quantities of clove powder.

And there is an important distinction:

Whole cloves are not the same as clove oil.

Clove oil is highly concentrated in eugenol. Large amounts of eugenol can be dangerous, and documented overdoses have caused serious toxicity, including liver injury.

Never drink clove essential oil as a homemade diabetes remedy.

5. What About Cloves and Insulin?

You may see claims online saying that cloves “increase insulin” or “reverse insulin resistance.”

The scientific picture is more complicated.

Laboratory studies have investigated clove compounds for effects on glucose uptake and pathways involved in glucose metabolism. Some experimental findings are interesting, but these results do not establish that eating cloves produces the same effect in people with diabetes.

The small human clove-extract study mentioned earlier provides preliminary evidence, but it is not enough to establish cloves as a diabetes treatment.

6. Cloves Should Not Replace Diabetes Medication

This is the most important message.

If you have lived with diabetes for 10 years, it is especially important not to stop prescribed medication because a social-media post recommends cloves or another natural remedy.

The National Center for Complementary and Integrative Health (NCCIH) notes that evidence for most dietary supplements used for diabetes is limited and advises people not to replace effective diabetes treatment with unproven products.

Diabetes management may involve:

• Medication
• Blood glucose monitoring
• Regular physical activity
• A balanced eating pattern
• Weight management when appropriate
• Regular medical checkups
• Monitoring of blood pressure and cholesterol
• Kidney and eye health monitoring

Cloves can potentially be one small culinary ingredient in that bigger picture, not the foundation of treatment.

7. Who Should Be Careful With Cloves?

Although cloves are commonly used as a food spice, concentrated preparations deserve more caution.

Talk with your healthcare professional before regularly using concentrated clove supplements if you:

• Take medication for diabetes
• Take blood-thinning medication
• Have liver disease
• Have kidney disease
• Have a bleeding disorder
• Are preparing for surgery
• Are considering concentrated herbal extracts

People with diabetes should also tell their healthcare provider about supplements and herbal products they use because interactions can occur between supplements and medicines.

8. What About Clove Powder?

Ground cloves can be incorporated into foods in small culinary amounts.

Try adding a small amount to:

• Oatmeal
• Unsweetened yogurt
• Chia pudding
• Herbal tea
• Homemade spice blends
• Roasted vegetables
• Soups
• Coffee or unsweetened beverages

The goal is to use cloves as a spice, rather than treating them like a medication.

9. A Simple Clove Recipe for a Low-Sugar Diet

Clove, Cinnamon & Ginger Infusion

Ingredients

• 2 whole cloves
• 1 small piece of fresh ginger
• 1 small cinnamon stick
• 2 cups water
• Lemon slice, optional

Directions

1. Place the cloves, ginger, and cinnamon in a saucepan.
2. Add 2 cups of water.
3. Simmer gently for 5–8 minutes.
4. Turn off the heat.
5. Let the drink cool slightly.
6. Strain into a cup.
7. Add lemon if desired.

There is no need to add sugar or honey.

Remember that this beverage is simply a flavorful, low-sugar option. It should not be presented as a treatment for diabetes.

What Does Science Actually Say About Cloves and Diabetes?

The evidence can be summarized simply:

The biggest limitation is that research on standardized extracts cannot simply be translated into a recommendation to chew a certain number of ordinary cloves every morning.

The Bottom Line

Cloves are an aromatic spice containing compounds such as eugenol and polyphenols that scientists are investigating for their possible effects on glucose metabolism and oxidative stress.

A small human pilot study found promising changes in glucose measurements after participants consumed a standardized clove extract, but the study was very small and does not prove that chewing cloves can control or cure diabetes.

If you enjoy cloves, using them in food or an unsweetened beverage can be a simple addition to a balanced diet.

But if you have diabetes—whether you’ve had it for 1 year or 10 years—don’t stop or change your prescribed medication because of a natural remedy circulating online. Current evidence does not support using cloves as a replacement for established diabetes treatment.

Think of cloves as a spice—not a cure.
