For years, I kept cloves and cinnamon in the same kitchen cabinet without ever thinking about what they had in common.
Cinnamon went into desserts and coffee. Cloves appeared around the holidays or in the occasional recipe. That was about it.
Then I started reading about their chemistry.
Cloves are exceptionally rich in eugenol, while cinnamon contains compounds such as cinnamaldehyde and polyphenols. Both spices have attracted scientific interest for their antioxidant activity and possible effects on inflammation, digestion, glucose metabolism, and microorganisms.
That’s when the combination became much more interesting.
Online, you’ll sometimes see claims that drinking cloves and cinnamon for several days causes an “irreversible” transformation in the body. That’s an exaggeration—but these two spices certainly contain biologically active compounds.
Here’s what may actually happen when you start using them together.
1. Your Body Gets a Concentrated Dose of Plant Compounds
Cloves may look tiny, but they’re remarkably rich in aromatic compounds.
Their characteristic smell comes largely from eugenol, a phenolic compound studied for antioxidant and antimicrobial properties.
Cinnamon brings another collection of plant chemicals, particularly cinnamaldehyde and various polyphenols.
Put the two into hot water and some of those aromatic compounds move into the drink—which explains its intense fragrance before you’ve even taken the first sip.
2. Something Interesting May Happen After Meals
Cinnamon has been extensively investigated for its relationship with blood glucose and insulin sensitivity.
Some clinical studies have found modest improvements in certain glucose measurements, although results vary considerably between studies and cinnamon isn’t a replacement for diabetes treatment.
Cloves have received less human research in this area, although laboratory studies have generated interest in their effects on glucose metabolism.
That’s one reason this combination frequently appears in after-meal herbal drinks.
3. Digestion May Feel Different
There’s a much simpler reason people have traditionally enjoyed aromatic spices after a heavy meal.
Warm liquids can feel soothing, while strongly flavored spices stimulate the senses and can make an after-dinner drink surprisingly satisfying.
Cloves have traditionally been used for digestive comfort, while cinnamon has a long culinary history alongside rich foods.
If the tea replaces a large sugary dessert or sweetened beverage, there’s another potential advantage that has nothing mysterious behind it.
4. Your Mouth Immediately Notices Eugenol
Bite into a whole clove and you’ll understand this one instantly.
Eugenol produces a distinctive warming and slightly numbing sensation. In fact, clove-derived eugenol has a long history in dentistry and remains familiar in dental applications.
That doesn’t mean clove tea can repair a cavity.
But it explains why generations of people associated cloves with the mouth and teeth—and why the sensation is so unmistakable.
5. The Combination Has Interesting Antioxidant Activity
Both spices contain compounds capable of interacting with reactive molecules in laboratory experiments.
That’s where the phrase “rich in antioxidants” comes from.
Antioxidants aren’t tiny scrub brushes traveling around the body “detoxing” organs. The body’s own antioxidant systems are far more complicated than that.
But regularly eating plant foods and spices rich in polyphenols can absolutely be part of a nutritious diet.
6. Cinnamon May Make Sweet Foods Taste Sweeter
This is one of the most practical tricks.
Cinnamon’s intense aroma can increase the impression of sweetness even when you haven’t added much sugar.
Add cloves and the flavor becomes even richer.
I’ve found this particularly useful in drinks where I’d previously have reached automatically for another spoonful of sugar.
Sometimes the health benefit isn’t something the spice adds.
It’s something it helps you use less of.
7. Your Evening Drink Becomes Naturally Caffeine-Free
Cloves and cinnamon contain no caffeine naturally.
So if you’re accustomed to having coffee or strong black tea late in the evening, switching occasionally to a cinnamon-clove infusion eliminates that dose of caffeine.
For someone sensitive to caffeine, that seemingly tiny change can make an evening routine considerably more sleep-friendly.
8. Researchers Are Interested in Their Antimicrobial Properties
Eugenol and cinnamaldehyde have both demonstrated antimicrobial activity in laboratory research.
This has generated considerable interest in their possible applications in food preservation and other areas.
But laboratory antimicrobial activity doesn’t mean drinking the tea “kills infections throughout the body.”
The human body is considerably more complicated than a laboratory dish.
Still, it’s another fascinating reason these two ancient spices remain subjects of modern research.
9. The Aroma Itself Can Become Part of a Relaxing Ritual
There’s something almost instantly comforting about cinnamon and cloves simmering together.
The aroma fills the kitchen before the drink is ready.
Prepare it at roughly the same time each evening, put your phone away, and spend ten minutes drinking it slowly, and you’ve created something surprisingly valuable:
a routine.
And consistent evening routines can be much more useful than chasing a different miracle drink every week.
10. But There’s One Cinnamon Detail Most People Never Hear About
Not all cinnamon is identical.
The inexpensive cinnamon commonly sold in supermarkets is often cassia cinnamon. Cassia can contain relatively high concentrations of coumarin, a naturally occurring compound.
Consuming large quantities of coumarin regularly can be harmful to the liver in susceptible people.
Ceylon cinnamon generally contains much less coumarin.
For occasional cooking this distinction isn’t usually dramatic. But if someone intends to drink cinnamon preparations frequently, using modest quantities—and considering Ceylon cinnamon—makes much more sense than swallowing spoonfuls of cinnamon powder every day.
11. Cloves Also Prove That “Natural” Can Be Powerful
Eugenol isn’t biologically meaningless simply because it comes from a spice.
Concentrated clove oil is dramatically stronger than the tiny amount extracted from a couple of whole cloves in tea. Large amounts of clove oil can be toxic and shouldn’t be swallowed casually as a wellness treatment.
There’s an enormous difference between seasoning food with cloves, making a mild infusion, and consuming concentrated essential oil.
The first two belong in the kitchen.
The last deserves considerably more caution.
12. So What Is the “Irreversible Reaction”?
This is where the viral headline gets ahead of the science.
There isn’t evidence that ordinary cinnamon-and-clove tea triggers some mysterious irreversible transformation after one week.
What can happen is much less dramatic but far more believable.
You introduce polyphenol-rich spices into your diet. You may replace a sugary beverage. You get a caffeine-free evening drink. Cinnamon may have modest metabolic effects in some people. And you establish a comforting routine that you’re likely to repeat.
Those changes don’t sound as spectacular as “IRREVERSIBLE BODY REACTION.”
But they’re much more useful.
My Warming Clove & Cinnamon Tea
This time I make it with a slightly different combination that gives the drink a naturally fruity flavor.
Ingredients
- 2 cups water
- 3 whole cloves
- ½ Ceylon cinnamon stick
- 2 thin slices of fresh apple
- 1 small strip of orange peel
- 1 lightly crushed green cardamom pod
- ½ teaspoon honey, optional
Preparation
Bring the water to a gentle boil.
Add the cinnamon, cloves and cardamom. Reduce the heat and simmer gently for approximately 5–7 minutes.
Turn off the heat and add the apple and orange peel.
Cover and allow everything to steep for another three minutes before straining.
Taste it before adding honey—the cinnamon, apple and orange create considerably more perceived sweetness than you’d expect.
Drink it warm after dinner or as a caffeine-free evening drink.
Don’t Make It Stronger and Stronger
This is where internet remedies often go sideways.
If three cloves taste pleasant, thirty aren’t going to produce ten times the benefits.
The same goes for cinnamon.
These are concentrated spices containing active plant chemicals, so culinary quantities are enough. This is especially important for people taking medicines that affect blood glucose or blood clotting, or anyone with liver disease.
And concentrated cinnamon or clove essential oils shouldn’t be substituted for the whole spices in this drink.
The Bottom Line
Cloves and cinnamon make a surprisingly interesting pair.
Cloves provide eugenol and other phenolic compounds, while cinnamon supplies cinnamaldehyde and polyphenols that researchers continue studying for their metabolic, antioxidant, and antimicrobial properties.
Used in normal culinary amounts, they can turn plain hot water into an intensely aromatic drink without caffeine or much sugar.
You probably won’t wake up on day seven with an irreversibly transformed body.
But you might discover something much easier to keep:
a simple nightly habit that tastes good enough that you actually want to continue it.
