Clove Water, Cinnamon Water, Turmeric Water… Do These Health Drinks Actually Work?

Why are these drinks so popular?

The basic idea is appealing. Take a familiar kitchen spice. Add hot water. Let it steep. Drink it every morning.

The drink then gets marketed as a natural way to:

• control blood sugar
• reduce inflammation
• improve digestion
• “detox” the body
• boost immunity
• burn fat
• improve liver health
• prevent disease

Some of these claims have a scientific starting point.

Cloves contain compounds such as eugenol. Cinnamon contains numerous polyphenolic compounds. Turmeric contains curcuminoids, including curcumin.

These compounds can produce interesting biological effects in laboratory studies and have been studied in humans.

But there’s a critical step that is often skipped:

Does the amount of these compounds that actually reaches the body from a cup of homemade spice water produce the same effect seen in a clinical study?

Usually, we don’t know.

The first problem: a spice is not the same as a spice supplement

This is probably the most important point in the entire article.

Imagine a clinical study gives participants 500 mg of a standardized curcumin formulation. You make turmeric water by adding a small amount of turmeric powder to hot water.

It would be tempting to say:

“Turmeric was shown to have this benefit.”

But that’s not necessarily what the study showed.

The same problem applies to cinnamon and cloves.

Water can extract some compounds from plant material, but not every compound dissolves equally well in water. And even when a compound enters the water, that doesn’t guarantee that it will be absorbed efficiently by the human digestive system.

This is particularly important for turmeric.

1. Turmeric water: the most interesting—and most misunderstood

Turmeric is probably the most heavily promoted of these three drinks. Its main compound of interest is curcumin.

Curcumin has been investigated for inflammation, osteoarthritis, metabolic health, liver-related outcomes and many other conditions. And there is a substantial amount of human research.

A 2024 systematic review and meta-analysis included 103 randomized controlled trials involving 7,216 participants and found statistically significant effects for some outcomes, including fasting blood glucose, inflammatory markers, HDL cholesterol and body weight. However, the certainty varied considerably between outcomes, and the authors emphasized the need for better long-term trials.

That sounds impressive. But there’s a catch.

Curcumin does not dissolve well in water. Poor water solubility is one of the major reasons conventional curcumin has low oral bioavailability.

Researchers have developed special formulations specifically to overcome this problem. For example, human pharmacokinetic studies have compared conventional curcumin with formulations designed to increase absorption. Some enhanced formulations produce dramatically higher blood exposure than ordinary curcumin.

This tells us something important: the amount of curcumin you consume isn’t the whole story. How it is formulated can substantially affect how much reaches the circulation.

What about turmeric as a food?

That’s a different question.

A human crossover study compared curcumin powder, turmeric powder and fresh turmeric consumed as part of a meal. The turmeric-containing meals produced higher plasma curcuminoid concentrations than isolated curcumin powder under the conditions tested.

But that still doesn’t prove that turmeric steeped in water delivers the same exposure as a clinical curcumin supplement. It doesn’t.

So does turmeric water reduce inflammation?

The answer: possibly in theory, but the evidence doesn’t establish that ordinary turmeric water is an effective anti-inflammatory treatment.

Human trials of turmeric and curcumin supplementation have reported reductions in some inflammatory markers. For example, a GRADE-assessed meta-analysis of 66 randomized controlled trials found reductions in CRP, TNF-α and IL-6 with turmeric/curcumin supplementation.

But this is where we need to be careful. A change in a blood biomarker does not automatically mean “you will feel healthier.” And a study using a concentrated supplement doesn’t automatically tell us what happens after drinking a weak homemade infusion.

A 2025 critical umbrella review also found potentially beneficial effects across several outcomes but noted that the methodological quality of the underlying meta-analyses was relatively poor.

2. Cinnamon water: does it really control blood sugar?

Cinnamon has a somewhat stronger case when it comes to metabolic research.

Researchers have conducted numerous randomized trials examining cinnamon supplementation and blood glucose.

An updated systematic review and dose-response meta-analysis of 24 randomized controlled trials in people with type 2 diabetes found statistically significant reductions in fasting blood sugar, HOMA-IR and HbA1c with cinnamon supplementation.

Another meta-analysis found reductions in fasting glucose but noted substantial heterogeneity between studies.

So there is a genuine scientific signal. But again: the studies generally used cinnamon supplementation—not necessarily a cup of cinnamon water. And that’s a big distinction.

Cinnamon water vs cinnamon supplement

Suppose a study gives participants a measured amount of cinnamon every day. The researchers know approximately:

• which cinnamon was used
• how much was consumed
• how long participants consumed it
• what outcomes were measured

Now compare that with homemade cinnamon water. The amount of cinnamon can vary. The species can vary. The extraction can vary. The amount actually consumed can vary. And the concentration of individual compounds isn’t necessarily standardized.

The NCCIH specifically notes that cinnamon research is difficult to interpret because studies don’t always clearly identify the species or part of the cinnamon plant being tested.

That’s not a minor detail. Cassia cinnamon and Ceylon cinnamon are chemically different. One major difference involves coumarin.

The coumarin issue

Cassia cinnamon can contain substantially more coumarin than Ceylon cinnamon.

Coumarin isn’t simply a “bad chemical.” The problem is that prolonged consumption of sufficiently large amounts of coumarin can be concerning for some people, particularly those with liver disease.

NCCIH notes that cinnamon is generally safe in amounts commonly used as a food spice, but larger amounts or prolonged use can cause problems, and some cassia products contain relatively high levels of coumarin.

This creates an important practical lesson:

More cinnamon is not automatically better. And turning a spice traditionally used in small culinary amounts into a concentrated daily “health drink” changes the exposure.

3. Clove water: what about blood sugar and digestion?

Clove may be the weakest of the three when it comes to human clinical evidence.

Cloves contain eugenol, along with other phytochemicals. Laboratory research has produced interesting findings involving antioxidant, antimicrobial, anti-inflammatory and metabolic pathways.

But laboratory activity is not the same as a proven health effect in humans.

There is at least some human evidence worth discussing.

A small open-label pilot study tested a water-soluble polyphenolic extract of clove buds in 13 otherwise healthy volunteers. Participants consumed 250 mg of the extract once daily for 30 days. The researchers reported reductions in some pre- and post-meal glucose measurements.

Interesting? Yes. Conclusive? No.

Why? Because the study was:

So we cannot take this study and conclude “drink clove water every morning to control blood sugar.” That leap goes far beyond the evidence.

What about clove water for digestion?

This claim is particularly common.

Clove is traditionally used in various cultures for digestive complaints. But traditional use is not the same as clinical proof.

The available human research does not establish that a homemade cup of clove water reliably improves digestion in healthy people.

And there is another important issue: clove oil is not the same thing as clove water.

Eugenol is highly concentrated in clove essential oil. Swallowing concentrated clove oil is completely different from drinking a mild infusion made from whole cloves.

High doses of eugenol can cause toxicity, and severe liver injury has been reported after high-dose ingestion of clove oil or eugenol. So “natural” should never be interpreted as “concentrated amounts are automatically safe.”

The “detox water” problem

This is where these drinks often become associated with another popular claim: “they detox your body.”

But what does “detox” actually mean?

Your body already has systems responsible for processing and eliminating many substances, including the liver, kidneys, lungs and gastrointestinal tract.

Drinking water can obviously contribute to hydration. Adding a spice may add flavor and small amounts of plant compounds.

But there is no good evidence that a daily cup of clove water, cinnamon water or turmeric water “flushes toxins” from the body in the way social-media detox claims imply.

A drink can contain biologically active compounds without being a detox treatment.

What about weight loss?

This is another common claim.

You’ll often see statements that cinnamon water or turmeric water:

• “melts belly fat”
• “boosts metabolism”
• “burns fat overnight”
• “detoxes fat from the liver”

The evidence does not justify those promises.

Some cinnamon supplementation studies have reported changes in glucose or certain metabolic markers, but that doesn’t mean cinnamon water causes meaningful weight loss.

For example, one systematic review found no significant effects of cinnamon supplementation on body weight or BMI despite effects on some glucose measures.

Similarly, turmeric and curcumin research has investigated body weight and metabolic markers, but the evidence is heterogeneous and largely concerns supplementation rather than homemade turmeric water.

Verdict: there is no good evidence that these drinks are fat-burning beverages.

What about “anti-inflammatory” drinks?

This claim requires another important distinction.

A compound can demonstrate anti-inflammatory activity at very different levels of evidence:

1. In a test tube
2. In an animal
3. In a human blood biomarker
4. In symptoms
5. In a clinical outcome

These are not interchangeable.

Curcumin, for example, has substantial mechanistic research behind it. Human trials also exist. But the fact that curcumin can influence inflammatory markers doesn’t mean a cup of turmeric water will treat an inflammatory disease.

That’s why evidence-based nutrition needs to ask what was actually tested—not simply, does this plant contain an interesting compound?

Why water changes the story

Here’s the hidden problem with most online “spice water” claims.

A recipe might say: add one teaspoon of turmeric to hot water. But scientific research doesn’t necessarily study that preparation.

What researchers may have used	Standardized extract → known concentration → controlled dose → specific formulation → measured outcome
What your kitchen version may be	Variable amount → variable extraction → variable concentration → unknown bioavailability

This doesn’t mean homemade spice drinks are useless. It means we shouldn’t promise a clinical effect that hasn’t actually been demonstrated.

A better way to think about these drinks

Instead of asking “does turmeric water work?” ask:

1. What compound are we interested in? Turmeric → curcuminoids. Clove → eugenol and polyphenols. Cinnamon → numerous polyphenolic and aromatic compounds.
2. Was that compound actually tested in humans? Sometimes yes.
3. What form was tested? Food, powder, tea, extract, capsule, standardized supplement or enhanced formulation? This is crucial.
4. Was the amount comparable? Often we don’t know.
5. Was the outcome clinically meaningful? A change in a biomarker isn’t automatically a meaningful health outcome.

This five-step approach prevents a huge amount of nutrition misinformation.

So which one “works” best?

If we compare the evidence rather than the internet hype:

Drink	Human evidence	What looks promising	Main problem
Turmeric water	Moderate, for some turmeric/curcumin preparations	Inflammatory and metabolic markers	Most research isn’t on ordinary turmeric water; curcumin has poor water solubility
Cinnamon water	Moderate, for cinnamon supplementation and some glucose measures	Fasting glucose and some metabolic markers	Species, dose and preparation vary; evidence remains inconsistent
Clove water	Limited	Preliminary glucose findings from a small extract study	Very little direct evidence for homemade clove water
All three as “detox drinks”	No convincing evidence	Hydration and flavor	“Detox” claims aren’t supported

The most important difference: food vs supplement

There’s nothing inherently wrong with using these spices in food. In fact, that’s probably the simplest way to think about them.

Turmeric can add flavor and color. Cinnamon can replace some added sugar in certain foods. Cloves can contribute flavor and aroma. And spices can make nutrient-dense meals more enjoyable.

The problem begins when we turn a culinary ingredient into a quasi-medical treatment without evidence that the preparation actually delivers the studied dose.

What about drinking them every day?

For ordinary culinary quantities, these spices are generally used safely by many people.

But “every day” becomes a different question when someone is consuming concentrated preparations.

Cinnamon

NCCIH says cinnamon is likely safe in amounts commonly used in food, while larger or prolonged amounts can cause gastrointestinal or allergic effects. Cassia cinnamon’s coumarin content can also be relevant, particularly for people with liver disease.

Turmeric

NCCIH notes that conventional oral turmeric is likely safe for most people in recommended amounts for up to a few months, but gastrointestinal effects can occur. More importantly, some high-bioavailability curcumin products have been associated with liver injury.

This does not mean ordinary culinary turmeric is dangerous. It means concentrated supplements and specially formulated products shouldn’t automatically be treated as equivalent to food.

Clove

Whole cloves used as a culinary spice are very different from concentrated clove oil. High-dose eugenol or clove-oil ingestion can be toxic, including serious liver injury after overdose.

“Natural” doesn’t mean “dose doesn’t matter”

This may be the most useful takeaway.

Many people assume: natural → safe → more is better.

Nutrition doesn’t work that way. A plant can contain compounds that are useful at one exposure and problematic at another.

The biological effect depends on dose × preparation × duration × absorption × individual factors.

That’s why clinical research measures doses rather than simply asking whether a plant is “healthy.”

Should you drink these health drinks?

If you enjoy them as flavored beverages, there’s little reason to treat them as forbidden.

But don’t expect a cup of spice water to replace:

• a balanced diet
• adequate protein
• fruits and vegetables
• physical activity
• sleep
• medical treatment
• medication when prescribed

And don’t use them as a substitute for treatment of diabetes, liver disease, arthritis or other medical conditions.

A reasonable way to view them:

Turmeric water	A flavorful drink containing turmeric compounds, but not a proven anti-inflammatory treatment.
Cinnamon water	A flavorful way to consume cinnamon, with some interesting glucose research—but not a replacement for diabetes treatment.
Clove water	A flavorful clove infusion with limited direct clinical evidence—not a proven detox or blood-sugar therapy.
