Clove water, made by steeping whole or ground cloves in water, delivers a concentrated dose of antioxidants and a notable amount of manganese. It’s a low-calorie way to get some genuine health benefits, though many of the bold claims you’ll find online outpace the actual evidence. Here’s what holds up and what doesn’t.
What You Actually Get From Clove Water
A single teaspoon (2 grams) of ground cloves packs 55% of your daily manganese needs, a mineral essential for bone health, blood clotting, and metabolism. It also provides a small amount of vitamin K and about 1 gram of fiber, all for just 6 calories. When you steep cloves in hot water, some of those nutrients dissolve into the liquid, though fiber and fat-soluble compounds stay behind in the clove material itself.
The star compound in cloves is eugenol, a plant-based phenol that gives cloves their distinctive warm, spicy smell. Eugenol is the main bioactive compound in cloves and is widely used in the pharmaceutical industry for its antioxidant, anti-inflammatory, and antimicrobial properties. When you steep cloves in water, eugenol partially dissolves into the liquid, along with other phenolic compounds that help neutralize free radicals in the body.
Antioxidant and Anti-Inflammatory Effects
Cloves rank among the most antioxidant-rich spices available. Their phenolic compounds work by scavenging free radicals, the unstable molecules that contribute to cell damage, aging, and chronic disease over time. Regularly consuming antioxidant-rich foods is linked to lower rates of heart disease, certain cancers, and neurodegenerative conditions.
The eugenol in cloves also has documented anti-inflammatory activity. Chronic low-grade inflammation is a driver behind conditions like type 2 diabetes, heart disease, and arthritis. While drinking clove water isn’t a substitute for medical treatment, incorporating it as part of a diet already rich in fruits, vegetables, and whole grains adds to your overall antioxidant intake in a meaningful way.
Blood Sugar: Promising but Preliminary
Some of the most interesting research on cloves involves blood sugar regulation. Compounds called triterpenes, found naturally in cloves, appear to slow how quickly sugar is absorbed in the gut. In diabetic rats, these compounds significantly reduced blood glucose levels after a carbohydrate-heavy meal. The mechanism is specific: they inhibit the enzymes that break down starches (like amylase and glucosidase) and reduce the activity of glucose transporters in the small intestine, meaning less sugar enters the bloodstream at once.
In one study, clove-derived compounds performed comparably to acarbose, a prescription drug used to manage post-meal blood sugar spikes, based on how effectively they inhibited these enzymes. That’s noteworthy, but it’s important to recognize that these results come from animal studies using isolated compounds at controlled doses, not from people drinking clove water at home. The direction of the evidence is encouraging, but human trials are still needed to confirm whether a daily cup of clove water produces a measurable effect on blood sugar.
Oral Health and Digestion
Cloves have been used for centuries as a remedy for toothaches, and eugenol is still an active ingredient in some dental products. Its mild numbing and antibacterial properties can temporarily ease tooth pain and reduce bacteria in the mouth. Swishing clove water isn’t equivalent to a clinical mouthwash, but it’s not without basis either.
For digestion, the picture is less clear. Clove water is commonly promoted as a remedy for bloating, gas, and indigestion. While cloves do have properties that could theoretically stimulate digestive processes, WebMD notes there is “no good scientific evidence” to support most of these traditional uses. Some people report that warm clove water settles their stomach, which may simply reflect the general soothing effect of warm liquids on the digestive tract. It’s unlikely to cause harm, but treat digestive claims with healthy skepticism.
How to Make It
The simplest method is to add 3 to 5 whole cloves (or about half a teaspoon of ground cloves) to a cup of hot water and let them steep for 10 to 15 minutes. Longer steeping extracts more bioactive compounds. Research on industrial extraction shows that higher temperatures and longer contact times consistently pull more eugenol and polyphenols from clove material, so using boiling or near-boiling water and steeping on the longer side will give you a more potent drink.
You can strain the cloves out or leave them in. Some people add honey, lemon, or cinnamon to round out the flavor. One or two cups per day is a reasonable amount. The taste is strong and warming, so you may want to start with fewer cloves and adjust.
Who Should Be Careful
Eugenol is an inhibitor of platelet activity, meaning it can slow blood clotting. If you take blood-thinning medications like warfarin, regular consumption of clove water could amplify those effects and increase your bleeding risk. This interaction is well-documented enough that clinical monitoring is recommended for people who use clove products extensively while on anticoagulants or similar medications.
In large amounts, eugenol can also irritate the mouth, throat, and digestive lining. Sticking to culinary quantities, a few cloves steeped in water rather than concentrated clove oil, keeps you well within safe territory. Pregnant or breastfeeding women may want to limit intake to normal food amounts, as concentrated clove preparations haven’t been well studied in those populations.
For most people, a daily cup of clove water is a safe, low-effort addition to your routine. It won’t replace a balanced diet or targeted medical treatment, but the antioxidant load is real, the manganese content is significant, and the potential blood sugar benefits are worth watching as more research develops.
