The Short Answer: Clove Water Alone Won't Lower Your Blood Pressure

Clove water—hot water steeped with whole cloves or clove powder—contains compounds that show promise in laboratory studies, but drinking it will not lower your blood pressure on its own. Some research suggests cloves may have mild blood-pressure-related effects, but the studies are small, often done in animals or test tubes, and the amounts used are much larger than what you'd get from a cup of clove water. If you have high blood pressure, clove water might be a pleasant addition to your routine, but it should never replace medication or the lifestyle changes that actually work.

The bottom line: clove water is safe for most people to drink, but the evidence that it lowers blood pressure in humans is too weak to rely on. If you want to try it, do so only alongside your current treatment plan and with your doctor's knowledge.

Key Takeaways

  • Cloves contain compounds called eugenol and flavonoids that affect blood vessels in laboratory settings, but human studies are too small to prove clove water lowers blood pressure.
  • The amount of active compounds in a cup of clove water is far lower than the doses tested in research studies.
  • Blood pressure control depends on medication (if prescribed), salt reduction, regular movement, weight management, and stress reduction—not herbal drinks.
  • Clove water is safe for most people in normal amounts, but it can interact with blood thinners and may irritate the stomach if you drink it on an empty stomach.
  • If you want to try clove water alongside your current treatment plan, talk to your doctor first, especially if you take blood pressure medication.

What the Research Actually Shows About Cloves

Cloves contain eugenol, a compound that relaxes blood vessel walls in test-tube and animal studies. When blood vessels relax, they widen slightly, which can lower the pressure inside them. Cloves also hold flavonoids, plant chemicals with anti-inflammatory properties. In theory, reducing inflammation might help blood pressure, since chronic inflammation is linked to high blood pressure in some people.

However, the human evidence is thin. A small 2015 study published in the journal Nutrition found that people who took clove powder supplements (not clove water) for eight weeks showed a modest drop in blood pressure compared to a placebo group. But the study involved only 60 people, lasted just eight weeks, and used a concentrated supplement—not a home-brewed drink. Most other human studies on cloves and blood pressure are similarly small or focus on other health outcomes.

The gap between lab results and real life is large. A cup of clove water contains far less eugenol and flavonoids than the doses used in research. You would need to drink clove water multiple times daily for weeks to approach the amounts tested, and even then, the effect would likely be small. No large, well-designed human study has shown that clove water specifically lowers blood pressure in people who drink it regularly.

How Much Clove Is Actually in Your Cup

A typical cup of clove water uses three to five whole cloves or one-quarter teaspoon of ground cloves steeped in hot water for five to ten minutes. This produces a mild, slightly sweet flavor. The eugenol content in that cup is roughly 5 to 15 milligrams, depending on how many cloves you use and how long you steep them.

The 2015 study mentioned above used 250 milligrams of clove powder per dose—roughly 15 to 50 times what you'd get in a single cup of clove water. To match the study dose, you would need to drink many cups daily or switch to a concentrated supplement. Even then, the blood pressure drop observed in that study was modest: about 3 to 4 millimeters of mercury, which is smaller than the drop most people see from a single dose of blood pressure medication. This means you would be consuming a large amount of clove to achieve a small, uncertain effect.

What Actually Lowers Blood Pressure

If you have high blood pressure, the evidence for what works is much stronger than the evidence for clove water. Medication prescribed by your doctor is the first line of treatment for most people. Common classes include ACE inhibitors, beta-blockers, calcium channel blockers, and diuretics. These drugs lower blood pressure by 10 to 20 millimeters of mercury or more.

Lifestyle changes matter just as much. Reducing salt intake to under 2,300 milligrams per day (about one teaspoon) can lower blood pressure by 5 to 6 millimeters of mercury. Regular physical activity—150 minutes of moderate exercise per week—can lower it by 5 to 8 millimeters. Losing weight if you are overweight, limiting alcohol, managing stress, and eating a diet rich in vegetables and low in processed foods all have solid research behind them. These changes work together and often reduce the amount of medication you need.

Clove water fits nowhere in this list. It is not a substitute for any of these proven approaches. If you enjoy the taste and want to drink it as part of a healthy routine, that is fine—but do not skip your medication or delay lifestyle changes because you are drinking clove water.

Is Clove Water Safe to Drink Regularly

For most people, clove water in normal amounts is safe. Cloves have been used in cooking and traditional medicine for centuries without serious harm. However, a few cautions explore. Clove oil and clove powder are much more concentrated than clove water and can cause mouth and throat irritation or stomach upset if taken in large amounts. Stick to whole cloves or a small amount of powder steeped in water, not clove oil.

If you take blood thinners like warfarin or aspirin, talk to your doctor before drinking clove water regularly. Eugenol has mild anticoagulant properties, meaning it may slightly thin your blood. Combined with medication, this could increase bleeding risk. Similarly, if you have a bleeding disorder or are scheduled for surgery, mention clove water to your healthcare provider. Clove water may also irritate your stomach if you drink it on an empty stomach, especially if you have acid reflux or a sensitive digestive system. Drink it after a meal or with food instead.

Pregnant women should avoid large amounts of clove, though occasional clove water is generally considered safe—ask your doctor if you are unsure. Children can drink clove water in small amounts, but it is not necessary for their health and should not replace proven treatments for any condition.

How to Make Clove Water If You Want to Try It

If you decide to try clove water as part of your daily routine (alongside your prescribed treatment), here is how to make it straightforward. Boil eight ounces of water and add three to five whole cloves. Let them steep for five to ten minutes—longer steeping makes a stronger flavor. Strain out the cloves and drink the water warm or let it cool. You can add a small amount of honey or lemon if you like.

Alternatively, use one-quarter teaspoon of ground clove powder per cup of hot water, stir well, and drink after it cools slightly. Ground clove settles to the bottom, so stir before each sip or strain through a fine mesh if you prefer not to drink the powder particles. Make clove water fresh each time rather than storing it, since the active compounds break down over time. Drink it once or twice daily if you enjoy it, but do not expect it to replace your blood pressure medication or lifestyle changes.

Frequently Asked Questions

Can I drink clove water instead of taking blood pressure medication?

No. Clove water has not been proven to lower blood pressure in humans, and the amount of active compounds in a cup is too small to have a measurable effect. If your doctor prescribed blood pressure medication, continue taking it as directed. Stopping medication without medical guidance can lead to serious complications like heart attack or stroke.

How long does it take for clove water to work?

There is no evidence that clove water works to lower blood pressure at all, even over weeks or months. The small human study on clove powder showed results after eight weeks, but that used a much larger dose than clove water provides. Do not wait to see if clove water is working—rely on your medication and the lifestyle changes your doctor recommends.

Is clove water better than other herbal drinks for blood pressure?

Other herbal drinks like hibiscus tea and green tea have slightly stronger research behind them for blood pressure, though the effects are still modest. Hibiscus tea in particular shows more consistent results in human studies than clove water does. However, none of these drinks should replace medication or lifestyle changes. If you are interested in herbal options, discuss them with your doctor.

Can I drink clove water if I am already on blood pressure medication?

Clove water is generally safe alongside blood pressure medication for most people. However, if you take blood thinners or have a bleeding disorder, check with your doctor first because eugenol has mild anticoagulant effects. Also mention it if you take other medications, since cloves may interact with certain drugs.

What should I do if clove water upsets my stomach?

Stop drinking it or drink it only after meals. Cloves can irritate the stomach lining, especially on an empty stomach. If stomach upset continues, clove water is not right for you. There is no reason to push through discomfort for a drink with unproven blood pressure benefits.
