You’ve probably tossed a few cloves into a recipe or a warm drink without thinking much about them. They add a nice flavor, right? But cloves aren’t just a tasty spice — they’re packed with surprising health perks. In this guide, we’ll explore the benefits of cloves, how they affect the body, any side effects to watch out for, and easy ways to start using them more often.
The Life Cycle of a Clove Plant

If you’ve ever noticed that whole cloves look like tiny flower buds, it’s because that’s exactly what they are — the unopened flower buds of the clove tree, Syzygium aromaticum. Native to Indonesia’s Maluku Islands, this evergreen tree now grows in tropical regions across the globe. Clove trees thrive in warm climates with fertile, well-drained soil and consistent rainfall. Reaching heights of up to 30 feet, they produce aromatic crimson buds, which are carefully harvested by hand just before they bloom. These buds are then sun-dried until they develop the deep reddish-brown color most people recognize. Depending on the drying method, this process can take several days to a few weeks.
Unlocking the Secrets of Clove Power

Black cloves contain a powerful compound you may not be familiar with — eugenol. This natural substance is known for its strong anti-inflammatory and antibacterial properties, and it has been a staple in traditional Chinese and Ayurvedic medicine for centuries. While more modern scientific research is needed to fully uncover how cloves impact our health, their potential is undeniable. This tiny spice packs a punch. Here are some of the possible health benefits of cloves:
Clove Power for a Healthier Mouth
Eugenol, the key compound found in cloves, is a potent antibacterial agent that can help reduce harmful bacteria in the mouth — the kind that contribute to plaque buildup, cavities, and gum disease. For centuries, cloves have been valued for their natural ability to relieve tooth pain and support gum health. These benefits can be accessed through clove-based herbal mouthwashes or by applying clove oil directly to the affected area. However, it’s important to use clove oil sparingly and avoid swallowing it. When used properly, cloves may provide a natural, effective way to ease toothaches and reduce gum inflammation. That said, if you’re experiencing ongoing tooth pain, bleeding gums, or jaw discomfort, it’s essential to consult your dentist for a proper diagnosis and treatment.
Can Cloves Help Control Blood Sugar?

If high blood sugar runs in your family, cloves might offer a natural way to support healthy glucose levels — potentially reducing reliance on medication. Emerging research suggests that eugenol, the active compound in cloves, may enhance insulin sensitivity, which in turn can help lower blood sugar. While these findings are promising, it’s crucial for individuals with diabetes or prediabetes to follow their doctor’s guidance.
Cloves are not a substitute for prescribed treatments, and combining them with blood sugar medications without medical advice could be risky. The safest way to enjoy the potential benefits is by including cloves in a balanced diet — such as adding them to meals or warm beverages. However, if you’re considering taking cloves in concentrated forms (like supplements or oils), always consult your healthcare provider first to avoid interactions or unintended side effects.
How Cloves May Help Regulate Blood Pressure
In addition to supporting healthy blood sugar levels, cloves may also help lower blood pressure. Studies suggest that eugenol and other compounds in cloves have vasodilatory properties, meaning they can help relax and widen blood vessels, which may lead to reduced blood pressure. Cloves are also rich in antioxidants that combat oxidative stress and inflammation—both key contributors to hypertension. Some research indicates that adding cloves to your diet or using clove oil in aromatherapy could promote cardiovascular health and help maintain healthy blood pressure. However, cloves should never replace prescribed blood pressure medications. If you’re currently taking medication, it’s important to consult your doctor before using cloves or any natural remedies to manage your blood pressure.
Investigating Eugenol’s Anti-Cancer Properties

Eugenol, a potent antioxidant and anti-inflammatory compound found in cloves, shows promising potential as an anti-cancer agent. Some studies suggest that the bioactive substances in cloves may help slow the growth of cancer cells and even trigger their death in certain types of cancer. However, more research is needed to fully understand how these effects work. Adding cloves to a balanced, healthy diet might provide some extra protection against cancer, but it’s important to remember that cloves are not a substitute for conventional cancer treatments. Always consult with a healthcare professional before using cloves for cancer prevention, especially if considering high doses or concentrated forms.
Using Cloves to Alleviate Skin Irritation

In traditional medicine, cloves—especially clove oil—have long been used to ease itchy skin thanks to their natural analgesic and anti-inflammatory effects. The key compound behind these benefits is eugenol, which helps soothe irritation and discomfort. To safely use clove oil on your skin, dilute it with a carrier oil like coconut or olive oil before applying it to the affected area. It’s important to perform a patch test first to rule out any allergic reactions, since natural doesn’t always mean risk-free. If you have sensitive skin or any existing skin conditions, consulting a dermatologist or healthcare professional before use is highly recommended to ensure it’s safe and won’t aggravate your symptoms.
Using Cloves to Promote Clearer Breathing

If you’re struggling with breathing due to phlegm buildup—common after colds or flu—steam inhalation with cloves may provide relief. The eugenol and other aromatic compounds in cloves have long been used for their healing effects on the respiratory system. Clove-infused steam can help open airways, soothe sore throats, and reduce congestion caused by colds, bronchitis, or allergies. It works by loosening mucus, making it easier to breathe. To try this at home, simply add a few whole cloves or a few drops of clove oil to a bowl of hot water. Lean over the bowl, cover your head with a towel to trap the steam, and breathe deeply. Be careful that the steam isn’t too hot to avoid burns. If you have existing respiratory issues or sensitivities, it’s best to check with your healthcare provider before trying this remedy.
Spice Up Your Slimming Journey with Cloves

Compounds in cloves, such as eugenol and other antioxidants, have shown potential to boost metabolism and support fat burning, which could be helpful for those aiming to lose weight. Additionally, cloves’ blood sugar regulation and anti-inflammatory effects play important roles in weight management. However, simply adding cloves to your diet or taking supplements won’t cause fat to melt away on their own. Cloves should be viewed as a complement to a healthy lifestyle that includes balanced nutrition, quality sleep, stress management, and regular exercise. If you’re having trouble losing weight, it’s best to consult a healthcare professional, dietitian, or qualified fitness expert. Together, you can identify the obstacles and create a plan tailored to help you become your healthiest self.
Cloves and Their Effectiveness Against Parasites

In traditional medicine, cloves have been used as a natural remedy to help eliminate parasites from the digestive tract. The eugenol and other volatile oils in cloves are believed to possess anti-parasitic properties, which is why they have been employed for this purpose. Some studies indicate that these compounds may inhibit the growth of certain parasites, alongside their well-known anti-inflammatory and antimicrobial effects. However, it’s important to understand that while cloves show promise, the scientific evidence supporting their effectiveness as a standalone treatment against parasites is still limited. It’s always best to consult with your healthcare provider to determine the most appropriate treatment plan for digestive parasites.
Exploring Cloves as a Natural Bed Bug Remedy

Dealing with bed bug infestations can be tough, and eliminating them is often challenging. Cloves have been suggested as a natural repellent because of their strong scent and possible insecticidal properties. Some people use whole cloves or sachets filled with cloves placed around infested areas to help keep bed bugs away, while others make sprays by adding drops of clove essential oil to water. However, there’s no solid evidence that cloves can fully eliminate a bed bug infestation or provide a long-term solution. For serious infestations, it’s best to consult a professional pest control service to ensure effective and lasting removal.
Potential Side Effects of Cloves
Just because something is natural doesn’t mean it can’t be dangerous. Cloves, although a common ingredient, are no exception. There are potential risks and side effects to keep in mind, especially if you plan to consume cloves in large amounts. Clove oil can be toxic if ingested, particularly for children, and may cause liver damage or seizures. People who are pregnant, breastfeeding, taking blood thinners, preparing for surgery, or managing diabetes with insulin should avoid excessive use of clove products. That said, using cloves as a flavoring in baked goods, savory meals, or warm drinks is generally safe. However, supplements or highly concentrated clove products should be used with caution or avoided altogether.
Cloves and Pregnancy: What You Should Know

There is a common belief that consuming large amounts of cloves early in pregnancy might cause miscarriage due to eugenol, a compound thought to stimulate the uterus. However, there isn’t enough scientific evidence to support this claim. Using small amounts of clove spice in cooking, baking, teas, and other foods is generally considered safe for pregnant women and their babies. While it’s wise to consume spices, including cloves, in moderation during pregnancy, typical culinary use doesn’t pose a significant risk of miscarriage. That said, it’s best to avoid high concentrations of cloves, such as those found in essential oils. If you have any concerns or uncertainties, consulting your healthcare provider is the safest approach.
Simple Methods to Use Cloves Regularly

Incorporating cloves into your daily routine is both simple and delicious. Try adding a teaspoon of ground cloves to your favorite baked goods, sauces, meat rubs, or marinades to enhance their flavor. You can also sprinkle a bit into chai, coffee lattes, or warm drinks for an extra kick. However, avoid consuming clove oil or clove water, as these often contain high concentrations of eugenol and other compounds that could be harmful. Always use cloves responsibly, and if you have any concerns, check with your healthcare provider before adding them regularly to your diet.
