Cloves (Syzygium aromaticum) are the dried flower buds of an evergreen tree native to the Maluku Islands of Indonesia, widely celebrated for their rich aroma, bold flavour, and impressive range of health benefits. Long used in West African and Ghanaian cooking, from spiced stews to herbal teas cloves pack a remarkable punch of bio active compounds that modern science is now validating. The health benefits of cloves span everything from fighting inflammation and supporting oral health to regulating blood sugar and protecting the liver.
Key Takeaways
- Cloves are one of the richest antioxidant spices available, primarily due to a compound called eugenol.
- Their anti-inflammatory and antimicrobial properties make them valuable for oral health and fighting common infections.
- Cloves may help regulate blood sugar levels, making them particularly relevant for people managing or at risk of diabetes.
- They are widely used in Ghanaian and West African traditional medicine and cuisine.
- Moderation matters: large doses or concentrated clove oil can carry health risks.
What Makes Cloves So Powerful?
The secret behind the health benefits of cloves lies in their dense concentration of bio active compounds. The most important of these is eugenol, a natural phenol that gives cloves their distinctive warm, pungent scent. According to a 2025 study published in ACS Omega (NIH/PubMed), eugenol demonstrates potent antioxidant and anti-inflammatory activity in vitro, confirming centuries of traditional use.
Beyond eugenol, cloves contain:
- Flavonoids and polyphenols compounds that help neutralise harmful free radicals in the body
- Manganese — a trace mineral critical for bone formation and metabolic function
- Vitamin C, Vitamin K, and B vitamins — all important for immunity, clotting, and energy metabolism
- Fibre — supporting healthy digestion
According to Nutrition and You, the active principles in cloves include antioxidant, antiseptic, local anesthetic, anti-inflammatory, and carminative properties, making this humble spice a true nutritional all-rounder.
Top Health Benefits of Cloves
1. Powerful Antioxidant Protection
Cloves rank among the highest of all foods on the ORAC (Oxygen Radical Absorbance Capacity) scale, meaning they are extraordinarily effective at neutralising free radicals. WebMD notes that antioxidants help your body fight free radicals that damage cells reducing the risk of chronic diseases like heart disease and cancer.
Eugenol in particular has been shown to act as a natural antioxidant, and including cloves in your daily diet alongside other antioxidant-rich foods can meaningfully help reduce oxidative stress throughout the body.
2. Anti-Inflammatory Effects
Chronic inflammation is at the root of many serious health conditions, including arthritis, heart disease, and metabolic disorders. The eugenol in cloves has been shown to reduce the body's inflammatory response. WebMD highlights that this anti-inflammatory action can lower your risk of health issues such as arthritis and help manage existing symptoms.
For Ghanaians who rely on traditional remedies for joint pain and body aches, cloves used in food and herbal teas offer a gentle, evidence-backed complement to conventional care.
3. Exceptional Oral Health Support
One of the best-established health benefits of cloves is for oral health. Eugenol has been used in dentistry for over a century, dentists still use zinc oxide and eugenol (ZOE) compounds for root canal fillings and temporary dental cements. As Medical News Today explains, people have used clove oil for centuries to relieve tooth pain, and its analgesic properties are well supported by science.
Cloves also have broad-spectrum antibacterial activity against oral pathogens like Streptococcus mutans, a key cause of tooth decay. Adding cloves to your oral hygiene routine, through a clove-infused mouth rinse or by gently chewing a dried clove, can meaningfully support gum and tooth health.
4. Blood Sugar Regulation
Emerging research suggests cloves may help regulate blood sugar levels a benefit with significant relevance for Ghanaians, given the growing prevalence of diabetes in the country. The compound nigericin found in cloves appears to enhance glucose uptake by cells, potentially improving insulin sensitivity.
Healthline reports that the compounds found in cloves may help keep blood sugar under control, and animal studies have demonstrated promising results. If you are already managing diabetes, speak with your doctor before adding clove supplements but using cloves as a culinary spice is generally safe and may offer gentle blood sugar support.

5. Liver Protection
The liver is your body's primary detoxification organ, and cloves may help keep it healthy. Healthline notes that studies have found eugenol may help reduce signs of liver cirrhosis and fatty liver disease. The antioxidant activity in cloves helps reduce oxidative stress in liver cells, offering a degree of hepatoprotective (liver-protecting) benefit.
Important note: while moderate culinary use of cloves is liver-friendly, high-dose clove oil supplementation can cause liver damage, so more is definitely not better.
6. Antimicrobial Properties
Cloves have significant antimicrobial properties, inhibiting the growth of bacteria including E. coli and Staphylococcus aureus. As Healthline highlights, clove oil can help stop the growth of microorganisms that cause food poisoning and infections.
This antimicrobial quality is one reason cloves have been used for centuries as a food preservative in tropical climates like West Africa, where foodborne illness risk can be elevated during warmer months.
7. Digestive Support
Cloves act as a natural carminative, helping to relieve gas, bloating, and indigestion. The fibre in cloves supports healthy bowel movement, while eugenol helps soothe the lining of the gut. A warm cup of clove tea after a heavy meal is a time-honoured remedy across Ghana and across the continent for settling an upset stomach.
Cloves in Ghanaian Culture and Cuisine
Cloves are one of Ghana's most widely used spices in cooking, appearing in soups, stews, rice dishes, and spiced teas. Their prominent place in local culinary tradition is well recognised, and many Ghanaian households reach for cloves as a natural remedy for toothaches, colds, and digestive troubles, a practice that science is increasingly validating.
Beyond cooking, cloves feature in many West African herbal preparations. Their warming, aromatic properties make them a staple in home remedies passed down through generations, and their affordability and availability at any local market makes them accessible to all.
How to Use Cloves Safely
Culinary use (safest method):
- Add 2–4 whole cloves to soups, stews, rice, and marinades
- Brew 2–3 cloves in hot water for a warming spiced tea
- Use ½ teaspoon of ground cloves in baked goods or spice blends
Topical use for toothache:
- Dilute 2–3 drops of clove essential oil in 1 teaspoon of a carrier oil (e.g., coconut oil) before applying to the gum. Never apply undiluted clove oil directly to skin or mucous membranes
Safe daily intake: 1–3 whole cloves per day in food is generally considered safe for most healthy adults.
Caution:
- Concentrated clove oil can cause liver toxicity in high doses, especially in children
- Cloves have mild blood-thinning properties speak to your doctor if you are on anticoagulant medication
- Pregnant women should avoid large supplemental doses of cloves
