Cloves and How They Help Us

Unlike many culinary herbs, clove isn’t a leaf or a seed. It’s the dried, unopened flower bud of an evergreen tree that is harvested before it blooms. Its English name comes from the latin “clāvus” which translates to “nail”, referring to the odd shape of the bud.

Alongside its role as a spice, it can be added to food to help preserve it, chewed to freshen breath and used to ease tooth pain.

Traditional uses

Clove has a long association with pain relief, particularly dental pain. Before modern anaesthetics, clove was commonly used to numb toothaches, either by chewing the bud or applying clove oil to the affected area.

It was also used to support digestion. Clove’s warming nature made it useful after heavy meals, helping with gas, bloating, and sluggish digestion.

In many traditions, it appears alongside other spices like cinnamon, ginger, and cardamom, not as a standout ingredient but as part of a supportive whole – like in chai, for example.

Clove was also valued for its ability to keep food fresh. Long before refrigeration, spices with antimicrobial properties mattered. They weren’t just about taste, they were practical additions to everyday cooking.

What modern research shows

Much of clove’s activity comes from a compound called eugenol, which makes up a large percentage of clove’s essential oil. Eugenol has been studied for its antibacterial, antifungal, and pain-relieving properties, which helps explain many of clove’s traditional uses.

Clove is particularly rich in antioxidants. These compounds help protect cells from oxidative stress, which plays a role in inflammation and chronic disease. Foods high in antioxidants tend to support overall resilience in the body. Even small amounts of clove contribute here, because it’s so concentrated.

Research has also looked at clove’s effects on oral health. Studies suggest clove oil can inhibit bacteria associated with cavities and gum disease, supporting its long history in dental care. This is why eugenol is still used in dentistry today, though in controlled forms.

There’s some evidence that clove may help with blood sugar regulation and liver health, mainly from animal and laboratory studies. These findings are promising but still early, and they don’t mean clove should be used medicinally in large amounts. They do, however, reinforce the idea that clove’s effects go beyond flavour alone.

Clove oil has also been shown to have analgesic effects when used topically in very small, diluted amounts. The numbing sensation it creates is real, but it’s also where caution is most important.

Simple ways to use clove

In cooking
- Whole cloves can be added to stews, broths, rice dishes, or mulled drinks, then removed before serving. Ground clove works well in baking, especially alongside cinnamon or nutmeg. A light hand matters here.
Digestive support
- A clove or two added to herbal tea blends can bring warmth and depth. It’s often paired with ginger or fennel rather than used alone.
Oral care
- Historically, whole cloves were chewed to freshen breath. This is still common in some cultures, though it should be occasional rather than habitual.
Around the home
- Clove’s strong scent makes it useful in natural moth or insect deterrents. It’s often combined with citrus peel or cinnamon sticks.

Growing and sourcing clove

Clove trees grow in tropical climates and aren’t suited to most temperate gardens. For most of us, clove is something we source rather than grow.

Buying whole cloves rather than pre-ground helps preserve their flavour and potency, and they last surprisingly well when stored properly.

If possible, choose cloves from suppliers that focus on ethical sourcing, as clove production has a long and complicated history tied to colonial trade.

Cautions

Clove is safe in culinary amounts for most people, but its essential oil is extremely strong. Undiluted clove oil can cause burns, irritation, or allergic reactions, and it should never be used internally without professional guidance.

Clove oil is not suitable for children, and even for adults it should be treated with respect. More is not better here. Small, occasional use is where clove does its best work.

If you’re pregnant, breastfeeding, or managing a medical condition, it’s sensible to check before using clove in concentrated forms.
