The meaning of cloves, in one line: warmth, protection, prosperity and a sweet mouth. In the Victorian language of flowers, cloves stood for dignity. In folk practice they are a guardian spice, burned to clear a room, carried to draw money and worked to stop gossip. And behind the symbolism sits a genuinely potent bud whose oil is still used by dentists. This is the full clove monograph: what it is, where the meanings come from, what the evidence says about clove for toothache, and how to use it without hurting yourself, because clove oil is one of the few kitchen remedies that can do real harm.

What clove is
A clove is the dried flower bud of an evergreen tree in the myrtle family that grows 8 to 12 metres tall and is native to the Maluku Islands of Indonesia, the original Spice Islands. The buds turn green and then bright red when ready for harvest, and are picked before they open and dried until hard and dark. The word comes, through Old French, from the Latin clavus, "nail", which is exactly what a clove looks like: a tapering shaft (the calyx) topped by a small round head of folded petals. Indonesia remains the largest producer, and uses most of its crop at home, much of it in kretek, Indonesian clove cigarettes.
The meaning of cloves
Clove symbolism grows out of three facts: it is hot, it smells overwhelming, and for most of history it was absurdly expensive. Each meaning traces back to one of those.
- Dignity. In Kate Greenaway's Language of Flowers, the Victorian dictionary of floral meanings, cloves are listed simply as "Dignity". A spice worth its weight in trade wars earns that.
- Warmth and affection. An orange studded with cloves makes a pomander, and Wikipedia records that in Victorian England such a pomander, given as a gift, "indicated warmth of feeling".
- A sweet, careful mouth. A Han dynasty text, the Han Guan Yi, is said to record a rule that ministers sucked cloves to sweeten their breath before speaking to the emperor. Fittingly, clove's folk use for stopping gossip is about the mouth too.
- Prosperity. Clove was a luxury that empires fought over, so it became a money spice in folk practice: carried, burned or tucked into a purse to draw abundance.
- Protection and banishing. Anything that hot and that pungent was always going to be cast as a guardian, and cloves are a staple of protection sachets and cleansing smoke.
All of these are traditional associations, not properties. They are worth knowing because they tell you why clove turns up where it does in ritual, and our wider guide to herbs and their meanings sets clove alongside the rest of the spice rack.
A short history of a very contested spice
Cloves travelled astonishingly far, astonishingly early. Archaeologist Giorgio Buccellati found cloves in a burned house at Terqa in Syria dated to around 1720 BC, thousands of kilometres from the only islands where they grew. In the 17th century the Dutch East India Company tried to monopolise the trade, which was harder than with nutmeg because clove trees grew all over the Moluccas. In 1770 agents acting on the instructions of the Frenchman Pierre Poivre smuggled seedlings off Ternate to Mauritius and the Seychelles, and the monopoly was finished. Today Indonesia, Madagascar, Tanzania, Sri Lanka and the Comoros lead production.
Appearance
The tree carries large, glossy leaves and clusters of buds that flush from green to crimson. Dried, each clove is a hard, reddish-brown to near-black nail about 1.5 to 2 cm long.
Fragrance and taste
The scent is deep, sweet, spicy and almost medicinal, the smell of a dentist's surgery and a Christmas ham at the same time, and a few buds will fill a room. The taste is hot and pungent with a numbing tingle that settles over the tongue and lips. That numbness is not poetic licence: it is eugenol doing what it does.
Constituents
Clove buds contain up to 18 percent essential oil, according to a 2020 review in Biomolecules, and that oil is dominated by eugenol, which makes up roughly 72 to 90 percent of it. Alongside sit eugenyl acetate, beta-caryophyllene and tannins. Eugenol gives clove its smell, its numbing action and its antiseptic reputation, and it is also the reason concentrated clove oil needs respect.
Herbal actions
Herbalists class clove as a warming, strongly antimicrobial spice, a local analgesic for the mouth, and a carminative that eases a windy, sluggish digestion. Nicholas Culpeper, writing in the 17th century, did not give clove a planet, but he did list it among his medicinal simples as hot in the third degree, and summed up its virtues in one breathless line:
"Cloves, help digestion, stop looseness, provoke lust, and quicken the sight."Nicholas Culpeper, herbalist, The Complete Herbal
Read that as history, not a prescription. The digestive use survives in modern herbal practice; the eyesight claim does not.
Clove for toothache: what the evidence says
This is where clove's reputation is genuinely earned. Eugenol is a working dental material: mixed with zinc oxide it forms zinc oxide eugenol, used as a cement and temporary filling. In a small randomised, blinded study of 73 adults, a homemade clove gel numbed the gum before a needle stick about as well as 20 percent benzocaine gel, and both beat placebo.
The European Medicines Agency recognises clove oil as a traditional herbal medicine for minor mouth and throat inflammation and for temporary relief of toothache from a cavity, applied on cotton wool to the decayed tooth and avoiding the gums. It is equally clear about the limits.
"The relief of toothache by clove essential oil is only a provisional measure. Dental attention should be sought as soon as possible."European Medicines Agency, Committee on Herbal Medicinal Products, Community herbal monograph on clove oil
Clove will buy you a quieter night. It will not fix the tooth. Book the dentist.
Clove in astrology and correspondences
Clove arrived in Europe as an imported luxury rather than a garden plant, so it sits outside the old planetary herbals; Culpeper listed it without a ruler. Modern folk correspondence links clove with Jupiter, the planet of expansion and plenty, with a solar warmth to it, and with the element of Fire. It suits the personality: hot, generous, protective and a little bit extra. If you want to know where Jupiter sits in your own chart before you build a prosperity ritual around it, the birth chart calculator will show you. Treat all of it as symbolic language, not evidence.
Magical uses: rituals clove is good for
- Protection. Add whole cloves to a protection sachet or scatter a few along a threshold.
- Cleansing and banishing. Burn a few cloves on charcoal to clear heavy air; they are one of the warmer choices among herbs for smoke cleansing. Ventilate: clove smoke is strong.
- Drawing money. Tuck cloves into a purse or a jar of money herbs, often with cinnamon.
- Stopping gossip. Traditionally worked to quiet unkind talk, which is the same mouth-sweetening theme as those Han ministers.
- Warmth and welcome. A clove pomander for a home, or as a gift that, by Victorian rules, says you are fond of someone.
A Southern Hemisphere note
Clove's whole seasonal identity, mulled wine, pomanders, roaring fires, is built on a Northern Hemisphere Christmas. In Australia that collides with a 35 degree December. Two easy fixes: make your pomanders for the winter solstice in late June instead, when our nights are actually long (our winter solstice ritual pairs well with one), or keep clove for summer in its other role, a cold spiced tea with orange peel and ginger.
How to use clove
- In the kitchen. Whole or ground in baking, rice, curries, pickles and spiced drinks. This is the safest and most useful form.
- As a warming tea. Simmer two cloves with a slice of ginger and a cinnamon stick for ten minutes.
- For a toothache, short term. Adults only: a commercially prepared clove oil product on cotton wool, applied to the tooth not the gum, for no more than a week while you wait for the dentist.
- In ritual. Whole buds in sachets, jars and pomanders, or a few burned for cleansing. Our guide to herbal preparations covers infusions and other forms.
Is clove safe?
As a culinary spice, yes. Concentrated clove oil is a different matter, and the cautions are serious.
- Keep clove oil away from children. The EMA monograph records life-threatening reactions after children under two swallowed 5 to 10 ml of clove oil, including liver damage, seizures, coma and low blood sugar. It does not recommend clove oil products for anyone under 18. Store it like a medicine. If a child swallows clove oil, call the Poisons Information Centre on 13 11 26 (24/7, anywhere in Australia), or 000 in an emergency.
- Never take clove oil internally. Neat eugenol irritates and burns tissue. Avoid contact with the gums, and stop if your mouth becomes irritated.
- Allergy. The EMA lists allergy to Peru balsam as a contraindication, and mucosal irritation and allergic reactions have been reported.
- Pregnancy and breastfeeding. Safety has not been established, so medicinal clove oil is not recommended. Food amounts are fine.
- Liver, bleeding or immune conditions. Medicinal clove taken by mouth may cause adverse effects in people with liver disease, blood clotting or immune system disorders, or food allergies, so talk to your doctor first.
Herbalism is a complement to medical and dental care, not a substitute for it.
Common mistakes with clove
- Treating clove oil as a cure. It numbs; it does not treat decay or infection. A tooth that keeps hurting needs a dentist.
- Pouring neat oil onto the gum. That is how people end up with a chemical burn on top of a toothache.
- Leaving the bottle where children can reach it. Small amounts have caused severe poisoning in toddlers.
Does clove really work?
For a temporary numbing of the mouth, yes, with real evidence and a formal EMA recognition behind it. For digestion, it is a sensible warming spice with long tradition. For money, protection and silencing gossip, clove works the way all symbolism works: by making you stop and mean something. I keep a jar of whole cloves for winter simmering and a pomander or two in June, and the oil lives in a locked cabinet, which is exactly where its potency belongs.

Frequently asked questions
The meaning of cloves centres on warmth, protection, prosperity and dignity. In the Victorian language of flowers cloves stood for dignity, and a clove-studded orange pomander given as a gift signalled warmth of feeling. In folk practice clove is a protective, cleansing spice, carried to draw money and traditionally worked to stop gossip. These are symbolic associations rather than proven effects.
Cloves symbolise protection, banishing and abundance spiritually. Their heat and strong scent cast them as a guardian spice for protection sachets and cleansing smoke, while their history as one of the world's most expensive spices made them a symbol of wealth. Modern folk correspondence links clove with Jupiter and the element of Fire. Treat these as traditional associations rather than fact.
Clove oil really can help toothache for a short time. Its main compound, eugenol, numbs tissue, a small trial found clove gel numbed the gum about as well as benzocaine, and the European Medicines Agency recognises clove oil as a traditional remedy for temporary toothache relief. It is only a stopgap, though: it does not treat decay, so see a dentist as soon as possible.
Clove oil is not safe to swallow and must be used with care. The European Medicines Agency records life-threatening poisoning in children under two after 5 to 10 ml, and does not recommend clove oil products for under 18s. Keep it locked away, apply it only to the tooth rather than the gum, and avoid medicinal use in pregnancy. Culinary cloves are safe.
The planet that rules cloves in modern folk correspondence is Jupiter, with the element of Fire. Clove reached Europe as an imported luxury rather than a garden herb, so Nicholas Culpeper did not assign it a planet, though he did list it as a hot medicinal simple. The Jupiter link reflects clove's warm, generous, protective character and its long association with wealth.
You use cloves for protection by adding whole buds to a protection sachet, scattering a few along a threshold, or burning a small number on charcoal to clear a room, with the window open because the smoke is strong. Many people pair them with cinnamon or bay. This is a traditional ritual practice rather than a proven effect, so enjoy it for its meaning.
Cloves come from the dried, unopened flower buds of an evergreen tree, Syzygium aromaticum, native to the Maluku Islands of Indonesia, the original Spice Islands. The buds turn from green to bright red before harvest and are dried until hard and dark. Indonesia is still the largest producer, followed by countries including Madagascar, Tanzania, Sri Lanka and the Comoros.
