Clove: Benefits, Uses & Dosage

If you have ever pressed a clove against an aching tooth, you already know what this little spice can do. Within minutes the sharp pain dulls, and you notice a curious cool, numbing feeling as you breathe in through your mouth. That one experience sums up why Ayurveda treats Clove (Lavanga) as far more than a kitchen flavouring.

Cloves are the dried, unopened flower buds of the clove tree, known botanically as Syzygium aromaticum. The fruits, called mother cloves, are also used. Classical texts know the spice by several Sanskrit names, including Devapushpa and Devakusuma. The Sharangadhara Samhita uses the name Devapushpa when it recommends cloves in the diet for abdominal colic.

What makes cloves distinctive is a paradox. They taste pungent and bitter, yet the Bhavaprakash Nighantu classes their potency as cooling (Sheeta Virya), which makes them unusual among spices. Some modern Ayurvedic sources describe them as heating instead, and this page notes where that difference matters.

The bud is rich in a volatile oil, up to 20% by weight, dominated by eugenol, a compound with strong antiseptic and pain-relieving action. That chemistry explains the classic dental use, while the classical texts add digestion, nausea, cough, breathing and the heart to the list of things cloves support.

The Bhavaprakash Nighantu lists nine therapeutic actions (Karma) for cloves. Grouped by body system, they cover a surprising amount of ground for one small bud.

Digestion and Appetite

Cloves are classed as an appetizer (Dipana), a digestive (Pachana) and a taste enhancer (Ruchya). In plain terms, they wake up a sluggish digestive fire, help you actually process a meal, and bring back interest in food when appetite is low.

That is why they are used for indigestion, loss of appetite and gas and bloating. The Sharangadhara Samhita names cloves among the foods that are beneficial in abdominal colic, alongside substances that move Vata (the dosha of air and movement) downward in the gut (Anulomana).

Nausea, Vomiting and Hiccups

Cloves are an antiemetic (Chhardighna), meaning they settle nausea and vomiting. A common pairing is cloves with cardamom and ginger for nausea. Cloves are also used for hiccups, and a pinch of clove with saffron and nutmeg in yogurt is a traditional home approach to diarrhea.

Cough, Breathing and Congestion

Classically, cloves relieve cough (Kasaghna) and ease difficult breathing (Shwasahara). Their pungent taste and penetrating quality cut through Kapha, the heavy, mucus-forming dosha, which is why they act on sinus and bronchial congestion.

They are used for cough, colds and flu, asthma, chest congestion, allergic rhinitis, sore throat and a hoarse voice.

Teeth, Gums and Mouth

This is the best known use. Eugenol in clove oil is both antiseptic and analgesic, so cloves are a first-line home remedy for toothache and other tooth disorders, and the Bhavaprakash Nighantu also describes them as anti-parasitic (Krimighna) and analgesic for the tooth root, relevant to a dental abscess.

The Sushruta Samhita recommends betel leaf with cloves, camphor, nutmeg and lime for mouth cleansing, an early classical approach to oral hygiene.

Heart, Eyes and Burning Sensations

Cloves are listed as a heart tonic (Hridya), as beneficial for the eyes (Chakshushya), and as relieving burning sensations (Dahashamaka). That last action ties back to their cooling potency, which classical sources credit with calming Pitta, the dosha of heat.

Reproductive Vitality

Cloves are described as an aphrodisiac and are used for impotence, typically combined with ashwagandha, shatavari and nutmeg. They act on the reproductive tissue and channels according to their classical profile.

Cloves are strong, so a little goes a long way. The general dosage range for dried clove powder is 1 to 3 grams per day, and most home remedies use far less: a single pinch at a time. The right vehicle (Anupana), meaning the food or liquid you take an herb with, steers what the clove does.

Choosing a Vehicle

Raw honey is the most common carrier for clove in respiratory and digestive remedies. Never heat the honey. Trikatu, a classical blend of ginger, black pepper and long pepper, is added when the goal is a stronger push to digestion.

Clove Oil Externally

Clove essential oil is highly concentrated. For the gums or skin, dilute it, roughly 1 drop in 1 teaspoon of coconut or sesame oil, rather than applying it neat for long stretches. Clove oil is also blended into massage oils, such as with ginger oil in Narayan oil for arthritis, sciatica and pain.

Cloves are a common kitchen spice and are safe for most people in food amounts. The cautions come with medicinal doses and, above all, with concentrated clove oil.

Contraindications

• High Pitta and inflammatory conditions. Sources disagree on whether cloves are heating or cooling, but all agree that people with a lot of heat in the body should use them carefully. Some sources state plainly that cloves increase Pitta.
• Active gastritis, peptic ulcer or reflux. Avoid high doses and keep clove oil away from internal use.

Drug Interactions

One classical-based source reports no known drug and herb interactions. However, eugenol has mild blood-thinning activity, so if you take warfarin, aspirin or another anticoagulant, stick to kitchen-spice amounts and talk to your doctor before using medicinal doses.

Pregnancy and Nursing

Food amounts, such as a few cloves in cooking, are considered safe in pregnancy. Avoid medicinal doses of clove powder and any internal use of clove oil unless a qualified practitioner is guiding you.

Signs You Are Taking Too Much

Stop or cut back if you notice burning in the nose, mouth ulcers or stomach irritation. These are signs the pungency is outpacing the cooling action for your constitution. Stay under about two grams of powder a day for regular use.

Clove Oil

Never swallow clove essential oil neat, never use it undiluted on gums or skin for long periods (eugenol can burn mucous membranes), and never put it in the ear if the eardrum may be perforated or there is discharge.

Rasa (Taste): Pungent, Bitter

Virya (Energy): Heating

Vipak (Post-digestive effect): Pungent

Dosha: Increases pitta, decreases vata and kapha

A good digestive stimulant and acts on sinus and bronchial congestion.

• Cold or cough: 1 teaspoon of honey mixed with a pinch of clove, 2 or 3 times a day.
• Indigestion and low appetite: 1 pinch of clove powder, ¼ teaspoon trikatu and 1 teaspoon of honey, 5 minutes before food.
• Hoarseness of voice: A pinch each of clove and cardamom powder, ½ teaspoon ground licorice root and 1 teaspoon of honey, mixed well and eaten slowly.
• Diarrhea: A pinch each of clove, saffron and nutmeg powders mixed into ½ cup of yogurt, taken twice a day.
• Toothache: Apply a drop of clove oil on the tooth.

Cloves often sit in the same spice jar, and the same remedies, as a few other herbs. Here is how they differ in the situations people ask about most.

Cloves are a food as well as a medicine, so the main question for any group is dose and form. Whole cloves and small pinches of powder are gentle; concentrated clove oil is not.

Pregnancy and Nursing

A few cloves in cooking, or sucking a single clove, are considered food-level and safe in pregnancy. Avoid high-dose clove powder and any internal use of clove oil without a practitioner's guidance, and take extra care if pregnancy comes with reflux. Persistent hiccups or other symptoms in pregnancy need medical evaluation rather than stronger herbal doses. The same food-level approach is the cautious choice while nursing.

Children

Skip clove essential oil entirely in children. Whole cloves are generally avoided under age six because the eugenol is too strong for thin, delicate mouth tissue. For younger children, a warm, cooled clove tea (one clove simmered in a cup of water with cinnamon and honey) is the gentler option. School-age children who can chew without swallowing pieces can usually tolerate a single clove held at a sore tooth, but tooth pain in a child should be seen by a dentist within a day or two.

Elderly

Older adults can use cloves at ordinary food and home-remedy doses. Because medications are more common in later life, note that eugenol has mild blood-thinning activity: if you take warfarin, aspirin or another anticoagulant, keep to kitchen-spice amounts and check with your doctor first.

People Who Run Hot

If you have a strong Pitta constitution or an inflammatory condition, use cloves in small amounts and pair them with cooling partners such as cardamom. Stop if you notice burning in the nose, mouth ulcers or stomach irritation.
