What it is

Cloves are the dried flower buds of a tropical tree from the Indonesian Spice Islands—the original centre of the global spice trade. The key active compound is eugenol (70–90% of clove essential oil), a potent local anaesthetic and antimicrobial. Cloves have one of the highest measured antioxidant capacities of any food.

Traditional use

Cloves were among the most prized spices in ancient trade routes. Used in Traditional Chinese Medicine for digestive warming, nausea, and pain. Used in Ayurveda as a warming digestive and dental analgesic. Sailors carried cloves to suck on for bad breath in the presence of the Emperor.

What modern research suggests (Promising)

Eugenol is an approved dental anaesthetic ingredient used in dental cement (zinc oxide eugenol). Studies show antimicrobial activity against oral pathogens, Candida, and food-borne bacteria. Antioxidant activity among highest of all natural substances. Anti-inflammatory effects comparable to aspirin in some studies. Some evidence for blood sugar reduction.

How people use it

For toothache: apply 1–2 drops of clove oil mixed with a carrier oil (1:5 ratio) directly to the affected tooth and gum. In food: add whole cloves or ground cloves to curries, chai, rice, marinades. As a digestive: a few whole cloves in herbal tea. Antimicrobial mouthwash: 2–3 drops in water for gargling.

Safety + interactions

Safe as a culinary spice. Undiluted clove essential oil is a strong irritant and should never be applied directly to gums, skin, or swallowed. Blood-thinning effect at high supplemental doses. Avoid using clove oil on small children's gums. May affect drug metabolism via CYP enzymes.

May interact with: Blood thinners, Medications metabolised by CYP enzymes

Quality notes

Eugenol content of clove oil should be 70–90%—check quality certificates. Clove buds should be fragrant and plump. Clove leaf oil has similar composition but different aroma and is cheaper. Bud oil is preferred for dental and therapeutic use. Always dilute essential oil—undiluted clove oil is a skin and mucous membrane irritant.
