Identity & origin
BOTANICAL IDENTITY
The right name is the first step.
Clove tree: guidance on the flower bud and flower-bud essential oil, with the uses and precautions specific to documented preparations.
Also known as: clove
The botanical name and part used must match the profile; a photograph alone is not sufficient grounds for consuming a plant.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
Uses & evidence
UNDERSTANDING THE USES
Properties & uses.
Temporary toothache
Traditional use of an essential oil preparation for pain related to tooth decay while awaiting dental care.
Use considered plausible in a traditional-use monograph. That status alone does not demonstrate clinical efficacy.
Read the sourceMouth and throat
Traditional local use for minor inflammation; the whole clove has no equivalent monograph.
Use considered plausible in a traditional-use monograph. That status alone does not demonstrate clinical efficacy.
Read the sourceThe traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.
Precautions before use
BEFORE ANY USE
Precautions & contraindications.
This guidance does not cover every individual situation. Missing information is not a guarantee of safety.
Contraindications & precautions
- Source-listed contraindicationAllergy to clove oil or Peru balsam: contraindication.Source
- PrecautionTemporary dental use while awaiting care; avoid direct gum contact. Mucosal irritation and allergy are possible. Do not ingest essential oil in a home recipe.Source
Medicine interactions
- No interaction reported in the sourceNo interactions are reported in the source for the assessed preparations. Evidence is limited; compatibility with medicines is not guaranteed.Source
“Reported” does not prove causality; “possible” may reflect indirect evidence. “None reported” means none in the cited source, not that all combinations have been studied. Do not stop a prescribed treatment based on this profile.
Adverse effects
- Irritation and allergy possible; this profile does not define a safe dilution.
Pregnancy & breastfeeding
Medicinal use is not recommended during pregnancy or breastfeeding because evidence is insufficient; missing evidence establishes neither harm nor safety.
SourceChildren & adolescents
Medicinal use is not recommended below age 18 because evidence is insufficient; do not scale down an adult dose.

EXPLORE THE EVIDENCE
How does the plant act?
The clove tree shows why food use and a medicinal preparation must be distinguished. The EMA assessment mainly concerns the flower bud essential oil for certain temporary local uses in the mouth. The whole clove has not received the same therapeutic monograph. Antimicrobial or anesthetic activity observed in the laboratory does not make it safe to apply concentrated oil to a mucous membrane.
Constituents to know.
Their presence and quantity depend on the plant part and preparation.
- Eugenol
- A major constituent of the essential oil, studied for local effects on pain and microorganisms; it can also irritate and sensitise.Read the reference
Temporary dental relief
Traditional use of local formulations does not treat the cause of toothache or remove the need for a dentist.
Use considered plausible in a traditional-use monograph. That status alone does not demonstrate clinical efficacy.
Read the referenceLaboratory activities
Antimicrobial and analgesic observations with the oil or eugenol do not demonstrate treatment of an oral infection.
Laboratory or animal observation. A human benefit cannot be inferred from this finding alone.
Read the referenceWhat this means for preparation.
A pure essential oil is not a ready-to-use mouthwash. Products must be formulated for the intended use and their tolerability checked, particularly in cases of allergy.
Studies, findings & limitations
THE RESEARCH
What the research shows.
A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.
Flower bud or oil?
Use considered plausible in a traditional-use monograph. That status alone does not demonstrate clinical efficacy.
- Type of research
- Shared EMA report examining the flower bud and its essential oil.
- Preparation concerned
- Syzygium aromaticum, forms and compositions assessed separately.
- Observed results
- The accepted traditional-use framework for the oil concerns a specific local oromucosal route.
- Limitations to consider
- The whole clove dossier is insufficient for a positive monograph; neither herbal tea nor ingestion of essential oil can be inferred from the local findings.
What can we take from this?
A temporary reduction in pain can mask dental damage. The guide provides no home protocol for anesthesia or ingestion of essential oil.
