- Syzygium aromaticum (L.) Merrill et L.M. Perry. Myrtaceae, dried flower buds, steam distillation. Eugenol 73.5–96.9% — highest eugenol driver trong cluster Clove × 3 + Cinnamon Leaf. Non-phototoxic. Same botanical species nhưng odor khác rõ rệt giữa bud / leaf / stem (T&Y Comments p.541).
- Hazards: Drug interaction + Methyleugenol + Anticoagulant + Embryotoxicity + Skin sensitization (moderate) + Mucous membrane irritation (moderate). Cautions oral: pethidine, MAOIs, SSRIs; anticoagulant meds, major surgery, peptic ulcer, hemophilia. Cautions dermal: hypersensitive/damaged skin, children <2y AVOID.
- Chemistry (Kubeczka 2002, Lawrence 1981 p.33–34, 1993 p.36): eugenol 73.5–96.9% + β-caryophyllene 0.6–12.4% + eugenyl acetate 0.5–10.7% + α-caryophyllene 0.4–1.4% + isoeugenol 0.1–0.2% + methyleugenol 0–0.2%.
- Max dermal: 0.5% (eugenol 0.5% IFRA cap, Tisserand & Young 0.5%). No oral cap specified in T&Y — multiple pediatric acute poisonings documented (Lane 1991 + Hartnoll 1993 + Janes 2005 = fulminant hepatic failure 10 mL).
- Methyleugenol (0–0.2%) is NOT dose-limiting — eugenol cap (0.5% oil) more restrictive than methyleugenol cap (10% oil at 0.2% methyleugenol × 0.0004% leave-on IFRA). Embryotoxicity signal (Domaracky 2007 mice 0.25%=375 mg/kg) is rationalized down by Amini 2003 pure eugenol 100 mg/kg no effect → no absolute pregnancy contraindication per T&Y.

Very easy to find as a spice or cheap imported essential oil. However, high-quality, unadulterated Clove Bud oil specifically extracted for aromatherapy is harder to find locally, as the market is flooded with industrial Clove Leaf oil labeled simply as "Clove Oil".
Pha Chế & Hòa Hợp
Strong local anesthetic, specifically for toothache and oral pain;
Ref: PMID 31869191 / PMID 37504233
Broad-spectrum action against bacteria and fungi due to high phenol content.
Reduces inflammation and swelling, particularly in joint/muscle blends;
Ref: PMID 26333873
PMID 31869191
Eugenol gel (2%) was as effective as 10% benzocaine in reducing acute toothache intensity.
Moderate RCTPMID 37504233
Eugenol was more effective than articaine for pain reduction on day one after emergency coronal pulpotomy.
Human RCTPMID 26333873
Clove oil exhibited significant antinociceptive, anti-inflammatory, and antipyretic effects in animal models.

Genuine: Should have a sweet-spicy note. Clove Bud is superior for aromatherapy compared to Clove Leaf or Stem (which are harsher and used mostly for industrial eugenol isolation). Adulteration risks: Frequently adulterated with cheaper clove leaf/stem oil or synthetic eugenol. Storage: Keep in dark, airtight bottles; prone to oxidation which increases sensitization risk.
