About Clove
Clove (Syzygium aromaticum) bud is ~15–20% eugenol by mass — a phenolic compound with documented topical anesthetic, antimicrobial, and antioxidant activity. Strongest evidence is for topical dental use: eugenol-containing dental gels reduce post-extraction pain comparable to benzocaine in small RCTs. Oral supplementation for systemic effects (antimicrobial, anti-parasitic, blood-sugar) has minimal human RCT support — animal and in vitro work dominates. SAFETY: eugenol is hepatotoxic at high doses (case reports of pediatric liver failure from clove oil ingestion as little as 5–10 mL). Skin/mucosal irritation with undiluted oil. Inhibits platelet aggregation — additive bleeding risk with anticoagulants and NSAIDs. The clove-bud powder appearing in 'parasite cleanse' blends draws on traditional anti-helminthic claims without supporting RCT data.
What Clove supports
- Topical eugenol effective for dental analgesia (small RCTs)
- Clove oil overdose is hepatotoxic — case reports of pediatric liver failure
How much Clove to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
200–1000
mg
No validated oral therapeutic dose for systemic supplementation. Range reflects traditional culinary/herbal use. Topical eugenol 10–20% in dental gel has dose-finding studies; oral whole-clove dose-response data are essentially absent.
Clinical evidence
Limited clinical evidence. Topical dental analgesia is best-supported indication; systemic oral supplementation evidence is minimal and mostly traditional/mechanistic.
