Potion or Poison? Cloves

Abstract

SUMMARY MESSAGE: Eugenol contained in clove exhibits antimicrobial activity and has been shown to work synergistically with other conventional antimicrobials. There is evidence of clove's analgesic, anaesthetic, anti-inflammatory and antioxidant properties in low concentrations. High concentrations are toxic and can lead to tissue damage and hepatotoxicity. Avoid inhaling clove smoke, and avoid use in pregnancy and breastfeeding due to lack of safety and toxicity data. Eugenol has been shown to inhibit platelet aggregation and use should be avoided with anticoagulants and antiplatelet agents.
