Some research suggests that the clove oil might help protect against cancer.
Specifically, eugenol has been shownTrusted Source to have anticancer properties. Specifically, test-tube researchTrusted Source suggests eugenol promotes cell death in breast cancer cells.
However, as stated, eugenol is toxic in high amounts, and overdosing on clove oilTrusted Source may cause liver damage, especially in children. Further research is needed to determine how lower amounts may affect humans.
Cloves have been shownTrusted Source to have antimicrobial properties, meaning they can help stop the growth of microorganisms like bacteria.
