Methyleugenol is a component of essential oils and is found in basil, tarragon, nutmeg, and fennel.

When ingested through food, it can be converted in the liver into a reactive form that induces chemical alterations in DNA.

"These so-called methyleugenol-derived DNA adducts have already been detected in human liver tissue," explains Professor Dr.
