The alkenylbenzene methyleugenol occurs naturally in a variety of spices and herbs, including basil, and their essential oils. At high dose levels methyleugenol induces hepatocarcinogenicity in rodents following bioactivation to 1'-sulfooxymethyleugenol which forms DNA adducts. This study investigated whether the
