The main constituents of Ocimum basilicum essential oil: rosmarinic, caffeic acid, eugenol, isoeugenol and linalool were tested against four human cancer cell lines and were found more effective than the corresponding extract or oil, with the isoeugenol being the major constituent of O. Basilicum essential oil acting as a cancer cell inhibitor. From: Zarlaha, A., Kourkoumelis, N., Stanojkovic, T. P., & Kovala-Demertzi, D. (2014).
