Essential oils from the verbena family of plants found to protect against liver and lung cancers
Institute of Biological Investigation (Argentina), September 2, 2019
A study published in the Journal of Essential Oil Research investigated the anti-proliferation effect and cytotoxicity of the essential oil from a species of flowering plant called Lippia alba or verbena on human liver and lung cancer cells.
In the current study, the researchers evaluated the essential oils from L. alba (LaEOs) for their cytotoxicity on human cancer culture cells and the mechanisms involved. They found that the LaEOs exhibited selective cytotoxicity against human hepatocarcinoma cell HepG2 (liver cell line) and human alveolar basal epithelial cell A549 (lung cell line). The mechanism involved cell cycle arrest and apoptosis induction. Based on these results, the researchers concluded that tagetenone chemotype could be a chemopreventive and chemotherapeutic agent against human liver and lung cancers.
