The document summarizes a study examining the cytotoxic effects of creosote (Larrea tridentata) plant extracts on human lymphoma cell lines. A team of researchers from the University of Texas at El Paso and the University of Puerto Rico tested creosote leaf extracts on lymphoma cell lines and a non-transformed cell line. Their results suggest that the creosote extracts induce cell death in various lymphoma cell lines via apoptosis. The extracts also appear to protect cells from oxidative stress. While extracts from the creosote plant are used as herbal medicine in Mexico, U.S. and Canadian health organizations have issued warnings about potential organ damage. Further research is needed to fully understand the mechanisms of action and toxicity of compounds in the
