Cytotoxicity of BBR and herbal extracts. Cells were grown in 96 well plates and treated with the indicated substances for 1, 3 and 5 days or during differentiation. Cell viability was measured using a resazurin-based in vitro toxicology assay. (A) HuH7 cells, (B) undifferentiated 3T3-L1 cells, (C) differentiated 3T3-L1 cells and (D) 3T3-L1 cells treated during the differentiation process. Error bars are based on the SEM of 3 independent experiments.
