Synergistic combinations of TE and RE. Percent proliferating cells of control are represented as mean ± SEM and were determined by MTT assay on C2 (a), CMT-12 (b), and D17 (c) cell lines. TE and RE were used individually (dashed lines) or in combination at equal concentrations (solid line) at doses ranging from 0.8 to 25 μg mL−1. Lowest dose that induced a significant (p < 0.05) decrease in percent proliferation compared to DMSO control indicated by + (TE alone), # (RE alone), and ^ (dual extract combination)
