Fig. 3: Growth inhibitory activity of combinations of phytochemicals: TriCurin (90 or 95% curcuminoids) plus tanshinone IIA on HeLa cells.

a, b Combination of TriCurin (90% curcuminoids) plus tanshinone IIA. a x-axis: TriCurin (90% curcuminoids); b x-axis: tanshinone IIA; c, d combination of TriCurin (95% curcuminoids) plus tanshinone IIA; c x-axis: TriCurin (95% curcuminoids); d x-axis: tanshinone IIA. We treated HeLa cells with all combinations of four concentrations of each of the agents tested and a solvent control.18 Cells were exposed to increasing concentrations of agents for 96 h and the number of viable cells was determined by the EZQUANT assay.
